Description

Technical Field

[0001] The utility model belongs to the field of cable assistance, and in particular relates to an auxiliary tooling for upper and lower plates of high-voltage cables. Background Art

[0002] When high-voltage cables are produced in each process, they need to go through the steps of wire laying-out-process operation-wire winding. During the wrapping, argon arc welding and extrusion processes, especially for high-voltage cables, the weight and volume will become larger and larger, and it will become extremely difficult to get the cable ends up and down.

[0003] At present, the method of getting high-voltage cables on and off the reel is to tie a steel wire rope to the cable end and wind it on the reel via a traction machine. The operator needs to lift the cable end to assist in getting the cable on and off the reel. In order to reduce the burden on the operators, a simple load-bearing tool is designed. At the distance between the reel and the traction machine, the cable end can be placed on the tool and transported to the front of the reel. However, this tool only serves the function of transportation. The operator still needs to lift the cable end on and off the reel and fix the end on the reel with a steel wire rope. Then, as the reel rotates, the cable is slowly wound on the reel. Getting the cable on and off the reel is still a great burden for the operators. Utility Model Content

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] like Figure 1 to Figure 2As shown, the utility model is a high-voltage cable upper and lower drum auxiliary tooling, which is used to pull the cable on the pay-off frame 10 into the retractable frame through the auxiliary tooling, wherein the auxiliary tooling includes: a mobile frame 2, on which a mounting frame 20 is movably arranged; a receiving mechanism 3, which is horizontally installed on the mounting frame 20, and the receiving mechanism 3 is used to pull the cable in the pay-off frame 10 onto the mounting frame 20; a conveying mechanism 4, which is arranged on the mounting frame 20 and is located on one side of the receiving mechanism 3, and the conveying mechanism 4 has an adjusting pulley 40 that can be switched at any position between the initial position and the maximum rotation position; the adjusting pulley 40 at the initial position The adjusting pulley 40 in the maximum rotation position is arranged colinearly with the receiving mechanism 3, and the adjusting pulley 40 in the maximum rotation position is arranged at an angle with the receiving mechanism 3 to adjust the cable end on the conveying mechanism 4 toward the cable entrance 110 in the storage rack; the height adjustment mechanism 5 is symmetrically distributed on the mobile rack 2, and the driving end of the height adjustment mechanism 5 is connected to the mounting frame 20, which is used to adjust the vertical height of the conveying mechanism 4 and the receiving mechanism 3, and through the different driving amounts of the driving end of the height adjustment mechanism 5, the mounting frame 20 is tilted and rotated relative to the mobile rack 2 to adapt to the height difference between the pay-off rack 10 and the storage rack.

[0032] This solution mainly winds the cable in the pay-off frame 10 through the take-up frame 11 after the pay-off operation. Specifically, Figure 1 to Figure 2 As shown, when the pay-off frame 10 pulls the cable end to one side of the auxiliary tooling through the process operation, the cable can be pulled into the mounting frame 20 through the receiving mechanism 3. At the same time, the adjusting pulley 40 located on one side of the pay-off frame needs to be adjusted from the original initial position (i.e., at the same position as the cable inlet 110) according to the specific position of the cable inlet 110 in the take-up frame 11. Figure 2 The horizontal placement posture in the figure (not shown) is rotated relative to the mounting frame 20 to a position aligned with the wire inlet 110, so that the cable end sent by the receiving mechanism 3 can be accurately pushed into the take-up frame 11 through the adjusted conveying mechanism 4. In addition, the present solution can also realize the vertical height of the conveying mechanism 4 and the receiving mechanism 3 relative to the mobile frame 2 by adjusting the mechanism 5, and can also realize the rotation of the mounting frame 20 relative to the mobile frame 2, so as to ensure that the cable in the pay-off frame 10 is smoothly guided to the take-up frame 11 through the bearing mechanism and the conveying mechanism 4. It can be seen that the auxiliary tooling realizes the free adjustment of the transmission angle and transmission height of the cable end, effectively reducing the labor loss of manually inserting the cable end into the take-up frame 11, and improving the stability during operation and the work efficiency.

[0033] Preferably, the present invention also provides a support 7 and a cable conveyor 8 outside the mobile frame 2, such as Figure 1As shown, the bracket 7 is located on both sides of the cable conveyor 8. The cable output through the outlet 100 on the pay-off frame 10 is received by the bracket 7 and reaches the cable conveyor 8. After passing through the cable conveyor 8, it is supported by the bracket 7 again and arrives at the auxiliary tooling near the take-up frame. Therefore, the cable conveyor 8 saves manpower and material resources to a great extent. While reducing the construction cost, the bracket 7 also ensures the stability of the cable to be entered into the conveyor belt 32, thereby preventing the cable from falling and affecting the smoothness of the take-up frame 11 in the take-up process.

[0034] The conveying mechanism 4 also includes: a fixed rotating wheel 41, which is arranged on the mounting frame 20, and the fixed rotating wheel 41 is connected to the adjusting pulley 40 through a conveyor belt 42; a connecting rod 43, one end of which is hinged to the fixed rotating wheel 41, and the other end is hinged to the adjusting pulley 40 to limit the center distance between the fixed rotating wheel 41 and the adjusting pulley 40; a driving member 44, which is arranged on the mounting frame 20, and the driving end of the driving member 44 is movably hinged to the adjusting pulley 40 to push the adjusting pulley 40 to switch freely at any position between the initial position and the maximum rotation position.

