Description

Technical Field

[0001] This invention relates to the field of automotive testing bench technology, and more particularly to a roller testing bench for automotive testing. Background Technology

[0002] Brake performance testing is an important indicator in vehicle annual inspection. Vehicle brake testing generally uses a roller-type reaction force vehicle brake testing bench. This bench primarily measures the tire slip rate by rotating the rollers as the tires rotate. Currently, existing roller-type vehicle testing benches typically consist of a low roller and a high roller, allowing the vehicle to stably undergo brake performance testing between the two rollers. As the core component for braking performance and driving force testing, the surface friction coefficient of the vehicle testing bench rollers directly affects the accuracy of the test data.

[0003] After prolonged use, the wear of the diamond abrasive on the roller assembly of a vehicle inspection bench leads to a decrease in the coefficient of friction. To save downtime, the industry commonly adopts an online abrasive replenishment process (i.e., application without disassembling the rollers). However, during the replenishment process, diamond abrasive can easily fall between the rollers into the interior of the inspection bench, affecting its use. Furthermore, during daily use, dirt, stones, and other debris adhering to the wheels can also easily fall into the interior of the inspection bench, making it difficult to clean.

[0004] Therefore, this application proposes a roller inspection table for automobile inspection that facilitates the collection and cleaning of impurities that fall inside the inspection table. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a roller inspection table for automobile inspection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A roller inspection table for automobile testing includes a housing and an adhesive cloth disposed inside the housing for collecting impurities. The adhesive cloth is laid below the roller and is laid inside the housing by a traction assembly. A support plate for supporting the adhesive cloth is fixed inside the housing. The support plate is a downwardly concave arc shape. The traction rod of the traction assembly adjusts its height during movement through two sets of guide components.

[0007] In some embodiments, the traction assembly includes a traction rod for traction of the adhesive fabric and two first telescopic rods for adjusting the height of the traction rod. The upper ends of the two first telescopic rods are fixed to both ends of the traction rod by two connecting plates, and the lower ends of the two first telescopic rods are provided with a transmission assembly for driving the first telescopic rods and the traction rod to move.

[0008] In some embodiments, a plurality of spikes are fixed below the traction rod, and a plurality of through grooves that cooperate with the spikes are provided on the surface of the support plate.

[0009] In some embodiments, the guiding assembly includes a guide wheel that rotates on the side of the upper end of the first telescopic rod away from the traction rod and a guide groove fixed to the inner wall of the housing. The guide wheel rolls inside the guide groove, and the guide groove follows the same trajectory as the support plate.

[0010] In some embodiments, the housing is provided with a cutting assembly for cutting the adhesive fabric. The cutting assembly is located near the inlet and includes a second guide rod fixed to the top of the housing by two second telescopic rods and a cutting blade that slides on the surface of the second guide rod.

[0011] In some embodiments, the cutting blade slides on the surface of a second guide rod via a moving block. The second guide rod is square and fixed to the lower ends of two second telescopic rods. The moving block and the cutting blade are driven to move by a second threaded post.

[0012] In some embodiments, the second threaded post rotates at the top of the housing via two connecting plates, the surface of the second threaded post is threaded with a threaded cap, and the second threaded post drives the moving block to move via a slide and a slider.

[0013] In some embodiments, the guide groove includes a movable part that follows the same arcuate trajectory as the support plate and a lifting part disposed near the inlet end of the guide groove. The lifting part is triangular and communicates with the movable part. The inner wall of the guide groove is rotatably provided with a baffle for allowing the guide wheel to enter the upper end of the lifting part.

[0014] In some embodiments, a vertical separation section is provided at one end of the guide groove near the outlet, the separation section being used to separate the barb from the adhesive fabric.

[0015] In some embodiments, the traction assembly pushes the cutting blade up through the avoidance assembly to avoid the movement trajectory of the traction rod. The avoidance assembly includes a horizontal crossbar fixed to the lower end of the second telescopic rod and a top block fixed to the upper surface of the first telescopic rod. The top block cooperates with the crossbar, and the length of the crossbar covers the width of the lifting portion.

[0016] Compared with the prior art, the present invention provides a roller inspection table for automobile inspection, which has the following beneficial effects.

