Description

Technical Field:

[0001] The utility model relates to the technical field of the maintenance of sanitation vehicles and equipment, and more specifically to a maintenance room for the maintenance of sanitation vehicles. Background Art:

[0002] Existing road sweepers, sprinklers, etc. are all sanitation vehicles, which often run in the city to improve the sanitation and cleanliness of the city;

[0003] Due to functional requirements, sanitation vehicles are very heavy. When they need to change the engine oil or conduct simple inspections on the bottom and replace some small parts, conventional lift operations are generally used. Because of their large tonnage, the supporting lifts generally use four-column lifts, and their maximum load-bearing capacity also needs to meet the requirements. The purchase and manufacturing costs are very high. Therefore, in general maintenance sites, large-tonnage lifts are generally few in number. With a small number, sanitation vehicles need to queue for maintenance. For some sanitation vehicles that only require routine maintenance, generally, only the engine oil in the chassis needs to be drained, new engine oil is filled, and a simple inspection of the chassis is carried out. In fact, the time required for maintenance is very short. Instead, the time taken for lifting and lowering on the lift occupies too much time, which is not convenient and instead occupies the usage time of large-tonnage lifts. Summary of the Utility Model:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a maintenance room for the maintenance of sanitation vehicles. It can be used for sanitation vehicles that require routine maintenance to change engine oil and conduct simple inspections on the bottom. It can be operated without lifting the sanitation vehicle, with convenient and simple operation, high efficiency, and does not occupy too much of the large-tonnage lift. The large-tonnage lift can be used for sanitation vehicles that require major repairs or other operations, and it has good use effects.

[0024] In an embodiment, as shown in Figures 1 to 6 a maintenance room for a sanitation vehicle inspection, which includes a groove formed on the ground and extending downward and longitudinally, and this groove is the main body 10 of the maintenance room;

[0025] One side wall at the rear of the main body 10 of the maintenance room is formed with a staircase 11 extending towards the opposite side wall; this staircase 11 facilitates people to enter and exit the main body 10 of the maintenance room.

[0026] Both middle parts of the left and right inner side walls of the main body 10 of the maintenance room are fixedly provided with longitudinally extending moving mechanisms 20, and the left and right ends of the support frame 30 are mounted on the moving blocks 21 of the two moving mechanisms 20;

[0027] The middle part of the support frame 30 is formed with a middle through hole 31, and the material receiving bucket 100 is inserted into the middle through hole 31. A radially extending edge 101 is formed on the outer side wall of the top of the material receiving bucket 100, and the bottom surface of the radially extending edge 101 is pressed against the top surface of the middle part of the support frame 30; convex portions are formed on the top surfaces of the left and right parts of the radially extending edge 101, and the two ends of the hand-held part are movably connected to the two convex portions.

[0028] The material receiving bucket 100 corresponds to the engine oil outlet of the chassis of the sanitation vehicle.

[0029] Furthermore, connecting plates 40 are fixedly provided at the front and rear parts of the ground on the left and right sides of the main body 10 of the maintenance room, adjusting plates 41 are mounted on the top surfaces of the connecting plates 40, the adjusting plates 41 at the left part and the right part at the front are respectively fixedly provided with a first infrared emitter 1 and a first infrared receiver 2, and the first infrared emitter 1 irradiates infrared rays to the receiving end of the first infrared receiver 2;

[0030] The adjusting plates 41 at the left part and the right part at the rear are respectively fixedly provided with a second infrared emitter 3 and a second infrared receiver 4, and the second infrared emitter 3 irradiates infrared rays to the receiving end of the second infrared receiver 4.

[0031] Furthermore, end plates 42 are fixed to both the front and rear of the top surface of the connecting plate 40. The adjusting screw 43 is movably connected to the corresponding two end plates 42 through bearings. One end of the adjusting screw 43 extends out of the corresponding end plate 42 and is fixed with a rotating part 44. The adjusting block 45 is screwed onto the corresponding adjusting screw 43. The bottom surface of the adjusting block 45 is fixed with a bottom sliding block 46. The top surface of the side of the bottom sliding block 46 close to the main body 10 of the maintenance room is fixed with an adjusting plate 41.

[0032] A guide groove extending in the front-rear direction is formed on the bottom surface of the bottom sliding block 46. A guide rail extending in the front-rear direction is fixed to the top surface of the connecting plate 40. A guide strip 47 extending in the front-rear direction is formed or fixed on the top surface of the guide rail. The guide strip 47 is inserted into the corresponding guide groove and is matched with the guide groove.

[0033] With this structure, by rotating the rotating part 44, the adjusting block 45 can be moved back and forth, realizing the position movement of the first infrared emitter 1, the first infrared receiver 2, the second infrared emitter 3, and the second infrared receiver 4, so as to ensure that the first infrared emitter 1 and the first infrared receiver 2 correspond to the front wheels of the sanitation vehicle, and ensure that the second infrared emitter 3 and the second infrared receiver 4 correspond to the rear wheels of the sanitation vehicle.

