Description

Technical Field

[0001] The invention belongs to the technical field of offshore highway bridge construction, and particularly relates to a traveling method of a formwork shifting 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 caps 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. That is, after a section of bridge construction is completed, the formwork needs to be moved to the next construction location. Therefore, a specialized formwork shifting trolley is required to drive the formwork's main longitudinal beams for movement.

[0003] Existing mold frame shifting trolleys typically only have the function of moving the mold frame longitudinally. This simple function cannot meet the needs of multi-dimensional mold frame adjustment. Moreover, after completing the construction of the current workstation, the mold frame shifting trolley needs to be transported to the next workstation to achieve reuse. How to efficiently transport the mold frame shifting trolley to the next workstation is also a technical problem that needs to be solved. Summary of the Invention

[0026] 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.

[0027] A walking method for the mold frame shifting trolley, see the attached Figure 1 and attached Figure 2 The mold frame shifting trolley includes a trolley base 1, an upper rotating seat 2, a slide 3, an upper hooking mechanism 4, a longitudinal driving mechanism 6 and an upper hooking walking mechanism 9.

[0028] See attached Figure 6 and attached Figure 7When in use, the formwork shifting trolley 100 of the present invention is set on the pier support leg 300. The formwork shifting trolley 100 is connected to the top flange 301 of the pier support leg 300 through a lower detachable connecting plate. The formwork main longitudinal beam 200 is set above the formwork shifting trolley 100 (the upper part of the formwork main longitudinal beam 200 supports the crossbeam 600, and the upper part of the crossbeam 600 supports the formwork 700, which is used to cast the box beam 800 of the bridge body). The upper hooking mechanism 4 of the formwork shifting trolley 100 is hooked with the bottom flange 201 of the formwork main longitudinal beam 200. In addition, it should be noted that the pier support leg 300 is also provided with a main supporting cylinder 400, which supports the formwork main longitudinal beam 200 and can adjust the height of the formwork main longitudinal beam 200. Furthermore, there are two main longitudinal beams 200 of the formwork, which are located on both sides of the pier. A group of pier-side support legs 300 are respectively set on the front and rear sides of each pier, and each group of pier-side support legs 300 includes two symmetrically arranged pier-side support legs 300.

[0029] The specific structure of the mold frame shifting trolley 100 of the present invention is described in detail below.

[0030] 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.

[0031] 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.

[0032] There are two slides 3, which are symmetrically fixed 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.

[0033] 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 6 ). 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.

[0034] Four sets of lower detachable connecting plates 5 are provided at the bottom of the trolley base 1 for detachably connecting to the top flanges 301 of the pier support legs 300 .

[0035] 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 formwork is also provided with plug holes arranged at intervals along the longitudinal direction. When the formwork is moved, the trolley base 1 is fixedly connected to the pier support legs below it through the detachable connecting plate 5, and the main longitudinal beam of the formwork is supported by the slide 3 (i.e., see the attached Figure 6 , 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.

[0036] The upper hook walking mechanism 9 is arranged on the upper hanging bracket 42 of the upper hook mechanism 4, and 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 bracket 42, and the walking wheel driving module is rotatably connected to 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 set on each upper hanging bracket 42.

[0037] The moving method of the mold frame shifting trolley is as follows:

[0038] See attached Figure 4 and attached Figure 5The 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 detachable connecting plate 5 of the formwork shifting trolley is disconnected from the pier side support leg, and the jacking cylinder 41 contracts to lift the trolley base 1. 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 hanger 42; then the walking wheel driving module drives the walking wheel 91 to operate, thereby realizing the movement of the entire formwork shifting trolley along the main longitudinal beam of the formwork and moving it to the pier side support leg of the pier of the next construction station. Furthermore, the travel wheel drive module includes a drive motor 92 and a gear transmission assembly 93 . The drive motor 92 is mounted on the upper bracket 42 . The drive motor 92 drives the travel wheel 91 to operate through the gear transmission assembly 93 .

[0039] Furthermore, vertically adjustable support legs 8 are provided 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 adapt to and adjust the pitch angle of the main longitudinal beams of the formwork.

[0040] 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.

[0041] 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.

[0042] 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.
