Description

Technical Field

[0001] The invention relates to the technical field of railway vehicle braking, and in particular to a manual brake fastener. Background Art

[0002] The manual brake is an important braking device on railway vehicles. During the operation of railway vehicles, such as trains, under normal circumstances, they mainly rely on the train's automatic air brake and other systems to achieve braking and stopping operations. However, when the train needs to stop for a long time, especially on some sloped lines, the manual brake can be tightened to put the vehicle's wheels in a braking state to prevent the vehicle from slipping due to gravity and other reasons, and avoid possible safety accidents such as collisions.

[0003] Usually, the fastening tool for the manual brake is a manual brake fastener, which includes a hook, a nut, a screw, a hook and a handle. When in use, the hook is hung on the support plate on the train, and the hook is hung on the brake chain of the manual brake. The handle is used to turn the screw to make the hook tighten the brake chain, thereby achieving the braking and anti-skid effect. However, this manual brake fastener is purely manually operated and is laborious to use. Summary of the invention

[0004] In view of this, the present invention aims to provide a manual brake fastener to save manpower.

[0011] A screw rod is rotatably disposed in the outer cylinder and threadedly connected to the inner cylinder;

[0012] The electric drive assembly is detachably inserted into one end of the outer cylinder away from the hook, and can drive the screw to rotate to drive the inner cylinder to slide.

[0013] Furthermore, one end of the screw is rotatably connected to the outer cylinder and is provided with a first connecting disk, and a slot is provided on the first connecting disk;

[0014] The electric drive assembly includes a housing, a motor, a reducer, a battery and a second connecting plate;

[0015] The motor, reducer and battery are arranged in the housing, the motor is electrically connected to the battery, the reducer is connected to the output end of the motor, and the second connecting disk is rotatably connected to the housing and coaxially fixedly connected to the output end of the reducer;

[0016] The second connection disk is provided with an insert block. When the insert block is inserted into the slot, the second connection disk follows the first connection disk, so that the motor can drive the screw rod.

[0017] Furthermore, a tension sensor is provided between the outer cylinder and the hook, and a connecting line of the tension sensor is led out and a first contact point is provided in the outer cylinder;

[0018] A controller is disposed in the outer cylinder, the controller is electrically connected to the motor and the battery, a signal input port of the controller is connected and a second contact is disposed on the outer shell;

[0019] When the electric drive assembly is installed in the outer cylinder, the first contact contacts the second contact to form an electrical connection between the tension sensor and the controller; when the tension collected by the controller is greater than a set threshold, a stop command can be issued to the motor.

[0020] Furthermore, the manual brake fastener further comprises a limiting assembly, wherein the limiting assembly comprises a slider, a lever, a clamping block and a first elastic member;

[0021] The slider is slidably mounted on the second connection disk and can be received in the second connection disk due to the compression of the first connection disk; the lever is pivotally connected to the second connection disk, one end of which abuts against the slider and the other end of which is provided with a long hole; the block is slidably mounted on the second connection disk and has a connecting rod mounted in the long hole; the first elastic member is arranged in the second connection disk;

[0022] The housing is provided with a plurality of limiting teeth along the circumferential direction of the rotation axis of the second connecting disk, and when the clamping block is engaged with the limiting teeth, the second connecting disk cannot rotate;

[0023] When the lever pushes the clamping block into the second connection disk, the first elastic member stores energy, and when the first elastic member releases energy, the clamping block is pushed toward the housing to engage with the limiting tooth.

[0024] Furthermore, two of the shifting rods are provided and arranged in a scissor-like shape, and two of the clamping block and the first elastic member are also provided corresponding to the shifting rods respectively.

[0025] Furthermore, the plug block is telescopically arranged along the axial direction of the second connection disk, and a second elastic member is arranged between the plug block and the second connection disk;

[0026] When the inserting block is received in the second connecting plate, the second elastic member stores energy, and when the second elastic member releases energy, the inserting block extends out of the second connecting plate.

