Abstract
The utility model discloses a tooling for assembling and welding transition joints of a tower-type crane. The tooling comprises two support bases and is characterized in that a horizontal central shaft is fixedly connected to each support base; a template is mounted on each central shaft through a bearing; the two templates are connected with each other through two or more connecting rods; four sets of lug plate positioning clamping plates are fixedly arranged on each template; the positioning clamping plates on the two templates are in one-to-one correspondence; and positioning pin holes corresponding to the lug plates are formed on each set of lug plate positioning clamping plates. The tooling with accurate lug plate positioning and good interchangeability greatly improves the working efficiency.
Description
Technical field
The utility model relates to a kind of assembly welding frock that is used for the derrick crane transition segment.
Background technology
Transition segment is the important structure part and the stressed member of tower machine, its structure as shown in Figure 1, comprise four Dan Zhizhu strings of setting up jointly by angle steel side 9, six cuboid frameworks 10 that face is become with the channel-section steel assembly welding by angle steel, the two ends of Dan Zhizhu string 9 are welded with and connect otic placode 11 and 12, otic placode 11 and 12 is provided with pin-and-hole, so transition segment upper and lower, forward and backward is provided with corresponding connection otic placode, transition segment connects the tower cap by connecting on the otic placode, the preceding crane arm that connects, the back connects counter-jib, under connect lower support, the position that therefore connects pin-and-hole on the otic placode is just very crucial; Transition segment is by first assembly welding truss, locatees the otic placode assembly welding on truss by line more at present, or manufacture with it with other parts, because line location or the mode that manufactures are located inaccurate or are had randomness, the parts that cause every tower machine and transition segment to manufacture all can not exchange, as parts damages, must manufacture again, make troubles, and working (machining) efficiency is low to the user.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of assembly welding frock of derrick crane transition segment is provided, and it has otic placode accurate positioning, advantage that interchangeability is good, and significantly improves working (machining) efficiency.
For achieving the above object, the assembly welding frock of derrick crane transition segment of the present utility model, comprise two bearings, the central shaft that it is characterized in that the level that on each bearing, also connects firmly, by bearing one template is installed on the every central shaft, two templates link to each other by the connecting rod more than two or two, are installed with four groups of otic placode positioning splints on every template, positioning splint on two templates is corresponding one by one, and every group of otic placode positioning splint is provided with the dowel hole corresponding with otic placode.
During assembly welding, the otic placode at four Dan Zhizhu string two ends is positioned among the positioning splint corresponding on two templates, alignment pin passes the corresponding positioning splint and the pin-and-hole of otic placode simultaneously, part such as lead frame, guard bar again, not only otic placode accurate positioning, interchangeability are good, and rotatable two templates during welding, only need carry out downhand welding, be convenient to operation, and significantly improve working (machining) efficiency.
Description of drawings
Fig. 1 is the front view of transition segment.
Fig. 2 is the front view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 2, the assembly welding frock of this derrick crane transition segment, comprise two bearings 1, on each bearing 1, also connect firmly the central shaft 2 of a level, by bearing one template, 3, two templates 3 are installed on the every central shaft 2 and link to each other, on every template 3, be installed with four groups of otic placode positioning splints 5 by two connecting rods 4, positioning splint 5 on two templates 3 is corresponding one by one, and every group of otic placode positioning splint 5 is provided with the dowel hole corresponding with otic placode 6.
During assembly welding, the otic placode at four Dan Zhizhu string 7 two ends is positioned among the positioning splint 5 corresponding on two templates 3, alignment pin passes the corresponding positioning splint 5 and the pin-and-hole of otic placode simultaneously, parts such as lead frame 8, guard bar again, not only otic placode accurate positioning, transition segment interchangeability are good, and rotatable two templates 3 during welding, only need carry out downhand welding, be convenient to operation, and significantly improve working (machining) efficiency.
