Description

Cork extractor

Technical Field

The invention relates to a cork extractor.

Background

In the ship construction process, wooden plugs are needed to be used in many places, such as the pipe orifice sealing protection of some casing pipes and the floor drain orifice protection. Sometimes, however, the wooden plug is tightly hammered or the wooden plug is small in size and is retracted into the nozzle, so that the wooden plug is difficult to remove, and the wooden plug is broken and falls into the pipe by carelessness.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide the cork extractor which is simple in structure and convenient to carry and use. The efficiency of constructor get the wooden plug is greatly improved, the quality risk that the wooden plug breaks and gets into the pipeline has been avoided simultaneously.

In order to achieve the purpose, the technical scheme of the invention is to design a cork extractor which comprises a stepped cylindrical bolt seat, wherein the bolt seat is provided with a screw hole, a wood screw which is matched with the screw hole and used for connecting a cork with the bolt seat is arranged, the bolt seat is connected with a screw rod, the screw rod is provided with a ram in a sliding manner, and the screw rod is also provided with a limiting piece of the ram. The tool is fixed on the wooden plug by a wood screw, and the wooden plug is pulled out by utilizing the principle of a pin puller. The outer diameter of the bolt seat is phi 50 (unit: mm), and the matching center distance phi 34 wood screw holes are 4-phi 5; a screw rod M12 x 200 with two 30 threads; ram phi 60 phi 12.5 phi 80.

The screw rod is provided with external threads at two ends, the middle part of the bolt seat is provided with an internal thread hole matched with the external threads at one end of the screw rod, and the limiting part is a nut connected to the end part of the screw rod in a threaded connection mode; the ram slides on the portion of the screw between the two threaded sections of the screw.

The further technical scheme is that four screw holes are arranged and are arranged in an annular array by taking the center of the bolt seat.

The further technical scheme is that a fuel injection mechanism is hung on the side face of the large-size end of the bolt seat, and the fuel injection mechanism is connected with the hammer through a linkage rope.

The oil injection mechanism comprises an oil storage rubber bag, one end of the oil storage rubber bag is communicated with a rubber oil injection nozzle, a clip or a hook fixedly connected to the outer surface of the sleeve and the like is matched with the extractor, the clip is used for clamping the rubber oil injection nozzle, and the hook is used for hooking the rubber oil injection nozzle; the oil injection mechanism further comprises a first clamping rod fixedly connected to the bolt seat, a second clamping rod is hinged to the first clamping rod, a hinge point is located in the middle of the first clamping rod, the first clamping rod is identical to the second clamping rod in size and specification, the hinge point is also located in the middle of the second clamping rod, the portions, close to the bolt seat, of the first clamping rod and the second clamping rod are fixedly connected with pressure springs used for keeping the first clamping rod and the second clamping rod away from each other, the portion, far away from the bolt seat, of the second clamping rod is fixedly connected with a linkage rope, and the other end of the linkage rope is fixedly connected to the striker. Therefore, when the ram is pulled to enable the bolt seat to take the wooden plug out, the oil storage rubber bag can be clamped by the first clamping rod and the second clamping rod which are similar to a scissors structure, and a small amount of oil is sprayed on the wooden plug and the inner wall of the pipe when the wooden plug is pulled outwards, so that the lubricating effect is achieved, the wooden plug is convenient to take, and the labor intensity of workers for taking the wooden plug is reduced; once the wooden plug is taken out, the first clamping rod is far away from the oil storage rubber bag along with the bolt seat, oil can not be taken out any more, the clamp is loosened after the wooden plug is taken out, or the oil storage rubber bag is taken back from the hook and is hung on the wooden plug extractor again for taking out the wooden plug in the next pipe (the more preferable scheme is that the clamp is not fixed on the outer wall of the pipe but hung on a hook on the outer wall of the pipe, so that the clamp is taken off from the hook after use for subsequent continuous use, and the only beauty defect is that the scheme of the invention needs to weld a hook for hanging the clamp on the outer wall of the pipe at the same time of inserting the wooden plug).

The invention has the advantages and beneficial effects that: simple structure, convenient carrying and use. The efficiency of constructor get the wooden plug is greatly improved, and cooperation electric bolt sword availability factor is higher, has avoided the wooden plug to break the quality risk that gets into the pipeline simultaneously. When the ram hammer is pulled to enable the bolt seat to take the wooden plug out, the oil storage rubber bag can be clamped by the first clamping rod and the second clamping rod which are similar to a scissors structure, so that a small amount of oil is sprayed on the wooden plug and the inner wall of the pipe when the wooden plug is pulled outwards, a lubricating effect is achieved, the wooden plug is convenient to take, and the labor intensity of workers for taking the wooden plug is reduced; and once the wooden plug is taken out, the first clamping rod is far away from the oil storage rubber bag along with the bolt seat, oil can not be taken out any more, and after the wooden plug is taken out, the clamp is loosened or the oil storage rubber bag is taken back from the hook and hung on the wooden plug extractor again for taking out the wooden plug in the next pipe.
