mast lifting device

Abstract

The invention provides a mast hoisting device, and belongs to the technical field of cranes. The mast hoisting device comprises a main mast, a hoisting mast, lifting equipment and a fixing base. A rotary seat is arranged on the fixing base, the main mast is arranged on the fixing base through the rotary seat, a hawser for keeping the main mast upright and stable is arranged on the top of the mainmast, the hoisting mast is hinged to the main mast, the lifting equipment is arranged on the main mast, the lifting end of the lifting equipment is wound around the free end of the hoisting mast to besuspended in midair, and an amplitude variable steel wire rope for changing the angle between the hoisting mast and the main mast is further arranged on the main mast. The mast hoisting device can bemounted at different positions according to different conditions, heavy objects can be hoisted to the positions higher than the hoisting heights of the heavy objects through the mast hoisting device,and therefore the mast hoisting device is more convenient to use.

Description

technical field

[0001] The invention relates to the field of cranes, in particular to a mast hoisting device. Background technique

[0002] The mast crane is a fixed-installed crane. The mast crane has the characteristics of simple structure, easy design and manufacture, low cost, easy disassembly, small weight and large capacity. Mast cranes are generally used in occasions such as heavy components, relatively concentrated hoisting projects, and narrow construction sites, such as docks, ports, mines, etc.; however, mast cranes in the prior art can only be installed on the ground. , and the height of the lifting weight is limited by its own structure, so that the existing mast crane can only lift the heavy object to a certain height; for example, the lifting height of some lifting devices is only 30m, and when the required lifting When the set height exceeds 30m, the hoisting device will not be able to complete the lifting work. In order to complete the lifting work, it is n...

[0032] Embodiment 1, with reference to Figure 1 to Figure 3 as shown,

[0033] A mast hoisting device, including a main mast 1, a lifting mast 2, a lifting device and a fixed base 3; wherein,

[0034]The fixed base 3 is provided with a swivel seat 4, the main mast 1 is arranged on the fixed base 3 through the swivel seat 4, and the top of the main mast 1 is provided with a cable wind rope 5 for keeping the main mast 1 upright and stable, and the lifting mast 2 is hinged On the main mast 1, the hoisting equipment is arranged on the main mast 1, and the hoisting end of the hoisting equipment bypasses the free end of the hoisting mast 2 and is suspended in the air. The angle between the luffing wire rope 6. Through a kind of mast hoisting device with the above structure, the mast hoisting device can be installed in different positions according to different situations, for example, the hoisting height of the hoisting device is 30m, and the required hoisting height requires At...

Embodiment 2

[0043] Embodiment 2 refers to Figure 1 to Figure 3 as shown,

[0044] The implementation principle and technical effect of the device provided by the embodiment of the present invention are the same as those of Embodiment 1. For a brief description, reference may be made to the corresponding content in Embodiment 1 for the parts not mentioned in this embodiment.

[0045] The device obtained through the above design can basically meet the use of the mast lifting device, but in line with the purpose of further improving its function, the designer has made further improvements to the device.

[0046] The above-mentioned lifting equipment includes a winding device 10 and a hook 11;

[0047] Wherein, the winding device 10 is wound with a lifting steel rope 12, and one end of the lifting steel rope 12 is fixed on the winding device 10, that is, the fixed end of the lifting steel rope 12 is fixedly connected with the winding device 10, thereby effectively avoiding When the winding...

Embodiment 3

[0052] Embodiment 3 refers to image 3 and Figure 4 as shown,

[0053] This embodiment provides a mast hoisting device with another structure, which is a further improvement of the above-mentioned embodiment 1 and embodiment 2; wherein, the mast hoisting device also includes a movable pulley 15 and a supporting cross bar 14. The support bar 14 is connected to the main mast 1, and the length direction of the support bar 14 is perpendicular to the length direction of the main mast 1, and the above-mentioned hook 11 is suspended on the movable pulley 15, and the free ends of the hoisting steel rope 12 are sequentially Go around the second fixed pulley 13 and the movable pulley 15, and connect and fix with the support cross bar 14; the setting of the movable pulley 15 makes the winding process of the winding device 10 easier when the mast hoisting device is lifting heavy objects , so that the mast hoisting device can hoist heavier weights.
