Specifically, the hoisting mechanism comprises a driving shaft, a main hoisting chain wheel 11 and two groups of auxiliary hoisting chain wheels 12 coaxially arranged with the main hoisting chain wheel 11, wherein the main hoisting chain wheel 11 is fixedly sleeved on the driving shaft, and the auxiliary hoisting chain wheels 12 are rotatably sleeved on the driving shaft (through bearings), so that the driving shaft is utilized to realize the form of coaxial distribution of the main hoisting chain wheel 11 and the two groups of auxiliary hoisting chain wheels 12, namely, the end surfaces of the main hoisting chain wheel 11 and the two groups of auxiliary hoisting chain wheels 12 are mutually parallel. The servo motor 13 is arranged at one end of the driving shaft, and can control the driving shaft to rotate forward or backward, so that the main winch chain wheel 11 is driven to rotate forward or backward, and the auxiliary winch chain wheel 12 is in a slipping state and does not rotate along with the rotation of the driving shaft at the moment, so that the clutch transmission connection foundation is provided.
The guiding mechanism comprises a main guiding frame 7 and auxiliary guiding frames 8 which are respectively arranged on two sides of the main guiding frame 7, and universal connecting pieces 9 are respectively arranged between the two groups of auxiliary guiding frames 8 and the main guiding frame 7, so that the auxiliary guiding frames 8 can change directions relative to the main guiding frame 7 in the adjusting directions of the universal connecting pieces 9, and the purpose of universal adjustment of the auxiliary guiding frames 8 is achieved. An auxiliary transmission chain 5 is arranged between the single-group auxiliary guide frame 8 and the single-group auxiliary winding chain wheel 12, a main transmission chain 6 is arranged between the main guide frame 7 and the main winding chain wheel 11, namely an auxiliary winding transmission line is formed between the group of auxiliary winding chain wheels 12 and the group of auxiliary transmission chain 5 and the group of auxiliary guide frames 8, an active winding transmission line is formed among the main winding chain wheel 11, the main transmission chain 6 and the main guide frame 7, and finally the three winding transmission lines taking the three winding assemblies 1 as main bodies are formed, and the adjustment and change of the lifting position are realized on the premise of adjusting the direction of the auxiliary guide frame 8, so that the auxiliary winding transmission line is suitable for the lifting operation of partition wall main bodies in more scenes. Of course, the other objects to be hoisted may be hoisted on the premise of utilizing the constitution and principle of the hoisting device of the embodiment, and the hoisting partition body is taken as an example for explanation of the embodiment.
On the basis of the scheme, although the purpose of three-point lifting is achieved, in a practical scene, the situation that the partition wall main body overturns around the side transmission chain because the transmission chain on the side is too tight, and the transmission chain is knotted can occur. To cope with this problem, it is necessary to adjust the tightening degree of the main drive chain 6 relative to the sub drive chain 5, specifically, a clutch 2 is disposed between the winding mechanism and the guiding mechanism, the clutch 2 mainly realizes the clutch transmission function between the main winding sprocket 11 and the sub winding sprocket 12, the clutch 2 includes a control frame, a linkage shaft 25, and three sets of clutch pulley groups, the clutch pulley groups include a first clutch wheel 21 and a second clutch wheel 22 coaxially fixed side by side, where the coaxial fixed side by side means that the first clutch wheel 21 and the second clutch wheel 22 are distributed parallel in the same axial direction, the parameters of the first clutch wheel 21 and the second clutch wheel 22 are substantially the same, and the first clutch wheel 21 and the second clutch wheel 22 can be replaced by parallel movement along the axial direction to become a transmission member.
