Description

Novel electric sliding type top iron

Technical Field

The invention relates to the technical field of pipe jacking construction, in particular to a novel electric sliding type jacking iron.

Background

The pipe jacking technology is more and more widely applied to municipal engineering underground pipelines, but in the pipe jacking construction process, because prefabricated pipe joints are installed, the jacking iron of the jack needs to return again, the jacking iron needs to be moved ceaselessly, the jacking iron is heavy, the jacking iron needs to be hoisted by a crane when being moved each time, the jacking iron is moved slowly and needs to be adjusted to be in place, a large amount of time is wasted, the cost is increased, the pipe jacking construction efficiency is not improved, meanwhile, the jacking iron often collides with the following jack when being moved, and the equipment is not safe and is easy to damage.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides a novel electric sliding type jacking iron, which solves the problems that in the jacking construction process, because a prefabricated pipe joint is installed, the jacking iron of a jack needs to return again, the jacking iron needs to be moved ceaselessly, the jacking iron is heavy, and the jacking iron needs to be hoisted by a crane during each movement, moved slowly and adjusted to be in place, so that a large amount of time is wasted, the cost is increased, the jacking construction efficiency is not improved, and meanwhile, the jacking iron often collides with the jack behind when being moved, so that the equipment is not safe and is easily damaged.

(II) technical scheme

In order to achieve the purpose, the invention is realized by the following technical scheme: a novel electric sliding type ejector iron comprises a U-shaped ejector iron, wherein a semicircular ejector iron is arranged at the top of the U-shaped ejector iron, a sliding roller system is arranged at the bottom of the U-shaped ejector iron, rails are arranged on two sides of the bottom of the sliding roller system, and a winch drag ring is arranged on the front surface of the semicircular ejector iron;

the sliding roller system comprises a body, and a roller 1, a roller 2 and a roller 3 are respectively arranged on the body.

Preferably, a threaded hole is formed in the U-shaped top iron.

Preferably, both sides of the top of the U-shaped top iron are provided with hanging rings.

(III) advantageous effects

The invention provides a novel electric sliding type top iron. The method has the following beneficial effects: this novel electronic slidingtype ejector iron, with former ejector iron and track face stationary contact adjustment for recess slidingtype contact, make the recess at ejector iron contact site according to orbital size promptly, the recess sets up the sliding roller of stainless steel with the three contact surface of guide rail, the cylinder axle center can adopt screw or welded fastening with the ejector iron, cylinder 2, cylinder 3 and 1 perpendicular dislocation set of cylinder, ejector iron forms the glide plane with the track like this, frictional force is little, the accessible hoist engine directly pulls and returns the position ejecting ejector iron again, need not to readjust and correct the ejector iron position, it lifts by crane and transfers the ejector iron link repeatedly to save the centre, a large amount of time has been saved, the construction speed is advanced in the push pipe top, construction cost has been practiced thrift.

FIG. 2 is a schematic view of the construction of the sliding roller system of the present invention;

fig. 3 is a comparative schematic view of the drum 1, drum 2 and drum 3 of the present invention.

In the figure: 1. a hoisting ring; 2. a threaded hole; 3. a sliding roller system; 4. u-shaped top iron; 5. a semicircular top iron; 6. a winch drag ring; 7. a track.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a novel electric sliding type ejector iron comprises a U-shaped ejector iron 4, wherein a threaded hole 2 is formed in the U-shaped ejector iron 4, hanging rings 1 are arranged on two sides of the top of the U-shaped ejector iron 4, a semicircular ejector iron 5 is arranged on the top of the U-shaped ejector iron 4, a sliding roller system 3 is arranged at the bottom of the U-shaped ejector iron 4, rails 7 are arranged on two sides of the bottom of the sliding roller system 3, and a winch towing ring 6 is arranged on the front surface of the semicircular ejector iron 5;

the sliding roller system 3 comprises a body on which a roller 1, a roller 2 and a roller 3 are respectively arranged.

Firstly, when the top iron is manufactured in a factory, two strip-shaped grooves are arranged according to the interval of the tracks, three surfaces of each groove are installed by a stainless steel roller, the groove behind the roller is ensured to be wider than the tracks by 3cm, normal placement of the top iron is ensured, the depth of each groove and the thickness of each track are equal in height, the friction force between the top iron with the rollers and the track surface can be reduced, and after jacking of a pipe joint is finished, the top iron can be dragged back to the original position by a winch.
