Abstract
The utility model provides an installation and detachment device of a flow meter. The installation and detachment device of the flow meter comprises two U-shaped shifting fork chucks, a lead screw, a guide rod and a worm and gear transmission mechanism; the middle portions and the lower portions of the two U-shaped shifting fork chucks are arranged on the lead screw and the guide rod respectively; one of the two U-shaped shifting fork chucks is fixedly arranged on the lead screw and the guide rod and the other U-shaped shifting fork chuck is arranged on the lead screw and the guide rod in a sliding mode; the worm and gear transmission mechanism is arranged on the outer side of the sliding U-shaped shifting fork chuck. During usage, a user can rotate a hand wheel or a motor to adjust the distance between the two U-shaped shifting fork chucks to enable a wedge blade to be inserted into a gap formed between flanges arranged at the two ends and continue to rotate the hand wheel or the motor to open pipes arranged at the two ends to detach the flow meter or a valve and the like easily. The installation and detachment device of the flow meter has the advantages of being simple and reasonable in structure, large in opening power, long in holding time, especially suitable for single person operation, free of slip and damage when the flanges are opened and the like. Accordingly, the installation and detachment device of the flow meter is an ideal appliance for detaching and installing devices such as the flange connection especially concave and convex flange connection flow meter or valve.
Description
Technical field
The utility model relates to a kind of being convenient to the utensil of equipment dismounting and change from pipeline such as flange form flowmeter or valve, particularly a kind of can be fast by the utensil of equipment dismounting and change from pipeline such as the flowmeter that adopts concave-convex flange face to connect or valve.
Background technology
The equipment such as the valve using in the valve group of the conveyance conduits such as the oil in field produces, gas, water, flowmeter are more, and the density of arranging is higher, and between pipeline, space is little, and the operating space being removed for repair or replacement is little, and operation easier is large.In order to ensure sealing without leakage, conventionally adopt the concave-convex flange of GB or ring joint face flange to connect being connected between the two ends of valve and instrument and pipeline, make dismounting difficulty larger.When need are changed valve, instrument, after unloading connecting bolt, also to first with crowbar, two flanges that interconnect at valve or instrument two ends be pried open by two people, by a people, use instrument or free-hand slowly mobile valve, instrument again, could be moved out of concave-convex opening or steel loop joint face and will take out, during dismantling, this three people will constantly cooperate, adjust, waste time and energy, toward contact, be not easy valve, instrument to take out smoothly.For the very high valve group of the density of arranging, sometimes also need the valve group of whole conveyance conduit all to pull down, just can reluctantly valve, instrument be taken out.Again because crowbar and other light instruments cannot give flange effective fulcrum, and easily skid, easily flange or pipeline are caused to damage, so this be one very complicated and have an operation of potential safety hazard, current above-mentioned operation be in field operations comparatively generally, work comparatively frequently, very inconvenient in work, waste time and energy, there is higher potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly the defect existing in above-mentioned prior art, a kind of one man operation simple in structure, applicable is provided, uses safety and stability, can helps the quick flowmeter replacer that the equipment such as the flowmeter on pipeline road, valve are carry out demolition and replacement and installed.
Flowmeter replacer of the present utility model, its structure comprises 2 U-shaped shift fork chucks, 1 rhizoid bar, 1 guide post, with 1 Worm and worm-wheel gearing, the middle part of described 2 U-shaped shift fork chucks and bottom are arranged on respectively on screw mandrel and guide post, 1 U-shaped shift fork chuck is wherein fixedly mounted on screw mandrel and guide post, another 1 U-shaped shift fork chuck is slidably mounted on screw mandrel and guide post, Worm and worm-wheel gearing is arranged on the U-shaped shift fork chuck outside of slip, the internal thread rotation that the worm gear axis hole of Worm and worm-wheel gearing is provided with is contained on screw mandrel, one end of the worm screw of Worm and worm-wheel gearing is connected with handwheel.
For the ease of chuck mouth being inserted in the less gap between interconnective two flanges, the U-shaped mouthful inner side of above-mentioned 2 U-shaped shift fork chucks is provided with to the wedge shape sword extending in bayonet socket.
In order further to increase work efficiency, can set up motor and drive, the output shaft of described motor is connected with the other end of the worm screw of Worm and worm-wheel gearing.
During operation, first the connecting bolt of equipment two end flanges such as the flowmeter of needs dismounting or valve is unloaded, by rotating handwheel or motor, drive, distance between 2 U-shaped shift fork chucks is adjusted to wedge shape sword can be inserted in two end flanges gaps, be rotated further again handwheel or motor, drive worm screw that worm gear is rotated, because the internal thread rotation on worm-wheel shaft is contained on screw mandrel, again because screw mandrel and guide post maintain static, make Worm and worm-wheel gearing the circular-rotation of worm screw can be become to the linear reciprocal movement carrying out along screw mandrel and guide post, the pipe flange at two ends can be strutted and by flowmeter, the equipment such as valve easily unload, strutting apart from can remain to always of this device loaded onto the equipment such as new flowmeter or valve again.Have simple and reasonable, strut strength large, retention time is long, be particularly suitable for one man operation, when flange struts, non-slip not damaged, safe and reliable, efficiency advantages of higher, can to equipment such as the flowmeter on pipeline or valves, carry out demolition and replacement easily, be a kind of desirable utensil that the equipment such as flowmeter that concave-convex flange formula particularly connects or valve carry out dismounting that flange form is connected.The departments such as oil, chemical industry that are particularly suitable for are used.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of use status architecture schematic diagram of the present utility model.
The specific embodiment
Referring to accompanying drawing, 1 in figure is the U-shaped shift fork chuck in left side, and 1-1 is the wedge shape sword of the U-shaped shift fork chuck in left side, the 2nd, and the U-shaped shift fork chuck on right side, 2-1 is the wedge shape sword of the U-shaped shift fork chuck on right side, the 3rd, and screw mandrel, the 4th, guide post, the 5th, Worm and worm-wheel gearing, the 6th, handwheel, the 7th, locating snap ring.
Flowmeter replacer of the present utility model, its structure as shown in Figure 1, comprise 2 U-shaped shift fork chucks 1 and 2, 1 rhizoid bar 3, 1 guide post 4, with 1 Worm and worm-wheel gearing 5, described 2 U-shaped shift fork chucks 1 and 2 middle part and bottom are arranged on respectively on screw mandrel 3 and guide post 4, 1 U-shaped shift fork chuck 1 is wherein fixedly mounted on screw mandrel 3 and guide post 4, another 1 U-shaped shift fork chuck 2 is slidably mounted on screw mandrel 3 and guide post 4, Worm and worm-wheel gearing 5 is arranged on U-shaped shift fork chuck 2 outsides of slip, the internal thread rotation that the worm gear axis hole of Worm and worm-wheel gearing 5 is provided with is contained on screw mandrel 3, one end of the worm screw of Worm and worm-wheel gearing 5 is connected with handwheel 6.
