Description

Technical Field

[0001] The utility model belongs to the technical field of building construction machinery manufacturing and relates to a pulley used for finishing the surface of cast-in-place concrete. Background Art

[0002] In the process of pouring concrete for a building, the concrete surface needs to be smoothed in the final stage. There are also some auxiliary finishing devices in the prior art, but these auxiliary finishing devices are aimed at the flat surface of the entire building or the entire bridge deck. When finishing the local surfaces such as the drainage holes of the building or bridge deck, the auxiliary finishing devices cannot perform local fine finishing and need to be finished manually.

[0003] According to the requirements of bridge deck waterproofing design, the concrete at the drainage hole location needs to be finished when it is close to initial setting, so that a smooth and round surface can be formed after the construction of the drainage hole on the bridge deck. In the traditional finishing process, wooden boards need to be laid, and the workers squat on the wooden boards to finish the initial setting concrete. Since the wooden boards are laid on the concrete, the places where the wooden boards are laid need to be finished again after the finishing is completed. The finishing efficiency is low and the construction time is long.

[0004] Based on the above problems, the utility model provides a pulley for finishing the cast-in-place concrete surface. Utility Model Content

[0005] The utility model aims to provide a pulley for finishing the surface of cast-in-place concrete, which can complete the finishing work of the drain hole through the finishing pulley, improve the finishing efficiency and shorten the construction time.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A pulley for finishing cast-in-place concrete, comprising a first connecting vertical plate, a bearing plate, a connecting horizontal plate, a second connecting vertical plate, and a ballast retaining wall;

[0008] The bearing plate is arranged on one side of the bottom of the first connecting vertical plate;

[0012] The first connecting vertical plate and the second connecting vertical plate are respectively slidably arranged on both sides of the ballast retaining wall;

[0015] Furthermore, a second moving wheel is provided on the other side of the bottom of the first connecting vertical plate, and the second moving wheel is slidably connected to a side surface of the bottom of the ballast retaining wall.

[0016] Furthermore, a third moving wheel is provided on one side of the bottom of the second connecting vertical plate, and the third moving wheel is slidably connected to the other side surface of the top of the ballast retaining wall.

[0017] Furthermore, a driving assembly is also provided at the bottom of the connecting transverse plate, and the driving assembly is transmission-connected to the first moving wheel.

[0030] As a preferred embodiment, a triangular support is used at the connection between the bearing plate 2 and the first connecting vertical plate 1 to improve the stability of the pulley.

[0035] like Figure 2 When in use, the whole device is placed on the ballast retaining wall 5, and the operator can "give force" by supporting with one hand, and the first moving wheel 6 will slide on the ballast retaining wall 5, and the second moving wheel 7 and the third moving wheel 8 will move on the side of the ballast retaining wall 5. Since there are movable pulleys on the upper part and the side, the operator standing on the pulley can drive the entire pulley forward by applying a very small force, and the operator squats on the bearing plate 2 of the pulley to complete the finishing of the drain hole; and the bearing plate of the pulley does not touch the concrete finishing position, so it will not cause damage to the concrete finishing, and it is necessary to re-finish the surface.

[0036] Embodiment 2: The pulley is expanded to move automatically, and a driving assembly 9 is further provided at the bottom of the connecting transverse plate 3 , and the driving assembly 9 is transmission-connected to the first moving wheel 6 .

[0037] Specifically, the driving assembly includes a driving motor 901, a driving gear 902, and a driven gear 903; the driving motor 901 is arranged at the bottom of the connecting cross plate 3; the driving gear 902 is transmission-connected to the output shaft of the driving motor 901; the driven gear 903 is meshed with the driving gear 902, and the output shaft of the driven gear 903 is connected to the first moving wheel 6.

[0040] As a preference, a driving motor is arranged on the second vertical plate 4, the output shaft of the driving motor is connected to the third moving wheel 8, and the driving motor drives the third moving wheel 8 to move forward.

[0041] When in use, the whole device is placed on the ballast retaining wall 5, and the operator starts the driving motor 901, and the driving motor 901 drives the active gear 902 and the driven gear 903 to rotate, thereby driving the first moving wheel 6 to slide on the ballast retaining wall 5, and the second moving wheel 7 and the third moving wheel 8 move on the side of the ballast retaining wall 5, which can drive the entire pulley to move forward, and the operator squats on the bearing plate 2 of the pulley to complete the surface finishing of the drainage hole.
