Description

Technical Field

[0001] The invention belongs to the field of elevator guide rail processing, in particular to a hollow elevator guide rail continuous punching device. Background Art

[0002] Elevator guide rails are elevator components consisting of steel rails and connecting plates, and are divided into car guide rails and counterweight guide rails. They are divided into three types based on the cross-sectional shape: T-shaped, L-shaped, and hollow. Guide rails are generally installed using bolts and other fixings, and professional equipment is required to machine the required bolt holes on the surface of the elevator guide rails.

[0003] During the installation of traditional hollow elevator guide rails, it is necessary to ensure that the punched holes of the elevator guide rails are aligned with the holes reserved in the guide rail brackets. If misalignment occurs, it will cause deviations in the original installation and require multiple adjustments before installation, or even lead to problems with installation. In this case, it is necessary to carve the required punching positions on the surface of the elevator guide rails, and then rely on the operator's operation to ensure the punching positions. This will result in slow punching efficiency and difficulty in ensuring accuracy.

[0004] To this end, the present invention provides a hollow elevator guide rail continuous punching device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve the technical problem is as follows: a hollow elevator guide rail continuous punching device according to the present invention comprises a base, an upper movable seat is arranged above the base, a punching assembly for punching the elevator rail is fixedly connected to the upper movable seat, an electric wheel is arranged on one side of the upper movable seat, the electric wheel is used to fit the elevator rail and drive the elevator rail to move horizontally, and a detection assembly for detecting the moving state of the elevator rail is also arranged on one side of the upper movable seat;

[0007] Preferably, through the setting of the electric wheel, the hollow elevator guide rail that needs to be punched is placed between the upper moving seat and the base, and the electric wheel is pressed on the hollow raised part of the hollow elevator guide rail. Then the electric wheel is driven, and the surface of the base is smooth to reduce friction. Before punching, powder particles that reduce friction can also be sprinkled on the surface of the base. As the electric wheel rotates, the elevator guide rail is driven to move at a uniform speed. The surface of the elevator guide rail needs to first be engraved with the positions of two punching holes, and the elevator guide rail is punched using a punching assembly. After the first position is determined, it is only necessary to control the number of rotations of the electric wheel to control the moving distance of the elevator guide rail. In this way, the moving position of the elevator guide rail can be controlled, and another position that needs to be punched is moved to the punching assembly for punching. Through this setting, it is only necessary to determine the position of the first punching point, and then the elevator guide rail can be controlled to move to a predetermined position by driving the electric wheel. Compared with manual alignment, the mechanical alignment method is more accurate and effectively reduces labor costs. In order to ensure that the driving distance of the electric wheel and the actual movement distance of the elevator track are the same, the detection component further ensures the accuracy of punching.

[0008] Preferably, the base and the upper movable seat are both arranged in sections, the two sections of the base have the same volume, the two sections of the upper movable seat have the same volume, and adjustment components are arranged between the two sections of the base and the two sections of the upper movable seat, and the adjustment components are used to adjust the distance between the two sections of the base and the two sections of the upper movable seat. The structure of the hollow elevator guide rail causes a bulge to exist in its center, and the positions of the punching holes are located on both sides of the bulge. Due to the different widths of different elevator guide rails, in order to improve the scope of application of the device, the adjustment component is arranged to adjust the distance between the two sections of the base and the two sections of the upper movable seat. As the upper movable seat is adjusted, the stamping component is also adjusted along with the upper movable seat, so that elevator guide rails of different widths can be placed in the equipment and punching holes at the required positions can be processed.

[0009] Preferably, the adjusting component includes two hydraulic rods four, which are fixedly connected to the middle part of one opposite side of the two base sections, and the adjusting component also includes two hydraulic rods three, the two ends of the hydraulic rod three are respectively fixedly connected to the top of the two upper movable seats, and the two hydraulic rods three are symmetrically arranged at the center, and a track plate is provided at the bottom of the base, and the base is slidably engaged with the top of the track plate, and a center plate is fixedly connected to the middle part of the track plate, and the ends of the two hydraulic rods four are fixedly connected to the center plate. The gap between the two bases can be adjusted by extending and retracting the hydraulic rod four. When the hydraulic rod four is shortened, the two bases will slide on the track plate, and the two hydraulic rods three and the hydraulic rod four are adjusted synchronously to ensure that the two upper movable seats can also move synchronously. Since the two hydraulic rods three are symmetrically arranged at the center, the pulling force and thrust force on the two upper movable seats during the adjustment process are the same. At the same time, the setting of the center rod is also to ensure the two bases, and finally to ensure that the equipment remains in the middle of the track plate during the adjustment process.

