[0003] In related technologies, during the installation of modular prefabricated composite structures for trusses, when assembling and fixing multiple truss modules, the modules are mostly lifted by a crane and then assembled manually by workers, which greatly increases the workload of the workers and results in low assembly efficiency. Summary of the Invention

[0004] The technical objective of this invention is to provide a modular, automated assembly truss structure and construction method, which aims to reduce the difficulty of truss installation and improve truss assembly efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides a modular automatic assembly truss structure, including at least two hydraulic adaptive leveling devices, truss nodes installed on top of the hydraulic adaptive leveling devices, and truss beams connecting adjacent truss nodes. A first hydraulic rod is slidably disposed within the truss node, and the first hydraulic rod has a first limiting hole penetrating its two circumferentially opposite sides. A fixing groove adapted to the end of the first hydraulic rod is opened at the end of the truss beam. A first electric push rod is fixed to the inner wall of the fixing groove. A fixing rubber sleeve is sleeved on the side wall of the first electric push rod. The shape of the fixing rubber sleeve is adapted to the first limiting hole.

[0008] Furthermore, a high-pressure air pump is provided inside the truss node, and a telescopic airbag is sleeved on the outside of the first hydraulic rod. When the telescopic airbag is in the deflated state, it can extend into the fixed groove along with the first hydraulic rod. A connecting air pipe is connected between the air outlet of the high-pressure air pump and the telescopic airbag.

[0009] Furthermore, an oil storage ring is arranged around the inner wall of the fixed groove near its opening, and multiple oil dripping pipes communicating with its oil storage space are arranged at intervals on the inner wall of the oil storage ring, and each oil dripping pipe is equipped with a solenoid valve.

[0010] Furthermore, a sealing mechanism is provided inside the truss beam. The sealing mechanism includes a water storage tank fixed inside the truss beam, a high-pressure water pump fixed to the inner wall of the water storage tank, a connecting water pipe connected to the high-pressure water pump, and a telescopic water bladder located on the side of the water storage tank near the fixed groove. The telescopic water bladder is connected to the connecting water pipe, and the side wall of the telescopic water bladder is slidably connected to the inner wall of the fixed groove.

[0011] Furthermore, the sealing mechanism also includes a sliding scraper disposed on the side of the telescopic water bladder facing the fixed groove, the sliding scraper extending along the periphery of the telescopic water bladder, and the outer side of the sliding scraper being slidably connected to the inner wall of the fixed groove.

[0012] Furthermore, the sealing mechanism also includes a telescopic rod fixed to the telescopic water bladder facing the fixed groove side, a sealing pad connected to the end of the telescopic rod, and a limiting spring sleeved on the telescopic rod. The limiting spring is in a compressed pre-tightened state, and the minimum length of the telescopic rod is greater than the height of the sliding scraper in its sliding direction.

[0013] Furthermore, a construction method for a modular automated prefabricated truss structure as described in any one of the above claims is provided, comprising:

[0014] Install the hydraulic adaptive leveling device at a preset point and fix the truss node at the top of the hydraulic adaptive leveling device; adjust the height of two adjacent hydraulic adaptive leveling devices so that the truss node heights on them are the same.

[0015] Adjust the position of the truss beam to be located between adjacent truss nodes, and align the fixing groove with the corresponding first hydraulic rod; control the first hydraulic rod to extend into the fixing groove until the first limiting hole is aligned with the first electric actuator; control the first electric actuator to pass through the second limiting hole until the end of the first electric actuator is embedded in the first limiting groove;

[0016] Control all the hydraulic adaptive leveling devices to raise to the predetermined position.

[0021] The process of controlling the first electric actuator to pass through the second limiting hole until the end of the first electric actuator is embedded in the first limiting groove, and then further includes:

[0025] Compared with existing technologies, the modular automated assembly truss structure and construction method of this invention have the following advantages:

[0026] During truss installation, truss nodes can first be installed on top of the hydraulic adaptive leveling device. Adjacent truss nodes are then adjusted to horizontal alignment using this device. Next, the two ends of the truss beam are aligned with the first hydraulic rods of the two adjacent truss nodes. The first hydraulic rods are then driven into the fixing grooves until the position of the first limiting hole aligns with the end of the first electric push rod. The first electric push rod is then driven through the first limiting hole until its end is embedded in the first limiting groove. At this point, the truss beam and truss nodes are stably connected, thus achieving truss assembly. Afterward, by controlling the coordinated lifting and lowering of each hydraulic adaptive leveling device, the truss can be adjusted to the preset position. Therefore, this modular automatic assembly truss structure enables automated assembly, simplifies installation, saves manpower, and significantly improves construction efficiency.

