Description

Technical Field

[0001] This utility model belongs to the field of marine highway bridge construction technology, specifically relating to a formwork shifting trolley device. Background Technology

[0002] Mobile formwork equipment is used in the construction of highway bridges over the sea. This advanced construction technology is employed for the superstructure of cast-in-place concrete bridges (primarily box girders). Its working principle involves using piers and abutments as support points, with the main longitudinal beams of the formwork supporting the crossbeams, formwork, beam weight, and various construction loads. Essentially, it is a large steel support system with its own formwork that can move independently on the piers. That is, after completing one section of bridge pouring, the formwork needs to be moved to the next construction location; therefore, a specialized formwork moving trolley is required to drive the main longitudinal beams of the formwork.

[0003] Existing formwork transfer trolleys typically only have the function of longitudinally moving the formwork, which is simple and cannot meet the needs of multi-dimensional adjustment of the formwork. Moreover, after completing the construction at the current workstation, the formwork transfer trolley needs to be transported to the next workstation to achieve the reuse of the trolley. How to efficiently transport the formwork transfer trolley to the next workstation is also a technical problem that needs to be solved. Utility Model Content

[0024] 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.

[0025] A mold frame shifting trolley device, see attached. 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 longitudinal drive mechanism 6, and an upper hook traveling mechanism 9.

[0026] See appendix Figure 6 and attached Figure 7In use, the formwork shifting trolley device 100 of this utility model is mounted on the pier-side support leg 300. The formwork shifting trolley device 100 is connected to the top flange 301 of the pier-side support leg 300 via a detachable lower connecting plate. A main longitudinal beam 200 is mounted above the formwork shifting trolley device 100 (the main longitudinal beam 200 supports a crossbeam 600, which in turn supports a template 700 used for casting the box girder 800 of the bridge body). The upper hooking mechanism 4 of the formwork shifting trolley device 100 is hooked to the bottom flange 201 of the main longitudinal beam 200. Furthermore, it should be noted that a main support cylinder 400 is also mounted on the pier-side support leg 300, which supports the main longitudinal beam 200 and allows for height adjustment. To elaborate further, there are two main longitudinal beams 200 of the formwork, located on both sides of the pier. Each pier has a set of pier-side support legs 300 on both the front and rear sides, and each set of pier-side support legs 300 includes two symmetrically arranged pier-side support legs 300.

[0027] The specific structure of the mold frame shifting trolley device 100 of this utility model is described in detail below.

[0028] 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.

[0029] 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 its horizontal ends being arc-shaped. The horizontal ends of the upper rotating seat 2 are mounted in arc-shaped pressure seats 10, which are fixed to the trolley base 1. Further details can be found in the appendix. Figure 3 The arc-shaped pressure seat 10 includes an arc-shaped base 101 and an arc-shaped pressure plate 102. The arc-shaped pressure plate 102 is mounted on the arc-shaped base 101 by multiple bolts 103. The end of the upper rotating seat 2 is mounted between the arc-shaped base 101 and the arc-shaped pressure plate 102.

[0030] Two slide blocks 3 are symmetrically fixedly 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 on 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.

[0031] 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 6 Specifically, 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 enabling 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 shifting trolley device 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 pressure seat 10, thereby making the trolley base 1 parallel to the upper hanging frame 42.

[0032] The bottom of the trolley base 1 is provided with 4 sets of detachable lower connecting plates 5, which are used to detachably connect with the top flange 301 of the pier support leg 300.

[0033] 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 formwork. When moving the formwork, the trolley base 1 is fixedly connected to the pier-side support leg below it through the detachable connecting plate 5, and the main longitudinal beam of the formwork is supported by the sliding seat 3 (i.e., see Appendix). Figure 6 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.

[0034] 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 the walking wheel 91 to rotate. Preferably, each upper bracket 42 is provided with two sets of walking wheels 91 and walking wheel drive modules.

[0035] The movement method of the mold frame shifting trolley device is as follows:

[0036] See appendix Figure 4 and attached Figure 5The traveling wheel 91 is suspended and supported on the track 202 of the bottom flange 201 of the main longitudinal beam 200 of the formwork frame (that is, the bottom side wall of the main longitudinal beam of the formwork frame has an outwardly protruding flange, and the track is installed on the flange). The lower detachable connecting plate 5 of the formwork frame shifting trolley device is disconnected from the pier-side support leg. The lifting cylinder 41 retracts, lifting the trolley base 1. 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 pressure seat 10, making the trolley base 1 parallel to the upper hanging frame 42. Then the traveling wheel drive module drives the traveling wheel 91 to rotate, thereby realizing the movement of the entire formwork frame shifting trolley device along the main longitudinal beam of the formwork frame, moving to the pier-side support leg of the bridge pier at the next construction position. Furthermore, the walking 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, and the drive motor 92 drives the walking wheel 91 to rotate through the gear transmission assembly 93.

[0037] Furthermore, vertically adjustable support legs 8 are also provided on the trolley base 1 to support the main longitudinal beam of the mold frame. There are four vertically adjustable support legs 8, which are respectively set at the four corners of the trolley base 1. The height of the vertically adjustable support legs 8 is adjustable, which can adapt to and adjust the pitch angle of the main longitudinal beam of the mold frame.

[0038] 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.

[0039] 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.

[0040] The present invention has been described above by way of example. It should be noted that, without departing from the core of the present invention, any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort fall within the protection scope of the present invention.
