Description

Technical Field

[0001] The invention relates to the field of arch bridge construction, and in particular to a device and method for safely and quickly assembling ultra-wide steel box tie arch rib segments. Background Art

[0002] The arch bridge includes a beam body and an arch body. The arch body is located on the beam body. The arch body includes arch ribs, and the arch ribs are assembled and fixed by multiple arch rib segments.

[0003] The current construction method of the bottom-supported arch bridge includes the steps of installing the arch rib segment, pushing the beam and arch as a whole, and disassembling the arch rib assembly frame. In the process of installing the arch rib segment, the arch rib assembly frame is first installed on the beam body, and then the arch rib segment is hoisted to the top of the arch rib assembly frame. The arch rib assembly frame supports the arch rib segment, and then the adjacent arch rib segments are assembled, and the arch rib segment and the arch rib assembly frame are fixed by the frame fixing structure. After the entire arch rib is assembled, the beam body and the arch body form a beam-arch structure, and the beam arch is subsequently pushed as a whole. After the beam arch top is pushed into place, the arch rib assembly frame is disassembled.

[0004] At present, when the arch rib segments are hoisted to the top of the arch rib assembly frame, the arch rib segments are often unable to be pre-fixed quickly and accurately. During the installation process of the arch rib segments, there is a lack of a complete set of rapid positioning devices. The segments to be installed swing greatly when hoisted, and the positioning posture adjustment time is long, which is not convenient for the rapid installation of the arch rib segments and the accurate fixation of the frame fixing structure. Summary of the invention

[0005] The present invention aims to provide a safe and quick fixing device and method for assembling ultra-wide steel box tie rod arch rib segments, so as to achieve clamping and fixing of the arch rib segments, and realize quick positioning and accurate fixing of the arch rib segments during installation, so as to facilitate the subsequent installation of the arch rib segments and the fixation of the tire frame fixing structure.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a safe and quick fixing device for assembling ultra-wide steel box tie rod arch rib segments, comprising an operating platform and a positioning adjustment unit located on the operating platform; the number of the positioning adjustment units is multiple, and the multiple positioning adjustment units are respectively a left positioning adjustment unit for positioning the left side of the arch rib segment and a right positioning adjustment unit for positioning the right side of the arch rib segment.

[0007] The principle and advantage of this scheme are: the operating platform in this scheme is fixed on the arch rib assembly frame, the positioning and adjustment unit is installed on the operating platform, and the positioning and adjustment unit is used to position and pre-fix the arch rib segment. Therefore, when installing the arch rib segment, the arch rib segment is hoisted onto the arch rib assembly frame, the left positioning and adjustment unit is located on the left side of the arch rib segment, and the right positioning and adjustment unit is located on the right side of the arch rib segment. The left positioning and adjustment unit and the right positioning and adjustment unit clamp the left and right sides of the arch rib segment, thereby realizing the positioning and preliminary fixation of the arch rib segment. The arch rib segment will not tilt and move left and right on the arch rib assembly frame, reducing the swing amplitude of the arch rib segment when hoisting. The arch rib segment is more stable on the arch rib assembly frame, which is conducive to reducing the time for adjusting the posture of the arch rib segment, improving the accuracy, convenience and speed of the subsequent fixed installation of the arch rib segment, and also facilitating the accurate fixation of the subsequent frame fixing structure. Through the scheme of this application, the arch rib segment can be quickly and safely positioned and pre-fixed, which is conducive to speeding up the construction process and improving construction safety.

[0008] Preferably, as an improvement, the positioning adjustment unit comprises a base and a clamping plate, the clamping plate is tiltedly arranged on the base; the tilting angle of the clamping plate is adjustable; the clamping plate is laterally slidably connected to the base.

[0009] Thus, the clamping plate is tilted to adapt to the tilted side of the arch rib segment, so that the clamping plate can better clamp the tilted side of the arch rib segment. The tilt angle of the clamping plate is adjustable, so that the clamping plate can be changed according to the actual situation of the tilt of the side of the arch rib segment, so that the clamping plate is parallel to the side of the arch rib segment, so that it can be suitable for clamping the side of the arch rib segment with different tilt angles. The clamping plate can slide on the base, so that the distance between the clamping plate of the left positioning adjustment unit and the clamping plate of the right positioning adjustment unit is adjustable, so that arch rib segments of different widths can be clamped.

