The locking rod assembly comprises a rotary base, a connection rod and a rotary forked base, wherein the left end of the rotary base is rotatably installed on the installation base, a connection plate is hinged between the right end of the rotary forked base and the left end of the locking hook, and two ends of the connection rod are fixedly connected with the right end of the rotary base and the left end of the rotary forked base. The rear door locking mechanism is simple in structure, convenient to manufacture, fast in response, strong in locking force and not apt to fail, provides technology guarantee for safe and sanitary transportation, is high in locking hook strength and not apt to deform, and ensures forceful rear door locking, the two ends of the connection rod are in thread connection with the rotary base and the rotary forked base respectively, the length can be adjusted, the rear door can be locked, universality is improved, and the rear door locking mechanism is suitable for dumpers with different rear suspensions.
Description
Technical field
The utility model relates to self-unloading class special-use vehicle field, specifically is a kind of self dumping lorory back door jack catch gear.
Background technology
Self-unloading class special-use vehicle is called for short dumping car, refers to by hydraulic pressure or mechanical lifting and the vehicle of unloaded of cargo voluntarily, claims tip lorry again.Formed by parts such as car chassis, hydraulic lifting mechanism, container and power takeoffs.
Existing self dumping lorory back door jack catch gear mostly is chain structure, and reaction is slow, and coupling mechanism force is not enough, and the time has been grown easy inefficacy; And common rigidity catch gear, intensity difference makes that the back door coupling mechanism force is not enough, easy deformation lost efficacy.
The utility model content
The purpose of this utility model provides a kind of being swift in response, and coupling mechanism force is strong, is difficult for the rigidity self dumping lorory back door jack catch gear that lost efficacy.
The technical solution of the utility model is as follows:
A kind of self dumping lorory back door jack catch gear, include mount pad, locking bar assembly, bearing and latch hook, it is characterized in that: described mount pad is fixedly mounted on the crossbeam of container chassis afterbody, described bearing is fixedly welded on the bottom of container tail end, and the end of described latch hook is rotatably installed on the bearing; Described locking bar assembly includes rotary seat, connecting rod and rotation forked standard, the left end of described rotary seat is rotatably installed on the mount pad, being hinged with connecting panel between the right-hand member of described rotation forked standard and the end of latch hook, captives joint with the left end of rotation forked standard with the right-hand member of rotary seat respectively in the two ends of described connecting rod.
Described self dumping lorory back door jack catch gear is characterized in that: described mount pad is installed on the transom beam of car body chassis by bolt.
Described self dumping lorory back door jack catch gear, it is characterized in that: the two ends of described connecting rod are respectively equipped with outside thread, the left end of the right-hand member of described rotary seat and rotation forked standard is respectively equipped with negative thread, and the two ends of described connecting rod are threaded with the right-hand member of rotary seat and the left end of rotation forked standard respectively.
The beneficial effects of the utility model:
Of the present utility model simple in structure, easy to make, be swift in response, coupling mechanism force is strong, be not easy to lose efficacy, for the safety and sanitation transportation provides technical guarantee, its latch hook intensity height, not yielding, guaranteed the strong locking in back door, the connecting rod two ends are threaded respectively with rotary seat and rotary socket, can regulate length, both the back door can be locked, improve commonality again, gone for the dumping car of different rear overhangs.
Description of drawings
Fig. 1 is the front view of the utility model structure.
Fig. 2 is the birds-eye view of the utility model structure.
The specific embodiment
Referring to Fig. 1,2, a kind of self dumping lorory back door jack catch gear includes mount pad 1, locking bar assembly, bearing 2 and latch hook 3, and mount pad 1 is fixedly mounted on the crossbeam of container chassis afterbody, bearing 2 is fixedly welded on the bottom of container tail end, and the end of latch hook 3 is rotatably installed on the bearing 2; The locking bar assembly includes rotary seat 4, connecting rod 5 and rotation forked standard 6, the left end of rotary seat 4 is rotatably installed on the mount pad 1, being hinged with connecting panel 7 between the right-hand member of rotation forked standard 6 and the end of latch hook 3, captives joint with the left end of rotation forked standard 6 with the right-hand member of rotary seat 4 respectively in the two ends of connecting rod 5.
In the utility model, mount pad 1 is installed on the transom beam of car body chassis by bolt; Connecting rod 5 is the 45# round steel, and its two ends are respectively equipped with outside thread, and the left end of the right-hand member of rotary seat 4 and rotation forked standard 6 is respectively equipped with negative thread, and the two ends of connecting rod 5 are threaded with the right-hand member of rotary seat 4 and the left end of rotation forked standard 6 respectively.
When the container lifting, the locking bar assembly promotes latch hook 3 forward by connecting panel 7, and latch hook 3 clockwise rotates, with the back door apart from increasing, open at the back door; When container descended, the locking bar assembly pulled back latch hook 3 by connecting panel 7, and latch hook 3 rotates counterclockwise, and reduced with the back door distance, until compressing the back door, realized the back door is locked.
