A positioning device for steel beam transport pontoons

Abstract

This invention relates to the field of river transport technology for steel beams, specifically a positioning device for a steel beam transport pontoon. The upper end of a fan-shaped base plate is provided with multiple sets of reinforcing vertical plates arranged in a circular array. The reinforcing vertical plates abut against the lower end of a collar. One end of the fan-shaped base plate extends into the lower half-ring groove, and the squeezed half-ring is pressed against the upper surface of one end of the fan-shaped base plate. The beneficial effect is that, by utilizing the cooperation between the fan-shaped base plate and the reinforcing vertical plates, under a large traction force, when the anchor rod is subjected to unilateral traction, its inclined downward pressure acts on the fan-shaped base plate. This utilizes the large surface area of ​​the lower part of the fan-shaped base plate to distribute the downward pressure, preventing soil damage that could cause the anchor rod to loosen, and improving the installation strength and traction bearing capacity of the anchor rod.

Description

Technical Field

[0001] This invention relates to the field of river transport technology for steel beams, specifically a positioning device for a steel beam transport pontoon. Background Technology

[0002] When constructing bridges on non-navigable waterways, it is necessary to use pontoons to transport steel beams. The most common way to drive the pontoons is by pulling ropes.

[0003] In existing technologies, winches are typically used to pull the ropes, thereby driving the pontoon to move and adapt its position to the bridge's installation location. However, in actual driving and adjustment processes, anchor rods need to be installed on the riverbank to fix one end of the rope. Since the steel beams are large in volume and weight, a large traction force is required to drive and adjust the pontoon. The traction reaction force of the winch will directly act on the anchor rods, which can easily cause the rope to detach from the anchor rods. Furthermore, due to different directions of position adjustment, the rope needs to be switched between different anchor rods, and at this time, the rope is in a taut state and difficult to remove. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning device for a steel beam transport pontoon, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A positioning device for a steel beam transport pontoon, the positioning device comprising:

[0007] Anchors are installed on both sides of the river channel. The anchors include first anchor components and second anchor components. A hoisting platform for transporting steel beams is set on one side of the river channel. Three sets of second anchor components are set on the side of the river channel near the hoisting platform. Three sets of first anchor components are set on the other side of the river channel. A bridge is erected on the river channel. The three sets of second anchor components are distributed on both sides of the bridge. Two sets of second anchor components are set on the side near the hoisting platform.

[0008] The transport component includes a pontoon assembly and a traction rope. The steel beam is installed on the upper end of the pontoon assembly. Winches are installed at the four corners of the upper end of the pontoon assembly. The four winches are respectively connected to the first anchoring assembly and the second anchoring assembly via traction ropes. The ends of the first anchoring assembly and the second anchoring assembly that extend to the ground are equipped with collars. A rod is slidably inserted through the collar. The traction rope is sleeved on the collar and rotates one revolution along the rod.

[0009] The first anchoring component and the second anchoring component have upper and lower annular grooves on their sidewalls. A lifting and pressing half-ring is installed in the upper and lower annular grooves. The upper and lower annular grooves face the river channel. A fan-shaped base plate is provided on the outer side of the upper and lower annular grooves. Multiple sets of reinforcing vertical plates are arranged in a circular array at the upper end of the fan-shaped base plate. The reinforcing vertical plates abut against the lower end of the collar. One end of the fan-shaped base plate extends into the lower annular groove, and the pressing half-ring is pressed against the upper end face of one end of the fan-shaped base plate.

[0010] Preferably, the upper ends of the first anchoring component and the second anchoring component are both provided with stepped columns, the collar is vertically sleeved on the stepped columns, the outer wall of the middle arc of the collar is provided with a circular groove, and the end of the traction rope is sleeved in the circular groove.

[0011] Preferably, the upper end of the collar is provided with outer rings extending to the outside of the anchor, one side of the reinforcing vertical plate is attached to the outer wall of the anchor, and the upper end of the reinforcing vertical plate abuts against the lower end face of the lower outer ring.

[0012] Preferably, a first through hole is provided through the stepped column, and a second through hole is provided through the annular groove. The first through hole and the second through hole overlap, and the insertion rod is inserted into the first through hole and the second through hole.

[0013] Preferably, the upper end of the stepped column is provided with a mounting column, and a top cover that is pressed against the upper surface of the upper outer ring is vertically sleeved on the mounting column. The upper end of the top cover is provided with a locking nut that is threadedly rotatably mounted on the mounting column.

