Example 1

[0035] The present application embodiment discloses a sleeper demoulding and laser cutting device with monitoring function, referring to Figure 1 and Figure 2, including a conveying frame 1 that is a rectangular parallelepiped as a whole, a plurality of conveying rollers 2 are evenly arranged on the conveying frame 1 along the length direction of the conveying frame 1, the spacing between adjacent conveying rollers 2 is less than the length of a single rail sleeper, an elastic rubber sleeve 20 is sleeved on the conveying roller 2, and a plurality of conveying rollers 2 are synchronously rotated in the same direction by a single motor, gears and a synchronous chain, and a demolding frame 4 is arranged at both ends of the conveying frame 1 near the width direction, and the demolding frame 4 is fixedly mounted on the conveying frame 1 through a support rod 3 arranged on the conveying frame 1, and the demolding frame 4 is mounted above the conveying roller 2, and a conveyor belt 5 is arranged on the demolding frame 4, and the conveyor belt 5 is driven by a stepping motor along The conveying frame 1 is transported in the length direction, and a plurality of door frames 6 are mounted on the conveying frame 1. The plurality of door frames 6 are evenly arranged along the length direction of the conveying frame 1. A laser cutting assembly 7 is arranged on the door frame 6. A long strip casting mold 8 is placed on the demoulding frame 4. The casting mold 8 includes a mold body 81 and a cover plate 82. The mold body 81 is mounted and placed on two demoulding frames 4. The conveyor belt 5 is driven by a stepper motor to drive the mold body 81 to slide along the length direction of the conveying frame 1 on the demoulding frame 4. A mold cavity 9 is opened on the mold body 81 toward the conveying roller 2. The mold cavity 9 is a cavity for casting and forming a plurality of sleepers at the same time. The mold body 81 is reduced by integrally forming a plurality of sleepers. The number of times of placing and calibrating the steel cage is reduced, and the production efficiency of the sleeper is improved. A plurality of mold cavities 9 are opened on the mold body 81, and the plurality of mold cavities 9 are evenly distributed along the width direction of the mold body 81. The setting of multiple mold cavities 9 can increase the output of sleepers for a single demoulding and cutting, thereby further improving the production efficiency. In this embodiment, two mold cavities 9 are set, and a cover plate 82 is set at the opening of the mold cavity 9. A plurality of positioning points 10 are set at one end of the mold body 81 away from the cover plate 82. In this embodiment, the positioning point 10 is a cylindrical block protruding from the mold body 81. The positioning point 10 is mirrored on both sides of the two sleeper cutting positions. The gantry 6 is provided with a laser Monitoring components 11 are mirror-imaged on both sides of the cutting component 7. The monitoring component 11 includes a camera 111. Several positioning points 10 form a group of two, and each group of two positioning points 10 is located on both sides of the cutting position. The spacing between each group of two positioning points 10 is the same as the spacing between the monitoring components 11 on both sides of the laser cutting component 7. The casting mold 8 is transported by the conveyor belt 5, so that the camera 111 monitors the positioning point 10 and then calibrates and stops the transportation of the casting mold 8. Thereafter, the cast sleeper is demoulded by removing the cover plate 82, so that no calibration is required during laser cutting, thereby improving the production efficiency of the sleeper.

[0036] Reference Figure 2 and Figure 3The cover plate 82 includes a shaping plate 821 and a fixing plate 822, both of which are covered on the mold body 81, and a fixing rod 12 is provided on the fixing plate 822 facing the mold body 81, and the fixing rod 12 penetrates the mold body 81, and a fixing mechanism 13 is circumferentially provided at one end of the fixing rod 12 penetrating the mold body 81, and the fixing mechanism 13 includes an abutting rod 131 and an elastic member 132, and the abutting rod 131 is rotatably arranged on the fixing rod 12, and the abutting rod 131 is extended out or received into the fixing rod 12 by rotation, and the elastic member 132 is arranged between the fixing rod 12 and the abutting rod 131, and the elastic member 132 drives the abutting rod 131 to extend out of the fixing rod 12 and abut against one end of the mold body 81 away from the cover plate 82 through elastic force, and the elastic member 132 drives the abutting rod 131 to tilt toward the side away from the mold body 81, and the present embodiment In the example, the elastic member 132 is a spring. When the fixing rod 12 passes through the mold body 81, the mold body 81 abuts against the de-tilted abutting rod 131 to drive the abutting rod 131 to be stored in the fixing rod 12, thereby facilitating the fixing rod 12 to pass through the mold body 81. After the fixing rod 12 passes through the mold body 81, the elastic member 132 drives the abutting rod 131 to extend out and abut against the mold body 81, and the fixing plate 822 is fixed on the mold body 81. The position of the fixing plate 822 is the position where the through hole is opened to fix the track on the sleeper. The fixing rod 12 will not affect the casting of the sleeper and can also facilitate the direct formation of the through hole for fixing the track during casting, without the need for subsequent processing of the through hole. The setting of the fixing plate 822 can reduce the probability of the sleeper detaching from the mold body 81 before the mold body 81 is transported to a suitable demoulding position, and the positioning plate is set to shape the sleeper during casting.

