Description

Technical Field

[0001] The invention belongs to the technical field of steel structure truss assembly, and particularly relates to an adaptive integrated assembly device for truss processing. Background Technique

[0002] Steel structure is a structure composed of steel materials and is one of the main building structure types, which is widely used in large factories, bridges, stadiums, super high-rise buildings and other fields. A truss is a load-bearing structure that can achieve large space and large span, and at the same time has a simple and beautiful shape. Because of its many advantages such as large span, light weight, high strength, and good seismic resistance, its application range is becoming more and more extensive. At present, during assembly, basically, steel pipes are placed on a support frame temporarily welded by H-shaped steel for operation;

[0003] In the prior art, the Chinese utility model content with the application number: CN202122524497.5 discloses a truss assembly device that is easy to adjust. The technical solution is as follows: it includes a rectangular bottom plate, vertical columns are respectively arranged at both ends of the upper surface of the bottom plate, a slide rail is fixedly arranged on one side of each column, a pulley is rotatably arranged at the upper end of each column, a winch is fixedly arranged on the upper surface of the bottom plate, the steel wire rope of the winch bypasses the pulley and extends to one side of the column, one end of the steel wire rope is fixedly connected to a lifting frame, and a number of positioning balls are arranged in an array at one end of the steel wire rope close to the winch; the lifting frame includes a sliding plate slidably connected to the slide rail, a horizontal plate is fixedly arranged at the upper end of the sliding plate, and an inclined support plate is fixedly arranged between the horizontal plate and the sliding plate. The structure of this utility model is simple and easy to use, is suitable for trusses with different heights and spans, can be flexibly moved according to the actual conditions of the construction site, reduces the time for truss assembly, and improves the efficiency of truss assembly;

[0004] Although the truss splicing device in the prior art can realize the splicing of the truss, however, during the truss splicing process, it is necessary for workers to continuously manually adjust the alignment of the truss. The operation steps are relatively complicated during the alignment process of two groups of trusses, and the splicing efficiency of the truss needs to be further improved. Moreover, no buffer structure is set during the manual alignment process, and collisions may occur during the truss alignment process, resulting in structural damage. The protection effect during the truss splicing process needs to be further improved. Therefore, we need to propose an adaptive integrated assembly device for truss processing.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figures 1-10 shown, an adaptive integrated assembly device for truss processing provided by an embodiment of the present invention includes:

[0039] A connecting chassis 1, and moving frames 4 detachably arranged on both sides of the connecting chassis 1. An alignment mechanism 5 for adjusting the position of the truss is arranged above the moving frames 4. Two groups of alignment mechanisms 5 are arranged on the same axis. A support mechanism 6 for supporting the truss is arranged on the alignment mechanism 5. A positioning mechanism 7 for fixing the truss is installed below the support mechanism 6. An auxiliary unloading mechanism 22 for lifting the truss is arranged between the positioning mechanism 7 and the support mechanism 6.

[0040] As Figure 3As shown in the figure, a bottom groove 10 is formed on the upper surface of the connecting chassis 1. A passive polishing mechanism 11 for polishing the splicing end of the truss is arranged in the bottom groove 10. A bracket 3 is fixedly connected to the upper surface of the connecting chassis 1. A plurality of groups of baffles 14 are fixedly connected to both sides of the inner cavity of the bracket 3. One end of the support mechanism 6 close to the connecting chassis 1 is provided with a buffer mechanism 8. Two groups of monitoring cameras 13 and photoelectric switches 12 are symmetrically arranged at the upper end of the bracket 3. An integrated controller 2 is arranged on one side of the connecting chassis 1 adjacent to the moving frame 4.

