Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a hot-melt splicing device for threaded steel bars used in building construction. Background Technology

[0002] With the development of the construction industry, reinforced concrete structures have greatly improved the stability of buildings. Reinforced concrete structures are composite structures made of steel bars and concrete. The main load-bearing components work together by having the steel bars bear the tensile force and the concrete bear the compressive force, which has the advantages of strong durability and good fire resistance.

[0003] Currently, when using rebar, if the length is insufficient, it is necessary to perform hot-melt splicing. However, when using existing equipment for hot-melt splicing, the positioning mechanism needs to be adjusted when positioning and gripping rebar of different lengths, resulting in very low hot-melt efficiency. At the same time, inaccurate positioning can easily occur during positioning, affecting the quality of hot-melt splicing.

[0004] Based on this, the present invention designs a hot-melt splicing device for threaded steel bars used in building construction to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a hot-melt splicing device for threaded steel bars used in building construction, which aims to solve the technical problems existing in the prior art mentioned in the background.

[0007] Furthermore, the fixing mechanism includes multiple rotary cylinders mounted on the mounting platform. The output end of each rotary cylinder passes through the V-shaped positioning plate and is slidably connected to the V-shaped positioning plate. A fixing rubber block is fixedly installed on the output end of the rotary cylinder.

[0008] Furthermore, the moving mechanism includes a moving motor fixedly mounted on the mounting platform, a rotating lead screw fixedly mounted at the output end of the moving motor, the rotating lead screw and two lead screw sliders forming a helical pair transmission in opposite directions, each lead screw slider being slidably connected to the mounting platform, a moving block being fixedly mounted on the surface of the lead screw slider, and a rotating shaft mounted on the mounting platform corresponding to the moving block, the rotating shaft being rotatably connected to the pulling mechanism, a support block being fixedly mounted on the surface of the rotating shaft, a V-shaped positioning plate and a rotary cylinder being fixedly mounted on the surface of the support block, and a damper being provided on the rotating shaft.

[0009] Furthermore, the rotating mechanism includes two rotating gears mounted on the mounting platform, each rotating gear having a rotating shaft fixedly mounted on its surface, and also includes a fixed rack fixedly mounted on the mounting platform that cooperates with the rotating gears.

[0010] Furthermore, the pulling mechanism includes a fixed circular plate fixedly connected to the inner wall of the moving block. The inner wall of the fixed circular plate is rotatably connected to the rotating shaft. A straight groove that mates with the fixed circular plate is provided on the mounting platform. An eccentric groove and a concentric groove are sequentially and smoothly connected on the surface of the fixed circular plate. The trajectory of the eccentric groove gradually moves away from the central axis of the fixed circular plate, while the trajectory of the concentric groove is equidistant from the central axis of the fixed circular plate. A T-shaped connecting rod passes through the interior of the support block and is slidably connected to the T-shaped connecting rod. A groove that mates with the eccentric groove is fixedly installed on the surface of the T-shaped connecting rod. The linkage slide rod, which cooperates with the concentric groove, has a connecting plate fixedly installed at the end of the T-shaped connecting rod away from the linkage slide rod. Two movable racks are fixedly installed on the surface of the connecting plate, and each movable rack meshes with a stop gear. The two stop gears share a connecting shaft, which passes through the V-shaped slide plate and is rotatably connected to the V-shaped slide plate. An arc-shaped baffle concentric with the connecting shaft is fixedly installed on the surface of the V-shaped slide plate, and a positioning baffle is fixedly installed on the connecting shaft. The V-shaped slide plate is slidably connected to the V-shaped positioning plate, and the V-shaped slide plate is connected to the support block through a compression spring.

[0011] Furthermore, the limiting mechanism includes two stepped plates fixedly installed on the connecting plate, and a fixed frame corresponding to the stepped plates fixedly installed on the V-shaped positioning plate. A concave slider is slidably installed on the inner wall of the fixed frame, and a rolling ball cooperating with the stepped plate is rotatably installed on the surface of the concave slider. The concave slider and the fixed frame are connected by a return spring.

[0012] Furthermore, the positioning baffle is made of hard rubber.

After the threaded steel bars are contacted and connected, the hot melt machine is driven by external equipment to move to the contact position of the threaded steel bars for hot melting, thereby achieving the purpose of automatically and accurately positioning and hot melting threaded steel bars of different lengths.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0019] like Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, in one embodiment, a hot-melt splicing device for threaded steel bars used in building construction is provided, the device comprising: Main frame 1: It is equipped with a mounting platform 101; Positioning mechanism 2 includes two inclined and symmetrical V-shaped positioning plates 201 installed on the mounting platform 101 for supporting the threaded steel bars, and a positioning baffle 202 installed on the mounting platform 101 for blocking the threaded steel bars and corresponding to each V-shaped positioning plate 201. Fixing mechanism 3: Used to fix the threaded steel bars; Moving mechanism 4: used to drive the V-shaped positioning plate 201 to move horizontally; Rotating mechanism 5: used to drive the V-shaped positioning plate 201 to rotate; Pulling mechanism 6: In cooperation with limiting mechanism 7, it drives positioning baffle 202 to rotate and then move horizontally relative to V-shaped positioning plate 201.

