Description

Technical Field

[0001] The utility model belongs to the technical field of load box detection, in particular to a load box detection device. Background Art

[0002] The load box is a pressure test unit or loading device in the self-balancing static load test of the pile foundation. It is pre-buried at the balance point of the pile body and loaded step by step through the load box to observe the displacement and obtain data at the same time, so as to draw the load settlement displacement and pull-out curves of the upper and lower pile bodies, so as to obtain the single pile vertical compressive ultimate bearing capacity of the test pile. When the load box is produced and processed, it is often necessary to test it to determine whether the bearing capacity of the load box meets the standard. In real life, when using a load box detection device to detect the load box, it is necessary to take the load box and place it on the movable table in the detection device. Since most detection devices are not equipped with an auxiliary pick-up and placement mechanism, the detection personnel are required to manually lift the load box. After a long time of detection, not only will the fatigue of the detection personnel increase, but also the detection efficiency will be affected.

[0003] A Chinese patent document (application publication number CN214844500U) discloses a load box detection device, which includes a base, a fixing frame fixedly installed on the top of the base, a reinforcing steel plate fixedly installed inside the top of the inner cavity of the fixing frame, a jack fixedly installed on the top of the base, a pressure sensor located outside the jack fixedly installed on the top of the base, the number of the jacks is four, and movable platforms are fixedly installed on the tops of the four jacks.

[0004] It can be seen that the patent document cited above also has the same problem. It lacks an auxiliary picking and placing mechanism. When picking up and placing the load box, it is necessary to manually lift the load box to the movable platform at the top of the jack or lift it down from the movable platform. This will not only increase the fatigue of the inspectors after a long period of inspection, but also affect the inspection efficiency. Utility Model Content
