Abstract
The utility model relates to a crane orbit fixator, is composed of a base seat, an upper locking plate arranged on the base seat, a plain washer which is arranged between the base seat and the upper locking plate and is arranged with adjusting keys on the upper locking plate and a spring washer, T-shaped bolts which orderly penetrates the base seat, the upper locking plate, the plain washer and the spring washer, and nuts. The utility model is characterized in that the upper locking plate is arrange with two bolt holes, the middle of the upper locking plate is provided with a reinforcing rib with a stronger strength to form a ' ' structure, the base seat is arranged to be a ' concave ' shape, the middle part is arranged with a port which matches the reinforcing rib on the upper locking plate, two raised heads are respectively arranged with a bolt hole, the T-shaped bolt successively penetrates the base seat, the bolt hole in the upper locking plate, the plain washer and the spring washer, and is fastened by a nut. The utility model has advantages that due to the structure adopted, the center of gravity of the upper locking plate decreases, the rigidity thereof improves, not only the lateral force of the crane is effectively resisted, but also the transmission of the lateral force in the upper locking plate is in favor, a stable and safe operation of a heavy crane is ensured.
Description
Technical field
The present invention relates to the crane runway fixer, is crane runway to be fixed on device on the crane girder what factory floor used.
Background technology
Development along with major industry, in metallurgical industry, power industry, heavy-duty machinery manufacture, large tonnage crane is generally adopted, and operates steadily in order to ensure crane, and manufacturer requires the interior crane of factory building that track adjusting wheel will be arranged, promptly perpendicular to the horizontal wheel on track top, when crane operation steadily the time or when having hung the weight brake, track adjusting wheel is just braked the inclination of car body, to guarantee the crane reliability service, and track adjusting wheel is given track top one side force, and this side force is very big.At present on this crane girder fixedly the rail device adopt base mostly, be buckled in the last clamp on the base, and being provided with between base and the last clamp adjusted key and formed between being arranged on, and with its with T type screw bolt passes base, to go up clamp fastening with flat gasket and spring washer, nut.Though the fixer of this structure is to reaching crane girder to the vertical wheel load of crane, and the side force of crane passed to the crane brake system, reach the fixedly effect of rail, but to the large-tonnage crane, the crane of hoisting capacity more than 400 tons is because the side force of its track adjusting wheel reaches 300-500KN, domestic in addition its height to width ratio of QU type track is 1: 1, the track center of gravity is higher relatively, and above-mentioned device for fixing running tracks can not satisfy operating needs, guarantees the steady reliability service of crane.
Summary of the invention
The purpose of this utility model provides a kind of above-mentioned shortcoming that overcomes, and is rational in infrastructure, and good buffer effect can improve rigidity, can bear the horizontal force of 450-500KN, guarantees that large tonnage crane operates steadily, the crane runway fixer of safety.
The purpose of this utility model is to realize like this, it is by base, be buckled in the last clamp on the base, be arranged on the adjustment key between base and the last clamp, and be positioned at flat gasket and spring washer on the clamp, pass the T type bolt of base, last clamp, flat gasket and spring washer successively, nut is formed, it is characterized in that clamp has two bolts hole on described, in the middle of last clamp, be provided with the bigger strengthening rib of rigidity, form
Structure, base are made " recessed ", and the middle part has the opening that is complementary with last clamp strengthening rib, has bolt hole on two plush coppers, bolt hole, flat gasket and the spring washer of T type screw bolt passes base, last clamp, and fastening by nut.
The utility model has the advantages that owing to adopted said structure, the center of gravity of clamp is reduced, rigidity improves, and has not only resisted the side force of crane effectively, transmits side force but also help clamp, guarantees that large tonnage crane is steady, safe operation.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the lateral plan of Fig. 1.
Accompanying drawing 3 is the cutaway view of clamp on the utility model.
Accompanying drawing 4 is the cutaway view of the utility model base.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to accompanying drawing 1, the utility model is by base 1, be buckled in the last clamp 2 on the base 1, be arranged on the adjustment key 3 between base 1 and the last clamp 2, and be positioned at flat gasket 7 and spring washer 6 on the clamp 2, pass the T type bolt 4 of base 1, last clamp 2, flat gasket 7 and spring washer 6 successively, nut 5 is formed, it is characterized in that clamp 2 has two bolts hole 8 on described, in the middle of last clamp 2, be provided with the bigger strengthening ribs of rigidity 9, form
Structure, the effect of its strengthening rib is the side force of resisting crane effectively, base 1 of the present utility model is made " recessed " type, the middle part has the opening 10 that is complementary with last clamp 2 strengthening ribs, have bolt hole 11 on two plush coppers, the size of 1 liang of plush copper of its base and two recesses on the last clamp 2 are complementary, its objective is that the strengthening rib that can make clamp snaps in the peristome of base easily, two plush coppers also just snap in two recesses of clamp 2, be provided with between base 1 and the last clamp 2 in addition and adjust key 3, base 1 both sides have bolt hole 10, T type bolt 4 passes base 1 successively, the bolt hole 8 of last clamp 2, flat gasket 7 and spring washer 6, and fastening by nut 5, whole like this fixer rigidity improves, can be more firmly fixing rail.The fixer of this structure can not only reach the crane brake system to the side force of crane, and can also bear bigger horizontal force, and maximum can be born the horizontal force of 500KN.Base of the present utility model in addition and last clamp all adopt 16Mn casting, and bolt adopts 8.8 grades, and each fixer has two bolt, even long-term use is shaken, also can not come off, and make and safer, reliable.