[0041] As Figure 3 and Figure 10 As shown in the figure, the buffer mechanism 8 includes a ladder block 81, two groups of connecting sleeve rods 83 and a buffer plate 85. The two ends of the two groups of connecting sleeve rods 83 are respectively fixedly connected to the opposite sides of the ladder block 81 and the buffer plate 85. Gaskets 82 are arranged at both ends of the two groups of connecting sleeve rods 83. Buffer springs 84 are sleeved on the outer sides of the two groups of connecting sleeve rods 83 and are located between the two groups of gaskets 82. A distance sensor 86 is arranged on one side of the buffer plate 85. A pressure sensor 15 is arranged on one side of the baffle 14. The distance between the alignment mechanism 5 and the connecting chassis 1 is monitored by the distance sensor 86, so that it is convenient for the distance sensor 86 to send a signal to the integrated controller 2 and control the start and stop of the first motor 54 through the integrated controller 2. The distance sensor 86 and the pressure sensor 15 monitor the position and force condition of the buffer plate 85 in real time and feedback to the integrated controller 2 for adjustment, improving the automation degree of the device. At the same time, when the two trusses are spliced, the buffer springs 84 on the connecting sleeve rods 83 are compressed by the ladder block 81 and the buffer plate 85, so as to avoid the rigid contact between the two trusses and improve the protection effect on the trusses.

[0042] As Figures 1-2 As shown in the figure, the alignment mechanism 5 includes a bottom plate 51 fixed on the moving frame 4. An adjustable distance screw 53 is rotatably arranged on the upper surface of the bottom plate 51. One end of the adjustable distance screw 53 penetrates through the bottom plate 51 and is driven by a first motor 54. Two groups of first guide beams 52 parallel to the adjustable distance screw 53 are fixedly connected to the upper surface of the bottom plate 51. The first motor 54 drives the adjustable distance screw 53 to conveniently adjust the position of the support mechanism 6, so as to conveniently drive the position adjustment of the truss, further improving the splicing efficiency of the truss and realizing the precise adjustment of the position of the truss to ensure the splicing accuracy.

[0043] As Figures 2-3As shown, a positioning iron plate 20 and two sets of alignment guide rods 21 are provided on the side of the bottom plate 51 opposite to the first motor 54, and electromagnets 18 that are magnetically attracted to the positioning iron plate 20 are provided on both sides of the connecting chassis 1, and alignment holes 19 for the alignment guide rods 21 to be plugged into are provided on both sides of the connecting chassis 1. The alignment guide rods 21 can be quickly plugged into the alignment holes 19 on the connecting chassis 1, so that the two sets of alignment mechanisms 5 are arranged on the same axis, ensuring that the spliced ​​trusses are located on the same axis, improving the accuracy of splicing, and under the action of the electromagnet 18 and the positioning iron plate 20, the stability of the connection between the connecting chassis 1 and the alignment mechanism 5 is improved, and the sliding of the alignment mechanism 5 during the truss splicing process is avoided.

[0044] like Figures 5-6 As shown, the support mechanism 6 includes a sliding seat 61 slidably arranged between two groups of first guide beams 52, and multiple groups of columns 62 are fixedly connected to the upper surface of the sliding seat 61. The upper ends of the multiple groups of columns 62 are fixedly mounted with a base plate 63, and the upper surface of the mounting base plate 63 is provided with a storage groove 65 for accommodating two groups of auxiliary unloading mechanisms 22. The lower surface of the mounting base plate 63 is symmetrically fixedly connected with a fixed block 64 for installing the positioning mechanism 7. The support mechanism 6 can support trusses of different specifications, thereby improving the stability of the truss during splicing.

[0045] like Figure 2 , 8 As shown in Figure 9, the positioning mechanism 7 includes a first dual-axis motor 71 and two groups of clamping members 74. The first dual-axis motor 71 is installed in the middle of the lower surface of the mounting base plate 63. The two groups of output ends of the first dual-axis motor 71 are both drivingly connected with the first screw rod 72. The opposite ends of the two groups of first screw rods 72 are respectively threadedly connected with the two groups of clamping members 74, and the opposite ends of the two groups of first screw rods 72 are respectively rotatably set on the opposite sides of the two groups of fixed blocks 64. Two groups of stable telescopic sleeve rods 73 are fixedly connected between the two groups of clamping members 74. The first dual-axis motor 71 drives the first screw rod 72 to adjust the spacing of the clamping members 74, so that the clamping members 74 can be conveniently used to position trusses of different specifications, thereby improving the stability of the truss splicing process. At the same time, the design of the stable telescopic rod is used to improve the stability of the two groups of clamping members 74 during relative movement, ensuring that the clamping members 74 stably clamp the truss.

