Detailed Description

The invention is further described with reference to the following figures and detailed description.

As shown in fig. 1 to 4, the lambdoidal machine hoisting device comprises a first crane 1 and a second crane 2, wherein the first crane 1 is arranged above a motor span 3 correspondingly, the second crane 2 is arranged above a rolling mill span 4 correspondingly, a separation region which is separated by a factory building upright post 5 and a plate beam structure 6 arranged at the upper end of the factory building upright post 5 is arranged between the motor span 3 and the rolling mill span 4, an installation station of a human-machine 7 is arranged in the separation region, the lambdoidal machine hoisting device further comprises a balance hoisting beam 8 and a transfer platform 9, at least two groups of crane hoisting points 10 are arranged on the balance hoisting beam 8 along the length direction of the balance hoisting beam, and the first crane 1 and the second crane 2 can be respectively hoisted and connected with the corresponding crane hoisting points 10 through corresponding hoisting ropes 12; a herringbone machine hoisting point 11 is arranged in the middle of the balance hoisting beam 8, and the herringbone machine hoisting point 11 can be connected with the herringbone machine 7 in a hoisting mode through a corresponding hoisting rope 12; the balance hoisting beam 8 crosses the separation region in a crossing manner, one end of the balance hoisting beam 8 penetrating through the motor span 3 is connected with the first crane 1 in a hoisting manner through a crane hoisting point 10 on the balance hoisting beam, and one end of the balance hoisting beam 8 penetrating through the rolling mill span 4 is connected with the second crane 2 in a hoisting manner through the crane hoisting point 10 on the balance hoisting beam; the transfer platform 9 is arranged on one side of the motor span 3 or one side of the rolling mill span 4, the transfer platform 9 corresponds to an installation station of the herringbone machine 7, and the herringbone machine 7 can be lifted and transferred between the installation station of the herringbone machine 7 and the transfer platform 9 through the first crane 1 and the second crane 2.

The motor span 3 is a plant area for mounting a motor 13 of the universal mill; the mill bay is a factory area for installing a mill 14 of the universal mill; the herringbone machine 7 is a transmission mechanism for driving and connecting the motor 13 and the rolling mill 14, and is actually a speed reducer. In addition, corresponding traveling crane cranes are usually arranged in the corresponding areas of the motor span 3 and the rolling mill span 4 to hoist corresponding equipment; correspondingly, the first crane 1 and the second crane 2 are crane devices respectively arranged in the motor bay 3 and the rolling mill bay 4, and belong to crane devices which are already existed originally. However, as shown in fig. 1, due to the limitation of the building layout, the herringbone machine 7 is installed below the plate beam structure 6 between the motor bay 3 and the rolling mill bay 4 of the plant, so that the existing crane cannot directly hoist the herringbone machine 7 by itself, i.e., cannot directly hoist the herringbone machine 7 by using the first crane 1 or the second crane 2 alone.

The balance hoisting beam 8 is respectively connected with the first crane 1 and the second crane 2 through corresponding crane hoisting points 10 on two ends of the balance hoisting beam, and then is directly connected with the herringbone machine 7 through the herringbone machine hoisting points 11 on the balance hoisting beam 8, so that the herringbone machine 7 can be indirectly hoisted by using two cranes, and the problem that the herringbone machine 7 cannot be directly hoisted by a single crane is solved. And then the herringbone machine 7 can be transferred to the transfer platform 9 from the separation area between the motor span 3 and the rolling mill span 4 or reversely hoisted by synchronously controlling the hoisting and moving of the two cranes. Therefore, after the hoisting device is adopted, the hoisting operation is very convenient, and the hoisting device does not need to be additionally provided with equipment such as a winch and the like for auxiliary hoisting, so that the time required by the disassembly and assembly of the character machine 7 can be effectively shortened, the effective operation time of the universal rolling mill is improved, and the production efficiency is improved.

More specifically, referring to the attached drawings, the balance hoisting beam 8 can be specifically arranged as a box beam; the beam structure is a hollow box body with a rectangular cross section formed by welding and connecting corresponding steel plates on all sides, and both ends of the beam structure can be sealed after being welded with the steel plates. Of course, without loss of generality, the balance hoisting beam 8 should meet the weight load requirement of the herringbone machine 7 to be hoisted, for example, if the weight of the herringbone machine 7 to be hoisted is 22.2T, the cross-sectional dimension of the box-shaped beam can be designed to be 800mm x 400mm, the length of the box-shaped beam is 10000mm, the box-shaped beam is made by welding steel plates with the thickness of 20mm, and the two ends of the box-shaped beam are welded and sealed by using the steel plates with the same thickness of 20mm as sealing plates; the suspension noses are then welded in the respective positions as crane suspension points 10 and as point crane suspension points 11.

In addition, the crane lifting points 10 of the present invention are used for lifting connection with corresponding cranes, and in order to meet the requirements of different partition sizes, the distance between the first crane 1 and the second crane 2 with different distances, etc., at least two sets of crane lifting points are respectively provided for the first crane 1 and the second crane 2. As shown in fig. 2, the crane lifting points 10 may be arranged such that the middle section of the balance lifting beam 8 is arranged in mirror symmetry, and four sets of crane lifting points 10 are arranged on any side of the middle section of the balance lifting beam 8, and each set of crane lifting points 10 are arranged at intervals along the length direction of the balance lifting beam 8. In this way, according to the actual situation, one group of hoisting points 10 with the best position is selected from at least two groups of hoisting points 10 of the crane positioned on one side of the middle section of the balanced hoisting beam 8 and is connected with the corresponding crane in a hoisting way through the hoisting rope 12, and the requirement of subsequent hoisting movement distance for the character machine 7 is met; wherein the set of hoisting points 10, which is best positioned, should be selected such that the respective hoisting rope 12 is in a vertical position or closest to a vertical position after hoisting connection.

