Abstract
The invention discloses a kind of locking and unlocking mechanism of tailgate of dump truck carriage body, the dumping truck casing comprises base plate after cross member and back shield; Described base plate after cross member is provided with 1 or a plurality of lockholes side by side, corresponding 1 or a plurality of dead bolt that matches with it that be provided with of back shield; Each this dead bolt connects a hydraulic ram that is used to drive described dead bolt locking and unlatching by connecting rod.The catch gear of this locking and unlocking mechanism of tailgate is by the lockhole that is arranged on the base plate after cross member and be arranged on the back shield upper lock tongue and work in coordination and finish, and this locking pattern is firm reliable, and impact resistance is strong, so not yielding no leak.Realize locking and open back shield by stretching of connecting rod control dead bolt with hydraulic ram.This locking and opening structure are solid and reliable, and be sturdy and durable, and cost simple in structure is low easy for installation.
Description
Technical field
The invention belongs to the auxiliary mechanism of dumping truck casing, be specifically related to the improvement that the locking and the opener of casing back shield are done.
Background technology
The back shield of dumping car is normally locked back shield jointly by rigidity open-and-close mechanism and manual locking device.This device is in use found: when handling load had flowing power, even install sealing band additional at back shield, the remote transportation of general latching device also was easy to occur loosening, and then the seepage phenomenon occurs, has caused the pollution of road pavement.The building engineering self-discharging transporter is when the stronger goods of impact such as transportation rock etc., and dumping car goods in the unloading process can carry out impact to back shield, causes the back shield gross distortion, has influenced the attractive in appearance of car load.In this case, we are attempting the raising technological requirement, have increased cost virtually but do like this.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of locking and unlocking mechanism of tailgate of dump truck carriage body is provided, the simple shock resistance of this mechanism structure, no leak.
Below introduce structure of the present invention in detail, a kind of locking and unlocking mechanism of tailgate of dump truck carriage body, the dumping truck casing comprises base plate after cross member and back shield; Described base plate after cross member is provided with 1 or a plurality of lockholes side by side, corresponding 1 or a plurality of dead bolt that matches with it that be provided with of back shield; Each this dead bolt connects a hydraulic ram that is used to drive described dead bolt locking and unlatching by connecting rod.
Optimally, described hydraulic ram setting plays the spacing guide bracket of restriction dead bolt stroke effect.
Optimally, its concrete structure is that dead bolt overlaps the captive joint connecting rod through lock, and spacing guide bracket is provided with guide rail, and connecting rod and hydraulic ram are hinged in described guide rail.
Optimally, tailgate of dump truck carriage body is provided with 2 groups or 3 groups of lockholes and spring bolt mechanism.
Advantage of the present invention is arranged on the lockhole of base plate after cross member and is arranged on the back shield upper lock tongue and works in coordination, and this locking pattern is firm reliable, and impact resistance is strong, so not yielding no leak.Realize locking and open back shield by stretching of connecting rod control dead bolt with hydraulic ram.This locking and opening structure are solid and reliable, and be sturdy and durable, and cost simple in structure is low easy for installation.
Description of drawings
Figure of description 1 is a structural representation of the present invention;
Figure of description 2 is the connection diagram of dead bolt part of the present invention;
Figure of description 3 is the scheme drawing of lockhole of the present invention.
The specific embodiment
Below in conjunction with Figure of description invention is done further to disclose.
Embodiment 1:
See also Figure of description 1, Fig. 2, Fig. 3, a kind of locking and unlocking mechanism of tailgate of dump truck carriage body, dumping truck casing comprise base plate after cross member 11 and back shield 12; Described base plate after cross member 11 welding 1 or a plurality of lockholes 10 side by side, present embodiment is provided with two lockholes 10; Back shield 12 corresponding 2 dead bolts 9 that match with it that are provided with; Each this dead bolt 9 connects a hydraulic ram 1 that is used to drive described dead bolt locking and unlatching by connecting rod 5.Its concrete structure is that hydraulic ram 1 usefulness hexagon thin nut links to each other with oil cylinder journal stirrup 2, with lock shaft oil cylinder journal stirrup 2 is connected in the guide rail of spacing guide bracket 3 with the journal stirrup 4 of locking a door, and oil cylinder journal stirrup 2 forms hinged in the guide rail of spacing guide bracket 3 with the journal stirrup 4 of locking a door like this; The journal stirrup 4 of locking a door is connected with connecting rod 5 usefulness hexagon thin nuts, connecting rod 5 is pitched 6 with door lock company be connected with being equipped with jack panel, door lock connected pitch 6 and captive joint with door lock end ear 7, door lock end ear 7 is overlapped 8 with lock captives joint, lock cover 8 is captiveed joint with dead bolt 9, and dead bolt 9 is just with the flexible turnover lockhole 10 of hydraulic ram 1 like this.Spacing guide bracket 3 is welded on back shield 12 panels, lockhole 10 is welded on the base plate after cross member 11.Assembling is finished.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
