AI Technical Summary
When lifting heavy objects, the existing lifting mechanism is limited due to the space occupied by the electric telescopic rod.
A lifting mechanism is designed, adopting a horizontal bracket structure, and pulley components are installed at both ends. The axial line of the pulley components is parallel to the width direction of the bracket structure. The projection of the two sets of pulley components is located on a straight line. Each set of pulley components is equipped with an electric telescopic rod near one side of the bracket structure. The telescopic end of the electric telescopic rod is arranged diagonally with the pulley components, and the hanging member is connected by a wire rope.
Through the synchronous expansion and contraction of the electric telescopic rod, the lifting of the suspender can be simultaneously driven to prevent the heavy objects from deflecting. At the same time, since the electric telescopic rod is horizontally distributed, it does not occupy vertical space, which increases the height of the heavy objects being lifted.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lifting equipment, and particularly relates to a lifting mechanism. Background Art
[0002] At present, when handling heavy objects, sometimes a lifting mechanism is used to lift the heavy object with two lifting points. However, since the two lifting points on some heavy objects are symmetrically arranged at both ends of the heavy object, when lifting the heavy object, two lifting members are required to lift the two lifting points on the heavy object respectively. And to prevent the heavy object from tilting, after lifting the heavy object, the two lifting members need to be lifted synchronously. In the prior art, some lifting mechanisms realize the synchronous lifting of the lifting members by setting two groups of vertically oppositely distributed electric telescopic rods. However, with the above setting method, since the telescopic end of the electric telescopic rod occupies a certain space in the vertical direction after retracting, the height at which the heavy object can be lifted will be limited. Therefore, there are still drawbacks and deficiencies in the prior art. Content of the Utility Model
[0003] The purpose of the utility model is to provide a lifting mechanism to solve the problems raised in the above background art.
[0004] The technical solution adopted by the utility model to solve the above problems:
[0005] A lifting mechanism includes a lifting assembly. The lifting assembly includes a horizontally arranged and strip-shaped support structure. Pulley assemblies are installed at both ends of the support structure. The axial lines of the pulley assemblies are all parallel to the width direction of the support structure, and the projections of the two groups of pulley assemblies in the vertical direction are located on a straight line parallel to the length direction of the support structure. Electric telescopic rods are respectively arranged on one side of each group of pulley assemblies close to the length direction of the support structure. The electric telescopic rods are all horizontally installed on the support structure and can be synchronously telescoped. The telescopic ends of the two electric telescopic rods respectively face the pulley assemblies diagonally, and a steel wire rope is arranged between the telescopic end of each electric telescopic rod and the diagonally arranged pulley assembly. The end of the steel wire rope far from the electric telescopic rod is wound around the pulley assembly and a lifting member is installed.
[0006] Further, one of the pulley assemblies is higher than the other group of pulley assemblies. The two electric telescopic rods are located on the same side of the pulley assemblies. The two electric telescopic rods are respectively a first electric telescopic rod and a second electric telescopic rod. The second electric telescopic rod is higher than the first electric telescopic rod, and the telescopic end of the second electric telescopic rod is diagonally arranged with the pulley assembly at a higher position. The telescopic end of the first electric telescopic rod is diagonally arranged with the pulley assembly at a lower position, and the steel wire rope connected to the telescopic end of the first electric telescopic rod is shorter than the other group of steel wire ropes. The length difference between the two groups of steel wire ropes is adapted to the height difference between the two groups of pulley assemblies.
[0007] Further, one end of the electric telescopic rod away from the steel wire rope is respectively hinged to the end of the support structure through a hinge shaft, the hinge shaft is vertically distributed, and both ends of the hinge shaft are respectively connected to the support structure.
[0008] Further, U-shaped frames with U-shaped openings away from the electric telescopic rods are installed at the telescopic ends of the electric telescopic rods, detachable pin shafts are installed in the U-shaped frames, and one end of the steel wire rope close to the electric telescopic rod is respectively sleeved on the pin shafts through wire rope clamps.
