DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] Example 1: Reference Figure 1-Figure 11 A seismic-resistant steel structure prefabricated building comprises: a base plate 1, a bearing column 2, a slide groove 3, a lifting mechanism 4 and an auxiliary bearing column 5. Four slide grooves 3 are opened on the base plate 1, and the end of each slide groove 3 is connected to the end of a bearing column 2. Two adjacent slide grooves 3 are vertically arranged, and the other end of the slide groove 3 is far away from the lifting mechanism 4 in the middle of the base plate 1. The output end of the lifting mechanism 4 is connected to the auxiliary bearing column 5, and the bottom of the auxiliary bearing column 5 is slidably connected to the slide groove 3. The bearing column 2 and the auxiliary bearing column 5 are connected to the base plate 1 through a shock absorbing mechanism, and the shock absorbing mechanism is connected to the lifting mechanism 4.

[0032] The principles and beneficial effects of the above scheme are:

[0033] The bearing column 2 on the base plate 1 can support the building. When the building pressure supported by the device is large, the bending moment applied to the device increases. At this time, the lifting mechanism 4 is started. Under the guidance of the slide groove 3 and the cooperation of the shock-absorbing mechanism, the lifting mechanism 4 drives the auxiliary bearing column 5 to move toward the bearing column 2. At the same time, the length of the auxiliary bearing column 5 increases to the same as the height of the bearing column 2. The shock-absorbing mechanism works synchronously and provides support for the bearing column 2 and the auxiliary bearing column 5, and at the same time, the vibration on the bearing column 2 and the auxiliary bearing column 5 is buffered. By setting the lifting mechanism 4, the auxiliary bearing column 5 can be moved close to the bearing column 2 to increase the cross-sectional area of ​​a single bearing column 2 during support. At the same time, the height of the auxiliary bearing column 5 is adjusted to be equal to the height of the bearing column 2, thereby increasing the ability of the device to resist greater bending moments, greatly increasing the safety of the device; the shock-absorbing mechanism can buffer the vibrations received by the bearing column 2 and the auxiliary bearing column 5, and at the same time, the bearing column 2 and the auxiliary bearing column 5 can be auxiliary supported, further improving the safety of the device.

[0034] Example 2: Reference Figure 1-Figure 11 A pressure plate 6 is installed on the top of the bearing column 2.

[0035] The principles and beneficial effects of the above scheme are:

[0036] The provision of the pressure-bearing plate 6 increases the contact area between the bearing column 2 and the building, reduces the pressure exerted by the device on the building, and prevents the device from causing damage to the building when implementing support.

[0037] Example 3: Reference Figure 1-Figure 11 The lifting mechanism 4 includes: a motor 7, a screw 8, a cross lifting frame 9 and a second slide 10. The motor 7 is connected to the middle of the bottom plate 1, and the output shaft of the motor 7 is connected to the screw 8. The screw 8 is threadedly connected to the cross lifting frame 9. A second slide 10 is opened through the top of each side of the cross lifting frame 9. Each second slide 10 is concentrically arranged with a slide 3. One end of the second slide 10 is longitudinally slidably connected to the bearing column 2, and the second slide 10 is slidably connected to the auxiliary bearing column 5.

[0038] The principles and beneficial effects of the above scheme are:

[0039] The motor 7 is started, and the output end of the motor 7 rotates forward to drive the screw 8 to rotate forward. Under the cooperation of the bearing column 2 and the second slide groove 10, the cross lifting frame 9 moves upward, and at the same time, the second slide groove 10 of the cross lifting frame 9 is slidably connected with the auxiliary bearing column 5;

[0040] The motor 7 is started again, and the output end of the motor 7 is reversed to drive the screw 8 to reverse. With the cooperation of the bearing column 2 and the second slide groove 10, the cross lifting frame 9 moves downward. At the same time, the second slide groove 10 of the cross lifting frame 9 is slidably connected with the auxiliary bearing column 5. The screw 8 is threadedly connected with the cross lifting frame 9 in the mechanism. The second slide groove 10 of the cross lifting frame 9 is slidably connected with the bearing column 2 and the auxiliary bearing column 5, which is convenient for efficiently driving the cross lifting frame 9 to move upward or downward relative to the base plate 1; at the same time, the cross lifting frame 9 moving upward or downward is convenient for supporting the bearing column 2 according to actual conditions and dispersing the force on it.

[0041] Example 4: Reference Figure 1-Figure 11 The auxiliary bearing column 5 includes: a column 14, the second slide groove 10 is slidably connected to the column 14, the bottom of the column 14 is slidably connected to the slide groove 3, the top of the column 14 is slidably connected to the second column 12, and the bottom of the second column 12 is in contact with the top of the cross lifting frame 9.