[0046] like Figure 9As shown, the clamping member 74 includes a moving beam 741 threadedly connected to the first screw 72. At both ends of one side of the moving beam 741, special-shaped frames 742 are fixedly connected. At the upper end of the special-shaped frame 742, a clamping plate 744 located above the mounting substrate 63 is fixedly connected. A reinforcing block 743 is arranged between the special-shaped frame 742 and the clamping plate 744. The stability of the movement of the clamping plate 744 is improved by the special-shaped frame 742, and the service life of the clamping plate 744 is increased by the reinforcing block 743, avoiding deformation of the clamping plate 744. A non-slip pad is arranged on the side of the clamping plate 744 in contact with the truss, protecting the surface of the truss and preventing sliding during the splicing of the truss.

[0047] As Figure 4 shown, the passive polishing mechanism 11 includes a lifting assembly 111 arranged at the bottom of the bottom groove 10. At the upper end of the lifting assembly 111, an adjusting assembly 112 is arranged. A polishing assembly 113 for polishing the docking end of the truss is arranged on the adjusting assembly 112. The height of the polishing assembly 113 can be conveniently adjusted by the lifting assembly 111, so as to conveniently polish the splicing end faces of trusses of different specifications. The horizontal position of the polishing assembly 113 can be conveniently adjusted by the adjusting assembly 112, so as to conveniently polish any position of the truss splicing surface and improve the flatness of the truss splicing end face.

[0048] The lifting assembly 111 includes a lifting cylinder 1111, two groups of auxiliary sleeve rods 1112 and a mounting frame 1113. The telescopic end of the lifting cylinder 1111 and the upper ends of the two groups of auxiliary sleeve rods 1112 are fixedly connected to the inner top of the mounting frame 1113. Two groups of second guide beams 1114 are fixedly connected to the upper surface of the mounting frame 1113. The height of the mounting frame 1113 is adjusted by the lifting cylinder 1111, and the stable lifting of the mounting frame 1113 is ensured under the action of the auxiliary sleeve rods 1112, so as to ensure the movement stability of the polishing assembly 113.

[0049] The adjusting assembly 112 includes a second motor 1121 and a reciprocating screw 1123. The reciprocating screw 1123 is rotatably arranged above the mounting frame 1113. One end of the reciprocating screw 1123 is fixedly connected with a driven gear 1124. The second motor 1121 is installed on the inner top of the mounting frame 1113. The output shaft of the second motor 1121 is drivingly connected with a driving gear shaft 1122. The gear part of the driving gear shaft 1122 meshes with the driven gear 1124. The other end of the reciprocating screw 1123 is threadedly connected with a T-shaped plate 1125, and the T-shaped plate 1125 is slidably arranged between the two groups of second guide beams 1114. The driving gear shaft 1122 is driven by the second motor 1121 to rotate, so that the driving gear shaft 1122 meshes with the driven gear 1124 on the reciprocating screw 1123, so that the reciprocating screw 1123 drives the T-shaped plate 1125 to reciprocate along the second guide beam 1114, realizing the rapid polishing of the truss splicing end face by the polishing assembly 113.

[0050] The polishing assembly 113 includes a second dual-axis motor 1131 installed above the T-plate 1125. The two sets of output ends of the second dual-axis motor 1131 are both transmission-connected with elastic sleeve rods 1132. The opposite ends of the two sets of elastic sleeve rods 1132 are each provided with a polishing disk 1133 for polishing the spliced ​​ends of the trusses. The elastic sleeve rods 1132 mainly consist of a connecting shaft and a mounting sleeve. The connecting shaft is connected to the output shaft of the second dual-axis motor 1131. A return spring that contacts the connecting shaft is arranged in the mounting sleeve. The elastic sleeve rods 1132 can enable the polishing assembly 113 to polish the spliced ​​end faces of the two sets of trusses at different intervals, thereby improving applicability.

