Description

Garbage transfer truck

Technical Field

The utility model relates to a garbage transfer vehicle, in particular to a garbage truck with a detachable carriage. More particularly, the present invention relates to a refuse transfer vehicle with a cleaning device.

Background

A refuse transfer vehicle, in particular a wagon-removable refuse vehicle, is a special vehicle used by the municipal environmental sanitation sector to transfer refuse from refuse collection or refuse transfer stations or interruptions in the form of refuse transfer boxes or receptacles of substantially size or specification standard to refuse disposal terminals, such as incineration plants or landfill plants. Of these, hook arm refuse transfer vehicles are the most common, which employ pivotable hook arm assemblies capable of engaging and transporting different refuse transfer boxes of different refuse transfer stations to a refuse disposal terminal for subsequent dumping and disposal of refuse.

The garbage truck with the detachable carriage generally comprises a truck head and a truck body, and the hook arm assembly is arranged on the truck body. When not in use, the hook arm assembly is in a non-operative position overlying the vehicle body. In use, the hook arm assembly is pivoted in a first direction relative to the vehicle body such that an engagement portion on the hook arm assembly engages a corresponding engagement portion on a waste transfer bin which is transferred to the vehicle body of a wagon removable from the vehicle, for example to a waste disposal station, by pivoting the hook arm assembly in a second, opposite direction. The hook arm assembly is then pivoted in the first direction to tilt the waste bin for waste dumping operations. At this point the above steps are repeated and the emptied waste transport bin is transported back to the same or a different waste transport station.

In this way, the carriage-detachable garbage truck can handle the garbage transporting boxes from different garbage transporting stations, which may be loaded with different kinds of garbage, and the garbage overflowed, shaken out or stuck to the outside of the garbage transporting boxes inevitably contaminates the carriage-detachable garbage truck during the handling of the garbage transporting boxes filled with garbage or emptied of garbage and during the unloading (self-unloading) of the garbage.

The garbage truck with the detachable polluted carriage can cause discomfort for operators and people on roads where vehicles pass, cause environmental pollution, influence urban image and even spread diseases.

It is desirable to solve the above technical problems.

Drawings

All aspects of the present application will become more fully understood from the detailed description to follow, taken in conjunction with the accompanying drawings. In the drawings:

FIG. 1 is a simplified schematic block diagram of a refuse transfer vehicle illustrating the principles of the present invention; and

figure 2 is a portion of the structure of a refuse transfer vehicle constructed in accordance with the principles of the present invention showing some of the components of the cleaning apparatus of the refuse transfer vehicle.

Detailed Description

The principles of the present invention are described below with reference to fig. 1 and 2, where fig. 1 is a schematic, simplified block diagram of the principles of the present application, and fig. 2 is a detailed structural section of a refuse transfer vehicle, particularly a car-detachable refuse cart, constructed in accordance with the principles of the present invention. The same numbers in fig. 1 and 2 indicate parts or components that are identical or similar in structure or function.

As shown, the cart of the present invention will be described as an example of a wagon-removable garbage truck, which includes a truck head 12 and a truck body 14 connected to the truck head 12, for example, the truck body 14 may be welded to the truck head 12. Alternatively, the present application is also applicable to the case where the vehicle head 12 and the vehicle body 14 are detachably connected. The vehicle body 14 may be in the form of a frame consisting of longitudinal beams extending in the longitudinal direction of the vehicle body 14 and transverse beams extending in the width direction transverse, e.g. perpendicular, to the longitudinal direction, and optionally oblique beams extending obliquely with respect to the longitudinal and transverse beams. In the description of the present application, the terms "lengthwise direction" and "widthwise direction" relating to the direction/orientation are both for the vehicle body 14 in the drawings, referring to the lengthwise direction and the widthwise direction of the vehicle body 14, respectively. The length direction includes a forward direction and an opposite rearward direction, where "forward" or "front" refers to a direction from the vehicle body 14 toward the vehicle head 12 in the length direction; "rearward" or "rear" is the opposite direction as "forward" or "front". Thus, the vehicle head 12 is positioned forward of the vehicle body 14, and the waste transport vehicle is configured to engage a waste transfer bin or waste collection bin positioned behind the waste transport vehicle.

Mounted on the body 14 is a hydraulic cylinder assembly 20 and a generally L-shaped hook arm assembly 30. Hydraulic cylinder assembly 20 includes a hydraulic cylinder 22 and a hydraulic rod 24 that is extendable and retractable within hydraulic cylinder 22. A first end of the hydraulic cylinder assembly 20 (specifically of the hydraulic cylinder 22) is hinged to the vehicle body 14 such that the hydraulic cylinder 22 of the hydraulic cylinder assembly 20, and thus the entire hydraulic cylinder assembly 20, is pivotable relative to the vehicle body 14 about a first axis X1 extending in the width direction, and an opposite second end of the hydraulic cylinder assembly 20 (specifically of the hydraulic rod 24) is hinged to a portion of the hook arm assembly 30 such that the hydraulic rod 24 of the hydraulic cylinder assembly 20, and thus the entire hydraulic cylinder assembly 20, is pivotable relative to the hook arm assembly 30 about a second axis X2 extending in the width direction. Further, the hook arm assembly 30 is also hinged to the vehicle body 14 such that the hook arm assembly 30 is pivotable relative to the vehicle body 14 about a third axis X3 extending in the width direction.

