Abstract
Disclosed is a drill pipe power-assisted fixture complementing a horizontal directional drill, which is characterized in that: the utility model includes a fixture body (1) of a traction handle (5) arranged on the body thereof, a bearing (2), a bearing lining (3) and a taper inner sleeve (6) are orderly arranged in a center hole of the fixture body (1). The utility model has advantages that the fixture can effectively increase the rated pull strength of the horizontal directional drill compared with the prior art, and the operation is easy, more importantly, the utility model can effectively improve the production efficiency and construction quality.
Description
(1) technical field:
The utility model relates to a kind of hole drilling and reaming equipment that is used to lay Urban Buried Pipeline Network, relates to a kind of specifically and the matching used drilling rod power-assisted of horizontal directional drill jig.
(2) background technique:
Raising along with urban construction, management modernization level, the laying amount of industry underground pipe networks such as closely-related electric power, heating power, communication, tap water of living with people is also increasing, for not influencing people's normal life order, traditional broken road trench digging method of construction has been listed in the method for construction that bans use of in most cities, the trenchless technology that replaces also just arises at the historic moment, and becomes one of main construction method of Urban Buried Pipeline Network laying.Adopt trenchless technology lay the construction principle of underground utility and method be boring → → reaming → return hauling pipe road.The key point of this technology is exactly reaming and goes back to the hauling pipe road.When carrying out reaming and returning the hauling pipe procedure, owing to be full of mud in the hole, hole in addition rebound elasticity shrinkage cavity under ground pressure, its resistance will be far longer than the specified pulling force (this situation is in cross river pipeline construction, and is the most common during construction under chiltern, the mud condition) of horizontal directional drill.For above-mentioned condition, mostly prior art is that employing solves in the method that rear end of pipeline installs assist device additional.But the very difficult pull-back force with horizontal directional drill of assist device is synchronous in practice of construction, operates the restriction of defect subspaces and assist device stroke in addition, can bring inconvenience to construction, will directly have influence on construction speed and construction quality.
(3) summary of the invention:
The purpose of this utility model provides a kind of that can effectively increase the specified pull-back force of horizontal directional drill and the matching used drilling rod power-assisted of horizontal directional drill jig with regard to being to overcome above-mentioned deficiency of the prior art.
The purpose of this utility model can realize by following measure:
Drilling rod power-assisted jig of the present utility model comprises that its body is provided with the jig body of traction handle, is equipped with successively in bearing, bearing inner sleeve and the taper in the center hole of described jig body and overlaps.
For making jig of the present utility model can make things convenient for, hold securely drilling rod, cover is to be buckled mutually and formed by two taper watt covers that adopt elastic material to make in the described taper, and its longitudinal section is a wedge-shaped structure.
The cone structure of the inwall of the bearing inner sleeve described in the utility model for matching with the male cone (strobilus masculinus) that overlaps in the taper; Described bearing and bearing inner sleeve are packed in the center hole of jig body by platen; Described traction handle is symmetricly set on the both sides of jig body.
Working principle of the present utility model is as follows:
After boring finishes, drilling rod power-assisted jig of the present utility model is sleeved on (described drilling rod power-assisted jig combines with the traction gear of being made up of portal frame, winch by the traction of the horizontal adjustemt on the both sides traction handle that is mounted on its body drag hook) on the drilling rod, just can effectively increases the specified pull-back force of horizontal directional drill.When carrying out reaming and returning the hauling pipe procedure, start traction gear and the horizontal directional drill formed by portal frame and winch simultaneously, can finish reaming high-quality and efficiently and return the work of hauling pipe road.
The utility model not only has the specified pull-back force that can effectively increase horizontal directional drill compared to existing technology, and the advantage of easy operating, and main is effectively to enhance productivity and construction quality.

Fig. 1 is a plan view of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is a user mode reference drawing of the present utility model.
(5) embodiment:
The utility model is done with detailed description below with reference to embodiment's (accompanying drawing):
As shown in Figure 1, 2, drilling rod power-assisted jig of the present utility model comprises that its body is provided with the jig body 1 of traction handle 5, and cover 6 in bearing 2, bearing inner sleeve 3 and the taper is installed in the center hole of described jig body (1) successively; Cover 6 is to be buckled mutually and formed by two taper watt covers that adopt elastic material to make in the described taper, and its longitudinal section is a wedge-shaped structure; The cone structure of the inwall 4 of described bearing inner sleeve 3 for matching with the male cone (strobilus masculinus) of cover 6 in the taper; Described bearing 2 and bearing inner sleeve 3 are packed in the center hole of jig body (1) by platen 7; Described traction handle 5 is symmetricly set on the both sides of jig body.
Fig. 3 is a user mode reference drawing of the present utility model.8 is drilling rod power-assisted jigs of the present utility model among the figure, the 9th, be mounted on the horizontal adjustemt traction drag hook on the traction handle of the utility model both sides, and the 10th, traction steel rope of cable, the 11st, winch, the 12nd, horizontal directional drill drilling rod, the 13rd, portal frame.Its working principle is as follows: after boring finishes, drilling rod power-assisted jig of the present utility model is sleeved on the drilling rod, described drilling rod power-assisted jig overlaps in by taper under the effect of horizontal adjustemt traction drag hook and the traction gear is made up of portal frame, winch and hugs drilling rod, meanwhile start horizontal directional drill, under the acting in conjunction of traction gear and horizontal directional drill, can finish reaming high-quality and efficiently and return the work of hauling pipe road.
