Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically to a rope changing machine car drum support wheel. Background Technology

[0002] Currently, the hoisting system of the Wangcun auxiliary shaft in our mine has four head ropes. In the head rope replacement process, to ensure that the old and new wire ropes and their connecting rope clamps can pass smoothly through the drum without the hoist rotating, we adopted a solution of installing support wheels on the drum. This solution relies on the rotation of about 90 support wheels to support and guide the wire rope. However, in the current operation, the support wheels are quite heavy, and the installation method involves pre-drilling threaded holes on the drum and then fixing it with screws. This installation method is cumbersome and requires drilling holes on the drum, resulting in low work efficiency and seriously affecting the overall progress of the rope replacement work. According to statistics, the installation and removal of each set of support wheels takes about 3 hours, resulting in a very high total time cost. Utility Model Content

[0003] The purpose of this utility model is to provide a support wheel for the rope changing workshop drum, so as to solve the problem that the roller is relatively heavy during the process of changing the first rope. The installation of the roller on the hoist drum by pre-drilling threaded holes and screws is complicated and time-consuming, which affects the progress of the rope changing operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rope changing machine drum support wheel, comprising a support wheel, a mounting plate, and a track frame. Mounting plates are connected to the left and right ends of the support wheel, and each mounting plate has a mounting groove at the end away from the support wheel, which cooperates with the convex plate on the track frame. The track frame is composed of a first track frame and a second track frame. The first track frame has a U-shaped frame at the end away from the connection with the mounting plate. The second track frame has a groove on one side of the U-shaped frame, and an H-shaped frame is connected to the end of the groove. The horizontal end of the H-shaped frame and the inner walls of the upper and lower sides of the groove form an installation space for the upper and lower horizontal ends of the U-shaped frame to be inserted. A guide rod is provided between the horizontal end of the H-shaped frame and the inner wall of the groove. One end of the guide rod is connected to the inner wall of the groove, and the other end passes through the vertical end of the U-shaped frame and is connected to the horizontal end of the H-shaped frame. A spring is sleeved on the guide rod. One end of the spring abuts against the vertical end of the U-shaped frame, and the other end abuts against the inner wall of the groove.

[0005] Preferably, it also includes auxiliary devices, respectively disposed at the front and rear ends of the first track frame, including a mounting shell, an offset frame, a first pressure rod, a second pressure rod, and a sliding rod. The mounting shell is a rectangular hollow shell, with the offset frame hinged inside. The offset frame is L-shaped, with the second pressure rod connected to its bottom horizontal end and a sliding rod disposed at its top horizontal end. The top of the sliding rod penetrates the mounting shell and is connected to a limit ring. The vertical end of the offset frame is horizontally connected to an extension portion at the end facing the mounting plate. A first pressure rod is provided at the bottom end of the extension portion. A gap is preset between the first pressure rod and the extension portion, forming an installation space for fixing blocks that can be symmetrically arranged on the front and rear ends of the mounting plate.

[0006] Preferably, the top end of the extension of the offset frame is inclined to allow the fixing block to slide in.

[0007] Preferably, the first pressure rod and the second pressure rod are composed of a telescopic rod and a return spring. Limiting rings are respectively provided on the upper and lower ends of the telescopic rod, and the return spring is sleeved on the telescopic rod, with its two ends respectively abutting against the limiting rings.

[0008] Preferably, the bottom ends of the first and second track frames away from the corresponding end faces are provided with grooves that match the shape of the external track, so that the track frames can be stably fastened to the track.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The first and second track frames, along with the springs on the guide rods, enable quick installation and disassembly, and ensure that the track frames are stably fastened to the track.

[0010] The track frame uses grooves and auxiliary devices to enable quick installation of support wheels, allowing for repair and replacement of damaged individual support wheels without requiring complete disassembly and scrapping. Attached Figure Description

[0019] 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.

