Abstract
Bell-mouthed top is conveniently replaceable the utility model discloses one kind and drives back-up tong device, belongs to oil drilling and r eoovery machine technical field, including two monomer back-up tong hydraulic cylinder assemblies, horn mouth and back-up tong intermediate plate；Two monomer back-up tong hydraulic cylinder assemblies are connect by connecting pin with back-up tong intermediate plate；It is characterized by: being provided with a U-shaped slideway on each monomer back-up tong hydraulic cylinder assembly, the U-shaped slideway is fixedly connected by bolt and elastic washer with monomer back-up tong hydraulic cylinder assembly；The horn mouth is fixedly connected by bolt and elastic washer with two U-shaped slideways.By using above-mentioned technical proposal, since horn mouth is located at the top of U-shaped slideway, when needing replacing horn mouth, the bolt and elastic washer between horn mouth and U-shaped slideway need to be only unloaded, so that it may easily move horizontally out horn mouth.This patent structure is simple, does not need more people operation simultaneously, and also needing not worry about horn mouth has the problems such as falling with the disassembly of bolt difficulty.Device operation is convenient, safe and reliable.
Description
Technical field
The utility model belongs to oil drilling and r eoovery machine technical field more particularly to one kind is conveniently replaceable bell-mouthed top and drives back
Clamp device.
Background technique
Currently, the essential product for having become oil drilling is driven on top.Relative to traditional brill disk kelly bar operation mode, top
It drives and is crept into using drill rod stand column, the operation such as circulating fluid, upper shackle, back reaming may be implemented, improve drilling efficiency and work
Industry safety.Drilling time 20%-25% can be saved by being driven using top, and can prevent the generation of lock of tool drilling.For horizontal well, tiltedly
Well, highly difficult directional well are obviously improved effect.
Bell-mouthed effect is play the guiding role when drilling rod drives connection with top.According to different wells in drilling operation course
Deep drilling well requirement, the drilling rod for needing to be separately connected different size diameter is driven on top.The drilling rod of different size diameter needs correspondence to match
The horn mouth of standby different size.Simultaneously as drilling rod often impinges upon on horn mouth, bell-mouthed damage is caused, so often
Every needing to change new horn mouth for a period of time to guarantee not influence the normal work that top is driven.
Current structure is that horn mouth is fixed on monomer back-up tong hydraulic cylinder assembly with bolt and elastic washer, due to loudspeaker
Mouth is located at below monomer back-up tong hydraulic cylinder assembly, therefore must have an operating personnel with the hands to lift loudspeaker when replacement horn mouth
Mouth, another operating personnel all disassemble bolt and elastic washer with spanner, and horn mouth could be the same as monomer back-up tong liquid
Cylinder pressure assembly separates.Due to about 30 kilograms of bell-mouthed monomer weight, disassembly or set-up time are longer, and operating personnel lifts
Horn mouth is very painstaking, exist simultaneously weight accidentally drop fall, bolt be in when stress it is bad disassembly or installation etc. hidden danger.
Utility model content
In view of the drawbacks of the prior art, the utility model provides one kind and is conveniently replaceable bell-mouthed top drive back-up tong device, should
Patent is indirectly connected with by the realization of U-shaped slideway to bell-mouthed, on the one hand improves the bell-mouthed convenience of replacement, in addition a side
Face improves safety.
Used by the utility model the specific technical proposal is:
One kind being conveniently replaceable bell-mouthed top and drives back-up tong device, including two monomer back-up tong hydraulic cylinder assemblies (1), horn mouths
(6) and back-up tong intermediate plate (2)；Two monomer back-up tong hydraulic cylinder assemblies (1) are connect by connecting pin (5) with back-up tong intermediate plate (2)；
It is characterized by: being provided with a U-shaped slideway (7) on each monomer back-up tong hydraulic cylinder assembly (1), the U-shaped slideway (7) is logical
It crosses bolt (3) and elastic washer (4) is fixedly connected with monomer back-up tong hydraulic cylinder assembly (1)；The horn mouth (6) passes through bolt
(3) it is fixedly connected with elastic washer (4) with two U-shaped slideways (7).
Further, the U-shaped slideway (7) and bell-mouthed mating surface are equipped with positive stop lug boss (8).
The advantages of the utility model and good effect are as follows:
By using above-mentioned technical proposal, this patent uses U-shaped cunning between monomer back-up tong hydraulic cylinder assembly and horn mouth
Road is horizontally moved formula connection.Monomer back-up tong hydraulic cylinder assembly and U-shaped slideway are fixedly connected with bolt and elastic washer.
Horn mouth is fixedly connected with U-shaped slideway with bolt and elastic washer.Since horn mouth is located at the top of U-shaped slideway, need
When replacing horn mouth, the bolt and elastic washer between horn mouth and U-shaped slideway need to be only unloaded, so that it may easily move horizontally
Horn mouth out.This patent structure is simple, does not need more people operation simultaneously, also needs not worry about horn mouth and have to fall and tear open with bolt difficulty
The problems such as unloading.Device operation is convenient, safe and reliable.

Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing.
The structure of the utility model is explained in detail with reference to the accompanying drawing.
Please refer to Fig. 1 and Fig. 2: one kind being conveniently replaceable bell-mouthed top and drives back-up tong device, including two monomer back-up tongs are hydraulic
Cylinder assembly 1, horn mouth 6 and back-up tong intermediate plate 2；Two monomer back-up tong hydraulic cylinder assemblies 1 pass through connecting pin 5 and back-up tong intermediate plate 2
Connection；A U-shaped slideway 7 is provided on each monomer back-up tong hydraulic cylinder assembly 1, the U-shaped slideway 7 passes through bolt 3 and bullet
Property washer 4 is fixedly connected with monomer back-up tong hydraulic cylinder assembly 1；The horn mouth 6 is U-shaped by bolt 3 and elastic washer 4 and two
Slideway 7 is fixedly connected.By the bolt 3 and elastic washer 4 between disassembly horn mouth 6 and U-shaped slideway 7, horn mouth can be realized
