Description

Technical Field

[0001] The utility model relates to the technical field of special vehicles for sanitation, in particular to a sanitation vehicle with an anti-collision buffer structure. Background Art

[0002] With the rapid development of urban roads and vehicles, and the improvement of people's requirements for living environment, the demand for road cleaning is becoming more and more urgent. Various types of road cleaning vehicles for urban roads, square streets, and high-grade highways continue to appear in people's vision. Using road sweepers to replace sanitation workers to clean the road has become a mainstream method.

[0003] Since the speed of the sweeper is relatively slow during operation, there is a large speed difference between the operating vehicle and the public vehicles, especially on highways, ring roads and other roads with high speeds, large traffic volume and complex road conditions. The rear vehicle is very likely to rear-end the sweeper, causing great damage to personnel and vehicles. Therefore, anti-collision buffer devices have become a common configuration of sweepers. The installation of anti-collision devices can effectively reduce the damage to personnel and vehicles after a rear-end collision. Anti-collision buffer devices generally have two states: vertical and horizontal. When the sweeper is transported, the anti-collision buffer device is in a vertical state, and when the sweeper is performing a cleaning operation, the anti-collision buffer device is in a horizontal state. However, when the existing anti-collision buffer devices are in two states, there is a risk of swinging or even falling, and the safety is poor. Utility Model Content

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] In the existing technology, traditional road sweepers are mostly operated with sound and light warnings, or followed by a special anti-collision buffer vehicle, which increases the risk of rear-end collision and the cost of highway sweeping operations. The installation of anti-collision buffer devices needs to solve the two states of operation and transportation. The anti-collision pad is in a vertical state during transportation and in a horizontal state during operation. The flip structure causes the anti-collision pad to swing or even fall during use.

[0030] In order to solve the above problems, refer to Figures 1 to 9 As shown, the utility model provides a sanitation vehicle with an anti-collision buffer structure, and the sanitation vehicle with the anti-collision buffer structure comprises: a vehicle body 10, a fixed seat 11 is arranged at the rear of the vehicle body 10; an anti-collision buffer structure 20, which is flipably mounted on the fixed seat 11, and the anti-collision buffer structure 20 comprises an anti-collision buffer body 21, a first driving structure 22, a first locking structure 23 and a second locking structure 24, the anti-collision buffer body 21 has a protection position and a transfer position, and the first driving structure 22 is used to drive the anti-collision buffer body 21 to flip so that the anti-collision buffer body 21 switches between a protection position and a transfer position; a first locking mechanism 30 is installed on the vehicle body 10 and is located at the rear of the vehicle body 10; and a second locking mechanism 40 is installed at the bottom of the vehicle body 10. When the anti-collision buffer body 21 is in the transfer position, the first locking mechanism 30 cooperates with the first locking structure 23 to fix the anti-collision buffer structure 20 in the transfer position. When the anti-collision buffer body 21 is in the protection position, the second locking mechanism 40 can cooperate with the second locking structure 24 to fix the anti-collision buffer structure 20 in the protection position.

[0031] In this embodiment, when the anti-collision buffer body 21 is in the protection position, it can play a buffering role when the rear vehicle rear-ends, reduce the damage to the vehicle body 10 and the rear-end vehicle, ensure the safety of vehicle operation, and reduce personal and property losses. The anti-collision buffer structure 20 is flipped on the fixed seat 11. When the cleaning operation is required, the first driving structure 22 drives the anti-collision buffer body 21 to flip to the protection position. When the anti-collision buffer body 21 flips to the protection position, the second locking mechanism 40 cooperates with the second locking structure 24 to lock the anti-collision buffer structure 20 in the protection position. When the sweeper does not perform cleaning, the first driving structure 22 drives the anti-collision buffer body 21 to flip to the transfer position. When the anti-collision buffer body 21 flips to the transfer position, the first locking mechanism 30 cooperates with the first locking structure 23 to lock the anti-collision buffer structure 20 in the transfer position. Through the cooperation between the first locking mechanism 30 and the first locking structure 23, and the cooperation between the second locking mechanism 40 and the second locking structure 24, the anti-collision buffer structure 20 can be locked in the transfer position or the protection position, avoiding the risk of the anti-collision buffer structure 20 swinging or even falling in the transfer position and the protection position, thereby improving the safety of the sanitation vehicle with the anti-collision buffer structure.

[0032] It should be noted that the vehicle body 10 has the structure of a conventional street sweeper, which will not be described in detail herein.

When the anti-collision buffer body 21 is in the transfer position, the second driving structure 31 can drive the first locking piece 32 to move in a direction close to or away from the first locking structure 23, so that the first locking piece 32 switches between the locking position and the disengaged position.

[0035] In this embodiment, the first mounting seat 80 is mounted at the rear of the vehicle body 10, and the second driving structure 31 is mounted on the first mounting seat 80.

When the anti-collision buffer body 21 needs to be flipped from the transfer position to the protection position, the second driving structure 31 drives the first locking piece 32 to move in the direction away from the first locking structure 23, so that the first locking piece 32 is in the disengaged position. At this time, the anti-collision buffer body 21 can be flipped to the protection position through the first driving structure 22.

