Description

Technical Field

[0001] This invention belongs to the field of civil defense door processing technology, and in particular relates to a concrete civil defense door pouring device and method. Background Technology

[0002] Civil defense doors refer to the doors at the entrances and exits of civil defense projects. They are generally used to provide protection in case of danger. Civil defense doors also include more than ten types such as hose-type blast wave breaker doors, pendulum-type blast wave (shielding) breaker doors, double-leaf protective airtight doors with two-way force at the connecting opening, fireproof airtight doors, fireproof airtight doors, and double-leaf protective airtight doors with ramps that open inward.

[0003] Concrete air-raid shelter doors are protective doors with a steel structure as the outer frame and reinforced concrete as the internal material. During the production process, steel bars need to be welded or tied inside the door frame before concrete is poured into it. However, during the pouring process, the delivery position of the concrete feeding equipment is relatively fixed, requiring the user to spread the concrete inside the door body to fill all positions inside the door frame. Therefore, a concrete air-raid shelter door pouring device and method are needed. This device uses a pouring equipment with adjustable pouring angle and pouring distance to control the concrete, ensuring that the concrete is accurately delivered to the designated position. It is also equipped with a traction structure to facilitate the user's movement of the unpoured and poured door frames. Summary of the Invention

[0004] The purpose of this invention is to provide a concrete blast door pouring device and method, which uses a pouring equipment with adjustable pouring angle and pouring distance to control the concrete, so that the concrete can be accurately delivered to the designated position. It is also equipped with a traction structure to facilitate the user to move the unpoured and poured door frame, thereby solving the above-mentioned technical problems.

The support frame is equipped with a feeding assembly, and a propulsion assembly is provided on the top of the support frame. The propulsion assembly includes propulsion cylinders fixedly installed on the front and rear sides of the top of the support frame. A slidable displacement slide plate is provided on the left side of the top of the support frame, and the displacement slide plate is connected to the output end of the propulsion cylinder. A connecting rod is fixedly connected to the left side of the bottom of the telescopic tube. An arc-shaped groove adapted to the connecting rod is opened on the top of the displacement slide plate, and the connecting rod is slidably connected to the inner cavity of the arc-shaped groove. Limiting guide rails are welded to the front and rear ends of the left side of the top of the support frame, and the displacement slide plate is slidably connected to the surface of the limiting guide rails. A rectangular through hole is opened on the left side of the top of the support frame, and the blast door frame is located directly below the inner cavity of the rectangular through hole.

[0006] Preferably, the inner cavity of the transfer tank is provided with a rotatable spiral conveying rod, a support plate is welded to the left side of the inner wall of the discharge pipe, the left end of the spiral conveying rod is rotatably connected to the support plate, a DC motor is fixedly installed on the right side of the transfer tank, and the right end of the spiral conveying rod passes through to the right side of the transfer tank and is fixedly connected to the output shaft of the DC motor.

[0007] Preferably, the feeding assembly includes a vibrating table located above the base plate, with supporting pulleys fixedly installed on the front and rear sides of the bottom of the vibrating table, and guide rails welded to the front and rear sides of the top of the base plate, with the supporting pulleys tumblingly connected to the inner cavity of the guide rails.

[0008] Preferably, a transmission rod is rotatably connected to both sides of the top of the base plate, and a winch is rotatably connected to the front and rear ends of the transmission rod. A steel wire traction rope is sleeved on the surface of the two winches on both sides, and the steel wire traction rope is fixedly connected to the vibration table.

[0009] Preferably, a second stepper motor is fixedly installed on the left side of the back surface of the base plate, the output shaft of the second stepper motor is fixedly connected to the transmission rod located on the left side, a hoisting platform is placed on the top of the vibration table, and the air-raid shelter door frame is placed in the inner cavity of the hoisting platform.

[0010] A pouring method for a concrete air-raid shelter door pouring device, the pouring method is as follows:

[0011] First, before watering, the user first uses a hoisting device to suspend the hoisting platform containing the air defense door frame on top of the vibrating table. Then, the user turns on the second stepper motor, which drives the left transmission rod to rotate, causing the two winches on the left to rotate. Then, under the action of the four winches, the steel wire traction rope rotates. During the rotation of the steel wire traction rope, the vibrating table is displaced to the right. At the same time, the support pulley rolls in the inner cavity of the guide rail. After the air defense door frame is brought to the bottom of the rectangular through hole, the second stepper motor stops running. At this time, the vibrating table is turned on, which causes the vibrating table to vibrate and the hoisting platform and air defense door frame on top of it to resonate.

