Abstract
The utility model discloses a portable bolt dismouting hydraulic wrench, including the pneumatic cylinder that contains the hydraulic stem, the lower end connection of pneumatic cylinder strikes the spanner, the last end connection of pneumatic cylinder has the connecting rod, the lower tip of connecting rod with the middle part of strikeing the spanner is connected, the upper and lower both ends of pneumatic cylinder are provided with quick -operation joint respectively. The utility model discloses can effectively improve the maintenance efficiency of well control equipment such as preventer, production tree, reduce personnel intensity of labour, reduce the safe risk coefficient in the maintenance process to reduce maintenance manufacturing cost.
Description
Technical field
This utility model is related to spanner, and more particularly to a kind of Portable screw bolt dismounts hydraulic spanner.
Background technology
Bolt is the most frequently used, reliable fastening means in plant equipment, can use with nut screw connection, also can be used alone.
Preventer and production tree are petroleum gas one of requisite equipment in recovery process, have many bolt connections thereon.
Used as the main preventer in Bohai Sea Area, production tree repair and maintenance service provider, the equipment for having nearly 200 sets every year is keeped in repair,
In maintenance process, assembling-disassembling bolt work occupies most of maintenance time, causes maintenance efficiency low.
To reduce labor intensity, strengthen safety, each producer have developed the bolt disassembly work of different size, structure on the market
Tool, is commonly called as hydraulic spanner.These hydraulic spanners using hydraulic pressure as power source, drive nut rotation by the sleeve of different size,
So as to reach the purpose of assembling-disassembling bolt.Though such hydraulic spanner automaticity is higher, to the bolt disassembly on some equipment
The suitability is poor, such as the equipment such as the preventer of drilling and repairing machine homework department maintenance, production tree.Most of spiral shell on preventer, production tree
The rotary space of bolt is less, and hydraulic spanner uses limited space, cannot normal mounting on corresponding nut, it is impossible to complete spiral shell
The dismounting work of bolt.
As hydraulic spanner cannot be normally used in preventer or production tree maintenance process, in land workshop or marine flat
When platform carries out repair and maintenance work, it has to take the bolt on the mode handling facilities of artificial percussion, so not only labor intensity is high,
Repair and maintenance efficiency is low, and work progress security risk coefficient is greatly increased.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of Portable screw bolt dismounting hydraulic pressure is pulled
Handss, by the use of this hydraulic spanner, can effectively improve the maintenance efficiency of the well-control equipments such as preventer, production tree, reduce people
Member's labor intensity, reduces the security risk coefficient in maintenance process, and reduces keeping in repair production cost.
The technical scheme adopted by this utility model is：A kind of Portable screw bolt dismounts hydraulic spanner, including containing hydraulic pressure
The hydraulic cylinder of bar, the bottom of the hydraulic cylinder are connected with percussion spanner, and the upper end of the hydraulic cylinder is connected with connecting rod, described
The bottom of connecting rod is connected with the middle part of the percussion spanner；The upper/lower terminal of the hydraulic cylinder is respectively arranged with and quickly connects
Head.
The root for tapping spanner is connected with the bottom of the hydraulic stem by pin.
The connecting rod is L-type structure, and its galianconism is connected with the upper end of the hydraulic stem by pin, and which is long-armed to pass through
Pin is connected with the middle part of the percussion spanner.
The beneficial effects of the utility model are：
1st, this utility model hydraulic spanner is designed based on " linkage " and " lever principle " in theory of mechanics, even
The closed interval composition linkage formed by bar, hydraulic cylinder and percussion spanner, taps spanner with its junction point shape with connecting rod
Into lever.When hydraulic stem is stretched out under hydraulic action, linkage deforms, and drives percussion spanner to make to strike around vertex rotations
The Flos Mume end for hitting spanner rotates, so as to reach the purpose of rotation nut.
2nd, the hydraulic spanner for providing on the market at present is more with electric hydraulic pump as pressure dynamics source, need to be with electricity drive during use
Hydraulic pump works, and the hydraulic pump of this type exists in preventer, production tree etc. and is suitable on the less equipment in bolt convolution space
Property is poor.This utility model hydraulic spanner can also can be used for operation on the sea in workshop using handlance as power source, and for returning
The less bolt in rotation space has the very strong suitability, has been compared with the prior art following advantage：(1) it is simple to operate, it is safe；
(2) can be used for the limited place of various nut revolution spaces；(3) for the nut of different size, it is only necessary to change corresponding Flos Mume
Spanner, can meet the dismounting work of most of bolt；(4) this utility model hydraulic spanner power can be carried with armrest press pump
For without using power such as power supplys；(5) it is cheap.
Description of the drawings
Fig. 1：This utility model structural representation；
Fig. 2：This utility model scheme of installation during one tight bolt of embodiment；
Fig. 3：This utility model scheme of installation during one loose bolt of embodiment.
Accompanying drawing is marked：1st, tap spanner；2nd, pin；3rd, hydraulic cylinder；4th, snap joint；5th, connecting rod.
Specific embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of Portable screw bolt dismounts hydraulic spanner, including the hydraulic cylinder 3 containing hydraulic stem, the liquid
The bottom of cylinder pressure 3 is connected with percussion spanner 1, the Flos Mume end for tapping spanner 1 outwards, its root by pin 2 with it is described
The bottom of hydraulic stem is connected.The upper end of the hydraulic cylinder 3 is connected with connecting rod 5, and the connecting rod 5 is L-type structure, its galianconism
It is connected with the upper end of the hydraulic stem by pin 2, its long-armed bottom is by pin 2 and the percussion spanner 1
Middle part is connected.The upper/lower terminal of the hydraulic cylinder 3 is respectively arranged with snap joint 4.
This utility model Portable screw bolt dismounts hydraulic spanner and taps spanner 1 and hydraulic cylinder 3 (containing hydraulic pressure by connecting rod 5, customization
Bar) constitute, the connection of each parts part is pin link.Hydraulic spanner design with theory of mechanics in " linkage " and
Based on " lever principle ", the closed interval composition linkage formed by the connecting rod 5, hydraulic cylinder 3 and percussion spanner 1 in Fig. 1,
Tap spanner 1 and lever is formed with its junction point with connecting rod 5.When hydraulic stem is stretched out under hydraulic action, linkage occurs
Deformation, drives percussion spanner 1 to rotate the Flos Mume end of percussion spanner 1 around vertex rotations, so as to reach the purpose of rotation nut.
When in use, snap joint 4 is connected this utility model hydraulic spanner with electric hydraulic pump or hydraulic hand-pump, is tapped
1 Flos Mume end of spanner is enclosed within corresponding nut, and connecting rod 5 leans against other positions of adjacent nut or equipment, is that the rotation of nut is carried
For counteractive support power.
Embodiment one
As a example by dismounting end face of flange bolt.During tight bolt, the installation of hydraulic spanner is as shown in Fig. 2 when hydraulic stem stretches out
When drive tap spanner 1 rotate and drive bolt to rotate, reach the purpose of tight bolt；During loose bolt, as shown in Figure 3, it is only necessary to will
Hydraulic spanner upset is installed on corresponding nut.
