Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic tensioning devices, specifically relating to a hydraulic tensioning device for a top-loading coke pusher coal leveling device. Background Technology

[0002] The coal leveling device is an important component of the top-loading coke pusher. It uses pulleys to drive a wire rope, which pulls the leveling rod into the carbonization chamber for leveling operations. In existing technology, the tensioning of the wire rope typically relies on manual adjustment. This process is not only time-consuming and labor-intensive, but also makes it difficult to guarantee the accuracy and consistency of the tension. Especially in situations requiring frequent adjustments or high tension, the traditional manual adjustment method is particularly inadequate.

[0003] Specifically, traditional manual adjustment of wire tension typically requires stretching or compressing the wire using hand tools or mechanical devices to achieve the desired tension. However, this method has several drawbacks. First, manual adjustment requires operators with a high level of skill and experience; otherwise, it is difficult to accurately control the tension, leading to the wire being too tight or too loose, affecting its performance. Second, the manual adjustment process is cumbersome, requiring significant time and effort, thus reducing work efficiency. Finally, under prolonged or high-intensity working conditions, operators are prone to fatigue, further impacting the accuracy and reliability of the tensioning operation. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic tensioning device for the coal leveling device of a top-loading coke pusher, aiming to solve the problem that the tensioning operation of steel wire usually relies on manual adjustment. This process is not only time-consuming and labor-intensive, but also makes it difficult to ensure the accuracy and consistency of the tension. Especially in situations requiring frequent adjustments or high tension, the traditional manual adjustment method is particularly inadequate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic adjustment and tensioning device for a top-mounted coke pusher coal leveling device, comprising a top-mounted coke pusher frame, a coal leveler installed near the upper part of the top-mounted coke pusher frame, and steel wires installed on the side of the coal leveler;

[0006] The other end of the steel wire is connected to a pulley, which is installed in the center of the pulley frame. Two guide wheels are installed on both sides of the pulley frame, and the guide wheels are movably installed in the track. The other side of the track is installed on the inner wall of the top-mounted coke pusher. One end of the pulley frame is connected to a hydraulic cylinder.

[0007] In order to enable the hydraulic cylinder to drive the pulley frame to move when it extends and retracts, so that the pulley frame can tighten the steel wire through the pulley, as a preferred hydraulic adjustment and tensioning device of the top-mounted coke pushing car coal leveling device of this utility model, one end of the hydraulic cylinder is equipped with a connector and the other end of the hydraulic cylinder is equipped with a support.

[0008] One end of the connector is mounted on the pulley frame, and the oil cylinder is fixedly connected to the pulley frame through the connector.

[0009] In order to enable the hydraulic cylinder to be effectively positioned between the guide rail and the top-mounted coke pusher frame, as a preferred embodiment of the hydraulic adjustment and tensioning device of the top-mounted coke pusher car coal leveling device of this utility model, the support is mounted on the mounting plate, the mounting plate is mounted on the frame of the top-mounted coke pusher frame, and the other side of the hydraulic cylinder is fixed to the frame of the top-mounted coke pusher frame through the support.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] When tensioning of the steel wire is required, the hydraulic cylinder is activated. When the hydraulic cylinder is working, it pushes the pulley frame to move through the telescopic end. The pulley frame drives the guide wheels on both sides to move along the corresponding track. In this way, the pulley frame drives the pulley to move, and the movement of the pulley will tighten the steel wire. Thus, in actual use, the tension of the steel wire can be adjusted hydraulically in this way, which is more time-saving and labor-saving than the traditional manual adjustment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2 The present invention provides the following technical solution: a hydraulic adjustment and tensioning device for a top-mounted coke pusher leveling device, including a top-mounted coke pusher 1, a leveling device 2 installed near the upper part of the top-mounted coke pusher 1, and a steel wire 3 installed on the side of the leveling device 2.

[0018] The other end of the steel wire 3 is connected to the pulley 4. The pulley 4 is installed in the center of the pulley frame 5. Two guide wheels 6 are installed on both sides of the pulley frame 5. The guide wheels 6 are movably installed in the track 7. The other side of the track 7 is installed on the inner wall of the top-mounted coke pusher 1. One end of the pulley frame 5 is connected to the oil cylinder 9.

[0019] The hydraulic system used in cylinder 9 comes from the hydraulic system of the coke pusher car.

[0020] Preferably, a connector 8 is installed at one end of the hydraulic cylinder 9, and a support 10 is installed at the other end of the hydraulic cylinder 9;

[0021] One end of the connector 8 is mounted on the pulley frame 5, and the oil cylinder 9 is fixedly connected to the pulley frame 5 through the connector 8.

[0022] Preferably, the support 10 is mounted on the mounting plate 11, the mounting plate 11 is mounted on the frame of the top-mounted coke pusher 1, and the oil cylinder 9 is fixed on the other side of the top-mounted coke pusher 1 via the support 10.

[0023] Working principle: When tensioning of the steel wire 3 is required, this technical solution provides a hydraulic drive scheme. The hydraulic cylinder 9 is activated, and its extension / retraction end begins to work. The extension / retraction end of the hydraulic cylinder 9 pushes the pulley frame 5 to move smoothly.

[0024] Meanwhile, the guide wheel 6 of the pulley frame 5 moves along the corresponding track 7 without deviating from its direction. Driven by the pulley frame 5, the pulley 4 also begins to move. As a component connected to the steel wire 3, the position of the pulley 4 affects the tension of the steel wire 3. As the pulley 4 moves, it gradually tightens the steel wire 3, tautling the originally slack steel wire 3 little by little.

[0025] This method, which uses hydraulic drive and pulley frame 5 to move pulley 4, achieves the adjustment of the tension of the steel wire 3. Compared with the traditional manual adjustment method, this hydraulic adjustment method is not only more time-saving and labor-saving, but also greatly improves the accuracy and efficiency of tensioning operation. In actual use, the operator only needs to simply control the start and stop of the hydraulic cylinder 9 to easily achieve precise adjustment of the tension of the steel wire 3, meeting the needs of various complex working conditions.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
