[0003] Currently, refer to Figure 1 The guide rail includes a mounting plate 46 and a convex strip 47 fixedly arranged in the middle of the mounting plate 46. The top surface of the mounting plate 46 has a certain inclination. The mounting plate 46 is inclined downward by 3-8 degrees along its width direction toward both sides away from the convex strip 47 to form an inclined top surface. Four mounting holes 48 are symmetrically opened on the mounting plate 46 on both sides of the convex strip 47. Each group of four mounting holes 48 is formed. Multiple groups of mounting holes 48 are opened on the guide rail at equal intervals along its length direction. Bolts are passed through the mounting holes 48 and fixed to the supports on the shaft wall, so that the guide rail can be fixedly installed on the shaft wall.

In the present application, the second driving member 31 can be selected as a servo motor, and the second driving member 31 drives the plurality of conveying rollers 33 to rotate synchronously through a transmission chain.

[0041] Four mounting brackets 25 are fixedly mounted on each bracket 32. A side wheel 29 is rotatably mounted on the bottom of each mounting bracket 25 near the side of the conveying roller 33 with the vertical direction as the rotation axis. A pressure wheel 10 is rotatably mounted on the top of each two mounting brackets 25 with the horizontal direction as the rotation axis. The pressure wheel 10 abuts against the top wall of the guide rail convex strip 47, and the two side wheels 29 abut against the two side walls of the guide rail mounting plate 46 in the width direction. The guide rail is placed on the conveying roller 33, and the second driving member 31 drives the conveying roller 33 to rotate and convey the guide rail. During the conveying process of the guide rail, the pressure wheel 10 and the side wheel 29 guide the movement of the guide rail, so that the guide rail can be accurately moved to the bottom of the drilling mechanism 2.

[0042] Reference Figure 2 and Figure 3 The drilling mechanism 2 includes a lifting component 21, a lifting seat 22, four first driving components 23 and a drill rod 24.

In the present application, the lifting component 21 can be selected as a motor screw as a driving source, and the first driving component 23 can be selected as a servo motor.

[0043] When the guide rail moves to below the lifting seat 22 , the lifting component 21 drives the lifting seat 22 to move downward, the lifting seat 22 drives the four first driving members 23 to move downward, the first driving members 23 drive the drill rods 24 to rotate, and the four drill rods 24 drill four mounting holes 48 on the guide rail mounting plate 46 at the same time.

[0044] A mounting seat 11 is fixedly installed on the base 1, and the mounting seat 11 is located directly below the lifting seat 22. A support block 6 is placed in the middle of the top wall of the mounting seat 11. Two trigger rods 8 are fixedly installed on the bottom of the connecting plate 35. The two trigger rods 8 are both installed in the vertical direction. The two trigger rods 8 are located on both sides of the support block 6 along the conveying direction of the guide rail, and a first accommodating groove 36 for accommodating the trigger rod 8 is opened on the top wall of the mounting seat 11 directly below the two trigger rods 8.

[0045] Reference Figure 3 , Figure 4 and Figure 5The mounting seat 11 is provided with a driving mechanism 9, which includes two first push rods 91, a first elastic reset member 92, four second push rods 93 and a second elastic reset member 94. The two first push rods 91 are slidably mounted on the top wall of the mounting seat 11 along the width direction of the guide rail, and the two first push rods 91 are located on both sides of the support block 6 along the length direction of the guide rail. The mounting seat 11 is provided with a first baffle 37 fixedly mounted on one end of each first push rod 91 away from the trigger rod 8, and the first elastic reset member 92 is mounted between the first baffle 37 and the end of the first push rod 91.

[0046] The bottom end of the trigger rod 8 and the end of the first push rod 91 are both set to be wedge-shaped. When the lifting component 21 drives the drill rod 24 to move downward, the lifting component 21 can drive the two first push rods 91 to slide on the mounting seat 11 toward the first baffle 37 through the two trigger rods 8. The first push rod 91 moves and squeezes the first elastic reset member 92.

[0047] The four second push rods 93 are all slidably mounted on the top wall of the mounting seat 11 along the length direction of the guide rail. Two first wedge-shaped grooves 12 are provided on the side walls of the two first push rods 91 close to each other. Two second wedge-shaped grooves 13 are provided on the bottom wall of the support block 6 on both sides close to the first push rods 91. Both ends of the second push rod 93 are wedge-shaped, and the two ends of the second push rod 93 are respectively located in the first wedge-shaped groove 12 and the second wedge-shaped groove 13. A sliding groove 14 connected to the second wedge-shaped groove 13 is provided on the bottom wall of the support block 6. A second baffle 38 is fixedly mounted on the side wall of each second push rod 93. Four third baffles 39 are fixedly mounted on the top wall of the mounting seat 11. The third baffle 39 is located on the side of the second baffle 38 close to the support block 6, and the two ends of the second elastic reset member 94 are respectively connected to the second baffle 38 and the third baffle 39. In the present application, both the first elastic reset member 92 and the second elastic reset member 94 can be selected as springs.

