Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective support technology, specifically to a movable rotating support mechanism. Background Technology
[0002] In large industrial facilities and special scenarios, such as large hangar protective doors with openings up to 25 meters wide and 7 meters high, as well as flood control dikes and military roadblocks, the supporting structures must meet multiple functional requirements. On the one hand, when the door is fully open, the supporting structure must be able to lie flat, keeping the upper surface level with the foundation surface, ensuring that heavy equipment such as aircraft and vehicles can pass through smoothly. On the other hand, when the door is closed, the supporting structure must press firmly against the lower edge of the door from the back, effectively transferring the shock wave load borne by the front of the door, ensuring the stability and safety of the overall structure.
[0003] In existing technologies, traditional support mechanisms often suffer from complex structural designs and insufficient operational flexibility. Most support mechanisms rely on a single drive method, making manual operation difficult in emergency situations such as power outages, resulting in doors failing to open promptly and impacting equipment access or emergency response efficiency. Furthermore, some support mechanisms suffer from inappropriate material selection and welding processes, making them prone to deformation and damage due to excessive loads or prolonged use, failing to meet the high strength and reliability requirements of support structures in scenarios such as large hangars and flood control dams. Moreover, traditional mechanisms have poor buffering performance, easily generating severe impacts during movement, which not only affects the equipment's lifespan but may also cause additional damage to the doors and foundation structure.
[0004] Therefore, in response to the specific needs of the above scenarios, developing a movable rotating support mechanism that combines automatic and manual operation functions, has high structural strength, good buffering performance, and can adapt to multiple working conditions has become an urgent technical problem to be solved in this field.

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0031] Example 1:
[0032] like Figures 1-4 and Figures 8-11 As shown, this embodiment adopts the following technical solution: It includes a rotating support structure 1, a pre-embedded base 2, a rotating hinge seat 3, a rotating electric actuator 6, and a buffer device 7; the pre-embedded base 2 is installed in a pit, the rotating hinge seat 3 is installed on the pre-embedded base 2, and several reinforcing ribs 11 are installed between the rear side of the rotating hinge seat 3 and the pre-embedded base 2 to increase the stability of the rotating hinge seat 3. The rotating support structure 1 is rotatably connected to it. The upper panel of the rotating support structure 1 is made of Q355B checkered plate (12mm thick), and the remaining parts are made of Q235B (20mm and 10mm thick) steel plate as stiffeners, and are welded as a whole; a pin connecting seat 21 is installed on the upper panel of the rotating support structure 1. The output end of the rotary electric actuator 6 is movably connected to the pin connecting seat 21 via a connecting pin. The upper part of the rotary electric actuator 6 is rotatably mounted on the drive hinge seat 20 fixed to the side wall. The bottom of the drive hinge seat 20 is rotatably connected to the buffer device 7. The movable end of the buffer device 7 is rotatably connected to the pin connecting seat 21. The buffer device 7 is a damper that can play a buffering role during the closing or opening of the rotary support structure 1. Several front support seats 5 and several rear support seats 4 are fixed on the front and rear sides of the pre-embedded base 2, respectively. A buffer base plate 19 is fixed on the front side of the bottom of the rotary support structure 1. The buffer base plate 19 is mounted on the front support seat 5, and the bottom side of the rotary support structure 1 is mounted on the rear support seat 4.
[0033] The upper part of the front sidewall of the pit is equipped with a front inclined embedded part 8, and the upper part of the front inclined embedded part 8 is equipped with a front panel 9 with a right angle structure; the top of the rotating hinge seat 3 is integrally formed with a rear panel 10, the upper part of the rear panel 10 has a bent structure, and the upper surface of the bent edge, the upper surface of the front panel 9 and the upper surface of the upper plate of the horizontal rotating support structure 1 are all flush.
[0034] The top plate of the rotating support structure 1 has four clearance holes 1-1, of which the rightmost clearance hole 1-1 is a rectangular structure with a notch, and the other clearance holes 1-1 are arc-shaped. A matching top plate 14 is installed in the clearance hole 1-1. The top plate 14 has a socket 14-1. The top plate 14 is installed on the top of the side plate 13, and the upper surface of the top plate 14 is flush with the upper surface of the front panel 9. The side plate 13 is fixed to the rear wall of the pit by several front horizontal embedded parts 12. The output ends of several door locking electric push rods 15 installed on the back of the door leaf 16 are movably inserted into the socket 14-1. The top plate of the rotating support structure 1 has several inspection ports, and each inspection port is equipped with an inspection cover 18.
[0035] Example 2:
[0036] See Figures 6-7 In this embodiment, the top plate of the rotating support structure 1 is hinged with four cover plates 17 by several hinges. There is a notch on the rear side of the socket 14-1, which is used to allow the hinges to make way. The four cover plates 17 are respectively installed to cover the four sockets 14-1. When the rotating support structure 1 is in the closed state, the cover plates 17 can cover the sockets 14-1 to ensure the overall flatness and facilitate the passage of equipment. When it is in the state of pressing against the door leaf, the cover plates 17 are folded vertically to the ground and abut against the back of the door leaf 16 to increase the contact area.
[0037] In use, when the door leaf 16 is fully open, the opening and closing of the rotating support structure 1 is controlled by rotating the electric push rod 6. When closed (e.g.) Figure 1 and Figure 7 As shown), at this time, its upper surface, the upper surface of the bent edge, the upper surface of the front panel 9, and the ground are all on the same plane, and the equipment can pass on it; when it is necessary to close the door 16, the rotating support structure 1 is first opened by rotating the electric push rod 6 (as shown). Figure 2 and Figure 6 (As shown), then close the door leaf 16. After it is closed, the output end of the door locking electric push rod 15 passes over the clearance hole 1-1 and is inserted into the socket 14-1. At this time, the back of the door leaf 16 abuts against the side of the rotating support structure 1. The rotating support structure 1 plays a certain pressing role on the bottom of the back of the door leaf 16, transmitting the shock wave load received from the front of the door leaf.
[0038] When the power is off, lock the buffer device 7, then manually pull out the connecting pin between the rotating electric push rod 6 and the pin connecting seat 21, so that the rotating electric push rod 6 is disengaged from the rotating support structure 1. Then manually and slowly release the locking structure of the buffer device 7, so that the rotating support structure 1 slowly descends, thus achieving the manual opening function.
[0039] Compared with the prior art, the beneficial effects of this utility model are:
[0040] When the rotating support structure is in a horizontal position, it can ensure that heavy equipment such as aircraft and vehicles can pass smoothly.
[0041] When the rotating support structure is opened, it can support the heavy door leaf, effectively transfer the shock wave load on the front of the door leaf, and ensure the stability and safety of the overall structure.
[0042] Manual operation is enabled in emergency situations such as power outages to ensure the door can be opened normally, allowing the equipment to pass through normally or respond to emergencies, thus adapting to the needs of multiple operating conditions.
[0043] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
