Abstract
The invention discloses a detachable sleeve frame structure of a tower crane. The structure is mainly composed of a four-side rectangular frame structure composed of main ribs (1), a cross beam (2) and web rods (4); in each side, the main ribs (1) are located on the two sides respectively and connected through flanges (B) to form a two-segment type; the two ends of each cross beam (2) are connected to lug plates of the main rib (1) on the corresponding side through pin shafts, joint plates are installed in the centers of the cross beams (2) arranged at intervals, and four lug plates (F) are installed on each joint plate; and one end of each web rod (4) is connected to the lug plates of the main rib (1) on the corresponding side through pin shafts, and the other end of each web rod (4) is connected to the corresponding joint plate lug plate (F). The detachable sleeve frame structure has the beneficial effects that welding and machining of a sleeve frame are convenient, difficulty in the installing process is reduced, transportation is facilitated, cost of cars for delivering goods is saved, and occupied space is reduced.
Description
Technical field
The present invention relates to a kind of removable cover shelf structure, be particularly useful for tower machine.
Background technology
Stock is made up of main string and crossbeam, web member, bear the truss structure of vertical power when tower machine upper is increased or reduced and moment of flexure, current tower crane stock profile is a rectangular frame structure form, as shown in Figure 1, crossbeam one is directly welded on main limb one, one end of web member one in plane is welded on main limb one, one end is welded on the cross beam gusset plate at A place, form mutually one side thus, simultaneously the crossbeam one of adjacent surface, web member one are also welded on one of them main limb of this face, form the fixing framework in four directions as shown in Figure 2.Because stock mainly adopts welding to be spliced, welding processing easily causes tetrahedron to be out of shape, asymmetric, installs difficulty, and four square frame entruckings difficulties during transport, takes up room large, increases traffic cost.
In the industry the scheme improving above-mentioned phenomenon is generally at present: the rectangular frame structure form of stock remains unchanged, is designed to three and fixes, a detouchable form.As above shown in Fig. 4, Fig. 5, part 41 is for connecting orifice plate, and part 42 is crossbeam, and part 43 is web member, and connect orifice plate 41 and be welded on crossbeam 42 two ends, web member 43 is welded on crossbeam 42, is spliced into an entirety, as one side.The welding of its excess-three face is spliced into as shown in Figure 5, when vertical tower is installed, connects orifice plate 41 and combines with part 44, hole, part 45 place one, hole two, be bolted and be integrated.During entrucking delivery, pull down detachable face as shown in Figure 4.
But above-mentioned improving countermeasure also exists following shortcoming in tower crane installation and transportation process: 1, stock is on four sides for welding is spliced, and welding processing easily causes tetrahedron to be out of shape, asymmetric, difficulty is installed; 2, stock four square frame entrucking difficulty during delivery transport, takes up an area space greatly, increases vehicle transportation cost.
Summary of the invention
For above-mentioned existing technical matters, the invention provides the removable cover shelf structure of a kind of tower machine, to facilitate stock to weld and processing, reduce the degree of difficulty in installation process, save delivery car cost, reduce and take up an area space.
For achieving the above object, the invention provides the removable cover shelf structure of a kind of tower machine, primarily of main limb, crossbeam and web member composition four sides rectangular frame structure; In every one side, described main limb stands on both sides respectively, is the two-segment type by Flange joint; Described crossbeam two ends are connected on the main limb otic placode of respective side by bearing pin, and spaced crossbeam center is provided with gusset plate, each gusset plate are provided with four otic placodes; Described web member one end is by pinned connection on the main limb otic placode of respective side, and the other end is connected to corresponding gusset plate and goes up in one's ear.
Further, also comprise cat ladder mounting rail, be arranged on and connect same gusset plate and between two web members of crossbeam homonymy.
The rectangular frame structure form of stock of the present invention remains unchanged, and integrated connection mode changes bearing pin into by welding, bolt connects.The main limb of stock divides two joints, is linked together by flange, and pinned connection form is made at crossbeam, the web member two ends of composition cover shelf structure, and in every one side of stock, each crossbeam web member forms one side by pinned connection.During entrucking delivery, stock is disassembled into single main limb, web member form completely, and binding delivery, saves space in a large number.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 3, for the deficiencies in the prior art, improve install, the convenience of delivery, the present invention primarily of main limb 1, crossbeam 2, cat ladder mounting rail 3 and web member 4 form four sides rectangular frame structure; In every one side, described main limb 1 stands on both sides respectively, is the two-segment type connected by flange B; Described crossbeam 2 two ends are connected on main limb 1 otic placode of respective side by bearing pin, and spaced crossbeam 2 center is provided with gusset plate, each gusset plate is provided with four otic placode F; Described web member 4 one end is by pinned connection on main limb 1 otic placode of respective side, and the other end is connected to corresponding gusset plate in one's ear on F; Described cat ladder mounting rail 3, is arranged on and connects same gusset plate and between two web members 4 of crossbeam 2 homonymy.
During the invention process, installing/dismounting principle is as shown in Figure 6: the main limb 1 of stock is divided into two joints, be bolted together by flange B, pinned connection form is made at crossbeam 2 two ends, by A otic placode by pinned connection on the main limb 1 in both sides, pinned connection form is made at web member 4 two ends, one end by A otic placode by pinned connection on main limb 1, one end by otic placode F by pinned connection on crossbeam 2, cat ladder mounting rail 3 is arranged between two web members 4 by arc bolt hole, E place.During entrucking delivery, the main limb of composition cover shelf structure, crossbeam, web member and cat ladder mounting rail etc. are all pulled down, as single object, bundles entrucking delivery.
Visible, the present invention in actual applications, facilitates welding and the processing of stock, reduces the degree of difficulty in installation process, has saved delivery car cost, decreases and takes up an area space, can fill more object in limited space.By the application of this technology, the safety in installation process and convenience can be improved preferably, reduce delivery traffic cost to a great extent simultaneously.