[0010] Therefore, the present application adjusts the inclination angle of the clamping plate and the position of the clamping plate on the base so that the clamping plate can clamp and fix arch rib segments of different specifications (different specifications refer to different widths of the arch rib segments or sides with different inclination angles).

[0011] Preferably, as an improvement, an oblique driving member for pushing the clamping plate for angle adjustment is fixedly provided on the base; a first connecting part is slidably connected to the side of the clamping plate, and a driving rod of the oblique driving member is rotatably connected to the first connecting part.

[0012] Thus, the clamping plate is driven to rotate on the base through the oblique driving member, thereby realizing the adjustment of the inclination angle of the clamping plate. At the same time, the oblique driving member also has a supporting function for the clamping plate. When the oblique driving member is stationary, the clamping plate can maintain a stable inclination state, thereby stably clamping the arch rib segment.

[0013] When the oblique driving member is extended and retracted, the driving rod of the oblique driving member drives the first connecting part to slide on the clamping plate, and the first connecting part drives the clamping plate to swing, thereby realizing the adjustment of the inclination angle of the clamping plate.

[0014] Preferably, as an improvement, a transverse driving member for pushing the clamping plate to slide is fixedly provided on the base; a second connecting part is slidably connected to the base, a driving rod of the transverse driving member is connected to the second connecting part, and the bottom of the clamping plate is rotatably connected to the second connecting part.

[0015] Thus, the second connection part is driven by the transverse driving member, the second connection part slides on the base, and the second connection part drives the clamping plate to move, thereby realizing the sliding of the clamping plate on the base. At the same time, the bottom of the clamping plate is rotatably connected to the second connection part, so that the clamping plate can rotate on the base to adjust the inclination angle of the clamping plate.

[0016] In the present application, the transverse drive and the oblique drive cooperate with each other to achieve the adjustment of the position of the clamping plate on the base and the adjustment of the angle of the clamping plate. For example, when the transverse drive is stationary and the oblique drive is extended and retracted, the second connection part is in a stationary state, and the bottom of the clamping plate rotates on the second connection part, thereby achieving the angle adjustment of the clamping plate; when the transverse drive is extended and retracted, the oblique drive is stationary, and the second connection part is in a sliding state, and the clamping plate rotates relative to the first connection part, thereby also achieving the angle adjustment of the clamping plate; when the transverse drive and the oblique drive are extended and retracted at the same time, and the extension ratio of the two is the same, the inclination angle of the clamping plate remains unchanged, and the position of the clamping plate only changes; when the transverse drive and the oblique drive are extended and retracted at the same time, and the extension ratio of the two is different, the inclination angle of the clamping plate and the position of the clamping plate will change to a certain extent. Therefore, through the cooperation between the transverse drive and the oblique drive, the adjustment of the clamping plate is more flexible and can be adapted to arch rib segments of different specifications.

[0017] Preferably, as an improvement, a fine-tuning component is installed on the side of the clamping plate.

[0018] Thus, the fine-tuning component is installed on the clamping plate, and the fine-tuning component clamps the side of the arch rib segment against each other. The reason why the fine-tuning component is provided in the present application is that in the actual construction process, even after the position and angle of the clamping plate are adjusted, the adjustment of the clamping plate is only a rough adjustment, and there may still be a gap between the clamping plate and the arch rib segment, thereby affecting the clamping positioning and fixing effect. For this reason, a fine-tuning component is provided in the present application, and the fine-tuning component is fine-adjusted according to the gap between the clamping plate and the side of the arch rib segment, and the extension length of the fine-tuning component is changed. The fine-tuning component can fill the gap between the clamping plate and the side of the arch rib segment, and the fine-tuning component is pressed against the side of the arch rib segment, thereby improving the stability of the clamping and fixing of the arch rib segment.

