Description

Technical Field

[0001] The invention belongs to the technical field of embedded casing construction, and specifically relates to a processing device for embedded casing steel bar supports. Background Art

[0002] When preparing existing concrete precast components, it is necessary to make holes on the surface of the precast components for later installation and use. Currently, the method of making holes is to fix the embedded casing inside the precast component mold and then pour concrete. For the fixation of the embedded casing in the mold, currently, it is achieved by welding steel bar supports on the surface of the embedded casing. Specifically, steel bar supports are welded on the surface of the embedded casing, and the embedded casing is supported in the mold through the steel bar supports. When pouring concrete into the mold later, the embedded casing can be kept stable. To ensure the supporting effect of the steel bar supports on the embedded casing, the ends of the steel bar supports are usually bent and then welded, so that the L-shaped steel bar supports have good supporting stability for the embedded casing. Currently, the welding of steel bar supports and embedded casings by workers has low efficiency. When mass-producing precast components, it is difficult to weld a specified volume of embedded casings within a specified construction period. Therefore, it is necessary to improve the welding efficiency between the steel bar supports and the embedded casings.

[0003] Therefore, the invention provides a processing device for embedded casing steel bar supports. Summary of the Invention

A pair of driving rollers are arranged inside the feeding belt, and the ends of the driving rollers are provided with driving motors installed at the ends of the workbenches. A discharging belt is arranged between the pair of workbenches. A driving component is arranged inside the discharging belt. At the top of the workbench and on both sides of the feeding notch, there are a pair of fixing plates. A rotating belt is rotatably arranged on the side surface of the fixing plate. A plurality of rubber blocks are evenly arranged on the surface of the rotating belt, and the clamping surface of the rubber block is set to be an inward concave arc. A fixing frame is arranged at the top of the fixing plate, and a welding component is arranged at the top of the fixing frame. On the top of the workbench and on both sides of the feeding notch, a pair of lifting hydraulic cylinders are arranged. The output end of the lifting hydraulic cylinder is provided with a receiving frame. The top of the receiving frame is provided with a servo motor. The output end of the servo motor is provided with a driving gear. Between the pair of driving gears, a receiving ring is arranged. Inside the receiving ring, a pair of pushing devices are arranged. The output end of the pushing device is provided with a clamping plate; outside the receiving ring, an annular ring is sleeved. On the surface of the annular ring, an annular groove is formed; inside the annular groove, a toothed ring is arranged. The driving gear is inserted into the annular groove and meshes with the toothed ring; on the top of the workbench and on both sides of the pair of fixing plates, a pair of adjusting hydraulic cylinders are arranged. Between the output end of the adjusting hydraulic cylinder and the fixing plate, a connecting piece is arranged.

[0006] Preferably, on the top of the workbench and on both sides of the feeding end of the feeding belt, a pair of supporting plates are arranged. On the side surface of the supporting plate, a pair of return springs are arranged. The end of the return spring away from the supporting plate is provided with a limiting column. A plurality of the limiting columns are located directly above the feeding end of the feeding belt.

[0007] Preferably, between the limiting column and the feeding belt, a pair of limiting plates are arranged. Between the limiting plate and the supporting plate, a connecting frame is arranged; the distance between the pair of limiting plates is the same as the diameter of the steel bar to be welded; the top of the limiting plate is set to be inclined towards the connecting frame.

[0008] Preferably, on the top of the rubber block, a guiding plate is arranged. The top of the guiding plate is set to be inclined towards the fixing plate.

[0009] Preferably, the feeding belt includes a pair of first belts and a second belt; the second belt is located between the pair of first belts; both the first belt and the second belt are sleeved on the surface of the driving roller; On the inner surface of the first belt, a plurality of receiving strips are uniformly arranged; on one end of the receiving strip facing the second belt, a plugging groove is formed; inside the plugging groove, a rubber strip is plugged; between the rubber strip and the plugging groove, a tension spring is arranged; inside the rubber strip, a plurality of magnetic blocks are arranged; at the bottom of the workbench and on both sides of the second belt, a pair of magnetic plates with magnetic poles opposite to those of the magnetic blocks are arranged; when the rubber strip is at the lowest position, the magnetic blocks and the magnetic plates reach the magnetic attraction distance. The discharging belt includes a pair of third belts and a fourth belt; the fourth belt is located between the pair of third belts; At the bottom of the workbench and directly below the second belt, a sliding plate is arranged. Above the sliding plate, a control hydraulic cylinder installed at the bottom of the workbench is arranged. The output end of the control hydraulic cylinder is connected to the sliding plate.

