Abstract
The utility model discloses a drill pipe puller of a raiser borer which is different in that two ends of a drill pipe fixing clamp (1) are respectively connected with two connecting rods (2); the two connecting rods (2) are connected through a crossbeam (4); and a pulling rod (3) is fixed at the middle position of the connecting crossbeam (4). The drill pipe puller is simple and convenient to operate and firm and durable. The drill pipe puller improves the construction efficiency of the borer, reduces the work intensity of the workers and is particularly suitable for pulling up a broken drill pipe of a raise borer in a metal mine.
Description
Technical field:
The utility model relates to a kind of drilling rod driver-extractor, and particularly a kind of metal mine extracts the drilling rod driver-extractor that raise boring machine fracture drilling rod is used.
Background technology:
At present, raise boring machine is in the process of construction drop shaft, because rock is harder, courtyard length is longer, the impaired phenomenon of drilling rod silk mouth occurs, cause rig can't continue construction, the appearance of this kind phenomenon need propose boring so that the drilling rod that more renews with damaging drilling rod, but drilling rod weight is too big, and manpower can't be operated at all.
Summary of the invention:
It is a kind of simple, easy to use that the purpose of this utility model will provide exactly, can in time change a kind of raise boring machine drilling rod driver-extractor that damages drilling rod fast.
The purpose of this utility model is achieved in that a kind of raise boring machine drilling rod driver-extractor, it is characterized in that the fixing pincers of drilling rod (1) two ends link to each other with the lower end of two connecting rods (2) respectively, the upper end of two connecting rods (2) respectively be connected crossbeam (4) and link to each other, extract bar (3) and be fixedly connected on and connect crossbeam (4) centre position.
The utility model compared with prior art has the following advantages:
Owing to adopted the fixing pincers of drilling rod (1) two ends to link to each other with the lower end of two connecting rods (2) respectively, the upper end of two connecting rods (2) respectively be connected crossbeam (4) and link to each other, extract bar (3) and be fixedly connected on the form of structure that connects crossbeam (4) centre position, thereby it is simple to operation, durable, improve drilling machine construction efficient, reduced labor strength.
Description of drawings:
Figure: be concrete structure schematic diagram of the present utility model
1, the fixing pincers 2 of drilling rod, connecting rod 3, extraction bar 4, connection crossbeam
The specific embodiment:
Connecting rod (2) adopts the round steel of diameter 30MM to make, length is 0.3 meter, extracting bar (3) adopts the round steel of diameter 36MM to make, length is 1.3 meters, the fixing pincers of drilling rod (1) two ends link to each other with the lower end of two connecting rods (2) respectively, the upper end of two connecting rods (2) respectively be connected crossbeam (4) and link to each other, extract bar (3) and be fixedly connected on and connect crossbeam (4) centre position.
During use, on earlier that the fixing pincers of drilling rod (1) are the firm drilling rod that is fixed on fracture, then connecting rod (2) is connected on the fixing pincers of drilling rod (1), connecting rod (2) connects together by connecting crossbeam (4), is fixed on the centre position that connects crossbeam (4) will extracting bar (3), is connected on the raise boring machine hydraulic motor on will extracting bar at last, the rig running, hydraulic motor drives and extracts bar (3), and with the drilling rod proposition boring of fracture, the drilling rod that more renews then gets final product.
Claims (1)
1. a raise boring machine drilling rod driver-extractor is characterized in that the fixing pincers of drilling rod (1) two ends link to each other with two connecting rods (2) respectively, and two connecting rods (2) connect together by connecting crossbeam (4), extract bar (3) and are fixed on connection crossbeam (4) centre position.
