Description

TECHNICAL FIELD

[0001] The present application belongs to the offshore highway bridge construction technical field, and particularly relates to a displacement trolley for offshore highway bridge construction. BACKGROUND

[0002] When an offshore highway bridge is being built, a movable formwork device is used, which is an advanced construction technology for cast-in-situ concrete bridge superstructure (mainly box girder). Its working principle is to use the pier and pile cap as the support point, and support the cross beam, formwork, beam weight and various construction loads through the main longitudinal beam of the formwork. It is essentially a large steel support system with formwork that can move on the pier by itself, that is, after the pouring construction of a section of the bridge is completed, the formwork needs to be moved to the next construction position, so a special displacement trolley is needed to drive the formwork main longitudinal beam to move.

[0003] The existing displacement trolley usually only has the function of moving the formwork longitudinally, and the function is simple, which cannot meet the needs of multi-dimensional adjustment of the formwork. Moreover, after the displacement trolley completes the construction of the current work station, it needs to be transported to the next work station to realize the reuse of the trolley. How to efficiently transport the displacement trolley to the next work station is also a technical problem to be solved. SUMMARY

[0004] The purpose of the present application is to overcome the shortcomings of the prior art and provide a displacement trolley for offshore highway bridge construction. The displacement trolley can realize driving the formwork to step longitudinally, adjusting the pitch angle of the formwork, adjusting the deflection angle of the formwork, adjusting the lateral movement of the formwork, and suspending the whole displacement trolley on the formwork and walking along the longitudinal direction of the formwork, so as to move the displacement trolley to the next construction position, and also realize the lifting and lateral movement of the pier-side support leg below.

[0005] The present application is realized by the following technical solutions:

[0014] In the above technical scheme, a vertical pin hole is arranged on the detachable connecting plate of the transverse moving driving mechanism; a plurality of transversely spaced plug-in holes are arranged on the top flange of the pier-side supporting leg; and the detachable connecting plate and the top flange of the pier-side supporting leg are detachably connected through a plug pin.

[0015] In the above technical scheme, the transverse moving driving mechanism is arranged on the front and rear sides of the trolley base, and comprises a transverse moving driving oil cylinder and a detachable connecting plate; the tail end of the transverse moving driving oil cylinder is hinged on the trolley base; and the detachable connecting plate is connected with the front end of the transverse moving driving oil cylinder, which is used for detachable connection with the top flange of the pier-side supporting leg.

The central main crossbeam is connected to the middle of the two main longitudinal beams, and the two end crossbeams are connected to the front and rear ends of the two main longitudinal beams.

[0017] In the above technical solution, the upper rotating seat is elongated, and its two horizontal ends are arc-shaped.

[0018] In the above technical solution, the guide column connecting assembly includes a guide column and a guide sleeve. The guide sleeve is fixed on the slide block, the guide column is slidably installed inside the guide sleeve, and the top end of the guide column is fixedly connected to the upper bracket. A limit rod is provided at the bottom of the guide column.

The structure of the transverse hooks includes a vertical plate and a flat plate connected to the inner side wall of the middle of the vertical plate. A hooking space is formed between the flat plate and the bottom surface of the trolley base, which is used to accommodate the top flange of the pier support leg.

[0033] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0034] A type of moving trolley for the construction of offshore highway bridges, see attached document. Figure 1 and attached Figure 2 It includes a trolley base 1, an upper rotating seat 2, a sliding seat 3, an upper hook mechanism 4, a lower hook mechanism 5, a longitudinal drive mechanism 6, a transverse drive mechanism 7, a vertical adjustable support leg 8, and an upper hook walking mechanism 9.

