Abstract
The invention relates to the installation of a backdoor of a dump truck and a door opening method thereof. In the installation method, a hinge is arranged on a lateral plate of a truck body which is adjacent to a lateral upper corner of the backdoor. The hinge is matched with a latch hook which is in related joint with the backdoor of the truck. The latch hook is controlled by a rod link mechanism which is arranged on the hinge. A hook is arranged on a lateral plate of the truck body which is adjacent to a lower corner on the same lateral of the backdoor. A hinge is arranged on a lateral plate of the truck body which is adjacent to an upper corner on the other side of the backdoor. The hinge is provided with a bolt hinge which is connected with the backdoor of the truck. A bolt hinge is arranged between a lower corner on the same side of the backdoor of the truck and the adjacent lateral plate of the truck body. The door opening method is one of the methods of back upward starting and level rotating starting to the lateral plate direction of the truck body. The installation of the backdoor of the dump truck and the door opening method has the advantages that the backdoor of the dump truck can be turned over back upwards or levelly to one side; one backdoor can be used for two purposes; the damage phenomenon of the backdoor can be improved; the adaptability and the service life of the truck carriage are improved.
Description
Technical field:
The present invention relates to a kind of installation and door opening method thereof of self dumping lorory back door jack, belong to the dumping car field of components, be specifically related to the annex of dumping car, the mounting means of this annex and using method are different with conventional truck, can more effectively improve the service life of car body.
Background technology:
The installation method of conventional self dumping lorory back door jack is: the upper left corner and the upper right corner at the back door all adopt solid joint to be connected with car body, there is not attachment point between the bottom of door and car body, so it is a kind of that the unlatching form has only, be exactly to overturn to the back upper place, the drawback of this opening ways is: be used for the bigger block of load volume, lifting can cause the back door seriously to pound damage when tilting, and influences compartment service life, so often need remove the back door, waste time and energy.
Summary of the invention:
The purpose of this invention is to provide a kind of self dumping lorory back door jack that makes and both can overturn to the back upper place, the installation and the door opening method thereof of the self dumping lorory back door jack that can horizontally rotate to a side are accomplished dual-use material again, to improve the applicability and the service life in compartment.
Installation method of the present invention is: with the side at back door on a hinge is installed on the adjacent car body side plate in angle, hinge axis in horizontal direction, latch hook of assembling on hinge, latch hook and car back door overlap joint, latch hook is by a connecting rod mechanism control that is contained on the hinge, handle is equipped with in termination at connecting rod mechanism, and a hook that this inferior horn of back door and car body side plate can be combined is installed on the car body side plate adjacent with the homonymy inferior horn at car back door; With the opposite side at back door on a hinge is installed on the adjacent car body side plate in angle, hinge axis in horizontal direction, latch hinge of assembling on hinge, the hinge axis of latch hinge in vertical direction, the latch hinge is connected with the car back door, at the homonymy inferior horn at car back door and adjacent car body side sheet room a latch hinge is installed, the hinge axis of latch hinge in vertical direction.
By the self dumping lorory back door jack that above-mentioned installation method is installed, its door opening method is: be flipped open and horizontally rotate a kind of in the unlatching to a sidecar envelope side plate direction to the back upper place.
The invention has the beneficial effects as follows:
Self dumping lorory back door jack by installation method of the present invention is installed both can overturn self dumping lorory back door jack to the back upper place, can horizontally rotate to a side again, accomplished dual-use material, can improve back door damage phenomenon, the applicability and the service life of improving the compartment.
Description of drawings:
Fig. 1 is the installation method scheme drawing of self dumping lorory back door jack;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right elevation of Fig. 1;
Fig. 4 is that the A of Fig. 2 is to partial view;
Fig. 5 is that the B of Fig. 1 is to partial view;
Fig. 6 is that the C of Fig. 1 is to partial view.
The specific embodiment:
With reference to accompanying drawing, below with self dumping lorory back door jack can to the back upper place be flipped open and to the right car body side plate direction horizontally rotate that to open be that present invention is described for example:
The installation method of self dumping lorory back door jack is: a hinge 2 is installed on the car body side plate adjacent with the upper left corner at back door 15, hinge axis in horizontal direction, latch hook 6 of assembling on hinge 2, latch hook 6 and car back door 15 overlap joints, latch hook 6 is by connecting rod mechanism 5 controls that are contained on the hinge, in the termination of connecting rod mechanism 5 handle 8 is housed, a hook 7 that 15 lower left corners, back door and car body side plate can be combined is installed on the car body adjacent with 15 lower left corners, car back door; A hinge 13 is installed on the car body side plate adjacent with the upper right corner at back door 15, hinge 13 comprises hinge seat 3, hinge arms 4, hinge axis 16, hinge axis 16 in horizontal direction, latch hinge 1 of assembling on hinge 13, the hinge axis of latch hinge 1 in vertical direction, latch hinge 1 is connected with car back door 15, at 15 lower right corner, car back door and adjacent latch hinge 14 of car body side sheet room installation, latch hinge 14 is made up of bearing pin 9, hinge seat 10, hinge arms 11, and the hinge axis 9 of latch hinge 14 in vertical direction.
The present invention has changed the fixed hinge form in the upper left corner, original back door, be designed to hinge and cooperate latch hook and car back door overlap joint, the car back door is upper right to increase the latch hinge again at former fixed hinge in form, right lower quadrant did not have attachment point originally, was designed to rotating shaft (hinge axis) now, and purpose is to make the opening ways at back door increase a kind of, become the dual-purpose type back door, the opening ways that becomes the self-discharging carriage back door is accomplished dual-use material by overturning to right side upset backward to the back upper place, improves the applicability in compartment.Be particularly useful for the dual-purpose discharging vehicle in general ore deposit, the medium that roping is different satisfies user's different demands.
Self dumping lorory back door jack of the present invention also can be installed as can to the back upper place be flipped open and to the left the car body direction horizontally rotate unlatching, the method for its installation method and above-mentioned embodiment is basic identical, the installation site of left and right sides fabricated section is changed mutually and is got final product.
When the back door needs side to open, open hook 7, and turning handle 8, by the effect of connecting rod mechanism 5 and hinge 2, open latch hook 6, door is opened laterally, the latch hinge 1 that this moment, the back door will be by the upper right corner and the following hinge 13 in the lower right corner for rotating shaft is, go to parallel with the right side compartment board.Wherein, handle 8 is fixed on the screw rod 12 that is installed on the compartment board of envelope left side.
When the back door need upwards be turned over, by turning handle 8, close latch hook 6, open hook 7 again, and the hinge axis of latch hinge is extracted out, the back door will be rotating shaft system with the hinge 2 and 13 on left and right top during lifting, overturn to the back upper place.