[0042] The principles and beneficial effects of the above scheme are:

[0043] When the cross lifting frame 9 moves upward, the column 14 is connected to the second slide slot 10 in a longitudinal sliding manner, and the rising cross lifting frame 9 drives the second column 12 to slide upward relative to the column 14 until the top of the second column 12 is at the same height as the top of the bearing column 2, so as to support the building together;

[0044] When the cross lifting frame 9 moves downward, the column 14 is connected to the second slide groove 10 in a longitudinal sliding manner, and the descending cross lifting frame 9 drives the second column 12 to slide downward relative to the column 14 until the height of the top of the second column 12 reaches its initial position, so as to end the support of the building;

[0045] At the same time, when the device is subjected to a large bending moment, the cross lifting frame 9 can be raised to apply lateral support to the bearing column 2 and the column 14, thereby further reducing the impact on the device under the large bending moment.

[0046] Example 5: Reference Figure 1-Figure 11 A second pressure plate is installed on the top of the second column 12.

[0047] The principles and beneficial effects of the above scheme are:

[0048] A pressure plate 2 is installed on the top of the second column 12 to further increase the contact area between the device and the building, reduce the pressure exerted by the device on the building, and further provide protection for the building.

[0049] Example 6: Reference Figure 1-Figure 11 The bottom of the second support plate is connected to the top of the spring 13 , and the bottom of the spring 13 is connected to the positioning plate 11 in the column 14 .

[0050] The principles and beneficial effects of the above scheme are:

[0051] When the second column 12 slides upward relative to the column 14, the spring 13 is stretched under the fixation of the positioning plate 11, which can limit the second column 12 to prevent it from falling off the column 14;

[0052] When column 2 12 slides downward relative to column 14, under the fixation of positioning plate 11, spring 13 is reset synchronously, and auxiliary power is applied to column 2 12 to reset, so as to prevent column 2 12 from getting stuck on column 14, thereby reducing the complexity of the preparation work before the device supports the building again.

[0053] Example 7: Reference Figure 1-Figure 11 The screw rod 8 is threadedly connected with a screw block 15 , and the screw block 15 is connected with four sliders 16 , and each slider 16 is slidably connected with a bearing column 2 .

[0054] The principles and beneficial effects of the above scheme are:

[0055] When the screw rod 8 rotates forward, the screw block 15 moves upward with the cooperation of the slider 16 on the bearing column 2; when the screw rod 8 rotates reversely, the screw block 15 moves downward with the cooperation of the slider 16 on the bearing column 2, which greatly improves the consistency and accuracy of the synchronous upward or downward movement of multiple sliders 16; at the same time, the connection between the screw block 15 and the slider 16 cooperates with the cross lifting frame 9 with adjusted height, further dispersing the pressure on the bearing column 2, increasing the safety of the device when in use, and at the same time allowing the side of the bearing column 2 to be more reasonably supported to prevent it from deforming after long-term pressure.

[0056] Example 8: Reference Figure 1-Figure 11 The shock absorbing mechanism includes: a slider 2 17, each of the sliders 16 is connected to a slider 2 17 on both sides, the slider 2 17 is slidably connected to the slide groove 3 18, the slide groove 3 18 is provided on the support plate 20, the bottom wall of the slide groove 3 18 is connected to the slider 2 17 through the spring 2 19, the slide groove 4 21 on the support plate 20 is slidably connected to the slider 3 22, the slider 3 22 is installed on the side of the column 14, the slider 3 22 is arranged below the slider 2 17, and the slider 3 22 is connected to the bottom wall of the slide groove 4 21 through the spring 3 23.

[0057] The principles and beneficial effects of the above scheme are:

[0058] When the slider 16 moves upward, the slider 2 17 moves upward synchronously and drives the top of the support plate 20 to move upward, the spring 2 19 is compressed, the spring 3 23 is compressed synchronously, and the support plate 20 rotates in the opposite direction around the slider 3 22, and with the cooperation of the slide groove 3 and the slide groove 2 10, the column 14 moves toward the load-bearing column 2, thereby increasing the supporting cross-sectional area of ​​the load-bearing column 2 when the device is supported; when the slider 16 moves downward, the slider 2 17 moves downward synchronously and drives the top of the support plate 20 to move downward, the spring 2 19 resets and extends, the spring 3 23 resets and extends synchronously, and the support plate 20 rotates forward around the slider 3 22, and with the cooperation of the slide groove 3 and the slide groove 2 10, the column 14 moves in the direction away from the load-bearing column 2. A power device can be used in the device to drive the column 14 close to or away from the load-bearing column 2, and at the same time, the column 2 12 can be moved upward or downward, which greatly reduces the complexity of the device, reduces the setting of the power device, and reduces the complexity and cost of the device production.

