Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door-turning devices, in particular to a door-turning device and a load-bearing square cabin. Background Art
[0002] The doors of existing shelters are mostly passages for personnel or equipment to enter and exit. The function of the doors is more as a passage for equipment maintenance or staff. There are not many requirements for the structural strength of the doors in terms of load-bearing capacity. Therefore, the shelters used for loading and transfer mainly have requirements for the load-bearing capacity of the cabin body, but no requirements for the doors.
[0003] In recent years, some small-sized vehicle-carrying equipment needs to be moved. In order to efficiently transport them, multiple devices are generally transported by loading them into a container. Since small-sized vehicle-carrying equipment is relatively heavy, it is often necessary to use lifting equipment to load it into the container. Due to the limitations of external force or manual methods, loading is time-consuming, labor-intensive, and inefficient. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a flap device and a load-bearing square cabin, which can improve the efficiency of loading small vehicle-carrying equipment in the square cabin.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0006] In a first aspect, the present invention provides a door-turning device.
[0007] A door-turning device comprises: a cabin door frame, two door-turning rotating parts respectively mounted on the upper and lower sides of the cabin door frame, and a cabin upper door and a cabin lower door respectively mounted on the two door-turning rotating parts;
[0008] An upper abutment plate is installed at the free end of the upper flip door of the square cabin, and a lower abutment plate is installed at the free end of the lower flip door of the square cabin. A long groove is provided on the upper abutment plate, and a sealing strip is installed in the long groove. When the cabin door is closed, the free end of the upper flip door of the square cabin and the free end of the lower flip door of the square cabin are close to each other. When the cabin door is closed, the sealing strip abuts against the lower abutment plate.
[0009] By adopting the above technical solution, when loading small vehicle carriers, the upper cabin door is first flipped up using the flap rotating member on the upper side of the cabin door frame, and then the lower cabin door is flipped down using the flap rotating member on the lower side of the cabin door frame. During this process, the cabin is open, the lower abutment plate abuts the ground, and the long block is located between the lower abutment plate and the ground to reduce the vibration caused by people stepping on the lower abutment plate and the lower cabin door. Then, the staff can load the small vehicle carrier into the cabin. The flap facilitates staff entry and exit and increases the space for entry and exit, thereby improving the efficiency of loading small vehicle carriers into the cabin. After loading, the flap rotating member on the lower side of the cabin door frame flips the lower cabin door up, and the flap rotating member on the upper side of the cabin door frame flips the upper cabin door down. At this time, the sealing strip abuts the lower abutment plate, effectively reducing the possibility of rainwater erosion into the cabin.
[0010] Optionally, the cross-section of the lower abutment plate away from one end of the cabin lower flip door is inclined.
[0011] By adopting the above technical solution, when the lower flip door of the cabin is opened, there is a certain distance between the end of the lower flip door close to the cabin door frame and the ground, so the end of the lower flip door away from the cabin door frame is facing the ground. Therefore, setting the cross-section of the lower abutment plate away from the end of the lower flip door of the cabin to be inclined can improve the fit with the ground.
[0012] Optionally, a door-opening device further includes: an upper door opening and closing assist member and a lower door opening and closing assist member; the two ends of the upper door opening and closing assist member are respectively rotatably arranged on the cabin door frame and the upper door of the cabin, and the two ends of the lower door opening and closing assist member are respectively rotatably arranged on the cabin door frame and the lower door of the cabin, and both the upper door opening and closing assist member and the lower door opening and closing assist member can be extended and retracted in length.
[0013] By adopting the above technical solution, the upper door opening and closing assisting member and the lower door opening and closing assisting member can be extended and retracted in length, so as to apply force to the opening and closing of the upper door and the lower door of the cabin respectively, so as to achieve the purpose of assisting, and thus can effectively improve the opening and closing rate of the upper door and the lower door of the cabin.
[0014] Optionally, at least one upward-flip door locking member is provided on the upward-flip door of the shelter, and the upward-flip door locking member is used to lock the upward-flip door to the shelter door frame.
[0015] By adopting the above technical solution, when the cabin upward flip door is closed, the upward flip door locking member can lock the cabin upward flip door to the cabin door frame, thereby reducing the opening and closing of the cabin upward flip door due to shaking.
[0016] Optionally, at least one downward-flip door locking member is provided on the downward-flip door of the shelter, and the downward-flip door locking member is used to lock the downward-flip door to the cabin door frame.
[0017] By adopting the above technical solution, when the cabin lower flip door is closed, the lower flip door locking member can lock the cabin lower flip door to the cabin door frame, thereby reducing the opening and closing of the cabin lower flip door due to shaking.
[0018] Optionally, a flap sealing strip is installed on the inner edge of the cabin door frame.
[0019] By adopting the above technical solution, the flap sealing strip can seal the gap between the cabin door frame and the two flaps, thereby improving the waterproof effect between the cabin door frame and the two flaps, and further reducing the possibility of rainwater entering the cabin.
[0020] Optionally, a power-assisting handle is installed on the upward flip door of the cabin.
[0021] By adopting the above technical solution, the power-assisting handle can provide a force application point for the staff, so that the staff can apply force to the upward flip door of the cabin.
[0022] In a second aspect, the utility model provides a load-bearing square cabin.
[0023] A load-bearing shelter comprises a door-turning device as described in any one of the first aspects.
