Description

TECHNICAL FIELD

[0001] The present application relates to a kind of special tool for segment upper transfer and bracket for segment transfer. BACKGROUND

[0002] In the process of shipbuilding, etc., bracket is used for segment upper transfer position, and a large number of brackets are barge transported and stored every day. The barge transport bracket is lifted by a forklift, and then the bracket is lifted. In order to ensure that the bracket does not slip, the center of gravity of the bracket and the center of the fork must be aligned. This process must be constantly corrected, which is time-consuming. There is little research on this aspect in the prior art. In the April 2021 issue of Ship Ocean Engineering, Vol. 50, No. 2, Liu Yinghan published "Technological improvement of groove type bulkhead segment manufacturing precision control and storage barge deformation". It analyzes the process influencing factors of segment manufacturing process, off-site transfer and storage process, and summarizes the new process to solve the problems of groove type bulkhead segment manufacturing and deformation during transfer. Compared with the traditional process, the new process can significantly improve the manufacturing precision of the groove type bulkhead segment and the deformation problem during transfer. However, it does not solve the problem of water accumulation in the groove type bulkhead segment during transfer.

[0003] In addition, the bracket should consider the load bearing of the ground and the transverse and longitudinal stress conditions after the segment is placed, as well as the safety factors of lifting and transportation, so as to reasonably select materials and ensure safety. Strengthen the safety management of the bracket during shipbuilding and offshore construction to prevent segment collapse accidents. In addition, there is no solution to the problem of water accumulation in the groove type bulkhead segment during transfer from the perspective of the bracket. SUMMARY

[0004] The purpose of the present application is to overcome the defects in the prior art and provide a special tool for segment upper transfer. The tool center is marked with a center line, which can be quickly aligned with the center line of the bracket. The tool is easy to use and reduces safety hazards.

[0005] To achieve the above purpose, the technical solution of the present application is to design a special tool for segment upper transfer, which includes a pair of groove-shaped feet, a groove-shaped outer plate fixedly connected to the feet, and a groove-shaped outer plate whose shape is adapted to the shape of the barge transport bracket. The length of the foot exceeds the groove width of the groove-shaped outer plate, and the part of the foot exceeding the outer plate is fixedly connected with an elbow plate, and the elbow plate is also fixedly connected with the outer plate. The outer wall of the groove-shaped outer plate is coated with a mark layer indicating the center position. The tool center is marked with a center line, which can be quickly aligned with the center line of the bracket. The tool is easy to use and reduces safety hazards.

[0006] Further technical solutions are that the bottom foot is fixedly connected with a bottom sealing plate, and the bottom sealing plate and the bottom foot form a rectangular ring after being connected; the outer plate is integrally provided with a curved section extending outward at both ends; and the elbow plate is provided with four pieces, and the plate surface of the elbow plate is in the shape of a triangular plate. The bottom sealing plate and the bottom foot form a rectangular ring after being connected, so that the fork of the forklift is inserted to facilitate the transfer of the bracket.

[0007] Further technical solutions are that the groove-shaped bottom foot is provided with a groove away from the outer plate; the upper wall of the bottom foot is provided with a through hole, and the corresponding position of the groove bottom wall of the groove-shaped outer plate is also provided with a through hole, the two through holes are connected to form a through hole, and a rubber column with a small middle and large ends is arranged on the through hole. After the fork of the forklift is inserted into the groove-shaped bottom foot (or the rectangular ring) of the tooling, the fork of the forklift moves upward while extruding the rubber column, so that not only the groove-shaped outer plate of the tooling supports the bracket and drives the bracket to move upward together, but also the friction between the bracket and the outer plate of the tooling is enhanced during the transfer of the bracket, so that the transfer process is very stable.

[0008] Further technical solutions are that the through holes on the upper wall of the bottom foot and the through holes on the outer plate are all inclined and have consistent inclination directions.

[0009] The through holes on the upper wall of the bottom foot and the through holes on the outer plate are provided with a plurality of pairs, each pair of through holes forms a through hole, and the inclination directions of different through holes are different. By arranging a plurality of rubber columns with different inclination directions, a plurality of triangularly arranged rubber columns can be formed, the stability during the transfer process is enhanced, the relative sliding between the bracket and the tooling is avoided, and the safety is improved.

[0010] Further technical solutions are that a drainage pipeline is arranged on the outer plate and the bottom foot, and two pipeline openings of the drainage pipeline are located on the bottom wall of the outer plate and the upper wall of the bottom foot, respectively.

