Description

Technical Field

[0001] The utility model relates to the field of weighbridges, in particular to a weighbridge with a shock absorption device. Background Art

[0002] A weighbridge, also known as a truck scale, is a large weighing scale set on the ground, usually used to weigh the cargo tons of trucks. It is the main weighing equipment for factories, mines, merchants, etc. to measure bulk goods. Weighbridges can be classified according to the scale body structure into: I-beam weighbridges, T-beam weighbridges, L-beam steel weighbridges, U-shaped steel weighbridges, channel steel weighbridges, and reinforced concrete weighbridges; and can be classified according to the sensor type into digital weighbridges and analog weighbridges.

[0003] The Chinese utility model patent with the publication number CN211013218U discloses a weighbridge with a shock absorption device. The invention improves the shock absorption effect by setting a shock absorption plate and hydraulic oil in the shock absorption cavity. However, the invention only focuses on the shock absorption in the vertical direction. When a vehicle drives onto the weighing platform and usually needs to brake and stop, the inertia brought by the vehicle braking will cause the weighing platform to shake horizontally. Since the weighbridge lacks equipment for horizontal shock absorption of the weighing platform, this shaking force will bring a large acting force to the sensor at the bottom of the weighing platform, increasing the probability of its damage to a certain extent; and generally, there is a certain gap between the guiding slope and the weighbridge to reserve a buffer space for the above situation. The size of this gap is generally set within the range of 5 - 6 cm, and this gap often leaves an access passage for mice, making it extremely easy for mice to build nests at the bottom of the weighbridge. The mice at the bottom of the weighbridge will bite the sensor, resulting in the damage of the weighbridge. Content of the Utility Model

[0032] Please refer to Figures 1 to 3 , the present utility model provides a weighbridge with a shock absorption device, including a weighbridge body 2, a guide slope 1, a horizontal shock absorber 6 and a vertical shock absorber 4;

[0033] There are two groups of guide slopes 1, which are symmetrically arranged at both ends of the weighbridge body 2 from left to right. A docking groove 11 is opened on the side of the guide slope 1 close to the weighbridge body 2;

[0034] The horizontal shock absorber 6 is installed in the docking groove 11;

[0035] A connecting protrusion 7 corresponding to the docking groove 11 is arranged at the end of the weighbridge body 2. The connecting protrusion 7 is installed in the docking groove 11 and is connected to the horizontal shock absorber 6;

[0036] There are multiple vertical shock absorbers 4, all of which are installed at the bottom of the weighbridge body 2.

[0037] Among them, the docking groove 11 has a strip-shaped structure. After the connecting protrusion 7 enters the docking groove 11, the gap between the weighbridge body 2 and the guide slope 1 is covered;

[0038] During use, when the weighbridge body 2 realizes rapid docking with the guide slope 1 through the connecting protrusion 7, the horizontal shock absorber 6 in the docking groove 11 can damp the vibration of the weighbridge body 2 in the horizontal direction. And after the connecting protrusion 7 enters the docking groove 11, the gap between the weighbridge body 2 and the guide slope 1 is covered, which can prevent mice from entering the bottom of the weighbridge through the gap between the weighbridge body 2 and the guide slope 1 to build nests. The vertical shock absorber 4 can damp the vibration of the weighbridge body 2 in the vertical direction, realizing effective shock absorption of the weighbridge and prolonging the service life of the weighbridge.

[0039] In this embodiment, there is a gap between the connecting protrusion 7 and the bottom of the inner wall of the docking groove 11. When the vehicle enters above the weighbridge body 2, the weighbridge body 2 is subjected to a downward pressure, and the gap between the connecting protrusion 7 and the bottom of the inner wall of the docking groove 11 is used to reserve a buffer space for the above situation.

[0040] In this embodiment, the contact surface between the horizontal shock absorber 6 and the connecting protrusion 7 is set to be smooth.

[0041] In this embodiment, the horizontal shock absorber 6 includes a bottom plate, a top plate, a damper assembly, and a shock-absorbing spring. The bottom plate and the top plate are respectively arranged at both ends of the damper assembly. The shock-absorbing spring is sleeved on the damper assembly, and both ends of the shock-absorbing spring are respectively connected to the bottom plate and the top plate; the vertical shock absorber 4 has the same structure as the horizontal shock absorber 6.

[0042] In this embodiment, it further includes a base 3 and a weighing sensor 5. The base 3 is arranged below the weighbridge body 2, and the weighing sensor 5 is installed between the weighbridge body 2 and the base 3.

[0043] The working principle of the present utility model is as follows:

[0044] While the weighbridge body 2 realizes the rapid docking with the guiding slope 1 through the connecting protrusion 7, the horizontal shock absorber 6 in the docking groove 11 can damp the vibration of the weighbridge body 2 in the horizontal direction. After the connecting protrusion 7 enters the docking groove 11, the gap between the weighbridge body 2 and the guiding slope 1 is covered, which can prevent mice from entering the bottom of the weighbridge through the gap between the weighbridge body 2 and the guiding slope 1 to build nests. The vertical shock absorber 4 can damp the vibration of the weighbridge body 2 in the vertical direction, realizing effective damping of the weighbridge and extending the service life of the weighbridge.