[0048] When the first push rods 91 slide, the two first push rods 91 push the four second push rods 93 to move synchronously toward the support block 6 through the first wedge-shaped grooves 12, and the four second push rods 93 push the support block 6 upward through the second wedge-shaped grooves 13 during the movement. When one end of the second push rod 93 moves from the second wedge-shaped groove 13 into the sliding groove 14, the top wall of the support block 6 moves to press against the bottom wall of the guide rail mounting plate 46. At this time, the support block 6 cooperates with the pressure wheel 10 to limit the guide rail along the height direction of the guide rail, making the guide rail drilling process more stable and improving the accuracy of the guide rail drilling.

[0049] When the support block 6 moves downward, the first elastic reset member 92 pushes the first push rod 91 to move and reset, and the second elastic reset member 94 pushes the second push rod 93 to move and reset through the second baffle 38, so that the end of the second push rod 93 enters the first wedge-shaped groove 12 again.

[0050] Reference Figure 3 Four avoidance holes 7 are spaced apart in the middle of the top wall of the support block 6, and the four avoidance holes 7 correspond to the four mounting holes 48 of the guide rail. When the drill rod 24 drills the guide rail, the drill rod 24 will extend into the avoidance holes 7 of the support block 6, so that the drill rod 24 will not interfere with the support block 6.

The four third elastic reset members 42 are all installed in the support block 6 and are located on the side of the fourth push rod 43 away from the third push rod 41. In the present application, the third elastic reset member 42 can be selected as a spring.

[0053] When the top wall of the support block 6 abuts against the bottom wall of the guide rail, the second push rod 93 slides into the sliding groove 14, and the second push rod 93 pushes the third push rod 41 to move toward the support block 6, and the third push rod 41 pushes the fourth push rod 43 to move toward the guide rail.

The third push rod 41 drives the wedge-shaped push block 40 to move together and abut against the wedge-shaped surface of the fourth push rod 43, so that the fourth push rod 43 can move and abut against the guide rail more effectively. When the support block 6 moves downward, and the second elastic reset member 94 drives the second push rod 93 to move and reset, the third elastic reset member 42 pushes the fourth push rod 43 to move and reset, and the fourth push rod 43 pushes the third push rod 41 to move and reset through the wedge-shaped surface, and the fourth push rod 43 abuts against the abutment plate 44 after being reset.

[0058] The tension spring 55 drives the slide bar 51 to move in the opposite direction of the guide rail conveying through the pull rod, and the slide bar 51 drives the lifting plate 53 and the fourth second latch 58 to move toward the support block 6 through the lifting rod 52. The sliding sleeve 521 moves onto the lifting rod 18 through the wedge-shaped end, and the lifting rod 18 pushes the sliding sleeve 521 to move upward, and the sliding sleeve 521 drives the retaining ring 17 to move upward and squeeze the first elastic member 56. At this time, the first elastic member 56 is in an elastically compressed state, and the first elastic member 56 acts on the second latch 58 through the lifting plate 53, so that the top end of the second latch 58 is pressed against the bottom wall of the guide rail.

[0059] When the guide rail is drilled and the conveying mechanism 3 conveys the guide rail, when the installation hole 48 of the guide rail moves to above the four second latches 58, the first elastic member 56 pushes the four second latches 58 upward through the lifting plate 53 and inserts them into the four installation holes 48. At this time, the slide bar 51 can be driven to move by the second latches 58, and the first elastic member 56 returns to a normal state.

[0060] When the slide bar 51 drives the lifting rod 52 to move away from the support block 6, the slide sleeve 521 moves on the lifting rod 18. When the slide sleeve 521 moves out of the lifting rod 18, the third elastic member 16 pulls the slide sleeve 521 downward through the retaining ring 17, and the retaining ring 17 pulls the first elastic member 56 to extend, so that the first elastic member 56 is in a stretched state. Since the tension spring 55 has a pulling force on the slide bar 51, the static friction between the second latch 58 close to the support block 6 and the guide rail mounting hole 48 increases. At this time, the static friction between the second latch 58 and the mounting hole 48 is greater than the pulling force of the first elastic member 56, and the second latch 58 will not be separated from the mounting hole 48.

[0061] The slide bar 51 is provided with a slot 15, and the first latch 54 is slidably mounted on the top wall of the support block 6 in the vertical direction, and the top end of the first latch 54 extends above the support block 6, and the first latch 54 is located above the slide bar 51. The second elastic member 57 is sleeved on the first latch 54 and is located in the support block 6, and a push ring 34 is fixedly mounted on the latch, and the top end of the second elastic member 57 is fixedly connected to the push ring 34, and the bottom end is fixedly connected to the support block 6. In the present application, the second elastic member 57 can be selected as a spring.

