Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] Implementation, for example Figures 1 to 6 As shown, a cable clamping device includes a bracket 1 and a clamping device 2. The cable to be fixed is fixed in the clamping device 2. The bracket 1 is a grid-shaped frame structure composed of several channel steels and steel pipes. Four vertical steel pipes 105 and horizontal steel pipes 106 form a grid frame. Vertical movable steel pipes 107 are inserted into the vertical steel pipes 105, so that the height of the entire bracket 1 is adjustable. Angle steel frame 101 is located at the top of the bracket 1. The top and sides of the angle steel frame 101 are provided with elongated holes for installing the clamping device 2. The side support 102 is fixed to the vertical movable steel pipe 107 by pipe clamps, so that the height of the side support 102 is adjustable. The bottom of the four vertical steel pipes 105 is fixed to the inner frame 103 composed of angle steel. The inner frame 103 is surrounded by an outer frame 104 composed of channel steel. Both the inner frame 103 and the outer frame 104 are fixed to the ground 3.

[0021] The clamping device 2 is located on the top or side of the bracket 1, allowing the cable to be clamped and fixed horizontally or vertically as needed. The clamping device 2 includes a chuck 201, a protective cover 202, an upper protective pad 203, a lower protective pad 204, a base 205, a spring 206, a ratchet 207, a swing arm 208, a handle 209, a pawl 210, a tension spring 211, a check pawl 212, and a torsion spring 213. The base 205 is fixed to the angle steel frame 101 or a side support, and the contact surface between the base and the cable is provided with a lower protective pad 204. The chuck 201 is hinged to the base 205, and the side of the chuck 201 in contact with the cable is provided with a protective cover 202 and an upper protective pad 203. The protective pad prevents damage to the cable surface. A rack is provided on the side of the chuck 201, connected to the ratchet mechanism.

[0022] The ratchet mechanism consists of a spring 206, a ratchet 207, a rocker arm 208, a handle 209, a pawl 210, a tension spring 211, a check pawl 212, and a torsion spring 213. The pawl 210 rotates within the ratchet 207 and engages with the rack on the chuck. The function of the pawl 210 is to drive the chuck 201 downwards (clockwise) to clamp the cable. The two ends of the spring 206 respectively abut against the pawl 210 and the ratchet 207. The function of the spring 206 is to keep the pawl 210 in contact with the rack of the chuck 201. When the pawl 210 rotates counterclockwise, it engages with the rack, driving the chuck 201 downwards (clockwise) to clamp the cable. When the pawl 210 rotates clockwise, it disengages from the rack of the chuck 201 and slides along the outer surface of the rack. The ratchet 207 is connected to the base 201 via a pin. 5. The ratchet 207 is hinged to the base 205 via a pin. The ratchet 207 has a drive gear that meshes with the drive gear on the swing arm 208. The swing arm 208 is also hinged to the base 205 via a pin. The swing arm 208 is equipped with a handle 209. A tension spring 211 is also provided between the swing arm 208 and the base 205 to hold one end of the handle 209. The function of the tension spring 211 is to help the swing arm 208 return to its original position quickly, saving manpower and improving efficiency. The check pawl 212 is hinged to the base 205 via a pin. Under the action of the torsion spring 213, the check pawl 212 always keeps in contact with the rack of the chuck 201. That is, the torsion spring 212 is fitted onto the pin of the check pawl 212. The two ends of the torsion spring 212 are respectively inserted into the check pawl 212 and the corresponding small holes on the base 205. The function of the check pawl 212 is to prevent the chuck 201 from loosening (rotating counterclockwise).

[0023] During operation, open the chuck 201 upwards (counter-clockwise), insert the cable to be secured, close the chuck 201, and repeatedly rotate the handle 209 downwards (clockwise) and then upwards (counter-clockwise) to continuously compress the cable. To release, simply release the check pawl 212 (clockwise) and then lift the chuck 201 upwards (counter-clockwise).

[0024] The above-described embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Any equivalent variations made based on the claims of the present utility model shall still fall within the scope of the present utility model.
