Floating balanced compression sewage discharge door of washing and sweeping vehicle and washing and sweeping vehicle

Abstract

This utility model provides a floating, balanced, and clamping sewage gate for a sweeper truck and the sweeper truck itself. It includes a sewage gate body, with a sewage gate fixing frame connected to the outer side of the sewage gate body. A hydraulic cylinder is hinged to the outer side of the sewage gate fixing frame at its middle portion. The other end of the hydraulic cylinder is hinged to the truck body at a first hinge seat. The upper end of the sewage gate fixing frame is hinged to the truck body at a second hinge seat. There are two sets of second hinge seats, symmetrically arranged on the left and right sides of the first hinge seat. This sewage gate design separates the sewage gate fixing frame and the sewage gate body. When the sewage gate fixing frame applies pressure to the sewage gate under the action of the hydraulic cylinder, the sewage gate will be evenly stressed to conform to the truck body it is connected to, thus achieving uniform clamping force and preventing the problem of uneven force and inadequate clamping that occurs with traditional gates.

Description

Technical Field

[0001] The utility model relates to the field of sanitation vehicle production and manufacturing, in particular to a floating balanced compression sewage discharge door of a washing and sweeping vehicle and the washing and sweeping vehicle. Background Art

[0002] The sewage door is a switch door installed on the rear side of the washing and sweeping vehicle. The sealing quality of the sewage door directly affects whether sewage and other debris will leak and whether it will cause secondary pollution to the environment. At present, the sewage door of the washing and sweeping vehicles is basically hinged to the car body at the top, and the middle part of the sewage door is directly connected to the car body through the bearing seat and the telescopic hydraulic cylinder. This connection method has the following disadvantages:

[0003] 1. Uneven compression between the sewage door and the carriage or assembly errors, inaccurate gap adjustment, natural aging of the rubber, etc. will cause the sewage door to not be tightened firmly, causing sewage leakage and bringing secondary pollution to the environment.

[0004] 2. The sewage door is not evenly tightened. If the gap of the top fixed seat is adjusted too large, it will cause the bottom to be suspended and not tightened, or the rubber will be over-compressed, causing the rubber to deform and cause leakage. If the gap is adjusted too small, the bottom will be pressed tightly and the top will be suspended, and it cannot balance the local looseness caused by the natural aging of the rubber.

[0005] 3. The entire sewage door is connected to the hydraulic cylinder through only one hinge point. The sewage door shakes during movement. After long-term use, the sewage door may be deformed or the connection may be damaged. Utility Model Content

[0006] In view of the above problems, the utility model provides a floating balanced compression sewage door of a washing and sweeping vehicle and a washing and sweeping vehicle. The sewage door has a sewage door fixing frame and a sewage door body which are separated. When the sewage door fixing frame applies pressure to the sewage door under the action of the oil cylinder, the sewage door will be uniformly stressed as a whole to fit the vehicle body connected thereto, thereby achieving the purpose of uniformly applying compression force and preventing the problem of uneven force and inadequate compression of traditional doors from occurring.

[0007] A floating balanced compression sewage door of a washing and sweeping vehicle and the washing and sweeping vehicle, comprising a sewage door body, the outer side surface of the sewage door body is connected to a sewage door fixing frame, the outer side surface of the sewage door fixing frame and the middle part thereof are hinged with a hydraulic cylinder, the other end of the hydraulic cylinder is hinged to the car body at a first hinge seat, the upper end of the sewage door fixing frame is hinged to the car body at a second hinge seat, the second hinge seat is divided into two groups, and the two groups of second hinge seats are symmetrically arranged on the left and right sides of the first hinge seat.

[0008] Preferably, a fixing seat slidably connected to the output rod of the hydraulic cylinder is installed on the carriage at the lower end of the sewage discharge door fixing frame.

[0009] Preferably, two groups of hinged rods are symmetrically installed on the outer side surface of the sewage discharge door fixing frame with respect to the hydraulic cylinder, and the other end of each group of hinged rods is hinged to a corresponding group of second hinged seats.

[0010] Preferably, the hinge rod is connected to the middle part of the sewage door fixing frame through a pin shaft.

[0011] Preferably, a gap is provided at the connection between the pin shaft and the sewage door fixing bracket.

