The skilled in the art can reasonably determine the specific meaning of the above words in the utility model according to the specific content of the technical scheme.

[0044] Referring to Figure 1 , Figure 2 The utility model discloses a device suitable for adjusting the elevation of the chamfer steel mould of the inner mould of the beam forming machine, which is characterized by the following technical scheme.

[0045] The first connecting plate 3 is arranged on the chamfer steel mould 1.

[0046] The second connecting plate 4 is arranged opposite to the first connecting plate 3 and has a plurality of second connecting plates 4 arranged along the height direction of the inner mould 2. Each second connecting plate 4 is provided with a guide hole 5, and the guide hole 5 is linearly arranged along the height direction of the inner mould 2. The linear arrangement of the guide hole 5 along the height direction ensures the smooth and accurate movement of the lifting rod 6 during the adjustment process, avoids deviation, and improves the adjustment accuracy.

[0047] The lifting rod 6 comprises a first end and a second end arranged oppositely. The first end of the lifting rod 6 can pass through each guide hole 5 of each second connecting plate 4.

[0048] The conversion seat 7 is connected with the second end of the lifting rod 6.

[0049] The rotating arm 8 comprises a first end and a second end arranged oppositely, and the first end and the second end of the rotating arm 8 are rotatably connected to the first connecting plate 3 and the conversion seat 7 respectively.

[0050] A traction mechanism is arranged for lifting the boom 6 to adjust the relative height and / or angle of the chamfered steel form 1 and the inner form 2.

[0051] Since the cross section of the bridge is variable, the cross section height changes constantly at different beam segments, and therefore the height of the inner form 2 needs to be changed in real time to adapt to the change of the beam surface during construction. By simultaneously adjusting the height of the boom 6 and the angle of the rotating arm 8 to adapt to the change of the bottom plate of different beam segments, the design height of the corresponding segment bottom plate is overlapped. By using the adjustable chamfered steel form 1, the cutting operation of the inner form 2 is avoided, the loss of the formwork is significantly reduced, the service life of the formwork is prolonged, and the construction cost is reduced. The traditional beam former needs to cut the bottom formwork of the inner form 2 to adapt to the height change of different beam segments, which causes the problem of formwork waste.

[0052] In one embodiment, an ear seat 9 is arranged between the first end of the rotating arm 8 and the first connecting plate 3, the ear seat 9 comprises a first seat body 91 and a first lifting lug 92 arranged on the seat body, the seat body is provided with a sleeve opening through which the first connecting plate 3 passes, and the first end of the rotating arm 8 is rotatably connected to the first lifting lug 92.

[0053] In one embodiment, a first pin shaft 93 is installed between the first end of the rotating arm 8 and the first lifting lug 92. The rotating arm 8 can be smoothly rotated during adjustment, and the firmness of the connection is maintained.

[0054] In one embodiment, the conversion seat 7 comprises a second seat body 71 and a second lifting lug 72 arranged on the second seat body 71, the second end of the boom 6 is connected to the second seat body 71, and the second end of the rotating arm 8 is rotatably connected to the second lifting lug 72.

[0055] In one embodiment, a second pin shaft 73 is installed between the second end of the rotating arm 8 and the second lifting lug 72. The rotating arm 8 can be smoothly rotated during adjustment, and the firmness of the connection is maintained.

[0056] In one embodiment, the second seat body 71 comprises a mounting plate 74, and the second end of the boom 6 passes through the mounting plate 74 and is connected to the mounting plate 74 through a nut assembly (mounting nut, gasket, etc.).

[0057] In one embodiment, a locking nut 61 is further included, which is threadedly connected to the boom 6 and used to abut against the second connecting plate 4. The locking nut 61 is used to fix the position between the boom 6 and the second connecting plate 4, to ensure the stability of the device during the pouring process, and to prevent the displacement of the inner mold 2. The use of the locking nut 61 is simple, and the locking nut 61 can be quickly locked or loosened, which is convenient for the operator to adjust at different construction stages.

[0058] In one embodiment, the traction mechanism includes a manual hoist connected to the chamfer steel mold 1 or the boom 6. The manual hoist has a simple structure and is easy to install, which improves the convenience of operation. A lifting ring or a fixed support can be installed at a proper position of the boom 6. The hook ring of the manual hoist is connected to the lifting ring or the fixed support on the boom 6 through a steel wire rope or a chain. Alternatively, a lifting ring or a fixed support can be installed at a fixed position (such as a reserved connecting hole or a reinforcing structure) of the chamfer steel mold 1. The hook ring of the manual hoist is connected to the lifting ring or the fixed support on the chamfer steel mold 1 through a steel wire rope or a chain.

[0059] In one embodiment, the boom 6 is provided with at least two booms, which are respectively located at both ends of the chamfer steel mold 1 in the length direction, to ensure that the chamfer steel mold 1 is uniformly stressed during the adjustment process and to avoid deflection or instability. It can be understood that each boom 6 corresponds to the installation of one traction mechanism.

[0060] The principle of the utility model is as follows: when it is necessary to adjust the elevation of the chamfer steel mold 1 at the bottom of the inner mold 2, the operator lifts or lowers the boom 6 through the manual hoist, the vertical movement of the boom 6 drives the conversion seat 7 and the rotating arm 8 to move together, the relative height and angle between the chamfer steel mold 1 and the inner mold 2 are accurately adjusted through the change of the rotating angle of the rotating arm 8. After the adjustment is completed, the wooden mold 10 is installed between the chamfer steel mold 1 and the inner mold 2 for fixation, and the pouring of concrete is carried out, to ensure the stability of the chamfered part during the pouring process of the concrete. After the pouring is completed, the wooden mold 10 is removed, and when the beam forming machine and the inner mold 2 move to the next specified position, the construction of the next beam section is completed.

[0061] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the utility model and not to limit it. Although the utility model has been described in detail with reference to the examples, it should be understood by those skilled in the art that the technical solutions of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the utility model, and all of them should be covered in the scope of the claims of the utility model.
