Description

Technical Field

[0001] The invention relates to the technical field of elevator component processing, in particular to an elevator traction wheel drilling processing device. Background Art

[0002] The elevator traction sheave is a key component in the elevator traction drive system. The mounting hole of the traction sheave is connected to the main shaft of the traction machine, and then connected to the car and counterweight through the traction steel rope. The main function of the traction sheave is to transmit power to realize the lifting and lowering of passengers and goods.

[0003] The traction sheave is mainly formed by a casting process. During casting, multiple circumferentially evenly distributed structural holes are reserved to reduce the overall weight and material usage. In some special design requirements, in order to increase the heat dissipation area on the surface of the traction sheave and improve the heat dissipation efficiency, reduce weight, suppress vibration and release stress, the non-critical areas of the traction sheave will be evenly drilled to ensure that the requirements are met without affecting the function and safety performance of the traction sheave.

[0004] At present, when drilling holes on the traction wheel, the traction wheel is first fixed to the drilling machine, and the area to be drilled is manually marked, and then the marked position is drilled by the drilling machine. It should be noted that both the inner and outer rings of the traction wheel need to be drilled and the drilled through holes are evenly distributed circumferentially, but the following problems exist in the current operation process: 1. The current drilling operation can only perform one through hole at a time. After a single through hole is formed, the drill bit needs to be moved down to the next drilling position, and the drilling operation is repeated to complete the formation of multiple through holes. In this way, the overall operation time of the above operation process is long and the overall efficiency is low. Secondly, the method of drilling holes according to the marked position makes it easy for the accuracy of the drilling position to be reduced due to the marking error, resulting in a large processing error.

[0005] 2. In the current single drilling operation, the drilling operation is performed by moving the drill bit in the drilling machine downward. The angle between the drill bit and the traction wheel is easily changed due to the drilling vibration during the processing, thereby affecting the quality of the through hole formed. In severe cases, it will affect the function and safety performance of the traction wheel. Secondly, during the downward drilling operation, the drill bit exerts a force on the traction wheel, which affects the balance state of the traction wheel and affects the quality of the drilling operation.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, a drilling mechanism 7 is arranged on the central shaft 4, and the drilling mechanism 7 includes a triangular plate 70. The triangular plate 70 slides up and down on the central shaft 4, and the triangular plate 70 is an equilateral triangle. The triangular plate 70 is driven by an external hydraulic cylinder 1 (not shown in the figure) to move up and down. Fixed columns 700 with horizontal axes are fixed on the three sides of the triangular plate 70. A horizontal plate 701 is slidably arranged on the fixed column 700 along its axis direction. A mounting plate 702 is arranged on one side of the lower end surface of the horizontal plate 701. A drilling device is arranged on the lower end surface of the mounting plate 702. The drilling device includes a drill bit 703 with a vertical axis. A guiding unit 71 for guiding the drilling device to perform drilling operations is arranged on the base plate 1.

[0034] When working, first place the required traction wheel on the bottom plate 1 with the axis vertical. It should be noted that the upper end surface of the bottom plate 1 is provided with a plurality of free-rolling balls (not shown in the figure) for reducing the friction between the traction wheel and the bottom plate 1. During the above placement process, the central shaft 4 passes through the traction wheel mounting hole, and then the mounting circular plate 5 and the branch plate 60 thereon are installed on the central shaft 4 by plug-in matching, and the two arc plates 61 on the same branch plate 60 on the mounting circular plate 5 are respectively inserted into the mounting hole and the structural hole, and the drive unit 6 2 works so that the two arc plates 61 on the same branch plate 60 clamp the traction wheel so that the axis of the traction wheel is in line with the axis of the central axis 4, and then the triangle plate 70 is inserted and assembled on the central axis 4 from top to bottom, and the guide unit 71 guides the triangle plate 70 to rotate to a specified position, and then the external hydraulic cylinder works to drive the triangle plate 70 to move from top to bottom so that the drill bit 703 performs a drilling operation, and then the triangle plate 70 is rotated by the guide unit 71 and the position of the horizontal plate 701 is adjusted to realize the drilling operation at different positions on the traction wheel.

