Description

Technical Field

[0001] The utility model relates to the technical field of sanitation cleaning vehicles, in particular to a front cleaning rack with an anti-collision function. Background Art

[0002] High-pressure cleaning vehicles use pipes and nozzles installed on the front cleaning rack device to spray high-pressure water to clean the road surface. The vehicle often operates along the edge of the road. The front cleaning rack is very likely to collide with obstacles such as shoulders and railings, causing damage to the front cleaning rack device and nozzles. The replacement and maintenance costs are high, reducing the cleaning efficiency. At the same time, the nozzle generates a large amount of water mist during operation, which will not only raise dust to pollute the environment, but also increase the driver's blind spot, posing a great safety hazard. Utility Model Content

[0005] The anti-collision component comprises an anti-collision plate, an anti-collision cover shell is arranged on the outer side of the anti-collision plate, and a water-blocking brush is arranged on the lower side of the anti-collision cover shell;

[0006] A reset component, connected to the anti-collision component, for resetting;

[0007] A mounting plate for connecting the reset assembly to the cleaning vehicle;

[0008] The detection device is used to detect the collision and feedback the signal.

[0009] The benefit of adopting the above technical solution is that the washing rack will be offset after a collision and automatically reset after crossing the obstacle. At the same time, it can feedback signals after a collision, reduce damage to the front washing rack device and nozzle, inhibit the generation of water mist, and reduce the driver's blind spot.

[0010] Furthermore, the reset assembly includes: a reset torsion spring, a connecting plate 1, a connecting plate 2 and a limiting shaft, the reset torsion spring is sleeved on the limiting shaft, and the protruding end abuts against two sides of the connecting plate 2, the connecting plate 1 is connected to the mounting plate, the connecting plate 2 is connected to the anti-collision assembly, and the limiting shaft is used to connect the connecting plate 1 and the connecting plate 2.

[0011] The benefit of adopting the above technical solution is that when a collision occurs, the anti-collision plate and the anti-collision cover are offset, and connecting plate 1 and connecting plate 2 rotate along the limit axis. At this time, the reset torsion spring is subjected to force. After crossing the obstacle, connecting plate 1 and connecting plate 2 are reset under the action of the reset torsion spring, and the anti-collision plate and the anti-collision cover are reset.

[0012] Furthermore, the reset assembly also includes a left limit bracket and a right limit bracket that are symmetrically arranged, and the extended end of the reset torsion spring is in contact with the left limit bracket and the right limit bracket.

[0014] Furthermore, the detection device includes a detection member installed on the side of the anti-collision plate and a detection bracket installed on the side of the mounting plate, and the detection member and the detection bracket are arranged opposite to each other.

[0015] The advantage of adopting the above technical solution is that after a collision, an offset occurs between the detection member and the detection bracket, and the detection member sends an offset signal to the vehicle, causing the vehicle to stop or avoid the collision.

[0016] Furthermore, a baffle is provided at the upper end of the limiting shaft, and the baffle is detachable.

[0017] The benefit of adopting the above technical solution is that the setting of the baffle prevents the return spring from axial movement and is used to fix the spring.

[0018] Furthermore, a front spray rod is arranged on the side of the anti-collision plate, a plurality of spray heads are arranged on the front spray rod, and the anti-collision cover shell covers the outer side of the front spray rod.

[0019] The benefit of adopting the above technical solution is that the anti-collision plate and the anti-collision cover play the role of installation and protection. When a collision occurs, they will not directly collide with the front spray boom, reducing the number of maintenance times.

[0020] Furthermore, the water-blocking brush is vertically arranged on the outside of the nozzle.

[0021] The benefit of adopting the above technical solution is that the provision of the water-retaining brush effectively prevents water mist from the nozzle, making it easier for the driver to observe the road conditions, while also having good passability, facilitating the passage of garbage and low obstacles.

[0022] Furthermore, the connecting plate 1 includes an upper plate and a lower plate, and the connecting plate 2 is rotatably disposed between the upper plate and the lower plate.

[0023] The advantage of adopting the above technical solution is that the setting of the upper plate and the lower plate plays a role of clamping and fixing, so that the anti-collision component connected to the second connecting plate can be rotated while maintaining the height position of the anti-collision component.

DETAILED DESCRIPTION

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 1-3 As shown, the utility model discloses a front cleaning rack with anti-collision function, comprising:

[0032] The anti-collision component comprises an anti-collision plate 1, an anti-collision cover 2 is arranged on the outer side of the anti-collision plate 1, and a water-blocking brush 3 is arranged on the lower side of the anti-collision cover 2;

[0033] A reset component 4, connected to the anti-collision component, for resetting;

[0034] A mounting plate 5, used to connect the reset assembly 4 to the cleaning vehicle;

[0035] The detection device is used to detect the collision and feedback the signal.

[0036] The benefit of adopting the above technical solution is that the washing rack will be offset after a collision and automatically reset after crossing the obstacle. At the same time, it can feedback signals after a collision, reduce damage to the front washing rack device and nozzle, inhibit the generation of water mist, and reduce the driver's blind spot.