[0017] 1. This invention, by setting up an adhesive cloth, uses a traction component to unfold the adhesive cloth under the roller with the adhesive side facing upwards. When sand replenishment is performed, the falling sand and gravel are adhered and collected by the adhesive cloth. After sand replenishment is completed, the used adhesive cloth is taken out through the outlet, achieving the purpose of easy cleaning. This avoids sand and gravel falling into the testing table and affecting its use. At the same time, during routine testing in the workshop, the adhesive cloth can also adhere and collect impurities falling from the wheels, preventing impurities from accumulating inside the testing table and affecting its service life.

[0018] 2. In this invention, by setting a cutting component, the cutting blade moves to cut the adhesive cloth, making it easy to remove the used adhesive cloth. By setting a guide component, collisions between the traction component and the cutting component can be avoided when the traction component moves near the inlet. By setting a lifting part of the guide groove, the traction rod moves upward under the trajectory of the lifting part. The upward movement of the traction rod can drive the barb to disengage from the through groove. Similarly, under the action of the lifting part, the guide wheel and the traction rod descend, so that the barb pierces into the adhesive cloth for traction of the adhesive cloth.

[0019] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Reference Figure 1-10 A roller inspection table for automobile inspection includes a housing 1 and an adhesive cloth 2 disposed inside the housing 1 for collecting impurities. The adhesive cloth 2 is laid below the roller 101. The upper surface of the housing 1 has an inlet 102 for inserting the adhesive cloth 2 and an outlet 103 for removing the adhesive cloth 2. Cover plates 104 are hinged to the surfaces of the inlet 102 and the outlet 103 respectively. The inlet 102 and the outlet 103 are located on both sides of the roller 101. The adhesive cloth 2 is a kraft paper coated with adhesive. The adhesive cloth 2 is placed inside the housing 1 through the inlet 102 in a rolled manner. The adhesive cloth 2 is laid inside the housing 1 by the traction component 4. A support plate 3 for supporting the adhesive cloth 2 is fixed inside the housing 1. The support plate 3 is a downwardly concave arc shape. An arc-shaped recess for placing the roll of adhesive cloth 2 is provided at one end of the support plate 3 near the inlet 102.

[0033] It is understandable that by setting up the adhesive cloth 2, the traction component 4 unfolds the adhesive cloth 2 below the roller 101 with the adhesive side facing upwards. When sand replenishment is performed, the falling sand is collected by the adhesive cloth 2. After sand replenishment is completed, the used adhesive cloth 2 is removed through the outlet 103, which facilitates cleaning and prevents sand from falling into the testing table and affecting its use. At the same time, during daily testing in the workshop, the adhesive cloth 2 can also collect impurities falling from the wheels, preventing impurities from accumulating inside the testing table and affecting its service life. By setting up the support plate 3, the adhesive cloth 2 is supported, and the support plate 3 is set in an arc shape, which can keep the adhesive cloth 2 in an arc shape, improve the collection effect of impurities, and prevent impurities from falling to the surroundings.

[0034] Specifically, the traction assembly 4 includes a traction rod 401 for traction of the adhesive fabric 2 and two first telescopic rods 403 for adjusting the height of the traction rod 401. The upper ends of the two first telescopic rods 403 are fixed to the two ends of the traction rod 401 by two L-shaped connecting plates. The first telescopic rods 403 are multi-stage telescopic rods. Multiple spikes 4011 are fixed below the traction rod 401, and multiple through slots 402 that cooperate with the spikes 4011 are opened on the surface of the support plate 3. The lower ends of the two first telescopic rods 403 are provided with a transmission assembly 404 for moving the first telescopic rods 403 and the traction rods 401. The transmission assembly 404 includes two first guide rods 4041 fixed to the inner wall of the housing 1 and a movable plate 4042 sliding on the surface of the two first guide rods 4041. A first threaded post 4043 is threadedly connected to the middle of the movable plate 4042. The first threaded post 4043 rotates on the inner wall of the housing 1, and the first threaded post 4043 and the two first guide rods 4041 are both located below the support plate 3. The first threaded post 4043 is driven to rotate by a drive motor. The two first telescopic rods 403 are respectively fixed to both ends of the movable plate 4042.

