Description

Technical Field

[0001] The invention belongs to the technical field of cable fixing clamps, and in particular relates to a cable clamp and an operating method for facilitating cable installation and replacement. Background Art

[0002] Cable is an electric energy or signal transmission device, usually composed of several or several groups of wires, mainly used for multiple functions such as control installation, connecting equipment, and transmitting electricity. In the power, communication and other industries, the laying and maintenance of cables is an important and complicated task. Cable clamps are often used to clamp and fix cables during the installation process. Cable clamps are used to fix cables after laying and installation to prevent the cables from being displaced due to external forces or their own weight. The cable clamps can ensure that the cables are arranged neatly after laying without cross arrangement, and can prevent eddy current losses. When using existing cable clamps, the cables are usually clamped with a clamp seat and then tightened with bolts. This method is not convenient for adjusting the direction and position of the cable, and is not convenient for later cable installation and replacement. It requires a lot of manpower and time. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a cable clamp and an operating method that are convenient for cable installation and replacement, so as to solve the problems raised in the background technology.

[0004] The objective of the present invention is achieved in this way: a cable clamp which is convenient for cable installation and replacement, comprises a base, a cycloidal groove is arranged on the front side of the base, a side platform is arranged on the rear side of the base, a moving block is arranged on the outer side of the side platform, a top block is arranged on the upper side of the moving block, a pressure plate is arranged on the outer side of the top block, a positioning seat is arranged in the middle part of the base, a connecting rod is movably arranged inside the positioning seat, the upper end of the connecting rod is hinged to the moving block through a chuck, a driving head is arranged at the lower end of the connecting rod, a limiting groove is arranged inside the driving head, a pin head is arranged at the lower end of the driving head, a driving disk is arranged inside the base, the driving disk is connected to the base through a limiting pin, the limiting pin and the limiting groove are clamped with each other, an arc groove is arranged on the lower side of the driving disk, and the arc groove and the pin head are clamped with each other.

[0005] The upper side of the side platform is provided with a side groove, and the side groove and the shifting block are mutually engaged.

[0006] A control box is arranged on the outside of the base, a worm wheel is arranged inside the control box, a central axis of the worm wheel is fixedly connected with a limit pin, a worm is meshedly arranged on the outside of the worm wheel, and a handle is arranged on the outer end of the worm wheel.

[0007] A wire clamping plate is arranged below the top block, a partition is arranged between the wire clamping plate and the top block, the partition is screwed to the top block through an adjusting bolt, and the wire clamping plate is inserted into the inside of the partition through a buffer rod.

[0008] Two buffer rods are symmetrically arranged, and a buffer spring is arranged between the buffer rod and the partition plate.

[0009] The cycloid groove and the clamping plate are both arc-shaped.

[0010] A swivel seat is arranged at the lower side of the base, the swivel seat is connected to the base through a bearing plate, a gear plate is arranged at the bottom of the bearing plate, an adjusting screw is threadedly arranged at the outer side of the swivel seat, a tooth block is arranged at the inner end of the adjusting screw, and the tooth block is meshed with the gear plate.

[0011] Support feet are evenly arranged on the outer side of the rotating seat.

[0012] A method for operating a cable clamp for facilitating cable installation and replacement comprises the following steps: Step 1: Before use, check whether all parts of the device are intact and ensure that they are not loose or damaged. According to the diameter and type of the cable, adjust the distance between the pressure plate and the partition by rotating the adjustment bolt; Step 2: Fix the device in place with the support legs, use the bearing plate to adjust the base direction, and place the cable in the cycloid groove. The arc-shaped design of the cycloid groove helps to place the cable firmly. Step 3: Rotate the handle to control the movement of the drive head through the control box, and then drive the moving block and the top block to move through the connecting rod. The top block will push the pressure plate to move toward the cable until the cable is tightly clamped; Step 4: When the cable needs to be installed or replaced, rotate the handle in the opposite direction to release the clamping force of the pressure plate on the cable, then take out the cable and install or replace it.

[0013] The beneficial effects of the present invention are as follows: the setting of the adjusting bolt allows the spacing between the clamping plate and the partition to be adjusted according to the diameter and type of the cable, thereby ensuring that the cable is firmly clamped without being damaged. The setting of the buffer rod and the buffer spring further enhances the stability of the clamping process and reduces the impact and damage to the cable during clamping. By rotating the handle, the worm can be driven to rotate, thereby driving the worm wheel and the limit pin to move, simplifying the operation process of cable clamping and releasing, so that the cable can be easily installed and replaced. The mutual cooperation of the connecting rod, the driving head, the limit groove and the arc groove ensures the stability of the moving block and the top block when clamping the cable, and effectively prevents the cable from shaking or falling off during the clamping process. The setting of the swivel seat and the adjusting screw allows the angle and direction of the clamp to be adjusted as needed, thereby meeting the needs of different working environments and cable directions.

[0024] A side groove 16 is provided on the upper side of the side platform 3 , and the side groove 16 and the shifting block 4 are engaged with each other.

[0025] When the present invention is in use, the cable is placed in the cycloidal groove 2, the cycloidal groove 2 and the cable are matched with each other, and the limit pin 14 is rotated. As the limit pin 14 rotates, the pin head 11 moves along the arc groove 15 of the driving disk 13.
