Description

Technical Field

[0001] The invention belongs to the technical field of cable laying, and in particular relates to a cable laying protection structure. Background Art

[0002] Nowadays, the cable laying process usually uses conveyors for laying construction. The conveyors are powered by distribution boxes at the construction site. However, due to the loss of electric energy during the transmission process, the conveying speeds of the conveyors are different when conveying cables, causing the cables to be out of sync during the transportation process. Especially in the case of high-altitude differences, the cables may fall out of the groove, become "bulged", or become suspended. This not only affects the normal laying of the cable, but also causes damage to the outer sheath and the inside of the cable.

[0003] Therefore, based on the experience of on-site construction, a new type of cable laying protection structure was developed. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cable laying protection structure to better lay cables and avoid damage to the cable outer sheath and the inside of the cable.

[0005] The present invention solves the technical problem by the following technical solutions:

[0007] Moreover, the fixed pulley and the movable pulley are both arc-surface pulleys with thick ends and thin middles, cables are clamped in the middle of the fixed pulley and the movable pulley, and the curvature of the arc surface of the fixed pulley and the movable pulley is the same as the curvature of the cable.

[0008] Moreover, two ends of the second connecting rod extend out of the left column and the right column respectively and fixed limit bolts are installed at the ends.

[0009] Moreover, both ends of the third connecting rod extend out of the left column and the right column and are fixedly connected by fastening bolts.

[0010] Furthermore, two ends of the first connecting rod extend out of the left column and the right column respectively and the ends are fixedly connected by fastening bolts.

[0011] Moreover, the upper sections of the left column and the right column are both provided with mounting seats, and the pressure controller is mounted on the mounting seats.

[0012] Moreover, the base is a U-shaped base.

[0013] The advantages and beneficial effects of the present invention are:

[0014] The present invention achieves stable clamping of the cable and controls the direction of the cable through a fixed pulley and a movable pulley, and simultaneously achieves fine adjustment of the direction of the cable by longitudinally fine-tuning the movable pulley through a pressure controller and a pressure spring, thereby preventing the cable from falling out of the groove, being "convex", or being suspended, and ensuring the normal laying of the cable; at the same time, the outer sheath and the inside of the cable can be protected.

[0022] The present invention is further described in detail below through specific examples. The following examples are only illustrative and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0023] like Figures 1 to 4As shown, a cable laying protection structure, the innovation of which lies in: comprising a base 6 and a left column and a right column installed on the base, a fixed pulley 7 and a movable pulley 9 are installed on the left column 5 and the right column 8 from top to bottom in sequence, the fixed pulley is installed on a first connecting rod 14, the two ends of the first connecting rod are respectively fixed to the left column and the right column, the movable pulley is installed on a second connecting rod 13, the second connecting rod is longitudinally slidably installed in a longitudinal slide groove 2 provided on the left column and the right column, and the upper ends of the left column and the right column are respectively fixedly installed with a third connecting rod 11, A pressure spring 12 is installed between the third connecting rod and the second connecting rod section on the left column and the right column, and a pressure controller 1 is installed on the top of the left column and / or the right column. The pressure controller is connected to the pressure spring. The present invention completes the stable clamping of the cable through the fixed pulley and the movable pulley to control the direction of the cable. At the same time, the movable pulley is longitudinally fine-tuned by the pressure controller and the pressure spring to complete the fine-tuning of the direction of the cable, which can prevent the cable from falling out of the groove, "bulging", hanging in the air, etc., thereby ensuring the normal laying of the cable; at the same time, it can also protect the outer sheath and the inside of the cable.

[0024] The fixed pulley and the movable pulley are both arc-surface pulleys that are thick at both ends and thin in the middle. The cables are clamped in the middle of the fixed pulley and the movable pulley. The curvature of the arc surface of the fixed pulley and the movable pulley is the same as the curvature of the cable, ensuring stable and accurate clamping of the cable and protecting the cable.

[0025] The two ends of the second connecting rod extend out of the left column and the right column respectively and fixed limit bolts 3 are installed at the ends to prevent the second connecting rod from moving in the left and right directions and ensure the stability of its vertical fine-tuning movement.

[0026] Both ends of the third connecting rod extend out of the left column and the right column and are fixedly connected by fastening bolts 4. Both ends of the first connecting rod extend out of the left column and the right column respectively and the ends are fixedly connected by fastening bolts, thereby ensuring the connection stability of the fixed pulley and the pressure spring, and ensuring the stability of the movable pulley when adjusting up and down under the action of the pressure regulator.

[0027] The upper sections of the left column and the right column are both provided with mounting bases 10, on which the pressure controller is mounted, so as to ensure stable installation of the pressure controller.

[0028] The base is a U-shaped base to ensure stable support for the left and right columns.

[0029] The working principle of the present invention is:

[0030] like Figure 5As shown, before the cable is transported, the structure is fixed at the front end and the rear end of the conveyor and at a position with a height difference. The cable clamp is installed on the fixed pulley and the movable pulley, and the pressure spring is installed. The pressure controller is adjusted and the first, second and third connecting rods are inserted. The fastening bolts and the fixed limit bolts are installed. After the cable is fixed, the cable laying process is carried out.

[0031] The connecting rod of this structure can move up and down during the cable transportation process. The connecting rod cooperates with the pulley and the pressure springs in the left and right columns to adjust the up and down and lateral pressure of the cable to prevent the cable from slipping out of the groove, "bulging" or hanging in the air during transportation. It ensures the normal laying of the cable and protects the outer sheath and the inside of the cable.

[0032] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
