Description

Technical Field

[0001] This utility model relates to the field of cable control technology, specifically to an integrated cable control box with two input ports and two output ports. Background Technology

[0002] Modern rail transit vehicles mostly employ air braking systems and are equipped with parking brake units, whose main function is to apply braking when the vehicle is stationary to prevent it from moving. There are generally two ways to release the parking brake: one is by using a network-controlled solenoid valve to inject air at a pressure generally greater than 500 kPa into the release chamber of the parking cylinder; in this process, the air pressure and control system play a crucial role. The second method is through a mechanical release device in the parking unit, commonly a parking release cable fixed to the bogie.

[0003] However, when the air supply system malfunctions, the parking brake will automatically apply, rendering the vehicle immobile. If the vehicle is on the line and needs rescue, the release cable is installed under the vehicle, and according to line safety requirements, personnel are prohibited from getting out of the vehicle to operate it. Therefore, the parking brake cannot be released, and the vehicle being rescued is towed away while the parking brake is applied, which can easily lead to a wheel-grip accident.

[0004] Existing technologies, on the one hand, lack ease of operation. The cable control structure of many rail vehicle auxiliary braking systems can only be operated from one side, requiring operators to run to the corresponding side of the vehicle to operate it, which affects the efficiency of releasing the rail vehicle and makes it impossible to quickly release the parking brake.

[0005] On the other hand, in terms of force transmission and conversion, the traditional cable system structure design is not reasonable enough, the force transmission efficiency is low, and it is impossible to achieve precise force transmission and distribution. As a result, components such as brake calipers cannot respond to the operator's operating instructions in a timely and accurate manner, affecting the timeliness and accuracy of braking. Utility Model Content

[0006] The purpose of this invention is to solve the problems of convenience and speed in single-sided cable operation, and to provide an integrated cable control box with two input ports and two output ports to overcome the shortcomings of the prior art, as detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This utility model provides an integrated cable control box with two input ports and two output ports, including two parking release control cables and two parking release execution cables, and a pulley transmission mechanism for realizing the linkage between the parking release control cables and the parking release execution cables is provided.

[0009] When one of the parking release control cables is operated, the pulley transmission mechanism can transmit force and displacement to the other two parking release actuator cables;

[0010] Both parking and easing control cables are equipped with hand easing cable structures distributed on both sides of the outside of the carriage.

[0011] Preferably, the pulley transmission mechanism includes two sets of first pulley assemblies and two sets of second pulley assemblies. The two sets of first pulley assemblies are respectively connected to two parking release control cables, and the two sets of second pulley assemblies are respectively connected to two parking release execution cables. A continuous S-shaped hanging rope is wound between the first pulley assemblies and the second pulley assemblies, and the two ends of the hanging rope are fixedly connected to the pulley box body through a fixing seat.

[0012] Preferably, the first pulley assembly includes a U-shaped fork, in which a first pulley is rotatably disposed, and one end of an input shaft is connected to the U-shaped fork, the other end of which is connected to a corresponding parking release control cable.

[0013] Preferably, the second pulley assembly includes a rectangular wheel frame, in which a second pulley is rotatably disposed. One end of an output shaft is connected to one side of the wheel frame, and the other end of the output shaft is connected to a corresponding parking release actuator cable. One end of a guide rod is connected to the other side of the wheel frame, and the other end of the guide rod is slidably connected to a guide hole on a fixed base. A compression spring is nested on the outside of the guide rod located between the fixed base and the wheel frame.

[0014] Preferably, both the first pulley and the second pulley have annular grooves along their circumference on their outer sides for winding the wire rope.

[0015] Preferably, the hand-relaxation cable structure includes a hand-relaxation support fixedly mounted on the vehicle body, and the hand-relaxation support is provided with a relief handle for pulling the parking relief control cable.

[0016] Preferably, the hand rest is detachably provided with a safety pin for securing the relief handle, and one end of the safety pin is provided with an end block.

[0017] Preferably, the end block is provided with a locking spring for preventing the safety pin from falling off, and the outer contour of the locking spring is arc-shaped.