[0019] To achieve the above purpose, the present invention also adopts the following technical solution: a method for safely and quickly assembling and fixing ultra-wide steel box tie rod arch rib segments, using the above ultra-wide steel box tie rod arch rib segment safe and quick fixing assembly device to position and fix the arch rib segments.

[0020] Preferably, as an improvement, the method comprises the following steps: S1. Install an operating platform on an arch rib assembly frame, and install multiple positioning adjustment units on the operating platform; the positioning adjustment units on the operating platform are arranged in two rows, left and right, and the two rows of positioning adjustment units are left positioning adjustment units and right positioning adjustment units, respectively, and the left positioning adjustment units and the right positioning adjustment units are arranged opposite to each other; S2, hoisting the arch rib segment between the left positioning and adjusting unit and the right positioning and adjusting unit; S3, the left positioning adjustment unit and the right positioning adjustment unit respectively abut the left and right sides of the arch rib segment to achieve positioning and pre-fixation of the arch rib segment; S4, installing a tire frame fixing structure, the tire frame fixing structure connects and fixes the arch rib assembly tire frame and the arch rib segment; S5. Remove the positioning adjustment unit.

[0021] Preferably, as an improvement, in S1, the number of positioning adjustment units in both the left and right rows is two.

[0022] Preferably, as an improvement, in S1, a support rod is connected between the operating platform and the arch rib assembly frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is further described in detail through specific implementation methods: The figure marks in the drawings of the specification include: arch rib segment 1, beam body 2, arch rib assembly frame 3, operating platform 4, support platform 5, positioning adjustment unit 6, clamping plate 60, oblique driving member 61, base 62, lateral driving member 63, fine-tuning component 64, second connecting part 65, first connecting part 66, accommodating groove 67, and frame fixing structure 7.

[0029] Example 1 Basically as attached Figure 1-Figure 4 As shown: This embodiment discloses a safe and quick fixing device for assembling ultra-wide steel box tie rod arch rib segments, including an operating platform 4 and a positioning adjustment unit 6 located on the operating platform 4; the number of the positioning adjustment units 6 is multiple, and the multiple positioning adjustment units 6 are respectively a left positioning adjustment unit for positioning the left side of the arch rib segment 1 and a right positioning adjustment unit for positioning the right side of the arch rib segment 1.

[0030] Combination Figure 1 As shown, the built beam arch in this embodiment includes a beam body 2, a plurality of groups of arch rib assembly frames 3 ( Figure 1 Each group of arch rib assembly frames 3 is composed of 2 or 3 arch rib assembly frames 3, and the tops of the arch rib assembly frames 3 of each group are close to each other) and the arch ribs assembled by multiple arch rib segments 1 located on the top of the arch rib assembly frames 3. Figure 2 As shown, Figure 2 The figure shows a structure in which a group of arch rib assembly frames 3 support an arch rib segment 1. This structure is taken as an example to explain the specific structure and use of the ultra-wide steel box tie rod arch rib segment assembly safe and fast fixing device in this embodiment.

[0031] Figure 2 A set of arch rib assembly frames 3 is equipped with an operating platform 4, which is detachably fixed to the arch rib assembly frame 3 by means of support rods and bolts. A positioning adjustment unit 6 is installed on the operating platform 4, or in some other embodiments, a support table 5 is provided on the operating platform 4, and a positioning adjustment unit 6 is installed on the support table 5. Figure 2 and Figure 3 As shown, in this embodiment, the number of positioning adjustment units 6 on the operating table is four. Figure 2 Two of the positioning adjustment units 6 are located on the left side of the arch rib assembly frame 3 in the figure, and two positioning adjustment units 6 are located on the right side of the arch rib assembly frame 3 in the figure; combined Figure 3 As shown, the two positioning adjustment units 6 located on the left side of the arch rib segment 1 are left positioning adjustment units, and the two positioning adjustment units 6 located on the right side of the arch rib segment 1 are right positioning adjustment units. The two left positioning adjustment units and the two right positioning adjustment units are arranged one by one opposite to each other, so as to clamp the left and right sides of the arch rib segment 1.