[0012] Preferably, the pins are in two pieces, and the two pins are symmetrically distributed on the left and right sides of the hydraulic cylinder.

[0013] Preferably, the output rod of the hydraulic cylinder is also connected to a transverse guide rod, which penetrates the fixing frame outwards and is slidably connected to the fixing frame, and both ends of the transverse guide rod are intermittently engaged with the sewage door body.

[0014] Preferably, a clamping seat cooperating with the transverse guide rod is installed on the sewage door body.

[0015] Preferably, the sewage door fixing frame is a rigid frame formed by welding steel pipes.

[0016] Preferably, the sewage door body and the sewage door fixing frame are welded as one body.

[0017] The utility model also discloses a washing and sweeping vehicle, which comprises the sewage discharge door as described above.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model adopts a structural form in which a hydraulic cylinder is connected to a fixing frame, and the fixing frame is connected to the sewage door, so that the overall force-bearing area of ​​the sewage door is increased, and the force on the joint surface with the carriage is uniform, which can solve the problem of false sealing caused by assembly errors, inaccurate gap adjustment, rubber aging and other problems, reduces the after-sales cost of replacing aging rubber, and has a more compact structure and a more reasonable layout.

[0020] The rubber is a vulnerable part. If the force is uneven, the hard rubber will be deformed and damaged quickly after repeated movement. Under the high pressure in the car, the rubber will crack or age and not rebound. Because of the uneven force, the upper part cannot be pressed, and the lower cylinder is always pressing, which leads to rapid damage. In addition, the loose parts will release air and the damage caused by cavitation will soon fail. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0028] like Figure 1-4As shown, the utility model discloses a floating balanced compression sewage door of a washing and sweeping vehicle. Compared with the traditional sewage door directly installed on the rear side of the car body 1 through a hydraulic cylinder, the utility model first installs two second hinged seats 3 on the rear side of the car body, each of which is hinged to a hinged rod 5, and the other end of the hinged rod is hinged to the middle part of the sewage door fixing frame 9. The sewage door fixing frame is a rigid frame composed of rectangular steel pipes welded together, and the width is the same as the width of the sewage door body 6, and the height is slightly less than the height of the sewage door body. The sewage door body 6 is welded to the inner side of the sewage door fixing frame 9. A sliding seat is installed in the middle part of the sewage door fixing frame, and a long slot hole along the movement direction of the hydraulic rod is opened on the side of the sliding seat, and the hydraulic rod can be slidably connected with the long slot hole of the sliding seat. The end of the output rod of the hydraulic cylinder 4 extends to the inside of the fixing seat 8 installed on the outer side of the car body at the lower end of the sewage door. The hinged rod 5 is symmetrically installed on the left and right sides of the hydraulic cylinder 4. The upper end of the hydraulic cylinder 4 is installed between two second hinged seats 3 on the outer side of the vehicle compartment through the first hinged seat 2.

[0029] Two sets of pin seats are installed in the middle part of the sewage door fixing frame 9 along the up and down direction. The two sets of pin seats are symmetrically arranged on the left and right sides of the hydraulic cylinder along the left and right directions. Each set of hinge seats is connected to a hinge rod 5 through a pin 7.

[0030] A clamping seat 11 is symmetrically installed on the sewage door body 6 and on the left and right sides of the hydraulic cylinder 4. The clamping seat is an open-type bayonet with the opening facing downward. A transverse guide rod 10 is connected to the piston rod of the hydraulic cylinder. The transverse guide rod 10 penetrates the fixed seat 8 to the left and right, and can slide up and down in the long slot hole of the fixed seat together with the piston rod when the piston rod moves. After sliding until it is clamped into the clamping seat 11, it can play a role of auxiliary support and guidance for the movement of the sewage door body 6, thereby preventing the sewage door body from shaking during movement.

[0031] When the hydraulic cylinder 4 is actuated to drive the sewage door fixing frame 9 to rotate around the second hinge seat 3, the sewage door fixing frame applies force to the outer side surface of the sewage door body as a whole, thereby pressing the sewage door body against the outer side surface of the car as a whole. The pressing force around the sewage door is balanced, and the contact surface with the car body is also balanced in force and the gap is consistent, which can play an effective sealing role.

[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