[0018] Preferably, the hand rest support and the end block are connected to each other by a steel wire rope.

[0019] The beneficial effects are:

[0020] 1. By setting up hand-operated release cable structures on both sides of the car, the parking release control cable can be operated independently from either side of the rail vehicle. Combined with the "two-to-two" linkage design of the pulley transmission mechanism, pulling one cable can control two parking release execution cables, significantly improving operating efficiency.

[0021] 2. The multiple protection mechanisms consisting of safety pins, locking springs, and steel wire ropes in the hand-operated slow-release cable structure can effectively prevent accidental operation of the handle and dislodgement of the safety pins, ensuring stable braking. The design of the guide rod and compression spring in the pulley transmission mechanism ensures the smoothness of the force transmission process and the reliability of the reset, reducing the risk of brake failure.

[0022] 3. The pulley transmission mechanism achieves efficient force transmission and distribution through the cooperation of two sets of pulley assemblies and continuous S-shaped hanging ropes. It accurately transmits the force applied by the operator to the parking release control cable to the parking release execution cable, thereby controlling the brake caliper and improving the accuracy and consistency of braking response.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figures 1-4 As shown, this utility model provides an integrated cable control box with two input ports and two output ports, including two parking and easing control cables 2 and two parking and easing execution cables 3. A pulley transmission mechanism 5 is provided between the parking and easing control cables 2 and the parking and easing execution cables 3 to realize the linkage between the two. When one of the parking and easing control cables 2 is operated, the pulley transmission mechanism 5 can realize the transmission of force and displacement to the other two parking and easing execution cables 3. Each of the two parking and easing control cables 2 is provided with a hand easing cable structure 4 distributed on both sides of the outside of the carriage.

[0031] In practical applications, through the coordinated operation of components such as the parking and easing control cable 2, the pulley transmission mechanism 5, the parking and easing execution cable 3, and the hand easing cable structure 4, operators can operate the parking and easing control cable 2 from both sides outside the vehicle body via the hand easing cable structure 4. The force is then transmitted to the parking and easing execution cable 3 via the pulley transmission mechanism 5, thereby controlling the relevant braking components to achieve the purpose of parking or easing the vehicle's braking, ensuring the effective operation and safe control of the vehicle's braking system.

[0032] See instruction manual attached Figure 3 and Figure 4As shown, the pulley transmission mechanism 5 includes two sets of first pulley assemblies and two sets of second pulley assemblies. The two sets of first pulley assemblies are respectively connected to two parking release control cables 2, and the two sets of second pulley assemblies are respectively connected to two parking release actuation cables 3. A continuous S-shaped hanging rope 509 is wound between the first and second pulley assemblies, and both ends of the hanging rope 509 are fixedly connected to the pulley housing 1 via fixing seats 102. In practical applications, the force generated by the pulling of the parking release control cables 2 on the first pulley assembly is transmitted to the second pulley assembly through the winding of the hanging rope 509, realizing the transfer of force from the parking release control cables 2 to the parking release actuation cables 3. Through the coordinated work of the two sets of first pulley assemblies, the two sets of second pulley assemblies, the hanging rope 509, the fixing seats 102, and the pulley housing 1, the pulley transmission mechanism 5 realizes the transmission and conversion of force between the parking release control cables 2 and the parking release actuation cables 3. When the operator pulls the parking release control cable 2, the first pulley assembly moves the second pulley assembly via rope 509, completing the force transmission process for braking control. Its ingenious structural design ensures that operating one parking release control cable 2 simultaneously transmits force to both parking release execution cables 3, guaranteeing synchronized operation of the braking components on both sides of the vehicle and improving the consistency and reliability of the braking system control.

[0033] This embodiment proposes a specific first pulley assembly, which includes a U-shaped fork 502 for supporting and fixing the first pulley 501. The first pulley 501 can rotate flexibly in the U-shaped groove. One end of the input shaft 503 is connected to the U-shaped fork 502, and the other end of the input shaft 503 is connected to the corresponding parking relief control cable 2.

