Abstract

The utility model discloses a wide-view three-joint working device of a forklift, comprising an external door frame, a middle door frame, an inner door frame, a rear lifting oil cylinder assembly, a cargo fork frame, a cargo fork and two groups of chain wheel and chain assemblies, wherein the bottom end of the rear lifting oil cylinder assembly is connected with a bottom plate in the outer door frame; the upper end of the rear lifting oil cylinder assembly is connected with a cylinder head seat in the inner door frame; and one end of a rear chain assembly in each one of the two groups of the chain wheel and chain assemblies is connected with a chain seat on the outer door frame and a chain winds bypasses a chain wheel in an upper cross beam assembly in the door frame, and the other end of the rear chain assembly is fixedly arranged on an inner door frame chain seat. According to the wide-view three-joint working device of the forklift disclosed by the utility model, a steel groove of the door frame is shorter than two sections of common door frame groove steel; compared with a common three-grade full-freedom lifting mechanism, the lifting system has the advantages that a front lifting oil cylinder is omitted and a view space in the door frame is kept; and a good view range is kept for a forklift operator so that the operation is convenient and the safety of operation is improved.

Description

A kind of wide visual field fork truck three joint equipments
Technical field
The utility model relates to fork truck hoisting system device, the fork truck three joint door frames that especially relate to the wide visual field equipment that hoists.
Background technology
The fork truck equipment is the on-line operation mechanism that fork truck carries out loading and unloading operation.The fork unloading of the goods pile of putting, go up and down all accomplish by equipment, so the fork truck equipment is one of important component part of fork truck.
Fork truck such as need get in the warehouse, freight container at the job space that limitation in height is arranged; Require fork truck can pass through short warehouse or container door; Again can be through goods being given rise to more than 4 meters behind the door; So the three grades of complete free equipments that just have been born, it need increase a preceding lift cylinders and a running block, makes cost increase.
When the user only need satisfy the pallet loading fork truck or the demand in the short space passed through and when needs do not carry out the operation of high goods yard in short space; The function of three grades of complete free equipment high goods yard operation wherein change car load height just becomes surplus, is a kind of waste.
Traditional fork truck hoisting system mainly is divided into three kinds: the accurate hoisting system of two feast-brand marks, the complete free hoisting system of two-stage, three grades of complete free hoisting systems.Develop rapidly along with market economy; Increasing carrying, stacking operation are asked in narrow, short and small space, accomplish; This just requires the fork truck hoisting system when meeting the requirements of lifting altitude, has short as far as possible door frame height and unobstructed sight scope, operating characteristic.Simultaneously, along with market competition is fierce day by day, when satisfying the properties of product requirement, reduce the emphasis that the production manufacturing cost also becomes increases the market competitiveness.
Though the prior lifting system can satisfy the requirement of lifting altitude on the market; But exist other deficiency and defective: the accurate hoisting system of two feast-brand marks; When reaching lifting altitude and require, door frame lands overall height than higher, is difficult to satisfy the requirement through narrow short and small storehouse door; The complete free hoisting system of two-stage is when reaching the lifting altitude requirement, and door frame lands overall height also will be greatly than three grades of complete free hoisting systems, the existence of the cylinder that hoisted before the while, and retaining has gone to most of visual field in chaufeur dead ahead, extremely is unfavorable for operating; Three grades of complete free hoisting systems land the overall height size though have less door frame when reaching lifting altitude and require, the same because existence of preceding hoist cylinder, and retaining has gone to the visual field of chaufeur, is prone to cause operation inconvenience to produce danger.
The utility model content
The technical matters that the utility model solves is, a kind of three joint door frames of the wide visual field equipment that hoists is provided.
For solving the problems of the technologies described above, the technical scheme of the utility model is following:
A kind of wide visual field fork truck three joint door frames equipment that hoists; Comprise outer mast, middle door frame, inner upright mounting, back lift oil tank assembly, goods shelf, pallet fork and two groups of sprocket wheel chain assemblies; Back lift oil tank assembly bottom is connected with base plate in the outer mast, and back lift oil tank assembly upper end is connected with cylinder head seat in the inner upright mounting; Rear chain assembly in two groups of sprocket chain devices; One end is connected with chain stays on the outer mast, the sprocket wheel during chain is walked around in the door frame entablatrance assembly, and the other end is fixed on the inner upright mounting chain stays; Preceding chain assembly in two groups of sprocket wheel chain assemblies; One end is connected with chain stays on the middle door frame, and chain is walked around the sprocket wheel in the inner upright mounting entablatrance assembly, and the other end is fixed on the goods shelf chaining plate.
Compared with prior art, the beneficial effect of the utility model is:
Three joint door frame hoisting systems are under the requirement that guarantees equal lifting altitude, and door frame channel-section steel length shortens in common two joint door frame channel-section steel length; Compared to three grades of common complete free hoisting systems, this hoisting system has saved preceding hoist cylinder, has kept door frame in-to-in visual-field space, for the forklift operator person has kept the unobstructed sight scope, is convenient to operation, and has improved the safety when operating.

Fig. 3 is the assembling decomposing schematic representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done further detailed explanation:
Referring to Fig. 1 to Fig. 3; The shown a kind of wide visual field fork truck three joint door frames equipment that hoists; Comprise outer mast 1, middle door frame 2, inner upright mounting 3, back lift oil tank assembly 4, goods shelf 5, pallet fork 6 and two groups of sprocket wheel chain assemblies; Back lift oil tank assembly 4 bottoms are connected with base plate 7 in the outer mast 1, and back lift oil tank assembly 4 upper ends are connected with cylinder head seat 8 in the inner upright mounting 3; Rear chain assembly 9 in two groups of sprocket wheel chain assemblies; One end is connected with chain stays 10 on the outer mast 1, the sprocket wheel 11 during chain is walked around in the door frame 2 entablatrance assemblies, and the sprocket wheel 11 during the other end is walked around in the door frame 2 is connected with the chaining plate 12 in the inner upright mounting 3; Preceding chain assembly 13 in two groups of sprocket wheel chain assemblies; One end is connected with chain stays 10 on the middle door frame 2, and chain is walked around the sprocket wheel 11 in the inner upright mounting 3 entablatrance assemblies, and the other end is fixed on the goods shelf 5 chaining plates 14.
Shown in Figure 4 is exactly the integral structure scheme drawing of the utility model.
