Description

Technical Field

[0001] This utility model relates to the field of civil defense equipment technology, specifically a large civil defense door placement frame. Background Technology

[0002] In civil defense engineering construction, large civil defense doors serve as crucial protective facilities, and their quality and protective performance are of paramount importance. During the production, transportation, handling, and storage of large civil defense doors, proper placement is essential. However, current placement methods present numerous problems.

[0003] On the one hand, when encountering air-raid shelter doors of different sizes, it is difficult to find a suitable placement angle and height, resulting in unstable placement of the doors and potential safety hazards such as slippage and tipping. This could not only damage the doors but also threaten surrounding personnel and equipment. On the other hand, existing placement racks lack effective design in terms of bottom limiting and overall fixation. During placement, the bottom of the air-raid shelter door is prone to displacement, especially when subjected to external impacts or shaking during transport, which can easily lead to positional shifts, affecting subsequent operations and management.

[0004] In view of this, in order to solve the problems of poor stability and low versatility in the existing large-scale civil defense door placement process, we propose a large-scale civil defense door placement frame. Utility Model Content

The piston rods of the two hydraulic cylinders are hinged to the left outer wall of the diagonal brace. The diagonal brace includes an outer frame as the main body. Several vertically parallel support rods are fixedly installed inside the outer frame. A vertically movable crossbeam is provided at the top of the diagonal brace. A first motor is fixedly installed at both ends of the crossbeam. A first threaded rod is coaxially fixed to the output shaft of each first motor and is threadedly connected to the outer frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A large air-raid shelter door placement frame includes a base 1. A diagonal brace 3 is hinged to the top right side of the base 1, and two hydraulic cylinders 2 are symmetrically hinged to the top left side of the base 1. The piston rods of the two hydraulic cylinders 2 are hinged to the left outer wall of the diagonal brace 3. The diagonal brace 3 includes an outer frame as the main body, and several vertically parallel support rods 30 are fixedly installed inside the outer frame. A vertically movable crossbeam 4 is provided at the top of the diagonal brace 3. A first motor 40 is fixedly installed at both ends of the crossbeam 4. The output shaft of each first motor 40 is coaxially fixed with a first threaded rod 41, which is threadedly connected to the outer frame. By hinged to the diagonal brace 3 on the top right side of the base 1 and driven by the two symmetrically arranged hydraulic cylinders 2 on the left side, the angle of the diagonal brace 3 can be flexibly adjusted to adapt to large air-raid shelter doors with different placement requirements. Meanwhile, the crossbeam 4 moves up and down through the cooperation of the first motor 40 and the first threaded rod 41, which facilitates precise adjustment according to the height of the air defense door, improves the versatility and practicality of the placement frame, and makes it convenient to place large air defense doors stably and efficiently.

[0026] As a preferred technical solution, several insertion shafts 42 are fixedly installed at the bottom of the crossbeam 4, each aligned vertically with the support rod 30. The insertion shafts 42 pass through the outer frame and the support rod 30 and are inserted into the support rod 30. The insertion shafts 42 that cooperate with the support rod 30 can increase the stability of the crossbeam 4 during its vertical movement.

[0027] As a preferred technical solution, a horizontal plate 31 is fixedly connected to the outer left side of the inclined support plate 3 near the middle, and the piston rod of the hydraulic cylinder 2 is hinged to the horizontal plate 31 via a hinge seat. The horizontal plate 31 is used to hinge the inclined support plate 3 to the piston rod of the hydraulic cylinder 2.

[0028] As a preferred technical solution, an extension plate 10 is welded and fixed to the outer left side of the base 1, and the extension plate 10 has several fixing holes 11. The extension plate 10 and the fixing holes 11 facilitate the fixing of the base 1.

[0029] As a preferred technical solution, a movable plate 5 that can extend to the right is installed at the bottom of the base 1. A baffle 50 is fixedly installed on the outer right side of the movable plate 5, and the top of the baffle 50 is higher than the top of the movable plate 5. The movable plate 5 and the baffle 50 can limit the bottom of the air-raid shelter door to prevent the bottom of the air-raid shelter door from sliding outward, thereby increasing the stability of the air-raid shelter door when placed. The position of the baffle 50 can be adjusted to be used in conjunction with the tilt angle of the diagonal brace 3.

[0030] As a preferred technical solution, the bottom of the base 1 is provided with a mounting groove 12 for mounting the movable plate 5, and the movable plate 5 is slidably connected to the mounting groove 12. The mounting groove 12 is used to mount the movable plate 5 and provides stable guidance for the extension and retraction of the movable plate 5.

[0031] As a preferred technical solution, a second motor 51 is fixedly installed near both ends of the baffle 50. A second lead screw 52 is fixedly installed on the output shaft of each second motor 51, and the second lead screw 52 is threadedly connected to the base 1. With the second motor 51 driving the second lead screw 52 to rotate, and utilizing the threaded connection between the lead screw and the base 1, the movable plate 5 can automatically extend and retract without manual operation, improving operational convenience and efficiency.

[0032] As a preferred technical solution, the bottoms of both the movable plate 5 and the baffle 50 are flush with the bottom of the base 1, thus increasing the flatness of the bottom of the base 1.

[0033] When using the large air-raid shelter door placement frame of this utility model, firstly, according to the size and placement requirements of the large air-raid shelter door, activate the two hydraulic cylinders 2 symmetrically arranged on the top left side of the base 1. The piston rods of the hydraulic cylinders 2 extend and retract, applying force through the hinge point with the horizontal plate 31 on the left outer wall of the diagonal support plate 3, causing the diagonal support plate 3 to rotate around its hinge point with the top right side of the base 1, thereby flexibly adjusting the angle of the diagonal support plate 3 to achieve a suitable tilt state for the placement of the air-raid shelter door.

[0034] Next, based on the height of the air-raid shelter door, the first motors 40 at both ends of the crossbeam 4 are activated. The output shaft of the first motor 40 drives the coaxially fixed first threaded rod 41 to rotate. Since the first threaded rod 41 is threadedly connected to the outer frame of the diagonal brace plate 3, under the action of threaded transmission, the crossbeam 4 moves up and down along the outer frame, precisely adjusting to a position suitable for the height of the air-raid shelter door. At this time, the insertion shaft 42 at the bottom of the crossbeam 4, which is aligned vertically with the support rod 30, automatically inserts into the support rod 30, further fixing the crossbeam 4 and enhancing the stability of the crossbeam 4 when supporting the air-raid shelter door.

[0035] Then, if it is necessary to limit the bottom of the air-raid shelter door, the second motors 51 at both ends of the baffle 50 are activated. The output shaft of the second motor 51 drives the second lead screw 52 to rotate. By utilizing the threaded connection between the second lead screw 52 and the base 1, the rotational motion is converted into linear motion, driving the movable plate 5 to extend to the right along the mounting groove 12 at the bottom of the base 1. The baffle 50 on the outer right side of the movable plate 5 extends accordingly, and the top of the baffle 50 is higher than the top of the movable plate 5, which can effectively block the bottom of the air-raid shelter door and prevent it from sliding outward.

[0036] Finally, the large air-raid shelter door is placed on the diagonal bracing plate 3, the crossbeam 4 supports the upper part of the air-raid shelter door, and the movable plate 5 and the baffle 50 limit the bottom of the air-raid shelter door, forming a stable support structure. If the placement frame needs to be fixed in a certain place, it can be connected to the ground or other fixed structures through the fixing holes 11 on the extension plate 10 on the left outer wall of the base 1, ensuring that the entire placement process is safe, stable and efficient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