[0037] Reference Figure 1 and Figure 4The monitoring component 11 also includes a driving cylinder 112 arranged on the door frame 6, a mounting platform 113 installed on the driving cylinder 112, and a demolding member 114 fixed on the mounting platform 113 corresponding to the fixed rod 12. In this embodiment, four demolding members 114 are arranged, corresponding to the two mold cavities 9 respectively. The camera 111 is installed at the center of the mounting platform 113. The driving cylinder 112 drives the demolding member 114 to slide toward or away from the fixed rod 12. The inner diameter of the demolding member 114 is the same as the outer diameter of the fixed rod 12. The demolding member 114 is arranged outside the fixed rod 12 through a sliding sleeve. The demolding member 114 slides toward the fixed rod 12 to drive the abutting rod 131 to be stored in the fixed rod. The stripping member 114 includes a mounting rod 1141 fixed on the mounting platform 113, an electromagnetic coil 1142 fixed on one end of the mounting rod 1141 away from the mounting platform 113, a driving magnet 1143 sleeved on the fixed rod 12, and a press switch 1144 fixed on the mounting rod 1141 at the center of the electromagnetic coil 1142. The gravity of the driving magnet 1143 is less than the elastic force of the elastic member 132. The normal elastic member 132 drives the abutment rod 131 to extend out of the fixed rod 12 to drive the driving magnet 1143 to a position that does not affect the expansion of the abutment rod 131. The stripping member 114 slides toward the fixed rod 12 until the electromagnetic coil 1142 is sleeved outside the fixed rod 12. The fixed rod 12 abuts against the push switch 1144. After the push switch 1144 is triggered, the electromagnetic coil 1142 is energized to generate a magnetic field. After the electromagnetic coil 1142 generates a magnetic field, the magnetic pole facing the driving magnet 1143 is the same as the magnetic pole of the driving magnet 1143 facing the electromagnetic coil 1142. The magnetic force generated by the repulsion between the electromagnetic coil 1142 and the driving magnet 1143 plus the gravity of the driving magnet 1143 is greater than the elastic force of the elastic member 132. The driving magnet 1143 is driven to slide and the abutment rod 131 is stored in the fixed rod 12 through the mutually repulsive magnetic force; the conveying roller 2 is provided with an electromagnetic coil. In this embodiment, the casting mold 8 is made of a material that cannot be adsorbed by a magnet. For example, non-magnetic steel, when the fixing plate 822 is separated from the mold body 81, the electromagnetic coil is energized, and due to the presence of the steel cage in the sleeper, the magnetic force will adsorb the sleeper in the mold body 81 to assist the sleeper demoulding; the camera 111 is electrically connected to the control unit; the camera 111 obtains the image before demoulding, which is recorded as the first image; the first image is sent to the control unit; the control unit confirms the position information of the positioning point 10 in the first image based on the first image; the control unit compares the position information of the positioning point 10 with the preset position information to obtain the deviation value between the two; the control unit obtains the adjustment value for controlling the conveyor belt 5 to drive the casting mold 8 to move based on the PID algorithm based on the deviation value;After the conveyor belt 5 controls the casting mold 8 to move to the position corresponding to the adjustment value based on the adjustment value, the control unit controls the driving cylinder 112 to slide so that the electromagnetic coil 1142 is sleeved outside the fixed rod 12, so that the fixed rod 12 triggers the press switch 1144, energizes the electromagnetic coil 1142, and slides the driving magnet 1143 through the magnetic force to push the abutment rod 131 into the fixed rod 12, so that the fixed plate 822 is separated from the casting mold 8, and then the rail sleeper is demoulded. The demoulding member 114 cooperates with the fixed rod 12, which can monitor the positioning accuracy again before demoulding on the one hand, and facilitate the separation of the fixed rod 12 from the mold body 81 on the other hand.

