Description

Technical Field

[0001] The invention relates to the technical field of combined cable test lines, and in particular to a combined cable test line fixing device. Background Art

[0002] Although people use cables in many scenarios, early cable tests were relatively casual, and cable test lines were usually tied and fixed with ropes and tapes. With the development of the electric power industry, the application scenarios of modular cables are increasing, which requires modular cables to be fixed in different environments for testing. Therefore, people have studied and produced modular cable test line fixing devices.

[0003] For the existing combined cable test line fixture, it is necessary to manually place the combined cable on top of the fixture. Since the combined cable is heavy and tough, it is difficult for workers to pull it manually, which increases the workload of workers and reduces their work efficiency to a certain extent. At the same time, the combined cable may become loose and fall during the experiment due to the small contact area of ​​the clamped cable. In addition, after the test is completed, the cable test line has many dismantling steps, which makes it inconvenient for workers to place and take it out. Summary of the invention

[0004] The purpose of the present invention is to provide a combined cable test line fixing device, which makes it easier for the staff to pull the combined cable when the staff needs to manually place the combined cable above the fixing device, thereby reducing the workload of the staff and improving the work efficiency of the staff to a certain extent. At the same time, the contact area for clamping the cable is increased, reducing the probability of the combined cable loosening and falling during the experiment. After the test is completed, the dismantling steps are fewer, which makes it convenient for the staff to place and remove the combined cable.

[0005] In order to achieve the above-mentioned purpose, a combined cable test line fixing device is provided, including a fixed table, a slot is opened inside the fixed table, a sliding block is slidably placed inside the slot, a blocking block is fixedly connected to the right end of the slot, a second friction plate is fixedly connected to the upper surface of the sliding block, a sliding shaft is fixedly connected to the front and rear surfaces of the sliding block, the outer surface of the sliding shaft and the inner surface of the slot are slidably connected, a first rotating shaft and a second rotating shaft are fixedly connected to the front and rear surfaces of the sliding block, the outer surfaces of the first rotating shaft and the second rotating shaft are respectively fixedly connected to the first bracket and the second bracket, a second support plate is fixedly connected to the bottom center of the fixed table, a bidirectional lead screw is rotatably connected to the inside of the second support plate, and a pinion is fixedly connected to the front end of the bidirectional lead screw.

[0008] According to the combined cable test line fixing device, a fifth rotating shaft is rotatably connected to the interior of the upper end of the first bracket, and a pulling rod is rotatably sleeved on the outer surface of the fifth rotating shaft.

[0009] According to the combined cable test line fixing device, the left end of the pulling rod is rotatably connected to a support shaft, and the outer surface of the support shaft is fixedly connected to a traction rope.

[0010] According to the combined cable test line fixing device, the left end of the traction rope is fixedly connected to a roller, and the outer surface of the roller is fixedly connected to a first support plate.

[0011] According to the combined cable test line fixing device, the upper surface of the fixing platform is fixedly connected to a base, and the upper surface of the base is fixedly connected to a first motor.

[0012] According to the combined cable test line fixing device, the bottom surface of the third support plate is fixedly connected to the second motor, and the front surface of the second motor is fixedly connected to the large gear.

[0013] Beneficial effects:

[0014] 1. When the staff needs to pull the cable test line and place it above the fixing device, put the cable test line head between the first friction plate and the second friction plate, then start the first motor, the first motor will drive the roller to continuously reel in the traction rope, so that the pulling rod is pulled inward, and the upper ends of the first bracket and the second bracket will also be pulled, so that the fixing plate and the first friction plate gradually move closer to the second friction plate, until the first friction plate and the second friction plate clamp the cable test line, at this time the cable test line will follow the sliding block to pull inward, when the staff completes the experiment, they only need to start the first motor again to rotate in the opposite direction, at this time the staff pulls the cable test line outward, due to the friction force, the first bracket and the second bracket will rotate in the opposite direction, so that the fixing plate and the first friction plate gradually move away from the second friction plate, so that when the staff places the combined cable on the fixing device, it is easier to pull and place the combined cable, reducing the workload of the staff and improving the work efficiency of the staff to a certain extent.

[0015] 2. After the staff has placed the cable test line, the second motor is started to rotate, so that the large gear drives the small gear and the two-way screw to rotate at the same time, so that the first sliding plate drives the second sliding plate and the extrusion plate to slowly clamp inward at the same time. When the extrusion plate clamps the cable test line, the staff pauses the second motor. After the test is completed, the second motor is started again to rotate in the opposite direction, so that the large gear drives the small gear and the two-way screw to rotate in the opposite direction at the same time, so that the first sliding plate drives the second sliding plate and the extrusion plate to move slowly outward at the same time, so that the cable fixing device increases the contact area for clamping the cable, reduces the probability of the cable test line loosening and falling during the experiment, and after the test is completed, the dismantling steps are fewer, which is convenient for the staff to place and remove the combined cable.
