DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0028] Please refer to Figures 1-4 The utility model discloses a hoisting equipment, which comprises:

[0029] Electric hoist 1 is set up above the travelling crane operation layer and is used for hoisting operation;

[0030] Control cabinet 2 is set up on the walking platform of the travelling crane operation layer, and a cable for controlling electric hoist 1 is arranged between control cabinet 2 and electric hoist 1.

[0031] Sliding mechanism 3 is set up above the travelling crane operation layer, and sliding mechanism 3 comprises moving assembly 31 for driving electric hoist 1 to move along the length direction of the travelling crane and towline assembly 32 for winding and unwinding the cable during the movement of electric hoist 1.

[0032] The utility model, through the control cabinet 2 that sets up originally at electric hoist 1 is transferred to the walking platform of the travelling crane operation layer, and the cable winding and unwinding when electric hoist 1 walks is regulated by utilizing towline assembly 32, so that the electric maintenance personnel when processing electrical fault, avoid the direct saving the time required in the process of nine meters high straight ladder access, eliminate the danger of personnel falling, tool falling, spare parts falling in the process, realize the purpose of reducing maintenance workload.

[0033] In an embodiment, the control cabinet 2 is detachably provided with a control terminal connected with the control cabinet 2 in signal, and the control terminal is used for remote control of the electric hoist 1 by an operator.

[0034] In this way, when hoisting, disassembling and replacing the spare parts of the travelling crane, the operator can use the control terminal to remotely control the electric hoist 1 from a safer and more convenient position, which can further improve the safety in use compared with the existing wired controller.

[0035] In an embodiment, the moving assembly 31 is composed of a first guide rail 311 arranged in parallel with the length direction of the travelling crane and a wheeled walking part 312 capable of reciprocating on the first guide rail 311, and the wheeled walking part 312 is connected with the electric hoist 1 and used to drive the electric hoist 1 to reciprocate along the first guide rail 311.

[0036] The towline assembly 32 is composed of a second guide rail 321 arranged in parallel with the length direction of the travelling crane and a plurality of clamping parts 322 capable of reciprocating on the second guide rail 321, and the clamping parts 322 are used to clamp the cable, and a connecting rod 323 is arranged between the clamping parts 322 close to the wheeled walking part 312 and the wheeled walking part 312.

[0037] In this way, the wheeled walking part 312 is used to walk on the first guide rail 311 to drive the electric hoist 1 to move, so that the electric hoist 1 can perform hoisting operation at different positions of the travelling crane, and the connecting rod 323 is arranged to connect the wheeled walking part 312, so that when the electric hoist 1 moves, the clamping parts 322 are driven to move along the second guide rail 321 synchronously, and when the cable between two adjacent clamping parts 322 is straightened due to movement, the subsequent clamping part 322 is driven to move, and through the movement of the plurality of clamping parts 322, the cable is released, and conversely, when the electric hoist 1 moves reversely, the clamping parts 322 are tightly attached to each other to complete the folding and storage of the cable. Since the clamping parts 322 and the wheeled walking part 312 move on different guide rails respectively, the weight of the sliding mechanism 3 is distributed on the two guide rails, which can not only improve the running stability, but also effectively reduce the running wear.

[0038] It should be noted that the wheeled walking part 312 and the clamping part 322 are common knowledge in the art, and therefore the specific structure and working principle thereof will not be described in detail herein.

[0039] In an embodiment, the second guide rail 321 is provided with a flip cover mechanism 4 used to shield the opening of the second guide rail 321.

[0040] The flip cover mechanism 4 comprises a turnover motor 41 arranged on the second guide rail 321, an output end of the turnover motor 41 is provided with a rotating rod 42, the flip cover mechanism 4 further comprises a cover plate 43 arranged on one side of the opening of the second guide rail 321, the cover plate 43 is rotationally connected with the second guide rail 321 through a torsion spring, and the cover plate 43 blocks the opening of the second guide rail 321 when the torsion spring is in a natural state, and a plurality of pull ropes 44 are arranged between the rotating rod 42 and the cover plate 43.

[0041] In this way, when the sliding mechanism 3 is in an idle state, the cover plate 43 blocks the opening of the second guide rail 321 by the action of the torsion spring, so that the high-altitude smoke directly enters the second guide rail 321 through the opening of the second guide rail 321, and the problem of increasing the moving resistance of the clamping part 322 due to long-term accumulation of smoke is avoided as much as possible, and when the sliding mechanism 3 needs to work, the turnover motor 41 is started to wind the pull rope 44 on the rotating rod 42, so that the cover plate 43 is turned over by overcoming the torsion of the torsion spring, so that the cover plate 43 no longer blocks the opening of the second guide rail 321.

[0042] In the embodiment, the cover plate 43 only covers part of the opening of the second guide rail 321, and the remaining uncovered area is the occupied area when the plurality of clamping parts 322 are closely attached.

[0043] In an embodiment, the clamping part 322 is provided with a blocking strip 5 located in the opening area of the second guide rail 321, and the blocking strip 5 is provided with a strip-shaped brush abutting against the second guide rail 321.

[0044] In this way, the uncovered area of the opening of the second guide rail 321 is protected by the cooperation of the blocking strip 5 and the strip-shaped brush, the amount of smoke entering from the gap between the clamping part 322 and the second guide rail 321 is reduced, and the problem of smoke accumulation is further reduced.

[0045] It should be noted that if the present application involves directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition and the like between the components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications also change accordingly.

[0046] In addition, if the description of "first", "second" and the like is involved in the embodiments of the present application, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor in the protection scope required by the present application.

[0047] In addition, "a plurality of" means two or more.

[0048] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
