The device includes an upper structural floor and a lower structural floor. A discharging platform is fixedly arranged above the lower structural floor. Through holes are respectively arranged on the upper and lower sides of the outer side wall of the upper structural floor. PVC sleeve joints matching the through holes are arranged in the through holes. A U-shaped round steel is inserted and matched in the two PVC sleeve joints. The straight edge of the U-shaped round steel extends out of the inner side of the outer side wall of the upper structural floor. The extending end of the straight edge of the U-shaped round steel is a threaded structure, and a nut is arranged in a matching manner. A steel wire rope is connected between the bent edge of the U-shaped round steel and the discharging platform.

[0004] When using the above device to tie and fix the discharging platform, there are the following problems: First, when installing the U-shaped round steel and tying the steel wire rope of the discharging platform, workers need to work at heights using a scaffolding near the edge of the main structure, which is prone to high-altitude falling accidents; second, the traditional U-shaped round steel has a relatively large arc part, and the steel wire rope will displace at the arc part when stressed, causing wear. Content of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the utility model provides a steel wire rope tying device for a discharging platform, which solves the problem that in the prior art, due to the relatively large arc part of the traditional tying device, the steel wire rope will displace at the arc part when stressed, causing wear.

[0017] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0018] As Figures 1 to 3As shown, an embodiment of the utility model proposes a wire rope pulling device for a discharge platform, which includes a U-shaped frame 1, including a first straight portion 101 and a second straight portion 103, and an arc portion 102 smoothly connected to one end of the first straight portion 101 and the second straight portion 103, wherein the length of the first straight portion 101 is two-thirds of the length of the second straight portion 103, and the ends of the first straight portion 101 and the second straight portion 103 away from the arc portion 102 are both threadedly connected with nuts 3; a clamping assembly, which is divided into two groups and is respectively arranged at the threaded ends of the first straight portion 101 and the second straight portion 103, and the clamping assembly is used to clamp the traction rope; a protective plate 2 is arranged between the U-shaped frame 1 and the floor 100, and is used to prevent the U-shaped frame 1 from causing wear to the floor 100.

[0019] The detailed working process of this embodiment is as follows: the U-shaped frame 1 is used to be installed on the building to tie and fix the unloading platform, and the clamping assembly is used to clamp the traction rope, and the U-shaped frame 1 is vertically lifted to the designated position by the traction rope for installation.

[0020] By changing the conventional U-shaped structure, the length of the first straight portion 101 is set to two-thirds of the length of the second straight portion 103, and then one end with a height difference is smoothly connected through the arc portion 102, so that the force-bearing area of ​​the arc portion 102 connected to the wire rope is reduced, reducing the displacement of the wire rope in the arc portion when it is stressed, thereby reducing wear and tear. At the same time, its installation position is changed according to its characteristics, from the conventional horizontal installation to the vertical installation, avoiding the problem of high-altitude operations.

[0021] like Figure 3 As shown, each clamping assembly includes two clamping arms 4 that are arranged in mirror image, and each clamping arm 4 is made of elastic material.

[0023] The detailed working process of this embodiment is as follows: by clamping one end of the traction rope through the two clamping arms 4, the U-shaped frame 1 can be lifted by lifting the traction rope, and when the two clamping arms 4 clamp the traction rope, the elastic force of their own elastic material is used to provide support. At the same time, since one end of the short axis portion 402 and the long axis portion 403 are correspondingly fixedly installed on the first straight portion 101 and the second straight portion 103, when clamping, the two corresponding clamping arms 4 are directly pried apart to move away from each other. At this time, the clamping arms 4 accumulate force, and then the traction rope is placed between the two corresponding clamping arms 4. When the clamping arms 4 are released and reset, the traction rope can be clamped.

[0024] likeFigure 3 As shown, each of the opposite sex parts 401 is covered with a rubber sleeve 404 .

[0027] The detailed working process of this embodiment is as follows: the function of the pad portion 201 is to increase the force-bearing area of ​​the nut 3, and the function of the pipe column portion 202 is to prevent the building wall from directly contacting the first straight portion 101 and the second straight portion 103 to cause wear.

[0028] like Figure 2 As shown, washers 301 are sleeved on the first straight portion 101 and the second straight portion 103 , and the washers 301 are located between the corresponding nuts 3 and the pad portion 201 .

[0029] The detailed working process of this embodiment is as follows: the function of the gasket 301 is to disperse the pressure of the nut 3 on the surface of the connecting piece during the tightening process, so as to avoid damage to the connecting piece caused by excessive local pressure.

[0030] The implementation principle of the embodiment of the present application is as follows: first, a hole is drilled on the floor 100 at the installation position at the construction site, and then the pipe column part 202 in the protective plate 2 is inserted into the corresponding hole, and then the traction rope is passed through the pipe column part 202 and placed on the ground, and then the two corresponding clamping arms 4 are opened to make them move away from each other, and then one end of the traction rope is placed between the two corresponding clamping arms 4, and then the clamping arms 4 are released and reset to clamp the traction rope, and then the traction rope is recovered to lift the U-shaped frame 1 and pass it through the pipe column part 202, and then the gasket 301 is installed, the nut 3 is tightened, and the U-shaped frame 1 is fixed in the worthwhile position, and then one end of the wire rope can be connected to the U-shaped frame 1 to tie and fix the unloading platform.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
