Description

Technical Field

[0001] The utility model relates to the technical field of automobile inspection equipment, in particular to an automatic wheel-blocking roller type automobile speed inspection platform. Background Art

[0002] Annual vehicle inspection is to inspect motor vehicles once a year to ensure the safety and environmental performance of the vehicle, and also to protect the safety of drivers and other road users. It is an important task. Vehicle inspection includes speed detection, which can check the accuracy of vehicle instruments. When testing the speed of automatic transmission wheels, it is necessary to use a speed test bench, suspend the car on the test bench, and let the wheel contact the roller installed on the test bench. The wheel drives the roller to rotate, and the output signal of the tachometer generator installed on the end of the roller shaft can be combined to effectively detect the vehicle speed.

[0003] In actual use, the existing automatic wheel-blocking roller-type automobile speed test bench usually requires the wheels to enter a high-speed rotation state. After the test, the brakes cannot be stepped on to avoid serious wear on the brake pads. The wheels need to be slowed down by themselves until they stop rotating, which can reduce the damage to the car. However, it takes more time to slow down the wheels by themselves. When there are many vehicles undergoing annual inspection, subsequent vehicles to be inspected will spend more time queuing, which significantly reduces the efficiency of vehicle inspection. In view of this, the present application proposes an automatic wheel-blocking roller-type automobile speed test bench that can quickly stop high-speed rotating vehicles and improve the efficiency of annual vehicle inspections. Summary of the invention

[0004] The utility model aims to solve the problem that it takes a lot of time for a vehicle to slow down automatically in the background technology, and proposes an automatic wheel-blocking drum type vehicle speed inspection station which can quickly stop a high-speed rotating vehicle and improve the efficiency of annual vehicle inspection.

[0005] The technical solution of the utility model: an automatic wheel-blocking roller-type automobile speed inspection bench, comprising a base, a supporting frame fixedly installed on the top of the base, a plurality of rollers rotatably installed on the supporting frame, a partition fixed inside the supporting frame, at least two partitions are provided, the rollers are rotatably installed between the inner side wall of the supporting frame and the partition, wherein one end of the roller shafts of the two rollers are jointly installed with a coupling, a lifting seat slidably installed between the inner side wall of the supporting frame and the partition, the lifting seat can brake the wheel after contacting it, and a speed reducer slidably installed on the top of the base, the speed reducer is used to control the lifting of the lifting seat.

[0006] Optionally, a first semi-arc plate is fixedly mounted on the lower surface of the lifting seat, and a second semi-arc plate is fixedly mounted on the top of the speed reducer.

[0007] Optionally, longitudinal slide grooves are bored on the inner side walls of the support frame and the inner walls of the partitions, and U-shaped connecting blocks are fixedly mounted on both ends of the lifting seat, and the U-shaped connecting blocks are slidably connected to the matching longitudinal slide grooves.

[0008] Optionally, a transverse sliding groove is bored at the top of the base, a sliding block is fixedly mounted at the bottom end of the speed reducer, and the sliding block is slidably connected to the transverse sliding groove.

[0009] Optionally, a speed brake opening is bored on the support frame, one end of the speed brake passes through the speed brake opening, a connecting plate is fixedly installed on the top of the speed brake, a cylinder is fixedly installed on the top of the base, and the output end of the cylinder is fixedly connected to the connecting plate.

[0010] Optionally, a rubber block is fixedly mounted on the top of the lifting seat, and a groove is provided on the top of the rubber block.

[0011] Optionally, a tachometer generator is fixedly installed between the two partitions, and one end of the roller shaft of one of the rollers is fixedly connected to the input end of the tachometer generator.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects: the lifting seat is lifted upward by the speed brake, and when the rubber block on the top of the lifting seat contacts the vehicle, the resistance encountered by the wheel when rotating can be increased. Without braking, the wheel can be quickly decelerated until it stops rotating, thereby reducing the time required for the wheel to switch from high-speed rotation to stop rotation, avoiding subsequent vehicles to be inspected from spending a lot of time queuing, and effectively improving the efficiency of annual vehicle inspections.

