Description

Technical Field

[0001] The present invention belongs to the technical field of offshore highway bridge construction, and in particular relates to a method for moving pier-side outriggers based on the coordinated work of a shift trolley and a transport trolley. Background Art

[0002] Mobile formwork equipment is used in the construction of offshore highway bridges. This advanced construction technology is used for cast-in-place concrete bridge superstructures (primarily box girders). Its operating principle is to utilize the piers and abutments as support points, with the formwork's main longitudinal beams supporting the crossbeams, formwork, beam weight, and various construction loads. Essentially, it is a large steel support system with its own formwork that can be moved on the piers. After a section of bridge is cast, the formwork needs to be moved to the next construction location. This requires a specialized transfer trolley to move the formwork's main longitudinal beams. After completing construction at one station, the transfer trolley needs to be transported to the next station to ensure reuse. Furthermore, the supporting foundation (called pier support legs) beneath the transfer trolley needs to be moved to the next supporting pier to be constructed. Therefore, efficiently moving the pier support legs to the next station remains a technical challenge. Summary of the Invention

[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention are further described below with reference to specific embodiments.

[0035] The present invention designs a pier-side outrigger transport method based on the coordinated work of a shift trolley and a transport trolley. The method is achieved by the coordinated work of the shift trolley and the transport trolley.

[0036] The shift trolley 100 is shown in FIG. Figure 1 and attached Figure 2 , including a trolley base 1, an upper rotating seat 2, a sliding seat 3, an upper hooking mechanism 4, a lower hooking mechanism 5, a longitudinal driving mechanism 6, a transverse driving mechanism 7, a vertical adjustment support leg 8 and an upper hooking walking mechanism 9. See attached Figure 7 and attached Figure 8 When in use, the shift trolley 100 is set on the pier-side support leg 300, and the lower hook mechanism 5 of the shift trolley 100 is hooked with the top flange 301 of the pier-side support leg 300; the main longitudinal beam 200 of the formwork is set above the shift trolley 100 (the upper part of the main longitudinal beam 200 of the formwork supports the cross beam 600, and the upper part of the cross beam 600 supports the template 700, and the template 700 is used to cast the box beam 800 of the bridge body), and the upper hook mechanism 4 of the shift trolley 100 is hooked with the bottom flange 201 of the main longitudinal beam 200 of the formwork. Specifically, there are two main longitudinal beams 200 of the formwork, located on either side of the pier. A set of pier support legs 300 is provided on the front and rear sides of each pier. Each set of pier support legs 300 includes two symmetrically arranged pier support legs 300. Each pier support leg 300 has a vertical leg 302 at its base. The vertical legs 302 of adjacent pier support legs 300 are detachably connected by a connecting assembly 500. Furthermore, the tops of two adjacent pier support legs 300 are connected by a longitudinal beam 303, thereby stably connecting the four pier support legs 300 together and serving as a support base. When the pier support legs 300 need to be moved, the connecting assembly 500 and the longitudinal beam 303 are removed to disconnect the four pier support legs 300. Furthermore, it should be noted that the longitudinal beams 303 of the pier support legs 300 are also equipped with main support cylinders 400, which support the main longitudinal beams 200 of the formwork and adjust their height.

[0037] The specific structure of the shifting trolley 100 is described in detail below.

[0038] The trolley base 1 includes two main longitudinal beams 11, a middle main cross beam 12 and two end cross beams 13. The middle main cross beam 12 is connected to the middle position of the two main longitudinal beams 11, and the two end cross beams 13 are connected to the front and rear ends of the two main longitudinal beams 11.

[0039] The upper rotating seat 2 is rotatably mounted on the trolley base 1 via a vertical rotating shaft 21. Preferably, it is mounted on the central main beam 12 of the trolley base 1, and the vertical rotating shaft 21 is located at the center of the central main beam 12. The upper rotating seat 2 is elongated, and its lateral ends are arc-shaped. The lateral ends of the upper rotating seat 2 are mounted in the arc-shaped pressing seat 10, and the arc-shaped pressing seat 10 is fixed to the trolley base 1. The arc-shaped pressing seat 10 is used to fix the rotation angle of the upper rotating seat 2 around the vertical rotating shaft 21, that is, the rotation angle adjustment function of the upper rotating seat 2 is realized; for further explanation, see the attached Figure 3 The arc-shaped pressing seat 10 includes an arc-shaped base 101 and an arc-shaped pressure plate 102. The arc-shaped pressure plate 102 is installed on the arc-shaped base 101 through multiple bolts 103. The upper rotating seat 2 is pressed and fixed between the arc-shaped base 101 and the arc-shaped pressure plate 102. When the angle of the upper rotating seat 2 needs to be adjusted, loosen the bolts 103.

