Abstract
The utility model discloses a drill pipe holder which comprises two forceps (1) of the holder, two forceps holder seats (2) of the holder, two connection rods (3) of the holder, two connecting levers (4) of the holder and an oil cylinder (5) of the holder. The middle portions of the two connecting levers (4) of the holder are hinged on a rack (6). The two forceps (1) of the holder, the two forceps holder seats (2) of the holder and two connection rods (3) of the holder are hinged at one ends of the two connecting levers (4) of the holder. The oil cylinder (5) of the holder is hinged at the other ends of the connecting levers (4) of the holder. The drill pipe holder is large in clamping force, simple in structure and reliable in performance.
Description
Technical field
The utility model relates to a kind of hydraulic rock drill carriage, particularly relates to a kind of hydraulic rock drill carriage card pricker device.
Background technology
Existing card pricker device structure such as Fig. 1, by card pricker device clamp, card pricker device clamp seat, card pricker device connecting rod, card pricker device connecting lever and card pricker device oil cylinder, card pricker device connecting lever one end and frame are hinged, the other end is hinged with card pricker device oil cylinder, card pricker device clamp, card pricker device clamp seat and card pricker device rod hinge connection realize that by the contraction that blocks pricker device oil cylinder card pricker device clamp is to the clamping of drilling rod at the middle part of card pricker device connecting lever.The shortcoming of existing card pricker device: clamping force is not enough.
The utility model content
Technical problem to be solved in the utility model provides the large drilling rod card pricker device of a kind of clamping force.
In order to solve the problems of the technologies described above, the drilling rod card pricker device that the utility model provides, comprise two card pricker device clamps, two card pricker device clamp seats, two card pricker device connecting rods, two card pricker device connecting levers and a card pricker device oil cylinder, the middle part of two described card pricker device connecting levers is hinged on the frame, two described card pricker device clamps, two described card pricker device clamp seats and two described card pricker device rod hinge connections are at an end of two described card pricker device connecting levers, and described card pricker device oil cylinder is hinged on the other end of two described card pricker device connecting levers.
The hinge of described card pricker device oil cylinder and described card pricker device connecting lever arrives the distance of the hinge of described card pricker device connecting lever and described frame greater than the hinge of described card pricker device connecting rod and described card pricker device connecting lever to the distance of the hinge of described card pricker device connecting lever and described frame.
Adopt the drilling rod card pricker device of technique scheme, blocking the link position that changes each component under the substantially constant condition of pricker device appearance and size, increase clamping force.When hydraulic oil enters card pricker device oil cylinder, the elongation of card pricker device oil cylinder, card pricker device connecting lever is rotated around the hinge that fixed point namely blocks pricker device connecting lever and frame, drive two card pricker device clamps and move to by-level, thereby realize blocking pricker device chucking by card pricker device connecting rod, card pricker device clamp seat.Because the hinge of card pricker device oil cylinder and card pricker device connecting lever arrives the distance of the hinge of card pricker device connecting lever and frame arrives the hinge of card pricker device connecting lever and frame greater than the hinge of card pricker device connecting rod and card pricker device connecting lever distance, realize large clamping force, make drilling rod be more prone to from adapter sleeve, screw out.
In sum, the utility model is that a kind of clamping force is large and simple in structure, the drilling rod card pricker device of dependable performance.
Description of drawings
Fig. 1 is existing drilling rod card pricker device structural representation.
Fig. 2 is the structural representation of drilling rod card pricker device of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Existing card pricker device structure such as Fig. 1, by card pricker device clamp, card pricker device clamp seat, card pricker device connecting rod, card pricker device connecting lever and card pricker device oil cylinder, card pricker device connecting lever one end and frame are hinged, the other end is hinged with card pricker device oil cylinder, card pricker device clamp, card pricker device clamp seat and card pricker device rod hinge connection realize that by the contraction that blocks pricker device oil cylinder card pricker device clamp is to the clamping of drilling rod at the middle part of card pricker device connecting lever.The shortcoming of existing card pricker device: clamping force is not enough.
Referring to Fig. 2, the middle part of two card pricker device connecting levers 4 is hinged on the frame 6, two card pricker device clamps 1, two card pricker device clamp seats 2 and two card pricker device connecting rods 3 are hinged on an end of two card pricker device connecting levers 4, card pricker device oil cylinder 5 is hinged on the other end of two card pricker device connecting levers 4, the hinge of card pricker device oil cylinder 5 and card pricker device connecting lever 4 to the distance of card pricker device connecting lever 4 and the hinge of frame 6 greater than the hinge of card pricker device connecting rod 3 and card pricker device connecting lever 4 to the distance of card pricker device connecting lever 4 with the hinge of frame 6.
Referring to figure, 1 and Fig. 2, under the substantially constant condition of card pricker device appearance and size, change the link position of each component, increase clamping force.When hydraulic oil enters card pricker device oil cylinder 5,5 elongations of card pricker device oil cylinder, make card pricker device connecting lever 4 namely block the hinge rotation of pricker device connecting lever 4 and frame 6 around fixed point, drive two card pricker device clamps 1 by card pricker device connecting rod 3, card pricker device clamp seat 2 and move to by-level, thereby realize card pricker device chucking.Since the hinge of card pricker device oil cylinder 5 and card pricker device connecting lever 4 to the distance of card pricker device connecting lever 4 and the hinge of frame 6 greater than the hinge of card pricker device connecting rod 3 and card pricker device connecting lever 4 to the distance of card pricker device connecting lever 4 with the hinge of frame 6, realize large clamping force, make drilling rod be more prone to from adapter sleeve, screw out.
