Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of electric hoist mobile auxiliary devices. BACKGROUND

[0002] Currently, a guide rail for lifting equipment is installed on multiple production lines, and 10 electric hoists (10T) are installed on one guide rail. On average, 2 electric hoists are used per line. Due to the limited length of the power cable, to prevent the electric hoist from pulling the cable when it exceeds the stroke, each electric hoist corresponds to a fixed limit block 6, which restricts the movement of the electric hoist within a certain area. The fixed limit block is set on the stroke path of the electric hoist to limit the stroke of the electric hoist. If the fixed limit block is set on the front or rear side of the guide rail, the electric hoist is also slidingly set on the front or rear side of the guide rail. The fixed limit block is not set on the upper side of the guide rail. The problem is that the electric hoist cannot realize cross-lifting of heavy objects, and two electric hoists cannot lift the same heavy object located below them. Specifically, the two adjacent electric hoists are 1# and 2#. If the heavy object is located below 1# and 2# electric hoists, due to the limitation of the fixed limit block, 1# and 2# electric hoists cannot move to the upper side of the heavy object. At this time, the heavy object needs to be moved a certain distance (see a) before it can be located below the lifting range of 1# or 2# electric hoist. However, due to the large weight of the object, manual transfer is dangerous and inefficient. Figure 10 SUMMARY

In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0036] Referring to Figures 1 to 9 The electric hoist moving auxiliary device shown in the drawings, the device comprises a limiting piece 1 and a moving blocking assembly 2, wherein:

[0037] The electric hoist 4 is movably arranged on the guide rail 3, the limiting piece 1 is arranged on the upper side of the guide rail 3 and above the moving path of the electric hoist 4, and the limiting piece 1 will not interfere with the movement of the electric hoist 4, the limiting piece 1 is provided in plurality, the plurality of limiting pieces 1 are arranged along the axial direction of the guide rail 3, and one electric hoist 4 corresponds to two adjacent limiting pieces 1. In some embodiments, the limiting piece 1 is a square body.

[0038] The moving blocking assembly 2 is slidably arranged on the guide rail 3, and the moving blocking assembly 2 is located between the two adjacent limiting pieces 1, the moving blocking assembly 2 comprises a supporting piece and a moving wheel 21, the supporting piece is arranged on the guide rail 3, the moving wheel 21 is rotatably connected with the supporting piece, and the moving wheel 21 is movably arranged on the upper side of the guide rail 3.

[0039] The device has a working state. When in working state, after the support of the moving blocking component 2 abuts against the electric hoist 4, the moving blocking component 2 can slide a certain distance along the guide rail 3 driven by the electric hoist 4 (the moving blocking component 2 and the electric hoist 4 move in the same direction). When the moving wheel 21 abuts against the limiting component 1, the support rotates relative to the guide rail 3 (during rotation, the center position of the moving wheel 21 remains unchanged), that is, the support rotates slightly. As the support rotates, the electric hoist 4 can continue to move along the guide rail 3, so that the electric hoist 4 can move above the heavy object. The electric hoist 4 can then lift the heavy object without the need for manual movement. That is, the electric hoist 4 can move in the area between two adjacent electric hoists 4.

[0040] In this example, the travel of electric hoist 4 is a set travel range, which is within a reasonable range. Electric hoist 4 will not exceed the travel range and damage the cable.

[0041] In some embodiments, the support includes a bracket and a locking member. The bracket is U-shaped, and a movable wheel 21 is disposed in the U-shaped space of the bracket. The movable wheel 21 is rotatably connected to the bracket. The locking member is detachably connected to the bracket and is used to lock the bracket onto the guide rail 3 so that the support is limited between two adjacent limiting members 1 and will not detach from the guide rail 3.

[0042] In some embodiments, the bracket includes an upper plate 22, a left plate and a right plate 23. The left plate and the right plate 23 are both connected to the lower side of the upper plate 22 and are perpendicular to the upper plate 22. A gap is maintained between the left plate and the right plate 23. A U-shaped space is formed between the left plate, the upper plate 22 and the right plate, so that the support member passes through the guide rail 3.

[0043] In this example, when the device is in its initial state, the support is set vertically, that is, both the left and right plates are set vertically; when the device is in operation, the support rotates relative to the vertical center line, and the rotation angle is an acute angle.