[0010] Preferably, the punching assembly includes two hydraulic rods 2, a protective tube is connected between the top of the hydraulic rods 2 and the base, the two hydraulic rods 2 are respectively vertically fixed in two upper moving seats, the bottom of the hydraulic rods 2 is fixed with a punching head, the inside of the base is fixed with four vertically arranged hydraulic rods 1, the four hydraulic rods 1 are distributed at the four corners of the base, the top of the hydraulic rod 1 and the upper moving seat, the punching head is driven to sink through the hydraulic rods 2, the surface of the elevator rail is squeezed and cut, and the punching is completed. The arrangement of the four hydraulic rods 1 is to decompose the punching process into two stages. The first stage The four hydraulic rods are shortened, driving the upper movable seat to be pressed down as a whole until the punching head contacts the elevator guide rail and stops. Then the hydraulic rod two drives the punching head at the bottom to be pressed down to complete the punching work. Through this setting, the punching process is split. The first stage is used to fix and position the elevator guide rail, and the second stage is used for formal punching. It not only keeps the punching stage stable, but also reduces the hydraulic amplitude of the hydraulic rod two to ensure the thrust of the hydraulic rod two. At the same time, the gap between the base and the upper movable seat can be adjusted, which facilitates the placement process of the elevator guide rail. The inside of the protective tube is used to protect the oil pipe for conveying hydraulic oil and the wires for conveying weak electricity.

[0011] Preferably, two clearance holes adapted to the punching head are provided on the top surface of the base, a hole is provided on the bottom of the punching head, and two symmetrical notches are provided on the bottom of the punching head. The setting of the punching head makes the bottom of the punching head not a complete circle, so that when the punching head starts to punch, the pressure applied to the elevator guide rail will increase because the surface area is reduced. Then, as the punching head continues to penetrate deeper, the punching can be completed. Since the pressure is relatively high at the beginning, the surface of the elevator guide rail can be well damaged. Compared with the traditional round hole punching head, the required force is smaller and the damage to the punching head is also smaller.

[0012] Preferably, a connecting frame is installed on the outer side of the electric wheel, and a rotating shaft is installed between the two ends of the connecting frame and the upper moving seat, and a spring damping rod is arranged between the outer side of the connecting frame and the upper moving seat, and the two ends of the spring damping rod are rotatably connected to the upper moving seat and the connecting frame respectively. The spring damping rod will pull the connecting frame to make the connecting frame tend to a vertical state, so that the electric wheel will always press down, ensuring that no matter how high the elevator guide rail is, the electric wheel will always press on the top of the elevator guide rail. At this time, the electric wheel rotates, which can drive the elevator guide rail to move. At the same time, the electric wheel also fixes the elevator guide rail on the base. During the processing, the upper moving seat is pressed down, and the pressure of the spring damping rod on the elevator guide rail is also increased. Thereby ensuring a stable punching process of the elevator guide rail without manual movement and adjustment.

[0013] Preferably, the outer surface of the electric wheel is made of elastic material, and a plurality of inner grooves are provided on the outer surface of the electric wheel for increasing friction. The surface of the electric wheel squeezes the elevator guide rail, and deforms during the squeezing process to increase the compression area. The inner grooves are used to increase friction to ensure that the electric wheel has sufficient force to push the elevator guide rail.

[0014] Preferably, the detection assembly includes a detection wheel, one end of which is provided with an adjustment frame, the end of which is fixedly connected with a rotation detector, the detection end of which is connected to the detection wheel, and a detection head is installed on the side of the detection wheel facing the elevator guide rail, the detection head is used to emit light and receive the emitted light information. In order to ensure the movement accuracy of the elevator guide rail, the detection wheel is pressed on both sides of the top surface of the elevator guide rail. Whenever the electric wheel rotates to drive the elevator guide rail to move, the detection wheel will passively rotate due to friction, and the number of rotations will be detected and analyzed by the rotation detector to obtain the displacement of the elevator guide rail. The drive of the moving wheel is preset to ensure that the displacement of the elevator guide rail each time is the preset value. In order to reduce errors, the detection wheel also detects the actual movement value of the elevator guide rail. When the actual value is the same as the preset value, it means that the equipment is operating normally. When they are not equal, the electric wheel stops working to prevent the punching position from deviating. At the same time, in order to ensure the accuracy of the detection data, the detection head will emit a detection laser toward the middle side of the elevator guide rail. After the laser is emitted, it is received by the detection part of the detection head. The principle is similar to the optical detection part at the bottom of the mouse. Mechanical detection and optical detection are carried out simultaneously to ensure the accuracy of the detection.

