Embodiment 1

[0043] figure 2 Schematic diagram of the front structure of the low headroom lifting device provided by Embodiment 1 of the present invention; image 3 A top view of the low headroom lifting device provided by Embodiment 1 of the present invention; Figure 4 The left view of the low-headroom lifting device provided by Embodiment 1 of the present invention; Figure 5 It is a schematic diagram of the bending structure of the low-headroom hoisting device provided by Embodiment 1 of the present invention.

[0044] Such as Figure 2 to Figure 5 As shown, the low headroom lifting device provided by the embodiment of the first aspect of the present invention includes: a housing 13, a spreader 16, a walking unit and a lifting unit; 1. A moving traveling motor, the lifting unit includes a lifting motor 10 that drives the spreader 16 up and down, and the lifting motor 10 and the traveling motor are respectively arranged on both sides of the running track 1 .

Embodiment 2

[0064] The traveling mechanism in the second embodiment is a gear, and the running track 1 is provided with a rack meshing with the gear.

[0065] The structure of the gear and the rack can also ensure that the device does not slip on the running track 1 with a certain slope. The rest are the same as the first embodiment, and will not be repeated here.

[0066] To sum up, in the low-headroom lifting device provided by the present invention, the lifting motor and the traveling motor are respectively arranged on both sides of the running track, which not only can greatly reduce the headroom of the whole device, but also can grasp heavy objects. Take higher. At the same time, it can also make the weight distribution of the whole device reasonable, and the center of gravity is on the center line of the running track, which has the advantages of low headroom and structural size.

Abstract

The low-headroom hoisting device and the hoisting system provided by the present invention relate to the technical field of engineering and construction. The low-headroom hoisting device includes: a casing, a spreader, a traveling unit and a hoisting unit; the traveling unit includes driving the casing The hoisting unit includes a hoisting motor that drives the spreader to lift and lower, and the hoisting motor and the traveling motor are respectively arranged on both sides of the running track. In the low-headroom hoisting device provided by the present invention, the hoisting motor and the traveling motor are respectively arranged on both sides of the running track, which can not only greatly reduce the clearance of the whole device, but also can grab heavy objects higher. At the same time, it can also make the weight distribution of the whole device reasonable, and the center of gravity is on the center line of the running track, which has the advantages of low headroom and structural size.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a low headroom lifting device and a lifting system. Background technique [0002] The climax of domestic subway construction has kicked off, and my country has become the world's largest shield machine market. The shield segment is the main assembly component of shield construction and the innermost barrier of the tunnel, which bears the role of resisting soil pressure, groundwater pressure and some special loads. The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. [0003] As an indispensable part of the shield machine, the segment crane used for hoisting the shield segment has a higher and higher market value. The height of the tunnel is low. In view of the constructi...
