The terms "first," "second," and the like in the description and claims of this application or in the above-described drawings are used for distinguishing between different objects and not for describing a particular order.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

As shown in fig. 1 and 2, a track system 100 according to a preferred embodiment of the present invention includes a mounting frame 07, a rotating frame 03, a positioning wheel 02, a guide rail 01, a fixing base 08, an apparatus body 13, a positioning sensing assembly, and a lifting assembly 04. The limiting device comprises a mounting frame 07, a rotating frame 03, a positioning wheel 02, a fixed seat 08, a lifting assembly 04, an in-place sensing assembly and a positioning sensing assembly, and the track equipment comprises a limiting device and an equipment body 13.

The fixed connection between the components can adopt welding, bolt connection and other connection modes.

The guide 01 has a guide plane for receiving the mobile device.

The mounting frame 07 is located above the guide rail 01 and can move parallel to the guide rail 01. The mounting frame 07 can move along a specific path on the guide rail 01, and the guide rail 01 can have a guiding function. The power for driving the mounting frame 07 to move may be manual power or traction force provided by the device body 13. The mounting frame 07 can also slide along the guide rail 01 under inertia or self-gravity. Preferably, the mounting frame 07 is connected with the equipment body 13, and the equipment body 13 is used for dragging the mounting frame 07 to move on the guide rail 01.

The rotating frame 03 is hinged to the mounting frame 07, and in other embodiments, the rotating frame 03 may be mounted on the fixing base 08. The positioning wheel 02 is rotatably arranged at one end, far away from the mounting frame 07, of the rotating frame 03, the positioning wheel 02 is abutted against the guide rail 01, and the guide rail 01 is provided with a positioning groove 101 for accommodating the positioning wheel 02. The positioning groove 101 may be circular or square. One end of the rotating frame 03 is hinged with the positioning wheel 02, and the other end of the rotating frame is hinged with the mounting frame 07 through a connecting shaft 10, so that the rotating frame 03 and the mounting frame 07 form a revolute pair mechanism. The positioning wheel 02 keeps abutting against the guide rail 01, and when the mounting frame 07 reaches a certain specific position, the positioning wheel 02 falls into the positioning groove 101. The urging force for holding the positioning wheel 02 in contact with the guide rail 01 may be a driving force provided by another actuator or an elastic force provided by a spring. Preferably, the positioning wheel 02 is kept in abutment with the guide rail 01 and enters the positioning slot 101 by the weight of the turret 03 or the positioning wheel 02. This reduces the dependence on other components, and mechanically limits the rail system 100, thereby contributing to improvement in the reliability of limiting the rail system 100.

The in-place switch 06 may be a travel switch, a microswitch, a proximity switch or a photoelectric switch. The in-place switch 06 may be any type of limit switch. In some examples, the in-place switch 06 may have an exposed spring, and in a normal state, the in-place switch 06 is in an off state, and when the positioning wheel 02 enters the positioning groove 101, the rotating frame 03 rotates, and the in-place sensing piece 05 touches the spring of the in-place switch 06, so that the in-place switch 06 is turned on to send a signal. In other examples, the position switch 06 may be a non-contact photoelectric switch, and when the positioning wheel 02 enters the positioning groove 101, the rotating frame 03 rotates, and the position sensing piece 05 enters a position for triggering the photoelectric switch, so that the photoelectric switch sends a signal.

In other embodiments, the detection function may be implemented by directly detecting the state change of the rotating frame 03 without providing the position sensing piece 05.

When the mounting rack 07 moves to a specific position, the positioning wheel 02 enters the positioning groove 101 and simultaneously drives the rotating frame 03 to rotate, so that the in-place sensing piece 05 triggers the in-place switch 06, the position of the mounting rack 07 can be detected through signals of the in-place switch 06, and the position detection function with high reliability is realized.

The positioning wheel 02 is located in the positioning groove 101, and if the mounting frame 07 needs to move continuously, the push rod of the controllable cylinder extends out to jack the rotating frame 03 up so that the positioning wheel 02 leaves the positioning groove 101. In the moving process of the mounting frame 07, the push rod of the air cylinder is retracted to be separated from the rotating frame 03, and the positioning wheel 02 is kept in contact with the guide rail 01 under the action of the gravity of the rotating frame 03 or the positioning wheel 02. In other examples, the lifting assembly 04 may not be needed, the positioning groove 101 may be provided with a slope, and the positioning wheel 02 may leave the positioning groove 101 under the traction of the mounting frame 07.

