Description
Technical Field
The utility model relates to the field of building construction, in particular to a simple shaft hoisting device in municipal pipe network construction.
Background
In the construction of current municipal pipe network, concrete shaft is the construction material that pipe network inspection shaft construction is commonly used, in pit shaft production, transportation, installation process, often need hoist and mount operation, because the pit shaft is vertical drum structure, and bulky, heavy, do not have hoist and mount stress point, lead to hoist and mount degree of difficulty big, the potential safety hazard is high, has the condition that takes labor and effort, work efficiency is low.
Disclosure of Invention
In order to solve the problems of high lifting difficulty, high potential safety hazard and low construction efficiency, the utility model provides a simple lifting device for a shaft, which has a simple structure and is quick to lift.
The technical scheme adopted by the utility model for achieving the purpose is as follows: simple and easy hoist device of pit shaft, its characterized in that: including activity cross clamp, hoist and mount portion, activity cross clamp includes first clamping lever and second clamping lever, and two clamping lever middle parts are scissors form articulated connection through the round pin axle, the lower extreme of first clamping lever and second clamping lever is equipped with the clamping part, and the clamping part adopts the arc steel sheet, and the inside lining surface is the rubber gasket of dull polish form, the lifting hole that is used for rope hoist and mount is left to the upper end of first clamping lever and second clamping lever.
The thickness of the rubber gasket is 2cm, and the rubber gasket is anchored on the arc-shaped steel plate through bolts.
The arc-shaped steel plate corresponds to a central angle of 90 degrees, and the corresponding circle radius is larger than the outer diameter of the pre-hoisted shaft by 3cm.
The first clamping rod and the second clamping rod comprise a Y-shaped rod and a horizontal rod which are integrally connected, the lower end of the Y-shaped rod is welded with the clamping part, and the tail end of the horizontal rod is provided with a hoisting hole.
The length of the Y-shaped rod is 1270mm, and the length of the horizontal rod is 300mm.
The simple shaft hoisting device provided by the utility model can hoist the vertical shaft at one time, reduces the time of manual bundling and fixing, and improves the working efficiency; the damage to the shaft body in the hoisting process is reduced, and the material loss is reduced; the operation is simple, when pit shaft and grip block contact, utilize the rotation of clamp lever, make splint and pit shaft contact completely, increase frictional force, the factor of safety when improving to hoist.
Drawings
Fig. 1 is a front view of the structure of the present utility model.
Fig. 2 is a top view of the structure of the present utility model.
In the figure: 1. the steel plate lifting device comprises a rubber gasket, an arc-shaped steel plate, bolts, a first clamping rod, a second clamping rod, a pin shaft and a lifting hole.
Detailed Description
The utility model will now be described in detail with reference to the drawings and examples.
The simple lifting device for the shaft comprises a simple lifting device for the shaft, and comprises a movable cross clamp, a lifting part and a clamping part, wherein the movable cross clamp comprises a first clamping rod 4 and a second clamping rod 5, the middle parts of the two clamping rods are in scissor-shaped hinged connection through a pin shaft 6, the lower ends of the first clamping rod 4 and the second clamping rod 5 are provided with the clamping part, the clamping part adopts an arc-shaped steel plate 2, the surface of an inner lining is provided with a frosted rubber gasket 1, and lifting holes 7 for rope lifting are reserved in the upper ends of the first clamping rod 4 and the second clamping rod 5.
The thickness of the rubber gasket 1 is 2cm, and the rubber gasket is anchored on the arc-shaped steel plate 2 through bolts 3.
The arc-shaped steel plate 2 corresponds to a central angle of 90 degrees, and corresponds to a circle radius which is 3cm larger than the outer diameter of the pre-hoisted shaft.
The first clamping rod 4 and the second clamping rod 5 comprise a Y-shaped rod and a horizontal rod which are integrally connected, the lower end of the Y-shaped rod is welded with the clamping part, and the tail end of the horizontal rod is provided with a hoisting hole 7.
The length of the Y-shaped rod is 1270mm, and the length of the horizontal rod is 300mm.
The simple shaft hoisting device comprises the following specific operation steps:
firstly, one end of a hoisting rope is bound and fixed through a hoisting hole 7, and the other end of the hoisting rope is connected and fixed with a hoisting machine;
secondly, lifting the lifting device by using a crane, and placing the arc-shaped steel plates 2 of the clamping part on two sides of a shaft to be lifted;
and thirdly, the hoisting machine lifts the hoisting rope again, the clamping part is stressed and contracted under the action of the hoisting machine, the hoisting rope and gravity, namely, the intervals between the arc-shaped steel plates 2 at the two sides are reduced, so that the shaft is clamped, and the shaft is lifted.
Finally, after the shaft is installed and positioned, the hoisting machine releases the hoisting rope, and the clamping part is opened.
The embodiments of the present utility model have been disclosed above, but are not limited to the use as set forth in the specification and embodiments, which are well suited to various fields of use for the utility model, and further modifications will be readily apparent to those skilled in the art, and accordingly, the utility model is not limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.
