The three-dimensional positioning device comprises a plurality of first moving mechanisms and a plurality of second moving mechanisms which are distributed along a front-rear direction at intervals. The plurality of first moving mechanisms and the plurality of second moving mechanisms are alternately distributed along the front-rear direction. The first moving mechanism has a first adjusting part and a first conveying part. The conveying channel of the first conveying part is distributed along the front-rear direction.

Description

Technical Field

[0001] This invention belongs to the field of steel box girder assembly technology, and particularly relates to a three-dimensional positioning device and splicing and transfer equipment. Background Technology

[0002] Steel box girders, also known as steel plate box girders, are a common structural form for long-span bridges. They are generally used on bridges with large spans and are called steel box girders because their shape resembles a box. In long-span cable-stayed bridges, the main span of the steel box girder can reach hundreds or even thousands of meters. They are generally manufactured and installed in several segments, and their cross-sections are characterized by their wide and flat shape. Steel box girders are generally composed of a top plate, bottom plate, web, transverse diaphragms, longitudinal diaphragms, and stiffening ribs, all connected by full welding. The assembly of steel box girders is a phased, multi-site collaborative process that can be carried out either in a specialized factory (manufacturing plant) or at the final location of the bridge (construction site).

[0003] When assembling steel box girders, the steel box girders are suspended and placed in the required position by lifting equipment. After placement, the error between the steel box girders to be assembled is relatively large, so the steel box girders cannot be directly assembled and fixed. Therefore, it is necessary to use lifting equipment to make fine adjustments to the position of the steel box girders. The accuracy of this adjustment and placement is relatively difficult to control, which increases the difficulty of assembling steel box girders. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, one of the objectives of the present invention is to provide a three-dimensional positioning device with a simple structure that can finely adjust the position of steel box girders in three-dimensional space during docking.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A three-dimensional positioning device includes a plurality of first moving mechanisms and a plurality of second moving mechanisms spaced apart along the front-back direction. The plurality of first moving mechanisms and the plurality of second moving mechanisms are alternately distributed in the front-back direction. The first moving mechanism has a first adjusting part and a first conveying part disposed on the first adjusting part. The conveying channel of the first conveying part is distributed along the front-back direction. The first adjusting part is used to adjust the tilt angle of the first conveying part in the left-right direction. The second moving mechanism has a second adjusting part and a second conveying part disposed on the second adjusting part. The conveying channel of the second conveying part is distributed along the left-right direction. The second adjusting part is used to adjust the height of the second conveying part.

[0006] The beneficial effect of the above-mentioned technical solution of the present invention is that when multiple steel box girders are placed in the front-back direction and distributed at intervals in the front-back direction on the three-dimensional adjustment device, one of the steel box girders can be used as a reference beam. Then, the positions of the other steel box girders are adjusted by the cooperation of the first moving mechanism and the second moving machine below them to align with the reference beam and fit together, so as to facilitate docking.

[0007] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, the first adjustment part includes a first base plate, a first top plate, a support base, and a telescopic drive component. The first base plate and the first top plate are both horizontally arranged in the left-right direction. The first top plate is located above the first base plate. The support base is vertically arranged in the middle of the upper part of the first base plate. The middle of the lower part of the first top plate is rotatably connected to the upper part of the support base in the left-right direction. The telescopic drive component is vertically arranged between the first base plate and the first top plate, and is located on the left or right side of the support base. The two ends of the telescopic drive component are respectively rotatably connected to the first top plate and the first base plate in the left-right direction. The first conveying part is arranged at the upper part of the first top plate.

[0008] The beneficial effect of the above-mentioned further technical solution is that it enables the first adjusting part to adjust the tilt angle of the corresponding first conveying part in the left and right directions, thereby adjusting the tilt angle of the steel box girder in the left and right directions.

[0009] Furthermore, two telescopic drive components are provided, and the two telescopic drive components are respectively located on both sides of the support base.

[0010] The beneficial effect of the above-mentioned further technical solution is that it enables the two telescopic drive members to coordinately adjust the tilt angle of the first conveying part in the left and right directions, thus making its support effect better.

[0011] Furthermore, the second adjustment part includes a second base plate, a second top plate, and a height adjustment component. Both the second base plate and the second top plate are horizontally arranged in the left-right direction. The second top plate is mounted on the second base plate through the height adjustment component, and the second conveying part is disposed on the second top plate.