[0012] Second, the user pours concrete into the inner cavity of the transfer tank through the bucket and turns on the DC motor at the same time. The DC motor drives the screw conveyor to rotate. Under the rotation of the screw conveyor, the concrete is spirally pushed to the left, so that the concrete in the inner cavity of the transfer tank passes through the inner cavity of the discharge pipe and the telescopic pipe to reach the inner cavity of the air defense door frame. At the same time, the vibrating table makes the concrete settle quickly and fill the inner cavity of the air defense door frame.

[0013] 3. During the concrete pouring process, the user turns on the stepper motor, which drives the drive gear to rotate. Under the combined action of the drive gear and the force ring, the material tank rotates on the top of the support frame, which in turn causes the discharge pipe and the telescopic pipe to rotate, allowing the front and rear pouring positions of the telescopic pipe to be adjusted. The rotational deviation generated during the rotation of the discharge pipe and the telescopic pipe can be adjusted by the relative sliding action of the discharge pipe and the telescopic pipe. This rotation ensures that the concrete is poured evenly into all positions inside the frame of the air-raid shelter.

[0014] Fourth, while watering, the user adjusts the left and right position of the telescopic pipe. During adjustment, the user activates the propulsion cylinders. The two propulsion cylinders push the displacement slide plate to the left. As the displacement slide plate slides on the surface of the limit guide rail, it drives the connecting rod to move to the left, which in turn pulls the telescopic pipe, allowing the watering position of the telescopic pipe to be further adjusted.

[0015] The beneficial effects of the present invention are as follows: The present invention uses the base plate and the feeding component together to transport the air defense door frame to the designated pouring position. Then, by setting the pouring component, concrete is poured into the inner cavity of the air defense door frame. At the same time, the use of the pouring component and the propulsion component together can adjust the front and rear pouring position and the left and right pouring position, so as to achieve the purpose of accurate pouring position, smooth material feeding and easy adjustment of pouring angle.

Through the setting of the feeding assembly 5, the second stepper motor 57, the winch 55 and the steel wire traction rope 56 work together to pull the vibration table 51. At the same time, the vibration table 51 vibrates the concrete in the inner cavity of the air defense door frame 3, so that the concrete can actively sink downward. With the cooperation of the support pulley 52 and the guide rail 53, the vibration table 51 is supported and guided, so that the vibration table 51 can move along the specified path. Example

[0030] Reference Figure 1 , 5 Similar to Embodiment 1, but with a further improvement: the propulsion assembly 6 includes a propulsion cylinder 61 fixedly installed on the front and rear sides of the top of the support frame 1; a slidable displacement slide plate 62 is provided on the left side of the top of the support frame 1, which is connected to the output end of the propulsion cylinder 61; a connecting rod 64 is fixedly connected to the left side of the bottom of the telescopic tube 46; an arc-shaped groove 65 adapted to the connecting rod 64 is opened on the top of the displacement slide plate 62; the connecting rod 64 is slidably connected to the inner cavity of the arc-shaped groove 65; and the left side of the top of the support frame 1... Limiting guide rails 63 are welded to both the front and rear ends of the side. The displacement slide plate 62 is slidably connected to the surface of the limiting guide rails 63. A rectangular through hole 66 is opened on the left side of the top of the support frame 1. The air defense door frame 3 is located directly below the inner cavity of the rectangular through hole 66.

[0031] A pouring method for a concrete air-raid shelter door pouring device, the pouring method is as follows:

[0032] First, before watering, the user first uses a hoisting device to hoist the hoisting platform 58 containing the air defense door frame 3 onto the top of the vibrating table 51. Then, the user turns on the second stepper motor 57, which drives the left transmission rod 54 to rotate, causing the two winches 55 on the left to rotate. Then, under the action of the four winches 55, the steel wire traction rope 56 rotates. During the rotation, the steel wire traction rope 56 drives the vibrating table 51 to move to the right. At the same time, the support pulley 52 rolls in the inner cavity of the guide rail 53, driving the air defense door frame 3 to the bottom of the rectangular through hole 66. Then, the second stepper motor 57 stops running. At this time, the vibrating table 51 is turned on, causing the vibrating table 51 to vibrate, and at the same time, the hoisting platform 58 and the air defense door frame 3 on top of it to resonate.

[0033] Second, the user pours concrete into the inner cavity of the transfer tank 41 through the bucket, and at the same time turns on the DC motor 49. The DC motor 49 drives the screw conveyor 47 to rotate. Under the rotation of the screw conveyor 47, the concrete is spirally pushed to the left, so that the concrete in the inner cavity of the transfer tank 41 passes through the inner cavity of the discharge pipe 45 and the telescopic pipe 46 to reach the inner cavity of the air defense door frame 3. At the same time, the vibrating table 51 makes the concrete settle quickly and fill the inner cavity of the air defense door frame 3.

