Description

Technical Field

[0001] This invention pertains to the field of railway sleeper manufacturing. More specifically, this invention relates to an automatic demolding and conveying device and method for a railway sleeper production line. Background Technology

[0002] Railway sleepers, also known as railway sleepers, are a type of railway component. However, the materials used are not limited to wood, so calling them railway sleepers is more accurate. Nowadays, reinforced concrete sleepers are commonly used. These sleepers are produced by placing steel bars inside a steel mold, pouring in concrete to form the sleeper, and then removing the finished sleeper from the mold.

[0003] Patent publication number CN117381965A discloses an automatic demolding and conveying device for railway sleeper production, including a support base. One end of the support base is equipped with a flipping base plate, and a guide box is connected to the flipping base plate. A vibration demolding assembly is located on top of the guide box. During demolding, the production mold is placed upside down within the space enclosed by a lifting limit frame and an annular support plate. A rotating cam continuously pushes a vibrating horizontal plate upwards. Each time the vibrating horizontal plate rises, it lifts the placed production mold along with it. The mold then falls back down onto the guide box due to gravity, generating vibration for demolding. The demolded sleeper falls onto a conveyor plate inside the guide box, and then the conveyor plate slides down under gravity, detaching from the guide box. The sleeper is then tilted and conveyed onto a conveyor belt assembly, thus completing the automatic demolding and conveying process without manual handling, improving the convenience of the demolding operation. While this patent application achieves automatic demolding of railway sleepers, it does not include the flipping of the sleeper mold, resulting in a lower degree of automation in the demolding process. Summary of the Invention

[0004] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0005] One objective of this invention is to provide an automatic demolding and conveying device for a railway sleeper production line, which can realize the flipping and conveying of railway sleeper molds, thereby improving the demolding efficiency of railway sleeper molds.

[0006] To achieve these objectives and other advantages of the present invention, an automatic demolding and conveying device for a railway sleeper production line is provided, comprising:

[0007] The sleeper mold conveyor belt is inclined.

[0008] The flipping structure includes a flipping motor, a flipping device, a conveyor roller, and a buffer device. The flipping device is rotatably mounted on a support, and the flipping motor is fixedly mounted on the support. The flipping device is inclined at the end of the sleeper mold conveyor belt, and the bottom of the flipping groove of the flipping device is opposite to the position of the sleeper mold conveyor belt. The flipping motor is connected to the flipping device to flip the flipping device by 180°. The conveyor roller is located below the flipping device, and the buffer device is located below the flipping device and between the conveyor rollers.

[0009] Preferably, the tilting trough includes a support plate and a vertical plate, with the vertical plate vertically arranged on the support plate to make the tilting trough have an L-shaped structure, and the horizontal part of the L-shape of the tilting trough is on the same plane as the sleeper mold conveyor belt.

[0010] Preferably, the two ends of the flipping groove are provided with side plates, and a first limiting member and a second limiting member are provided above the side plates. After the sleeper mold moves to the flipping groove, the first limiting member abuts against the upper end of the sleeper mold to limit the sleeper mold in the flipping groove when the flipping groove flips. The second limiting member abuts against the sleeper in the sleeper mold to limit the sleeper in the sleeper mold when the flipping groove flips.

[0011] Preferably, the first limiting member and the second limiting member are telescopic devices.

[0012] Preferably, the buffer device includes an oil tank, a fixed cylinder, and a telescopic cylinder. The telescopic cylinder is slidably fitted inside the fixed cylinder. The oil tank is connected to the fixed cylinder. The oil tank, the fixed cylinder, and the telescopic cylinder are filled with hydraulic oil. The oil tank is equipped with an oil pressure device to pressurize the hydraulic oil in the oil tank to the telescopic cylinder and the fixed cylinder.

[0013] Preferably, the oil pressure device includes:

[0014] The piston is located in the oil tank;

[0015] A spring, one end of which is connected to the piston and the other end of which is connected to the wall of the oil tank;

[0016] The spring is in a compressed state to press the hydraulic oil in the oil tank into the telescopic cylinder and the fixed cylinder, so that the telescopic cylinder is higher than the conveying roller.

