Abstract
The utility model discloses a power assisting device of power catwalk lifting. The power assisting device of the power catwalk lifting is composed of a tackle, a jackstay and a double-acting hydraulic cylinder. The tackle is composed of an idler wheel assembly, an idler wheel base, a jackstay base, a frame and a hydraulic cylinder base. The jackstay base and the hydraulic cylinder base are respectively welded on the frame, the idler wheel base is welded on the frame, the double-acting hydraulic cylinder is hinged on the hydraulic cylinder base, and a piston rod of the double-acting hydraulic cylinder is hinged with the jackstay rod. A front idler wheel and a rear idler wheel can freely roll in a platform guide rail, transition stability is good, a positioning plate does not need to be used for positioning and positioning impact is eliminated. Due to the specific design of the idler wheels, the service life is longer, bearing capacity is larger, and safety is better. The double-acting hydraulic cylinder is respectively hinged with the hydraulic cylinder base and the jackstay of the tackle, and plays a role in buffering of power assisting so that the lifting process is continuous, stable and non-impact. By adjusting the stroke of the hydraulic cylinder, a space pose of a lifting system can be controlled, and operation is convenient by adjustment of the angle of a drill stand on a drill rod.
Description
Technical field

Summary of the invention
The purpose of this utility model is to provide a kind of dynamic catwalk and promotes booster.
The utility model is to consist of coaster, strut and double acting hydraulic cylinder, described coaster is comprised of roll wheel assembly, roller mount, strut socket, vehicle frame and hydraulic cylinder seat, strut socket and hydraulic cylinder seat are welded on respectively on vehicle frame, roller mount is welded on vehicle frame, double acting hydraulic cylinder is hinged on the hydraulic cylinder seat, and piston rod and the strut of double acting hydraulic cylinder are hinged, described roll wheel assembly is to consist of roller shaft, roller, roller end cap, the first sealing ring, circlip, roller end cap, sealing ring, lubricating cup, nut, stop washer, the first rolling bearing, roller axle sleeve, roller spacer, the second rolling bearing, the second sealing ring, roller bearing pin clamp, packing ring and bolt, roller shaft is set in roller mount, roller bearing pin clamp is plugged in the end of roller shaft, roller bearing pin clamp, with packing ring and being bolted on roller mount, is fixed together roller shaft and roller mount, sheathed the first rolling bearing of the revealed section of roller shaft and the second rolling bearing, sheathed roller axle sleeve on roller shaft between the first rolling bearing and the second rolling bearing, be separated with the roller spacer between between the first rolling bearing and the second rolling bearing, nut is spirally connected on roller shaft outside the first rolling bearing, the inboard sandwiched stop washer of nut, the outer roller shaft of the nut roller end cap that is spirally connected, the outer end of roller shaft plugs lubricating cup, lubricating cup is by oil duct and roller axle sleeve, the first rolling bearing, roller spacer and the second rolling bearing are communicated with, the outer sheathed roller of the first rolling bearing and the second rolling bearing, between roller end cap and roller shaft, with the first sealing ring, seal, between roller end cap and roller, with circlip, seal, between the other end of roller and roller shaft, with the second sealing ring, seal.
The course of work of the present utility model and principle are:
Roller is arranged on the apparatus for suspension two ends, and when the lifting slideway moves up along ramp, roller is Free-rolling in orbit, makes coaster do translational motion; Double acting hydraulic cylinder is hinged on the hydraulic cylinder seat, and piston rod and strut are hinged, and the hydraulic cylinder action realizes steadily propping and falling with strut.In lifting process, by controlling the stroke of double acting hydraulic cylinder, can play the effect of force-aid buffering.By adjusting the stroke of double acting hydraulic cylinder, can control the spatial pose of hoisting system in addition, adjust the angle of rig floor on drilling rod.Strut one end and strut socket are hinged, and in lifting process, strut will rotate centered by the strut socket hinged place.
The beneficial effects of the utility model:
Front and rear rolling wheel of the present utility model can be in platform rail Free-rolling, the translation stationarity is good, without the location-plate location, has eliminated location and has impacted; The particular design of pair roller, make its application life higher, supporting capacity larger, safety is better.Double acting hydraulic cylinder is hinged with hydraulic cylinder seat and the strut of coaster respectively, plays the effect of force-aid buffering, makes the lifting process continuous and stable, without impacting.By adjusting the stroke of hydraulic cylinder, can control the spatial pose of hoisting system, adjust the angle of rig floor on drilling rod, easy to operate.