[0027] Furthermore, the inner cylinder is provided with a convex strip, and the outer cylinder is provided with a sliding groove for the convex strip to slide;

[0028] A wiring cavity connected to the outer cylinder along the sliding direction of the inner cylinder is provided in the convex strip, and the wiring cavity is used for arranging the connection line of the tension sensor.

[0029] Furthermore, the outer cylinder is provided with a rectangular insertion opening for inserting the electric drive assembly, and a limiting ring protruding inward is provided at the insertion opening, and a protective assembly is provided in the insertion opening;

[0030] The protection assembly includes hinge plates respectively hinged on four inner walls of the insertion port, and a third elastic member arranged between the hinge plates and the insertion port;

[0031] When the hinge plate is pushed by external force, it can rotate against the inner wall of the insertion port and make the third elastic member store energy. When the third elastic member releases energy, the hinge plate is pushed against the limit ring, and the four hinge plates together form a closure for the insertion port.

[0032] Further, the protection assembly includes a first hinge plate and three second hinge plates, the length of the first hinge plate is greater than the length of the second hinge plate, the second hinge plate is provided with an inclined second sealing surface, and the first hinge plate is provided with a first sealing surface that follows the second sealing surface;

[0033] When the three second hinge plates abut against the limiting ring, the first hinge plate can rotate to make the first sealing surface seal against the second sealing surface.

[0034] Furthermore, the inner cylinder has a threaded block threadedly connected to the screw rod, and a guide block rotatably connected to one end of the screw rod that penetrates the inner cylinder, and the guide block has a roller that rolls against the inner wall of the inner cylinder.

[0035] Compared with the prior art, the present invention has the following advantages:

[0036] The human-powered brake fastener described in the present invention, by providing a detachable electric drive component, can drive the screw to rotate by the electric drive component, so that the inner cylinder slides relative to the outer cylinder, thereby realizing the extension or contraction of the hook, and tightening or loosening the brake chain of the human-powered brake without manually twisting the screw, which not only saves manpower but also improves the tightening efficiency. When multiple human-powered brakes need to be tightened at the same time, only one electric drive component can be carried to tighten the screws of different human-powered brake fasteners respectively, which is more convenient to use.

[0037] Secondly, the battery supplies power to the motor, the motor reducer drives the second connection disk to rotate, and the plug block is inserted into the slot, so that the second connection disk can stably drive the first connection disk to rotate. A tension sensor is set between the hook and the outer cylinder, which can collect tension data to the controller, so that the controller can stop the motor after the hook tightens the brake chain to ensure the tension of the brake chain. The contact connection method can make the electric drive component more convenient to insert into the outer cylinder compared to the plug-in plug-in method.

[0038] In addition, the limiting component can limit the rotatable state of the second connecting disk, so that the second connecting disk can only rotate after it is tightly attached to the first connecting disk and the first contact is fully in contact with the second contact, so as to prevent the tension sensor from failing when the motor is working. There are two levers, and the two levers are arranged in a scissor-like shape, and the card block and the first elastic member are correspondingly set, so that the card block can react more sensitively and reliably when the slider moves. The plug block is set to a retractable form and cooperates with the second elastic member, so that even if the plug block is not inserted into the slot when the electric drive component is inserted into the outer cylinder, the electric drive component can be normally inserted into place. After the motor is started, during the rotation of the second connecting disk, the plug block can automatically pop out and be inserted into the slot when it is aligned with the slot.

[0039] Furthermore, the inner cylinder is provided with a convex strip and the outer cylinder is provided with a slide groove, which can guide the inner cylinder to the outer cylinder. At the same time, the wiring cavity is provided in the convex strip, which does not affect the normal use of the tension sensor connection when the inner cylinder moves. The protective component can protect the insertion port of the outer cylinder when the electric drive component is not inserted into the outer cylinder, and prevent external debris from entering the insertion port. At the same time, after the electric drive component is inserted into the insertion port, the hinge plate can play the function of clamping the electric drive component.

