Description

Technical Field

[0001] The utility model relates to the technical field of tower crane wall-attached dismantling devices, in particular to a tower crane wall-attached dismantling device. Background Art

[0002] The length of a tower crane wall rod is between 3m and 10m, and the weight is between 200kg and 500kg. Since the tower crane cannot rotate during dismantling, the wall tie rod is against the side of the tower crane. The common practice is to use the tower crane hook to pull it diagonally, and then manually pull it to one end of the building to maintain stability. The tie rod and the wall frame and ear plate are separated by the oblique upward pulling force.

[0003] This method can only be used on lightweight wall-mounted rods. Heavy pull rods are difficult for installers to operate and pose a greater safety risk. During operation, the wall-mounted rod may swing greatly and damage the building and tower crane. The pull rod and the ear plate fit together in the horizontal direction, and the ear plate can be easily damaged by pulling upward at an angle. There are generally four installers, and at most two people at one end of the building can pull the traction rope. The workers are laborious and their safety cannot be guaranteed. In order to solve the above problems, a hoist is generally used in conjunction with a tower crane hook to dismantle the wall-mounted rod. During the dismantling process, the wall-mounted rod can be auxiliary supported without manual support, and the coordinated action of the tower crane and the hoist can ensure that the wall-mounted rod will not shake violently.

[0004] However, in actual use, it is necessary to cooperate with the tower crane for auxiliary use, and someone needs to stay on the tower crane to operate it. During the disassembly of the tower crane wall parts, continuing to work on the tower crane will pose a safety hazard, and two people are still required to cooperate to operate the machine, one person controls the tower crane, and the other controls the hoist, thereby increasing cost expenditure.

[0005] Therefore, the utility model provides a tower crane wall-attached removal device. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-Figure 5 As shown, this embodiment provides a technical solution: a tower crane wall removal device, comprising a base 1, a hoist structure 2 is fixedly installed on the top of the outer surface of the base 1, and an auxiliary wire structure 4 is arranged on the outer surface of the hoist structure 2; an auxiliary hook structure 3 is installed on one side of the outer surface of the base 1; the hoist structure 2 comprises two mounting blocks 21, the bottom of the outer surfaces of the two mounting blocks 21 are symmetrically fixedly connected to the top of the outer surface of the base 1, and the inner walls of the mounting blocks 21 and the base 1 are provided with a first threaded hole 22, and the inner wall of the first threaded hole 22 A first bolt 23 is inserted, and the top of the outer surfaces of the two mounting blocks 21 are fixedly connected with a mounting circular plate 24; the auxiliary hook structure 3 includes a rectangular clamping plate 31, one side of the outer surface of the rectangular clamping plate 31 is fixedly connected to one side of the outer surface of the base 1, and a rectangular clamping frame 33 is clamped on the outer surface of the rectangular clamping plate 31, and the top and bottom inner walls of the rectangular clamping frame 33 are provided with a second threaded hole 34, and the inner wall of the rectangular clamping plate 31 is provided with a third threaded hole 32, and the inner walls of the second threaded hole 34 and the third threaded hole 32 are provided with a second bolt 35.

[0030] The first hook 29 and the second hook 313 can be driven to rise and fall respectively by the first steel wire rope 28 and the second steel wire rope 312. At this time, the two sides of the wall-attaching rod can be fixed with the first hook 29 and the second hook 313 respectively according to the actual position of the wall-attaching rod. At this time, under the action of the second steel wire rope 312, the second hook 313 can drive the wall-attaching rod to be separated from the wall-attaching frame and the ear plate, and then under the action of the first hook 29, it can be in a vertical position without shaking. The whole process only requires one person to operate the machine, further reducing the number of staff. Only two people are needed to complete the disassembly and assembly, one person controls the machine, and the other person hangs the first hook 29 and the second hook 313, which is very convenient. Under the action of the auxiliary wire structure 4, the first steel wire rope 28 can be auxiliary guided, and then the steel wire rope can be in the best position for hoisting at different installation positions.

[0031] Further, such as Figure 2-Figure 3As shown: a driving motor 25 is fixedly installed on one side of the outer surface of one of the mounting circular plates 24, and a rotating rod 26 is fixedly connected to the output end of the driving motor 25. The end of the rotating rod 26 away from the driving motor 25 is rotatably connected to one side of the other mounting circular plate 24. A first steel wire rope 28 is wound around the outer surface of the rotating rod 26, and a first hook 29 is fixedly connected to the end of the first steel wire rope 28 away from the rotating rod 26. A first pressing rod 27 is fixedly connected between the two mounting circular plates 24. Two connecting rods 36 are symmetrically fixedly connected to one side of the outer surface of the rectangular card plate 31, and one end of the connecting rod 36 is fixedly connected to a U-shaped frame 37.