[0035] like Figure 2 and Figure 3As shown, the drilling mechanism 7 also includes a center column 72. The upper end surface of the triangular plate 70 is fixedly provided with a center column 72 with an axis located at its center and extending vertically upward. A driving plate 720 is slidably sleeved up and down on the center column 72. The driving plate 720 is driven by an external hydraulic cylinder 2 (not shown in the figure) to move up and down. A driving bar 721 is hinged between the driving plate 720 and the horizontal plate 701. The horizontal plate 701 is divided into a U-shaped segment, a rectangular segment one and a rectangular segment two in the horizontal direction, wherein the thickness of the rectangular segment one is greater than the thickness of the rectangular segment two, and the rectangular segment two on the horizontal plate 701 is inserted into the U-shaped segment of the adjacent horizontal plate 701.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the guide unit 71 includes a guide assembly, and a plurality of groups of circumferentially evenly distributed guide assemblies are fixedly provided on the upper end surface of the base plate 1, and the guide assembly includes two fixed cylinders 710 radially distributed along the base plate 1, and a guide column 711 with an axis extending from top to bottom is fixedly provided on the end surface of the horizontal plate 701 away from the triangular plate 70 through a horizontal bar.

[0037] like Figure 2 and Figure 3 As shown, a truncated cone cylinder 712 with a larger top and a smaller bottom is fixedly provided on the upper end surface of the fixed cylinder 710 , and the diameter of the guide column 711 is the same as the inner cylinder diameter of the fixed cylinder 710 .

[0038] like Figure 2 and Figure 3 As shown, a limiting group is arranged between two adjacent horizontal plates 701, and the limiting group includes a sliding groove 713. The lower end surface of the U-shaped section of the horizontal plate 701 is provided with a sliding groove 713, and the upper end surface of the mounting plate 702 is slidably arranged in the sliding groove 713 through a sliding block. Four limiting columns 714 arranged in a diamond shape are fixedly arranged on the upper end surface of the mounting plate 702, and the rectangular section 2 of the adjacent horizontal plate 701 passes through the four limiting columns 714.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the guide unit 71 also includes an annular plate 715, and the upper end surface of the base plate 1 is rotatably provided with an annular plate 715 coaxial therewith, and the upper end surface of the annular plate 715 is fixedly provided with a support plate 716 corresponding to the mounting plate 702 one by one, and the upper section of the support plate 716 is a U-shaped section, and two mutually symmetrical snap-in grooves 717 are provided in the U-shaped area of ​​the U-shaped section of the support plate 716, and a moving block 718 is slidably provided in the snap-in groove 717, and a horizontal column 719 with a horizontal axis and slidingly passing through the corresponding moving block 718 is fixedly provided on the side of the mounting plate 702.

[0040] During operation, after the traction wheel is placed and the traction wheel is limitedly clamped by the clamping mechanism 6, the axis of the traction wheel is in line with the axis of the central axis 4, and then the triangular plate 70 and the horizontal plate 701 thereon are inserted from top to bottom onto the central axis 4, and the external hydraulic cylinder 2 works to make the driving plate 720 move up and down, and the driving plate 720 drives the three horizontal plates 701 to move synchronously along the axis direction of the fixed column 700 through the three driving bars 721 thereon, and the horizontal plate 701 drives the corresponding guide column 711 to move synchronously through the horizontal bar, and when the guide column 711 moves to the top of the corresponding fixed cylinder 710 on the outside, it stops moving, and the triangular plate 70 is moved downward, so that the triangular plate 70 drives the guide column 711 to move downward synchronously, and during the downward movement of the guide column 711, it first contacts the arc surface of the conical cylinder 712, and the conical cylinder 712 guides the guide column Column 711 is aligned with fixed tube 710. As guide column 711 continues to move downward, guide column 711 is inserted into fixed tube 710. Therefore, the position of corresponding horizontal plate 701 is limited and fixed through the cooperation between three guide columns 711 and corresponding fixed tube 710 on the outside. Because the rectangular sections on the three horizontal plates 701 are all inserted into the U-shaped sections on the adjacent horizontal plates 701, the triangular structure formed by the three limited horizontal plates 701 is used as a reference frame for the subsequent drilling operation. At the same time, fixed tube 710 not only serves as a guide for the downward movement of guide column 711, but also provides a circumferential limiting effect for horizontal plate 701 after cooperating with guide column 711, thereby improving the stability during the drilling operation and avoiding the problem of shaking of horizontal plate 701 and the drilling equipment thereon affecting the drilling operation.