[0035] Understandably, by setting up the traction rod 401, the traction rod 401 is raised and lowered according to the first telescopic rod 403, thereby driving multiple spikes 4011 to penetrate one end of the adhesive cloth 2, so that the traction rod 401 can drive one end of the adhesive cloth 2 to move; by rotating the first threaded column 4043, the moving plate 4042 is driven to slide on the surface of the two first guide rods 4041, so that the moving plate 4042 drives the first telescopic rod 403 and the traction rod 401 to move above the support plate 3, thereby pulling one end of the adhesive cloth 2 from the inlet 102 of the housing 1 to the outlet 103, thereby facilitating the laying of the adhesive cloth 2; after the spikes 4011 penetrate the surface of the adhesive cloth 2, the spikes 4011 are inserted into the through groove 402. At this time, the adhesive cloth 2 is located between the support plate 3 and the traction rod 401, which can prevent the adhesive cloth 2 from detaching from the surface of the spikes 4011 when the traction rod 401 pulls the adhesive cloth 2 to move.

[0036] Specifically, the height of the traction rod 401 is adjusted by two sets of guide components 5 during the movement. The two sets of guide components 5 are located on the side of the two first telescopic rods 403 away from the traction rod 401. The guide component 5 includes a guide wheel 501 that rotates on the upper end of the first telescopic rod 403 away from the traction rod 401 and a guide groove 502 fixed to the inner wall of the housing 1. The guide wheel 501 rolls inside the guide groove 502, and the guide groove 502 has the same trajectory as the support plate 3.

[0037] Understandably, during the movement of the traction rod 401, the upper end of the first telescopic rod 403 slides against the guide groove 502 at all times through the guide wheel 501, thereby causing the first telescopic rod 403 to move up and down according to the trajectory of the guide groove 502, so that the traction rod 401 and the multiple spikes 4011 follow the arc trajectory of the support plate 3, maintaining the cooperation between the spikes 4011 and the through groove 402, and preventing the spikes 4011 from separating from the through groove 402 during the movement of the traction rod 401, which would cause the adhesive cloth 2 to fall off.

[0038] Specifically, two top cones 6 are fixed on both sides of the inner wall of the housing 1 to limit the roll of adhesive cloth 2. The top cones 6 are elastic telescopic structures, and the two top cones 6 are located below the inlet 102.

[0039] It is understandable that by setting two top cones 6, when installing the adhesive cloth roll 2, the two top cones 6 respectively abut against the inside of the roll in the center of the adhesive cloth roll 2, supporting the adhesive cloth roll 2, so that the adhesive cloth roll 2 can rotate and be laid under the roller 101.

[0040] Specifically, the housing 1 is equipped with a cutting assembly 7 for cutting the adhesive cloth 2. The cutting assembly 7 is located near the inlet 102. The cutting assembly 7 includes a second guide rod 701 fixed to the top of the housing 1 by two second telescopic rods 704 and a cutting blade 702 sliding on the surface of the second guide rod 701. The cutting blade 702 slides on the surface of the second guide rod 701 by a moving block 703. The second guide rod 701 is square and is fixed to the lower end of the two second telescopic rods 704. The moving block 703 and the cutting blade 702 are driven to move by a second threaded post 705. The second threaded post 705 rotates at the top of the housing 1 via two connecting plates. A threaded cap 706 is threadedly connected to the surface of the second threaded post 705. The second threaded post 705 drives the moving block 703 to move via the sliding groove 707 and the slider 708. One end of the second threaded post 705 is driven by a drive motor. A synchronous pulley is fixed to the end of the second threaded post 705 near the drive motor. Another synchronous pulley is fixed to one end of the output shaft of the drive motor. The two synchronous pulleys are connected by a synchronous belt. The height of the drive motor is higher than the height of the second threaded post 705.

[0041] Understandably, when the adhesive cloth 2 is finished and needs to be removed, the moving block 703 is driven by the second threaded post 705 to slide on the surface of the second guide rod 701, thereby causing the cutting blade 702 to move and cut the adhesive cloth 2, making it easy to remove the used adhesive cloth 2. By using a synchronous belt and synchronous pulley to drive the drive motor and the second threaded post 705, it is easy to raise the installation position of the drive motor to avoid the movement trajectory of the traction component 4.

