Abstract
The utility model discloses a tower crane and tower cap molding tool. The tower crane and tower cap molding tool comprises a molding frame, the side projection of which is L-shaped; first limiting support seats which are in one-to-one correspondence with the lower lug plates of a tower cap are fixed on the inner side surface of the vertical part of the L-shaped molding frame; a second limiting support seat corresponding to the upper lug plate of the tower cap is arranged at the end part of the horizontal part of the L-shaped molding frame; each of the first limiting support seats and the second limiting support seat is formed by two limiting plates which are arranged at an interval; symmetric through holes which are concentric with the fixed hole of the corresponding lug plate are formed in each limiting plate; a first support block is fixed at the lower part of each first limiting support seat; a second support block is arranged on the inner side the second limiting support plate. According to the tower crane and tower cap molding tool, all lug plats are positioned at one time, a large amount of time is saved, the position degree of each lug plate can be guaranteed, the product difference caused by the existing technology is eliminated, and the product quality and the production efficiency are improved.
Description
Technical field
The utility model relates to tower crane and manufactures field, is specifically related to a kind of tower machine tower cap forming frock.
Background technology
In recent years, along with the rapid growth of China's economic construction, capital construction scale constantly expands, being on the increase of high-building construction particularly, and the application of tower crane is more and more extensive.Tower machine tower cap consists of main zeugopodium and otic placode welding, prior art is on ground, to amplify sample to adopt joining of monolithic moulding to make mode processing column cap, consumes manpower, and the production cycle is long, and can not accurately guarantee the fixed position of otic placode and the relative position of otic placode and main zeugopodium, the quality of product there are differences.
Summary of the invention
?the utility model discloses a kind of tower machine tower cap forming frock, accurate positioning, process laborsaving, improve production efficiency and product quality greatly.
The utility model is achieved through the following technical solutions:
A kind of tower machine tower cap forming frock, comprise the forming supporter that side-looking projection is L-shaped, the medial surface of described L shaped forming supporter vertical portion is fixed with and tower cap lower ear plate the first spacing bearing one to one, the end of described L shaped forming supporter horizontal part is provided with the second spacing bearing corresponding with tower cap upper ear plate, described first, the positioning plate that the second spacing bearing arranges by two block gaps forms, on described positioning plate, offer the symmetrical through hole concentric with the fixed orifice of corresponding otic placode, the below of described each the first spacing bearing is all fixed with the first back-up block, the inner side of described the second spacing bearing is provided with the second back-up block.
The further improvement project of the utility model is that described the second back-up block is welded on the upper surface of described L shaped forming supporter horizontal part.
The utility model further improvement project is, the lateral surface of described L shaped forming supporter vertical portion is provided with hound, and the bottom of described hound is fixedly connected with the base plate that is fixed on bottom, described L shaped forming supporter vertical portion.
The utility model further improvement project is that the aperture of described symmetrical through hole is identical with the fixed orifice of the upper and lower otic placode of tower cap, is inserted with a bearing pin coordinating with its aperture in described symmetrical through hole.
The utility model further improvement project is, the fixed orifice of the upper and lower otic placode of tower cap is with the symmetrical through hole of corresponding positioning plate by described bearing pin coaxial positioning, and the bottom of described upper and lower otic placode is respectively by the second, first back-up block support limit of correspondence.
Compared to the prior art the utility model has the following advantages:
The utility model is simple in structure, during use, first take out the bearing pin on positioning plate, upper and lower otic placode is placed between positioning plate and makes its fixed orifice concentric with the through hole of positioning plate, insertion bearing pin location, otic placode is fixing under the combined action of bearing pin and back-up block, then main zeugopodium is placed on forming supporter and makes its corresponding position and otic placode laminating, finally weld and then moulding tower cap.The all otic placodes of the utility model one-time positioning, have not only saved a large amount of time, and can guarantee the position degree of otic placode, stop prior art and produce the product differentiation causing, and improve product quality and production efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model schematic side view.
Fig. 2 be in Fig. 1 A to schematic diagram.
The specific embodiment
A kind of tower machine tower cap forming frock as shown in Figure 1, 2, comprise the L-shaped forming supporter of side-looking projection 1, the medial surface of described L shaped forming supporter 1 vertical portion 11 is fixed with and tower cap lower ear plate 2 the first spacing bearing 3 one to one, and the end of described L shaped forming supporter 1 horizontal part 12 is provided with the second spacing bearing 31 corresponding with tower cap upper ear plate 21.
Wherein, the positioning plate 4 that described first, second spacing bearing 3,31 arranges by two block gaps forms, on described positioning plate 4, offer the symmetrical through hole 41 concentric with the fixed orifice of corresponding otic placode, the aperture of symmetrical through hole 41 is identical with the fixed orifice of the upper and lower otic placode 21,2 of tower cap, is inserted with a bearing pin 7 coordinating with its aperture in symmetrical through hole 41.The inner side that the below of each the first spacing bearing 3 is all fixed with the spacing bearing 31 of the first back-up block 5, the second is provided with the second back-up block 51, and concrete is the upper surface that the second back-up block 51 is welded on L shaped forming supporter 1 horizontal part 12.The fixed orifice of the upper and lower otic placode 21,2 of tower cap and the symmetrical through hole of corresponding positioning plate 4 41 be by bearing pin 7 coaxial positioning, and the bottom of described upper and lower otic placode 21,2 is respectively by the second, first back-up block 51,5 support limit of correspondence.
In the present embodiment, the lateral surface of described L shaped forming supporter 1 vertical portion 11 is provided with hound 6, and the bottom of described hound 6 is fixedly connected with the base plate 61 that is fixed on 11 bottoms, described L shaped forming supporter 1 vertical portion.
