Abstract

The utility model belongs to drill field and relates to a pump suction direct and reverse circulation percussion drill used in irrigation and construction works. The percussion drill is mainly characterized in that a slurry suction pump is connected at the outlet of a water filling rubber tube of a slurry pump; the slurry pump and the slurry suction pump are connected in a clutched way; and the tail end of a wire rope of an auxiliary windlass is movably connected with a downcast slurry suction pump through a guide wheel. The percussion drill can make use of direct and reverse circulation to follow a percussion hammer to continuously prepare the slurry bidirectionally and to discharge the slag and clean the holes. The percussion drill is convenient for the replacement and connection of the slurry suction pipes, and has the advantages that the percussion drill can prepare the slurry quickly, discharge the slag and clean the holes timely, improves the drilling speed, saves power and reduces the labor intensity.

Description

Pump is inhaled the positive and negative circulation impact rig

Technical field

The utility model belongs to the rig field, relates to water conservancy, percussive drill for building, is specifically related to a kind of pump and inhales the positive and negative circulation impact rig.

Background technology

Existing water conservancy drilling well and road, bridge, the boring percussive drill of house foundation pile, its structure comprises: support, king-post, diagonal member, the head sheave at the cable wire pile warp king-post top of main winch is connected with jump bit, downward percussion drilling, with slush pump by sebific duct water filling and wash in a pan behind the mud bucket modulation mud to the aboveground spoil disposal screenings of carrying in pit shaft by artificial usefulness, jump bit is out of service when carrying the spoil disposal screenings creeps into, it is big to exist mud modulation and the clear hole of deslagging difficulty, drillng operation is discontinuous, and labour intensity is big, the defective that drilling efficiency is low.

The utility model content

The designer finds that existing rig exists above-mentioned defective in the manufacturing of being engaged in rig for many years, use and practical activity, through investigation, update, and purpose is to develop a kind of pump and inhales the positive and negative circulation impact rig.

Technical solution adopted in the utility model is that a kind of pump of design is inhaled the positive and negative circulation impact rig, its structure comprises: the percussive drill support, king-post, diagonal member, the cable wire of main winch is walked around the head sheave of land wheel through the king-post top and is connected with jump bit, and it is connected with pulp absorbing pump and goes into the well pulp-absorbing pipe in the outlet of water filling sebific duct of slush pump, is connected by clutch between slush pump and the pulp absorbing pump, secondary hoist engine is set, the terminal pile warp directive wheel of the cable wire of secondary hoist engine with go into the well pulp-absorbing pipe and flexibly connect.

The utility model is owing to adopt abovementioned technology that existing percussive drill is improved, set up pulp absorbing pump after, can utilize anti-circulation and slush pump direct circulation collaborative mutually, two-way mud, the pump drainage screenings modulated continuously of jump bit realization follows up; After setting up secondary hoist engine, can conveniently go into replacing, continued access and the follow-up suction mud and the clear hole of deslagging of well pulp-absorbing pipe in the anti-cycle operation process of pulp absorbing pump, it is fast to have modulation mud, the clear hole of deslagging is timely, rate of penetration improves, and saves power source, remarkable advantages such as labour intensity reduction.

Description of drawings

Fig. 1 represents the general structure schematic diagram of the utility model pump suction positive and negative circulation impact rig.

The specific embodiment

Reach embodiment in conjunction with the accompanying drawings, further specify the concrete structure that the utility model pump is inhaled the positive and negative circulation impact rig, its feature and advantage are clearer.

The utility model pump is inhaled the embodiment of positive and negative circulation impact rig, referring to Fig. 1, its structure comprises: percussive drill support 1, king-post 6, diagonal member 4, the cable wire 3 of main winch 2 is walked around the head sheave 5 of land wheel 10 through king-post 6 tops and is connected with jump bit 9, outlet at the water filling sebific duct 13 of slush pump 14 is connected with pulp absorbing pump 12 and goes into well pulp-absorbing pipe 8, be connected by the clutch (not shown) between slush pump 14 and the pulp absorbing pump 12, nearly pulp absorbing pump 12 places are provided with small-sized secondary hoist engine 11 on support 1, behind the cable wire 7 pile warp directive wheels terminal hook with go into well pulp-absorbing pipe 8 hook flexible connection mutually.

Model machine is test at the scene after trial-production, fast 2 times than former machine in modulation mud, fast 5 times than former machine of clear hole deslagginves, fast 1 times than former machine of rate of penetration.To creep into 60 meters wellholes is example, former machine modulation mud, the clear Kong Gongxu of deslagging 40 hours, and existing experimental prototype only needs 2 hours, and energy consumption minimizing, is equipped with motor and changes 50KW into by 70KW.

Claims

1, a kind of pump is inhaled the positive and negative circulation impact rig, comprise the percussive drill support, king-post, diagonal member, the cable wire of main winch is walked around the head sheave of land wheel through the king-post top and is connected with jump bit, it is characterized in that being connected with pulp absorbing pump and going into the well pulp-absorbing pipe in the outlet of the water filling sebific duct of slush pump, is connected by clutch between slush pump and the pulp absorbing pump, secondary hoist engine is set, the terminal pile warp directive wheel of secondary hoist engine cable wire with go into the well pulp-absorbing pipe and flexibly connect.
