Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically, it is a compact ship piping vehicle. Background Technology

[0002] A ship piping trolley is a specialized piece of equipment used for the installation and maintenance of ship piping systems. It is typically used to help workers move various accessories such as flanges and valves in ship piping, making it easier for workers to reach different parts of the pipeline.

[0003] Tubing trolleys are typically located within the tubing. For large transport vessels, the tubing is situated within the double bottom, providing ample space for the trolleys, thus placing fewer design requirements on them. However, for smaller vessels, the double bottom / tunnel space is limited. Consequently, conventional tubing trolley and structural designs are insufficient for trolley placement.

[0004] Referring to the patent with authorization announcement number CN204223697U, a pipe trolley system typically consists of a track support structure, tracks, and a pipe trolley. The track support structure is arranged on the ship's structure to support the tracks. For small ships, the double bottom / pipeline height is relatively small, and usually only manholes for personnel passage can be opened in the transverse structure of the double bottom, making it impossible to install a pipe trolley. In this case, the maintenance and replacement of ship piping valves can only be done by manual handling, which is extremely inconvenient.

[0005] Therefore, the existing technology has the following drawbacks:

[0006] 1. Ordinary tunnel carts and their layouts occupy a large amount of space and are not suitable for small spaces;

[0007] 2. Small vessels can only have manholes, and it is very inconvenient for personnel to frequently cross the transverse structure when moving parts in the double bottom / tunnel.

[0008] 3. The structure of a typical manhole cannot meet the layout requirements of a tunnel trolley. Utility Model Content

[0009] The purpose of this invention is to provide a compact marine pipework vehicle layout structure to solve the problems existing in the prior art.

[0010] The purpose of this utility model is achieved as follows: a compact marine pipework arrangement structure, comprising:

[0011] A horizontally extending track that passes through several through holes in the tunnel structure and is fixedly connected to the bottom edge of the through holes;

[0012] The trolley body moves on the track and passes through the through hole. The trolley body includes a frame and several rollers that are rotatably connected to the frame. The rollers roll in cooperation with the track. The frame is generally a plate structure. The middle part of the frame is recessed and serves as the chassis part, which is close to the upper surface of the track.

[0013] Furthermore, the track is a strip plate extending along the moving direction of the trolley body, and there are two tracks distributed left and right.

[0014] Furthermore, the track has an obtuse-angled V-shaped cross-section, and from a cross-sectional perspective, the track is divided into a flat plate section and an inclined plate section, with the flat plate section cooperating with the roller.

[0015] Furthermore, the flat plate portion and the inclined plate portion are fixedly connected to and fit into the bottom edge of the through hole.

[0016] Furthermore, the rollers of the trolley body are divided into two groups distributed on the left and right, and the two groups of rollers respectively roll in cooperation with the two tracks.

[0017] Furthermore, both the front and rear portions of the frame are provided with roller mounting seats for mounting rollers.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. The middle part of the frame is recessed and serves as the chassis, close to the upper surface of the rail. The chassis of the tube trolley is lowered as much as possible and brought close to the bottom of the through hole to obtain a larger vertical space.

[0020] 2. It enables the arrangement of trolleys within narrow double-bottomed / pipe tunnels, facilitating the maintenance and transportation of piping valves within the double-bottomed / pipe tunnel. Attached Figure Description

[0025] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1-3 As shown, a compact marine pipework arrangement structure is proposed, including:

[0027] The horizontally extending track 2 passes through several through holes 3a of the tube structure 3 and is fixedly connected to the bottom edge of the through holes 3a.

[0028] The trolley body 1 moves on track 2 and passes through through hole 3a. The trolley body 1 includes a frame 102 and several rollers 101 rotatably connected to the frame 102. The rollers 101 roll in cooperation with the track 2. The frame 102 is generally plate-shaped. The front and rear parts of the frame 102 are both provided with roller mounting seats 103 for mounting the rollers 101. The middle part of the frame 102 is recessed and serves as the chassis, close to the upper surface of the track 2. The chassis of the trolley frame 102 is lowered as much as possible, close to the bottom of the through hole 3a (to reduce the risk of damage). Figure 3 The h value in the text is used to obtain a larger vertical space, and the trolley can be extended in length as needed to meet usage requirements.

[0029] The track 2 is a strip plate (preferably flat steel or other profile) extending along the moving direction of the trolley body 1. There are two tracks 2, distributed left and right, located at the bottom corners of the through hole 3a and welded to each other. Correspondingly, a reinforcing plate is also welded to the upper part of the through hole 3a.

[0030] In this embodiment, the area with the least stress on the transverse structure is selected, and the largest possible opening (through hole 3a) is achieved while meeting the requirements of strength and space. The form of the transverse structure channel opening, the longitudinal skeleton through hole and the patch plate of the double bottom / pipe are changed, and the thickness of the transverse structure plate at the opening is increased.

[0031] In a preferred embodiment, the cross-section of the track 2 is an obtuse-angled V-shape. From the perspective of the cross-section, the track 2 is divided into a flat plate portion 2a and an inclined plate portion 2b. The flat plate portion 2a cooperates with the rollers 101, that is, the two rows of rollers 101 roll on the flat plate portions 2a of the two tracks 2 respectively.

[0032] In a preferred embodiment, the flat plate portion 2a and the inclined plate portion 2b are fixedly connected to and fit into the bottom edge of the through hole 3a.

[0033] In a preferred embodiment, the rollers 101 of the trolley body 1 are divided into two groups distributed on the left and right, and the two groups of rollers 101 respectively roll in cooperation with the two tracks 2.

[0034] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
