[0040] Please refer to Figures 1-8 In an embodiment of the present invention, a building auxiliary construction device is provided, comprising:

[0041] A bidirectional hydraulic pump 4, with telescopic devices 3 provided at both ends. The length of the telescopic devices 3 can be changed according to the specific construction conditions.

[0042] A leveling device 2, one end of which is connected to the end of the telescopic device 3 away from the bidirectional hydraulic pump 4, and the other end is provided with an expansion device 1. The leveling device 2 can adapt to the inclination of the building surface so that the support surface of the device always fits the building;

[0043] A buffer device 5, which is installed on the expansion device 1, is used to relieve the pressure on the present invention and protect the surface of the building;

[0044] The telescopic device 3 is driven by the bidirectional hydraulic pump 4 .

[0045] Specifically, if Figure 2 and Figure 3 , the expansion device 1 includes:

[0046] a limiting base 13, which is provided at one end of the leveling device 2;

[0047] A plurality of extension sliders 11 arranged in a circumferential direction along the limiting base 13 and slidably disposed on the limiting base 13, wherein the extension sliders 11 are provided with a first limiting pin 110;

[0048] A plurality of extrusion sliders 12 are arranged in an array along the circumference of the limiting base 13 and are slidably disposed on the limiting base 13 . The extrusion sliders 12 are provided with second limiting pins 120 .

[0049] Furthermore, the expansion slider 11 and the extrusion slider 12 are both stepped, and the heights and depths of the steps correspond to each other. The expansion slider 11 and the extrusion slider 12 are distributed with a gap.

[0050] In this embodiment, Figure 2 and Figure 3 , the end of the limiting base 13 away from the angle adjustment end is provided with a slide rail 133 corresponding to the extrusion slider 12;

[0051] The limiting base 13 is provided with a first limiting groove 130 and a second limiting groove 132 . The first limiting groove 130 is used for slidingly connecting the first limiting pin 110 ; the second limiting groove 132 is used for slidingly connecting the second limiting pin 120 .

[0052] The slide rail 133, the first limiting groove 130, and the second limiting groove 132 all play a role in positioning and guiding. It should be noted that the length of the first limiting groove 130 determines the extension range of the extension slider 11, and the length of the second limiting groove 132 determines the extrusion range of the extrusion slider 12.

[0053] Preferably, an air guide hole 131 communicating with the second limiting groove 132 is provided on the outer wall of the limiting base 13, and a telescopic airbag 134 is provided between the air guide hole 131 and the second limiting pin 120, so that the state of the telescopic airbag 134 can be controlled by controlling the gas entering the telescopic airbag 134.

[0054] In a specific implementation, when not in operation, no gas enters the telescopic airbag 134, the telescopic airbag 134 is in a contracted state, and the extrusion slider 12 and the expansion slider 11 are in their initial positions. When supporting a building, gas enters the telescopic airbag 134 from the air guide hole 131, and the telescopic airbag 134 expands and stretches, pushing the extrusion slider 12 to slide along the slide rail 133, and the air on the other side is discharged from the exhaust hole. During this process, the expansion slider 11 expands outward and stops after reaching the limit position, and the support area is expanded by 60% to 80%. For example, in the initial state, the support coverage area of multiple expansion sliders 11 is a circle with a radius of 20CM, and the length of the first limiting groove 130 is 10CM.

[0055] Initial support area: π×30 2 =900π

[0056] Extended support area: π×40 2 =1600π

[0057] Area difference: 1600π - 900π = 700π

[0058] Expansion percentage: 700π*900π≈0.78=78%

[0059] When the supporting work is completed, the gas is extracted from the telescopic airbag 134, the telescopic airbag 134 contracts, and the squeezing slider 12 and the expanding slider 11 return to their initial positions.

[0060] In this embodiment, Figure 4 and Figure 5 The buffer device 5 includes an elastic buffer member 51 and a push rod assembly, and the push rod assembly includes:

[0061] A plurality of push rod platforms 52 are arranged in an array along the circumference of the elastic buffer 51 at one end of the elastic buffer (51), two fixed columns 54 are provided inside the push rod platform, and the fixed columns 54 are rotatably provided with gears 55;

[0063] A plurality of gear sliders 53 are provided, each gear slider 53 being slidably disposed between adjacent push rod platforms 52 . Racks 531 meshing with the gears 55 are provided on both sides of the gear slider 53 . The gear slider 53 serves as a driving source for the push rod 56 .

[0064] As a preference, Figure 6The push rod platform 52 corresponds to the extension slider 11, and the arc-shaped connecting plate 561 is fixedly connected to the stepped inner wall of the extension slider 11. The arc-shaped connecting plate 561 increases the contact area between the push rod 56 and the extension slider 11, thereby improving the sliding stability of the extension slider 11. The gear slider 53 corresponds to the extrusion slider 12, and one end of the gear slider 53 is fixedly connected to the stepped inner wall of the extrusion slider 12.

[0065] During specific implementation, in a non-working state, the elastic buffer 5 is slightly higher than the expansion device 1; when supporting a building, the elastic buffer 5 is compressed, and when compressed to the extreme position, it is flush with the expansion device 1, and the extrusion slider 12 pushes the gear slider 53 to move, and the gear 55 rotates under the drive of the gear slider 53, and the push rod 56 pushes the expansion slider 11 to expand outward; when the elastic buffer 5 leaves the surface of the building, the elastic buffer 5 rebounds, the extrusion slider 12 pulls the gear slider 53 back to its initial position, the push rod 56 retracts, and the expansion slider 11 contracts.

[0069] A universal joint 25 , which is provided between the bottom plate 22 and the top plate 21 ;

[0070] At least three elastic telescopic rods 26 are hinged between corresponding first connecting keys 27 and second connecting keys 28 .

[0071] In this embodiment, Figure 8 The telescopic device 3 includes at least a telescopic assembly and an air supply cylinder 31. The air supply cylinder 31 is provided with a flange 310 corresponding to the boss 23 at one end close to the leveling device 2, and a guide groove on the inner wall. A rebound member 311 is provided between the base plate 22 and the air supply cylinder 31.

[0072] During specific implementation, an air guide hose 6 is used to connect the air injection valve 24 and the air guide hole 131, and a closed air chamber is formed between the leveling device 2 and the telescopic device 3. To ensure the air tightness of the air chamber, a sealing ring is provided between the base plate 22 and the inner wall of the air supply cylinder 31; when in a non-working state, the boss 23 of the leveling device 2 fits with the flange 310 of the telescopic device 3, and the leveling device 2 is supported by the rebound member 311 and the gas in the air chamber; when supporting a building, the rebound member 311 is compressed under the building pressure, and the gas in the air chamber is pressed out, flows through the air injection valve 24, passes through the air guide hose 7 and the air guide hole 131, and is introduced into the telescopic airbag 134, causing the telescopic airbag 134 to expand and extend, driving the expansion device 1 to expand; when the supporting work is completed, the rebound member 311 rebounds, the air chamber space is restored, the gas in the telescopic airbag 134 is extracted, and the telescopic airbag 134 contracts, driving the expansion device 1 to contract.