[0010] The beneficial effects of the present invention are as follows: 1. By setting up a loading belt and an unloading belt; during use, the steel bar bracket is automatically driven by the loading belt to contact the embedded casing; then welding is completed by a welding component; finally, it is transferred by the unloading belt. The above welding process has the advantages of high automation and high welding efficiency, which is conducive to batch welding operations during the construction period.

[0011] 2. By setting up a limiting plate; when loading the steel bar bracket onto the loading belt, the bent part of the steel bar bracket will pass between a pair of limiting plates. Since the distance between the pair of limiting plates is the same as the diameter of the steel bar to be welded; therefore, only when the bent part of the steel bar bracket is directly facing the embedded casing can it move down smoothly. Therefore, during the loading process of the steel bar bracket, the end of the bent part is necessarily restricted to point to the embedded casing, ensuring the accuracy of the welding position later.

DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0016] like Figures 1 to 9 As shown, a pre-buried sleeve steel bar support processing device according to an embodiment of the present invention comprises a pair of workbenches 1, a feeding notch 11 is provided at one end of the pair of workbenches 1 which is away from each other, a feeding belt 12 is installed inside the feeding notch 11, a pair of driving rollers 123 are arranged inside the feeding belt 12, and a driving motor installed at the end of the workbench 1 is arranged at the end of the driving roller 123; A material unloading belt 2 is arranged between a pair of workbenches 1; a driving assembly is arranged inside the material unloading belt 2; a pair of fixed plates 4 are arranged at the top of the workbench 1 and on both sides of the material loading notch 11, a rotating belt 41 is rotatably arranged on the side of the fixed plate 4, a plurality of rubber blocks 42 are evenly arranged on the surface of the rotating belt 41, and the clamping surface of the rubber block 42 is arranged in an inward concave arc shape; a fixing frame 40 is arranged at the top of the fixing plate 4, and a welding assembly 401 is arranged at the top of the fixing frame 40; A pair of lifting hydraulic cylinders 3 are arranged at the top of the workbench 1 and on both sides of the feeding gap 11, a receiving frame 31 is arranged at the output end of the lifting hydraulic cylinder 3, a servo motor 32 is arranged at the top of the receiving frame 31, a driving gear 33 is arranged at the output end of the servo motor 32, a receiving ring 6 is arranged between the pair of driving gears 33, a pair of ejectors 63 are arranged on the inner side of the receiving ring 6, and a clamping plate 64 is arranged at the output end of the ejector 63; an annular ring 61 is sleeved on the outer side of the receiving ring 6, and an annular groove is opened on the surface of the annular ring 61; a gear ring 62 is arranged inside the annular groove, and the driving gear 33 is inserted into the inside of the annular groove and meshes with the gear ring 62; a pair of adjusting hydraulic cylinders 5 are arranged at the top of the workbench 1 and on both sides of a pair of fixed plates 4, and a connecting piece 51 is arranged between the output end of the adjusting hydraulic cylinder 5 and the fixed plate 4; Currently, in the welding operation of steel bar supports and embedded sleeves, the welding efficiency is relatively low. When mass-producing prefabricated components, it is difficult to weld a specified volume of embedded sleeves within the specified construction period. Therefore, it is necessary to improve the welding efficiency between the steel bar supports and the embedded sleeves. To solve the above problems, the embodiment of the present invention is provided with a feeding belt 12, a discharging belt 2 and other structures. The specific usage process is as follows: When in use, the staff first bends the end of the steel bar support with a specified length through a bending device, and then inserts the bent steel bar support between a pair of fixing plates 4. The insertion process can be carried out by clamping and transferring with a manipulator. And the inserted steel bar support is located at the feeding end of the feeding belt 12. When feeding, the bottom end of the steel bar support passes through a pair of rubber blocks 42, and the arc-shaped concave surface of the rubber blocks 42 clamps and fixes the steel bar support, so that the steel bar support is kept stable. Then the driving motor is started. The driving motor drives the driving roller 123 to rotate, the driving roller 123 drives the feeding belt 12 to rotate, and the feeding belt 12 drives the steel bar support to move through the friction with the bottom end of the steel bar support. When the steel bar support moves, it drives the rotating belt 41 to rotate around the fixing plate 4 through the rubber blocks 42. At the same time, the embedded sleeve is fed onto the discharging belt 2 by a manipulator, and then the driving component of the discharging belt 2 is started, and the discharging belt 2 drives the embedded sleeve to move to the welding station, that is, the position between a pair of workbenches 1. It should be noted that when the embedded sleeve moves to the welding station, the receiving ring 6 is located above the embedded sleeve. Then, the lifting hydraulic cylinder 3, the receiving frame 31, the driving gear 33 and the annular ring 61 drive the receiving ring 6 to move downward. At this time, the center line of the receiving ring 6 coincides with the center line of the embedded sleeve. Stop when the receiving ring 6 is moved below the top end of the embedded sleeve. Then, the top pusher 63 is used to control the clamping plate 64 to press against the side of the embedded sleeve to fix the embedded sleeve. The feeding belt 12 controls the bent end of the steel bar support to move until it contacts the embedded sleeve and then stops. At this time, the steel bar support is fed again on the feeding belt 12. At the same time, the welding component 401 on the fixing frame 40 welds and fixes the connection between the steel bar support and the embedded sleeve. The specific welding method is fusion welding. When the welding is completed, the adjusting hydraulic cylinder 5 and the connecting piece 51 drive the fixing plate 4 to move away from the embedded sleeve, and the steel bar support between the pair of rubber blocks 42 is disengaged. Then, the servo motor 32 drives the toothed ring 62 to rotate through the driving gear 33. The toothed ring 62 drives the embedded sleeve to rotate by 90 degrees through the annular ring 61, the receiving ring 6, the top pusher 63 and the clamping plate 64. The embedded sleeve drives the steel bar support to rotate to the surface of the discharging belt 2. Then the position of the fixing plate 4 is restored. Repeat the above welding process. After welding two pairs of steel bar supports on the surface of the embedded sleeve, move the fixing plate 4 away from the embedded sleeve again. Then, the discharging belt 2 is used to move the embedded sleeve to the discharging end, and the manipulator is used for discharging. The above welding process has the advantages of high automation degree and high welding efficiency, which is beneficial to mass welding operations within the construction period.