[0012] The beneficial effect of the above-mentioned further technical solution is that the second adjustment part can adjust the horizontal height of the second conveying part, so that the second moving mechanism can lift the steel box beam upward to separate it from the first moving mechanism. When the steel box beam is separated from the first moving mechanism, it can drive the steel box beam to move left and right for fine adjustment. The second adjustment part can also drive the second conveying part to descend so that the steel box beam is placed on the first moving mechanism.

[0013] Furthermore, both the first conveying section and the second conveying section are roller conveyors.

[0014] The beneficial effects of the above-mentioned further technical solutions are: they provide excellent support stability and good load-bearing capacity.

[0015] The second objective of this invention is to provide a splicing and transfer device that can transfer steel box girders between the hoisting station and the splicing station.

[0016] To achieve the above objectives, the technical solution of the present invention is as follows: a splicing and transfer device includes a horizontally arranged base plate and a three-dimensional adjustment device as described above. A plurality of first moving mechanisms are arranged on the left or right side of the upper end of the base plate, and a plurality of second moving mechanisms are movably arranged on the base plate in the left-right direction. Each second moving mechanism can move in the left-right direction to between two corresponding first moving mechanisms.

[0017] The beneficial effects of the above-mentioned technical solution of the present invention are as follows: the multiple first moving mechanisms are fixedly installed on the upper end of the base plate, while the multiple second moving mechanisms are movable on the base plate in the front-back direction. This allows the steel box girder to be moved left and right by the multiple second moving mechanisms before and after splicing. Specifically, the transfer can be carried out at the hoisting station and the splicing station. The location of the multiple first moving mechanisms can be used as the splicing station, while the side of the base plate away from the splicing station can be used as the hoisting station.

[0018] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, the base plate is provided with multiple grooves spaced apart in the front-back direction along the left-right direction. Each of the multiple grooves corresponds to a multiple second moving mechanism. Multiple wheels are provided spaced apart in the left-right direction on both the front and rear sides of the second base plate, and the multiple wheels on each side of the second base plate are located in the corresponding grooves. The grooves are used to guide the second moving mechanism in the left-right direction.

[0019] The beneficial effect of the above-mentioned further technical solution is that the second moving mechanism moves by rolling on the base plate via wheels, and the groove can guide the movement direction of the wheels, thus preventing the second moving mechanism from deviating when moving in the left and right directions.

[0020] Furthermore, it also includes a support frame, which is disposed along the front-back direction on the upper side of the base plate away from the plurality of first moving mechanisms. The support frame is provided with a plurality of clearance slots spaced apart along the front-back direction, and the plurality of clearance slots correspond one-to-one with the plurality of second moving mechanisms and are aligned left and right. Each second moving mechanism can be moved to be accommodated in the corresponding clearance slot, and each second conveying part can be moved up and down to extend out of the corresponding clearance slot or be accommodated in the corresponding clearance slot.

[0021] The beneficial effect of the above-mentioned further technical solution is that: by setting the support frame at the hoisting station, multiple steel box girders can be pre-hoisted and placed on the support frame, and then the second moving mechanism of the corresponding segment will lift them up and separate them from the support frame, and transfer them to multiple first moving mechanisms of the corresponding segment. At this time, multiple first moving mechanisms and multiple second moving mechanisms cooperate to finely adjust multiple steel box girders to alignment and complete splicing. After the splicing is completed, the steel box girders are transferred together by multiple second moving mechanisms to be placed on the support frame.

[0022] Furthermore, it also includes a drive assembly, which is disposed on the base plate and has a plurality of drive ends spaced apart in the front-rear direction. The plurality of drive ends of the drive assembly correspond one-to-one with a plurality of second moving mechanisms. Each drive end of the drive assembly is drively connected to the corresponding second moving mechanism. The drive assembly is used to drive the plurality of second moving mechanisms to move synchronously in the left-right direction.

[0023] The beneficial effect of the above-mentioned further technical solution is that: such a plurality of second moving mechanisms can be driven by the drive assembly to move in the left and right directions at the same time, and the synchronicity of the movement of the plurality of second moving mechanisms in the left and right directions is good.

[0024] Furthermore, the drive assembly includes two spools, two first rotary drive members, two mounting seats, and multiple strands. The two spools, two first rotary drive members, and two mounting seats correspond one-to-one with each other. The two spools are horizontally arranged above the two sides of the base plate in the front-rear direction and are coaxially mounted on the base plate through the corresponding mounting seats. Each first rotary drive member is mounted on the corresponding mounting seat, and its drive end is connected to the corresponding spool. Each second base plate has at least one strand on each of its left and right sides. One end of each strand is connected to the corresponding second base plate, and the other end is pulled to connect with the spool on the corresponding side. If any one first rotary drive member drives the corresponding spool to wind up the strand, then the other first rotary drive member drives the corresponding spool to unwind the strand, so as to pull multiple second moving mechanisms to move synchronously in the left-right direction. The multiple strands on each second base plate together constitute one drive end of the drive assembly.