[0041] During the process of the horizontal plate 701 moving downward and the guide column 711 docking with the fixed cylinder 710, the three horizontal plates 701 all move synchronously along the corresponding fixed column 700 at the same speed. At the same time, the rectangular section 2 of the adjacent horizontal plate 701 is limited by the four limit columns 714 on the same mounting plate 702, and the mounting plate 702 slides synchronously along the sliding groove 713, so the mounting plate 702 and the drill bit 703 are always located at the junction of the two corresponding horizontal plates 701, that is, the three drill bits 703 are evenly distributed circumferentially about the axis of the central axis 4, and then the drilling operation is carried out. After the drilling operation is completed, the triangular plate 70 moves up, and the staff rotates the triangular plate 70 so that the guide column 711 cooperates with the different fixed cylinders 710 on the outside to complete the drilling operation requirements at all drilling positions of the outer circle. The above-mentioned drilling operation method can be used to perform drilling operations at three locations simultaneously, avoiding the need to repeatedly drill a single through hole, thereby improving the processing efficiency during the overall processing process, and maintaining the force balance of the traction wheel through the three triangularly distributed synchronous drilling operations. It should be noted that when the outer fixed cylinder 710 cooperates with the guide column 711, the drill bit 703 is located directly above the outermost through hole, and when the inner fixed cylinder 710 cooperates with the guide column 711, the drill bit 703 moves to directly above the inner through hole. Therefore, by adjusting the position of the horizontal plate 701, the adjustment process of the triangular distribution frame of different sizes with the same axis center is realized, which is convenient for adapting to the drilling requirements of through holes at different diameters of the traction wheel, that is, when the drilling requirements of multiple through holes of the outer ring are completed, the position of the horizontal plate 701 is adjusted by moving the driving plate 720, so that the guide column 711 cooperates with the inner fixed cylinder 710, and then the drilling operation of the inner ring drilling position can be carried out.

[0042] When installing the triangle plate 70, the moving block 718 is installed in the U-shaped section of the corresponding support plate 716 through the cooperation between the moving block 718 and the corresponding snap-in groove 717. Therefore, in the process of the triangle plate 70 and the horizontal plate 701 moving downward for drilling operation, the up and down movement process of the mounting plate 702 is guided and limited by the cooperation between the moving block 718 and the snap-in groove 717. The cooperation between the guide column 711 and the fixed cylinder 710 and the cooperation between the moving block 718 and the snap-in groove 717 ensures that the drill bit 703 always moves vertically downward stably, thereby improving the accuracy of the drilling operation.

[0043] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the clamping mechanism 6 also includes a rectangular block 63, and a rectangular block 63 is installed on the branch plate 60 to slide radially through the mounting circular plate 5, and the lower end surface of the upper rectangular block 63 is fixedly connected to the corresponding arc plate 61, and the outer arc surfaces of the two arc plates 61 on the same branch plate 60 are opposite.

[0044] like Figure 4 and Figure 6 As shown, a docking post 64 is fixedly provided on the upper end surface of the rectangular block 63 below, and a docking groove 640 corresponding to the docking post 64 is opened on the lower end surface of the arc plate 61, and the lower side of the docking groove 640 is chamfered.

