Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to an automatic compensation and cleaning device for a disc brake disc. Background Art

[0002] At present, most auxiliary shafts in coal mines are designed with vertical shaft landing friction hoists. Due to the use of landing friction hoists, the surface of the disc brake disc is easily affected by the water carried by the wire rope and the anti-friction grease thrown out by the wire rope, resulting in rust and pitting. At the same time, the rusty brake disc will exacerbate the wear of the brake shoes of the hoist, seriously affecting the braking torque of the hoist and reducing the hoisting safety factor.

[0003] At present, the following deficiencies exist when the disc brake disc of the hoist is in use:

[0004] 1. For the existing disc brake discs of hoists, there are potential safety hazards such as being eroded by the oil and water of the wire rope, rusting, lack of surface finish, reduction of the effective contact surface with the brake shoes of the hoist, resulting in a decrease in the braking torque of the hoist and insufficient braking force causing safety braking failure.

[0005] 2. The rust and oil stains on the surface of the brake disc damage the brake shoes, further reducing the contact area between the brake shoes and the brake disc and reducing the braking torque of the hoist. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is: how to solve the problem that the oil stains, water erosion, rust, etc. on the brake disc are not easy to clean.

[0007] To solve the above technical problem, the utility model provides the following technical solution:

[0008] An automatic compensation and cleaning device for a disc brake disc, comprising:

[0009] A sliding guide rail;

[0010] A sliding cleaning assembly, which is slidably connected to the sliding guide rail, and a cleaning member for cleaning the brake disc is detachably installed on the sliding cleaning assembly; and

[0011] A sliding guide rod, which is distributed parallel to the sliding guide rail and is connected to the sliding cleaning assembly. A sliding baffle is slidably connected outside the sliding guide rod, and a compression spring is sleeved outside the sliding guide rod between the sliding baffle and the sliding cleaning assembly; a switch alarm assembly is further provided on the sliding baffle.

[0012] In this application, the cleaning part is installed on the sliding guide rail and connected by a compression spring. The compression spring can push the cleaning part to move. When the cleaning part moves and contacts the brake disc, it can clean the dust, oil stains, and water stains on the surface of the disc brake of the disc brake. As long as the hoist is running, the cleaning device will keep working. When the cleaning material wears out, the compression spring in the device will drive the clamping device to move forward to compensate for the wear of the cleaning material, so that the cleaning material can keep close to the brake disc and continuously clean the brake disc. At the same time, this application also sets a switch alarm component. When the compensation movement of the cleaning part exceeds the range, which proves that the wear of the cleaning material is excessive, the switch alarm component can alarm to remind the user to replace it in time.

[0013] As a further solution of the utility model: The sliding cleaning component includes an upper clamping plate and a lower clamping plate. A chute for sliding connection with the sliding guide rail is opened on the lower clamping plate. The upper clamping plate is located above the lower clamping plate, and the cleaning part is located between the upper clamping plate and the lower clamping plate. The upper clamping plate, the cleaning part, and the lower clamping plate are fixed by a screw rod.

[0014] As a further solution of the utility model: The lower clamping plate is integrally in an inverted "L" shape and is detachably connected to the sliding guide rod.

[0015] As a further solution of the utility model: The cleaning part is made of hard wool felt.

[0016] As a further solution of the utility model: Two groups of sliding guide rails are symmetrically arranged. The sliding guide rail is integrally in an "L" shape. The ends of the two sliding guide rails are connected by a limit baffle, and are connected by a sliding baffle at a position slightly in the middle.

[0017] As a further solution of the utility model: The end of the sliding guide rod is provided with a thread and is slidably connected to the limit baffle. The other end passes through the sliding baffle and is connected to the sliding cleaning component.

[0018] As a further solution of the utility model: The switch alarm component includes a limit switch, a limit alarm indicator, and a switch contact block. The limit switch is installed on the sliding baffle, the limit alarm indicator is installed on the sliding guide rail, and the switch contact block is installed on the sliding guide rod. The switch contact block can contact the limit switch.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] First, in this application, the cleaning member is installed on the sliding guide rail and connected by a compression spring. The compression spring can push the cleaning member to move. When the cleaning member moves and contacts the brake disc, it can clean the dust, oil stains, and water stains on the surface of the disc brake brake disc. As long as the hoist is running, the cleaning device will keep working. When the cleaning material wears out, the compression spring in the device will drive the clamping device to move forward to compensate for the wear of the cleaning material, so that the cleaning material can keep close to the brake disc and continuously clean the brake disc;

[0021] This application relies on the adjustment function of the compression spring to compensate for the wear of the brake disc cleaning material, and there is no need for manual adjustment of the device;

[0022] Secondly, this application also sets a switch alarm component. When the movement compensation amount of the cleaning member exceeds the range, which proves that the wear of the cleaning material is excessive at this time, it will trigger the limit alarm device to send out an audible and visual alarm signal, timely reminding the maintenance and inspection personnel to carry out maintenance, improving work efficiency, and there is no need for manual assistance, saving labor costs;

[0023] Finally, this application is installed on the fixed baffle of the brake shoe, and uses a wool felt with a relatively high hardness but not damaging the surface of the disc brake brake disc to continuously clean the effective contact area between the brake disc and the brake shoe, ensuring that the brake disc remains clean and smooth, increasing the bonding surface, improving the braking torque, and ensuring the safe and reliable braking of the hoist.

