Description

Technical Field

[0001] This invention relates to the field of sanitation equipment technology and provides a sanitation vehicle with a detachable hatch. Background Technology

[0002] Sanitation truck compartments typically serve as containers for storing garbage. Due to the diverse types of garbage they hold, internal maintenance may be required at any time during prolonged use. Conventional sanitation truck compartments only have one entrance / exit on the rear tailgate. However, the tailgate, primarily used for dumping garbage, is relatively large and its opening largely relies on the vehicle's hydraulic control system. When a malfunction occurs and maintenance is needed, opening the tailgate is difficult. Furthermore, opening the tailgate causes garbage and wastewater to spill out simultaneously, making operation challenging during temporary malfunctions. Therefore, an additional maintenance access point is needed. Generally, the front of the sanitation truck compartment is easily accessible to maintenance personnel due to its location on the truck base, making it a suitable location for the maintenance access point. However, conventional maintenance access doors are typically hinged, requiring a flip-open mechanism. In normal sanitation vehicles, the distance between the front of the compartment and the cab is small, resulting in insufficient longitudinal space for the flip-open access door. Additionally, conventional doors have poor sealing, allowing wastewater and odors to easily escape from the door, causing pollution. Summary of the Invention

[0003] Therefore, the present invention provides a sanitation vehicle with a detachable door, which is equipped with a detachable door panel to meet the opening requirements of the narrow front space of the sanitation vehicle. The door panel is sealed by a double sealing method of embedding a sealing ring in the installation port and pressing the sealing ring on the end plate.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a sanitation vehicle with a detachable hatch, comprising:

[0008] Furthermore, the hatch panel is provided with at least one hatch lock, the hatch lock includes a rotating locking shaft that is rotatably configured, and an operating handle and a locking tongue are respectively fixedly configured at both ends of the rotating locking shaft. The operating handle is located on the side of the hatch panel away from the car body, the locking tongue is located inside the car body, and the front end plate is provided with a locking tongue stop block adapted to the locking tongue on the side inside the car body.

[0009] Furthermore, the locking tongue stop includes a locking tongue abutment plate and a stop mounting plate that are fixedly connected. The stop mounting plate includes a stop adjustment hole. The stop mounting plate is detachably and fixedly connected to the front end plate after passing through the stop adjustment hole with an adjusting bolt. The locking tongue can be engaged with the locking tongue abutment plate by rotation.

[0010] Furthermore, the locking tongue abutment plate is provided with an elastic locking pad on the side facing the locking tongue. The elastic locking pad is provided with a locking transition slope that gradually decreases in thickness from the middle to the upper and lower sides. A locking groove is provided in the middle of the elastic locking pad. A locking positioning strip that matches the locking groove is provided on the side of the locking tongue abutment plate facing the locking tongue.

[0011] Furthermore, there are two latch blocks and two hatch locks. The two latch blocks are respectively located on the left and right sides of the hatch mounting opening.

[0038] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] Example, see attached document Figure 1 ~Appendix Figure 3 The present invention provides a sanitation vehicle with a detachable hatch, including a vehicle body 100 and a detachable hatch assembly 400.

[0040] Specifically, the front end of the carriage body 100 is provided with a front end plate 200, the rear end of the carriage body 100 is provided with a tailgate assembly 300, and a hydraulic cylinder fulcrum assembly 500 is provided on the side of the front end plate 200 facing away from the carriage body 100. This part of the structure is consistent with that of a conventional sanitation vehicle, and will not be described in detail here. See attached... Figure 5 Appendix Figure 6 As shown, the front end plate 200 is provided with a hatch mounting opening 210. A detachable hatch assembly 400 is installed at the hatch mounting opening 210. A mounting opening embedding sealing ring 230 is provided around the side of the opening of the hatch mounting opening 210. An end plate pressing sealing ring 220 is fixedly provided around the outer side of the front end plate 200, as shown in the attached figure. Figure 8 Appendix Figure 9 As shown, the detachable hatch assembly 400 includes a hatch panel with an observation window 440 for observing the interior of the carriage body 100, typically made of tempered glass. The hatch panel and the front end panel 200 are detachably fixedly connected by at least four door panel locking bolts 420. An end plate pressing sealing ring 220 is sealed and fitted to the hatch panel. A door panel sealing ring 430, adapted to the mounting opening embedded sealing ring 230, is fixedly provided on the side of the hatch panel facing the front end panel 200. The sealing fit between the door panel sealing ring 430 and the mounting opening embedded sealing ring 230 is as shown in the attached figure. Figure 4 In the specific structure between the door panel sealing ring 430 and the mounting port embedded sealing ring 230, the mounting port embedded sealing ring 230 has an "L"-shaped bottom sealing surface 231 and a side sealing surface 232 on the side facing the door panel. The side sealing surface 232 has a stepped structure. The door panel sealing ring 430 has a top sealing surface 431 that seals against the bottom sealing surface 231. A stepped door panel side sealing surface 432 is provided on the side of the installation port side sealing surface 232, which is adapted to the installation port side sealing surface 232. The door panel side sealing surface 432 and the installation port side sealing surface 232 are sealed and fitted together. When the hatch panel and the hatch installation port 210 are installed in place, the stepped installation port side sealing surface 232 and the door panel side sealing surface 432 can be adapted and engaged to provide a multi-stage stepped seal for both, further reducing the leakage of liquid and gas in the compartment.

