Abstract
The utility model relates to an auxiliary device for a kilometer drilling machine in a coal mine, in particular to a drill rod fishing device for the kilometer drilling machine, and solves the problem of fishing drill rods falling to a special position of a coal bed. The drill rod fishing device for the kilometer drilling machine structurally comprises a pull sleeve, an outer sleeve and an inner sleeve. The pull sleeve is connected with the outer sleeve in a clamped manner, the inner wall of the outer sleeve is a conical inclined plane, the outer wall of the inner sleeve is a conical plane, and a pull ring is arranged outside the pull sleeve. The drill rod fishing device for the kilometer drilling machine is simple in structure, reasonable in design and fine in fishing effect, is mainly used for fishing the drill rods which fall in the coal bed and are not fishing timely and is used in an environment that the drill rods exposed on tunneling roadways cannot be fished by the drilling machine. Therefore, a large amount of equipment funds can be saved for coal mine enterprises.
Description
Technical field
The utility model relates to a kind of colliery with km rig servicing unit, is specially a kind of km borer drill rod fishing device.
Background technology
The km rig is used commonplace in the colliery; Because former drilling rod, inserting tube, the no magnetic drilling rod of when the boring of construction km, falling in the hole fails in time successfully to salvage; When digging laneway, exposed, and the drilling rod position is at top board, the base plate vicinity in tunnel.Because these positions are more special, can't adopt rig directly to salvage.In order not influence coal mining, be badly in need of a kind of easy, the instrument that can effectively drilling rod be taken out.
Summary of the invention
The utility model provides a kind of km borer drill rod fishing device for the problem of the salvaging that solves the drilling rod that specific position drops in the coal seam.
The utility model is realized by following technical scheme, a kind of km borer drill rod fishing device, structure comprise help pull a cart, overcoat, interior cover, help pull a cart and the overcoat clamping, outer casing inner wall is a tapered slope, outer wall of inside race is a taper surface, outside helping pull a cart, is provided with draw ring.
Use principle, the drill rod end of exposing in coal group be inserted in successively help pull a cart, interior cover, overcoat, rib is made a call to two anchor poles and is cooperated 5 tons or 10 tons of chain slings to be connected with two draw rings of helping pull a cart to spur drilling rod over there then.The frictional force of cover and drilling rod makes the relative direction displacement of the overcoat and the interior cover conical surface, thereby the interior cover and the drilling rod that drag for tool is held tightly in utilizing, and pulling force is beaten more, and the power of holding tightly of generation is also big more, utilizes the chain sling rod pulling at last.
The utility model is simple in structure, and is reasonable in design, salvages effectively, is mainly used in to salvage to fall into and the drilling rod of in time not salvaging, the environment that the drilling rod of exposing at digging laneway can't adopt rig to salvage in the coal seam.Can practice thrift a large amount of equipment funds for coal mining enterprise.
Description of drawings
Fig. 1 is the structural representation of the utility model
Among the figure: cover, 5-slide fastener, 6-help pull a cart in 1-drilling rod, 2-draw ring, 3-overcoat, the 4-.
The specific embodiment
Meaning as shown in Figure 1, a kind of km borer drill rod fishing device, structure comprise help pull a cart 6, overcoat 3, interior cover 4, help pull a cart 6 with overcoat 3 clampings, overcoat 3 inwalls are tapered slope, interior cover 4 outer walls are taper surface, are provided with draw ring 2 outside 6 helping pull a cart.Cover 4 is made up of the butt joint of three part arc-like sheets in described.After through slide fastener 5 drilling rod 1 being pulled out, oppositely knock overcoat, can overcoat, interior cover be separated.
