Technical Field

[0001] This utility model relates to the field of optical cable laying technology, and in particular to a cable trench cable laying support pulley device. Background Technology

[0002] Since fiber optic cable laying must be carried out during maintenance windows and the use of large equipment is not permitted, appropriate cable laying tools are required for the operation. During on-site work, laying new fiber optic cables can cause friction, twisting, and other damage to existing fiber optic cable joints in the cable trench, hindering the rapid deployment of the cable within the trench. Therefore, suitable tools are needed to facilitate smooth cable laying. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a cable trench cable laying support pulley device, which aims to solve the technical problem in the prior art that the laying of new optical cables will cause friction, twisting and other damage to the existing optical cable joints in the cable trench, thus affecting the smooth laying of cables.

[0005] Furthermore, in this utility model, the length of the short support rod is 1 / 3 of the length of the long support rod, and the front ends of the short support rod and the long support rod are aligned.

[0006] Furthermore, in this invention, one of the vertical connecting segments is connected to the rear end of the short support rod, and the other vertical connecting segment is connected side-by-side to the long support rod.

[0007] Furthermore, in this invention, the length of the pulley is slightly less than the length of the horizontal support section.

[0008] Furthermore, in this invention, the two positioning rods are respectively positioned near the front ends of the long support rod and the short support rod.

[0009] Furthermore, in this invention, the length of the positioning rod is 1 / 3 of the length of the vertical connecting section.

[0010] Furthermore, the long support rod, short support rod, pulley support rod, and positioning rod described in this utility model are integrally formed.

[0011] Furthermore, the outer surfaces of the long support rod, short support rod, pulley support rod, and positioning rod described in this utility model are all provided with a protective coating.

[0012] Compared with the prior art, this utility model has the following advantages: This utility model can be used on a cable cover plate, and the new cable can be laid on the pulley, so that the new cable is suspended in the air and a space is formed between it and the existing cable, which facilitates the laying of the cable and will not cause friction, twisting or other damage to the existing cable joints. At the same time, it can also protect the existing cable joint box. In areas with high safety risks, the joint box occupies a lot of space in the cable trench and has many sharp edges and bolts. Conventional cable laying methods can easily cause the new cable to get caught or wrapped around the cable joint box, causing cable breakage and damage at the joint box, resulting in communication interruption. The device of this utility model can facilitate the smooth laying of cables. Attached Figure Description

[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] Example:

[0018] The accompanying drawings illustrate a specific embodiment of the cable trench cable laying support pulley device of this utility model. Figure 1 It mainly includes a long support rod 1 and a short support rod 2 arranged at intervals. The length of the short support rod 2 is 1 / 3 of the length of the long support rod 1. The front ends of the short support rod 2 and the long support rod 1 are set at the same length.

[0019] A pulley support rod 3 connects the long support rod 1 and the short support rod 2. The pulley support rod 3 has two vertical connecting sections 3a and one horizontal support section 3b. The upper ends of the two vertical connecting sections 3a are connected to the long support rod 1 and the short support rod 2 respectively. One vertical connecting section 3a is connected to the rear end of the short support rod 2, and the other vertical connecting section 3a is connected to the long support rod 1 side by side. The two ends of the horizontal support section 3b are connected to the lower ends of the two vertical connecting sections 3a respectively.

[0020] A pulley 4 is rotatably mounted on the horizontal support section 3b, and the length of the pulley 4 is slightly less than the length of the horizontal support section 3b.

[0021] Positioning rods 5 are also connected to the long support rod 1 and the short support rod 2 respectively. The two positioning rods 5 are respectively set near the front end of the long support rod 1 and the short support rod 2. The length of the positioning rods 5 extends downward and is 1 / 3 of the length of the vertical connecting section 3a.

[0022] In this embodiment, the long support rod 1, the short support rod 2, the pulley support rod 3, and the positioning rod 5 are integrally formed, resulting in a stable overall structure and high strength.

[0023] In this embodiment, the outer surfaces of the long support rod 1, the short support rod 2, the pulley support rod 3, and the positioning rod 5 are all provided with a protective coating, thereby effectively extending their service life.

[0024] When this utility model is used in a specific way, such as Figure 2 As shown, the long support rod 1 and the short support rod 2 are mounted on two spaced cable cover plates D. When placing the entire device, the short support rod 2 is first lowered into the cable trench A. The worker then places the newly laid cable C around the short support rod 2 onto the pulley 4, and then lifts the short support rod 2 and the long support rod 1 together onto the two spaced cable cover plates D. The two positioning rods 5 at the front end are used for positioning. When placing the device, the positioning rods 5 are stopped after contacting one of the cable cover plates D. At this time, the newly laid cable C is laid on the pulley 4. The newly laid cable C is suspended in the air, forming a gap between it and the existing cable B, which facilitates cable laying and will not cause friction, twisting or other damage to the existing cable joints. At the same time, it can also protect the existing cable joint boxes. In areas with high safety risks, the joint boxes occupy a lot of space in the cable trench and have many sharp edges and bolts. Conventional cable laying methods can easily cause the newly laid cable to get caught or wrapped around the cable joint box, causing cable breakage and damage at the joint box, resulting in communication interruption. The device of this utility model can facilitate the smooth laying of cables. It should be noted that during actual construction, there are several cable cover plates D along the length of cable trench A. Therefore, the device of this utility model can be placed in several pieces according to actual construction needs to play a role in coordinating cable laying.

[0025] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
