Description

Hydraulic clamp holder

Technical Field

The utility model relates to the technical field of hydraulic clamps, in particular to a hydraulic clamp.

Background

Drilling mechanical equipment (a drilling machine for short) is special drilling equipment mainly used for underground drilling of coal mines, drilling of hydroelectric engineering, grouting and drilling of dams, bridges and tunnel foundations and the like. The holder is a part of the drilling machine for disassembling the drilling tool.

In the construction process of the drilling machine, after the drilling machine is drilled and formed, the orifice is processed when the drilling machine does not move, at the moment, the clamp holder needs to be detached, and then the thick pipe is placed into the hole. Users demand holders that are small, lightweight, and easy to maintain (particularly in the field).

At present, most of holders of an underground drill rig are larger and larger in disassembly torque, larger in size and heavier in weight, so that the drill rig is larger and larger, the weight is more than 200kg, the slips are not convenient to disassemble and assemble, the problems can be solved in the prior art, but the defects are more or less, and the requirements of the existing working conditions cannot be met

In view of the foregoing, there is a need for a hydraulic clamp that addresses the deficiencies in the prior art.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model provides a hydraulic clamp holder, which aims to solve the problems.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a hydraulic clamp holder, includes bottom plate, hydro-cylinder seat, spring, protects and just overlaps the clamp plate, protects just overlapping, slips axle, top cap, rand, slips, clamp plate, locating plate, the hydro-cylinder seat is through round pin hub connection in bottom plate, the clamp plate passes through bolt fixed connection in the hydro-cylinder seat, locating plate and top cap all pass through bolt fixed connection in the hydro-cylinder seat, the spring joint is in the rand, the rand passes through screw connection in slips.

Preferably, a plurality of first bosses for connecting the positioning plate and the top cover are fixedly arranged on two sides of the cylinder block.

Preferably, the positioning plate and the top cover are provided with a plurality of first concave platforms which are in adaptive connection with the first convex platforms.

Preferably, the inner walls of the positioning plate and the top cover are provided with second bosses for connecting the slip shaft.

Preferably, a plurality of second concave platforms are fixedly arranged at two ends of the slip shaft, and a plurality of slip grooves are further arranged in the middle of the slip shaft.

Preferably, the clamping ring is fixedly provided with a plurality of inclined T-shaped grooves.

The utility model has the beneficial effects that: when having the drilling rod, can dismantle after the release and protect positive cover clamp plate, protect positive cover, top cap, clamp plate, tap the rand, can change the slips that has worn and torn for convenient maintenance removes one of them round pin axle and can be greater than 90 angles with the upset of whole holder, so that the thick pipe is planted downtheholely, and it is very convenient to use, and structural design is simple reasonable, and the practicality is stronger, has certain use value and spreading value.

Drawings

FIG. 1 is a front cross-sectional view of the structure of the present invention.

FIG. 2 is a schematic side view of the structure of the present invention.

In the figure: 1-bottom plate, 2-oil cylinder seat, 3-spring, 4-protecting sleeve pressure plate, 5-protecting sleeve, 6-slip shaft, 7-top cover, 8-collar, 9-inclined backing plate, 10-slip, 11-pressure plate and 12-positioning plate.

Detailed Description

As shown in fig. 1 and 2, the hydraulic clamp holder comprises a bottom plate 1, a cylinder base 2, a spring 3, a sheath pressing plate 4, a sheath sleeve 5, a slip shaft 6, a top cover 7, a clamping ring 8, an inclined base plate 9, a slip 10, a slip 11 and a positioning plate 12, wherein the cylinder base 2 is connected to the bottom plate 1 through a pin shaft, the slip 11 is fixedly connected to the cylinder base 2 through a bolt, the positioning plate 12 and the top cover 7 are both fixedly connected to the cylinder base 2 through a bolt, the spring 3 is clamped to the clamping ring 8, and the clamping ring 9 is connected to the slip 10 through a screw.

Furthermore, two sides of the cylinder block 2 are respectively and fixedly provided with four first bosses for connecting the positioning plate 12 and the top cover 7.

Furthermore, the positioning plate 12 and the top cover 7 are respectively provided with four first concave platforms which are in adaptive connection with the first convex platforms.

Further, the inner walls of the positioning plate 12 and the top cover 7 are provided with five second bosses for connecting the slip shaft 6.

Furthermore, two ends of the slip shaft 6 are fixedly provided with four second concave tables, and the middle of the slip shaft 6 is also provided with five slip grooves.

Furthermore, five large-angle inclined T-shaped grooves are fixedly arranged on the retainer ring 8, so that the slips 17 on the inclined backing plate 9 in the grooves can be conveniently and quickly loosened from the drill rod.

The working principle of the utility model is as follows: when the hydraulic clamp holder is connected with hydraulic oil, the clamping ring 8 is pushed to move forwards under the action of the oil pressure, so that the slips 10 move towards the axial lead direction of the drill rod, and the drill rod is clamped; when the hydraulic oil of the hydraulic clamp holder is in a pressure relief state, the clamping ring 8 is rapidly pushed to move backwards under the action of the rectangular cylindrical spring 3, and the slips 10 on the inclined base plate 9 are driven to move towards the opposite direction of the axial lead of the drill rod through the five large-angle inclined T-shaped grooves of the clamping ring 8, so that the slips 10 are separated from the drill rod, and the drill rod is loosened.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
