DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. It is understandable that the drawings are only provided for reference and illustration, and are not used to limit the utility model. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a cable protection device provided by the utility model; Figure 2 It is a structural schematic diagram of the fixing mechanism in the utility model; Figure 3 It is a structural schematic diagram of the first pulley and the second pulley in the utility model; Figure 4The schematic diagram of the structure of the adjustment mechanism in the utility model. A cable protection device comprises a cross bar 1, an extension bar 3 is fixedly connected to one side of the cross bar 1, a first pulley 4 is rotatably connected to the inner wall of the extension bar 3, and a second pulley 6 is arranged on one side of the first pulley 4; a fixing mechanism 2, the fixing mechanism 2 comprises a motor 21 arranged on the top of the cross bar 1, a connecting rod 22 is slidably connected to the inner wall of the cross bar 1, the number of the connecting rods 22 is two, the output shaft of the motor 21 is fixedly connected to a driving wheel 23, the outer side of the driving wheel 23 is meshedly connected to a driven wheel 24, a screw rod 25 is fixedly connected to the center of the driven wheel 24, the outer side of the screw rod 25 is screwed to the inner wall of the connecting rod 22 The adjusting mechanism 5 comprises a connecting block 51 which is slidably connected to the inner wall of the extension rod 3, the inner wall of the connecting block 51 is rotatably connected to one end of the second pulley 6, a limiting hole 52 is provided on the inner wall of the extension rod 3, a limiting rod 53 is slidably connected to the inner wall of the connecting block 51, the limiting hole 52 is engaged with the limiting rod 53, there are two limiting rods 53, one end of the limiting rod 53 is fixedly connected to a fixing block 54, the bottom of the fixing block 54 is fixedly connected to a spring 55, one end of the spring 55 is fixedly connected to the top of another fixing block 54.

[0021] It should be noted that: moving the fixing block 54 brings the two fixing blocks 54 closer to each other, so that the limiting rod 53 can be separated from the limiting hole 52 and the fixation of the connecting block 51 can be released. At this time, the spring 55 is in a compressed state. Then the connecting block 51 is moved to drive the second pulley 6 to move, so that the distance between it and the first pulley 4 can be increased or reduced, thereby facilitating the threading operation of cables of different sizes. Then the fixing block 54 is released, and the limiting rod 53 can be automatically inserted into the limiting hole 52 through the rebound force of the spring 55 to fix the second pulley 6. Then the motor 21 is started to make the active wheel 23 drive the driven wheel 24 to rotate. The rotation of the driven wheel 24 can drive the screw rod 25 to rotate. The rotation of the screw rod 25 can make the two connecting rods 22 drive the top plate 26 to move, so that the top plate 26 can be pressed against the wall of the cable well, and then the device can be fixed on the cable well. The operation is convenient and the work efficiency when fixing the device is improved.

[0022] In the specific implementation process, Figure 1 and Figure 2 As shown, one side of the connecting rod 22 is fixedly connected to a limiting block 27, and the inner wall of the cross bar 1 is provided with a limiting groove, and the limiting block 27 is slidably connected to the limiting groove.

[0023] It should be noted that when the connecting rod 22 drives the top plate 26 to move, it can drive the limit block 27 to move in the limit groove. Through the coordinated use of the limit block 27 and the limit groove, the connecting rod 22 can be prevented from rotating with the screw rod 25, and at the same time, the stability of the connecting rod 22 during movement can be improved.

[0024] refer to Figure 1 , Figure 3 and Figure 4 As shown, a lever 56 is fixedly connected to one side of the fixed block 54 , and a positioning block 57 is fixedly connected to the other side of the fixed block 54 . A positioning groove is formed on the inner wall of the connecting block 51 , and the positioning block 57 is slidably connected to the positioning groove.

[0025] It should be noted that moving the lever 56 can bring the two fixed blocks 54 closer to each other. When the fixed block 54 moves, it can drive the positioning block 57 to move in the positioning groove. Through the coordinated use of the positioning block 57 and the positioning groove, the fixed block 54 can remain stable during movement, thereby allowing the limit rod 53 to maintain vertical movement.

[0026] refer to Figure 1 As shown, a handle 7 is fixedly connected to the top of the crossbar 1 , and an anti-slip sleeve 8 is provided on the outer side of the handle 7 .

[0027] It should be noted that the handle 7 facilitates the operator to move the device, and the anti-slip sleeve 8 increases the friction between the operator's hand and the handle 7 to prevent the operator from slipping due to sweating when holding the handle 7.

[0028] The working principle of a cable protection device provided by the utility model is as follows:

[0029] When in use, first adjust the second pulley 6 through the adjustment mechanism 5 to increase or decrease the distance between it and the first pulley 4, so as to facilitate the threading operation of cables of different sizes. Then, a person holds the handle 7 to move the device above the cable well and starts the fixing mechanism 2 to fix the device on the wall of the cable well. This is convenient and quick, improves the work efficiency of the fixing device, and avoids manual fixing by personnel, which is difficult to operate.
