Description

Technical Field

[0001] The utility model relates to the technical field of concrete slab detection, in particular to an efficient concrete slab detection device. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of cementitious materials that bind aggregates together. It is widely used in construction projects, but in building structures, the hardness of concrete is particularly important. Only by ensuring the hardness of concrete can the building structure be guaranteed to be firm, thereby extending the service life of the building structure. Therefore, it is necessary to test the hardness of concrete before using it.

[0003] The existing concrete block detection device mainly counterweights the detection rod through a counterweight block, and makes the detection rod fall freely for detection. Therefore, the staff is required to move the counterweight block to a high place for fixing, which makes the workload large and the work efficiency low. Moreover, the mass of the counterweight block is generally fixed, and the counterweight cannot be adjusted according to the detection requirements of different concrete slabs, which may lead to failure to meet the counterweight requirements of the detection. When the counterweight is too large, the concrete slab is easily smashed through, thereby affecting the detection work. Therefore, it is necessary to propose an efficient concrete slab detection device to solve the above-mentioned problems. Summary of the invention

[0007] In order to improve the stability of the lifting plate, as a preferred embodiment of an efficient concrete slab detection device of the utility model, four sliding rods are fixedly connected to the upper end of the workbench, and the four sliding rods penetrate the lifting plate and are slidably connected thereto.

[0008] In order to improve the smoothness of the movement of the two support rollers on the same side, as a preferred efficient concrete slab detection device of the utility model, the inner walls of the four support rollers are fixedly connected with a rotating shaft, and the front and rear ends of the two rotating shafts on the same side are respectively rotatably connected to the front and rear sides of the inner walls of the two U-shaped frames.

[0009] In order to improve the stability of the movement of the two moving blocks, as a preferred embodiment of an efficient concrete slab detection device of the utility model, the two moving blocks are respectively slidably connected to the left and right sides of the upper end surface of the workbench through slide rails.

[0013] A counterweight is fixed to the upper side of the mounting plate, and multiple counterweights can be stacked from bottom to top in sequence by means of threaded connection. The size and mass of each counterweight can be selected and combined as required, so as to facilitate the adjustment of the counterweight according to the inspection requirements of different concrete slabs, so as to avoid the concrete slab failing to meet the inspection requirements due to too small counterweight or breaking through the concrete slab due to too large counterweight during inspection.

[0014] The two L-shaped support plates are lifted up by two hydraulic cylinders respectively, and the lifting plate, detection rod, counterweight and mounting plate are driven to move upward at the same time, and then the two support rollers on the same side are separated from the two L-shaped support plates, so that the detection rod slides downward with the action of the counterweight, and the concrete slab is impact-tested by the detection rod.
