Description
Technical field
The present invention relates to oil equipment field, specially a kind of hanging device for oil pipe.
Background technique
With China's rapid development of economy, energy shortages, environmental pollution and the contradiction of economic development become increasingly conspicuous, therefore
Country advocates environmental protection, economizing type and project with independent intellectual property rights.Into 21st century, national departments concerned is mentioned
A series of environmental protection measure new concepts such as environment, energy-saving and emission-reduction are protected out, simultaneously close off a collection of small scale, energy consumption height, environmental pollution
The medium-sized and small enterprises for being not suitable for continuing development such as big, promote national living environment energetically.Petroleum industry is the basic energy resource type of country
Enterprise, investment is big, reciprocation cycle is long, and many places remote area more fragile in environment is slightly polluted, could be by within decades
Gradually restore.Therefore, the protection environmental liability that oil play is born is just more great.
The cleaning oil pipe of oil well uses open at present, directly rinses by well, and before rinsing, it needs to lift in oil pipe
Onto well-washing truck, operated convenient for subsequent cleaning oil pipe.
In order to solve the problems, such as that lifting oil pipe, Authorization Notice No. are that the license file of CN105923532B discloses one
Kind oil pipe hanging device, including hanging apparatus and pipe clamping device, the hanging apparatus include lifting hydraulic cylinder, rotating electric machine, hang
Arm, suspension hook, adjusts weight cylinder and clump weight at lifting plate；The pipe clamping device includes tubulature plate, push-tight cylinder, push-tight plate and hanging ring,
Leakage hole is evenly arranged on the tubulature plate.By the way that multiple petroleum pipelines are placed side by side on tubulature plate, push-tight cylinder is stretched
Out so that each petroleum pipeline of push-tight plate push-tight.It can be realized the automatic lifting to oil pipe, lifting efficiency is higher, easy to use.
But above-mentioned documents there is a problem in that：When multiple oil pipes side by side when, propulsion cylinder carry out promote can make
It obtains the opposite sliding of generation between oil pipe and oil pipe and oil pipe outer surface has sump oil attachment.
Summary of the invention
The invention is intended to provide a kind of hanging device for oil pipe, come solve in the prior art multiple oil pipes side by side when,
Propulsion cylinder carries out promoting meeting so that sliding and oil pipe outer surface relatively occur between oil pipe and oil pipe has sump oil attachment
The problem of.
One of this programme is used for the hanging device of oil pipe, the cabinet including hanging apparatus and opened type；The lifting
Device includes arm of crane, and the lower end of the arm of crane is equipped with several suspension hooks, and hoisting rope, the cabinet are equipped on the suspension hook
It is interior to be equipped with bottom plate, clamping part and hanging ring, the wall box be equipped with can fuel feed pump insertion the first opening, the hanging ring fixes
It is mounted on plate upper surface, is evenly spaced apart to be equipped with several sliding slots for running through bottom plate, sliding in the sliding slot in the bottom plate
It is connected with partition, the upper end of the partition is equipped with wedge block, and the diameter of the wedge block is by bottom plate lower end to the side of bottom plate upper end
To being gradually increased；The two sides of the bottom plate slidably connect grip block, are equipped with upper clamp plate between two grip blocks, institute
Upper clamp plate is stated equipped with several grooves corresponding with partition, interior two engagings being equipped with for engaging wedge block of the groove
Block；The clamping part includes hydraulic cylinder, and the hydraulic cylinder is connected with pushing block, and the pushing block is slidably connected in cabinet, institute
It is raised equipped with corresponding with partition first to state pushing block, hinged on the pushing block there are two clamping bar, two clamping bars
It is symmetrical arranged along the central axes of pushing block, the clamping bar is connected with first connecting rod, and first connecting rod is hinged with clamping plate, the folder
Tight plate is oppositely arranged with grip block；The top of the partition is fixed with the second protrusion, sets on the partition around the second protrusion
There is annular opening, slide bar is installed on the partition, the center of the slide bar installs fixed block, is equipped with electricity in the fixed block

Outer surface after having cleaned the sump oil on oil pipe surface, stops motor running for handling some sump oils existing for oil pipe surface.
Then hoisting rope will be passed through on hanging ring, hoisting rope is installed on suspension hook, is started crane, is made the suspension hook of arm of crane lower end
Bottom plate is sling, bottom plate is lifted into required place together with multiple-tubing string.Then oil pipe is unloaded from bottom plate, completion pair
Sump oil cleaning on the outside of the lifting of multiple-tubing string and oil pipe.
Finally bottom plate is resetted using crane, by manually by the engaging block reset on upper clamp plate, resetting partition, being convenient for
Next time to the lifting of oil pipe.
The advantages of this programme, is：1, by Hydraulic Cylinder pushing block, one, which carrys out pushing block, slides the partition made in bottom plate
Sliding will separate between multiple oil pipes, and in each independent region of leisure, two, which carry out pushing block sliding, makes clamping plate push clamping
Plate, grip block generate sliding, and the oil pipe for contacting grip block will not relatively move in the horizontal direction, realize to multiple oil
Manage horizontal and vertical fixation.2, by the way that slide bar, framework, movable frame, rack gear, gear, spray boom etc. are arranged on partition, gear turns
It is dynamic that movable frame is driven to do periodically circulatory motion in framework, so that the spray boom connecting with movable frame is also done periodically annular fortune
Dynamic, the spray head on spray boom carries out the clear of an axial direction to oil pipe during spray boom circulatory motion by the water supply of micro pump
It washes, effect is preferable；Solve the problems, such as that oil pipe outer surface has sump oil attachment in the prior art.
It advanced optimizes, the bottom plate is equipped with several leakage holes.Spray head can pass through the leak on bottom plate when spraying water
Water and sump oil are discharged to the bottom of box by hole together.
It advanced optimizes, the section of the spray head is circle.The section of spray head is circle, can be by the water to gush out burst
Ground gushs out, convenient for eluting the sump oil on oil pipe surface.
It advanced optimizes, is additionally provided with header tank in the cabinet.The extra water that header tank is sprayed convenient for collection spray head
And wash away the sump oil to get off together with water.
It advanced optimizes, the height of first protrusion is consistent with the height of partition.The first protrusion in pushing plate can be used
Partition on bottom plate is pushed, the height for protruding into the first protrusion in bottom plate is exactly equal to the height that partition stretches out bottom plate.