[0036] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] In this embodiment, combined with Figures 1-5A modular, automatically assembled truss structure is provided, comprising at least two hydraulic adaptive leveling devices 1, truss nodes 7 mounted on top of the hydraulic adaptive leveling devices 1, and truss beams 70 connecting adjacent truss nodes 7; a first hydraulic rod 11 is slidably disposed within the truss node 7, the first hydraulic rod 11 having a first limiting hole penetrating its two circumferentially opposite sides; a fixing groove 15 adapted to the end of the first hydraulic rod 11 is opened at the end of the truss beam 70, a first electric push rod 16 is fixed to the inner wall of the fixing groove 15, a fixing sleeve 17 is sleeved on the side wall of the first electric push rod 16, the shape of the fixing sleeve 17 is adapted to the first limiting hole, a first limiting groove 28 is opened on the inner wall of the fixing groove 15 opposite to the first electric push rod 16, when the first electric push rod 16 is fully extended, the end of the first electric push rod 16 and the end of the fixing sleeve 17 are embedded in the first limiting groove 28.

[0040] During truss installation, truss nodes 7 can be first installed on top of the hydraulic adaptive leveling device 1. Adjacent truss nodes 7 are then adjusted to horizontal alignment using the hydraulic adaptive leveling device 1. Next, the two ends of the truss beam 70 are aligned with the first hydraulic rods 11 of the two adjacent truss nodes 7. The first hydraulic rods 11 are driven to extend into the fixing groove 15 until the position of the first limiting hole aligns with the end of the first electric push rod 16. Then, the first electric push rod 16 is driven through the first limiting hole until its end is embedded in the first limiting groove 28. At this point, the truss beam 70 and truss nodes 7 are stably connected, thus achieving truss assembly. The fixing sleeve 17 prevents direct contact between the sidewall of the first electric push rod 16 and the first hydraulic rod 11, protecting both. Afterward, by controlling the coordinated lifting and lowering of each hydraulic adaptive leveling device 1, the truss can be adjusted to the preset position. Therefore, the modular automatic assembly truss structure of this solution can achieve automated assembly, has a simple installation method, saves manpower, and significantly improves construction efficiency.

[0041] It is understandable that the number of hydraulic adaptive leveling devices 1, the number of truss nodes 7, and the number and form of truss beams 70 can be adjusted according to the actual situation. In the example of this application, taking a rectangular truss composed of four hydraulic adaptive leveling devices 1, four truss nodes 7 and four truss beams 70 as an example, the two adjacent faces of the truss nodes 7 are provided with first hydraulic rods 11, and the two ends of the truss beams 70 are respectively provided with fixing grooves 15, first electric push rods 16 and first limiting grooves 28. In some implementations, the number of hydraulic adaptive leveling devices 1, the number of truss nodes 7, and the number of truss beams 70 can be two, three, four, five, etc. The first hydraulic rod 11 can be set on one, two, or three surfaces of the truss node 7, and the shape of the truss node 7 is not limited to a cube shape, but can also be Y-shaped, T-shaped, etc. The shape of the truss beam 70 can be straight, Y-shaped, T-shaped, S-shaped, C-shaped, etc., and the setting positions of the fixing groove 15, the first electric push rod 16, and the first limiting groove 28 are not limited to the end, as long as they can be assembled with the truss node 7.

