Description

Technical Field

[0001] This invention relates to the field of underwater engineering construction technology, and in particular to a cable connection device and construction method for anchoring caissons in water. Background Technology

[0002] In deep water conditions, caissons used as bridge foundations are generally made of steel. Due to their huge size, they usually need to be processed and assembled in a factory to form a unified whole before being transported to the bridge site by floating. Then, under the fixed constraint of the anchoring system, they are filled with water and sunk to achieve precise landing.

[0003] During the installation of the mooring system, the caisson's position in the water changes from being stabilized by tugboats to being stabilized by the mooring system. The stability of the caisson is insufficient during the transition of the restraint system, and it bears higher risks under the action of wind, waves and currents. Therefore, the transition of the restraint system should be completed as quickly as possible to improve the safety of construction.

[0004] However, during actual construction, the anchor cables and winches need to be connected on the floating caisson platform. At this time, it is impossible to set up flexible lifting and installation equipment on the caisson, which makes the installation process of the mooring system too complicated. It is impossible to move large components on site by manual labor. Due to space constraints, mechanical equipment is difficult to use on site. The installation time is too long, and the mooring construction cannot be completed. The caisson will have to float on the water continuously. In the marine environment, with typhoons coming at any time, the risks will be difficult to control. Summary of the Invention

[0005] Based on this, the present invention provides a cable connection device and construction method for anchoring construction of caissons in water, which realizes the rapid connection of anchor cables and winches, shortens the installation time of the anchoring system, enables rapid anchoring construction of caissons, saves construction time, and reduces construction risks.

[0006] To achieve the above objectives, in a first aspect, the present invention provides a cable connection device for anchoring construction of a caisson in water, comprising a slide rail, a first conversion connection unit, a second conversion connection unit, and a hand-operated dragging unit. The slide rail is fixedly installed on the top platform of the caisson. The first conversion connection unit is detachably slidably mounted on the first end of the slide rail, with its rear end connected to a positioning anchor via an anchor cable and its front end having a convex connection portion. The second conversion connection unit is detachably slidably mounted on the second end of the slide rail, with its rear end connected to a jack via a steel strand and its front end having a concave connection portion adapted to the convex connection portion. The hand-operated dragging unit is drivenly connected to the first conversion connection unit and / or the second conversion connection unit, configured to drive the convex connection portion of the first conversion connection unit and the concave connection portion of the second conversion connection unit to engage with each other, and is driven by a pin passing through the pin holes of the convex and concave connection portions.

[0007] Furthermore, the first conversion connection unit includes a first adjusting seat and a closed cable section. The first adjusting seat is slidably mounted on the slide rail. The closed cable section is supported by the first adjusting seat. The anchor cable is connected to the rear end of the closed cable section. The convex connecting part is located at the front end of the closed cable section. The split structure of the first conversion connection unit facilitates the connection of the closed cable section and the anchor cable on site. It also facilitates placement on the first adjusting seat after connection and further movement back and forth on the slide rail.

[0008] Furthermore, the bottom of the first adjusting seat is supported on the slide rail by a first sliding roller, which includes a plurality of rollers and is spaced apart along the length of the slide rail.

[0009] Furthermore, the front ends of the closed cable section are configured as flat structures on both sides. The first adjustment seat is provided with adjustment bolts that are tightened to the flat parts on both sides of the closed cable section. The plane of the flat part of the closed cable section is perpendicular to the horizontal plane by the adjustment of the adjustment bolts. The circumferential angle of the large-volume and heavy closed cable section can be adjusted by simply rotating the adjustment bolts, which facilitates the angle adjustment of the large-volume closed cable section and creates conditions for subsequent connection.

[0010] Furthermore, the first adjusting seat is provided with multiple semi-circular slots spaced apart along the slide direction. The conical head of the closed cable joint is adapted to the shape of the semi-circular slots at the front end to adjust the axial direction of the closed cable joint to be consistent with the axial direction of the slide, thereby adjusting the planar angle.