[0042] Specifically, the guide groove 502 includes a moving part 5021 with the same arc-shaped trajectory as the support plate 3 and a lifting part 5022 provided at one end of the guide groove 502 near the inlet 102. The lifting part 5022 is triangular and connected to the moving part 5021. A vertical separating part 5023 is provided at one end of the guide groove 502 near the outlet 103. The separating part 5023 is used to separate the barb 4011 from the adhesive cloth 2. A baffle 5024 is rotatably provided on the inner wall of the guide groove 502 to allow the guide wheel 501 to enter the upper end of the lifting part 5022. The baffle 5024 is located at the junction of the lifting part 5022 and the moving part 5021. The upper end of the baffle 5024 rotates on the inner wall of the lifting part 5022, and the lower end of the baffle 5024 abuts against the bottom of the guide groove 502. The traction component 4 pushes the cutting blade 702 to rise through the avoidance component 8 to avoid the movement trajectory of the traction rod 401. The avoidance component 8 includes a horizontal bar 801 fixed at the lower end of the second telescopic rod 704 and a top block 802 fixed on the upper surface of the first telescopic rod 403. The top block 802 cooperates with the horizontal bar 801. The length of the horizontal bar 801 covers the width of the lifting part 5022. The two ends of the horizontal bar 801 and the surface of the top block 802 are respectively provided with rounded corners.

[0043] Understandably, to prevent the traction component 4 from colliding with the cutting component 7 when moving near the inlet 102, a clearance component 8 is provided to raise the cutting component 7, thereby facilitating the traction rod 401 to pass over the cutting blade and pull the adhesive cloth 2. When the traction component 4 moves to the lifting section 5022 via the guide wheel 501, the guide wheel 501 smoothly enters the top of the lifting section 5022 under the obstruction of the baffle 5024. Under the trajectory of the lifting section 5022, the second telescopic rod 704 and the top block 802... Simultaneously with the traction rod 401, the top block 802 can push the crossbar 801 upward, thereby causing the second telescopic rod 704 to retract, causing the cutting blade to move upward and avoid the traction rod 401. The upward movement of the traction rod 401 can cause the spike 4011 to disengage from the through groove 402, making it easier for the spike 4011 to pierce the adhesive cloth 2. When the guide wheel 501 slides inside the lifting part 5022, the top block 802 always remains in contact with the crossbar 801 to prevent the cutting blade from affecting the movement of the traction rod 401 after it descends and resets. When the guide wheel 501 moves to the end of the lifting part 5022 near the roll of adhesive cloth 2, the guide wheel 501 and the traction rod 401 descend, so that the barb 4011 pierces into the adhesive cloth 2 for pulling the adhesive cloth 2. When the traction rod 401 drives the adhesive cloth 2 to move towards the outlet 103, the guide wheel 501 slides at the bottom of the lifting part 5022. By pushing the baffle 5024 to rotate upward, the baffle 5024 avoids the guide wheel 501, so that the guide wheel 501 can slide smoothly into the moving part 5021. By setting the separation part 5023, when it is necessary to remove the adhesive cloth 2 from the housing 1, the guide wheel 501 is moved to the junction of the separation part 5023 and the moving part 5021. By lifting the traction rod 401 upward, the guide wheel 501 slides into the separation part 5023, separating the barb 4011 from the adhesive cloth 2, making it easier to remove the adhesive cloth 2.

[0044] Specifically, the height of the second threaded rod is higher than the telescopic end of the second telescopic rod 704. The slide groove 707 is fixed on the surface of the moving block 703. The slide groove 707 is U-shaped. The opening side of the slide groove 707 faces the threaded cap 706. The slider 708 is fixed on the side of the threaded cap 706 facing the slide groove 707. The slider 708 slides vertically on the inner wall of the slide groove 707.

[0045] Understandably, since the second guide rod 701 needs to be raised and lowered, the threaded cap 706 and the moving block 703 are slidably connected by the slider 708 and the groove 707. This allows the moving block 703 to remain connected to the threaded cap 706 when the second guide rod 701 and the cutting blade 702 are raised and lowered. When the threaded cap 706 moves, the slider 708 drives the groove 707 and the moving block 703 to move on the surface of the second guide rod 701, thereby allowing the cutting blade 702 to cut the adhesive cloth 2.