[0014] Preferably, an extended semi-ring is provided between the upper and lower semi-ring grooves. The extended semi-ring has multiple sets of through holes arranged in a circumferential array. The extrusion semi-ring is located in the lower semi-ring groove, and the upper end of the extrusion semi-ring has a connecting rod that corresponds to and is slidably inserted into the through holes. The upper end of the connecting rod has a fixing nut that is threaded, rotatably installed, and pressed against the upper end face of the extended semi-ring.

[0015] Preferably, the lower ends of the first anchoring component and the second anchoring component are pre-embedded and inserted into the ground.

[0016] Preferably, the fan-shaped base plate is pressed onto the ground, and the lower surface area of ​​the fan-shaped base plate is larger than the end face area of ​​the first anchoring component and the second anchoring component, and the end of the fan-shaped base plate is inserted into the lower semi-annular groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention improves the connection strength of the traction rope end by setting a connection between the collar and the insertion rod and utilizing the winding of the traction rope on the insertion rod, thereby preventing it from falling off. At the same time, when disassembling, pulling out the insertion rod loosens the traction rope at the end, making it easier to remove and switch positions.

[0019] By utilizing the combination of the fan-shaped base plate and the reinforcing vertical plate, when the anchor rod is subjected to unilateral traction under a large traction force, its inclined downward pressure acts on the fan-shaped base plate. This allows the large surface area of ​​the lower part of the fan-shaped base plate to distribute the downward pressure, preventing soil damage that could cause the anchor rod to loosen, and improving the installation strength and traction bearing capacity of the anchor rod.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 8 The present invention provides a technical solution:

[0031] The precast components used in the actual bridge hoisting construction include steel beam segments and steel-concrete segments. At the start of the hoisting, the precast components are hoisted onto the upper part of the floating box assembly 1 using the hoisting platform on the riverbank.

[0032] A positioning device for a steel beam transport pontoon, the positioning device comprising anchors and transport components.

[0033] First, the positioning of the steel-concrete section for transportation:

[0034] Anchors are installed on both sides of the river channel. The anchors include first anchor components 3 and second anchor components 4. A hoisting platform for transporting steel beams is set on one side of the river channel. Three sets of second anchor components 4 are set on the side of the river channel near the hoisting platform. Three sets of first anchor components 3 are set on the other side of the river channel. A bridge 5 is erected on the river channel. The three sets of second anchor components 4 are distributed on both sides of the bridge 5. Two sets of second anchor components 4 are set on the side near the hoisting platform. The three sets of first anchor components 3 are distributed on both sides of the bridge 5. Two sets of first anchor components 3 are set on the side near the hoisting platform. The transport components include a pontoon assembly 1 and a traction rope 2. The steel beam is installed on the upper end of the pontoon assembly 1. Winches are set at the four corners of the upper end of the pontoon assembly 1. The four winches are connected to the first anchor components 3 and the second anchor components 4 respectively through the traction rope 2.

[0035] like Figure 1 As shown, four sets of traction ropes 2 are first used to connect two sets of second anchoring components 4 and two sets of first anchoring components 3 on the side close to the hoisting platform, thereby pulling the pontoon assembly 1 located on the side of the hoisting platform. Under the action of the winch, the pontoon assembly 1 moves to the middle of the river.

[0036] like Figure 5 As shown, four sets of traction ropes 2 are connected to two sets of second anchoring components 4 and two sets of first anchoring components 3 near both sides of the bridge 5, thereby shortening the adjustment length of the traction ropes 2 and facilitating the precise alignment of the pontoon assembly 1 with the bridge 5.

[0037] Transportation and positioning of steel beam segments:

[0038] like Figure 6 As shown, four sets of traction ropes 2 are first used to connect two sets of second anchoring components 4 and two sets of first anchoring components 3 on the side close to the hoisting platform. Under the action of the winch, the floating box assembly 1 leaves the hoisting platform and moves to the middle of the river.

[0039] like Figure 7 As shown, the traction rope 2 is connected to the anchor rods near both sides of the bridge 5 to transport the pontoon assembly to the middle position of the bridge 5.

[0040] picture Figure 8 As shown, by changing the connection point of the traction rope 2, the longitudinally distributed float assembly 1 is deflected and distributed laterally along the bridge 5, achieving precise positioning adjustment.

[0041] During the above-mentioned adjustment and construction process, it is necessary to replace the connection between the end of the traction rope 2 and the anchor rod. Therefore, this application also has the following features:

[0042] Both the first anchoring component 3 and the second anchoring component 4 have stepped posts 6 at their upper ends. A collar 8 is vertically fitted onto the stepped post 6. A circular groove 10 is provided on the outer wall of the middle arc of the collar 8. The end of the traction rope 2 is fitted into the circular groove 10. The ends of the first anchoring component 3 and the second anchoring component 4 that extend to the ground are fitted with collars 8. A rod 23 is slidably inserted through the collar 8. The traction rope 2 is fitted onto the collar 8 and rotates one revolution along the rod 23. A first through hole 11 is provided through the stepped post 6, and a second through hole 22 is provided through the circular groove 10. The first through hole 11 and the second through hole 22 overlap. The rod 23 is inserted into the first through hole 11 and the second through hole 22.

