Description

Technical Field

[0001] The invention relates to a swing bridge which is suitable for swing bridges of indoor and outdoor amusement projects. Background Art

[0002] At present, swing bridges are a very popular amusement product. They use fasteners on both sides to fix steel wire ropes or chains, and lay the bridge deck on the chains or steel wire ropes. Because the fasteners on both sides are non-rigidly connected to the fixed seats, the bridge deck will swing. This swing is used to increase the swing amplitude of the bridge deck when tourists swing back and forth on the bridge deck to achieve the purpose of amusement. However, during the swinging process, there is relative friction between the fasteners and the fixed seats, which causes great wear on the fasteners. The greater the swing amplitude of the bridge deck, the greater the wear on the fasteners, which affects the safety and service life of the swing bridge. Summary of the invention

[0003] The present invention aims at the disadvantages of the prior art and can reduce the wear of the swing bridge fasteners, thereby improving the safety of the swing bridge and the service life of the low-wear swing bridge.

[0004] The technical aspects of the present invention include steel wire ropes, fasteners, and fixed frames. The steel wire ropes have two parallel lines, which are respectively installed on the fixed frames through fasteners, and a bridge plate is laid on the two parallel steel wire ropes. The feature of the present invention is that the fastener adopts a composite hinge, which is composed of a cylindrical bearing and a connecting cylinder. Both ends of the inner ring of the cylindrical bearing are fixedly installed on the fixed frame, and the outer ring and the connecting cylinder are fixedly connected by a connecting plate. The center lines of the cylindrical bearing and the connecting cylinder are parallel to each other. A connecting buckle is fixedly installed at the center of one end face of the connecting cylinder, and the other end of the connecting buckle is connected to the steel wire rope. The two cylindrical bearings are horizontally installed on the fixed frame, and the centers of the two connecting cylinders are on the same horizontal plane. The distance between the centers of the two cylindrical bearings is equal to the distance between the centers of the two connecting cylinders.

[0005] Preferably, a positioning plate is installed between the centers of the other end surfaces of the two connected cylinders.

[0006] Preferably, the connecting cylinder adopts a second cylindrical bearing, whose outer ring is fixedly connected to one end of the connecting plate, and the connecting buckle is fixedly installed at the center of one end surface of the inner ring of the second cylindrical bearing.

[0007] Preferably, the inner ring of the second cylindrical bearing is connected to the connecting buckle by a flange, and the connecting buckle is welded at the center of the flange end surface.

[0008] Preferably, the cylindrical bearing is composed of deep groove ball bearings and tapered roller bearings installed at both ends between the outer ring and the inner ring. The deep groove ball bearing is installed between the radial outer step of the inner ring and the radial inner step of the outer ring on the side close to the connecting buckle, and the tapered roller bearing is installed between the inner step of the outer ring and the pressure plate on the inner cavity on the other side.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: the fastener adopts a composite hinge structure composed of a cylindrical bearing and a connecting cylinder, and the movable part is the rolling friction of the bearing, which reduces the wear degree of the fastener and improves the service life and safety of the product.

DETAILED DESCRIPTION

[0014] like Figure 1 The low-wear swing bridge shown in the figure comprises a steel wire rope 4, a fastener, and a fixing frame 5. The steel wire rope 4 has two parallel wire ropes, which are respectively installed on the fixing frame 5 through fasteners, and a bridge deck 1 is laid on the two parallel steel wire ropes 4; its characteristic is that the fastener adopts a composite hinge, which is composed of a cylindrical bearing 3 and a connecting cylinder 2. Both ends of the inner ring 6 of the cylindrical bearing 3 are fixedly installed on the fixing frame 5, and the outer ring 7 is fixedly connected to the outer cylindrical surface of the connecting cylinder 2 through a connecting plate 8. The center lines of the cylindrical bearing 3 and the connecting cylinder 2 are parallel to each other, and a connecting buckle 9 is fixedly installed at the center of one end face of the connecting cylinder 2. The other end of the connecting buckle 9 is connected to the steel wire rope 4. The two cylindrical bearings 3 are installed on the fixing frame 5 in a horizontal direction, and the centers of the two connecting cylinders 2 are on the same horizontal plane. The distance between the centers of the two cylindrical bearings 3 is equal to the distance between the centers of the two connecting cylinders 2, as shown in FIG. Figure 2 When tourists swing back and forth on the bridge deck, the steel wire ropes 4 on both sides of the bridge deck drive the connecting buckle 9, the connecting cylinder 2, the connecting plate 8, and the outer ring 7 of the cylindrical bearing 3 to swing left and right relative to the fixing frame 5. The swinging friction force is the rolling friction between the outer ring 7 and the inner ring 6 of the cylindrical bearing 3, which reduces the wear of the fasteners and improves the safety and service life of the fasteners.

[0015] A positioning plate 10 is installed between the centers of the other end faces of the two connecting cylinders 2. The two ends of the positioning plate 10 are respectively hinged to one of the connecting cylinders 2 to limit the distance between the two connecting cylinders 2 during the swinging process, ensure that the steel wire ropes 4 on both sides of the bridge deck swing synchronously, and reduce the lateral force of the bridge deck 1 during swinging.

[0016] The connecting cylinder 2 adopts a second cylindrical bearing, whose outer ring 11 is fixedly connected to one end of the connecting plate 8, and the center of the inner ring 12 is fixedly connected to the connecting buckle 9. During the swinging process, the connecting cylinder 2 rotates while revolving with the inner ring 6 of the cylindrical bearing 3, thereby increasing the swing amplitude of the bridge deck 1.

[0017] The inner ring 12 of the second cylindrical bearing is connected to the connecting buckle 9 by a flange 13, and the connecting buckle 9 is welded to the center of the end face of the flange 13 to avoid friction caused by the relative rotation between the two. The connecting buckle 9 made of wear-resistant material can also be connected in the center hole of the flange 13.

[0018] The cylindrical bearing 3 is composed of a deep groove ball bearing 14 and a tapered roller bearing 15 installed at both ends between the outer ring 7 and the inner ring 6. The deep groove ball bearing 14 is installed between the radial outer step of the inner ring 6 and the radial inner step of the outer ring 7 on the side close to the connecting buckle 9, and the tapered roller bearing 15 is installed between the inner step of the outer ring 7 and the pressure plate 16 on the inner ring 6 on the other side, so as to improve the oblique force strength of the cylindrical bearing 3. The second cylindrical bearing adopts the same structure as the cylindrical bearing 3, such as Figure 3 shown.

[0019] The inner ring 6 of the cylindrical bearing 3 is welded at both ends to the mounting plate 17, and the mounting plate 17 is fixedly mounted on the mounting frame 5. Figure 1 , Figure 2 The connecting buckle 9 is made of a stainless steel nut, which is connected to one end of the basket screw 19 through an O-shaped buckle 18, and the other end of the basket screw 19 is connected to the wire rope 4. Figure 3 The inner ring 6 is of cylindrical structure, and the outer ring 7 is of high-strength alloy steel material to ensure the strength of the cylindrical bearing 3.
