Description

Technical Field

[0001] This utility model relates to the field of equipment housing technology, and in particular to a support structure for prefabricated assembled houses. Background Technology

[0002] Prefabricated buildings refer to the transfer of a large amount of on-site work in traditional construction methods to factories. Building components and accessories, such as floor slabs, wall panels, stairs, and balconies, are prefabricated in factories and then transported directly to the construction site for assembly and installation using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they represent modern industrialized production methods.

[0003] In the prior art, hydraulic support structures are needed to assist in the assembly of prefabricated houses. However, due to device failure, the hydraulic support force may be insufficient, leading to the risk of sudden retraction of the telescopic rod, which reduces the stability of the support structure. In severe cases, it may cause the top assembly structure to collapse, affecting the personal safety of workers. Therefore, in order to solve the above problems, this utility model proposes a support structure for prefabricated assembled houses. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a prefabricated assembled house support structure. By using an electric actuator to drive the limiting claw to rotate, the engagement between the limiting claw and the racks on both sides of the telescopic rod is adjusted to lock the telescopic rod, preventing it from loosening, improving the stability of the support structure, reducing the risk of collapse due to insufficient hydraulic support, and ensuring the personal safety of workers.

[0005] This utility model provides the following technical solution: a prefabricated assembled house support structure, including a hydraulic rod, with a telescopic rod movably sleeved at the upper end of the hydraulic rod. The telescopic rod has grooves on its left and right sides, and racks are fixedly installed in the grooves. Fixing frames are fixedly installed on the upper end of the hydraulic rod and on both sides of the telescopic rod. Limiting claws are movably connected to the fixing frames via shafts. The end of the limiting claw near the telescopic rod engages with the rack. Electric actuators are movably connected to the left and right sides of the hydraulic rod via shafts. The telescopic end of the electric actuator is movably connected to the end of the limiting claw away from the telescopic rod via a shaft. The electric actuator drives the limiting claw to rotate, adjusting the engagement between the limiting claw and the racks on both sides of the telescopic rod, thus fixing the telescopic rod, preventing loosening, improving the stability of the device, reducing the risk of collapse due to insufficient hydraulic support, and ensuring the personal safety of workers.

[0006] Preferably, the hydraulic rod is movably connected to support rods via shafts. There are three support rods located below the electric actuator. The end of each support rod away from the hydraulic rod is movably connected to a support plate via a shaft. By setting three sets of support rods, the contact area between the device and the ground is increased, the friction between the device and the ground is increased, and the three support rods provide good support for the hydraulic rod, preventing the bottom of the hydraulic rod from sliding during operation.

[0007] Preferably, a suction cup is fixedly installed at the bottom of the support plate, an air pump is fixedly installed on the suction cup, and a buffer seat is fixedly installed at the top of the telescopic rod. The air pump creates a negative pressure environment between the inner cavity of the suction cup and the ground. The pressure difference is used to fix the end of the support rod away from the hydraulic rod to the ground. Compared with fixing with bolts, this avoids damage to the ground and floor of the prefabricated house and prevents compromise to the overall safety of the prefabricated house.

[0008] Preferably, four damping rods are uniformly fixedly installed at the bottom of the inner cavity of the buffer seat. A buffer block is movably sleeved on the upper part of the inner cavity of the buffer seat. The bottom of the buffer block is fixedly connected to the telescopic end of the damping rod. A support plate is fixedly installed on the upper part of the buffer block. When the device is supporting, the support plate drives the buffer block into the inner cavity of the buffer seat, so that the damping rod is compressed to generate elastic potential energy to provide buffering and avoid vibration from interfering with the stability of the device support.

[0009] Compared with the prior art, the advantages of this utility model are as follows:

[0010] 1. The limit pawl is rotated by the electric actuator, so that the limit pawl and the racks set on the left and right sides of the telescopic rod are engaged, thereby fixing the telescopic rod's extension length. This prevents the telescopic rod from loosening due to malfunctions during the use of the device, which helps to improve the stability when the hydraulic rod and the telescopic rod are supporting each other, reduces the risk of the upper assembly floor collapsing due to insufficient hydraulic support, and ensures the personal safety of the workers during assembly operations.

[0011] 2. After the hydraulic rod is erected on the ground, the suction cup is brought into contact with the ground by rotating the support rod. The air pump creates a negative pressure environment between the inner cavity of the suction cup and the ground. The pressure difference fixes the end of the support rod away from the hydraulic rod to the ground, which improves the firmness of the connection between the support structure and the ground. Compared with fixing by drilling holes with screws, this method can effectively avoid damage to the ground and floor of the prefabricated house and prevent damage to the prefabricated structure from affecting the overall safety of the house.

