Description

Technical Field

[0001] This utility model relates to the field of protective door installation technology, and in particular to an auxiliary device for the installation of protective doors in civil defense projects. Background Technology

[0002] In the construction of civil defense projects, the installation of protective doors is of paramount importance, but the traditional installation process for protective doors in civil defense projects presents many challenges.

[0003] On the one hand, protective doors are usually large and heavy, making it difficult to accurately adjust their height and angle during installation. Existing installation equipment cannot flexibly meet the diverse needs for the height and tilt angle of protective doors in different installation scenarios, resulting in low installation efficiency and a high risk of installation errors. On the other hand, the lack of effective fixing and auxiliary movement measures during the fixing and transportation of protective doors makes them unstable during installation and operation, and results in greater friction during placement and movement. This not only increases the difficulty of construction but may also damage the protective doors, affecting their protective performance and service life.

[0004] Therefore, we propose an auxiliary device for the installation of protective doors in civil defense projects. Utility Model Content

[0005] The main purpose of this utility model is to provide an installation auxiliary device for protective doors in civil defense projects. In order to prevent problems such as low installation efficiency, large installation errors, poor stability of protective door installation, increased construction difficulty, and damage to the protective door due to friction, which affects the protective performance and service life, this device can improve the installation quality and efficiency of protective doors in civil defense projects, reduce construction costs and safety risks, and extend the service life of the protective doors. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An installation auxiliary device for a civil defense engineering protective door includes an installation auxiliary frame. Two drive adjustment components are symmetrically arranged at the top of the installation auxiliary frame. A support frame is provided at the top of the two drive adjustment components. Each drive adjustment component includes a movable component and a drive component. The movable component includes a first rotating frame, a second rotating frame, a connecting seat, and a slider. One end of the first rotating frame is hinged to one end of the installation auxiliary frame. The middle part of the second rotating frame is hinged to the other end of the first rotating frame. The connecting seat is hinged to one end of the second rotating frame and connected to the bottom of the support frame. Both sides of the slider are respectively hinged to the other end of the second rotating frame. The drive component is disposed on the slider.

[0008] The drive assembly includes a sliding seat, a first lead screw, and a first drive motor. The sliding seat is mounted on an auxiliary mounting bracket. The slider is slidably connected to the sliding seat. The first lead screw passes through the sliding seat and is threadedly connected to the slider. The first drive motor is located on the side of the sliding seat away from the slider, and the output end of the first drive motor is connected to one end of the first lead screw.

[0009] The support frame has two side plates vertically fixedly connected to its outer walls on both sides, and the two side plates are symmetrically arranged. A second drive motor is fixedly installed on the top of the side plate. A second lead screw is rotatably connected to one side of the side plate. The output end of the first drive motor is connected to the top end of the first lead screw. A horizontal plate is threaded to the outside of the second lead screw. Multiple first hydraulic rods are fixedly installed on the horizontal plate at equal intervals. The output end of the first hydraulic rod passes through the horizontal plate and is fixedly connected to a retainer. Multiple retaining seats are provided on the inner wall of the bottom of the support frame. Multiple rollers are horizontally arranged at equal intervals on the bottom inner side of the retaining seats.

[0010] By adopting the above technical solution, when the height of the support frame needs to be adjusted, the first drive motor is started, which drives the first lead screw to rotate. Since the first lead screw is threadedly connected to the slider and the slider is slidably connected to the sliding seat, the slider will slide along the axial direction of the first lead screw on the sliding seat. The sliding of the slider will drive the second rotating frame, which is hinged to it, to move. Because the middle of the second rotating frame is hinged to the first rotating frame, one end of the first rotating frame is hinged to the installation auxiliary frame, and one end of the second rotating frame is hinged to the connecting seat, and the connecting seat is connected to the bottom of the support frame, the support frame can be raised or lowered through the linkage of the first and second rotating frames. If the support frame is to be tilted, only the second rotating frame in one of the drive adjustment components can be controlled to drive the support frame connected to it to rise or fall, while the other drive adjustment component remains stationary, thereby realizing the adjustment of the tilt angle of the support frame to adapt to different installation requirements.

