Of course, the other objects to be hoisted may be hoisted on the premise of utilizing the structure and principle of the hoisting device of the present embodiment, and the present embodiment will be described by taking the hoisting partition main body as an example.
On the basis of the scheme, the purpose of three-point hoisting is achieved, but in a practical scene, the situation that the transmission chain is knotted due to the fact that the partition wall main body overturns around the transmission chain at a certain side because the transmission chain at the side is too tight can occur. In order to deal with the problem, the tightening degree of the main transmission chain 6 relative to the auxiliary transmission chain 5 needs to be adjusted, specifically, a clutch 2 is arranged between the hoisting mechanism and the guide mechanism, the clutch 2 mainly realizes the function of clutch transmission between the main hoisting sprocket 11 and the auxiliary hoisting sprocket 12, the clutch 2 comprises a control frame, a linkage shaft 25 and three sets of clutch wheel sets, the clutch wheel sets comprise a first clutch wheel 21 and a second clutch wheel 22 which are coaxially fixed side by side, the coaxial fixing side by side means that the first clutch wheel 21 and the second clutch wheel 22 are distributed in parallel in the same axial direction, and the parameters of the first clutch wheel 21 and the second clutch wheel 22 are approximately the same, and the clutch wheel sets can be replaced by the transmission components through the parallel movement in the axial direction.

The second end 91 comprises a housing 911, a sliding cylinder 912, a first connecting rod and two sets of fasteners, the housing 911 is, for example, a frame-shaped housing, one side of the housing is fixed on the outer side of the auxiliary outer cylinder 81 of the auxiliary guide frame 8, the other side of the housing is provided with a semispherical groove 913, and the first universal ball 914 is rotatably fitted in the semispherical groove 913, so that the universal connection between the universal joint 92 and the second end 91 is realized.
In order to make the universal joint 9 assume a stable locked state after rotation, the sliding cylinder 912 is slidably disposed in the housing 911, in particular, slides along a vertical plane relative to the axial direction of the strut. A first sliding ball 915 is arranged in an inner hole of the sliding cylinder 912, the first sliding ball 915 can slide in the inner hole of the sliding cylinder 912, one end of the connecting rod is fixedly connected with the first sliding ball 915, and the other end of the connecting rod extends into the hemispherical groove 913 to be fixedly connected with the first universal ball 914, so that the first universal ball 914 and the first sliding ball 915 can be linked, and after the first universal ball 914 rotates, the first sliding ball 915 can synchronously swing, so that the sliding cylinder 912 is pushed to slide in the corresponding direction in the housing 911, and the whole process is also reversible, that is, the sliding cylinder 912 can slide to drive the first universal ball 914 to rotate.
The stability of the sliding tube 912 is then achieved to stabilize the first ball 914 and the entire gimbal 92. Specifically, two sets of fasteners are respectively located two sides of the housing 911, the fasteners include a driving portion 917 and an attaching portion 916, the attaching portion 916 extends into the housing 911 and is attached to or away from the sliding barrel 912 under the action of the driving portion 917, that is, the driving portion 917 inputs power to drive the attaching portion 916 to reciprocate, and the sliding barrel 912 is fixed by the attaching portions 916 at two sides. For example, the fitting portion 916 is in the form of a screw rod matching with a screw seat, the driving portion 917 is in the form of an electric wrench, and the screw seat is fixed outside the auxiliary guide frame 8 and can move along with the auxiliary guide frame 8, so that the problem of movement interference does not occur. The lead screw is connected with the screw seat inner hole in a threaded manner, the end part of the lead screw is rotatably connected with a tile body, the inner side of the tile body can be attached to the outer side of the sliding barrel 912, for example, an arc-shaped attaching form is adopted, so that the sliding barrel 912 can be firmly clamped, and finally, under the action of an electric wrench, the lead screw moves forwards or backwards while driving the tile body to be attached to or away from the sliding barrel 912, and the purpose that the sliding barrel 912 can slide in the shell 911 can be locked or unlocked is achieved.
Through above technical scheme to the position of slide cartridge 912 is adjusted to the mode of accessible adjustment fastener, with the adjustment of realizing first universal ball 914, finally allows vice leading truck 8 can be relative main leading truck 7 free rotation in certain extent, not only can not receive the problem of motion interference, and vice leading truck 8 swings the cooperation that arbitrary position can both be through two sets of fasteners and realize firm locking moreover, and it is more convenient and stable for traditional universal locking.