[0017] Preferably, a roller is provided at the top of the telescopic cylinder.

[0018] Preferably, it further includes a positioning device, the positioning device comprising:

[0019] The first adjusting roller is located at the end of the conveying roller;

[0020] The first adjusting component is disposed on both sides of the first adjusting roller and has a figure-eight structure. The end of the first adjusting component with a larger opening is opposite to the position of the conveying roller.

[0021] The second adjusting roller is located at the end of the second adjusting roller;

[0022] The second adjusting component is disposed on both sides of the second adjusting roller and is arranged parallel to each other.

[0023] Preferably, it also includes a sleeper mold transfer device, the sleeper mold transfer device comprising:

[0024] A frame is disposed on the side of the flip structure;

[0025] A sliding structure, which is slidably mounted on the frame;

[0026] Transfer rollers are disposed below the frame;

[0027] A support structure is provided below the sliding structure and offset from the transfer roller. The support structure includes a vertical part and a horizontal part. The vertical part of the support structure is fixedly connected to the sliding structure. The vertical part of the support structure is a lifting device. The horizontal part of the support structure is fixedly connected to the vertical part of the support structure to form an L-shaped structure. The horizontal part of the support structure is higher than the conveying roller.

[0028] A method for demolding and transferring railway sleepers using an automated demolding and conveying equipment on a railway sleeper production line includes the following steps:

[0029] 1) Transfer the sleeper that needs to be demolded to the sleeper mold conveyor belt. The sleeper mold moves downward under the action of the sleeper mold conveyor belt and its own gravity and enters the turning groove. The first limiting member extends to limit the sleeper mold in the turning groove, and the second limiting member extends and limits the sleeper mold in the sleeper mold.

[0030] 2) The flipping motor flips the flipping groove 180°, the second limit piece retracts, the sleeper falls out of the sleeper mold onto the buffer device, the flipping motor resets to prepare for the next sleeper flipping, the buffer device moves downward under the weight of the sleeper, the sleeper contacts the conveying roller, the conveying roller transports the sleeper to the adjustment device to adjust the sleeper's posture in preparation for the sleeper to be transferred to the support plate.

[0031] 3) After the sleeper detaches from the sleeper mold, the sliding structure moves to the side of the flipping structure so that the horizontal part of the supporting structure is below the sleeper mold. The first limiting member retracts, the sleeper mold falls on the horizontal part of the supporting structure, the sliding structure moves away from the flipping structure and is above the transfer roller, the vertical part of the supporting structure descends to a height lower than the transfer roller, the transfer roller supports the sleeper mold and moves the sleeper mold away, and the vertical part of the supporting structure rises to prepare for the next transfer of the sleeper mold.

[0032] The present invention has at least the following beneficial effects:

[0033] First, this invention utilizes a flipping structure to flip the sleeper mold, thereby separating the sleeper mold from the sleeper. An adjusting device is used to adjust the sleeper's posture so that the sleeper is aligned with the external support plate, facilitating the transfer of the sleeper to the placement slot on the support plate. A sleeper mold transfer device is used to transfer the sleeper mold from the flipping structure, thus achieving automatic separation and conveying of the sleeper mold from the sleeper.

[0034] Secondly, the present invention sets the sleeper mold conveyor belt and the flipping structure at an angle, which can make full use of the inertial force of the sleeper during movement to achieve the flipping of the sleeper, which helps to reduce the output torque of the flipping motor and reduce equipment requirements and energy consumption.

[0035] Third, after the sleeper detaches from the telescopic cylinder, the buffer device of the present invention requires a certain amount of time for the hydraulic oil in the oil tank to enter the fixed cylinder and the telescopic cylinder, and therefore the telescopic cylinder needs a certain amount of time to reset upwards. This provides time for the sleeper mold transfer device to transfer the sleeper mold, and avoids the telescopic cylinder interfering with the movement of the sleeper mold transfer device.

