Abstract
A crane beam rail fixing device belongs to the technical field of crane rail equipment, is used for fixing a crane beam rail, and avoids damage when the crane beam rail is impacted. The technical scheme includes that the crane beam rail fixing device comprises bases, compression plates and fastening bolts, the bases are disposed at intervals in the direction of the crane beam rail, the front ends of the bases are abutted to and welded to the lower edge of the rail, two vertical bolt holes are arranged on each base and matched with the fastening bolts, one end of each compression plate is fixed on the corresponding base by the aid of the fastening bolts while the other end of the compression plate is pressed to the upper surface of a rail holder, the base is 40-45mm thick, and each compression plate is 20-25mm thick. Transverse displacement of the rail is limited by the aid of the inner sides of the bases, the compression plates are purely used for limiting longitudinal displacement of the rail, pressing force of each compression plate is enlarged by the aid of two bolts, the bases are directly drilled and internal threads are processed in the drilled holes while original nuts are omitted, and thereby use of components is reduced to the maximum extent.
Description
Technical field
The utility model relates to a kind of real abdomen formula crane girder and track that is used for industrial premises and open-air trestle and is connected and fixed device, belongs to the crane runway equipment technical field.
Background technology
Crane is an imperative equipment in commercial production and the lifting transportation, and when crane was worked, track can not have horizontal and vertical moving.Usually, crane girder and track are connected with two kinds of base models: a kind of is traditional to pass pressing plate and track is fixed in the crane girder top flange with bolt, and this method is most common form, and is easy to assembly, but dismounting trouble when changing track.Another kind is that rail pressing device is welded on track fixed form on the crane girder top flange, and this mode also is that a lot of in recent years units take.
When the large span heavy duty crane is worked, because all multifactor influences such as cart gauge deviation, the driving of cart bilateral is asynchronous, overhead traveling crane girder amount of deflection changes, the dolly brake is frequent, often cause cart wheel face wheel along violent friction taking place, promptly " gnaw " phenomenon with track.According to test, the transverse horizontal power that big Car Track bears under " gnawing " state under this state, though be unlikely to cause the destruction of track and crane girder brake system, can make fixture of the rail be damaged greater than the design level characteristic value of load.Adopt above-mentioned first kind of connection mode as track, track is bigger because of being subjected to the crane horizontal force, and the displacement of track partial lateral often takes place, the track lower flange " rides up to " on the backing plate of attaching parts when serious, even causing the track fracture, the maintenance work amount is very big, production is caused have a strong impact on.Gnaw serious position and select for use the rail pressing device of various ways to be installed in this situation, effect is all not obvious.The reason that produces this situation mainly is that base designs thickness all was not more than track lower flange thickness in the past, is difficult to resist the impact of transverse horizontal power and is damaged, and it is very necessary therefore the crane girder device for fixing running tracks being improved.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of cross travel and longitudinal travel, increase thrust that can limit track, make it to be enough to resist the impact of transverse horizontal power and the crane girder device for fixing running tracks that is unlikely to be damaged.
The technical scheme that solves the problems of the technologies described above is:
A kind of crane girder device for fixing running tracks, it is made up of base, pressing plate, binding bolt, its improvements are, base is along crane girder track alignment pitch arrangement, and base front end and side, track lower flange hold out against, and is welded on the track girder top flange on the plane, on each base, be arranged with 2 vertical screws, binding bolt and screw are complementary, and pressing plate one end is fixed on the base by binding bolt, and the other end is pressed in the upper surface of track lower flange.
Above-mentioned crane girder device for fixing running tracks, the thickness of described base are 40-45mm, and the thickness of pressing plate is 20-25mm, and the binding bolt specification is M22 * 60.
The utility model limits the cross travel of track with the base inboard, pressing plate is used for limiting the longitudinal travel of track merely, increase thrust with 2 bolts, pressing plate front portion and track lower edge contact point are more near orbit centre, avoided causing the pressing plate damage because of track displacement, direct perforation processing negative thread and cancel original nut on base has reduced the member consumption to greatest extent.
