Abstract

The invention relates to a quick-disassembly type drilling machine clamp holder. The q quick-disassembly type drilling machine clamp holder comprises clamping heads, drawbars, a pin shaft, a positioning screw and a base. The two clamping heads are arranged in a left-right opposite mode; both sides of the lower portions of the clamping heads are penetrated by the pin shaft in the front-back direction, hinged to a slot of the base, fixed through a nut and positioned through the positioning screw and the upper portions of the clamping heads are penetrated by two groups of the drawbars and fixed by nuts to compose a complete clamp holder. The clamping tile and the connecting rod of each clamping head are provided with a male T-type connecting sliding groove and a female T-type connecting sliding groove respectively; a baffle is fixed onto a front cover through a bolt to avoid deviation of the clamping tiles; when needing to disassembling the clamping tiles, a user simply needs to remove the bolt and the baffle; when the positioning screw and the nuts on the drawbars are released, the two clamping heads can horizontally slide outwards along groove-type holes for separation and then rotate outwards along the pin shaft, so that replacement and maintenance of the clamping tiles can be facilitated.

Description

Quick reassembling type drilling machine clamp holder

Technical field

The invention belongs to the clamper in application boring mechanic equipment technical field, particularly a kind of quick reassembling type drilling machine clamp holder.

Background technology

Boring mechanic equipment (abbreviation rig) is to be mainly used in colliery down hole drill, hydroelectric project probing, the Special drilling equipment of dam, bridge, tunnel basis drilled grout hole etc.Clamper is the important spare part of drilling tool in rig clamping hole, is used in conjunction with and realizes machinery and twist, unload drilling rod with chuck, prevents drilling tool slippage in hole.Clamper is arranged on the front end of rig drilling cramp.

Underground drill rig clamper mainly contains normally closed type, open in usual and this three types of combined type at present.The clamper of existing type, as name is called No. 201020112404.7 Chinese utility model patents of " a kind of open-top composite clamp holder ", its structure adopts open-top both sides to be arranged symmetrically with, two master cylinders are arranged symmetrically in the two ends at clamper center, the lower end of two master cylinders is connected with the sleeve being arranged on base, upper end is held with rotating upper connecting rod. and the master cylinder at two ends, slips, main oil cylinder piston, dish spring, fore-set, auxiliary oil cylinder piston, auxiliary oil cylinder conspire to create a cramping body, then the cramping body at two ends are coupled together with long adjusting yoke.

Because this combined type clamper is subject to structural limitations, have the following disadvantages:

1. in drilling operation, fast dismounting slips, because the effect of disc spring force cannot be taken out slips, needs entirety decomposition to change, and wastes time and energy;

2. in drilling operation, can not convenient replacing dish spring etc. consumable accessory, need entirety to decompose and could change, waste time and energy.

3. transferring before particle size drilling tool, clamper can only entirety overturning forward, and upset weight is large, and not too convenient.

In drilling machine construction process, after boring moulding, do not carry out aperture processing when shift position at rig, now need clamper to remove, then extra heavy pipe is put into hole.Use open clamper of the present invention, time that can free removal clamper, as long as take down the pull bar on clamping head, upset clamping head just can carry out aperture processing.

Summary of the invention

In order to solve the problems referred to above that exist in the prior art, the invention provides a kind of quick reassembling type clamper, to improve the maintainability of rig, improve the service efficiency of rig.

For achieving the above object, the technical solution used in the present invention is:

Quick reassembling type drilling machine clamp holder, comprises clamping head, pull bar, bearing pin, dog screw and base.Two clamping head left and right positioned opposite, both sides, bottom are fixed bearing pin fore-and-aft direction after through the slotted eye of clamping head and base respectively with nut, and top is fixed with nut after passing two clamping heads with two groups of front and back pull bar, forms complete clamper.

As preferred version, described pull bar is provided with sleeve pipe outward, in the slotted eye of base, is provided with spacer.

As preferred version, in described clamping head, slips is socketed on coupling bar with T-shaped groove, baffle plate is fixed on protecgulum with bolt, and slips is not offset.

As preferred version, on the flange of described each clamping head, there are four earrings, with four pull bars and sleeve pipe, two clamping heads are relatively fixing.Each clamping head below have a relative earrings in a pair of front and back, be hinged in the relative slotted hole in a pair of front and back on base with bearing pin, spacer, locate with dog screw.Unclamp the nut on dog screw and pull bar, two clamping heads can separate along slide outside translation of slotted hole, then outwards to overturn around bearing pin.

As preferred version, the symmetrical cloth layout of described two clamping heads, the slotted hole on base four arms of angle is also arranged symmetrically with.Make like this parts of both sides there is interchangeability.

Advantage of the present invention and effect:

1, quick reassembling type drilling machine clamp holder of the present invention, provide one efficiently, easy-to-dismount maintenance condition, effectively improve capability in handling accident.Particularly power outage processing, to improve the maintainability of rig, improves the service efficiency of rig.

2, on slips and coupling bar, be designed with the T-shaped connection chute of male and female, utilize bolt that baffle plate is fixed on protecgulum, slips is not offset, while changing slips, only need remove bolt and baffle plate, reach quick dismounting slips, reduce labour intensity, simple to operate, improve probing operating efficiency.

3, clamping head translation outward, gets around drilling rod, and upset clamping head, reserves larger space, and the consumable accessorys such as convenient replacing dish spring, improve probing operating efficiency at the non-cutting time of shortening rig.
