Description

Technical Field

[0001] The utility model belongs to the technical field of large-scale environmental test chambers, and in particular relates to a detachable cover plate of a dynamometer platform. Background Art

[0002] An environmental test chamber is an enclosed indoor space used for testing large equipment. For example, when conducting vehicle dynamometer tests in complex climate environments, it is necessary to place it in an environmental test chamber to test the vehicle's performance by simulating various working conditions and environments.

[0003] In order to make full use of the space and reduce noise, the dynamometer equipment in the environmental test chamber is installed in the underground space and arranged through support platforms. Cover plates are laid between the support platforms. When the vehicle is tested, it needs to be moved to the support platform so that the vehicle's wheels are directly on the dynamometer's hub.

[0004] However, different models have different numbers of wheels and wheel spacing. Therefore, when conducting dynamometer tests on different models, the spacing of the dynamometer needs to be adjusted. At this time, the cover plate laid on the support platform needs to be adjusted synchronously. However, in order to support such large vehicles, the cover plate will often be made of thicker special steel plates, which are more difficult to move. Summary of the Invention

[0005] The purpose of the utility model is to solve the problems existing in the prior art and provide a dynamometer platform with a detachable cover plate, which is convenient for adjusting the position of the cover plate and thus facilitates adjusting the spacing of the dynamometer.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a detachable cover plate of a dynamometer platform, comprising a load-bearing plate placed on a supporting platform, a sound insulation plate provided at the bottom of the load-bearing plate, silent plates provided at the bottom of the load-bearing plate and on both sides of the sound insulation plate, a rolling groove extending along the width direction of the load-bearing plate and passing through the silent plate is provided at the bottom of the silent plate, a driving groove extending along the width direction of the load-bearing plate and passing through the load-bearing plate is provided on both sides of the load-bearing plate, and a plurality of driving teeth are provided on the inner wall of the driving groove in the form of a linear array.

[0007] By setting up sound insulation boards and silent boards at the bottom of the load-bearing plate, noise can be effectively reduced. By setting up rolling grooves, driving teeth and driving grooves, the driving equipment on the supporting platform can conveniently drive the load-bearing plate to move, which is conducive to coordinating the adjustment of the dynamometer spacing.

[0008] Furthermore, the load-bearing plate is made of special steel, with a thickness of no less than 4 cm. Using special steel with a thickness of no less than 4 cm as the load-bearing plate material can significantly enhance the platform's load-bearing capacity and durability. Special steel plates generally have high strength and wear resistance, making them suitable for withstanding repeated loads and impacts, thereby extending the service life of the equipment.

[0009] Furthermore, the upper surface of the load-bearing plate is provided with a plurality of anti-skid grooves, which increases the safety of operators walking on the platform, prevents slipping accidents, and also prevents wheels of vehicles from slipping when walking.

[0010] Furthermore, the width of the supporting plate is equal to that of the sound insulation board, the length of the sound insulation board is shorter than that of the supporting plate, and the sound insulation board is centrally located relative to the supporting plate. This design, in which the sound insulation board is shorter than the length of the supporting plate and is centrally located, helps to more effectively focus the sound insulation effect on key areas while maintaining the platform's portability and cost-effectiveness.

[0011] Furthermore, the sound insulation board is a composite board composed of one or more of polyurethane porous board, high-density wood fiber board, and foam cement board. The flexibility of providing multiple material options, such as polyurethane porous board, high-density wood fiber board, and foam cement board, or their composite composites, allows users to select the most appropriate sound insulation solution based on specific application requirements and environmental conditions.

[0012] Furthermore, the rolling groove has an arcuate cross-section, vertically passing through the mute plate and extending into the interior of the bearing plate. This arcuate cross-section helps reduce friction and wear, allowing related components to move more smoothly, thereby improving the operating efficiency and lifespan of the equipment.

[0013] Furthermore, an oil drain groove is provided on the inner bottom wall of the drive groove and outside the drive teeth. This design facilitates the distribution of lubricating oil and the drainage of used oil, ensuring the cleanliness and lubrication of the drive system and reducing maintenance costs and time.

