Description

Technical Field

[0001] The invention relates to a lightweight earthquake-resistant prefabricated cabin, in particular to a lightweight earthquake-resistant prefabricated cabin, and belongs to the technical field of lightweight earthquake-resistant prefabricated cabins. Background Art

[0002] As a building component pre-assembled in the factory, the prefabricated cabin can be quickly installed on site, greatly shortening the construction period. This high efficiency makes the prefabricated cabin widely used in residential buildings, commercial buildings and public buildings. The use of lightweight materials not only reduces the overall weight of the prefabricated cabin, but also improves its bearing capacity and seismic performance. Since the prefabricated cabin is designed with more supporting mechanisms, the seismic effect is also more significant.

[0003] The existing lightweight earthquake-resistant prefabricated cabin has a fixed structure. Since the prefabricated cabin is usually manufactured in advance and then transported to the required site for use, the bottom of the cabin will come into contact with the transport carriage during transportation. It is easy for the cabin to be transferred into the prefabricated cabin through the carriage due to bumps, which can easily cause the prefabricated cabin body to loosen during assembly and cause damage to the prefabricated cabin body.

[0004] Therefore, there is an urgent need to improve a lightweight earthquake-resistant prefabricated cabin to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a lightweight and earthquake-resistant prefabricated cabin body. By setting up a supporting structure, the friction between the bottom of the prefabricated cabin body and the carriage of the transport vehicle during transportation is avoided, thereby preventing the vibration caused by the bumps from being transmitted to the interior of the prefabricated cabin body. After the prefabricated cabin body is installed in the carriage of the transport vehicle, multiple drive motors are started at the same time to drive the first gear to rotate, and the second gear also starts to rotate under the drive of the first gear. At this time, the screw rod rotates under the drive of the second gear to move the push block downward. During the descent process, the push block pushes the supporting leg downward until the shock absorber at the bottom of the supporting leg contacts the carriage. Since the descent length of the push block is exactly the descent distance of the supporting leg, the push block will not detach from the screw rod. After the shock absorber contacts the carriage, the prefabricated cabin can be prevented from being vibrated and resulting in loose assembly, thereby preventing the prefabricated cabin body from being damaged.

[0006] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0007] A lightweight, earthquake-resistant prefabricated cabin body comprises a prefabricated cabin body and a cover plate, wherein a support structure is arranged on the prefabricated cabin body, and the support structure comprises a driving motor fixedly mounted on the top of the cover plate, a first gear fixedly mounted on the output end of the driving motor, a plurality of first fixing plates fixedly mounted on the side of the prefabricated cabin body, a screw rod movably mounted on the first fixing plate, a second gear meshing with the first gear fixedly mounted on one end of the screw rod, a push block movably mounted on the other end of the screw rod, a second fixing plate connected to the prefabricated cabin body is mounted below the push block, a support leg connected to the push block is mounted on the second fixing plate, and a shock absorber is arranged at the bottom of the support leg.

[0008] Preferably, a plurality of slide grooves are provided on the second fixing plate, and a sliding block connected to the supporting leg is movably installed inside the slide groove.

[0009] Preferably, a protective shell connected to the prefabricated cabin body is fixedly mounted on the outer side of the driving motor, a plurality of heat dissipation holes are opened on the protective shell, and an inspection cover is provided on one side of the protective shell.

[0012] Preferably, a plurality of limiting rods are fixedly mounted on the bottom of the hot air conveying pipe and the cold air conveying pipe, and a plurality of limiting holes adapted to the limiting rods are opened on the air inlet.

[0013] Preferably, a plurality of sleeves are provided at the connection between the hot air delivery pipe and the air inlet, a plurality of first threaded holes are provided on the sleeves, and the sleeves are connected by a plurality of first bolts.

[0014] Preferably, a cabin door is provided on one side of the prefabricated cabin body, a protective cover is fixedly installed on the front of the cabin door, and an anti-slip handle is fixedly installed inside the protective cover.

[0015] Preferably, a baffle is movably mounted on the protective cover, a pull ball is fixedly mounted on the top of the baffle, a plurality of second threaded holes are opened on the protective cover, and a second bolt connected to the baffle is installed on the protective cover.