[0041] In another embodiment, to add a locking function to the hatch panel and to facilitate pre-compression of the hatch panel, at least one hatch lock 410 is provided on the hatch panel. In this embodiment, two hatch locks 410 are preferred, and the two hatch locks 410 are respectively provided on the left and right sides of the hatch panel, as shown in the attached figure. Figure 10As shown, the hatch lock 410 includes a rotating locking shaft with an operating handle 411 and a locking tongue 412 fixedly mounted at both ends. The end of the operating handle 411 is equipped with a telescopic extension rod 414, which increases the operating length of the operating handle 411, making the operation of the hatch lock 410 easier. The operating handle 411 is located on the side of the hatch panel away from the car body 100, i.e., on the outside of the car body 100. The locking tongue 412 is located inside the car body 100. The front plate 200, located inside the car body 100, has a locking tongue stop 240 adapted to the locking tongue 412. Two locking tongue stops 240 are provided, one for each hatch lock 410, and are respectively located on the left and right sides of the hatch mounting opening 210. Figure 7As shown, the latch stop 240 includes a latch abutment plate 242 and a stop mounting plate 241 fixedly connected. The stop mounting plate 241 includes a stop adjustment slot 246. In this embodiment, two stop adjustment slots 246 are preferred. The two stop adjustment slots 246 make the installation of the stop mounting plate 241 more stable. The stop mounting plate 241 is detachably and fixedly connected to the front end plate 200 after passing through the stop adjustment slots 246 with adjusting bolts 247. The stop adjustment slots 246 make the distance between the latch abutment plate 242 and the door plate adjustable. When the mounting opening is inserted... When the sealing ring 230, end plate pressing sealing ring 220, and door panel sealing ring 430 age and deform after prolonged use, their thickness will decrease. In this case, shortening the distance between the latch abutment plate 242 and the door panel is necessary to maintain a similar sealing effect as before. The locking latch 412 can be engaged with the latch abutment plate 242 by rotation. An elastic locking pad 243 is provided on the side of the latch abutment plate 242 facing the locking latch 412. The elastic locking pad 243 has a locking transition slope 244 whose thickness gradually decreases from the center upwards and downwards. A locking groove 245 is provided in the middle of the pad 243. A locking positioning strip 413, which matches the locking groove 245, is provided on the side of the locking tongue 412 facing the locking tongue abutment plate 242. During the installation of the hatch panel, in order to achieve a better sealing effect, pressure needs to be applied to the hatch panel so that the hatch panel can better press the sealing ring 220 against the end plate and the sealing ring 230 embedded in the installation port for a tight seal. Applying pressure cannot be effectively controlled manually, so the locking process between the locking tongue 412 and the locking tongue stop 240 completes the process. After the hatch panel is pre-installed, the locking bolt 412 is rotated by operating the lock handle 411 to pass over the elastic locking pad 243. During this process, the locking positioning strip 413 passes through the locking transition ramp 244, which extends from the middle to the upper and lower sides with gradually decreasing thickness. As the locking positioning strip 413 moves, the locking force between the hatch panel and the front end plate 200 increases. At the same time, the pressing force between the hatch panel and the mounting opening embedded sealing ring 230 and the end plate pressing sealing ring 220 also increases. This improves the sealing effect of the hatch panel until it reaches the desired position. Figure 11 Appendix Figure 12 As shown, when the locking positioning strip 413 is inserted into the locking slot 245, the locking is complete.
