Description

Technical Field

[0001] The utility model relates to the technical field of component detection, in particular to a PC floor component strength detection device. Background Art

[0002] Precast concrete components are building components made in factories with concrete and steel bars as basic materials, including beams, plates, columns, floor slabs and building decoration accessories. After the floor slabs are made, their surface compressive resistance needs to be tested to detect the quality of the precast floor slab components.

[0003] However, existing prefabricated concrete floor components have the following difficulties in the process of bearing pressure testing: the prefabricated floor components need to be manually fixed during the test to avoid damage to the prefabricated components due to unreliable fixation during the pressure test, thereby affecting the test of the compressive capacity of the prefabricated floor components made of reinforced concrete, and the operations of fixing and disassembling the floor components are complicated and time-consuming, which affects the efficiency of the test. Utility Model Content

The lifting platform is lowered to drive the ball bearings to descend, and the floor slab falls on the surface of the supporting plate, and the positioning is completely completed under the fixation of the limit frame, and then the lower pressure head continues to press down. At this time, the hydraulic cylinder drives the limit frame to be retracted synchronously to carry out the downward pressure test. After the test is completed, the lower pressure piece rises and moves through the movement of the pull rope, and the movable piece is reset through the guidance of the fixed pulley. Then the floor slab is taken out and the next floor slab is re-tested. Through the setting of the lifting platform and the ball bearings, the position of the floor slab can be quickly adjusted in cooperation with the limit frame, so that its placement position is more accurate and the error caused by offset is prevented. The moving part can be assisted to move by the assistance of the pull rope and the connecting frame. The floor slab can be limited by extending the limit frame above the moving part for a short distance.

[0006] As a further solution of the utility model: the inner cavity of the support base is fixedly connected with a reinforcing rod, and the inner cavity of the lifting platform is provided with a through groove adapted to the surface of the reinforcing rod. The reinforcing rod supports the support base without interfering with the lifting of the lifting platform, thereby increasing its compressive strength.

[0007] As a further solution of the utility model: one side of the lower pressure piece is fixedly connected to a connecting frame, the bottom of the connecting frame is fixedly connected to a push plate, the surface of the push plate is provided with an inclined surface parallel to the surface of the limit frame, and through the setting of the push plate, the push plate can be pushed to move through the connecting frame when the lower pressure piece moves downward, driving the movable part to move toward the floor on the supporting base.

[0008] As a further solution of the utility model: the surface of the support plate is rotatably connected to a fixed pulley, and the bottom of the connecting frame is fixedly connected to a pull rope which is transmission-connected to the surface of the fixed pulley, one end of the pull rope is fixedly connected to one side of the moving part, and through the setting of the pull rope, when the lower pressure part is raised, the movement of the pull rope pulls the moving part to its reset position through the guidance of the fixed pulley, thereby canceling the limit on the floor slab.

[0009] As a further solution of the utility model: two connecting frames are provided, and are symmetrically arranged on both sides of the center position of the supporting base.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The utility model can quickly adjust the position of the floor slab by setting the lifting platform and the ball bearings in cooperation with the limit frame, so that the placement position is more accurate and the error caused by the offset is prevented. The moving part can be assisted to move by the help of the pull rope and the connecting frame. The floor slab can be limited by extending the limit frame above the moving part for a short distance.

[0012] 2. The utility model adopts the setting of the push plate, which can push the push plate to move through the connecting frame when the lower pressure piece moves downward, thereby driving the movable piece to move toward the floor on the supporting base. The setting of the pull rope can pull the movable piece to reset through the movement of the pull rope when the lower pressure piece rises, thereby canceling the limit on the floor.
