Description

Quick lifting device of vertical tuber pipe

Technical Field

The utility model belongs to the field of lifting tools, and particularly relates to a quick lifting tool for a vertical air duct.

Background

The air pipes are pipeline systems for air transportation and distribution and are generally divided into vertical air pipes and transverse air pipes according to different installation states. Whether the air pipes are horizontal air pipes or vertical air pipes, the air pipes are assembled by field hoisting in the installation process, and the hoisting is carried out by using a lifting appliance.

For example, chinese patent publication No. CN213950328U discloses an adjustable vertical lifting tool for an air duct, which comprises a cross arm, two rectangular lifting frames and lifting lugs; two rectangular hanging frames are respectively connected to two ends of the cross arm, the rectangular hanging frames are formed by assembling four perforated C-shaped steels through angle connection, the length of an air pipe which can be hung is adjusted by adjusting the distance between the two rectangular hanging frames of the cross arm through an angle connecting piece, the length of the long side or the short side of the two rectangular hanging frames is adjusted through the angle connecting piece, the hanging of pipe sections connected with different air pipe sizes is achieved, the cross arm is the perforated C-shaped steel, and lifting lugs are welded on the upper portion of the cross arm.

In the prior art, the lifting tool is similar to the lifting tool, the C-shaped steel is in contact with the air pipe, and particularly the bottom surface of the C-shaped steel is locked with the side wall of the air pipe through a screw, so that the lifting tool is suitable for lifting the transverse air pipe. For the vertical air pipe, because vertical hoisting is needed, the C-shaped steel needs to be locked on the end face of the pipe orifice through the screw, the thickness of the end face of the pipe orifice (namely the thickness of the pipe wall) of the vertical air pipe is generally thinner, the screw is not easy to be perpendicular to the end face of the pipe orifice to be penetrated in, the problems that the pipe orifice is deformed, the screw is exposed and the like can be caused by forced penetration of the screw are solved, and therefore, for the vertical air pipe, the hoisting cannot be realized through the C-shaped steel in the prior art, and therefore, a new scheme is needed to solve the hoisting problem of the vertical air pipe.

Disclosure of utility model

Aiming at the defects existing in the prior art, the utility model aims to provide a quick vertical air pipe hoisting tool which can be connected with the side wall of an opening of a vertical air pipe, and solves the problem that an existing C-shaped steel hoisting tool cannot be installed due to too small wall thickness of the opening end of the air pipe.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the utility model provides a quick lifting device of vertical tuber pipe, includes the angle steel that two symmetries set up, the angle steel divide into diaphragm and longitudinal plate, a plurality of hole sites have been seted up on the longitudinal plate, two be connected with the tie-beam between the angle steel, be equipped with the lug on the tie-beam.

The advantages according to this solution are at least: the C-shaped steel structure in the prior art is changed into angle steel, so that the angle steel is easier to obtain in engineering on one hand, and on the other hand, the angle steel can be connected with the side wall of the opening of the vertical air duct through the longitudinal plate of the angle steel, and the problem that an existing lifting appliance cannot be installed due to too small wall thickness of the opening end of the air duct is solved.

The utility model is further provided with: the longitudinal plates of the two angle steels are positioned at one ends of the transverse plates, which are close to each other.

The utility model is further provided with: the connecting beam is provided with at least one connecting beam.

The utility model is further provided with: and a plurality of standby hole sites are arranged on the transverse plate.

In summary, the present utility model has at least the following advantages:

1. The C-shaped steel structure in the prior art is changed into the angle steel, so that the angle steel is easier to obtain in engineering on one hand, and on the other hand, the angle steel can be connected with the side wall of the opening of the vertical air pipe through the longitudinal plate of the angle steel, so that the problem that the existing lifting appliance cannot be installed due to the fact that the wall thickness of the opening end of the air pipe is too small is solved;

2. through setting up reserve hole site, not only can play reserve effect, use hole site and reserve hole site simultaneously can improve the stability of hoist and mount moreover.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the quick lifting device for a vertical air duct comprises two symmetrically arranged angle steels 1, wherein each angle steel 1 is divided into a transverse plate 11 and a longitudinal plate 12, a plurality of hole sites 2 are formed in the longitudinal plate 12, in some preferred embodiments, a plurality of standby hole sites (not shown in the drawings) are formed in the transverse plate 11, and the hole sites 2 on the transverse plate 11 and the longitudinal plate 12 can be through holes or threaded holes for bolts to pass through. A connecting beam 3 is connected between the two angle steels 1, the connecting beam 3 can also be in the shape of the angle steels 1, a lifting lug 4 is arranged on the connecting beam 3, and the lifting lug 4 is preferably made of round steel.

In some embodiments, the longitudinal plates 12 of the two angle steel 1 are positioned at the ends of the transverse plates 11 close to each other, so that the longitudinal plates 12 can be mounted inside the air duct 5 (as shown in fig. 1) during the lifting process.

In some embodiments, the connecting beam 3 is provided with at least one, and in case of a large inner diameter of the pipe orifice, the connecting beam 3 is preferably provided in a plurality to improve the structural stability of the spreader.

The working process and the beneficial effects of the utility model are as follows: when the lifting tool of the scheme is installed, the vertical plate 12 is installed on the inner wall or the outer wall of the air pipe 5 machine through bolts and nuts, so that the lifting tool of the vertical pipeline can be installed. The vertical plate 12 through angle steel 1 realizes being connected with vertical tuber pipe 5 opening lateral wall in this scheme, solves the problem that current C shaped steel hoist can't be installed because of tuber pipe 5 open end wall thickness is too little.
