Utility Model Content

[0005] In order to solve the above problems, the utility model provides a device for detecting the bearing capacity of the foundation of a water conservancy project.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a device for detecting the bearing capacity of the foundation of a water conservancy project, comprising a mounting plate, four supporting legs distributed in a rectangular array are fixed at the bottom of the mounting plate, and a roller is arranged at the lower end of each supporting leg. A detection component for detecting the bearing capacity of the foundation is installed at the bottom of the mounting plate, and the detection component includes a cylinder fixed to the bottom of the mounting plate, a bearing capacity detector fixed to the end of the piston rod of the cylinder, and a probe arranged at the bottom of the bearing capacity detector. Two groups of symmetrically arranged lifting components are installed at the bottom of the mounting plate, and each group of the lifting components includes a sleeve fixed to the bottom of the mounting plate, a screw rod rotatably connected to the inner top wall of the sleeve, and a mounting rod sleeved on the screw rod and threadedly connected, the mounting rod is slidably connected to the inner wall of the sleeve, and a fixing plate is fixed to the lower ends of the two mounting rods. A through hole is opened on the fixing plate for the bearing capacity detector to pass through, a plurality of ground plugs are fixed to the bottom of the fixing plate, and a power component for driving the screw rod to rotate is installed on the sleeve.

[0007] By adopting the above technical solution, after the detection component is moved to the foundation position that needs to be detected by the roller, the staff drives the screw to rotate through the power component. Since the screw is threadedly connected to the mounting rod, and the mounting rod is slidingly connected to the inner wall of the sleeve, the mounting rod drives the fixing plate to move downward along the axial direction of the screw, so that the ground plug is inserted into the foundation, and then the bearing capacity is tested through the detection component, which reduces the probability of position deviation during the detection process and improves the stability of the foundation bearing capacity detection.

[0008] Furthermore, the power assembly includes a motor fixed to the side wall of the sleeve, the output shaft of the motor passes through the side wall of the sleeve and is rotatably connected, and the power assembly also includes a driving bevel gear fixed to the end of the output shaft of the motor and a driven bevel gear fixedly sleeved on the screw and meshing with the driving bevel gear.

[0012] Furthermore, a rubber sheet is fixed to the bottom of the fixing plate.

[0013] By adopting the above technical solution, the rubber sheet is made of rubber material, and its surface has a large friction coefficient. When the ground plug is fully inserted into the foundation, the fixing plate cooperates with the foundation and presses against the rubber sheet, which increases the friction between the fixing plate and the foundation and further enhances the stability during the foundation bearing capacity detection.

[0014] Furthermore, fixing rods are fixed to the side walls on both sides of the sleeve, and one end of the two fixing rods away from the sleeve is respectively fixed to the side walls of the supporting legs on both sides.

[0015] By adopting the above technical solution, the fixing rod connects the sleeve and the supporting leg, which supports and reinforces the sleeve and enhances the stability of the lifting assembly.

[0016] Furthermore, a handrail is fixed to the side wall of the mounting plate.

[0017] By adopting the above technical solution, the handrail provides a fulcrum for the mounting plate, making it convenient for workers to move the device through the handrail.

[0018] Furthermore, the side wall of the sleeve is provided with a protective shell for covering the motor.

[0019] By adopting the above technical solution, the protective shell protects the motor and reduces the probability of the motor being damaged under the action of external forces.

[0020] Furthermore, a controller electrically connected to the motor is arranged on the top of the mounting plate.

[0021] By adopting the above technical solution, the controller is connected to the motor, which makes it convenient for the staff to control the height of the fixing plate and the ground plug through the controller.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In this application, after the detection assembly is moved to the position of the foundation to be detected by the roller, the staff drives the screw to rotate through the power assembly. Since the screw is threadedly connected to the installation rod, and the installation rod is slidingly connected to the inner wall of the sleeve, the installation rod drives the fixing plate to move downward along the axial direction of the screw, so that the ground plug is inserted into the foundation, and then the bearing capacity is tested by the detection assembly, which reduces the probability of position deviation during the detection process and improves the stability of the foundation bearing capacity detection;

[0024] 2. In this application, when it is necessary to drive the screw to rotate, the staff only needs to start the motor to drive the active bevel gear to rotate, so that the driven bevel gear meshing with the active bevel gear and the screw fixed to the driven bevel gear rotate, so that the installation rod moves along the axial direction of the screw, which is convenient for inserting the ground plug into the foundation;

[0025] 3. In the present application, the rubber sheet is made of rubber material, and its surface has a large friction coefficient. When the ground plug is fully inserted into the foundation, the fixing plate cooperates with the foundation and presses against the rubber sheet, which increases the friction between the fixing plate and the foundation, and further enhances the stability during the foundation bearing capacity test.

[0034] The lifting assembly 5 is installed at the bottom of the mounting plate 1. The lifting assembly 5 is symmetrically arranged in two groups, and each group of lifting assembly 5 includes a sleeve 51, a screw 52 and a mounting rod 53. The sleeve 51 is a rectangular parallelepiped structure with an open bottom, and the sleeve 51 is fixed to the bottom of the mounting plate 1. The screw 52 is a vertically arranged rod-shaped structure, and the screw 52 is rotatably connected to the inner top wall of the sleeve 51.