[0040] There are two slides 3, which are symmetrically mounted on the upper rotating seat 2, and the slides 3 are rotatably mounted on the upper rotating seat 2 via a transverse rotating shaft support mechanism 31. Furthermore, the transverse rotating shaft support mechanism 31 includes a transverse rotating shaft and a support seat. The support seat is fixed on the upper rotating seat 2, the transverse rotating shaft is mounted on the support seat, and the slide 3 is rotatably mounted on the transverse rotating shaft, so that the slide 3 can rotate around the rotating shaft. The slide 3 is used to support the main longitudinal beam of the mold frame. Since the slide 3 can rotate around the transverse rotating shaft, it can adapt to the pitch angle of the main longitudinal beam of the mold frame; and, as mentioned above, since the upper rotating seat 2 is rotatably mounted on the trolley base 1 via the vertical rotating shaft 21, it can also adapt to the deflection angle of the main longitudinal beam of the mold frame. Furthermore, the slide 3 is preferably a rectangular box structure, and a top plate 32 with a small friction coefficient is installed on its top surface, so that when the mold frame is moved, the friction between the main longitudinal beam of the mold frame and the slide 3 is reduced.

[0041] The upper hooking mechanism 4 is installed on the slide 3. There are two upper hooking mechanisms 4, which are respectively installed on the outer side walls of the two slides 3. The upper hooking mechanism 4 is arranged in the longitudinal direction and is used to hook on the bottom flange 201 of the main longitudinal beam 200 of the formwork (see the attached figure). Figure 7). Specifically, the upper hooking mechanism 4 includes a lifting cylinder 41, an upper hanger 42 and a guide column connecting assembly 43. The upper hanger 42 is installed on the outer wall of the slide 3 through two guide column connecting assemblies 43. The lifting cylinder 41 is located in the middle position between the two guide column connecting assemblies 43. The top end of the lifting cylinder 41 is connected to the upper hanger 42. The bottom end of the lifting cylinder 41 is hinged to the upper rotating seat 2. The upper hanger 42 is driven to rise and fall by the lifting cylinder 41. Furthermore, the guide column connecting assembly 43 includes a guide column 431 and a guide sleeve 432. The guide sleeve 432 is fixed on the slide 3. The guide column 431 is slidably installed in the guide sleeve 432, and the top end of the guide column 431 is fixedly connected to the upper hanger 42, thereby realizing that the upper hanger 42 can slide up and down relative to the slide 3. Furthermore, a limiting push rod 4311 is provided at the bottom of the guide column 431 (see attached Figure 2 ), when the lifting cylinder 41 contracts and lifts the trolley base 1 (this state is to make the mold frame shift trolley move along the main longitudinal beam of the mold frame, which will be described in detail below), the limiting push rods 4311 on both sides of the lifting cylinder 41 touch the top surface of the arc-shaped pressing seat 10, thereby making the trolley base 1 parallel to the upper hanger 42.

[0042] The upper hook walking mechanism 9 is arranged on the upper hanging frame 42 of the upper hook mechanism 4. The upper hook walking mechanism 9 includes a walking wheel 91 and a walking wheel driving module. The walking wheel 91 is installed on the upper hanging frame 42. The walking wheel driving module is rotatably connected with the walking wheel 91 to drive the walking wheel 91 to operate. Preferably, two sets of walking wheels 91 and walking wheel driving modules are arranged on each upper hanging frame 42. In the walking state, see the attached Figure 4 and attached Figure 5 The walking wheel 91 is suspended and supported on the track 202 of the bottom flange 201 of the main longitudinal beam 200 of the formwork (that is, the bottom side wall of the main longitudinal beam of the formwork is provided with a protruding flange, and the track is installed on the flange), and the lower hook mechanism 5 of the shifting trolley is disconnected from the pier support leg, the jacking cylinder 41 contracts, and the trolley base 1 is lifted. After the trolley base 1 is lifted into place, the bottom ends of the limiting push rods 4311 on both sides of the jacking cylinder 41 touch the top surface of the arc-shaped pressing seat 10, so that the trolley base 1 is parallel to the upper hanging frame 42; then the walking wheel driving module drives the walking wheel 91 to operate, thereby realizing the movement of the entire shifting trolley along the main longitudinal beam of the formwork to the pier support leg of the pier of the next construction station. Furthermore, the walking wheel driving module includes a driving motor 92 and a gear transmission assembly 93. The driving motor 92 is installed on the upper hanging frame 42, and the driving motor 92 drives the walking wheel 91 to operate through the gear transmission assembly 93.