[0011] Furthermore, the second conversion connection unit includes a second adjusting seat and an open cable joint. The second adjusting seat is slidably mounted on the slide rail. The open cable joint is supported by the second adjusting seat. The twisted rope is connected to the rear end of the open cable joint. The concave connecting part is located at the front end of the open cable joint. The split structure of the second conversion connection unit facilitates the connection of the open cable joint and the twisted rope on site. It also facilitates placement on the second adjusting seat after connection and further movement back and forth on the slide rail.

[0012] Furthermore, the second adjusting seat is supported on the slide rail by a second sliding roller, which includes a plurality of rollers and is spaced apart along the length of the slide rail.

[0013] Furthermore, the manual dragging unit is a hand chain hoist detachably disposed between the first conversion connection unit and the second conversion connection unit. The hand chain hoist is configured to drag the first conversion connection unit closer to the second conversion connection unit, so that the convex structure of the first conversion connection unit fits into the concave structure of the second conversion connection unit, and the pin hole of the convex structure aligns with the pin hole of the concave structure to allow the pin shaft to be inserted for connection.

[0014] Furthermore, there are multiple chain hoists connected between the first conversion connection unit and the second conversion connection unit, and each chain hoist is arranged side by side and connected individually to maintain a straight line during the forward movement of the first conversion connection unit and / or the second conversion connection unit, which can meet the connection accuracy requirements on site.

[0015] To achieve the above objectives, the present invention provides a cable connection construction method for anchoring caissons in water, comprising the following steps: S100. Before the caisson is launched from the dock, the slideway is first fixed on the top platform of the caisson; then the first adjusting seat, the open cable joint and the second adjusting seat are respectively installed on the slideway; S200. Use a hand chain hoist to connect the first and second adjustment seats together, thread the rope through the pre-drilled holes on the open cable joint one by one, and fix it with clips; After the S300 caisson is floated to the site, the anchoring boat carries the closed cable joint and anchor cable to one side of the caisson, and uses lifting equipment such as winches to lift it to the caisson platform and temporarily fix the anchor cable. S400. Use a crawler crane to place the closed cable joint on the first adjusting seat that has been installed on the slide. The first adjusting seat is provided with multiple semi-circular slots. The conical head of the closed cable joint automatically adapts to the semi-circular slots under its own weight, thereby adjusting the cable joint axis direction to be consistent with the slide axis direction. S500. The closed cable joint is rotated by adjusting bolts acting on the flat part of the closed cable joint, so that the plane of the flat part of the closed cable joint is perpendicular to the horizontal plane. After the S600 closed cable joint attitude adjustment is completed, use a hand-operated hoist to pull the first adjustment seat towards the second adjustment seat, so that the first conversion connection unit and the second conversion connection unit are engaged. Manually insert the pin shaft to complete the quick connection of the anchor cable and the winch.

[0016] The technical advantages of the cable connection device provided by this invention for anchoring construction of caissons in water are at least reflected in: 1. By setting detachable first and second conversion connection units on the slide, the rear end of the first conversion connection unit is connected to the positioning anchor via an anchor cable and the front end is provided with a convex connection part. The rear end of the second conversion connection unit is connected to the jack via a steel strand and the front end is provided with a concave connection part. By dragging the first and second conversion connection units close together by a manual dragging unit, the convex and concave connection parts are interlocked, so that the pin shaft can be inserted into the pin hole to quickly establish a connection relationship, realize the rapid connection of the anchor cable and the strand, shorten the installation time of the anchoring system, realize the rapid anchoring construction of the caisson, save construction time, reduce construction risks, and is suitable for situations where the volume is large and cannot be quickly placed by manual force. 2. The split structure of the first conversion connection unit facilitates the connection of the closed locking joint and the anchor cable on site, and also facilitates its placement on the first adjusting seat after connection, allowing for further back-and-forth movement on the slide rail. The split structure of the second conversion connection unit facilitates the connection of the open locking joint and the winch rope on site, and also facilitates its placement on the second adjusting seat after connection, allowing for further back-and-forth movement on the slide rail.

