Problems solved by technology

[0004] However, generally speaking, the stretcher is a relatively large electromechanical device, and it often works with a high-power motor, which has problems of relatively large vibration and noise
Moreover, the stretcher is installed in the outdoor field, and the soil conditions are complex, and because the stretcher itself is heavy, part of the soil layer often subsides during work, resulting in instability of the stretcher and greater vibration of the machine. , the inclination of the stretching machine will also cause the inclination of the reel. At this time, the strength of the wire received by the reel changes, which affects the normal stretching of the wire
Moreover, the angle between the reel and the wire needs to be adjusted sometimes, and the existing stretching machine either cannot be adjusted or the adjustment method is complicated and inconvenient

Embodiment 1

[0032] see Figure 1-5 , which shows a schematic diagram of a transmission line tensioner with vibration reduction for evaluating the carrying capacity of a construction enterprise according to Embodiment 1 of the present invention, which includes a first chassis 1, a second chassis 2, and a bracket arranged on the second chassis 3, and the reel 4 installed on the bracket 3, the reel 4 is driven by a motor 5, and a vibration-damping structure 7 is arranged between the first chassis 1 and the second chassis 2. Preferably, a speed reducer 6 is provided between the motor 5 and the reel 4, and wheels are also included. When the stretcher is used as a tension applying device, the driving motor 5 and the reducer 6 do not drive the reel to rotate, but apply tension.

[0033] The damping structure 7 includes a first support 71, a second support 72 and a damping elastic member 73 arranged between them, wherein the first support 71 includes a bottom plate and a cylindrical structure, ...

Embodiment 2

[0036] Such as Figure 6-9 As shown, in the stretching machine according to the second embodiment of the present invention, compared with the first embodiment, the damping device can also adjust the angle of the reel relative to the wire, and actively adapt to the local subsidence of the soil. Specifically, its main structure includes a first support member 71, a second support member 72, a damping elastic member 73, and a filler 722; Figure 4 The difference is that a flexible connecting portion 725 is added between the top plate 720 and the protruding structure below. one-way valve). The flexible connecting part 725 can be made of soft steel wire, soft steel strip, rigid and flexible resin material, etc. In the initial state, the flexible connecting part 725 is in a straightened structure under the gravity of the protruding structure. When the protruding structure and The distance between the top plates 720 becomes smaller, and they are in a bent recovery state.

Embodiment 3

[0050] Figure 9 It shows the stretcher solution of Embodiment 3 of the present invention, wherein, compared with the solution of Embodiment 2, a baffle plate 74 and a height adjustment device 75 are added, specifically, above the bottom plate of the first support member 1 or Below the top plate of the second support member, a height adjustment device 75 is connected, such as a screw structure. Wherein, the baffle is an annular structure, and the hole in the center thereof can cooperate with the cylindrical structure of the first support 1 or the protruding structure of the second support 2 and can slide on it. The height of the baffle plate 74 relative to the bottom plate can be adjusted by rotating the height adjusting device 75 , and then the length of the damping elastic body 73 can be adjusted. By adopting such a solution, the elastic force exerted by the damping elastic body 73 can be adjusted as required. Especially when it is necessary to adjust the length of the dam...

Abstract

The invention relates to a power transmission line stretching machine with vibration reduction for bearing capacity evaluation of a construction enterprise. The machine comprises a bracket and a winding drum arranged on the bracket, and is characterized by further comprising a first underframe and a second underframe above the first underframe, a vibration reduction structure is arranged between the first underframe and the second underframe, and the bracket is arranged on the second underframe. By the adoption of the stretching machine, vibration can be effectively reduced, the angle of the winding drum can be conveniently adjusted, change of the angle of the winding drum and increase of vibration caused by sedimentation of soil are effectively prevented, stable work of the stretching machine is guaranteed, and the accuracy of bearing capacity evaluation of the construction enterprise is improved.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a transmission line construction device, in particular to a transmission line tensioner with vibration reduction for evaluating the carrying capacity of construction enterprises. Background technique [0002] With the rapid development of the economy, the construction of the domestic power grid is also increasingly vigorous, correspondingly, a large number of construction enterprises have grown and grown accordingly. At the same time, due to the large amount of power grid construction projects and relatively strict time requirements, the construction capabilities of construction companies are highly required. Furthermore, the accurate assessment of the carrying capacity of the enterprise becomes a basis for the expected completion and progress of the construction project. [0003] The current evaluation of the carrying capacity of construction enterprises mainly considers the data o...