[0034] This embodiment proposes a specific second pulley assembly, which includes a wheel frame 505 for supporting and fixing the second pulley 504. The wheel frame 505 is rectangular in shape, and the second pulley 504 can rotate flexibly within the wheel frame 505. One end of an output shaft 506 is connected to one side of the wheel frame 505, and the other end of the output shaft 506 is connected to the corresponding parking release actuator cable 3. One end of a guide rod 507 is connected to the other side of the wheel frame 505, and the other end of the guide rod 507 is slidably connected to a guide hole on the fixed base 102. In practical applications, the guide rod 507 plays a guiding and limiting role, ensuring the stability of the movement of the wheel frame 505. A compression spring 508 is nested on the outside of the guide rod 507 located between the fixed base 102 and the wheel frame 505. Both the first pulley 501 and the second pulley 504 have annular grooves along their circumference for winding the steel wire rope 406.

[0035] The hand retardation cable structure 4 includes a hand retardation support 401 fixedly mounted on the vehicle body, which determines the installation position of the entire hand retardation cable structure 4 on the vehicle body, ensuring the accurate relative position of the hand retardation cable structure 4 with other components in the vehicle braking system, such as the parking release control cable 2, so that the components can work together. The hand retardation support 401 is equipped with a release handle 402 for pulling the parking release control cable 2. A safety pin 404 is detachably mounted on the hand retardation support 401 to secure the release handle 402, preventing accidental movement of the release handle 402 due to external forces or vibrations, ensuring the braking system remains stable in its current state, and avoiding safety hazards such as brake failure or accidental braking. One end of the safety pin 404 is equipped with an end block 403. A locking spring 405 is mounted on the end block 403 to prevent the safety pin 404 from falling off; the locking spring 405 has an arc-shaped outline. A steel wire rope 406 connects the hand retardation support 401 and the end block 403. The wire rope 406 can prevent the safety pin 404 from being accidentally lost after disassembly; on the other hand, it enhances the connection stability between the end block 403 and the hand rest support 401 to a certain extent, and at the same time, it plays a certain guiding and restraining role in the movement of the safety pin during the insertion and removal process.

[0036] In practical applications, operators can easily pull the parking release control cable 2 using the release handle 402 to manually control the vehicle's braking system. The locking mechanism, consisting of the safety pin 404, end block 403, and locking spring 405, ensures the handle is stably fixed after operation, guaranteeing the braking system is in the required working state. The wire rope 406 provides protection and auxiliary fixation for the safety pin, preventing it from being lost or accidentally detached. Overall, the manual release cable structure 4 achieves both convenience and safety for manual operation of the vehicle's braking system.

[0037] Working principle:

[0038] The parking release control cable 2 is pulled by operating the release handle 402 in the hand release cable structure 4 on the two parking release control cables 2. Specifically, the two hand release cable structures 4 are respectively set on the left and right sides of the vehicle body, so that the cable can be pulled from either side. The two parking release actuator cables 3 are respectively connected to the brake calipers of the two vehicle bodies. When operating the hand release cable structure 4 on either side, the brake calipers of the two vehicle bodies can be operated simultaneously. The safety pin 404 can lock the handle to prevent accidental operation, the locking spring 405 prevents the safety pin 404 from falling off, and the wire rope 406 serves as a suspension function after the safety pin 404 is pulled out.

[0039] In operation, the parking release control cable 2 is pulled, causing the first pulley 501 in the first pulley assembly connected to it to move within the pulley housing 1. Since a continuous S-shaped hanging rope 509 is wound between the first and second pulley assemblies, the movement of the first pulley 501 drives the second pulley 504 to move via the hanging rope 509, which in turn drives the wheel frame 505 to move. The output shaft 506 connected to the wheel frame 505 moves accordingly, thus transmitting force and displacement to the parking release execution cable 3. During this process, the guide rod 507 slides within the guide hole of the fixed base 102, and the compression spring 508 resets the parking release execution cable 3 after the release cable 2 is relaxed.

[0040] The parking and releasing actuator cable 3 is subjected to force transmission, which enables control of components such as the brake caliper, and completes braking-related operations such as parking and releasing.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
