Description

Technical Field

[0001] This utility model relates to the technical field of hanging basket construction equipment, and in particular to a main truss and a hanging basket mobile formwork bridge building machine. Background Technology

[0002] Mobile formwork bridge-building machines are construction machines that use self-contained formwork and piers or abutments as supports to cast concrete on-site for bridges. Their main features include high-quality construction, simple operation, and low cost. They are widely used in the construction of continuous beams for highway and railway bridges and are considered a relatively advanced construction method.

[0003] Existing mobile formwork bridge-building machines can be divided into upper-bearing and lower-bearing types. Due to the limitations of the load-bearing capacity of lower-bearing mobile formwork bridge-building machines, they are only suitable for small and medium-sized single-box single-cell bridges. For large bridges, such as... Figure 1 The multi-cell bridges and cable-stayed bridges shown primarily utilize steel box girder mobile formwork bridge-building machines. The main truss of these machines is a steel box structure, which improves the overall integrity of traditional hanging baskets and enables automatic adjustment and movement of the formwork.

[0004] However, the existing steel box-type upper-bearing mobile formwork bridge building machine, with the main truss of the steel box structure arranged along the bridge direction on both sides of the beam, results in too little space on both sides of the steel box structure, making the structure huge. It is inconvenient for construction personnel to enter the top surface of the beam from both sides of the bridge direction for construction, and it is also inconvenient for hoisting. Utility Model Content

[0005] In view of this, the present invention provides a main truss of an upper-bearing mobile formwork bridge building machine and an upper-bearing mobile formwork bridge building machine, which greatly improves the working space on the beam surface of the bridge building machine, making it easier for construction personnel to work. At the same time, the main truss units can be arbitrarily combined, adapting to single-box multi-chamber situations, and have wider adaptability.

[0006] A main truss of an upper-bearing mobile formwork bridge-building machine includes at least two sets of main truss units, which are sequentially arranged on the top of the beam along the bridge direction. Each main truss unit is a quadrilateral plate-like structure formed by connecting a straight side and three oblique sides sequentially, and the quadrilateral plate-like structure has weight-reducing holes. The bottom of each main truss unit is planar. A first hanging part and a second hanging part are respectively provided at the first and second ends of each main truss unit. The connection surface between the second end of the main truss unit and the bottom of the main truss unit is inclined, so that the second end of the main truss unit forms a first gap with the top of the beam. A third hanging part is provided in the middle of each main truss unit. The second hanging parts of two adjacent main truss units at opposite ends of the main truss along the bridge direction are arranged adjacently, so that a second gap is formed between the two adjacent main truss units.

[0007] In one embodiment, the two ends of the quadrilateral plate structure are respectively connected to the first hanging part and the second hanging part to form a duckbill-like structure.

[0008] Based on the same concept as the aforementioned utility model, this application also provides an upper-bearing mobile formwork bridge building machine, including a bottom basket and a main truss as described above. The main truss unit is arranged sequentially on the top of the beam along the bridge direction. The front upper crossbeam and the rear upper crossbeam of the bottom basket are detachably suspended from the first suspension part and the third suspension part, respectively, and the second suspension part is detachably connected to the beam.

[0009] In one embodiment, the bridge-building machine further includes an anchoring assembly and a rear anchor beam; wherein the rear anchor beam is disposed above the second suspension part along the transverse direction of the bridge, and the anchoring assembly is disposed on both sides of the second suspension part along the longitudinal direction of the bridge and detachably connects the rear anchor beam and the beam body.

[0010] In one embodiment, the anchoring assembly includes two spreader beams spaced apart along the height direction of the beam body. The two spreader beams are arranged along the longitudinal direction of the bridge, and a connector is provided between the two ends of the two spreader beams. The two spreader beams are detachably connected to the rear anchor beam and the beam body.

[0011] In one embodiment, the upper-bearing mobile formwork bridge-building machine further includes tracks, which are respectively disposed on both sides of the top of the beam along the bridge direction. The bottom of the main truss unit is provided with a sliding seat at the end away from the second hanging part, and the sliding seat is slidably disposed on the tracks. The bottom of the sliding seat is detachably provided with a first support part, and the bottom of the tracks is provided with a second support part along the bridge direction. When the main truss is in a fixed state, the first support part abuts against the second support part. When the main truss is in a traveling state, the first support part disengages from the second support part.