[0043] The lower hooking mechanism 5 is arranged at the bottom of the trolley base 1, and the lower hooking mechanism 5 is arranged in the transverse direction for hooking with the top flange 301 of the pier support leg 300 (see the attached Figure 7Specifically, there are 4 groups of lower hooking mechanisms 5, which are respectively arranged at the front and rear sides of the bottom of the two main longitudinal beams 11 of the trolley base 1. Each group of lower hooking mechanisms 5 includes a pair of parallel and symmetrical transverse hook frames; see the attached Figure 6 The structure of the transverse hook frame is as follows: it includes a vertical plate 51 and a flat plate 52 connected to the inner side wall of the middle part of the vertical plate (the flat plate can be understood as a hook plate). A hooking space is formed between the flat plate 52 and the bottom surface of the trolley base 1. The hooking space is used to accommodate the top flange of the pier side support leg, that is, to achieve a hook connection; in order to ensure the strength of the flat plate 52, a reinforcing rib 53 is provided between the bottom surface of the flat plate 52 and the side wall of the vertical plate; furthermore, the lower hooking mechanism 5 is detachably mounted on the bottom of the trolley base 1 by bolts: that is, a plurality of groups of upper and lower corresponding bolt holes 54 are provided on the flat plate 52 and the bottom surface of the trolley base 1, so that the lower hooking mechanism 5 can be detachably mounted on the bottom of the trolley base 1 by bolts. The lower hooking mechanism 5 is detachably mounted on the bottom of the trolley base 1 by bolts so that it can be disconnected from the top flange of the pier side support leg when the pier side support leg is unloaded.

[0044] The longitudinal drive mechanism 6 is provided on the upper rotating seat 2 and is used to drive the main longitudinal beam of the mold frame to move. Specifically, the longitudinal drive mechanism 6 includes a longitudinal drive cylinder 61 and a detachable connecting seat 62. The tail end of the longitudinal drive cylinder 61 is hinged on the upper rotating seat 2, and the detachable connecting seat 62 is connected to the front end of the longitudinal drive cylinder 61. The detachable connecting seat 62 is used to be detachably connected to the main longitudinal beam of the mold frame, so that the longitudinal drive cylinder 61 can move the main longitudinal beam of the mold frame in a step-by-step manner. Specifically, a transverse pin hole 621 is provided on the detachable connecting seat 62 (see FIG. Figure 1 ), correspondingly, the bottom of the main longitudinal beam of the mold frame is also provided with plug holes arranged at intervals along the longitudinal direction. When moving, the main longitudinal beam of the mold frame is supported by the slide 3 (ie, see the attached Figure 7 , the main support cylinder 400 contracts to lower the main longitudinal beam of the mold frame, so that the main longitudinal beam of the mold frame is supported by the slide 3). First, the detachable connecting seat 62 is connected to the bottom plug-in hole of the mold frame main longitudinal beam through a pin, and then the longitudinal driving cylinder 61 is activated to achieve one-step movement. Then, the pin is pulled out to disconnect the detachable connecting seat 62 from the main longitudinal beam of the mold frame, and the longitudinal driving cylinder 61 is reset. After resetting, the detachable connecting seat 62 is reconnected to the bottom plug-in hole of the main longitudinal beam of the mold frame through the pin, and the longitudinal driving cylinder 61 is activated again to achieve the next step of movement. Repeat the above operations to achieve step-by-step movement of the main longitudinal beam of the mold frame by the longitudinal driving cylinder 61.