[0044] In some embodiments, the locking component includes a screw 24 and two nuts 25. Corresponding threaded holes are provided on the left and right plates. One end of the screw 24 passes through the threaded holes on the left and right plates in sequence, and the screw 24 is threadedly connected to both the left and right plates. The screw 24 is located below the guide rail 3 and is parallel to the upper plate 22. The upper plate 22, left plate, screw 24, and right plate form a hollow quadrilateral structure. The two nuts 25 are respectively located at opposite ends of the screw 24, and abut against the left and right plates to tighten the screw 24, preventing the bracket from detaching from the guide rail 3. When disassembling the moving blocking assembly 2, loosen and remove the nuts 25, then unscrew the screw 24 to detach the bracket from the guide rail 3. When installing the moving blocking assembly 2, first place the bracket on the guide rail 3, then install the screw 24, and then tighten the nuts 25. Installing and disassembling the moving blocking assembly 2 is convenient and quick.

[0045] The left plate of the example keeps a small distance from the side opposite to the guide rail 3, and the right plate keeps a small distance from the side opposite to the guide rail 3, which is beneficial to the rotation of the support support relative to the guide rail 3.

[0046] In some embodiments, the left plate and the right plate are both channel steels, the left plate and the right plate are both U-shaped plates, the left plate and the right plate both have open sides, the open side of the left plate is away from the open side of the right plate, and the two nuts 25 are respectively located at the open side of the left plate and the open side of the right plate.

[0047] In some embodiments, the device further comprises a sleeve 26 sleeved on the screw rod 24, the sleeve 26 is located between the left plate and the right plate, and in the rotation of the support relative to the guide rail 3, the sleeve 26 can abut against the bottom of the guide rail, so that the support stops rotating, the rotation angle of the support relative to the guide rail 3 is limited, and a limiting effect is achieved.

[0048] In the example, the moving wheel 21 is connected with the support through a connecting piece, the connecting piece is fixedly connected with the support, and the moving wheel 21 is rotationally connected with the connecting piece.

[0049] Referring to Figure 4 , the connecting piece comprises an upper connecting plate 27, a left connecting plate and a right connecting plate 28, the upper connecting plate 27 is connected with the upper plate 22, the left connecting plate and the right connecting plate are both connected with the lower side of the upper connecting plate 27, the left connecting plate and the right connecting plate are both perpendicular to the upper connecting plate 27, the left connecting plate, the upper connecting plate 27 and the right connecting plate are arranged in parallel, the left connecting plate, the upper connecting plate 27 and the right connecting plate are in U shape, and a rotating shaft 29 penetrates the left connecting plate, the moving wheel 21 and the right connecting plate in sequence. The moving wheel 21 rotates relative to the rotating shaft 29, and the connecting piece is arranged to facilitate the installation of the moving wheel 21.

[0050] In some embodiments, the plurality of moving blocking assemblies 2 are arranged along the axial direction of the guide rail 3, and each electric hoist 4 corresponds to one moving blocking assembly 2.

[0051] The specific embodiment of the electric hoist moving auxiliary device in the example is as follows:

[0052] If a target heavy object is located below the adjacent two electric hoists, one of the two electric hoists can be operated, and when the electric hoist moves and touches the support, the device moves in the same direction by a distance under the pushing force of the electric hoist until the moving wheel stops by colliding with a limiting piece, and then the electric hoist continues to move and pushes the support to rotate relative to the guide rail, while the electric hoist can continue to move along the guide rail. The electric hoist moves to the area between the adjacent two electric hoists, and then lifts the target heavy object.

[0053] In the example, the distance between the adjacent two limiting pieces is adjustable, and the distance is the distance from the electric hoist trolley to the two ends (the motor end and the reduction box end) of the electric hoist.

[0054] The electric hoist moving auxiliary device of the example has the advantages of:

[0055] The same guide rail is used to realize cross hoisting and long-distance transfer of multiple electric hoists, manual transfer of heavy objects is avoided, safety and convenience are improved, the risk of crushing personnel due to dumping during heavy object transfer is solved, direct hoisting efficiency is significantly improved, and the electric hoist is prevented from being pulled off after exceeding the stroke.

[0056] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and it cannot limit the protection scope of the present application. Any equivalent changes or modifications made in accordance with the spirit and essence of the present application should be covered within the protection scope of the present application.
