Description

Technical Field

[0001] This utility model relates to the technical field of hanging basket construction equipment, specifically an inner guide beam hoisting structure for a mobile formwork bridge building machine and the 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] In existing mobile formwork bridge-building machines, the front hanger of the inner guide beam is suspended from the upper front crossbeam of the machine, while the rear hanger is anchored to the already cast beam via suspension rods. Currently, both the front and rear hangers of the inner guide beam are typically rectangular frames fitted onto the inner guide beam. However, due to the presence of an inner formwork back frame inside the already cast beam during the pouring process, the lifting point position of the rear hanger on the cast beam is severely restricted, requiring it to avoid the location of the inner formwork back frame, thus affecting construction efficiency. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides an inner guide beam hoisting structure and a mobile formwork bridge-building machine, which can effectively increase the hoisting point range of the rear hanger and slide of the inner guide beam, making the position of the rear hoisting point of the inner guide beam and the hoisting point of the slide more flexible, and making it easier to design the position of the main truss ladder on the ground of the mobile formwork bridge-building machine, thereby improving the efficiency of construction operations.

[0005] To achieve the above objectives, this utility model provides an inner guide beam hoisting structure for a mobile formwork bridge-building machine, including a front hanger, a rear hanger, and a slide; wherein, the front hanger is detachably fitted onto the inner guide beam and is suspended from the front upper crossbeam of the mobile formwork bridge-building machine; the rear hanger includes a first supporting beam and a first connecting structure disposed on the top of the first supporting beam, the first connecting structure being detachably connected to the inner guide beam, and both ends of the first supporting beam being suspended from the cast-in-place beam; the slide includes a second supporting beam and a second connecting structure disposed on the top of the second supporting beam, the second connecting structure being slidably connected to the inner guide beam, and both ends of the second supporting beam being suspended from the cast-in-place beam.

[0006] In one embodiment, the first connecting structure includes two first skeleton plates disposed opposite each other on the top of the first supporting beam along the transverse direction of the bridge; a first pin and a second pin are spaced apart between the two first skeleton plates along the height direction of the cast beam, and both the first pin and the second pin pass through the two first skeleton plates along the transverse direction of the bridge; the inner guide beam is located between the two first skeleton plates and below the first pin, and the second pin passes through the inner guide beam.

[0007] In one embodiment, when there are two or more inner guide beams, there are multiple first connecting structures that correspond one-to-one with the inner guide beams; some or all of the first connecting structures are provided on the same first support beam, and the first connecting structure is detachably connected to the corresponding inner guide beam.

[0008] In one embodiment, the second connecting structure includes two second skeleton plates disposed opposite each other on the top of the second supporting beam along the transverse bridge direction; a third pin and a roller are spaced apart between the two second skeleton plates along the height direction of the cast beam, and the third pin passes through the two second skeleton plates along the transverse bridge direction, and the roller is rotatably connected to the two second skeleton plates along the transverse bridge direction; the inner guide beam is located between the two second skeleton plates and below the third pin, and the roller is located at the bottom of the inner guide beam.

[0009] In one embodiment, when there are two or more inner guide beams, there are multiple second connecting structures that correspond one-to-one with the inner guide beams; some or all of the second connecting structures are provided on the same second support beam, and the second connecting structures are slidably connected to the corresponding inner guide beams.

[0010] In one embodiment, the front hanger is a rectangular or U-shaped frame structure sleeved on the front end of the inner guide beam, and the front hanger is suspended on the front upper crossbeam of the mobile formwork bridge building machine.

[0011] In one embodiment, the front hanger is provided with a fourth pin, and the fourth pin passes through the inner guide beam in the transverse direction.

[0012] In one embodiment, when there are two or more inner guide beams, a connecting beam connects two adjacent inner guide beams.

[0013] Based on the same concept as the aforementioned utility model, this application also provides a mobile formwork bridge building machine, which is equipped with the inner guide beam hoisting structure of the mobile formwork bridge building machine as described above.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] The mobile formwork bridge-building machine provided by this utility model has an inner guide beam hoisting structure and a mobile formwork bridge-building machine. By setting a first support beam and a second support beam at the bottom of the rear hanger and the slide respectively, the rear hoisting point of the inner guide beam and the hoisting point of the slide are transferred to the first support beam and the second support beam. The first support beam and the second support beam of different lengths can be selected according to the needs, thereby effectively increasing the hoisting point range of the rear hanger and the slide of the inner guide beam. This allows for more convenient avoidance of the inner formwork back frame and makes it easier to design the position of the main truss ladder on the ground of the mobile formwork bridge-building machine, thereby improving the efficiency of construction operations.

[0030] like Figure 1 , Figure 2The diagram shows the inner guide beam hoisting structure of a mobile formwork bridge-building machine disclosed in this embodiment, including a front hanger 2, a rear hanger 3, and a slide 4. The front hanger 2 is detachably fitted onto the inner guide beam 1 and is suspended from the front upper crossbeam of the mobile formwork bridge-building machine. The rear hanger 3 includes a first supporting beam 301 and a first connecting structure 302 located on top of the first supporting beam 301. The first connecting structure 302 is detachably connected to the inner guide beam 1, and both ends of the first supporting beam 301 are suspended from the cast-in-place beam 7 by second lifting rods 6. The slide 4 includes a second supporting beam 401 and a second connecting structure 402 located on top of the second supporting beam 401. The second connecting structure 402 is slidably connected to the inner guide beam 1, and both ends of the second supporting beam 401 are suspended from the cast-in-place beam 7 by third lifting rods 8. It is worth noting that although the rear hanger 3 shown in this embodiment is between the front hanger 2 and the carriage 4, the carriage 4 can also be set between the rear hanger 3 and the front hanger 2 in specific applications.

