Abstract

The utility model relates to an underground horizontal underreamer which belongs to the technical field of engineering machinery. The utility model is composed of a hoist 4, a support plate 3, a reverse pulling rope 1, an underreamer, etc., wherein, the underreamer is provided with an inner ground cutting plate 13 which is arranged between a circular pipe 11 and a center shaft 14, and a baffle plate 15 can be matched with the inner ground cutting plate. The utility model which can be matched with a perforating machine has the advantages that a hole can be reamed into a required size, roadway traffic can not be influenced, and simultaneously, work efficiency can be enhanced.

Description

Underground horizontal underreamer

The utility model belongs to technical field of engineering machinery, relates to a kind of cable layings such as highway, railway that cross, tap water, and roads such as coal gas are perforation engineering apparatus down.

At present, the tubing great majority adopt the method for laying behind the hand digging road surface, and its efficient is low, and destroying the road surface influences the traffic and the appearance of the city.

The purpose of this utility model provides a kind of under the situation of not destroying the road surface, is used and can expands into necessary requirement to the hole exactly with punch, the following perforation in the road engineering equipment that efficient is higher.

The utility model know-why is as follows:

All device is by hoisting machine 4, gripper shoe 3, fall compositions such as pull rope 1 and reamer 2, reamer 2 is that 2-6 sheet inscribe soil plate 13 is arranged in garden pipe 11, central axis 14 two ends of reamer are fixed with draw hook 12, and inscribe soil plate 13 is fixed between garden pipe 11 and the central axis 14, and it is plane or wavy surface that the native cutting edge of cutting of 11 1 ends is managed in the garden, two and half garden shape baffle plates 15 are fixed on central axis 14 afterbodys of reamer by screw 16, are mated the cleaning surflaes and use.

The utility model advantage is: be used and the hole can be expanded into required size dimension with punch, neither influence road traffic, improved operating efficiency simultaneously again.
