Description

Technical Field

[0001] This invention belongs to the field of train wheel equipment. Specifically, this invention relates to a train wheel stack correction device and a wheel stack transfer method. Background Technology

[0002] With the increasing demand for train wheel production, the requirements for production processes and equipment are also constantly rising. Train wheel heat treatment is a key process that involves precisely controlling the heating and cooling process to adjust the metallographic structure of the wheel, thereby obtaining the required hardness, toughness, wear resistance, and dimensional stability, ensuring the long-term safe service of the wheel under high-speed and heavy-load conditions. It usually requires 2 to 3 heat treatments and is typically performed in a multi-line heat treatment system. After heat treatment, the train wheel needs to be transferred to a slow cooling chamber for slow cooling treatment, so that the train wheel cools down slowly and evenly, controls residual stress, prevents cracking and deformation, and ensures the stability of the wheel's mechanical properties.

[0003] Therefore, the positioning requirements for the transport loader are constantly increasing. When coordinating materials from multiple heat treatment lines and slow-cooling silos, the materials need to be first unloaded into the loader's production area. However, the following problems exist: External wheels are transported by trucks, unloaded by forklifts and placed on ground saddles outside the fence on the east side of the silo area, and then hoisted into the saddle by the transport loader. However, because the stacks of external wheel loads on the ground saddle are not neatly stacked, when the transport loader hoists them into the saddle in the loader's production area, the hook wheels often tip over during the process of the lifting claws opening and detaching from the wheel stacks, damaging the lifting equipment and saddle, posing a significant equipment safety risk. Simultaneously, the train wheels hoisted into the production area are often not placed correctly, making it easy for the robotic arm to grip them crookedly. This results in the train wheels being improperly loaded into the furnace, and when they are taken out of the furnace and placed on the quenching platform, they are prone to tipping over, requiring manual straightening. This increases the labor intensity of the workers, and the overlapping operations of workers and the transport loader create significant safety hazards.

[0004] Therefore, in order to improve or solve at least one of the above problems, a train wheel stack alignment device and wheel stack transfer method are provided, which can correct the position of train wheel stacks, meet the positioning requirements of the transport loader, solve the problem of misalignment of upper and lower layers of wheels in the external material stack, avoid the problem of hook wheel overturning and damage to lifting tools and saddles during hoisting, avoid wheel overturning during quenching, and help reduce the labor intensity of workers.

Detailed Implementation

[0017] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0018] Figure 1 This is a schematic diagram of the structure of the train wheel stacking correction device in an embodiment of the present invention.

[0019] like Figure 1As shown, the train wheel stack alignment device provided by the present invention includes a base plate 10, a saddle 20, a clamping fixture 30, and a clamping drive unit 40. The saddle 20 is set on the base plate 10, and the wheel stacks 1 are stacked on the saddle 20. The clamping fixture 30 is located on both sides of the saddle 20. The clamping drive unit 40 is set on the base plate 10 and connected to the clamping fixture 30. The clamping drive unit 40 can drive the clamping fixture 30 to center and clamp the wheel stacks 1 on the saddle 20, and correct the position of the train wheel stacks. This solves the problem of misalignment of the upper and lower layers of wheels in the external material stacks, thereby meeting the positioning accuracy requirements of the loader. It can avoid the problem of hook wheels tipping over and damaging the lifting equipment and saddle during the hoisting process, and can avoid wheel tipping during the quenching process, which helps to reduce the labor intensity of the workers.

[0020] Figure 2 This is a schematic diagram of the saddle structure in an embodiment of the present invention.

[0021] like Figure 2 As shown, the saddle 20 includes a support plate 21, a support plate 22, and a pad 23. The support plate 21 is set on the base plate 10, and the support plate 22 is set on the support plate 21 to improve the load-bearing capacity and stability of the saddle 20. The pad 23 is set on the support plate 22, and the wheel stack 1 is located on the pad 23. The pad 23 is placed in a "Y" shape on the support plate 22 to support the wheel stack 1, which facilitates the stacking of the wheel stack 1 and the installation of the lifting device and the gripping of the robot during subsequent hoisting.

[0022] Figure 3 This is a schematic diagram of the clamping fixture in an embodiment of the present invention. Figure 1 ; Figure 4 This is a schematic diagram of the clamping fixture in an embodiment of the present invention. Figure 2 .