[0011] A drainage hole is arranged on the bottom sealing plate. One solution is to arrange a drainage hole on the bottom sealing plate; additionally, a reinforcing rib can be welded in the bottom sealing plate and the bottom foot, and a drainage channel is arranged in the reinforcing rib, the drainage channel is connected with the drainage pipeline arranged on the outer plate and the bottom foot, so that the discharged water can not flow through the surface of the bottom foot or the bottom sealing plate, the rust problem after long-term use is avoided, the water flow is limited in the drainage channel and the drainage pipeline, and an anticorrosive layer can be coated on the inner wall of the drainage channel or the drainage pipeline to enhance the service life of the invention. Another solution is to arrange a drainage hole only on the bottom wall of the outer plate (to avoid the area of the fork of the forklift), and a water discharge hole is arranged at the corresponding position of the bottom plate of the bracket cross beam to facilitate the discharge of water accumulated in the groove-shaped bulkhead segmented groove-shaped plate. In this case, the position of the drainage hole corresponds to the position of the drainage channel (a reinforcing rib is welded in the cross beam, and a drainage channel is arranged in the reinforcing rib, and two channel openings of the drainage channel are located on the upper plate surface of the cross beam and the lower plate surface of the cross beam, respectively).

[0012] The application also provides a technical solution of a bracket for transferring segments, which comprises a bracket crossbeam and supporting legs fixedly connected to the two ends below the crossbeam.

[0013] The channel opening on the lower plate surface of the drainage channel corresponds to the position of the pipe opening on the bottom wall of the outer plate of the drainage pipe of the special tool for transferring the segment upper frame.

[0014] Further technical solutions are that the bracket is used for transferring a groove type bulkhead segment, and a drainage hole is formed on the bottom plate of the groove type bulkhead segment, and a rubber ring with a cross-section in the shape of an I-beam is sleeved on the hole side wall of the drainage hole.

[0015] Further technical solutions are that a middle small and two end large rubber plug is provided in combination with the drainage channel, the length of the rubber plug is greater than the size of the drainage channel, the shape of one end of the rubber plug is matched with the drainage hole on the bottom plate of the groove type bulkhead segment, the shape of the other end of the rubber plug is matched with the drainage channel, and the rubber plug is arranged to be beyond the lower channel opening of the drainage channel.

[0016] The application has the advantages and beneficial effects of rapid alignment.

[0017] The bottom sealing plate is connected with the supporting leg to form a rectangular ring for the insertion of the fork of a forklift to facilitate the transfer of the bracket.

[0018] After the forklift fork is inserted into the channel steel-shaped foot (or rectangular ring) of the tooling, the forklift fork is moved upward while extruding the rubber columns, so that not only the channel steel-shaped outer plate of the tooling supports the bracket and drives the bracket to move upward together, but also the friction between the bracket and the outer plate of the tooling is enhanced during the transfer of the bracket due to the extrusion of the rubber columns, so that the transfer process is very stable.

[0019] The plurality of rubber columns are arranged to have different inclined directions, so that the plurality of triangularly arranged rubber columns are formed, the stability of the transfer process is further enhanced, the relative sliding between the bracket and the tooling is avoided, and the safety is improved.

[0020] The drainage pipeline on the tooling is arranged at a position consistent with the drainage passage on the bracket (after the tooling and the bracket are centered), so that the accumulated water in the segmented channel-shaped plate on the bracket can be discharged, the accumulated water during the transfer of the bracket is solved, and the safety risk of the transfer of the bracket is reduced. The drainage passage is arranged in the reinforced rib plate, so that the problem of water flowing through the inner wall of the beam caused by directly opening a drainage hole on the beam face plate and the bottom plate is avoided.

[0021] The drainage hole is arranged on the bottom plate of the channel-shaped bulkhead segment, so that the drainage hole is arranged before assembly, and the accumulated water in the rainy season can be effectively avoided during the transfer of the bracket (when the bracket carries the segment during the transfer) or the segment storage and transfer, so that the accumulated water can be discharged, the deformation of the channel caused by the accumulated water is reduced, and the safety problem of the transfer of the bracket or the channel-shaped bulkhead caused by the accumulated water is avoided.

[0022] The rubber plug in the dumbbell shape is arranged, and the length of the rubber plug exceeds the length of the drainage passage, so that the rubber plug can be pushed upward when the bracket is transferred in the non-rainy season, the drainage hole on the segment is prevented from being blocked by impurities, and the rubber plug is pulled out to facilitate the discharge of the accumulated water in the rainy season.

DETAILED DESCRIPTION

[0034] The specific embodiments of the present application are further described below in conjunction with the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present application, and cannot be used to limit the protection scope of the present application.

