Description

Technical Field

[0001] This utility model relates to the field of petroleum engineering machinery, and in particular to a forced air-cooled disc brake control system. Background Technology

[0002] Currently, disc brake systems generally employ three methods to address heat dissipation for the brake discs and calipers: ① Solid discs, relying on natural heat dissipation; ② Air-cooled discs, with ventilation channels on the brake disc, relying on rotation or natural heat dissipation; ③ Water-cooled discs, with built-in water flow channels, forming a closed circulation system that dissipates heat by carrying it away with flowing water. However, most current brake-equipped devices use protective covers on the brake discs to prevent mechanical damage and rain corrosion. These covers are typically made of bent sheet metal, almost completely enclosing the brake actuator and effectively isolating airflow. Even with these protective covers, the heat dissipation of solid and air-cooled discs is not ideal, especially in hot seasons and regions. When the brake discs and calipers are exposed to high temperatures for extended periods, continuous braking increases the risk of heat fade in the friction pairs, leading to a decrease in braking torque. Air-cooled brake discs rely on the rotation of the brake disc itself, which generates airflow through the air ducts for heat dissipation. However, because some equipment, such as winches, has shafts that mount the brake discs rotate at relatively low speeds, the energy generated by the airflow from the brake disc's rotation is very small, resulting in limited heat dissipation from air-cooled discs. Their cooling effect is primarily limited to increasing the heat dissipation area. Water-cooled brake discs require circulating water, specific site conditions, and special maintenance during winter or relocation to prevent freezing, cracking, or rusting, increasing maintenance procedures.

[0003] Therefore, it is necessary to develop a forced air-cooled disc brake control system to overcome the above-mentioned technical problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a forced air-cooled disc brake control system, which effectively overcomes the defects of the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A forced air-cooled disc brake control system includes a brake disc, an arc-shaped caliper holder, and brake calipers. The brake disc is coaxially mounted on a shaft component of an equipment carrier. The caliper holder is disposed on the upper part and one side periphery of the brake disc and is assembled and fixed to the equipment carrier. The brake calipers are mounted on the caliper holder, and the brake blocks of the brake calipers are distributed on both sides of the brake disc. The caliper holder has a flow channel, and the inner side of the caliper holder has a nozzle communicating with the flow channel. The flow channel is connected to an air supply control system. The brake disc is covered by a protective cover assembled with the equipment carrier. An airflow window is opened on the lower part of the outer surface of the protective cover, and a control component for opening or closing the airflow window is installed in the airflow window.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the aforementioned protective cover is equipped with an air inlet connector, which is connected to the aforementioned air supply control system and the flow channel respectively.

[0009] Furthermore, the aforementioned flow channels are provided in multiple ways and are distributed at intervals along the circumference of the aforementioned clamp, and each of the aforementioned flow channels is connected to the aforementioned air inlet connector via a pipeline.

[0010] Furthermore, the aforementioned control component is a louver.

[0011] Furthermore, the aforementioned flow channel extends through the inner and outer sides of the aforementioned clamp.

[0012] Furthermore, the inner port of the flow channel is provided with an internal thread, one end of the nozzle is provided with a threaded connection part, and is screwed into the inner port of the flow channel through the threaded connection part, and the outer surface of the other end of the nozzle is provided with an external hexagonal disassembly part.

[0013] Furthermore, the aforementioned air supply control system includes an air source and an air supply pipeline. The air source is connected to the aforementioned flow channel through the air supply pipeline. The air supply pipeline is provided with an air intake main valve, an air source triple unit, a one-way valve, a pressure reducing valve, and a hydraulically or electrically controlled directional valve in sequence from upstream to downstream.

[0014] Furthermore, it also includes a manual reversing valve, which is connected to the air supply pipeline via a pipeline and is connected in parallel with the hydraulic or electric reversing valve.

[0015] Furthermore, it also includes an accumulator. The aforementioned air supply pipeline has a four-way valve connected in series between the aforementioned check valve and pressure reducing valve. The remaining two ports of the four-way valve are respectively connected to the pressure gauge and the aforementioned accumulator.