[0032] Combination Figure 3 As shown, the positioning adjustment unit 6 in this embodiment includes a base 62 and a clamping plate 60. The base 62 is detachably connected to the operating platform 4 or the support platform 5 of the operating platform 4 by bolts, and the clamping plate 60 is tiltedly arranged on the base 62. The bottom of the clamping plate 60 is rotatably connected to the base 62, and the specific rotatable connection method is: a second connecting portion 65 that can slide laterally is provided on the base 62, and the second connecting portion 65 and the bottom of the clamping plate 60 are connected by a rotating shaft, thereby, the clamping plate 60 is rotated on the second connecting portion 65, thereby realizing the angle adjustment between the clamping plate 60 and the base 62.

[0033] In order to facilitate the adjustment of the inclination angle of the clamping plate 60, an oblique driving member 61 for pushing the clamping plate 60 for angle adjustment is fixedly provided on the base 62, and the oblique driving member 61 is a lifting structure such as an oil cylinder, an air cylinder, an electric or a mechanical one. The bottom end of the oblique driving member 61 is fixed on the base 62, for example, by bolts, and the end of the driving rod of the oblique driving member 61 is connected to the clamping plate 60. In this embodiment, the side of the clamping plate 60 away from the arch rib segment 1 is vertically slidably connected with a first connecting portion 66, and the driving rod of the oblique driving member 61 is rotatably connected to the first connecting portion 66 through a pin shaft, so that through the extension and retraction of the driving rod of the oblique driving member 61, the driving rod drives the clamping plate 60 to rotate on the second connecting portion 65 through the first connecting portion 66, thereby realizing the adjustment of the inclination angle of the clamping plate 60. In this embodiment, the first connection part 66 is slidably arranged on the clamping plate 60, so that when the driving rod of the oblique driving member 61 drives the first connection part 66, the first connection part 66 can move appropriately on the clamping plate 60, avoiding the situation that the first connection part 66 is fixed on the clamping plate 60 and the driving rod of the oblique driving member 61 cannot drive the clamping plate 60 to rotate. In this embodiment, the specific way of sliding the first connection part 66 and the clamping plate 60 can be: a vertical T-shaped sliding groove is provided on the side of the clamping plate 60, and a T-shaped sliding part is provided on the first connection part 66, and the sliding part is located in the sliding groove.

[0034] The bottom of the clamping plate 60 in this embodiment is slidably connected to the base 62. Specifically, the second connecting portion 65 slides horizontally on the base 62, thereby realizing the horizontal sliding of the clamping plate 60. The specific sliding mode of the second connecting portion 65 and the base 62 is as follows: a horizontal T-shaped slide groove is provided on the base 62, and a T-shaped sliding portion is provided on the second connecting portion 65, and the sliding portion is located in the slide groove. A horizontal driving member 63 for pushing the clamping plate 60 to slide is fixed (for example, fixed by bolts) on the base 62 in this embodiment. The horizontal driving member 63 is a lifting structure such as an oil cylinder, an air cylinder, an electric or a mechanical one. The driving rod of the horizontal driving member 63 is connected to the second connecting portion 65. In this way, the second connecting portion 65 is driven to slide on the base 62 by the extension and contraction of the driving rod of the horizontal driving member, thereby realizing the adjustment of the horizontal position of the clamping plate 60.

[0035] The oblique driving member 61 in this embodiment is arranged obliquely, and the oblique driving member 61 has a supporting function for the clamping plate 60. The oblique driving member 61, the transverse driving member 63 and the clamping plate 60 form a triangular structure. According to the triangle stability principle, when the lengths of the oblique driving member 61 and the transverse driving member 63 are fixed, the clamping plate 60 is more stable on the base 62, and the clamping plate 60 can stably clamp the arch rib segment 1.