[0015] Preferably, a sliding seat is provided above the adjusting frame, the sliding seat is fixedly connected to the outer side of the upper moving seat, a sliding groove is provided at the bottom of the sliding seat, a screw nut mechanism is installed in the sliding groove, the moving end of the screw nut mechanism is connected to the adjusting frame, the setting of the sliding seat allows the positions of the adjusting frame and the detection wheel to be adjusted to adapt to elevator guide rails of different widths, ensuring that the detection wheel will not be blocked by the middle of the elevator guide rail, the screw nut mechanism can control the horizontal movement of the adjusting frame and has a self-locking function, so that the adjusting frame cannot move by itself, and the adjusted end of the detection wheel fits into the middle of the elevator guide rail and is close to one side, ensuring that the laser of the detection head can be emitted normally.

[0016] Preferably, an adjusting telescopic rod is fixedly connected to the top of the adjusting frame, and a rotating shaft 2 is connected to the top of the adjusting telescopic rod and the movable end of the screw nut mechanism. The adjusting frame is arranged in a bent shape, and the rotating shaft 2 allows the adjusting frame to be flipped upward to facilitate the loading of the elevator guide rail. A spring is built into the adjusting telescopic rod to ensure that the detection wheel fits the elevator guide rail. At the same time, when the upper moving seat is pressed down, the adjusting telescopic rod is shortened and will not affect the normal working of the detection parts below.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The hollow elevator guide rail continuous punching device described in the present invention, through the setting of the electric wheel, puts the hollow elevator guide rail to be punched between the upper moving seat and the base, presses the electric wheel on the hollow raised part of the hollow elevator guide rail, and then drives the electric wheel. The surface of the base is smooth to reduce friction. Before punching, powder particles that reduce friction can also be sprinkled on the surface of the base. As the electric wheel rotates, the elevator guide rail is driven to move at a uniform speed. The surface of the elevator guide rail needs to be engraved with the positions of two punching holes first, and the elevator guide rail is punched using a punching assembly. After the first position is determined, By simply controlling the number of rotations of the electric wheel, the moving distance of the elevator guide rail can be controlled, so that the moving position of the elevator guide rail can be controlled, and another position that needs to be punched can be moved to the stamping assembly for stamping. Through this setting, only the position of the first punching point needs to be determined, and then the elevator guide rail can be controlled to move to the predetermined position through the drive of the electric wheel. Compared with manual alignment, mechanical alignment is more accurate and effectively reduces labor costs. In order to ensure that the driving distance of the electric wheel and the actual movement distance of the elevator rail are the same, the detection component further ensures the accuracy of punching.

[0019] 2. The present invention describes a hollow elevator guide rail continuous punching device, the structure of the hollow elevator guide rail leads to a bulge in the center thereof, and the punching holes are located on both sides of the bulge. Since different elevator guide rails have different widths, in order to improve the application range of the device, an adjustment component is provided to adjust the distance between the two sections of the base and the two sections of the upper movable seat. As the upper movable seat is adjusted, the punching component is also adjusted along with the upper movable seat, so that elevator guide rails of different widths can be placed in the device and punching holes at the required positions can be processed.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] like Figures 1 to 3 As shown, a hollow elevator guide rail continuous punching device according to an embodiment of the present invention comprises a base 2, an upper movable seat 5 is arranged above the base 2, a punching assembly for punching the elevator rail is fixedly connected to the upper movable seat 5, an electric wheel 8 is arranged on one side of the upper movable seat 5, the electric wheel 8 is used to fit the elevator rail and drive the elevator rail to move horizontally, and a detection assembly for detecting the moving state of the elevator rail is also arranged on one side of the upper movable seat 5;

[0030] Traditional punching equipment is generally equipped with only a support table and a hydraulic punching module. Generally, the required punching positions need to be engraved on the surface of the elevator guide rail, and then the punching positions are guaranteed by the operator. This will result in slow punching efficiency and difficulty in ensuring accuracy.