[0011] After the second drive motor on the side plate on both sides of the support frame is started, it will drive the second lead screw to rotate. Because the second lead screw is threadedly connected to the horizontal plate, the horizontal plate will move along the axial direction of the second lead screw inside the side plate, thereby realizing the adjustment of the up and down position of the horizontal plate. In this way, the horizontal plate can drive multiple first hydraulic rods to move synchronously, thereby fixing multiple protective door bodies synchronously.

[0012] Multiple hydraulic rods are installed on the horizontal plate, and multiple mounting brackets can hold multiple protective door bodies. When the protective door body is placed on the mounting bracket on the support frame, the first hydraulic rod is activated, and its output end extends, causing the mounting sleeve to move downward. The mounting sleeve can clamp and fix the protective door body on the mounting bracket of the support frame for easy transportation. Conversely, when the protective door body is being installed, the output end of the first hydraulic rod retracts, causing the mounting sleeve to move upward, and the mounting sleeve releases the fixation on the protective door body. At the same time, multiple rollers arranged on the bottom of the mounting brackets on the inner side of the bottom wall of the support frame can provide support and reduce friction when the protective door is placed and moved, making the movement of the protective door smoother.

[0013] Furthermore, a protective door body is installed between the corresponding card sleeve and the card seat, and the protective door body is located directly above the roller.

[0014] By adopting the above technical solution, when the protective door body is transported, it is first placed directly above the rollers. Since the rollers are arranged horizontally at equal intervals on the bottom of the inner side of the card seat, they can provide stable support and greatly reduce the friction when the protective door body moves. This allows the protective door body to be adjusted in position on the support frame more easily, which is convenient for initial positioning.

[0015] Subsequently, the first hydraulic rod on the horizontal plate is activated, and its output end drives the clamp to move downward. As the clamp gradually approaches the protective door body and finally clamps it, the protective door body is firmly fixed in the vertical direction. The clamp and the clamp work together to keep the protective door body stable throughout the transportation process and avoid shaking and displacement.

[0016] Furthermore, two reinforcing ribs are provided between each pair of side plates and the support frame.

[0017] By adopting the above technical solution, these reinforcing ribs can enhance the connection strength between the side plate and the support frame, effectively disperse the stress generated during the installation of the protective door body. When the protective door body is placed on the support frame and a series of adjustments and fixing operations are performed, the reinforcing ribs can prevent the side plate and the support frame from deforming due to large pressure or external force, further ensuring the stability of the entire installation auxiliary device and ensuring the smooth installation of the protective door.

[0018] Furthermore, two second hydraulic rods are fixedly installed on the outer walls of both sides of the installation auxiliary frame, and a support plate is fixedly connected to the bottom end of each pair of second hydraulic rods.

[0019] By adopting the above technical solution, after the installation auxiliary device is in place, the second hydraulic rod is activated according to the actual working scenario and ground conditions. The extension and retraction of the second hydraulic rod can adjust its own length. As the second hydraulic rod extends or shortens, the support plate fixedly connected to the bottom end of the second hydraulic rod also moves up and down. When it is necessary to enhance the stability of the installation auxiliary frame, the second hydraulic rod is extended so that the support plate contacts the ground and provides support force. By increasing the contact area with the ground, the pressure brought by the installation auxiliary frame and the protective door body is effectively distributed, preventing the installation auxiliary frame from shaking or tilting during operation, and ensuring the stability and safety of the entire installation process. If it is necessary to move the installation auxiliary device, the second hydraulic rod is shortened so that the support plate is lifted off the ground, making it easier to adjust the position of the installation auxiliary frame.

[0020] Furthermore, a push handle is fixedly connected to one end of the installation auxiliary frame, and the push handle is provided with a rubber handrail.

[0021] By adopting the above technical solution, workers can hold the rubber handle on the push handle and use the good anti-slip and grip comfort of the rubber handle to push the installation auxiliary frame more easily and stably, making it easier to adjust its position and move the installation auxiliary device to a suitable work location, thereby improving the convenience and efficiency of the installation work.

[0022] Furthermore, casters are provided at the four corners of the bottom of the mounting auxiliary frame.

