When adjusting the direction and position of the cables, direct contact with the cables is inevitable, and there is a risk of abrasions and squeezing of personnel and cables, which poses a major safety hazard to production safety.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model aims to provide an auxiliary device for laying and moving power cables to solve the problems existing in the prior art, and is easy to use, saves labor and reduces operation risks.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1-Figure 3 As shown, the present embodiment provides an auxiliary device for laying and moving power cables, which is made of galvanized steel pipe as a whole, including an inner rod 1, an intermediate sleeve 2, a handrail 5 and a clamping element 4. The intermediate sleeve 2 is rotatably connected to the outer periphery of the inner rod 1, and there is a rotation gap between the inner wall of the intermediate sleeve 2 and the outer wall of the inner rod 1, so that the intermediate sleeve 2 and the inner rod 1 form a roller, ensuring that when the cable contacts the intermediate sleeve 2, the intermediate sleeve 2 can be rotated by external force, thereby assisting in reducing friction and reducing work intensity. The handrail 5 and the clamping element 4 are respectively installed at both ends of the inner rod 1, and the handrail 5 is used for users to hold for easy operation. When in use, the clamping element 4 is used to fix the whole, and the handrail 5 can be grasped to adjust the angle without directly pulling the cable, which effectively reduces the operation risk and reduces the work difficulty. The clamping element 4 can be rotated to be parallel to the inner rod 1 and fixed. This state is a 180° working state (such as Figure 3 As shown), it is suitable for use on cable trays. The clamping element 4 is inserted into the angle iron of the cable tray, and the fixing plane of the cable tray is used to provide reliable support for the whole. Or the clamping element 4 can be rotated to be perpendicular to the inner rod 1 and fixed. This state is a 90° working state (as shown Figure 1-Figure 2As shown), it is suitable for use at corners. The clamping element 4 is used to form a clamping force with the wall at the corner, so that the whole can be reliably supported when the cable passes through.

[0023] Specifically, a plug 3 is provided between the middle sleeve 2 and the handrail 5, and at the end of the inner rod 1 away from the handrail 5. The setting of the plug 3 can prevent the middle sleeve 2 from separating from the inner rod 1, and can also prevent the middle sleeve 2 from moving up and scratching the staff. The plug 3 is fixed to the outer periphery of the inner rod 1, and a moving gap is reserved between the plug 3 and the middle sleeve 2 to ensure that the roller can rotate easily.

[0024] The moving gaps at both ends of the middle sleeve 2 are both 50 mm, and those skilled in the art can adaptively adjust the specific size of the moving gap according to actual needs.

[0025] The locking element 4 is mounted on the plug 3 which is arranged away from the handrail 5, and is preferably fixed by welding.

[0026] The locking element 4 is a fork-shaped locking head, specifically including a vertical rod 6 and a horizontal rod 7. One end of the vertical rod 6 is fixed on the plug 3, and the other end of the vertical rod 6 is rotatably connected to one end of the horizontal rod 7. The horizontal rod 7 is perpendicular to the vertical rod 6, and the horizontal rod 7 can be rotated around the axis of the vertical rod 6 to be parallel to the inner rod 1, or rotated to be perpendicular to the inner rod 1, and after the horizontal rod 7 is rotated into place, it is fixed to the vertical rod 6 through a fixing pin assembly to ensure that the locking element 4 can adapt to different working conditions.

[0027] The plug 3 includes a long straight section and a reducing section. The long straight section is arranged close to the middle sleeve 2, and one end of the long straight section is connected to the reducing section. From approaching to away from the long straight section, the diameter of the reducing section gradually decreases.

[0028] The inner diameter of the long straight section is 32 mm, and the minimum inner diameter of the diameter-changing section is 25 mm. The length of the plug 3 on the side close to the handrail 5 is 150 mm, and the length of the plug 3 on the side away from the handrail 5 is 250 mm. The clamping element 4 is installed on the long straight section.

[0029] The length of the inner rod 1 is 1500 mm, and the outer diameter is 25 mm; the length of the intermediate sleeve 2 is 750 mm, and the inner diameter is 32 mm, and the width of the annular gap between the outer wall of the inner rod 1 and the inner wall of the intermediate sleeve 2 is 7 mm. However, in this embodiment, the above dimensions are not limited to the above limitations, and those skilled in the art can make adaptive changes according to actual needs.

[0030] Through the above-mentioned arrangement, this embodiment solves the technical problem of easy friction damage between cables and corners and cable trays during the laying of power cables, effectively isolates the direct contact between workers and cables during the operation, and reduces the risk of abrasions and squeezing injuries to workers.

[0031] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
