Problems solved by technology

[0002] At present, most of the materials used in high-rise buildings are transported by tower cranes. In order to send building materials to various points of the building, it is necessary to design a longer tower beam. Because the tower beam is too long, a certain eccentric force will be generated when lifting materials. In order to ensure the stability of the tower crane, there must be a firm tower base. At present, a pit is dug on the side of the building to be built and poured with concrete and steel bars, and then the tower crane is fixed. This method can be used But it caused great waste and left a big trouble in the later stage. A concrete tower needs more than 100 tons of cement, several tons of steel bars, and a large amount of labor. In this way, a concrete tower needs to waste RMB 40 -500,000 yuan, if there are other constructions underground in the building, the concrete tower crane seat will have to be removed, and the tower crane will still be the same when it moves to the next operation point, so it will waste hundreds of tons for each building How much resources will be wasted in the world with cement and several tons of steel bars

Embodiment 1

[0029] Embodiment 1, first at the desired position of the mobile tower, dig an earth pit according to the required size, put the bottom beam 20 into the earth pit after assembling (such as image 3 As shown) to lay the plank, first take two partitions 5, insert them into the grooves 16 on the corner assembly 15 respectively and place them vertically on one of the four corners of the bottom beam 20, and pass the bolt 3 through the corner assembly 15 Tighten the screw holes 18 and nuts 21 of the Ding assembly 14 and insert them with the partition plate 5, and then use the bolt 3 to pass through the screw holes 18 and nuts 21 in the Ding assembly 14 and tighten them firmly, so that the bottom beam 20 After the surroundings are installed, take the cross assembly 13 and the partition 5, insert one side of the partition 5 into the groove 16 of the installed small assembly 14, and insert the bolt 3 through the cross assembly 13 after firmly inserting the cross assembly 13 on one side....

Embodiment 2

[0030] Embodiment 2, with the center of the mobile tower hanger as the point, 8 tension beams 2 are set respectively, 4 of which are respectively connected to the screw rods 3 on the corner assemblies 15 at the four corners of the box body 4 and screwed firmly, and straddle them The screw 3 on the cross assembly 13 is screwed firmly, and the other four are vertically screwed to the screw 3 on the D assembly 14 in four directions, and the screw 3 on the cross assembly 13 that it crosses is screwed firmly. At this time, the beam 2 form a "meter" font on casing 4. The assembled cross assembly, the small assembly 14 and the corner assembly 15 are sealed with dustproof cloth 19 to prevent soil from entering (preventing from being bitten when dismantling). At this time, the soil taken out in the pit before is backfilled to each square three-dimensional box In the body 4, (also each casing can be sealed and filled with water with anti-seepage material), then after the stand 1 is fixe...

Embodiment 3

[0031] Embodiment three, when the tower crane needs to be moved to other construction sites after the completion of the project, the tower crane and the tower hanger frame 6 are first dismantled, and then after the stand 1 and the tension beams 2 in each direction are removed, all the bolts 3 are unscrewed with a hoist ( such as chain guides and cranes), firstly lift out the corner components 15 and small components 14 around the mobile tower crane seat, and then lift out the cross components 13 one by one. Each assembly), at last dividing plate 5 is proposed one by one, now only bottom beam 20 is left in the ground, as what inject in each three-dimensional casing 4 is that water is as mentioned above when dismantling, and last bottom beam also can take out.

[0032] The combined design of the present invention is conducive to installation and disassembly, and is conducive to transportation and storage. It occupies a small space. One tower crane only needs to be equipped with a...

Abstract

A mobile crane base comprising a frame base, separator plates, box bodies, bolts, a bottom beam, a pull beam, a crane frame, intersection components, T-shaped components, and corner components. The separator plates are assembled with the intersection components, the T-shaped components, and the corner components into multiple square three-dimensional box bodies that are fixedly mounted onto the bottom beam with the bolts. The pull beam is fixedly mounted onto the box bodies. The frame base is fixedly mounted onto the pull beam. The crane frame is fixedly mounted on the frame base.

Description

technical field [0001] The present invention is in the field of design and construction, and in particular relates to a mobile tower crane that can be disassembled and assembled for continuous use without waste of construction tools. Background technique [0002] At present, most of the materials used in high-rise buildings are transported by tower cranes. In order to send building materials to various points of the building, it is necessary to design a longer tower beam. Because the tower beam is too long, a certain eccentric force will be generated when lifting materials. In order to ensure the stability of the tower crane, there must be a firm tower base.