[0035] See appendix Figure 7 and attached Figure 8 In use, the shifting trolley 100 of the present invention is set on the pier-side support leg 300, and the lower hooking mechanism 5 of the shifting trolley 100 is hooked to the top flange 301 of the pier-side support leg 300; a main longitudinal beam 200 of the formwork frame is set above the shifting trolley 100 (the upper part of the main longitudinal beam 200 of the formwork frame supports the cross beam 600, the upper part of the cross beam 600 supports the template 700, and the template 700 is used to cast the box girder 800 of the bridge body), and the upper hooking mechanism 4 of the shifting trolley 100 is hooked to the bottom flange 201 of the main longitudinal beam 200 of the formwork frame. Furthermore, the main longitudinal beams 200 of the formwork frame consist of two beams located on either side of the pier. A set of pier-side support legs 300 is installed on both the front and rear sides of each pier. Each set of pier-side support legs 300 includes two symmetrically arranged pier-side support legs 300. Each pier-side support leg 300 has a vertical leg 302 at its bottom. The vertical legs 302 of adjacent pier-side support legs 300 are detachably connected by a screw assembly 500. The tops of two adjacent pier-side support legs 300 are connected by a longitudinal beam 303, thus stably connecting the four pier-side support legs 300 together as a support foundation. When it is necessary to move the pier-side support legs 300, the screw assembly 500 and the longitudinal beam 303 can be disassembled to separate the four pier-side support legs 300. In addition, it should be noted that the pier-side support legs 300 are also equipped with main support cylinders 400, which support the main longitudinal beams 200 of the formwork frame and allow for height adjustment.

[0036] The specific structure of the transfer trolley 100 of the present invention will be described in detail below.

[0037] The trolley base 1 includes two main longitudinal beams 11, a central main crossbeam 12, and two end crossbeams 13. The central main crossbeam 12 is connected to the middle of the two main longitudinal beams 11, and the two end crossbeams 13 are connected to the front and rear ends of the two main longitudinal beams 11.

[0038] 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 crossbeam 12 of the trolley base 1, with the vertical rotating shaft 21 located at the center of the central main crossbeam 12. The upper rotating seat 2 is elongated with arc-shaped ends. The horizontal ends of the upper rotating seat 2 are mounted in arc-shaped clamping seats 10, which are fixed to the trolley base 1. The arc-shaped clamping seats 10 fix the rotation angle of the upper rotating seat 2 around the vertical rotating shaft 21, thus realizing the rotation angle adjustment function of the upper rotating seat 2. Further details can be found in the appendix. Figure 3 The arc-shaped clamping 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 by multiple bolts 103. The upper rotating seat 2 is clamped and fixed between the arc-shaped base 101 and the arc-shaped pressure plate 102. When it is necessary to adjust the angle of the upper rotating seat 2, the bolts 103 are loosened.

[0039] Two slide blocks 3 are symmetrically mounted on the upper rotating seat 2, and the slide blocks 3 are rotatably mounted on the upper rotating seat 2 via a transverse rotating shaft support mechanism 31. Further, the transverse rotating shaft support mechanism 31 includes a transverse rotating shaft and a support base. The support base is fixed to the upper rotating seat 2, the transverse rotating shaft is mounted on the support base, and the slide blocks 3 are rotatably mounted on the transverse rotating shaft, thereby enabling the slide blocks 3 to rotate around this rotating shaft. The slide blocks 3 are used to support the main longitudinal beam of the mold frame. Since the slide blocks 3 can rotate around the transverse rotating shaft, they 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 a vertical rotating shaft 21, it can also adapt to the deflection angle of the main longitudinal beam of the mold frame. Further, the slide blocks 3 are preferably rectangular box structures, with a top plate 32 of low friction coefficient mounted on its top surface, thereby reducing the friction between the main longitudinal beam of the mold frame and the slide blocks 3 when the mold frame is moved.

[0040] The upper hooking mechanism 4 is mounted on the slide block 3. There are two upper hooking mechanisms 4, which are respectively mounted on the outer side walls of the two slide blocks 3. The upper hooking mechanisms 4 are arranged longitudinally and are used to hook onto the bottom flange 201 of the main longitudinal beam 200 of the mold frame (see Appendix). Figure 7Specifically, the upper hook mechanism 4 includes a lifting cylinder 41, an upper hanger 42, and a guide column connecting assembly 43. The upper hanger 42 is mounted on the outer wall of the slide block 3 via two guide column connecting assemblies 43. The lifting cylinder 41 is located in the middle between the two guide column connecting assemblies 43. The top end of the lifting cylinder 41 is connected to the upper hanger 42, and the bottom end of the lifting cylinder 41 is hinged to the upper rotating seat 2. The lifting cylinder 41 drives the upper hanger 42 to rise and fall. Further, the guide column connecting assembly 43 includes a guide column 431 and a guide sleeve 432. The guide sleeve 432 is fixed to the slide block 3, and the guide column 431 is slidably installed inside the guide sleeve 432. The top end of the guide column 431 is fixedly connected to the upper hanger 42, thereby allowing the upper hanger 42 to slide up and down relative to the slide block 3. Further, a limit rod 4311 is provided at the bottom of the guide column 431 (see Appendix). Figure 2 When the lifting cylinder 41 retracts and lifts the trolley base 1 (this state is to allow the mold frame displacement trolley to travel along the main longitudinal beam of the mold frame, which will be described in detail below), the limiting rods 4311 on both sides of the lifting cylinder 41 touch the top surface of the arc-shaped clamping seat 10, thereby making the trolley base 1 parallel to the upper hanging frame 42.