[0036] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0045] like Figure 1-4 As shown, the present invention provides an automatic demolding and conveying device for a railway sleeper 7 production line, comprising:

[0046] The sleeper mold conveyor belt (not shown in the figure) is inclined.

[0047] The flipping structure includes a flipping motor, a flipping device 1, a conveying roller 2, and a buffer device 3. The flipping device 1 is rotatably mounted on a support 4, and the flipping motor is fixedly mounted on the support 4. The flipping device 1 is inclined at the end of the sleeper mold conveyor belt, and the bottom of the flipping groove of the flipping device 1 is opposite to the position of the sleeper mold conveyor belt. The flipping motor is connected to the flipping device 1 to flip the flipping device 1 by 180°. The conveying roller 2 is located below the flipping device 1, and the buffer device 3 is located below the flipping device 1 and is located between the conveying rollers 2.

[0048] In this technical solution, the maximum tilt angle of the sleeper mold conveyor belt is preferably such that the sleeper mold does not slide relative to the conveyor belt, preferably 10-20°. The sleeper mold conveyor belt can adopt the transmission structure disclosed in patent publication number CN219381018U to achieve continuous shaking during the conveying of the sleeper mold, separating the sleeper 7 from the sleeper mold, so as to facilitate the subsequent detachment of the sleeper 7 from the sleeper mold. The sleeper molds are placed at intervals on the sleeper mold conveyor belt to provide time for the flipping structure to flip, that is, the time taken for the flipping structure to flip and reset is less than the time it takes for the next sleeper mold to move to the flipping device 1. Several conveying rollers 2 can be equally spaced below the flipping device 1, and the axial direction of the conveying rollers 2 is perpendicular to the length direction of the sleeper mold, that is, the length direction of the sleeper 7. The buffer device can be a hydraulic buffer or a spring 87 buffer. The height of the buffer device 3 is higher than that of the conveying rollers 2. The buffer device 3 moves downward under the gravity of the sleeper 7. When the sleeper 7 abuts against the conveying rollers 2, the conveying rollers 2 play the role of supporting and conveying the sleeper 7.

[0049] The method of using the equipment of this invention is as follows: After the sleeper maintenance is completed, the sleeper in the sleeper mold is transferred to the conveyor belt. At this time, the opening of the sleeper mold is facing upward. The conveyor belt transports the sleeper mold to the flipping structure. The flipping motor drives the flipping device to rotate 180° so that the opening of the sleeper mold faces downward. The flipping device releases the sleeper. Under its own gravity, the sleeper detaches from the sleeper mold and falls onto the buffer device. The weight of the sleeper is greater than the buffering force of the buffer device, so the sleeper slowly descends and contacts the conveying roller. The conveying roller transports the sleeper to the next component.

[0050] This invention tilts the sleeper mold conveyor belt and the flipping structure, fully utilizing the inertial force of the sleeper during movement to achieve its flipping. This helps reduce the output torque of the flipping motor, lowering equipment requirements and energy consumption. Furthermore, this invention enables automatic flipping and conveying of the sleeper mold, improving the automation level of the sleeper production line.

[0051] In another technical solution, the tilting trough includes a support plate 11 and a vertical plate 12. The vertical plate 12 is vertically mounted on the support plate 11 to make the tilting trough have an L-shaped structure. The horizontal part of the L-shape of the tilting trough is on the same plane as the sleeper mold conveyor belt. The support plate 11 is rotatably hinged to the bracket 4. When the sleeper 7 slides onto the support plate 11, the vertical plate 12 prevents the sleeper mold from detaching from the support plate 11. A positioning sensor can be installed on the vertical plate 12. When the sleeper mold abuts against the positioning sensor, the tilting motor drives the tilting trough to tilt downwards along the movement direction of the sleeper mold.

