TECHNICAL FIELD
[0001] The application relates to the technical field of steel fireproof door production, in particular to a three-dimensional transfer device in a steel fireproof door production workshop. BACKGROUND
[0002] The steel fireproof door is a door specially designed for fire prevention, heat insulation and smoke prevention, and is usually used in the fireproof partition system of a building to effectively isolate the fire source and smoke, protect personnel evacuation and limit the spread of fire. The steel fireproof door is widely used in fireproof isolation and safety protection of residential buildings, commercial buildings, industrial facilities, hospitals, schools and other places. In order to avoid the accumulation of the produced steel fireproof door at the end of the production line in the steel fireproof door production workshop, a transfer device is needed to transfer the produced steel fireproof door to the storage place.
[0003] The device for transferring the steel fireproof door in the steel fireproof door production workshop mainly comprises a base, universal wheels installed at the bottom of the base, and a push frame installed on one side of the upper end of the base. The transfer device of this structure is used by first stacking the produced steel fireproof door on the base by the workers, then moving the base to the steel fireproof door storage place by the workers holding the push frame, and then stacking the steel fireproof door on the base on the designated position by the workers layer by layer, so as to realize the transfer of the steel fireproof door in the production workshop.
[0004] Although the existing transfer device in the steel fireproof door production workshop can assist the workers in transferring and stacking the steel fireproof door, the taking and placing of the steel fireproof door on the device during the transfer process is realized by the workers in the lifting manner, which not only increases the labor intensity of the workers, but also easily leads to the low transfer efficiency of the device for the produced steel fireproof door due to the slow speed of the workers. SUMMARY
[0005] In view of the deficiencies of the prior art, the purpose of the present application is to provide a three-dimensional transfer device in a steel fireproof door production workshop, which can realize the power-assisted conveying of the steel fireproof door to the device during the transfer process and the power-assisted removal of the steel fireproof door from the device.
[0006] The above application purpose of the present application is realized by the following technical scheme:
[0007] A three-dimensional transfer device for steel fire door production workshops includes a base. Two lifting mechanisms are symmetrically installed on both sides of the upper end of the base. Each lifting mechanism includes a U-shaped frame, a lifting plate, a screw, a driven gear, a double gear shaft, a driving gear, and a second motor. The U-shaped frame is bolted to the base. The second motor is located at the center of the bottom end of the U-shaped frame. The driving gear is located at the power output end of the second motor. There are two double gear shafts, symmetrically installed on both sides of the driving gear. Each double gear shaft has a connection to a [missing information - likely a device or mechanism] at its end opposite to the driving gear. The driven gear has a screw installed at the middle of its upper end, and a lifting plate is installed on the screw. A storage frame is connected between the lifting plates of the two lifting mechanisms. The storage frame has a storage slot with one end open and the other closed. Each storage slot is equipped with a power-assisted guiding mechanism, which includes a double-cylinder roller, a conveyor belt, and a motor. The double-cylinder roller is installed in the storage slot, and the conveyor belt is sleeved on the outside of the double-cylinder roller. The lifting plate is also equipped with connecting bolts to fix the storage frame.
[0008] Optionally, two push handles are installed on the U-shaped frame of each of the two lifting mechanisms, and an operation panel is installed on the U-shaped frame of one of the lifting mechanisms. A battery is installed on the side wall of the U-shaped frame adjacent to the operation panel.
[0009] Optionally, the operation panel is electrically connected to the first motor, the second motor, and the battery.
[0010] Optionally, a caster wheel with a wheel lock is bolted to each of the four corners of the base.
[0011] Optionally, the driving gear is connected to the motor coupling, one end of the dual-gear shaft meshes with the driving gear, and the other end of the dual-gear shaft meshes with the driven gear.
[0012] Optionally, the U-shaped frame located at the double gear shaft has a hollow structure, and the part of the U-shaped frame that mates with the lifting plate has a concave structure.
[0013] Optionally, the screw is rotatably connected to the U-shaped frame, and the screw passes through the lifting plate and is threadedly engaged with the lifting plate.
[0014] Optionally, each of the aided guiding mechanisms has no fewer than eight twin-cylinder rollers, and the twin-cylinder rollers are rotatably engaged with the receiving groove.
[0015] Optionally, the first motor is connected to the corresponding double-cylinder roller coupling, and the first motor is bolted to the storage frame.
