Embodiment 1

[0042] refer to Figure 1 to Figure 7 As shown, the leveling device used for tower crane tilting after installation includes an upper chassis 1 connected to the tower body of the crane and a lower chassis 6 connected to the embedded foundation section, the upper chassis 1 and the lower An adjustment mechanism is arranged between the chassis 6, and the adjustment mechanism includes a threaded sleeve 7 arranged at the lower end of the upper chassis 1, an adjustment rod 4 arranged on a vertical horizontal plane, a locking member 5 arranged at the upper end of the lower chassis 6 and a matching lock The fixing part 8 of the tightening part 5, the fixing part 8 is embedded in the locking part 5, one end of the adjusting rod 4 is set through the lower end of the threaded sleeve 7, and the other end is connected with the fixing part 8, and the adjacent At least one adjustable strut 2 is arranged between the adjustment mechanisms.

[0043] The fixing member 8 is a sphere with an open...

Embodiment 2

[0059] The adjustment mechanisms are respectively arranged at the four corner fulcrums between the upper chassis 1 and the lower chassis 6, and the adjustable struts 2 are arranged in parallel in pairs.

[0060] The two ends of the adjustable struts 2 are connected to the upper chassis 1 and the lower chassis 6 through rotatable parts, and the two adjustable struts 2 parallel to each other are arranged alternately.

Embodiment 3

[0062] The inner wall of the lower end of the upper pressing plate 10 is provided with a groove 13 , and the lower pressing plate 9 is provided with a through groove 14 .

[0063] By adopting the above technical scheme, the leveling base frame is installed behind the bottom feet, and the structure is as follows: figure 1 As shown, this state ensures that the pressure plate compresses the lower sphere of the adjusting rod 4 by pre-tightening the high-strength bolts. According to the load on the whole tower crane, design reasonable adjustment rod 4 thread, material and sphere diameter, so that the adjustment rod 4 can meet the different requirements in the normal operation of the tower crane and the tilt adjustment process; after the tower crane tilts, the tower crane should be leveled , to ensure that the four adjustment rods 4 are under pressure. The tower crane balance refers to a means of balancing the weight of the front and rear arms to reduce the bending moment of the tow...

Abstract

The invention discloses a leveling device and method for tilt of a tower body after installation of a tower-type crane. According to the technical scheme, the leveling device is characterized by comprising an upper underframe connected to the tower body of the crane and a lower underframe connected to a pre-buried foundation section, adjusting mechanisms are arranged between the upper underframe and the lower underframe, each adjusting mechanism comprises a thread sleeve arranged at the lower end of the upper underframe, an adjusting rod perpendicular to the horizontal plane, a locking memberarranged at the upper end of the lower underframe and a fixing member matched with the locking member, each fixing member is embedded into the corresponding locking member, one end of each adjusting rod is arranged at the lower end of the corresponding thread sleeve in a penetrating mode, the other end of each adjusting rod is connected with the corresponding fixing member, and at least one adjustable strut is arranged between the every two adjacent adjusting mechanisms. According to the leveling device, the tower-type crane does not need to be dismantled and re-installed, the construction process is reasonably reduced, the safety in the adjustment process is also improved, the safety coefficient of an operator is increased, the treatment period is effectively shortened, the construction cost of a project is significantly reduced, and the project progress can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of hoisting and transportation, in particular to a leveling device and method for tilting the tower body of a tower crane after installation. Background technique [0002] With the rapid development of the economy, the requirements for the installation of equipment in the construction period are becoming more and more urgent. For the installation of various components of the tower crane, it is not only necessary to ensure the safety of the operation, but also requires high efficiency of work. For the installation of traditional tower cranes, the base section at the bottom of the tower crane is directly embedded in the cast-in-place concrete foundation structure, and the verticality between the tower body and the horizontal plane cannot be changed after installation. As the construction environment is becoming more and more complex, it is inevitable to encounter foundation settlement or the foundation section...