[0021] In deep-water conditions, caissons typically need to be assembled into a unified whole in a factory before being transported to the bridge site by floating. They are then submerged and precisely anchored under the constraint of an anchoring system. During the installation of the anchoring system, the connection of anchor cables and winches needs to be made on the floating caisson platform. However, flexible lifting and installation equipment cannot be installed on the caisson at this stage, making the installation process overly cumbersome and time-consuming. If the anchoring work cannot be completed, the caisson will remain floating on the water, and the risks will be difficult to control.

[0022] To address this, the present invention provides a cable connection device and construction method for anchoring caissons in water, comprising a slide rail, a first conversion connection unit, a second conversion connection unit, and a hand-operated dragging unit. The slide rail is fixedly installed on the top platform of the caisson. The first conversion connection unit is detachably slidably installed at the first end of the slide rail, with its rear end connected to a positioning anchor via an anchor cable and its front end having a convex connection portion. The second conversion connection unit is detachably slidably installed at the second end of the slide rail, with its rear end connected to a jack via a steel strand and its front end having a concave connection portion adapted to the convex connection portion. The hand-operated dragging unit is driven by the first conversion connection unit and / or the second conversion connection unit, configured to drive the convex connection portion of the first conversion connection unit and the concave connection portion of the second conversion connection unit to engage with each other, and a pin passes through the pin holes of the convex and concave connection portions. This enables rapid anchoring construction of the caisson, saving construction time and reducing construction risks.

[0023] The following description, along with the accompanying drawings and text, will help you understand the content of this invention and the differences between it and the prior art. The technical solutions (including preferred solutions) of this invention will be further described in detail below by way of the accompanying drawings and by listing some optional embodiments.

[0024] In this invention, when a specific device is described as being located between a first device and a second device, an intermediary device may or may not be present between the specific device and the first or second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other devices without an intermediary device, or it may be not directly connected to the other devices but have an intermediary device.

[0025] like Figures 1 to 7As shown, this invention provides a cable connection device for anchoring construction of caissons in water, including a slide rail 5, a first conversion connection unit 1, a second conversion connection unit 2, and a manual dragging unit. The slide rail 5 is fixedly installed on the top platform of the caisson. The first conversion connection unit 1 is detachably slidably installed at the first end of the slide rail 5, with its rear end connected to a positioning anchor via an anchor cable 6 and its front end having a convex connection portion. The second conversion connection unit 2 is detachably slidably installed at the second end of the slide rail 5, with its rear end connected to a jack via a steel strand and its front end having a concave connection portion adapted to the convex connection portion. The manual dragging unit is driven by the first conversion connection unit and / or the second conversion connection unit, configured to drive the convex connection portion of the first conversion connection unit and the concave connection portion of the second conversion connection unit to engage with each other, and is driven by a pin 3 passing through the pin holes of the convex and concave connection portions.

[0026] Based on the above embodiments, the present invention provides a cable connection device for anchoring construction of caissons in water. This device comprises a detachable first conversion connection unit 1 and a second conversion connection unit 2 installed on a slide. The rear end of the first conversion connection unit 1 is connected to a positioning anchor via an anchor cable 6, and the front end has a convex connection part. The rear end of the second conversion connection unit 2 is connected to a jack via a steel strand, and the front end has a concave connection part. By manually dragging the first conversion connection unit 1 and the second conversion connection unit 2 closer together, the convex and concave connection parts interlock, allowing the pin 3 to quickly establish a connection by inserting it into the pin hole. This enables rapid connection of the anchor cable 6 and the winch 7, shortens the installation time of the anchoring system, achieves rapid anchoring construction of the caisson, saves construction time, reduces construction risks, and is suitable for situations where the caisson is large and cannot be quickly lowered by manual force.

[0027] In some embodiments, the first conversion connection unit 1 includes a first adjusting seat 12 and a closed cable joint 11. The first adjusting seat 12 is slidably mounted on the slide rail 5, and the closed cable joint 11 is supported by the first adjusting seat 12. The anchor cable 6 is connected to the rear end of the closed cable joint 11, and the convex connecting part is disposed at the front end of the closed cable joint 11. The split structure of the first conversion connection unit 1 facilitates the connection of the closed cable joint 11 and the anchor cable 6 on site, and also facilitates its placement on the first adjusting seat 12 after connection, allowing for further back-and-forth movement on the slide rail 5.

