Description
Technical field
The invention belongs to reaction nut technical fields, and in particular to a kind of reaction nut of fast demountable.
Background technique
Currently, the reaction nut of domestic bolt stretching machine is generally common nut, plain nut and screw rod pass through spiral shell
Line cooperation moves in a straight line after nut rotation.However plain nut is when cooperating the long stretching screw of plate-type heat-exchange exchanger, it is real
The stroke on border is helix, needs to rotate very long distance, nut size is big, and installation process is time-consuming and laborious.
In the technical specification of nuclear power plant, it is desirable that the recovery pot life of heat-exchangers of the plate type is 72h, using common anti-
Effect nut can occupy the more construction time, therefore need to optimize and solve the problems, such as this.
Summary of the invention
The purpose of the present invention is to provide a kind of reaction nuts of fast demountable, use this nut as bolt tension
The reaction nut of machine can realize the requirement of fast assembling-disassembling in the case where intensity is met the requirements.
Technical scheme is as follows:
A kind of reaction nut of fast demountable, including it is left semi-ring, right semi-ring, link block, semicircle part, straight hand lever, heavy
Hook bolt, bolt and nut component；
Groove is circumferentially processed along semi-ring respectively in one end Middle face of the left semi-ring and one end Middle face of right semi-ring, when
When left semi-ring and right semi-ring surround annulus shape, the groove on left semi-ring is opposite with the groove location on right semi-ring, forms connection
The mounting groove of block；The link block is set in above-mentioned mounting groove, and is connected respectively by bolt with left semi-ring and right semi-ring；
Two slots are opened up in the other end trisection posistion of the left semi-ring, two semicircle parts are respectively arranged in two slots, and
It is connected by dormant bolt with left semi-ring；
It slots in the other end center of the right semi-ring, straight hand lever is set in above-mentioned slot, and passes through dormant bolt
It is connected with right semi-ring；
The straight hand lever is located between two semicircle parts, and is fixedly clamped by bolt and nut component.
It is equipped with and the matched screw thread of long bolt in the inner wall of the left semi-ring and right semi-ring.
The middle position of the left semi-ring and right semi-ring outer wall is scabbled respectively in axial direction, for matching suitable open spanner
Hand.
The link block passes through the dormant bolt that the annulus that two edges surround axially is arranged and left semi-ring and right half respectively
Ring is connected.
Bolt stretching machine suitable for heat-exchangers of the plate type.
After installing bolt stretching machine, straight hand lever is located at left half ring position, is in open position, at this time left semi-ring and right semi-ring
Internal diameter is greater than the external screw thread major diameter of long bolt, and reaction nut can pack into long bolt, compared to the helix of plain nut, save significantly
Moving distance and time are saved.
In the proper site that need to be locked, straight hand lever is located at right half ring position, at this time the inner thread of left semi-ring and right semi-ring
Locking is engaged with the external screw thread of long bolt.
When the inner thread of left semi-ring and right semi-ring is in the external screw thread of long bolt engages locking state, rotation can be passed through
Turn nut trim locations.
Remarkable result of the invention is:
(1) reaction nut of the present invention as bolt stretching machine can bear to stretch in the case where intensity is met the requirements
The normal pressure of machine realizes the requirement being rapidly assembled and disassembled, and saves the working time, has weight in the construction site that having time requires
Want meaning.
(2) reaction nut of the present invention can be applied to the long bolt of different size, the practicality and can by modification size
There is very broad application prospect and application value by property, be worthy to be popularized.

Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
A kind of reaction nut of fast demountable as shown in Figures 1 to 3, the bolt for being mainly used for heat-exchangers of the plate type are drawn
Stretch machine, including left semi-ring 1, right semi-ring 2, link block 3, semicircle part 4, straight hand lever 5, dormant bolt 6, bolt and nut component 7.
It is equipped in the inner wall of the left semi-ring 1 and right semi-ring 2 and distinguishes with the matched screw thread of long bolt, the middle position of outer wall
It is scabbled along axial direction, for matching suitable open-end wrench.
Groove is circumferentially processed respectively in one end Middle face of the left semi-ring 1 and one end Middle face of right semi-ring 2, works as a left side
When semi-ring 1 and right semi-ring 2 surround annulus shape, the groove on Zuo Banhuan 1 is opposite with the groove location on right semi-ring 2, the company of being formed
Connect the mounting groove of block 3.The link block 3 is set in above-mentioned mounting groove, and the annulus surrounded respectively by two edges is axially set
The dormant bolt 6 set is connected with left semi-ring 1 and right semi-ring 2.
Two slots are opened up in the other end trisection posistion of the left semi-ring 1, two semicircle parts 4 are respectively arranged in two slots,
And it is connected by dormant bolt 6 with left semi-ring 1.
It slots in the other end center of the right semi-ring 2, straight hand lever 5 is set in above-mentioned slot, and passes through countersunk head spiral shell
Bolt 6 is connected with right semi-ring 2.
The straight hand lever 5 is located between two semicircle parts 4, and is fixedly clamped by bolt and nut component 7.
After bolt stretching machine is installed, straight hand lever 5 is pulled to left 1 position of semi-ring, is in open position, at this time left semi-ring 1 and the right side
The internal diameter of semi-ring 2 is greater than the external screw thread major diameter of long bolt, and reaction nut can pack into long bolt, compared to the spiral of plain nut
Moving distance and time is greatly saved in line；In the proper site that need to be locked, straight hand lever 5 is pulled to right 2 position of semi-ring, at this time
Left semi-ring 1 and the inner thread of right semi-ring 2 and the external screw thread of long bolt engage locking, can pass through rotating nuts trim locations；It tears open
Except the process of reaction nut is executed according to reverse procedure.
