It should be noted that an auxiliary driver can be arranged at the position of the hydraulic telescopic cylinder 501, when the hydraulic telescopic cylinder 501 is abnormal, the auxiliary driver starts the movable end of the hydraulic telescopic cylinder 501 to extend, and the auxiliary driver is an insurance starting device, which is the prior art and will not be described in detail.

[0021] The middle part of the inner wall of the brake support 3 is hingedly connected with a driving lever 503, the top of the driving lever 503 is hingedly connected with the lower part of the driving connecting rod 502, the lower part of the driving lever 503 is hingedly connected with the side wall of the corresponding brake clamp plate 4, and the brake clamp plate 4 is slidingly arranged at the side wall position of the brake support 3.

It should be noted that through the cooperation of the guide groove and the guide rod, the two brake clamp plates 4 at the lower part of the brake support 3 can be clamped on the side wall of the track in a translational manner. For the existing disclosed patent CN118082909A, the deflection clamping mode is easy to cause the clamping contact surface to be too small, and the clamping mode adopted by the present technical solution is more stable.

[0025] In this embodiment, as shown in Figures 1 to 10As shown, the parking locking mechanism 6 comprises a movable slot 601, the inside of the movable slot 601 is slidably provided with a parking clamping plate 602, the middle of the parking clamping plate 602 is movably inserted with a movable rod 603, and the movable rod 603 is rotationally arranged at the bottom of the movable slot 601, and the top of the movable rod 603 is eccentrically installed with a driven shaft 604. It should be noted that when the driven shaft 604 eccentrically rotates with the movable rod 603, the movable rod 603 moves with the parking clamping plate 602 to the outside of the movable slot 601, so that the parking clamping plate 602 is attached to the side wall of the track to brake; the distance from the side wall of the movable slot 601 to the parking clamping plate 602 is the same as the distance of the eccentric movement of the driven shaft 604 with the movable rod 603, so as to avoid interference.

[0026] The upper part of the inner wall of the brake clamping plate 4 is provided with a transmission slot 605, the transmission slot 605 and the movable slot 601 are rotationally connected with a driving shaft 606, the lower part of the driving shaft 606 is fixedly connected with a main chuck 607, the upper part of the driven shaft 604 is slidably provided with a from chuck 608 matched with the main chuck 607, and the bottom of the from chuck 608 and the surface of the driven shaft 604 are fixedly connected with an extrusion spring 609. It should be noted that the main chuck 607 and the from chuck 608 are provided as matched gear discs, when the movable rod 603 is attached with the parking clamping plate 602 to the side wall of the track, the driven shaft 604 and the movable rod 603 cannot continue to move with the parking clamping plate 602, at this time the main chuck 607 pushes the from chuck 608 to move downward in the sliding slot during rotation, and then the extrusion spring 609 is compressed, so that the main chuck 607 no longer rotates with the from chuck 608 and the driven shaft 604, and the transmission state is separated.

[0027] The top of the driving shaft 606 is installed with a circular gear 610, the inside of the transmission slot 605 is slidably provided with a transmission rack 611 matched with the circular gear 610, and one end of the transmission rack 611 penetrates through the brake clamping plate 4 and is fixedly connected to the surface of the brake support 3. It should be noted that when the brake clamping plate 4 moves to the track direction at the lower part of the brake support 3, the transmission rack 611 is engaged with the circular gear 610, so that the driving shaft 606 drives the from chuck 608 and the driven shaft 604 to rotate synchronously through the main chuck 607, at this time the driven shaft 604 eccentrically rotates with the movable rod 603, and the movable rod 603 is attached with the surface of the parking clamping plate 602 to the side wall of the track to brake; and the parking clamping plate 602 is attached to the side wall of the track to generate frictional resistance, when the frictional resistance between the parking clamping plate 602 and the side wall of the track is greater during the slope parking process, the greater the frictional resistance will drive the parking clamping plate 602 to generate a greater tendency of deviation, when the parking clamping plate 602 deviates, the greater the angle of the parking clamping plate 602 deviates under the action of the eccentrically rotating movable rod 603, the tighter the parking clamping plate 602 is attached to the side wall of the track, and the risk of creep during the slope parking process is effectively avoided.