[0052] In another technical solution, side plates 13 are provided at both ends of the tilting groove, and a first limiting member 14 and a second limiting member 15 are provided above the side plates 13. After the sleeper mold moves into the tilting groove, the first limiting member 14 abuts against the upper end of the sleeper mold to limit the sleeper mold in the tilting groove when it tilts, and the second limiting member 15 abuts against the sleeper 7 in the sleeper mold to limit the sleeper 7 in the sleeper mold when it tilts. The side plates 13 on the tilting groove can serve to limit the sleeper mold. In some other technical solutions, the side plates 13 may be omitted, and the first limiting member 14 and the second limiting member 15 may be provided on the upright plate 12.

[0053] In another technical solution, the first limiting member 14 and the second limiting member 15 are telescopic devices. The telescopic device can be a pneumatic rod or a hydraulic rod.

[0054] In another technical solution, the buffer device 3 includes an oil tank 81, a fixed cylinder 83, and a telescopic cylinder 82. The telescopic cylinder 82 is slidably fitted inside the fixed cylinder 83. The oil tank 81 and the fixed cylinder 83 are connected by an oil pipe 85. The oil tank 81, the fixed cylinder 83, and the telescopic cylinder 82 are filled with hydraulic oil. An oil pressure device is provided in the oil tank 81 to pressurize the hydraulic oil in the oil tank 81 to the telescopic cylinder 82 and the fixed cylinder 83. When the sleeper mold presses down on the buffer device 3, the telescopic cylinder 82 and the fixed cylinder 83 are sealed together by a sealing ring, and the hydraulic oil in the fixed cylinder 83 and the telescopic cylinder 82 enters the oil tank 81. After the sleeper mold is removed from the buffer device 3, the oil pressure device presses the hydraulic oil in the oil tank into the fixed cylinder 83 and the telescopic cylinder 82. In some technical solutions, a regulating valve 84 can be provided at the connection between the oil tank 81 and the fixed cylinder 83 to control the hydraulic oil flow rate. The regulating valve 84 is used to adjust the hydraulic oil flow rate to adjust the lifting and lowering rate of the telescopic cylinder 82. Each fixed cylinder 83 and telescopic cylinder 82 can be equipped with an oil tank 81.

[0055] In another technical solution, the oil pressure device includes:

[0056] Piston 86, which is located in oil tank 81;

[0057] Spring 87, one end of which is connected to piston 86, and the other end of which is connected to the wall of oil tank 81;

[0058] The spring 87 is in a compressed state to press the hydraulic oil in the oil tank 81 into the telescopic cylinder 82 and the fixed cylinder 83, so that the telescopic cylinder 82 is higher than the conveying roller 2.

[0059] Under the weight of the sleeper 7, the telescopic cylinder 82 moves downward, thereby pressing the hydraulic oil into the oil tank 81. At this time, the spring 87 is further compressed. After the sleeper 7 is separated from the telescopic cylinder 82, the spring 87 compresses the hydraulic oil in the oil tank 81 into the fixed cylinder 83 and the telescopic cylinder 82.

[0060] In another technical solution, a roller is provided on the top of the telescopic cylinder 82. By providing the roller, the sliding friction between the bottom of the sleeper 7 and the telescopic cylinder 82 is changed to rolling friction, reducing the resistance to the movement of the sleeper 7.

[0061] In another technical solution, a positioning device 5 is also included, the positioning device 5 comprising:

[0062] The first adjusting roller 51 is located at the end of the conveying roller 2;

[0063] The first adjusting member 52 is disposed on both sides of the first adjusting roller 51 and has a figure-eight structure. The end of the first adjusting member 52 with a larger opening is opposite to the position of the conveying roller 2.

[0064] The second adjusting roller 53 is disposed at the end of the second adjusting roller 53;

[0065] The second adjusting member 54 is disposed on both sides of the second adjusting roller 53 and is arranged parallel to each other.