[0023] By adopting the above technical solution, when it is necessary to move the installation auxiliary device, the second hydraulic rod is first shortened to lift the support plate off the ground. At this time, the casters bear the weight of the installation auxiliary frame and related components. The casters have the characteristic of free steering. The workers can hold the push handle at one end of the installation auxiliary frame and easily push the installation auxiliary frame to achieve flexible steering and position adjustment. The installation auxiliary device can be conveniently moved to different installation positions in the civil defense project, which greatly improves the efficiency and convenience of the installation work. During the movement, the rolling of the casters can effectively reduce friction and reduce the physical exertion of the workers, making the whole installation process smoother.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) This utility model provides an installation auxiliary device for a civil defense engineering protective door. Through a uniquely designed drive adjustment component, including a movable component and a drive component, the height of the support frame can be adjusted conveniently and quickly. The first drive motor is started, and the second rotating frame is moved by the threaded connection between the first lead screw and the slider and the sliding cooperation between the slider and the sliding seat. Then, the support frame is raised and lowered by the linkage between the first rotating frame and the second rotating frame. Moreover, only one drive adjustment component needs to be controlled to work while the other remains stationary, so as to easily adjust the tilt angle of the support frame. This greatly improves the adaptability of the device to different installation requirements and effectively improves the installation efficiency and accuracy.

[0026] (2) The present invention provides an auxiliary device for the installation of a civil defense engineering protective door. The second drive motor on both sides of the support frame can adjust the position of the horizontal plate, thereby driving multiple first hydraulic rods to move synchronously. When the protective door is placed on the card seat, the first hydraulic rods are activated, and the card sleeve can clamp and fix the protective door, ensuring the stability of the installation process. At the same time, multiple rollers arranged at the bottom of the inner side of the card seat play a supporting role and reduce friction when the protective door is placed and moved, making the protective door move more smoothly, reducing the construction difficulty, and reducing the risk of damage to the protective door during the installation process.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To prevent problems such as low installation efficiency, large installation errors, poor stability during installation of protective doors, increased construction difficulty, and damage to protective doors due to friction that affects their protective performance and service life, and to improve the installation quality and efficiency of protective doors in civil defense projects, reduce construction costs and safety risks, and extend the service life of protective doors, such as... Figure 1 , Figure 2 , Figure 3 As shown, an installation auxiliary device for a civil defense engineering protective door includes an installation auxiliary frame 1. Two drive adjustment components 2 are symmetrically arranged at the top of the installation auxiliary frame 1. A support frame 3 is provided at the top of the two drive adjustment components 2. Each drive adjustment component 2 includes a movable component 4 and a drive component 5. The movable component 4 includes a first rotating frame 6, a second rotating frame 7, a connecting seat 8, and a slider 9. One end of the first rotating frame 6 is hinged to one end of the installation auxiliary frame 1. The middle part of the second rotating frame 7 is hinged to the other end of the first rotating frame 6. The connecting seat 8 is hinged to one end of the second rotating frame 7 and connected to the bottom of the support frame 3. Both sides of the slider 9 are respectively hinged to the other end of the second rotating frame 7. The drive component 5 is disposed on the slider 9.

[0033] The drive assembly 5 includes a sliding seat 10, a first lead screw 11, and a first drive motor 12. The sliding seat 10 is mounted on the mounting auxiliary frame 1. The slider 9 is slidably connected to the sliding seat 10. The first lead screw 11 passes through the sliding seat 10 and is threadedly connected to the slider 9. The first drive motor 12 is located on the side of the sliding seat 10 away from the slider 9, and the output end of the first drive motor 12 is connected to one end of the first lead screw 11.

[0034] The support frame 3 has two side plates 13 vertically fixedly connected to its outer walls on both sides, and the two side plates 13 are symmetrically arranged. A second drive motor 15 is fixedly installed on the top of the side plate 13. A second lead screw 14 is rotatably connected to one side of the inside of the side plate 13. The output end of the first drive motor 12 is connected to the top end of the first lead screw 11. A horizontal plate 16 is threadedly connected to the outside of the second lead screw 14. Multiple first hydraulic rods 17 are fixedly installed on the horizontal plate 16 at equal intervals. The output end of the first hydraulic rod 17 passes through the horizontal plate 16 and is fixedly connected to a retainer 18. Multiple retaining seats 19 are provided on the inner wall of the bottom of the support frame 3. Multiple rollers 20 are horizontally arranged at equal intervals on the inner bottom of the retaining seats 19.