The first clutch wheels 21 are rotatably sleeved on the linkage shaft 25, the second clutch wheels 22 are fixedly sleeved on the linkage shaft 25, and the control frame is in transmission connection with the linkage shaft 25 so as to switch the synchronous transmission connection of the three first clutch wheels 21 and the main winch chain wheel 11 and the two groups of auxiliary winch chain wheels 12, or the synchronous transmission connection of the three second clutch wheels 22 and the main winch chain wheel 11 and the two groups of auxiliary winch chain wheels 12. That is, three groups of clutch pulley groups are respectively arranged on three winding transmission lines, one of the first clutch pulley 21 and the second clutch pulley 22 in the clutch pulley groups is put into the three winding transmission lines by the action of a control frame, when the first clutch pulley 21 is put into the three winding transmission lines, only the first clutch pulley 21 matched with the main winding chain wheel 11 in the three first clutch pulleys 21 is in a rotating state, at the moment, the auxiliary winding chain wheel 12 is in a 'separated' state, the servo motor 13 only can drive the main transmission chain 6 to lift or descend, so that the adjustment of the tightening degree of the auxiliary transmission chain 5 is achieved, especially when the auxiliary transmission chain 5 is tightened at the side, the main transmission chain 6 continuously rises and tightens, the auxiliary transmission chain 5 begins to loose, and the possibility of overturning the partition main body is reduced under the condition that the main transmission chain 6 pulls the partition body center of gravity in the vertical component direction; when the second clutch wheels 22 enter three winding transmission lines, on the premise that the main winding chain wheel 11 rotates, the second clutch wheels 22 matched with the main winding chain wheel rotate and drive the linkage shaft 25 to rotate, so that the other two second clutch wheels 22 drive the two groups of auxiliary winding chain wheels 12 to synchronously drive, namely in a 'closed' state, and finally the aim of synchronously lifting or descending the main transmission chain 6 and the auxiliary transmission chain 5 is fulfilled, so that the partition wall main body is stably lifted.
Through the above technical scheme, three-point lifting is realized on the one hand, especially this three-point lifting is the condition that the triangle was arranged, can promote the stability that partition wall main part lifted by crane greatly, reduce the possibility of rocking, simultaneously because the high free regulation function of vice leading truck 8 can adapt to the partition wall main part of most specifications and lift by crane here, thereby regard the component edge point of the vertical direction of partition wall main part focus position as main lifting position, the horizontal edge of focus both sides is vice lifting position, has guaranteed the stability requirement of lifting operation greatly. On the other hand, the phenomenon that the partition wall main body overturns when the auxiliary transmission chain 5 on one side is too tight caused by hoisting in the hoisting process can be regulated according to real-time working conditions by controlling the clutch of the main hoisting chain wheel 11 and the two groups of auxiliary hoisting chain wheels 12, so that the stability of the partition wall main body in hoisting operation is further improved.
In some embodiments, only one winding chain wheel is used as a power reversing component of a winding transmission line, the power of the winding chain wheel and the friction force between a chain and the chain wheel are compared, and in order to increase the efficiency of chain transmission on the premise of stable lifting conditions, auxiliary driving wheels similar to the winding chain wheel can be arranged, so that the friction force between the chain and the chain wheel is increased by increasing the contact area, the effective transmission rate of the power of the chain wheel is improved, and the aim of improving the transmission rate of the chain is fulfilled. Specifically, the hoisting mechanism further comprises a gear shifting assembly 3, the gear shifting assembly 3 comprises a transmission shaft and three groups of gear shifting wheels 31 rotatably sleeved on the transmission shaft, the three groups of gear shifting wheels 31 are respectively positioned on one side of the transmission directions of the main hoisting chain wheel 11 and the two groups of auxiliary hoisting chain wheels 12 to form three groups of chain wheel groups, namely, the three groups of gear shifting wheels 31 are combined into three groups of hoisting transmission lines, and one group of main hoisting chain wheels 11 (auxiliary hoisting chain wheels 12), one group of clutch wheel groups and one group of gear shifting wheels 31 form one group of chain wheel groups. Wherein, three sets of gear shifting wheels 31 are respectively connected with the main transmission chain 6 and the two auxiliary transmission chains 5 in a transmission way, thereby achieving the purpose that a winch chain wheel and a gear shifting wheel 31 drive a transmission chain, and the mode of increasing the contact area and increasing the friction force (avoiding the ineffective transmission of skidding) makes the power output of the winch chain wheel more effective, so as to achieve the purpose of realizing the larger transmission speed of the transmission chain. The first clutch wheel 21 or the second clutch wheel 22 in the clutch wheel group is driven to shift the gear wheel 31 between the winding chain wheels when working, thereby achieving the purpose of synchronous clutch connection.