[0042] Furthermore, combined Figure 2 The hydraulic adaptive leveling device 1 includes a limiting block 2 located at the bottom, a hydraulic telescopic rod 3 fixed to one side of the limiting block 2, a second electric push rod 4 installed on the periphery of the end of the hydraulic telescopic rod 3, and a supporting horizontal plate 5 fixed to the end of the second electric push rod 4. A connecting soft pad 6 is provided on the side of the supporting horizontal plate 5 away from the second electric push rod 4. Specifically, in this embodiment, the limiting block 2 is a rectangular block structure used for positioning and supporting the hydraulic adaptive leveling device 1. For example, if the bottom side of the limiting block 2 is supported on a floor slab or wall, with reference to the view in the attached figure, a second electric push rod 4 is provided on the front, rear, upper, and lower four sides of the end of the hydraulic telescopic rod 3, and a supporting horizontal plate 5 is provided at the end of each electric push rod. A connecting soft pad 6 is fixed on the side of each supporting horizontal plate 5 away from the second electric push rod 4. The connecting soft pad 6 can be made of silicone or rubber materials, etc. When installing the hydraulic adaptive leveling device 1, first adjust the limiting block 2 to the preset position of the building and position it so that the hydraulic telescopic rod 3 is aligned with the wall opening on the building. Control the hydraulic telescopic rod 3 to extend into the wall opening. Then, start the second electric push rod 4 to drive each supporting horizontal plate 5 to expand outward until the connecting soft pad 6 on each supporting horizontal plate 5 presses against the inner wall of the wall opening, thereby realizing the support and fixation of the hydraulic adaptive leveling device 1. This prevents the hydraulic adaptive leveling device 1 from loosening and moving when the equipment is working, ensuring safety and reliability. Moreover, its fixation to the wall opening can be done automatically, which is convenient and quick. The setting of the connecting soft pad 6 can protect the inner wall of the wall opening and make the force more even.

[0043] Furthermore, combined Figure 3The first electric push rod 16 is provided with a second limiting hole that passes through its two circumferentially opposite sides; the inner wall of the fixing groove 15 is provided with a third electric push rod 19 located on one side of the first limiting groove 28. The shape of the third electric push rod 19 is adapted to the second limiting hole. The inner wall of the fixing groove 15 is provided with a second limiting groove 18 located on the other side of the first limiting groove 28. The extension direction of the third electric push rod 19 faces the second limiting groove 18. When the third electric push rod 19 is fully extended, its end is embedded in the second limiting groove 18. After the end of the first electric push rod 16 is embedded in the first limiting groove 28, the third electric push rod 19 is activated, allowing it to pass through the second limiting hole until its end is embedded in the second limiting groove 18. In this way, the third electric push rod 19 can internally limit the first electric push rod 16, further improving the assembly reliability between the truss node 7 and the truss beam 70, resulting in higher reliability.

[0044] Furthermore, in some embodiments, a high-pressure air pump 8 is provided inside the truss node 7, and a telescopic airbag 10 is sleeved on the outside of the first hydraulic rod 11. When the telescopic airbag 10 is in the deflated state, it can extend into the fixed groove 15 along with the first hydraulic rod 11. A connecting air pipe 9 is connected between the air outlet of the high-pressure air pump 8 and the telescopic airbag 10. After the truss node 7 and truss beam 70 are fixedly connected, there is still space in the fixing groove 15 between the truss node 7 and truss beam 70. External dust, moisture, etc. can easily enter the fixing groove 15 through the gap between the truss node 7 and truss beam 70 and corrode the relevant components. In this solution, when the first hydraulic rod 11 enters the fixing groove 15 and is limited by the first electric push rod 16, the high-pressure air pump 8 is started so that gas is input into the telescopic airbag 10 through the connecting air pipe 9. The telescopic airbag 10 expands due to the gas filling and fills the excess space between the first hydraulic rod 11 and the fixing groove 15, thereby achieving a filling seal and preventing rainwater, dust, etc. from entering the fixing groove 15. This makes it safer, more reliable, and has a longer service life.

[0045] Optionally, combined Figure 4 An oil storage ring 12 is arranged around the inner wall of the fixed groove 15 near its opening. Multiple oil dripping pipes 13, connected to the oil storage space, are spaced apart on the inner wall of the oil storage ring 12. Each oil dripping pipe 13 is equipped with a solenoid valve 14. When the first hydraulic rod 11 enters the fixed groove 15, the solenoid valve 14 can be opened. At this time, the maintenance oil in the oil storage ring 12 can flow to the end through the oil dripping pipes 13, thus adhering to the outer wall of the first hydraulic rod 11 as it passes, achieving lubrication and maintenance, preventing the first hydraulic rod 11 from rusting and being damaged, and ensuring the working reliability of the first hydraulic rod 11.

