Description

Full hydraulic truck tower crane

1. Technical field

The utility model relates to an engineering hoisting machine, in particular to a new type of machine which organically combines a truck crane and a tower crane—a full hydraulic truck tower crane.

2. Technical background

At present, tower cranes have the characteristics of poor mobility. Even mobile tower cranes need to lay tracks, which is expensive. Moreover, almost all of the tower cranes used in construction are fixed tower cranes. The working space is severely limited, and the installation and erection costs High, accidents are easy to occur during the installation process, and the basic materials are inconvenient to handle when changing the work site, which not only wastes materials but also pollutes the environment. The truck crane has a small range and a low utilization rate. In view of the above reasons, we have proposed the full-hydraulic automobile tower crane technology, which realizes the organic combination of tower cranes and truck cranes with hydraulic technology, and is mainly suitable for multi-storey buildings, stadiums and other sites with large areas and different building heights. In large occasions, it can replace multiple tower cranes and truck cranes, and has the advantages of quick entry into working state, good safety, good fluidity, high equipment utilization rate, and high construction efficiency.

3. Contents of utility model

The purpose of the utility model is to provide a new type of more advanced engineering hoisting machinery - full hydraulic vehicle tower crane.

The utility model provides a full-hydraulic automobile tower crane, which organically combines the good fluidity of the automobile crane with the characteristics of high amplitude utilization and high working speed of the tower crane, and is mainly used for multi-storey buildings, stadiums and other places. In the occasions with large area and low building height, it can replace multiple tower cranes and truck cranes. The whole machine adopts hydraulic erection, remote control operation, and PLC control technology. It has compact structure, small footprint, less impact and safety. , High reliability and so on.

The technical solution is: 1. The foldable tower body is fixed on the slewing platform by means of hinge joints, and the slewing platform is installed on the chassis of the car, and the rotation of the boom of the tower crane is realized through the slewing platform; 2. The foldable tower body is fixed on the hydraulic cylinder. Under the action, the height of the tower body can be changed, that is, the transition between the working state and the horizontal transportation state; 3. The lifting arm and the balance arm with a telescopic mechanism are fixed on a rigid connection mechanism, which is connected to the tower body by hinges , and under the action of the hydraulic cylinder, the lifting arm, the balance arm and the tower body can be kept in a vertical state; 4. The balance arm can be adjusted within a certain range through the change of the telescopic mechanism under the action of the hydraulic pressure, and the balance The weight does not need to be changed; 5. The boom can realize the luffing operation through the change of the telescopic mechanism under the action of hydraulic pressure; 6. The telescopic mechanism adopts a box-shaped structure with multi-stage telescopic arms. 7. The whole machine adopts hydraulic stepless speed regulation transmission mode, remote control operation and PLC control technology.

The utility model organically combines the good fluidity of the truck crane with the characteristics of high amplitude utilization and high working speed of the tower crane, and effectively solves some problems encountered in real life.

5. Specific implementation

With reference to the accompanying drawings of the description, the utility model full hydraulic vehicle tower crane is described in detail below. The 2--swing mechanism of the utility model is that the 9--slewing bearing is fixed on the 1--the automobile chassis through the bolt group, and the upper part is connected with the 10--the tower body base through the bolt group, and the 12--hydraulic motor drive mechanism is used for rotation. Action, 3--the tower body and 10--the base of the tower body are connected through the 11--pin shaft mechanism, as shown in Figure 2. In order to ensure the overall height of the tower crane after folding, the tower body is folded using hydraulic jacking to complete the installation of the tower body, as shown in Figure 3. The specific erection process is: 13--hydraulic cylinder moves first, lifts 7--lifting arm, 5--balance arm, makes 5--end of balance arm contact 1--chassis, and fixes it with 4--balance weight , and then 5--the balance arm is extended, and after the 5--the balance arm is fully stretched out, the 3--the tower body is kept vertical to the 5--the balance arm and 7--the lifting arm. At this time, the tower body has been fully lifted, 14--hydraulic cylinder, 15--hydraulic cylinder have a suitable angle and elongate, 5--the balance arm shrinks a section to lift the balance weight, and finally 14--hydraulic cylinder, 15- -Under the action of the hydraulic cylinder, the 3--tower body is vertical to the 1--chassis, and the installation process is completed. The 3-tower body, 5-balance arm, and 7-lifting arm all adopt a box-type multi-stage telescopic boom structure, and the multi-section telescopic booms are sequentially packaged together, and the telescopic function is realized through the oil cylinder and the wire rope row. 5--The length of the balance arm can be adjusted automatically with the change of the lifting moment to meet the requirements of the working state for the balance moment.

The utility model organically combines the good fluidity of the truck crane with the characteristics of high amplitude utilization and high working speed of the tower crane, adopts hydraulic erection, remote control operation, and PLC control technology, and has the advantages of compact mechanism, small floor space and less impact , High security and reliability. Therefore, it has good promotion value.

Except for the technical features described in the specification, all are general technologies.