On the basis of the scheme, considering that when the first clutch wheel 21 and the second clutch wheel 22 are directly replaced between the winch chain wheel and the gear shifting wheel 31, a space for improving the replacement safety exists, particularly in the scene of precision matching, the abrasion is increased and even the safety risk of mismatching occurs when parts are hard to splice, so as to solve the problems. In this embodiment, the control frame includes a telescopic controller 23 and a steering controller 24, where the telescopic controller 23 is in transmission connection with a linkage shaft 25, so that three first clutch wheels 21 are respectively in transmission connection with three sets of sprocket sets, or three second clutch wheels 22 are respectively in transmission connection with three sets of sprocket sets; that is, the expansion and contraction direction of the expansion and contraction controller 23 is the same as the axial direction of the linkage shaft 25, and the linkage shaft 25 can be driven to reciprocate by the expansion and contraction controller 23, so that the positions of the first clutch wheel 21 and the second clutch wheel 22 are replaced with each other.

In order to allow the universal joint 9 to assume a stable locked state after rotation, the slide 912 is slidably arranged in the housing 911, in particular along a vertical plane axially opposite the strut. The first sliding ball 915 is disposed in the inner hole of the sliding barrel 912, the first sliding ball 915 can slide in the inner hole of the sliding barrel 912, one end of the connecting rod is fixedly connected with the first sliding ball 915, 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, after the first universal ball 914 rotates, the first sliding ball 915 can swing synchronously, thereby pushing the sliding barrel 912 to slide in the corresponding direction in the housing 911, and the whole process is reversible, i.e. the sliding of the sliding barrel 912 can drive the first universal ball 914 to rotate.
Then, the slide 912 is stabilized to stabilize the first ball 914 and the entire joint 92. Specifically, the two sets of fasteners are respectively located at 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 slide 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 slide 912 is fixed (by the attaching portions 916 at two sides). For example, the attaching portion 916 is in a form of a screw rod and a screw seat, the driving portion 917 is in a form of an electric wrench, and the screw seat is fixed on the outer side of the auxiliary guide frame 8 and can move along with the auxiliary guide frame 8, so that the problem of movement interference cannot occur. The lead screw is connected with the inner hole of the screw seat 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 tightly attached to the outer side of the sliding cylinder 912, for example, an arc attaching mode is adopted, the clamping of the sliding cylinder 912 can be ensured to be more stable, and finally under the action of an electric wrench, the lead screw is enabled to move forwards or backwards and simultaneously drive the tile body to be tightly attached to or away from the sliding cylinder 912, so that the purpose that the sliding cylinder 912 can slide in the shell 911 is achieved.
Through the above technical scheme to the position of slide 912 is adjusted to the mode of accessible adjustment fastener to realize the adjustment of first universal ball 914, finally allow vice leading truck 8 can be relative main leading truck 7 free rotation in a certain limit, can not receive the problem that the motion interfered, and vice leading truck 8 swings to arbitrary position all can realize firm locking through the cooperation of two sets of fasteners moreover, and is more convenient and stable for traditional universal locking.
