Abstract

A welding device for tower body standard knot steps comprises a lower base seat, an upper base seat, fixing devices, a fixed reinforcing frame, support frames, positioning plates, positioning sleeves, and positioning bolts. The lower base seat is positioned in a bottom portion of the whole welding device. A bottom portion of the upper base seat is fixedly connected with an upper portion of the lower base plate. The positioning bolts transversely penetrate through the upper base seat and fix the steps. The positioning sleeves transversely penetrate through the upper base seat and are tightly contacted with arc surfaces of front ends of the steps. The fixed reinforcing frame transversely penetrates through the upper base seat and fixes steel pipes at two sides of the upper base seat with the fixing devices. The support frames used for supporting the steel pipes are respectively fixed at two sides of the lower base seat. The welding device for the tower body standard knot steps has the advantages that: the welding device for the tower body standard knot steps has a simple structure, the non-synchronization of the steps at two sides of a main chord member can be avoided, the welding performance of step plates and the main chord member can be guaranteed, and the production efficiency is improved.

Description

The body of the tower standard knot welding tooling of marking time

Technical field

This utility model relates to a kind of welding tooling, and the welding tooling that particularly a kind of body of the tower standard knot is marked time belongs to body of the tower manufacturing technology field.

Background technology

Very universal in the middle of the colleague from rising the type derrick crane; The processing welding of standard knot is the manufacturing difficult point of this crane; Because the jacking required distance is accurate in standard knot jacking process; General processes goes out marks time that the mark time welding reliability of nonsynchronous phenomenon and step plate and main swing arm of both sides can to occur not high, causes standard knot in the jacking process, deviation to occur, influences the security of complete machine.

Summary of the invention

Goal of the invention: the purpose of the utility model provides a kind of simple in structure, and the body of the tower standard knot that can guarantee the welding quality of marking time of the body of the tower standard knot welding tooling of marking time.

Technical scheme: a kind of body of the tower standard knot welding tooling of marking time; Comprise down the basis seat, go up the basis seat, fixture, fixedly hog frame, bracing frame, location-plate, positioning sleeve and bolt; Said basis down seat is positioned at whole frock bottom; Said bottom of going up the basis seat is fixedly connected with seat top, following basis, and said bolt crosses the basis seat and fixedly marks time, and said positioning sleeve crosses basic seat and closely contacts with the arc surface of the front end of marking time; Said fixedly hog frame crosses basis seat and the fixing steel pipe of going up seat both sides, basis of fixture; The bracing frame that is used for supporting steel pipe is individually fixed in down seat both sides, basis.At first will mark time and fix and accurate location through bolt and positioning sleeve; And then through bracing frame steel pipe flatly is placed on basis seat both sides respectively, at last through fixture and fixedly hog frame the steel pipe location is guaranteed that the distance between two steel pipes meets the requirements.

For the distance between the depth of parallelism that guarantees two steel pipes and two steel pipes meets the requirements; Said location-plate comprises first location-plate and second location-plate; Said first location-plate is fixedly connected with last basis seat and is positioned at the bracing frame top, and said second location-plate is in fixture with fixedly between the hog frame.

Beneficial effect: the utility model is simple in structure, can avoid the pedal of main swing arm both sides nonsynchronous phenomenon to occur, and guarantees the welding performance of step plate and main swing arm, has improved production efficiency.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described further.

As shown in the figure; A kind of body of the tower standard knot welding tooling of marking time; Comprise down basis seat 1, go up basis seat 2, fixture 3, fixedly hog frame 4, bracing frame 5, location-plate 6, positioning sleeve 7 and bolt 8, said basis down seat 1 is positioned at whole frock bottom, the said bottom of basis seat 2 of going up is fixedly connected with basic 1 top down; Said bolt 8 crosses basis seat 2 and fixedly marks time 9, and said positioning sleeve 7 crosses basic 2 and closely contacts with the arc surface of 9 front ends of marking time; Said fixedly hog frame 4 crosses basis seat 2 and the fixture 3 fixing steel pipes 10 of going up seat 2 both sides, basis; The bracing frame 5 that is used for supporting steel pipe 10 is individually fixed in down seat 1 both sides, basis.At first will mark time and 9 fix and accurately locate through bolt 8 and positioning sleeve 7; And then through bracing frame 5 steel pipe 10 flatly is placed on basis seat 2 both sides respectively, at last through fixture 3 and fixedly hog frame 4 steel pipe 10 location are guaranteed that the distance between two steel pipes 10 meets the requirements.

For the distance between the depth of parallelism that guarantees two steel pipes 10 and two steel pipes 10 meets the requirements; Said location-plate 6 comprises first location-plate 61 and second location-plate 62; Said first location-plate 61 is fixedly connected with last basis seat 2 and is positioned at bracing frame 5 tops, and said second location-plate 62 is in fixture 3 with fixedly between the hog frame 4.
