Abstract

The utility model discloses a hydraulic directional wheel structure four-way operation forklift, including a forklift body, a front wheel is respectively mounted on the two front wheel carrier, oil cylinders are respectively mounted on the two fork legs, the piston-rods of the oil cylinder are respectively hinged on the inner side of the corresponding front wheel carrier, a drive wheel and a universal wheel are respectively mounted on both side the of the rear end bottom of the forklift body. The utility model has operation functions that it can longitudinally advance and retreat and turn as the general forklift, and also can lateral direction advance and retreat and turn, the operation function is stronger, the maneuverability can be better, the running performance is better, and has simple structure and lower cost.

Description

A kind of hydraulic pressure directional wheel structure four-way operation fork truck

Technical field:

The utility model relates generally to a kind of material conveying device, relates in particular to a kind of hydraulic pressure directional wheel structure four-way operation fork truck.

Background technology:

The pattern that turns in the existing fork truck technology is an important system of fork truck, especially for four-way operation fork truck.At present, the cardan wheel structure that four-way operation fork truck on the market adopts a drive wheel, a directed structural load front-wheel (this load front-wheel can turn to 90 °), two diagonal angles to arrange mostly, though it is simple in structure, cost is lower, but under factor affecting such as frictional ground force, the variation of car load center of gravity, road conditions, the follow-up steering of two cardan wheels is not consistent, causes big adverse effect thereby vehicle performance is especially exercised performance, and driving and the performance of Parking process are particularly serious; Or adopt a drive wheel, a back supplemental support cardan wheel, two oriented load front-wheels (this load front-wheel can turn to 90 °) structure, and this structure direction load front-wheel steering passes through realizations such as motor, speed-changing mechanism, angular transducer, complex structure, and cost is higher.

The utility model content:

The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of enforcement functional, and simple in structure, lower-cost hydraulic pressure directional wheel structure four-way operation fork truck.

The utility model is achieved through the following technical solutions:

A kind of hydraulic pressure directional wheel structure four-way operation fork truck, include the fork truck body, it is characterized in that: the bottom of two forks of described fork truck body front end leg is separately installed with front wheel carrier, be separately installed with front-wheel on two front wheel carriers, be separately installed with oil cylinder on described two fork legs, the piston rod of oil cylinder is hinged on the inboard of cooresponding front wheel carrier respectively; Described fork truck body rear end two bottom sides is separately installed with drive wheel and cardan wheel.

A kind of hydraulic pressure directional wheel structure four-way operation fork truck, it is characterized in that: the bottom of described two fork legs is fixed with disc shaped front-wheel upper plate respectively, the downside of two front-wheel upper plates is rotatablely equipped with front wheel carrier respectively, be respectively arranged with limiting stopper on the upper surface of front wheel carrier, be fixed with the block that can stop that corresponding limiting stopper rotates on the ring edge of described front-wheel upper plate respectively.

Described front-wheel is the load front-wheel, and the load front-wheel is the directional wheel structure, can turn to 90 °, and the promotion of this load front-wheel by the oil cylinder piston bar realizes the purpose that turns to.Two oil cylinders dispose hydraulic lock respectively, when the needs wheel position locks, to in-oil cylinder hydraulic oil sealing, to keep the wheel position state.

Described oil cylinder is controlled the fore and aft motion of its upper piston rod by multiway valve, and described multiway valve is provided with operating handle.Described drive wheel direction of passage dish is controlled its direction.

The utility model initial condition is vertical walking states, when needs are converted into horizontal walking states, need carry out following operation: at first, pull the multiway valve operating handle, making the piston rod of oil cylinder promote the front wheel carrier moving axis that rotates rotates, when treating that front wheel carrier rotates 90 °, block blocks limiting stopper, and front wheel carrier stops operating.At this moment, two load front-wheels are transformed into the cross-tie wheel.Afterwards, steering wheel rotation makes drive wheel turn to 90 °, and is parallel with two load front-wheels, thereby the utility model is to switch to lateral rows mule carriage train from vertical running wheel, and this moment, the utility model can laterally move.

Pull the multiway valve operating handle, make the piston rod withdrawal of oil cylinder, the load front wheel carrier rotates and gets back to load front-wheel lengthwise position, and steering wheel rotation makes drive wheel parallel with front-wheel, thereby reverts to vertical Running System Wheeling System from horizontal Running System.

The utility model has the advantages that:

The utility model operation function can also laterally advance and retreat and turn to except that equally can vertically advancing and retreat and turn to general fork truck, and operation function is stronger, and maneuvering performance is better, and rideability is better, and simple in structure, cost is lower.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

A kind of hydraulic pressure directional wheel structure four-way operation fork truck, include fork truck body 1, the downside that the bottom of two of described fork truck body 1 front ends fork leg 2 is fixed with 9, two front-wheel upper plates 9 of disc shaped front-wheel upper plate respectively is rotatablely equipped with respectively on 3, two front wheel carriers 3 of front wheel carrier and is separately installed with front-wheel 4.Be separately installed with oil cylinder 5 on described two fork legs 2, the piston rod 6 of oil cylinder 5 is hinged on the inboard of cooresponding front wheel carrier 3 respectively.Be respectively arranged with limiting stopper 11 on the upper surface of front wheel carrier 3, be fixed with the block 10 that can stop that corresponding limiting stopper 11 rotates on the ring edge of described front-wheel upper plate 9 respectively.Described fork truck body 1 rear end two bottom sides is separately installed with drive wheel 7 and cardan wheel 8.