[0035] like Figure 1 and Figure 2 As shown in FIG. 1 , when the wire inlet 110 in the wire take-up frame 11 is not aligned with the upper surface of the conveyor belt 42, the adjusting pulley 40 can be driven along the driving end of the driving member 44. Figure 2 The adjusting pulley 40 is displaced in the vertical direction so that it rotates relative to the fixed rotating wheel 41. When it reaches the position aligned with the cable inlet 110, the cable end can be pulled by the conveyor belt 42 and transferred to the take-up rack. It should be noted that the connecting rod 43 is used to limit the center distance between the adjusting pulley 40 and the fixed rotating wheel 41 to prevent the conveyor belt 42 from slipping and affecting the smoothness and stability of the cable end when it is pulled into the take-up rack 11. For this reason, the driving member 44 in this solution is also hinged on the mounting frame 20 to ensure that the driving end of the driving member 44 can smoothly drive the adjusting pulley 40 to the initial position (i.e. Figure 2 The conveyor belt 42 is in a horizontal position (not shown) and a maximum rotation position (i.e. Figure 2 You can switch freely between any positions between the positions shown in the figure.

[0036] Preferably, the angle between the initial position and the maximum rotation position in this solution is 45 degrees, that is, under normal operation, the adjusting pulley 40, the fixed rotating wheel 41 and the receiving mechanism 3 are in the same straight line (that is, the adjusting pulley 40 is in the initial position). When it is necessary to adjust the transmission angle of the cable end extending into the take-up frame 11, the adjusting pulley 40 can be driven by the above-mentioned driving member 44 to achieve the adjustment. Figure 2At the maximum rotation position, the maximum angle of the adjusting pulley 40 switching from the initial position to the maximum rotation position is 45 degrees, so as to ensure that the adjusting pulley 40 accurately guides the cable end.

[0037] The receiving mechanism 3 includes a driving pulley 30 and a driven pulley 31 , and a conveyor belt 32 is connected between the driving pulley 30 and the driven pulley 31 to smoothly pull the cable from the conveyor belt 32 to the conveyor belt 42 .

[0038] Similarly, if Figure 2 As shown, the active pulley 30 in this scheme is close to the above-mentioned bracket 7 and the cable conveyor 8, and the active pulley 30 is connected to a motor (not shown in the figure). Under the drive of the motor, the conveyor belt 32 can be driven to rotate through the active pulley 30 and the driven pulley 31, and finally the cable end is pulled into the conveyor belt 42. It should be noted that the above-mentioned connecting rod 43 can also be installed between the active pulley 30 and the driven pulley 31 to ensure the stability of the center distance between the two, thereby improving the smoothness of the receiving mechanism 3 when pulling the cable end.

[0039] Preferably, the mobile frame 2 in this solution is also equipped with a plurality of universal wheels 21, each of which is provided with a brake pad (not shown in the figure). When the auxiliary tooling is adjusted to the desired placement position by the universal wheel 21, the brake pad can be used to limit the rotation of the universal wheel 21, thereby ensuring the stability of the auxiliary tooling during the cable guiding process. Furthermore, a directional wheel is provided on the side of the mobile frame 2 close to the bracket 7, and two of the directional wheels and universal wheels 21 are used. The positioning wheel is used to ensure the overall stability of the auxiliary tooling, and the universal wheel 21 plays a role in the free steering of the auxiliary tooling.

[0040] The height adjustment mechanism 5 includes a main hydraulic cylinder 50 and several auxiliary hydraulic cylinders 51. The main hydraulic cylinder 50 is located at the center of the mobile frame 2, and the several auxiliary hydraulic cylinders 51 are evenly distributed at the periphery of the mobile frame 2. The driving ends of the main hydraulic cylinder 50 and the auxiliary hydraulic cylinders 51 are both connected to the mounting frame 20.

[0041] like Figure 2 As shown, the height adjustment mechanism 5 in this scheme is composed of a main hydraulic cylinder 50 and a plurality of auxiliary hydraulic cylinders 51, wherein the main hydraulic cylinder 50 is located at the center of the plurality of auxiliary hydraulic cylinders 51. Under normal operation, the main hydraulic cylinder 50 and the plurality of auxiliary hydraulic cylinders 51 synchronously drive the mounting frame 20 to move along the Figure 2The cable end coming out of the pay-off frame 10 can be at the same level as the surface of the conveyor belt 32, ensuring that the cable can be transported smoothly and stably. On the other hand, because the cable itself is relatively heavy, the main and auxiliary hydraulic cylinders 51 are driven to effectively ensure that the smoothness of cable pulling is not affected by the heavy support pressure or misoperation of the mounting frame 20. In addition, the main hydraulic cylinder 50 and several auxiliary hydraulic cylinders 51 can also achieve different driving amounts (i.e., step-type driving amounts) through different driving ends, so that the mounting frame 20 can tilt relative to the moving frame 2 under different driving amounts. In this way, when the take-up frame 11 and the pay-off frame 10 on both sides are at different heights, the transmission angles of the conveyor belt 32 and the conveyor belt 42 can be adjusted by the tilt angle of the mounting frame 20, thereby adapting to the height difference between the take-up frame 11 and the pay-off frame 10.

[0042] Preferably, a pedal 6 is also provided on the mobile frame 2 in the present embodiment. By stepping on the pedal 6 up and down, a small hydraulic device (not shown in the figure) inside the mobile frame 2 controls the height of the driving ends of the main hydraulic cylinder 50 and several auxiliary hydraulic cylinders 51 simultaneously or separately.

[0043] It should be noted that the driving member 44 in this solution can be replaced by other driving devices such as hydraulic drive, cylinder drive, etc.

[0044] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0046] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
