Description
Technical field
The utility model relates to the automatic reciprocating walking power clamp of a kind of height adjustable, belongs to oil drilling machine field.
Background technology
Hydraulic power tongs realizes movement and the installation of Power Tong mostly by suspension apparatus and propelling movement cylinder when drilling and repairing well operation, because Power Tong volume is large, quality weight, moving or needing many people to operate in installation process, labour intensity is large, and the safety factor of workman is low.In addition, the narrow space of more existing offshore boring island, be not suitable for installing suspension apparatus, this hinders the use of hydraulic power tongs undoubtedly.A kind of new technical scheme is needed to solve above-mentioned technical problem.
Summary of the invention
The purpose of this utility model is to provide the automatic reciprocating walking power clamp of a kind of height adjustable, being moved forward and backward by mobile roof support of this Power Tong, and Power Tong freely can be elevated relative to drilling floor surface, can pass over well head and walk to rat hole mouth, do not need mobile cylinder and suspension apparatus, whole operation process can complete in one man operation, also can Long-distance Control complete, greatly reduce labour intensity, improve the safety factor of workman.
The technical solution adopted in the utility model is:
The automatic reciprocating walking power clamp of a kind of height adjustable, comprise hydraulic power tongs, described hydraulic power tongs comprises main pincers and back-up tong, described hydraulic power tongs hangs on mobile roof support, the bottom of described mobile roof support is equipped with walking track, described mobile roof support comprises outside framework part and inner frame part, and described inner frame part is connected with outside framework part with by hydraulic lift, and inner frame part can along the inner side oscilaltion of outside framework part.Described outer frame portion divides the bearing diagonal frame comprising two main backstops be arranged in parallel and two and be arranged in parallel, described main backstop and the bottom of bearing diagonal frame of homonymy are respectively arranged with the base be fixedly connected with track of walking, be provided with cross supporting frame between the bearing diagonal frame of between the main backstop of both sides and both sides, the chute for the oscilaltion of inner frame part is all left in the inner side of two main backstops.Described inner frame part comprises lifting support frame and suspension supporting frame, described suspension supporting frame is provided with multiple hanger bar for suspension hydraulic Power Tong.
Further, described base is provided with the hydraulic motor matched with track of walking.
Further, described mobile roof support is provided with hydraulic control device.
The utility model has the advantages that: moved forward and backward by mobile roof support, and Power Tong freely can be elevated relative to drilling floor surface, can pass over well head and walk to rat hole mouth, do not need mobile cylinder and suspension apparatus, whole operation process can complete in one man operation, also Long-distance Control can complete, greatly reduce labour intensity, improve the safety factor of workman; And the support frame structure adopted is simple, make and fast easy to assembly, hydraulic power tongs smooth running is reliable, bearing strength and precision high, may be used for drilling rod, oil pipe and sleeve pipe.
