Embodiment 1

[0026] see Figure 1-5 , a tower crane with an anti-climbing function, comprising a crane main body 27, several pairs of vertical rods 1 are arranged around the crane main body 27, and two sliding sleeves 2 distributed up and down are slidably installed on the vertical rods 1 A scissor brace 3 is hinged between the sliding sleeves 2 of adjacent vertical rods 1, the scissor brace 3 is provided with a traction assembly, the vertical rod 1 is fixed with a fixed frame 26, and the fixed frame 26 is provided with a The driving mechanism of the assembly, the bottom of the vertical rod 1 is rotatably equipped with a traveling wheel 22, the traveling wheel 22 is connected to the driving mechanism through a transmission mechanism, and the traveling wheel 22 is provided with an anti-skid mechanism including several post 18, so The traveling wheel 22 is provided with an adjustment mechanism that is in transmission connection with the post 18 .

[0027] The device can adjust the extension...

Embodiment 2

[0032] On the basis of Embodiment 1, in addition, the transmission mechanism of this device includes a hanger 11 vertically fixed on the fixed frame 26, and a bevel gear II13 is installed on the hanger 11, and the transmission between the bevel gear II13 and the road wheel 22 A pulley mechanism 14 is connected, and the transmission mechanism also includes a bevel gear I12 meshed with the bevel gear II13, and the bevel gear I12 is coaxially fixedly connected with the lower end of the worm 9.

[0033] When the worm 9 is driven to rotate by the motor 7, the worm 9 drives the bevel gear I12 to rotate, and the bevel gear I12 drives the bevel gear II13 meshed with it to rotate, and the bevel gear II13 can drive the running wheel 22 to rotate through the pulley mechanism 14, thereby realizing the running wheel 22 The effect of promoting the stretching of the scissors brace 3 realizes that the traveling wheel 22 drives the vertical rod 1 to move flexibly.

[0034] In order to improve ...

Abstract

The invention discloses a tower crane with an anti-climbing function, and relates to the technical field of cranes. The tower crane comprises a crane main body, a plurality of pairs of vertical rods are arranged around the crane main body, a driving mechanism for driving a traction assembly is arranged on a fixing frame, walking wheels are rotatably mounted at the bottoms of the vertical rods, each walking wheel is provided with an anti-skid mechanism comprising a plurality of inserting columns, and each walking wheel is provided with adjusting mechanisms in transmission connection with the inserting columns. According to the tower crane, the driving mechanism is used for driving, so that the traction assembly drives cross bridging to realize extension, and then the flexible adjustment effect of the distance between the two vertical rods is realized, so that the anti-climbing range of the device can be adjusted according to actual needs, and the protection effect on the crane main bodyis realized; and the arranged walking wheels can stably move under the action of the anti-skid mechanisms and can adapt to rugged terrains, the stability of the adjusting process is guaranteed, and the anti-climbing effect of the crane main body is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a tower crane with an anti-climbing function. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as cranes, aerial cranes, cranes, and tire cranes, the main features are: the driving cab and the lifting control room are combined into one, and it is evolved from a crawler crane. The chassis with tires overcomes the shortcomings of crawler cranes that cause damage to the road surface, and belongs to material handling machinery. The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials. , not hinde...