[0038] Reference Figure 1 and Figure 4 An adjusting member 15 is provided between the monitoring component 11 and the gantry 6, and side frames 14 are fixed on both sides of the gantry 6. The adjusting member 15 is installed on the side frames 14. In this embodiment, the adjusting member 15 uses a rodless cylinder, and the driving cylinder 112 is installed on the sliding platform 19 of the rodless cylinder. The adjusting member 15 adjusts the distance between the monitoring component 11 and the laser cutting component 7. The adjusting member 15 is electrically connected to the control unit. The adjusting members 15 on both sides of the laser cutting component 7 are connected to the same control unit. The control unit synchronously drives the two adjusting members 15 to monitor the distance between the cutting point of the laser cutting component 7. The length of the sleepers placed in different geological conditions is different, and the distance from the position where the track is installed on the sleepers to the edge of the sleepers is also different. The setting of the adjusting member 15 can be adjusted according to sleepers of different lengths to improve the applicability of the laser cutting device.

[0039] Reference Figure 2 , Figure 3 and Figure 5 A convex block 16 is detachably provided in the mold cavity 9, and a groove for placing the track is provided on the sleeper. The setting of the convex block 16 can facilitate the integral molding of the groove for placing the track by casting. The detachable convex block 16 can be replaced and adjusted according to the depth requirement of the groove for placing the track. A positioning rod 17 is fixed on the convex block 16, and the positioning rod 17 is inserted into the mold body 81 at the bottom of the mold cavity 9. A plurality of positioning rods 17 are provided, and the number of positioning rods 17 is the same as the number of demoulding parts 114 and is arranged one by one with the demoulding parts 114. In this embodiment, the convex block 16 is provided with a plurality of positioning rods 17, and the number of positioning rods 17 is the same as the number of demoulding parts 114 and is arranged one by one with the demoulding parts 114. Four positioning rods 17 are arranged on 16, and a positioning hole 18 is opened at one end of the positioning rod 17 away from the protrusion 16. The aperture of the positioning hole 18 is the same as the outer diameter of the mounting rod 1141 and the electromagnetic coil 1142. After the sleeper is demoulded, the protrusion 16 is also separated and retained on the sleeper. After the conveyor belt 5 sends away the mold body 81, the cylinder 112 is driven to drive the mounting rod 1141 and the electromagnetic coil 1142 to slide and insert into the positioning hole 18 for re-positioning monitoring. At the same time, it can also reduce the probability of sleeper slippage and reduce the defective rate when cutting the sleeper.

[0040] Reference Figure 1 and Figure 5Sliding tables 19 are placed on the ground at both ends of the conveyor frame 1 in the width direction, and both ends of the gantry 6 are respectively slidably set in the sliding tables 19 at both ends of the conveyor frame 1 in the width direction. Then, the gantry 6 is driven by setting a lead screw or a cylinder to be slidably set on the conveyor frame 1. The gantry 6 slides along the length direction of the conveyor frame 1. The sliding setting of the gantry 6 can appropriately adjust the cutting position according to the length of the mold, so that the processing area is located in the center of the conveyor frame 1, reducing the probability of the conveyor frame 1 tipping over due to uneven force or being damaged due to excessive local force.

[0041] Reference Figure 1 , Figure 4 and Figure 5 The laser cutting assembly 7 includes a horizontal electric cylinder 71, a vertical electric cylinder 72 and a laser cutting machine body 73. The horizontal electric cylinder 71 is a rodless electric cylinder, which is installed on the gantry 6. The vertical electric cylinder 72 is an electric push cylinder, which is installed on the horizontal electric cylinder 71. The horizontal electric cylinder 71 drives the conveying electric cylinder to slide along the width direction of the conveying frame 1. The laser cutting machine body 73 is installed on the vertical electric cylinder 72. The vertical electric cylinder 72 drives the laser cutting machine body 73 to slide toward or away from the conveying roller 2.