[0016] Furthermore, an exhaust pipeline is connected to the pipe section between the aforementioned pressure reducing valve and the hydraulically or electrically controlled directional valve, and an exhaust unloading valve is installed on the aforementioned exhaust pipeline.

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] Example

[0028] like Figure 1 , 2As shown in Figures 3 and 4, the forced air-cooled disc brake control system of this embodiment includes a brake disc 1, an arc-shaped caliper 2, and a brake caliper 3. The brake disc 1 is coaxially mounted on a shaft component (represented by B in the figure) of the equipment carrier (represented by A in the figure). The caliper 2 is disposed on the upper part and one side periphery of the brake disc 1 and is assembled and fixed with the equipment carrier. The brake caliper 3 is mounted on the caliper 2, and the brake blocks of the brake caliper 3 are distributed on both sides of the brake disc 1. The caliper 2 is provided with a flow channel 21, and the inner side of the caliper 2 is provided with a nozzle 4 communicating with the flow channel 21. The flow channel 21 is connected to the air supply control system. The brake disc 1 is covered with a protective cover 5 assembled with the equipment carrier. An airflow window 51 is opened on the lower part of the outer surface of the protective cover 5, and a control component for opening or closing the airflow window 51 is installed in the airflow window 51.

[0029] In this embodiment, the forced air-cooled disc brake control system, taking a winch as an example, has a brake disc 1 mounted on both ends of the winch drum (a shaft-type component). A protective cover 5, which is assembled with the winch frame, is wrapped around the winch in the direction corresponding to the outer periphery of the brake disc 1. The clamp frame 2 is assembled and fixed with the winch frame and is distributed around the brake disc 1 (with a gap between them). A brake caliper 3 (a conventional product) is set on the clamp frame 2. The two sets of brake blocks of the brake caliper 3 are distributed on both sides of the brake disc 1. The brake is applied by clamping and contacting both sides of the brake disc 1, thereby braking the winch drum or releasing the brake. During braking, air is supplied to the flow channel 21 of the caliper 2 through the air supply control system, and then sprayed onto the brake disc 1 through the nozzle 4 to cool the brake disc 1. At the same time, the airflow flows inside the protective cover 5 and is finally discharged through the airflow window 51 at the lower part of the outer surface of the protective cover 5. The whole process forces the brake disc to be blown, which can perform routine cleaning of the brake caliper and brake disc. The airflow carries away the friction dust after braking and the heat generated during the braking process, enhancing the heat dissipation effect of the existing solid disc and air-cooled disc, and reducing the risk of heat fade of the friction pair.

[0030] In this embodiment, the protective cover 5 is provided with an air inlet connector, which is connected to the air supply control system and the flow channel 21 respectively. The air path is connected through the air inlet connector and pipeline, which facilitates pipeline layout.

[0031] In a preferred embodiment, multiple flow channels 21 are provided and are distributed at intervals along the circumference of the clamp 2, and each flow channel 21 is connected to the air inlet connector via a pipeline.

[0032] In the above implementation scheme, an air intake main pipe can be provided inside the protective cover 5. The air intake main pipe is connected to the air intake connector. The air intake main pipe is connected to multiple branch pipes. The multiple branch pipes are connected and communicated with multiple flow channels 21 in a one-to-one correspondence, so as to realize the gas diversion to each nozzle 4.

[0033] In this embodiment, the aforementioned control component is a louver. The louver is opened when needed and closed when not in use to prevent insects, rodents, or foreign objects from entering. When the louver is open, the slats are tilted downwards, and the airflow window 51 has a small opening to prevent rainwater from entering or small animals from slipping in.

[0034] In this embodiment, the flow channel 21 penetrates the inner and outer sides of the clamp 2.

