Description

A combined truss connection device with angle adjustment function Technical Field

[0001] This invention relates to the field of double-chord beam technology, specifically a combined truss connection device with angle adjustment function. Background Technology

[0002] A two-way tensioned beam is an elastic support rod of a two-way intersecting planar tensioned beam. The load is transferred to the lower cable-stayed system by the bidirectional upper chord. Since the two-way planar tensioned beams provide each other with out-of-plane elastic constraints, the disadvantage of poor lateral stability of unidirectional tensioned beams is overcome, and the advantages of tensioned beams can be better utilized. However, after the construction of a two-way tensioned beam is completed, it needs to be inspected regularly. This is because the columns of the two-way tensioned beam will become skewed over time due to load and external factors, thus requiring regular inspections, which wastes certain manpower and resources. In addition, the dimensions of the trusses of the existing two-way tensioned beams need to be determined in advance to prevent subsequent assembly failures, which would extend the construction period. Furthermore, because the angle of each truss group in a two-way tensioned beam is different, multiple devices are required to limit the angle before subsequent installation can be completed. Summary of the Invention

[0003] The purpose of this invention is to provide a combined truss connection device with angle adjustment function to solve the problems raised in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a combined truss connection device with angle adjustment function, comprising a double-chord beam body and a controller. The double-chord beam body includes a support component, a positioning component, and a combination component. A support rod is installed between the support component and the combination component. Support rods are respectively installed between the combination component and the positioning component and the parallel combination components in the same direction. The positioning component can limit the length of the double-chord beam. The combination component can cooperate with another set of combination components, support components, and positioning components to assemble the truss. The positioning component can position the position of a single truss and limit the height of the entire double-chord beam.

[0005] Furthermore, the support assembly includes a support block, on the side of which a winding motor and an adjusting motor are mounted. Multiple sets of serrated blocking blocks are provided at the bottom of the fixed end of the support block, and these serrated blocking blocks are not equidistantly installed at the bottom of the support block. A cable groove and an adjusting port are provided at the output end of the support block. Two sets of winding wheels are installed inside the support block, and gears are respectively provided at the ends of the two sets of winding wheels near the winding motor. The output end of the winding motor engages with the gears on the winding wheels. A cable is wound around the winding wheels, and the cable engages with the assembly through the cable groove. An installation cylinder is also installed inside the support block, and the output end of the adjusting motor is connected to the installation cylinder. The output end of the installation cylinder is located between the adjusting ports. A support rod is installed between the installation cylinder and the assembly.

[0006] Furthermore, the positioning component includes a mounting plate, a limiting cylinder mounted on the mounting plate, an opening on one side of the limiting cylinder, a partition between the limiting cylinders, an adjustment component above the partition, a detachable motor mounted below the partition, two sets of limiting grooves and limiting holes on the housing of the detachable motor, a sliding groove on the mounting plate, a limiting rod and a limiting block installed in the sliding groove, the detachable motor cooperating with the sliding groove, and the output end of the detachable motor cooperating with the adjustment component.

[0007] Furthermore, the adjustment assembly includes a limit ring and a drive wheel. The drive wheel is installed above the partition plate, and a mating plate is provided at the bottom of the partition plate. The mating plate mates with the output end of the detachable motor. Multiple sets of levers are installed on the output end of the detachable motor, and multiple sets of slots are formed on the mating plate. The levers and slots mate with each other.

[0008] Furthermore, multiple sets of screws are installed between the limiting ring and the limiting cylinder. These screws are equidistantly installed between the limiting ring and the limiting cylinder. One end of each screw is connected to the inner wall of the limiting cylinder via a bearing, and the other end of each screw is equipped with a driven wheel located on the inner ring of the limiting ring. The driven wheels are respectively engaged with the driving wheel. Limiting rods are installed on each of the screws, and a support plate is installed on the other end of each limiting rod. The support plate is located above the limiting cylinder, and a support cylinder is installed above the support plate.