[0035] As Figures 1 to 10 shown (for the convenience of illustration, Figure 4The present application is a special tool for segment upper frame transfer, which comprises two channel steel-like feet 1 arranged in pairs, the channel steel-like outer plates 2 fixedly connected to the feet 1, the shape of the channel steel-like outer plates 2 being matched with the shape of the transfer bracket, the length of the feet 1 exceeding the slot width of the channel steel-like outer plates 2, the part of the feet 1 exceeding the outer plates 2 being fixedly connected with the elbow plates 3, the elbow plates 3 being fixedly connected with the outer plates 2, and the outer walls of the channel steel-like outer plates 2 being coated with the identification layer 4 indicating the center position. The feet 1 are fixedly connected with the bottom sealing plates 5, and the bottom sealing plates 5 form a rectangular ring after being connected with the feet 1. The two ends of the outer plates 2 are integrally provided with the outwardly extending curved sections 6. The elbow plates 3 are provided in total four, and the plate surface of the elbow plates 3 is in the shape of a triangular plate. The slot of the channel steel-like feet 1 is arranged away from the outer plates 2. The upper wall of the feet 1 is provided with a through hole, and the corresponding position of the bottom wall of the channel steel-like outer plates 2 is also provided with a through hole, the two through holes being connected to form a through hole, and the through hole being provided with the rubber column 7 with small middle and large two ends. The through holes on the upper wall of the feet 1 and the through holes on the outer plates 2 are all arranged in an inclined manner and have consistent inclined directions. The through holes are provided in pairs, each pair of through holes forms a through hole, and the inclined directions of different through holes are different.

[0036] The bracket for segment transfer comprises a bracket cross beam 8 and the supporting feet 9 fixedly connected to the two ends below the cross beam 8. The cross beam 8 is in the shape of a rectangular shell and is welded by six plates. The cross beam 8 is welded with the reinforcing rib plate 10. The reinforcing rib plate 10 is provided with the drainage channel 11. The two channel openings of the drainage channel 11 are respectively located on the upper plate surface of the cross beam 8 and the lower plate surface of the cross beam 8. Only the drainage holes 12 are arranged on the bottom wall of the outer plates 2 on the tool, and the positions of the drainage holes 12 correspond to the positions of the drainage channel 11. The bracket is used for transferring the slot type bulkhead segment 13. The bottom plate of the slot type bulkhead segment 13 is provided with the drainage holes 12. The hole side wall of the drainage holes 12 is sleeved with the rubber ring 14 in the shape of an I-beam. The rubber plug 15 with small middle and large two ends is matched with the drainage channel 11. The length of the rubber plug 15 is greater than the size of the drainage channel 11. The shape of one end of the rubber plug 15 is matched with the shape of the drainage holes 12 on the bottom plate of the slot type bulkhead segment 13. The shape of the other end of the rubber plug 15 is matched with the shape of the drainage channel 11. The rubber plug 15 is arranged at the lower end of the drainage channel 11 and exceeds the lower channel opening of the drainage channel 11. The top end of the bracket is provided with the positioning protrusion 17 matched with the groove formed between the reinforcing ribs 16 on the segment (the positioning protrusion 17 plays a role in stabilizing the transfer segment). The surface of the positioning protrusion 17 is coated with the rubber layer for enhancing the friction force (this way is for the scheme when the segment is unstable during the transfer. The segment needs to be turned over before the transfer, and then placed on the bracket after the turning over, as shown in Figure 10 The top plate of the cross beam 8 is grooved, and the counterweight 18 is inserted into the groove.

[0037] The working principle is as follows:

[0038] Because the rubber column is dumbbell-shaped, the middle size is small, and the two ends are large, so after the forklift fork is inserted into the tool bottom foot, the rubber column moves upward (that is, moves towards the direction close to the bracket), and after the tool's groove-shaped bottom plate contacts the bracket, the bracket exerts pressure on the rubber column during the upward movement of the fork, and because multiple rubber columns are arranged and have different inclined directions, multiple triangularly arranged rubber columns are formed, which can strengthen the stability during the transfer process, avoid the relative sliding of the bracket and the tool, and improve the safety.

[0039] Drainage holes are formed in the bottom plate of the groove-shaped bulkhead section, which facilitates the drainage of water during the transfer of the bracket, and the hole side wall of the drainage hole is sleeved with a rubber ring with a H-shaped cross section (after being transferred to the assembly area, the rubber ring is removed during assembly, and a round steel plate is welded again to plug the drainage hole);

[0040] The top end of the bracket is provided with a positioning protrusion matched with the groove formed between the rib plate on the section (which plays a role in stabilizing the transfer of the section), and a rubber layer for enhancing friction is arranged on the surface of the positioning protrusion;

[0041] The top plate of the cross beam is slotted, and a counterweight is inserted into the slot, so that when the section size is large enough to cover the entire bracket, the counterweight is removed to reduce the weight of the bracket, and when the section size is small and only covers part of the bracket, part of the counterweight is left to avoid the center of gravity of the bracket not being in the middle position. This arrangement ensures that the center of gravity of the entire section is as close to the middle position of the bracket as possible.

[0042] The above is only a preferred embodiment of the present application, and it should be noted that for ordinary skilled persons in the technical field, several improvements and refinements can be made without departing from the technical principles of the present application, and these improvements and refinements should also be considered within the protection scope of the present application.
