Description
Technical Field
[0001] The invention belongs to the technical field of transmission line wiring construction, and in particular relates to a tension wire clamp pulley matching structure and a pulley construction method. Background Art
[0002] At present, the crimping of the tension clamp and the conductor requires high-altitude work. The operator needs to build a hanging point and a platform at high altitude, and then lift the crimping machine onto the platform to complete the threading of the conductor and the tension clamp, the crimping of the crimping tube, etc. The crimping machine is large in size and weight, and it is time-consuming and laborious to transport and lift. It requires high physical fitness of personnel, large workload, low work efficiency, high labor intensity, and high risk of high-altitude work. If the conductor and the tension clamp are crimped directly on the ground and then pulled over the pulley, the work efficiency and safety can be greatly improved, but the tension clamps have different shapes and the drainage plate protrudes too much, which cannot guarantee safe and smooth passage through the pulley.
[0003] To ensure the performance of the tension clamp, the tension clamp crimped with the conductor cannot pass through the pulley directly, but must be installed as a whole in the protective device, because a rotating connector must be installed between the protective device and the traction board. When the tension clamp passes through the pulley, the drain plate may be at any position in the circumferential direction of the conductor. According to the traditional construction method, the tension clamp and its protective device can only pass through the pulley smoothly when the drain plate is vertically upward. In other positions, the drain plate can easily get caught on the wheel groove or the frames on both sides of the pulley, causing accidents, which is absolutely not allowed in the line laying construction.
[0004] Therefore, it is urgent to design a new tension wire clamp passing pulley matching structure and a pulley passing construction method, so that the conductor and the tension wire clamp can be directly crimped on the ground and then pulled through the pulley, so that the tension wire clamp drainage plate can pass the pulley safely and smoothly, reducing the workload of personnel working at high altitudes and improving the level of mechanized construction and working efficiency. Summary of the invention
[0005] In order to solve the problems in the prior art, the present invention provides a pulley matching structure for a tension wire clamp and a pulley construction method.

[0007] Furthermore, the support plate is a crescent support plate.
[0008] Furthermore, the lower pressure roller assembly includes a lower pressure roller shaft, and a lower pressure roller rotatably connected to the lower pressure roller shaft; an installation position is provided on the upper side of the corresponding balance hammer standard section, and the lower pressure roller is placed at the installation position. At the same time, lower pressure roller shaft pressure plates are provided at both ends of the lower pressure roller shaft, and the lower pressure roller shaft pressure plates are connected to the corresponding balance hammer standard section through screws.
[0009] Furthermore, the installation position is a groove that matches the lower pressure roller, and both ends of the groove are installation planes, and the lower pressure roller shaft pressure plate is fixed on the installation plane.
[0010] Further, the upper pressing roller assembly includes an upper pressing roller shaft, and an upper pressing roller rotatably connected to the upper pressing roller shaft; One end of the upper pressure roller shaft is set as a boss, and the boss is provided with a plurality of fixing holes matching the guide plate, and the boss is connected to the guide plate by screws; The other end of the upper pressing roller shaft is provided with an axial limiting mechanism for the upper pressing roller.
[0011] Furthermore, the axial limiting mechanism includes an upper pressure roller baffle plate sleeved on the upper pressure roller shaft, and the upper pressure roller baffle plate is fixed in position by a spring washer and a nut.
[0012] The invention also discloses a method for constructing a tension wire clamp passing a pulley, comprising the following steps: (1) Equipment preparation; Prepare the tension wire clamp to pass the pulley matching structure; The pulley is a seven-wheel pulley, and the traction board is a one-traction six-board board, ensuring that there is an empty pulley wheel groove on both sides when the tension wire clamp passes through the pulley. This space allows the tension wire clamp drainage board to pass through the pulley smoothly when it is facing the horizontal direction; (2) Equipment connection; Two special counterweights are installed on the second connecting plates on the two outer sides of the traction walking plate, so that the side connecting ear plates of the first section of the counterweight and the supporting plate of the standard section of the counterweight face upward; the tension clamp crimped with the conductor is installed as a whole into the tension clamp protection sleeve, and the upper pressure roller assembly is installed on the drainage plate. The front end of the tension clamp protection sleeve is hinged to the rotary connector, and the other end of the rotary connector is hinged to the side connecting ear plate of the first section of the special counterweight. The section of the special counterweight corresponding to the position of the drainage plate is installed with the lower pressure roller assembly, which forms a roller correction device with the upper pressure roller assembly installed on the drainage plate; (3) The tension wire clamp passes through the pulley; The traction walking plate pulls the special balance hammer through the pulley, and the support plate on the standard section of the balance hammer holds the tension wire clamp protective sleeve onto the pulley. When the front end of the standard section of the balance hammer where the lower pressure roller assembly is located contacts the pulley, the rear part is lifted; if the guide plate is vertically upward or horizontally left and right, the support plate on the special balance hammer holds the tension wire clamp protective sleeve through the pulley smoothly.

[0025] Specifically, the upper pressure roller assembly 7 includes an upper pressure roller shaft 31 and an upper pressure roller 32 rotatably connected to the upper pressure roller shaft 31.
