Abstract
The utility model relates to a gate-in-gate structure used for a rear gate of a tipper, and the rear gate is provided with a rear gate frame. The structure is characterized in that the gate-in-gate is connected with the rear gate frame through a hinge to realize the pivoted connection between the gate-in-gate and the rear gate frame; a gate-in-gate lock is mounted on the rear gate to realize the opening and closing of the gate-in-gate; the rear gate is connected with a wagon box through a wagon box hinge; and the opening and closing of the whole rear gate can be automatically realized through the rear gate lock. The structure realizes the additional function of the rear gate of the tripper, so that sacked goods can be transported by the tipper, thereby broadening the transportation range and increasing the transportation benefit of the tipper, and facilitating the use and satisfying the benefit maximization of users.
Description
Technical field
The utility model relates to a kind of construction machinery and equipment dumping car, relates in particular to the Structure for door on door leaf of self dumping lorory back door jack.
Background technology
Dumping car sometimes need to transport bag cargo (for example bagged cement, bagged grain etc.), but the compartment of original structure can not manually remove to load and unload this type of bag cargo when shipping goods.Therefore be necessary to design a kind of back door, transport bag cargo to make things convenient for dumping car, thus but the traffic coverage of expansion dumping car.
Summary of the invention
The utility model is intended to solve above-mentioned the problems of the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme of being taked to be:
A kind of self dumping lorory back door jack Structure for door on door leaf, this back door has back doorframe, it is characterized in that: this door in door is connected with this back doorframe with hinge, and the back doorframe is pivotable is connected with this to realize this door in door; This back door is equipped with the door in door lockset, to realize the opening and closing of this door in door; This back door utilizes compartment hinge and compartment to link together, and the opening and closing at whole back door realize automatically by the back door lockset.
Preferably, the last plane of student's frame of this door in door and cabin floor are on a horizontal surface or be lower than cabin floor.
In addition, this self dumping lorory back door jack Structure for door on door leaf can be the opposite opened Structure for door on door leaf, also can be laterally opened Structure for door on door leaf.
And, when described self dumping lorory back door jack Structure for door on door leaf is the opposite opened Structure for door on door leaf, the crack between a door and its frame buting iron being installed in the bottom and the outside portion of described door in door, the material phenomenon appears when preventing that described door in door from closing leaking.
When described self dumping lorory back door jack Structure for door on door leaf is laterally opened Structure for door on door leaf, in the bottom of described door in door the crack between a door and its frame buting iron is installed, the material phenomenon appears when preventing that described door in door from closing leaking.
The technology of self dumping lorory back door jack door in door of the present utility model is compared with original common self dumping lorory back door jack, the advantage and the good effect that are had are: the additional function of having realized self dumping lorory back door jack, dumping car can transport bag cargo, thereby but the traffic coverage of dumping car is strengthened, dumping car not only can transport loose unpacked material, also can transport bag cargo and packing-box design goods as general wagon.The transport benefits of dumping car is increased, user-friendly, satisfy user's interests maximization.
Description of drawings
Fig. 1 is that back door assembly with self dumping lorory back door jack Structure for door on door leaf of the present utility model is installed in the scheme drawing on the compartment.
Fig. 2 be the A of Fig. 1 to view, be opposite opened door in door assembly (remove with the compartment and be connected lockset).
Fig. 3 be the A of Fig. 1 to view, be laterally opened door in door assembly (remove with the compartment and be connected lockset).
Fig. 4 is the back doorframe structure scheme drawing of self dumping lorory back door jack Structure for door on door leaf of the present utility model.
Fig. 5 is the scheme drawing of dumping car opposite opened door in door assembly offside door.
Fig. 6 is the scheme drawing of the laterally opened door in door assembly of dumping car.
The specific embodiment
Be specifically described below in conjunction with structure, the principle of Figure of description self dumping lorory back door jack Structure for door on door leaf of the present utility model.
As shown in Figure 1, self dumping lorory back door jack door in door assembly 2 of the present utility model is installed on the back door assembly 1, this back door assembly 1 connects hinge 7 by the compartment and is connected with compartment 8, and this back door assembly 1 also is equipped with back door lockset 6 simultaneously, to guarantee the opening and closing function of original self dumping lorory back door jack.
Fig. 2 is an opposite opened door in door assembly structure, and Fig. 3 is laterally opened door in door assembly structure.Shown in Fig. 2,3, to open normally in order to realize back door door in door 2, this door in door 2 need be connected with back doorframe 5 with hinge 4 (being that door in door connects hinge), thus door in door 2 can rotate around back doorframe 5, and the realization back door is connected with back doorframe 5.The unlatching of door in door 2 and locking need the back door that door in door lockset 3 is installed, and described door in door lockset 3 selects for use freight container to carry out the opening and closing of door in door with the door lock tool.
Fig. 4 is the back doorframe structure scheme drawing of self dumping lorory back door jack Structure for door on door leaf of the present utility model.As shown in Figure 4, the back doorframe 5 of dumping car is to be welded by upper ledge 9, lower frame 10 and frame 11, and the last plane of lower frame is lower than cabin floor during design, perhaps with the dull and stereotyped level of base plate, to realize the smooth loading and unloading of bag cargo.
Shown in Figure 5 is the offside door of dumping car opposite opened door in door assembly, Reference numeral 13 expression clamshell doors offside door assembly crossbeams among the figure, 14 expression clamshell doors offside door assembly vertical beams, this door is welded according to diagramatic way by section bar, increased crack between a door and its frame buting iron 12 simultaneously, occurred leaking the material phenomenon when closing to prevent door.With the offside door symmetry, only be to increase time buting iron when offside door is made, middle buting iron needn't increase.
Shown in Figure 6 is the laterally opened door in door assembly of dumping car, the Reference numeral 23 expression sides assembly crossbeam that opens the door among the figure, the 24 expression sides vertical beam in the assembly that opens the door, the 25 expression sides assembly frame vertical beam that opens the door, this door is welded according to diagramatic way by section bar, only increases the crack between a door and its frame buting iron 12 of bottom.
Although the utility model is just represented with some forms, it will be apparent to one skilled in the art that under the situation that does not break away from the utility model scope, the utility model can have different distortion.
