Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention for engineering vehicles, in particular to an angle cable transmission device. Background Art

[0002] In municipal engineering, rainwater and sewage pipes of different diameters should be maintained regularly. Depending on the diameter of the rainwater and sewage pipes, the annual maintenance frequency ranges from 0.2 to 2 times. CCTV or robots are often needed in the maintenance process. No matter which method is used, cables are needed to provide power and communication services to the equipment.

[0003] When the cable enters the manhole through the manhole opening, it needs to change from horizontal to vertical direction before entering the manhole, and adjust the length of the cable into the manhole in real time according to the needs of underground work. This process may have several problems and hidden dangers: First, although the cable has an armor protection layer, the continuous sliding friction on the ground can easily reduce the life of the armor; second, when changing from horizontal to vertical, the hard armor causes a huge inertial impact on the manhole seat, which not only has a certain impact on the life of the manhole seat, but also easily causes defects such as abnormal noise and jumping of the manhole cover. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an angular cable transmission device. In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] An angular cable transmitter comprises a bracket, a mounting frame and a plurality of pulleys. The bracket is enclosed on the outside of a manhole when in use, the mounting frame is fixedly mounted on the top surface of the bracket, the pulley is rotatably mounted between two support plates, and at least one pulley is located above the manhole.

[0006] Furthermore, the shape of the bracket is rectangular, trapezoidal, regular polygonal or circular.

[0007] Furthermore, the mounting frame includes two support plates and a connecting plate fixedly connected between the two support plates, and the shape of the mounting frame is rectangular or trapezoidal.

[0008] Furthermore, the bracket and the mounting frame are made of channel steel, and the bracket and the mounting frame are connected by fastening bolts.

[0009] Furthermore, a rubber sheet cushion is fixedly connected to the bottom of the bracket.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] By placing a bracket on the outside of the manhole, the transported cable is transported into the manhole through the pulley on the mounting frame. The pulley reduces the friction during cable transportation and protects the armor layer and the manhole seat of the cable, making cable transportation more labor-saving and more efficient.

[0015] In the above drawings: bracket 1, mounting frame 2, pulley 3, manhole 4, cable 5, support plate 6, connecting plate 7, cushion layer 8. DETAILED DESCRIPTION

[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1~2 As shown, an embodiment of the utility model proposes an angular cable transmission device, including a bracket 1, a mounting frame 2 and a plurality of pulleys 3. The bracket 1 is enclosed on the outside of a manhole 4 when in use, the mounting frame 2 is fixedly mounted on the top surface of the bracket 1, the pulley 3 is rotatably mounted between two support plates 6, and at least one pulley 3 is located above the manhole 4.

[0018] When the device is used, a bracket 1 is placed outside the manhole 4, and the transported cable 5 is transported into the manhole 4 through the pulley 3 on the mounting frame 2. The pulley 3 reduces the friction during the transportation of the cable 5, protects the armor layer and the manhole seat of the cable 5, and the transportation of the cable 5 is more labor-saving and more efficient.

[0019] In this embodiment, if Figure 2 As shown, the bracket 1 takes a triangle as an example, and the bracket 1 is more stable. In addition, the shape of the bracket 1 is a rectangle, a trapezoid, a regular polygon, or a circle.

[0020] In this embodiment, if Figure 2 As shown, the mounting frame 2 includes two support plates 6 and a connecting plate 7 fixedly connected between the two support plates 6. The mounting frame 2 is rectangular or trapezoidal in shape. The two support plates 6 form a channel for conveying the cable 5, which facilitates the conveying of the cable 5.

[0021] In this embodiment, the bracket 1 and the mounting frame 2 are made of channel steel, and the bracket 1 and the mounting frame 2 are connected by fastening bolts. The device is made of ready-made construction waste, which saves costs.

[0022] In this embodiment, if Figure 1 As shown, a rubber sheet cushion layer 8 is fixedly connected to the bottom of the bracket 1. The cushion layer 8 increases the friction between the bracket 1 and the ground to prevent the bracket 1 from moving during the transportation of the cable 5.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