[0024] By adopting the above technical solution and arranging a flap device on the load-bearing square cabin, the efficiency of loading small vehicle-carrying equipment in the square cabin can be improved.
[0025] In summary, the present invention has at least the following beneficial technical effects:
[0026] 1. By installing a flap device on the cabin, it is easier for staff to enter and exit the cabin, and the space for entry and exit is expanded, thereby improving the efficiency of loading small-sized vehicle equipment in the cabin. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] This embodiment provides a door-turning device and a load-bearing shelter.
[0034] refer to Figure 1 and Figure 3 A flip door device includes a cabin door frame 1, a cabin upper flip door 2, a cabin lower flip door 3, an upper flip door locking part 4, a lower flip door locking part 5, an upper flip door opening and closing assisting part 6, a lower flip door opening and closing assisting part 7, a flip door sealing strip 8 and two flip door rotating parts 9.
[0035] The shelter door frame 1 is mounted on one side of the shelter to form a shelter door. One flap rotating member 9 is mounted on one side of the upper edge of the shelter door frame 1, and the other flap rotating member 9 is mounted on one side of the lower edge of the shelter door frame 1. The shelter upper flap door 2 is mounted on the flap rotating member 9 on the upper edge of the shelter door frame 1, and the shelter lower flap door 3 is mounted on the flap rotating member 9 on the lower edge of the shelter door frame 1. When the two flap rotating members 9 rotate, they can control the opening and closing of the shelter upper flap door 2 and the shelter lower flap door 3.
[0036] In the embodiment of the present application, the door rotating member 9 is a gear rod combination, and the lower cabin door 3 and the upper cabin door 2 are respectively fixedly connected to the two rotating shafts of the two rotating motors. In other embodiments, the door rotating member 9 can also be a rotating motor.
[0037] refer to Figure 1 、 Figure 2 and Figure 3 An upper abutment plate 10 is mounted on the free end of the upper enclosure door 2, which is the end of the upper enclosure door 2 that is distal to the attached flap rotating member 9. A lower abutment plate 11 is mounted on the free end of the lower enclosure door 3, which is distal to the attached flap rotating member 9. An elongated groove 12 is defined in the upper abutment plate 10, within which a sealing strip is mounted.
[0038] When the cabin door is open, the free ends of the upper and lower doors 2 and 3 move away from each other. When the cabin door is closed, the free ends of the upper and lower doors 2 and 3 move toward each other. When the cabin door is closed, the sealing strip abuts against the lower abutment plate 11, thereby enhancing the waterproofing between the upper and lower doors 2 and 3.
[0039] At the same time, the cross section of the lower abutting plate 11 away from the lower flip door 3 of the cabin is inclined, so that the lower abutting plate 11 can better abut against the ground, thereby improving the stability of the lower abutting plate 11 and the lower flip door 3 of the cabin.
[0040] refer to Figure 1 and Figure 3 One end of the upward door opening and closing assist member 6 is pivotally connected to the shelter door frame 1, and the other end is pivotally connected to the shelter upward door 2. When the shelter upward door 2 is opened, the upward door opening and closing assist member 6 lengthens; when the shelter upward door 2 is closed, the upward door opening and closing assist member 6 shortens. The upward door opening and closing assist member 6 is able to adaptively rotate during this length change. The upward door opening and closing assist member 6 is used to assist the opening and closing of the upward door, thereby improving the convenience of opening and closing the upward door.
[0041] One end of the lower door opening and closing assist member 7 is pivotally connected to the shelter door frame 1, and the other end is pivotally connected to the shelter lower door 3. When the shelter lower door 3 is opened, the lower door opening and closing assist member 7 lengthens; when the shelter lower door 3 is closed, the lower door opening and closing assist member 7 shortens. This lengthening process allows the lower door opening and closing assist member 7 to adaptively rotate. The lower door opening and closing assist member 7 assists in opening and closing the lower door, enhancing its ease of operation.
[0042] In the embodiment of the present application, the upper door opening and closing assisting member 6 and the lower door opening and closing assisting member 7 are both telescopic rods. In other embodiments, the upper door opening and closing assisting member and the lower door opening and closing assisting member 7 can also be telescopic cylinders, hydraulic cylinders or electric push cylinders.
[0043] The upper door locking member 4 is mounted on the upper cabin door 2, and the lower door locking member 5 is mounted on the lower cabin door 3. The upper door locking member 4 and the lower door locking member 5 are respectively used to lock the upper cabin door 2 and the lower cabin door 3 to the cabin door frame 1. In the embodiment of the present application, both the upper door locking member 4 and the lower door locking member 5 are implemented as lock buckles, and two of each are implemented. In other embodiments, the upper door locking member 4 and the lower door locking member 5 may be implemented as other locking components, or in other numbers.
[0044] The flap sealing strip 8 is embedded in the inner edge of the cabin door frame 1 to seal the gap between the cabin door frame 1 and the cabin flap, improving the waterproof effect of the cabin after the cabin door is closed. At the same time, the cabin upper flap 2 is also equipped with a grip handle to facilitate the staff to apply force to the cabin upper flap 2.
[0045] A load-bearing shelter includes the aforementioned door-turning device. The door-turning device is arranged on the shelter of the load-bearing shelter. Since the door-turning device has been described in detail above, it will not be described again here.
