Before the technical solutions of the present application are introduced, it is necessary to explain the background of the invention of the present application.

It is common in the related art that most of the steel gallery installation methods are integrally hoisted in place by using a large-tonnage crane. The steel gallery is first divided into sections or slices at the fabrication site, depending on the size of the vehicle that can be transported. And then, finding an open field near the installation position of the corridor, and splicing the segmented or flaky corridor into a whole by using a small crane. And then, hoisting the assembled vestibule on the support by using a large crane, and carrying out positioning, adjustment and welding. In general, most steel structure vestibules are more than 20 meters in length and more than 20 tons in weight. However, the method needs to reserve the assembly site of the corridor and the required position of the large crane, and the requirement on the site is high. Meanwhile, the large crane is used more, and the construction cost is correspondingly higher.

Based on the difficult problem that the inventor realizes the installation difficulty caused by the limited installation space, the inventor provides the installation device of the limited space steel gallery. When the steel gallery is installed, the steel gallery is firstly conveyed to the vicinity of an installation position in a loose piece mode, component materials to be assembled into the steel gallery are hung on a hanging piece, the rotation posture of a track is adjusted through a spherical hinge assembly, the component materials are located at proper height positions through the lifting of the hanging piece until the installation components are stacked to a specified position, and the steel gallery is assembled by the component materials. Not only practiced thrift crane machinery bench working cost, reduced the interim area of taking up an area of construction, solved that steel construction installation working face is little, the place is narrow, can't use hoist and mount machinery scheduling problem, reduced the steel vestibule installation degree of difficulty. Therefore, the invention is created.

With reference to fig. 1 and 2, the present application provides a mounting device for a confined space steel gallery, having a hoisting mechanism 100, said hoisting mechanism 100 comprising:

a support platform 120;

a hanger post 110 supported by the support platform 120, the hanger post 110 being divided into a first post 111 and a second post 112 by a ball joint assembly 150, the ball joint assembly 150 being configured to allow the first and second posts 111, 112 to rotate in a plane perpendicular to an axial direction of the hanger post 110;

a rail 130 fixedly connected to the second column 112;

a hoisting connector 140 capable of freely sliding along the rail 130;

and a lifting member 160 which is arranged on the lifting connecting member 140 in a lifting manner.

As a concrete construction of the lifting and lowering movement of the lifting and lowering member 160, an exemplary implementation is that the component for lifting and lowering the lifting and lowering member 160 is a chain block.

Thus, the lifting of the hanging member 160 can be easily performed by manually pulling the chain block.

As an alternative to the chain block, the component for lifting the hanging member 160 may be a pulley 141.

As yet another alternative to the chain block, the component for lifting the hanging member 160 is an electric hoist.

It should be readily appreciated that the implementation of the hanging member 160 may be a hooked rod, or a mechanical grip, etc.

The "plane perpendicular to the axial direction of the hanger post 110" in the rotation of the first and second posts 111, 112 in the plane perpendicular to the axial direction of the hanger post 110 by the front Wen Qiujiao assembly 150 is a plane perpendicular to the extending direction of the post, i.e. the horizontal plane shown in fig. 2.

Referring to fig. 3, as an exemplary implementation of the spherical hinge assembly 150, the spherical hinge assembly 150 includes a base and a ball rod 153 rotatably inserted into the base.

Therefore, the end of the club 153 not inserted into the seat body is fixedly connected with the second column 112, and the seat body is fixedly connected with the first column 111, so that when the club 153 rotates, the relative rotation of the second column 112 and the first column 111 can be realized.

The base body can adopt a split structure, that is, the base body comprises an upper base body 151, a lower base body 152 and a fastening bolt 154 screwed with the upper base body 151 and the lower base body 152 through the fastening bolt 154.

Referring to fig. 4, as an exemplary implementation of the sliding member, the hoisting connection member 140 includes a pulley 141 for being received in the rail 130, an end cap 142 for mounting the pulley 141, and a hanging head 143 for fixedly connecting the end cap 142.

Thus, the pulley 141 is slidably connected to the rail 130, and the hanging head 143 is fixed to the hanging member 160.

The number of sling mechanisms 100 can be set according to the orientation of the placement of the materials of the components to be assembled into the steel gallery. As a practical situation with wider application, the number of the hoisting mechanisms 100 is two, and the two hoisting mechanisms are respectively positioned at the left side and the right side of the corridor to be installed.

The operation process of the construction method of the application is described in a common application scenario. It should be noted that this common embodiment is not to be taken as an identification basis for understanding the essential features of the technical problem to be solved as claimed in the present application, which is merely exemplary.

The construction process comprises the following steps:

s1, two sets of rotatable hoisting devices are obliquely and symmetrically installed on two sides of a corridor to be installed, and the device can realize lifting, front-back movement and 360-degree direction rotation of a component when the component is hoisted.

S2, after the single component of the corridor is manufactured according to the size requirement of the site (the upper chord crossbeam and the lower chord crossbeam are manufactured into two to three sections according to the size), the single component is conveyed to a construction site to be stacked, and then the single component is conveyed to the lower part of the rotatable device by using a trolley according to the installation sequence.

S3, mounting of a lower chord platform: firstly, hoisting the segmented steel gallery bottom chord cross beam in place, and butting and installing the segmented steel gallery bottom chord cross beam in the air by using two rotatable devices. And then the secondary beam and the platform plate are installed to connect the lower chord platform into a whole.

S4, supporting and installing two sides of the corridor: and then, the rotatable device is used for installing the upright posts on the two sides of the frame, the inclined pull flower and other members.

S5, mounting of the upper chord platform: the installation method is the same as that of the winding platform.

And S6, after the corridor is integrated, aligning the central line and the elevation of the corridor.

It should be noted that the present application makes the following obvious intelligent contributions to the related art:

1. the rotatable device is used for hoisting the component, and solves the problem that the mechanical hoisting cannot be used in a limited space!

2. The components are manufactured and transported to the site without assembling and crane station sites. The problems of narrow construction site and no construction operation surface are solved.

3. The rotatable device can also be used for other steel structure installation projects, the use of large-scale hoisting machinery is saved, and the construction cost is reduced.

The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application.
