Description

Technical Field

During construction, workers often need to rely on support devices to stabilize the structure to ensure construction safety and ease of operation. However, existing support devices suffer from drawbacks such as low efficiency, high reliance on manual labor, and insufficient stability. Especially when the target to be supported is located in a narrow space, traditional devices face a dilemma: support devices with large contact areas cannot enter the space, while those that can enter are difficult to provide effective support; for example, when a new building needs to be erected above two adjacent pipes, the support structure needs to pass through the gap between the pipes to support the building.

[0016] Further, preferably, the buffer device includes an elastic buffer element and a push rod assembly, the push rod assembly comprising:

[0017] Multiple push rod platforms are arranged in a circumferential array at one end of the elastic buffer. Each push rod platform has two fixed columns inside, and the fixed columns are rotatably equipped with gears.

[0018] The push rod has tooth grooves on both sides that mesh with the gears. The push rod is slidably disposed between the two gears, and one end of the push rod is provided with an arc-shaped connecting plate.

[0027] Compared with the prior art, the present invention provides a construction auxiliary device with the following beneficial effects:

[0028] This invention overcomes the difficulties of traditional support devices in construction in confined spaces through a pneumatically driven and mechanically linked design, significantly improving the safety, efficiency, and adaptability of the support. Its core advantage lies in its ability to flexibly enter confined spaces: in its retracted state, the extension device can pass through narrow gaps to reach the building requiring support. When the buffer device contacts the building surface, the extension device expands, increasing the support area and improving stability. After support is completed, the extension device automatically retracts and returns to its original position. The leveling device, through the synergistic action of a universal joint and an elastic telescopic rod, allows the support surface to dynamically conform to various irregular building surfaces, improving the device's adaptability to building surfaces. The device is convenient and efficient to operate, automatically completed through pneumatic linkage, requiring no complex manual intervention, thus increasing efficiency.

It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

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

[0041] A two-way hydraulic pump 4 is provided at both ends with telescopic devices 3, the length of which can be changed according to the specific construction conditions;

[0042] The leveling device 2 has one end connected to the telescopic device 3 away from the bidirectional hydraulic pump 4, and the other end is provided with an extension 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 extension device 1, is used to relieve the pressure on the present invention and protect the building surface;

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

[0045] Specifically, such as Figure 2 and Figure 3 The extension device 1 includes:

[0046] A limiting base 13 is disposed at one end of the leveling device 2;

[0047] Multiple extended sliders 11 are arranged circumferentially along the limiting base 13 and slidably disposed on the limiting base 13, and the extended sliders 11 are provided with first limiting pins 110;

[0048] Multiple extrusion sliders 12 are arranged circumferentially along the limiting base 13 and slidably disposed on the limiting base 13, and the extrusion sliders 12 are provided with second limiting pins 120.

[0049] Furthermore, both the expanding slider 11 and the squeezing slider 12 are stepped, and the height and depth of the steps correspond to each other. The expanding slider 11 and the squeezing slider 12 are distributed with gaps between them.

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

[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 to slide and connect the first limiting pin 110; the second limiting groove 132 is used to slide and connect the second limiting pin 120.

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

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

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

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

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

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

[0058] Percentage increase: 700π * 900π ≈ 0.78 = 78%

[0059] Once the support work is completed, the gas is extracted from the telescopic airbag 134, the telescopic airbag 134 contracts, and the compression slider 12 and the expansion slider 11 return to their initial positions.

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

[0061] Multiple push rod platforms 52 are arranged in a circumferential array along one end of the elastic buffer (51). The push rod platform is provided with two fixed columns 54, and the fixed columns 54 are rotatably equipped with gears 55.

[0062] The push rod 56 has tooth grooves on both sides that mesh with the gears 55. The push rod 56 is slidably disposed between the two gears 55, and one end of the push rod 56 is provided with an arc-shaped connecting plate 561.

[0063] Multiple gear sliders 53 are slidably disposed between adjacent push rod platforms 52. Each gear slider 53 has a rack 531 on both sides that meshes with the gear 55. The gear slider 53 serves as the driving source for the push rod 56.

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

[0065] In practical implementation, when not in operation, the elastic buffer 5 is slightly higher than the extension device 1; when supporting the building, the elastic buffer 5 is compressed, and when compressed to its limit position, it is flush with the extension device 1. The compression slider 12 pushes the gear slider 53 to move, and the gear 55 rotates under the drive of the gear slider 53. The push rod 56 pushes the extension slider 11 to expand outward; when the elastic buffer 5 leaves the building surface, the elastic buffer 5 rebounds, the compression slider 12 pulls the gear slider 53 back to its initial position, the push rod 56 retracts, and the extension slider 11 contracts.

[0066] As a preferred option, such as Figure 7 The leveling device 2 includes:

[0067] The base plate 22 is installed on the telescopic device 3. The base plate 22 is provided with a plurality of second connecting keys 28 and a plurality of air injection valves 24 arranged in a circumferential array. The air injection valves 24 penetrate the base plate 22. The outer wall of the base plate 22 is provided with symmetrical bosses 23.

[0068] The top plate 21 has one end fixedly connected to the expansion device 1, and the other end is provided with a first connection key 27 corresponding to the second connection key 28;

[0069] Universal joint 25 is disposed between the base plate 22 and the top plate 21;

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

[0071] In this embodiment, as Figure 8 The telescopic device 3 includes at least a telescopic component and an air supply cylinder 31. The air supply cylinder 31 has a flange 310 corresponding to the boss 23 at one end near the leveling device 2, and an inner wall guide groove. A spring-loaded component 311 is provided between the bottom plate 22 and the air supply cylinder 31.

[0072] In practical implementation, the air injection valve 24 and the air guide hole 131 are connected by the air guide hose 6. A closed air chamber is formed between the leveling device 2 and the telescopic device 3. To ensure the airtightness of the air chamber, a sealing ring is provided between the bottom plate 22 and the inner wall of the air supply cylinder 31. In the non-working state, the boss 23 of the leveling device 2 is in contact with the flange 310 of the telescopic device 3. The leveling device 2 is supported by the rebound member 311 and the gas in the air chamber. When supporting the building, the rebound member 311 is compressed under the building pressure, and the gas in the air chamber is forced out. It flows through the air injection valve 24, 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 support work is completed, the rebound member 311 rebounds, the air chamber space is restored, the gas in the telescopic airbag 134 is extracted, the telescopic airbag 134 contracts, and the expansion device 1 contracts.