[0028] In this embodiment, as shown in Figures 1 to 10 The bottom of the transmission groove 605 and the top of the movable groove 601 are provided with a circular hole, and the driving shaft 606 and the driven shaft 604 are both movably installed in the inside of the circular hole through a connecting bearing.

[0029] The upper part of the driven shaft 604 is symmetrically provided with a sliding groove, and the inner ring of the chuck 608 is symmetrically fixedly connected with a sliding block, and the two sliding blocks are respectively slidably arranged in the inside of the two sliding grooves. The lower part of the driven shaft 604 is fixedly sleeved with a spacer ring, and the compression spring 609 is arranged between the top of the spacer ring and the bottom of the chuck 608. It should be noted that: the structure of the transmission disengagement when the main chuck 607 and the chuck 608 are overloaded can be provided, and when the track is not worn, the movable rod 603 can only eccentrically rotate ninety degrees with the parking clamping plate 602 and be attached to the track during the movement of the brake clamp plate 4 to the track direction, and the brake clamp plate 4 that continues to move will not drive the parking clamping plate 602 to be deflected; when the track surface is worn, the parking clamping plate 602 at the non-worn position is attached to the track and stops from being offset, and because the brake clamp plate 4 continues to move, the circular gear 610 and the transmission rack 611 continue to engage, so that the driving shaft 606 at the track wear position continues to eccentrically rotate with the main chuck 607, the chuck 608, the driven shaft 604 and the movable rod 603, at this time, the parking clamping plate 602 corresponding to the movable rod 603 continues to be offset and is attached to the track side wall, so that when the track is worn, the parking clamping plate 602 at different positions of the brake clamp plate 4 can be attached to the track side wall to brake, avoiding the uneven contact pressure caused by the wear of the track side wall, and improving the stability of the parking brake.

[0030] In this embodiment, as shown in Figures 1 to 10 The inner bottom surface of the movable groove 601 is provided with a reset groove, and the lower part of the movable rod 603 is rotatably connected in the inside of the reset groove. A reset torsion spring is fixedly connected between the inner wall of the reset groove and the surface of the movable rod 603. It should be noted that: the reset groove is set to be 1.5 times the eccentric rotation diameter of the movable rod 603 to avoid interference, and the reset torsion spring moves the movable rod 603 back to its original position after the parking clamping plate 602 is separated from the track.

[0031] In this embodiment, as shown in Figures 1 to 10 The end of the transmission rack 611 away from the circular gear 610 is fixedly connected with a connecting rod, and the top of the transmission groove 605 is provided with a horizontal groove matched with the connecting rod. The connecting rod is fixedly connected with the surface of the brake support 3 by penetrating the horizontal groove.

[0032] The inner ring of the circular gear 610 is fixedly connected with the upper part of the driving shaft 606. It should be noted that through the one-way bearing, when the brake clamp plate 4 resets during movement, the circular gear 610 and the transmission rack 611 reset during meshing transmission, the circular gear 610 will not rotate with the driving shaft 606, and when the brake clamp plate 4 resets to the limit state, the transmission rack 611 and the circular gear 610 are disengaged, at this time the reset torsion spring starts to reset the movable rod 603 and the parking clamp plate 602.

[0033] In this embodiment, as shown in Figures 1 to 10 A method for using a brake device of a downhole steel wire rope traction toothed rail card rail vehicle, comprising the following steps: S1, during use, when parking brake is needed, the movable end of the hydraulic telescopic cylinder 501 is started to move downward, the movable end of the hydraulic telescopic cylinder 501 is deflected with the hinged driving connecting rod 502, the two driving connecting rods 502 push the two driving levers 503 to swing in opposite directions, the lower part of the driving lever 503 pulls the hinged brake clamp plate 4 to slide in the guide groove position on the surface of the brake support 3, and the brake clamp plate 4 is driven to move to the side wall of the track to perform brake operation.