[0059] Example 9: Reference Figure 1-Figure 11 A slider 4 24 is connected to the middle of each support plate 20, and the slider 4 24 is slidably connected to the slide groove 5 26. The slide groove 5 26 is opened on the support plate 29, and the bottom wall of the slide groove 5 26 is connected to the slider 4 24 through a spring 4 25. The bottom of the support plate 29 is connected to the locking mechanism 27, and the bottom of the support plate 20 is connected to the locking mechanism 28. The locking mechanism 27 and the locking mechanism 28 are both slidably connected to the bottom plate 1.

[0060] The principles and beneficial effects of the above scheme are:

[0061] Under the cooperation of the locking mechanism 27 and the bottom plate 1 in sliding connection, when the top of the support plate 20 moves upward, the slider 4 24 is driven to move, and the slider 4 24 drives the spring 4 25 and the support plate 2 29 to move upward, and the spring 4 25 is compressed;

[0062] When the top of the support plate 20 moves downward, the slider 24 is driven to move, and the slider 24 drives the spring 25 and the support plate 29 to move downward, and the spring 25 is reset;

[0063] When the support plate 20 and the second support plate 29 move upward or downward, the locking mechanism 28 and the locking mechanism 27 provide guidance for their movement and slide relative to the bottom plate 1. When the locking mechanism 28 and the locking mechanism 27 move into place, they lock the support plate 20 and the second support plate 29 respectively. Subsequently, when the column 14 and the bearing column 2 are vibrated, the slider 2 17 and the slider 3 22 can apply pressure to the spring 2 19 and the spring 3 23 respectively, thereby buffering the vibration. At the same time, the slider 4 24 can also apply pressure to the spring 4 25, thereby buffering the vibration. The setting of the locking mechanism 27 and the locking mechanism 2 28 increases the supporting effect of the support plate 20 and the second support plate 29 on the column 14 and the bearing column 2. At the same time, the spring 2 19, the spring 3 23 and the spring 4 25 absorb and buffer the vibration of the device. The two adjacent sides of the lifting frame 9 can support the two adjacent columns 14 and the two adjacent bearing columns 2, which greatly increases the stability of the device when in use; further, since the heights of the support plate 20 and the support plate 29 can be adjusted with the spacing between the column 14 and the bearing column 2, and the support plate 20 and the support plate 29 are respectively locked on the base plate 1 by the locking mechanism 28 and the locking mechanism 27, when the angle between the support plate 20 and the support plate 29 is reduced, that is, the spacing between the column 14 and the bearing column 2 is reduced, the bearing capacity of the device and the ability to resist greater bending moments are increased, the spring 2 19, the spring 3 23 and the spring 4 25 are each compressed to assist in increasing the device's ability to withstand vibrations during the earthquake resistance process, thereby improving the device's ability to automatically adjust and its adaptability to a variety of different working conditions.

[0064] Example 10: Reference Figure 1-Figure 11 The base plate 1 is connected to a pump casing 30, which is rotationally sealed with the output shaft of the motor 7. A rotating cylinder 31 is rotationally sealed inside the pump casing 30, which is connected with the output shaft of the motor 7. A plurality of storage holes 32 are opened on the side wall of the rotating cylinder 31, and the storage holes 32 are filled with hydraulic oil. A plurality of pipes 33 and the end of pipe 2 are connected to the pump casing 30, and the other end of pipe 33 is connected to the locking mechanism 27, and the other end of pipe 2 is connected to the locking mechanism 28.

[0065] The principles and beneficial effects of the above scheme are:

[0066] After the motor 7 is started, its output shaft rotates, driving the rotating cylinder 31 to rotate, and the hydraulic oil stored in the storage hole 32 of the rotating cylinder 31 is respectively input to the locking mechanism 27 and the locking mechanism 28 through the pipeline 33 and the pipeline 2 on the pump housing 30, and the two are respectively unlocked, and the device can further drive the support plate 20 and the support plate 29 to move; when the movement of the support plate 20 and the support plate 29 is completed, the motor 7 is turned off, and the rotation of its output shaft stops, and the hydraulic oil in the pipeline 33 and the pipeline 2 flows back to the storage hole 32 again, and the locking mechanism 27 and the locking mechanism 28 are locked at the same time;

[0067] The device uses centrifugal action to output the hydraulic oil through the rotating storage hole 32, and at the same time drives the locking mechanism 27 and the locking mechanism 2 28 to be unlocked in real time by taking advantage of the low compressibility of the hydraulic oil. Moreover, no matter what the rotation direction of the output shaft of the motor 7 is, the hydraulic oil can be output in time, that is, the locking mechanism 27 and the locking mechanism 2 28 can be unlocked synchronously when the support plate 20 and the support plate 2 29 need to move, and no mechanical interference will occur.