[0009] Furthermore, the assembly includes a mounting frame, with two sets of limiting plates mounted on top of the mounting frame. A pulley system is provided between the limiting plates. Combination cylinders are installed at both ends inside the mounting frame, and the combination cylinders are connected to the mounting frame via bearings. Two sets of cylinders are installed inside the mounting frame, and the two sets of cylinders cooperate with the two sets of combination cylinders. A support rod is installed between the two sets of combination cylinders. A U-shaped frame is installed outside the mounting frame, and the U-shaped frame is connected to the mounting frame via bearings. A reinforcing cylinder is installed on one side of the U-shaped frame, and a support rod is installed between the two sets of opposing reinforcing cylinders.

[0010] Furthermore, the limiting plates have multiple sets of slots on their adjacent sides, and pressure sensing plates are provided at the bottom of the slots. The pulley assembly is installed between the slots, and the pulley assembly includes multiple sets of rollers. The two ends of the rollers are installed between two opposing sets of slots through bearings, and a cable passes through the rollers.

[0011] Furthermore, a photoelectric sensor is installed on one side of the U-shaped frame with a reinforcing cylinder. Two sets of opposing photoelectric sensors cooperate with each other, and the photoelectric sensor is connected to the controller.

[0012] Furthermore, when the pressure sensing plate and photoelectric sensor data change, the adjustment component adjusts the height of the support rod to match the position of a corresponding set of support rods.

[0013] Furthermore, the controller is installed inside the support block, and a control panel is provided on the outside of the support block, the control panel being connected to the controller.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In the initial stage of construction, the angle of the truss can be adjusted as needed to match the angle of one set with that of another set, or to match the overall curvature with the expected data, so as to complete the most ideal construction. In actual use, the angle of the support rod can be adjusted by combining the components and the support components, and the height of the support rod can be adjusted by the positioning components. Thus, it can be combined with the device to form a double-chord beam main body according to requirements.

[0016] 2. After the assembly is completed, the combined components can monitor the current status of the double-chord beam body in real time. In actual use, because the double-chord beam body is limited and supported by cables, the pulley system on the combined components can detect the pressure applied by the cables, and thus the status of the combined components can be detected based on the pressure. Furthermore, the photoelectric sensor on the side of the combined components can detect a relative set of combined components. When the combined components are displaced, the photoelectric sensor can immediately transmit the signal to the controller.

[0017] 3. When a component is detected to have a slight offset or sinking, the positioning component can quickly adjust the slight offset or sinking to prevent the initial defect from expanding and causing irreparable damage. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example: As shown in Figures 1-9, the present invention provides a technical solution for a combined truss connection device with angle adjustment function, including a double-chord beam body 1 and a controller 6. The double-chord beam body 1 includes a support component 2, a positioning component 3 and a combination component 4. A support rod is installed between the support component 2 and the combination component 4. Support rods are respectively installed between the combination component 4 and the positioning component 3 and the parallel combination component 4 in the same direction. The positioning component 3 can limit the length of the double-chord beam. The combination component 4 can cooperate with another set of combination components 4, support components 2 and positioning components 3 to assemble the truss. The positioning component 3 can position the position of a single truss and limit the height of the entire double-chord beam.

[0030] When using this device, firstly, sufficient support components 2, positioning components 3, and assembly components 4 need to be prepared according to requirements. These components together form the main body 1 of the double-chord beam. Specifically, the required length of the double-chord beam must first be determined. Then, the support components 2 are installed at the required positions according to the desired length, thus defining the overall length of the double-chord beam. Multiple sets of positioning components 3 and assembly components 4 are installed on multiple sets of support components 2. Before this, the assembly components 4 need to be connected to the positioning components 3 via support rods, with two sets of support rods installed on both sides of the assembly components 4. The angles of the two sets of support rods can then be controlled by manipulating the assembly components 4 as needed, thus assisting in subsequent assembly. The assembled support component 2, combination component 4, and positioning component 3 are then connected together to form a single chord beam. The two chord beams can be reinforced by multiple sets of support rods. By connecting the two opposing combination components 4 with the support rods, the cable on the support component 2 can be connected to the opposing support component 2 via the combination component 4, thus forming the complete double chord beam body 1. After assembly, the device can monitor itself and determine its current status. If a slight deviation or subsidence is detected, the device can correct itself. The staff can observe this through the log of the controller 6 and carry out precise maintenance, thereby saving manpower and materials.

