Description

Technical Field

[0001] The invention relates to the technical field of scaffold component drilling processing, in particular to scaffold component processing equipment for house construction. Background Art

[0002] Scaffolding is a temporary structure used to support workers, materials and equipment in housing construction. Pan scaffolding is a common scaffolding for housing construction. It has the advantages of less structure, easy assembly and disassembly, and large load-bearing capacity. Fig.15 As shown, the disc scaffolding is mainly composed of metal pipes and discs. The main load-bearing of the disc scaffolding is borne by the metal pipes. Both ends of the metal pipes are provided with connecting holes for connecting with metal pipes of other disc scaffoldings during construction. The discs are evenly welded to the outside of the metal pipes. There are usually 8 holes on the discs for connecting crossbars during construction.

[0003] For drilling holes in metal tubes of disc-type scaffolding, the utility model patent with patent number CN216441677U discloses a fast drilling tool for disc-type scaffolding uprights. The scaffolding uprights (i.e., metal tubes) are drilled by an automatic drilling tool. Two sets of drilling equipment on the tool drill holes in the uprights alternately, so that the tool can work without stopping, thereby realizing continuous drilling.

[0004] The above technical solution has the following problems when drilling: 1. Since the metal tube of the disc-type scaffolding is a hollow structure, the metal tube may be deformed when drilling the metal tube, which will lead to a decrease in the bearing capacity of the disc-type scaffolding during later use; 2. After the metal tube of the disc-type scaffolding is drilled, burrs usually remain at the drilled holes on the inner wall of the metal tube, resulting in an uneven surface at the connection of the metal tube. When the disc-type scaffolding is erected, the connection between the metal tube of the disc-type scaffolding and the metal tube of the adjacent disc-type scaffolding cannot fit tightly, which will cause the scaffolding to become loose or unstable during use; 3. Since the metal tube of the disc-type scaffolding is a cylindrical structure, when the drill bit instantly contacts the metal tube, the metal tube may rotate, causing the position of the drill hole to shift.

[0040] It should be noted that the drilling device 2 adopts the existing technology, which is mainly composed of a hydraulic rod, a control unit and a drill bit, wherein the hydraulic rod is installed on the rear side of the middle of the upper end of the workbench 1, the control unit is installed on the upper end of the hydraulic rod, and the drill bit is installed on the front side of the lower end of the control unit.

[0041] The present invention can accurately drill holes in metal tubes of disc-type scaffolding, and can support the inner wall of the metal tube when drilling holes in the metal tube, thereby preventing the metal tube from being deformed; specifically, firstly, the position of the adjusting device 5 is adjusted according to the distance between the drilling position and the disc of the disc-type scaffolding, and then the metal tube of the disc-type scaffolding is placed in the clamping device 4, and the drilling position is directed upward, the clamping device 4 is controlled to pre-clamp the metal tube of the disc-type scaffolding, and then the adjusting device 5 is controlled to clamp the discs adjacent to the drilling position of the metal tube of the disc-type scaffolding, and then the clamping device 4 is controlled to completely clamp the metal tube of the disc-type scaffolding, and after the complete clamping is completed, the supporting device 3 is controlled to extend into the metal tube of the disc-type scaffolding, so that the supporting device 3 can support the inner wall of the metal tube, and finally the drilling device 2 is started to complete the drilling operation of the disc-type scaffolding.

[0042] See also Figure 1 and Figure 2 The clamping device 4 includes two synchronous plates 41 symmetrically arranged front and back and mounted on the upper end of the workbench 1 for forward and backward sliding. The two synchronous plates 41 are jointly installed with a bidirectional screw 42 by threaded cooperation, and the bidirectional screw 42 is rotatably connected to the workbench 1. The upper end of the synchronous plate 41 is fixedly installed with two locking sleeves 44 symmetrically arranged left and right through a support plate 43.

[0043] The clamping device 4 is used to stably clamp the two sides of the metal pipe punching position of the disc scaffolding; specifically, by screwing the bidirectional screw 42, the two synchronous plates 41 are driven to move towards each other, so that the synchronous plate 41 drives the locking sleeve 44 to stably clamp the metal pipe through the support plate 43, and the pre-clamping and complete clamping of the metal pipe of the disc scaffolding can be achieved by controlling the distance between the two locking sleeves 44 arranged front and back.

[0044] See also Figure 2 The adjusting device 5 includes an L-shaped adjusting plate 51 slidably mounted on the workbench 1, and a tightening unit 55 for preventing the metal tube from rotating is installed at both the front and rear ends of the adjusting plate 51. The adjusting plate 51 is installed with an adjusting screw 52 by threaded fitting, and the adjusting screw 52 is rotatably connected to the workbench 1. A clamping plate 53 is slidably mounted on the lateral section of the adjusting plate 51, and an active part 54 for driving the clamping plate 53 to move leftward is installed on the clamping plate 53 and the adjusting plate 51.

[0045] It should be noted that the active part 54 in the present invention includes a threaded screw connected to the clamping plate 53 by threaded cooperation, the left end of the threaded screw is rotationally connected to the vertical section of the adjustment plate 51, and the right end of the threaded screw is connected to the output shaft of the motor fixedly mounted on the horizontal section of the adjustment plate 51.

