Description

Technical Field

[0001] The present invention relates to the field of prefabricated building component production, in particular to a prefabricated building component maintenance device. Background Art

[0002] With the development of modern industrial technology, building can now be manufactured in batches and complete sets, similar to machine production. Some or all of the building components are prefabricated in a factory, then transported to the construction site and assembled into the designed house using reliable connections. Prefabricated components require curing after pouring concrete. Natural curing takes a long time, so manufacturers generally use steam curing to shorten the curing cycle. Current steam curing equipment includes vertical kilns, pit kilns, and tunnel kilns. Pit kilns operate intermittently, while vertical kilns and tunnel kilns can operate continuously. However, tunnel kilns have high investment costs, so vertical kilns are generally used for steam curing to improve production efficiency.

[0003] However, when existing vertical kilns are in use, hot steam is mostly sprayed from the bottom or top of the vertical kiln for curing, resulting in uneven curing of prefabricated building components and poor curing effect. At the same time, it is inconvenient to adjust the space of the vertical kiln and the amount of hot steam sprayed according to the number of prefabricated building components, which is not energy-saving and environmentally friendly. Moreover, if the cabinet door is opened during the hot steam curing process, not only will heat be dissipated, but it is also easy to cause harm to the operator. This is not energy-saving, environmentally friendly, or safe and reliable. Summary of the Invention

[0015] Beneficial effects of the present invention:

[0016] (1) The present invention provides a device for maintaining prefabricated building components. By providing a supporting mechanism, a supporting frame is inserted into a base through a sliding mechanism. Then, the prefabricated building components are inserted between the first supporting plate and the second supporting plate of each layer. The number of layers of the supporting frame can be adjusted according to the number of prefabricated building components to be maintained. The device is more convenient to use and more practical. Moreover, when it is necessary to place prefabricated building components of larger specifications, it is only necessary to remove the middle frame in the supporting frame of that layer, thereby facilitating the placement of prefabricated building components of different sizes. The device is more convenient to use and more practical.

[0017] (2) The present invention provides a device for maintaining prefabricated building components. By setting a control mechanism, etc., during maintenance, the steam generator is started, and the hot steam generated enters the first connecting pipe after passing through the steam supply pipe and the working box, and is sprayed on the surface of the prefabricated building components through the first steam hole at the bottom, the second steam hole at the top, and the third steam hole at the side wall, so that the hot steam is sprayed more tightly and evenly, and the maintenance effect on the prefabricated building components is better. In addition, when the side frame is inserted, it abuts against the sliding rod, so that the sliding rod slides on the inclined surface and squeezes the connecting block so that the sliding bar moves toward the fixed rod. At the same time, the first spring contracts. At this time, the through hole is aligned with the third steam hole, that is, in the normal state, the third steam hole is in a closed state. When the support frame and the prefabricated building components are placed on the layer, the third steam hole of the layer will be in an open state to ensure the ejection of hot steam. The number of the third steam holes opened is automatically adjusted as the number of maintenance layers changes, which is more energy-saving and environmentally friendly.

[0018] (3) The present invention provides a prefabricated building component maintenance device. By setting a height adjustment mechanism, etc., the motor is started. The rotation of the motor drives the rotation of the threaded rod, so that the first sleeve slides along the first sleeve, and then drives the movement of the second fixed plate and the upper cabinet. The height of the upper cabinet is adjusted according to the number of layers of the prefabricated building components, so that the hot steam ejected from the second steam hole has a better maintenance effect on the prefabricated building components. In addition, the internal space of the maintenance cabinet is adjusted to be more energy-saving and environmentally friendly.

[0019] (4) The present invention provides a prefabricated building component maintenance device. By setting a locking mechanism, etc., during maintenance, the hot steam generated passes through the steam supply pipe and the working box and enters the first connecting pipe. When the hot steam enters the working box, it impacts the surface of the rotary fan to rotate it. The rotation of the rotary fan drives the rotation of the second rotating shaft and the active bevel gear, and then drives the rotation of the driven bevel gear and the first rotating shaft. The rotation of the first rotating shaft drives the rotation of the fixed ring and the gravity ball, so that the gravity ball pushes the movable plate to move toward the support block under the action of centrifugal force, and the pin is inserted into the socket to lock the cabinet door to a limit position, ensuring that the cabinet door cannot be opened during the hot steam maintenance process, avoiding the operator from being scalded by hot gas, and at the same time, avoiding the dissipation of hot steam, which is safer, more reliable, more energy-saving and environmentally friendly.

At the same time, the internal space of the maintenance cabinet and the amount of hot steam sprayed can be adjusted according to the number of prefabricated building components to be maintained, which is more energy-saving and environmentally friendly. In addition, it is ensured that the cabinet door 11 is locked and limited during the hot steam maintenance process. At this time, the cabinet door 11 cannot be opened to prevent the operator from being scalded by hot air. At the same time, the dissipation of hot steam is avoided, which is safer, more reliable, more energy-saving and environmentally friendly.

