AI Technical Summary

Problems solved by technology

However, the actual working conditions of the stretching machine are relatively complicated, and the weight of the wire is relatively large. Various problems may arise in the cooperation between the reel and the wire. Fast, which leads to the phenomenon that the transmission line speed is too high, the cable wires fall messily, and the speed of the reel is inconsistent with the speed of the wire when the speed is too high, resulting in the problem of inaccurate measurement of the pay-off size; in addition, the stretcher works outdoors , When it is sunny, it is exposed to direct sunlight, which will easily cause the temperature of the machine to be high, and because the tension generating device of the stretching machine will also generate more heat, the machine is easy to overheat and cause equipment damage
Moreover, after the above problems occur, it cannot be fed back to the operator or the control system in time, causing further problems in the system
Moreover, the angle of the reel cannot be adjusted as needed after the equipment is installed, etc.

Embodiment 1

[0030] see Figure 1-3 , shows the intention of a transmission line stretcher for evaluating the carrying capacity of a construction enterprise in Embodiment 1 of the present invention, which includes a chassis 1, a bracket 2 arranged on the chassis, and a reel 3 installed on the bracket 2 . The reel 3 is driven by a motor 4 , and preferably, a reducer 5 is arranged between the motor 4 and the reel 3 . When the stretcher is used as the tension applying device, the drive motor 4 and the speed reducer 5 may not be present.

[0031] Wherein, the stretcher further includes a state monitoring device, which includes an MCU and a GPS module connected thereto, a vibration monitoring module, a rotation monitoring module, a temperature monitoring module, a charging module, and a WIFI module. Among them, the GPS module is used to monitor the working position and altitude of the machine; the vibration monitoring module records the vibration of the stretcher during work through vibration...

Embodiment 2

[0037] like Figure 4-7 It shows the mechanism diagram of the tension machine of embodiment 2, wherein, compared with embodiment 1, it adds an anti-overspeed device, specifically, it includes a box body 8, which is arranged inside the box body 8 and on the reel shaft The bull gear 31, the pinion 91 meshing with it, and the reduction gear 9 coaxially arranged with the pinion 91.

[0038] The deceleration device 9 includes a rotating base 92, an outer peripheral part 93 fixedly connected to the outer side of the rotating base 92 and having through holes formed in some positions, an elastic part 94 arranged in the through hole, one end of the elastic part 94 is connected to the rotating The base body 92 is fixedly connected, and the other end is connected with the friction block 95 . A friction shoe 96 is provided at the position of the friction block 95 in the box body 8 . There is a certain gap between the friction block 95 and the friction shoe 96 . Elastic member 94 can be...

Embodiment 3

[0047] Figure 8-9 It shows the structural diagram of the tension machine of Embodiment 3 of the present invention. Embodiment 3 focuses on the heat dissipation structure, and the structures of other parts may be the same as those of Embodiment 1-2.

[0048] The tension applying device in the tension machine of this embodiment mainly includes a hydraulic motor, a pump and a speed increaser. Among them, the hydraulic speed increaser is arranged between the hydraulic motor and the drum to adjust the rotating speed. A hydraulic pipeline is connected between the hydraulic oil outlet and the inlet of the hydraulic motor, and a pump is arranged on the pipeline to drive the flow of the hydraulic oil.

[0049] Among them, the focus of this embodiment is that part of the hydraulic pipeline is arranged underground, preferably within 1 meter, more preferably greater than 50 centimeters, because the temperature underground in summer is significantly lower than that on the ground, and the...

Abstract

The invention relates to a power transmission line stretching machine for evaluating the bearing capacity of a construction enterprise. The stretching machine comprises a bottom frame, a support arranged on the bottom frame and a winding drum installed on the support, and is characterized by further comprising a state monitoring device which comprises an MCU, a GPS module, a vibration monitoring module, a charging module and a WIFI module, and the GPS module, the vibration monitoring module, the charging module and the WIFI module are connected with the MCU. By the adoption of the stretching machine, data such as vibration, the rotating speed and the temperature of the stretching machine can be monitored in real time, an alarm or a command can be sent out in time when a problem occurs, theproblem and damage of a wire or the stretching machine can be effectively avoided, stable work of the stretching machine is guaranteed, and the accuracy of bearing capacity evaluation of a 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 stretcher 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 of substations and line pr...
