Referring to fig. 1 to 4, the high altitude lifting apparatus according to the embodiment of the present invention includes a ladder 5, a lift (not shown), a switching part 1 and a traction part 4. Wherein the lifter is suitable for lifting along the extending direction of the ladder 5; the switching member 1 is mounted to the ladder 5 and the switching member 1 is configured to control the elevator braking in case of triggering; the traction part 4 is arranged along the extending direction of the ladder 5, the first end of the traction part 4 is connected to the ladder 5, the second end is connected to the switch part 1, and the traction part 4 is suitable for triggering the switch part 1 under the action of external force.

According to the high-altitude lifting equipment provided by the embodiment of the invention, the traction part 4 is arranged along the extending direction of the ladder stand 5, so that the switch part 1 can be triggered by pulling the traction part 4 in the climbing process of a climber, and the purpose of controlling the braking of the lifter is achieved. This kind of high altitude elevating equipment can avoid personnel to climb along cat ladder 5 while the casualties that the lift motion leads to have promoted the security of high altitude elevating equipment operation.

The "extending direction of the ladder 5" refers to the longitudinal direction of the ladder 5, that is, the up-down direction in fig. 1.

According to the embodiment of the invention, the high-altitude lifting equipment further comprises a plurality of limiting ring parts 3 fixed on the ladder stand 5, the limiting ring parts 3 are distributed along the height direction of the ladder stand 5, and the traction part 4 penetrates through the limiting ring parts 3. Through the setting of spacing ring part 3, required trigger distance when can reduce switch block 1 and be triggered to improve switch block 1's triggering accuracy, guarantee high altitude jacking equipment's security. The triggering distance is understood to mean the amount of deformation or displacement of the traction means 4 when the switching element 1 is triggered. The larger the triggering distance is, the larger the operation range the climber needs to be to trigger the switch component 1, and the greater the difficulty of triggering the switch component 1 at this time is. And through the setting of spacing ring part 3, can reduce the distance that triggers, reduce the degree of difficulty that triggers switch part 1, guarantee climbing personnel's safety. By arranging the spacing ring part 3, the length of the traction part 4 of the connection switch part 1 can be prolonged on the premise of ensuring the triggering reliability. For example, in the case that the spacing ring part 3 is not provided, the length of the traction part 4 corresponding to the switch part 1 can be 30 meters, and by providing the spacing ring part 3, the switch part 1 can still be effectively triggered when the length of the traction part 4 is increased to 150 meters.

According to the embodiment of the invention, the stop collar parts 3 are evenly distributed along the extending direction of the ladder 5, for example, one stop collar part 3 can be arranged at intervals of a specific number of steps (the steps of the ladder 5 can be in the form of pedals 501, rungs or any other structures which can be climbed by people) so as to effectively control the triggering distance of the traction part 4 when the switch part 1 is triggered. The smaller the spacing between adjacent stop collar segments 3, the smaller the triggering distance. However, the spacing of the stop collar part 3 is not as small as possible because: when the spacing between the spacing ring parts 3 is very small, the required trigger force value is relatively large, and the trigger difficulty of the switch part 1 is increased. Wherein, the triggering force value refers to the force value which is required to be acted on the traction component 4 by the climbing personnel when the switch component 1 is triggered. In the embodiment of the invention, the distance between the adjacent limiting ring parts 3 can be set to be between 2m (meter) and 4m, and the required triggering distance and the triggering force value are not too large. Wherein, when the distance between the adjacent spacing ring parts 3 is 3m, the triggering performance of the traction part 4 to the switch part 1 is best.

According to the embodiment of the present invention, the traction component 4 may be a flexible cable, such as a steel cable, other metal rope or other structure with certain tension and flexibility; of course, the traction means 4 may also be a traction bar.