[0026] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example

[0027] like Figure 1-4 As shown, the automatic wheel-blocking roller-type automobile speed test bench proposed by the utility model comprises a base 1, a supporting frame 2 is fixedly installed on the top of the base 1, at least two partitions 4 are fixedly installed inside the supporting frame 2, a roller 3 is rotatably installed between the partition 4 and the inner side wall of the supporting frame 2, and the top of the roller 3 is higher than the top of the supporting frame 2, to ensure that the wheel will not contact the supporting frame 2 after being mounted on the two rollers 3, and then the roller 3 can be driven by the wheel to rotate stably; one end of the roller shaft of two rollers 3 is fixedly installed with a coupling to ensure that the four rollers 3 can maintain the same speed, a tachometer generator 9 is provided between the two partitions 4, and one end of the roller shaft of one of the rollers 3 is connected to the output of the tachometer generator 9 The input end is fixedly connected, and when the roller 3 drives the input shaft of the tachometer generator 9 to rotate, the tachometer generator 9 feeds back the input signal to the background terminal, so as to achieve the purpose of speed measurement; a lifting seat 6 is slidably installed between the inner wall of the supporting frame 2 and the partition 4, and a speed reducer 7 is slidably installed on the top of the base 1. A cylinder 8 fixed to the top of the base 1 is provided on one side of the speed reducer 7, and the output shaft of the cylinder 8 is fixedly connected to the connecting plate 71 on the top of the speed reducer 7. The cylinder 8 can drive the speed reducer 7 to move horizontally, so that the speed reducer 7 can be pushed to the bottom of the lifting seat 6, and the lifting seat 6 can be lifted upward. When the lifting seat 6 contacts the vehicle, the resistance to the high-speed rotating wheel can be increased, so that the wheel can be stopped quickly.

[0028] Furthermore, a first semi-arc plate 62 is fixedly installed at the bottom of the lifting seat 6, and a second semi-arc plate 72 is fixedly installed at the top of the speed reducer 7. When the speed reducer 7 moves to the bottom of the lifting seat 6, the second semi-arc plate 72 gradually contacts with the first semi-arc plate 62. When the two semi-arc plates are kept on the same vertical axis, the lifting seat 6 can be lifted to the maximum height. At this time, the rubber block 61 on the top of the lifting seat 6 contacts with the wheel, and the wheel sinks into the groove on the top of the rubber block 61, which can increase the resistance of the high-speed rotating wheel and ensure that the high-speed rotating wheel can be quickly braked to a stop.

[0029] Secondly, longitudinal grooves 12 are provided on the inner side walls of the support frame 2 and the inner walls of the partition 4, and U-shaped connecting blocks 63 are fixedly installed at both ends of the lifting seat 6. The above-mentioned U-shaped connecting blocks 63 are slidably connected to the longitudinal grooves 12, ensuring that the lifting seat 6 can be stably slidably installed inside the support frame 2, thereby improving its stability during lifting and lowering, and enhancing the stability of the lifting seat 6 when it contacts the wheels; a transverse groove 5 is opened on the top of the base 1, and a slider 73 is fixedly installed on the bottom of the speed reducer 7. The above-mentioned slider 73 is slidably connected to the transverse groove 5, effectively improving the stability of the speed reducer 7 during transverse movement.

[0030] Furthermore, a speed brake opening 11 is bored on the support frame 2, and the speed brake 7 passes through the speed brake opening 11, ensuring that the speed brake 7 can pass through the wall panel of the support frame 2 and move laterally, so as to facilitate the adjustment of the position of the speed brake 7.

[0031] In this embodiment, the wheel is first suspended on the top of the support frame 2 to ensure that the wheel can contact the roller 3. At this time, the bottom end of a single wheel is mounted between the two rollers 3. Under the action of the coupling, it is ensured that the four rollers 3 on the inspection table can rotate synchronously. When the wheel rotates, it can drive the four rollers 3 to rotate at the same speed; when the roller 3 drives the input shaft of the tachometer generator 9 to rotate, the tachometer generator 9 feeds back the input signal to the background terminal, so as to achieve the purpose of speed measurement; after the speed measurement test is completed, the speed reduction plate 7 is pushed to move horizontally by the cylinder 8. When the speed reduction plate 7 gradually moves to the bottom of the lifting seat 6, the first semi-arc plate 62 is pushed upward by the second semi-arc plate 72, and then it can be moved to The lifting seat 6 is lifted up. When the lifting seat 6 is lifted to the maximum height, the wheel is embedded in the groove at the top of the rubber block 61, and then the rubber block 61 increases the resistance of the high-speed rotating wheel, which can shorten the time taken for the wheel to change from a high-speed rotating state to a braked state. In this stage, the speed reducer 7 can be driven to reciprocate by the cylinder 8, so that the lifting seat 6 enters a reciprocating lifting state, and then the wheel and the rubber block 61 can be frequently in contact. Under the premise of ensuring deceleration, the damage to the wheel can also be reduced. The present application adopts an external brake structure, which can quickly stop the high-speed rotating wheel. When there are many vehicles for annual inspection, the queuing time of subsequent vehicles to be inspected can be reduced, which effectively improves the efficiency of vehicle annual inspection.

[0032] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