[0034] S2, when the brake clamp plate 4 slides in the brake support 3, the transmission rack 611 is fixedly connected with the surface of the brake support 3 and will not move synchronously with the brake clamp plate 4, the circular gear 610 in the brake clamp plate 4 is meshed with the transmission rack 611, the driving shaft 606 and the main chuck 607 are synchronously rotated by the circular gear 610, the main chuck 607 is synchronously rotated with the driven shaft 604 during cooperation and clamping, the driven shaft 604 is rotated with the eccentrically connected movable rod 603, the movable rod 603 is eccentrically moved with the movable sleeve connected parking clamp plate 602 in the active groove 601, at this time the brake clamp plate 4 is tightly attached to the surface of the track with the side wall of the parking clamp plate 602, and the brake effect is improved.

[0035] S3, and after the parking clamping plate 602 is attached to the rail side wall, the slave chuck 608 on the driven shaft 604 cannot continue to rotate with the master chuck 607 on the driving shaft 606, at which time the inclined surface at the lower part of the master chuck 607 extrudes the slave chuck 608 to slide downward on the surface of the driven shaft 604 and disengage the transmission state, so that the rotating master chuck 607 cannot rotate with the slave chuck 608, and when the rail side wall is worn, under the action of the disengaged transmission of the master chuck 607 and the slave chuck 608, the parking clamping plate 602 that is not attached to the rail no longer continues to deviate with the movement of the brake clamp plate 4, and the parking clamping plate 602 at the worn position is not attached to the rail, at which time the transmission rack 611 and the circular gear 610 are engaged to transmit, so that the parking clamping plate 602 continues to deviate with the movement of the brake clamp plate 4, until the parking clamping plate 602 is completely attached to the rail side wall, so that when the rail side wall is worn, the parking clamping plate 602 at different positions on the brake clamp plate 4 can be stably attached to the rail side wall, the uniformity of the contact pressure during braking is improved, and the parking stability is improved.

[0036] S4, when the vehicle frame 1 is parked on the inclined rail surface, the vehicle frame 1 and the rail generate a rolling condition, at which time the parking clamping plate 602 on the brake clamp plate 4 generates a friction force with the rail, under the action of the friction force, the parking clamping plate 602 again brings the movable rod 603 to eccentrically deflect inside the movable groove 601, under the action of the eccentric rotation, the parking clamping plate 602 is more closely attached to the rail side wall, under the action of the parking clamping plate 602 that is eccentrically moved, the greater the friction force generated between the parking clamping plate 602 and the rail during the inclined parking process, the greater the distance of the eccentric movement of the parking clamping plate 602 to the rail side wall, so that the parking clamping plate 602 is more closely attached to the rail, thereby effectively ensuring the stability of the inclined parking and avoiding the risk of creeping.

A method for using a braking device for an underground wire rope traction rack rail vehicle, characterized in that: The method of using the underground wire rope traction rack rail clamping vehicle braking device according to any one of claims 1 to 8 comprises the following steps: S1, when the parking brake is applied, the hydraulic telescopic cylinder (501) drives the driving connecting rod (502) and the driving lever (503) to move, so that the brake clamp (4) slides along the guide groove of the brake bracket (3) and moves toward the side wall of the track to achieve braking; S2, when the brake clamp (4) slides, the transmission rack (611) is fixed, and its internal circular gear (610) engages with it, driving the driving shaft (606), the main chuck (607) and the driven shaft (604) to rotate, so that the movable rod (603) moves eccentrically with the parking clamping plate (602) in the movable groove (601), allowing the parking clamping plate (602) to fit closely to the track surface, thereby enhancing the braking effect; S3. After the parking clamping plate (602) is attached to the track, the slave chuck (608) cannot rotate with the main chuck (607), and the main chuck (607) squeezes the slave chuck (608) to disengage the transmission. When the side wall of the track is worn, the parking clamping plate (602) at the unattached part will continue to deviate until all parts are attached, ensuring uniform contact pressure and improving parking stability. S4. When the vehicle frame (1) slides on the inclined track, the friction between the parking clamping plate (602) and the track causes the movable rod (603) to deflect eccentrically again, so that the parking clamping plate (602) fits the track more closely. The greater the friction, the tighter the fit, effectively ensuring the stability of the slope parking and avoiding creep.
