Description

Technical Field

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

[0002] Elevator guide rails are an important component in the elevator system. Their main function is to guide the elevator car or counterweight device to run up and down along a predetermined path. The length of the elevator guide rails is determined by the height of the elevator shaft. For particularly high elevator shafts, a single guide rail may not be able to meet the length requirements. At this time, multiple sections of guide rails are required to be connected through joints. The standard length of each section of guide rail is usually about 6 meters. Holes need to be drilled at both ends of the guide rails to install the connectors.

[0003] At present, when drilling holes in elevator guide rails, the guide rail to be drilled is usually first fixed on the processing platform by a clamp to ensure that the guide rail will not move during the drilling process, and then two drilling devices are used to drill holes at both ends of the guide rail to be drilled at the same time, or the two ends of the guide rail to be drilled are drilled one by one by the drilling devices; however, for a long guide rail, if two drilling devices are used to clamp and drill holes at both ends at the same time, the long clamping support mechanism will cause the overall equipment to occupy a large space and have high costs; secondly, if one drilling device is used to drill holes at both ends of the guide rail to be drilled one by one, it takes too much time to locate the drilling device, which is not convenient for quickly locking the drilling processing position, and the stability and drilling efficiency during the drilling operation need to be improved.

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

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3 An automatic drilling device for elevator guide rails includes a main supporting platform 1 and a limiting mechanism 6. The main supporting platform 1 is provided with a supporting mechanism 2, a stabilizing mechanism 3 and a limiting mechanism 6. The stabilizing mechanism 3 is provided with a hole spacing adjusting mechanism 4. The hole spacing adjusting mechanism 4 is symmetrically provided with a double-head drilling mechanism 5 (existing mature technology, which will not be described in detail here).

[0033] Place the guide rail to be drilled horizontally on the main support platform 1, first move the stabilizing mechanism 3, the hole spacing adjusting mechanism 4 and the double-head drilling mechanism 5 to the leftmost side of the top wall of the main support platform 1, adjust the drilling hole spacing through the hole spacing adjusting mechanism 4 before drilling, and then lock the position of the stabilizing mechanism 3 through the supporting mechanism 2, the main support platform 1, the supporting 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, limit the guide rail to be drilled through the limiting mechanism 6 and then clamp it, and at the same time lock the position of the supporting mechanism 2, and perform drilling operations through the double-head drilling mechanism 5.

[0034] When the left end of the guide rail is drilled, the clamping of the guide rail and the locking of the position of the supporting mechanism 2 are released by the limiting mechanism 6. The limiting mechanism 6 keeps the limit of the guide rail to be drilled to provide guidance for the subsequent movement of the guide rail. The supporting mechanism 2 is reset, and the guide rail moves horizontally to the left on the main supporting platform 1 until the rightmost end of the guide rail moves to the rightmost end of the main supporting platform 1, and then the stabilizing mechanism 3, the hole spacing adjustment mechanism 4 and the double-head drilling mechanism 5 are moved to the rightmost side of the top wall of the main supporting platform 1, and the position of the stabilizing mechanism 3 is locked by the supporting mechanism 2. After the limiting mechanism 6 repeats the above operation, the second drilling operation is carried out through the double-head drilling mechanism 5.

[0035] Reference Figure 1 to Figure 2 The supporting mechanism 2 includes an auxiliary supporting platform 1 21 and an auxiliary supporting platform 2 22. The left and right side walls of the main supporting platform 1 are symmetrically connected to the auxiliary supporting platform 1 21 and the auxiliary supporting platform 2 22. The top walls of the auxiliary supporting platform 1 21 and the auxiliary supporting platform 2 22 are symmetrically fixed with stabilizing rods 23 inclined toward the top of the main supporting platform 1 front and back. The stabilizing rods 23 are provided with positioning holes 1 24 at one end away from the corresponding auxiliary supporting platform 1 21 and the corresponding auxiliary supporting platform 2 22. The top walls of the auxiliary supporting platform 1 21 and the auxiliary supporting platform 2 22 are symmetrically fixed with adjusting parts 25 front and back.