[0046] Furthermore, combined Figures 6-7To ensure the stability of the truss beam 70 when idle, a sealing mechanism is installed inside the truss beam 70. This sealing mechanism includes a water storage tank 20 fixed inside the truss beam 70, a high-pressure water pump 21 fixed to the inner wall of the water storage tank 20, a connecting water pipe 22 connected to the high-pressure water pump 21, and a telescopic water bladder 23 located on the side of the water storage tank 20 near the fixing groove 15. The telescopic water bladder 23 is connected to the connecting water pipe 22, and its side wall is slidably connected to the inner wall of the fixing groove 15. Specifically, the longitudinal section of the side wall of the telescopic water bladder 23 can be a polygonal shape, thus enabling stable expansion and contraction in the axial direction. When the truss beam 70 is idle, the first electric push rod 16 is in the retracted state. At this time, the fixed groove 15 is empty and will not be blocked by the first electric push rod 16. Therefore, the high-pressure water pump 21 can be controlled to pump the water in the water storage tank 20 into the telescopic water bladder 23. After the telescopic water bladder 23 is filled with water, it extends to fill the fixed groove 15, preventing external moisture, dust and other contaminants from entering the fixed groove 15, thus preventing the first electric push rod 16 and the third electric push rod 19 from rusting and ensuring their working reliability.

[0047] Furthermore, the sealing mechanism also includes a sliding scraper 24 disposed on the side of the telescopic water bladder 23 facing the fixed groove 15. The sliding scraper 24 extends along the periphery of the telescopic water bladder 23, and the outer side of the sliding scraper 24 is slidably connected to the inner wall of the fixed groove 15. The sliding scraper 24 is annular and adapts to the inner wall of the fixed groove 15. Therefore, during the extension of the telescopic water bladder 23, if dust or other impurities adhere to the inner wall of the fixed groove 15, the sliding scraper 24 can scrape off the impurities and push them out of the fixed groove 15 through the end of the telescopic water bladder 23, eliminating the need for additional cleaning by personnel and making it more convenient.

[0048] Furthermore, the sealing mechanism also includes a telescopic rod 25 fixed to the telescopic water bladder 23 facing the fixing groove 15, a sealing pad 27 connected to the end of the telescopic rod 25, and a limiting spring 26 sleeved on the telescopic rod 25. The limiting spring 26 is in a compressed pre-tightened state, and the minimum length of the telescopic rod 25 is greater than the height of the sliding scraper 24 in its sliding direction. It should be understood that the telescopic rod 25 can be a sleeve structure, thus enabling telescopic movement over a certain distance. When the first hydraulic rod 11 extends into the fixed groove 15, the sealing pad 27 will be squeezed. At this time, the limit spring 26 is compressed and deformed, and the telescopic rod 25 retracts to its minimum length. Since the length of the telescopic rod 25 after retraction is set to be greater than the height of the sliding scraper 24 in the sliding direction, it can prevent the sealing pad 27 from contacting the sliding scraper 24 and being damaged. When the first hydraulic rod 11 is withdrawn from the fixed groove 15, the limit spring 26 can provide elastic force to make the sealing pad 27 move out of the fixed groove 15. The sealing pad 27 can cover the opening of the fixed groove 15, preventing impurities from entering the fixed groove 15.

[0049] Furthermore, based on the aforementioned modular automated assembly truss structure, combined with Figures 1-7 A construction method is provided, comprising the following steps:

[0050] S1. Install the hydraulic adaptive leveling device 1 at the preset point and fix the truss node 7 at the top of the hydraulic adaptive leveling device 1; adjust the height of the two adjacent hydraulic adaptive leveling devices 1 so that the height of the truss node 7 on them is the same.

[0051] S2. Adjust the position of the truss beam 70 to be located between adjacent truss nodes 7, and align the fixing groove 15 with the corresponding first hydraulic rod 11; control the first hydraulic rod 11 to extend into the fixing groove 15 until the first limiting hole is aligned with the first electric push rod; control the first electric push rod to pass through the second limiting hole until the end of the first electric push rod is embedded in the first limiting groove 28.

[0052] S3. Control all hydraulic adaptive leveling devices 1 to rise to the predetermined position.

