Embodiment Construction

[0015] A quick-loading tower crane, such as figure 1 As shown, it includes hook group 1, luffing trolley 2, luffing mechanism 4, tower body 8, 9, tower arms 3, 5, counterweight 14, electric control cabinet 11, hoisting winch system 13, slewing mechanism 17 , Cable reel 16. The tower body includes an upper tower body 8 and a lower tower body 9. The upper and lower tower bodies are connected by bayonet joints to form a scalable structure. The upper tower body can be compressed to the inside of the lower tower body, and the upper and lower tower bodies are connected by a tail cable system 7 Complete the compression and tension of the tower body. The tower arm includes a front tower arm 3 and a rear tower arm 5. The front and rear tower arms are connected by a pin shaft, and the left and right folding of the tower arm is realized through the arm rope system; the rear end of the rear tower arm 5 is hinged with the tailstock 6, and the tailstock 6 The end point of the tail cable s...

Abstract

The invention belongs to the technical field of crane manufacturing and relates to a quick-assembly tower crane. The quick-assembly tower crane comprises an upper tower body and a lower tower body, wherein the upper tower body can be compressed into the lower tower body, so that a telescopic structure is formed; the tower bodies are compressed or stretched through a tail inhaul cable system. Tower arms include a front tower arm and a rear tower arm which are connected through a pin shaft, and the tower arms are folded leftwards and rightwards through an arm unfolding rope. The first section at the bottom of each tower body is arranged to be of an isosceles right triangle structure, and the bottom of the lower tower body is of a foldable structure in a pin shaft connection mode. Meanwhile, two erection rods are arranged to maintain the overall stability of the tower crane. The tower crane is assembled quickly through the tail inhaul cable system, a raising and winching system, a rotation system and the arm unfolding rope system. The quick-assembly tower crane has the advantages of being quick in assembling, safe in operation, low in cost, convenient to use and the like.

Description

technical field [0001] The invention belongs to the technical field of crane manufacturing, and in particular relates to a quick-install tower crane. Background technique [0002] Tower crane, also known as tower crane, is the abbreviation of tower crane, which is widely used in a kind of lifting equipment in construction. It is equipped with tower crane foundation, tower body, jacking, slewing, hoisting, balance arm, lifting arm, lifting trolley, tower top, driver's cab, luffing and other parts. The installation of the tower crane on the ground requires the basic part to fix the structure such as the tower body. The tower body is the body of the tower body and is also a raised part. The jacking part is the device required to raise the tower crane. The slewing maintains the horizontal rotation of the upper body of the tower crane. The hoisting mechanism is used to lift heavy objects. The balance arm frame keeps the torque balance of the tower crane. The force-bearing part ...
