Description

Technical Field

[0001] The utility model belongs to the technical field of tower crane adjustment, and particularly relates to a tower crane foundation verticality adjustment device. Background Technique

[0002] As an indispensable heavy equipment on construction sites, tower cranes are widely used in high-rise buildings, bridges, power plants, ports and other large infrastructure projects. The main function of a tower crane is to lift heavy objects through its high tower structure and long arm, realizing large-range horizontal and vertical transportation within a narrow construction site. Due to its unique structure and load-bearing capacity, the role of tower cranes in construction is particularly important, directly related to the construction progress and safety.

[0003] The stability of a tower crane is the key to its safe operation, and the design and construction quality of the foundation are one of the core factors determining its stability. The foundation of a tower crane usually consists of a concrete cushion cap and embedded sections. The embedded sections are connected to the standard sections of the tower crane through bolts, supporting the entire tower body. Therefore, the flatness and verticality of the foundation directly affect the overall verticality and stability of the tower crane. If there are deviations during the construction process of the tower crane foundation, such as improper positions of the embedded sections or inconsistent elevations of the legs, it may lead to tower body inclination, uneven stress, and even cause the overturning accident of the tower crane.

[0004] Especially in the construction of high-rise buildings, tower cranes are usually exposed to wind loads and other complex environmental conditions, and any minor foundation deviation will be amplified into a huge safety hazard. Therefore, ensuring the verticality of the tower crane foundation is an important prerequisite for ensuring the safe operation of the tower crane. However, during the actual construction process, if the embedded sections lack necessary fixing measures, displacement or inclination may occur during the concrete pouring process of the cushion cap, resulting in large differences in the surface elevations of the four leg bottom plates of the embedded sections. If not adjusted in time, these deviations will cause the installation verticality of the tower crane standard sections to exceed the specification requirements, seriously affecting the safety and service life of the tower crane. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tower crane foundation verticality adjustment device to solve the problem that the foundation cushion cap may displace or incline during the concrete pouring process, resulting in large differences in the four legs of the embedded section.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a tower crane foundation verticality adjustment device, including an embedded section, a standard section is arranged at the top of the embedded section, an adjustment component is arranged between the standard section and the embedded section, and the adjustment component includes inclined shims, and the inclined shims are fixedly installed between the standard section and the embedded section.

[0007] Preferably, a column base plate is fixedly installed on the outer wall of the lower side of the standard section, a fixed base plate is fixedly installed on the outer wall of the upper side of the embedded section, and the bevel washer is located between the column base plate and the fixed base plate.

[0008] Preferably, the adjusting assembly further includes a bolt and a hemispherical nut. The bolt passes through the column base plate and the fixed base plate, and one end of the bolt is threadedly connected to the hemispherical nut.

[0009] Preferably, a hemispherical notch is provided on the fixed base plate, and the hemispherical nut is rotatably installed in the hemispherical notch.

[0010] Preferably, a foundation bearing platform is further included, and the embedded section is fixedly installed on the foundation bearing platform.

[0011] The technical effects and advantages of the present utility model: When using concrete to pour and form a foundation bearing platform, displacement or inclination may occur during the fixation of the embedded section, resulting in inconsistent heights when fixing the standard section. Different specifications of bevel washers are used and placed between the standard section and the embedded section to correct the angular deviation of the standard section. Then, through the design of the hemispherical bolt and the fixed base plate, the hemispherical bolt can adapt to adjustments at different angles. Through the effective contact between the hemispherical bolt and the fixed base plate, the perpendicularity of the standard section is ultimately ensured to meet the safety requirements.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] The present utility model provides as Figures 1-3A tower crane foundation verticality adjustment device shown in the figure includes a buried section 2. A standard section 1 is arranged at the top of the buried section 2. An adjustment assembly is arranged between the standard section 1 and the buried section 2. The adjustment assembly includes an inclined shim 6, and the inclined shim 6 is fixedly installed between the standard section 1 and the buried section 2. It also includes a foundation cap 3, and the buried section 2 is fixedly installed on the foundation cap 3. The buried section 2 is fixed by concrete pouring, and the concrete accumulates to form the foundation cap 3. During the fixing process of the buried section 2, certain displacement or inclination may occur, resulting in inconsistent heights of the standard section 1 during fixing. In this case, inclined shims 6 of different specifications are respectively placed between the standard section 1 and the buried section 2 to balance the four fixing bottom plates 7 of the buried section 2, forming an installation surface parallel to the ground to correct the angular deviation that occurs during the installation of the standard section 1. Then, through the cooperation of the hemispherical bolt 4 and the hemispherical notch arranged on the fixing bottom plate 7, the hemispherical bolt 4 can adapt to adjustments of different angles, enabling effective contact between the hemispherical bolt 4 and the fixing bottom plate 7, and finally ensuring that the verticality of the standard section 1 after installation meets the safety requirements.

[0018] Specifically, a column bottom plate 5 is fixedly installed on the outer wall of the lower side of the standard section 1, and a fixing bottom plate 7 is fixedly installed on the outer wall of the upper side of the buried section 2. The inclined shim 6 is located between the column bottom plate 5 and the fixing bottom plate 7. The adjustment assembly also includes a bolt 4 and a hemispherical nut 8. The bolt 4 passes through the column bottom plate 5 and the fixing bottom plate 7, and one end of it is threadedly connected to the hemispherical nut 8. A hemispherical notch is arranged on the fixing bottom plate 7, and the hemispherical nut 8 is rotatably installed in the hemispherical notch. Among them, the inclined shim 6 has various inclination specifications and is respectively applied between the buried section 2 and the standard section 1 with different inclination angles. Figure 2 、 3 As shown in the figure, when fixing the standard section 1, the offset angle of the buried section 2 can be adjusted by placing inclined shims 6 of different inclination specifications to make up for the inclination of the buried section 2. The corresponding inclined shim 6 is placed between the column bottom plate 5 arranged at the lower end of the standard section 1 and the fixing bottom plate 7 arranged at the upper end of the buried section 2, so that the standard section 1 and the buried section 2 remain in a state of being naturally perpendicular to the ground after being fixed. After determining the inclined shim, the bolt 4 can pass through the column bottom plate 5 and the fixing bottom plate 7, and the hemispherical nut 8 is installed in the hemispherical notch to threadedly connect the bolt 4 to achieve fixation. In this way, by adjusting the different angles of the hemispherical nut 8 to cooperate with the inclination of the bolt 4, and no matter what the inclination angle is, the hemispherical nut 8 is connected to the fixing bottom plate 7 to increase the stability effect and ensure the subsequent use of the standard section 1.
