Description

Technical Field

[0001] The present invention relates to the technical field of elevator guide rails, and particularly relates to an automatic drilling device for elevator guide rails. Background Art

[0002] Elevator guide rails are an important part of the elevator system. Their main function is to guide the elevator car or counterweight device to move up and down along a predetermined path. The length of the elevator guide rail is determined according to the height of the elevator shaft. For particularly high elevator shafts, a single guide rail may not meet the length requirements. In this case, multiple sections of guide rails need to be connected through joints. The standard length of each section of the guide rail is usually about 6 meters. Holes need to be drilled at both ends of the guide rail at the connection for installing connecting pieces.

[0003] Currently, when drilling elevator guide rails, usually the guide rail to be drilled is fixed on the processing platform through a fixture to ensure that the guide rail does not move during the drilling process. Then, two drilling devices are used to drill the two ends of the guide rail to be drilled simultaneously, or the drilling device is used to drill the two ends of the guide rail to be drilled one by one. However, for relatively long guide rails, if two drilling devices are used to clamp and drill both ends simultaneously, the long clamping and supporting mechanism will cause the overall equipment to occupy a large space and have a high cost. Secondly, if a single drilling device is used to drill the two ends of the guide rail to be drilled one by one, the alignment of the drilling device takes too much time, which is not convenient for quickly locking the drilling position, and the stability and drilling efficiency during the drilling operation need to be improved.

[0004] Therefore, in order to reduce the floor space of the equipment and improve the drilling efficiency, the present invention provides an automatic drilling device for elevator guide rails. Summary of the Invention

[0019] Compared with the existing technology, the advantages of the present invention are as follows:

[0020] 1. Through the cooperation of the main support table and the support mechanism for support, and the cooperation of the double-headed drilling mechanism and the limiting mechanism for processing. By drilling only one end each time, it is convenient to reduce the overall occupied space of the equipment and reduce the manufacturing cost of the equipment; the main support table and the support mechanism occupy a small space, and the position of processing is changed by moving the guide rail to be drilled on the main support table; the vertical state of the main support table and the support mechanism ensures the horizontality of the guide rail to be drilled during processing. The ball reduces the friction between the guiding member and the side wall of the guide rail to be drilled. The guiding member provides a guiding function for the movement of the guide rail when not in processing, which is convenient for quickly moving the guide rail to be drilled on the equipment with limited space so that the other end can quickly reach the processing position.

[0021] 2. Through the cooperation of the stability mechanism, the hole pitch adjustment mechanism and the double-headed drilling mechanism, the positions of the two double-headed drilling mechanisms for drilling can be quickly adjusted synchronously and equidistantly according to the width of the guide rail to be drilled before drilling, and stable drilling processing can be carried out during drilling; the two sliding members one move the same distance synchronously. The movement of the sliding member one drives the double-headed drilling mechanism to move synchronously to adjust the drilling positions of the two double-headed drilling mechanisms; the cooperation of the positioning column one and the connecting rod one increases the stability of the movement of the T-shaped plate, which is convenient for improving the stability of the drilling operation of the double-headed drilling mechanism.

[0022] 3. By the cooperation of the supporting mechanism, the stabilizing mechanism and the limiting mechanism, the processing position of the double-headed drilling mechanism is quickly locked and the processing position of the to-be-drilled guide rail is fixed; the auxiliary supporting table I drives the adjusting part to rotate, and the adjusting part locks the positions of the stabilizing mechanism and the double-headed drilling mechanism that have moved in place; the rubber plate increases the friction force with the to-be-drilled guide rail, and the symmetric rubber plates on the front and back clamp and fix the to-be-drilled guide rail; at the same time, the part of the positioning column II that moves out of the main supporting table is inserted into the positioning hole I to lock the position of the auxiliary supporting table I.

Detailed implementation mode

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0035] Refer to Figures 1 to 3 , an automatic drilling device for elevator guide rails, including a main support platform 1 and a limiting mechanism 6. A support mechanism 2, a stabilizing mechanism 3 and a limiting mechanism 6 are arranged on the main support platform 1. A hole pitch adjusting mechanism 4 is arranged on the stabilizing mechanism 3. Double-headed drilling mechanisms 5 (mature existing technologies, not described in detail here) are symmetrically arranged before and after on the hole pitch adjusting mechanism 4.

[0036] Place the guide rail to be drilled horizontally on the main support platform 1. First, move the stabilizing mechanism 3, the hole pitch adjusting mechanism 4 and the double-headed drilling mechanism 5 to the leftmost side of the top wall of the main support platform 1. Before drilling, adjust the drilling hole pitch through the hole pitch adjusting mechanism 4, and then lock the position of the stabilizing mechanism 3 through the support mechanism 2. The main support platform 1, the support mechanism 2 and the stabilizing mechanism 3 cooperate to keep one end of the guide rail to be drilled in a horizontal and stable state during drilling. After limiting the guide rail to be drilled through the limiting mechanism 6, it is clamped and fixed, and at the same time, the position of the support mechanism 2 is locked, and drilling operations are carried out through the double-headed drilling mechanism 5.