[0016] In summary, this application includes at least one of the following beneficial technical effects:
[0017] This invention, through the coordinated design of a lifting mechanism and an assisted guiding mechanism, enables the transfer of steel fire doors produced in the factory. First, the lifting mechanism, through the action of a motor, drive gear, double gear shaft, and driven gear, drives a screw. During the screw's rotation, the screw, under the action of threaded transmission, lifts the lifting plate, thereby raising the storage frame. This ensures that the height of the storage groove within the storage frame is consistent with the discharge end height of the steel fire door production line. After exiting the production line, the steel fire doors directly enter the storage groove and come into contact with the conveyor belt in the assisted guiding mechanism within the storage groove, facilitating assisted guiding. As the motor in the mechanism drives the corresponding double-cylinder rollers to rotate, the conveyor belt rotates, ensuring the automatic entry of the steel fire door into the storage tank. Similarly, when removing the steel fire door from the storage tank, simply reverse the motor, and the steel fire door will be moved out under the action of the conveyor belt. This facilitates convenient transfer and stacking by staff. Since the entry and exit of the steel fire door from the device are both automated during the above transfer process, the tedious manual operation of moving the steel fire door from the device is eliminated, resulting in less manual labor intensity and higher transfer efficiency during the transfer of steel fire doors.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.
[0025] To better understand the technical solutions presented in the embodiments of this application, the structure and working principle of the current steel fire door production plant transfer device will be introduced first.
[0026] Currently, the equipment used for transferring steel fire doors in steel fire door production workshops mainly consists of a base, casters installed at the four corners of the base, and a push frame installed on one side of the upper part of the base. When using this type of transfer device, workers first stack the produced steel fire doors layer by layer on the base. Then, workers use the push frame to move the base to the steel fire door stacking area. Finally, workers carry the steel fire doors layer by layer to the designated location, thereby realizing the transfer of steel fire doors within the production workshop.
[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 This application discloses a three-dimensional transfer device for steel fire door production workshops, comprising a base 4. Two lifting mechanisms 5 are symmetrically installed on both sides of the upper end of the base 4. Each lifting mechanism 5 includes a U-shaped frame 51, a lifting plate 52, a screw 53, a driven gear 54, a double gear shaft 55, a driving gear 56, and a second motor 57. The U-shaped frame 51 is bolted to the base 4. The second motor 57 is located at the middle of the bottom end of the U-shaped frame 51. The driving gear 56 is located at the power output end of the second motor 57. There are two double gear shafts 55, symmetrically installed on both sides of the driving gear 56, with each double gear shaft 55 facing away from the driving gear. Each wheel 56 is connected to a driven gear 54 at one end. A screw 53 is installed in the middle of the upper end of the driven gear 54, and a lifting plate 52 is installed on the screw 53. A storage frame 1 is connected between the lifting plates 52 of the two lifting mechanisms 5. A storage slot 2 with one end open and the other end closed is opened in the storage frame 1. A power-assisted guiding mechanism 8 is installed in each storage slot 2. The power-assisted guiding mechanism 8 includes a double-cylinder roller 81, a conveyor belt 82 and a motor 83. The double-cylinder roller 81 is installed in the storage slot 2, and the conveyor belt 82 is sleeved on the outside of the double-cylinder roller 81. A connecting bolt 9 for fixing the storage frame 1 is also installed on the lifting plate 52.
[0028] Specifically, when transferring the steel fire doors produced in the factory, the driving gear 56, the double gear shaft 55, and the driven gear 54 in the lifting mechanism 5 are first rotated by the motor 57. The driven gear 54 then drives the screw 53 to rotate, so that the lifting plate 52 is raised under the action of threaded transmission during the rotation of the screw 53. This raises the storage frame 1, ensuring that the height of the storage slot 2 inside the storage frame 1 is consistent with the height of the discharge end of the steel fire door production line. During the production of the steel fire doors... After exiting the online system, the steel fire door will directly enter the storage tank 2 and come into contact with the conveyor belt 82 in the auxiliary guiding mechanism 8 inside the storage tank 2. This allows the conveyor belt 82 to rotate as the motor 83 in the auxiliary guiding mechanism 8 drives the corresponding double-cylinder roller 81 to rotate, ensuring the automatic entry of the steel fire door into the storage tank 2. Similarly, when removing the steel fire door from the storage tank 2, simply reverse the motor 83, and the steel fire door can be removed under the action of the conveyor belt 82, facilitating convenient transfer and stacking by staff.
[0029] Please see Figure 1 and Figure 2 Two push handles 7 are installed on the U-shaped frame 51 of each of the two lifting mechanisms 5. An operation panel 6 is installed on the U-shaped frame 51 of one of the lifting mechanisms 5. A storage battery 10 is installed on the side wall of the U-shaped frame 51 adjacent to the operation panel 6.