[0036] Reference Figures 1 to 3 The stabilizing mechanism 3 includes a slide rail 31. The top wall of the main support platform 1 is symmetrically provided with a slide rail 31 facing left and right. A stabilizing component 32 for supporting and stabilizing the drilling operation is arranged on the slide rail 31. A locking component 33 is arranged on the stabilizing component 32.

[0037] Reference Figure 3 The stabilizing assembly 32 includes a U-shaped frame 321, two slide rails 1 31 are slidably connected to the U-shaped frame 321, and slide rails 2 322 are symmetrically fixedly connected to the inner walls of the vertical sections of the U-shaped frame 321, and the two slide rails 2 322 are connected by a connecting piece 323, and the top walls of the slide rails 2 322 are hinged with connecting rods 1 324 through sliders.

[0038] Reference Figures 2 to 4 The locking assembly 33 includes an inverted L-shaped member 332. The bottom end of the vertical section of the U-shaped frame 321 is connected to the inverted L-shaped member 332 by a spring (not shown in the figure) for sliding up and down. The top wall of the inverted L-shaped member 332 is fixed with 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 adjustment member 25. A hole position adapted to the bottom end of the inverted L-shaped member 332 is opened on the slide rail 31; a hydraulic rod 34 is installed on the top wall of the connecting member 323, and a positioning hole 2 35 is opened in the middle of the top wall of the U-shaped frame 321.

[0039] Reference Figure 1 , Figure 3 and Figure 5The hole spacing adjustment mechanism 4 includes a T-shaped plate 41, a positioning column 42 and an adjustment component 43 for adjusting the hole spacing during drilling operations; a horizontal T-shaped plate 41 is fixed to the top wall of the output end of the hydraulic rod 34, a positioning column 42 matched with the positioning hole 35 is fixed to 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 connecting rods 324 away from the slide rails 322.

[0040] Reference Figure 3 and Figure 5 The adjustment component 43 includes a slide rail 3 431. The three ends of the T-plate 41 are all provided with slide rails 3 431. The two corresponding front and rear slide rails 431 are connected with slide members 1 432 for front-back sliding movement. The right slide rail 3 431 is connected with slide member 2 433 for left-right sliding movement. The two slide members 1 432 and one slide member 2 433 are respectively connected with connecting rod 2 434 for rotation. The side wall of the slide member 2 433 is connected with the output end of the electric push rod 435 installed on the corresponding slide rail 3 431.

[0041] Reference Figure 2 and Figure 5 The two double-head drilling mechanisms 5 are respectively installed on the bottom walls of the two corresponding sliding members 432 at the front and rear, and the left and right parts of the top wall of the main support platform 1 are provided with slots adapted to the drilling adjustment space of the double-head drilling mechanism 5.

[0042] Before drilling, the output end of the electric push rod 435 moves to push the sliding member 2 433 to slide in the corresponding sliding rail 3 431, and at the same time, the two sliding members 1 432 are pushed to slide in the corresponding sliding rail 3 431 through the traction of the connecting rod 2 434. When the electric push rod 435 pushes the sliding member 2 433 away from the middle of the T-shaped plate 41, the two sliding members 1 432 move synchronously towards each other by the same distance. When the electric push rod 435 pushes the sliding member 2 433 close to the middle of the T-shaped plate 41, the two sliding members 1 432 move synchronously away from each other by the same distance. The movement of sliding member 1 432 drives the double-head drilling mechanism 5 to move synchronously, so as to synchronously and equidistantly adjust the drilling positions of the two double-head drilling mechanisms 5 quickly and synchronously before drilling, and adjust the drilling hole spacing of the two double-head drilling mechanisms 5 according to the width of the guide rail to be drilled.