[0014] Furthermore, the oil drain groove is the same length as the drive groove and has an arc-shaped cross-section. This design allows the oil drain groove to fully receive lubricating oil flowing from the drive gear and support platform used to drive the cover plate, thereby reducing the amount of lubricating oil dripping into the space below the cover plate.

[0015] Furthermore, the support platform includes a side frame and a middle frame located in the middle of the side frame. The middle frame and the side frame are provided with a loading groove adapted to the supporting plate on the opposite side, and both ends of the side frame and the middle frame are provided with gears meshing with the driving teeth.

[0016] When the load-bearing plate is placed on the loading groove on the opposite side of the middle frame and the side frame, the installation is completed. If one of the cover plates needs to be removed, a crane with an electromagnetic lifter is used to suck the plate and lift it vertically. At the same time, when the motor drives the gear to rotate, the gear will drive the engaged load-bearing plate to move along the length of the support platform, thereby completing the translation of the cover plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. By arranging sound insulation panels and silent panels at the bottom of the load-bearing plate, noise can be effectively reduced. By arranging rolling grooves, driving teeth and driving grooves, the driving equipment on the supporting platform can conveniently drive the load-bearing plate to move, which is conducive to coordinating the adjustment of the dynamometer spacing; 2. A plurality of anti-skid grooves are provided on the upper surface of the load-bearing plate, which increases the safety of operators walking on the platform, prevents the occurrence of slipping accidents, and also prevents the wheels of the vehicle from slipping when walking; 3. An oil drain groove is provided on the inner bottom wall of the drive groove and outside the drive teeth. This design helps to distribute the lubricating oil and discharge the old oil, ensures the cleanliness and lubrication effect of the drive system, and reduces maintenance costs and time.

[0029] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] like Figure 1 —3, the specific scheme of the embodiment is as follows: a detachable cover plate of a dynamometer platform, comprising a bearing plate 1 placed on a supporting platform 8, a sound insulation plate 2 being provided at the bottom of the bearing plate 1, and silent plates 3 being provided at the bottom of the bearing plate 1 and on both sides of the sound insulation plate 2. By arranging the sound insulation plate 2 and the silent plate 3 at the bottom of the bearing plate 1, noise can be effectively reduced, a rolling groove 4 extending along the width direction of the bearing plate 1 and passing through the silent plate 3 is provided at the bottom of the silent plate 3, a driving groove 5 extending along the width direction of the bearing plate 1 and passing through the bearing plate 1 is provided on both sides of the bearing plate 1, and a plurality of driving teeth 6 are provided on the inner wall of the driving groove 5 in the form of a linear array.

[0032] like Figure 5-8As shown, the support platform 8 includes a side frame 81 and a middle frame 82 located in the middle of the side frame 81. The middle frame 82 and the side frame 81 are provided with a loading groove 811 adapted to the supporting plate 1 on the opposite side. The two ends of the supporting plate 1 are respectively placed on the two loading grooves 811 on the opposite side of the middle frame 82 and the side frame 81.

[0033] It should be noted here that the length of the sound insulation board 2 is adapted to the inner spacing between the middle frame 82 and the side frame 81. When the load-bearing plate 1 is placed on the supporting platform 8, the side surfaces at both ends of the sound insulation board 2 are in contact with the side walls on the opposite side of the middle frame 82 and the side frame 81, respectively, so as to ensure the sound insulation effect of the sound insulation board 2.

[0034] like Figure 9-10 As shown, gears 9 meshing with the driving teeth 6 are provided at both ends of the side frame 81 and the middle frame 82. At the same time, the side frame 81 and the middle frame 82 are also equipped with motors for driving the gears 9 to rotate.

[0035] When the position of the cover needs to be adjusted, the motor drives the gear 9 to rotate, and then applies transmission force to the drive tooth 6, so that the cover can be moved along the length direction of the support platform 8, thereby completing the adjustment of the cover, which is conducive to coordinating the adjustment of the dynamometer spacing. In addition, when a cover needs to be replaced, the electromagnetic lifter is used to absorb the cover, and then it is lifted vertically to remove the cover directly from the support platform 8.

[0036] In this embodiment, the load-bearing plate 1 is made of special steel plate, with a thickness of no less than 4 cm. Using a special steel plate with a thickness of no less than 4 cm as the load-bearing plate 1 significantly enhances the platform's load-bearing capacity and durability. Special steel plates typically have high strength and wear resistance, making them suitable for withstanding repeated loads and impacts, thereby extending the service life of the equipment.

