Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a railway cable threading pipe group. Background Art

[0002] In railway engineering construction, cable laying is a crucial link, which is directly related to the normal operation of railway communication, signaling and other systems. Especially in the complex railway network environment, cable laying and fixing work is particularly important.

[0003] However, the traditional cable laying method often has problems such as loose fixation and difficult adjustment after the cable is threaded, which not only increases the difficulty of laying, but also affects the service life and safety of the cable. Utility Model Content

[0004] The utility model aims at the technical problems existing in the prior art and provides a railway cable threading tube group to solve the problem that the cables are difficult to lay and fix.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Further, the cable clamping assembly comprises:

[0008] Two groups of clips are arranged opposite to each other, and the opposite sides of the two groups of clips form arc-shaped fitting surfaces adapted to the cable;

[0009] The tightening mechanism connected to the two groups of clamps can drive the two groups of clamps to move closer to each other to clamp the cable.

[0010] Further, the tensioning mechanism comprises:

[0011] A fixed seat and a sliding seat arranged opposite to each other;

[0012] A screw rod disposed on the fixed seat and drivingly connected to the sliding seat;

[0013] A clamping arm hinged to the threading seat and connected to the clamping piece at one end;

[0014] A deflection block is hinged to the other end of the clamping arm, and a connecting rod 1 and a connecting rod 2 which are movably connected to the fixed seat and the sliding seat are respectively hinged to the deflection block.

[0015] Furthermore, the threading seat is also provided with a guide rod which is slidably matched with the sliding seat.

[0016] Furthermore, an adjustment handle is provided at the end of the screw rod.

[0018] Furthermore, the arc-shaped fitting surface of the clip is also provided with an anti-slip pad.

[0019] Moreover, the railway cable threading tube assembly provided by the utility model has at least the following beneficial effects compared with the prior art:

[0020] The designed load-bearing roller group can significantly reduce the friction between the cable and the channel when passing through the threading channel, thereby speeding up the cable threading speed and improving construction efficiency; the cable clamping assembly adopts an arc-shaped fitting surface design, which adapts to the shape of the cable and provides uniform clamping force.

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0028] like Figure 1-Figure 3 As shown, the railway cable threading tube assembly of the utility model comprises a lifting ring 1 and a threading seat 2 arranged below the lifting ring 1; the threading seat 2 has a threading channel opened in the horizontal direction, and the threading seat 2 is provided with a cable clamping assembly 3 and a bearing roller assembly 4 in the upper and lower regions along the threading channel. The lifting ring 1 can be fixed to the lifting point of the railway system by a steel rope or a safety buckle.

[0029] When the cable needs to pass through the threading channel, it is first placed on the load roller set 4 to reduce the friction between the cable and the threading channel. Then, the cable is guided to the position of the cable clamping assembly 3.

[0030] As an implementation method, the cable clamping assembly 3 includes:

[0031] Two groups of clips 3.1 are arranged opposite to each other, and the opposite sides of the two groups of clips 3.1 form an arc-shaped fitting surface adapted to the cable; the arc-shaped fitting surface of the clips 3.1 is also provided with an anti-slip pad 6;

[0032] The tightening mechanism connected to the two groups of clamping pieces 3.1 can drive the two groups of clamping pieces 3.1 to move closer to each other to clamp the cable.

[0033] Specifically, the tensioning mechanism includes:

[0034] A fixed seat 3.2 and a sliding seat 3.3 arranged opposite to each other;

[0035] A screw rod 3.4 disposed on the fixed seat 3.2 and drivingly connected to the sliding seat 3.3;

[0036] A clamping arm 3.5 hinged to the threading seat 2 and connected to the clamping piece 3.1 at one end;

[0037] A deflection block 3.6 is hingedly connected to the other end of the clamp arm 3.5, and a link rod 1 3.7 and a link rod 2 3.8 are hingedly connected to the deflection block 3.6 and are movably connected to the fixed seat 3.2 and the sliding seat 3.3, respectively.

[0038] By rotating the screw 3.4, the screw drives the sliding seat 3.3 to move linearly relative to the fixed seat 3.2. Since the deflection block 3.6 is hinged to the fixed seat 3.2, the sliding seat 3.3 and the clamping arm 3.5 respectively, the movement of the sliding seat will cause the deflection block 3.6 to change its angle through the linkage of the first link 3.7 and the second link 3.8. This angle change causes the clamping arm 3.5 to drive the clamping piece 3.1 to move toward or away from each other.

[0039] When the cable needs to be clamped, the rotation of the screw rod 3.4 drives the sliding seat 3.3 close to the fixed seat 3.2, so that the clamping pieces 3.1 are moved close to each other through the linkage mechanism to clamp the cable. The arc-shaped fitting surface design of the clamping piece can well match the shape of the cable and provide a uniform clamping force, while the provision of the anti-slip pad 6 further enhances the friction between the cable and the clamping piece to prevent the cable from sliding after being fixed.

[0040] In addition, the threading seat 2 is also provided with a guide rod 3.21 which is slidably matched with the sliding seat 3.3, which ensures that the sliding seat 3.3 moves smoothly and stably along a predetermined straight line track under the drive of the screw rod.

[0041] Specifically, an adjustment handle 3.9 is also provided at the end of the screw rod 3.4 to facilitate the adjustment of the screw rod 3.4.

[0042] As an implementation mode, the lifting rings 1 are connected to each other via a universal joint 5, so as to flexibly adjust the position of the entire pipeline after being fixed, so as to meet the overall lifting requirements of the railway cable.