On the basis of the above scheme, considering that the movement range of the auxiliary guide frame 8 is limited by the maximum movement range of the first universal ball 914 (the interference reason between the position of the supporting rod and the hemispherical groove 913 is present), the contact between the first universal ball 914 and the hemispherical groove 913 is further reduced, and the connection stability is reduced, in order to increase the further movement range of the auxiliary guide frame 8 under the limitation, the main guide frame 7 and the first end 93 can realize vertical swinging and horizontal swinging relatively while being rotationally connected, so that the universal joint 92 and the auxiliary guide frame 8 integrally show a movement with a larger angle under the condition that the main guide frame 7 does not perform horizontal displacement. 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 movement range of the auxiliary guide frame 8.
Of course, in some embodiments, the distance between the main guide frame 7 and the auxiliary guide frame 8 may be adjusted to adapt to a larger range of adjustment space, specifically, the strut includes a first section 923 and a second section 921 that are connected in a telescopic manner, where the ends 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 are provided with a screw, the telescopic connection is achieved by using a nut sleeve 922, and the first section 923 and the second section 921 with opposite rotation directions are made to approach or separate from each other by adjusting the nut sleeve 922 to achieve telescopic connection.
On the basis of the above scheme, considering that the main guide frame 7 and the auxiliary guide frame 8 can be relatively adjusted in a relatively large number of directions, for example, the sliding drums 912 locking the first end heads 93 at two sides of the main guide frame 7 cannot rotate the corresponding first universal balls 914, at this time, the auxiliary guide frame 8 can only rotate with the first universal balls 914 of the second end heads 91, and the situation is applicable to the situation that the main hoisting position is unchanged and only the auxiliary hoisting position needs to be adjusted slightly. For example, when the sub-guide frame 8 is adjusted, the slide cylinder 912 in the second end 91 of the sub-guide frame 8 can be locked and adjusted with the adjacent first end 93 as the rotation center, and this is suitable for a case where the main hoisting position is unchanged and the sub-hoisting position needs to be adjusted relatively largely.
For example, the sliding cylinder 912 on one side of the sliding cylinder 912 which can lock the second end 91 of the auxiliary guide frame 8 and the sliding cylinder 912 on the first end 93 on both sides of the main guide frame 7 rotate around the first universal ball 914 in the second end 91 of the auxiliary guide frame 8 on the remaining side, and the situation is suitable for the situation that one side auxiliary lifting position is tight and the main lifting position and the other auxiliary lifting position need to be adjusted, so as to achieve the purpose of overturning the partition wall main body. In this third scenario, it is necessary to slacken the transmission chain that is being tightened, and the transmission chain at the other two positions continues to remain clamped, where clamping refers to clamping the transmission chain more tightly than to the transmission chain at the slackening side, rather than over-clamping.
Specifically, a second sliding ball 918 is disposed in the inner hole of the sliding cylinder 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 (e.g. by adopting a fitting manner of the first universal ball 914 and the hemispherical groove 913) on the 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, on which the second universal ball 919 is not arranged, is provided with a second guide rubber, and a transmission channel corresponding to the transmission chain is formed between the first guide rubber 910 and the second guide rubber. That is, it means that the two first guide rubbers 910 in the main guide frame 7 form a transmission path of the main transmission chain 6, and that the sub guide frame 8 forms a transmission path of the sub transmission chain 5 between the first guide rubbers 910 and the second guide rubbers.
Wherein the first guide rubber 910 and the second guide rubber are used for guiding and damping the corresponding driving chain to maintain the stability of the driving chain in operation. In addition, since the principle of mirror movement of the first universal ball 914 and the second universal ball 919 is utilized, when one of them rotates, the other one will follow to rotate, so that in the third setting, the secondary guide 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 guide rubber 910 and the second guide rubber move mutually, and a larger gap appears, especially in the embodiment that the middle positions of the first guide rubber 910 and the second guide rubber are relatively convex, the secondary transmission chain 5 in the secondary guide frame 8 starts to loose, that is, the corresponding transmission channel is opened, and the transmission channel of the primary transmission chain 6 and the other secondary transmission chain 5 remains unchanged, that is, relatively clamped state, so as to adapt to the purpose of stable overturning of the partition wall main body in the third setting.
