Technical Field

[0001] The utility model belongs to the field of power laying auxiliary equipment, in particular to a load-bearing cable returning auxiliary device. Background Art

[0002] When laying out the existing contact network load-bearing cables, due to the influence of special procedures, the load-bearing cables will be connected to the compensation first, so that the load-bearing cables have tension. Especially when the large curve is relaxed on the flat wrist arm or the joint double wrist arm is relaxed on the line, manpower is generally used to relax it, and a rail car is needed for construction work. 2-3 people are needed for construction, and the construction efficiency is slow, the risk factor is high, and the construction cost is high. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a load-bearing cable return auxiliary device to solve the problem that the load-bearing cable is inconvenient to install when the line is slowed down.

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] A load-bearing cable return auxiliary device comprises a positioning sleeve, a rotating member rotatably connected to the positioning sleeve, a fixing buckle arranged on the rotating member and a driving device for driving the rotating member to rotate, wherein the driving device is arranged on the positioning sleeve and the fixing buckle is used to fix the load-bearing cable.

[0006] Furthermore, the rotating member includes a worm wheel, and the driving device includes a worm meshing with the worm wheel and a handle drivingly connected to the worm wheel.

[0007] Furthermore, a lifting ring is provided on the positioning sleeve, and a lifting piece is detachably connected to the lifting ring.

[0008] Furthermore, the fixing buckle is wrapped with a rubber pad.

[0009] Furthermore, a positioning bolt is threadedly connected to the positioning sleeve, and the positioning bolt is perpendicular to the length direction of the positioning sleeve.

[0010] Furthermore, the fixing buckle includes a quick-release clamp, and a connecting rod is provided between the fixing buckle and the rotating member.

[0011] Furthermore, the quick-release clamp is rotatably connected to the connecting rod.

[0012] The significant beneficial effects achieved by the utility model are:

[0013] When the curve is large and the angle is large, the cable has been tensioned and the load-bearing cable is located under the wrist before it is relaxed, so the force is large. Before this, this process was completed by manual shoulder-carrying. Now, a worm gear set is used to save effort and return the load-bearing cable to the load-bearing cable seat. The worm gear has a natural self-locking feature. The application is simple to operate, has a large torque, and is safe to use. It effectively solves the problem of inconvenient installation when the load-bearing cable is relaxed.

[0014] The setting of the lifting ring can be used when the load-bearing cable cannot be installed on the fixing buckle by manpower. By installing the lifting piece on the lifting ring, the lifting piece can then lift the load-bearing cable to the fixing buckle for easy fixation.

[0015] The rubber pad on the fixing buckle can prevent the fixing buckle from damaging the load-bearing cable.

[0016] The setting of the positioning bolt can fix the positioning sleeve at the end of the arm to prevent the positioning sleeve from being displaced.

[0017] The setting on the connecting rod of the quick-release clamp rotation connection can easily change the direction of the end of the load-bearing cable, so as to facilitate the installation of the load-bearing cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, a load-bearing cable return auxiliary device is installed at the end of the arm, including a positioning sleeve 1 sleeved on the end of the arm, a rotating part rotatably connected to the front of the positioning sleeve 1, a fixing buckle 2 installed on the rotating part and a driving device for driving the rotating part to rotate, and the fixing buckle 2 is used to fix the load-bearing cable.

[0026] The rotating member includes a worm wheel 3, and the driving device includes a worm 4 meshing with the worm wheel 3 and a handle 5 connected to the worm 4 in a transmission manner; the worm wheel 3 is rotatably mounted on the positioning sleeve 1, and the worm 4 is rotatably connected to the positioning sleeve 1;

[0027] When the curve is large and the angle is large, the cable is under the flat wrist arm because the cable has been tensioned and the cable is under the flat wrist arm before it is relaxed. Before this, this process was completed by shouldering manually. Now, the worm gear 3 and worm 4 gear set are used to save effort and return the cable to the cable seat. The worm gear 3 and worm 4 have the characteristics of natural self-locking.

[0028] When installing the load-bearing cable, first fix the load-bearing cable on the fixing buckle 2, then rotate the handle 5 to drive the worm gear 3 to rotate, and then drive the load-bearing cable to pass around the end of the wrist arm and be installed on the load-bearing cable seat. The application is simple to operate, has a large torque, is safe to use, and effectively solves the problem of inconvenient installation of the load-bearing cable when the line is slow.

[0029] Example 2

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. This embodiment is further optimized on the basis of embodiment 1. Before the load-bearing cable is installed on the fixing buckle 2, sometimes it is difficult to manually move the load-bearing cable to the fixing buckle 2 due to the tension. Therefore, in this embodiment, a lifting ring 6 is installed under the positioning sleeve 1, and a lifting component 7 is detachably connected to the lifting ring 6. In this embodiment, the lifting component 7 is an electric hoist or a manual hoist. The load-bearing cable is fixed and moved to the fixing buckle 2 through the setting of the lifting component 7, which is convenient for the staff to install the load-bearing cable on the fixing buckle 2, saving time and effort, and being convenient and quick.

[0031] Example 3

[0032] like Figure 1-Figure 4As shown, the structure of this embodiment is roughly the same as that of embodiment 2. This embodiment is further optimized on the basis of embodiment 2. In order to prevent the positioning sleeve 1 from being displaced after being sleeved on the end of the arm, a positioning bolt 10 is threadedly connected in front of the positioning sleeve 1, and the positioning bolt 10 is perpendicular to the length direction of the positioning sleeve 1; after the positioning sleeve 1 is sleeved on the end of the arm, the positioning sleeve 1 is fixed by rotating the positioning bolt 10 so that the positioning bolt 10 abuts against the arm;

[0033] In order to prevent the fixing buckle 2 from damaging the load-bearing cable, the fixing buckle 2 is wrapped with a rubber pad 8;

[0034] In order to facilitate the installation of the load-bearing cable on the fixing buckle 2, the fixing buckle 2 is a quick-release clamp in this embodiment, and a connecting rod 9 is installed between the fixing buckle 2 and the rotating member. The connecting rod 9 is parallel to the positioning sleeve 1 and extends to the outside of the worm gear 3. The fixing buckle 2 is located outside the worm gear 3 by setting the connecting rod 9, which facilitates the installation of the load-bearing cable.

[0035] At the same time, the upper end of the quick-release clamp is rotatably connected to the connecting rod 9 through a bearing. The setting of the rotatable connection of the quick-release clamp can change the direction of the end of the load-bearing cable, making it convenient to install the load-bearing cable on the load-bearing cable seat.