[0034] Furthermore, the moving mechanism 20 includes a middle connecting plate extending in the front-rear direction fixed to the inner side wall on the left or the inner side wall on the right of the main body 10 of the maintenance room. Adjusting fixing plates 22 are fixed to the side walls at the front and rear ends of the middle connecting plate. The two ends of the moving screw 23 extending in the front-rear direction are movably connected to the two adjusting fixing plates 22 through bearings. A moving servo motor 24 is fixed to the outer end surface of one of the adjusting fixing plates 22. The output shaft of the moving servo motor 24 is a spline shaft, which is inserted into the spline hole at one end of the corresponding moving screw 23 and drives the corresponding moving screw 23 to rotate. The moving block 21 is screwed onto the corresponding moving screw 23.

[0035] A wear-resistant self-lubricating plate 211 is fixed to one side wall of the moving block 21, which is closely attached to the side wall of the corresponding middle connecting plate.

[0036] Vertical positioning columns 212 are fixed to both the front and rear of the top surfaces of the two moving blocks 21. Vertical jack holes are formed in the front and rear of the left and right parts of the support frame 30. The vertical positioning columns 212 are inserted into the corresponding vertical jack holes. The top ends of the vertical positioning columns 212 extend out of the top ends of the corresponding vertical jack holes. The bottom surfaces of the left and right parts of the support frame 30 are pressed against the top surfaces of the corresponding moving blocks 21.

[0037] The support frame 30 includes two transverse beams 33 corresponding to the front and back. A middle plate body 32 is provided in the middle between the two transverse beams 33. Side beams are provided on the left and right sides between the two transverse beams 33. The front and back ends of the side beams and the front and back ends of the middle plate body 32 are welded and fixed to the inner side walls of the two transverse beams 33. A middle through hole 31 is formed in the middle of the middle plate body 32;

[0038] Vertical jacks are formed in the middle of the left and right ends of the transverse beam 33.

[0039] All the electrical equipment used in this embodiment is electrically connected to the controller in the control cabinet fixed on the ground outside the main body 10 of the maintenance room through electrical connection lines, and is controlled to operate through the controller. This is a conventional structure and will not be elaborated here.

[0040] When this embodiment is in use, it can operate through two mobile servo motors 24 to make the two mobile blocks 21 move forward and backward separately. It can also press the support frame 30 against the two mobile blocks 21 and make the vertical positioning columns 212 inserted into the corresponding vertical jacks (the inner diameter of the vertical jacks is larger than the outer diameter of the vertical positioning columns 212, generally at least 5 mm larger). By operating the two mobile servo motors 24 simultaneously, the two mobile blocks 21 are moved. For the simultaneous operation of the two mobile servo motors 24, no matter how synchronous they are, there must be a small time difference. This gap can be adjusted by the distance between the inner diameter of the vertical jacks and the outer diameter of the vertical positioning columns 212, so as to ensure that the support frame 30 can move forward and backward with the two mobile blocks 21;

[0041] When in use, drive the sanitation vehicle so that the wheels are on the ground on the left and right sides of the main body 10 of the maintenance room. The front wheels block the infrared rays of the front first infrared emitter 1, so that the receiving end of the first infrared receiver 2 cannot sense the infrared rays. Similarly, the rear wheels block the infrared rays of the rear second infrared emitter 3, so that the receiving end of the second infrared receiver 4 cannot sense the infrared rays, indicating that the driving position of the sanitation vehicle is correct;

[0042] At this time, the stairs 11 are behind the sanitation vehicle. People can enter the main body 10 of the maintenance room from the stairs 11. At the same time, insert the receiving barrel 100 into the central through hole 31. The bottom surface of the radially extending edge 101 of the receiving barrel 100 is pressed against the top surface in the middle of the support frame 30. Then, control the two mobile servo motors 24 to run simultaneously, and the support frame 30 can be moved forward, so that the receiving barrel 100 can be located at the oil discharge port in the middle of the chassis of the sanitation vehicle. After the end cover at the oil discharge port is opened, the oil can be drained into the receiving barrel 100, which is very convenient. At the same time, the structure of the chassis of the sanitation vehicle can also be viewed from bottom to top for simple inspection and simple maintenance, which is very convenient.

[0043] For operations such as maintenance, after the engine oil is drained, the support frame 30 can be moved forward to the front end by controlling the two moving servo motors 24 to run simultaneously, preventing it from affecting manual inspection, which is very convenient.

[0044] After the detection is completed, the sanitation vehicle can drive away. Then, by controlling the two moving servo motors 24 to run simultaneously, the support frame 30 can be moved backward to the rear. Hold the hand-held part to take out the material receiving bucket 100. After walking out of the main body 10 of the maintenance room, it can be dumped, which is very convenient.

[0045] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and can have many variations. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention should be considered to fall within the protection scope of the present invention.
