Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] see figure 1 , The novel tower crane of the present invention comprises a foundation 1, a tower body 2, a slewing tower body 3, a jib 4, a wire rope 5 and a driver's cab 6. There is a slewing mechanism in the slewing tower body 3, such as figure 1 Shown in the boxed P section. see figure 2 , shows an enlarged view of this P section. The slewing mechanism includes a brake 7, a motor 8, a reducer 9, a slewing pinion 10 and a slewing bearing 11. The slewing bearing 11 is supported on the lower tower body, and the motor 8 drives the slewing pinion 10 through the reducer 9 to drive the upper tower body to rotate. A limiter pinion 13 installed in mesh with the slew bearing 11 is connected to the slew limiter 12 . see you again image 3 , The rotation limiter 12 includes a travel limiter 14 , a universal joint 15 , a bow plate 16 , a limiter pinion 17 and a co...

Abstract

The invention provides a novel tower crane, which includes a foundation (1), a tower body (2), a rotary tower body (3), a jib (4), a steel wire rope (5) and a driver's cab (6). A rotary mechanism is disposed in the rotary tower body (3), and the rotary mechanism comprises a brake (7), an electromotor (8), a speed reducer (9), a rotary pinion (10) and a rotary bearing (11). The rotary bearing (11) is supported on the lower part of the tower body (2), and the electromotor (8) drives the rotary pinion (10) to bring the upper tower body into rotation through the speed reducer (9). The novel tower crane adopts the novel rotary mechanism, so that operation of the novel tower crane provided in the invention can be safer and more reliable.

Description

technical field [0001] The invention belongs to the field of engineering machinery, and in particular relates to a novel tower crane. Background technique [0002] With the development of society, the use of tower cranes is becoming more and more frequent, and the high-load work of operators leads to frequent operating errors. To reduce the occurrence of mistakes, on the one hand, it is necessary for the personnel to take a reasonable rest, and on the other hand, it is also necessary to improve the mechanism to limit some excessive operations. Contents of the invention [0003] The invention improves the slewing mechanism of the tower crane, so that the tower body cannot be over-rotated, thereby greatly improving the safety, and more meeting the needs of the current society. The scheme that the present invention adopts is as follows: [0004] A new type of tower crane, comprising a foundation 1, a tower body 2, a slewing tower body 3, a boom 4, a wire rope 5 and a driver...