[0040] In addition, three second hinge plates and one first hinge plate are provided. When the electric drive assembly is moved out of the insertion port, the second connection plate will continue to block the first hinge plate, while the second hinge plate will be closed first without being blocked by the second connection plate. After the second connection plate is moved out of the outer cylinder, the first hinge plate can be closed and sealed on the three second hinge plates, which has a better sealing and protection effect. A guide block is provided on the screw rod, so that the movement of the inner cylinder is not easy to get stuck when the screw rod rotates. At the same time, a roller is provided to reduce the friction between the guide block and the inner cylinder, so that the guide block slides more smoothly in the inner cylinder.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0069] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0070] This embodiment relates to a manual brake fastener to save manpower.

[0071] In terms of overall structure, refer to Figure 1 and Figure 2 As shown, a manual brake fastener of the present embodiment includes an outer cylinder 1, an inner cylinder 2, a hook 3, a hook 4, a screw 5 and an electric drive assembly 6. The outer cylinder 1 is a rectangular tube with openings at both ends. The inner cylinder 2 is slidably inserted into the outer cylinder 1. The hook 3 is arranged at one end of the inner cylinder 2 that can slide out of the outer cylinder 1, and is used to hook the brake chain. The hook 4 is hinged on the outer cylinder 1, and is used to hook on the support plate of the train. The screw 5 is rotatably arranged in the outer cylinder 1 and is threadedly connected to the inner cylinder 2. The electric drive assembly 6 is detachably inserted in one end of the outer cylinder 1 away from the hook 3, and can drive the screw 5 to rotate to drive the inner cylinder 2 to slide.

[0072] As configured above, the manual brake fastener of this embodiment, by providing a detachable electric drive component 6, can drive the screw 5 to rotate by the electric drive component 6, so that the inner cylinder 2 slides relative to the outer cylinder 1, thereby realizing the extension or contraction of the hook 3, and tightening or loosening the brake chain of the manual brake without manually screwing the screw 5, which not only saves manpower but also improves the tightening efficiency. When multiple manual brakes need to be tightened at the same time, only one electric drive component 6 can be carried to tighten the screws 5 of different manual brake fasteners respectively, which is more convenient to use.

[0073] Among them, refer to Figure 2 and Figure 3As shown, one end of the screw 5 is rotatably connected to the outer cylinder 1 and is provided with a first connection disk 501, and a slot 5011 is provided on the first connection disk 501. The electric drive assembly 6 includes a housing 601, a motor 602, a reducer 603, a battery 604 and a second connection disk 605. The motor 602, the reducer 603 and the battery 604 are arranged in the housing 601, the motor 602 is electrically connected to the battery 604, the reducer 603 is connected to the output end of the motor 602, and the second connection disk 605 is rotatably connected to the housing 601 and is coaxially fixedly connected to the output end of the reducer 603. The second connection disk 605 is provided with an insert block 606. When the insert block 606 is inserted into the slot 5011, the second connection disk 605 follows the first connection disk 501, so that the motor 602 can drive the screw 5. The battery 604 supplies power to the motor 602 , and the motor 602 drives the second connection disk 605 to rotate through the reducer 603 . The plug block 606 is inserted into the slot 5011 , and the second connection disk 605 can stably drive the first connection disk 501 to rotate.

[0074] Specifically, the plug-in block 606 of this embodiment is in a fan-shaped ring shape and is coaxial with the second connection plate 605. The edge of the slot 5011 is provided with a chamfer to facilitate the insertion of the plug-in block 606.

[0075] Secondly, in order to make the tension of the manual brake fastener on the brake chain a standard tension, a tension sensor 7 is provided between the outer cylinder 1 and the hook 4, and the connection line of the tension sensor 7 is led out and a first contact 701 is provided in the outer cylinder 1. A controller 607 is provided in the outer cylinder 1, and the controller 607 is electrically connected to the motor 602 and the battery 604. The signal input port of the controller 607 is connected and a second contact 6071 is provided on the housing 601. When the electric drive assembly 6 is installed in the outer cylinder 1, the first contact 701 contacts the second contact 6071 to form an electrical connection between the tension sensor 7 and the controller 607. When the tension collected by the controller 607 is greater than the set threshold, a shutdown command can be issued to the motor 602.