[0037] After the drilling at the left end of the guide rail is completed, the clamping of the guide rail and the locking of the position of the support mechanism 2 are released by the limit mechanism 6. The limit mechanism 6 maintains the limit of the guide rail to be drilled, providing a guiding function for the subsequent movement of the guide rail. The support mechanism 2 resets, and the guide rail moves horizontally to the left on the main support table 1 until the rightmost end of the guide rail moves to the rightmost end of the main support table 1. Then, the stabilizing mechanism 3, the hole pitch adjusting mechanism 4, and the double-headed drilling mechanism 5 are moved to the rightmost side of the top wall of the main support table 1. The position of the stabilizing mechanism 3 is locked by the support mechanism 2. After the limit mechanism 6 repeats the above operations, the second drilling operation is performed by the double-headed drilling mechanism 5.

[0038] Refer to Figures 1 to 2 , the support mechanism 2 includes an auxiliary support table one 21 and an auxiliary support table two 22. The left and right side walls of the main support table 1 are symmetrically and rotatably connected with the auxiliary support table one 21 and the auxiliary support table two 22. The top walls of the auxiliary support table one 21 and the auxiliary support table two 22 are both symmetrically fixed with stabilizing rods 23 that incline upward to the positive upper side of the main support table 1 in the front and back. Positioning holes one 24 are provided at one ends of the stabilizing rods 23 far from the corresponding auxiliary support table one 21 and the corresponding auxiliary support table two 22. The top walls of the auxiliary support table one 21 and the auxiliary support table two 22 are both symmetrically fixed with adjusting members 25 in the front and back.

[0039] Refer to Figures 1 to 3 , the stabilizing mechanism 3 includes a slide rail one 31. Slide rails one 31 in the left and right directions are symmetrically provided on the top wall of the main support table 1. A stabilizing component 32 for supporting and stabilizing the drilling operation is provided on the slide rail one 31, and a locking component one 33 is provided on the stabilizing component 32.

[0040] Refer to Figure 3 , the stabilizing component 32 includes a U-shaped frame 321. The U-shaped frame 321 is slidably connected to the two slide rails one 31 together. Symmetrically fixed to the inner walls of the vertical sections of the U-shaped frame 321 close to each other are slide rails two 322 in the front and back. The two slide rails two 322 are connected by a connecting member 323. The top walls of the slide rails two 322 are both hinged with a connecting rod one 324 through a slider.

[0041] Refer to Figures 2 to 4 , the locking component one 33 includes an inverted L-shaped member 332. The bottom parts inside the vertical sections of the U-shaped frame 321 are both slidably connected with the inverted L-shaped member 332 up and down through a spring (not shown in the figure). Fixed to the top wall of the inverted L-shaped member 332 is an arc-shaped member 331 arranged on the side of the vertical section of the U-shaped frame 321. The arc-shaped member 331 is adapted to the adjusting member 25. A hole position adapted to the bottom end of the inverted L-shaped member 332 is provided on the slide rail one 31; a hydraulic rod 34 is installed on the top wall of the connecting member 323, and a positioning hole two 35 is provided in the middle of the top wall of the U-shaped frame 321.

[0042] Refer to Figure 1 , Figure 3 and Figure 5, the hole pitch adjusting mechanism 4 includes a T-shaped plate 41, a first positioning column 42, and an adjusting component 43 for adjusting the hole pitch during drilling operations; a horizontally arranged T-shaped plate 41 is fixedly mounted on the top wall of the output end of the hydraulic rod 34, a first positioning column 42 adapted to the second positioning hole 35 is fixedly mounted in the middle of the top wall of the T-shaped plate 41, and the bottom wall of the T-shaped plate 41 is hinged to the ends of the two first connecting rods 324 away from the second slide rail 322.

[0043] Refer to Figure 3 and Figure 5 , the adjusting component 43 includes a third slide rail 431. Third slide rails 431 are provided at the three ends of the T-shaped plate 41. A first sliding member 432 is slidably connected back and forth on the two corresponding third slide rails 431, and a second sliding member 433 is slidably connected left and right on the third slide rail 431 on the right side. Second connecting rods 434 are respectively rotatably connected between the two first sliding members 432 and the second sliding member 433. The side wall of the second sliding member 433 is connected to the output end of the electric push rod 435 mounted on the corresponding third slide rail 431.

