Abstract
The utility model relates to an integral releasing and tensioning device for a concrete pipe pile, which comprises a support. The integral releasing and tensioning device is characterized in that a rotatable releasing and tensioning sleeve is mounted on the support, an outer ring of the releasing and tensioning sleeve is a ratchet wheel structure, a driving ring driven by a cylinder is sleeved on the outside of the ratchet wheel structure, a hole is disposed on an inner ring of the driving ring, a ratchet is embedded in the hole, and a compression spring which drives the ratchet to be abutted to a ratchet wheel is embedded on the back of the ratchet. The size and the shape of the releasing and tensioning sleeve match with those of a locking nut of a pipe pile tensioning system, so that the releasing and tensioning sleeve can be exactly sleeved on the locking nut, the driving ring is driven by the cylinder to rotate by a certain angle, the ratchet is abutted to the ratchet wheel structure to drive the ratchet wheel structure to rotate so that the locking nut is released, directional locking can be prevented by the ratchet wheel and the ratchet jointly, the locking nut can be disassembled conveniently by workers, the integral releasing and tensioning device is simple in structure and high in releasing and tensioning efficiency, labor intensity of the workers is greatly reduced, and the problem that some upset heads fall off due to uneven releasing and tensioning stress can be avoided.
Description
Technical field
The utility model relates to a kind of concrete tubular pile and puts a device, and particularly a kind of concrete tubular pile integral body simple in structure, easy to use is put a device.
Background technology
Along with the development of concrete technology, the technology of concrete tubular pile also reaches its maturity, and except that being applied to industry, civil buildings, also is widely used in each field such as bridge, harbour, railway or hydraulic engineering.
When carrying out the production of concrete tubular pile, need through feeding, stretch-draw, centrifugal, normal temperature is steam-cured, put open, operations such as the demoulding and high-pressure steaming and cultivating.When putting; Need the artificial tailgate nut or the locking nut that unclamp tensioning system, tailgate nut quantity is more, and the inhomogeneous part heading obscission that causes of prestressing force possibly occur when putting; And because the locking nut coupling mechanism force of tubular piles stretching system is bigger; Waste time and energy, labor strength is big, and has reduced production efficiency.
Summary of the invention
The technical problem that the utility model will solve provides a kind of tension prestress concrete tubular pile integral body even, simple in structure, easy to use of putting and puts a device.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of concrete tubular pile integral body is put a device, comprises a support; Its innovative point is: a rotating sleeve of putting is installed on the said support; A said sleeve outer ring of putting is a ratchet structure, and said ratchet structure is set with the driving ring by air cylinder driven outward, and the inner ring of said driving ring has the hole; Said hole is embedded with ratchet, and the said ratchet back side is embedded with the compression spring that ratchet is propped up ratchet.
The advantage of the utility model is: according to the locking nut size and the supporting sleeve of putting accordingly of profile of tubular piles stretching system, make that putting a sleeve just can be sleeved on the locking nut, turns an angle through the air cylinder driven driving ring; Prop up its rotation of ratchet structure driving through ratchet and unclamp locking nut; The combination of ratchet and ratchet can prevent direction locking, makes things convenient for the workman that locking nut is dismantled, and is simple in structure; Put an efficient height, greatly reduce working strength of workers; When putting directly the dismounting locking nut carry out integral body and put and open, can avoid owing to put the inhomogeneous part heading that causes of the tension prestress problem that comes off.
Description of drawings
Fig. 1 is put an apparatus structure sketch map for the utility model concrete tubular pile integral body.
The specific embodiment
As shown in Figure 1, comprise support 1, put a sleeve 2, driving ring 3, ratchet 4, compression spring 5, cylinder 6.
The one rotating sleeve 2 of putting is installed, the locking nut that this inwall of putting a sleeve 2 just can chimeric tensioning system on the above-mentioned support 1.The front end outer ring of putting a sleeve 2 is provided with ratchet structure; Put outside the sleeve 2 and be set with rotating driving ring 3, have a sector hole on the inner ring of this driving ring 3, the hole is embedded with ratchet 4; Be embedded with compression spring 5 in the hole, the back side of ratchet 4, this compression spring 5 promotes ratchet 4 and props up ratchet structure.
Driving ring 3 is connected with cylinder 6 through otic placode, and the piston rod end of cylinder 6 is connected with otic placode, support 1 through bearing pin respectively with cylinder ends.
During use, but with on the locking nut of putting a sleeve 2 suit tensioning systems, turn an angle through air cylinder driven driving ring 3, ratchet 4 props up its rotation of ratchet structure driving and unclamps locking nut, makes things convenient for the workman that locking nut is dismantled.