The auxiliary rod 39 is away from the second motor 38. One end is rotatably connected to the inner wall of the U-shaped frame 37, and the outer surface of the auxiliary rod 39 is fixedly connected to the winding circular frame 310, and the outer surface of the winding circular frame 310 is wound with a second steel wire rope 312, and the end of the second steel wire rope 312 away from the winding circular frame 310 is fixedly connected to the second hook 313, and the top of the winding circular frame 310 is fixedly connected to the second wire pressing rod 311. The technical effect of adopting the above further scheme is: under the cooperation of the second steel wire rope 312 on the winding circular frame 310 and the first steel wire rope 28 on the hoist structure 2, the first hook 29 and the second hook 313 can stably remove the wall-mounted rod and make it fall to a vertical position and then slowly fall to the ground. This process does not require the use of a tower crane for operation, and a single person can control the machine, thereby reducing the actual operation difficulty and safety risks.

[0032] The above solution also has the problem that the first steel wire rope 28 is prone to friction with the wall, etc. Figure 2 and Figure 3 As shown: in the present scheme, the auxiliary wire structure 4 includes a rotating round rod 41, one end of the outer surface of the rotating round rod 41 is fixedly connected to a circular plate 42, the outer surface of the circular plate 42 is fixedly connected to a first rectangular connecting rod 43, one side of the first rectangular connecting rod 43 is fixedly connected to a wire rod 44, and one end of the wire rod 44 away from the first rectangular connecting rod 43 is fixedly connected to a second rectangular connecting rod 45. The rotating round rod 41 is rotatably set on one side of one of the mounting circular plates 24. Under the action of the wire rod 44, the first steel wire rope 28 can be assisted in guiding, so that it can assist in lifting the wall-mounted rod. At the same time, the angle shell of the wire rod 44 can be adjusted, and then the lifting angle of the first steel wire rope 28 can be different under different installation environments due to different installation positions. After the wire rod 44 is rotated, the angle between the first steel wire rope 28 and the rotating rod 26 can be adjusted.

[0033] The above solution also has the problem that the conductor rod 44 is easily rotated by force after the position adjustment is completed. Figure 2 and Figure 3As shown, a threaded rod 47 is inserted into the inner wall of the circular plate 42, and a nut 48 is threadedly connected to one end of the threaded rod 47, and a threaded clamping rod 410 is threadedly connected to the inner wall of the second rectangular connecting rod 45; a round insertion hole 46 is opened on one side of one of the mounting circular plates 24, and a threaded clamping hole 49 is opened on one side of the other mounting circular plate 24. Under the action of the threaded rod 47 and the nut 48, the first rectangular connecting rod 43 can be auxiliary fixed to the mounting circular plate 24, and under the action of the threaded clamping rod 410 and the threaded clamping hole 49, the second rectangular connecting rod 45 can be auxiliary fixed to the other mounting circular plate 24, so that the wire rod 44 can be fixed after the position adjustment is completed.

[0034] Working principle:

[0035] like Figure 1-5 As shown:

[0036] When in use: first, fit the base 1 to the ground, insert the first bolt 23 into the inner wall of the first threaded hole 22, and then fix it to the ground, then fix the rectangular clamping plate 31 to the rectangular clamping frame 33, and then fix the second bolt 35 to the second threaded hole 34, and then fix it to the ground;

[0037] At this time, the second hook 313 and the first hook 29 are hung and fixed on the wall-attached rod, and the second motor 38 is started, so that the second motor 38 drives the auxiliary rod 39 and the winding round frame 310 to rotate, so that the second steel wire rope 312 can retract and release the wall-attached rod;

[0038] When the wall-attaching rod is separated from the wall-attaching frame, the driving motor 25 is started, so that the driving motor 25 can drive the rotating rod 26 to rotate, and then the first steel wire rope 28 retracts and releases the first hook 29, so that the wall-attaching rod can be placed in a vertical position, and the first hook 29 is separated from it, and the wall-attaching rod is dropped to the ground by the second hook 313 and the second steel wire rope 312;

[0039] When it is necessary to guide the first steel wire rope 28, the first rectangular connecting rod 43 is rotated to drive the conductor rod 44 and the second rectangular connecting rod 45 to rotate, and then they can be rotated to a suitable position. At this time, the threaded plug rod 47 is inserted into the inner wall of the round plug hole 46, and the nut 48 is fixed to the threaded plug rod 47. At the same time, the threaded clamping rod 410 is rotated and clamped into the inner wall of the threaded clamping hole 49 for fixing. At this time, the first steel wire rope 28 can be passed around the conductor rod 44.
