Description

Technical Field

[0002] The bidirectional beam string is an elastic support rod of a plane beam string that intersects in two directions. The load is transmitted to the lower cable support system by the upper chord arranged in two directions. Since the plane beam string in two directions provides each other with out-of-plane elastic constraints, the disadvantage of poor lateral stability of the unidirectional beam string is overcome, and the advantages of the beam string can be better utilized. However, after the construction of the bidirectional beam string is completed, the bidirectional beam string needs to be regularly inspected and maintained, because the columns of the bidirectional beam string will be deflected due to the load-bearing and external factors for a long time, and the bidirectional beam string needs to be regularly inspected and maintained, which will waste a certain amount of manpower and material resources. In addition, the existing bidirectional beam string needs to first determine the size of the truss to prevent the subsequent assembly from being unable to occur, thereby extending the construction period. In addition, because the angles of each group of trusses of the bidirectional beam string are different, multiple devices are required to limit the angle before the subsequent installation can be completed.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example: Figure 1-Figure 9 As shown, the present invention provides a technical solution of a combined truss connection device with an angle adjustment function, including a double-chord beam body 1 and a controller 6, the double-chord beam body 1 includes a support assembly 2, a positioning assembly 3 and a combined assembly 4, a support rod is installed between the support assembly 2 and the combined assembly 4, and a support rod is installed between the combined assembly 4 and the positioning assembly 3 and the combined assembly 4 in the same direction and parallel to each other, the positioning assembly 3 can limit the length of the double-chord beam, the combined assembly 4 can cooperate with another group of combined assemblies 4, the support assembly 2 and the positioning assembly 3 to assemble a truss, and the positioning assembly 3 can locate the position of a single truss and limit the height of the entire double-chord beam;

[0030] When the device is in use, it is first necessary to prepare sufficient support components 2, positioning components 3 and combination components 4 according to needs, and the double-chord beam body 1 is composed of sufficient support components 2, positioning components 3 and combination components 4. When it is used specifically, it is first necessary to determine the required length of the double-chord beam, and then install the support component 2 to the required position according to the required length, thereby limiting the length of the entire double-chord beam, and installing multiple groups of positioning components 3 and combination components 4 on multiple groups of support components 2. However, before that, it is necessary to connect the combination component 4 with the positioning component 3 through a support rod, and install the two groups of support rods on both sides of the combination component 4. After that, the combination component 4 can be manipulated to control the angles of the two groups of support rods as needed, thereby assisting subsequent assembly. Afterwards, the assembled support component 2, combination component 4 and positioning component 3 are connected to each other to form a single chord beam, and the two groups of chord beams can be reinforced by multiple groups of support rods. It is only necessary to connect the two groups of relative combination components 4 through the support rods, and then the cables on the support component 2 can be connected to the relative group of support components 2 through the combination component 4 to form a complete double-chord beam body 1. After the assembly is completed, the device can monitor itself and determine its current state by itself. When a slight deviation or sinking is detected, the device can correct itself. The staff can observe this through the controller 6 log and perform precise maintenance later, thereby saving manpower and materials.

[0031] like Figure 1-Figure 3 As shown, in the present embodiment, specifically, the support assembly 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, a plurality of groups of serrated blocking blocks are arranged at the bottom of the fixed end of the support block 21, and the plurality of groups of serrated blocking blocks are unequally installed 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 groups of winding wheels 24 are installed inside the support block 21, and gears are respectively arranged at one end of the two groups of winding wheels 24 close to the winding motor 22, the output end of the winding motor 22 cooperates with the gear on the winding wheel 24, a cable is wound around the winding wheel 24, and the cable cooperates with the combination assembly 4 through the cable groove, a mounting cylinder 25 is also installed inside the support block 21, the output end of the adjusting motor 23 is connected to the mounting cylinder 25, the output end of the mounting cylinder 25 is located between the adjusting ports, and a support rod is installed between the mounting cylinder 25 and the combination assembly 4;

[0032] When in use, the support assembly 2 of the 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. When in use, two groups of support assemblies 2 can form a single double-chord beam, and four groups 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 groups of support assemblies 2 need to be installed to the predetermined position. The position of the support assembly 2 can be better limited by the serrated blocking block to prevent the cable tension from being too strong and causing the support assembly 2 to deviate. The cables of the two opposite groups of support assemblies 2 will be limited by the winding wheel 24, and the winding wheel 24 can tighten the cables. The mounting cylinder 25 on the support assembly 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 so as to cooperate with the combination assembly 4 for assembly. The device can limit the position of the support assembly 2 and adjust the current angle of the support rod as needed to facilitate subsequent assembly.