[0017] The present invention has at least the following beneficial effects:

[0018] By setting up the supporting structure, the bottom of the prefabricated cabin body is prevented from rubbing against the carriage of the transport vehicle during transportation, thereby preventing the vibration caused by the bumps from being transmitted to the interior of the prefabricated cabin body. After the prefabricated cabin body is loaded into the carriage of the transport vehicle, multiple drive motors are started at the same time to drive the first gear to rotate, and the second gear also starts to rotate driven by the first gear. At this time, the screw rod rotates driven by the second gear to move the push block downward, and the push block pushes the supporting leg downward during the descent process until the shock absorber at the bottom of the supporting leg contacts the carriage. Since the descent length of the push block is exactly the descent distance of the supporting leg, the push block will not detach from the screw rod. After the shock absorber contacts the carriage, the prefabricated cabin can be prevented from being vibrated and resulting in loose assembly, thereby preventing the prefabricated cabin body from being damaged.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] like Figure 1-Figure 8 As shown, this embodiment provides a lightweight earthquake-resistant prefabricated cabin embodiment.

[0031] A lightweight earthquake-resistant prefabricated cabin body, comprising a prefabricated cabin body 1 and a cover plate 2, wherein a support structure 3 is arranged on the prefabricated cabin body 1, and the support structure 3 comprises a driving motor 4 fixedly mounted on the top of the cover plate 2, and a first gear 5 is fixedly mounted on the output end of the driving motor 4, and a plurality of first fixing plates 6 are fixedly mounted on the side of the prefabricated cabin body 1, and a screw rod 7 is movably mounted on the first fixing plate 6, and a second gear 8 meshing with the first gear 5 is fixedly mounted on one end of the screw rod 7, and a push block 9 is movably mounted on the other end of the screw rod 7, and a second fixing plate 10 connected to the prefabricated cabin body 1 is installed below the push block 9, and a supporting leg 11 connected to the push block 9 is installed on the second fixing plate 10, and a shock absorber 12 is arranged at the bottom of the supporting leg 11. By setting the support structure 3, the prefabricated cabin body is avoided. During transportation, the bottom of the prefabricated cabin 1 rubs against the carriage of the transport vehicle, thereby preventing the vibration caused by the bumps from being transmitted to the interior of the prefabricated cabin body 1. After the prefabricated cabin body 1 is loaded into the carriage of the transport vehicle, multiple driving motors 4 are started at the same time to drive the first gear 5 to rotate, and the second gear 8 also starts to rotate under the drive of the first gear 5. At this time, the screw rod 7 rotates under the drive of the second gear 8 to move the push block 9 downward. During the descent process, the push block 9 pushes the support leg 11 downward until the shock absorber 12 at the bottom of the support leg 11 contacts the carriage. Since the descent length of the push block 9 is exactly the descent distance of the support leg 11, the push block 9 will not be detached from the screw rod 7. After the shock absorber 12 contacts the carriage, the prefabricated cabin can be prevented from being vibrated and thus causing looseness in assembly, thereby preventing the prefabricated cabin body 1 from being damaged.

[0032] like Figure 5 As shown, a plurality of slide grooves 13 are provided on the second fixed plate 10, and a slider 14 connected to the support leg 11 is movably installed inside the slide groove 13. Through the arrangement of the slide groove 13 and the slider 14, the friction between the support leg 11 and the second fixed plate 10 can be reduced, so that the second fixed plate 10 can slide downward more smoothly, which is convenient for the push block 9 to push the support leg 11, thereby saving the power consumption of the drive motor 4.

[0033] like Figure 4 As shown, a protective shell 15 connected to the prefabricated cabin body 1 is fixedly installed on the outer side of the drive motor 4, and a plurality of heat dissipation holes 16 are opened on the protective shell 15. An inspection cover 17 is arranged on one side of the protective shell 15. Through the arrangement of the protective shell 15, the heat dissipation holes 16 and the inspection cover 17, the drive motor 4 can be protected to prevent the drive motor 4 from being damaged by collision. The heat dissipation holes 16 can dissipate the heat generated by the operation of the drive motor 4 to prevent the heat inside the protective shell 15 from accumulating and affecting the drive motor 4. By opening the inspection cover 17, it is convenient for personnel to inspect the drive motor 4 without disassembling the entire protective shell 15.

[0034] like Figure 4As shown, a first magnetic ring 18 is fixedly installed at one end of the protective shell 15, and a second magnetic ring 19 magnetically connected to the first magnetic ring 18 is fixedly installed on one side of the inspection cover 17. Through the arrangement of the first magnetic ring 18 and the second magnetic ring 19, the inspection cover 17 can be fixed on the protective shell 15 after the first magnetic ring 18 and the second magnetic ring 19 are attracted to each other, so that a closed space is formed to protect the drive motor 4. Due to the characteristics of the first magnetic ring 18 and the second magnetic ring 19, the inspection cover 17 can be opened by directly pulling the inspection cover 17.

