Description

Microcomputerized control reinforced concrete pile, pipe, bar framework of steel reinforcement seam welder

The utility model discussion be the welder of a kind of reinforced concrete pile that is used for reinforced concrete product, pipe, bar framework of steel reinforcement, belong to the welding class.

Prestressed concrete pipe pile is a kind of hollow garden column type precast concrete that adopts pretensioned prestressing technology and centrifugal formation method to make through steam-cured still high-temperature steam curing, because it is strong that it has a bearing capacity of single pile, cost is low, easy to use, be convenient to advantages such as standardization, more and more be subject to people's attention.In the past, during the framework of steel reinforcement of China in making concrete tubular pile, water pipe, electric pole, adopt manual colligation mostly or with the preparation method of artificial welding, so not only labour intensity is big, production efficiency is low, and the quality of product can not get assurance.Since the reform and opening-up, particularly in recent years, along with steering a steady course of economy, driven the harbour, bridge, causes such as skyscraper flourish, to the demand of reinforced concrete pipe pile year by year altar add, to " stake " quality requirements also more and more higher, therefore operation is produced framework of steel reinforcement and is not only existed can not satisfy aspect " amount " and build the needs that develop by hand, the more important thing is that " matter " can't reach the engineering index, thereby the main production equipments of developmental research and production reinforced concrete pipe pile---strong concrete pipe pile reinforcing bar skeleton seam welder will play a positive role to the development of garden cylindricality concrete precast pile.

According to our market survey and data-searching, the present domestic producer that does not still produce strong concrete pipe pile reinforcing bar skeleton seam welder.Flourish along with construction business, Chang Yong PC stake in the past can not adapt to the construction requirement of modern high-rise building and deepwater wharf, the PHC stake is just in China's development and application, needs for full construction, the city, south was once introduced two covers and was produced the production line of PHC stake, the key equipment of this production line just has the automatic weld of framework of steel reinforcement, introduction of production line not only will be spent a large amount of foreign exchanges of country, and equipment is too fat to move, troublesome poeration, maintenance difficult be the more important thing is the contradiction that also exists introducing equipment only to be fit to use imported material.

The objective of the invention is provides a kind of microcomputerized control of using to society, realize, solder joint distortionless to framework of steel reinforcement firmly, little big, the no rosin joint of reinforced steel bar strength loss and leak strong concrete stake, pipe, the bar framework of steel reinforcement seam welder that weldering also can be fit to various materials.

The utility model seam welder, it is by cylinder, fixed electrode, and float electrode (is promptly welded arm, down together), for the muscle frame, ring muscle dish, folder muscle sheave, compositions such as welding signal generator and microcomputerized control circuit, fixed electrode places a side of cylinder, and the weldering arm is fixed on the cylinder, is placed in the cylinder for muscle, be fixed on the opposite side of cylinder, ring muscle dish places the same side of fixed electrode, and folder muscle sheave is fixed on the dolly, it is characterized in that: cylinder, the weldering arm, for the muscle frame, ring muscle dish, the garden heart of folder muscle sheave is all on same center line; Vertical muscle frame will be indulged the axially-aligned of muscle along fixed electrode, and the vertical muscle horizontally tracting of folder muscle sheave folder, ring muscle dish will encircles muscle and deliver on the fixed electrode to twine with vertical muscle and contact, and weld upper-arm circumference and rotate and weld around fixed electrode; Welding signal generator and cylinder rotate synchronously.The master control borad that the microcomputerized control welding circuit is made up of single-chip microcomputer and some control elements, photoelectrical coupler, power amplification circuit, synchronizing signal power supply and welding major loop and alternative route, the time set device is formed, and master control borad is by single-chip microcomputer, latch, memory, buffer, driver, converter (as Fig. 3. I) form, it receives welding signal, and to the size of welding current, the time and interference etc. is carried out computing, handle, export the constant electric current then, it is characterized in that: photoelectrical coupler by photoelectric tube U1 and some electronic components form (Fig. 3. II) the signal a that comes from the welding signal generator, b is serially connected in the U1 input, 1 pin of U1 output termination master control borad; The time set device is made up of diode and driver chuck switch, and its output connects master control borad 7 pin; Comparison circuit is by variable resistor and change-over switch, and rectification circuit is formed, and it receives the feedback current of welding major loop, with setting electric current or comparison electric current by the central point O of change-over switch, connects master control borad 6 pin; The synchronizing signal power supply is made up of rectification circuit and triode etc., it will be after treatment satisfactory master control borad working power, cpu power respectively correspondence connect master control borad 3 and 4,5 pin are ground wire; Power amplification circuit (Fig. 3. III) by controllable silicon 3CT, compositions such as photoelectric tube U2, master control borad are handled, after the computing signal to connect the U2 input by 2 pin auspicious, the output of U2 meets the D of 3CT, F pin, output C, the G of power amplifier meet C ', the G ' of welding major loop KS; The welding major loop (Fig. 3. V) by KS, B1, CT and R6 form, and primary current is by feeding back to the input of comparison circuit with CT and the R6 two ends that connect, the secondary A of B1, B take over a job moving electrode and fixed electrode.

The utility model adopts welding mechanism and ring muscle dish to rotate in the same way, framework of steel reinforcement level vertically is pulled, the ring muscle twines the constant feed, welding is followed the tracks of in the rotation of weldering arm, solved the big more contradiction of the long more torsion resistance of framework of steel reinforcement in the past, make the good integrity of framework of steel reinforcement, the fast and vertical rigidity of soft tissues degree loss of moulding is little.Computer control welding circuit and lever weldering arm have guaranteed that pipe, bar, each solder joint to all size can both do welding accurately and reliably, and can get rid of to leak and weld and the mistake weldering, in addition, that the utility model also has is simple and reasonable for structure, Installation and Debugging are easy, dependable performance, easy to maintenance, low cost and other advantages.
