TECHNICAL FIELD

[0001] The application relates to the technical field of handling devices, in particular to an underground heavy hydraulic turnover plate. BACKGROUND

[0002] The underground heavy hydraulic turnover plate is widely used in the fields of logistics and warehousing, and performs excellently in handling the loading and unloading operations of large cargos. Such equipment sets the turnover plate table below the ground and uses a hydraulic system to realize the lifting and tilting of the turnover plate table, significantly improving the efficiency and safety of cargo loading and unloading. With the rapid development of the logistics industry, the demand for underground heavy hydraulic turnover plates is increasing, and they have become an important tool for improving the operation efficiency of the logistics system.

[0003] However, the existing technical means have a problem in actual use, that is, due to the accumulation of cargos and the large size of the turnover plate table, it is difficult for the operator to accurately judge the tilting angle of the turnover plate table by visual observation. This not only affects the unloading efficiency of the cargos, but also may cause operational errors and increase safety hazards. Therefore, how to accurately detect the tilting angle of the turnover plate table in a complex working environment has become a technical problem to be solved in this field. CONTENT OF THE INVENTION

[0004] In order to overcome the above technical problems, the application provides an underground heavy hydraulic turnover plate.

[0005] The underground heavy hydraulic turnover plate provided by the application adopts the following technical scheme:

[0006] An underground heavy hydraulic turnover plate comprises a foundation pit, a turnover plate table, a support assembly, an opening detection mechanism and a hydraulic jacking device arranged in the foundation pit;

[0007] The hydraulic jacking device is hingedly connected to the bottom of the turnover plate table;

[0008] The support assembly comprises a fixed frame, the fixed frame is arranged in an L-shaped frame body, and the fixed frame comprises a fixed end and a bearing end;

[0009] The opening detection mechanism comprises a sliding column fixed on the fixed end, the sliding column is arranged at the middle position of the fixed frame along the length direction of the fixed frame, a sliding block is slidingly arranged on the sliding column, a linkage rod is hingedly connected to the bottom of the turnover plate table, and one end of the linkage rod away from the turnover plate table is hingedly connected to the sliding block;

[0010] A push plate is fixedly arranged on the top of the sliding block, and a pull rod is fixedly arranged on the push plate;

[0011] A sliding ring and a probe rod are fixedly arranged on one end of the pull rod away from the push plate, and the sliding ring is annular;

[0012] The opening degree detection mechanism further comprises a detector fixedly arranged on the fixed frame, the detector comprising a base, an annular groove being formed on the base to form a sealing ring groove, the sealing ring groove being provided with a first sealing ring groove and a second sealing ring groove of different sizes on the same side of the base, the detector further comprising a first partition shell and a second partition shell, the first partition shell and the second partition shell being fixedly arranged in the first sealing ring groove and the second sealing ring groove, respectively.

[0014] A sealing cover is fixedly arranged at the end of the second partition shell away from the base, the sealing cover being provided with a clearance hole for the probe rod to slide.

[0015] By adopting the above technical scheme, the tilt angle of the underground heavy hydraulic flip table can be accurately detected. Specifically, the cooperation of the slide column and the slide block enables the tilting action of the flip table to be converted into the sliding of the slide block along the slide column, thereby converting mechanical movement into measurable displacement change. The design of the linkage rod ensures that the sliding of the slide block is synchronized with the tilt angle of the flip table, improving the accuracy and real-time performance of the detection. The structural design of the push plate and the pull rod enables the sliding ring to move accordingly with the movement of the slide block, further transmitting mechanical movement. The multi-layer sealing design of the sealing ring groove and the partition shell effectively prevents the influence of the external environment on the inside of the detector, ensuring the stability and reliability of the detection. The contact design of the lead wire coil and the conductive block enables the conversion of mechanical displacement into electrical signals, facilitating subsequent signal processing and integration of the monitoring system. The clearance hole on the sealing cover allows the probe rod to slide freely while maintaining good sealing performance, ensuring the normal operation of the entire detection mechanism. This technical scheme not only solves the problem of accurately determining the tilt angle of the flip table in the prior art, but also improves the detection accuracy and stability, which helps the operator to perform the cargo unloading operation more safely and efficiently.

By adopting the above technical scheme, the bottom of the fixed end is fixedly arranged on the bottom wall of the foundation pit, and the bearing end extends vertically upward relative to the bottom wall of the foundation pit, so that the fixed frame can stably support the flip table top, and the stability of the structure is ensured. The bearing end is fixedly connected with the hinge shaft, and the hinge shaft is connected with the flip table top through the hinge, so that the flip table top rotates around the hinge shaft as the rotation center, the stable lifting of the flip table top is realized, and the operation reliability and safety of the equipment are improved.

[0020] By adopting the above technical scheme, the reset bearing beam can effectively support the weight of the flip table top in the initial position, and avoid structural deformation or damage caused by long-term use. At the same time, the pressure sensor arranged in the sensor groove on the reset bearing beam can monitor the state of the flip table top in real time, and when the flip table top is reset to the position, the pressure sensor will send a signal, so that the flip table top is accurately reset, and the safety and reliability of the equipment are improved.

[0021] Preferably, a pressure trigger block is fixedly arranged at the position corresponding to the sensor groove at the bottom of the flip table top.

[0023] Preferably, a first bearing pier is fixedly arranged at the bottom of the foundation pit, a clamping groove is formed in the top of the first bearing pier, and the hinge shaft is arranged in the clamping groove.

[0024] By adopting the above technical scheme, the stability and reliability of the flip table top can be effectively improved. Specifically, the arrangement of the first bearing pier enables the hinge shaft to be fixedly arranged in the clamping groove, so that the flip table top does not deviate or fall off during the turning process, and the structural stability of the whole system is enhanced. At the same time, this design can also reduce wear caused by long-term use, and prolong the service life of the equipment.

[0025] Preferably, a second bearing pier is also fixedly arranged at the bottom of the foundation pit, and the hydraulic jacking device is hingedly arranged at the top of the second bearing pier.

[0026] By adopting the technical scheme, the hydraulic jacking device is hingedly arranged at the top of the second load-bearing pier, so that the installation of the hydraulic jacking device is more stable, the stability and safety of the flip plate table top during lifting are improved, and the failure rate caused by equipment vibration or uneven stress is reduced.

This not only enhances the safety of the equipment, but also prolongs the service life of the equipment.

[0028] In summary, the present application has at least one of the following beneficial technical effects:

[0029] 1.
