Description

Technical Field

[0001] This invention relates to the field of crane vessel guide frame technology, specifically to a universal detachable guide frame for crane vessels and its construction method. Background Technology

[0002] Currently, there are two methods for constructing steel pipe piles in water: one is the fishing method based on a platform using a crawler crane, and the other is using a pile-driving vessel or a crane vessel with a guide frame.

[0003] However, the existing general-purpose detachable guide frame for crane vessels and the construction method have the following problems in use: In the traditional crane vessel plus guide frame scheme, the guide frame is independent in the water and separate from the crane vessel. This leads to problems such as low vessel investment, low construction efficiency (more procedures), greater construction safety (more vessels make anchoring troublesome, ship collisions, etc.), and limited construction space. Summary of the Invention

[0004] The purpose of this invention is to provide a universal detachable guide frame for crane vessels and a construction method to solve the problems mentioned in the background art, such as limited space (e.g., insufficient anchoring for existing bridges and trestle bridges) and the low construction efficiency due to the numerous steps involved in separately deploying the guide frame into the water. This invention addresses the difficulties in piling by using a small crane vessel with a guide frame.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a universal detachable guide frame for a crane vessel, comprising a support beam, a steel pipe pile, and a crane vessel body. A bracket assembly is welded to one side of the crane vessel body, and a second locking beam is fixed to the top of the bracket assembly via flange bolts. A first locking beam is installed on one side of the second locking beam via an inclined support frame. A support beam is installed at the top of the crane vessel body via flange bolts, and the support beam is connected to one side of the second and first locking beams via flange bolts. A hinge seat is installed on one side of the second locking beam, and a third locking beam is hinged to the outer wall of the hinge seat. Guide wheel support mechanisms are provided on the outer walls of the third, second, and first locking beams. The outer wall of the guide wheel support mechanism is in contact with the outer wall of the steel pipe pile. A pull-up lug is installed on one side of the third locking beam. An electric hoist is installed above the second locking beam, and the output end of the electric hoist is connected to the pull-up lug via a chain. A maintenance access assembly is provided above the second locking beam.

[0006] As a preferred embodiment of the universal detachable guide frame for crane vessels of the present invention, the bracket assembly includes a fixing plate and a pad block. A fixing plate is welded to one side of the crane vessel body, and a top plate is installed at the top of the web plate. A web plate connected to the outer wall of the crane vessel body is installed at the bottom of the fixing plate, and a limiting square tube is provided above the fixing plate.

[0007] As a preferred embodiment of the universal detachable guide frame for crane ships of the present invention, a pad block that fits against the second locking beam is provided above the top plate.

[0008] As a preferred embodiment of the universal detachable guide frame for crane vessels of the present invention, the guide wheel support mechanism includes a sleeve and a fixed lug. The fixed lug is installed on the outer wall of the sleeve, and the fixed lug is connected to the third locking beam, the second locking beam and the first locking beam by bolts. The inner wall of the sleeve is provided with a damping block, and the outer wall of the damping block is fitted with a roller frame that penetrates the sleeve. The inner wall of the roller frame is equipped with a positioning roller through a bearing.

[0009] As a preferred embodiment of the universal detachable guide frame for crane ships of the present invention, both the damping block and the outer wall of the roller frame are provided with rubber to increase wear resistance.

[0010] As a preferred embodiment of the universal detachable guide frame for crane ships of the present invention, a fixing block that penetrates the roller frame is installed inside the sleeve, and a T-shaped block that penetrates the fixing block is installed inside the roller frame, and a rigid spring and a tension spring that are connected to the outer wall of the fixing block are respectively sleeved on the outer wall of the T-shaped block.

[0011] As a preferred embodiment of the universal detachable guide frame for crane vessels of the present invention, the maintenance passage assembly includes a crossbar and a column. A crossbar is installed on one side of the second locking beam, and a column is installed at the top of the crossbar. A guardrail is installed at the top of the column, and a kick plate is installed on the inner side of the column.

[0012] As a preferred embodiment of the universal detachable guide frame for crane ships of the present invention, a pedestrian walkway is installed at the top of the crossbar.

[0013] A preferred embodiment of the construction method for a universal detachable guide frame for crane vessels according to the present invention includes the following steps: Step 1: Integrated installation of the guide frame: The bracket assembly is welded to one side of the crane vessel body, and the welded and spliced ​​first and second locking beams are fixed to the bracket assembly with flange bolts. Step 2: Positioning the crane vessel: Improving positioning accuracy by adding an anchor winch to the crane vessel body to control the piling accuracy; Step 3: Open the third locking beam: By starting the electric hoist, the chain pulls the lifting lugs, causing the third locking beam to rotate around the hinge seat; Step 4: Close the third locking beam after driving the pile: Drive the steel pipe pile to fit against the outer wall of the guide wheel support mechanism, then start the electric hoist to bring the lower part of the third locking beam into contact with the bottom end of the first locking beam via the chain, and the operator fixes it with bolts; Step 5, driving the pile: First, the steel pipe pile sinks under its own weight. When the depth of penetration exceeds 4m, turn on the vibratory hammer. The excitation force should not exceed 450KN. When the depth of penetration exceeds 8m, the excitation force can be gradually increased to the maximum. Step Six: Pile Driving Completed: Open the third locking beam of the guide frame, and then move the crane vessel body to complete the process.