[0035] like Figure 6 As shown, a plurality of air inlets 20 are provided on the cover plate 2, and a hot air duct 21 and a cold air duct 22 are respectively connected above the air inlet 20. Through the provision of the air inlet 20, the hot air duct 21 and the cold air duct 22, since the prefabricated cabin body 1 has a significant anti-seismic effect and also has better internal sealing, the interior of the prefabricated cabin body 1 will be overcooled or overheated in a harsh environment. Through the plurality of air inlets 20 provided on the cover plate 2, the hot air duct 21 or the cold air duct 22 can be connected to the air inlet 20 according to the temperature change of the environment to provide heating or cooling to the interior of the prefabricated cabin body 1, so that the personnel inside the prefabricated cabin body 1 are more comfortable.

[0036] like Figure 6 As shown, a plurality of limiting rods 23 are fixedly installed at the bottom of the hot air duct 21 and the cold air duct 22, and a plurality of limiting holes 24 adapted to the limiting rods 23 are opened on the air inlet 20. By setting the limiting rods 23 and the limiting holes 24, when the hot air duct 21 and the cold air duct 22 are connected, the plurality of limiting rods 23 are inserted into the limiting holes 24, which can improve the stability of the connection between the two and prevent the hot air duct 21 and the cold air duct 22 from falling off from the air inlet 20.

[0037] like Figure 6 As shown, a plurality of ferrules 25 are sleeved at the connection between the hot air duct 21 and the air inlet 20, a plurality of first threaded holes 26 are opened on the ferrules 25, and the ferrules 25 are connected by a plurality of first bolts 27. By setting the ferrules 25, the first threaded holes 26 and the first bolts 27, after the hot air duct 21 or the cold air duct 22 is connected to the air inlet 20, the plurality of ferrules 25 are clamped at the connection between the two, and then the ferrules 25 are fixed with a plurality of first bolts 27, which can further improve the stability of the connection between the hot air duct 21 and the cold air duct 22 and the air inlet 20.

[0038] like Figure 7As shown, a hatch 28 is provided on one side of the prefabricated cabin body 1, a protective cover 29 is fixedly installed on the front of the hatch 28, and an anti-slip handle 30 is fixedly installed inside the protective cover 29. Through the arrangement of the hatch 28, the protective cover 29 and the anti-slip handle 30, pulling the anti-slip handle 30 to open the hatch 28 can facilitate personnel to enter and exit the prefabricated cabin body 1. The protective cover 29 can protect the anti-slip handle 30 when the prefabricated cabin body 1 is used outside, thereby preventing the anti-slip handle 30 from being eroded and damaged by rainwater, which makes it inconvenient to open the hatch 28.

[0039] like Figure 7 As shown, a baffle 31 is movably installed on the protective cover 29, a pull ball 32 is fixedly installed on the top of the baffle 31, a plurality of second threaded holes 33 are opened on the protective cover 29, and a second bolt 34 connected to the baffle 31 is installed on the protective cover 29. By setting the baffle 31, the pull ball 32, the second threaded hole 33 and the second bolt 34, the baffle 31 is pushed downward to the bottom of the protective cover 29, so as to further protect the anti-slip handle 30 and prevent the service life of the anti-slip handle 30 from being shortened due to wind and sun. The baffle 31 can be limited on the protective cover 29 by using a plurality of second bolts 34, so as to improve the stability of the baffle 31.

[0040] like Figure 6 and Figure 8 As shown, a protective sleeve 35 is sleeved on the air inlet 20, and a plurality of first magnetic blocks 36 are fixedly installed at the bottom of the protective sleeve 35. A plurality of grooves 37 adapted to the protective sleeve 35 are opened on the cover plate 2, and a second magnetic block 38 magnetically connected to the first magnetic block 36 is fixedly installed at the bottom of the groove 37. Through the arrangement of the protective sleeve 35, the first magnetic block 36, the groove 37 and the second magnetic block 38, the protective sleeve 35 can be sleeved on the air inlet 20 when the air inlet 20 is not in use to prevent rain or other dust from entering the interior of the prefabricated cabin body 1 through the air inlet 20. After the protective sleeve 35 is sleeved on the air inlet 20, the plurality of first magnetic blocks 36 at the bottom thereof are attracted to the plurality of second magnetic blocks 38 in the groove 37, which can improve the stability of the sleeve 35.

