Description

Technical Field

[0001] The utility model belongs to the field of engineering detection, and specifically relates to a pile bearing capacity testing device. Background Art

[0002] Existing piles are a common reinforcement method to improve the bearing capacity of building foundations and control settlement. It is essential to test the bearing capacity of piles. The common pile bearing capacity test is: place a jack on the top of the test pile, place a load-bearing device on the top of the jack, and pile a specific weight of counterweight cement blocks on the load-bearing device, and place a pier cement pile between the load-bearing device and the ground to support the load-bearing device and prevent it from tipping over.

[0003] The Chinese patent with publication number CN215330083U discloses a pile bearing capacity test device, including a first support frame, a second support frame, a crossbeam, a plurality of jacks, a protection hoop and a protection platform, wherein the protection hoop is clamped on the outer periphery of the top of the pile, the protection platform is arranged on the top surface of the protection hoop and fits with the top surface of the pile, the plurality of jacks are respectively installed above the protection platform, the crossbeam is arranged on the top of the plurality of jacks, the two ends of the crossbeam are respectively connected vertically with the first support frame and the second support frame, a weight block is arranged on the crossbeam, and the first support frame and the second support frame are both provided with a hydraulic cylinder. The pile bearing capacity test device provided by the utility model can protect the top of the pile through the protection hoop and the protection platform.

[0004] The above pile foundation bearing capacity test device connects the protection platform to the pile foundation through a protection hoop to perform a bearing capacity test. When the bearing capacity is too large, the protection hoop is prone to displacement and instability, resulting in a deviation in the bearing capacity of the pile foundation test.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0008] A pile bearing capacity testing device comprises a bearing platform, a protective cover is arranged at the bottom of the bearing platform, a pile is arranged at the bottom of the protective cover, and a stabilizing component is arranged between the bearing platform and the protective cover;

[0009] The stabilizing component comprises a moving block which is slidably matched inside the protective sleeve, a connecting frame arranged between the moving block and the bearing platform, a clamping plate is installed on one side of the moving block, and the clamping plate is located inside the protective sleeve.

[0010] Optionally, a plurality of fixed blocks are installed at the bottom of the bearing platform, and a first connecting column is installed on the fixed block, and connecting grooves are opened on opposite sides of the connecting frame, and the first connecting column is rotatably engaged in one of the connecting grooves, and a second connecting column is installed on the other side of the moving block, and the second connecting column is rotatably engaged in the other connecting groove. A fixed sleeve is installed at the bottom of the bearing platform, and the connecting frame is set at an acute angle to the bottom edge of the bearing platform near the fixed sleeve; by leaving a distance between the fixed sleeve set at the bottom of the bearing platform and the fixed axis of the protective sleeve, the up and down movement can be adjusted, and the protective sleeve is larger than the diameter of the foundation pile, and the protective sleeve is set on the foundation pile to protect its top, and the moving block is slidably engaged in the sliding groove of the protective sleeve through a slider, so that when a heavy object is placed on the bearing platform for a bearing capacity test, the bearing platform will move downward through the plurality of connecting frames to drive the plurality of moving blocks to move. Because the connecting frame is set at an acute angle to the bottom edge of the bearing platform near the fixed sleeve, the splint on the moving block can clamp and fix the foundation pile.

[0011] Optionally, a fixed shaft is installed on the protective sleeve, the fixed sleeve is connected to the fixed shaft, a slider is installed on the movable block, a plurality of through grooves are opened on the protective sleeve, the movable block slides in the through grooves, a plurality of sliding grooves are opened in the protective sleeve, and the slider slides in the sliding grooves.

[0012] Optionally, a threaded sleeve is installed on one side of the fixing sleeve, and the inner thread of the threaded sleeve is equipped with a fixing bolt, and the fixing bolt and the fixing sleeve are interference fit to abut on the fixed shaft; by setting the threaded sleeve in the fixing sleeve, the inner thread of the threaded sleeve is equipped with a fixing bolt, and when the fixing bolt is rotated to abut against the fixed shaft in the fixing sleeve, it plays a fixing role, so that the pile bearing capacity testing device ensures the stability between the bearing platform and the protective sleeve when not in use.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0014] The pile bearing capacity testing device can be adjusted up and down by leaving a distance between a fixed sleeve arranged at the bottom of the bearing platform and the fixed axis of the protective sleeve. The protective sleeve is larger than the diameter of the pile. The protective sleeve is arranged on the pile to protect the top of the pile. The moving block is slidably engaged in the sliding groove of the protective sleeve through a slider, so that when a heavy object is placed on the bearing platform for bearing capacity testing, the bearing platform will move downward through multiple connecting frames to drive multiple moving blocks to move. Because the connecting frame is arranged at an acute angle to the bottom edge of the bearing platform close to the fixed sleeve, the clamping plate on the moving block can clamp and fix the pile. The more heavy objects on the bearing platform, the greater the clamping force of the clamping plate on the pile, thereby ensuring that the pile bearing capacity testing device has a certain stability when testing piles of different sizes and thicknesses.
