Description
Technical field
The present invention relates to concrete product manufacturing technology fields, and in particular to a kind of jack check tooling.
Background technology
With the continuous development of modernization power grid construction and the communication technology, high intensity, big moment of flexure, the annular of length speciality are mixed
Solidifying soil electric pole continues on, and highest is to 45m, and reinforced concrete pole can not be kept away in production, transport, operation for many years
There is circumferential crack with exempting from.Although in National Standard of the People's Republic of China GB/T 4623-2006《Annular concrete electric pole》
There is regulation in table 6：Reinforced concrete pole must not have longitudinal crack, circumferential fracture width to be not greater than 0.05mm, again
6.5.1 item provides：When reinforced concrete pole loading to cracking examines moment of flexure, fracture width should be less than 0.2mm.This be by
In this structure of reinforced concrete pole necessarily lead to as a result, because the compression strength of concrete component is very high, but tension
Intensity is very low, only the 1/18 of compression strength.Larger drawing is easily generated in the tensile region of component during production and transport
Stress, since the tensile strength of concrete is very low, so as to cause concrete members face checking, especially as 190 × 15m this
The elongated reinforced concrete pole of kind, is more prone to generate circumferential crack.
Prestressed stretch-draw uses intelligent tensioning, the elongation of intelligent tensioning to pass through thousand in stretching process by jack substantially
The sensor and related accessory installed on jin top are passed to after detecting on computer, but jack is easy after multiple movement or use
Faulty sensor or misalignment are caused, the elongation value of stretching that computer is shown is abnormal, affects the program of tensioning to a certain extent,
And common being measured with Steel Ruler is not only susceptible to error in reading, also there is security risk to a certain extent.It is very heavy
Top plays a crucial role the quality of product, jack it is accurate whether decide the quality of product quality, for this
Kind situation, check tooling originally comprehensive cannot make comprehensive check to jack, need a kind of novel check
Tooling carries out jack in due course detection, both can guarantee the quality of product, can also improve production efficiency and to a certain degree
On be effectively guaranteed the personal safety of operating personnel.And reinforcing bar, after anchoring, misoperation easy tos produce in stretching process
Situations such as stripped thread, fracture, reduce the quality of tensioning.
It is a kind of pre- to the application of big moment of flexure prestressed concrete electric pole that application No. is 201110053856.1 disclosure of the invention
The tensioning equipment and method of stress, by jack pulling shaft and the tensioning nut screwed connection of tensioning pawl, the pawl hooks of tensioning pawl are put in
Inner arc muscle is hooked in steel plate ring, and tensioning is carried out to the reinforcing bar being anchored on steel plate ring, uses and is twisted with the adjusting screw rod for fixing disk
The outer fixation for pressing closer punching block end keeps the tension stress of deformed bar.The technical effects of the invention are that using opening
Pulling claw hooks inner arc muscle in steel plate ring and carries out tensioning, and because tensioning pawl is small away from the deformed bar arm of force, therefore the moment of flexure generated is small,
Under large-tonnage stretching force, steel plate ring is indeformable, using tensioning nut come the pulling shaft of screwed connection tensioning pawl and jack, avoids original
When having bolt fixation, the technical issues of bolt cannot bear large-tonnage shearing force.Outer fixed, work is carried out using the screw rod of fixed disk
Sequence is simple and convenient.The spike of support uses movable supporting feet, conveniently adapts to the large bending moment electrical pole for producing various different sizes.The invention
Jack is not checked, can not recognize whether the process of tensioning is smooth.
Application No. is 201520831146.0 utility models to disclose a kind of sensor of intelligent tensioning measurement elongation
Tooling, including jack and sensor are checked, the sensor surface is equipped with sensor loop bar, and the sensor loop bar, which is equipped with, to be carved
Degree, 0 value of the scale is the complete oil return of jack and ejector piston is in the position that bottom elongation is 0, the sensing
Device position corresponding with jack plane is provided with measurement pointer.The utility model can be in sensor because of the feelings of a variety of causes failure
Ensure normal tensioning under condition；The measurement of stretching extension value is accurate, reduces the security risk of elongation measurement.The utility model is only right
The length of tensioning is checked, single effect.
