Abstract
The pallet fork be assemblied on automobile fork truck tightens up a self-locking device, and before using for pallet fork, pull-out launches, and locks, do not need pivot pin on Assembly &Disassembly, be very easy to the use of fork truck with superimposed playback of pallet fork after use; Eliminate because there being self-marketing function and take-up the slack, eliminate and vibrate in driving, cause pallet fork and upper pivot pin, cushion pivot pin and collide the damage causing pallet fork.
Description
Technical field
The utility model is the parts of the extension on fork truck, belongs to lifting and haulage equipment field.
Background technology
Before using powered forklift vehicle operation, pallet fork needs pull-out to be deployed into control position, and after fork truck fulfils assignment, pallet fork needs to draw playback in be fixed; It is with lower shaft pin carrying that current playback has a kind of method preferably to fix pallet fork, pallet fork constraint is pinned by installing pivot pin; When pallet fork pull-out launches, need to untie spring set pin, upper hinge pin disassembling is extracted; When drawing playback in and being fixing, need mounting spring set pin, therefore, bring three problems: one is install pivot pin, and in dismounting, pivot pin is pretty troublesome; Two be and also the upper pivot pin volume that unloads little, now easily easily lose in mixed and disorderly construction, not easily find; Three is that pallet fork is sandwiched between upper and lower pivot pin, and fixed range between upper and lower pivot pin, always there is gap, make powered forklift vehicle in walking because of vibration, cause the collision between pallet fork and upper lower shaft pin, easily cause the damage of pallet fork and pivot pin impingement area.
Summary of the invention
Accordingly, the utility model provides a kind of pallet fork be assemblied on automobile fork truck to tighten up self-locking device, and before using for pallet fork, pull-out launches, and after pallet fork uses, pallet fork playbacks superimposed locking, does not need pivot pin on Assembly &Disassembly, is very easy to the use of fork truck.
The technical solution of the utility model:
The lower end of U-shaped frame, is equipped with buffering pivot pin, from the upper face of cylinder of buffering pivot pin, up moves the thickness distance of pallet fork, installs lock body case, the bottom of lock body case and the mounting plane of U-shaped frame, assembles (omitting in accompanying drawing) with threaded fasteners; In lock body case, dead bolt is installed; Lock tongue upper surface is shaped with slippage inclined-plane, and lock tongue lower surface is shaped with wedging inclined-plane, is convenient to lock pallet fork, and dead bolt rear portion is equipped with rear bar and pressure spring is housed; The rear shank portion end of dead bolt is bending or is other shapes conveniently pulled.
The slippage inclined-plane of lock tongue and level angle α are at 40-50 degree, and wedging inclined-plane and horizontal angle beta are at 5-20 degree.
The beneficial effects of the utility model: powered forklift vehicle operating personal, very convenient pull-out launches pallet fork and carries out the operation of fork goods, after operation completes, easily superimposed for pallet fork recurrence can be tightened up, save the trouble that pallet fork pull-out is playbacked with pallet fork, eliminate because there being auto-lock function and take-up the slack, eliminate and in driving, to vibrate pallet fork and upper pivot pin, cushion pivot pin and collide the damage causing pallet fork.
Accompanying drawing explanation
By reference to the accompanying drawings the utility model is explained.
Fig. 1 is structural principle section-drawing of the present utility model.
Fig. 2 is application of the present utility model assembling schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described.
Containing signal part, the utility model general assembly accessory numbering that whippletree "-" is the utility model functions in icon.
Dead bolt 3 is assembly sets, is combined by dead bolt 3 rear bar cover upper spring 4, is arranged in lock body case 5; Two pallet forks tighten up self-locking device 1-1, by U-shaped frame 1 bottom mounting apertures on it, are assemblied in the accurate location on car body by threaded fasteners symmetry, note the distance when upset of pallet fork 2-2 is regained and height.
Pallet fork 2-2 returns original position; Rotate centered by pallet fork pivot pin 3-3, pallet fork 2-2 is put into pallet fork and tightens up self-locking device 1-1; Rely on power and force of inertia for support, pallet fork 2-2 oppresses the bevelled dead bolt 3 of tool, because of the effect of horizontal component of force, dead bolt 3 is moved back by pressure, dead bolt 3 is resisted spring 4 power and to be retracted original position by brute force, retreats to compressed-bit, by dead bolt 3 along with pallet fork 2-2 compresses dead bolt 3, drop on buffering pivot pin 2, now, dead bolt 3 oppresses outwards motion, at lower inclined plane by pallet fork 2-2 wedging by the elastic force of spring 4, eliminate gap, final pallet fork 2-2 is pinned completely.
Pull-out pallet fork 2-2 is to working position; With the bending end pulling dead bolt 3 rear bar, dead bolt 3 is drawn into lock body case 5, pallet fork 2-2 unlocks, and just can upwards overturn, by the device that goes out of lock, turn to working position forward, pallet fork 2-2 steadily falls, and just can carry out the fork goods operation of pallet fork 2-2, now, dead bolt 3, under the effect of spring 4 power, reverts to the state of stretching out.
