Embodiment 1

[0083] This embodiment illustrates the jacking system of the present invention.

[0084] The jacking system of this embodiment includes a first brake mechanism, a second brake mechanism and a drive mechanism 20, wherein the first brake mechanism is movably connected with the fixed jacking beam 11 of the sleeve body, and the second brake mechanism is connected with the The movable jacking beam 12 is movably connected, and the driving mechanism 20 is connected with the fixed jacking beam 11 and the movable jacking beam 12 of the frame body, and the driving mechanism 20 is raised or lowered by driving the fixed jacking beam 11 and the movable jacking beam 12 of the frame body And drive the first braking mechanism and the second braking mechanism to rise or fall, and make the first braking mechanism and the second braking mechanism fix with the steps 131a on the H-shaped steel main chord 131 by the effect of dead weight and / or pulling force or separation. Preferably, the driving ...

Embodiment 2

[0093] This embodiment describes the H-shaped steel standard section tower crane of the present invention.

[0094] The H-shaped steel standard section tower crane in this embodiment includes a tower body, an H-shaped steel standard section, a sleeve frame, a movable jacking beam 12 and a jacking system. Wherein, the jacking system is the jacking system of any one of the technical solutions in Embodiment 1, the sleeve frame is sleeved on the tower body, and the jacking system is arranged on the sleeve frame body of the sleeve frame to fix the jacking beam 11 and the movable jacking beam 12 superior.

[0095] The H-shaped steel standard section tower crane of this embodiment performs the process of adding and lowering sections through the semi-automatic braking method of the jacking system of any one of the technical solutions in Embodiment 1. Compared with the traditional H-shaped steel standard section tower crane The braking method of the jacking system has improved its aut...

Embodiment 3

[0097] This embodiment describes the jacking method of the H-shaped steel standard section tower crane in Embodiment 2.

[0098] The jacking method of the H-shaped steel standard section tower crane in this embodiment includes two processes of adding sections and lowering sections. Specifically, the installed standard section of the H-shaped steel standard section tower crane is connected to the ground and is in a fixed state. The sleeve frame body 10 is sleeved on the installed standard section, and the weight of the sleeve frame body 10 is obtained by the first brake. The brake shoe of mechanism and the second braking mechanism is fixed on the step 131a of standard section. In the process of adding and lowering sections of the H-shaped steel standard section tower crane, there is a process of mutual movement between the frame body 10 and the standard section, and the expression is that the frame body 10 passes through the first braking mechanism and The second braking mecha...

Abstract

The invention discloses a jacking system, an H-shaped steel standard knot tower crane and a jacking method of the H-shaped steel standard knot tower crane, and solves the technical problem of low automation degree of a traditional H-shaped steel standard knot tower crane jacking system. The jacking system comprises a first braking mechanism, a second braking mechanism and a driving mechanism, the first braking mechanism is movably connected with a sleeve frame body fixed jacking beam, the second braking mechanism is movably connected with a movable jacking cross beam, the driving mechanism is connected with the sleeve frame body fixed jacking beam and the movable jacking cross beam, the driving mechanism drives the sleeve frame body fixed jacking beam and the movable jacking cross beam to ascend or descend to drive the first braking mechanism and the second braking mechanism to ascend or descend, and the first braking mechanism and the second braking mechanism are fixed to or separated from steps on an H-shaped steel main chord member under the action of self weight and / or pulling force. The jacking system is in a semi-automatic braking mode, and compared with a braking mode of the traditional H-shaped steel standard knot tower crane jacking system, the jacking system has the advantage that the automation degree of the jacking system is improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a jacking system, an H-shaped steel standard section tower crane and a jacking method thereof. Background technique [0002] The jacking system is an important part in the process of adding and lowering sections of tower cranes. The brake of the jacking system is divided into two parts, the upper part is located at the fixed jacking beam of the sleeve frame body, and the lower part is located at the movable jacking beam. The braking of the jacking system of the traditional H-shaped steel standard section tower crane adopts manual push-pull braking for the upper and lower parts. Check whether the brake block is in place many times, and often need to adjust the telescopic adjustment of the oil cylinder to facilitate the push in or pull out of the brake block. Once the brake block is not fully mounted on the standard step, serious safety accidents are likely to occur. Therefore, it...
