Abstract

The utility model relates to a pallet pusher for forklift attachments, which is used along with a rotary push-pull attachment for forklifts. The pallet pusher for forklift attachments comprises a fork base and a pallet push-pull mechanism; the pallet push-pull mechanism comprises a left connecting arm, a right connecting arm, a left driving arm, a right driving arm, a push-pull oil cylinder, a left roller and a right roller; and the pallet push-pull mechanism is mounted on the fork base through an articulating support and a guide way. The pallet pusher combined with the rotary push-pull attachment for forklifts can implement the function of automatically pushing out a pallet, saves manpower, is convenient to use, increases working efficiency, and reduces cost.

Description

Lift truck attachment pallet pusher

Technical field

The utility model relates to and the matching used attached tooling device of fork truck, it is characterized in that realizing the automatic release of pallet.

Background technology

In industries such as food, automated production, article recovery, chemical industry, generally some stacks of cargo for the treatment of that entrucking is transported are placed on the pallet, choose with fork truck then that pallet transports or stacking, but when entrucking, preferably pallet is taken out, take out the cost that the pallet entrucking had not only increased the loading amount of car but also saved pallet; The general fork truck that rotation push-and-pull accessory is housed that adopts of factory satisfies top operating mode, but present fork truck rotation push-and-pull accessory also needs extra artificial assisting could realize this operating mode when taking out pallet.

Therefore, prior art awaits further improving and development.

Summary of the invention

Degree of automation when improving the fork truck shipment reduces the shipment manpower, and the utility model provides a kind of lift truck attachment pallet pusher.

Concrete structural design scheme is as follows:

Lift truck attachment pallet pusher comprises pallet fork base 3 and pallet push-pull mechanism;

Pallet fork base 3 both sides are equipped with hinged support 4 and guide-track groove 9, and described guide-track groove 9 is the channel-section steel shape; Left side connecting arm 6 one sides are installed in the hinged support 4, and can rotate, and left connecting arm 6 opposite sides and right master arm 10 1 sides are rotationally connected, and left connecting arm 6 middle parts and right connecting arm 7 middle parts are rotationally connected; Right connecting arm 7 one sides are provided with center bearing pilot bearing 14, and this center bearing pilot bearing 14 is positioned at guide-track groove 9, and right connecting arm 7 opposite sides and left master arm 11 are rotationally connected; Left side master arm 11 and right master arm 10 middle parts are rotationally connected, and left master arm 11 heads are provided with right roller 12, and right master arm 10 heads are provided with left wheel 8; The cylinder body afterbody of push cylinder 5 is installed on the hinged support 4, can rotate, and the rod end of push cylinder 5 and right master arm 10 middle parts are rotationally connected by the position, back.

Described pallet push-pull mechanism stretches out occiput roller position and pallet fork 13 hangings, and shrinking the occiput position can not be above the release flat board 2 in the fork truck rotation push-and-pull accessory.

The utlity model has the advantage of the following aspects: (1) this lift truck attachment pallet pusher compact conformation, release the lucky and bottom pallet fork equal in length in back, retracting each connecting arm of back and master arm can overlap by composition, and quality is little, can not influence the normal operation of fork truck hydraulic efficiency pressure system; (2) the employed push cylinder volume of this pusher is little, from heavy and light, and has fabulous hiding protectiveness; (3) this pusher can relaxedly and rapidly realize releasing automatically the function of pallet, has saved manpower; (4) this device is reasonable in design, and stable working is reliable, and cost is low, detects easy to maintenance.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is in the contraction state scheme drawing for pusher.

Fig. 3 releases the pallet view for pusher is in.

Fig. 4 is the utility model birds-eye view.

Sequence number among the figure: fork truck rotation push-and-pull accessory 1, release flat board 2, pallet fork base 3, hinged support 4, push cylinder 5, left connecting arm 6, right connecting arm 7, left wheel 8, guide-track groove 9, right master arm 10, left master arm 11, right roller 12, pallet fork 13, center bearing pilot bearing 14.

The specific embodiment

Below in conjunction with accompanying drawing, do to describe further by the present invention of embodiment.

Referring to Fig. 1 and Fig. 4, lift truck attachment pallet pusher is installed in below the rotation push-and-pull accessory, comprises pallet fork base 3 and pallet push-pull mechanism.Pallet fork base 3 both sides trailing flanks are connected with pallet fork 13 dogleg section; Pallet fork base both sides leading flank is equipped with hinged support 4 and guide-track groove 9, and described guide-track groove 9 is the channel-section steel shape; Left side connecting arm 6 one sides are installed in the hinged support 4, and can rotate, and left connecting arm 6 opposite sides and right master arm 10 1 sides are rotationally connected, and left connecting arm 6 middle parts and right connecting arm 7 middle parts are rotationally connected; Right connecting arm 7 one sides are provided with center bearing pilot bearing 14, and this center bearing pilot bearing 14 is positioned at sliding tray 9, can be in sliding tray 9 sway, right connecting arm 7 opposite sides and left master arm 11 are rotationally connected; Left side master arm 11 and right master arm 10 middle parts are rotationally connected, and left master arm 11 and right master arm 10 head positions are installed with two pulleys respectively; The cylinder body afterbody of push cylinder 5 is installed on the hinged support 4, and the rod end of push cylinder 5 is connected with right master arm 10, and this oil cylinder is two-way cylinder, and the hydraulic valve of controlling this oil cylinder is installed in is convenient to the navigating mate operating position on the fork truck.

Referring to Fig. 2, the pallet push-pull mechanism stretches out, the head pulley 8 of push-pull mechanism, 12 and pallet fork 13 hangings; Referring to Fig. 3, shrink the occiput position and can not interfere with the release flat board 2 that fork truck rotates on the push-and-pull accessory.

During use, pallet pusher and rotation push-and-pull accessory cooperating; During beginning, the pallet pusher shrinks, can not interfere the operation of rotation push-and-pull accessory, after accessory fork installs goods and Rotate 180 °, be in Fig. 3 and show state, at this moment operating elevating ram (in the rotation push-and-pull accessory corresponding elevating ram being arranged) rises basetray 3, pallet just separates with goods and can take out pallet like this, show as Fig. 2, operation hydraulic valve (being installed in the position of truck driver handled easily) stretches out push cylinder 5 piston rods, promote to push away before connecting arm and the master arm, so just pallet can be released, catch pallet, two effects that pulley plays to reduce to rub of master arm front for avoiding pallet directly to land damaging that a highly suitable support can be set; If the utility model pallet pusher is not installed, just need manually take off pallet, labor intensive.