[0044] Refer to Figure 2 and Figure 5 , the two double-headed drilling mechanisms 5 are respectively mounted on the bottom walls of the two corresponding first sliding members 432. Slots adapted to the drilling adjustment spaces of the double-headed drilling mechanisms 5 are provided on the left and right parts of the top wall of the main support platform 1.

[0045] Before drilling, the output end of the electric push rod 435 moves to push the second sliding member 433 to slide in the corresponding third slide rail 431. At the same time, through the traction of the second connecting rod 434, the two first sliding members 432 are pushed to slide in the corresponding third slide rails 431. When the electric push rod 435 pushes the second sliding member 433 away from the middle of the T-shaped plate 41, the two first sliding members 432 move closer synchronously by the same distance. When the electric push rod 435 pushes the second sliding member 433 closer to the middle of the T-shaped plate 41, the two first sliding members 432 move away synchronously by the same distance. The movement of the first sliding member 432 drives the double-headed drilling mechanism 5 to move synchronously, so as to synchronously and equidistantly and quickly adjust the drilling positions of the two double-headed drilling mechanisms 5 before drilling, and adjust the hole pitch of the two double-headed drilling mechanisms 5 according to the width of the guide rail to be drilled.

[0046] Push the U-shaped frame 321 to slide to the leftmost end on the first slide rail 31. The U-shaped frame 321 drives the hole pitch adjusting mechanism 4 and the double-headed drilling mechanism 5 to perform synchronous displacement. Push the first auxiliary support platform 21 to rotate clockwise by ninety degrees, so that an angle of ninety degrees is formed between the first auxiliary support platform 21 and the main support platform 1. Horizontally place the guide rail to be drilled on the main support platform 1, and push the guide rail to be drilled to move so that its left side wall moves to be close to the right side wall of the first auxiliary support platform 21 in the vertical state, ensuring the horizontality of the guide rail to be drilled during processing.

[0047] When the auxiliary support platform 21 rotates, it drives the adjusting member 25 to approach the arc-shaped member 331 until the arc-shaped member 331 and the inverted L-shaped member 332 are pushed downward. The spring connected between the inverted L-shaped member 332 and the U-shaped frame 321 is stretched, and the inverted L-shaped member 332 moves downward and engages into the corresponding hole positions on the first slide rail 31 to lock the position of the stabilizing mechanism 3.

[0048] Refer to Figure 1 、 Figure 6 and Figure 8 As shown in FIGS.

[0049] Refer to Figure 1 、 Figures 6 to 7 As shown in FIGS.

[0050] Refer to Figure 1 、 Figures 7 to 9 As shown in FIGS.

[0051] The motor 635 drives the gear 634 to rotate, and the gear 634 drives the racks 633 engaged on the left and right sides to move forward and backward synchronously. When the gear 634 rotates forward, the racks 633 pull the corresponding fixing frames 631 to move closer to each other. The fixing frames 631 drive the guiding members 61 to move closer to the drilling guide rail until the balls 62 are tightly attached to the side wall of the drilling guide rail, so that the guiding members 61 limit the drilling guide rail.

[0052] The rack 633 continues to pull the fixing bracket 631 to move. The guide 61 stops moving, and the spring between the fixing bracket 631 and the guide 61 is compressed. The fixing bracket 631 slides within the guide 61. The fixing bracket 631 drives the rubber plate 632 to change from the state inside the groove on the guide 61 to the state where part of it moves out of the groove on the guide 61 until the side wall of the rubber plate 632 is closely attached to the side wall of the to-be-drilled guide rail. The rubber plate 632 increases the frictional force between the guide 61, the ball 62 and the to-be-drilled guide rail, and the symmetrically arranged rubber plates 632 on the front and back can clamp and fix the to-be-drilled guide rail front and back, making the guide rail centered front and back.

[0053] When the rack 633 drives the guide 61 and the fixing bracket 631 to move, the spring rod 641 on the front side rack 633 gradually approaches the rear balance plate 642, and the rear spring rod 641 gradually approaches the front balance plate 642 until the spring rod 641 pushes the balance plate 642 to drive the positioning post two 643 to move. The spring connected to the inside of the main support platform 1 by the balance plate 642 is stretched, and the positioning post two 643 changes from the state inside the main support platform 1 to the state where part of it moves out of the inside of the main support platform 1. The part of the positioning post two 643 that moves out of the main support platform 1 is inserted into the positioning hole one 24 to lock the position of the auxiliary support platform one 21.