[0031] Through the setting of the electric wheel 8, the hollow elevator guide rail that needs to be punched is placed between the upper moving seat 5 and the base 2, and the electric wheel 8 is pressed on the hollow raised part of the hollow elevator guide rail. Then the electric wheel 8 is driven, and the surface of the base 2 is a smooth plane to reduce friction. Before punching, powder particles that reduce friction can also be sprinkled on the surface of the base 2. As the electric wheel 8 rotates, the elevator guide rail is driven to move at a uniform speed. The surface of the elevator guide rail needs to first depict the positions of two punching holes. The elevator guide rail is punched using a punching assembly. After the first position is determined, it is only necessary to control the number of rotations of the electric wheel 8 to control the moving distance of the elevator guide rail. In this way, the moving position of the elevator guide rail can be controlled, and another position that needs to be punched is moved to the punching assembly for punching. Through this setting, it is only necessary to determine the position of the first punching point. Subsequently, the elevator guide rail can be controlled to move to a predetermined position by driving the electric wheel 8. Compared with manual alignment, the mechanical alignment method is more accurate and effectively reduces labor costs. In order to ensure that the driving of the electric wheel 8 and the actual moving distance of the elevator track are the same, the detection component further ensures the accuracy of punching.

[0032] like Figures 1 to 3As shown, the base 2 and the upper movable seat 5 are both arranged in sections, the two sections of the base 2 have the same shape, the two sections of the upper movable seat 5 have the same shape, and an adjustment component is arranged between the two sections of the base 2 and the two sections of the upper movable seat 5, and the adjustment component is used to adjust the distance between the two sections of the base 2 and the two sections of the upper movable seat 5;

[0033] During operation, there is a protrusion in the structural center of the hollow elevator guide rail, and the punching positions are located on both sides of the protrusion. Due to the different widths of different elevator guide rails, in order to improve the applicability of the device, an adjustment component is provided to adjust the distance between the two sections of the base 2 and the two sections of the upper movable seat 5. As the upper movable seat 5 is adjusted, the punching component is also adjusted along with the upper movable seat 5, so that elevator guide rails of different widths can be placed in the equipment and punching holes at the required positions can be processed.

[0034] like Figures 1 to 3 As shown, the adjustment component includes two hydraulic rods four 12, the ends of the two hydraulic rods four 12 are connected to each other, the output ends of the two hydraulic rods four 12 are respectively fixed to the middle of the opposite sides of the two sections of the base 2, the adjustment component also includes two hydraulic rods three 7, the two ends of the hydraulic rods three 7 are respectively fixed to the top of the two upper movable seats 5, the two hydraulic rods three 7 are centrally symmetrically arranged, the bottom of the base 2 is provided with a track plate 1, the base 2 is slidably engaged with the top of the track plate 1, the middle of the track plate 1 is fixed with a center plate, and the ends of the two hydraulic rods four 12 are fixed to the center plate;

[0035] During operation, the gap between the two bases 2 can be adjusted by extending and retracting the hydraulic rod four 12. When the hydraulic rod four 12 is shortened, the two bases 2 will slide relative to each other on the track plate 1, and the two hydraulic rods three 7 and the hydraulic rod four 12 are adjusted synchronously to ensure that the two upper movable seats 5 can also move synchronously. Since the two hydraulic rods three 7 are centrally symmetrically arranged, the tension and thrust forces on the two upper movable seats 5 are the same during the adjustment process. The ends of the two hydraulic rods four 12 are connected to each other, and the output end of the hydraulic rod four 12 is fixed to the base 2. The ends of the two hydraulic rods four 12 are fixed to the center plate at the same time. The setting of the center rod is to ensure that the two bases 2 can slide relative to each other stably, and ultimately to ensure that the equipment remains in the middle of the track plate 1 during the adjustment process.