[0035] As a preferred implementation method, such as Figure 5 As shown, the inner port of the flow channel 21 is provided with an internal thread, one end of the nozzle 4 is provided with a threaded connection part 41, and is screwed into the inner port of the flow channel 21 through the threaded connection part 41, and the outer surface of the other end of the nozzle 4 is provided with an external hexagonal disassembly part 42.

[0036] In the above embodiment, the external hexagonal disassembly part 42 facilitates the twisting of the nozzle 4 with tools, which is beneficial for the disassembly and assembly of the threaded connection part 41 of the nozzle 4 at the inner port of the flow channel 21.

[0037] As a preferred implementation method, such as Figure 6 As shown, the above-mentioned air supply control system includes an air source 61 and an air supply pipeline 62. The air source 61 is connected to the flow channel 21 through the air supply pipeline 62. The air supply pipeline 62 is provided with an air intake main valve 63, an air source triplet 64, a one-way valve 65, a pressure reducing valve 66, and a hydraulic or electric reversing valve 67 in sequence from upstream to downstream.

[0038] In the above implementation scheme, the air source 61 (which can be compressed air, specifically compressed gas output from an air compressor) sequentially passes through the main inlet valve 63, the air source triplet 64, the check valve 65, the pressure reducing valve 66, and the hydraulic or electric directional valve 67. The main inlet valve 63 effectively controls the flow rate and on / off status of the air supply pipeline 62. The air source triplet 64 filters, purifies, removes water, and reduces the pressure of the gas. The check valve 65 effectively prevents backflow of gas, ensuring that the gas always flows towards the nozzle 4. The pressure reducing valve 66 can reduce the pressure of the gas delivered from the air source 61, avoiding damage to the pipeline caused by high-pressure gas. The hydraulic or electric directional valve 67 is switched by the control signal of the control source (a in the figure) connected to it, thereby connecting or disconnecting the air path to the nozzle 4. This allows gas to be blown towards the brake disc 1 through the nozzle 4. Since there is a certain gap between the brake disc 1 and the caliper 2, the high-speed airflow ejected from the nozzle 4 flows through this gap and blows the hot air out through the airflow window 51 on the protective cover 5 for air circulation.

[0039] The air supply control system can be based on the original disc brake hydraulic control system and can be adapted to the original system, including adding an air path and an independent valve block to the original system, and adding an independent control valve block to the original control console.

[0040] In a preferred embodiment, a manual reversing valve 68 is also included, which is connected to the air supply duct 62 via a pipeline and is connected in parallel with the hydraulic or electric reversing valve 67.

[0041] In the above implementation scheme, the manual reversing valve 68 can be set to manually connect or disconnect the air circuit. Normally, the manual reversing valve 68 is in the off state. When needed (to clean the panel or test the air circuit), it can be manually operated, making the operation more flexible.

[0042] In a preferred embodiment, the system also includes an accumulator 69. The air supply duct 62 has a four-way valve connected in series between the check valve 65 and the pressure reducing valve 66. The remaining two ports of the four-way valve are connected to the pressure gauge 70 and the accumulator 69, respectively.

[0043] In the above implementation scheme, the accumulator 69 can store energy in the gas, stabilize the pressure in the system pipeline, or maintain a certain high pressure momentarily (shortly) during intermittent purging, resulting in better purging effect. Simultaneously, the pressure gauge 70 can monitor the pressure in the air supply pipeline 62 in real time. When the pressure is unstable, operators can flexibly operate the accumulator 69 to release gas and perform "pressure replenishment" based on the real-time data from the pressure gauge 70.

[0044] In this embodiment, the accumulator 69 can be a conventional gas storage cylinder with an exhaust valve at the cylinder opening.

[0045] In a preferred embodiment, an exhaust pipeline is connected to the pipe section between the pressure reducing valve 66 and the hydraulic or electric directional valve 67, and an exhaust unloading valve 71 is provided on the exhaust pipeline.

[0046] In the above implementation scheme, if it is necessary to relieve system pressure during system inspection or maintenance, the exhaust and unloading valve 71 is opened to relieve system pressure, making maintenance safer.
