Description

Technical Field

[0001] The utility model belongs to the technical field of large environmental test chambers, and particularly relates to a flip-up guard plate for a chassis dynamometer roller. Background Art

[0002] An environmental test chamber is an enclosed indoor space used for testing large equipment. For example, when conducting a dynamometer test on a vehicle under complex climatic conditions, the vehicle needs to be placed in the environmental test chamber to test its performance by simulating various working conditions and environments. For some special vehicles, such as large-tonnage military and civilian vehicles and equipment, emergency rescue vehicles, etc., large dynamometers and large chambers are used.

[0003] When the large dynamometer in this large chamber is not used for testing, in order to avoid unnecessary wear and tear on the dynamometer, strict protection measures should be taken. Especially for the roller part of the dynamometer, it should be avoided that sundries and dust enter the interior of the dynamometer through the gap on the support platform. At the same time, since this large chamber for large dynamometers usually has 6 - 8 or even more such rollers, but not all rollers are used every time. Therefore, when some rollers are not used, they should also be protected to prevent the vehicle under test from accidentally touching them. Based on such a situation, a flip-up guard plate for a chassis dynamometer roller is specifically proposed. Summary of the Invention

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and provide a flip-up guard plate for a chassis dynamometer roller, which covers the exposed part of the dynamometer when the dynamometer is not in use, so as to achieve the effect of protecting the roller of the dynamometer.

[0005] To achieve the above purpose, the utility model is realized by the following technical solutions: A flip-up guard plate for a chassis dynamometer roller, comprising a cover plate for covering the part of the dynamometer roller that leaks out of the surface of the support platform. One end of the cover plate is provided with a rotating seat, and the bottom of the rotating seat is provided with a mounting plate mounted on the support platform. The cover plate includes two straight plates. On the opposite sides of the two straight plates, inclined plates are provided. On the opposite sides of the two straight plates, a central reinforcing rib is provided. At the connection of the straight plate and the inclined plate, a turning reinforcing rib is provided. At both ends of the opposite sides of the two inclined plates, a first cross beam and a second cross beam are respectively provided. Both the first cross beam and the second cross beam are fixedly connected to the two straight plates. At the end of the two straight plates away from the mounting plate, a latching plate adapted to the support platform is provided.

[0006] By designing a guard plate structure including a cover plate, a rotating seat and a mounting plate, when the dynamometer is not in use, it can effectively cover and protect the exposed part of the dynamometer hub, preventing accidental touch and damage, thus improving the safety and service life of the equipment. When the covered dynamometer is needed, only the cover plate needs to be flipped up, and the operation is simple and fast.

[0007] Furthermore, the included angle between the straight plate and the inclined plate is between 150° and 165°. It can create a proper arch to perfectly cover the exposed part of the dynamometer hub. At the same time, it ensures that the cover plate can closely fit the support platform in the closed state, improving the sealing performance and protection effect.

[0008] Furthermore, the sides of the first cross beam and the second cross beam away from the straight plate are flush with the side of the inclined plate away from the straight plate. The design of the first cross beam and the second cross beam makes the overall appearance of the guard plate more harmonious and unified without a sense of abruptness in the closed state, and at the same time enhances the lateral stability of the guard plate.

[0009] Furthermore, the first cross beam is close to the rotating seat, and rounded arc surfaces are provided on both edge sides of the first cross beam away from the straight plate. The rounded arc surfaces are provided on the side of the first cross beam close to the rotating seat, reducing the friction between this part and the mounting plate during the rotation process, and improving the durability of the guard plate.

[0010] Furthermore, a lifting ring is provided at one end of the central reinforcing rib away from the rotating seat. The lifting ring provided on the central reinforcing rib facilitates the lifting operation of the guard plate when needed, improving the convenience of maintenance and replacement. In addition, this lifting ring can be connected to a winch installed on the wall of the test chamber, and the winch is used to retract and release the steel cable to realize the closing and opening of the cover plate.

[0011] Furthermore, a cable groove penetrating the length direction of the central reinforcing rib is provided in the middle of the side of the central reinforcing rib away from the first cross beam. This cable groove can be used for the steel cable to be naturally embedded in it when the cover plate is in the closed state, avoiding the problem that the steel cable is exposed and crushed by the test vehicle, thereby improving the service life of the steel cable.