[0020] Example 1: Please refer to Figure 1-2 This utility model provides an embodiment of a rope-changing workshop roller support wheel, including a support wheel 1 that directly supports and guides the rotation of new and old steel wire ropes, transforming the sliding friction between the steel wire rope and the drum into the rolling friction of the support wheel 1 itself, greatly reducing traction force; a mounting plate 2; and a track frame. Mounting plates 2 are connected to the left and right ends of the support wheel 1, respectively, to transmit the force received by the support wheel 1 to the track frame. Each mounting plate 2 has a mounting groove at the end away from the support wheel 1, which cooperates with the convex plate on the track frame. The track frame consists of a first track frame 3, which serves as a connector between the support wheel 1 and the mounting plate 2, and is connected to a second track frame 5 via a U-shaped frame. It can slide under the action of a spring and is fixed to the track by two bottom grooves. The second track frame 5 is composed of the first track frame 3 and the second track frame 5. The bottom end of the first track frame 3 and the second track frame 5 away from the corresponding end face has a groove that matches the shape of the external track, so that the track frame can be stably fastened to the track. The first track frame 3 has a U-shaped frame at the end away from the connection with the mounting plate 2. The second track frame 5 has a groove on one side of the U-shaped frame and is fixed to the external track by the bottom groove. The internal H-shaped frame and the groove form a guide for the first track frame 3, allowing the first track frame 3 to slide along the space formed by the H-shaped frame and the groove, while changing the distance between the first track frame 3 and the second track frame 5, which can satisfy the needs of the track frame. The track frame is designed for installation on tracks of varying widths. An H-shaped frame is connected to the end of the groove. The horizontal end of the H-shaped frame and the inner walls of the upper and lower sides of the groove form an installation space for the horizontal ends of the U-shaped frame. A guide rod 6 is installed between the horizontal end of the H-shaped frame and the inner wall of the groove to ensure that the U-shaped frame of the first track frame 3 can only slide smoothly in a straight line, preventing it from tilting, jamming, or twisting. One end of the guide rod 6 is connected to the inner wall of the groove, and the other end passes through the vertical end of the U-shaped frame and connects to the horizontal end of the H-shaped frame. A spring is fitted onto the guide rod 6. In the initial position, the spring supports the increase in the distance between the first track frame 3 and the second track frame 5. During installation, the spring is simultaneously compressed by squeezing the distance between the first track frame 3 and the second track frame 5, placing the track frame between the tracks. Then, the spring is released, and the compressed spring drives the second track frame 5 and the first track frame 3 to return to their original positions. At the same time, the grooves at the bottom of the first track frame 3 and the second track frame 5 engage with the tracks, completing the installation. One end of the spring abuts against the vertical end of the U-shaped frame, and the other end abuts against the inner wall of the groove.

[0021] Example 2: Please refer to Figure 1 , 3 Based on Example 1, it also has the following structure: It also includes an auxiliary device 4 to lock or release the fixing block 201 on the mounting plate 2 to prevent the support wheel 1 from accidentally jumping off the track under vibration or impact. This device is located on the front and rear ends of the first track frame 3 and includes a mounting shell, an offset frame 401, a first pressure rod 402, and a second pressure rod 403. The first and second pressure rods 402 and 403 are composed of telescopic rods and return springs. Limit rings are provided at the upper and lower ends of the telescopic rods, and the return springs are sleeved on the telescopic rods, with their ends contacting the limit rings. A sliding rod 404 is also included. The mounting shell is a rectangular hollow shell used to fix and accommodate all components. The mounting shell is L-shaped, with the top providing space for the fixing block 201. The offset frame 401 is hinged inside, with the hinge point being the connection between the horizontal and vertical ends. The offset frame 401 is L-shaped. The bottom of its horizontal end is connected to a second pressure rod 403, which supports the horizontal end of the offset frame 401. When unlocking, pressing the slide rod 404 presses down the horizontal end of the offset frame 401, simultaneously displacing the slide rod of the telescopic rod inside the second pressure rod 403, and simultaneously squeezing the return spring, thereby rotating and offsetting the offset frame 401, causing the extension part to shift, thus unlocking and sliding out the fixing block 201. The top of the horizontal end is provided with a slide rod 404, and there is a gap between the slide rod 404 and the vertical end of the offset frame 401. This gap is sufficient to allow the fixing block 201 to slide out after the offset frame 401 rotates and shifts. The top of the slide rod 404 penetrates the mounting shell and is connected to a limit ring, which is used to press the offset frame 401 for forced unlocking. The limit ring on it prevents the slide rod 404 from completely detaching from the mounting shell. The vertical end of the offset bracket 401, facing the mounting plate 2, is horizontally connected to an extension. A first pressure rod 402 is located at the bottom of the extension. A gap is pre-set between the first pressure rod 402 and the extension, creating an installation space for the fixing blocks 201 symmetrically arranged on the front and rear sides of the mounting plate 2. After the fixing block 201 slides in, one end abuts against the horizontal end of the bottom of the extension, and the other end abuts against the limiting ring at the top of the first pressure rod 402. The top of the extension of the offset bracket 401 is inclined to allow the fixing block 201 to slide in. At the same time, the mounting slot on the mounting plate 2 is installed in conjunction with the convex plate of the first track frame 3. Simultaneously, the bottom end of the mounting plate 2 is placed on the placement platform on the first track frame 3, and the fixing block 201 slides against the inclined surface of the extension part. At the same time, the offset frame 401 is rotated. At this time, the sliding rod inside the telescopic rod of the second pressure rod 403 is pressed, and the return spring is compressed simultaneously. When the fixing block 201 slides in, the return spring drives the limiting ring on the sliding rod inside the telescopic rod to return to its original position, and at the same time, the offset frame 401 is driven to return to its original position, thus limiting the fixing block 201.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