[0036] like Figures 1 to 3 As shown, the stamping assembly includes two hydraulic rods 26, a protective tube 3 is connected between the top of the hydraulic rods 26 and the base 2, the two hydraulic rods 26 are respectively vertically fixed in two upper movable seats 5, the bottom of the hydraulic rods 26 is fixed with a punching head 10, and four vertically arranged hydraulic rods 14 are fixed inside the base 2, the four hydraulic rods 14 are distributed at the four corners of the base 2, and the top of the hydraulic rods 14 is fixed with the upper movable seat 5;

[0037] During operation, the punch head 10 is driven to sink through the hydraulic rod 26 to punch holes on the two sides of the elevator track. The setting of the hydraulic rod 14 can decompose the punching process into two stages. In the first stage, the four hydraulic rods 14 are shortened to drive the upper movable seat 5 to press down as a whole until the punch head 10 contacts the elevator guide rail and stops. Then the hydraulic rod 26 drives the bottom punch head 10 to press down to complete the punching work. This setting can split the punching process. The first stage is used to fix and position the elevator guide rail, and the second stage is used for formal punching. It not only keeps the punching stage stable, but also reduces the hydraulic amplitude of the hydraulic rod 26 to ensure the thrust of the hydraulic rod 26. At the same time, the gap between the base 2 and the upper movable seat 5 can be adjusted, which facilitates the insertion process of the elevator guide rail; the protective tube 3 is used to protect the oil pipe for conveying hydraulic oil and the wires for conveying weak electricity.

[0038] like Figures 1 to 6 As shown, two clearance holes 11 adapted to the punch head 10 are provided on the top surface of the base 2, a hole is provided at the bottom of the punch head 10, and two symmetrical notches are provided at the bottom of the punch head 10;

[0039] During operation, the punch head 10 is set so that the bottom of the punch head 10 is not a complete circle. In this way, when the punch head 10 starts to punch, the pressure applied to the elevator guide rail will increase due to the reduction in surface area; then, as the punch head 10 continues to penetrate deeper, the punching can be completed. Since the pressure is relatively high at the beginning, the surface of the elevator guide rail can be well damaged. Compared with the traditional round hole punch head 10, the force required is smaller and the damage to the punch head 10 is also smaller.

[0040] like Figures 1 to 6 As shown, a connecting frame 15 is installed on the outer side of the electric wheel 8, a rotating shaft 13 is installed between the two ends of the connecting frame 15 and the upper moving seat 5, a spring damping rod 14 is arranged between the outer side of the connecting frame 15 and the upper moving seat 5, and the two ends of the spring damping rod 14 are rotatably connected to the upper moving seat 5 and the connecting frame 15 respectively;

[0041] During operation, the spring damping rod 14 keeps the electric wheel 8 in a downwardly pressed state. No matter what the height of the elevator guide rail is, the electric wheel 8 will always be pressed on the top of the elevator guide rail. At this time, the electric wheel 8 rotates to drive the elevator guide rail to move. At the same time, the electric wheel 8 also fixes the elevator guide rail on the base 2. During the processing, the upper moving seat 5 is pressed downward. At this time, the pressure of the spring damping rod 14 on the elevator guide rail is also increased, thereby ensuring a stable punching process of the elevator guide rail without manual movement and adjustment.

[0042] like Figures 1 to 6As shown, the outer surface of the electric wheel 8 is made of elastic material, and a plurality of inner grooves are provided on the outer surface of the electric wheel 8 for increasing friction. When working, the surface of the electric wheel 8 squeezes the elevator guide rail, and deforms during the squeezing process to increase the compression area. The inner grooves are used to increase friction to ensure that the electric wheel 8 has sufficient force to push the elevator guide rail.

[0043] like Figures 1 to 6 As shown, the detection assembly includes a detection wheel 9, an adjustment frame 16 is provided at one end of the detection wheel 9, a rotation detector is fixedly connected to the end of the adjustment frame 16, and the detection end of the rotation detector is connected to the detection wheel 9. A detection head 22 is installed on the side of the detection wheel 9 facing the elevator guide rail, and the detection head 22 is used to emit light and receive reflected light information;

[0044] During operation, in order to ensure the movement accuracy of the elevator guide rail, the detection wheel 9 is pressed on both sides of the top surface of the elevator guide rail. Whenever the electric wheel 8 rotates to drive the elevator guide rail to move, the detection wheel 9 will passively rotate due to friction, and the number of rotations will be detected and analyzed by the rotation detector to obtain the displacement of the elevator guide rail. For different types of elevator guide rails, the staff first presets the corresponding driving stroke of the electric wheel 8. In order to reduce errors, the detection wheel 9 detects the actual moving stroke of the elevator guide rail. When the actual moving stroke is the same as the preset driving stroke, it means that the equipment is operating normally. When they are not equal, the electric wheel 8 stops working to prevent deviations in the punching position. At the same time, in order to ensure the accuracy of the detection data, the detection head 22 will emit a detection laser toward one side of the middle of the elevator guide rail. The laser is reflected and received by the detection part of the detection head 22. The detection principle of the detection head 22 is similar to the optical detection part at the bottom of the mouse. The mechanical detection of the detection wheel 9 and the optical detection of the detection head 22 are carried out simultaneously to ensure the accuracy of the detection.

