Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices, in particular to a self-leveling auxiliary supporting device for a wheel load measuring instrument. Background Art

[0002] Vehicle wheel load measuring instruments are commonly used in vehicle center of mass measurement. They need to maintain a horizontal working state relative to the ground when measuring vehicle wheel loads. However, some experiments require measuring vehicle wheel loads on a platform that changes the height of the vehicle's center of mass or tilts forward at a certain angle. In this case, a self-leveling auxiliary support device is needed to level the wheel load measuring instrument, thereby facilitating vehicle wheel load measurements at a certain tilt angle.

[0003] At present, the self-leveling auxiliary support device is fixed with screws when installing the vehicle wheel load measuring instrument. Although this achieves the purpose of fixing, it is inconvenient to replace the vehicle wheel load measuring instrument during later replacement, which affects the work efficiency of workers. Therefore, it is necessary to design a self-leveling auxiliary support device for the wheel load measuring instrument. Utility Model Content

[0010] As a further description of the above technical solution:

[0011] The locking assembly includes a handle, a threaded rod and an extrusion block. The right side of the base is internally threaded with a threaded rod, one end of the threaded rod away from the swing arm is fixedly connected to the handle, and the end of the threaded rod close to the swing arm is rotatably connected to the extrusion block.

[0017] 1. Compared with the prior art, the self-leveling auxiliary support device of the wheel load measuring instrument is provided with a fixing component, a plug-in block and a first plug-in hole. When the vehicle wheel load measuring instrument needs to be replaced, the fixing component is used to release the fixation of the plug-in block. At this time, it is convenient to remove the plug-in block from the inside of the first plug-in hole, thereby facilitating the removal of the vehicle wheel load measuring instrument. In this way, the vehicle wheel load measuring instrument can be replaced, so that when the vehicle wheel load measuring instrument is replaced, there is no need to disassemble the bolts, thereby improving the work efficiency of the workers.

[0018] 2. Compared with the prior art, the self-leveling auxiliary support device of the wheel load measuring instrument is provided with a handle, a threaded rod and an extrusion block. By rotating the handle, the extrusion block can be driven to move toward the swing arm under the action of the threaded rod, or the extrusion block can be moved away from the swing arm.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1-6 The utility model provides a self-leveling auxiliary support device for a wheel load measuring instrument, comprising a base 1, wherein both sides of the upper end of the base 1 are fixedly connected with a rotating shaft 2, the circumferential surface of the rotating shaft 2 is rotatably connected with a swing arm 3, the upper end surface of the swing arm 3 is provided with a first plug hole 11, a plug block 13 is slidably connected inside the first plug hole 11, and a vehicle wheel load measuring instrument 4 is fixedly connected to the upper end of the plug block 13; a cavity 12 is provided inside the swing arm 3, a fixing component 5 is provided inside the cavity 12, and the fixing component 5 is used to fix the plug block 13; a locking component 7 is provided inside the right side of the base 1, and the locking component 7 is used to lock the swing arm 3.

[0029] Specifically, when installing the vehicle wheel load measuring instrument 4, align the plug-in block 13 with the first plug-in hole 11. At this time, the vehicle wheel load measuring instrument 4 can be preliminarily installed, and then the plug-in block 13 is fixed by the fixing component 5, so that the vehicle wheel load measuring instrument 4 is stably installed on the swing arm 3. When the vehicle wheel load measuring instrument 4 needs to be replaced, it is only necessary to use the fixing component 5 to release the fixation of the plug-in block 13. At this time, it is convenient to take out the plug-in block 13 from the inside of the first plug-in hole 11, so as to facilitate the removal of the vehicle wheel load measuring instrument 4. In this way, the vehicle wheel load measuring instrument 4 can be replaced, so that when the vehicle wheel load measuring instrument 4 is replaced, there is no need to remove the bolts, thereby improving the work efficiency of the workers; when the device needs to be transferred, the locking component 7 is used to lock the swing arm 3, which effectively prevents the swing arm 3 from rotating, which is conducive to the transfer of the device.

[0030] The fixing assembly 5 includes a rotating rod 501, a spring 502, a transmission rod 503 and a plug rod 504. The rotating rods 501 are rotatably connected to both sides of the cavity 12. The front end of the rotating rod 501 extends out of the swing arm 3. The spring 502 is fixedly connected between the two rotating rods 501. The side of the rotating rod 501 away from the spring 502 is rotatably connected to the transmission rod 503. The end of the transmission rod 503 away from the rotating rod 501 is rotatably connected to the plug rod 504. The plug rod 504 is slidably connected to the cavity 12; the plug block 1 The side end surface 3 is provided with a second plug hole 14, and the second plug hole 14 is slidably connected with the plug rod 504. When working, by pulling the rotating rod 501, the plug rod 504 can be driven away from the plug block 13 with the cooperation of the transmission rod 503, thereby releasing the limitation of the plug block 13, which is conducive to removing the vehicle wheel load measuring instrument 4. During the rotation of the rotating rod 501, the spring 502 will be compressed, and the compressed spring 502 is conducive to resetting the rotating rod 501.

[0032] The locking assembly 7 includes a handle 701, a threaded rod 702 and an extrusion block 703. The threaded rod 702 is connected to the internal thread on the right side of the base 1. The end of the threaded rod 702 away from the swing arm 3 is fixedly connected to the handle 701, and the end of the threaded rod 702 close to the swing arm 3 is rotatably connected to the extrusion block 703. When working, by rotating the handle 701, the extrusion block 703 can be driven to move toward the swing arm 3 under the action of the threaded rod 702, or the extrusion block 703 can be moved away from the swing arm 3. When the extrusion block 703 is close to the swing arm 3, the swing arm 3 can be squeezed and fixed, thereby effectively preventing the swing arm 3 from rotating, which is conducive to the transfer of the device.

[0033] Limiting holes 8 are provided on both sides of the base 1, and limiting columns 15 are slidably connected inside the limiting holes 8. The limiting columns 15 are fixedly connected to the swing arm 3. By setting the limiting holes 8 and the limiting columns 15, the swing arm 3 can be prevented from rotating excessively.