[0046] The adjusting device 5 can accurately adjust the position of the disc scaffolding metal tube, so that the drilling device 2 can accurately drill holes in the disc scaffolding metal tube; specifically, the adjusting screw 52 is screwed to drive the adjusting plate 51 to move left and right, so that the lateral distance between the vertical section of the adjusting plate 51 and the drill bit is the same as the drilling position of the disc scaffolding metal tube and the distance between its adjacent disks, and the disc of the disc scaffolding is placed between the vertical section of the adjusting plate 51 and the clamping plate 53, and the active member 54 is controlled to drive the clamping plate 53 to move left, so that the clamping plate 53 and the vertical section of the adjusting plate 51 cooperate to clamp the disc, and the clamping unit 55 is controlled to clamp the front and rear ends of the disc scaffolding to prevent the disc scaffolding metal tube from rotating during drilling, so that the drilling device 2 can perform accurate drilling.

[0047] See also Figure 2-Figure 5L-shaped rods 511 are symmetrically installed at the front and rear ends of the transverse section of the adjustment plate 51. The tightening unit 55 includes a square plate 551 fixedly installed at the left end of the transverse section of the L-shaped rod 511, and the square plate 551 is connected to the workbench 1 for sliding left and right. An electric telescopic rod 552 is installed on the right side of the upper end of the square plate 551, and a lifting member 553 is installed on the upper end of the electric telescopic rod 552. A stretching member 555 is installed at one end of the lifting member 553 close to the middle of the workbench 1 for sliding back and forth through a guide spring 554. A connecting block 557 is installed at one end of the stretching member 555 away from the lifting member 553 for sliding up and down through a buffer spring 556. The connecting block 557 is provided with a tightening rod 558 that slides through the left and right ends of the connecting block 557.

[0048] A guide frame 559 is installed on the left side of the upper end of the square plate 551, and the front and rear side walls of the guide frame 559 are provided with an inclined groove 550 with the right end tilted upward. An L-shaped guide rod 56 is fixedly installed on the left end of the clamping rod 558, and the end of the guide rod 56 close to the clamping rod 558 is set as an elastic telescopic structure, and the lower end of the vertical section of the guide rod 56 is slidably installed in the inclined groove 550.

[0049] The pressing unit 55 is used to press against the upper ends of the inner walls of two holes adjacent to each other on the disc of the disc scaffolding and before and after the drilling position to prevent the disc scaffolding from rotating when subjected to instantaneous force, thereby causing inaccurate drilling position.

[0050] Specifically, when the position of the adjustment plate 51 is adjusted, the adjustment plate 51 drives the square plate 551 to move synchronously through the L-shaped rod 511. When the position adjustment of the adjustment plate 51 is completed, the electric telescopic rod 552 is controlled to push the lifting member 553 upward, and the lifting member 553 finally drives the clamping rod 558 to move upward through the stretching member 555. At the same time, the clamping rod 558 drives the guide rod 56 to move upward along the inclined groove 550, and the guide rod 56 can drive the clamping rod 558 to move rightward under the action of the inclined groove 550, so that the clamping rod 558 can be extended into the hole adjacent to the drilling position on the corresponding disc-type scaffolding disc, and at the same time, the clamping rod 558 can move upward to press against the upper inner wall of the disc hole, and the upper inner wall of the disc hole is an arc-shaped structure, so that the clamping rod 558 can press against the upper ends of the inner walls of the two holes adjacent to the drilling position on the disc-type scaffolding disc and close to each other.

[0051] See also Figure 3 and Figure 5, a clamping rod 571 is installed on the left end of the stretching member 555 away from the lifting member 553 through the pressing spring 57 to slide left and right, a clamping hole for cooperating with the clamping rod 571 to lock the connecting block 557 is provided at the left end of the connecting block 557, an L-shaped plug-in rod 572 is installed at the left end of the clamping rod 571, and the end of the plug-in rod 572 close to the clamping rod 571 is set as an elastic telescopic structure, the right end of the transverse section of the plug-in rod 572 slides through the left end of the lifting member 553, and a plurality of plug-in grooves for cooperating with the transverse section of the plug-in rod 572 to lock the stretching member 555 are evenly opened on the stretching member 555. It should be noted that the clamping hole of the connecting block 557 is initially located above the clamping rod 571, and at this time the clamping rod 571 is against the left side of the connecting block 557 and makes the pressing spring 57 in a compressed state.

[0052] When the clamping rod 558 moves to a position where the upper ends of the inner walls of the two holes adjacent to the drilling position on the disc of the disc-type scaffolding are close to each other, the clamping rod 558 cannot continue to move, so that the clamping rod 558 compresses the buffer spring 556 through the connecting block 557. When the clamping hole of the connecting block 557 moves to the corresponding position of the clamping rod 571, the clamping rod 571 moves to the right under the action of the clamping spring 57 and is inserted into the clamping hole to lock the position of the connecting block 557. At the same time, the clamping rod 571 can drive the plug-in rod 572 to move to the right and insert the plug-in rod 572 into the plug-in slot of the corresponding tensile member 555, thereby locking the tensile member 555 and controlling the electric telescopic rod 552 to stop moving, so that the clamping rod 558 can be stably pressed against the position where the upper ends of the inner walls of the two holes adjacent to the drilling position on the disc of the disc-type scaffolding are close to each other.