[0025] The beneficial effects of the above-mentioned further technical solution are that it has a simple structure, occupies little space, and the force applied to each of the second moving mechanisms is relatively balanced. Attached Figure Description

[0033] Example 1 like Figure 1 As shown, this embodiment provides a three-dimensional positioning device 100, including a plurality of first moving mechanisms 1 and a plurality of second moving mechanisms 2 distributed at intervals along the front-back direction. The plurality of first moving mechanisms 1 and the plurality of second moving mechanisms 2 are alternately distributed in the front-back direction. The first moving mechanism 1 has a first adjusting part 11 and a first conveying part 12 disposed on the first adjusting part 11. The conveying channel of the first conveying part 12 is distributed along the front-back direction. The first adjusting part 11 is used to adjust the tilt angle of the first conveying part 12 in the left-right direction. The second moving mechanism 2 has a second adjusting part 21 and a second conveying part 22 disposed on the second adjusting part 21. The conveying channel of the second conveying part 22 is distributed along the left-right direction. The second adjusting part 21 is used to adjust the height of the second conveying part 22. When multiple steel box girders 500 are placed along the front-to-back direction and distributed at intervals along the front-to-back direction on the three-dimensional adjustment device 100, one of the steel box girders 500 can be used as a reference beam. Then, the positions of the other steel box girders 500 are adjusted by the cooperation of the first moving mechanism 1 and the second moving mechanism below them to align with the reference beam and fit together, so as to facilitate docking.

[0034] like Figure 2As shown, in this embodiment, the first adjustment part 11 includes a first base plate 111, a first top plate 112, a support base 113, and a telescopic drive member 114. The first base plate 111 and the first top plate 112 are both horizontally arranged in the left-right direction. The first top plate 112 is located above the first base plate 111. The support base 113 is vertically arranged in the middle of the upper end of the first base plate 111. The middle of the lower end of the first top plate 112 is rotatably connected to the upper end of the support base 113 in the left-right direction through a first hinge seat 115. The telescopic drive member 114 is vertically arranged between the first base plate 111 and the first top plate 112, and is located on the left or right side of the support base 113. The two ends of the telescopic drive member 114 are respectively rotatably connected to the first top plate 112 and the first base plate 111 in the left-right direction through a second hinge seat 116. The first conveying part 12 is arranged at the upper end of the first top plate 112. This allows the first adjusting part 11 to adjust the tilt angle of the corresponding first conveying part 12 in the left-right direction, thereby adjusting the tilt angle of the steel box girder 500 in the left-right direction. In this embodiment, the telescopic drive component 114 can be a hydraulic cylinder or a telescopic electric cylinder.

[0035] In this embodiment, two telescopic drive members 114 are provided, and the two telescopic drive members 114 are respectively located on both sides of the support base 113. This allows the two telescopic drive members 114 to coordinately adjust the tilt angle of the first conveying part 12 in the left-right direction, thus improving its support effect.

[0036] like Figure 4 As shown, in this embodiment, the second adjustment unit 21 includes a second base plate 211, a second top plate 212, and a height adjustment component 213. Both the second base plate 211 and the second top plate 212 are horizontally arranged in the left-right direction. The second top plate 212 is mounted on the second base plate 211 via the height adjustment component 213, and the second conveying unit 22 is disposed on the second top plate 212. This allows the second adjustment unit 21 to adjust the horizontal height of the second conveying unit 22, enabling the second moving mechanism 2 to lift the steel box girder 500 upwards until it separates from the first moving mechanism 1. When the steel box girder 500 separates from the first moving mechanism 1, it can move the steel box girder 500 left and right for fine-tuning. The second adjustment unit 21 can also lower the second conveying unit 22 so that the steel box girder 500 is placed on the first moving mechanism 1. In this embodiment, the height adjustment component 213 can be a double scissor-type hydraulic lifting platform, or it can be a series of vertically arranged and spaced hydraulic cylinders.

[0037] In this embodiment, both the first conveying section 12 and the second conveying section 22 are roller conveyors. They have good support stability and good load-bearing capacity.

[0038] like Figure 2 and Figure 3 As shown, in this embodiment, the first conveying section 12 may be provided with only one first conveying roller 121 arranged in the left-right direction. In this embodiment, the first conveying roller 121 is provided, while the second conveying section 22 needs to be provided with multiple second conveying rollers 221 arranged horizontally in the front-back direction and spaced apart in the left-right direction.

