Description

Technical Field

[0001] The utility model is applicable to the technical field of water conservancy projects, and particularly relates to a column pulling device for water conservancy projects. Background Art

[0002] At present, in the excavation work of water conservancy projects, a large number of piles are usually driven around the construction site to prevent the foundation from collapsing. After the project is completed, the piles are pulled out for subsequent construction use.

[0003] However, nowadays, when the column is being pulled out, in order to speed up the pulling out speed, the construction workers often shovel the soil around the column to loosen it, so as to avoid the soil from sticking to it and affecting its use when the column is pulled out. This construction operation method increases the labor consumption of the construction workers too much, thereby affecting the pulling out efficiency of the column. Therefore, we propose a column pulling device for water conservancy projects. Utility Model Content

[0004] The main purpose of the utility model is to provide a column pulling device for water conservancy projects, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A column extraction device for water conservancy engineering, comprising a mounting base, a driving frame is vertically fixedly mounted on the top side surface of the mounting base, a pulling clamp ring is movably mounted on the top side of the driving frame, a mounting plate is movably mounted on the bottom surface of the mounting base, and a hollow frame is slidably mounted on the bottom side surface of the mounting plate;

[0007] A fixing ring is fixedly mounted on the outer surface of the bottom of the mounting plate, a transmission gear ring is fixedly mounted on the inner surface of the fixing ring, a servo motor is fixedly mounted on the inner top surface of the hollow frame, the bottom surface of the servo motor transmission shaft is connected to the rotating rod through a coupling, a transmission gear is fixedly sleeved on the outer surface of the rotating rod, and the transmission gear is meshed with the outer side of the transmission gear ring;

[0008] A rotating groove is provided on the side of the hollow frame, and a transmission gear is rotatably installed inside the rotating groove. A loosening frame is fixedly installed on the bottom surface of the outer side of the hollow frame.

[0009] By adopting the above technical solution, through the meshing transmission action of the transmission gear and the transmission gear ring, and the loosening frame is installed on the outside of the hollow frame, the loosening frame can stir and loosen the soil on the outside of the column pile to be pulled out inside the plug-in slot, while ensuring the column pile pulling speed and reducing the labor consumption required for the operator to manually loosen the soil.

[0010] As an optional solution of the technical solution of the present application, fixed frames are fixedly installed on both side surfaces of the top of the mounting base, an electric push rod is fixedly installed on the inner top surface of each fixed frame, and the bottom surface of the electric push rod transmission shaft is fixedly connected to the top surface of the mounting plate.

[0011] By adopting the above technical solution, the power required for the vertical movement of the mounting plate and the loosening frame is provided through the structural action of the electric push rod.

[0012] As an optional solution of the technical solution of the present application, a guide block is fixedly installed on the top surface of the hollow frame, a guide groove is opened at the bottom of the mounting plate, and the guide block is slidably inserted into the guide groove.

[0013] By adopting the above technical solution, the rationality of movement of the entire device is ensured by the guiding sliding action of the guide groove on the guide block.

[0014] As an optional solution of the technical solution of the present application, the middle ends of the mounting base and the mounting plate are provided with plug-in slots, and support frames are fixedly installed on the four corner surfaces of the bottom of the mounting base, and the support frames are located on the outside of the mounting plate.

[0015] By adopting the above technical solution, the pulling-out stability of the column pile to be pulled out is ensured by the structural effect of the plug-in groove.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is a column pulling device for water conservancy projects. A mounting plate and a fixing ring are arranged under the mounting base. Under the meshing transmission action of the transmission gear and the transmission gear ring, the servo motor drives the transmission gear to rotate synchronously when it is running, and then drives the transmission gear and the hollow frame to move synchronously under the mounting base, thereby driving the loosening frame located at the bottom of the outer side of the hollow frame to rotate synchronously in a circle under the mounting base, so that the loosening frame can stir and loosen the soil outside the column to be pulled out in the plug-in slot, thereby ensuring the speed of pulling out the column and reducing the labor consumption required for the operator to loosen the soil manually.

[0018] 2. The technical solution of the present application is a column pulling device for water conservancy projects. An electric push rod is arranged on the top of the installation base. The operation of the electric push rod can drive the power required for the vertical movement and adjustment of the installation plate and the loosening frame, thereby ensuring that the loosening frame can be quickly inserted into the soil outside the column pile, further improving the loosening quality of the sticky soil outside the column pile, and increasing the pulling out speed of the column pile.
