Description

Technical Field

[0001] The utility model relates to the technical field of austenite frog steel casting, in particular to a frog steel reciprocating moving device based on a track. Background Art

[0002] Cast high manganese steel frogs need to be solution treated. There are usually two existing solution treatment methods:

[0003] One method is to lift the frog steel and immerse it in a water tank for solid solution strengthening. When the frog steel is immersed in the water tank, bubbles are easily attached to the surface of the frog steel, which hinders the contact between water and the frog steel and prevents the frog steel from cooling quickly. Moreover, in order to save lifting costs, multiple frog steels are usually stacked together for unified lifting and immersion. There is uneven heat dissipation between the frog steels, and the cooling rate and cooling effect cannot be consistent.

[0004] Another method involves water-spraying solid solution strengthening of the frog steel. This method uses an annular clamping mechanism to hold the frog steel. A nozzle is installed on the clamping mechanism, creating an annular water trough within the clamping mechanism. The nozzle sprays water along the cross-section of a single frog steel. This method avoids bubbles forming on the frog steel surface and eliminates the issue of inconsistent cooling rate and cooling effect. However, this method prevents the frog steel from being exposed to water at the clamping position, resulting in uneven cooling and prone to bending deformation. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a track-based reciprocating moving device for frog steel, which can be used in conjunction with traditional water spray type solid solution strengthening equipment. When the frog steel is solid solution strengthened, the frog steel can be driven to move back and forth, so that the clamped position of the frog steel can also be exposed to water, the cooling speed is uniform, and the problem of bending and deformation of the frog steel during solid solution cooling is avoided.

[0006] The utility model is realized through the following scheme: a rail-based frog steel reciprocating moving device, comprising: a plurality of moving mechanisms arranged along the extension direction of the rail, the moving mechanisms being movably mounted on the rail; a driving mechanism for driving the plurality of moving mechanisms to move back and forth along the rail; a plurality of supporting rollers for supporting the frog steel to be moved, the plurality of supporting rollers being connected to the plurality of moving mechanisms, the supporting rollers moving with the movement of the moving mechanisms, and rotating under the action of the frictional force in contact with the frog steel, thereby driving the frog steel to move in the opposite direction.

[0007] The further improvement of the rail-based frog steel reciprocating moving device of the present invention is that: the rail includes two parallel and spaced monorails, and a full-length slide groove is formed on the opposite side of the two monorails; the moving mechanism includes at least two moving shafts for the support rollers to be clamped, and the moving shaft spans between the two monorails and is inserted into the slide grooves on both sides at both ends.

[0008] A further improvement of the rail-based frog steel reciprocating moving device of the present invention is that the support roller is fixed to the moving mechanism through a clamp fixed at the bottom, and the bottom of the clamp is formed with at least two clamping grooves for the corresponding clamping of each moving shaft in the moving mechanism.

[0009] A further improvement of the rail-based frog steel reciprocating moving device of the present invention is that the two ends of the moving shaft are rotatably connected to running wheels through bearings, and the running wheels are embedded in the corresponding chute and can roll along the chute.

[0010] A further improvement of the rail-based frog steel reciprocating moving device of the present invention is that the driving mechanism includes:

[0011] A plurality of passive sprockets are arranged on the outside of a monorail and face all the travel wheels on the monorail one by one, and all the passive sprockets form a sprocket set. A strip hole extending along the length direction of the monorail is opened at a position corresponding to each of the movable axes on the monorail, and the passive sprockets are movably inserted into the strip holes at the corresponding positions and are coaxially fixed with the facing travel wheels.

[0012] A chain connected to the sprocket set and driving all the driven sprockets of the sprocket set to rotate together by its own movement;

[0013] A driving sprocket linked to the chain and driving the chain to move by rotating itself; and

[0014] A driving motor is used to drive the driving sprocket to rotate forward and reverse.

[0015] A further improvement of the rail-based frog steel reciprocating moving device of the present invention is that: the two monorails are supported and fixed by a U-shaped bracket, the drive motor is fixed on the U-shaped bracket, and a transmission shaft is coaxially fixed to the motor shaft of the drive motor. The transmission shaft is installed across the U-shaped bracket and is located below the moving shaft, and the driving sprocket is sleeved and fixed on the transmission shaft and is aligned with the sprocket group.

[0016] A further improvement of the rail-based frog steel reciprocating moving device of the present invention is that: the number of the driving sprockets and the driving motors in the driving mechanism are both two, the two driving motors are respectively fixed at the two ends of the U-shaped bracket, and the two driving sprockets are respectively sleeved and fixed on the two transmission shafts and aligned with the sprocket group.

[0017] A further improvement of the rail-based frog steel reciprocating moving device of the utility model is that the length of the strip-shaped hole is adapted to the reciprocating distance of the moving shaft.

[0018] This new system, when used in conjunction with conventional water-spraying solid solution strengthening equipment, can drive the frog steel to reciprocate during solid solution strengthening, allowing the frog steel to be exposed to water at the clamped position, resulting in a uniform cooling rate and avoiding the problem of bending and deformation of the frog steel during solid solution cooling. Furthermore, by using high-pressure water spraying for solid solution strengthening, the formation of bubbles on the frog steel surface is avoided, achieving a good cooling effect.