[0028] The bottom of the first adjusting seat 12 is supported on the slide rail 5 by a first sliding roller 121. The first sliding roller 121 includes a plurality of rollers and is arranged at intervals along the length of the slide rail.

[0029] Furthermore, the front ends of the closed cable joint 11 are configured as flat structures. The first adjusting seat is provided with adjusting bolts 122 that press against the flat portions on both sides of the closed cable joint 11, so that the plane containing the flat portions of the closed cable joint 11 is perpendicular to the horizontal plane through the supporting adjustment effect of the adjusting bolts 122. The circumferential angle of the large-volume and heavy closed cable joint 11 can be adjusted simply by rotating the adjusting bolts 122, which facilitates the angle adjustment of the large-volume closed cable joint 11 and creates conditions for subsequent connection.

[0030] Furthermore, the first adjusting seat is provided with multiple semi-circular slots 123 spaced apart along the slide rail 5. The conical head of the closed cable joint 11 is adapted to the shape of the semi-circular slots 123 at the front end to adjust the axial direction of the closed cable joint 11 to be consistent with the axial direction of the slide rail 5.

[0031] In some embodiments, the second conversion connection unit 2 includes a second adjusting seat 22 and an open cable joint 21. The second adjusting seat 22 is slidably mounted on the slide rail 5, and the open cable joint 21 is supported by the second adjusting seat 22. The twisted rope 7 is connected to the rear end of the open cable joint 21, and the concave connecting part is provided at the front end of the open cable joint 21. The split structure of the second conversion connection unit 2 facilitates the connection of the open cable joint 21 and the twisted rope 7 on site, and also facilitates its placement on the second adjusting seat 22 after connection, allowing for further back-and-forth movement on the slide rail 5.

[0032] Furthermore, the second adjusting seat 22 is supported on the slide rail 5 by a second sliding roller 221, which includes a plurality of rollers and is spaced apart along the length of the slide rail.

[0033] The working principle of the cable connection device provided for anchoring construction of caissons on water is as follows: Before the caisson is launched from the dock, the open cable section 21 and the second adjusting seat 22 are welded together and installed on the slide rail 5. The winch 7 is threaded into the open cable section 21 one by one and anchored with clamps. After the caisson is floated to the construction site, the anchor boat carries one end of the closed cable section 11 of the anchor cable 6 to the side of the caisson. The closed cable section 11 is lifted to the caisson platform by the hoisting equipment such as the winch and placed on the first adjusting seat 12 that has been installed on the slide rail 5. The open cable section 21 will adjust its direction on the first adjusting seat under its own weight. Then, the opening direction of the cable section is adjusted by the adjusting bolt 122 on the first adjusting seat 12 so that the concave structure and the convex structure of the conversion joint are fitted together. Then, the unit is pulled by hand to pull the concave structure and the convex structure closer and threaded into the pin 3 to complete the rapid connection of the cable.

[0034] In some embodiments, the manual dragging unit is a hand chain hoist 4 detachably disposed between the first conversion connection unit 1 and the second conversion connection unit 2. The hand chain hoist 4 is configured to drag the first conversion connection unit 1 closer to the second conversion connection unit 2, so that the convex structure of the first conversion connection unit 1 fits into the concave structure of the second conversion connection unit 2, so that the pin hole of the convex structure aligns with the pin hole of the concave structure, so that the pin shaft 3 can be inserted for connection.

[0035] During implementation, multiple chain hoists 4 are connected between the first conversion connection unit 1 and the second conversion connection unit 2 respectively. Each chain hoist 4 is arranged side by side and connected individually to maintain a straight line during the forward movement of the first conversion connection unit 1 and / or the second conversion connection unit 2.