[0053] Using the above construction methods, modular automated prefabricated truss structures can be installed conveniently and quickly, saving manpower and resources and increasing efficiency.

[0054] The construction method of this plan will be described in detail below:

[0055] The hydraulic telescopic rod 3 is driven into the positioning hole in the wall, and the second electric push rod 4 is controlled to open the support cross plate 5 and abut against the side wall of the positioning hole. Specifically, when installing the hydraulic adaptive leveling device 1, the limiting block 2 is first adjusted to the preset position of the building and positioned so that the hydraulic telescopic rod 3 is aligned with the wall opening (i.e., the wall positioning hole) on the building. The hydraulic telescopic rod 3 is then controlled to extend into the wall opening. After that, the second electric push rod 4 is activated to drive each support cross plate 5 to expand outward until the connecting pad 6 on each support cross plate 5 abuts against the inner wall of the wall opening, thereby achieving the support and fixation of the hydraulic adaptive leveling device 1. This prevents the hydraulic adaptive leveling device 1 from loosening and moving during operation, ensuring safety and reliability. Moreover, its fixation to the wall opening can be done automatically, which is convenient and quick. The setting of the connecting pad 6 can protect the inner wall of the wall opening and make the force more even. Afterward, the adjacent truss nodes 7 are adjusted to be horizontally aligned by the hydraulic adaptive leveling device 1.

[0056] When installing the truss beam 70, a crane is used to lift the truss beam 70 and adjust it to be positioned between adjacent truss nodes 7, so that the end of the truss beam 70 is aligned with the first hydraulic rod 11 of the corresponding truss node 7. The control solenoid valve 14 is opened, at which time the maintenance oil in the oil reservoir ring 12 can flow to the end through the drip pipe 13, driving the first hydraulic rod 11 to extend into the fixing groove 15 until the first limiting hole is aligned with the first electric push rod 16. The maintenance oil in the drip pipe 13 adheres to the outer wall of the first hydraulic rod 11 as it passes through. The third electric push rod 19 is driven to pass through the second limiting hole until its end is embedded in the second limiting groove 18; the high-pressure air pump 8 is controlled to inflate the telescopic airbag 10, so that the telescopic airbag 10 fills the remaining space of the fixing groove 15. The third electric push rod 19 is activated, allowing it to pass through the second limiting hole until its end is embedded in the second limiting groove 18. In this way, the third electric push rod 19 can internally limit the first electric push rod 16. Understandably, in some implementations, as the first hydraulic rod 11 extends into the fixed groove 15, it squeezes the sealing pad 27, causing the sealing pad 27 and the telescopic water bladder 23 to contract, and the water in the telescopic water bladder 23 flows back into the water storage tank 20.

[0057] Then, control all hydraulic adaptive leveling devices 1 to work together to lift and lower to the predetermined position, completing the assembly of the truss.

[0058] When it is necessary to disassemble the modular automatic assembly truss structure, the process is basically the reverse of the steps of truss installation. The process involves controlling the hydraulic adaptive leveling device 1 to lower it to the predetermined position, then retracting the third electric push rod 19, the first electric push rod 16, the first hydraulic rod 11, and closing the solenoid valve 14 to complete the disassembly of the truss node 7 and the truss beam 70. After that, the second electric push rod 4 and the hydraulic telescopic rod 3 are retracted to complete the disassembly of the hydraulic adaptive leveling device 1. The specific process will not be described in detail here; please refer to the previous installation process. It should be further explained that during the disassembly process, when the first hydraulic rod 11 retracts, the limit spring 26 can provide elastic force to move the sealing pad 27 outward from the fixing groove 15. The sealing pad 27 can cover the opening of the fixing groove 15, preventing impurities from entering the fixing groove 15. The high-pressure water pump 21 can be controlled to pump water from the water tank 20 into the telescopic water bladder 23. After the telescopic water bladder 23 is filled with water, it extends to fill the fixing groove 15, preventing external moisture, dust, etc. from entering the fixing groove 15, thus preventing the first electric push rod 16 and the third electric push rod 19 from rusting. During the extension of the telescopic water bladder 23, if dust or other impurities adhere to the inner wall of the fixing groove 15, the sliding scraper 24 can scrape off the impurities.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
