Description

Technical Field

[0001] The utility model belongs to the technical field of civil air defense doors, and particularly relates to a hydraulic correction device for a civil air defense door frame. Background Technique

[0002] Most of the small assembled civil air defense door frames are formed by welding angle steel, steel plates or cold-rolled profiles, with a certain length and width. Due to errors in manual frame assembly and the high temperature generated by welding of steel, deformation is likely to occur. When the size exceeds the specification, correction is necessary.

[0003] For example, the Chinese patent with the publication number CN218775538U discloses a civil air defense door frame correction device, including a processing table. A placement groove is opened at the upper end of the processing table. Two symmetrically arranged abutting plates are slidably connected to the upper end of the processing table. A sliding rod is fixed to the side of the abutting plate, and a fixing mechanism is arranged at the upper end of the processing table. When correcting the door frame, the fixing mechanism is used to clamp and limit the door frame, facilitating correction and reducing the situation that the correction effect is affected due to the position deviation of the door frame during the correction process. When it is necessary to correct different positions of the door frame, the bearing platform is moved to move the position of the hydraulic cylinder to correct different positions of the door frame. According to the correction requirements, the height of the hydraulic cylinder is adjusted by the lifting component to expand the scope of use and improve the correction effect. However, the deformation of the door frame is not in a single direction. The same door frame may have concave deformation or convex deformation. Through the device provided by this device, the door frame needs to be adjusted back and forth and reversed during the correction process. In view of this, we propose a hydraulic correction device for a civil air defense door frame. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hydraulic correction device for a civil air defense door frame aiming at the above-mentioned existing technical problems, so as to achieve the effect of avoiding frequent adjustment of the door frame.

[0005] In view of this, the utility model provides a hydraulic correction device for a civil air defense door frame, including a support plate. Limiting beams are fixedly installed at the front and rear ends of the support plate. Positioning blocks are symmetrically installed on the upper surface of the support plate. Bearing grooves are symmetrically opened on the upper surface of the support plate. An installation plate is arranged inside the bearing groove. A hydraulic extrusion mechanism is slidably connected above the installation plate. The free ends of the two hydraulic extrusion mechanisms approach each other.

[0006] Preferably, a slider is arranged below the fixed end of the hydraulic extrusion mechanism. A chute is opened on the surface of the installation plate. The slider is slidably connected inside the chute. Two hydraulic extrusion mechanisms slide above each installation plate. The hydraulic extrusion mechanisms above the same installation plate are symmetrically arranged. A double-headed stud is engaged in the middle of the slider. The double-headed stud penetrates through the support plate and extends to the outside of the support plate. A motor is fixedly installed outside one of the support plates. The output end of the motor is fixedly connected to the double-headed stud.

[0007] Preferably, the cross-sectional shape of the mounting plate is "L", the mounting plate is fixedly installed inside the bearing groove, and the mounting plate and the support plate are fixedly connected by support blocks.

[0008] Preferably, the fixed end part of the hydraulic extrusion mechanism is located inside the bearing groove, and the free end of the hydraulic extrusion mechanism is located above the support plate.

[0009] Preferably, the two limiting beams are provided with slots, insertion blocks are inserted inside the slots, the two insertion blocks are fixedly connected by an extrusion plate, and the center line of the extrusion plate and the center lines between the two sliding grooves are located in the same vertical plane.

[0010] Preferably, an electromagnetic plate is fixedly installed above the free end of the hydraulic extrusion mechanism, a sliding rod is fixedly installed on the side of the electromagnetic plate away from the fixed end of the hydraulic extrusion mechanism, a sliding sleeve is slidably connected to the outer surface of the sliding rod, a magnetic ring is fixedly installed on the side of the sliding sleeve close to the electromagnetic plate, and a pressing switch for controlling the hydraulic extrusion mechanism is fixedly installed at the end of the sliding sleeve away from the electromagnetic plate.

[0011] The beneficial effects of the present utility model are:

[0012] 1. For this hydraulic correction device for civil air defense door frames, the door frame is placed above the support plate and its position can be restricted by positioning blocks and limiting beams. The deformed part of the door frame is arranged between two symmetrically arranged hydraulic extrusion mechanisms on the left and right. Among them, the two hydraulic extrusion mechanisms that do not participate in the correction remain extended to fix the door frame, and the participating one gradually extends the hydraulic extrusion mechanism on one side while the other side gradually contracts, so as to correct the door frame. When encountering a depression that needs to be corrected, just change the extrusion direction to achieve correction, thus avoiding the need to frequently adjust the position of the door frame during the correction process.

[0013] 2. For this hydraulic correction device for civil air defense door frames, an electromagnetic plate is fixedly installed above the free end of the hydraulic extrusion mechanism, a sliding rod is fixedly installed on the side of the electromagnetic plate away from the fixed end of the hydraulic extrusion mechanism, a sliding sleeve is slidably connected to the outer surface of the sliding rod, a magnetic ring is fixedly installed on the side of the sliding sleeve close to the electromagnetic plate, and a pressing switch for controlling the hydraulic extrusion mechanism is fixedly installed at the end of the sliding sleeve away from the electromagnetic plate. In this embodiment, the electromagnetic plate corresponding to the hydraulic extrusion mechanism participating in the extrusion always remains energized, driving the magnetic ring to squeeze the sliding sleeve to the outermost side. When the pressing switch contacts the extrusion plate, the hydraulic extrusion mechanism just corrects the door frame, and the hydraulic extrusion mechanism is turned off through the pressing switch to avoid overcorrection.

Specific implementation manner

[0021] The following further elaborates on this application in conjunction with the attached Figures 1 - 5 to provide a more detailed description of this application.