[0012] In one embodiment, the track is provided with an anti-top wheel assembly, the anti-top wheel assembly including a mounting member fixedly connected to the second hanging part, the mounting member being provided with an anti-top wheel that is rotatably connected to the track, and the rotation axis of the anti-top wheel being perpendicular to the track.

[0013] In one embodiment, the bottom of the mounting component is provided with symmetrical snap-fit ​​portions, which snap into the top inner side of the track.

[0014] In one embodiment, the two ends of the rear anchor beam are provided with rear C-shaped hooks, the hooking part of the rear C-shaped hook is located below the beam and faces the beam in the transverse direction, and the hooking part of the rear C-shaped hook is provided with a rear protective platform.

[0015] The main truss of the upper-bearing mobile formwork bridge building machine and the upper-bearing mobile formwork bridge building machine provided in this application are characterized by the main truss being composed of quadrilateral plate-shaped main truss units with weight-reducing holes on the plate-shaped structure. The second end of the main truss unit forms a first notch with the top of the beam, and a second notch is formed between two adjacent main truss units. This greatly increases the working space on the beam surface of the bridge building machine, making it easier for construction personnel to work. At the same time, the main truss units can be arbitrarily combined, adapting to single-box multi-chamber situations, thus having wider adaptability. Attached Figure Description

[0031] Example 1

[0032] like Figures 2 to 4As shown, the main truss 10 of the upper-bearing mobile formwork bridge-building machine of this application embodiment includes at least two sets of main truss units 12. The main truss units 12 are arranged sequentially on the top of the beam 101 along the longitudinal direction of the bridge. The main truss unit 12 is a quadrilateral plate-like structure formed by connecting a straight side and three oblique sides in sequence. The quadrilateral plate-like structure is provided with weight-reducing holes 121. The bottom of the main truss unit 12 is a planar structure. The first end and the second end of the main truss unit 12 are respectively provided with a first hanging part 122 and a second hanging part 122. The main truss unit 12 has a third hanging part 124 in the middle of the hanging part 123; the connecting surface between the second end of the main truss unit 12 and the bottom of the main truss unit 12 is inclined, so that the second end of the main truss unit 12 and the top of the beam 101 form a first gap 125 that is similar to a triangle; the second hanging parts 123 of the two adjacent main truss units 12 at opposite ends of the main truss 10 along the bridge direction of the beam 101 are arranged adjacently, so that a second gap 127 that is similar to a V-shape is formed between the two adjacent main truss units 12.

[0033] In one embodiment, the sloping side of the top of the quadrilateral plate structure is inclined downwards, and the two ends of the quadrilateral plate structure are connected to the first hanging part 122 and the second hanging part 123 respectively to form a duckbill-like structure. Specifically, the main truss 10 is formed by welding sheet metal, and hollow weight-reducing holes 121 and truss beam reserved holes 126 are cut on the main plate.

[0034] The main truss of the upper-bearing mobile formwork bridge-building machine provided in this application embodiment is applicable to multi-box bridge structures. It adopts a duckbill-shaped main truss steel box and the main truss 10 is composed of quadrilateral plate-shaped main truss units 12. The plate-shaped structure is provided with hollow weight-reducing holes 121. The second end of the main truss unit 12 forms a first notch 125 with the top of the beam 101, and a second notch 127 is formed between two adjacent main truss units 12. This greatly improves the beam surface working space of the bridge-building machine, making it easier for construction personnel to work. At the same time, the main truss units 12 can be arbitrarily combined to adapt to the situation of single box multi-chamber, and has a wider adaptability.

[0035] Example 2

[0036] like Figure 2 As shown, the upper-bearing mobile formwork bridge-building machine of this application includes the main truss 10 and the bottom basket 20 of the aforementioned embodiment. The main truss unit 12 of the main truss 10 is arranged along the bridge direction of the beam 101 on the front upper crossbeam 21 and the rear upper crossbeam 23 of the bottom basket 20 at the top of the beam 101, respectively detachably suspended by the first suspension part 122 and the third suspension part 124. The second suspension part 123 is detachably connected to the beam 101.

[0037] Obviously, the upper-bearing mobile formwork bridge-building machine according to the embodiments of this application has all the advantages and technical effects of the aforementioned embodiments because it is equipped with the main truss of the upper-bearing mobile formwork bridge-building machine of the aforementioned embodiments.

