Description
Technical field
The present invention relates to a kind of prestressed concrete electric pole stretching and anchoring device, belong to power transmission technical field.
Background technology
Along with the fast development of China's power industry, bearing capacity and life requirement to concurrent are more and more higher, special
Being not prestressed concrete electric pole, its price is low and service life is long, and market demand amount is big.But bearing capacity is the biggest
Prestressed concrete electric pole, its stretching force born is the biggest, this just processing to prestressed concrete electric pole propose more
High requirement.In the process of manufacture of prestressed concrete electric pole, stretch-draw is critical process, and it directly influences electric pole
Product quality.
Conventional stretching and anchoring device generally comprises stretch-draw traction piece, tensioning head, fastening support etc..Patent No.
The Chinese patent of 201320142479.3 discloses a kind of stretch-draw for big moment of flexure big tip footpath prestressed reinforced concrete electric pole and fills
Put, its stretch-draw traction piece be stretch-draw pawl, tensioning head be steel plate ring, fastening support is fixed disk, also includes support.Very heavy
The pulling shaft on top is by tensioning nut and stretch-draw pawl screwed connection, and stretch-draw pawl is connected with steel plate ring, and Bar Anchorage is on steel plate ring.
Described fixed disk is sheathed on steel plate ring outer wall, and fixed disk is provided with the screw rod for withstanding punching block, and the pulling shaft of jack is through support
The through hole of frame, support withstands the flanged plate of punching block by the spike arranged on support, and its spike is dismountable movable supporting feet,
And in the spike set being arranged on support.This tensioning equipment is connected transmission stretching force by stretch-draw pawl with steel plate ring, due to stretch-draw
Pawl is connected with steel plate ring by longer hook pawl, under bigger stretching force effect, hooks pawl and is easily deformed and causes institute on steel plate ring
The stretching force being subject to is uneven, is also easy to cause stretch-draw pawl and steel plate ring deformation.This tensioning equipment is come by the screw rod on fixed disk
Withstanding punching block, the lifting surface area between screw rod and punching block is the least, screw rod due to by bigger pressure and be susceptible to deformation,
Causing steel plate ring to loosen, deformed bar stretch-draw effect dies down and even disappears, and the fastening of screw rod needs each screw rod independent
Operation, operation is loaded down with trivial details.
Summary of the invention
It is an object of the invention to provide a kind of tension rod and tensioning head is easy to connect and stretching force transmits uniform prestressing force and mixes
Solidifying soil electric pole stretching and anchoring device.
In order to realize object above, technical scheme is as follows:
A kind of prestressed concrete electric pole stretching and anchoring device, including the tensioning head for the reinforcing bar that is connected, for jack even
Connect and draw tensioning head stretch-draw traction piece, by Screw assembly on tensioning head for block on punching block to keep stretch-draw
The screw threads for fastening support member of the tensioning state of head, described stretch-draw traction piece is shaft-like tension rod, and described tensioning head is internal to be arranged
Having the through hole that the head for tension rod enters, on described through-hole wall, circumferentially uniform intervals is provided with plural to described
Through hole center extend link plate, tension rod head circumferentially uniform intervals be provided with plural for described link plate block
The stretch-draw pawl coordinated, leaves between described spaced link plate and is available for the link plate gap that stretch-draw pawl passes through, and described interval sets
The stretch-draw pawl gap passed through for link plate is left between the stretch-draw pawl put.
The face that described link plate contacts with corresponding stretch-draw pawl is the inclined-plane cooperated or is perpendicular to the vertical of tension rod axial line
Face.
Described tensioning head sets described through hole cylinder and the annular being located at cylinder peripheral in including turn edge, and described annular turns edge upper edge
It is provided at circumferentially spaced the reinforced hole for connecting reinforcing bar.
Described screw threads for fastening support member is anchor disc, and anchor disc includes trying to get to the heart of a matter and be convexly equipped in the boss of front end of trying to get to the heart of a matter, and boss has
For the front end face coordinated with punching block block, described in try to get to the heart of a matter and be provided centrally with and the screwed hole of described tensioning head threaded engagement, institute
The afterbody stating tensioning head cylinder is provided with external screw thread, and the screwed hole threaded engagement at center of trying to get to the heart of a matter with anchor disc is connected, described anchor disc
Boss periphery on be provided with rotating handle.
Described boss be fixedly connected on described in try to get to the heart of a matter on annular boss, or upper edge of trying to get to the heart of a matter described in being fixedly connected on tries to get to the heart of a matter week
To equally distributed projection.
The present invention uses interior stretch-draw, is respectively provided with stretch-draw pawl and link plate on tension rod and tensioning head, by the phase of both rotations
Position is realized tension rod and the fastening of tensioning head and disengagement, it is achieved that tension rod is connected with the quick and convenient of tensioning head.Pass through
Arrange shaft-like tension rod to be connected with jack piston rod, it is possible to the stretching force making jack is the most steady by the body of rod of tension rod
Surely being transferred on tensioning head, will not produce the deflection of stretching force, stretch-draw pawl is the fixed lobe on tension rod, in bigger stretch-draw
Under the effect of power, tension rod and stretch-draw pawl are all not likely to produce deformation, are effectively guaranteed uniform, the stable delivery of stretching force.
Further, the anchor disc that the present invention is sleeved on tensioning head by setting, after stretching force is stable, can be by rotation
Turn anchor disc to make it push up to be pressed on punching block, anchor disc can be realized the Quick fastening top of punching block is pressed, and anchor disc is by its week
The Pan Bi enclosed presses with punching block top, uses extenal fixation mode, and lifting surface area is big, makes stretching force act on uniformly and stably on punching block.
It addition, anchor disc Pan Bi defines a space, tensioning head is positioned at this interior volume, and tension rod passes inside tensioning head, three
Individual component is from inside to outside socketed, and compact conformation saves space.