[0046] Specifically, a pressing assembly 9 for abutting one end of the adhesive fabric 2 is fixed between the two crossbars 801. The pressing assembly 9 includes a pressing roller 902 for abutting the adhesive fabric 2 and a fixing plate 901 for mounting the pressing roller 902. The fixing plate 901 is arc-shaped and is used to avoid the connecting plates at both ends of the traction rod 401. The pressing roller 902 rotates at the bottom of the fixing plate 901. A release film for preventing the adhesive fabric 2 from sticking is provided on the surface of the pressing roller 902.

[0047] Understandably, in order to facilitate the cutting of the adhesive cloth 2 by the cutting blade 702, a top pressure roller 902 is set to abut against the adhesive cloth 2. When the cutting blade 702 slides down to the lowest point, the top pressure roller 902 abuts against the surface of the adhesive cloth 2, pressing the adhesive cloth 2 against the surface of the support plate 3. This prevents the adhesive cloth 2 from deforming when the cutting blade 702 cuts it, thus facilitating the cutting process.

[0048] Specifically, a lifting plate 10 for raising the adhesive cloth 2 is fixed on the upper surface of the support plate 3. The lifting plate 10 is located at the junction of the two arc-shaped segments of the support plate 3.

[0049] It is understandable that by setting up the lifting plate 10, the adhesive cloth 2 between the lifting plate 10 and the top pressure roller 902 is lifted, so that it is separated from the support plate 3 and a gap is created, which makes it easier for the cutting blade 702 to cut the adhesive cloth 2.

[0050] In this invention, the adhesive fabric roll 2 is placed inside the housing 1 through inlet 102, with two top cones 6 respectively abutting against the center of the adhesive fabric roll 2, supporting the adhesive fabric roll 2 and facilitating its rotation. One end of the adhesive fabric roll 2 is placed on the surface of the support plate 3, causing the first threaded post 4043 to drive the moving plate 4042 and the first telescopic rod 403 to move, bringing the traction rod 401 closer to the adhesive fabric roll 2. Under the action of the lifting part 5022 of the guide groove 502, the baffle 5024 smoothly guides the guide wheel 501 into the top of the lifting part 5022. Under the trajectory of the lifting part 5022, the second telescopic rod 7... 04. The top block 802 and the traction rod 401 move up and down simultaneously. The top block 802 can push the crossbar 801 upward, thereby causing the second telescopic rod 704 to retract, making the cutting blade move upward to avoid the traction rod 401. The upward movement of the traction rod 401 can cause the spike 4011 to disengage from the through groove 402, making it easier for the spike 4011 to pierce the adhesive cloth 2. This causes the traction rod 401 to move towards the outlet 103, thereby laying the adhesive cloth 2 under the roll. When the traction rod 401 moves to the lower end of the separation section 5023, it is then retracted, thereby pulling out the allowance for the adhesive cloth 2 to adhere to the arc-shaped support plate 3. After retraction, The adhesive cloth 2 can adhere to the support plate 3. During sand replenishment work, the falling sand and gravel are collected and adhered by the adhesive cloth 2, thus preventing sand and gravel from falling into the testing platform and affecting its use. At the same time, during routine testing in the workshop, the adhesive cloth 2 can also collect and adhere impurities falling from the wheels, preventing impurities from accumulating inside the testing platform and affecting its service life. By periodically replacing the used adhesive cloth 2, the adhesiveness of the adhesive cloth 2 to the debris is maintained. When replacing the adhesive cloth 2, the guide wheel 501 is moved to the junction of the separation part 5023 and the moving part 5021, and the traction rod 401 is lifted upwards. The guide wheel 501 slides into the separation section 5023, separating the barb 4011 from the adhesive cloth 2. At the same time, the drive motor drives the second threaded column 705 to rotate, which in turn drives the moving block 703 to slide on the surface of the second guide rod 701. This causes the cutting blade 702 to move and cut the adhesive cloth 2, making it easy to remove the used adhesive cloth 2. A section of the cut adhesive cloth 2 remains on the surface of the support plate 3, which allows the barb 4011 of the traction rod 401 to penetrate and pull the adhesive cloth 2. The unused adhesive cloth 2 is then laid under the roller 101 for further collection of impurities.