When the motor 205 is started, the rotation of the motor 205 drives the rotation of the threaded rod 204, so that the first sleeve 206 slides along the first sleeve 207, thereby driving the movement of the second fixed plate 201 and the upper cabinet 102, thereby adjusting the height of the upper cabinet 102 according to the number of layers of the prefabricated building components, so that the hot steam ejected from the second steam hole 14 has a better maintenance effect on the prefabricated building components, and adjusts the internal space of the maintenance cabinet, which is more energy-saving and environmentally friendly.

[0036] The supporting mechanism includes a base 301 fixedly connected to a plurality of arrays arranged at the bottom of the lower cabinet 101, and the upper side wall of the base 301 is connected to a multi-layer supporting frame through a sliding mechanism. Each layer of the supporting frame includes two symmetrically arranged side frames 302 and an intermediate frame 303, and each layer of the supporting frames is connected by a sliding mechanism. The side walls of each side frame 302 are fixedly connected to two symmetrically arranged first supporting plates 304, and the two opposite side walls of each intermediate frame 303 are fixedly connected to four second supporting plates 305 symmetrically arranged in pairs. The supporting frame is inserted into the base 301 through the sliding mechanism, and then the prefabricated building components are inserted between the first supporting plates 304 and the second supporting plates 305 of each layer. The number of layers of the supporting frame can be adjusted according to the number of prefabricated building components to be maintained, which is more convenient to use and more practical. Moreover, when it is necessary to place prefabricated building components of larger specifications, it is only necessary to remove the intermediate frame 303 in the supporting frame of that layer, so as to facilitate the placement of prefabricated building components of different sizes, which is more convenient to use and more practical.

[0037] The sliding mechanism includes a sliding groove 401, and a sliding plate 402 is slidably connected in the sliding groove 401. The sliding plate 402 is fixed to the lower side wall of the support bracket to guide and limit the movement of the support bracket.

[0038] The control mechanism is slidably connected to the sliding bar 501 in each strip opening 22, and the sliding bar 501 is connected to the side wall of the strip opening 22 through a reset mechanism. The side wall of each sliding bar 501 is provided with a plurality of through holes 502 arranged in an array, and the side wall of each strip opening 22 is provided with a first pushing mechanism for pushing the sliding bar 501 to move. When the side frame 302 is inserted, the first pushing mechanism pushes the sliding bar 501 to move toward the fixed rod 601, so that the through hole 502 is aligned with the third steam hole 23, that is, in a normal state.

[0039] The reset mechanism includes two symmetrically arranged fixing rods 601 inserted on the side wall of the sliding bar 501, and the other end of the fixing rod 601 is fixed to the side wall of the strip opening 22. The side wall of the fixing rod 601 is sleeved with a first spring 602, which guides and resets the movement of the sliding bar 501.

[0040] The first pushing mechanism includes a fixed block 701 fixedly connected to the side wall of the strip-shaped opening 22, and a sliding rod 702 is inserted into the side wall of the fixed block 701, and the sliding bar 501 is fixedly connected to the side wall away from the fixed rod 601 with a connecting block 703, the connecting block 703 includes an inclined surface 704, and one end of the sliding rod 702 slides on the inclined surface 704. When the side frame 302 is inserted, it abuts against the sliding rod 702, so that the sliding rod 702 slides on the inclined surface 704 and squeezes the connecting block 703 to make the sliding bar 501 move toward the direction close to the fixed rod 601. At the same time, the first spring 602 contracts. At this time, the through hole 502 is aligned with the third steam hole 23.

[0041] The locking mechanism includes a support block 801 fixedly connected to the side wall of the cabinet door 11, and the side wall of the support block 801 is provided with a socket 806, and two symmetrically arranged moving rods 802 are inserted into the side wall of the support block 801, and the other end of the moving rod 802 is fixedly connected to a moving plate 804, and the side wall of the moving rod 802 is sleeved with a second spring 803, and the side wall of the moving plate 804 is fixedly connected with a pin 805, and the movement of the moving plate 804 is pushed by the second pushing mechanism, and the pin 805 is inserted into the socket 806, thereby locking and limiting the cabinet door 11 to ensure that the cabinet door 11 cannot be opened during the hot steam maintenance process, thereby preventing the operator from being scalded by hot steam and, at the same time, preventing the dissipation of hot steam, which is safer, more reliable, more energy-saving and environmentally friendly.