[0045] The transverse driving mechanism 7 is arranged on the front and rear sides of the trolley base 1. The transverse driving mechanism 7 is arranged horizontally to realize the transverse relative movement between the shifting trolley and the pier-side support leg. Specifically, the transverse driving mechanism 7 includes a transverse driving cylinder 71 and a detachable connecting plate 72. The tail end of the transverse driving cylinder 71 is hinged on the trolley base 1, and the detachable connecting plate 72 is connected to the front end of the transverse driving cylinder 71. The detachable connecting plate 72 is used to be detachably connected to the pier-side support leg (specifically, a vertical pin hole is provided on the detachable connecting plate 72, and plug holes arranged at intervals along the transverse direction are provided on the top flange of the pier-side support leg. The detachable connection between the detachable connecting plate 72 and the top flange of the pier-side support leg is realized by a pin), thereby realizing the step-by-step transverse movement between the shifting trolley and the pier-side support leg.

[0046] The lateral relative movement between the shift trolley and the pier support legs means that: when the pier support legs are fixed, the lateral driving mechanism 7 is actuated to drive the shift trolley to move laterally along the top flange of the pier support legs; and when the pier support legs are unlocked (i.e., the four pier support legs 300 are disconnected) and lifted by the shift trolley (i.e., the upper hook mechanism 4 of the shift trolley is hooked on the main longitudinal beam of the formwork, and then the lifting cylinder 41 contracts to lift the shift trolley, since the lower hook mechanism 5 of the shift trolley is hooked and connected to the pier support legs, Therefore, the rising of the shift trolley will lift the pier side support leg and make it off the ground; in addition, it should be noted that in order to ensure the stability of the shift trolley hooked on the main longitudinal beam of the formwork, a limit seat is embedded on the outer side of the walking wheel 91 to prevent the shift trolley from slipping due to the large inclination angle of the main longitudinal beam of the formwork). Then the transverse driving mechanism 7 will drive the pier side support leg to move laterally along the lower hooking mechanism 5 (during this movement, the main longitudinal beam of the formwork serves as a fixed foundation), thereby realizing the lateral outward movement of the pier side support leg, which is convenient for the subsequent movement of the pier side support leg.

[0047] The vertically adjustable support legs 8 are mounted on the trolley base 1 to support the main longitudinal beams of the formwork. There are four vertically adjustable support legs 8, located at the four corners of the trolley base 1. The height of the vertically adjustable support legs 8 is adjustable to accommodate and adjust the pitch angle of the main longitudinal beams of the formwork.

[0048] The transport trolley 900 is mounted on the track on the outer side wall of the main longitudinal beam 200 of the formwork and can move along the main longitudinal beam 200 of the formwork. Figure 9 , specifically describe the structure of the transport trolley 900.

[0049] The transport trolley 900 includes an inner frame 901 , an outer bracket 902 and a bottom rotating hanger 903 .

[0050] The inner frame 901 is a vertically arranged rectangular frame structure, and a top guide wheel 9011 is provided on the top thereof for cooperating with the upper track 203 on the outer side wall of the main longitudinal beam 200 of the mold frame (see attached Figure 7 Specifically, the top guide wheel 9011 contacts the inner side of the upper track 203, thereby preventing the top of the transport trolley 900 from falling outward from the upper track 203; a longitudinal arm 9012 is fixedly connected to the middle of the inner frame 901, and two sets of motor-driven running wheel mechanisms 9013 are provided on the longitudinal arm 9012. The running wheel mechanisms 9013 are used to cooperate with the lower track 204 on the outer side wall of the main longitudinal beam 200 of the mold frame (see attached Figure 7 ), the transport trolley 900 is driven by the walking wheel mechanism 9013 to move along the main longitudinal beam 200 of the formwork; a middle guide wheel 9014 is also provided in the middle of the inner frame 901, and the middle guide wheel 9014 contacts the outer wall of the lower track 204; under the joint action of the above-mentioned top guide wheel 9011, the walking wheel mechanism 9013 and the middle guide wheel 9014, the inner frame 901 is stably installed on the outer wall of the main longitudinal beam 200 of the formwork, and has the ability to actively move.

[0051] The outer bracket 902 is located outside the inner frame 901 and is installed on the inner frame 901 through an upper sliding sleeve 9021 and a lower sliding sleeve 9022. A vertical cylinder 904 is provided between the outer bracket 902 and the inner frame 901 to drive the outer bracket 902 to move up and down.