[0031] As shown in Figures 1-3, in this embodiment, specifically, the support component 2 includes a support block 21. A winding motor 22 and an adjusting motor 23 are installed on the side of the support block 21. Multiple sets of sawtooth-shaped blocking blocks are provided at the bottom of the fixed end of the support block 21. The multiple sets of sawtooth-shaped blocking blocks are installed at non-equidistant intervals at the bottom of the support block 21. A cable groove and an adjusting port are provided at the output end of the support block 21. Two sets of winding wheels 24 are installed inside the support block 21. Gears are respectively provided at the ends of the two sets of winding wheels 24 near the winding motor 22. The output end of the winding motor 22 cooperates with the gears on the winding wheels 24. A cable is wound on the winding wheels 24. The cable cooperates with the combined component 4 through the cable groove. An installation cylinder 25 is also installed inside the support block 21. The output end of the adjusting motor 23 is connected to the installation cylinder 25. The output end of the installation cylinder 25 is located between the adjusting ports. A support rod is installed between the installation cylinder 25 and the combined component 4.

[0032] When in use, the support component 2 of this device can limit the length and position of the entire double-chord beam, and at the same time stabilize the double-chord beam body 1. In specific use, two sets of support components 2 can form a single double-chord beam, while four sets in four directions can form a complete double-chord beam body 1. When the position of the entire double-chord beam body 1 is determined, the four sets of support components 2 need to be installed in the predetermined position. The serrated blocking block can better limit the position of the support components 2 and prevent the support components 2 from shifting due to strong cable tension. The cables in the two opposing support components 2 are limited by the winding wheel 24, and the winding wheel 24 can tighten the cables. The mounting cylinder 25 on the support component 2 can change the angle of the mounting cylinder 25 by adjusting the motor 23 after the support rod is installed, thereby changing the angle of the support rod to cooperate with the assembly component 4 for assembly. Thus, this device can limit the position of the support component 2 and can adjust the current angle of the support rod as needed to facilitate subsequent assembly.

[0033] As shown in Figures 2-5 and 9, in this embodiment, specifically, the positioning component 3 includes a mounting plate 31, a limiting cylinder 32 mounted on the mounting plate 31, an opening on one side of the limiting cylinder 32, a partition 33 installed between the limiting cylinders 32, an adjustment component 5 above the partition 33, and a detachable motor 34 installed below the partition 33. The detachable motor 34 has two sets of limiting grooves and limiting holes on its outer shell. The mounting plate 31 has a sliding groove, in which a limiting rod 55 and a limiting block are installed. The detachable motor 34 cooperates with the sliding groove, and the output end of the detachable motor 34 cooperates with the adjustment component 5.

[0034] When in use, the positioning component 3 of this device can limit the height and curvature of the double-chord beam body 1, and also plays a major supporting role. In specific use, the mounting plate 31 can limit the positioning component 3, and the weight of the positioning component 3 can be distributed to the ground through the mounting plate 31. Because the mounting plate 31 has a large area, it can bear more weight and improve the stability of the positioning component 3. The limiting cylinder 32 can protect the adjustment component 5 inside. The adjustment component 5 plays an important role in installation and subsequent maintenance. During installation, the support rod can be finely adjusted according to the current height for installation. In subsequent use, if the support rod tilts slightly, it will be corrected in conjunction with the combination component 4, and the record will be transmitted to the controller 6 for subsequent maintenance by the staff. Furthermore, because the driving component at the bottom of the device is a detachable motor 34, the equipment can be disassembled more conveniently during maintenance.

