Abstract

The utility model discloses a fork-lift truck large arm rotation device which is provided with a lengthened arm horizontally hinged to a connecting frame, and a raising arm cylinder hinged to a support which is arranged on the lengthened arm. A second arm is hinged between the other end of the raising arm cylinder and the front-mounted end of the lengthened arm. An excavator bucket cylinder is hinged between the front-mounted end of the second arm and a hinge seat arranged on the second arm through a hinge bar. A steering cylinder is horizontally hinged between the lengthened arm and the connecting frame. The work surface is enlarged by above 80%, simultaneously the number of moving of the whole device can be relatively reduced because of the enlarged working surface, thereby reducing production cost and largely increasing work efficiency. In addition, functions of shoveling, digging and breaking and the like can be realized through changing tools according to the usage, and the fork-lift truck large arm rotation device is adaptable to application in stone quarries, mines and municipal projects.

Description

The big arm rotation unit of forklift

Technical field

The utility model belongs to engineering machinery, specifically relates to the improvement structure of the big arm rotation unit of a kind of engineering forklift, can effectively improve the different functions of use of forklift.

Background technology

Existing forklift engineering machinery is a hinged forklift on the support arm of the front end of engineering truck, and to raise the shovel oil cylinder hinged with one.Be mainly used in the loading in the engineering construction, function of use is single, so range of application is limited to.Because working range is little, because of the price of forklift about 20,000 yuan.In the engineering of construction, also can need to excavate, or carry out fragmentation, its price is about 1,000,000 yuan.These all need independent crushing engine and excavator, if dispose complete all engineering machinery, its cost of investment is relatively large like this, also can bring the increase of operating personnel, oil plant, maintenance simultaneously, cause running cost to strengthen.

Summary of the invention

In view of the situation of above-mentioned prior art, the utility model provides a kind of forklift big arm rotation unit, and it has changes different tool usings, can make forklift reach the function and the purpose of a tractor serves several purposes.

For achieving the above object, the utility model provides a kind of forklift big arm rotation unit, and it has hinged one of the support that is provided with and raises the arm oil cylinder on a horizontally hinged extension arm and extension arm on the link; This raises hinged one two arm between the front end of the other end of arm oil cylinder and extension arm; The front end of this two arm is by a hinged bucket cylinder between hinge bar and the hinged seat that has on it; The horizontally hinged oil cylinder that turns between described extension arm and link.Therefore, set extension arm, control by turning to oil cylinder and the rotation that can produce certain angle only need on bucket cylinder and two arms hinged scraper bowl or replacing to dig head and can finish shovel, function such as dig; Simultaneously, can also overcome variation, need the whole problem that moves back and forth number of times, improve operating efficiency, reduced use cost because of working range.

According to scheme of the present utility model, by the situation of practical application, the mentioned oil cylinder that turns to is at least in a side setting of extension arm; Or be symmetricly set in the both sides of extension arm.When selecting one to turn to oil cylinder, turning between oil cylinder and the extension arm that it is hinged is angled, can control rotating horizontally of extension arm like this; If be symmetrical arranged and turn to oil cylinder, the two-way horizontal that can control extension arm back and forth rotates.

According to application characteristic of the present utility model, described two arms and raise between arm oil cylinder and the extension arm being hinged for mobile assembled and disassembled formula.Its effect is to change quartering hammer, is used for the fragmentation of engineering construction.

In a word, the good effect that the utlity model has is: on former forklift, set up rotating extension arm because of having adopted, and two hinged arms, its work plane has been enlarged more than 80%; Simultaneously,, correspondingly reduce the mobile number of times of complete machine, reduced cost of production, improved operating efficiency greatly owing to increased work area; In addition, can be according to purposes, by changing tool device, can realize shovel, dig and function such as fragmentation.Be applicable to the application of stone field, mine, municipal engineering.

Description of drawings

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

Fig. 2 is another embodiment that Fig. 1 changes instrument.

The specific embodiment

Below in conjunction with accompanying drawing embodiment, the utility model will be further described.The accompanying drawing of giving only is to be used for reference and explanation usefulness, is not to be used to limit the utility model scope.

By shown in Figure 1, the big arm rotation unit of forklift comprises a link 1, and the middle part of this link 1 has hinged extension arm 4 of level installation on a pair of twisted seat that is arranged above and below 11; Be positioned at a hinged flexible end that turns to oil cylinder 5 on the twisted seat 10 that the front portion of these extension arm 4 side direction has, and turn to the twisted seat 12 that has on the other end of oil cylinder 5 and the link 1 to be hinged; In the present embodiment, it turns to oil cylinder 5 is to adopt symmetrical manner to be arranged on the both sides of extension arm 4, can realize that the two-way horizontal of extension arm 4 back and forth rotates.Therefore, can rotate within the specific limits by turning to oil cylinder 5 control extension arms 4, enlarged work plane more than 80%, avoided the mobile number of times of forklift according to the difference of work plane.On the support 2 that the rear upper end of described extension arm 4 bodies fixedly installs, raise arm oil cylinder 3 for hinged one; This flexible end of raising arm oil cylinder 3 is hinged one two arm 6 respectively with two pin joints of the hinged end of extension arm 4 front ends.Like this can be by raising arm oil cylinder 3 controls two arms 6 along making reciprocally swinging with the hinged end of extension arm 4.A hinged bucket cylinder 8 on the hinged seat 7 that has on described two arms 6; The cylinder body of the front end of this bucket cylinder 8 is hinged by the front end of a hinge bar 9 and two arms 6.The hinged installation bucket 13 of two pin joints of the flexible end of the bucket cylinder of being given in the present embodiment 8 and two arms, 6 front ends; Promptly can be used for digging operation.

According to above-mentioned application characteristic, it is installed in is provided with one between extension arm 4 side direction and the link 1 and turns to oil cylinder 5.This set-up mode should guarantee to turn between oil cylinder 5 and the extension arm 4 angled, can control extension arm 4 like this for rotating horizontally.

Fig. 2 has provided replacing instrument another embodiment with the different functions of use of Fig. 1.Different is has a multi-functional application characteristic according to above-mentioned, is that the replacing in guaranteeing to use is convenient, and described two arms 6 respectively and the articulated manner of raising between arm oil cylinder 3 and extension arm 4 front ends be mobile assembled and disassembled formula.Promptly, can conveniently remove the integrated member of two arms 6, quartering hammer 14 is installed at the pin joint of the described flexible end of raising arm oil cylinder 3 and the pin joint of extension arm 4 front ends according to different use needs; So just can be used for crushing operation.

According to the above-mentioned application characteristic that has, remove above-mentioned big arm rotation unit, promptly can recover its original forklift function.