According to an embodiment of the invention, the aerial lift device further comprises a tensioning member 2 adapted to generate a pretensioning force to the wire. The tensioning element 2 ensures that the cable is pre-tensioned and that the switching element 1 is triggered by applying a small force to the cable. The type of tensioning member 2 is very numerous and can take any form of construction already disclosed in the prior art, as long as the tensioning requirements of the flexible cable are met. For example, the tensioning element 2 may be arranged between two lengths of wire in the direction of extension of the ladder 5, as shown in figure 1. Specifically, the flexible cable comprises a first flexible cable section and a second flexible cable section, the tensioning part 2 is arranged between the first flexible cable section and the second flexible cable section along the extending direction of the ladder 5, and two ends of the tensioning part 2 are respectively connected with the first flexible cable section and the second flexible cable section. Further, the first wire segment and the second wire segment can be placed in a tensioned state by the tensioning member 2. For another example, the tension member 2 may also be in the form of a tension wheel.

According to an embodiment of the present invention, please refer to fig. 2, the switch component 1 comprises a first mounting seat and a switch body 106. At this time, the switch body 106 is fixed to the ladder 5 by the first mount. Of course, the switch member 1 may not be provided with the first mounting seat, and in this case, the switch body 106 may be directly fixed to the ladder 5 by welding, bonding, screwing, or the like.

In one embodiment, the first mounting seat comprises a first mounting plate 101 and a first fixing plate 102 detachably disposed on a first side of the first mounting plate 101, a first clamping groove 109 is formed between the first fixing plate 102 and the first mounting plate 101, and the first clamping groove 109 is suitable for mounting a step of the ladder 5. That is, the first mounting seat is formed with the first catching groove 109 by providing the first mounting plate 101 and the first fixing plate 102 to fix the switch body 106 to the step 501 of the ladder 5. On the basis, the switch body 106 is fixed on the second side of the first mounting plate 101, and the traction component 4 is suitable for triggering the switch body 106 under the action of external force. The first side of the first mounting board 101 corresponds to the second side of the first mounting board 101, for example, the first side refers to the back side of the first mounting board 101, and the second side refers to the front side of the first mounting board 101.

Of course, the structural form of the first mounting seat is not limited by the drawings as long as the switch body 106 can be fixed to the ladder 5. For example, the first fixing plate 102 in fig. 2 is U-shaped; however, the first fixing plate 102 may be designed to have a flat plate shape, and the first mounting plate 101 is partially recessed to form the first card slot 109. For another example, the first mounting plate 101 may be hung on a step by a hook. The first mounting seat of the above form can fix the switch body 106 to the ladder 5 without any change in the structure of the ladder 5. It is of course also possible to fix the switch body 106 to the ladder 5 by making mounting holes in the ladder 5.

According to an embodiment of the present invention, referring to fig. 3, the switch component 1 further includes a limiting plate 103 and a trigger. The limiting plate 103 is fixed on the second side of the first mounting plate 101, and a limiting hole 1031 is formed in the limiting plate 103 along the extending direction of the ladder stand 5; the trigger is disposed in the limiting hole 1031, connected to the traction member 4, and adapted to move along the limiting hole 1031 under the driving of the traction member 4 to trigger the switch body 106. The lowest position of the trigger can be limited through the arrangement of the limiting hole 1031, so that even if the traction part 4 deforms, the trigger does not move downwards, and the trigger is prevented from moving downwards to falsely trigger the switch body 106 (the trigger moves upwards to trigger the switch body 106, but when the trigger moves downwards to reach a certain stroke, the switch body 106 is also triggered). In fig. 3, the limiting hole 1031 is in the form of an oblong hole, and the bottom of the oblong hole can limit the lowest point of the trigger. In addition, the limiting hole 1031 can play a guiding and limiting role in the trigger. Of course, even if the limiting plate 103 and the triggering member are not provided, the traction member 4 may be directly connected to the switch body 106, and then the switch body 106 may be directly triggered when the traction member 4 is stressed.

According to an embodiment of the invention, referring to fig. 4, the stop collar component 3 includes a second mounting seat and a stop collar body 303. At this time, the collar body 303 may be fixed to the ladder 5 by the second mount. Of course, the stop ring part 3 may not be provided with the second mounting seat, and the stop ring body 303 may be directly fixed to the ladder 5 by welding, bonding, or screwing. The structural form of the retainer ring body 303 is not limited as long as a through hole through which the traction member 4 passes can be formed.

