Description

Technical Field

[0001] The present invention relates to the technical field of civil air defense door pipes, and in particular to an automatic unloading device for pipes used in the production of civil air defense doors. Background Art

[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. They are clearly classified, including ordinary single-leaf and double-leaf protective closed doors and closed doors, movable threshold single-leaf and double-leaf protective closed doors and closed doors, and other civil defense equipment. The commonly used pipes in civil defense doors are sleeves, that is, sleeves welded from straight pipes and water-stop wing rings. In civil buildings, civil defense closed sleeves are widely used in water supply and drainage pipes, HVAC pipes, electrical lines and other fields to ensure the normal operation of buildings and the safety of personnel. In industrial plants, petrochemicals, electric power and other industries, civil defense closed sleeves can effectively protect pipelines and equipment, prevent damage and leakage caused by external impact or vibration, and ensure production safety.

[0003] The existing casings used in the production of civil air defense doors are generally prepared by welding straight pipes and water stop wing rings on a workbench, and then manually transported to a storage location after welding. The casings are usually placed vertically, that is, the central axis of the straight pipe is vertical to the ground. Since they need to be manually transported after welding, they also need to be placed vertically, which requires a lot of labor, can easily cause muscle strain on workers, and wastes manpower.

[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art. Summary of the invention

[0005] The purpose of the present invention is to design a device which can quickly move the sleeve vertically to a desired stacking location after welding without manual handling, so as to solve the above-mentioned shortcomings in the technology.

[0006] The cam is secured to the bottom of the frame and is designed to be easily disengaged from the loadsheet, and the cam is secured to the bottom of the frame by a plurality of levers, each of which is secured to a plurality of trackpads, each of which is secured to a plurality of trackpads, each of which is secured to a plurality of trackpads.

[0007] After the water stop wing ring is welded to the outer circumference of the straight pipe on the welding table to form a casing, the vertical welding table is rotated to be parallel to the ground, and the casing rolls down on the ramp plate to accelerate. After passing through the guide limits of the upper and lower plates, the upper and lower bars, the casing is gradually changed from a horizontal state to a vertical state, and finally falls vertically from the vertical guide plate to the top of the existing liftable mobile trolley for stacking.

[0008] Preferably, the welding table includes a chassis rotatably connected to the mounting frame, and a semicircular plate fixedly installed on the top of the chassis, with an opening of the semicircular plate facing the ramp plate. When the central axis of the semicircular plate is parallel to the ground, the same plane on both sides of the semicircular plate is perpendicular to the ground, and the chassis is rotatably connected to the mounting frame.

[0009] Preferably, the support bar is fixedly installed on the inner circumferential surface of the semicircular plate. When the number of water stop wing rings on the existing sleeve is N, the number of the upper and lower strips and support bars is set to N-1, and the bottom surface of the water stop wing ring is in contact with the top surface of the support bar.

[0010] Preferably, the mounting frame includes a main frame, a suspension rod fixedly mounted on the top surface of the upper shift plate, an L-shaped mounting platform rotatably connected to the chassis, and support legs fixedly mounted on the L-shaped mounting platform and the bottom surface of the lower shift plate.

[0011] Preferably, when the center axis of the semicircular plate is parallel to the ground, the bottom surface of the support bar is higher than the top surface of the lower shifting bar on the ramp plate.

[0012] Preferably, a hydraulic cylinder is rotatably mounted on the L-shaped mounting platform, a connecting shaft is rotatably mounted on the end of the hydraulic cylinder output shaft, the end of the connecting shaft is fixedly connected to the outer wall of the welding platform, an arc groove is opened in the L-shaped mounting platform, and the connecting shaft is slidably connected in the arc groove.

[0013] Preferably, the spacing between the upper shifting plate and the lower shifting plate matches the diameter of the water stop wing ring on the existing casing, and the spacing between the upper shifting bar and the lower shifting bar matches the diameter of the straight pipe on the existing casing.

[0014] Preferably, the vertical guide plate includes a U-shaped collision plate fixedly connected to the ends of the upper and lower plates, and a straight slotted plate fixedly connected to the bottom of the U-shaped collision plate. The spacing between the two ends of the straight slotted plate is 1.5 times the diameter of the water-stop wing ring, and the straight slotted plate does not overlap with the end of the lower plate in the vertical direction.