[0043] Push the U-shaped frame 321 to slide on the slide rail 31 to the leftmost end, and the U-shaped frame 321 drives the hole spacing adjustment mechanism 4 and the double-head drilling mechanism 5 to move synchronously, pushing the auxiliary support platform 21 to rotate ninety degrees clockwise, so that a ninety-degree angle is formed between the auxiliary support platform 21 and the main support platform 1, and the guide rail to be drilled is placed horizontally on the main support platform 1, and the guide rail to be drilled is pushed to move so that its left side wall moves to close to the right side wall of the auxiliary support platform 21 in a vertical state, thereby ensuring the horizontality of the guide rail to be drilled during processing.

[0044] When the auxiliary support platform 21 rotates, it drives the adjustment member 25 to approach the arc member 331 until the arc 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 in the corresponding hole on the slide rail 31, so as to lock the position of the stabilizing mechanism 3.

[0045] Reference Figure 1 , Figure 6 and Figure 8 The limiting mechanism 6 includes a guide member 61, a ball 62, a fixing component 63 for clamping and fixing the drilling operation, and a locking component 64 for locking the connection state between the supporting mechanism 2 and the main supporting platform 1. The top wall of the main supporting platform 1 is symmetrically slidably connected with the guide member 61, and a plurality of ball 62 are symmetrically and evenly distributed on the side where the two guide members 61 are close to each other.

[0046] Reference Figure 1 , Figure 6 to Figure 7 The fixing assembly 63 includes a fixing frame 631, and the side where the two guide members 61 are separated from each other is connected with the fixing frame 631 by a spring for symmetrical sliding front and back. The sides where the two fixing frames 631 are close to each other are fixed with a plurality of rubber plates 632 evenly distributed left and right. The sides where the guide members 61 are close to each other are provided with grooves corresponding to the rubber plates 632 one by one. The bottom walls of the fixing frames 631 are fixed with racks 633 that slide back and forth inside the main support platform 1; the two racks 633 are jointly meshed with a gear 634 that is rotatably connected to the inside of the main support platform 1, and the bottom wall of the gear 634 is connected to the top wall of the output end of the motor 635 installed inside the main support platform 1.

[0047] Reference Figure 1 , Figures 7 to 9 The locking assembly 2 64 includes a spring rod 641, and the side of the rack 633 away from the fixed frame 631 is fixedly connected with the spring rod 641, and the side of the spring rod 641 away from the rack 633 is provided with a balance plate 642 connected to the inside of the main support platform 1 through a spring, and the side wall of the balance plate 642 is fixed with a positioning column 2 643 adapted to the positioning hole 1 24, and the front and rear side walls of the main support platform 1 are provided with holes adapted to the positioning column 2 643.

[0048] The motor 635 drives the gear 634 to rotate, and the gear 634 drives the meshing racks 633 on the left and right sides to move forward and backward synchronously. When the gear 634 rotates forward, the rack 633 pulls the corresponding fixing frames 631 to move closer to each other, and the fixing frames 631 drive the guide member 61 to move closer to the guide rail to be drilled until the ball 62 is close to the side wall of the guide rail to be drilled, so that the guide member 61 limits the guide rail to be drilled.

[0049] The rack 633 continues to pull the fixing frame 631 to move, and the guide member 61 no longer moves. The spring between the fixing frame 631 and the guide member 61 is compressed, and the fixing frame 631 slides in the guide member 61. The fixing frame 631 drives the rubber plate 632 to change from a state of being located inside the groove on the guide member 61 to a state of partially moving out of the groove on the guide member 61, until the side wall of the rubber plate 632 is in close contact with the side wall of the guide rail to be drilled, and the friction between the guide member 61 and the ball 62 and the guide rail to be drilled is increased by the rubber plate 632, and the front-to-back symmetrical rubber plate 632 can clamp and fix the guide rail to be drilled front and back, so that the guide rail is centered front and back.

[0050] When the rack 633 drives the guide member 61 and the fixing frame 631 to move, the spring rod 641 on the front 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 column 2 643 to move, and the spring connecting the balance plate 642 and the main support platform 1 is stretched, and the positioning column 2 643 changes from a state of being located inside the main support platform 1 to a state of being partially moved out of the main support platform 1, and the part of the positioning column 2 643 moving out of the main support platform 1 is inserted into the positioning hole 1 24 to achieve locking of the position of the auxiliary support platform 1 21.

