Abstract
A telescopic digger belongs to the digger field, which comprises a moving body which is assembly arranged outside a fixed body and a bucket rod hydraulic cylinder which is fixedly arranged on the upper end of a boom body, is characterized in that first, the forearm of the boom body comprises the hollow moving body and fixed body, the fixed body and the moving body assembly arranged outside the fixed body are connected to be one body through the hydraulic cylinder and the cylinder body of the hydraulic cylinder and a moving rod are fixedly arranged on the fixed body and moving body respectively, second, the bucket rod hydraulic cylinder is fixedly arranged on the upper end of the boom body. The utility model does the improvements above to the current technical product, not only can adjust the flexibility of the telescopic arm at any time to adjust the digging depth, but also has simple structure, easy operation and long-range extension and application.
Description
Technical field
The utility model belongs to the excavator field, specifically is a kind of telescopic arm excavator.
Background technology
Must obligato plant equipment when excavator is construction such as current various building, road and bridge, and, produced huge social and economic benefit because the appearance of these mechanized equipments has improved speed of application greatly.But because the difference of construction plant, operating personnel's controlling in the process as excavator in reality, the telescopic arm of the excavator of discovery prior art is subjected to the influence of its inherent structure, ubiquity swing arm or dipper retractility limited bigger, cause its excavation depth to be affected accordingly, be difficult to adjust telescopic arm accordingly according to the concrete condition of job site.
The utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides a kind of prior art is carried out improvedly can adjusting the telescopic arm retractility at any time, suitably adjusts excavation depth, and simple in structure, the telescopic arm excavator of easy operating.
For achieving the above object, the utility model is achieved through the following technical solutions:
Be a kind of telescopic arm excavator, it is external surely to comprise that kinetoplast is sleeved on, and swing arm body upper end fixed installation dipper hydraulic jack is characterized in that:
1) forearm of swing arm body is by the kinetoplast of hollow and decide body two parts and constitute, and kinetoplast is sleeved on external surely, and both combine as a whole by hydraulic jack, the cylinder body of hydraulic jack and move bar and be fixedly installed on respectively and decide on body and the kinetoplast.
2) swing arm body upper end fixed installation dipper hydraulic jack.
According to excavator model difference, on dipper, also can adopt above-mentioned identical scheme to improve according to actual conditions.
For guaranteeing that kinetoplast has enough extendable rooms, kinetoplast and the hydraulic jack of deciding to be provided with between the body can be multi-joint telescoping formula oil cylinder.
The utility model not only can be adjusted the telescopic arm retractility after prior art products is as above improved at any time, suitably adjusts excavation depth, and simple in structure, and easy operating is suitable for applying on a large scale.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model embodiment mounting structure schematic diagram.
Among the figure: 1 dipper; 2 dipper hydraulic jacks; 3 kinetoplasts; 4 hydraulic jacks; 5 cylinder bodies; 6 decide body.
The specific embodiment
As shown in Figure 1, the utility model comprises that the kinetoplast 3 that links with dipper 1 is sleeved on to be decided outside the body 6, kinetoplast 3 upper ends are provided with dipper hydraulic jack 2, it is characterized in that swing arm body forearm is by the kinetoplast 3 of hollow and decide body 6 two parts and constitute, kinetoplast 3 is sleeved on to be decided outside the body 6, both combine as a whole by hydraulic jack 4, and the cylinder body of hydraulic jack 4 and moving bar are fixedly installed on respectively to be decided on body and the kinetoplast.Kinetoplast 3 upper ends fixed installation dipper hydraulic jack 2.The actuation means of hydraulic jack 4 can link with the master control device of equipment, so that control easily.According to the difference of excavator model, on dipper 1, also can adopt above-mentioned identical scheme to improve according to actual conditions.
Like this, when excacation normally, hydraulic jack 4 is in contraction state, and equipment is operated routinely and got final product.When needs are deepened excavation depth, can hydraulic jack 4 be started working by controlling the control device of hydraulic jack 4, this moment, the hydraulic pressure of hydraulic jack 4 moved the kinetoplast 3 that masthead moves swing arm body forearm, deepened excavation depth with this.After excacation finishes, control the above-mentioned kinetoplast 3 of hydraulic jack 4 drives and reset, in order to reusing.
For guaranteeing that kinetoplast 3 has enough extendable rooms, kinetoplast 3 and the hydraulic jack of deciding to be provided with between the body 64 can be multi-joint telescoping formula oil cylinder.
After the utility model as above improves prior art products, not only can adjust the retractility of telescopic arm at any time, suitably adjust excavation depth, and simple in structure, and easy operating is suitable for applying on a large scale.
Claims (2)
1, a kind of telescopic arm excavator comprises that the kinetoplast that links with dipper is sleeved on dipper hydraulic jack external surely and that swing arm body upper end is provided with, is characterized in that
1) forearm of swing arm body is by the kinetoplast of hollow and decide body two parts and constitute, and kinetoplast is sleeved on external surely, and both combine as a whole by hydraulic jack, the cylinder body of hydraulic jack and move bar and be fixedly installed on respectively and decide on body and the kinetoplast;
2) kinetoplast upper end fixed installation dipper hydraulic jack.
2, telescopic arm excavator according to claim 1, it is external surely to it is characterized in that kinetoplast is sleeved on.
