Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically to a clamping mechanism for a wire winding machine. Background Technology

[0002] A wire winding machine is a piece of equipment used in suspension bridge construction to wrap the main cable. Before winding, the main cable is usually clamped by a clamping mechanism located in front of the winding machine in the direction of travel to improve winding efficiency and effectiveness. Currently, the clamping mechanisms of wire winding machines mainly include manual screw clamping or double hydraulic jack clamping. Manual screw clamping mechanisms have insufficient clamping force, while double hydraulic jack clamping uses a large number of jacks, resulting in higher costs. Summary of the Invention

[0003] The purpose of this invention is to provide a single-cylinder wire winding machine clamping mechanism with a compact structure and good stability.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is: a wire winding machine clamping mechanism, including an installation assembly, a jack clamping assembly, and a clamping roller assembly;

[0005] The mounting assembly includes a mounting plate, with a hinge seat on the upper part of one side of the mounting plate and two vertical positioning sleeves on both sides of the middle part.

[0006] The clamping roller assembly includes a clamping seat and nylon clamping rollers disposed at the bottom of the clamping seat;

[0007] The jack clamping assembly includes a hydraulic jack and two support rods disposed on both sides of the hydraulic jack; the upper end of the support rod passes through the positioning sleeve and the lower end is connected to the clamping seat; the upper end of the hydraulic jack is pinned to the hinge seat and the lower end is pinned to the clamping seat.

[0008] Preferably, the top of the clamping seat is divided into multiple hinge areas by several partitions, and the lower end of the support rod and the hydraulic jack is provided with a rod head. The rod head is inserted into the hinge area and forms a pin connection with the clamping seat through a seat pin arranged in the transverse direction.

[0009] The lower section of the support rod is also provided with a threaded section, and the threaded section is fitted with an anti-rotation spacer and an anti-rotation nut that form a threaded engagement with it.

[0010] Preferably, the lower part of the clamping seat extends downward to form two lugs, and the nylon clamping wheel is located between the lugs and is pinned to the clamping seat by a wheel pin extending laterally.

[0011] Preferably, a back pressure plate is provided on the rear side of the clamping seat.

[0012] Preferably, the upper ends of the support rods are connected by a connecting strip.

[0013] Preferably, two pairs of short plates distributed vertically are welded to both sides of the mounting plate opposite to the positioning sleeve. The ends of the short plates are provided with arc-shaped notches, and the positioning sleeve is installed in the arc-shaped notches and welded to the short plates.

[0014] The beneficial effects of this invention are mainly reflected in the following aspects: The use of a single hydraulic jack simplifies the overall structure, and the guidance of the support rod by the positioning sleeve improves overall stability and clamping directionality, ensuring stable clamping of designated parts. Specifically, during use, the hydraulic jack extends and retracts, driving the clamping seat and the nylon clamping wheel mounted on it to clamp the main cable, providing a stable clamping force. The support rod slides within the positioning sleeve, and the guidance of the positioning sleeve makes the movement of the support rod more stable, ensuring better directionality of the clamping seat and nylon clamping wheel during clamping. Through structural optimization, this invention simplifies the structure of the clamping mechanism of the winding machine, reducing overall production costs while ensuring clamping effectiveness.

[0018] Figure 4 for Figure 3 The left view. Detailed Implementation

[0019] like Figure 1-4 As shown, a clamping mechanism for a wire winding machine is a pre-clamping mechanism that can pre-clamp the main cable before winding to ensure the winding effect. Figure 1 As shown, this utility model includes, from top to bottom, an installation assembly, a jack clamping assembly, and a clamping roller assembly. The installation assembly is used to connect to the main frame of the wire winding machine, the clamping roller assembly is used to clamp the main cable, and the jack clamping assembly is used to connect the two and provide clamping pressure.

[0020] like Figure 1As shown, the mounting assembly includes a mounting plate 1. A hinge seat 2 is provided on the upper part of one side of the mounting plate 1, and two vertical positioning sleeves 3 are provided on both sides of the middle part. The mounting plate 1 has connecting bolt holes, and multiple pairs of connecting bolt holes can be provided. By adjusting its connection position with the main frame of the winding machine, it can adapt to the tightening requirements of different sizes of cables. The positioning sleeves 3, as important guiding components, are designed to improve the connection strength between themselves and the mounting plate 1. Figure 2 As shown, the present invention can weld two or more pairs of vertically distributed short plates 16 on both sides of the opposite side of the mounting plate 1 and the positioning sleeve 3. The ends of the short plates 16 are provided with arc-shaped notches, and the positioning sleeve 3 is installed in the arc-shaped notches and welded to the short plates 16.

[0021] The clamping roller assembly described in this utility model patent is a component for direct contact with the main cable, comprising a clamping seat 4 and nylon clamping wheels 5 disposed at the bottom of the clamping seat 4. To facilitate connection and assembly, and to allow flexible switching between plate pressure and wheel pressure, a back pressure plate 14 is provided on the rear side of the clamping seat 4. The back pressure plate 14 and the nylon clamping wheels 5 are generally distributed at a 90-degree angle, enabling flexible switching. Specifically, the top of the clamping seat 4 can be divided into multiple hinge areas by several partitions 7. The lower ends of the support rod 6 and the hydraulic jack 100 are provided with rod heads 8, which are inserted into the hinge areas and connected to the clamping seat 4 via transversely arranged seat pins 9.

[0022] like Figure 1 and 2 As shown, the jack clamping assembly includes a hydraulic jack 100 and two support rods 6 disposed on both sides of the hydraulic jack 100. The two ends of the hydraulic jack 100 are interchangeable, meaning the cylinder end and the telescopic end can be reversed without affecting normal use. Figure 1 and 2 The middle section is where the cylinder block is located at the bottom, while Figure 3 and 4 The middle cylinder is located at the top. The upper end of the support rod 6 passes through the positioning sleeve 3, and the lower end is connected to the clamping seat 4. The upper and lower ends can also be connected by a connecting strip 15 to improve stability. The upper end of the hydraulic jack 100 is pinned to the hinge seat 2, and the lower end is pinned to the clamping seat 4. There are many specific forms of pin connection, among which the form described above is the most compact and reasonable.

[0023] Of course, since the support rod 6, hydraulic jack 100, and clamping seat 4 are connected by pins, to ensure stability and prevent rotation when switching between plate pressure and wheel pressure, a better approach is to provide a threaded section 0 on the lower part of the support rod 6. An anti-rotation spacer 10 and an anti-rotation nut 11 are fitted onto the threaded section 0 to form a threaded engagement. By adjusting the anti-rotation spacer 10 and anti-rotation nut 11 until they are in full contact with the clamping seat 4, the angle of the clamping seat 4 can be controlled through the anti-rotation spacer 10 and anti-rotation nut 11, thus achieving the switching adjustment between plate pressure and wheel pressure.

[0024] Regarding the installation of the nylon clamping wheel 5, this invention can extend downwards from the lower part of the clamping seat 4 to form two wheel ears 12. The nylon clamping wheel 5 is located between the wheel ears 12 and is pinned to the clamping seat 4 through a wheel pin 13 extending laterally. The back pressure plate 14 can be directly connected and fixed by cross-shaped horizontal and vertical ribs.