[0031] This utility model, by setting a first support beam 301 and a second support beam 401, transfers the rear lifting point of the inner guide beam 1 and the lifting point of the slide 4 to the first support beam 301 and the second support beam 401. At the same time, the first support beam 301 and the second support beam 401 of different lengths can be selected according to the needs, thereby effectively increasing the lifting point range of the rear lifting frame 3 and the slide 4 of the inner guide beam 1. This allows for more convenient avoidance of the inner formwork back frame and makes it easier to design the position of the main truss ladder of the mobile formwork bridge building machine on the ground, thereby improving the efficiency of construction operations.

[0032] refer to Figure 3 , Figure 4 The first connecting structure 302 includes two first skeleton plates 3021 disposed opposite each other on the top of the first supporting beam 301 along the transverse direction of the bridge; a first pin 3022 and a second pin 3023 are provided between the two first skeleton plates 3021 along the height direction of the cast beam 7, and the first pin 3022 and the second pin 3023 both pass through the two first skeleton plates 3021 along the transverse direction of the bridge; the inner guide beam 1 is located between the two first skeleton plates 3021 and below the first pin 3022, and the second pin 3023 passes through the inner guide beam 1 to prevent the inner guide beam 1 from falling off the first connecting structure 302 due to shaking.

[0033] In specific implementation, when there are two or more inner guide beams 1, there are multiple first connecting structures 302, each corresponding one-to-one with an inner guide beam 1. The first connecting structure 302 is detachably connected to the corresponding inner guide beam 1, and some or all of the first connecting structures 302 are located on the same first supporting beam 301. In this embodiment, it is preferable that all the first connecting structures 302 are located on the same first supporting beam 301; for example, the illustration shows two first connecting structures 302 located on the same first supporting beam 301. Clearly, by detachably setting multiple sets of first connecting structures 302 on different or the same first supporting beams 301, different positions of the inner formwork back frame can be selectively avoided, thereby greatly improving construction efficiency.

[0034] refer to Figure 5 , Figure 6 The second connecting structure 402 includes two second frame plates 4021 positioned opposite each other on top of the second supporting beam 401 along the transverse bridge direction. A third pin 4022 and a roller 4023 are spaced apart between the two second frame plates 4021 along the height direction of the cast beam 7. The third pin 4022 passes through the two second frame plates 4021 along the transverse bridge direction, and the roller 4023 is rotatably connected to the two second frame plates 4021 along the transverse bridge direction, i.e., the axis of the roller 4023 extends along the transverse bridge direction. The inner guide beam 1 is located between the two second frame plates 4021 and below the third pin 4022, and the roller 4023 is located at the bottom of the inner guide beam 1 and rolls with it. Clearly, the positioning and guiding of the inner guide beam 1 by the cooperation of the third pin 4022 and the roller 4023 greatly improves the stability and reliability of the slide 4 during its sliding process.

[0035] In specific implementation, when there are two or more inner guide beams 1, there are multiple second connecting structures 402, each corresponding one-to-one with an inner guide beam 1. The second connecting structure 402 is slidably connected to the corresponding inner guide beam 1, and some or all of the second connecting structures 402 are located on the same second support beam 401. In this embodiment, it is preferable that all the second connecting structures 402 are located on the same second support beam 401; for example, the figure shows two second connecting structures 402 located on the same second support beam 401. Clearly, by detachably setting multiple sets of first connecting structures 302 on different or identical first support beams 301, different positions of the inner formwork back frame can be selectively avoided, thereby greatly improving construction efficiency.

[0036] like Figure 1 and Figure 2 As shown, the front hanger 2 is a rectangular or U-shaped frame structure fitted onto the front end of the inner guide beam 1, and the front hanger 2 is suspended on the front upper crossbeam of the mobile formwork bridge-building machine.

[0037] In the specific implementation process, a fourth pin is provided on the front hanger 2, and the fourth pin passes through the inner guide beam 1 to prevent the inner guide beam 1 from slipping off the front hanger 2 during construction. Additionally, when there are two or more inner guide beams 1, a connecting beam 9 connects adjacent inner guide beams 1 to improve the overall stability of the inner guide beam 1 hoisting. The rear hoisting point of the inner guide beam 1 can be located at both ends of the first support beam 301, and can be connected to the connecting beam 9 using slings to improve the stability and reliability of the rear hoisting point of the inner guide beam 1.

[0038] Based on the same concept as the foregoing embodiments, this application also provides a mobile formwork bridge-building machine, which is equipped with an inner guide beam hoisting structure as described in the foregoing embodiments. The above descriptions are merely preferred embodiments of this utility model and do not limit the scope of protection of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model, utilizing the description and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