[0009] Further, each pulley assembly includes a pulley shaft arranged parallel to the width direction of the support structure, both ends of the pulley shaft are respectively connected to the support structure, and pulleys are coaxially sleeved on the pulley shaft.
[0010] Further, a housing is covered on the support structure.
[0011] Further, the number of the lifting assemblies is two groups.
[0012] Adopting the above technical solutions, the beneficial effects of the present utility model are as follows:
[0013] When the present utility model is in use, through the telescoping of the electric telescopic rod, the hanging member can be driven to lift and lower through the steel wire rope. Since the projections of the two pulley assemblies in the vertical direction are located on a straight line arranged parallel to the length direction of the support structure, the two hanging members can be symmetrically distributed at both ends of the support structure, so as to facilitate the use of the two hanging members to respectively lift two symmetrically distributed hanging points on the heavy object. Then, after the heavy object is lifted, by synchronously retracting the telescopic ends of the two electric telescopic rods, the two hanging members can be synchronously driven to lift, so as to prevent the heavy object from tilting. Since the electric telescopic rods are horizontally distributed, and steel wire ropes are installed between the telescopic ends of the electric telescopic rods and the hanging members, when the telescopic ends of the electric telescopic rods retract, no space is occupied in the vertical direction, so that the height of the heavy object lifted can be increased, which is convenient for use.

Detailed Implementation Manner
[0019] To make the objectives, technical solutions, and beneficial effects of the present utility model clearer, the following further describes the implementation manners of the present utility model in detail with reference to the accompanying drawings.
[0020] As Figures 1 to 4 shown, the present utility model provides a lifting mechanism, including a lifting assembly 1. The lifting assembly 1 includes a horizontally arranged and strip-shaped support structure 11. Pulley assemblies 12 are installed at both ends of the support structure 11. The axial lines of the pulley assemblies 12 are all parallel to the width direction of the support structure 11, and the projections of the two pulley assemblies 12 in the vertical direction are located on a straight line parallel to the length direction of the support structure 11. Specifically, each pulley assembly 12 includes a pulley shaft 121 arranged parallel to the width direction of the support structure 11. The two ends of the pulley shaft 121 are respectively connected to the support structure 11, and pulleys 122 are coaxially sleeved on the pulley shaft 121; on each side of each pulley assembly 12 close to one side in the length direction of the support structure 11, an electric telescopic rod 13 is further provided to Figure 1 take as an example, the electric telescopic rod 13 is located on the back side or the front side of the pulley assembly 12; the electric telescopic rod 13 can be set as a hydraulic cylinder; the electric telescopic rods 13 are all horizontally installed on the support structure 11 and can be synchronously telescoped. The telescopic ends of the two electric telescopic rods 13 respectively face the pulley assemblies 12 one by one and are diagonally arranged with the pulley assemblies 12. A steel wire rope 14 is provided between the telescopic end of each electric telescopic rod 13 and the diagonally arranged pulley assembly 12. The end of the steel wire rope 14 away from the electric telescopic rod 13 is installed with a hanging member 15 after passing around the pulley assembly 12. Specifically, the steel wire rope 14 passes around the pulley 122 from the top of the pulley 122; and the hanging member 15 can be set as a hook or a hanging ring and is located below the support structure 11.
[0021] In use, through the telescoping of the electric telescopic rod 13, the lifting member 15 can be driven to lift and lower by the steel wire rope 14. Since the projections of the two pulley assemblies 12 in the vertical direction are located on a straight line parallel to the length direction of the support structure 11, the two lifting members 15 can be symmetrically distributed at both ends of the support structure 11, so as to facilitate using the two lifting members 15 to respectively lift two symmetrically distributed lifting points on the heavy object. Then, after lifting the heavy object, by synchronously retracting the telescopic ends of the two electric telescopic rods 13, the two lifting members 15 can be synchronously lifted to prevent the heavy object from tilting. Since the electric telescopic rods 13 are horizontally distributed and steel wire ropes 14 are installed between the telescopic ends of the electric telescopic rods 13 and the lifting members 15, when the telescopic ends of the electric telescopic rods 13 retract, they do not occupy space in the vertical direction, thereby increasing the height at which the heavy object is lifted for easy use.