[0042] The implementation principle of the embodiment of the present application is as follows: place the mold body 81 with the opening side facing upwards, install the protrusion 16 in the mold body 81, place the steel cage in the mold cavity 9 and calibrate the position of the steel cage before covering the opening side of the mold body 81 with a fixed top plate, then pour concrete in the mold cavity 9, cover the mold cavity 9 with a shaping plate 821 after the concrete fills the mold cavity 9, remove the positioning plate after the concrete solidifies, transfer the mold body 81 upside down to the demoulding frame 4, transport the mold body 81 through the conveyor belt 5, and after the positioning point 10 on the mold body 81 is calibrated with the preset value of the camera 111, drive the demoulding part 114 to slide so that the electromagnetic coil 1142 is sleeved on the fixing rod 12, and the fixing rod 12 triggers the press switch 1144, so that the fixing plate 822 is separated from the mold body 81 and falls from the gap between the conveying rollers 2. In order to facilitate the collection of the fallen The fixed plate 822 can be provided with a conveyor belt under the conveying roller 2 to convey the fixed plate 822 to the outside of the conveying frame 1, and a laser detection device is provided on the conveying frame 1. When the laser detection device detects that the fixed plate 822 has fallen, the electromagnetic coil on the conveying roller 2 assists the sleeper demoulding by generating magnetic force to adsorb the sleeper. After the fixed plate 822 is separated from the mold body 81, the cast sleeper and the protrusion 16 are separated from the mold body 81 at the same time and fall onto the conveying roller 2. Then, the sliding installation rod 1141 is inserted into the positioning hole 18 to reposition and fix the sleeper. The sleeper is cut by the laser cutting assembly 7. After the cutting is completed, the cut sleeper is sent out of the conveying frame 1 through the conveying roller 2. After the protrusion 16 is removed from the sleeper, the sleepers are stacked and stored to complete the processing of the sleeper. Example 2

When the demoulding tube 1145 is sleeved outside the fixed rod 12, the demoulding tube 1145 drives the abutment rod 131 to be stored in the fixed rod 12; after the fixed plate 822 is separated from the mold body 81, the driving cylinder 112 drives the demoulding tube 1145 to slide up and down and vibrate the mold body 81 to assist the demoulding of the sleeper; the camera 111 is electrically connected to the control unit; the camera 111 obtains the image before demoulding, which is recorded as the first image; the first image is sent to the control unit; the control unit confirms the position information of the positioning point 10 in the first image based on the first image; the control unit sends the position information of the positioning point 10 based on the first image The deviation value between the two is obtained by comparing with the preset position information; the control unit obtains the adjustment value for controlling the conveyor belt 5 to drive the casting mold 8 to move based on the deviation value and the PID algorithm; after the conveyor belt 5 controls the casting mold 8 to move to the position corresponding to the adjustment value based on the adjustment value, the control unit controls the driving cylinder 112 to slide so that the demoulding tube 1145 is sleeved outside the fixed rod 12 and the abutment rod 131 is pushed into the fixed rod 12, so that the fixed plate 822 is separated from the casting mold 8, and then the rail sleeper is demoulded. The demoulding part 114 cooperates with the fixed rod 12, so that the positioning accuracy can be monitored again before demoulding on the one hand, and the fixed rod 12 can be easily separated from the mold body 81 on the other hand; the aperture of the positioning hole 18 in this embodiment is the same as the outer diameter of the demoulding tube 1145.

[0045] The implementation principle of the embodiment of the present application is as follows: place the mold body 81 with the opening side facing upwards, install the protrusion 16 in the mold body 81, place the steel cage in the mold cavity 9 and calibrate the position of the steel cage before covering the opening side of the mold body 81 with a fixed top plate, then pour concrete in the mold cavity 9, cover the mold cavity 9 with a shaping plate 821 after the concrete fills the mold cavity 9, remove the positioning plate after the concrete solidifies, transfer the mold body 81 upside down to the demoulding frame 4, convey the mold body 81 through the conveyor belt 5, and after the positioning point 10 on the mold body 81 is calibrated with the preset camera 111, drive the demoulding member 114 to slide so that the demoulding member 114 is sleeved on the fixing rod 12, so that the fixing plate 822 is separated from the mold body 81 and falls from the gap between the conveying rollers 2. In order to facilitate the collection of the fallen A fixed plate 822 can be provided with a conveyor belt under the conveying roller 2 to convey the fixed plate 822 to the outside of the conveying frame 1. After the fixed plate 822 is separated from the mold body 81, the cast sleepers and protrusions 16 are separated from the mold body 81 at the same time and fall onto the conveying roller 2. When the concrete adheres to the mold body 81, it can be demolded by artificially vibrating the mold body 81, or by reciprocating impact of the mold body 81 by the demolding member 114. Then, the demolding member 114 is slid and inserted into the positioning hole 18 to reposition and fix the sleeper. The sleeper is cut by the laser cutting component 7. After the cutting is completed, the cut sleeper is sent out of the conveying frame 1 through the conveying roller 2. After the protrusion 16 is removed from the sleeper, the sleepers are stacked and stored to complete the processing of the sleeper.