[0066] The adjusting device 5 of this technical solution can adjust the posture of the sleeper 7 to be opposite to the placement groove on the external support plate, so as to facilitate the placement of the sleeper 7 in the placement groove. For example, the support plate adopts the structure disclosed in patent publication number CN117445170A. The first adjusting component 52 and the second adjusting component 54 can be adjusting transmission belts, the belt movement direction is the same as the movement direction of the sleeper 7, and the belt surface of the transmission belt is perpendicular to the plane where the first adjusting roller 51 is located.

[0067] In another technical solution, a sleeper mold transfer device 6 is also included, the sleeper mold transfer device 6 comprising:

[0068] Frame 61 is disposed on the side of the flip structure;

[0069] A sliding structure is slidably mounted on the frame 61;

[0070] Transfer roller 62 is disposed below the frame 61;

[0071] A supporting structure 63 is disposed below the sliding structure and offset from the transfer roller 62. The supporting structure 63 includes a vertical part 631 and a horizontal part 632. The vertical part of the supporting structure 63 is fixedly connected to the sliding structure. The vertical part 631 of the supporting structure 63 is a lifting device. The horizontal part 632 of the supporting structure is fixedly connected to the vertical part 631 of the supporting structure to form an L-shaped structure. The horizontal part 632 of the supporting structure is higher than the conveying roller. After the sleeper 7 is detached from the sleeper mold, the sliding structure moves towards the flipping structure to move the horizontal part 632 of the supporting structure 63 below the sleeper mold. The first limiting member 14 actuates to cause the sleeper mold to detach from the flipping groove and fall onto the horizontal part 632 of the supporting structure 63. The sliding structure moves above the transfer roller 62, the vertical part 631 of the supporting structure 63 descends, the transfer roller 62 transfers the sleeper mold, and the supporting structure 63 resets. The vertical part 631 of the supporting structure 63 can be a hydraulic telescopic rod, an actuating telescopic rod, etc. In some technical solutions, the horizontal part 632 of the supporting structure 63 can be lower than the height of the telescopic cylinder 82 when it is fully extended. The flow rate of hydraulic oil is adjusted by the regulating valve 84 to achieve the purpose of the telescopic cylinder 82 rising slowly, so as to provide time for the transfer device to transfer the sleeper mold. That is, when the sleeper mold transfer device 6 has completely completed the transfer of the sleeper mold, the telescopic cylinder 82 has not yet extended upward to touch the sleeper mold.

[0072] The method for demolding and transferring railway sleeper 7 using an automatic demolding and conveying equipment includes the following steps:

[0073] 1) Transfer the sleeper 7 that needs to be demolded to the sleeper mold conveyor belt. The sleeper mold moves downward under the action of the sleeper mold conveyor belt and its own gravity and enters the turning groove. The first limiting member 14 extends to limit the sleeper mold in the turning groove, and the second limiting member 15 extends to limit the sleeper mold in the sleeper mold.

[0074] 2) The flipping motor flips the flipping groove 180°, the second limiting piece 15 retracts, and the sleeper 7 falls out of the sleeper mold onto the buffer device 3. The buffer device 3 moves downward under the gravity of the sleeper 7, and the sleeper 7 contacts the conveying roller 2. The conveying roller 2 conveys the sleeper 7 to the adjusting device 5 to adjust the posture of the sleeper 7 in preparation for the transfer of the sleeper 7 to the support plate.

[0075] 3) After the sleeper 7 is detached from the sleeper mold, the sliding structure moves to the side of the flipping structure so that the horizontal part 632 of the supporting structure 63 is below the sleeper mold. The first limiting member 14 retracts, and the sleeper mold falls on the horizontal part 632 of the supporting structure 63. The sliding structure moves away from the flipping structure and is located above the transfer roller 62. The vertical part 631 of the supporting structure 63 descends to a height lower than the transfer roller 62. The transfer roller 62 supports the sleeper mold and moves the sleeper mold away. The vertical part 631 of the supporting structure 63 rises to prepare for the next transfer of the sleeper mold. The flipping motor resets to prepare for the next flipping of the sleeper 7.

[0076] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