[0035] As shown in Figures 2-5 and 9, in this embodiment, specifically, the adjustment component 5 includes a limit ring 51 and a drive wheel 52. The drive wheel 52 is installed above the partition 33. The drive wheel 52 is located at the bottom of the partition 33 and is provided with a mating plate 521. The mating plate 521 is mated with the output end of the detachable motor 34. Multiple sets of levers are installed on the output end of the detachable motor 34. Multiple sets of slots are opened on the mating plate 521. The levers and slots are mated with each other.

[0036] In practical use, the detachable motor 34 can drive the drive wheel 52 to rotate. This is because the output end of the detachable motor 34 is equipped with multiple levers, and the mating plate 521 at the bottom of the drive wheel 52 is provided with matching slots. When the output end of the detachable motor 34 is installed together with the mating plate 521, the rotation of the detachable motor 34 will drive the drive wheel 52 to rotate, which in turn drives other mating components to facilitate subsequent operations.

[0037] As shown in Figure 9, in this embodiment, specifically, multiple sets of screws 53 are installed between the limiting ring 51 and the limiting cylinder 32. The multiple sets of screws 53 are equidistantly installed between the limiting ring 51 and the limiting cylinder 32. One end of each screw 53 is connected to the inner wall of the limiting cylinder 32 through a bearing. The other end of each screw 53 is located on the inner ring of the limiting ring 51 and is equipped with a driven wheel 54. The multiple sets of driven wheels 54 are respectively engaged with the driving wheel 52. Limiting rods 55 are respectively installed on the multiple sets of screws 53. A support plate 56 is installed on the other end of each limiting rod 55. The support plate 56 is located above the limiting cylinder 32, and a support cylinder 45 is installed above the support plate 56.

[0038] When the detachable motor 34 rotates, it drives the drive wheel 52 to rotate. The drive wheel 52 cooperates with multiple sets of driven wheels 54, which in turn drive the multiple sets of driven wheels 54 to rotate. Since the driven wheels 54 are connected to the screw 53, they can also drive the screw 53 to rotate, which in turn drives the limit rod 55 on the screw 53 to move. When the detachable motor 34 rotates forward, the limit rod 55 moves towards the limit ring 51, and vice versa. When the limit rod 55 moves closer to the limit ring 51, the support plate 56 at the other end of the limit rod 55 is raised. Since the support plate 56 is provided with a support cylinder 45, which can install and support the support rod, raising the support plate 56 will raise the height of the support rod, and vice versa.

[0039] As shown in Figures 7 and 8, in this embodiment, specifically, the combined component 4 includes a mounting frame 41, two sets of limiting plates 42 are mounted on the top of the mounting frame 41, a pulley system is provided between the limiting plates 42, a combined cylinder 43 is mounted at both ends inside the mounting frame 41, the combined cylinder 43 is connected to the mounting frame 41 through bearings, two sets of cylinders are mounted inside the mounting frame 41, the two sets of cylinders cooperate with the two sets of combined cylinders 43, a support rod is installed between the two sets of combined cylinders 43, a U-shaped frame 44 is mounted on the outside of the mounting frame 41, the U-shaped frame 44 is connected to the mounting frame 41 through bearings, a reinforcing cylinder 57 is mounted on one side of the U-shaped frame 44, and a support rod is installed between the two sets of opposite reinforcing cylinders 57;

