The base of the existing tower crane does not have an adjusting function, when the crane needs to be modified and hoisted to bear the weight, the base needs to be replaced, the base is replaced, time and labor are wasted, and the base is very troublesome, so that the problem is solved by designing an adjustable base for the tower crane urgently.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a tower crane is with adjustable base to thereby solve current tower crane base because there is not regulatory function to cause the problem that wastes time and energy, very trouble when changing the base.

In order to solve the technical problem, the utility model provides an adjustable base for tower crane, which comprises a base, wherein an organism is fixed at the top end of the base, the bottom end of the base is connected with a support frame through two first telescopic rods and is fixed with two straight rods, the support frame and the top end are also provided with two notches, two bearings are fixed on the inner bottom surface of the base, the bottom ends of the two straight rods respectively pass through the two notches and are respectively provided with a threaded groove, the two bearings are respectively connected with a screw rod, a first gear is fixed on each screw rod, and the other end of each screw rod is positioned in the threaded groove and is in threaded connection with the threaded groove;

the top surface in the supporting frame is fixed with driving motor, and its output is connected with through the pivot with two first gear all meshes driven second gear.

Optionally, the base is connected with the support frame through a second telescopic rod.

Optionally, sliding grooves are formed in the two sides of the supporting frame, U-shaped plates are fixed to the two sides of the base, and sliding blocks located in the sliding grooves are further fixed to the side faces of the U-shaped plates.

The utility model provides an in the adjustable base for tower crane, including the base, the organism is fixed on the base top, and the bottom is connected with the carriage and is fixed with two straight-bars through two first telescopic links, the carriage with the top still open two notches, the inside bottom surface is fixed with two bearings, two straight-bar bottoms pass two the notches respectively and all open the screw thread groove, all be connected with the screw rod on two the bearings, all be fixed with first gear on two the screw rods and the other end is located in the screw thread groove and is connected with its screw thread; a driving motor is fixed on the top surface inside the supporting frame, and the output end of the driving motor is connected with a second gear which is in meshing transmission with the two first gears through a rotating shaft; by using the base, the base can be freely adjusted, when the crane needs to be modified and hoisting bearing is increased, the base does not need to be replaced, and the working efficiency is ensured.

Drawings

Fig. 1 is the utility model provides an adjustable base structure sketch map for tower crane.

Detailed Description

The following provides a further detailed description of the adjustable base for a tower crane according to the present invention with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

Example one

The utility model provides an adjustable base for tower crane, its structure is shown in figure 1, including base 1, organism 2 is fixed on the top of base 1, the bottom is connected with carriage 3 and is fixed with two straight-bars 10 through two first telescopic links 5, carriage 3 and the top still open two notches 4, the inside bottom surface is fixed with two bearings 7, two straight-bars 10 bottom pass two notches 4 respectively and all open threaded groove 11, all be connected with screw rod 8 on two bearings 7, all be fixed with first gear 9 on two screw rods 8 and the other end is located in threaded groove 11 and is connected with its screw thread; the inside top surface of carriage 3 is fixed with driving motor 12, its output be connected with through pivot 13 with two first gear 9 all meshes driven second gear 14, through driving motor 12 output drives second gear 14 and two first gear 9 meshes the transmission, makes two screw rod 8 rotates and drives straight-bar 10 drives base 1 is adjusted. By using the adjustable base for the tower crane, when the crane needs to be modified and hoisting bearing is increased, the base does not need to be replaced, and the working efficiency of the crane is ensured.

The base 1 and the supporting frame 3 are also connected through a second telescopic rod 15 to further support the base 1; both sides of the supporting frame 3 are provided with sliding grooves 16, both sides of the base 1 are fixed with U-shaped plates 17, and the side surfaces of the U-shaped plates 17 are also fixed with sliding blocks 18 positioned in the sliding grooves 16, so that the base 1 is supported more stably.