[0068] Example 11: Reference Figure 1-Figure 11 , one end of the slide slot 3 is spaced apart from the end of the sixth slide slot 34, and the other end of the slide slot 3 is spaced apart from the end of the seventh slide slot 35. The sixth slide slot 34 and the seventh slide slot 35 are both provided on the bottom plate 1. A movable column 36 of a locking mechanism 27 is slidably connected in the sixth slide slot 34. The top of the movable column 36 is hinged to the bottom of the second support plate 29. A gear 37 is connected to the movable column 36. The gear 37 is meshed with a rack 38. The rack 38 is connected to the bottom plate 1 through a push spring 39. The rack 38 is slidably connected to the bottom plate 1. A pipe 33 is connected to the bottom plate 1. A retaining ring 40 is connected to the other end of the pipe 33. The bottom of the retaining ring 40 is connected to the top of the disc through a return spring 41. The disc and the pipe 33 are slidably sealed. The push rod 42 at the top of the disc is slidably sealed with the inner wall of the retaining ring 40. The top of the push rod 42 is in contact with the chamfer at the bottom of the rack 38, and the chamfer is arranged toward the movable column 36;

[0069] A moving column 243 of a locking mechanism 28 is slidably connected in the slide groove 7 35 , the top of the moving column 243 is hinged to the bottom of the support plate 20 , a gear 244 is connected to the moving column 243 , the gear 244 is meshed with a rack 245 , the rack 245 is connected to the bottom plate 1 through a push spring 2 , the rack 245 is slidably connected to the bottom plate 1 , a pipe 2 is connected to the bottom plate 1 , a retaining ring 2 is connected to the other end of the pipe 2 , the bottom of the retaining ring 2 is connected to the top of the disc 2 through a reset spring 2 , the disc 2 is slidably sealed with the pipe 2 , the push rod 2 at the top of the disc 2 is slidably sealed with the inner wall of the retaining ring 2 , the top of the push rod 2 is in contact with the chamfer 2 at the bottom of the rack 245 , and the chamfer is arranged toward the moving column 243 ;

[0070] The rack 38 and the rack 2 45 are arranged diagonally;

[0071] The central axes of the adjacent chute 3, chute 6 34 and chute 7 35 are arranged collinearly.

[0072] The principles and beneficial effects of the above scheme are:

[0073] After the output shaft of the motor 7 rotates, the hydraulic oil enters the pipe 33 and the pipe 2 respectively, so the pressure of the hydraulic oil in the pipe 33 and the pipe 2 increases, thereby increasing the pressure on the disc and the disc 2, and then respectively moving the push rod 42 and the push rod 2 upward, while the return spring 41 contracts under the restriction of the retaining ring 40, and the return spring 2 contracts under the restriction of the retaining ring 2, the rising push rod 42 applies pressure to the chamfer at the bottom of the rack 38, the rack 38 slidably connected to the bottom plate 1 moves away from the gear 37, the push spring 39 contracts under pressure, the rising push rod 2 applies pressure to the chamfer 2 at the bottom of the rack 2 45, the rack 2 45 slidably connected to the bottom plate 1 moves away from the gear 2 44, the push spring 2 contracts under pressure, and at this time the moving column 36 is unlocked and slides in the chute 6 34, and the moving column 2 43 is unlocked and slides in the chute 7 35;

[0074] When the bearing column 2 and the column 14 are moved into position, the rotation of the output shaft of the motor 7 ends, the pressure of the hydraulic oil in the pipe 33 and the second pipe is reduced, the reset spring 41 and the push spring 39 are reset, the rack 38 is meshed and connected with the gear 37 again, the reset spring 2 and the push spring 2 are reset, and the rack 2 45 is meshed and connected with the second gear 44 again;

[0075] The mechanism is provided with a rack 38 meshing with the gear 37, and a rack 2 45 meshing with the gear 2 44, which greatly utilizes the existing parts for manufacturing the device, reducing the production cost. At the same time, the unlocking and locking principle in the mechanism is simple and easy to implement, and has strong practicality.

[0076] The rack 38 and the second rack 45 are arranged diagonally, so the support plate 20 and the second support plate 29 are limited when they swing left and right relative to the slide groove 3, and the supporting column 2 and the column body 14 are further limited left and right, which greatly reduces the number of parts used in the manufacture of the device.

[0077] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