In fig. 4, the second mounting seat includes a second mounting plate 301 and a second fixing plate 302 detachably disposed on a first side of the second mounting plate 301, a second locking groove 304 is formed between the second fixing plate 302 and the second mounting plate, and the second locking groove 304 is adapted to mount a step of the ladder 5. On this basis, the spacing ring body 303 is fixed on the second side of the second mounting plate 301, the first side of the second mounting plate 301 corresponds to the second side of the second mounting plate 301, and the traction component 4 penetrates through the spacing ring body 303. For example, a first side of the second mounting board 301 refers to a rear side of the second mounting board 301, and a second side of the second mounting board 301 refers to a front side of the second mounting board 301.

Of course, the structural form of the second mounting seat is not limited by the drawings as long as the retainer ring body 303 can be fixed to the ladder 5. For example, the second retaining plate 302 is U-shaped in FIG. 4; however, the second fixing plate 302 may be designed to have a flat plate shape, and the second mounting plate 301 is partially recessed to form the first card slot 109. For another example, the second mounting plate 301 may be hung on a step by a hook. The second mounting seat in the above form can fix the limit ring body 303 to the ladder stand 5 without changing the structure of the ladder stand 5. Of course, the stop collar body 303 may also be fixed to the ladder 5 by making mounting holes in the ladder 5.

According to an embodiment of the invention the switching element 1 is fixed to the bottom of the ladder 5 and the traction element 4 is adapted at a first end to trigger the switching element 1 and at a second end to be connected to the top end of the ladder 5. Under this kind of circumstances, traction element 4 distributes in whole cat ladder 5, and then the climbing personnel can all trigger switch part 1 through less trigger force value and less action range (corresponding trigger distance) in the optional position of cat ladder 5 to guarantee high altitude jacking equipment's safety in utilization.

According to the embodiment of the present invention, the opening and closing member 1, the drawing member 4, the spacing ring member 3, and the tension member 2 are disposed corresponding to the end of the step. In fig. 1, the switch component 1, the traction component 4, the spacing ring component 3 and the tensioning component 2 are arranged corresponding to the right end of the step, so that climbing of the ladder stand 5 is not affected. Of course, the opening and closing member 1, the pulling member 4, the stopper ring member 3, and the tension member 2 may be provided corresponding to the left end of the step. Or, under the condition that the step of the ladder 5 is wide enough, the switch component 1, the traction component 4, the spacing ring component 3 and the tension component 2 can be arranged corresponding to the middle part of the step, and only the false triggering of the switch component 1 needs to be avoided.

The high-altitude lifting equipment provided by the embodiment of the invention can be, but is not limited to, a wind power tower in the field of wind power generation.

According to an embodiment of the second aspect of the present invention, there is provided a safety device for a high-altitude lifting apparatus (hereinafter referred to as a safety device), comprising a switch component 1 and a traction component 4.

Further, the step 501 of the ladder stand 5 is fixed with a fastener into the first card slot 109 between the first mounting plate 101 and the first fixing plate 102. The trigger piece is in the form of a trigger bolt 104, and the trigger bolt 104 is fittingly mounted to the limiting hole 1031 through a spacer 107 and a gasket 108. The stopper plate 103 is shaped like a U and is fixed to the first mounting plate 101 by a rivet 105. The initial position of the trigger bolt 104 is the lowest position of the limiting hole 1031, and at this time, the steel wire rope has a pretension force under the action of the tensioning part 2. When the switch body needs to be triggered, only a small force is applied to the steel wire rope, and at the moment, the steel wire rope drives the trigger bolt 104 to move upwards along the limiting hole 1031, and the switch component is triggered.

The spacing ring part 3 includes a second mounting plate 301, a second fixing plate 302, and a spacing ring body 303. The limiting ring body 303 is a U-shaped bolt, that is, a through hole for the traction component 4 is formed between the U-shaped bolt and the second mounting plate 301. Similarly, a second locking groove 304 of the ladder 5 is formed between the second mounting plate 301 and the second fixing plate 302. Further, the step 501 of the ladder stand 5 is fixed between the second mounting plate 301 and the second fixing plate 302 using a fastener.

According to the high-altitude lifting equipment disclosed by the embodiment of the invention, the safety device is high in safety, simple in appearance and small in size, the structural strength of the high-altitude lifting equipment is ensured, the high-altitude lifting equipment is convenient to mount, and the normal use of the ladder stand 5 is not influenced.