[0020] In practical applications, when hot-melt welding of rebar is required, such as... Figure 1 As shown, the two threaded steel bars are then placed on the V-shaped positioning plate 201, as follows. Figure 3 As shown, under the action of gravity, the rebar slides down to one end and rests against the positioning baffle 202. At this time, the rebar is fixed by the operation of the fixing mechanism 3, thereby achieving the purpose of automatically positioning and fixing the hot-melt end of the rebar. After the rebar is fixed, as shown... Figure 5 As shown, at this time, the moving mechanism 4 drives the two V-shaped positioning plates 201 to move towards each other, and the rotating mechanism 5 causes the threaded steel on the symmetrical V-shaped positioning plates 201 to rotate, as shown. Figure 3 , Figure 9 and Figure 10 As shown, during the rotation process, the positioning baffle 202 rotates and moves towards the other end of the rebar through the combined action of the pulling mechanism 6 and the limiting mechanism 7, thereby exposing the hot-melt end of the rebar. Figure 6 and Figure 8 As shown, the rotating mechanism 5 rotates the threaded steel bars on the V-shaped positioning plates 201 at both ends to a horizontal state. Then, the moving mechanism 4 drives the two threaded steel bars to contact each other. After the threaded steel bars are contacted and connected, the external equipment drives the hot melt machine to move to the contact position of the threaded steel bars for hot melting, thereby achieving the purpose of automatically and accurately positioning and hot melting threaded steel bars of different lengths. After the hot melt connection is completed, the resetting of the fixing mechanism 3 and the movement of the external gripping equipment complete the unloading operation of the threaded steel bars after the hot melt connection.

[0021] like Figure 2 As shown, in a preferred embodiment of the present invention, the fixing mechanism 3 includes a plurality of rotary cylinders 301 mounted on the mounting platform 101. The output end of each rotary cylinder 301 passes through the V-shaped positioning plate 201 and is slidably connected to the V-shaped positioning plate 201. A fixing rubber block 302 is fixedly mounted on the output end of the rotary cylinder 301.

[0022] In practical applications, after the rebar is fed into the container, as shown in the embodiments of the present invention... Figure 2 As shown, at this time, the rotary cylinder 301 starts to operate. The operation of the rotary cylinder 301 drives the fixed rubber block 302 to rotate above the threaded steel and press down, thereby achieving the purpose of automatically fixing the threaded steel.

[0023] like Figure 4 and Figure 5As shown, in another preferred embodiment of the present invention, the moving mechanism 4 includes a moving motor 401 fixedly mounted on the mounting platform 101. A rotating lead screw 402 is fixedly mounted on the output end of the moving motor 401. The rotating lead screw 402 and two lead screw sliders 403 form a helical pair transmission in opposite directions. Each lead screw slider 403 is slidably connected to the mounting platform 101. A moving block 404 is fixedly mounted on the surface of the lead screw slider 403. The mechanism also includes a rotating shaft 405 mounted on the mounting platform 101 corresponding to the moving block 404. The rotating shaft 405 is rotatably connected to the pulling mechanism 6. A support block 406 is fixedly mounted on the surface of the rotating shaft 405. A V-shaped positioning plate 201 and a rotary cylinder 301 are fixedly mounted on the surface of the support block 406. A damper is provided on the rotating shaft 405.

[0024] In practical applications, after the threaded steel bars are fixed, as in the embodiments of the present invention... Figure 5 As shown, the moving motor 401 starts running at this time. The operation of the moving motor 401 drives the rotating screw 402 to rotate, which in turn drives the screw slider 403 to move towards each other through two opposite helical pairs. The movement of the screw slider 403 drives the two symmetrical V-shaped positioning plates 201 to move towards each other through the moving block 404, the rotating shaft 405 and the support block 406, thereby driving the two threaded steel bars to move closer to each other.

[0025] like Figure 6 , Figure 7 and Figure 8 As shown, in another preferred embodiment of the present invention, the rotating mechanism 5 includes two rotating gears 501 mounted on the mounting platform 101, each rotating gear 501 having a rotating shaft 405 fixedly mounted on its surface, and also includes a fixed rack 502 fixedly mounted on the mounting platform 101 and cooperating with the rotating gears 501.

