Description

A kind of hydraulic elevator

Technical field

The utility model relates to a kind of suspender, especially a kind of hydraulic elevator for geological drilling equipment.

Background technique

Geological prospecting generally uses outer flush drill stem, and the prior art will screw on mushroom head on drilling rod when putting brill and be drawn with mentioning Device puts brill, or puts brill by artificial elevator.There need to be personnel to come at this traditional operating method aperture and boring tower quadruple board platform Unloading mushroom head is returned, hangs repeatedly and unloads elevator, very time and effort consuming.Sometimes it to propose brill efficiency, is needed at the top of each cylindrical drill bar One mushroom head is set, and mushroom head quantity increases, and increases construction cost, especially when using different drilling tools, different button-types, needs Process respective type mushroom head, increased costs it is more, non-cutting time is longer.In addition, now geological drilling based on deep hole, Operator can not unload elevator in the timely unloading mushroom head in aperture and extension when there is well kick, blowout, so as to cause being easy to appear Safety accident, whole drilling efficiency are low.

Utility model content

The purpose of this utility model is that aiming at the disadvantages of the prior art, providing a kind of time saving, laborsaving, safety, low cost And it is suitable for the hydraulic elevator of a variety of drilling rods

Problem described in the utility model is solved with following technical proposals:

A kind of hydraulic elevator, including flap seat, chassis, control panel, oil cylinder and one group of slips, the chassis are fixed under flap seat Portion, control panel are located at flap seat top, and vertically-mounted oil cylinder bottom is fixed on chassis, and cylinder piston rod connects control panel, control Disk processed is equipped with one group of radial groove, and flap seat is equipped with up big and down small conical bore, and one group of slips is located in conical bore, each slips Outer wall is bonded with the matching of the conical bore of flap seat, and each slips inner wall is arc surface, is equipped with guide blot at the top of each slips, is respectively oriented to spiral shell Bolt is each passed through corresponding guide chute, and the inner wall of each slips is equipped with spring groove, is placed with spring in spring groove.

Above-mentioned hydraulic elevator further includes lifting lug, and two lifting lugs are symmetrically fixed on flap seat two sides, and each lifting lug hangs slot equipped with U-shaped, Pin shaft passes through the opening for hanging slot, by closure of openings.

Above-mentioned hydraulic elevator, the inner wall of the slips are equipped with gear piece slot, gear piece slot lower part soldering sector baffle, in gear piece slot Slips gear piece is installed, slips gear piece inner wall is equipped with groove, and slips gear piece bottom presses fan-shaped baffle.

Above-mentioned hydraulic elevator, the taper of the flap seat conical bore are 18 ° -22 °.

Above-mentioned hydraulic elevator, the number of one group of slips are 3-6 block.

Above-mentioned hydraulic elevator, the chassis lower part are equipped with taper sheath.

Above-mentioned hydraulic elevator at least installs one piece of slips gear piece on every piece of slips.

The utility model solve the problems, such as that existing geological drilling equipment makes a trip time and effort consuming and specially design one Kind hydraulic elevator.The hydraulic elevator substitutes manual operation with hydraulic power, is passed through using inclined plane force increasing principle vertically disposed Cylinder piston rod movement drives slips clamping and release, will act on the normal pressure of the slips body behind conical surface by Orthogonal Decomposition, obtains The frictional force between drilling rod is generated to the normal pressure for acting on drilling rod surface and clamps drilling rod, and that realizes drilling rod puts brill.Using The utility model can abandon mushroom head elevator, can be substantially while easy to operate reliable reducing labor intensity of workers Degree reduces overhead time.Work safety, stabilization, reliable with easy to operate, construction cost is low, and drilling efficiency is high, applicable The features such as range is wide.

Specific embodiment

Referring to Fig. 1-Fig. 3, the utility model includes lifting lug 1, flap seat 2, chassis 8, control panel 6, oil cylinder 7 and one group of slips. At lifting lug setting two, two lifting lugs are symmetrically fixed on flap seat two sides, and each lifting lug, which is equipped with, hangs slot 1-1 for hang hanging ring, and hanging slot is Lateral U-lag.Pin shaft 10 passes through the opening for hanging slot, by closure of openings.By pin shaft after hanging ring 13 is linked into and hangs slot when use Insertion, hanging ring falls off when preventing from putting brill.Chassis is fixed on flap seat lower part, and control panel is arranged on flap seat top.Vertically-mounted The bottom of oil cylinder 7 is fixed on chassis, and to guarantee that stress balance, oil cylinder are equipped with two sets, it is same that two sets of oil cylinders are located at flap seat The both ends of diameter extended line.Each cylinder piston rod is separately connected control panel, and control panel is equipped with one group of radial groove 6-1.Flap seat Equipped with up big and down small conical bore, one group of slips is mounted in conical bore, and the outer wall of each slips 4 is to match with the conical bore of flap seat The arc conical surface of fitting, each slips inner wall are arc surface, its inner wall constitutes and mention 14 diameter of drilling rod of brill after one group of slips pairing Matched cylindrical surface.The taper of flap seat conical bore, which is 18 ° -22 °, to be advisable.Guide blot 5, each guide blot are screwed at the top of each slips It is each passed through corresponding guide chute, the inner wall of each slips is equipped with spring groove 4-1, spring 3 is equipped in spring groove, and spring uses Circular open spring.It is equipped with taper sheath 9 in chassis lower part, taper sheath is used to enter for drill-pipe stand elevator and plays guiding work With.

Referring to Fig. 4, Fig. 5, to improve the frictional force between slips and drilling rod, gear piece slot 4-2, tooth are equipped in the inner wall of slips Film trap lower part soldering sector baffle 11, gear piece slot is interior to install slips gear piece 12, and slips gear piece is made of wear-resistant material, slips tooth Piece inner wall is equipped with groove, and slips gear piece bottom presses fan-shaped baffle.One piece of slips gear piece is at least installed, diagram is real on every piece of slips It applies and two slips gear piece blocks is housed on every piece of slips in example.Split assembled structure between slips gear piece and slips is convenient to abrasion Slips gear piece is replaced.The number of one group of slips is 3-6 block, and the number of slips is four pieces in illustrated embodiment.Pass through replacement What slips can be applicable in different-diameter drilling rod puts brill.

The course of work of the utility model is as follows: when drilling rod enters elevator, the piston rod of two oil cylinders stretches out, in control panel It moves, each slips under the action of the spring, radially expands, slips while moving up with control panel along the guide groove in control panel After radial opening completely, diameter of bore substantially exceeds clamped drilling rod outer diameter, guarantees that clamped drilling rod can smoothly enter into elevator；It will hang Ring hangs over the hanging on slot of flap seat two sides, and the pin shaft hole on lifting lug is inserted into pin shaft, and two Vertical Cylinders piston rods retract, in control panel Under the action of slips it is radially contracted, the circular cone internal surface of hole of the slips back side and flap seat is taper-face contact, and flap seat inner surface produces at this time Raw positive pressure is acted between the normal pressure and drilling rod of drilling rod radial direction in the slips back side by the Orthogonal Decomposition of power Frictional force is greater than (or being equal to) drilling rod gravity, achievees the purpose that clamping drilling rod mentions brill.And drilling rod is heavier, the power of slips holding drill pipe It is bigger, folder it is tighter.