[0023] like Figure 3 and Figure 4As shown, the clamping fixture 30 includes a clamping plate 31 and clamping rods 32. The clamping plate 31 is V-shaped in horizontal cross-section, adapted to the outer edge of the train wheel. The inner side of the clamping plate 31 fits against the curved surface of the outer edge of the wheel, which can increase the clamping contact area, avoid excessive local stress and damage to the wheel body, and automatically calibrate the wheel stack center through the "centering effect" of the "V" shaped surface to ensure accurate centering. The clamping rods 32 are set in the vertical direction, and two clamping rods 32 are respectively set on both sides of the clamping plate 31. The clamping rods 32 abut against the outer edge of the train wheel. The clamping fixtures 30 on both sides of the wheel stack 1 move closer to each other. As the clamping fixtures 30 continue to move closer, the "V" shaped surface on the clamping plate 31 guides the clamping mechanism through the fit. The offset wheel stack 1 is gradually guided to the correct position, and eventually all of them are calibrated to the symmetrical center of the clamping fixtures 30 on both sides. The clamping rods 32 on both sides abut against the upper and lower wheels of the wheel stack 1. The centering accuracy of the wheel stack 1 reaches the preset value, with a center deviation of ≤5mm. This achieves alignment between the center of the wheel stack 1 and the center of the saddle 20, enabling automatic centering of wheel stacks 1 at heights of 1m to 1.5m. This solves the problem of misalignment of upper and lower wheels in the external material wheel stack, thus meeting the positioning accuracy requirements of the loader. It can prevent the hook wheel from tipping over and damaging the lifting equipment and saddle during the lifting process, and can prevent the wheels from tipping over during the quenching process, which helps to reduce the labor intensity of the workers.

[0024] like Figure 3 and Figure 4 As shown, the clamping fixture 30 also includes a support column 33, a side plate 34, and an upper plate 35. The support column 33 is connected to the clamping drive unit 40. One side edge of the side plate 34 is connected to the support column 33, and the other side edge of the side plate 34 is connected to the clamping plate 31. One side edge of the upper plate 35 is connected to the support column 33, and the other side edge of the upper plate 35 is connected to the clamping plate 31. This realizes the connection between the clamping fixture 30 and the clamping drive unit 40, improves the structural strength of the clamping fixture 30, and ensures the clamping fixture 30's resistance to bending and torsion.

[0025] The side plate 34 is provided with reinforcing ribs 341, which are evenly distributed on the side plate 34 and connected to the clamping rod 32; the upper plate 35 is provided with reinforcing ribs 351, which are connected to the clamping rod 32. By setting the reinforcing ribs 341 and reinforcing ribs 351, the structural strength of the clamping fixture 30 is further improved, ensuring the bending and torsion resistance of the clamping fixture 30, so that the clamping plate 31 and the support column 33 form a rigid whole without loosening, ensuring that the wheel stack 1 will not wobble or shake during the centering clamping process, and ensuring the centering accuracy of the wheel stack 1.

[0026] Figure 5 This is a schematic diagram of the clamping drive unit in an embodiment of the present invention.

[0027] like Figure 5 As shown, the clamping drive unit 40 includes a lead screw assembly 41, a slide block 42, and a drive assembly 43. The lead screw assembly 41 is mounted on the base plate 10, and the slide block 42 is movably mounted on the lead screw assembly 41. The support column 33 is vertically mounted on the slide block 42 in the vertical direction. The drive assembly 43 is mounted on the base plate 10 and is connected to the lead screw assembly 41. The drive assembly 43 drives the slide block 42 to move through the lead screw assembly 41, so that the clamping clamps 30 on both sides of the wheel stack 1 move closer to each other, thereby achieving centering and clamping of the wheel stack 1 on the saddle 20, correcting the position of the train wheel stack, solving the problem of misalignment of the upper and lower layers of the external material wheel stack, thus meeting the positioning accuracy requirements of the transport loader, avoiding the problem of hook wheel overturning and damage to the lifting equipment and saddle during the hoisting process, and preventing wheel overturning during the quenching process, which helps to reduce the labor intensity of the workers. The base plate 10 is provided with guide rails 11, which are located on both sides of the slide block 22. The guide rails 11 are provided with guide grooves 12 that are adapted to the slide block 22. The two sides of the slide block 22 are slidably disposed in the guide grooves 12, so that the slide blocks 22 can move closer or further apart smoothly and stably. Figure 6 This is a schematic diagram of the lead screw assembly in an embodiment of the present invention.