[0026] In practical application, when the threaded steel bars move horizontally, the rotating gear 501 rotates through the cooperation of the rotating gear 501 and the fixed rack 502. Then, the rotating shaft 405 drives the support block 406 to rotate. The rotation of the support block 406 drives the V-shaped positioning plate 201 to rotate to a horizontal state, thereby enabling the two threaded steel bars to be connected under the action of the moving mechanism 4.

[0027] like Figure 9 and Figure 11As shown, in another preferred embodiment of the present invention, the pulling mechanism 6 includes a fixed circular plate 601 fixedly connected to the inner wall of the moving block 404. The inner wall of the fixed circular plate 601 is rotatably connected to the rotating shaft 405. A straight sliding groove that cooperates with the fixed circular plate 601 is provided on the mounting platform 101. An eccentric groove 602 and a concentric groove 603 are sequentially and smoothly connected on the surface of the fixed circular plate 601. The trajectory of the eccentric groove 602 gradually moves away from the central axis of the fixed circular plate 601, and the trajectory of the concentric groove 603 is equidistant from the central axis of the fixed circular plate 601. A T-shaped connecting rod 605 passes through the interior of the support block 406 and is slidably connected to the T-shaped connecting rod 605. A groove that cooperates with the eccentric groove is fixedly installed on the surface of the T-shaped connecting rod 605. A linkage slide rod 604, which cooperates with concentric groove 603, is connected to a T-shaped connecting rod 605. A connecting plate 606 is fixedly installed at the end of the T-shaped connecting rod 605 away from the linkage slide rod 604. Two movable racks 607 are fixedly installed on the surface of the connecting plate 606. Each movable rack 607 meshes with a stop gear 608. The two stop gears 608 share a connecting shaft. The connecting shaft passes through the V-shaped slide plate 611 and is rotatably connected to the V-shaped slide plate 611. An arc-shaped baffle 610 concentric with the connecting shaft is fixedly installed on the surface of the V-shaped slide plate 611. A positioning baffle 202 is fixedly installed on the connecting shaft. The V-shaped slide plate 611 is slidably connected to the V-shaped positioning plate 201. The V-shaped slide plate 611 is connected to the support block 406 through a compression spring 609.

[0028] In practical applications, when the V-shaped positioning plate 201 is rotated by the rotating mechanism 5, as shown in the embodiments of the present invention... Figure 9 As shown, at this time, the T-shaped connecting rod 605 moves away from the contact end between the positioning baffle 202 and the threaded steel through the cooperation of the linkage slide rod 604 and the eccentric groove 602. Then, through the connecting plate 606 and the moving rack 607, it moves away from the contact end between the positioning baffle 202 and the threaded steel. The meshing of the moving rack 607 and the stop gear 608 drives the stop gear 608 to rotate. Figure 11 As shown, this allows the positioning baffle 202 to disengage from the rebar without affecting its position. When the positioning baffle 202 rotates 180 degrees, the V-shaped sliding plate 611 disengages from the limiting mechanism 7 and is restricted from rotating by the arc-shaped baffle 610. At this time, the moving rack 607 drives the positioning baffle 202 to move linearly relative to the V-shaped positioning plate 201 through the stop gear 608, exposing the hot-melt end of the rebar, thus facilitating the butt welding of the rebar.

[0029] like Figure 9 and Figure 10As shown, in another preferred embodiment of the present invention, the limiting mechanism 7 includes two stepped plates 701 fixedly installed on the connecting plate 606, and a fixed frame 705 corresponding to the stepped plates 701 fixedly installed on the V-shaped positioning plate 201. A concave slider 703 is slidably installed on the inner wall of the fixed frame 705. A rolling ball 702 cooperating with the stepped plates 701 is rotatably installed on the surface of the concave slider 703. The concave slider 703 and the fixed frame 705 are connected by a return spring 704.

[0030] In practical applications, the embodiments of the present invention, such as Figure 9 and Figure 10 As shown, when the connecting plate 606 moves linearly relative to the V-shaped positioning plate 201, the connecting plate 606 drives the stepped plate 701 to move linearly relative to the V-shaped positioning plate 201. Through the stepped structure of the stepped plate 701 and the cooperation of the rolling ball 702, the concave slider 703 moves into the interior of the fixed frame 705. When the positioning baffle 202 is blocked by the arc baffle 610, the concave slider 703 no longer blocks the V-shaped sliding plate 611. Through the engagement of the moving rack 607 with the stop gear 608, the V-shaped sliding plate 611 moves linearly, thereby exposing the hot melt end of the rebar, which is convenient for subsequent docking.

[0031] like Figure 11 As shown, in another preferred embodiment of the present invention, the positioning baffle 202 is made of hard rubber.

[0032] In practical applications, the embodiments of the present invention, such as Figure 11 As shown, by setting the positioning baffle 202 to a hard rubber material, the elastic recovery of the positioning baffle 202 is increased, avoiding positioning errors caused by deformation.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