If the mounting block 07 needs to move continuously, the lifting assembly 04 can be controlled to lift the rotating frame 03, and the positioning wheel 02 passes through the flange 111 and leaves the positioning groove 101, so that the mounting block 07 can move continuously.

The positioning sensing assembly and the in-place sensing assembly may employ the same sensing element. Preferably, the positioning sensing assembly employs a non-contact sensing element. The positioning detection switch 09 may be a photoelectric switch, and the positioning sensing block 12 may be a positioning sensing piece 05 for triggering the photoelectric switch. The position detection switch 09 may also be a correlation switch. The positioning detection switch 09 may also be a hall sensor, and the positioning sensing block 12 may be a metal member or a magnetic member for triggering the hall sensor. The positioning sensing assembly and the in-place sensing assembly can play a role of double-sensing interlocking, and the reliability and the safety of position detection of the track system 100 can be improved.

Preferably, the guide rail 01 is provided with a plurality of positioning grooves 101, and the plurality of positioning grooves 101 are spaced apart along the moving direction of the mounting frame 07. This enables the position of the mount block 07 to be detected at a plurality of position points.

Preferably, the track system 100 further comprises a positioning sleeve 11, the positioning sleeve 11 is embedded in the guide rail 01, and the positioning slot 101 is disposed on the positioning sleeve 11. Positioning wheel 02 contacts with constant head tank 101 many times, damages constant head tank 101 easily, locates positioning sleeve 11 with constant head tank 101, and positioning sleeve 11 buries in guide rail 01, if constant head tank 101 damages, then change positioning sleeve 11 can, be favorable to maintaining operation and reduce cost. The positioning sleeve 11 may have a square shape, and the positioning groove 101 therein may also have a square shape. The flange 111 is formed on the cylindrical wall of the positioning sleeve 11 and projects toward the center of the positioning sleeve 11. The positioning sleeve 11 may be made of a hard material such as metal like alloy or ceramics.

The guide rail 01 is parallel to the running track of the equipment body 13 and is fixed on the walking ground through bolt connection, and a positioning sleeve 11 and an in-place positioning sensing block 12 of a positioning detection switch 09 are arranged at each positioning point on the guide rail 01. This enables fixed-point detection of whether the mount frame 07 and the apparatus body 13 are in place.

The mounting frame 07, the fixing seat 08 and the positioning wheel 02 rotating frame 03 are formed by welding plates and profiles, and are simple to manufacture, firm and reliable. The mounting frame 07 is a mounting framework of the entire rail system 100 and is also a transition piece connected to the apparatus body 13. The positioning wheel 02 and the rotating frame 03 are respectively matched with the fixed frame through connecting shafts to form a revolute pair mechanism. Under the action of the lifting cylinder and gravity, the positioning wheel 02 and the rotating frame 03 can flexibly rotate relative to the fixed frame; the guide rail 01 is provided with a positioning sleeve 11 structure as a positioning point, a positioning wheel 02 runs on the guide rail 01 under the traction of external running equipment 13, the positioning wheel can flexibly enter the positioning sleeve 11 under the action of gravity (mechanical interlocking is formed, interlocking failure caused by failure of an electrical induction device is prevented), stable mechanical limiting is provided for the equipment body 13, meanwhile, the in-place switch 06 and the positioning detection switch 09 are triggered, a feedback signal can be sent to a control system of the equipment body 13, the running and stopping of the equipment body 13 can be accurately controlled, and the position of the equipment body is detected, so that the track system 100 can be widely applied to the field of amusement facilities and other working fields.

In this embodiment, when the track system 100 is located at any one of the start point, the end point or the middle positioning point, the rotating frame 03 rotates relative to the mounting frame 07 to enable the positioning wheel 02 to flexibly enter the positioning groove 101 to provide a mechanical limit for the apparatus body 13. The in-place sensing component, the in-place switch 06 in the positioning sensing component, and the positioning detection switch 09 in the positioning sensing component are triggered to send out a signal of stopping the operation instruction to the device body 13. The lifting assembly 04 is used for disengaging the positioning wheel 02 from the positioning groove 101 so that the device body 13 continues to work. The in-place switch 06 can provide a start and stop control signal for the apparatus body 13, the positioning detection switch 09 can provide a stop and position judgment signal for the apparatus body 13, and any one of the in-place switch 06 and the positioning detection switch 09 can send a stop operation instruction signal to the apparatus body 13.
