Description

Technical Field

[0001] This invention relates to pulley supports for quay cranes and yard cranes, and more specifically, to a pulley support. Background Technology

[0002] As the basic structure of a pulley system, the pulley support primarily bears the tensile force in the direction of the wire rope, but it also needs to withstand the lateral force caused by the deflection angle of the wire rope. The pulley support mainly consists of a main support plate and a sheathing plate. The main support plate has a strong capacity to bear the tensile force in the direction of the wire rope, but its capacity to bear lateral forces is weak. Therefore, a sheathing plate is needed to improve its lateral load-bearing capacity.

[0003] The existing pulley support adopts a form where the entire support plate is wrapped with edges, as shown in the attached figure. Figure 1 As shown, the outer sides of the two main support plates 1 are completely covered by the cover plate 2. This design makes the pulley support very strong in bearing lateral loads, but there is too much design redundancy. In actual production, the cover plate 2 is bent by heat treatment. Although this method can meet the design requirements, the construction is relatively complicated, and heat treatment poses a great safety hazard. Sometimes, the temperature is too high and overheating occurs, which has a certain negative impact on product quality. Summary of the Invention

[0004] In view of the above-mentioned defects in the existing technology, the purpose of this invention is to provide a pulley support that reduces the manufacturing difficulty and improves production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pulley support includes a support main plate disposed on the outer side of the box structure, and a cover plate covering the outer side of the support main plate.

[0007] The packaging plate includes a first packaging plate and a second packaging plate;

[0008] The first cover plate is disposed on the upper surface of the main support plate;

[0009] The second cover plate is disposed on the lower surface of the main support plate and is connected to the outer side of the box structure;

[0010] Both the first and second packaging plates are H-shaped plates.

[0011] Preferably, a weight plate is provided at the position where the pulley is mounted on the main support plate.

[0012] Preferably, the opening widths of the first and second packing plates toward the weight plate are adapted to the width of the pulley.

[0013] Preferably, the second package plate has a foot at the end away from the weighing plate;

[0014] The base is connected to the outer side of the box structure.

[0015] Preferably, the connection between the support main board and the housing structure is provided with a soldering hole.

[0016] The pulley support provided by this invention replaces the existing plate with a partial edge-wrapping design. This method allows for direct welding after CNC cutting, eliminating the need for heat treatment bending, reducing manufacturing difficulty, improving production efficiency, and providing a more reasonable design that saves a lot of resources, in line with the concept of green development.

[0024] To better understand the above-mentioned technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Combination Figures 3 to 7 As shown, the pulley support provided by the present invention includes two support plates 4 disposed on the outer side of the housing structure 3, and a cover plate covering the outer side of the two support plates 4. The above is the prior art and will not be described again here. Unlike the prior art, the cover plate in the present invention includes a first cover plate 5 and a second cover plate 6.

[0026] The first cover plate 5 is welded to the upper surface of the support main plate 4.

[0027] The second cover plate 6 is welded to the lower surface of the support main plate 5 and is also welded to the outer side of the box structure 3.

[0028] Both the first cover plate 5 and the second cover plate 6 are set as H-shaped plates, which are welded together with the main support plate 4 and the box structure 3 to increase the stability of the main support plate 4.

[0029] A heavy-duty plate 7 is welded onto the pulley position on the main support plate 5.

[0030] The width of the openings 8 of the first packing plate 5 and the second packing plate 6 facing the heavy-duty plate 7 is matched with the width of the pulley, which is suitable for the rolling of the pulley.

[0031] The second packing plate 6 has a foot 9 on the end away from the weighing plate for welding to the outer side of the box structure 3.

[0032] Due to the actual welding problems of the first cover plate 5 and the second cover plate 6, since the angle between the first cover plate 5 and the box structure 3 is small, which is not conducive to welding operations, only the base plate 9 is set on the second cover plate 6 to be welded to the box structure 3.

[0033] A weld hole 10 is provided at the connection between the support main board 4 and the box structure 3 to reduce the adverse effects of weld intersection on the box structure 3.

[0034] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any variations or modifications to the above embodiments that are within the spirit and essence of the present invention will fall within the scope of the claims of the present invention.
