Description

Technical Field

[0001] The utility model relates to the technical field of deep foundation pits, in particular to an auxiliary device for pouring concrete of a wall below a deep foundation pit cover plate. Background Art

[0002] A deep foundation pit refers to a project with an excavation depth of more than 5 meters (including 5 meters), or a project with a depth of less than 5 meters but with particularly complex geological conditions, surrounding environment and underground pipelines. The foundation pit project mainly includes the design and construction of the foundation pit support system and earth excavation, and is a highly comprehensive system project. It requires close cooperation between geotechnical engineering and structural engineering technicians, especially for the operation of the wall concrete under the cover plate inside the deep foundation pit. The existing technology is to directly pump concrete from the concrete tank truck to the pouring point below, and then manually hold the end of the pump pipe to pour the inner wall of the deep foundation pit. The pump pipe is often not long enough or the angle is wrong, and the innermost side under the cover plate cannot be poured. In addition, the deeper the foundation pit, the greater the pumping pressure and the higher the risk factor. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a wall concrete pouring auxiliary device below a deep foundation pit cover plate, so as to overcome the deficiencies in the above-mentioned prior art.

[0004] The technical solution of the utility model to solve the above technical problems is as follows: an auxiliary device for pouring concrete on the wall below the deep foundation pit cover, comprising: an operating platform and a moving mechanism, an aggregate tank is fixed on the operating platform, the feed port of the aggregate tank is connected to the tank truck through a conveying pipe, the concrete in the aggregate tank is pumped into the feed end of the nozzle, the discharge end of the nozzle is fixed on the moving mechanism, and its height and angle are adjusted by the moving mechanism.

[0005] On the basis of the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, a stirrer is fixed in the aggregate tank.

[0007] Furthermore, the moving mechanism includes: a moving frame, a driven gear that rotates horizontally on the moving frame, a motor that is fixed on the moving frame, a driving gear that meshes with the driven gear that is fixed on the main shaft of the motor, a driven frame that is fixed on the driven gear, a cylinder that is vertically fixed on the driven frame, and a discharge end of the nozzle that is fixed on the piston rod of the cylinder, and the cylinder and the motor are electrically connected to the controller respectively.

[0008] Furthermore, a slide block is arranged on the driven frame for vertical sliding, the discharge end of the nozzle is fixed on the slide block, and the piston rod of the cylinder is fixed to the slide block.

[0009] Furthermore, it also includes two sets of slide rails, which are fixed on the ground in the foundation pit, and the operating platform and the moving mechanism are slidably arranged on the two sets of slide rails respectively.

[0010] The beneficial effects of the utility model are:

[0011] The operating platform and the mobile mechanism are placed on the ground at the inner side wall of the deep base layer. The tank truck transports the concrete to the aggregate tank through the conveying pipe, and then the concrete in the aggregate tank is pumped into the feed end of the nozzle. Since the discharge end of the nozzle is fixed on the mobile mechanism, and the mobile mechanism can adjust the height and angle of the discharge end of the nozzle, the wall can be uniformly poured in layers and sections in all directions. In addition, the pouring position can be changed by controlling the position of the operating platform and the mobile mechanism.

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] Example 1

[0020] like Figure 1 to Figure 4As shown, a concrete pouring auxiliary device for the wall below the deep foundation pit cover plate comprises: an operating platform 4 and a moving mechanism 7, a material collection tank 5 is fixed on the operating platform 4, a material feed port of the material collection tank 5 is connected to a tank truck 2 via a conveying pipe 3, and concrete in the material collection tank 5 is pumped into the feeding end of a nozzle 6; the discharge end of the nozzle 6 is fixed on the moving mechanism 7, and its height and angle are adjusted by the moving mechanism 7, that is, the moving mechanism 7 can adjust the height and angle of the discharge end of the nozzle 6;

[0021] The workflow is as follows:

[0022] The tank truck 2 transports the concrete to the aggregate tank 5 through the conveying pipe 3, and then the concrete in the aggregate tank 5 is pumped into the feeding end of the nozzle 6. Since the discharge end of the nozzle 6 is fixed on the moving mechanism 7, and the moving mechanism 7 can adjust the height and angle of the discharge end of the nozzle 6, the wall can be uniformly poured in layers and sections in all directions. In addition, the pouring position can be changed by controlling the position of the operating platform 4 and the moving mechanism 7. The auxiliary device can realize the all-round layered and segmented pouring of the wall, and has a simple structure and a high safety factor.

[0023] Example 2

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment is a further improvement on the basis of embodiment 1, and the details are as follows:

[0025] A stirrer is fixed in the aggregate tank 5, and the stirrer is used to stir the concrete entering the aggregate tank 5 to prevent the concrete from solidifying or segregating.

[0026] Example 3

[0027] like Figure 3 , Figure 4 As shown, this embodiment is a further improvement on the basis of Embodiment 1 or 2, and the details are as follows:

[0028] The moving mechanism 7 includes: a moving frame 71, the moving frame 71 is horizontally rotatably connected to a driven gear 74, a motor 72 is fixed on the moving frame 71, a driving gear 73 is fixed on the main shaft of the motor 72, and the driving gear 73 is meshed with the driven gear 74, a driven frame 75 is fixed on the driven gear 74, a cylinder 76 is vertically fixed on the driven frame 75, and the discharge end of the nozzle 6 is fixed on the piston rod of the cylinder 76, the cylinder 76 and the motor 72 are electrically connected to the controller respectively, the controller can control the extension and contraction of the cylinder 76, and the controller can control the forward and reverse rotation of the motor 72;

[0029] The workflow is as follows:

[0030] During the pouring process, by starting the motor 72, the motor 72 will drive the driving gear 73 to rotate. Since the driving gear 73 is meshed with the driven gear 74, the driving gear 73 will drive the driven gear 74 to rotate. During the rotation of the driven gear 74, the driven frame 75 will be driven to rotate, thereby realizing the swing of the discharge end of the nozzle 6. At the same time, the cylinder 76 is controlled to extend and retract to realize the up and down movement of the discharge end of the nozzle 6. The two work together to change the position of the nozzle 6 to realize all-round layered and segmented pouring of the wall. The structure is simple and the safety factor is high.

[0031] Furthermore, a slider 751 is vertically slidably arranged on the driven frame 75, the discharge end of the nozzle 6 is fixed on the slider 751, and the piston rod of the cylinder 76 is fixed to the slider 751. This method can ensure the stability of the nozzle 6 during movement.

[0032] Example 4

[0033] like Figure 2 As shown, this embodiment is a further improvement on the basis of Embodiment 1, 2 or 3, and the details are as follows:

The operating platform 4 and the moving mechanism 7 are respectively slidably set on the two sets of slide rails 8. By controlling the positions of the moving mechanism 7 and the operating platform 4 on the slide rails 8, the pouring position can be automatically changed. The introduction of the slide rails 8 facilitates the movement of the operating platform 4 and the moving mechanism 7, and can ensure stability during the movement, and ensure that the distance between the moving mechanism 7 and the wall is constant.
