Description

Technical Field

[0001] The utility model belongs to the technical field of an anti-pulling detection device, and more specifically, particularly relates to an anti-pulling detection test device. Background Art

[0002] Pile foundation construction refers to the construction process of the foundation of a building. The pile foundation consists of piles and pile caps. The pile construction method is divided into two categories: precast piles and cast-in-place piles. After the pile foundation construction is completed, the strength of the pile foundation needs to be tested using a pull-out test device. The pull-out performance of the pile foundation is one of the necessary indicators in project acceptance. The device consists of a reaction beam, which uses the lifting force of the jack and a sensing element to detect the changing value of the pile column during the lifting process.

[0003] Based on the above, the inventors have discovered the following problems: most of the existing pull-out resistance testing devices are placed on uneven ground during pile foundation testing, and the device cannot be leveled in real time, which causes trouble to the staff. At the same time, the test device is transported as a whole during transportation, but due to its large size, it cannot be disassembled for transportation, which may cause inconvenience in movement and indirectly affect its subsequent use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a pull-out test device is provided to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effect of the pull-out test device of the utility model are achieved by the following specific technical means:

[0006] The cam is provided with a toothed structure, and the toothed structure ...

[0007] Furthermore, an anti-skid pad is connected and installed on the bottom end of the base plate.

[0008] Furthermore, a handle is connected and installed on one side outer wall of the base, and the output end of the handle passes through the base to the inside where a second bevel gear is fixedly installed, and the first bevel gear is meshed with the second bevel gear.

[0009] Furthermore, a set of buckles 2 are fixedly mounted on the top of the base, and the buckle 1 is engaged with the buckle 2.

[0010] Furthermore, the testing mechanism includes a jack, a connecting plate is installed on the top of the jack, and one end of the tensile steel bar passes through the cross beam and the connecting plate respectively.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] Through the cooperation between the handle, the first bevel gear and the second bevel gear, when installing the test device, the staff can first place it on the ground, and then use the handle to drive the second bevel gear, the first bevel gear and the threaded rod to rotate, so as to drive the slider and the frame to move, and the height of the bottom plate can be finely adjusted in real time, which is convenient for the staff to quickly level the device. The operation steps are very simple, and under the effect of the anti-slip pad, it can effectively prevent slipping and avoid shaking of the device during use, which indirectly improves the use efficiency of the device, and the design greatly increases the practicality.

[0013] Through the cooperation between buckle one and buckle two, when the staff needs to transport the device after using it, they can press the pressing block to drive buckle one to move, and then they can detach it from buckle two. Then the staff can disassemble the base, and the device can be effectively disassembled and transported to avoid the trouble caused by the large size to the staff. At the same time, when installing, they only need to install the base directly on the beam. Under the action of the spring, buckle one and buckle two can be engaged, so that the base can be limited and fixed, which indirectly brings convenience to the staff and increases transportation efficiency.
