Abstract
The utility model discloses a kind of assembly tooling, especially a kind of derrick crane sliding bottom steel construction assembling device.The utility model provides one and goes out tire and be easy to derrick crane sliding bottom steel construction assembling device, comprises angle bearing and center support; Described angle bearing settlement has four, and four angle bearings lay respectively on the corner of rectangle, and the assembling axis of angle bearing overlaps with the diagonal of rectangle; Described angle bearing is stepped, every grade of ladder is provided with assembling lining, and described stair-stepping angle bearing outwards raises gradually by rectangle; Described center support is positioned at the center of rectangle.By adopting stair-stepping angle bearing, up-small and down-big workpiece can be made to assemble conversely, after workpiece assembles, directly can take out workpiece from the bearing of stair-stepping angle, what such reverse thinking can solve workpiece goes out a tire difficult problem, need not dismantle angle bearing simultaneously, save a large amount of man-hours.
Description
Technical field
The utility model relates to a kind of assembly tooling, especially a kind of derrick crane sliding bottom steel construction assembling device.
Background technology
The sliding bottom structure that adopts of the climbing structure of more domestic large-scale derrick cranes (standard knot is round steel for connecting otic placode and main string) is generally complicated at present, and its each cylinder lever connecting rod, corresponding coupling part and steel construction thereof are space structure and size.Therefore, technological equipment must be adopted to ensure its correlation space structure and size in the process of assembling sliding bottom structure.Due to the particularity of sliding bottom structure, adopt traditional formal dress mode to assemble and (in assembling sliding bottom steel construction process, namely press its steel construction of assembling of the installation site relationship consistency of sliding bottom upper and lower surface in relative to tower crane lifting structure, be formal dress), the design of its technological equipment, manufacture, installation and debugging and later stage use procedure thereof are all very complicated and loaded down with trivial details, difficulty is large, labour intensity is high, easily produces unnecessary following problem:
1, go out tire difficulty, labour intensity is large, and efficiency is low:
Workpiece needs the face, hole of location, distributes in positive truncated rectangular pyramids, upper little, greatly lower.After assembling, when going out tire, whole positioning seat must be withdrawn from.Again restore and positioning seat is installed, use in order to assembling second workpiece.Waste time and energy.
2, the compact principle of process layout is not met:
Tool structure is huge, occupies mounting plate area wide.
3, position stability is poor, and location seat structure is complicated:
Planar central place on workpiece, the location in two holes and face, must adopt the mode that locating surface overturns, and can go out tire.Due to needs upset, then complex structure, huge; Use bothersome, and not as fixed locating surface stable accuracy.
Utility model content
Technical problem to be solved in the utility model is to provide one and goes out tire and be easy to derrick crane sliding bottom steel construction assembling device.
The utility model solves the derrick crane sliding bottom steel construction assembling device that its technical problem adopts, and comprises angle bearing and center support; Described angle bearing settlement has four, and four angle bearings lay respectively on the corner of rectangle, and the assembling axis of angle bearing overlaps with the diagonal of rectangle; Described angle bearing is stepped, every grade of ladder is provided with assembling lining, and described stair-stepping angle bearing outwards raises gradually by rectangle; Described center support is positioned at the center of rectangle.
Further, also comprise collateral seat, described collateral seat is provided with two, is separately positioned on the center on relative two limits of rectangle.
Further, described center support is inverted L-shaped, and described center support is provided with two and is oppositely arranged.
Further, described angle bearing be three grades stepped.
The beneficial effects of the utility model are: by adopting stair-stepping angle bearing, up-small and down-big workpiece can be made to assemble conversely, after workpiece assembles, directly can take out workpiece from the bearing of stair-stepping angle, what such reverse thinking can solve workpiece goes out a tire difficult problem, angle bearing need not be dismantled simultaneously, save a large amount of man-hours.Meanwhile, collateral seat can also be adopted to carry out auxiliary positioning, make the assembling of workpiece more accurately reliable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The terminological interpretation that the utility model relates to is as follows: go out tire, after having referred to welding equipment, exits frock; Formal dress, refers to assemble by the duty of sliding bottom; Upside-down mounting, refers to by the inverted state assembling of sliding bottom.
As depicted in figs. 1 and 2, the utility model comprises angle bearing 1 and center support 2; Described angle bearing 1 is provided with four, and four angle bearings 1 lay respectively on the corner of rectangle, and the assembling axis of angle bearing 1 overlaps with the diagonal of rectangle; Described angle bearing 1 is stepped, every grade of ladder is provided with assembling lining 4, and village's cover 4 is provided with installing hole, in order to install the parts of workpiece, so that workpiece assembling; Described stair-stepping angle bearing 1 outwards raises gradually by rectangle, and namely angle bearing 1 is higher than its inner ring in the outer ring of rectangle; Described center support 2 is positioned at the center of rectangle.Because angle bearing 1 is stepped, angle bearing 1 be traditionally arranged to be three grades stepped, as shown in Figure 3, and stair-stepping angle bearing 1 outwards raises gradually by rectangle, therefore the assembly space of four angle bearing 1 formation is reverse pyramid, workpiece up-small and down-big so just in time can upside down and assemble in this assembling device, after having assembled, workpiece can not be subject to again the stop of this assembling device, tire can be gone out smoothly, without the need to taking this assembling device apart, which improves operating efficiency, its simpler assembly manipulation also can make rigging error reduce.This assembling device adopts and is flip-chip mounted sliding bottom workpiece, obviously than traditional formal dress advantageously, more meets the shape and structure feature of workpiece self.
In order to make assembling more accurate, as shown in Figure 2, also comprise collateral seat 3, described collateral seat 3 is provided with two, is separately positioned on the center on relative two limits of rectangle.Collateral seat 3 is also provided with syndeton, for stable connection workpiece part, workpiece can be supported in side when assembling.
Concrete, as shown in Figure 4, described center support 2 is in inverted L-shaped, and described center support 2 is provided with two and is oppositely arranged.The top of center support 2 is provided with installing hole, can the centre of sliding bottom be supported like this.