[0051] Reference Figure 2 , Figure 3 and Figure 5 After the position locking of the supporting mechanism 2 and the stabilizing mechanism 3 is completed and the limiting mechanism 6 limits the guide rail to be drilled, the output end of the hydraulic rod 34 drives the T-plate 41 to move downward, and the T-plate 41 drives the double-head drilling mechanism 5 to move downward to perform the drilling operation; during the downward movement of the T-plate 41, the connecting rod 1 324 is adaptively tilted, and at the same time, the sliding block connected to the bottom end of the connecting rod 1 324 slides adaptively back and forth on the slide rail 2 322, and the T-plate 41 drives the positioning column 1 42 to move in the positioning hole 2 35. The cooperation between the positioning column 1 42 and the connecting rod 1 324 increases the stability of the T-plate 41 during movement, which is convenient for improving the stability of the double-head drilling mechanism 5 during drilling operation.

[0052] When the drilling of the left end of the guide rail to be drilled is completed, the motor 635 rotates in the opposite 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, the positioning column 643 resets to release the lock on the position of the auxiliary support platform 21, and at the same time, the fixing frame 631 and the rubber plate 632 reset to release the front and rear clamping of the guide rail to be drilled. The motor 635 stops rotating, and the guide member 61 remains in a state of limiting the guide rail to be drilled, providing a guiding effect for the subsequent movement of the guide rail. The guide rail moves horizontally to the left between the two guide members 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, and the friction between the guide member 61 and the side wall of the guide rail is reduced by the ball 62 to avoid unnecessary wear.

[0053] When the rightmost end of the guide rail moves to the rightmost end of the main support platform 1, the U-shaped frame 321 is pushed to slide on the slide rail 1 31 to the rightmost end, and the U-shaped frame 321 drives the hole spacing adjustment mechanism 4 and the double-head drilling mechanism 5 to move synchronously, pushing the auxiliary support platform 2 22 to rotate counterclockwise ninety degrees, and the right side wall of the drilling guide rail moves to the left side wall of the auxiliary support platform 22 in a vertical state, and the support mechanism 2 re-locks the position of the stabilizing mechanism 3; the motor 635 drives the positioning column 2 643 to lock the position of the auxiliary support platform 22, and the rubber plate 632 re-clamps and fixes the drilling guide rail front and back, and then the double-head drilling mechanism 5 is used for drilling processing.

[0054] Reference Figure 1-Figure 9 The specific operation steps of this elevator guide rail automatic drilling equipment are as follows: Before drilling, the two sliding members 432 move away from each other synchronously by the same distance, and the movement of the sliding member 432 drives the double-head drilling mechanism 5 to move synchronously, so as to achieve synchronous and equidistant rapid adjustment of the drilling positions of the two double-head drilling mechanisms 5 before drilling.

[0055] First, the drilling operation is carried out on the left end. The stabilizing mechanism 3, the hole spacing adjustment mechanism 4 and the double-head drilling mechanism 5 are first moved to the leftmost side of the top wall of the main support platform 1. When the drilling guide rail is placed horizontally on the main support platform 1, the auxiliary support platform 21 is pushed to rotate ninety degrees clockwise, and the adjusting member 25 cooperates with the locking assembly 33 to lock the position of the U-shaped frame 321; the motor 635 drives the guide member 61 to limit the drilling guide rail, and then the rubber plate 632 clamps and fixes the drilling guide rail front and back, and then the positioning column 2 643 is inserted into the positioning hole 24 to lock the position of the auxiliary support platform 21, and the hydraulic rod 34 drives the double-head drilling mechanism 5 to move up and down to perform the drilling operation.

[0056] Before drilling at the right end, the motor 635 drives the positioning column 2 643 to release the lock on the auxiliary support platform 21, and the auxiliary support platform 21 is reset. The rubber plate 632 releases the front and rear clamping of the guide rail, and the guide member 61 maintains the limit on the guide rail to provide guidance for the subsequent movement of the guide rail.
