Description

Technical Field

[0001] The utility model relates to the technical field of track safety equipment, in particular to a starting line clamp type parking device. Background Art

[0002] The existing Chinese utility model patent with publication number CN219382486U and name "Clip-type lifting anti-slip actuator for the hairline clamp" controls the opening and closing degree of the brake caliper through the plunger cylinder, thereby realizing the conversion of the braking position and the relief position. However, each brake caliper needs to be equipped with multiple sets of plunger cylinder drives. The more plunger cylinders there are, the greater the power of the hydraulic station required, which will not only increase the production cost, but also increase the operating cost, and at the same time increase the failure rate of hydraulic components, and increase the safety risk. Utility Model Content

[0003] The purpose of the utility model is to provide a starting line clamp type parking device which can reduce not only the manufacturing cost but also the operating cost, but also the failure rate of hydraulic components and the safety risk in view of the shortcomings of the prior art.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model to the starting line clamp type parking device is:

[0005] A clamp-type parking device to the starting line comprises brake rails on both sides of a basic rail, a plurality of transverse linkage rods are arranged below the brake rails, the transverse linkage rods penetrate the basic rails, a pair of guide sleeves fixedly connected to the basic rails are sleeved on the outer sides of the transverse linkage rods, a slide seat for installing the brake rails is sleeved on the outer sides of the guide sleeves, a reset mechanism is arranged between the brake rails and the basic rails, a first block is arranged on one side of the transverse linkage rod, a brake spring assembly is arranged between the first block and the slide seat on the same side, a slot is arranged on the other side of the transverse linkage rod, a second block is arranged in the slot, a longitudinal linkage rod is arranged between the second block and the slide seat on the same side, a protrusion cooperating with the second block is arranged on the longitudinal linkage rod, and a master oil cylinder fixedly connected to the brake rail on the same side is arranged at one end of the longitudinal linkage rod.

[0006] Preferably, the reset mechanism comprises a reset baffle plate fixedly connected to the brake rail, a guide pin is arranged between the reset baffle plate and the base rail, and a reset spring is sleeved on the outer side of the guide pin.

[0007] Preferably, the longitudinal linkage rod comprises a plurality of rectangular blocks corresponding to the slots one by one, adjacent rectangular blocks are connected as a whole by a connecting rod, and the protrusion is arranged on the side wall of the rectangular block.

[0008] Preferably, the first stopper is a pre-tightening nut, and a stopper is provided on one side of the transverse linkage rod adjacent to the warning nut, and the stopper and the pre-tightening nut cooperate to adjust the pre-tightening force of the brake spring assembly.

[0009] Preferably, the brake spring assembly comprises a pair of brake spring seats sleeved on the outer sides of the transverse linkage rod, and an inner spring and an outer spring are arranged between the two brake spring seats.

[0010] Preferably, the second stopper is a roller pivotally connected to the transverse linkage rod.

[0011] Preferably, a secondary cylinder fixedly connected to the brake rail on the same side is provided on the opposite side of the main cylinder for pushing the longitudinal linkage rod.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] The longitudinal linkage rod is driven by the main oil cylinder to move longitudinally in the slot. When the protrusion pushes the second stop block, the slide shrinks toward the basic rail. When the protrusion withdraws from the second stop block, the slide is reset under the action of the reset mechanism, thereby realizing the conversion between the braking position and the relief position. There is no need to configure multiple oil cylinders, which not only reduces the manufacturing cost, but also reduces the operating cost, while also reducing the failure rate of hydraulic devices, thereby reducing safety risks.

The outer side of the guide pin is sleeved with a reset spring 63, and the reset spring is located between the basic rail and the brake rail. The inner side of the transverse linkage rod (the side extending between the two basic rails) is arranged with a first block 31, and the first block is a pre-tightening nut. The transverse linkage rod is provided with a stopper 32 on one side of the warning nut, and a brake spring assembly 7 is installed between the stopper and the pre-tightening nut. The stopper and the pre-tightening nut are used to adjust the pre-tightening force of the brake spring assembly. The brake spring assembly includes a pair of brake springs sleeved on the outer side of the transverse linkage rod. The movable spring seat 71, the inner spring 72 and the outer spring 73 are installed between the two brake spring seats, the transverse linkage rod is located on the opposite side of the pre-tightening nut to open a slot 33, the slot is concave, and a second stopper 34 is arranged in the slot. The second stopper is a roller pivotally connected to the transverse linkage rod, and the roller passes through the slot. A longitudinal linkage rod 8 is arranged between the roller and the same side slide seat, and the longitudinal linkage rod includes a rectangular block 81 corresponding to the two slots one by one. The rectangular block slides in the concave slot, and the concave slot positions and guides the rectangular block. The two rectangular blocks are connected as a whole by a connecting rod 82. The side of the rectangular block The wall is integrally formed with a protrusion 83 that cooperates with the roller, and the protrusion is sloped. The roller can reduce the wear of the protrusion and extend its service life. The main cylinder 21 is arranged at the right end of the right rectangular block, and the cylinder body of the main cylinder is fixedly connected to the outer brake rail through a connecting plate, and the telescopic rod of the main cylinder is fixedly connected to the right rectangular block. The auxiliary cylinder 22 is arranged at the left end of the left rectangular block, and the cylinder body of the auxiliary cylinder is fixedly connected to the outer brake rail through a connecting plate, and the telescopic rod of the auxiliary cylinder is fitted with the left rectangular block. The auxiliary cylinder assists the main cylinder in pushing the longitudinal linkage rod. When the power of the main cylinder used is sufficient, the auxiliary cylinder may not be used.

[0022] The specific working process and principle of a clamp-type parking device to the starting line: when the relief position is converted to the braking position, the auxiliary oil cylinder assists the main oil cylinder to drive the longitudinal linkage rod to move to the right, the protrusion squeezes the roller to drive the transverse linkage rod to move outward, the brake spring seat pushes the inner slide to approach the basic rail, and at the same time, the rectangular block is subjected to the reaction force of the roller, driving the outer slide to approach the basic rail, and the return springs on both sides are compressed at the same time. When the wheel enters, it squeezes the brake rails on both sides. At this time, the inner and outer springs are compressed, which not only provides resistance for the inner slide to retreat, but also pulls the rectangular block through the transverse linkage rod to provide resistance for the outer slide to retreat, that is, the inner and outer springs simultaneously provide braking force for the brake rails on both sides to lock the wheels; when the braking position is converted to the relief position, the main oil cylinder drives the longitudinal linkage rod to move to the left, at this time, the extension of the auxiliary oil cylinder retracts in the power-off state, the protrusion withdraws from the slot, the squeezing force of the roller is reduced, the inner and outer springs and the return spring return to their original state, and the brake rails on both sides are away from the basic rail. The utility model drives the brake rail to approach or move away from the basic rail in a linkage manner, requires fewer power components (oil cylinders), reduces not only the manufacturing cost but also the operating cost, and also reduces the failure rate of the hydraulic device, thereby reducing the safety risk.