[0037] In some embodiments, the reset assembly 4 may adopt the following structural scheme, the reset assembly 4 includes: a reset torsion spring 41, a connecting plate 1 42, a connecting plate 2 43 and a limiting shaft 44, the reset torsion spring 41 is sleeved on the limiting shaft 44, the extended end abuts against the two sides of the connecting plate 2 43, the connecting plate 1 42 is fixedly connected to the mounting plate 5, the connecting plate 2 43 is connected to the anti-collision assembly, the limiting shaft 44 is used to connect the connecting plate 1 42 and the connecting plate 2 43, and the connecting plate 2 43 and the connecting plate 1 42 can rotate around the limiting shaft 44. When a collision occurs, the anti-collision plate 1 and the anti-collision cover 2 are offset, and the connecting plates 1 42 and the connecting plates 2 43 rotate along the limiting shaft 44. At this time, the reset torsion spring 41 is stressed, and after crossing the obstacle, the connecting plates 1 42 and the connecting plates 2 43 are reset under the action of the reset torsion spring 41, and the anti-collision plate 1 is reset.

[0038] Furthermore, the reset assembly 4 further includes a left limit bracket 45 and a right limit bracket 46 that are symmetrically arranged, and the extended end of the reset torsion spring 41 contacts the left limit bracket 45 and the right limit bracket 46 .

[0039] When both sides of the anti-collision plate 1 and the anti-collision cover 2 are collided, the anti-collision plate 1 and the anti-collision cover 2 are offset to both sides, and the symmetrically arranged limit brackets preliminarily fix the two protruding ends of the reset torsion spring 41, so that the reset torsion spring 41 is in a balanced state when there is no collision.

[0040] In some embodiments, the detection device includes a detection member 6 installed on the side of the anti-collision plate 1 and a detection bracket 61 installed on the side of the mounting plate 5. The detection member 6 is arranged opposite to the detection bracket 61. The detection member 6 is fixed to the anti-collision plate 1 through an L-shaped plate. The detection member 6 is a displacement sensor or a distance sensor. When there is no collision, the detection member 6 is arranged opposite to the detection bracket 61. After a collision, the detection bracket 61 is offset. After detecting the offset of the detection bracket 61, the detection member 6 transmits a signal to the vehicle to stop or avoid the vehicle.

[0041] In some embodiments, a baffle 441 is provided at the upper end of the limiting shaft 44 , and the baffle 441 is detachable. The limiting shaft 44 is installed on the connecting plate 1 42 , and a return spring is sleeved thereon and then fixed by the baffle 441 .

[0042] The benefit of adopting the above technical solution is that the setting of the baffle 441 prevents the return spring from axial movement and is used to fix the spring.

[0043] In some embodiments, a front spray rod 7 is provided on the side of the anti-collision plate 1, and a plurality of spray heads are provided on the front spray rod 7. The anti-collision cover 2 covers the outside of the front spray rod 7, and the front spray rod 7 is connected to a water pipe to supply water to the spray heads.

[0044] The anti-collision plate 1 and the anti-collision cover 2 play the role of installation and protection. When a collision occurs, the front spray rod 7 will not be directly collided, thereby reducing the number of maintenance times.

[0045] Furthermore, the water-retaining brush 3 is vertically arranged outside the nozzle. The arrangement of the water-retaining brush 3 effectively prevents the nozzle from misting, facilitates the driver to observe the road conditions, and has good passability, and is convenient for garbage and low obstacles to pass through.

[0046] In some embodiments, the first connecting plate 42 includes an upper plate and a lower plate, and the second connecting plate 43 is rotatably arranged between the upper plate and the lower plate. The arrangement of the upper plate and the lower plate plays a clamping and fixing role, so that the anti-collision component connected to the second connecting plate 43 can rotate, and at the same time, the height position of the anti-collision component can be maintained.

[0047] During the working process, when the two sides of the washing rack encounter obstacles, the obstacles first contact the anti-collision cover 2 and the anti-collision plate 1. Under the action of the reset torsion spring 41, the anti-collision plate 1 rotates and deflects, driving the detection bracket 61 to deflect. The detection member 6 cannot detect the detection bracket 61. The vehicle can be emergency stopped or prompted to avoid through signal feedback. After crossing the obstacle, the reset torsion spring 41 drives the washing rack anti-collision plate 1 to reset. The anti-collision structure of the washing rack can realize automatic reset after a collision on the left and right sides, which has the following advantages:

[0048] 1. Anti-collision structure: the cleaning rack device is buffered and passively deflected after being subjected to external force, and automatically resets after crossing the obstacle. At the same time, the anti-collision cover 2 reduces the risk of damage to the front spray rod 7.

[0049] 2. Washing rack device position detection: external collision causes the washing rack device to shift, and the feedback signal can make the vehicle stop or avoid it.

[0050] 3. The fully surrounded design of the washing rack effectively suppresses the generation of water mist, facilitates observation of road conditions, and reduces environmental pollution. The brush design under the anti-collision cover 2 provides good passability.

[0051] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
