Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm wall construction, in particular to a diaphragm wall brushing device. Background Technique

[0002] The diaphragm wall is formed by using a grooving machine to excavate a long and narrow deep groove along the axis of the perimeter of the deep excavation project below the ground surface. Then, a steel reinforcement cage is lifted and placed in the groove, and underwater concrete is poured through the conduit method to form a continuous reinforced concrete wall. Such a wall can not only effectively prevent groundwater seepage but also serve as a retaining structure to bear the weight of the upper structure, ensuring the stability and safety of the project; during the construction of the diaphragm wall, it is necessary to brush the end face of the unit groove to ensure that the soil attached to the end face is washed away, reducing the impact on subsequent pouring. When the existing brushing tools are used for brushing, it is not easy to control the distance between the tool and the end face, and the brushing efficiency is relatively low. Content of the Utility Model

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to provide a diaphragm wall brushing device.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A diaphragm wall brushing device includes a frame and a lifting ring installed at the top thereof. A diversion mechanism is installed inside the frame. A plurality of horizontally arranged mounting seats are installed on one side of the frame. An installation opening is provided at the front end of the mounting seat. A double-headed brush is detachably arranged in the installation opening. The working end of the double-headed brush is located outside the installation opening, and the non-working end is located inside the installation opening.

[0006] Preferably, the diversion mechanism includes an upper connecting rod, a middle connecting rod, and a lower connecting rod that are sequentially installed on the frame from top to bottom. The middle connecting rod is rotatably connected to a plurality of rotating plates through a rotating shaft. An elastic member is arranged on the rotating shaft, and both ends of the elastic member are connected to the rotating plate and the middle connecting rod respectively. An upper stop rod and a lower stop rod are respectively arranged on the upper connecting rod and the lower connecting rod. The upper end of the rotating plate is inclined towards the mounting seat side.

[0007] Preferably, the mounting seat and the double-headed brush are connected by a plurality of fastening bolts arranged in a straight line.

[0008] Preferably, a limiting strip is arranged on the side wall of the double-headed brush.

[0009] Preferably, a reinforcing rib is arranged between the mounting seat and the frame.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: The utility model uses a crane to slowly lower the frame into the diaphragm wall trench through a lifting ring. After reaching the bottom, the frame is pulled upward, and the muddy water in the trench acts vertically on the rotating plate, generating a vertically downward resistance and a pressure towards the double-headed brush, driving the double-headed brush to closely adhere to the end face of the diaphragm wall, ensuring that the double-headed brush cleans the end face, avoiding the situation where there is a gap between the double-headed brush and the end face, resulting in low cleaning efficiency or even inability to clean. Moreover, when the outer end of the double-headed brush is severely worn, the inner and outer ends can be swapped to avoid the situation where the construction is stalled due to lack of components.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0017] Refer to Figures 1-3 , a device for brushing the wall of a diaphragm wall, comprising a frame 1 and a lifting ring 6 installed at the top thereof. A diversion mechanism is installed inside the frame 1. A plurality of horizontally arranged mounting seats 8 are installed on one side of the frame 1. An installation opening 11 is provided at the front end of the mounting seat 8. A double-headed brush 12 is detachably arranged in the installation opening 11. The working end of the double-headed brush 12 is located outside the installation opening 11, and the non-working end is located inside the installation opening 11.

[0018] Use a crane to slowly lower the frame 1 into the diaphragm wall trench through the lifting ring 6. After reaching the bottom, pull up the frame 1. The muddy water in the trench acts vertically on the rotating plate 5, generating a vertically downward resistance and a pressure towards the double-headed brush 12, driving the double-headed brush 12 to closely adhere to the end face of the diaphragm wall, ensuring that the double-headed brush 12 brushes and cleans the end face, avoiding the situation that there is a gap between the double-headed brush 12 and the end face, resulting in low cleaning efficiency or even inability to clean. Moreover, when the outer end of the double-headed brush 12 is severely worn, the inner and outer ends can be swapped to avoid the situation of lack of components leading to construction stagnation.

[0019] In this embodiment, the diversion mechanism includes an upper connecting rod 2, a middle connecting rod 3, and a lower connecting rod 4 that are sequentially installed on the frame 1 from top to bottom. The middle connecting rod 3 is rotatably connected with a plurality of rotating plates 5 through a rotating shaft 15. An elastic member is arranged on the rotating shaft 15, and both ends of the elastic member are connected to the rotating plate 5 and the middle connecting rod 3 respectively. Upper stop rods 7 and lower stop rods 14 are respectively arranged corresponding to the upper connecting rod 2 and the lower connecting rod 4. The upper end of the rotating plate 5 is inclined towards the mounting seat 8. The elastic member drives the rotating plate 5 to be inclined, and under the limitation of the upper stop rod 7 and the lower stop rod 14, it is ensured that it is in an inclined state.

[0020] In this embodiment, the mounting seat 8 and the double-headed brush 12 are connected by a plurality of fastening bolts 10 distributed linearly, which is convenient for switching the inner and outer ends.

[0021] In this embodiment, a limiting strip 13 is arranged on the side wall of the double-headed brush 12. When the limiting strip 13 contacts the mounting opening 11, the fastening bolts 10 are aligned with the screw holes on the mounting seat 8 and the double-headed brush 12, realizing its quick positioning and installation.

[0022] In this embodiment, a reinforcing rib 9 is arranged between the mounting seat 8 and the frame 1 to enhance the connection strength.

[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
