Abstract
The utility model discloses a lifting device girder, which comprises a girder body and a connecting board disposed at the end of the girder body. The connecting board is provided with a connection hole connected with an end beam. The lifting device girder is characterized in that the girder body consists of an upper cover board, a lower cover board and two parallel arranged connecting web boards for connecting the upper cover board with the lower cover board, and the girder body is of an integral frame structure, and is integrally formed by cold pressing without splicing and welding. The lifting device girder has the advantages that the girder body is of the integral cold pressed frame structure, the formed girder scarcely has weld joints, production cost is reduced, also strength of the girder is increased, and the service life of the girder is prolonged.
Description
Technical field
The utility model relates to weight-lifting equipment, specifically relates to the accessory girder of weight-lifting equipment.
Background technology
The weight-lifting equipment girder of prior art is by connecting the I-shape construction that web is formed, it generally is to adopt multistage welding splicing to form, the patent of invention that is called clamping apparatus for vertical welding of single main beam group of crane for CN200910144441.8, name as the patent No. promptly provides the method for this splicing welding, relate to the clamping apparatus that a kind of vertical welding of single main beam group of crane is used specifically, weld so that implement the assembly unit of beam body by this equipment clamping.The table top of bench board is provided with the locking positioning mechanism of fixing single girder track and helps the detent mechanism of single girder two webs, strides on the bench board and is provided with door frame, and door frame is provided with the guiding stop gear that the control track contacts with two webs.As shown from the above technical solution, the present invention locks the track of single girder by locking positioning mechanism is set on table surface, detent mechanism is set helps two webs of single girder, provide application force to locate the planeness of web by the guiding stop gear again, and web and track are combined closely, the straightness accuracy and the camber of track have been guaranteed simultaneously, so that hoisting crane list main beam assembly unit welding.The girder of above-mentioned multistage welding may have quality problems when having welding processing all the time, also needs further reinforcement in its intensity and service life.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of weight-lifting equipment girder of easy to process, good integral strength long service life is provided.
The technical scheme that its technical matters that solves the utility model adopts is: this weight-lifting equipment girder comprises beam main body and the set connecting panel of beam body end, have on the connecting panel and end carriage bonded assembly connecting bore, it is characterized in that, described beam main body is by upper cover plate, lower cover and connect the connection web that the two two be arranged in parallel and constitute, the beam main body is the integral frame structure, for there not being the whole cold isostatic compaction of splicing welding.
As the further qualification of such scheme, described connection web and upper cover plate, the outside, lower cover junction also are provided with the reinforcement gusset.
The beneficial effects of the utility model are,
Adopt the cold isostatic compaction structure of global formation, and adopted amphisternous connection mode.Structure is more firm, need not welding splicing operation, and not because of the hidden danger that problems of welded quality caused, technology is simple, the high long service life of intensity.

Fig. 1 is a constructional drawing of the present utility model;
Fig. 2 is Fig. 1 embodiment side-looking constructional drawing;
Fig. 3 is the constructional drawing that the utility model is analysed and observe;
Description of reference numerals: 1. upper cover plate, 2. web, 3. lower cover 4, connecting bore 5, strengthen gusset 6 connecting panels.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
In the embodiment of Fig. 1-shown in Figure 3, weight-lifting equipment girder of the present utility model comprises beam main body and the set connecting panel 6 of beam body end, have on the connecting panel 6 and end carriage bonded assembly connecting bore 4, this connecting bore 4 be about each 3 be arranged side by side, the beam main body is by upper cover plate 1, lower cover 3 and connect the connection web 2 that the two two be arranged in parallel and constitute, the beam main body is the integral frame structure, for there not being the whole cold isostatic compaction of splicing welding, described connection web 2 and upper cover plate 1, the outside, lower cover 3 junctions also is provided with strengthens gusset 5, and this gusset 5 can be provided with at interval as required according to circumstances.
The utility model is not limited to the foregoing description; Described simple replacement to said structure all should be covered by in the protection domain of the present utility model.