[0035] When adjusting the height of the support frame 3, the first drive motor 12 is activated, which drives the first lead screw 11 to rotate. Since the first lead screw 11 is threadedly connected to the slider 9 and the slider 9 is slidably connected to the sliding seat 10, the slider 9 will slide along the axial direction of the first lead screw 11 on the sliding seat 10. The sliding of the slider 9 will drive the second rotating frame 7, which is hinged to it, to move. The middle of the second rotating frame 7 is hinged to the first rotating frame 6, one end of the first rotating frame 6 is hinged to the mounting auxiliary frame 1, and one end of the second rotating frame 7 is hinged to the connecting seat 8, which is connected to the bottom of the support frame 3. Thus, the support frame 3 can be raised or lowered through the linkage of the first rotating frame 6 and the second rotating frame 7. If the support frame 3 is to be tilted, only the second rotating frame 7 in one of the drive adjustment components 2 can be controlled to drive the support frame 3 connected to it to rise or fall, while the other drive adjustment component 2 remains stationary. This allows for the adjustment of the tilt angle of the support frame 3 to adapt to different installation requirements.

[0036] After the second drive motor 15 on the side plates 13 on both sides of the support frame 3 is started, it will drive the second lead screw 14 to rotate. Because the second lead screw 14 is threadedly connected to the horizontal plate 16, the horizontal plate 16 will move along the axial direction of the second lead screw 14 inside the side plate 13, thereby realizing the adjustment of the vertical position of the horizontal plate 16. In this way, the horizontal plate 16 can synchronously drive multiple first hydraulic rods 17 to move synchronously, thereby synchronously fixing multiple protective door bodies 21.

[0037] Multiple first hydraulic rods 17 are installed on the horizontal plate 16, and multiple brackets 19 can hold multiple protective door bodies 21. When the protective door body 21 is placed on the bracket 19 on the support frame 3, the first hydraulic rod 17 is activated, the output end of the first hydraulic rod 17 extends, and drives the sleeve 18 to move downward. The sleeve 18 can clamp and fix the protective door body 21 on the bracket 19 of the support frame 3 for easy transportation. Conversely, when the protective door body 21 is installed, the output end of the first hydraulic rod 17 retracts, and drives the sleeve 18 to move upward. The sleeve 18 releases the fixation of the protective door body 21. At the same time, multiple rollers 20 arranged on the bottom of the inner side of the bracket 19 on the inner wall of the bottom end of the support frame 3 can provide support and reduce friction when the protective door is placed and moved, making the movement of the protective door smoother.

[0038] For example, such as Figure 3 As shown, the present invention also includes a protective door body 21 installed between the card sleeve 18 and the card seat 19, and the protective door body 21 is located directly above the roller 20.

[0039] When the protective door body 21 is being transported, it is first placed directly above the rollers 20. Since the rollers 20 are arranged horizontally at equal intervals on the bottom of the inner side of the card seat 19, they can provide stable support and greatly reduce the friction when the protective door body 21 moves, so that the protective door body 21 can be adjusted in position on the support frame 3 more easily, which is convenient for initial positioning.

[0040] Subsequently, the first hydraulic rod 17 on the horizontal plate 16 is activated, and its output end drives the clamp 18 to move downward. As the clamp 18 gradually approaches the protective door body 21 and finally clamps it, the protective door body 21 is firmly fixed in the vertical direction. The clamp 18 and the clamp seat 19 work together to keep the protective door body 21 stable throughout the transportation process and avoid shaking and displacement.

[0041] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes two reinforcing ribs 22 provided between each pair of side plates 13 and support frame 3.

