Abstract
The utility model discloses a connecting piece between a main beam and a support frame of a crane. The connecting piece is characterized in that a circular convex block which is fixedly connected on a connecting seat of the support frame is arranged in a circular concave cover fixed on a connecting seat of the main beam; and a gap is left between the inner side wall of the circular concave cover and the outer side wall of the circular convex block corresponding to the inner side wall of the circular concave cover. The top part of the circular concave cover is fixedly connected with a stainless steel cushion plate. The gap t is equal to tgalpha.h, wherein alpha is a rotating angle formed between the connecting seat of the main beam and the connecting seat of the support frame, and h is the height of the inner side wall of the circular concave cover and the corresponding part of the outer side wall of the circular convex block. A groove at the top part of the circular convex block is provided with a rubber pad and a sealing steel plate in sequence from bottom to top. An antifriction plate is fixed on the sealing steel plate. Lubricating grease is arranged between the stainless steel cushion pad and the antifriction plate. Since the gap is left between the inner side wall of the circular concave cover and the outer side wall of the circular convex block corresponding to the inner side wall of the circular concave cover, and the antifriction plate and the rubber pad have buffering function, the connecting piece can effectively buffer the impact force of the main beam to the support frame.
Description
Technical field
The utility model relates to the attaching parts between the attaching parts on the hoisting crane, particularly crane girder and bracing frame.
Background technology
At present, need between crane girder that has and the bracing frame to adopt and flexibly connect, such as, the gauntry crane that shipbuilding is used is because of hoisting capacity, span with highly all increasing day by day, ship-building gantry crane is big because of span, what the connection structure between bracing frame and girder adopted generally speaking is that a side is rigidly connected, be that bracing frame and girder are fixed together, opposite side is for flexibly connecting, be that bracing frame and girder ball pivot link together, as shown in Figure 1, and ball pivot connects required material, heat treatment requirements is all than higher, make relatively difficulty, and can not effectively cushion the impulsive force of girder bracing frame.
Summary of the invention
The problem that the utility model solves provides a kind of girder that can effectively cushion to the impulsive force of bracing frame, crane girder of being convenient to process and the attaching parts between bracing frame.Task of the present utility model is finished like this, attaching parts between crane girder and bracing frame, it is characterized in that: be connected in round bump on the bracing frame Connection Block and be located at the circular recessed lid the inside that is fixed on the girder Connection Block, be provided with the gap between the lateral wall of the madial wall of circular recessed lid and the round bump relative with it.Circular recessed tops is fixed with the corrosion-resistant steel backing plate.Described clearance t=tg α h, wherein α is the corner that produces between girder Connection Block and bracing frame Connection Block, h is the madial wall of circular recessed lid and the height of the corresponding part of lateral wall of round bump.Be disposed with rubber pad, sealing steel plate in the groove at round bump top from down to up.Be fixed with the antifriction plate on the sealing steel plate.Be provided with grease between corrosion-resistant steel backing plate and the antifriction plate.Be provided with seal ring between the corresponding part in circular recessed lid lower surface with round bump.
Hoisting crane of the present utility model is installed in when work, because of the madial wall of the recessed lid of circle and and the lateral wall of its corresponding round bump between be provided with the gap, add the buffer action of antifriction plate, rubber pad, can effectively cushion the impulsive force of girder to bracing frame; This is simple in structure, brings a lot of convenience for the processing and the maintenance of material.
Description of drawings
Fig. 1 is the spherical hinge structure scheme drawing;
Fig. 2 is a structural representation of the present utility model.
Drawing explanation: 1, girder Connection Block; 2, circular recessed lid; 3, corrosion-resistant steel backing plate; 4, antifriction plate; 5, sealing steel plate; 6, rubber pad; 7, round bump; 8, bracing frame Connection Block; 9, seal ring.
The specific embodiment:
In conjunction with above accompanying drawing the utility model is described in further detail, being fixed on round bump 7 on the bracing frame Connection Block 8 is located at and is fixed on circular recessed lid 2 the insides on the girder Connection Block 1, be provided with the gap between the lateral wall of the madial wall of circular recessed lid 2 and the round bump 7 relative with it, this clearance t=tg α h, wherein α is the corner that produces between girder Connection Block and bracing frame Connection Block, and h is the madial wall of circular recessed lid and the height of the corresponding part of lateral wall of round bump; Circular recessed lid 2 tops are fixed with corrosion-resistant steel backing plate 3; Be placed with rubber pad 6, sealing steel plate 5 in the groove at round bump 7 tops from down to up successively; Be fixed with antifriction plate 4 on the sealing steel plate 5; Be provided with grease between corrosion-resistant steel backing plate 3 and the antifriction plate 4. be provided with seal ring 9. between the corresponding part in circular recessed lid lower surface with round bump
During installation, the girder Connection Block 1 and the girder of this usefulness utility model is fixed together, bracing frame Connection Block 8 is fixed together with bracing frame and gets final product.When girder produced structural stretch, corrosion-resistant steel backing plate 3 and antifriction plate 4 produced slippage, made 8 of girder Connection Block 1 and bracing frame Connection Blocks that slide relative take place, and discharged the horizontal direction power of girder to lower support frame; When main beam stress produced the perpendicular inside lock, rubber pad 6 partial compression made 8 of girder Connection Block 1 and bracing frame Connection Blocks produce certain corner, discharge the thrust of girder to bracing frame; Thereby effectively cushion the impulsive force of girder to bracing frame.