[0062] When the guide rail is transported, the slide bar 51 drives the slot 15 to move below the first latch 54. The support block 6 moves upward, and the support block 6 drives the retaining ring 17 to move upward through the slide bar 51, and the first elastic member 56 returns to a normal state. The support block 6 drives the first latch 54 to move upward, and the top of the first latch 54 moves to abut the bottom wall of the guide rail. As the support block 6 continues to rise, the first latch 54 is gradually inserted into the slot 15. At this time, the side wall of the first latch 54 close to the second latch 58 is pressed against the inner wall of the slot 15, so that the slide bar 51 can be driven to move slightly toward the second latch 58, reducing the static friction between the side of the second latch 58 close to the support block 6 and the mounting hole 48. The first latch 54 is inserted into the slot 15, thereby limiting the slide bar 51, and the slide bar 51 limits the guide rail along the length direction of the guide rail through the lifting rod 52, the lifting plate 53 and the four second latches 58, so that the guide rail drilling process is more stable and the accuracy of the guide rail drilling is improved.

[0063] When the guide rail is finished drilling and the support block 6 moves downward, the support block 6 drives the retaining ring 17 to move downward through the slide bar 51, and the retaining ring 17 pulls the first elastic member 56 to extend. At this time, the pulling force of the first elastic member 56 is greater than the static friction between the second latch 58 and the mounting hole 48, so that the second latch 58 can be pulled out of the mounting hole 48. At the same time, during the downward movement of the support block 6, the second elastic member 57 pushes the first latch 54 to move upward through the push ring 34. When the first latch 54 is disengaged from the slot 15 of the slide bar 51, the tension spring 55 pulls the slide bar 51 to move and reset, and the slide bar 51 pulls the sliding sleeve 521 to move to the lifting rod 18 again, so that the four second latches 58 can be inserted into the mounting hole 48 of the guide rail again.

[0064] A rounded corner 20 is formed at the bottom end of the first plug 54 and at a side close to the second plug 58. When the first plug 54 is inserted into the slot 15, the rounded corner 20 of the first plug 54 facilitates the first plug 54 to abut against the inner wall of the slot 15 near the side wall of the second plug 58. A rounded chamfer 19 is formed at the top end of the second plug 58. The rounded corner 20 at the top end of the second plug 58 facilitates the second plug 58 to be inserted into and slide out of the mounting hole 48 of the guide rail.

[0065] The implementation principle of the elevator guide rail drilling device of the embodiment of the present application is as follows: the guide rail is placed on the conveying roller 33, the second driving member 31 drives the conveying roller 33 to rotate and convey the guide rail, and during the conveying process of the guide rail, the pressure wheel 10 and the side wheel 29 guide the movement of the guide rail so that the guide rail can be accurately moved to the bottom of the drilling mechanism 2. When the guide rail moves to the bottom of the lifting seat 22, the lifting member 21 drives the lifting seat 22 to move downward, the lifting seat 22 drives the four first driving members 23 to move downward, the first driving member 23 drives the drill rod 24 to rotate, and the four drill rods 24 drill four mounting holes 48 on the guide rail mounting plate 46 at the same time.

[0066] When the lifting component 21 drives the drill rod 24 to move downward, the lifting component 21 can drive the two first push rods 91 to slide on the mounting seat 11 toward the first baffle 37 through the two trigger rods 8, and the first push rods 91 move and squeeze the first elastic reset member 92. When the first push rods 91 slide, the two first push rods 91 push the four second push rods 93 to move synchronously toward the support block 6 through the first wedge groove 12, and the four second push rods 93 push the support block 6 upward through the second wedge groove 13 during the movement. When one end of the second push rod 93 moves from the second wedge groove 13 into the sliding groove 14, the top wall of the support block 6 moves to press against the bottom wall of the guide rail mounting plate 46. At this time, the support block 6 cooperates with the pressure wheel 10 to limit the guide rail along the height direction of the guide rail, so that the guide rail drilling process is more stable and the accuracy of the guide rail drilling is improved.

[0067] When the top wall of the support block 6 abuts against the bottom wall of the guide rail, the second push rod 93 slides into the sliding groove 14, and the second push rod 93 pushes the third push rod 41 to move toward the support block 6, and the third push rod 41 pushes the fourth push rod 43 to move toward the guide rail. The four fourth push rods 43 move along the width direction of the guide rail and abut against the opposite side walls of the guide rail mounting plate 46, so that the guide rail can be limited along the width direction of the guide rail, making the guide rail drilling process more stable and improving the accuracy of the guide rail drilling.

[0068] When the guide rail is transported, the slide bar 51 drives the slot 15 to move below the first latch 54. The support block 6 moves upward, and the support block 6 drives the retaining ring 17 to move upward through the slide bar 51, and the first elastic member 56 returns to a normal state. The support block 6 drives the first latch 54 to move upward, and the top of the first latch 54 moves to abut the bottom wall of the guide rail. As the support block 6 continues to rise, the first latch 54 is gradually inserted into the slot 15. At this time, the side wall of the first latch 54 close to the second latch 58 is pressed against the inner wall of the slot 15, so that the slide bar 51 can be driven to move slightly toward the second latch 58, reducing the static friction between the side of the second latch 58 close to the support block 6 and the mounting hole 48. The first latch 54 is inserted into the slot 15, thereby limiting the slide bar 51, and the slide bar 51 limits the guide rail along the length direction of the guide rail through the lifting rod 52, the lifting plate 53 and the four second latches 58, so that the guide rail drilling process is more stable and the accuracy of the guide rail drilling is improved.

For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