[0028] like Figure 6 As shown, the lead screw assembly 41 includes a first lead screw 411, a first lead screw bearing housing 412, a second lead screw 413, a second lead screw bearing housing 414, a drive shaft 415, a first coupling 416, and a second coupling 417. The end of the first lead screw 411 is movably inserted into the first lead screw bearing housing 412, which is mounted on the base plate 10. The end of the second lead screw 413 is movably inserted into the second lead screw bearing housing 414, which is mounted on the base plate 10. Two first couplings 416 are respectively mounted at both ends of the drive shaft 415. Both ends of the drive shaft 415 are connected to the first lead screw 411 and the second lead screw 413 respectively through the first coupling 416. The end of the first lead screw 411 away from the drive shaft 415 is connected to the drive assembly 43 through the second coupling 417. The screw threads on the first lead screw 411 and the second lead screw 413 are in opposite directions. The two slides 22 are movably connected to the first lead screw 411 and the second lead screw 413 respectively through threaded engagement, so that the two slides 22 can move closer to or further away from each other, thereby centering and clamping the wheel stack 1 on the saddle 20 and correcting the position of the train wheel stack.

[0029] The drive assembly 43 includes a drive motor 431 and a reducer 432. The reducer 432 is mounted on the base plate 10, and its output shaft is connected to the second coupling 417. The drive motor 431 is mounted on the reducer 432, and its motor shaft is connected to the input shaft of the reducer 432. The drive motor 431 has a power of 3 kW and a thrust of up to 5 tons. The sliding speed of the slide 22 is 1 m / min, which makes the wheel stack 1 position correction process take less than one minute, thereby further improving production and transfer efficiency.

[0030] The saddle 20 can be equipped with a sensor switch to detect whether train wheels are stacked on it. The train wheel stack alignment device also has a three-color alarm light. When the sensor switch on the saddle 20 indicates an empty state, the three-color alarm light turns green, indicating that material can be loaded. The train wheels are placed on the saddle 20 by a crane. After the crane loads the material, it moves the lifting claw away from the alignment device to a safe distance. The operator then clicks the loading completion button, the three-color alarm light turns red, and the clamp drive unit 40 can then activate the mechanism. The clamping fixture 30 clamps and centers the wheel stack 1 on the saddle 20. The clamping fixtures 30 on both sides move towards the middle, pushing the wheel stack 1 to center. When the thrust reaches a certain value, the detection switch is activated, the clamping fixtures 30 on both sides reset, and a centering completion signal is issued. The three-color alarm light turns yellow, and the transport loader can lift the material. The transport loader lifts the wheel stack 1 after the position is corrected to the saddle in the warehouse area. The transport loader lifts it into the warehouse and transfers the wheel stack 1 to the production warehouse area.

[0031] This invention also provides a wheel stack transfer method based on the above-mentioned train wheel stack alignment device, comprising the following steps: Step S1, the train wheels are transferred from outside the storage area to the saddle 20 by a crane, and the train wheels are hoisted from the ground outside the fence on the east side of the production storage area to the saddle 20 of the train wheel stack alignment device; Step S2, the clamping drive unit 40 drives the clamping clamp 30 to center and clamp the wheel stack 1 on the saddle 20, and the clamping clamps 30 on both sides move towards the middle, pushing the wheel stack 1 to center, thereby achieving the centering and alignment of the wheel stack 1. After the alignment is completed, the transport loader hoists the wheel stack 1 into the production storage area; Step S3, the robot arm grabs the train wheels in the production storage area for furnace loading, completing the subsequent production. The wheel stack transfer method based on the above-mentioned train wheel stack alignment device provided by this invention can avoid problems such as hook wheel tipping, damage to the lifting equipment and saddle during hoisting, prevent train wheels from being loaded incorrectly in the furnace, and prevent wheel tipping during quenching, thus reducing the labor intensity of workers.

The saddle 20 is set on the base plate 10, and the wheel stacks 1 are stacked on the saddle 20. The clamping fixture 30 is located on both sides of the saddle 20. The clamping drive unit 40 is set on the base plate 10 and connected to the clamping fixture 30. The clamping drive unit 40 can drive the clamping fixture 30 to center and clamp the wheel stacks 1 on the saddle 20, thereby correcting the position of the train wheel stacks. This solves the problem of misalignment of the upper and lower layers of wheels in the external material stacks, thus meeting the positioning accuracy requirements of the loader. It can avoid the problem of hook wheels tipping over and damaging the lifting equipment and saddle during the lifting process, and can avoid wheel tipping during the quenching process, which helps to reduce the labor intensity of the workers.

[0033] This invention also provides a wheel stack transfer method based on the above-mentioned train wheel stack alignment device, comprising the following steps: Step S1, the train wheels are transferred from outside the storage area to the saddle 20 by a crane, and the train wheels are hoisted from the ground outside the fence on the east side of the production storage area to the saddle 20 of the train wheel stack alignment device; Step S2, the clamping drive unit 40 drives the clamping clamp 30 to center and clamp the wheel stack 1 on the saddle 20, and the clamping clamps 30 on both sides move towards the middle, pushing the wheel stack 1 to center, thereby achieving the centering and alignment of the wheel stack 1.