Thus, when the hydraulic cylinder assembly 20 is actuated to extend the hydraulic rod 24 outwardly from the hydraulic cylinder 22, on the one hand, the hydraulic rod 24 and the hook arm assembly 30 of the hydraulic cylinder assembly 20 pivot relative to each other about the second axis X2, and the hydraulic rod 24 drives the hook arm assembly 30 to pivot relative to the vehicle body 14 about the third axis X3, and on the other hand, the hydraulic cylinder 22 of the hydraulic cylinder assembly 20 pivots relative to the vehicle body 14 about the first axis X1.

In the illustrated embodiment, the hook arm assembly 30 includes a trailing arm 32 and a cross arm 34 connected to one another to form a generally L-shaped structure. The trailing arm 32 extends in a vertical plane defined by the length direction and the vertical direction, the first end 32a of the trailing arm 32 is hinged to the vehicle body 14 as described above, and the hydraulic lever 24 of the hydraulic cylinder assembly 20 is hinged to an intermediate position P of the trailing arm 32 to push or pull the hook arm assembly 30 to pivot about the third axis X3. The crossbar 34 is connected to a second end 32b of the trailing arm 32 opposite the first end 32a and extends transverse, e.g., perpendicular, to the trailing arm 32. The free end of the transverse arm 34 opposite the end connected to the longitudinal arm 32 includes an engagement portion 36 for engaging a waste bin for engaging a corresponding engagement portion of a waste bin to pull the waste bin up or disengage the waste bin after unloading. By way of example, in the illustrated embodiment, the engagement portion 36 of the crossbar 34 may be a hook or slot-like engagement portion.

The trailing arm 32, the cross arm 34 and the engaging portion 36 of the hook arm assembly 30 may all be integrally formed in one piece. Alternatively, any of the trailing arm 32, the cross arm 34, and the joint 36 may be in the form of separate components, or each of the three may be separately formed and fixedly attached together.

The hook arm assembly 30 of the waste transport vehicle can have an inoperative position and an operative position. The block diagram of fig. 2 illustrates the hook arm assembly 30 in a rest position, in which the trailing arm 32 of the hook arm assembly 30 is in a generally horizontal position, at a minimum angle to the vehicle body 14, e.g., at least partially overlying the vehicle body 14. The schematic block diagram of fig. 1 shows the hook arm assembly 30 in an operative position pushed away from the vehicle body 14 by the hydraulic lever 24 of the hydraulic cylinder assembly 20, when the entire hook arm assembly 30 has been pivoted clockwise relative to the vehicle body 14.

The waste transport vehicle constructed in accordance with the present invention further includes a cleaning device 40 disposed on the vehicle body 14. The cleaning device 40 is configured to remove contaminants or waste present on the vehicle body by spraying a liquid onto a portion or portions of the vehicle body 14 after each operation of the waste transport bin, or after multiple operations of the waste transport bin. The liquid sprayed by the washing device 40, also referred to herein as a washing liquid, may be water, or any other cleaning liquid to which an agent with deodorizing and/or disinfecting or sterilizing functions has been added.

The cleaning device 40 generally includes a liquid reservoir 42, such as a tank or other container of deodorizing or sanitizing liquid; a pump 44; and a liquid distribution conduit 46. Liquid is drawn from the liquid reservoir 42 and pumped into the liquid distribution conduit 46 when the pump 44 is operated, and then ejected to a target site on the refuse transfer vehicle via the ejection ports of the distribution conduit 46.

It is envisaged that the dispensing conduit 46 may be in the form of a flexible hose which is coiled or coiled together when not in use and unwound as required when in use, for example as may be provided by a hose reel as is common in the art. Alternatively, the distribution pipe 46 may be provided as a pipe structure of variable length. In some embodiments, the distribution conduit 46 may be in the form of a flexible soft or rigid tube that can be removably attached or telescoped in the field to change the overall length.

It is contemplated that pump 44 may have any known pump configuration within the art, such as any known gear pump, vane pump, plunger pump, etc. hydraulic pump. The pump 44 may be a manual pump or, as shown, may be an electric pump configuration driven by a motor 48. The pump 44 may be a fixed displacement pump or may be a variable displacement pump, for example, to adjust the rate of liquid ejection as needed at any time.

In the schematic block diagram of fig. 1, the liquid reservoir 42 of the washing device 40 is shown supported at a substantially middle position in the longitudinal direction of the vehicle body 14. In this case, the liquid reservoir 42 is disposed so that it is not higher than a support surface of the vehicle body 14 for supporting the trash transfer box, such as a flat upper surface. In this way, the liquid reservoir 42 in the form of a box does not interfere with supporting refuse transfer boxes being pulled onto the body 14 of the refuse transfer vehicle by the hook arm assembly 30.

