Description
Technical field
The utility model belongs to railway carriage or compartment, compartment door locking device technical field, particularly a kind of anti-open locking device for torque arm car carriage back door.
Background technology
Torque arm car, it is a kind of conventional roll off skip loader, it possesses cargo dumping and casing automatic loading and unloading (namely self-contained whole unload) two kinds of functions simultaneously, operation and the conversion of these two kinds of functions are realized by hydraulic efficiency pressure system, and these two kinds of functions are completed by a vehicle-mounted equipment, and work efficiency is high.So torque arm car is widely used in the municipal administration of each environmental sanitation and large-scale factories and miness department, deliver various rubbish, the building materialss in bulk such as transport ash, sand, stone, soil, also can transport ore or coal in mine or colliery.
In the compartment use procedure of torque arm car, the goods in compartment can not be poured out, and this just requires that torque arm car carriage back door is in closed condition, so the locking of carriage back door just seems particularly important.In existing technology, the normally used rear door locking device of colleague producer is primarily of hydraulic oil cylinder driving connecting rod, connecting rod drives upper and lower latch hook to move, thus the locking action realized between envelope and back door, but envelope uses on the ground for a long time, locking cylinder can only maintain the lock status by hydraulic lock, if when locking cylinder is let out in occurring, back door locking will be lost efficacy, and the goods in compartment will be poured out outside compartment.
Utility model content
Leave standstill long-time the reliability that in process, compartment and carriage back door are locked in order to improve compartment, the utility model provides a kind of anti-open locking device for torque arm car carriage back door especially.
The technical solution adopted in the utility model is: a kind of anti-open locking device for torque arm car carriage back door, comprise latch hook, lower latch hook, locking cylinder, upper limit part, lower limit part, upper locking pin and lower locking pin, upper latch hook and lower latch hook are the rod member of one end with crotch, the middle part of upper latch hook and lower latch hook is hinged on the bottom of casing side, upper latch hook is positioned at the top of lower latch hook, piston rod and the upper latch hook of locking cylinder are hinged without one end of crotch, cylinder body and the lower latch hook of locking cylinder are hinged without one end of crotch, upper locking pin and lower locking pin are fixed on back door, one end of hook strip of locking crotch is articulated on locking pin, one end of lower latch hook band crotch is articulated on lower locking pin, for limiting the upper limit part of the upper latch hook anglec of rotation and the lower limit part for limiting the lower latch hook anglec of rotation is all fixed on casing.
Described lower latch hook is fixedly connected with without one end of crotch the locking rod preventing upper latch hook and lower latch hook from opening, described locking rod bottommost and casing bottom most position are on same level line, and when described locking rod and vertical curve have angle and be partial to latch hook to open, hand of rotation is reverse.
Described hitcher of locking has one end of crotch upwards to catch on locking pin, and one end that described lower latch hook has crotch catches on lower locking pin downwards.
The utility model compared with prior art has following beneficial effect.
1, locking cylinder is directly connected with upper and lower latch hook, and without the need to connecting rod mechanism, structure is simple, handled easily.
2, in the middle part of upper and lower latch hook, hinge is in the outer wall of side, compartment, and in use procedure, the anglec of rotation of upper and lower latch hook is limited by upper and lower limiting stopper and upper and lower locking pin respectively, and under realizing locking and opening, upper and lower latch hook position fixes.
3, during locking state, when locking rod and vertical curve have angle and be partial to latch hook to open, hand of rotation is reverse, when compartment is placed on ground, locking rod is kiss the earth also, like this, although locking cylinder is let out in may occurring, locking rod still can maintain the lock status the position of lower upper and lower latch hook, will carriage back door be caused surprisingly to open because of the inefficacy of locking cylinder.
4, the utility model respectively can be installed a set of in casing both sides, and form six point types with upper link point and lock, locking point is many, and strained condition is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model when being in opening.
Fig. 3 is the structural representation of lower latch hook and locking rod.
In figure: 1 is upper latch hook, 2 is lower latch hook, and 3 is locking cylinder, and 4 is upper limit part, and 5 is lower limit part, and 6 is upper locking pin, and 7 is lower locking pin, and 8 is casing, and 9 is back door, and 10 is locking rod.
Detailed description of the invention
As shown in Fig. 1 Fig. 2, a kind of anti-open locking device for torque arm car carriage back door of the utility model, comprise latch hook 1, lower latch hook 2, locking cylinder 3, upper limit part 4, lower limit part 5, upper locking pin 6 and lower locking pin 7, upper latch hook 1 and lower latch hook 2 are the rod member of one end with crotch, the middle part of upper latch hook 1 and lower latch hook 2 is hinged on the bottom of casing 8 side, upper latch hook 1 is positioned at the top of lower latch hook 2, piston rod and the upper latch hook 1 of locking cylinder 3 are hinged without one end of crotch, cylinder body and the lower latch hook 2 of locking cylinder 3 are hinged without one end of crotch, upper locking pin 6 and lower locking pin 7 are fixed on back door 9, upper latch hook 1 one end with crotch is articulated on upper locking pin 6, lower latch hook 2 one end with crotch is articulated on lower locking pin 7, for limiting the upper limit part 4 of upper latch hook 1 anglec of rotation and the lower limit part 5 for limiting lower latch hook 2 anglec of rotation is all fixed on casing 8.
Described lower latch hook 2 is fixedly connected with without one end of crotch the locking rod 10 preventing upper latch hook 1 and lower latch hook 2 from opening, described locking rod 10 bottommost and casing 8 bottom most position are on same level line, and when described locking rod and vertical curve have angle and be partial to latch hook to open, hand of rotation is reverse.
Locking pin 6 is upwards caught in one end that described upper latch hook 1 has crotch, and one end that described lower latch hook 2 has crotch catches on lower locking pin 7 downwards.
When latching device needs to open, locking cylinder 3 moves, and piston rod stretches out, and in drive, latch hook 1 rotates, upper latch hook 1 leaves locking pin 6 and opens, when upper limit part 4 encountered by upper latch hook 1, piston rod is obstructed no longer upward movement, and under action of hydraulic force, the cylinder body of locking cylinder 3 moves downward, lower latch hook 2 is driven to rotate, lower latch hook 2 leaves lower locking pin 7 and opens, and after upper and lower latch hook is all opened, back door 9 can be opened.When needing locking, the piston rod of locking cylinder 3 is regained, and upper latch hook 1 rotates and catches on locking pin 6, and lower latch hook 2 rotates and catches on lower locking pin 7, is locked at back door 9.
Rubbish container press-fit in process need ensure back door locking, in order to prevent because locking cylinder 3 accidental discharge of oil causes the unexpected unlatching in back door 9, be provided with locking rod 10, after back door 9 is locked, when compartment is placed on ground, locking rod 10 and earth surface, have angle due to locking rod and vertical curve and be partial to the reverse of hand of rotation when lower latch hook is opened, lower latch hook 2 cannot be rotated, reach anti-effect of opening.