On the basis of the above scheme, considering that the movement range of the secondary guide frame 8 is limited by the maximum movement range of the first universal ball 914 (due to interference between the position of the strut and the hemispherical groove 913), the contact between the first universal ball 914 and the hemispherical groove 913 is further reduced, and the connection stability is also reduced, and in order to increase the further movement range of the secondary guide frame 8 under the limitation, the main guide frame 7 and the first end 93 are rotatably connected and can swing vertically and horizontally relatively, so that the universal joint 92 and the secondary guide frame 8 integrally move at a larger angle without horizontal displacement of the main guide frame 7. That is, in this embodiment, the first end 93 and the second end 91 have the same structure, and the strut is rotatably connected to the hemispherical groove 913 of the second end 91 and the hemispherical groove of the first end 93 through the first universal ball 914, so as to achieve the purpose of increasing the range of motion of the sub-guide 8.
Of course, in some embodiments, the distance between the main guide frame 7 and the auxiliary guide frame 8 may also be adjusted to adapt to a wider adjustment space, specifically, the supporting rod includes a first section 923 and a second section 921 of a telescopic connection, the end portions of the first section 923 and the second section 921 are provided with a first universal ball 914, for example, the first section 923 and the second section 921 adopt screws, the telescopic connection is realized by adopting a nut sleeve 922, and the telescopic connection is realized by adjusting the nut sleeve 922 to rotate, so that the first section 923 and the second section 921 with opposite rotation directions are close to or far away from each other to realize the telescopic connection.
In addition to the above solutions, considering that there are many ways in which the directions of the main guide frame 7 and the sub guide frame 8 can be adjusted relatively, for example, the slide cylinders 912 of the first ends 93 on both sides of the main guide frame 7 are locked so that the corresponding first universal balls 914 cannot rotate, and at this time, the sub guide frame 8 can only rotate with the first universal balls 914 of the second ends 91, which is suitable for the case where the main hoisting position is not changed but only the sub hoisting position needs to be adjusted slightly. For example, when the auxiliary guide frame 8 is adjusted, the slide cylinder 912 in the second end 91 of the auxiliary guide frame 8 may be locked to adjust the adjacent first end 93 as the rotation center, and this scenario is suitable for a case where the main hoisting position is not changed and the auxiliary hoisting position needs to be adjusted relatively largely.
For example, the slide cylinder 912 in the second end 91 of the auxiliary guide frame 8 and the slide cylinders 912 in the first ends 93 at both sides of the main guide frame 7 can be locked at one side and can rotate around the first universal ball 914 in the second end 91 of the auxiliary guide frame 8 at the other side, so that the scene is suitable for the situation that the auxiliary hoisting position at one side is tight and the main hoisting position and the other auxiliary hoisting position need to be adjusted, so as to realize the purpose of overturning the partition main body. In the third scenario, the transmission chain that is tight needs to be loosened, and the other two positions of the transmission chain keep being clamped, where clamping means clamping the transmission chain on the slack side rather than over-clamping.
Specifically, a second sliding ball 918 is disposed in an inner hole of the sliding barrel 912, the second sliding ball 918 is connected to another second universal ball 919 through another connecting rod, the second universal ball 919 is rotatably fitted (for example, by using a manner of fitting the first universal ball 914 with the hemispherical groove 913) on an inner side wall of the corresponding guide frame (the main guide frame 7 or the auxiliary guide frame 8), and a side of the second universal ball 919 away from the inner wall of the corresponding guide frame is provided with a first guide rubber 910. The inner wall of the side of the auxiliary guide frame 8, which is not provided with the second universal ball 919, is provided with second guide rubber, and a conveying channel corresponding to a transmission chain is formed between the first guide rubber 910 and the second guide rubber. That is, it means that two first guide rubbers 910 in the main guide frame 7 form a conveying path of the main drive chain 6, and a conveying path of the sub drive chain 5 is formed between the first guide rubbers 910 and the second guide rubbers of the sub guide frame 8.
The first guide rubber 910 and the second guide rubber are used for guiding and damping the corresponding transmission chain to maintain the stability of the transmission chain in operation. In addition, by using the principle that the first universal ball 914 and the second universal ball 919 move in a mirror image manner, when one of the first universal ball 914 and the second universal ball 919 rotates, in the third illustrated scenario, the second guiding frame 8 on the non-rotating side drives the second universal ball 919 to rotate due to the first universal ball 914, so that the first guiding rubber 910 and the second guiding rubber move relative to each other, and a larger gap is formed, especially in the embodiment where the middle position between the first guiding rubber 910 and the second guiding rubber is relatively convex, the secondary transmission chain 5 in the secondary guiding frame 8 starts to be loose, that is, the corresponding transmission channel is open, and the transmission channels of the primary transmission chain 6 and the other secondary transmission chain 5 are kept unchanged, that is, relatively clamped, so as to adapt to the purpose of stable overturning of the partition wall body in the scenario.