[0034] 3. During the concrete pouring process, the user turns on the stepper motor 43, which drives the drive gear 44 to rotate. Under the combined action of the drive gear 44 and the force-bearing gear ring 42, the material transfer tank 41 rotates on the top of the support frame 1, which in turn causes the discharge pipe 45 and the telescopic pipe 46 to rotate, thereby adjusting the front and rear pouring positions of the telescopic pipe 46. The rotational deviation generated during the rotation of the discharge pipe 45 and the telescopic pipe 46 can be adjusted by the relative sliding action of the discharge pipe 45 and the telescopic pipe 46. This rotation ensures that the concrete is poured evenly into all positions inside the cavity of the air-raid shelter door frame 3.

[0035] Fourth, while watering, the user adjusts the left and right position of the telescopic pipe 46. During adjustment, the user activates the push cylinder 61. The two push cylinders 61 push the displacement slide plate 62 to the left. While the displacement slide plate 62 slides on the surface of the limit guide rail 63, it drives the connecting rod 64 to move to the left, which in turn pulls the telescopic pipe 46, allowing the watering position of the telescopic pipe 46 to be further adjusted.

[0036] In summary, this concrete blast door pouring device and method, through the combined use of the base plate 2 and the feeding component 5, transports the blast door frame 3 to the designated pouring position. Then, through the setting of the pouring component 4, concrete is poured into the inner cavity of the blast door frame 3. At the same time, the combined use of the pouring component 4 and the pushing component 6 allows for adjustment of the front and rear pouring positions as well as the left and right pouring positions, thereby achieving the purpose of accurate pouring position, smooth material feeding, and easy adjustment of the pouring angle.

[0037] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the invention to achieve the purpose of the invention.

6. A pouring method for a concrete air-raid shelter door pouring device, which is applied to the concrete air-raid shelter door pouring device according to claim 5, characterized in that, The irrigation method is as follows: First, before watering, the user first uses a hoisting device to hoist the hoisting platform (58) on which the air defense door frame (3) is placed on the top of the vibrating table (51). Then the user turns on the second stepper motor (57). The second stepper motor (57) drives the left transmission rod (54) to rotate, causing the two winches (55) on the left to rotate. Then, under the action of the four winches (55), the steel wire traction rope (56) rotates. During the rotation, the steel wire traction rope (56) drives the vibrating table (51) to move to the right. At the same time, the support pulley (52) rolls in the inner cavity of the guide rail (53). After the air defense door frame (3) reaches the bottom of the rectangular through hole (66), the second stepper motor (57) stops running. At this time, the vibrating table (51) is turned on, causing the vibrating table (51) to vibrate. At the same time, the hoisting platform (58) on top of it and the air defense door frame (3) resonate. Second, the user pours concrete into the inner cavity of the transfer tank (41) through the bucket and turns on the DC motor (49) at the same time. The DC motor (49) drives the screw conveyor (47) to rotate. Under the rotation of the screw conveyor (47), the concrete is spirally pushed to the left, so that the concrete in the inner cavity of the transfer tank (41) passes through the inner cavity of the discharge pipe (45) and the telescopic pipe (46) to reach the inner cavity of the air defense door frame (3).

3. During the concrete pouring process, the user turns on the stepper motor (43), which drives the drive gear (44) to rotate. Under the combined action of the drive gear (44) and the force-bearing gear ring (42), the material transfer tank (41) rotates on the top of the support frame (1), which in turn causes the discharge pipe (45) and the telescopic pipe (46) to rotate, so that the front and rear pouring positions of the telescopic pipe (46) can be adjusted. The rotation deviation generated during the rotation of the discharge pipe (45) and the telescopic pipe (46) can be adjusted by the relative sliding action of the discharge pipe (45) and the telescopic pipe (46). The rotation here can ensure that the concrete is evenly poured into each position of the cavity of the air defense door frame (3). Fourth, while watering, the user adjusts the left and right position of the telescopic pipe (46) during the watering. When adjusting, the user turns on the push cylinder (61). The two push cylinders (61) push the displacement slide plate (62) to the left. While the displacement slide plate (62) slides on the surface of the limit guide rail (63), it drives the connecting rod (64) to move to the left, which in turn pulls the telescopic pipe (46), so that the watering position of the telescopic pipe (46) can be further adjusted.
