Description
Technical field
The utility model relates to the positioner in the penstock straight tube stiffening ring assembling that stiffening ring string slurry hole is arranged that is applicable to any thickness of slab, particularly a kind of stiffening ring assembly unit positioner.
Background technology
At present, hydropower station pressure steel pipe stiffening ring spelling adopts the interim frock of spot welding triangle drift conduct on steel pipe tube wall tube coupling usually, treats after stiffening ring installs the triangle drift to be cut off, then with angle grinding machine polishing tube coupling crator.This construction method has harmful effect to penstock tube coupling performance, and the crator of polishing has simultaneously also increased artificial and auxilliary material use quantity, has reduced the penstock make efficiency.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of stiffening ring assembly unit positioner, can avoid on tube coupling spot welding to the adverse effect of tube coupling performance, can also effectively reduce the consumption of artificial and auxilliary material simultaneously, effectively improves the make efficiency of penstock.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of stiffening ring assembly unit positioner, and a plurality of backstays connect by the spacing connection strap, and the backstay upper end is provided with hook, hook is provided with the adjusting bolt, and backstay is provided with at least one supporting member.
Described supporting member triangularity, at least one pin joint on it adopts latch to connect.
Described supporting member is provided with the flat connecting plate of inserting.
Also be provided with shackle on the described backstay.
A kind of stiffening ring assembly unit positioner that the utility model provides, by the slurry of the stiffening ring string in design hole site backstay is installed, the backstay upper end is provided with hook, the position of assembly unit stiffening ring is provided with triangle, folding supporting member, can realize location and the installation of stiffening ring on tube coupling easily, avoid on tube coupling the interim frock of spot welding to the adverse effect of steel pipe mother metal performance, backstay can adopt the obsolete material processing of making the steel pipe tube coupling, and can reuse, effectively reduce the consumption of artificial and auxilliary material, effectively improve the make efficiency of penstock.Backstay can be disassembled into a plurality of lighter members by the shackle on the backstay, be convenient to installation and removal.
The utility model assembling structure is dexterous convenient, and weight is slim and graceful, and cost of manufacture is low, can reuse.After coming into operation, it is about 40% to improve work efficiency than former stiffening ring spelling method, and it is about 60% that artificial and auxilliary material consumption reduces, and effectively controlled construction cost, and the spelling of penstock stiffening ring of the same type all can adopt.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and example: Fig. 1 is an installation schematic top plan view of the present utility model; Fig. 2 is the structural representation of backstay in the utility model; Fig. 3 is a partial enlarged drawing among Fig. 1.
The specific embodiment
In Fig. 1, Fig. 2 and Fig. 3, a kind of stiffening ring assembly unit positioner, a plurality of backstays 2 connect by spacing connection strap 5, and backstay 2 upper ends are provided with hook 21, and hook 21 is provided with regulates bolt 22, and backstay 2 is provided with at least one supporting member 23.Quantity according to steel pipe length, pipe diameter, stiffening ring 3 changes, and according to the quantity of stiffening ring 3 supporting member 23 is set.Spacing connection strap 5 can guarantee that the distance between the backstay 2 adheres to specification.
Described supporting member 23 triangularities, at least one pin joint on it adopt latch 24 to connect.By taking off latch 24, the edge contraction of triangular support 23 can be got up, so that when dismounting is by the slurry of the string on the stiffening ring 3 hole.
Described supporting member 23 is provided with the flat connecting plate 4 of inserting.The flat connecting plate 4 of inserting prevents that stiffening ring is 3 protruding, sticks up, and stablizes the stiffening ring flatness.
Also be provided with shackle 25 on the described backstay 2.Shackle 25 can be disassembled into multistage with backstay 2, has alleviated the weight of single part, also is convenient to installation and removal.
Embodiment: a power station penstock internal diameter 6500mm, thickness of slab 24mm, tube coupling height 3000mm, arrange 3 layers of stiffening ring, ground floor stiffening ring 3 plate centers to tube coupling upper port is 500mm, second layer stiffening ring center to tube coupling upper port is 1500mm, and the 3rd layer of stiffening ring center to tube coupling upper port is 2500mm.Design has 16 string slurry holes on every layer of stiffening ring.
Stiffening ring spelling program is as follows: the obsolete material after (1) utilizes the steel pipe tube coupling to make adds man-hour by 16 backstays 2 of processing illustrated in figures 1 and 2, needs to consider stiffening ring 3 thickness of slab sizes.Maximum weight 10.6Kg in the part of single backstay 2, assembling back gross weight 24.8Kg.
(2) the steel pipe vertical seam welding is finished, and is beneficial to 16 stiffening ring string slurry hole sites that artificial or on-the-spot crane gear is installed on 16 backstays 2 steel pipe tube coupling 1.
Earlier backstay 2 upper parts are distributed in tube coupling 1 upper port, position by the concrete size of drawing, tighten the adjusting bolt 22 on the upper end hook 21, be connected with the upper end by the lower end of shackle 25 backstay 2, then supporting member 23 is all propped up, and locked with latch 24, just stiffening ring 3 can be installed behind flat slotting connecting plate 4 of installation and the spacing connection strap 5.
(3) utilize on-the-spot crane gear that stiffening ring 3 is hung to the supporting member 23 of backstay 2, utilize aids such as jack, sledgehammer to carry out the assembly unit of stiffening ring 3 and tube coupling 1 by design and code requirement, firm after stiffening ring 3 assembly units put in place with tube coupling 1 tube wall spot welding.
(4) after stiffening ring 3 installs, the latch on the supporting member 23 24 is extracted, supporting member 23 is folding, and separately shackle 25 is taken out the top and bottom of backstay 2 respectively from stiffening ring 3 string slurry holes.
(5) take off the utility model after, can carry out the welding between stiffening ring 3 and tube coupling 1 tube wall.The utility model is used for the spelling of next tube coupling stiffening ring immediately.