Under the action of the first locking piece 32, the anti-collision buffer body 21 cannot rotate relative to the fixing seat 11. At this time, the first locking piece 32 is in the locking position, which can achieve the fixation of the anti-collision buffer body 21. When the anti-collision buffer body 21 needs to be flipped from the transfer position to the protection position, the second driving structure 31 drives the first locking piece 32 to move in the direction away from the first locking plate and disengage from the first through hole and the first limiting hole 231, so that the first locking piece 32 is in the disengaged position.

When the second locking member 42 is in the disengaged position, the second trigger structure 421 senses or contacts one of the two second position sensors 70 located on its side and sends a signal, and when the second locking member 42 is in the locked position, the second trigger structure 421 senses or contacts the other of the two second position sensors 70 located on its side and sends a signal. Through the above arrangement, it is possible to determine whether the second locking member 42 is in the disengaged position and the locked position.

[0063] In one embodiment, the first trigger structure 321 and the second trigger structure 421 are both plate-like structures or sheet-like structures or bolts.

[0064] In one embodiment, the second position sensor 70 is a travel switch. When the second locking member 42 is in the disengaged position, the second trigger structure 421 contacts the second position sensor 70 and sends a signal.

[0065] In one embodiment, the second position sensor 70 is a proximity switch. When the second locking member 42 is in the disengaged position, the second trigger structure 421 senses the second position sensor 70 and sends a signal.

[0066] In one embodiment of the utility model, the sanitation vehicle with an anti-collision buffer structure also includes an alarm device, which is installed on the vehicle body 10. The control system includes a control panel and a controller. The alarm device, the first drive structure 22, the second drive structure 31 and the third drive structure 41 are all communicatively connected to the controller. The alarm device, the first drive structure 22, the second drive structure 31 and the third drive structure 41 can be controlled through the control panel. The controller sends corresponding instructions to the alarm device, the first drive structure 22, the second drive structure 31 and the third drive structure 41 by receiving signals from the first position sensor 50 and the second position sensor 70 to prevent misoperation from damaging related structures.

[0067] When the first locking member 32 is in the locking position, the first trigger structure 321 senses or contacts the first position sensor 50 and sends a signal. When the second locking member 42 is in the locking position, the second trigger structure 421 senses or contacts the second position sensor 70 and sends a signal. When the anti-collision buffer body 21 is in the transfer position and the first locking member 32 is in the disengaged position, the alarm device sounds an alarm. The staff controls the second drive structure 31 through the control system so that the second drive structure 31 drives the first locking member 32 to move toward the first locking structure 23, so that the first locking member 32 is in the locking position, thereby fixing the anti-collision buffer body 21. At this time, the first trigger structure 321 senses or contacts the first position sensor 50 and sends a signal. After receiving the signal, the control system controls the alarm device to stop the alarm. When the anti-collision buffer body 21 is in the protective position and the second locking piece 42 is in the disengaged position, the alarm device sounds an alarm, and the staff controls the third driving structure 41 through the control system so that the third driving structure 41 drives the second locking piece 42 to move toward the second locking structure 24, so that the second locking piece 42 is in the locked position, thereby fixing the anti-collision buffer body 21. At this time, the second trigger structure 421 senses or contacts the second position sensor 70 and sends a signal. After receiving the signal, the control system controls the alarm device to stop the alarm.

[0068] In one embodiment, the alarm device is an audible and visual alarm, which is installed in the cab of a sanitation vehicle with an anti-collision buffer structure.

[0069] In one embodiment, the second drive structure 31 and the third drive structure 41 are both oil cylinders, and the two are in series structure, that is, they extend or retract synchronously. Due to the synchronous movement of the second drive structure 31 and the third drive structure 41, it can be ensured that the first locking member 32 and the second locking member 42 can be extended or retracted synchronously, avoiding interference between the first locking member 32 and the first locking structure 23 and interference between the second locking member 42 and the second locking structure 24 when the anti-collision buffer body 21 is flipped from the transfer position to the protection position or from the protection position to the transfer position.

[0070] It should be noted that the sanitation vehicle with an anti-collision buffer structure also includes related lines, oil valves and oil pipes, etc., which provide auxiliary functions such as power and control for the anti-collision buffer structure 20.

[0071] The sanitation vehicle with an anti-collision buffer structure of the present application has the following advantages:

[0072] 1) Road cleaning operations can be performed on ordinary roads, especially expressways. The anti-collision buffer structure 20 can play a buffering role when rear-ending a social vehicle, reduce the destructive force of the rear-end collision, and protect the personal and property safety of the operating vehicle and social vehicles.

[0073] 2) By selecting anti-collision buffer structures 20 of different specifications, vehicles with different speed differences can be buffered and protected to adapt to different roads and working conditions.

[0074] 3) The setting of control system and alarm device makes human-machine function more friendly and reduces various risks and losses caused by misoperation.
