Abstract
The invention discloses a collision protection device of an electric forklift. The collision protection device comprises a base, the base is composed of a base plate and a U-shaped plate inverted on the upper end face of the base plate, and a top plate of the inverted U-shaped plate is an inclined plate. Installing bases are symmetrically installed at the left and right ends of the upper end face of the inclined plate, two limiting holes distributed at an interval are formed in each installing base, a rolling shaft is movably installed inside every two corresponding left and right limiting holes, an upper portion sliding plate is arranged on the installing bases and moves vertically in the inclination direction of the inclined plate, and the outer walls of the rolling shafts are attached to the upper end face of the inclined plate and the lower end face of the upper portion sliding plate. The collision protection device is reasonable in structural design, the number of components forming the overall device is small, the machining technology is simple, and the cost is low. When the forklift collides with the device, firstly, impact force is decomposed into two backward and upward component forces, speed is decreased for buffering until the forklift stops, in this way, it can be prevented that due to rigid collision, a wall or the forklift is damaged, materials on the forklift are impacted and damaged or toppled over, and the protection effect is very good.
Description
Technical field

Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
See accompanying drawing: electri forklift impact protection apparatus, comprise base 1, base 1 is made up of base plate 1-1 and the inverted U-board 1-2 in upper surface, be all movably installed with the axis of rolling 4 in the top board of inverted U-board 1-2 is hang plate, two ends, left and right, hang plate upper surface are symmetrically installed with mount pad 2, each mount pad 2 is provided with two spacing holes 3 spaced apart, two, left and right is corresponding spacing hole 3, mount pad 2 is provided with and fits along the up and down upper slide plate 5 of hang plate direction of tilt, the axis of rolling 4 outer wall and hang plate upper surface and upper slide plate 5 lower surface.
The spindle nose at the axis of rolling 4 two ends matches with spacing hole 3, and the shaft portion between spindle nose contacts with hang plate upper surface and upper slide plate 5 lower surface.
The spindle nose 4-1 diameter of axle of the axis of rolling 4 is generally 10mm, the axostylus axostyle 4-2 part diameter of axle is generally 20mm, during installation, spindle nose inserts mount pad 2, by the shaft shoulder as axial location, outer wall bottom is pressed on base, outer wall upper support upper slide plate 5, when fork truck collides, make the relative displacement occurred between upper slide plate 5 and base 1 be friction of rolling, reduce resistance.In its natural state, due to the effect of gravity, the axis of rolling glides, and two spindle noses snap into the lower edge of the spacing hole 3 on mount pad 2, when upper slide plate 5 contacts with fork truck, roll between upper slide plate 5 and the axis of rolling 4.
Mount pad 2 is bar shaped block, and bar shaped block is installed along the top board direction of tilt of inverted U-board 1-2, and the spacing hole 3 that bar shaped block is arranged is bar hole, and bar hole is arranged along interval, bar blocks body length direction.
The height of mount pad 2 is less than the external diameter of the axis of rolling 4 shaft portion, is generally 19mm, is less than the axis of rolling 4 external diameter, to ensure the gap having about 1mm between upper slide plate 5, touches when preventing upper slide plate 5 from moving.
The each corner of upper slide plate 5 is arranged with movable mounting hole 6, run through in movable mounting hole 6 and have half-thread bolt 7, the thread segment of half-thread bolt 7 extend into the top board internal fixtion of inverted U-board, and it is standby tight with nut at base intracavity, the polished rod part of half-thread bolt 7 is positioned at movable mounting hole 6, and polished rod top root and upper slide plate 5 lower surface of half-thread bolt 7 are provided with gap.
Movable mounting hole 6 is arranged along inverted U-board top board direction of tilt interval, and movable mounting hole 6 width is greater than half-thread bolt 7 polished rod segment outer radius, and the width of movable mounting hole 6 is generally 17mm.
Gap is generally 0.5 ~ 1.5mm, upper slide plate 5 can not be killed, only play the guiding role, in order to avoid cause slide plate to move; And in its natural state, due to the effect of gravity, slide plate glides, the upper limb of movable mounting hole snaps on half-thread bolt 7, when upper slide plate 5 contacts with fork truck, moves rearwardly and upwardly along the axis of rolling 4 below with fork truck.
Whole device is finally fixed on the ground of desired location with expansion bolt by base of the present invention.
Mount pad 2 is also provided with and has 3 counter sinks perpendicular to its direction, upper and lower end face, is fastened on base with socket cap screw.
Spacing hole 3 is used for installing the axis of rolling 4 for strip hole that side direction is offered, is free-running fit, and smears appropriate clean room special grease between spacing hole 3 and the axis of rolling 4, smooth and easy during to ensure that the axis of rolling moves.
When fork truck and upper slide plate touch, the impact of horizontal direction is broken down into two power of vertical slide and vertical direction, therefore, whole device is two power of and fork truck sense of motion opposing force and a picking-up fork truck upwards to the antagonistic force of fork truck, stop fork truck to continue to move backward on the one hand, fork truck wheel can be lifted away from ground gradually on the other hand.When wheel be in leave ground transformation point time, and without application force between ground, can not continue move to the direction of wall with electrical forklift, play a protective role.In this knockout process, fork truck is not rigid collision therewith between device, but a buffering course, can play a protective role to fork truck, also can ensure that the goods that fork truck loads can not topple because of rigid collision or damage simultaneously.
According to mechanical model, upper surface and base angle larger, then the power of vertical direction after decomposing is less, and the power of vertical upper slide plate is larger, and collision is got over close to rigid collision; Vertical direction power after the less decomposition of angle is larger, and the power of vertical upper slide plate is less, and fork truck slips larger distance after may continuing due to inertia after wheel lift, so all can reduce defencive function.Therefore, between upper surface and base, angle 45 degree is the most reasonable.
