Description

A cabin parking device Technical Field

[0001] This utility model relates to the field of ship engine room operation technology, and in particular to an engine room operation parking device. Background Technology

[0002] In the existing technology, many engine room cranes for ships do not have parking devices. Now, more and more ship owners are asking for the addition of parking devices to prevent the engine room cranes from becoming unstable when the ship encounters strong winds and waves, which could cause the cranes to collide with the hull structure. Summary of the Invention

[0003] The purpose of this utility model is to provide a cabin driving parking device, which adds a parking plate under the cabin driving guide rail, and the parking plate and the guide rail are stopped by a rack and pinion meshing.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A cabin crane parking device includes a track, rollers, and roller shafts. The track is arranged along the front-to-back direction, and the rollers and roller shafts are symmetrically arranged on the left and right sides of the track. The rollers are sleeved on the outside of the roller shafts, and the rollers rotate around the roller shafts and move back and forth along the track.

[0006] The lower end of the track is provided with a track rack, and the parking device also includes a parking plate. The upper end of the parking plate is provided with a positioning rack along the front-back direction. The positioning rack is limited to the center of the parking plate by the left and right side blocks. A lead screw is provided through the center of the parking plate vertically. The upper end of the lead screw and the lower end of the positioning rack cooperate. The lead screw drives the positioning rack to rise and fall. The positioning rack cooperates with the track rack to stop.

[0007] Furthermore, the parking platform is symmetrically provided with support blocks at both ends, and the support blocks support the traveling frame outside the roller axle.

[0008] Furthermore, a wing nut is fixedly provided at the center of the lower end of the parking plate, and the lead screw is rotatably connected to the wing nut.

[0009] This utility model adds a parking mechanism to the traditional engine room crane guide rail. The parking plate is equipped with a screw-driven liftable positioning rack. When the positioning rack is raised to the highest point, it engages with the rack under the guide rail to restrict the movement of the crane. When the positioning rack is lowered, the positioning rack and the rack under the guide rail do not contact each other, and the crane can move freely. This utility model has a simple and reliable structure and is easy to implement in engine room cranes. Attached Figure Description

[0016] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] This embodiment discloses a cabin driving and parking device, as shown in Figure 1, which includes a track 1, rollers 2 and roller shafts 3. The track 1 is arranged in the front-to-back direction. The rollers 2 and roller shafts 3 are symmetrically arranged on the left and right sides of the track 1. The rollers 2 are sleeved on the outside of the roller shafts 3. The rollers 2 rotate around the roller shafts 3 and move back and forth along the track 1. The lower end of the track 1 is provided with a track rack 4.

[0018] As shown in Figure 1, the parking device also includes a parking plate 5. The upper end of the parking plate 5 is provided with a positioning rack 6 along the front-back direction. A pair of stops 7 are symmetrically provided in the middle of the parking plate 5. The positioning rack 6 is limited in the center of the parking plate 5 by the stops 7 on the left and right sides. The height of the stops 7 is higher than the initial low point height of the positioning rack 6. The stops 7 will only protrude from the upper end of the stops 7 when the positioning rack 6 is lifted.

[0019] A lead screw 8 is installed vertically through the center of the parking plate 5. The upper end of the lead screw 8 is engaged with the lower end of the positioning rack 6. The lead screw 8 drives the positioning rack 6 to rise and fall. A wing nut 10 is fixedly installed at the center of the lower end of the parking plate 5. The lead screw 8 and the wing nut 10 are engaged and rotated together.

[0020] In this embodiment, as shown in Figures 1 and 2, the lead screw 8 is turned to raise the positioning rack 6 to the highest point, so that the track rack 4 at the lower end of the track 1 meshes with the positioning rack 6 for fixing and stops the trolley, preventing it from moving forward, backward or left and right, thus achieving a fixing effect. The lead screw 8 is then turned back to lower the positioning rack 6 to the lowest point, allowing the trolley to move freely again.

[0021] As shown in Figures 1 and 3, the parking platform 5 is symmetrically provided with support blocks 9 at both ends. The support blocks 9 support the traveling frame 11 on the outside of the roller shaft 3. The support at both ends of the support blocks 9 can help stabilize the traveling structure of the cabin car.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