[0030] As one implementation, the hand-held push handle 7 provides a force-applying part when the device is moved, facilitating convenient movement of the device. The storage battery 10 is mainly used to power motor 1 83 and motor 2 57 to ensure the normal operation of motor 1 83 and motor 2 57.
[0031] Please see Figures 1-4 The control panel 6 is electrically connected to motor 1 83, motor 2 57 and battery 10.
[0032] As one implementation method, the operation panel 6 mainly functions as a master switch, controlling the on / off state of the control circuit to achieve coordinated start and stop of motor 1 83 and motor 2 57.
[0033] Please see Figure 1 and Figure 2 At the four corners of the bottom of the base 4, there is a universal wheel 3 with a wheel lock connected by bolts.
[0034] As one implementation method, the casters 3 are mainly used to facilitate the movement of the base 4. They are also equipped with wheel locks to provide convenient braking after the base 4 is moved to a designated position, thus preventing the device from moving during loading and unloading.
[0035] Please see Figure 3The driving gear 56 is connected to the motor 57 via a coupling. One end of the double gear shaft 55 meshes with the driving gear 56, and the other end of the double gear shaft 55 meshes with the driven gear 54.
[0036] In one implementation, motor 57 is mainly used to drive the drive gear 56 to rotate. After the drive gear 56 rotates, it will transmit power to the driven gear 54 under the action of the double gear shaft 55, thereby realizing the rotation of the driven gear 54.
[0037] Please see Figure 3 The U-shaped frame 51 has a hollow structure located at the double gear shaft 55, and the part of the U-shaped frame 51 that mates with the lifting plate 52 has a concave structure.
[0038] As one implementation method, the hollow structure design provides sufficient installation space within the U-shaped frame 51 for the double gear shaft 55, the driving gear 56, and the driven gear 54, ensuring reliable installation of the double gear shaft 55, the driving gear 56, and the driven gear 54. The concave structure design provides a certain installation space for the screw 53 and also guides the lifting plate 52 during lifting.
[0039] Please see Figures 1-3 The screw 53 is rotatably connected to the U-shaped frame 51, and the screw 53 passes through the lifting plate 52 and is threadedly engaged with the lifting plate 52.
[0040] As one implementation method, the rotating installation method makes it easier for the screw 53 to rotate relative to the U-shaped frame 51, so that the lifting plate 52 can be stably lifted through the threaded transmission after the screw 53 rotates.
[0041] Please see Figure 4 and Figure 5 Each assistive guiding mechanism 8 has no fewer than eight double-cylinder rollers 81, and the double-cylinder rollers 81 are rotatably engaged with the storage groove 2.
[0042] As one implementation method, the rotating fit installation method makes it easier for the double-cylinder roller 81 to rotate relative to the receiving groove 2, while the double-cylinder roller 81 also serves to support the conveyor belt 82.
[0043] Please see Figure 1 , Figure 4 and Figure 5 Motor 83 is connected to the corresponding double-cylinder roller 81 coupling, and motor 83 is bolted to the storage frame 1.
[0044] In one implementation, motor 83 is mainly used to provide power to the double-cylinder roller 81 so that the double-cylinder roller 81 rotates to drive the conveyor belt 82 to rotate, so as to facilitate the entry and exit of the steel fire door from the storage slot 2.
[0045] The specific working principle is as follows: When transferring the steel fire doors produced in the factory, the device is first moved to the discharge end of the steel fire door production line. Under the action of motor 57 in the lifting mechanism 5, the driving gear 56, double gear shaft 55, and driven gear 54 rotate. After the driven gear 54 rotates, it drives the screw 53 to rotate. During the rotation of the screw 53, the lifting plate 52 is lifted under the action of threaded transmission, thereby lifting the storage frame 1. This ensures that the height of the storage groove 2 in the storage frame 1 is consistent with the height of the discharge end of the steel fire door production line. After the steel fire door comes out of the production line, it will directly enter the storage groove 2 and interact with the auxiliary guiding mechanism 8 in the storage groove 2. The conveyor belt 82 contacts the corresponding double-cylinder roller 81 driven by the motor 83 in the assisted guiding mechanism 8, thereby enabling the conveyor belt 82 to rotate and ensuring the automatic entry of the steel fire door into the storage tank 2. Similarly, when removing the steel fire door from the storage tank 2, simply reverse the motor 83 to remove the steel fire door under the action of the conveyor belt 82, facilitating convenient transfer and stacking by staff. Since the entry and exit of the steel fire door from the device are both automatic during the above transfer process, the tedious manual operation of moving the steel fire door from the device is eliminated, resulting in less manual labor intensity and higher transfer efficiency during the transfer of steel fire doors.
[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