[0042] The second pushing mechanism includes a first rotating shaft 901 rotatably connected to the side wall of the lower cabinet 101, and the side wall fixed sleeve of the first rotating shaft 901 is provided with a fixing ring 902, and the side wall of the fixing ring 902 is fixedly connected with a plurality of second sleeves 904 arranged in an array, and a second set of rods 905 is connected to the second sleeve 904 through a reset spring, and the other end of the second set of rods 905 is fixedly connected to a gravity ball 903, and the gravity ball 903 slides on the side wall of the movable plate 804. The rotation of the first rotating shaft 901 is driven by the driving mechanism, and the rotation of the first rotating shaft 901 drives the rotation of the fixing ring 902 and the gravity ball 903, so that the gravity ball 903 pushes the movable plate 804 to move toward the direction close to the support block 801 under the action of centrifugal force, and inserts the pin 805 into the socket 806.

[0043] The driving mechanism includes a rotary fan 1001 arranged in the working box 20, and the rotary fan 1001 is rotatably connected to the side wall of the working box 20 through the second rotating shaft 1002. One end of the second rotating shaft 1002 passes through the side wall of the working box 20 and is fixedly connected to the driving bevel gear 1003. The end of the first rotating shaft 901 is fixedly connected to the driven bevel gear 1004, and the driven bevel gear 1004 is meshed with the driving bevel gear 1003. During maintenance, the hot steam generated passes through the steam supply pipe 19 and the working box 20 and enters the first connecting pipe 21. When the hot steam enters the working box 20, it impacts the surface of the rotary fan 1001 and causes it to rotate. The rotation of the rotary fan 1001 drives the rotation of the second rotating shaft 1002 and the driving bevel gear 1003, thereby driving the rotation of the driven bevel gear 1004 and the first rotating shaft 901.

[0044] Working principle: During operation, first, the support frame is inserted into the base 301 through the sliding mechanism. Then, the prefabricated building components are inserted between the first support plate 304 and the second support plate 305 of each layer. The number of layers of the support frame can be adjusted according to the number of prefabricated building components to be maintained, making it more convenient to use and more practical. Moreover, when it is necessary to place prefabricated building components of larger specifications, it is only necessary to remove the middle frame 303 in the support frame of that layer, thereby facilitating the placement of prefabricated building components of different sizes, making it more convenient to use and more practical.

[0045] At the same time, the motor 205 is started. The rotation of the motor 205 drives the rotation of the threaded rod 204, causing the first sleeve 206 to slide along the first sleeve rod 207, thereby driving the movement of the second fixing plate 201 and the upper cabinet 102, thereby adjusting the height of the upper cabinet 102 according to the number of layers of the prefabricated building components, so that the hot steam ejected from the second steam hole 14 has a better curing effect on the prefabricated building components, and adjusting the internal space of the curing cabinet body, which is more energy-saving and environmentally friendly;

[0046] Next, during maintenance, the steam generator 17 is started, and the hot steam generated enters the first connecting pipe 21 after passing through the steam supply pipe 19 and the working box 20, and is sprayed onto the surface of the prefabricated building component through the first steam hole 13 at the bottom, the second steam hole 14 at the top, and the third steam hole 23 on the side wall, so that the hot steam is sprayed more tightly and evenly, and the maintenance effect of the prefabricated building component is better. In addition, when the side frame 302 is inserted, it abuts against the sliding rod 702, causing the sliding rod 702 to slide on the inclined surface 704 and squeeze the connecting block 703, so that the sliding bar 501 moves toward the fixed rod 601. At the same time, the first spring 602 contracts. At this time, the through hole 502 is aligned with the third steam hole 23, that is, in the normal state, the third steam hole 23 is in a closed state. When the support frame and prefabricated building components are placed on this layer, the third steam hole 23 of this layer will be in an open state to ensure the spraying of hot steam. The number of the third steam holes 23 opened is automatically adjusted as the number of curing layers changes, which is more energy-saving and environmentally friendly.

[0047] In addition, during maintenance, the hot steam generated enters the first connecting pipe 21 after passing through the steam supply pipe 19 and the working box 20. When the hot steam enters the working box 20, it impacts the surface of the rotary fan 1001 to rotate it. The rotation of the rotary fan 1001 drives the rotation of the second rotating shaft 1002 and the active bevel gear 1003, and then drives the rotation of the driven bevel gear 1004 and the first rotating shaft 901. The rotation of the first rotating shaft 901 drives the rotation of the fixed ring 902 and the gravity ball 903, so that the gravity ball 903 pushes the movable plate 804 to move toward the support block 801 under the action of centrifugal force, and inserts the pin 805 into the socket 806, thereby locking the cabinet door 11 to ensure that the cabinet door 11 cannot be opened during the hot steam maintenance process, avoiding the operator from being scalded by hot gas, and at the same time, avoiding the dissipation of hot steam, which is safer, more reliable, more energy-saving and environmentally friendly.