[0012] Furthermore, the mounting plate is an "L" - shaped plate, and a plurality of mounting screw holes are provided on the mounting plate. The "L" - shaped mounting plate design, combined with a plurality of mounting screw holes, makes the installation process of the guard plate simpler and faster, and at the same time improves the installation stability.

[0013] Furthermore, the rotating seat includes a rotating plate installed at the bottom of the straight plate. Rotating shafts are installed on both sides of the rotating plate. The rotating seat further includes two fixing plates installed on the top of the mounting plate and located on both sides of the rotating plate. The rotating shafts pass through the fixing plates movably and are rotatably connected to the fixing plates, ensuring that the cover plate can rotate smoothly and steadily during the flipping process, reducing the risk of damage caused by friction or jamming.

[0014] Furthermore, at one end of the two straight plates away from the mounting plate, there is a latching plate adapted to the support platform. When closing the cover plate, the latching plate is placed on the middle of the support platform, further enhancing the bearing strength of the cover plate and making the cover plate not easily deformed.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. By designing a guard plate structure including a cover plate, a rotating seat and a mounting plate, when the dynamometer is not needed, it can effectively cover and protect the exposed part of the dynamometer hub, preventing accidental touch and damage, thereby improving the safety and service life of the equipment. When the covered dynamometer is needed, only the cover plate needs to be flipped up, and the operation is simple and fast; 2. The included angle between the straight plate and the inclined plate is between 150° and 165°, which can create a proper arch to perfectly cover the exposed part of the dynamometer hub. At the same time, it ensures that the cover plate can closely fit the support platform in the closed state, improving the sealing performance and protection effect; 3. The design of the first cross beam and the second cross beam makes the overall appearance of the guard plate more harmonious and unified without a sense of abruptness in the closed state, while enhancing the lateral stability of the guard plate.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0025] In this embodiment, a rotatable and flipable guard plate for the roller of a chassis dynamometer is installed on the support platform 11. On the support platform 11, two rows of movable plates 12 extending along the length direction of the support platform 11 are symmetrically laid. Some of the movable plates 12 are provided with openings, and a part of the roller of the dynamometer 13 is exposed from this opening for contacting the wheels of the test vehicle.

[0026] As Figure 1 —shown in FIG. 4, the specific solution of the embodiment is as follows: A rotatable and flipable guard plate for the roller of a chassis dynamometer includes a cover plate 1 for covering the part of the roller of the dynamometer 13 that leaks out of the surface of the support platform 11. The length of the cover plate 1 is adapted to the length of the movable plate 12. One end of the cover plate 1 is provided with a rotating seat 2, and the bottom of the rotating seat 2 is provided with a mounting plate 3 installed on the support platform 11. The cover plate 1 includes two straight plates 101. On the opposite sides of the two straight plates 101, inclined plates 102 are provided. On the opposite sides of the two straight plates 101, a central reinforcing rib 4 is provided. At the connection of the straight plate 101 and the inclined plate 102, a transition reinforcing rib 5 is provided. At both ends of the opposite sides of the two inclined plates 102, a first cross beam 6 and a second cross beam 7 are respectively provided. Both the first cross beam 6 and the second cross beam 7 are fixedly connected to the two straight plates 101.

[0027] In this embodiment, in order to ensure the overall strength of the cover plate 1, the two straight plates 101, the central reinforcing rib 4, the two inclined plates 102, and the two turning reinforcing ribs 5 are integrally formed. At the same time, the lengths of the central reinforcing rib 4 and the turning reinforcing rib 5 are both equal to the length of the straight plate 101.

[0028] By designing a guard plate structure including the cover plate 1, the rotating seat 2, and the mounting plate 3, when the dynamometer 13 is not needed, the exposed part of the rotating hub of the dynamometer 13 can be effectively covered and protected, preventing accidental touch and damage, thereby improving the safety and service life of the equipment. When the covered dynamometer 13 needs to be used, the cover plate 1 can be simply flipped up, and the operation is simple and fast.