[0076] Usually, there is an optimal range value for the tension of the brake chain, and the threshold value can be determined based on the range value. By setting a tension sensor 7 between the hook 4 and the outer cylinder 1, the tension data can be collected and given to the controller 607, so that the controller 607 can stop the motor 602 after the hook 4 tightens the brake chain to ensure the tension of the brake chain. The contact connection method can make the electric drive component 6 more convenient to insert into the outer cylinder 1 compared to the plug-in connection method.

[0077] Specifically, in this embodiment, the motor 602 is a servo motor 602, the reducer 603 is a planetary reducer 603, and the battery 604 is a lithium battery 604, which can stably drive the screw 5 to rotate. An operating switch 609 is also provided at the bottom of the housing 601 to control the start and stop of the electric drive assembly 6.

[0078] In addition, refer to Figure 4 and Figure 5 As shown, the manual brake fastener further includes a limiting assembly 8, which includes a slider 801, a lever 802, a block 803 and a first elastic member 804. The slider 801 is slidably inserted into the second connection disk 605, and can be received into the second connection disk 605 due to the extrusion of the first connection disk 501. The lever 802 is pivotally connected to the second connection disk 605, one end of which abuts against the slider 801, and the other end is provided with a long hole 8021. The block 803 is slidably inserted into the second connection disk 605, and has a connecting rod 8031 ​​inserted into the long hole 8021. The first elastic member 804 is arranged in the second connection disk 605.

[0079] At the same time, a plurality of limiting teeth 6011 are provided on the housing 601 along the circumference of the rotation axis of the second connection disk 605. When the clamping block 803 is engaged with the limiting teeth 6011, the second connection disk 605 cannot rotate. When the lever 802 pushes the clamping block 803 into the second connection disk 605, the first elastic member 804 stores energy, and when the first elastic member 804 releases energy, the clamping block 803 is pushed toward the housing 601 to engage with the limiting teeth 6011.

[0080] In this way, the limiting component 8 is integrated on the second connecting disk 605, and can limit the rotatable state of the second connecting disk 605, so that the second connecting disk 605 can only rotate after it is close to the first connecting disk 501 and the first contact 701 is fully in contact with the second contact 6071, so as to prevent the tension sensor 7 from failing when the motor 602 is working, resulting in the hook 3 over-tightening the brake chain. In this embodiment, the first contact 701 slightly protrudes from the outer cylinder 1, and the second contact 6071 slightly protrudes from the outer shell 601, so that the first contact 701 can contact the second contact 6071.

[0081] Furthermore, in order to improve the stability in use, two levers 802 are provided, arranged in a scissor-like manner, and two clamping blocks 803 and first elastic members 804 are also provided corresponding to the levers 802. Providing two levers 802, arranging the two levers 802 in a scissor-like manner, and correspondingly providing the clamping blocks 803 and the first elastic members 804 can make the reaction of the clamping blocks 803 more sensitive and reliable when the slider 801 moves.

[0082] Furthermore, in order to make the electric drive assembly 6 easier to insert, the insert block 606 is retractably arranged along the axial direction of the second connection disk 605, and a second elastic member 608 is arranged between the insert block 606 and the second connection disk 605. When the insert block 606 is received in the second connection disk 605, the second elastic member 608 stores energy, and when the second elastic member 608 releases energy, the insert block 606 extends out of the second connection disk 605. The insert block 606 is arranged in a retractable form and cooperates with the second elastic member 608. Even if the insert block 606 is not inserted into the slot 5011 when the electric drive assembly 6 is inserted into the outer cylinder 1, the electric drive assembly 6 can be inserted into place normally. After the motor 602 is started, during the rotation of the second connection disk 605, the insert block 606 can automatically pop out and be inserted into the slot 5011 when it is aligned with the slot 5011.