[0036] In this embodiment, when adjusting the inclination angle of the clamping plate 60, the transverse driving member 63 can be placed in a fixed state, and the first connecting portion 66 drives the clamping plate 60 to swing by the extension and contraction of the driving rod of the oblique driving member 61, so as to adjust the inclination angle of the clamping plate 60, and at this time, the bottom end of the clamping plate 60 rotates around the second connecting portion 65. Of course, it is also possible to place the oblique driving member 61 in a fixed state, and the second connecting portion 65 drives the clamping plate 60 to swing by the extension and contraction of the driving rod of the transverse driving member 63, so as to adjust the inclination angle of the clamping plate 60, and at this time, the clamping plate 60 rotates relative to the first connecting portion 66, and the transverse position of the bottom of the clamping plate 60 also changes. Of course, it is also possible to adjust the position and angle of the clamping plate 60 by the joint extension and contraction of the oblique driving member 61 and the transverse driving member 63 (if the extension and contraction ratios of the oblique driving member 61 and the transverse driving member 63 are the same, the inclination angle of the clamping plate 60 remains unchanged, and only the position changes). Therefore, the present application makes the adjustable range of the clamping plate 60 more flexible by setting the oblique driving member 61 and the transverse driving member 63 and controlling the extension and retraction of the oblique driving member 61 or the transverse driving member 63, so that it can adapt to arch rib segments 1 of different specifications (different specifications refer to different side inclination angles of the arch rib segments 1 or different widths of the arch rib segments 1).

[0037] In addition, in other embodiments, a plurality of fine-tuning components 64 are also installed (for example, installed by bolts) on the side of the clamping plate 60 facing the arch rib segment 1. The fine-tuning component 64 can be a fine-tuning cylinder, a fine-tuning oil cylinder, an electric or mechanical fine-tuning lifting component. In this way, after the position and angle of the clamping plate 60 are roughly adjusted by the oblique driving member 61 and the lateral driving member 63, the arch rib segment 1 is placed between the clamping plate 60 of the left positioning adjustment unit and the clamping plate 60 of the right positioning adjustment unit, and then the fine-tuning component 64 is extended and retracted, and the side of the arch rib segment 1 is tightly pressed against each other by the fine-tuning component 64, so that the arch rib segment 1 can be more accurately positioned and initially fixed.

[0038] This embodiment also discloses a method for safely and quickly assembling and fixing an ultra-wide steel box tie rod arch rib segment. The ultra-wide steel box tie rod arch rib segment safely and quickly assembling and fixing device in this embodiment is used to position and fix the arch rib segment. The specific steps are as follows: S1. First, build an arch rib assembly frame 3 on the beam body 2, and then install an operating platform 4 on the arch rib assembly frame 3. The bottom of the operating platform 4 is fixed to the arch rib assembly frame 3 by means of support rods and bolts; and install multiple positioning adjustment units 6 on the operating platform 4. The positioning adjustment units on the operating platform 4 are arranged in two rows, left and right, and the left and right rows of positioning adjustment units are respectively left positioning adjustment units and right positioning adjustment units, and the left positioning adjustment units and the right positioning adjustment units are arranged oppositely; in this embodiment, the number of the left and right rows of positioning adjustment units is two.

[0039] S2. According to the width of the arch rib segment 1 and the side inclination angle of the arch rib segment 1, the position and angle of the clamping plate 60 on the positioning adjustment unit 6 are preliminarily adjusted, and then the arch rib bracket is hoisted between the left positioning adjustment unit and the right positioning adjustment unit.

[0040] S3, and then adjust the position and angle of the clamping plate 60 so that the position and angle of the clamping plate 60 are more suitable for the corresponding specifications of the arch rib segment 1. At this point, the coarse adjustment of the position and angle of the clamping plate 60 is completed, and then the fine adjustment component 64 is adjusted so that the fine adjustment component 64 is pressed against the side of the arch rib segment 1, so that the positioning and adjustment unit 6 can position and preliminarily fix the arch rib segment 1.

[0041] S4. After the arch rib segment 1 is positioned and preliminarily fixed, the adjacent arch rib segments 1 are fixed (for example, by welding) and a tire frame fixing structure 7 (the tire frame fixing structure 7 is specifically a structure formed by welding steel plates) is installed on the top of the arch rib assembly tire frame 3. The tire frame fixing structure 7 connects and fixes the arch rib segment 1 and the arch rib assembly tire frame 3 (the fixing method is, for example, welding).

