Abstract

The utility model relates to a novel mouse hole device. According to the novel mouse hole device, a sludge discharge channel is arranged on the bottom of an outer pipe, a spring seat is arranged in a cavity on the bottom of the outer pipe, and a spring and a buffering seat are arranged on the spring seat in a connecting mode. The novel mouse hole device is simple in structure, convenient to assemble and disassemble, and easy to machine. Compared with the prior art, the novel mouse hole device has the advantages that discharging of slurry left in a drill stem is benefited, a buffering effect is played on the drill stem, and screw threads of the drill stem is protected beneficially.

Description

Novel mouse hole device

Technical field

This practical invention relates to the matching component of the large-scale open-air operation equipment such as a kind of oil-well rig, and a kind of novel rig floor is deposited the device of drilling rod temporarily specifically.

Background technology

Modern drilling has proposed more and more higher requirement to drilling efficiency, how within the shortest time, to finish effective drilling depth, people have invented the device of temporarily depositing drilling rod on table top, saved like this time that lifts drilling rod under the table top, old-fashioned mouse hole pipe is the steel pipe of a simple sealed bottom, and it has the following disadvantages:

1. sealed bottom is unfavorable for the eliminating of residual slip in the drilling rod.

2. put drilling rod mouse hole bottom at every turn the drill rod end screw thread is had impact failure.

The utility model content

The present invention is intended to for above deficiency, provides a kind of and need not to lift, easy to operate and can be with the convenient device of slurry transportation to the mud receiving system.

The concrete technical scheme of the utility model is: comprise outer tube, its bottom is provided with the spoil disposal passage, and is provided with spring base in the described outer tube bottom cavity, connection spring and buffing pad on it.

Described buffing pad comprise holder and in the wooden unit inlayed.

Described outer tube top also is provided with the mouse hole lid.

Also be provided with hole for hoist on the described outer tube.

This novel mouse hole is compared with conventional art, has following remarkable advantage:

1. be conducive to the drainage of residual slip in the drilling rod.

2. drilling rod is played cushioning effect, be beneficial to the protection drilling rod thread.

3. end face mouse hole lid is consistent with table surface height, has saved table space, makes things convenient for the operation of table top main equipment to use.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is left view of the present utility model;

Fig. 3 is right view of the present utility model;

Wherein: 1, junction plate, 2, mouse hole lid, 3, seamless steel pipe, 4, hole for hoist, 5, screw, 6, the buffering wooden unit, 7, the wooden unit holder, 8, spring, 9, mudhole, 10, spring base

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Referring to Fig. 1-3, a kind of novel mouse hole device, the inwall welding spring base 10 of end seamless steel pipe 3(outer tube), described spring base comprises the disk on the cross hang of interconnective bottom and top, and disk is provided with mudhole 9, and consisted of the spoil disposal passage by the space of mudhole 9 and cross hang, be beneficial to the drainage of the inner residual slip of drilling rod; On the spring base 10 successively mounting spring 8,, in the wooden unit holder 7 by screws 5 fixing buffering wooden units 6; And the integrated device that spring 8, wooden unit holder 7 and buffering wooden unit 6 form can be free to slide in seamless steel pipe 3; Steel pipe top is processed with hole for hoist 4, the top is provided with mouse hole lid 2.

When drilling rod was put into mouse hole, wooden unit holder 7 along seamless steel pipe 3 inwall down slidings, played buffer protection function by 8 pairs of drilling rods of Compress Spring under the drilling rod Action of Gravity Field; After drilling rod took out, wooden unit holder 7 set back under spring 8 effects; Four mudholes 9 are opened in the mouse hole bottom, are beneficial to the drainage of the inner residual slip of drilling rod, and mouse hole lid 2 plays preventing that the people from treading in the safety effect of rat hole accidentally topmost.

The above is preferred embodiment of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; might be to concrete size; perhaps partial structurtes go out some improvements and modifications, and these improvements and modifications also should be considered as protection domain of the present utility model.
