Description

Technical Field

[0001] This utility model relates to the field of modular hospital technology, specifically to a modular hospital hatch flipping mechanism. Background Technology

[0002] A modular shelter is a box-shaped work area that is constructed by organically combining various sturdy materials. Its volume is fixed or expandable and it has protective properties, making it suitable for transportation. Common modular shelters include shipping containers, container houses, special-purpose carriages, medical modular shelters, military modular shelters, meteorological modular shelters, communication modular shelters, and mobile prefabricated houses, and they are widely used.

[0003] For weather shelters and similar equipment, such as radar, the top of the shelter needs to be unobstructed during operation. Therefore, the shelter cover is generally designed to open from the top. However, existing top-opening shelters often lack smoothness during the opening process. When the cover is close to the shelter body, the drive motor is subjected to a large torque, which can cause the drive motor to overload, affecting its service life and the stable operation of the shelter equipment.

[0004] Therefore, this utility model proposes a container hatch flipping mechanism, which can effectively reduce the torque of the drive motor during the flipping process, ensuring the service life of the motor and the stable use of the equipment. Utility Model Content

[0033] In the embodiment, the motor is a servo motor, and the speed reducer is a double-shaft output right-angle speed reducer.

[0034] In the embodiment, the servo motor and the double-shaft output right-angle speed reducer are connected in a bevel gear set reversing transmission mode to reduce the extension size of the tail of the vehicle body.

[0035] In the embodiment, the first connecting rod 313 is hingedly connected with the middle position of the cabin cover 2, and the second connecting rod 314 is hingedly connected with the position of the front end quarter of the cabin cover 2.

[0036] In another embodiment of the utility model, each of the both side plates of cabin body 1 is provided with a support mechanism 32, each support mechanism 32 includes a mounting seat 321, the mounting seat 321 is in an L shape, the front end of the mounting seat 321 is hingedly connected with a support rod 322, a spring 323 is arranged between the middle portion of the support rod 322 and the tail of the mounting seat 321, and a support portion 324 is arranged above the support rod 322.

[0039] The utility model principle is:

[0040] In the process of use, the utility model can open the top-opening cabin cover 2 to overturn and effectively ensure the stability of the cabin cover 2 in the process of overturning.

[0041] Now taking the hatch cover 2 closed state as the starting, the use principle of the utility model is explained.

[0042] Firstly, the operator controls the locking mechanism 33 to separate from the locking part 21, wherein, for the electric push rod 331, the operator can control by the controller, in the process, the push rod part 332 of the electric push rod 331 is retracted and separated from the slot 211, so that the cover opening operation can be carried out; in the process, the electric push rod 331 and its control action are involved, wherein the electric push rod 331 is existing, and its control is also existing mature technology, including wired control and wireless control, etc., the principle involved in the process is relatively simple, and it is not difficult for those skilled in the art to understand, so it will not be repeated.

[0043] Then, the motor reducer 311 acts and drives the hatch cover 2 to be lifted upward, in the process, since the hatch cover 2, the cabin body 1, the first connecting rod 313 and the second connecting rod 314 form a parallelogram structure, at this time the hatch cover 2 is stably lifted in a horizontal state, in the process the supporting mechanism 32 plays a supporting role, which can reduce the torque of the motor reducer 311, ensure the stability and service life of the transmission mechanism 31.

[0044] When the hatch cover 2 is horizontally lifted to the highest position, continue to turn over, then turn over to the rear in an arc shape, and finally turn over to the vertical state.

[0045] The process of closing the hatch cover 2 is similar to the above, and will not be repeated, it should be noted that when the hatch cover 2 is turned to horizontal and continues to turn over, the second connecting rod 314 cooperates with the supporting mechanism 32, at this time the supporting structure plays a buffering role, and can also provide a certain supporting force, avoiding the torque of the transmission mechanism 31 being too large, ensuring the stable turning over and the service life of the motor.