[0037] It should be noted that a plurality of anti-skid grooves are provided on the upper surface of the load-bearing plate 1. The plurality of anti-skid grooves are provided on the upper surface of the load-bearing plate 1, which increases the safety of the operator walking on the platform, prevents the occurrence of slipping accidents, and also prevents the wheels of the vehicle from slipping when walking.

[0038] In this embodiment, the widths of the load plate 1 and the sound insulation board 2 are equal, the length of the sound insulation board 2 is shorter than that of the load plate 1, and the sound insulation board 2 is centrally located relative to the load plate 1. This design, in which the sound insulation board 2 is shorter than the length of the load plate 1 and is centrally located, helps to more effectively focus the sound insulation effect on key areas while maintaining the platform's portability and cost-effectiveness.

[0039] In this embodiment, the sound insulation board 2 is a composite board composed of one or more of polyurethane porous board, high-density wood fiberboard, and foam cement board. The flexibility of providing multiple materials, such as polyurethane porous board, high-density wood fiberboard, and foam cement board, or their composite composites, allows users to select the most appropriate sound insulation solution based on specific application requirements and environmental conditions.

[0040] like Figure 5 、 Figure 7 、 Figure 8 As shown, a hydraulic rod 10 is provided on the opposite side of the side frame 81 and the middle frame 82 and below the silent plate 3, and a rolling sleeve is provided at the movable end of the hydraulic rod 10, in which a rolling ball 11 is embedded, and a plurality of vertical lifting grooves 812 for passing through the side frame 81 or the middle frame 82 are evenly opened on the inner bottom wall of the mounting groove 811.

[0041] It should be noted that the number of hydraulic rods 10 is the same as the number of lifting slots 812, and they correspond one-to-one. When the hydraulic rods 10 are raised, the rolling balls 11 will leak out from the bottom of the lifting slots 812 until they lift the load plate 1 pressed against the loading slots 811. When the motor drives the gear 9 to drive the cover plate to translate, the contact between the rolling balls 11 and the load plate 1 greatly reduces frictional resistance compared to the contact between the silent plate 3 and the loading slots 811, making the cover plate move more easily.

[0042] like Figure 1 、 Figure 4 As shown, the rolling groove 4 has an arcuate cross-section, which vertically passes through the mute plate 3 and extends into the interior of the support plate 1. The arcuate cross-section of the rolling groove 4 allows the rolling ball 11 to be more stably released from the support plate 1, allowing related components to move more smoothly, thereby improving the operating efficiency and life of the equipment.

[0043] In this embodiment, an oil drain groove 7 is provided on the inner bottom wall of the drive groove 5 and outside the drive teeth 6. Providing the oil drain groove 7 on the inner bottom wall of the drive groove 5 and outside the drive teeth 6 facilitates the distribution of lubricating oil and the drainage of used oil, thereby ensuring the cleanliness and lubrication of the drive system and reducing maintenance costs and time.

[0044] like Figure 4 As shown, the oil drain groove 7 is the same length as the drive groove 5, and the cross-section of the oil drain groove 7 is arc-shaped. This design allows the oil drain groove 7 to fully receive the lubricating oil flowing out of the drive gear 6 and support platform 8 used to drive the cover plate, thereby reducing the amount of lubricating oil dripping into the space below the cover plate.

[0045] The working principle of the above embodiment is as follows: once the load plate 1 is placed on the loading slots 811 on the opposite side of the middle frame 82 and the side frame 81, the installation is completed. If one of the many cover plates needs to be removed, a crane with an electromagnetic lifting device can be used to suck the cover plate and lift it vertically directly.

[0046] like Figure 9 As shown, after the cover is removed, the motor closest to the vacant space is started, and the motor drives the gear 9 to rotate, and the gear 9 drives the carrier plate 1 meshed with it to move along the length direction of the support platform 8. When the cover moves, it will push the other covers in the direction of its translation to move synchronously until the vacant space is covered again, so that the spacing between the dynamometers can be adjusted. When the cover moves, the staff needs to add a cover behind the gear to ensure that the gear 9 does not idle.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
