Description

Intracavity hoisting device

Technical Field

The utility model relates to a lifting device technical field, concretely relates to intracavity hoist device.

Background

The existing internal-supporting type lifting appliance comprises a planetary gear type lifting appliance, an internal-supporting type stator core lifting appliance, an internal-supporting type workpiece processing clamp, an internal-supporting type vertical shaft pipeline lifting appliance and the like. The planet gear type lifting appliance drives the planet gear, the supporting claw and the inner wall of the hole of the component to expand tightly for lifting by utilizing the principle of the planet gear and rotating the sun gear, and the planet gear of the lifting appliance has enough space and cannot be used when the component with small aperture is lifted; the internally-supported workpiece machining clamp is used for fixing a workpiece by utilizing a hydraulic or pneumatic supporting claw and then machining, and has the advantages of more required auxiliary equipment, inflexible movement and complex operation; the internal supporting type stator core lifting appliance and the internal supporting type vertical shaft pipeline lifting appliance are special tools used in special operation, and the basic principle is that supporting claws are opened through supporting rod transmission, and expanding iron core holes or pipe walls are hoisted.

The utility model discloses a pile extractor is disclosed in prior art bulletin number CN108104122A, through setting up first flat board, there is first dead lever on the terminal surface under the first flat board, it has the connecting rod to run through on the first flat board, there is the cohesion device connecting rod top, there is the fixed plate on the first flat board, there is pressure device on the fixed plate, there are two sleeves in the below of depression bar, there is the chucking piece in the sleeve, therefore, the clothes hanger is strong in practicability, can reach the effect with less power and can extract the stake many times, but overall structure is complicated, be not convenient for production and transportation, and can't the fast switch over use to the stake of different models, the operation is complicated, low applicability.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that to prior art not enough, the purpose is solved intracavity hoist device structure complicacy, and the problem that the suitability is low provides an intracavity hoist device.

The utility model provides an above-mentioned technical problem's technical scheme as follows: the intracavity hoisting device is characterized by comprising a hoisting rod and a tensioning sleeve, wherein the tensioning sleeve consists of more than two tensioning petals, the lower end of the hoisting rod is connected with a taper body in a detachable mode, the tensioning sleeve is sleeved on the hoisting rod and is not connected with the hoisting rod, and the outer wall of the tensioning sleeve is provided with an anti-skid layer.

Furthermore, the tensioning sleeve is fixedly connected with a using handle, and a clamping groove for clamping the workpiece is formed in the handle.

Furthermore, the top end of the suspender is fixedly connected with a hoisting ring.

Further, the inner diameter of the tension sleeve is smaller than the maximum radius of the taper body.

Furthermore, a plurality of groups of anti-skid grooves are formed in the anti-skid layer.

The utility model has the advantages that: the utility model discloses a set up including the jib and the tight cover that rises, the tight cover that rises comprises the tight lamella that rises more than two, the jib lower extreme is connected with the tapering body through can dismantling the mode, the tight cover that rises embolias on the jib and not with jib interconnect, the tight cover outer wall that rises is equipped with the skid resistant course. The expansion sleeve is arranged by an operator, the hanging rod rises, the taper body supports the expansion sleeve, the anti-slip layer and the inner wall of the workpiece interact with each other to prevent the workpiece from sliding downwards, the whole structure is simple, the production, the installation and the transportation are convenient, and the working efficiency and the application range are improved.
