Description

Technical Field

[0001] The utility model relates to the technical field of rope supporting wheels, in particular to a balanced rope supporting wheel. Background Art

[0002] The rope support pulley is an important component of the endless rope winch system in underground coal mines. It is installed in the middle of the track and is suitable for high points in the tunnel. It supports the wire rope to avoid wear on sleepers and other parts of the track. In practical applications, a set of rope support pulleys is usually installed every 15 meters. However, in the actual track terrain, some track sections have excessive ups and downs and steep slopes. In this terrain, conventional rope support pulleys cannot ensure the appropriate distance between the wire rope and the sleeper, and there will still be problems with the wire rope grinding on the sleeper.

[0003] In view of this, a design or technical improvement is now proposed to solve the above problems.

[0004] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned shortcomings and provide a balanced rope supporting wheel.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A balanced rope supporting wheel comprises a mounting base, a base plate is arranged on the mounting base, two groups of wheel bodies movable up and down and an adjusting assembly for adjusting the height of the wheel bodies are arranged on the base plate;

[0008] The adjusting assembly comprises a bolt rod connected with the frame bearing of the base plate and two groups of supporting frames which are limitedly slidable between the two groups of frame plates and are located at the lower end of the wheel body.

[0009] Furthermore, the base plate includes a frame body and two sets of frame plates arranged inside the frame body, a gap is arranged between the two sets of frame plates, and a limiting slide for limiting the wheel body is arranged on the frame plate.

[0010] Furthermore, support frames are arranged on both sides of the wheel body, and the support frames include a movable clamping plate connected to the wheel body bearing and an overhanging block that slides in a limited position in a limited slide.

[0011] Furthermore, the support frame includes a limiting portion that is clamped and slides between the two sets of frame plates, and side arms that are arranged on both sides of the limiting portion and slide in contact with the upper surface of the frame plates.

[0012] Furthermore, the bolt rod is threadedly connected to the limiting portion, an arcuate surface is provided on the lower side of the movable clamping plate of the support frame, and a wedge-shaped surface that movably abuts against the arcuate surface of the movable clamping plate is provided on the side of the side arm opposite to the movable clamping plate.

[0013] Compared with the prior art, the beneficial effects of the present scheme are as follows: the rope support wheels designed in the present scheme, through the parallel arrangement of two groups of rope support wheels, firstly enhance the friction between the wire rope and the wheel body, thereby reducing the displacement of the wheel body during the movement, and at the same time the height of the wheel body is adjustable, so that when encountering some steeper and undulating track sections, the height of the wheel body can be adjusted to keep the wire rope and the sleeper at an appropriate distance, thereby improving the durability of the wire rope.

[0021] The following will be combined with 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] like Figure 1-5 The balanced rope supporting wheel shown in the figure comprises a mounting base 1, on which a base plate 11 is arranged, on which two groups of wheel bodies 12 which can move up and down and an adjusting assembly for adjusting the height of the wheel body 12 are arranged. The device is installed in the middle of the track by means of the mounting base 1 in conjunction with bolts, and then a steel wire rope is erected on the upper end of the wheel body 12 to form a support for the rope body. When a part of the steel wire rope section is in a position with large terrain undulations, the height of the wheel body 12 is adjusted by the adjusting assembly so that this section of the rope body is additionally elevated, thereby avoiding the problem of pillow grinding. The arrangement of the two groups of wheel bodies 12 also ensures that the angle formed by the supporting point of the steel wire rope when it encounters a position with large undulations after erection will not be too small, thereby reducing the resistance between the rope body and the wheel body 12 and reducing the possibility of steel wire rope breakage.

[0023] In one embodiment, the base plate 11 includes a frame body 2 and two groups of frame plates 21 arranged on the inner side of the frame body 2, a gap is arranged between the two groups of frame plates 21, a limiting slide 22 for limiting the wheel body 12 is arranged on the frame plate 21, and support frames 3 are arranged on both sides of the wheel body 12. The support frame 3 includes a movable clamping plate 31 connected to the bearing of the wheel body 12 and an overhanging block 32 that slides in the limiting slide 22. The two ends of the wheel body 12 are clamped between the overhanging block 32 and the limiting slide 22, thereby limiting the wheel body 12 so that it can only move up and down. At the same time, the wheel body 12 and the movable clamping plate 31 are connected in a bearing-like manner to ensure that the wheel body 12 can rotate freely.

[0024] In one embodiment, the adjusting assembly includes a bolt rod 4 connected to the bearing of the frame 2 of the base plate 11 and two groups of support frames 41 that slide in a limited position between the two groups of frame plates 21 and are located at the lower end of the wheel body 12. The support frame 41 includes a limiting portion 42 that is clamped and slides between the two groups of frame plates 21 and side arms 43 that are arranged on both sides of the limiting portion 42 and slide in contact with the upper surface of the frame plate 21. The bolt rod 4 is threadedly connected to the limiting portion 42, and an arc surface is provided on the lower side of the movable clamping plate 31 of the support frame 3. A wedge surface that movably engages with the arc surface of the movable clamping plate 31 is provided on the side of the side arm 43 opposite to the movable clamping plate 31. The device allows the support frame 41 to slide in a limited position on the base plate 11 by rotating the bolt rod 4. When the support frame 41 slides, the wedge surface on its side arm 43 engages with the arc surface on the lower side of the movable clamping plate 31, thereby pushing the wheel body 12 to move upward, thereby achieving the effect of adjusting the height of the rope of the wheel body 12.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
