Problems solved by technology

In the existing tower crane operation, when the tower crane driver manually climbs the tower crane, there is an operation safety problem; when the tower crane driver goes up and down the tower crane through the elevator, the elevator is installed adjacent to the tower crane, and the guide rail needs to be installed separately. The force is concentrated, and the guide rail is easy to wear and cause safety accidents

[0035] Please refer to figure 1 , this embodiment provides an elevator 100 , which is applied to a tower crane, and includes a car 1 , a driving mechanism 2 and two crawling mechanisms 3 .

[0036] In this embodiment, the driving mechanism 2 is detachably arranged on the car 1, and it is convenient to overhaul the driving mechanism 2 during use; Balanced, the driving mechanism 2 is located between two crawling mechanisms 3. The crawling mechanism 3 includes a crawler belt 31, a driving wheel set 32 ​​and a spur assembly. The crawler belt 31 is a chain ring structure, and the driving wheel set 32 ​​is located in the chain ring. The driving wheel set 32 It is connected with the driving mechanism 2, and the driving wheel set 32 ​​is used to drive the crawler belt 31 to rotate. The shoe shoe assembly is arranged around the axial direction of the crawler belt 31. The shoe shoe assembly is used to cooperate with the ladder of the tower crane and hang the crawler mechanism 3 on the t...

[0060] Please refer to Figure 9 As shown, this embodiment provides a tower crane 400, including a tower crane body 41, a counterweight 42 and the elevator 100 provided in the first embodiment.

[0061] In this embodiment, the tower crane body 41 includes a plurality of standard sections 411, and the plurality of standard sections 411 are stacked vertically to form a tower hanger, such as Figure 10 As shown, the standard section 411 includes a plurality of steps 412 distributed along the length of the standard section 411, and the two ends of the steps 412 are respectively fixed to the standard section 411. The plurality of steps 412 is equivalent to the track for the elevator 100 to move on the tower crane 400. The steps 412 are used for Cooperate with thorn group 33. In order to keep the elevator 100 balanced when moving on the tower crane 400 , a balance weight 42 is provided on the side of the tower crane 400 opposite to the elevator 100 . Balance weight 42 is connected...

Abstract

The invention relates to a lift and a tower crane and belongs to the technical field of building equipment. The lift is applied to the tower crane and comprises a lift car, a driving mechanism and twocrawling mechanisms. The driving mechanism is detachably arranged in the lift car; each of the crawling mechanisms comprises a caterpillar band, a driving wheel set and a shoe assembly; the caterpillar band is of a chain-ring structure, the driving wheel set is located in a chain ring, the driving wheel set is connected to the driving mechanism and is used for driving the caterpillar band to rotate, the shoe assembly is arranged around the periphery of the caterpillar band, and the shoe assembly is used for being matched with a step of the tower crane and suspending the crawling mechanisms onthe tower crane. The lift arranged on the tower crane is small in occupied space, and a tower crane driver can be safely and reliably delivered to a cab, so that the efficiency is improved, and unnecessary troubles of the tower crane driver are avoided; a guide rail is modified by a standard knot of the tower crane and unnecessary guide rails are unnecessarily mounted. The lift can climb on the tower crane initiatively, and is stably connected to the tower crane, so that the safety performance and the comfort performance of the integral lift are improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a lift and a tower crane. Background technique [0002] With the continuous improvement of the level of modern construction, the height of the building is also rising, and the height of the tower crane is also rising accordingly. The tower crane driver manually climbs to the tower crane cab or uses the elevator to get on and off the tower crane. In the existing tower crane operation, when the tower crane driver manually climbs the tower crane, there is an operation safety problem; when the tower crane driver goes up and down the tower crane through the elevator, the elevator is installed adjacent to the tower crane, and the guide rail needs to be installed separately. The force is concentrated, and the guide rail is easy to wear and cause safety accidents. Contents of the invention [0003] The object of the present invention is to provide an elevator and a towe...