[0042] S5. After the arch rib segments 1 on the arch rib assembly tyre 3 of each group are installed and the tyre fixing structure 7 is installed and fixed, the positioning and adjustment unit 6 is removed and moved to other arch rib assembly tyres 3 to position and preliminarily fix other arch rib segments 1 in the above manner, and the installation of the arch rib segments 1 in other parts and the fixation of the tyre fixing structure 7 are completed.

[0043] Example 2 The fine-tuning component 64 of Example 1 protrudes from the surface of the clamping plate 60, so that in the process of lowering the arch rib segment 1 between the clamping plate 60 of the left positioning adjustment unit and the clamping plate 60 of the right positioning adjustment unit, the fine-tuning component 64 may hinder the lowering of the arch rib segment 1, and the bottom of the arch rib segment 1 may be stuck on the upper fine-tuning component 64, thereby affecting the lowering of the arch rib segment 1. At the same time, the bottom of the arch rib segment 1 may damage the fine-tuning component 64 after colliding with the fine-tuning component 64 above the clamping plate 60, affecting the service life of the fine-tuning component 64. In addition, the device in Example 1 mainly plays the role of clamping and fixing the arch rib segment 1, so that the arch rib segment 1 can be accurately installed. Figure 3 The middle position of the top of the left and right arch rib assembly frame 3 has little effect. After the arch rib segment 1 is hoisted to the top of the arch rib assembly frame 3, it may Figure 3 There is a small deviation to the left or right in the direction, so that the adjacent arch rib segments 1 may not be aligned and have a small misalignment, which is not conducive to fixing the adjacent arch rib segments 1.

[0044] To this end, this embodiment is further improved on the basis of embodiment 1. In this embodiment, the fine-tuning component 64 is hidden on the clamping plate 60. Specifically, Figure 5 As shown, the clamping plate 60 on the left positioning adjustment unit is used as an example for explanation. A receiving groove 67 is provided on the side of the clamping plate 60 facing the arch rib segment 1. The fine-tuning component 64 is installed in the receiving groove 67. The fine-tuning component 64 is located in the receiving groove 67 when it is contracted, so that the fine-tuning component 64 will not protrude from the side of the clamping plate 60. Therefore, during the lowering process of the arch rib segment 1, the fine-tuning component 64 will not protrude from the side of the clamping plate 60, and the fine-tuning component 64 will not affect the lowering of the arch rib segment 1. During the lowering process, the fine-tuning component 64 is located in the receiving groove 67, and the receiving groove 67 protects the fine-tuning component 64, which can prevent the bottom of the arch rib segment 1 from hitting the fine-tuning component 64.

[0045] At the same time, before the arch rib segment 1 is lowered between the clamping plate 60 of the left positioning adjustment unit and the clamping plate 60 of the right positioning adjustment unit, and before the bottom of the arch rib segment 1 contacts the top of the arch rib assembly frame 3, the fine-tuning components 64 on the two clamping plates 60 of the left positioning adjustment unit and the right positioning adjustment unit are extended from the receiving groove 67, and the fine-tuning components 64 on the two clamping plates 60 are extended at the same time, and gradually abut the left and right sides of the arch rib segment 1, and the fine-tuning components 64 on the two clamping plates 60 push the arch rib segment 1 to Figure 3 Push the arch rib segment 1 to the middle position of the two arch rib assembly frames 3 so that the arch rib segment 1 can be placed in the center (the center line of the arch rib segment 1 coincides with the center line between the two arch rib assembly frames 3), and then completely lower the arch rib segment 1 to the top of the arch rib assembly frame 3.

[0046] Therefore, through the scheme of this embodiment, the fine-tuning component 64 has two functions. On the one hand, the fine-tuning component 64 plays a role in accurately adjusting the position of the arch rib segment 1 during the lowering process, so that the position of the arch rib segment 1 lowered to the arch rib assembly frame 3 is more accurate; on the other hand, when the arch rib segment 1 is lowered, the fine-tuning component 64 clamps and fixes the arch rib segment 1.

[0047] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