[0022] Further, as Figure 1 shown in Figure 2 Figure [specific figure number not provided], one of the pulley assemblies 12 is higher than the other pulley assembly 12. The two electric telescopic rods 13 are located on the same side of the pulley assemblies 12, and the two electric telescopic rods 13 are respectively the first electric telescopic rod 131 and the second electric telescopic rod 132. The second electric telescopic rod 132 is higher than the first electric telescopic rod 131, and the telescopic end of the second electric telescopic rod 132 is diagonally arranged with the pulley assembly 12 at a higher position, and the telescopic end of the first electric telescopic rod 131 is diagonally arranged with the pulley assembly 12 at a lower position. In this way, when the telescopic ends of the two electric telescopic rods 13 are synchronously telescoping, they will not interfere with each other; and since the two electric telescopic rods 13 are located on the same side of the pulley assemblies 12, the width of the support structure 11 can be reduced; and the steel wire rope 14 connected to the telescopic end of the first electric telescopic rod 131 is shorter than the other group of steel wire ropes 14, and the length difference between the two groups of steel wire ropes 14 is adapted to the height difference between the two pulley assemblies 12. In this way, in use, by synchronously retracting the telescopic ends of the two electric telescopic rods 13, the two lifting members 15 can still be synchronously lifted to prevent the heavy object from tilting.
[0023] The specific installation method of the electric telescopic rods 13 horizontally on the support structure 11 is as follows: As Figure 1As shown in the figure, one end of the electric telescopic rod 13 far from the steel wire rope 14 is respectively hinged to the end of the bracket structure 11 through a hinge shaft 19. The hinge shaft 19 is vertically distributed, and both ends of the hinge shaft 19 are connected to the bracket structure 11. Specifically, since the hinge shaft 19 is vertically distributed, the downward inclination amplitude of the electric telescopic rod 13 in the horizontal state can be restricted, so as to ensure that the electric telescopic rod 13 can be normally telescoped; alternatively, a support ring for supporting the barrel of the electric telescopic rod 13 can be installed on the bracket structure 11, and the inner diameter of the support ring is larger than the outer diameter of the barrel of the electric telescopic rod 13 to restrict the downward inclination of the electric telescopic rod 13; secondly, since one end of the electric telescopic rod 13 far from the steel wire rope 14 is hinged to the end of the bracket structure 11, the electric telescopic rod 13 can have a sufficient telescopic length.
[0024] The specific setting method for the connection between the steel wire rope 14 and the telescopic end of the electric telescopic rod 13 is as follows: As Figure 1 shown in the figure, U-shaped frames 16 with U-shaped openings far from the electric telescopic rod 13 are installed at the telescopic ends of the electric telescopic rods 13. Removable pin shafts 17 are installed in the U-shaped frames 16. One end of the steel wire rope 14 close to the electric telescopic rod 13 is respectively sleeved on the pin shaft 17 through steel wire rope clips. Specifically, the steel wire rope clips are prior art. When installing, the steel wire rope clips can be first placed in the U-shaped frames 16, and then the pin shaft 17 is sequentially passed through the U-shaped frames 16 and the steel wire rope clips, and then a split pin is installed on the pin shaft 17 to install the pin shaft 17 on the U-shaped frames 16. In this way, when in use, it is convenient to disassemble and assemble the steel wire rope 14 at the telescopic end of the electric telescopic rod 13.
[0025] Furthermore, as Figure 3 shown in the figure, a housing 18 is covered on the bracket structure 11, and the housing 18 can play a protective role for the whole lifting assembly 1.
[0026] Furthermore, as Figure 4 shown in the figure, the number of the lifting assemblies 1 is two groups. Specifically, the two groups of lifting assemblies 1 can be symmetrically installed on both sides of the frame structure 2. When in use, it is convenient to select four-point lifting of heavy objects according to one's own needs, and the four lifting parts 15 of the two groups of lifting assemblies 1 can be lifted and lowered synchronously to stably lift and transport heavy objects.