[0045] like Figures 1 to 6 As shown, a sliding seat 19 is provided above the adjustment frame 16, and the sliding seat 19 is fixedly connected to the outer side of the upper moving seat 5. A sliding groove is provided at the bottom of the sliding seat 19, and a screw nut mechanism 20 is installed in the sliding groove. The moving end of the screw nut mechanism 20 is connected to the adjustment frame 16;

[0046] During operation, the setting of the sliding seat 19 allows the positions of the adjustment frame 16 and the detection wheel 9 to be adjusted to adapt to elevator guide rails of different widths, ensuring that the detection wheel 9 will not be blocked by the protrusion in the middle of the elevator guide rail. The screw nut mechanism 20 can control the horizontal movement of the adjustment frame 16 and has a self-locking function, so that the adjustment frame 16 cannot move by itself. The end of the adjusted detection wheel 9 fits the middle of the elevator guide rail to one side, ensuring that the laser of the detection head 22 can normally emit and receive reflected signals.

[0047] like Figures 1 to 6As shown, the top of the adjustment frame 16 is fixedly connected with an adjustment telescopic rod 17, the top of the adjustment telescopic rod 17 and the moving end of the screw nut mechanism 20 are connected with a rotating shaft 2 18, and the adjustment frame 16 is arranged in a bent shape;

[0048] During operation, the rotating shaft 18 allows the adjustment frame 16 to flip upward to facilitate the loading of the elevator guide rail. The adjustment telescopic rod 17 has a built-in spring to ensure that the detection wheel 9 fits the elevator guide rail. At the same time, when the upper moving seat 5 is pressed down, the adjustment telescopic rod 17 is shortened, which will not affect the normal work of the detection parts below.

[0049] During operation, the hollow elevator guide rail to be punched is placed between the upper moving seat 5 and the base 2 through the setting of the electric wheel 8, and the electric wheel 8 is pressed on the hollow raised part of the hollow elevator guide rail. Then the electric wheel 8 is driven, and the surface of the base 2 is smooth to reduce friction. Before punching, powder particles that reduce friction can also be sprinkled on the surface of the base 2. As the electric wheel 8 rotates, the elevator guide rail is driven to move at a uniform speed. The surface of the elevator guide rail needs to be engraved with the positions of two punching holes first, and the elevator guide rail is punched using the punching assembly. After the first position is determined, it is only necessary to control the electric wheel The number of rotations of 8 can control the moving distance of the elevator guide rail, so that the moving position of the elevator guide rail can be controlled, and another position that needs to be punched can be moved to the stamping component for punching. Through this setting, it is only necessary to determine the position of the first punching point, and then the elevator guide rail can be controlled to move to the predetermined position through the drive of the electric wheel 8. Compared with manual alignment, the mechanical alignment method is more accurate and effectively reduces the labor cost. In order to ensure that the driving distance of the electric wheel 8 is the same as the actual moving distance of the elevator track, the detection component further ensures the accuracy of punching;

[0050] The structure of the hollow elevator guide rail results in a bulge in the center of the guide rail, and the punching holes are located on both sides of the bulge. Since different elevator guide rails have different widths, in order to improve the application range of the device, an adjustment component is provided to adjust the distance between the two sections of the base 2 and the two sections of the upper movable seat 5. As the upper movable seat 5 is adjusted, the punching component is also adjusted along with the upper movable seat 5, so that elevator guide rails of different widths can be placed in the device and punching holes at the required positions can be processed;

[0051] The gap between the two bases 2 can be adjusted by extending and retracting the hydraulic rod four 12. When the hydraulic rod four 12 is shortened, the two bases 2 will slide on the track plate 1. The two hydraulic rods three 7 and the hydraulic rod four 12 are adjusted synchronously to ensure that the two upper movable seats 5 can also move synchronously. Since the two hydraulic rods three 7 are centrally symmetrically arranged, the tension and thrust of the two upper movable seats 5 are the same during the adjustment process. At the same time, the setting of the center rod is also to ensure the two bases 2, and finally ensure that the equipment remains in the middle of the track plate 1 during the adjustment process.