[0015] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0016] 1. After welding is completed, the hydraulic cylinder can be directly started, and the sleeve can be transported over a long distance by using the cooperation between the upper and lower levers, the upper and lower levers, the upper and lower levers and the ramp plates. At the end of the transportation, the sleeve is dropped vertically to the desired stacking location, which solves the problem of heavy labor, easy muscle strain and manpower consumption in the existing manual handling technology;

[0017] 2. The welding table in this device is part of the material unloading structure. It not only assists the sleeve to roll into the upper surface of the ramp plate for unloading, but also can directly position the water stop wing ring and the straight pipe during welding. There is no need to manually control the distance between the water stop wing ring and the outer peripheral surface of the straight pipe, which assists workers in welding and speeds up production without the need to use a workbench for welding.

When the central axis of the semicircular plate 202 is parallel to the ground, the same plane on both sides of the semicircular plate 202 is perpendicular to the ground, the chassis 201 is rotatably connected to the mounting frame 1, the lower dial plate 4 is fixedly installed with the ramp plate 6 near one end of the welding table 2, the top of the ramp plate 6 is fixedly connected to the mounting frame 1, the upper dial plate 3 and the lower dial plate 4 A vertical guide plate 5 consisting of a U-shaped collision plate 501 and a straight notch plate 502 is installed together at one end away from the welding table 2, the upper and lower plates 3 and 4 are arranged in parallel, the upper and lower plates 3 and 4 are parallel to the ground at one end close to the welding table 2, and the upper and lower plates 3 and 4 are perpendicular to the ground at one end away from the welding table 2. The middle part of the upper and lower plates 3 and 4 is transitionally twisted, an upper strip 7 is fixedly installed on the bottom surface of the upper strip 3, and a lower strip 8 is fixedly installed on the top surface of the lower strip 4 and the ramp plate 6. The lower strip 8 on the lower strip 4 is parallel to the upper strip 7, and the torsion amplitude is the same as that of the lower strip 4. The semicircular plate 202 When the central axis is parallel to the ground, the bottom surface of the support bar 12 is higher than the top surface of the lower strip 8 on the ramp plate 6; the support bar 12 is fixedly installed in the inner circumference of the semicircular plate 202, and when the water stop wing ring on the existing casing is set to N, the number of the upper strip 7, the lower strip 8 and the support bar 12 is set to N-1; a hydraulic cylinder 9 is rotatably installed on the L-shaped mounting platform 103, and a connecting shaft 10 is rotatably installed at the end of the output shaft of the hydraulic cylinder 9, and the end of the connecting shaft 10 is fixedly connected to the outer wall of the welding platform 2, and an arc groove 11 is opened in the L-shaped mounting platform 103, and the connecting shaft 10 is slidably connected in the arc groove 11;

[0027] The user first places the water-stop wing rings to be welded on the same sleeve on each support bar 12 in turn, one of which is placed on the top surface of the disc, and the outer circumference of the water-stop wing ring is fitted with the inner circumference of the semicircular plate 202, then inserts the straight pipe on the sleeve into the water-stop wing ring, and welds the water-stop wing ring and the straight pipe, and starts the hydraulic cylinder 9 after welding is completed;

[0028] When the hydraulic cylinder 9 is started, the output shaft extends and moves from one end of the arc groove 11 to the other end, and drives the welding table 2 to rotate through the connecting shaft 10 in the arc groove 11. When the welding table 2 rotates from a vertical state to a horizontal state, the hydraulic cylinder 9 stops working, and the sleeve is gently pushed to slide toward the inclined plate;

[0029] When the sleeve slides on the inclined plate, the gravitational potential energy is converted into kinetic energy, so that it rolls between the upper plate 3 and the lower plate 4. With the limit between the upper plate 3, the lower plate 4, the upper bar 7 and the lower bar 8, the sleeve gradually changes from a parallel state to a vertical state during rolling. When the sleeve separates from the upper bar 7 and the lower bar 8, it hits the end of the U-shaped collision plate under the action of inertia, and then falls through the straight notch plate 502.

[0030] A movable and height-retractable electric cart commonly used in the prior art is arranged at the straight slot 502, and a storage rack is installed on the cart, and the sleeves in a vertical state will fall onto the storage rack for stacking;

[0031] The bottom height of the straight slot 502 can also be slightly larger than the vertical height of the sleeve, so that the welded sleeve can be quickly moved vertically to the vicinity of the desired stacking location and manually stacked, saving the time of manually moving the sleeve from the welding location to the stacking location.