[0012] 3. When the hydraulic rod drives the telescopic rod to rise for support, the support plate at the top of the telescopic rod first contacts the prefabricated house structure to be supported above. After being subjected to pressure, the support plate moves downward, driving the buffer block into the inner cavity of the buffer seat. This causes the damping rod to compress and generate elastic potential energy to provide buffering, effectively reducing the adverse effects of vibration on the stability of the top support of the device during operation, and at the same time avoiding excessive support force applied by the support device to the prefabricated structure, which could cause structural damage.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4A prefabricated modular housing support structure includes a hydraulic rod 1, with a telescopic rod 2 movably sleeved at the upper end of the hydraulic rod 1. The telescopic rod 2 has grooves 3 on its left and right sides, with racks 4 fixedly installed in the grooves 3. Fixing frames 5 are fixedly installed on the upper end of the hydraulic rod 1 and on the left and right sides of the telescopic rod 2, respectively. Limiting claws 6 are movably connected to the fixing frames 5 via shafts. The end of the limiting claw 6 near the telescopic rod 2 engages with the rack 4. Electric actuators 7 are movably connected to the left and right sides of the hydraulic rod 1 via shafts. The telescopic end of the electric actuator 7 is movably connected to the end of the limiting claw 6 away from the telescopic rod 2 via a shaft. When the telescopic rod 2 rises to a suitable position, the electric actuator 7 is activated. The extension end of the electric actuator 7 extends and drives the limiting claw 6 to rotate toward the telescopic rod 2 on the fixed frame 5, so that the limiting claw 6 and the racks 4 set on the left and right sides of the telescopic rod 2 are engaged, thereby fixing the telescopic length of the telescopic rod 2. This prevents the telescopic rod 2 from loosening due to malfunction during the use of the device, which helps to improve the stability when the hydraulic rod 1 and the telescopic rod 2 are supported, reduces the risk of the upper assembly floor slab collapsing due to insufficient hydraulic support, and ensures the personal safety of the workers when performing assembly operations. When the telescopic rod 2 needs to adjust its telescopic length, the limiting claw 6 can be rotated by the electric actuator 7 to disengage from the racks 4.

[0020] Three support rods 8 are evenly connected to the hydraulic rod 1 via shafts and are located below the electric actuator 7. The end of the support rod 8 away from the hydraulic rod 1 is movably connected to the support plate 9 via shafts. A suction cup 10 is fixedly installed at the bottom of the support plate 9, and an air pump 11 is fixedly installed on the suction cup 10. A buffer seat 12 is fixedly installed at the top of the telescopic rod 2. First, the hydraulic rod 1 is erected on the ground. The support rod 8 is rotated so that the suction cup 10 at the bottom of the support plate 9 contacts the ground. By starting the air pump 11, a negative pressure environment is formed between the inner cavity of the suction cup 10 and the ground. The air pressure is used to fix the end of the support rod 8 away from the hydraulic rod 1 to the ground, so that the three support rods 8 provide good support for the hydraulic rod 1. By setting three sets of suction cups 10, the grounding area of ​​the device is increased, the friction between the device and the ground is improved, and the firmness of the connection between the support structure and the ground is enhanced. Compared with fixing by drilling holes with screws, this method can effectively avoid damage to the ground and floor of the prefabricated house and prevent damage to the prefabricated structure from affecting the overall safety of the house.

[0021] Damping rods 13 are evenly fixedly installed at the bottom of the inner cavity of the buffer seat 12. There are four damping rods 13. A buffer block 14 is movably sleeved on the upper part of the inner cavity of the buffer seat 12. The bottom of the buffer block 14 is fixedly connected to the telescopic end of the damping rod 13. A support plate 15 is fixedly installed on the upper part of the buffer block 14. When the hydraulic rod 1 is activated, the telescopic rod 2 extends upward through hydraulic pressure. The support plate 15 at the top of the telescopic rod 2 contacts the prefabricated house structure that needs to be supported above. After being subjected to pressure, the support plate 15 moves downward, driving the buffer block 14 into the inner cavity of the buffer seat 12. This causes the damping rod 13 to compress and generate elastic potential energy to provide buffering, effectively reducing the adverse effects of vibration on the stability of the top support of the device during operation. At the same time, it avoids excessive support force applied by the support device to the prefabricated structure, which could cause structural damage.

[0022] Working principle: First, erect the hydraulic rod 1 on the ground. Rotate the support rod 8 so that the suction cup 10 at the bottom of the support plate 9 contacts the ground. Start the air pump 11 to create a negative pressure environment between the inner cavity of the suction cup 10 and the ground. Use air pressure to fix the end of the support rod 8 away from the hydraulic rod 1 to the ground, so that the three support rods 8 provide good support for the hydraulic rod 1. Start the hydraulic rod 1 to extend the telescopic rod 2 upward through hydraulic pressure. The support plate 15 at the top of the telescopic rod 2 contacts the prefabricated house structure that needs to be supported above. After being pressed, the support plate 15 moves downward. The movement causes the buffer block 14 to enter the inner cavity of the buffer seat 12, which compresses the damping rod 13 to generate elastic potential energy to provide buffering. When the telescopic rod 2 rises to the appropriate position, the electric actuator 7 is activated. The extension end of the electric actuator 7 extends and drives the limiting claw 6 to rotate on the fixed frame 5 toward the telescopic rod 2, so that the limiting claw 6 and the racks 4 set on the left and right sides of the telescopic rod 2 are engaged, thereby fixing the telescopic length of the telescopic rod 2. When the telescopic length of the telescopic rod 2 needs to be adjusted, the limiting claw 6 is rotated by the electric actuator 7 to disengage from the rack 4.