[0040] The assembly component 4 ensures that the final double-chord beam meets the expected curvature requirements. The pulley system is used to limit the cable and control the pressure applied by the cable. Based on the changes in the pressure applied by the cable, it is easy for workers to determine whether the double-chord beam body 1 needs maintenance. The assembly cylinders 43 on both sides of the mounting frame 41 can also install the support rods. Because there are cylinders at the bottom, the assembly cylinders 43 can be pushed as needed to adjust the position of the support rods, which is convenient for subsequent assembly work. The U-shaped frame 44 will change its current position under the action of gravity, so that the U-shaped frame 44 can always be perpendicular to the ground. Due to the curvature of the double-chord beam body 1, the position and tilt angle of each assembly component 4 may be different, but each U-shaped frame 44 will always remain vertical to cooperate with the positioning component 3. The reinforcing cylinders 57 on the side of the U-shaped frame 44 are used to increase the support force between the two sets of double-chord beams and prevent the double-chord beam body 1 from collapsing.

[0041] As shown in Figure 8, in this embodiment, specifically, the limiting plates 42 have multiple sets of slots 421 on their close sides. A pressure sensing plate is provided at the bottom of each slot 421. The pulley group is installed between the slots 421. The pulley group includes multiple sets of rollers. The two ends of each roller are installed between two opposing slots 421 through bearings. A cable passes through the roller.

[0042] After the setup is completed, the pressure sensing plate can monitor the force of the cable acting on the pulley block in real time. When the force increases, it means that one of the current multiple positioning components 3 has become skewed, causing the pressure on the adjacent positioning component 3 to increase. When the pressure of one of the components is small, it means that it has become skewed to varying degrees. Then the controller 6 will control the adjustment component 5 to adjust the current state of the support rod.

[0043] As shown in Figure 7, in this embodiment, specifically, a photoelectric sensor is installed on one side of the U-shaped frame 44 with a reinforcing cylinder 57, and two sets of opposing photoelectric sensors cooperate with each other. The photoelectric sensor is connected to the controller 6.

[0044] When the two sets of photoelectric sensors deviate, it indicates that one or both sets of support rods are tilted or sinking. The controller 6 can then quickly remedy and correct the situation to prevent further damage.

[0045] As shown in Figures 2, 7, and 9, in this embodiment, specifically, when the pressure sensing plate and photoelectric sensor data change, the adjusting component 5 adjusts the height of the support rod to match the position of a corresponding set of support rods;

[0046] Furthermore, based on the data transmitted to the controller 6 by the pressure sensing plate and photoelectric sensor of the device, it is possible to accurately determine which group of positioning components 3 has a problem and correct the problem, thereby preventing personal injury and property damage.

[0047] As shown in Figure 2, in this embodiment, the controller 6 is installed inside the support block 21, and a control panel is provided on the outside of the support block 21. The control panel is connected to the controller 6.

[0048] When in use, the controller 6 can monitor each component of the device, while the staff can check the system logs on the control panel and then perform further maintenance on any problems that occur.

[0049] Working Principle: When using this device, firstly, sufficient support components 2, positioning components 3, and assembly components 4 need to be prepared according to requirements. These components together form the main body 1 of the double-chord beam. Specifically, the required length of the double-chord beam needs to be determined first. Then, the support components 2 are installed at the required positions according to the desired length, thus defining the overall length of the double-chord beam. Multiple sets of positioning components 3 and assembly components 4 are installed on multiple sets of support components 2. Before this, the assembly components 4 need to be connected to the positioning components 3 via support rods, with two sets of support rods installed on both sides of the assembly components 4. The angle of the two sets of support rods can then be controlled by manipulating the assembly components 4 as needed, thereby assisting in subsequent operations. After assembly, the assembled support component 2, combination component 4, and positioning component 3 are connected together to form a single chord beam. The two chord beams can be reinforced by multiple sets of support rods. Simply connect the two opposing combination components 4 through the support rods, and then connect the cable on the support component 2 to the opposing support component 2 through the combination component 4 to form a complete double chord beam body 1. After the device is assembled, it can monitor itself and determine its current status. When a slight deviation or sinking is detected, the device can correct itself. The staff can observe this through the log of the controller 6 and carry out precise maintenance afterwards, thereby saving manpower and materials.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
