Abstract
The utility model relates to a hydraulic tongs lifting mechanism. The hydraulic tongs lifting mechanism is characterized by comprising racks, climbing gears, a hydraulic motor, a shaft coupler, worms and worm gears, wherein the two racks are symmetrically arranged at the two ends of a tongs body; the racks are vertical to the ground; the two racks are in contact with the two climbing gears respectively; the two climbing gears are meshed with the two worm gears respectively; the two worm gears are arranged on the two worms respectively; and the two worms are connected with the shaft coupler and the hydraulic motor respectively. Compared with the prior art, the hydraulic tongs lifting mechanism has the advantages that: 1), the hydraulic tongs lifting mechanism can lift or lower the hydraulic tongs body flexibly, so that a worker is not required to operate the hydraulic tongs from a near distance and the automatic level of petroleum drilling is improved; 2), a control part of the hydraulic motor of the hydraulic tongs lifting mechanism can be arranged on a control platform on site, so that labor is saved, the hydraulic tongs lifting mechanism is time-saving and labor-saving and the working efficiency is improved; and 3), the hydraulic tong lifting mechanism is simple in structure, convenient to use and reasonable in design, and the safety coefficient on the site of the petroleum drilling is effectively improved.
Description
Technical field
The utility model relates to a kind of lifting gear, particularly a kind of hydraulic tongs elevating mechanism.
Background technology
In petroleum drilling operation, hydraulic tongs is a drilling and repairing well rig tool commonly used, and the hydraulic tongs of situ of drilling well normally is hung in the top of well head with suspension hook; Since hydraulic tongs from great; Oscillatory is also big, so when needs use hydraulic tongs, need two workmans to control hydraulic tongs simultaneously; Some drawback below such operation exists: 1) operating time long, inefficiency; 2) labor strength is big; 3) operating personnel's closely operation, safety factor is low.
Therefore, need be a kind of simple in structure, easy to use when using the hydraulic tongs operation, the device that can increase work efficiency.
Summary of the invention
The purpose of the utility model provides a kind of hydraulic tongs elevating mechanism, and this apparatus structure is simple, reasonable in design, easy to use, can improve the operating efficiency of operation hydraulic tongs.
For realizing above-mentioned purpose, the utility model adopts following technical scheme to realize:
A kind of hydraulic tongs elevating mechanism is characterized in that, comprises tooth bar, the gear that climbs, hydraulic motor, shaft coupling, worm screw, worm gear; Article two, tooth bar is symmetricly set on the caliper two ends; And tooth bar setting perpendicular to the ground, two tooth bars contact with two gears that climb respectively, and two gears that climb mesh with two worm gears respectively; Two worm gears are located at respectively on two worm screws, and two worm screws are connected with shaft coupling, hydraulic motor respectively.
Compared with prior art, the beneficial effect of the utility model is: 1) this device can improve the hydraulic tongs caliper or reduce flexibly, no longer needs the workman that hydraulic tongs is carried out in-plant operation, has improved the automatization level of oil drilling; 2) control section of the hydraulic motor of this device can be located on the on-the-spot controlling platform, has saved the labour, and time saving and energy saving, has improved operating efficiency; 3) this apparatus structure is simple, easy to use, reasonable in design, effectively raises the on-the-spot safety factor of oil drilling.

Among the figure: the 1-tooth bar 2-gear 3-hydraulic motor 4-shaft coupling 5-caliper 6-worm screw 7-worm gear that climbs
The specific embodiment
Describe in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
See Fig. 1, Fig. 2, Fig. 3; A kind of hydraulic tongs elevating mechanism comprises tooth bar 1, the gear 2 that climbs, hydraulic motor 3, shaft coupling 4, worm screw 6,7, two tooth bars 1 of worm gear be symmetricly set on caliper 5 two ends; And tooth bar 1 setting perpendicular to the ground; Article two, tooth bar 1 contacts with two gears 2 that climb respectively, and two gears 2 that climb mesh with two worm gears 7 respectively, and two worm gears 7 are located at respectively on two worm screws 6; Two worm screws 6 are connected with shaft coupling 4, hydraulic motor 3 respectively, and hydraulic motor 3 is directly controlled by console.
During this device busy; The staff directly sends instruction to hydraulic motor 3 at console; The rising of caliper 5 or corresponding the rotating of hydraulic motor 3 that descends, the rotating of hydraulic motor 3 drives worm screws 6 through shaft coupling 4 and rotates, and the rotation of worm screw 6 drives the rotation of worm gear 7; Worm gear 7 rotates the up-down of gear 2 on tooth bar 1 of climbing that drives with worm gear 7 engagements, and then realizes the up-down of caliper 5.