[0033] like Figure 2-Figure 5 and Fig. 9 As shown, in this embodiment, specifically, the positioning assembly 3 includes a mounting plate 31, a limiting cylinder 32 is installed on the mounting plate 31, an opening is opened on one side of the limiting cylinder 32, a partition 33 is installed between the limiting cylinders 32, an adjustment assembly 5 is arranged above the partition 33, a detachable motor 34 is installed below the partition 33, two groups of limiting grooves and limiting holes are opened on the outer shell of the detachable motor 34, a slide groove is arranged on the mounting plate 31, a limiting rod 55 and a limiting block are installed in the slide groove, the detachable motor 34 cooperates with the slide groove, and the output end of the detachable motor 34 cooperates with the adjustment assembly 5;

[0034] When in use, the positioning component 3 of the 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 mounting plate 31 can disperse the weight of the positioning component 3 to the ground. 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 therein, and the adjustment component 5 can play an important role during installation and subsequent maintenance. During installation, the support rod can be fine-tuned according to the current height for installation. In subsequent use, when the support rod is slightly tilted, it will cooperate with the combination component 4 to remedy it, and the record will be transmitted to the controller 6 for subsequent maintenance by the staff. And because the driving member at the bottom of the device is a detachable motor 34, the equipment can be more conveniently disassembled during maintenance.

[0035] like Figure 2-Figure 5 and Fig. 9As shown, in this embodiment, specifically, the adjustment component 5 includes a limit ring 51 and a driving wheel 52, the driving wheel 52 is installed above the partition 33, the driving wheel 52 is located at the bottom of the partition 33 and is provided with a matching plate 521, the matching plate 521 is matched with the output end of the detachable motor 34, the output end of the detachable motor 34 is equipped with multiple groups of levers, the matching plate 521 is provided with multiple groups of slots, and the levers and slots are matched with each other;

[0036] When the adjustment component 5 is in use, the detachable motor 34 can drive the driving wheel 52 to rotate, because the output end of the detachable motor 34 is equipped with multiple sets of levers, and the matching plate 521 at the bottom of the driving wheel 52 is provided with matching grooves. When the output end of the detachable motor 34 and the matching plate 521 are installed together, the rotation of the detachable motor 34 will drive the driving wheel 52 to rotate, and then drive other matching components through the driving wheel 52, so as to facilitate subsequent operations.

[0037] like Fig. 9 As shown, in this embodiment, specifically, multiple groups of screw rods 53 are installed between the limiting ring 51 and the limiting cylinder 32, and the multiple groups of screw rods 53 are equidistantly installed between the limiting ring 51 and the limiting cylinder 32, one end of the screw rod 53 is connected to the inner wall of the limiting cylinder 32 through a bearing, and the other end of the screw rod 53 is located in the limiting ring 51. The inner ring is equipped with a driven wheel 54, and the multiple groups of driven wheels 54 are respectively matched with the driving wheel 52. The multiple groups of screw rods 53 are respectively equipped with limiting rods 55, and the other end of the limiting rod 55 is equipped with a support plate 56, and the support plate 56 is located above the limiting cylinder 32, and the support cylinder 45 is installed above the support plate 56;

[0038] When the detachable motor 34 rotates, the driving wheel 52 will be driven to rotate, and the driving wheel 52 cooperates with multiple groups of driven wheels 54, thereby driving multiple groups of driven wheels 54 to rotate. Because the driven wheel 54 is connected to the screw rod 53, it can rotate together with the screw rod 53, thereby driving the limiting rod 55 on the screw rod 53 to move; when the detachable motor 34 rotates forward, the limiting rod 55 will move toward the limiting ring 51, otherwise it will move toward the inner wall of the limiting cylinder 32, and then when the limiting rod 55 is close to the limiting ring 51, the support plate 56 at the other end of the limiting rod 55 will be lifted, and because the support plate 56 is provided with a support cylinder 45, and the support cylinder 45 can install and support the support rod, the lifting of the support plate 56 will raise the height of the support rod, and vice versa.

