AI Technical Summary

Problems solved by technology

The balance weight is quite considerable. Light tower cranes generally require at least 3 to 4 tons, and heavy tower cranes require nearly 30 tons. At the same time, the bottom of the tower crane bears the entire weight of the fuselage, so there are always potential safety hazards at the bottom of the tower crane, and it affects operators and nearby workers. life and health of residents
Especially in the construction of tower cranes on complex ground such as mountains and hills, the factors considering the strength of the bottom are more complicated, and there is currently no device to solve this problem

Embodiment 1

[0021] A universal support device at the bottom of a tower crane, which consists of: a bottom telescopic steel plate 2, the bottom telescopic steel plate is connected with a telescopic base 4, the telescopic base is connected with a strong bolt 10, and the strong bolt is connected with The lower end 5 of the telescopic rod is connected, and the top end of the telescopic rod is connected with the top telescopic steel plate 8 .

Embodiment 2

[0023] According to the universal support device at the bottom of a tower crane described in Example 1, a locking device 1 is installed in the middle of the telescopic steel plate at the bottom, a locking device 3 is arranged in the middle of the telescopic base, and a powerful force is installed in the telescopic rod. Locking device 6 and stud bolt 7, locking device 9 is housed in the middle of described top telescopic steel plate.

Embodiment 3

[0025] According to the installation method of a kind of tower crane bottom universal support device described in Example 1, comprises the following steps:

[0026] Step 1: The worker installs the bottom retractable steel plate on the bottom of the tower crane and locks it with a locking device;

[0027] Step 2: Install the telescopic base according to the actual terrain, adjust the length, and lock it with the locking device;

[0028] Step 3: Connect the telescopic base to the telescopic rod with strong bolts;

[0029] Step 4: Install the top retractable steel plate at a suitable height according to the actual situation, and lock it with a locking device;

Abstract

A tower crane bottom all-purpose supporting device is provided. The weight of a light tower crane is 3-4 t generally, the weight of a heavy type tower crane is near to 30 t, and a tower crane bottom bears all weight including the machine body, and therefore the bottom has safety ricks all the time, and life health of operators and nearby residents are influenced. Bottom strength considering factors are more complex especially for construction of a tower crane on complex ground surfaces, such as mountains and hills, and no device at present can solve the problem. The supporting device comprises bottom telescoping steel plates (2), wherein the bottom telescoping steel plates are connected to a telescope pedestal (4), the telescope pedestal is connected to high strength bolts (10), the high strength bolts are connected to lower ends (5) of telescoping bars, and the tops of the telescope bars are connected to top telescoping steel plates (8). The supporting device is used for strengthening tower crane bottom strength.

Description

1. Technical field [0001] The invention relates to a universal support device at the bottom of a tower crane. 2. Background technology [0002] As we all know, the tower crane is the most commonly used lifting equipment on the construction site. The upper slewing tower crane of the tower crane needs to be equipped with a balance weight. Its function is to support the balance weight. the balance moment. The amount of balance weight is inversely proportional to the length of the balance arm, and there is a certain proportional relationship between the length of the balance arm and the length of the boom. The balance weight is quite considerable. Light tower cranes generally require at least 3 to 4 tons, and heavy tower cranes require nearly 30 tons. At the same time, the bottom of the tower crane bears the entire weight of the fuselage, so there are always potential safety hazards at the bottom of the tower crane, and it affects operators and nearby workers. residents' healt...