[0014] The beneficial effects of the universal detachable guide frame for crane vessels and its construction method of the present invention are as follows: 1. This invention utilizes a crane vessel and guide frame as a whole for pile driving within a confined space. Considering the need for anchor winches to be fixed at the crane vessel body under adverse water conditions, the pile driving accuracy is improved. The guide frame incorporates the opening and closing function of the automatic third locking beam and the elastic extension and retraction function of the fully automatic guide wheel support mechanism, enabling unmanned pile driving positioning and thus meeting the pile driving accuracy requirements.

[0015] 2. This invention pre-welds the bracket assembly to the bow of the ship. The guide frame and the vertical wall of the bow are pressed together by the bracket assembly and the limiting square tube. As a result, the second locking beam is attached to the body of the crane ship through the pad block. It is fixed with flange bolts without welding, which reduces the number of personnel working near the edge and fully ensures the efficiency of personnel installation and dismantling.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1, such as Figure 1-5 As shown, the present invention provides a technical solution: a universal detachable guide frame for a crane vessel and a construction method thereof, comprising a support beam 1, steel pipe piles 9, and a crane vessel body 10. A bracket assembly 11 is welded to one side of the crane vessel body 10, and a second locking beam 3 is fixed to the top of the bracket assembly 11 by flange bolts. The bracket assembly 11 includes a fixing plate 1101 and a pad 1105. A fixing plate 1101 is welded to one side of the crane vessel body 10, and a top plate 1104 is installed at the top of the web plate 1102. The bottom end of the fixing plate 1101 is fitted with a component that is connected to the outer wall of the crane vessel body 10. The web plate 1102 is connected to the fixed plate 1101 and a limiting square tube 1103 is provided above it. A pad 1105 that fits against the second locking beam 3 is provided above the top plate 1104. By installing the guide frame as a whole with the hull, the bracket assembly 11 is first welded to the bow in advance. The guide frame and the vertical wall of the bow are pressed against the bracket assembly 11 and the limiting square tube 1103. Thus, the second locking beam 3 fits against the crane vessel body 10 through the pad 1105. The flange bolts are used for fixing without welding, reducing the need for personnel to work near the edge and fully ensuring the efficiency of personnel installation and dismantling.

[0020] Example 2, as Figure 1-4As shown, the present invention provides a technical solution: a universal detachable guide frame for crane vessels and a construction method, comprising a first locking beam 2 installed on one side of a second locking beam 3 via an inclined support frame; a support beam 1 installed on the top of the crane vessel body 10 via flange bolts, and the support beam 1 connected to one side of the second locking beam 3 and the first locking beam 2 via flange bolts; a hinge seat 5 installed on one side of the second locking beam 3; and a third locking beam 4 hinged to the outer wall of the hinge seat 5; and the third locking beam 4... Guide wheel support mechanisms 6 are provided on the outer walls of beam 4, the second locking beam 3, and the first locking beam 2. The outer wall of the guide wheel support mechanism 6 is in contact with the outer wall of the steel pipe pile 9. The guide wheel support mechanism 6 includes a sleeve 601 and a fixed lug 602. The fixed lug 602 is installed on the outer wall of the sleeve 601 and is bolted to the third locking beam 4, the second locking beam 3, and the first locking beam 2. A damping block 609 is provided on the inner wall of the sleeve 601, and the damping block 609 is externally... The sleeve is fitted with a roller frame 603 that penetrates the sleeve 601. A positioning roller 604 is mounted on the inner wall of the roller frame 603 via bearings. Both the damping block 609 and the outer wall of the roller frame 603 are lined with rubber to increase wear resistance. A fixing block 605 is installed inside the sleeve 601 that penetrates the roller frame 603. A T-shaped block 606 is installed inside the roller frame 603 that penetrates the fixing block 605. Rigid springs 607, which connect to the outer wall of the fixing block 605, are fitted onto the outer walls of the T-shaped blocks 606. The tension spring 608 is attached to the outer wall of the guide wheel support mechanism 6 via the steel pipe pile 9. Since the positioning roller 604 is attached to the outer wall of the steel pipe pile 9, the roller frame 603 moves on the outer wall of the damping block 609, thereby causing the T-block 606 to move backward, which causes the rigid spring 607 and tension spring 608 to undergo elastic deformation. Since the rigid spring 607 and tension spring 608 are elastic elements, the elastic force of the rigid spring 607 and tension spring 608 can meet the requirements of elastic automatic positioning.

[0023] Step 4: Close the third locking beam 4 after driving the pile: Drive the steel pipe pile 9 to the outer wall of the guide wheel support mechanism 6, then start the electric hoist 7 to bring the lower part of the third locking beam 4 into contact with the bottom end of the first locking beam 2 through the chain, and the operator fixes it with bolts; Step 5, driving the pile: First, the steel pipe pile 9 sinks under its own weight. When the depth of penetration exceeds 4m, turn on the vibratory hammer. The excitation force should not exceed 450KN. When the depth of penetration exceeds 8m, the excitation force can be gradually increased to the maximum. Step 6, pile driving completed: Open the third locking beam 4 of the guide frame, and then move the crane vessel body 10 to complete the process.

[0024] During construction: In a confined space, the crane vessel body 10 and guide frame are used for pile driving as a whole. Considering the need to fix anchor positions at the crane vessel body 10 under adverse water conditions, the pile driving accuracy is improved. The guide frame incorporates the opening and closing of the automatic third locking beam 4 and the elastic extension and retraction function of the fully automatic guide wheel support mechanism 6, realizing unmanned pile driving positioning, which can meet the pile driving accuracy requirements.
