Technical Field

[0001] The utility model belongs to the technical field of large environmental test chambers, and particularly relates to a dynamometer underground space support system. Background Art

[0002] An environmental test chamber is an enclosed indoor space for large equipment tests. For example, when conducting a vehicle dynamometer test under complex climatic conditions, the vehicle needs to be placed in the environmental test chamber to test the vehicle's performance by simulating various working conditions and environments.

Detailed implementation manners

[0029] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0030] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. 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 construed as a limitation to the present utility model.

[0031] It should be noted that a dynamometer underground space support system proposed in the present application should be arranged in the ground cabin 200 within the outer cabin 100, and its purpose is to support the dynamometer and the vehicle to be tested.

[0032] As Figures 1-3 shown, the specific solution of the embodiment is as follows: A dynamometer underground space support system includes two side plate frames 1 erected on both sides of the inner wall of the ground cabin 200, and a middle frame 2 erected in the middle of the ground cabin 200. A support column 11 for supporting on the inner bottom wall of the ground cabin 200 is provided at the bottom of the side plate frame 1. A diagonal bracing column 12 connected to the side wall of the support column 11 is provided at the bottom of the side plate frame 1 and on the side of the support column 11. Cross columns 21 inserted into the inner part of the inner wall of the ground cabin 200 are provided at both ends of the middle frame 2. Loading slots 3 are opened on the opposite sides of the side plate frame 1 and the middle frame 2, and a plurality of cover plates 8 are laid on the loading slots 3.

[0033] In this embodiment, the combined design of the side plate frame 1 and the middle frame 2 provides a stable three-dimensional support structure, ensuring the firm installation of the dynamometer in the underground space. The side plate frame 1 and the middle frame 2 respectively bear the lateral and longitudinal support forces, making the whole system more stable and reliable; the pillar 11 directly supports on the inner bottom wall of the ground cabin 200, enhancing the load-bearing capacity of the side plate frame 1; the diagonal strut 12 further enhances the lateral stability of the side plate frame 1, preventing overturning caused by lateral forces; the setting of the cover plate 8 protects the vehicle to be tested, and the independent design of the cover plate 8 facilitates the maintenance and replacement of the equipment; the independent design of components such as the side plate frame 1 and the middle frame 2 makes the maintenance and replacement of the system more convenient, reducing the maintenance cost and time.

[0034] Sound insulation pads in contact with the inner wall of the ground cabin 200 are provided on three sides of the side plate frame 1 close to the inner wall of the ground cabin 200. It effectively reduces the impact of the noise generated during the operation of the dynamometer on the external environment, improving the environmental protection performance and use comfort of the equipment.

[0035] The diagonal strut 12 below the side plate frame 1 faces the inner side wall of the ground cabin 200 close to the side frame plate. The layout of the diagonal strut 12 facing the inner side wall of the ground cabin 200 is more reasonable, which can more effectively resist lateral forces, further enhancing the stability of the side plate frame 1 without affecting the layout of the dynamometer.

[0036] A reinforcing anchor rod 13 extending to the ground under the ground cabin 200 is provided at the bottom of the pillar 11. The reinforcing anchor rod 13 extending to the ground under the ground cabin 200 enhances the connection strength between the pillar 11 and the bottom of the ground cabin 200, improving the load-bearing capacity and stability of the entire support system.

[0037] Furthermore, the length of the reinforcing anchor rod 13 is not less than one meter, one-third of the anchor rod is located on the inner bottom wall of the ground cabin 200, and the other two-thirds is inserted under the inner bottom wall of the ground cabin 200. At the same time, an insertion groove sleeved with the reinforcing anchor rod 13 is provided at the bottom end of the pillar 11. With such a design, not only the load-bearing capacity and stability of the entire support system are improved, but also it is more convenient to remove the side frame during the later maintenance of the side frame.

[0038] Optionally, as Figures 9-10 shown, a ground beam frame 14 is commonly provided at the bottom of all the pillars 11 at the bottom of the side plate frame 1, and a plurality of anchor feet 15 are provided at the bottom of the ground beam frame 14. In actual application, an embedded seat 16 is provided under the inner bottom wall of the ground cabin 200 through concrete, and the anchor feet 15 are connected to the embedded seat 16 through a plurality of bolts. Through the ground beam frame 14 and the anchor feet 15 connected to the ground cabin 200, the entire side plate frame 1 is more stably arranged in the ground cabin 200.