In the schematic block diagram of fig. 1, an intermediate support member 50 for mounting or supporting other constituent components of the washing device 40 is also shown, the intermediate support member 50 being shown as being permanently (e.g., welded) or removably (e.g., snapped, bolted, etc.) attached to the vehicle body 14. Alternatively, the intermediate support member 50 may be an intermediate support member that rests on the vehicle body 14 solely by gravity. The intermediate support member 50 may be a box structure, a frame structure formed of one or more beams, a bracket or support structure of any shape, or any other mechanical structure capable of supporting and securing.

As shown, the liquid reservoir 42 of the washing device 40 is mounted to the frame structure of the vehicle body 14, and other components of the washing device 40 (including the pump 44, the liquid distribution conduit 46, the motor 48, a controller 52 to be described below) are mounted to or otherwise supported by the intermediate support member 50.

The intermediate support member 50 is disposed on the vehicle body 14 between the vehicle head 12 and the hook arm assembly 30 in the rest position, and the intermediate support member 50 extends upwardly from the vehicle body 14 so that an operator can conveniently operate components such as the liquid distribution conduit 46 and the controller 52.

As shown in fig. 1, the liquid reservoir 42 of the washing device 40 is not on the intermediate support member 50, but is located behind the intermediate support member 50, for example, at a middle position of the vehicle body 14 in a length direction thereof, but it is not necessary as will be readily understood by those skilled in the art. For example, in the case where the installation space on the intermediate support member 50 is sufficient (e.g., the internal space of the box structure or the frame structure is sufficiently large), the liquid reservoir 42 may also be installed at the intermediate support member 50. In some embodiments, liquid reservoirs 42 may be mounted on either side of intermediate support member 50 in the width direction of body 14. In summary, the mounting locations of the various components of the cleaning device 40 are not limited by the schematic of FIG. 1, and FIG. 1 is merely an exemplary arrangement of the various components of the cleaning device 40.

Also shown in fig. 1 are the connecting lines between the liquid reservoir 42 and the pump 44, as well as the connecting line L1 (shown in solid lines) between the pump 44 and the liquid dispensing tube 46, and a control line L2 (shown in dashed lines) between the controller 52 and the motor 48, described below.

As mentioned above, the washing device 40 may also include a controller 52 for controlling the start and stop of the pump 44 or motor 48 and/or their operating parameters. The controller 52 controls the operating parameters of the motor 48 to control the spray parameters of the liquid sprayed from the liquid distribution conduit 46. In one embodiment, the operating parameters of the pump 44 include, for example, at least one of a mode of operation of the pump (e.g., continuous or intermittent operation), a length of operation of the pump, a pump speed, etc., to control injection parameters for injecting liquid from the liquid distribution conduit 46, which may include, but are not limited to: the injection rate or the change curve of the injection rate with time, the injection mode (continuous injection or intermittent injection), the duration of each injection in the intermittent injection mode or the time interval between two adjacent injections, and the like.

Still further, the controller 52 of the washing device 40 may include an activation button configured as a self-resetting button, making the operation of the washing device 40 safer and more reliable, and easier to service.

In one embodiment, the controller 52 of the washing device 40 may employ time relay control in order to efficiently and accurately control the operation time of the motor 48 and thus the pump 44. This can effectively prevent the occurrence of a forgetting to turn off.

In one embodiment, the controller 52 of the washing device 40 may include an emergency stop button so that the emergency stop button may be pressed directly to shut off the electrical system and stop the washing operation in time to prevent danger in case of an emergency or when it is necessary to immediately shut down the operation of the washing device 40.

In one embodiment, the controller 52 of the washing device 40 may include an indicator light for indicating the status of the motor 48 or pump 44 as allowed, for example, a light on may indicate that the motor 48 or pump 44 is in an operational state to alert an operator or other personnel, and a light off may indicate that the motor 48 or pump 44 is not in an operational state in which the operator may perform service and troubleshooting. Of course, it will be appreciated by those skilled in the art that the indicator lights may indicate different operating states of the motor 48 or pump 44 by emitting different colored lights or by flashing or not.

In one embodiment, the controller 52 of the cleaning device 40 may adopt a control loop and main loop dual-risk design, which effectively ensures the safe operation of the electrical system.

As described above, the garbage transfer vehicle including the cleaning device 40 can clean and/or sterilize/disinfect the vehicle body as needed, not only improving the comfort of the operator, but also reducing environmental pollution and beautifying the urban environment. The washing device 40 is provided on the vehicle body 14 and supported by the vehicle body. Herein, the term "support" includes merely "placement" under its own weight, and also includes "attachment" or "fixation" in any form. Further, the supporting manner and the placing position of each component of the washing device 40 are not limited to the examples shown in the drawings and described above, and any supporting manner and placing position that can achieve the same function and effect are within the scope of the present application.

Although specific embodiments of the present application have been described herein in detail, they have been presented for purposes of illustration only and are not to be construed as limiting the scope of the application. Furthermore, it should be clear to a person skilled in the art that the embodiments described in the present specification can be used in combination with each other. Various substitutions, alterations, and modifications may be conceived without departing from the spirit and scope of the present application.