[0052] The punching head 10 is driven to sink by the hydraulic rod 26 to squeeze and cut the surface of the elevator rail to complete the punching. The four hydraulic rods 14 are set up to decompose the punching process into two stages. In the first stage, the four hydraulic rods 14 are shortened to drive the upper movable seat 5 to press down as a whole until the punching head 10 contacts the elevator guide rail and stops. Then the hydraulic rod 26 drives the bottom punching head 10 to press down to complete the punching work. This setting splits the punching process. The first stage is used to fix and position the elevator guide rail, and the second stage is used for formal punching. It not only keeps the punching stage stable, but also reduces the hydraulic amplitude of the hydraulic rod 26 to ensure the thrust of the hydraulic rod 26. At the same time, the gap between the base 2 and the upper movable seat 5 can be adjusted, which facilitates the placement process of the elevator guide rail; the interior of the protective tube 3 is used to protect the oil pipe for conveying hydraulic oil and the wires for conveying weak electricity;

[0053] The arrangement of the punch head 10 makes the bottom of the punch head 10 not a complete circle, so that when the punch head 10 starts to punch, the pressure applied to the elevator guide rail will increase because the surface area is reduced. Then, as the punch head 10 continues to penetrate, the punching can be completed. Since the pressure is relatively high at the beginning, the surface of the elevator guide rail can be well damaged. Compared with the traditional round hole punch head 10, the force required is smaller and the damage to the punch head 10 is also smaller;

[0054] The spring damping rod 14 will pull the connecting frame 15, so that the connecting frame 15 tends to a vertical state, so that the electric wheel 8 will always press down, ensuring that no matter how high the elevator guide rail is, the electric wheel 8 will always press on the top of the elevator guide rail. At this time, the electric wheel 8 rotates, which can drive the elevator guide rail to move. At the same time, the electric wheel 8 also fixes the elevator guide rail on the base 2. During the processing, the upper moving seat 5 is pressed down. At this time, the pressure of the spring damping rod 14 on the elevator guide rail is also increased, thereby ensuring a stable punching process of the elevator guide rail without manual movement and adjustment;

[0055] The surface of the electric wheel 8 squeezes the elevator guide rail, and deforms during the squeezing process to increase the pressing area. The inner groove is used to increase the friction force to ensure that the electric wheel 8 has enough force to push the elevator guide rail;

[0056] In order to ensure the movement accuracy of the elevator guide rail, the detection wheel 9 is pressed on both sides of the top surface of the elevator guide rail. Whenever the electric wheel 8 rotates to drive the elevator guide rail to move, the detection wheel 9 will rotate passively due to friction. The number of rotations will be detected and analyzed by the rotation detector to obtain the displacement of the elevator guide rail. The drive of the electric wheel 8 is preset to ensure that the displacement of the elevator guide rail each time is the preset value. In order to reduce errors, the detection wheel 9 also detects the actual movement value of the elevator guide rail. When the actual value is the same as the preset value, it means that the equipment is operating normally. When they are not equal, the electric wheel 8 stops working to prevent the punching position from deviating. At the same time, in order to ensure the accuracy of the detection data, the detection head 22 will emit a detection laser toward one side of the middle of the elevator guide rail. After the laser is diverged, it is received by the detection part of the detection head 22; the principle is similar to the optical detection part at the bottom of the mouse. Mechanical detection and optical detection are carried out simultaneously to ensure the accuracy of the detection;

[0057] The setting of the sliding seat 19 allows the positions of the adjustment frame 16 and the detection wheel 9 to be adjusted, so as to adapt to elevator guide rails of different widths, ensuring that the detection wheel 9 will not be blocked by the middle of the elevator guide rail. The screw nut mechanism 20 can control the horizontal movement of the adjustment frame 16 and has a self-locking function, so that the adjustment frame 16 cannot move by itself. The end of the detection wheel 9 after adjustment is close to the middle of the elevator guide rail and close to one side, ensuring that the laser of the detection head 22 can be emitted normally;

[0058] The rotating shaft 18 allows the adjustment frame 16 to flip upward to facilitate the loading of the elevator guide rail. The adjustment telescopic rod 17 has a built-in spring to ensure that the detection wheel 9 fits the elevator guide rail. At the same time, when the upper moving seat 5 is pressed down, the adjustment telescopic rod 17 is shortened without affecting the normal work of the detection parts below.