[0043] The circular groove 10 is used to limit the position of the end of the traction rope 2 to prevent it from falling off. By wrapping the traction rope 2 around the insertion rod 23, the connection strength between the traction rope 2 and the collar 8 is further improved. At the same time, during disassembly, the traction rope 2 can be contacted in a taut state simply by pulling out the insertion rod 23, which makes it easy to change the end position of the traction rope 2.

[0044] During the traction process, the lower ends of the first anchoring component 3 and the second anchoring component 4 are pre-embedded and inserted underground. The reaction force of the traction acts on the first anchoring component 3 and the second anchoring component 4, which can easily cause the first anchoring component 3 and the second anchoring component 4 to damage the soil layer under the action of a large traction force. Therefore, this application also has the following features:

[0045] A mounting post 7 is provided at the upper end of the stepped post 6. A top cover 12 is vertically sleeved on the mounting post 7 and pressed onto the upper surface of the upper outer ring 9. A locking nut 13 is provided at the upper end of the top cover 12 and is rotatably mounted on the mounting post 7.

[0046] The position of the collar 8 is limited by the top cover 12 to prevent the collar 8 from falling off.

[0047] The first anchoring component 3 and the second anchoring component 4 are provided with an upper semi-annular groove 14 and a lower semi-annular groove 16 on their sidewalls. A lifting and lowering extrusion semi-ring 17 is installed in the upper semi-annular groove 14 and the lower semi-annular groove 16. The upper semi-annular groove 14 and the lower semi-annular groove 16 face the river channel. A fan-shaped base plate 18 is provided on the outer side of the upper semi-annular groove 14 and the lower semi-annular groove 16. Multiple sets of reinforcing vertical plates 19 are arranged in a circular array at the upper end of the fan-shaped base plate 18. The reinforcing vertical plates 19 abut against the lower end of the collar 8. One end of the fan-shaped base plate 18 extends to... In the lower half-ring groove 16, the extruded half-ring 17 is pressed against the upper end face of one end of the fan-shaped base plate 18. The upper ends of the collar 8 are provided with outer rings 9 extending to the outside of the anchor. One side of the reinforcing vertical plate 19 is attached to the outer wall of the anchor. The upper end of the reinforcing vertical plate 19 abuts against the lower end face of the lower outer ring 9. The fan-shaped base plate 18 is pressed against the ground. The lower end surface area of ​​the fan-shaped base plate 18 is greater than the end face area of ​​the first anchor component 3 and the second anchor component 4. The end of the fan-shaped base plate 18 is inserted into the lower half-ring groove 16.

[0048] By setting up a reinforcing vertical plate 19, the compressive force caused by the unidirectional offset of the first anchoring component 3 and the second anchoring component 4 under the action of traction is transmitted to the fan-shaped base plate 18. The large surface area of ​​the lower end of the fan-shaped base plate 18 is used to share the downward pressure, avoiding soil damage that could cause the anchor rod to loosen, thereby improving the installation strength and traction bearing capacity of the anchor rod.

[0049] During the pressure-bearing process, due to the different pre-embedded depths of the anchors, the fan-shaped base plate 18 and the reinforcing vertical plate 19 are difficult to form effective support with the anchors. Therefore, this application also has the following features:

[0050] An extended semi-ring 15 is provided between the upper semi-ring groove 14 and the lower semi-ring groove 16. The extended semi-ring 15 is provided with multiple sets of through holes arranged in a circumferential array. The extrusion semi-ring 17 is located in the lower semi-ring groove 16. The upper end of the extrusion semi-ring 17 is provided with a connecting rod 21 that corresponds to and is slidably inserted into the through holes. The upper end of the connecting rod 21 is provided with a fixing nut 20 that is threadedly rotated and pressed onto the upper end face of the extended semi-ring 15.

[0051] By setting the connecting rod 21 and the fixing nut 20, the height of the extrusion half ring 17 can be adjusted. Since the lower half ring groove 16 is set so that one end of the fan-shaped base plate 18 can be inserted and extended, the height can be adjusted by using the connecting rod 21, so that the extrusion half ring 17 is pressed onto the fan-shaped base plate 18 and fixed by the fixing nut 20. This facilitates the transmission of the traction force on the anchor to the fan-shaped base plate 18, and is suitable for anchor support with different pre-embedded depths.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