[0045] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the driving unit 62 includes a vertical plate 620, the upper end surface of the upper rectangular block 63 and the lower end surface of the lower rectangular block 63 are both fixedly provided with the vertical plate 620, the upper end surface of the upper branch plate 60 and the lower end surface of the lower branch plate 60 are both fixedly provided with a support block 621, and a bidirectional screw rod 622 with a horizontal axis and pointing to the axis of the central axis 4 is rotatably provided on the support block 621, the bidirectional screw rod 622 passes through the corresponding vertical plate 620 and is threadedly matched with the corresponding vertical plate 620, the upper end surface of the mounting circular plate 5 and the lower end surface of the base circular plate 3 are both rotatably provided with a rotating cylinder 623 with a vertical axis, the opposite back surfaces of the two rotating cylinders 623 are fixedly provided with a bevel gear 1 624, and the end surface of the bidirectional screw rod 622 close to the rotating cylinder 623 is fixedly provided with a bevel gear 2 625 meshing with the corresponding bevel gear 1 624, wherein the thread directions of the two bidirectional screw rods 622 facing each other up and down are opposite, and the central axis 4 is connected to an external motor (not shown in the figure).

[0046] like Figure 1 , Figure 4 and Figure 5 As shown, the driving unit 62 also includes a circumferential groove 626, and the upper circumferential surface of the central shaft 4 is provided with a plurality of circumferential grooves 626 evenly distributed circumferentially, and a plurality of clamping blocks 627 that slide in cooperation with the plurality of circumferential grooves 626 are fixedly provided on the upper bevel gear 624.

[0047] During operation, first place the required traction wheel on the base plate 1 with the axis vertical, and make the central axis 4 pass through the traction wheel mounting hole, then install the mounting circular plate 5 and the branch plate 60 thereon to the central axis 4 by plug-in fitting, and make the two arc plates 61 on the same branch plate 60 on the mounting circular plate 5 be inserted into the mounting hole and the structural hole respectively, and make the docking column 64 be stuck in the docking groove 640 on the corresponding arc plate 61, at this time, the upper branch plate 60, the corresponding arc plate 61 and the corresponding lower branch plate 60 are integrated, so as to ensure the internal expansion and limiting effect of the arc plate 61 in the subsequent process.

[0048] After that, the external motor works to drive the central shaft 4 and the lower bevel gear 1 624 to rotate synchronously. At the same time, the central shaft 4 drives the upper bevel gear 1 624 to rotate synchronously through the cooperation between the circumferential groove 626 and the clamping block 627. The meshing between the bevel gear 1 624 and the corresponding three bevel gear 2 625 drives the bevel gear 2 625 and the corresponding bidirectional screw rod 622 to rotate synchronously. The threaded cooperation between the bidirectional screw rod 622 and the corresponding vertical plate 620 makes the two arc plates 61 on the same branch plate 60 approach each other, and finally the arc plate 61 is pressed against the arc inner wall of the corresponding structural hole and the mounting hole. The arc plates 61 on the three branch plates 60 are pressed against the inner wall of the structural hole and the mounting hole to achieve The inner expansion limit of the traction wheel makes the axis of the central shaft 4 and the axis of the traction wheel, ensuring that the through holes formed in the subsequent drilling operation are evenly distributed circumferentially with the axis of the traction wheel. Secondly, in the above process, the upper vertical plate 620 and the lower vertical plate 620 move synchronously to ensure the expansion effect of the arc plate 61 on the traction wheel, avoiding the problem of the axis of the traction wheel deviating due to the expansion force applied at one end affecting the expansion limit process. At the same time, the two upper branch plates 60, the two arc plates 61 and the two lower branch plates 60 in the two upper and lower branch plates 60 form a stable rectangular frame together, and the stability of the traction wheel during the drilling operation is ensured by the three rectangular frames.

[0049] In the above process, through the plug-in installation method between the clamping block 627 and the circumferential groove 626, it is ensured that when the installation circular plate 5 moves downward, the central shaft 4 can still drive the upper bevel gear 624 to rotate synchronously. Secondly, through this plug-in installation method and the plug-in installation method of the triangular plate 70, the subsequent traction wheel placement and removal process is smoothly carried out, which simplifies the equipment operation process and improves the convenience of the equipment.