[0038] like Figure 2 , Figure 5 , Figure 6 As shown, in one embodiment, the bridge-building machine further includes an anchoring assembly 30 and a rear anchor beam 41; wherein, the rear anchor beam 41 is disposed above the second suspension part 123 along the transverse direction of the bridge, and the anchoring assembly 30 is disposed on both sides of the second suspension part 123 along the longitudinal direction of the bridge and detachably connects the rear anchor beam 41 and the beam body 101. In one embodiment, the anchoring assembly 30 includes two spreader beams 31 spaced apart along the height direction of the beam body 101, the two spreader beams 31 are disposed along the longitudinal direction of the bridge, and a connector 32 is provided between the two ends of the two spreader beams 31; the two spreader beams 31 are detachably connected to the rear anchor beam 41 and the beam body 101 respectively. Specifically, a rear anchor beam 41 is provided above the tail of the main truss unit 12, which is anchored by upper and lower double spreader beams to provide downward pressure to the main truss unit 12 and prevent it from overturning. Since the force on the rear support of the main truss unit 12 is mainly applied to the rear anchor beam 41, the positional accuracy requirements for the spreader beams and the anchoring reserved holes on the beam body are low.

[0039] like Figure 2 As shown, in one embodiment, the bridge-building machine further includes a track 51, which is respectively located on both sides of the top of the beam 101 along the bridge direction. A slide 52 is provided at the bottom of the main truss unit 12 away from the second hanging part 123, and the slide 52 is slidably mounted on the track 51. A first support part 53 is detachably provided at the bottom of the slide 52, and a second support part 54 is provided at the bottom of the track 51 along the bridge direction. When the main truss 10 is in a fixed state, the first support part 53 abuts against the second support part 54. When the main truss 10 is in a traveling state, the first support part 53 disengages from the second support part 54. Specifically, the front support point of the main truss unit 12 is the slide 52. During pouring, a block-shaped first support part 53 is added below the slide 52 to abut against the second support part 54, so that the second support part 54, i.e., the pad beam, is directly subjected to the downward pressure of the front support point of the main truss unit 12. The track 51 is not subjected to the downward pressure of the main truss unit 12, thereby greatly avoiding damage to the track 51 and affecting construction.

[0040] like Figure 7 and Figure 8As shown, in one embodiment, a counter-rotating wheel assembly 60 is provided on the track 51. The counter-rotating wheel assembly 60 includes a mounting member 61 fixedly connected to the second hanging part 123. The mounting member 61 is provided with a counter-rotating wheel 62 that is rollably connected to the track 51, and the axis of rotation of the counter-rotating wheel 62 is perpendicular to the track 51. In one embodiment, a snap-fit ​​part 63 is symmetrically provided at the bottom of the mounting member 61, and the snap-fit ​​part 63 snaps into the inner top of the track 51. The counter-rotating wheel assembly 60 is located on the rear support point of the main truss 10, and the counter-rotating wheel 62 is snapped onto the track 51, which can effectively prevent the main truss 10 from tilting forward when traveling. Specifically, when the main truss 10 travels, the track anchor points and the rear support anchor points of the main truss 10, i.e. the anchor points of the anchoring assembly 30, are removed from the main truss 10's moving path. The main truss 10 is then lifted, the first support 53 is removed, and the track 51 is subjected to downward pressure from the main truss 10. The main truss 10 moves on the track 51 via the sliding seat 52 at the front support point and the anti-roll wheel 62 at the rear support point.

[0041] like Figure 9 As shown, in one embodiment, the rear anchor beam 41 is provided with rear C-shaped hooks 71 at both ends. The hooking part of the rear C-shaped hook 71 is located below the beam 101 and faces the beam 101 in the transverse direction. The hooking part of the rear C-shaped hook 71 is provided with a rear protective platform 72. Specifically, by providing rear protective platforms 72 at both ends of the rear C-shaped hooks 71 on the rear anchor beam 41, it is convenient for construction personnel to safely complete the anchoring of the rod at this location.

[0042] As can be seen from the above embodiments, the main truss and the main truss of the bridge-building machine with upper-bearing mobile formwork involved in this application greatly improve the working space on the beam surface of the bridge-building machine, making it easier for construction personnel to work. At the same time, the main truss units can be arbitrarily combined, adapting to the situation of single box with multiple chambers, and have wider adaptability.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily obtained by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