[0022] In this application, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe this application and its embodiments, and are not used to limit that the indicated device, element, or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0023] An embodiment of this application discloses a hydraulic correction device for a civil air defense door frame, including a support plate 1. Limit beams 2 are fixedly installed at the front and rear ends of the support plate 1. Positioning blocks 3 are symmetrically installed on the upper surface of the support plate 1. Bearing grooves 4 are symmetrically opened on the upper surface of the support plate 1. A mounting plate 5 is arranged inside the bearing groove 4. A hydraulic extrusion mechanism 6 is slidably connected above the mounting plate 5. The free ends of the two hydraulic extrusion mechanisms 6 approach each other.

[0024] Based on the above structure,

[0025] In one embodiment, a slider 18 is provided below the fixed end of the hydraulic extrusion mechanism 6. A chute 19 is formed on the surface of the mounting plate 5. The slider 18 is slidably connected to the inside of the chute 19. Two hydraulic extrusion mechanisms 6 slide above each mounting plate 5. The hydraulic extrusion mechanisms 6 above the same mounting plate 5 are symmetrically arranged. A double-headed stud 7 is engaged in the middle of the slider 18. The double-headed stud 7 penetrates through the support plate 1 and extends to the outside of the support plate 1. A motor 8 is fixedly installed outside one of the support plates 1. The output end of the motor 8 is fixedly connected to the double-headed stud 7. Specifically, the thread directions of the double-headed stud 7 are opposite and the lengths are the same, which can control the two hydraulic extrusion mechanisms 6 on the same mounting plate 5 to move towards each other.

[0026] In this embodiment, by providing two hydraulic extrusion mechanisms 6 that can move towards each other, the door frame can be supported to prevent the position of the door frame from changing during the extrusion process.

[0027] Based on the above structure,

[0028] In one embodiment, the cross-sectional shape of the mounting plate 5 is "L"-shaped. The mounting plate 5 is fixedly installed inside the bearing groove 4. The mounting plate 5 is fixedly connected to the support plate 1 through a support block 9. Specifically, the function of the mounting plate 5 is to install the hydraulic extrusion mechanism 6 and can limit the hydraulic extrusion mechanism 6 to slide.

[0029] In this embodiment, through such a setting, the position of the mounting plate 5 can be limited to prevent the mounting plate 5 from moving during the extrusion process.

[0030] Based on the above structure,

[0031] In one embodiment, a part of the fixed end of the hydraulic extrusion mechanism 6 is located inside the bearing groove 4, and the free end of the hydraulic extrusion mechanism 6 is located above the support plate 1. Specifically, the free end of the hydraulic extrusion mechanism 6 has the same width as the door frame.

[0032] In this embodiment, through such a setting, the free end of the hydraulic extrusion mechanism 6 can be in full contact with the door frame so as to adjust the deformed position.

[0033] Based on the above structure,

[0034] In one embodiment, two limiting beams 2 are provided with slots 10. Plug blocks 11 are inserted into the slots 10. The two plug blocks 11 are fixedly connected through an extrusion plate 12. The center line of the extrusion plate 12 and the center line between the two chutes 19 are located in the same vertical plane. Specifically, the cross-sectional shape of the extrusion plate 12 is "T"-shaped. In this embodiment, the extrusion plate 12 can play a role in visually observing the center of the door, and it can be determined whether the extruded door frame is vertical by observation.

[0035] Based on the above structure,

[0036] In one embodiment, an electromagnetic plate 13 is fixedly installed above the free end of the hydraulic extrusion mechanism 6. On the side of the fixed end of the electromagnetic plate 13 away from the hydraulic extrusion mechanism 6, a sliding rod 14 is fixedly installed. A sliding sleeve 15 is slidably connected to the outer surface of the sliding rod 14. A magnetic ring 16 is fixedly installed on the side of the sliding sleeve 15 close to the electromagnetic plate 13. A push switch 17 for controlling the hydraulic extrusion mechanism 6 is fixedly installed at one end of the sliding sleeve 15 away from the electromagnetic plate 13. In this embodiment, the electromagnetic plate 13 corresponding to the hydraulic extrusion mechanism 6 participating in the extrusion always remains energized, driving the magnetic ring 16 to drive the sliding sleeve 15 to be extruded to the outermost side. When the push switch 17 contacts the extrusion plate 12, the hydraulic extrusion mechanism 6 just corrects the door frame and closes the hydraulic extrusion mechanism 6 through the push switch 17 to avoid overcorrection. The push switch 17 corresponding to the hydraulic extrusion mechanism 6 that does not participate in the extrusion contracts to the inside of the free end, and the repulsive force between the magnetic ring 16 and the electromagnetic plate 13 is much greater than the response pressure of the push switch.

[0037] When the hydraulic correction device for a civil air defense door frame of this embodiment is in use, the door frame is placed above the support plate 1, and the position of the door frame can be restricted by the positioning blocks 3 and the limiting beams 2. The deformed part of the door frame is arranged between two symmetrically arranged hydraulic extrusion mechanisms 6 on the left and right. Among them, the two hydraulic extrusion mechanisms 6 that do not participate in the correction remain extended to fix the door frame, and the participating hydraulic extrusion mechanism 6 gradually extends through the protruding side while the other hydraulic extrusion mechanism 6 gradually contracts, so as to correct the door frame. When encountering a depression that needs to be corrected, the extrusion direction can be changed to achieve correction, thus avoiding the need to frequently adjust the position of the door frame during the correction process. After the position correction is completed, by rotating the double-headed stud 7, the hydraulic extrusion mechanisms 6 move towards each other, and then the position of the hydraulic extrusion mechanisms 6 can be adjusted to perform correction again, so as to ensure that the door frame does not move during the extrusion process.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