[0041] The upper hook-and-walk mechanism 9 is mounted on the upper bracket 42 of the upper hook-and-walk mechanism 4. The upper hook-and-walk mechanism 9 includes a walking wheel 91 and a walking wheel drive module. The walking wheel 91 is mounted on the upper bracket 42, and the walking wheel drive module is rotatably connected to the walking wheel 91 to drive its rotation. Preferably, each upper bracket 42 has two sets of walking wheels 91 and walking wheel drive modules. In the walking state, see the attached diagram. Figure 4 and attached Figure 5 The traveling wheels 91 are suspended and supported on the rails 202 of the bottom flange 201 of the main longitudinal beam 200 of the formwork frame (i.e., the bottom side wall of the main longitudinal beam of the formwork frame has a protruding flange, and the rails are installed on the flanges). The lower hook mechanism 5 of the moving trolley is disconnected from the pier-side support leg, the lifting cylinder 41 retracts, and the trolley base 1 is lifted. After the trolley base 1 is lifted into place, the bottom ends of the limiting rods 4311 on both sides of the lifting cylinder 41 touch the top surface of the arc-shaped pressing seat 10, so that the trolley base 1 is parallel to the upper bracket 42. Then the traveling wheel drive module drives the traveling wheels 91 to rotate, thereby realizing the movement of the entire moving trolley along the main longitudinal beam of the formwork frame, moving to the pier-side support leg of the next construction position. Further, the traveling wheel drive module includes a drive motor 92 and a gear transmission assembly 93. The drive motor 92 is installed on the upper bracket 42, and the drive motor 92 drives the traveling wheels 91 to rotate through the gear transmission assembly 93.

[0042] The lower hooking mechanism 5 is located at the bottom of the trolley base 1. The lower hooking mechanism 5 is arranged laterally and is used to hook onto the top flange 301 of the support leg 300 beside the pier (see Appendix). Figure 7Specifically, there are four sets of lower hooking mechanisms 5, arranged on the front and rear sides of the bottom of the two main longitudinal beams 11 of the trolley base 1. Each set of lower hooking mechanisms 5 includes a pair of parallel and symmetrically arranged transverse hooks; see appendix. Figure 6 The structure of the transverse hook frame includes an upright plate 51 and a flat plate 52 (which can be understood as a hook plate) connected to the inner side wall of the upright plate. A hooking space is formed between the flat plate 52 and the bottom surface of the trolley base 1. This hooking space is used to accommodate the top flange of the pier support leg, thus achieving a hook connection. 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 upright plate. Furthermore, the lower hooking mechanism 5 is detachably installed at the bottom of the trolley base 1 by bolts: that is, multiple sets of corresponding bolt holes 54 are provided on the bottom surfaces of the flat plate 52 and the trolley base 1, so that the lower hooking mechanism 5 can be detachably installed at the bottom of the trolley base 1 by bolts. The lower hooking mechanism 5 is detachably installed at the bottom of the trolley base 1 by bolts so that it can be disconnected from the top flange of the pier support leg when transporting it.

[0043] The longitudinal movement drive mechanism 6 is mounted on the upper rotating seat 2 and is used to drive the main longitudinal beam of the mold frame to move. Specifically, the longitudinal movement drive mechanism 6 includes a longitudinal movement drive cylinder 61 and a detachable connecting seat 62. The tail end of the longitudinal movement drive cylinder 61 is hinged to the upper rotating seat 2, and the detachable connecting seat 62 is connected to the front end of the longitudinal movement drive cylinder 61. The detachable connecting seat 62 is used for detachable connection with the main longitudinal beam of the mold frame, thereby realizing the step-by-step movement of the main longitudinal beam of the mold frame by the longitudinal movement drive cylinder 61. Specifically, the detachable connecting seat 62 is provided with a transverse pin hole 621 (see...). Figure 1 Correspondingly, insertion holes are also provided at longitudinal intervals at the bottom of the main longitudinal beam of the mold frame. During movement, the sliding block 3 supports the main longitudinal beam of the mold frame (i.e., see Appendix). Figure 7 The main support cylinder 400 retracts, causing the main longitudinal beam of the mold frame to descend, thus enabling the slide block 3 to support the main longitudinal beam of the mold frame. First, the detachable connecting seat 62 is connected to the bottom insertion hole of the main longitudinal beam of the mold frame through a pin. Then, the longitudinal movement drive cylinder 61 moves to achieve one-step movement. Then, the pin is pulled out to disconnect the connection between the detachable connecting seat 62 and the main longitudinal beam of the mold frame, and the longitudinal movement drive cylinder 61 is reset. After resetting, the detachable connecting seat 62 is reconnected to the bottom insertion hole of the main longitudinal beam of the mold frame through a pin, and the longitudinal movement drive cylinder 61 moves again to achieve the next step of movement. The above operation is repeated to achieve step-by-step movement of the main longitudinal beam of the mold frame by the longitudinal movement drive cylinder 61.