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Referring to Figure 1 , Figure 2 and Figure 3 , an automatic compensation and cleaning device for a disc brake disc includes an upper clamping plate 1, a lower clamping plate 2, a sliding baffle 3, a compression spring 4, a sliding guide rod 5, a limit baffle 6, a limit nut 7, a sliding guide rail 8, a limit switch 9, a limit alarm indicator 10, a slide rail hole 11, a switch contact block 12 and a cleaning member 13;

[0031] Referring to Figure 1 , the sliding guide rail 8 is made of stainless steel angle iron and has an overall "L" - shaped structure. There are two groups symmetrically arranged. The ends of the two groups of sliding guide rails 8 are connected by a limit baffle 6. A sliding baffle 3 is installed on the front side of the two groups of sliding guide rails 8. It should be noted that both the sliding baffle 3 and the limit baffle 6 are perpendicular to the two - side sliding guide rails 8, and the sliding baffle 3 and the limit baffle 6 are parallel to each other. A lower clamping plate 2 is slidably connected to the front ends of the two sliding guide rails 8; the sliding guide rail 8 plays a role of a framework as a whole; when in use, the sliding guide rail 8 is bolt - fixed on the brake shoe support of the hoist.

[0032] It should be noted that both the limit baffle 6 and the sliding baffle 3 are made of stainless steel plates.

[0033] For the convenience of understanding and description, the end of the sliding guide rail 8 away from the lower clamping plate 2 in Figure 1 is defined as the end, and the end close to the lower clamping plate 2 is defined as the front end. The rest of the directions are analogized based on this. It should be understood that this direction setting is only for the convenience of description and understanding and should not be construed as a limitation to the present invention.

[0034] Referring to Figure 1 , the upper clamping plate 1 is made of aluminum plate and cooperates with the lower clamping plate 2 to clamp the cleaning material of the disc brake. It has a rectangular plate - like structure and is symmetrically provided with threaded holes thereon for connecting with the lower clamping plate 2.

[0035] Referring to Figure 1, the lower clamping plate 2 is made of stainless steel angle iron and cooperates with the upper clamping plate 1 to clamp and fix the cleaning material of the disc brake. The overall structure is an inverted "L" shape. Its horizontal side is arranged parallel to the upper clamping plate 1, and threaded holes are also opened on it to connect the upper clamping plate 1; symmetrically arranged guide rail chutes are opened on its vertical side to slidably connect with two groups of sliding guide rails 8. Therefore, it can be clearly seen that the lower clamping plate 2 of the present application can slide along the sliding guide rail 8.

[0036] Furthermore, a cleaning member 13 is provided between the top of the lower clamping plate 2 and the upper clamping plate 1. One end of the cleaning member 13 away from the sliding guide rail 8 is convexly designed. When it touches the brake disc, the cleaning member 13 touches the brake disc earlier than the upper clamping plate 1 and the lower clamping plate 2; at the same time, it should be noted that the cleaning member 13 of the present application is made of wool felt with higher hardness to ensure that it can better clean the brake disc.

[0037] Refer to Figure 1 , two sliding holes are symmetrically opened on the sliding baffle 3, and two sliding guide rods 5 can pass through the sliding holes.

[0038] Refer to Figure 1 and Figure 3 , the compression spring 4 is sleeved on the sliding guide rod 5 between the lower clamping plate 1 and the sliding baffle 3. When in use, the compression spring 4 can push the lower clamping plate 2 to slide forward along the sliding guide rail 8. At the same time, the lower clamping plate 2 drives the sliding guide rod 5 to move forward, so as to realize that the lower clamping plate 2 drives the wool felt to closely adhere to the brake disc.

[0039] Refer to Figure 1 , the sliding guide rod 5 is a double-headed stainless steel bolt. Its front end is screwed to the lower clamping plate 2, passes through the sliding baffle 3 and the limit baffle 6 in the middle, and a limit nut 7 is arranged at the end, which can play a positioning role when not in use.

[0040] Refer to Figure 1 , the model of the limit switch 9 is selected as model V-154-1C25, a single-node micro-motion limit switch. When the micro-motion switch acts, it triggers the limit alarm indicator to work. It is installed on the sliding baffle 3, and the switch contact block 12 is installed on the sliding guide rod 5 close to the limit switch 9. Among them, the switch contact block 12 can contact the limit switch 9; the limit alarm indicator 10 is fixed on the outside of the sliding guide rail 8, and the normally open contact of the limit switch 9 is connected in series to the power supply circuit of the limit alarm indicator 10; when the cleaning material wears out beyond the limit, that is, when the lower clamping plate 2 moves forward about 20 mm, at this time the limit switch 9 contacts the switch contact block 12, and the normally open contact of the limit switch 9 closes, connecting the power supply of the limit alarm device 10 and driving the alarm to send out an audible and visual alarm signal, timely reminding the maintenance and inspection personnel to carry out maintenance and improving work efficiency.

[0041] The specific operation principle of the present application is as follows:

[0042] When in use, fix the disc brake cleaning device of the present application on the support of the disc brake braking shoe. Under the action of the compression spring 4, the cleaning member 13 is closely attached to the surface of the brake disc. When the hoist is running, it cleans the dust, oil stains and water stains on the surface of the brake disc. If the cleaning member 13 is worn, the compression spring 4 will drive the clamping plate to drive the cleaning member 13 (the compression spring 4 is in a compressed state when the normal cleaning member 13 contacts the brake disc, and generates a pressure of about 0.05 Bar on the brake disc) to move forward to compensate for the wear amount. When the wear of the cleaning member 13 exceeds the limit, the normally open contact of the limit switch 9 closes, turning on the power supply of the limit alarm device and driving the alarm to emit an audible and visual alarm signal.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