[0041] In this embodiment, if Figure 1-Figure 8 As shown, the working process of a lightweight earthquake-resistant prefabricated cabin provided in this embodiment is as follows:

[0042] After the prefabricated cabin body 1 is loaded into the interior of the carriage of the transport vehicle, multiple drive motors 4 are started at the same time to drive the first gear 5 to rotate, and the second gear 8 also starts to rotate driven by the first gear 5. At this time, the screw rod 7 rotates driven by the second gear 8 to move the push block 9 downward. During the descent process, the push block 9 pushes the support leg 11 downward until the shock absorber 12 at the bottom of the support leg 11 contacts the carriage. Since the descent length of the push block 9 is exactly the descent distance of the support leg 11, the push block 9 will not detach from the screw rod 7. After the shock absorber 12 contacts the carriage, the prefabricated cabin can be prevented from being vibrated and causing looseness in assembly, thereby preventing the prefabricated cabin body 1 from being damaged.

[0043] In summary, in this embodiment, according to a lightweight seismic prefabricated cabin of this embodiment, the friction between the support leg 11 and the second fixed plate 10 can be reduced by setting the slide groove 13 and the slider 14, so that the second fixed plate 10 can slide downward more smoothly, which is convenient for the push block 9 to push the support leg 11, thereby saving the power consumption of the drive motor 4. The protection shell 15, the heat dissipation holes 16 and the inspection cover 17 can be provided to protect the drive motor 4 to prevent the drive motor 4 from being damaged by collision. The heat dissipation holes 16 can dissipate the heat generated by the operation of the drive motor 4 to prevent the heat inside the protective shell 15 from accumulating and affecting the drive motor 4. By opening the inspection cover 17, it is convenient for personnel to inspect the drive motor 4. The motor 4 can be inspected and repaired without disassembling the entire protective shell 15. Through the arrangement of the first magnetic ring 18 and the second magnetic ring 19, the first magnetic ring 18 and the second magnetic ring 19 can be attracted to each other to fix the inspection cover 17 on the protective shell 15, so that a closed space is formed to protect the drive motor 4. Due to the characteristics of the first magnetic ring 18 and the second magnetic ring 19, the inspection cover 17 can be opened by directly pulling the inspection cover 17. Through the arrangement of the air inlet 20, the hot air duct 21 and the cold air duct 22, the prefabricated cabin body 1 has a significant anti-seismic effect and also has good internal sealing. Therefore, in harsh environments, the interior of the prefabricated cabin body 1 will be overcooled or overheated. Through the multiple air inlets 20 arranged on the cover plate 2, the air inlets 20 can be opened according to the temperature changes of the environment. The hot air duct 21 or the cold air duct 22 is connected to the air inlet 20 to provide heating or cooling to the interior of the prefabricated cabin body 1, making the personnel inside the prefabricated cabin body 1 more comfortable. By setting the limiting rods 23 and the limiting holes 24, when the hot air duct 21 is connected to the cold air duct 22, multiple limiting rods 23 are inserted into the limiting holes 24, which can improve the stability of the connection between the two and prevent the hot air duct 21 and the cold air duct 22 from falling off from the air inlet 20. By setting the ferrule 25, the first threaded hole 26 and the first bolt 27, after the hot air duct 21 or the cold air duct 22 is connected to the air inlet 20, multiple ferrules 25 are clamped at the connection between the two, and then the ferrules 25 are fixed with multiple first bolts 27. In order to further improve the stability of the connection between the hot air delivery pipe 21 and the cold air delivery pipe 22 and the air inlet 20, by setting the hatch 28, the protective cover 29 and the anti-slip handle 30, pulling the anti-slip handle 30 to open the hatch 28 can facilitate personnel to enter and exit the prefabricated cabin body 1. The protective cover 29 can protect the anti-slip handle 30 when the prefabricated cabin body 1 is used outside, and prevent the anti-slip handle 30 from being eroded and damaged by rain, thereby making it inconvenient to open the hatch 28. By setting the baffle 31, the pull ball 32, the second threaded hole 33 and the second bolt 34, the baffle 31 is pushed downward to the bottom of the protective cover 29, which can further protect the anti-slip handle 30 and prevent the anti-slip handle 30 from being shortened in the wind and sun.The baffle 31 can be limited on the protective cover 29 by using multiple second bolts 34, thereby improving the stability of the baffle 31. By setting the protective sleeve 35, the first magnetic block 36, the groove 37 and the second magnetic block 38, the protective sleeve 35 can be mounted on the air inlet 20 when the air inlet 20 is not in use, thereby preventing rain or other dust from entering the interior of the prefabricated cabin body 1 through the air inlet 20. After the protective sleeve 35 is mounted on the air inlet 20, the multiple first magnetic blocks 36 at the bottom thereof and the multiple second magnetic blocks 38 in the groove 37 attract each other, thereby improving the stability of the mounting of the protective sleeve 35.

[0044] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component.