[0042] When in use, these reinforcing ribs 22 can enhance the connection strength between the side plate 13 and the support frame 3, effectively disperse the stress generated during the installation of the protective door body 21. When the protective door body 21 is placed on the support frame 3 and a series of adjustments and fixing operations are performed, the reinforcing ribs 22 can prevent the side plate 13 and the support frame 3 from deforming due to bearing large pressure or external force, further ensuring the stability of the entire installation auxiliary device and ensuring the smooth installation of the protective door.

[0043] For example, such as Figure 1 As shown, the present invention also includes two second hydraulic rods 23 fixedly installed on the outer walls of both sides of the installation auxiliary frame 1, and a support plate 24 is fixedly connected to the bottom end of each pair of second hydraulic rods 23.

[0044] In use, after the installation auxiliary device is in place, the second hydraulic rod 23 is activated according to the actual working scene and ground conditions. The extension and retraction of the second hydraulic rod 23 can adjust its own length. As the second hydraulic rod 23 extends or shortens, the support plate 24, which is fixedly connected to the bottom end of the second hydraulic rod 23, also moves up and down. When it is necessary to enhance the stability of the installation auxiliary frame 1, the second hydraulic rod 23 is extended so that the support plate 24 contacts the ground and provides support force. By increasing the contact area with the ground, the pressure brought by the installation auxiliary frame 1 and the protective door body 21 is effectively distributed, preventing the installation auxiliary frame 1 from shaking or tilting during operation, and ensuring the stability and safety of the entire installation process. If it is necessary to move the installation auxiliary device, the second hydraulic rod 23 is shortened so that the support plate 24 is lifted off the ground, making it easier to adjust the position of the installation auxiliary frame 1.

[0045] For example, such as Figure 1As shown, the present invention also includes a push handle 25 fixedly connected to one end of the mounting auxiliary frame 1, and the push handle 25 is provided with a rubber handrail.

[0046] When in use, the staff can hold the rubber handle on the push handle 25 and use the good anti-slip and grip comfort of the rubber handle to push the installation auxiliary frame 1 more easily and stably, so as to adjust its position and move the installation auxiliary device to a suitable work location, thereby improving the convenience and efficiency of the installation work.

[0047] For example, such as Figure 1 As shown, the present invention also includes casters 26 at the four corners of the bottom of the mounting auxiliary frame 1.

[0048] When the installation auxiliary device needs to be moved during use, the second hydraulic rod 23 is first shortened to lift the support plate 24 off the ground. At this time, the caster wheel 26 bears the weight of the installation auxiliary frame 1 and related components. The caster wheel 26 has the characteristic of 360-degree free rotation. The staff can hold the push handle 25 at one end of the installation auxiliary frame 1 and easily push the installation auxiliary frame 1 to achieve flexible turning and position adjustment. The installation auxiliary device can be conveniently moved to different installation positions in the civil defense project, which greatly improves the efficiency and convenience of the installation work. During the movement, the rolling of the caster wheel 26 can effectively reduce friction and reduce the physical exertion of the staff, making the whole installation process smoother.

[0049] It should be noted that this utility model is an installation auxiliary device for a civil defense engineering protective door. The protective door body 21 is placed directly above the roller 20. The roller reduces friction, which facilitates position adjustment and initial positioning. The second drive motor 15 is started, which drives the second lead screw 14 to rotate, causing the horizontal plate 16 to move, which in turn drives the first hydraulic rod 17. The first hydraulic rod 17 is started, and its output end drives the clamp 18 to clamp the protective door downward.

[0050] When the device needs to be moved, the second hydraulic rod 23 is shortened, and flexible steering and position adjustment are achieved through the push handle 25 and the caster wheel 26;

[0051] The second hydraulic rod 23 is activated according to the ground conditions. When it extends, the support plate 24 contacts the ground to enhance stability, and when it shortens, it is easy to move.

[0052] Start the first drive motor 12 to drive the first lead screw 11 to rotate, so that the slider 9 slides on the sliding seat 10. Through the linkage of the first rotating frame 6 and the second rotating frame 7, the support frame 3 can be raised or lowered. Control one of the drive adjustment components 2 to work and the other to stay still, so that the support frame 3 can be tilted to adapt to different installation requirements.

[0053] During installation, reinforcing rib 22 ensures the stability of the device.

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 illustrative of the principles of this utility model.
