UTILITY MODEL CONTENT
[0004] The utility model aims at overcoming the technical problems in the prior art that the vehicle is prevented from slipping by inserting bricks or stones between the wheels and the ground, but it is difficult to find bricks or stones that meet the requirements, and there is a safety hazard of crushing the operator by the wheels, and provides an anti-slip device and sanitation vehicle.
[0005] In the first aspect, the utility model provides an anti-slip device, comprising:
[0006] The swing arm is connected to the vehicle body at one end and provided with an inclined spacer at the other end;
[0007] The inclined spacer is provided with an inclined section on the side close to the wheels along the swing direction of the swing arm, and the closer to the wheels, the smaller the thickness of the inclined section;
[0008] The swing arm can swing to a first position and a second position; when the swing arm swings to the first position, the inclined section can be inserted between the wheels and the ground; when the swing arm swings to the second position, the inclined section can be withdrawn from between the wheels and the ground.
[0009] The present scheme uses a swing arm to connect the inclined pad to the vehicle body. When the vehicle body needs to be stopped on an inclined surface, the swing arm is swung to the first position, so that the inclined section of the inclined pad is inserted between the wheels and the ground. On the one hand, the rotation freedom of the wheels is limited, and on the other hand, the contact area between the vehicle body and the ground is increased, thereby preventing the vehicle body from sliding on the inclined surface. The thickness of the inclined section decreases as it approaches the wheels, so that it can be easily inserted between the wheels and the ground. When the vehicle body needs to run freely, the swing arm is swung to the second position, so that the inclined section of the inclined pad is withdrawn from between the wheels and the ground, thereby removing the limitation on the rotation freedom of the wheels, and the inclined pad does not hinder the free running of the vehicle body.
[0010] As can be seen from the above, the present scheme can limit the rotation freedom of the wheels and increase the contact area between the vehicle body and the ground, or remove the limitation on the rotation freedom of the wheels and restore the contact area between the vehicle body and the ground, by swinging the swing arm to insert or withdraw the inclined section between the wheels and the ground, so that the vehicle body can be smoothly parked on the inclined surface or run freely, and the operator does not need to search for bricks or stones that meet the requirements. When operating, the operator only needs to operate the swing arm, without the need to stretch his hand between the wheels and the ground as in the prior art, thereby eliminating the safety hazard of the wheels rolling over the operator.
[0011] Preferably, the inclined pad is swingably connected to the swing arm, and the swing axis of the inclined pad is parallel to the swing axis of the swing arm.

[0013] Preferably, the number of swing arms is greater than one, and the swing arms are spaced apart along the length direction of the inclined pad.
[0014] The present scheme can combine the swing arm, the inclined pad and the vehicle body into a multi-link mechanism, such as a double rocker mechanism or a crank rocker mechanism, so that the inclination angle of the inclined pad can be linked with the swing angle of the swing arm, which is conducive to achieving the required movement mode of the inclined pad by adjusting the length and initial angle of each swing arm and the inclined pad. For example, the lengths of the swing arms are the same, and the swing arm, the inclined pad and the vehicle body are combined into a parallelogram mechanism, so that the inclination angle of the inclined pad is always parallel to the direction of the vehicle body, thereby reducing the vertical space occupied by the inclined pad in the second position and preventing the inclined pad from negatively affecting the passability of the vehicle body.
[0015] Preferably, the present scheme further comprises a driving device connected to the swing arm, and the driving device is used to drive the swing arm to swing from the first position to the second position, and / or from the second position to the first position.
[0016] The scheme recommends adding a driving device to the swing arm, which can realize automatic swing of the swing arm, further reduce the safety risk of the operation of clamping the inclined section between the wheel and the ground, and reduce the human consumption of the operation.