[0039] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、Figure 7 as well as Figure 8 As shown, in this embodiment, both the side frame 1 and the middle frame 2 are provided with a driving member 4 for driving the cover plate 8 to translate.

[0040] The driving member 4 comprises a motor 41 arranged on the side frame 1 or the middle frame 2, and a gear 42 is arranged on the output shaft of the motor 41.

[0041] The upper surfaces of both ends of the cover plate 8 are provided with driving grooves 81, and driving teeth 82 meshing with the gears 42 are provided in the driving grooves 81. The gears 82 driven by the motor 41 mesh with the driving teeth 82 on the cover plate 8, thereby realizing the automatic translation of the cover plate 8, and improving the convenience and efficiency of operation.

[0042] A gear 42 accommodating groove adapted to the gear 42 is provided on the side frame 1 or the middle frame 2 to accommodate the gear 42 therein.

[0043] like Figure 2 As shown, in this embodiment, both sides of the middle frame 2 and below the carrying groove 3 are provided with assembly grooves, and hydraulic rods 6 are provided on the side of the pillar 11 facing the middle frame 2 and below the carrying groove 3 and on the assembly grooves on both sides of the middle frame 2. The movable end of the hydraulic rod 6 is provided with a rolling ball 7, and the inner bottom wall of the carrying groove 3 is provided with a lifting groove 5 adapted to the rolling ball 7. When the hydraulic rod 6 is extended, the rolling ball 7 will pass through the lifting groove 5. The combination of the hydraulic rod 6 and the rolling ball 7 realizes the lifting of the cover plate 8 in the carrying groove 3, and the rolling ball 7 contacts the cover plate 8, thereby reducing the resistance of the cover plate 8 during translation.

[0044] It should be noted here that the height to which the cover plate 8 rises is less than the depth of the loading groove 3 . Therefore, even if the hydraulic rod 6 lifts up the cover plate 8 , the cover plate 8 will not separate from the loading groove 3 , thus ensuring the stability of the cover plate 8 when moving.

[0045] In addition, a mounting plate is installed at the movable end of the hydraulic rod 6, and rolling balls 7 are embedded in the mounting plate. The number of rolling balls 7 is greater than the number of cover plates 8. In practical applications, the length of the mounting plate is equal to the width of the cover plate 8, and no less than 3 rolling balls 7 are arranged on one mounting plate on average, so that the stability of the cover plate 8 when moving can be ensured, and the number of hydraulic rods 6 is less than the number of rolling balls 7.

[0046] like Figures 5-6 As shown, in this embodiment, the driving grooves 81 at both ends of the cover plate 8 are provided with oil drain grooves 83 which penetrate the driving grooves 81 along the width direction of the cover plate 8, so as to collect the lubricating oil required for the exhaust lubrication gear 42. In addition, a sound insulation board 84 is centrally arranged at the bottom of the cover plate 8 to isolate the noise of the dynamometer in the cabin 200.

[0047] Among them, the width of the sound insulation board 84 is equal to the width of the cover plate 8, and the length of the sound insulation board 84 is equal to the inner distance from the side frame to the middle frame 2. After the cover plate 8 is laid on the carrying groove 3, the side walls at both ends of the sound insulation board 84 are respectively connected to the side frame and the middle frame 2.

[0048] As Figures 7-8 shown, the working principle of the embodiment is as follows: After arranging the side frame and the middle frame 2 in the ground cabin 200, the dynamometer is set between the side frame and the middle frame 2. Part of the rotating hub of the dynamometer is exposed on the upper surface of the support system through the cover plate 8. After the vehicle to be tested drives in from the outer cabin 100 and passes through the cover plate 8 until the wheels of the vehicle to be tested move onto the rotating hub of the dynamometer exposed on the upper surface of the support system. When it is necessary to adjust the distance between each group of dynamometers, before the vehicle enters the outer cabin 100, start the hydraulic rod 6 to make the hydraulic rod 6 drive the rolling ball 7 to rise until it passes through the jacking groove 5 to lift the cover plate 8 and reduce the friction between the cover plate 8 and the carrying groove 3. Then start the motor 41, and the motor 41 drives the gear 42 to rotate, thereby applying a driving force to the cover plate 8 to make the cover plate 8 translate, so as to cooperate with the dynamometer to complete the distance adjustment.

[0049] 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.