[0039] like Figure 3 As shown, in this embodiment, since the first conveying section 12 has a large load-bearing capacity, the diameter of the first conveying roller 121 can be increased. To facilitate replacement, the first conveying section 12 also includes a U-shaped seat 122 and a second rotary drive 125. The U-shaped seat 122 is disposed on the first top plate 112 in a left-right direction (or the two are integrally formed). Rotating heads 123 are rotatably disposed at both ends of the U-shaped seat 122, and the two rotating heads are coaxially distributed. The second rotary drive 125 is disposed on the U-shaped seat 122, and its driving end is connected to either of the rotating heads 123. A receiving slot 1231 is recessed at the end of each of the two rotating heads 123 that is close to each other, and the rotating head corresponds to the receiving slot 1231. The side wall of the first conveyor roller 121 is provided with a placement notch 1232 and two aligned first pin holes 1233. Both ends of the first conveyor roller 121 have convex shafts 1211, and each of the two convex shafts 1211 has a second pin hole 1212. The first conveyor roller 121 is placed in the U-shaped seat 122 in the left-right direction, and both convex shafts 1211 at both ends can be inserted into the corresponding receiving slots 1231 through the placement notch 1232. Then, the first conveyor roller 121 is rotated until the second pin holes 1212 at both ends are aligned with the corresponding first pin holes 1233, and a pin 124 is inserted to assemble the first conveyor roller 121 onto the U-shaped seat 122, thus achieving a transmission connection with the second rotary drive component 125. In this embodiment, the second rotary drive component 125 can be a geared motor.

[0040] In this embodiment, when the position of the steel box girder 500 in the front-to-back direction needs to be fine-tuned, the multiple second moving mechanisms 2 below it lower the second conveying section 22 so that the steel box girder 500 rests on the multiple first conveying sections 12 below it. At this time, the multiple first conveying sections 12 below it drive the steel box girder 500 to move back and forth (at this time, the horizontal level of the steel box girder 500 can also be adjusted). When the position of the steel box girder 500 in the left-to-right direction needs to be fine-tuned, the multiple second moving mechanisms 2 below it raise the second conveying section 22 to lift the steel box girder 500. At this time, the multiple second conveying sections 22 below it drive the steel box girder 500 to move left and right (e.g., ...). Figure 5As shown, if the two ends of the steel box girder 500 are tilted in the left-right direction, that is, the steel box girder 500 and the second conveying roller 221 are not parallel, the multiple second conveying units 22 can adjust the difference in conveying speed to straighten the steel box girder 500 in the left-right direction. Figure 5 The dashed line represents a steel box girder in an inclined state (500).

[0041] Example 2 like Figure 6 As shown, this embodiment provides a splicing and transfer device, including a horizontally arranged base plate 200 and a three-dimensional positioning device 100 as described in Embodiment 1. A plurality of first moving mechanisms 1 are disposed on the left or right side of the upper end of the base plate 200, and a plurality of second moving mechanisms 2 are movably disposed on the base plate 200 in the left-right direction. Each second moving mechanism 2 can move in the left-right direction between two corresponding first moving mechanisms 1. This allows the plurality of first moving mechanisms 1 to be fixedly disposed at the upper end of the base plate 200, while the plurality of second moving mechanisms 2 are movably disposed on the base plate 200 in the front-back direction. This enables the steel box girder 500 to be transferred left and right by the plurality of second moving mechanisms 2 before and after splicing. Specifically, the transfer can be performed at the hoisting station and the splicing station. The location of the plurality of first moving mechanisms 1 can serve as the splicing station, while the side of the base plate 200 away from the splicing station can serve as the hoisting station.

[0042] like Figures 6-8 As shown, in this embodiment, the base plate 200 is provided with multiple grooves 210 spaced apart along the front-back direction in the left-right direction. Each groove 210 corresponds to one of the multiple second moving mechanisms 2. Multiple wheels 214 are spaced apart along the left-right direction on both the front and rear sides of the second base plate 211, and each wheel 214 on each side of the second base plate 211 is located within a corresponding groove 210. The grooves 210 guide the second moving mechanism 2 in the left-right direction. This allows the second moving mechanism 2 to roll on the base plate 200 via the wheels, and the grooves 210 guide the movement direction of the wheels, thus preventing the second moving mechanism 2 from deviating when moving in the left-right direction.