[0017] A pair of support plates 7 are provided at the top of the workbench 1 and on both sides of the feeding end of the feeding belt 12, a pair of return springs 71 are provided on the sides of the support plates 7, and a limiting column 72 is provided at the end of the return spring 71 away from the support plate 7, and a plurality of limiting columns 72 are located directly above the feeding end of the feeding belt 12; when the steel bar bracket is loaded onto the feeding belt 12 by the robot, the vertical part of the steel bar is embedded between the two pairs of limiting columns 72, and then the two pairs of limiting columns 72 will limit the vertical downward movement of the steel bar bracket, and then accurately insert it between the pair of rubber blocks 42 below, so as to facilitate the positioning operation of the robot during initial loading.

[0018] A pair of limiting plates 74 are provided between the limiting columns 72 and the feeding belt 12, and a connecting frame 73 is provided between the limiting plates 74 and the supporting plate 7; the spacing between the limiting plates 74 is the same as the diameter of the steel bar to be welded; the top end of the limiting plate 74 is arranged to be inclined in the direction of the connecting frame 73; when the steel bar support is fed onto the feeding belt 12, the bent portion of the steel bar support will pass between the pair of limiting plates 74, because the spacing between the pair of limiting plates 74 is the same as the diameter of the steel bar to be welded; therefore, the bent portion of the steel bar support can only move downward smoothly if it is facing the embedded sleeve. Therefore, during the feeding process of the steel bar support, the end of the bent portion must be restricted to point to the embedded sleeve to ensure the accuracy of the subsequent welding position.

[0019] A guide plate 43 is provided at the top of the rubber block 42, and the top of the guide plate 43 is set to be inclined in the direction of the fixed plate 4; for steel bars with different diameters, when the steel bars are loaded, the bottom end of the steel bars will be guided by the inclined part of the guide plate 43, and then as the steel bars move downward, the guide plate 43 can guide the bottom end of the steel bars to between a pair of rubber blocks 42; the rubber block 42 will deform accordingly during the guidance, so that the welding of steel bars with different sizes is convenient.