[0036] like Figure 8 As shown, the present invention provides a cable connection device and construction method for anchoring caissons in water, characterized by comprising the following steps: S100. Before the caisson is launched from the dock, the slide rail 5 is first fixed on the top platform of the caisson; then the first adjusting seat 12, the open cable joint 21 and the second adjusting seat 22 are respectively installed on the slide rail 5. S200. Use a hand chain hoist 4 to connect the first adjusting seat 12 and the second adjusting seat 22 together, thread the rope 7 through the pre-drilled holes on the open cable joint 21 one by one, and fix it with clips. S300. After the caisson is floated to the site, the anchor boat carries the closed cable joint 11 and anchor cable 6 to one side of the caisson, and uses lifting equipment such as winches to lift it to the caisson platform and temporarily fix the anchor cable 6. S400. Use a crawler crane to place the closed cable joint 11 on the first adjusting seat 12 that has been installed on the slide rail 5. The first adjusting seat 12 is provided with multiple semi-circular slots 123. The conical head of the closed cable joint 11 automatically adapts to the semi-circular slots 123 under its own weight, thereby adjusting the axial direction of the cable joint 11 so that it is consistent with the axial direction of the slide rail 5. S500. The closed cable joint 11 is driven to rotate by the adjusting bolt 122 acting on the flat part of the closed cable joint 11, so that the plane where the flat part of the closed cable joint 11 is located is perpendicular to the horizontal plane. After the closed cable joint 11 is adjusted, use the hand chain hoist 4 to pull the first adjusting seat 12 toward the second adjusting seat 22, so that the first conversion connecting unit 1 and the second conversion connecting unit 2 are engaged. Manually insert the pin 3 to complete the quick connection of the anchor cable 6 and the winch 7.

[0037] To reduce the installation time of mooring systems, a cable connection method is proposed during mooring construction. This method enables rapid connection of anchor cables and winches, shortening the installation time and reducing construction risks. Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of this specification. To more clearly illustrate the technical solution of this invention, specific embodiments are described below.

[0038] In practical implementation, the cable connection device for anchoring construction of caissons in water provided by the present invention includes a first conversion connection unit 1, a second conversion connection unit 2, a pin 3, a hand-operated hoist 4, and a slide rail 5. The first conversion connection unit 1 consists of a closed cable joint 11 and a first adjusting seat 12, with the anchor cable 6 connected to the closed cable joint 11. The second conversion connection unit 2 consists of an open cable joint 21 and a second adjusting seat 22, with a winch 7 fixed to the open cable joint 21. The first adjusting seat 12 is equipped with a sliding roller 121 and an adjusting bolt 122, while the second adjusting seat 22 is equipped with a sliding roller 221.

[0039] Before the caisson is launched, the slide 5 is fixed on the top platform of the caisson. Then, the first adjusting seat 12, the open cable joint 21 and the second adjusting seat 22 are installed on the slide 5. The first adjusting seat 12 and the second adjusting seat 22 are connected together by hand-operated hoist 4. The winch 7 is threaded into the reserved holes on the open cable joint 21 and fixed with clamps.

[0040] After the caisson is floated to the site, the anchoring boat carries the closed cable joint 11 and anchor cable 6 to one side of the caisson. Using a winch or other lifting equipment, it is lifted to the caisson platform, and the anchor cable is temporarily secured. A crawler crane then places the closed cable joint 11 onto the first adjusting seat 12, which is already installed on the slide rail 5. The first adjusting seat has multiple semi-circular slots 123. The conical head of the closed cable joint 11 automatically adapts to the semi-circular slots 123 under its own weight, thereby adjusting the axial direction of the cable joint 11 to align with the axial direction of the slide rail 5. Then, by applying adjusting bolts 122 to the flat portion of the closed cable joint 11, the joint is rotated around its axis, making the plane of the flat portion perpendicular to the horizontal plane.

[0041] After the closed cable section 11 is adjusted, the first adjusting seat 12 is pulled towards the second adjusting seat 22 by the hand chain hoist 4, and finally the first conversion connecting unit 1 and the first conversion connecting unit 2 are fitted together. The pin 3 is then manually inserted to complete the quick connection of the anchor cable and the winch.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