[0043] In this embodiment, the groove width of the groove 210 is slightly larger than the distance between the wheels on both sides of the second base plate 211 on one side away from each other, so that the wheels on both sides of the second base plate 211 can fall into the groove 210 and be guided by the groove 210.

[0044] In this embodiment, since the second base plate 211 is provided with wheels 214, each second base plate 211 can be configured as a chassis with its own power to drive the wheels to rotate, so that each second moving mechanism 2 has the function of moving independently in the left and right directions.

[0045] like Figures 6-8 As shown, in order to further improve the straightness of the second moving mechanism 2 when moving in the left and right direction, it is also possible to provide a sliding groove 220 on both sides of each groove 210 on the base plate 200, and to provide guide skirts 2111 on both sides of the second bottom plate 211 downwards, and the lower ends of the two guide skirts 2111 are inserted into the sliding grooves 220 and slidably connected with the base plate 200.

[0046] like Figure 6 As shown, the splicing and transfer device provided in this embodiment also includes a support frame 300. The support frame 300 is arranged along the front-back direction on the side of the upper end of the base plate 200 away from the plurality of first moving mechanisms 1. The support frame 300 is provided with a plurality of clearance grooves 310 distributed at intervals along the front-back direction. The plurality of clearance grooves 310 correspond one-to-one with the plurality of second moving mechanisms 2 and are aligned left and right. Each second moving mechanism 2 can be moved to be accommodated in the corresponding clearance groove 310. Each second conveying part 22 can be moved up and down to extend out of the corresponding clearance groove 310 or be accommodated in the corresponding clearance groove 310. By setting the support frame 300 at the hoisting station, multiple steel box girders 500 can be pre-hoisted and placed on the support frame 300. Then, the second moving mechanism 2 of the corresponding segment lifts them up and separates them from the support frame 300, and transfers them to multiple first moving mechanisms 1 of the corresponding segment. At this time, the multiple first moving mechanisms 1 and multiple second moving mechanisms 2 cooperate to finely adjust the multiple steel box girders 500 to alignment and complete the splicing. After the splicing is completed, the steel box girders 500 are transferred together by the multiple second moving mechanisms 2 to be placed on the support frame 300.

[0047] In order to improve the structural strength of the support frame 300, it is advisable to close the end of the clearance groove 310 away from the first moving mechanism 1, so that the entire support frame 300 is an integral structure, thereby having higher structural strength.

[0048] like Figure 6 and Figure 9As shown, the splicing and transfer device provided in this embodiment also includes a drive assembly 400. The drive assembly 400 is disposed on the base plate 200 and has multiple drive ends spaced apart along the front-rear direction. Each drive end of the drive assembly 400 corresponds one-to-one with a plurality of second moving mechanisms 2. Each drive end of the drive assembly 400 is drively connected to the corresponding second moving mechanism 2. The drive assembly 400 is used to drive the plurality of second moving mechanisms 2 to move synchronously in the left-right direction. In this way, the plurality of second moving mechanisms 2 can be driven simultaneously by the drive assembly 400 to move in the left-right direction, and the synchronicity of the movement of the plurality of second moving mechanisms 2 in the left-right direction is good.

[0049] like Figure 6 and Figure 9 As shown, the drive assembly 400 in this embodiment includes two spools 410, two first rotary drive members 420, two mounting seats 430, and multiple strands 440. The two spools 410, two first rotary drive members 420, and two mounting seats 430 correspond one-to-one. The two spools 410 are horizontally arranged above both sides of the base plate 200 along the front-rear direction and are coaxially rotatably mounted on the base plate 200 via their corresponding mounting seats 430. Each first rotary drive member 420 is mounted on its corresponding mounting seat 430, and its drive end is connected to the corresponding spool 410. At least one cable 440 is provided on each of the left and right sides of the second base plate 211. One end of each cable 440 is connected to the corresponding second base plate 211, and the other end is pulled to connect to the corresponding reel 410. If any one of the first rotary drive members 420 drives the corresponding reel 410 to wind up the cable 440, then another first rotary drive member 420 drives the corresponding reel 410 to unwind the cable 440, thereby pulling multiple second moving mechanisms 2 to move synchronously in the left and right direction. The multiple cables 440 on each second base plate 211 together constitute one drive end of the drive assembly 400. Its structure is simple, occupies little space, and the force applied to each second moving mechanism 2 is relatively balanced.

[0050] In this embodiment, the first rotary drive 420 can be a deceleration brake motor.

[0051] like Figure 6 and Figure 9 As shown, the drive assembly 400 in this embodiment can be divided into two winch units.