In addition, for each group of crane lifting points 10, the crane lifting points can be specifically arranged to be composed of two convex mirror-image-symmetric lifting noses arranged on the front side and the rear side of the balance lifting beam 8, as shown in fig. 3. Wherein the front and rear sides of the counterbalancing hoist beam 8 are with respect to the orientation shown in figure 2.

In addition, two lifting lugs or a plurality of lifting lugs are usually arranged on the herringbone machine 7, so that two groups of herringbone machine lifting points 11 or a plurality of groups with the same number as the lifting lugs on the herringbone machine 7 can be correspondingly arranged in the invention so as to be matched with the lifting lugs on the herringbone machine 7. Referring to fig. 2 and 3, two sets of the herringbone machine hanging points 11 are specifically arranged, and the two sets of the herringbone machine hanging points 11 are arranged in a mirror symmetry mode on the middle section of the balance hoisting beam 8. Correspondingly, each group of the herringbone machine lifting points 11 can also be formed by two convex mirror-image-symmetric lifting noses at the front side and the rear side of the balance lifting beam 8. Wherein the front and rear sides of the counterbalancing hoist beam 8 are with respect to the orientation shown in figure 2.

In addition, the transfer platform 9 is used for temporarily bearing the herringbone machine 7 in the dismounting process, and can temporarily bear the dismounted herringbone machine 7 in the old herringbone machine 7 dismounting process so as to be convenient for transferring by adopting a single crane in the subsequent process; and in the process of installing the new propeller strut 7, the propeller strut can be used for firstly bearing the new propeller strut so as to be conveniently and smoothly connected with the balance hoisting beam 8 and carry out subsequent hoisting transfer. Without loss of generality, the transfer platform 9 should meet basic requirements such as the required bearing capacity requirement, rigidity requirement, flatness requirement and the like so as to smoothly and stably bear the transfer herringbone machine 7. The specific transfer platform 9 can be formed by splicing I-shaped steel beams and is reasonably arranged according to the size required by the actual placement of the Chinese character machine 7; if necessary, corresponding oblique supporting beams can be arranged for supporting so as to improve the structural rigidity of the transfer platform 9; reference is made in particular to fig. 4.

In addition, the herringbone machine hoisting method provided by the invention is actually the herringbone machine hoisting method after the herringbone machine hoisting device provided by the invention is adopted, and specifically comprises an old herringbone machine 7 dismantling and hoisting method and a new herringbone machine 7 installing and hoisting method according to the dismantling or installing of the herringbone machine 7.

The dismantling method of the old herringbone machine 7 comprises the following steps: loosening foundation bolts of an old herringbone machine 7, simultaneously hoisting and moving a balance hoisting beam 8 to be right above the old herringbone machine 7 by a first crane 1 and a second crane 2, then hoisting and connecting a herringbone machine hoisting point 11 on the balance hoisting beam 8 with a corresponding lifting lug on the old herringbone machine 7 by using a hoisting rope 12, simultaneously hoisting and transferring the old herringbone machine 7 onto a transfer platform 9 by the first crane 1 and the second crane 2, and then loosening a hoisting steel rope between the old herringbone machine 7 and the balance hoisting beam 8. For the hoisting process of the character machine 7, theoretically, a single crane can be adopted for directly hoisting; for example, as shown in fig. 1, when the transfer platform 9 is located on the mill bay 4, the second crane 2 above the mill bay 4 can be directly used for subsequent lifting.

The new installing and hoisting method of the propeller strut 7 comprises the following steps: the balance hoisting beam 8 is hoisted and moved to be right above a new herringbone machine 7 placed on a transfer platform 9 through a first crane 1 and a second crane 2 simultaneously, then a herringbone machine hoisting point 11 on the balance hoisting beam 8 is hoisted and connected with a corresponding lifting lug on the new herringbone machine 7 through a hoisting steel rope 12, then the first crane 1 and the second crane 2 hoist simultaneously and transfer the new herringbone machine 7 to an installation station of a man-machine 7 and place the new herringbone machine in alignment, then the hoisting steel rope between the new herringbone machine 7 and the balance hoisting beam 8 is loosened, and finally a foundation bolt of the man-machine 7 is installed. Of course, theoretically, the character machine 7 can be directly hoisted in advance and placed on the transfer platform 9 by adopting a single crane; for example, as shown in fig. 1, when the transfer platform 9 is located at the rolling mill span 4, the second crane 2 directly above the rolling mill span 4 can be used to hoist the character 7 onto the transfer platform 9 for temporary placement, so as to facilitate subsequent connection with the balance hoisting beam 8. More specifically, the height of the installation plane of the transfer platform 9 corresponding to the installation station of the herringbone machine 7 should be approximately flush, so as to facilitate smooth hoisting and transferring of the herringbone machine 7.

In addition, more specifically, during the actual hoisting process, the first crane 1 and the second crane 2 should be synchronously controlled to be hoisted and lowered so as to ensure a stable hoisting herringbone 7; and simultaneously, the movement of the two along the length of the balance hoisting beam 8 should be synchronously controlled so as to ensure the stable movement of the herringbone machine 7. More specifically, in the process of hoisting the herringbone machine 7 by the first crane 1 and the second crane 2 and transferring, the hoisting height of the herringbone machine 7 is only 200 and 400 mm; of course, it is required that the transfer platform 9 is substantially flush with the mounting plane corresponding to the mounting station of the herringbone machine 7 to avoid interference.