[0029] As Figure 4 shown, in this embodiment, the first cross beam 6 is close to the rotating seat 2, and rounded arc surfaces are provided on both side edges of the side of the first cross beam 6 away from the straight plate 101. The rounded arc surface is provided on the side of the first cross beam 6 close to the rotating seat 2, reducing the friction between this part and the mounting plate 3 during the rotation process and improving the durability of the guard plate.

[0030] As Figure 2 shown, the rotating seat 2 includes a rotating plate installed at the bottom of the straight plate 101. Rotating shafts are installed on both sides of the rotating plate. It also includes two fixing plates installed on the top of the mounting plate 3 and located on both sides of the rotating plate. The rotating shafts pass through the fixing plates movably and are rotatably connected to the fixing plates. A cover plate 1 is symmetrically provided with two rotating seats 2 centered on the central reinforcing rib 4, ensuring that the cover plate 1 can rotate smoothly and stably during the flipping process, reducing the risk of damage caused by friction or jamming.

[0031] As Figure 1 shown, at one end of the two straight plates 101 away from the mounting plate 3, there is a latching plate 8 adapted to the support platform 11. When the cover plate 1 is closed, the latching plate 8 is latched on the middle of the support platform 11, further strengthening the bearing strength of the cover plate 1 and making the cover plate 1 not easily deformed.

[0032] As Figure 5 shown, in this embodiment, the included angle between the straight plate 101 and the inclined plate 102 is between 150° and 165°. Such a design can create a suitable arch, thus perfectly covering the exposed part of the rotating hub of the dynamometer 13. At the same time, it ensures that the cover plate 1 can closely fit the support platform 11 in the closed state, improving the sealing performance and protection effect.

[0033] In addition, the sides of the first cross beam 6 and the second cross beam 7 away from the straight plate 101 are flush with the side of the inclined plate 102 away from the straight plate 101. The design of the first cross beam 6 and the second cross beam 7 makes the overall appearance of the guard plate more harmonious and unified without a sense of abruptness in the closed state, and at the same time enhances the lateral stability of the guard plate.

[0034] AsFigure 4 , Figure 6 As shown in Figure 6 , a lifting ring 9 is provided at one end of the central reinforcing rib 4 away from the rotating seat 2. The lifting ring 9 provided on the central reinforcing rib 4 facilitates the lifting operation of the guard plate when needed, improving the convenience of maintenance and replacement. In addition, this lifting ring 9 can be connected to a winch installed on the wall of the test chamber, and the winch is used to retract and release the steel cable to realize the closing and opening of the cover plate 1.

[0035] Furthermore, for the equipment to flip the cover plate 1, in addition to the above-mentioned winch steel cable traction method, a motor can also be directly installed on the mounting plate 3, and the output shaft of the motor is directly connected to the rotating shaft in the rotating seat 2. The motor drives the rotating shaft to rotate, thereby completing the closing and opening of the cover plate 1.

[0036] As Figure 2 , Figure 3 As shown in Figure 3 , a cable groove 10 penetrating the length direction of the central reinforcing rib 4 is opened in the middle of the side of the central reinforcing rib 4 away from the first cross beam 6. This cable groove 10 can be used for the steel cable to be naturally embedded therein when the cover plate 1 is in the closed state, avoiding the problem that the steel cable is exposed and crushed by the test vehicle, thereby extending the service life of the steel cable.

[0037] The mounting plate 3 is an "L"-shaped plate, and a plurality of mounting screw holes are opened on the mounting plate 3. The design of the "L"-shaped mounting plate 3, combined with a plurality of mounting screw holes, makes the installation process of the guard plate simpler and faster, and also improves the installation stability.

[0038] The working principle of the above embodiment is as follows: When the dynamometer 13 is needed, the cover plate 1 is flipped up. When the dynamometer 13 is not needed, the cover plate 1 is flipped down, and the bridging plate 8 is placed on the middle bench of the support platform 11. The first cross beam 6 and the second cross beam 7 are in contact with the movable plate 12. Using the arched structure supported by the inclined plate 102, the cover plate 1 covers all the rotating hub parts of the dynamometer 13 exposed on the surface of the support platform 11.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
