Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of disc brakes, and particularly relates to a convenient disassembly type disc brake for a shaft hoist. Background Technique
[0002] The disc brake adopted by the shaft hoist is a new type of high-performance brake and is the development direction of the current mechanical brake. It has the following advantages: small volume, light weight, small inertia, fast action, good adjustable performance, high reliability, high versatility, and simple structure. The disc brake can be used in various machinery such as mine hoists, belt conveyors, aerial ropeways, ship lifts, etc. The disc brake is used for working brake and emergency brake on the mine hoist, and its drive and control are completed by a separate hydraulic station.
[0003] Since the disc brake is extremely important for the safety of shaft hoisting, some existing disc brakes have rust failures, resulting in the inability to normally adjust the distance between the brake pads and the drum brake disc, often causing alarms due to excessive distance.
[0004] Moreover, since the rusted part is the hydraulic component part of the disc brake, when repairing the hydraulic components of the disc brake, the hydraulic station is required to drive the disc brake under pressure to overcome the elastic force of the internal spring of the disc brake so that the two clamping discs are separated. The disc brake and the hydraulic station are fixedly connected by a straight pipe. Limited by the on-site space during maintenance, it is difficult to repair by conventional means, the maintenance time is long, the replacement cost is high, and at the same time, the coordination operation problem with the machine room operator during the maintenance process also needs to be solved.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0028] As Figure 1 And Figure 2 Shown, the present utility model provides a convenient disassembly type shaft hoist disc brake, including:
[0029] Disc brake body 1, and a hydraulic input pipe 101 is hermetically connected to the oil inlet of the hydraulic component of the disc brake body 1.
[0030] Mobile hydraulic press 2, and a hydraulic output pipe 201 is connected to the output end of the mobile hydraulic press 2.
[0031] Stop valve 3, the hydraulic input pipe 101 and the hydraulic output pipe 201 are connected through the stop valve 3, and the valve pipe 301 of the stop valve 3 and the hydraulic input pipe 101 and the hydraulic output pipe 201 are detachably installed.
[0032] In this embodiment, a hydraulic input pipe 101 is connected to the oil inlet of the disc brake body 1, and the hydraulic input pipe 101 is detachably connected to the external hydraulic station. When overhauling the hydraulic component of the disc brake body 1, the hydraulic station is closed and the connection between the hydraulic input pipe 101 and the hydraulic station is cut off.
[0033] After that, the hydraulic input pipe 101 is connected to the mobile hydraulic press 2 through the stop valve 3, and the mobile hydraulic press 2 is used to apply pressure to the hydraulic components of the disc brake body 1 so that the two chucks of the disc brake body 1 are separated, thereby overhauling the hydraulic components and the chucks.
[0034] Finally, the hydraulic input pipe 101 is closed through the stop valve 3, so that the stop valve 3 can be separated from the mobile hydraulic press 2, which is convenient for the mobile overhaul of the disc brake body 1 and also avoids affecting the hydraulic station.
[0035] In this embodiment,
[0036] The stop valve 3 is composed of a spherical stop valve, a ball valve joint, a metal flat washer, and a reducing connector.
[0037] Among them, the spherical stop valve is installed on the valve pipe 301 through the ball valve joint. The two ends of the valve pipe 301 are connected with a reducing connector and a metal flat washer, and the two ends of the valve pipe 301 are detachably and sealingly connected to the hydraulic input pipe 101 and the hydraulic output pipe 201.
[0038] In this embodiment, referring to Figure 2 As shown, a sealing assembly 4 is provided between the valve pipe 301 and the hydraulic input pipe 101 and the hydraulic output pipe 201 to enable a sealed connection between the valve pipe 301 and the hydraulic input pipe 101 and the hydraulic output pipe 201.
[0039] In order to further improve the sealing performance of the connection between the valve pipe 301 and the hydraulic input pipe 101 and the hydraulic output pipe 201, referring to Figure 3 As shown, in this embodiment, the sealing assembly 4 includes a fixing ring 401 fixedly sleeved on the valve pipe 301. An annular clamping groove 402 is formed on the inner wall of the fixing ring 401. The annular clamping groove 402 is in sliding contact with the hydraulic input pipe 101 and the hydraulic output pipe 201. A sealing member is provided in the annular clamping groove 402, and the sealing member abuts against the circumferential walls of the hydraulic input pipe 101 and the hydraulic output pipe 201.
[0040] In order to achieve the sealing effect of the sealing member between the annular clamping groove 402 and the hydraulic input pipe 101 and the hydraulic output pipe 201, in this embodiment, the sealing member includes an annular mounting groove 403 formed on the annular clamping groove 402. An annular expansion airbag 404 is provided in the annular mounting groove 403, and the expansion airbag 404 is connected to a pressure mechanism through a connecting pipe.
[0041] When the valve pipe 301 is connected to the hydraulic input pipe 101 and the hydraulic output pipe 201, an external pressure mechanism is used to inflate or fill hydraulic oil into the expansion airbag 404, so that the expansion airbag 404 expands. After the expansion airbag 404 expands, it abuts against the peripheral walls of the hydraulic input pipe 101 and the hydraulic output pipe 201, thereby making the inner wall of the annular card slot 402 abut against the peripheral walls of the hydraulic input pipe 101 and the hydraulic output pipe 201, so that the annular card slot 402 is hermetically connected to the hydraulic input pipe 101 and the hydraulic output pipe 201.
[0042] In this embodiment, a pressure sensor is installed on the fixed ring 401, and the monitoring end of the pressure sensor is arranged inside the expansion airbag 404, so that the pressure sensor can monitor the internal pressure state of the expansion airbag 404 in real time.
[0043] When pressurizing the inside of the expansion airbag 404 through a pressure mechanism to drive its expansion, the internal pressure of the expansion airbag 404 can be monitored in real time through the pressure sensor, so as to avoid damage to the expansion airbag 404 caused by excessive internal pressure of the expansion airbag 404. At the same time, during the process of closing the stop valve 3 and overhauling the disc brake body 1, the pressure state of the pressure sensor can also be observed in real time to understand the connection sealing performance between the valve pipe 301 and the hydraulic input pipe 101.
[0044] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