[0020] The upper material belt 12 includes a pair of first material belts 121 and a second material belt 122; the second material belt 122 is located between the pair of first material belts 121; the first material belt 121 and the second material belt 122 are both sleeved on the surface of the driving roller 123; A plurality of receiving strips 124 are evenly arranged on the inner surface of the first material strip 121; a plug-in slot 1241 is provided at one end of the receiving strip 124 facing the second material strip 122; a rubber strip 1242 is plugged into the plug-in slot 1241; a tension spring 1243 is arranged between the rubber strip 1242 and the plug-in slot 1241; a plurality of magnetic blocks are arranged inside the rubber strip 1242; a pair of magnetic plates 125 with different magnetic properties from the magnetic blocks are arranged at the bottom end of the workbench 1 and on both sides of the second material strip 122; when the rubber strip 1242 is at the bottom, the magnetic blocks and the magnetic plates 125 reach a magnetic attraction distance; The lower material belt 2 includes a pair of third material belts 20 and a fourth material belt 21; the fourth material belt 21 is located between the pair of third material belts 20; A slide plate 14 is provided at the bottom of the workbench 1 and directly below the second material belt 122. A control hydraulic cylinder 13 installed at the bottom of the workbench 1 is provided above the slide plate 14. The output end of the control hydraulic cylinder 13 is connected to the slide plate 14. There is a welding situation: the bottom end of the steel bar support is lower than the bottom end of the embedded sleeve; so that the embedded sleeve is supported to the top of the mold; to meet the use requirements; therefore, the first material strip 121, the second material strip 122 and other structures are set; when the bottom end of the weld is lower than the steel bars of the embedded sleeve; the second material strip 122 is removed; there is a gap between a pair of first material strips 121; the bottom end of the steel bar support can pass through the gap and be supported by the slide plate 14; the height of the slide plate 14 can be adjusted by controlling the hydraulic cylinder 13; then, with the rotation of the first material strip 121, the support strip 124 rotates synchronously, because when the rubber strip 1242 is at the bottom, the magnetic block and the magnetic plate 125 reach the magnetic attraction distance; therefore, the bottom The rubber strip 1242 compresses the tension spring 1243 under the action of magnetic force and retracts into the insertion slot 1241; the magnetic block in the uppermost rubber strip 1242 is not affected by the magnetic force; under the action of the elastic force of the tension spring 1243, it is reset to contact with the steel support in the gap, thereby driving the steel support to move in the direction close to the embedded sleeve; it should be pointed out that the rubber strip 1242 can be deformed to a certain extent to avoid interfering with the movement of the steel support when the steel support is loaded; and the bottom end of the steel support slides on the slide plate 14; the surface of the slide plate 14 is polished; therefore, the friction resistance of the steel support is small; the steel support can be driven to move by the rubber strip 1242; When the initial welding between the steel bar support and the embedded sleeve is completed, the fourth material strip 21 is removed, and then the embedded sleeve is controlled to move upward by structures such as the clamping plate 64, so as to drive the bottom end of the steel bar support to move above the workbench 1; then the fixed plate 4 is moved; the restriction of the steel bar support by a pair of rubber blocks 42 is released; then the embedded sleeve is rotated so that the steel bar support is located above the gap between the pair of third material strips 20; then the embedded sleeve is moved downward so that a pair of steel bar supports are inserted into the gap between the pair of third material strips 20; when the embedded sleeve is restored to the welding position, it is stopped, and then the welding operation is repeated; when the welding is completed, there are two pairs of steel bar supports on the surface of the embedded sleeve, so it is necessary to transfer and unload the welded embedded sleeve by a manipulator; when unloading, the receiving frame 31 needs to be moved to the top of the embedded sleeve to prevent the structure on the receiving frame 31 from interfering with the unloading of the embedded sleeve and the steel bar support welded on the surface; It should be pointed out that the above process can be completed through automatic control by a microcomputer; manpower is saved; multiple workers do not need to cooperate with each other during welding; the welding of the fixed steel bar bracket and the embedded casing is completed at the same time; and after the program is set, the device can work continuously with high production efficiency.