[0052] The bottom rotating hanger 903 is mounted on the lower portion of the outer bracket 902 via a slewing support structure. A rotary drive cylinder 905 is provided at the bottom of the outer bracket 902. The actuating end of the rotary drive cylinder 905 is connected to the vertical rotation shaft 9023 of the bottom rotating hanger 903 via a connecting arm, thereby driving the rotation of the bottom rotating hanger 903 via the rotary drive cylinder 905. A bottom hooking mechanism 9031 is provided on the bottom surface of the bottom rotating hanger 903 for hooking with the top flange 301 of the pier support leg 300. The structure of the bottom hooking mechanism 9031 is identical to the lower hooking mechanism 5 of the shifting trolley and will not be further described here.

[0053] See the attached Figure 10 -Attached Figure 12 , describing a method for moving pier-side legs based on the shift trolley and the transport trolley.

[0054] Step 1: The main supporting cylinders 400 on the pier support legs 300 at the two adjacent pier positions provide stable support for the formwork main longitudinal beam 200; the front end of the front outrigger 206 of the formwork main longitudinal beam 200 is fixedly supported on the next pier on the front side through the front door frame 2061, and the rear end of the rear outrigger 207 of the formwork main longitudinal beam 200 is fixedly suspended on the cast box beam of the previous pier on the rear side through the rear hanger 2071; the shifting trolley 100 at the front pier position of the two adjacent piers is moved along the front outrigger 206 to the next pier position on the front side (see attached Figure 12 ), the lower hook mechanism 5 at the bottom of the shift trolley 100 needs to be removed before it moves.

[0055] Step 2: Disconnect the four pier-side support legs 300 at the upper pier on the rear side. The lower hook mechanism 5 of the shift trolley and the pier-side support legs 300 are now in a hook-connected state. Then the lifting cylinder 41 of the upper hook mechanism 4 of the shift trolley 100 contracts to lift the trolley base 1 and the pier-side support legs 300 together, so that the pier-side support legs 300 are off the ground (the ground here refers to the pier surface), and the limiting push rods 4311 on both sides of the lifting cylinder 41 touch the top surface of the arc-shaped clamping seat 10, so that the trolley base 1 is parallel to the upper hanger 42, that is, the trolley base 1 is parallel to the main longitudinal beam 200 of the formwork.

[0056] Step 3: Move the transport trolley 900 to the outside of one of the pier support legs 300 of the upper pier on the rear side, and adjust the upper and lower positions of the outer bracket 902 through the vertical cylinder 904 so that the bottom hook mechanism 9031 of the bottom rotating hanger 903 is directly opposite to the top flange 301 of the pier support leg 300 (since the trolley base 1 is already parallel to the main longitudinal beam 200 of the formwork, and the running track of the transport trolley 900 is also parallel to the main longitudinal beam 200 of the formwork, the lower hook mechanism 5 of the trolley base 1 is also directly opposite to the bottom hook mechanism 9031 of the bottom rotating hanger 903, that is, the bottom hook mechanism 9031 of the bottom rotating hanger 903 is directly opposite to the top flange 301 of the pier support leg 300).

[0057] Step 4: Then the lateral drive mechanism 7 of the shift trolley 100 is activated to drive the pier support leg to move laterally outward along the lower hook mechanism 5, so that the top flange 301 of the pier support leg 300 is inserted into the bottom hook mechanism 9031 of the bottom rotating hanger 903 of the transport trolley 900 (see attached Figure 10 ), after being inserted into the set distance, the lower hook mechanism 5 of the shift trolley is disassembled, and then the bottom rotating hanger 903 of the transport trolley 900 is rotated 90 degrees (see the attached Figure 11), placing the pier support leg 300 in a longitudinal position. The transport trolley 900 then moves along the track to the next pier position in front, where its bottom rotating hanger 903 rotates 90 degrees, placing the pier support leg 300 in a horizontal position. The lower hook mechanism 5 of the transfer trolley 100 at this pier position is then reinstalled (in step 1, the transfer trolley 100 has already been moved to this pier position and the lower hook mechanism 5 removed from its bottom), so that the top flange 301 of the pier support leg 300 is hooked and connected to the lower hook mechanism 5 of the transfer trolley 100. The transverse drive mechanism 7 of the transfer trolley 100 then operates, driving the pier support leg to move laterally inward along the lower hook mechanism 5 to the designated position, thus completing the transfer of one pier support leg 300. Next, following the above operations, the remaining three pier support legs 300 at the previous pier on the rear side are similarly transferred to the next pier position in front, and the four pier support legs are then assembled and connected.

[0058] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0059] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.

[0060] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other skilled in the art without expending creative labor falls within the scope of protection of the present invention.