[0039] like Figure 7-Figure 8As shown, in this embodiment, specifically, the combination component 4 includes a mounting frame 41, two groups of limit plates 42 are installed on the top of the mounting frame 41, a pulley group is arranged between the limit plates 42, and combination cylinders 43 are respectively installed at both ends of the inside of the mounting frame 41, and the combination cylinders 43 are connected to the mounting frame 41 through bearings, and two groups of cylinders are installed in the mounting frame 41, and the two groups of cylinders cooperate with the two groups of combination cylinders 43. A support rod is installed between the two groups of combination cylinders 43, and a U-shaped frame 44 is installed outside the mounting frame 41, and the U-shaped frame 44 is connected to the mounting frame 41 through bearings, and a reinforcement cylinder 57 is installed on one side of the U-shaped frame 44, and a support rod is installed between two groups of opposite reinforcement cylinders 57;

[0040] The combined component 4 can ensure whether the final finished double-chord beam can meet the expected curvature requirements, and the pulley block is a component used to limit the cable, and can be the pressure applied by the current cable. According to the change in the pressure applied by the cable, it is convenient for the staff to judge whether the double-chord beam body 1 needs maintenance, and the combined cylinders 43 on both sides of the installation frame 41 can also install the support rods, and because a cylinder is provided at the bottom, the combined cylinder 43 can be pushed as needed to adjust the position of the support rod, which is convenient for subsequent assembly work, and the U-shaped frame 44 will change its current position by itself under the action of gravity, so that the U-shaped frame 44 can always be perpendicular to the ground. Because of the curvature of the double-chord beam body 1, the position and inclination angle of each group of combined components 4 may be different, but each group of U-shaped frames 44 will always remain in a vertical state to cooperate with the positioning component 3. The reinforcement cylinder 57 on the side of the U-shaped frame 44 is to increase the supporting force between the two groups of double-chord beams to prevent the double-chord beam body 1 from collapsing.

[0041] like Figure 8 As shown, in this embodiment, specifically, a plurality of groups of slots 421 are provided on one side of the limit plate 42 close to each other, a pressure sensing plate is provided at the bottom of the slots 421, the pulley group is installed between the slots 421, the pulley group includes a plurality of groups of rollers, both ends of the rollers are installed between two opposite groups of slots 421 through bearings, and a cable passes through the rollers;

[0042] After the construction is completed, the force of the cable acting on the pulley block can be monitored in real time through the pressure sensing plate. When the force increases, it means that one of the multiple groups of positioning components 3 is skewed, resulting in increased pressure on the adjacent group of positioning components 3. When the pressure on one group is smaller, it means that it has different degrees of skewness, and then the controller 6 will control the adjustment component 5 to adjust the state of the current support rod.

[0043] like Figure 7As shown, in this embodiment, specifically, the U-shaped frame 44 is provided with a photoelectric sensor installed on one side of the reinforcement tube 57, and two sets of opposite photoelectric sensors cooperate with each other, and the photoelectric sensor is connected to the controller 6;

[0044] When the two groups of photoelectric sensors are offset, it means that one or both groups of support rods are currently tilted or sunken, and the controller 6 can quickly remedy and correct it to prevent greater losses.

[0045] like Figure 2 , Figure 7 and Fig. 9 As shown, in this embodiment, specifically, when the data of the pressure sensing plate and the photoelectric sensor change: the adjustment component 5 adjusts the height of the support rod to match the position of a corresponding group of support rods;

[0046] Furthermore, based on the data transmitted to the controller 6 by the pressure sensing plate and the 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 loss at the same time.

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

[0048] When the device is in use, the various components of the device can be monitored through the controller 6, and the staff can check the system log according to the control panel, and then further maintenance can be carried out on the problematic parts.

[0049] Working principle: When using the device, firstly, it is necessary to prepare enough support components 2, positioning components 3 and combination components 4 according to the needs, and the double-chord beam body 1 is composed of enough support components 2, positioning components 3 and combination components 4. When using it specifically, it is necessary to first determine the required length of the double-chord beam, and then install the support component 2 to the required position according to the required length, thereby limiting the length of the entire double-chord beam, and installing multiple groups of positioning components 3 and combination components 4 on multiple groups of support components 2. However, before that, it is necessary to connect the combination component 4 with the positioning component 3 through a support rod, and install the two groups of support rods on both sides of the combination component 4. After that, the combination component 4 can be manipulated to control the angles of the two groups of support rods as needed, thereby assisting the subsequent After the assembly, the assembled support component 2, the combination component 4 and the positioning component 3 are connected to each other to form a single string beam, and the two groups of string beams can be reinforced by multiple groups of support rods. It is only necessary to connect the two groups of relative combination components 4 through the support rods, and then the cables on the support component 2 can be connected to the relative group of support components 2 through the combination component 4 to form a complete double-string beam body 1. After the assembly is completed, the device can monitor itself and determine its current state by itself. When a slight deviation or sinking is detected, the device can correct itself. The staff can observe this through the controller 6 log and perform precise maintenance later, thereby saving manpower and materials.

[0050] It will be apparent to those skilled in the art that the 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 the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