[0054] Refer to Figure 2 、 Figure 3 and Figure 5 After the position locking of the support mechanism 2 and the stabilizing mechanism 3 is completed and the limiting mechanism 6 limits the to-be-drilled guide rail, the output end of the hydraulic rod 34 drives the T-shaped plate 41 to move downward. The T-shaped plate 41 drives the double-headed drilling mechanism 5 to move downward for drilling operations. During the downward movement of the T-shaped plate 41, the first connecting rod 324 tilts adaptively, and at the same time, the slider connected to the bottom end of the first connecting rod 324 slides adaptively back and forth on the second slide rail 322. The T-shaped plate 41 drives the first positioning post 42 to move within the second positioning hole 35. The cooperation between the first positioning post 42 and the first connecting rod 324 increases the stability of the T-shaped plate 41 during movement, facilitating the improvement of the stability of the double-headed drilling mechanism 5 during drilling operations.

[0055] When the drilling at the left end of the to-be-drilled guide rail is completed, the motor 635 rotates in the reverse direction to drive the rack 633 and the balance plate 642 to reset. The spring connected between the balance plate 642 and the main support platform 1 contracts, and the positioning post two 643 resets to release the locking of the position of the auxiliary support platform one 21. At the same time, the fixing bracket 631 and the rubber plate 632 reset to release the front and back clamping and fixing of the to-be-drilled guide rail. The motor 635 stops rotating, and the guide 61 maintains the state of limiting the to-be-drilled guide rail, providing a guiding function for the subsequent movement of the guide rail. The guide rail moves horizontally to the left between the two guides 61 on the main support platform 1 until the rightmost end of the guide rail moves to the rightmost end of the main support platform 1. The ball 62 reduces the frictional force between the guide 61 and the side wall of the guide rail, avoiding unnecessary wear.

[0056] When the rightmost end of the guide rail moves to the rightmost end of the main support platform 1, it pushes the U-shaped frame 321 to slide to the rightmost end on the first slide rail 31. The U-shaped frame 321 drives the hole pitch adjustment mechanism 4 and the double-headed drilling mechanism 5 to perform synchronous displacement, pushes the second auxiliary support platform 22 to rotate counterclockwise by ninety degrees. When the right side wall of the drilling guide rail moves to be close to the left side wall of the vertically placed second auxiliary support platform 22, the support mechanism 2 relocks the position of the stability mechanism 3; the motor 635 drives the second positioning column 643 to lock the position of the second auxiliary support platform 22, and the rubber plate 632 re-clamps and fixes the drilling guide rail before and after, and then drilling processing is carried out through the double-headed drilling mechanism 5.

[0057] Refer to Figures 1 - 9 , the specific operation steps of this elevator guide rail automatic drilling equipment are as follows:

[0058] Before drilling, the two first sliding parts 432 move away from each other synchronously by the same distance. The movement of the first sliding part 432 drives the double-headed drilling mechanism 5 to move synchronously, so as to realize the synchronous and equidistant rapid adjustment of the drilling positions of the two double-headed drilling mechanisms 5 before drilling.

[0059] First, perform the drilling operation at the left end. First, move the stability mechanism 3, the hole pitch adjustment mechanism 4 and the double-headed drilling mechanism 5 to the leftmost side of the top wall of the main support platform 1. Place the drilling guide rail horizontally on the main support platform 1, push the first auxiliary support platform 21 to rotate clockwise by ninety degrees, and the adjusting part 25 cooperates with the first locking component 33 to lock the position of the U-shaped frame 321; the motor 635 drives the guiding part 61 to limit the drilling guide rail, and then the rubber plate 632 clamps and fixes the drilling guide rail before and after. Furthermore, the second positioning column 643 is inserted into the first positioning hole 24 to lock the position of the first auxiliary support platform 21, and the hydraulic rod 34 drives the double-headed drilling mechanism 5 to move up and down for drilling operations.

[0060] Before performing the drilling operation at the right end, the motor 635 drives the second positioning column 643 to release the locking of the first auxiliary support platform 21, the first auxiliary support platform 21 resets, the rubber plate 632 releases the front and rear clamping and fixing of the guide rail, and the guiding part 61 maintains the limit of the guide rail to provide a guiding function for the subsequent movement of the guide rail.

[0061] When performing the drilling operation at the right end, move the rightmost end of the guide rail to the rightmost end of the main support platform 1, and then move the stability mechanism 3, the hole pitch adjustment mechanism 4 and the double-headed drilling mechanism 5 to the rightmost side of the top wall of the main support platform 1. Push the second auxiliary support platform 22 to rotate counterclockwise by ninety degrees, and the support mechanism 2 relocks the position of the stability mechanism 3; re-clamp and fix the drilling guide rail before and after, lock the position of the support mechanism 2, and then the hydraulic rod 34 drives the double-headed drilling mechanism 5 to move up and down for drilling operations again.

[0062] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention should cover within the protection scope of the present invention any equivalent replacement or change made according to the technical solution and inventive concept of the present invention.