[0083] In addition, refer to Figure 2 As shown, a convex strip 201 is provided on the inner cylinder 2, and a slide groove 101 is provided in the outer cylinder 1 for the convex strip 201 to slide. A wiring cavity 202 is provided in the convex strip 201 and is connected to the outer cylinder 1 along the sliding direction of the inner cylinder 2. The wiring cavity 202 is used to arrange the connection line of the tension sensor 7. The convex strip 201 is provided on the inner cylinder 2, and the slide groove 101 is provided on the outer cylinder 1, which can play a guiding role of the outer cylinder 1 to the inner cylinder 2. At the same time, the wiring cavity 202 is provided in the convex strip 201, and the normal use of the connection line of the tension sensor 7 when the inner cylinder 2 moves is not affected.

[0084] For the purpose of protecting the inner parts of the outer cylinder 1, the outer cylinder 1 is provided with a rectangular insertion port 102 for inserting the electric drive assembly 6, and a limit ring 103 protruding inward is provided at the insertion port 102, and a protective component 9 is provided in the insertion port 102. The protective component 9 includes hinged plates respectively hinged on the four inner walls of the insertion port 102, and a third elastic member 903 arranged between the hinged plate and the insertion port 102. When the hinged plate is pushed by an external force, it can rotate against the inner wall of the insertion port 102, and the third elastic member 903 can store energy. When the third elastic member 903 releases energy, the hinged plate is pushed against the limit ring 103, and the four hinged plates together form a closure for the insertion port 102. The protection component 9 can protect the insertion port 102 of the outer cylinder 1 when the electric drive component 6 is not inserted into the outer cylinder 1, and prevent external debris from entering the insertion port 102. At the same time, after the electric drive component 6 is inserted into the insertion port 102, the hinged plate can clamp the electric drive component 6.

[0085] Among them, refer to Figure 2 , Figure 6 and Figure 7As shown, the protection assembly 9 includes a first hinge plate 901 and three second hinge plates 902. The length of the first hinge plate 901 is greater than that of the second hinge plate 902. The second hinge plate 902 is provided with an inclined second sealing surface 9021. The first hinge plate 901 is provided with a first sealing surface 9011 that follows the second sealing surface 9021. When the three second hinge plates 902 abut against the limiting ring 103, the first hinge plate 901 can rotate so that the first sealing surface 9011 seals against the second sealing surface 9021. Three second hinged plates 902 and one first hinged plate 901 are provided. When the electric drive assembly 6 is moved out of the insertion port 102, the second connecting disk 605 will continue to block the first hinged plate 901, while the second hinged plate 902 will be closed first without being blocked by the second connecting disk 605. After the second connecting disk 605 is moved out of the outer cylinder 1, the first hinged plate 901 can be closed and sealed on the three second hinged plates 902, thereby achieving a better sealing and protective effect.

[0086] In order to make the inner cylinder 2 slide more smoothly, refer to Figure 2 As shown, the inner cylinder 2 of this embodiment has a threaded block 203 threadedly connected to the screw rod 5, and a guide block 204 rotatably connected to one end of the screw rod 5 that penetrates the inner cylinder 2, and the guide block 204 has a roller 205, and the roller 205 rolls against the inner wall of the inner cylinder 2. The guide block 204 is arranged on the screw rod 5, so that the movement of the inner cylinder 2 is not easy to get stuck when the screw rod 5 rotates, and the roller 205 is arranged to reduce the friction between the guide block 204 and the inner cylinder 2, so that the guide block 204 slides more smoothly in the inner cylinder 2. The guide block 204 is a rectangular block, and two rollers 205 are arranged on each of the four side walls facing the inner wall of the inner cylinder 2.

[0087] The method of using the manual brake fastener of this embodiment is as follows: hang the hook 4 on the support plate of the train, hang the hook 3 on the brake chain of the manual brake, align the electric drive assembly 6 with the first contact 701 and insert it into the outer cylinder 1, start the operating switch 609, the motor 602 rotates, and the inner cylinder 2 contracts until the tension reaches a preset threshold value, then the motor 602 stops, the manual brake is fastened, and the electric drive assembly 6 can be pulled out.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