[0044] The lateral movement drive mechanism 7 is located on the front and rear sides of the trolley base 1. The lateral movement drive mechanism 7 is horizontally positioned to realize the lateral relative movement between the moving trolley and the pier-side support leg. Specifically, the lateral movement drive mechanism 7 includes a lateral movement drive cylinder 71 and a detachable connecting plate 72. The tail end of the lateral movement drive cylinder 71 is hinged to the trolley base 1, and the detachable connecting plate 72 is connected to the front end of the lateral movement drive cylinder 71. This detachable connecting plate 72 is used for detachable connection with the pier-side support leg (specifically, the detachable connecting plate 72 has vertical pin holes, and the top flange of the pier-side support leg has horizontally spaced insertion holes; the detachable connection between the detachable connecting plate 72 and the top flange of the pier-side support leg is achieved through pins), thereby realizing the step-by-step lateral movement between the moving trolley and the pier-side support leg.

[0045] Furthermore, the lateral relative movement between the shifting trolley and the pier-side support leg refers to the following: when the pier-side support leg is fixed, the lateral movement drive mechanism 7 will drive the shifting trolley to move laterally along the top flange of the pier-side support leg; and when the pier-side support leg is unlocked and lifted by the shifting trolley (i.e., the upper hooking mechanism 4 of the shifting trolley hooks onto the main longitudinal beam of the formwork, and then the lifting cylinder 41 retracts, causing the shifting trolley to rise), since the lower hooking mechanism 5 of the shifting trolley is hooked to the pier-side support leg, the shifting trolley... The lifting process will hoist the pier-side support leg off the ground. In addition, it should be noted that in order to ensure the stability of the shifting trolley hooked on the main longitudinal beam of the formwork, a limiting seat is embedded on the outside of the traveling wheel 91 to prevent the shifting trolley from slipping due to the large tilt angle of the main longitudinal beam of the formwork. The action of the lateral drive 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 facilitates the subsequent relocation of the pier-side support leg.

[0046] The vertical adjustable support legs 8 are mounted on the trolley base 1 and are used to support the main longitudinal beam of the mold frame. There are four vertical adjustable support legs 8, which are respectively located at the four corners of the trolley base 1. The height of the vertical adjustable support legs 8 is adjustable, which can adapt to and adjust the pitch angle of the main longitudinal beam of the mold frame.

[0047] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations 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 figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0048] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0049] The present invention has been described above by way of example. It should be noted that any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort without departing from the core of the present invention fall within the protection scope of the present invention.

10. The moving trolley for constructing marine highway bridges according to claim 1, characterized in that: The detachable connecting seat of the longitudinal drive mechanism is provided with transverse pin holes. Correspondingly, the bottom of the main longitudinal beam of the mold frame is also provided with insertion holes arranged longitudinally at intervals. During movement, the detachable connecting seat is first connected to the insertion hole at the bottom of the main longitudinal beam of the mold frame through a pin. Then, the longitudinal drive cylinder is activated to achieve one step of movement. Then, the pin is pulled out to disconnect the connection between the detachable connecting seat and the main longitudinal beam of the mold frame, and the longitudinal drive cylinder is reset. After resetting, the detachable connecting seat is reconnected to the insertion hole at the bottom of the main longitudinal beam of the mold frame through a pin. The longitudinal drive cylinder is activated again to achieve the next step of movement. This process is repeated to achieve step-by-step movement of the main longitudinal beam of the mold frame by the longitudinal drive cylinder.
