The full hydraulic automobile tower type crane adopts an automobile chassis with power as basis, hydraulic supporting legs are taken as supports, tower body mechanisms which can be folded and extended are fixed on the automobile chassis through a rotary platform, and a cargo boom and a balance bob adopt hydraulic telescopic mechanisms to realize amplitude operations. The whole machine adopts hydraulic erection, remote control operations and the PLC control technique, the full hydraulic automobile tower type crane is characterized in that the mechanism is compact, the crane is characterized in that the occupied area is small, the shock is little, the safety and the reliability are high, and the like. Thereby, the full hydraulic automobile tower type crane has good extending and using value.

Description

Full hydraulic vehicle tower crane

1, technical field

The utility model relates to a kind of crane tool, specifically novel mechanical---the full hydraulic vehicle tower crane that car hosit and tower crane are organically combined.

2, technical background

At present, there are the characteristics of flowing power difference in tower crane, even movably tower crane also needs to lay track, the expense height, furthermore what use in the construction now almost all is fixed type tower machine, working space is seriously limited, the expense height is set up in installation, and easy mis-use breakdown in the installation process is when changing the work-yard, basic material inconvenience is handled, and has not only wasted material but also polluted environment.The car hosit amplitude is little and degree of utilization is little.In view of above reason, we have proposed the full hydraulic vehicle tower crane technology, this technology has realized the combination of tower crane and car hosit and hydraulic technique, the occasions that site area is big, depth of building is little such as main oriented multilayer groups of building, stadiums, alternative many tower cranes and car hosit work, have that the mode of operation of entering is rapid, safety good, good fluidity, capacity utilization rate height, high efficient construction.

3, utility model content

The purpose of this utility model provides a kind of advanced more novel crane tool---full hydraulic vehicle tower crane.

The utility model provides a kind of full hydraulic vehicle tower crane, flowing power that it is good with car hosit and tower crane amplitude degree of utilization height, the characteristics that work speed is high combine, the occasions that site area is big, depth of building is little such as main oriented multilayer groups of building, stadiums, alternative many tower cranes and car hosit work, complete machine adopts that hydraulic pressure sets up, remote manipulation, PLC control technology, have mechanism's compactness, floor area is little, impact is few, characteristics such as safety, reliability height.

Its technical scheme is: 1, collapsible body of the tower is fixed on the turn table by articulated manner, and turn table is installed on the car chassis, realizes the revolution of tower machine crane arm by turn table; 2, collapsible body of the tower can be realized the body of the tower height change under the effect of hydraulic actuating cylinder, promptly changes between mode of operation and horizontal travelling position; 3, have the crane arm of telescoping mechanism and equilibrium arm and be fixed on one and be rigidly connected in the mechanism, this bindiny mechanism is connected by articulated manner with body of the tower, and can make crane arm, equilibrium arm and body of the tower keep plumbness under the hydraulic actuating cylinder effect; 4, equilibrium arm can the variation by telescoping mechanism realize that balancing torque is adjustable within the specific limits under action of hydraulic force, and counterbalanced weight need not to change; 5, crane arm can the variation by telescoping mechanism be realized the luffing operation under action of hydraulic force; 6, telescoping mechanism adopts the box-structure with multi-stage expansion arm, and it is arranged and realize bigger Telescopic by amplifying Strok mechanism and steel rope under the effect of telescopic oil cylinder; 7, complete machine adopts hydraulic stepless speed regulating type of drive, remote manipulation, PLC control technology.

Flowing power that the utility model is good with car hosit and tower crane amplitude degree of utilization height, the characteristics that work speed is high combine, and efficiently solve some difficult problems that run in the actual life.Accompanying drawing is a full hydraulic vehicle tower crane structural principle scheme drawing

5. the specific embodiment

With reference to Figure of description the utility model full hydraulic vehicle tower crane is done following detailed description the in detail.2--swing type mechanism of the present utility model be the 9--pivoting support by bolt group stuck-at---on the car chassis, top is connected with 10--body of the tower base by the bolt group, adopt 12--fluid motor-driven mechanism to turn round action, be connected by the 11--pin framework between 3--body of the tower and the 10--body of the tower base, as shown in Figure 2.For guaranteeing the whole height after the tower machine folds, the folding employing of body of the tower hydraulic lifting mode is finished the erection work of body of the tower, as shown in Figure 3.Concrete erection process is: the 13--hydraulic actuating cylinder at first moves, with 7--crane arm, 5--equilibrium arm jack-up, make the terminal contact of 5--equilibrium arm 1--chassis, and fix with the 4--counterbalanced weight, 5--equilibrium arm elongation then, after treating that the 5--equilibrium arm all stretches out, the 3--body of the tower keeps vertical with 5--equilibrium arm, 7--crane arm.This moment, body of the tower fully lifted, 14--hydraulic actuating cylinder, 15--hydraulic actuating cylinder have suitable angle and elongation, the 5--equilibrium arm shrinks one section to mention counterbalanced weight, and the 3--body of the tower is vertical with the 1--chassis under the effect of 14--hydraulic actuating cylinder, 15--hydraulic actuating cylinder at last, finishes installation process.3--body of the tower and 5--equilibrium arm, 7--crane arm all adopt box multi-stage expansion arm configuration, and multi-stage telescopic arms is sleeved on together in proper order, add steel rope by oil cylinder and arrange and realize Telescopic.The length of 5--equilibrium arm can change automatic compensation along with hoisting moment, to adapt to the requirement of mode of operation to balancing torque.

The flowability that the utility model is good with autocrane and derrick crane amplitude utilization rate height, worker Make fast characteristics and combine, adopt that hydraulic pressure sets up, straighforward operation, PLC control skill Art has mechanism's compactness, floor space is little, impact is few, security, reliability high. Thereby, have good value for applications.

Except the described technical characterictic of specification, be current techique.
