The following structures are respectively arranged on the left side and the right side of a door frame of a rear door of a waste compacting tank body, i.e., a hydraulic oil cylinder is arranged on the door frame of the rear door of the tank body; the upper end of the hydraulic oil cylinder is hinged at the upper end of the door frame through a telescopic end of the oil cylinder; the lower end of the hydraulic oil cylinder is connected onto a first locking hook; the hydraulic oil cylinder is connected with a connecting rod by a hinge of a fixing end of the oil cylinder; two ends of the connecting rod are respectively connected with an upper locking hook and a lower locking hook; the upper locking hook and the lower locking hook are respectively fixed by an upper locking hook rotating shaft and a lower locking hook rotating shaft; an upper limiting stop block and a lower limiting stop block are arranged on the door frame; and the rear door of the tank body is connected with the door frame by a door hinge. According to the double-point locking device, the compacting tank rear door of the waste compacting truck can be opened and tightly closed and locked to prevent the leakage, so that the effect of avoiding secondary pollution is achieved. The double-point locking device has the advantages of simple structure, convenience for operation and high automatic degree.
Description
Technical field
The utility model relates to a kind of device of garbage compression vehicle compression box, particularly a kind of garbage compression vehicle compression box back door hydraulic pressure two point latching device.
Background technology
Transporting after front domestic waste transportation is taked to compress decrement mostly, and guarantee the airtight sewage of not revealing in garbage compression vehicle compression processing and transportation, is the gordian technique of garbage compression vehicle.And mostly adopt in the past mechanical, hand-driven or hydraulic pressure single head latching device to realize, so not only bad sealing but also inconvenient operation, easily caused sewage leakage in case, forms secondary pollution.
Summary of the invention
In order to overcome the problem of existing mechanical, hand-driven or hydraulic pressure single head latching device bad sealing, inconvenient operation, the utility model provides a kind of compression garbage truck compression box back door hydraulic pressure two point latching device.
the utility model solves the technical matters that prior art exists, the technical scheme that adopts is: a kind of garbage compression vehicle compression box back door two point latching device, comprise: hydraulic ram, oil cylinder fixed end hinge, the upper limit block, connecting rod, upper latch hook rotating shaft, upper latch hook, the lower limit block, upper locking pin, lower locking pin, lower latch hook, lower latch hook rotating shaft, oil cylinder telescopic end hinge, door hinge, it is characterized in that: there is respectively following mechanism the doorframe left and right sides at garbage-compressing casing back door: a hydraulic ram is housed on the doorframe of case rear door, the upper end of hydraulic ram is by the upper end of oil cylinder telescopic end chain connection at doorframe, the lower end of hydraulic ram is connected on the first latch hook, hydraulic ram is connected with connecting rod by oil cylinder fixed end hinge, and the two ends of connecting rod are connected with lower latch hook with upper latch hook respectively, upper latch hook and lower latch hook are fixed by upper latch hook rotating shaft and lower latch hook rotating shaft respectively, upper limit block and lower limit block are arranged on doorframe, case rear door connects by door hinge with doorframe.
The beneficial effects of the utility model are, compression garbage truck compression box back door can be opened and tight sealing locking, prevent from revealing, and to reach the effect of stopping secondary pollution, this apparatus structure is simple, easy to operate, and degree of automation is high.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Shown in figure: case rear door 1, hydraulic ram 2, compression casing 3, oil cylinder fixed end hinge 4, upper limit block 5, connecting rod 6, upper latch hook rotating shaft 7, upper latch hook 8, lower limit block 9, upper locking pin 10, lower locking pin 11, lower latch hook 12, lower latch hook rotating shaft 13, oil cylinder telescopic end hinge 14, door hinge 15, doorframe 16.
Below in conjunction with embodiment and accompanying drawing, the utility model is described further.
The specific embodiment
A hydraulic ram is equipped with respectively in the left and right sides at the doorframe 16 of case rear door, as shown in Figure 1, be the hydraulic ram 2 in left side, the upper end of this hydraulic ram 2 is connected to the upper end of doorframe 16 by oil cylinder telescopic end hinge 14, and the lower end of hydraulic ram 2 is connected on the first latch hook 8; Hydraulic ram 2 is connected with connecting rod 6 by oil cylinder fixed end hinge 4, and the two ends of connecting rod 6 are connected with upper latch hook 8, lower latch hook 12 respectively; Upper latch hook 8 and lower latch hook 12 are fixing by upper latch hook rotating shaft 7 and lower latch hook rotating shaft 13 respectively; Upper limit block 5 and lower limit block 9 are arranged on doorframe 16; Case rear door 1 is connected with doorframe by door hinge 15 connections.
The structure on the right side of the doorframe 16 of case rear door is identical with the left side.
In Fig. 1, as seen this device left side is locking state, and at this moment, two point locking takes latch hook 8 and lower latch hook 12 by on locking pin 10 and lower locking pin 11 on the inboard special arcuate structure locking what of latch hook.Hydraulic ram 2 telescopic ends are connected with the hinge through part oil cylinder telescopic end hinge 14 that is fixed in case rear door 1, the other end is connected with hydraulic ram fixed end hinge 4, upper latch hook 8 again with connecting rod 6 upper end hinges, the connecting rod lower end is connected with lower latch hook 12, start working when stretching out when hydraulic ram 2 like this, at first hydraulic ram moves downwards, depress simultaneously latch hook 8, latch hook rotates around lock hook shaft, the latch hook head begins to leave locking pin 10 and does by the connecting rod 6 lower latch hooks 12 of drive and move equally with top hook, unclamps locking.On this moment, latch hook 8 and lower latch hook 12 are blocked by upper limit block 5 and lower limit block 9, and hydraulic ram 2 continues to stretch out, and promote oil cylinder telescopic end and oil cylinder telescopic end hinge 14, drive case rear door 1 and open the back door around door hinge 15.Close door and locking action contrary to the above.
This device right side and left side structure, locking state are identical, keep strokes.