[0053] After the drilling is completed, the clamping rod 571 is pulled out to the left and the electric telescopic rod 552 is controlled to move downward to the initial position. At the same time, the abutting rod 558 is restored to the initial position under the cooperation of the guide rod 56 and the inclined groove 550.

[0054] See also Figure 2 , Figure 6 and Fig.10 The supporting device 3 includes a back plate 31 fixedly mounted on the workbench 1, and a transmission rod 33 of an L-shaped structure is installed at the left end of the back plate 31 through an electric push rod 32, and a connecting plate 34 is installed on the right end of the transmission rod 33. The upper and lower ends of the connecting plate 34 are slidably installed with arc-shaped bonding plates 36 through a top spring rod 35. A rotating shaft 39 is rotatably installed at the right end of the connecting plate 34, and a grinding unit 37 for grinding the inner wall of the metal pipe is installed at the right end of the rotating shaft 39. A matching unit 38 for locking the top spring rod 35 and driving the rotating shaft 39 to reciprocate is installed on the back plate 31; the right ends of the two bonding plates 36 are provided with inclined surfaces on the sides away from each other, and a square hole running through the upper and lower ends is provided on the upper bonding plate 36.

[0055] The supporting device 3 is used to support the inner wall of the metal tube of the disc scaffolding to prevent the metal tube from being deformed during drilling; specifically, the electric push rod 32 is started and finally drives the square hole of the upper bonding plate 36 to move to the drilling position of the metal tube through the transmission rod 33, and at the same time, the connecting plate 34 drives the grinding unit 37 to extend into the metal tube through the rotating shaft 39. When the bonding plate 36 moves to the left end of the metal tube, the inclined surface of the bonding plate 36 drives the bonding plate 36 to move downward under the pushing action of the metal tube. At the same time, the bonding plate 36 can always be bonded to the inner wall of the metal tube under the action of the top spring rod 35, and the matching unit 38 locks the top spring rod 35 to make the bonding plate 36 rigidly bonded to the inner wall of the metal tube. Two bonding plates 36 are provided to increase the supporting effect on the metal tube.

[0056] When the metal tube is drilled, the electric push rod 32 is controlled to drive the bonding plate 36 to return to the initial position through the transmission rod 33. At the same time, the connecting plate 34 drives the grinding unit 37 to grind the inner wall of the metal tube through the rotating shaft 39 to remove the burrs remaining after the metal tube is drilled.

[0057] See also Figure 6 , Fig.12 and Fig.13 The grinding unit 37 includes a square frame 371 fixedly mounted on the right end of the rotating shaft 39, a rotating plate 372 with its upper end tilted to the left is rotatably mounted between the left sides of the front and rear inner walls of the square frame 371, a scraper 374 is slidably mounted on the upper end of the rotating plate 372 through a fitting spring 373, and the upper end of the scraper 374 is an arc-shaped structure, a top extension rod 375 of an elastic telescopic structure is hinged at the left end of the rotating plate 372, and the lower end of the top extension rod 375 is hinged to the square frame 371, a grinding block 377 of an arc-shaped structure is mounted on the right side of the lower inner wall of the square frame 371 through a plurality of square spring rods 376, and the upper right side of the grinding block 377 is set as an inclined surface.

[0058] The grinding unit 37 can scrape and grind the burrs at the drilled holes on the inner wall of the metal tube to make the inner wall of the metal tube smoother; specifically, when the connecting plate 34 moves to the right, the connecting plate 34 finally drives the scraper 374 and the grinding block 377 to move to the right into the metal tube through the rotating shaft 39, and when the grinding block 377 moves to the left end of the metal tube, the inclined surface of the grinding block 377 and the metal tube cooperate to drive the grinding block 377 to move downward, and at the same time, under the action of the square spring rod 376, the grinding block 377 is attached to the inner wall of the metal tube, and when the scraper 374 moves to the left end of the metal tube, the metal tube drives the rotating plate 372 to rotate to the left through the scraper 374, and under the action of the extension rod 375, the scraper 374 can be attached to the inner wall of the metal tube.

[0059] When the connecting plate 34 moves to the left, the connecting plate 34 eventually drives the scraper 374 and the grinding block 377 to move to the left to the initial position through the rotating shaft 39, so that the scraper 374 and the grinding block 377 can completely scrape and grind the burrs at the drilled holes on the inner wall of the metal tube in turn.

[0060] It should be noted that the drill bit of the drilling device drills a hole from the outer wall of the disc-type scaffolding metal pipe to the inner wall of the metal pipe, resulting in burrs usually existing at the drilling hole on the inner wall of the metal pipe.

[0061] See also Figure 7 , Fig. 9 and Fig.10 A clearance hole 311 is provided on the back plate 31 and located on the rear side of the transmission rod 33, which runs through the left and right ends thereof.