[0051] like Figure 5 and Figure 7 As shown, the auxiliary unloading mechanism 22 includes a supporting cylinder 221 and two sets of limiting sleeve rods 222 installed on the upper surface of the sliding seat 61. The telescopic end of the supporting cylinder 221 and the upper ends of the two sets of limiting sleeve rods 222 are fixedly connected with a top plate 223. Two sets of through grooves are opened on the upper surface of the top plate 223, and guide rollers 224 are rotatably arranged in the two sets of through grooves. The position of the top plate 223 is adjusted by the lifting cylinder 1111, so as to facilitate the contact between the guide roller 224 and the truss, and facilitate the picking and placing of the truss before and after splicing.

[0052] like Figure 2 As shown, side grooves 17 connected to the bottom groove 10 are provided at the lower ends of both sides of the connecting chassis 1, two groups of robot arm mounting seats 9 are symmetrically arranged on the top of the bracket 3, and visual protection windows 16 are fixedly connected to both sides of the bracket 3. The other two sides of the bracket 3 are open, and the monitoring camera 13 and the photoelectric switch 12 are electrically connected to the integrated controller 2. The robot arm can be conveniently installed through the mechanical handle mounting seat, and the robot arm with different functions can be replaced according to different splicing methods, which improves adaptability. The design of the visual protection window 16 is convenient for the operator to observe the assembly process while ensuring safety.

[0053] During specific use, the trusses to be assembled are placed on two groups of supporting mechanisms 6 respectively, and the alignment mechanism 5 is moved to the two sides of the connecting chassis 1 through the moving frame 4, and the alignment guide rod 21 is inserted into the alignment hole 19 to preliminarily position the alignment mechanism 5, and then the electromagnet 18 is energized to magnetically attract the positioning iron sheet to improve the stability of the alignment mechanism 5 located on both sides of the connecting chassis 1.

[0054] The first dual-axis motor 71 is controlled by the integrated controller 2 to drive the first screw 72, so that the first screw 72 drives the two groups of clamps 74 to be relatively close, so that the clamping plates 744 of the clamps 74 clamp and position the trusses, so that the two groups of trusses are located on the same axis for alignment and assembly.

[0055] The integrated controller 2 controls the first motor 54 to drive the pitch-adjusting screw 53 to rotate. The pitch-adjusting screw 53 drives the sliding seat 61 of the support mechanism 6 to move along the first guide beam 52 towards the connection chassis 1, so that the support mechanisms 6 on the two groups of alignment mechanisms 5 approach each other relatively. During the approaching process, the position of the truss is monitored by the photoelectric switch 12, and at the same time, the distance sensor 86 is used to monitor the distance between the buffer mechanism 8 and the baffle 14. When the pressure sensor 15 on one side of the baffle 14 detects pressure, it transmits a signal to the integrated controller 2 to control the first motor 54 to stop. At the same time, the integrated controller 2 controls the lifting cylinder 1111 to lift the polishing assembly 113 and start the second biaxial motor 1131.

[0056] After the second biaxial motor 1131 is started, the integrated controller 2 controls the first motor 54 to start again, so that the truss abuts against the polishing disc 1133 of the polishing assembly 113. The first pressure sensor 15 detects that the pressure increases again, and thus transmits a signal to the integrated controller 2 to control the first motor 54 to stop. The second motor 1121 drives the driving gear shaft 1122 to make the driven gear 1124 drive the reciprocating screw 1123 to adjust the position of the T-shaped plate 1125, so that the polishing disc 1133 polishes the end face of the truss, improving the flatness of the truss end face.

[0057] After polishing, the polishing mechanism is retracted into the bottom groove 10. The integrated controller 2 controls the first motor 54 to drive the support mechanism 6 to move the position of the truss again, so that the trusses abut against each other relatively. During the assembly process of the trusses, the buffer mechanism 8 can prevent the two groups of trusses from rigid contact, avoid damage to the truss end face, and improve the truss splicing effect.

[0058] According to different assembly requirements, a welding robotic arm or a bolt installation splicing arm is installed on the robotic arm mounting seat 9, so as to facilitate welding or bolt connection of the trusses, improve the efficiency of truss splicing. The monitoring camera 13 is used to monitor the truss assembly process in real time, so as to ensure the assembly accuracy and safety, speed up the work progress and improve the assembly effect of the device.

[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