[0025] To address the problem of uneven cooling of the frog steel during solution strengthening, which occurs due to the inability of the clamped position of the frog steel to contact water, and thus causes the frog steel to bend and deform during solution cooling, the present invention provides a track-based reciprocating device for frog steel that can be used in conjunction with the conventional water-jet solution strengthening equipment. This device can drive the frog steel to reciprocate during solution strengthening, allowing the clamped position of the frog steel to contact water, resulting in a uniform cooling rate and avoiding the problem of bending and deformation of the frog steel during solution cooling. The following describes the track-based reciprocating device for frog steel using a specific embodiment and accompanying drawings.

[0026] See Figures 1 to 5 As shown, a track-based reciprocating device for frog steel includes: a plurality of moving mechanisms 2 arranged along the extension direction of the track, the moving mechanisms 2 being movably mounted on the track; a driving mechanism for driving the plurality of moving mechanisms 2 to reciprocate along the track; and a plurality of support rollers 3 for supporting the frog steel to be moved. The plurality of support rollers 3 are connected to the plurality of moving mechanisms 2. The support rollers 3 include two vertical poles 31 for connecting to the corresponding moving mechanisms 2, a horizontal shaft 32 fixed between the tops of the two vertical poles 31, and a roller 33 rotatably mounted outside the horizontal shaft 32. The horizontal shaft 32 is supported above the moving mechanism 2 by the vertical poles 31 and is arranged perpendicular to the extension direction of the track. The roller 33 is rotatably supported on the bottom surface of the frog steel. It should be noted that the frog steel reciprocating device can be used for the reciprocating movement of a single frog steel or multiple frog steels, depending on the length of the frog steel and the layout range of the support rollers 3.

[0027] The frog steel reciprocating moving device drives each moving mechanism 2 to move back and forth synchronously along the track through a driving mechanism. The supporting roller 3 is simultaneously driven by the moving mechanism 2 and the gravity of the frog steel placed thereon, so that the roller 33 is forced to roll forward along the lower surface of the frog steel. Under the action of the contact friction between the roller 33 and the frog steel, the frog steel remains stationary or moves in the opposite direction relative to the supporting roller 3. However, in either case, the contact area between the frog steel and the supporting roller 3 changes dynamically, avoiding the problem that the contact area between the frog steel and the roller 33 cannot be exposed, so that the clamped position of the frog steel can also be in contact with water. Each area of the frog steel can be fully exposed to pressurized water for rapid cooling, and the cooling rate is uniform, thereby avoiding bending deformation during the cooling process.

[0028] Regarding the coordination between the frog steel reciprocating moving device and the traditional water jet solid solution strengthening device: a number of support rollers 3 and a number of annular clamping mechanisms in the traditional water jet solid solution strengthening device can be alternately connected to a number of moving mechanisms 2, so that the annular clamping mechanisms and the support rollers 3 move synchronously with the moving mechanisms 2.

[0029] As a preferred embodiment: the track includes two parallel and spaced monorails 1, and a through-length slide 11 is formed on opposite sides of the two monorails 1; the moving mechanism 2 includes at least two moving shafts 21, and the moving shaft 21 spans between the two monorails 1 and is inserted into the slide 11 on both sides at both ends. The bottom of the two uprights 31 of the support roller 3 is fixed with a clamp 34, and the bottom of the clamp 34 is formed with at least two clamping grooves 341 for clamping and fixing each of the moving shafts 21 in the moving mechanism 2. By clamping the clamp 34 on at least two moving shafts 21 at the same time, the reliability of the clamping connection is guaranteed, and the stability of the support roller 3 when it moves with the moving mechanism 2 is guaranteed. Preferably, as Figure 4 and Figure 5 As shown, the two ends of the movable shaft 21 are rotatably connected to the running wheels 7 through the bearings 4, and the running wheels 7 are embedded in the corresponding chute 11 and can roll along the chute 11. The arrangement of the running wheels 7 ensures the stability of the movable shaft 21 moving along the chute 11. The driving mechanism includes: a plurality of passive sprockets 51 arranged on the outside of a monorail 1 and facing all the traveling wheels 7 on the monorail 1 one by one, all the passive sprockets 51 forming a sprocket group, a strip hole 12 extending along the length direction of the monorail 1 is opened at a position corresponding to each of the movable shafts 21 on the monorail 1, the passive sprocket 51 movably passes through the strip hole 12 at the corresponding position and is coaxially fixed with the facing traveling wheel 7; a chain (not shown in the figure) linked to the sprocket group and driving all the passive sprockets 51 of the sprocket group to rotate together by its own movement; a driving sprocket 52 linked to the chain and driving the chain to move by its own rotation; and a driving motor 53 for driving the driving sprocket 52 to rotate forward and reverse. Among them, the two monorails are supported and fixed by a U-shaped bracket 6, the drive motor 53 is fixed on the U-shaped bracket 6, and the motor shaft of the drive motor 53 is coaxially fixed with a transmission shaft 54. The transmission shaft 54 is installed across the U-shaped bracket 6 and is located below the movable shaft 21. The driving sprocket 52 is sleeved and fixed on the transmission shaft 54 and is aligned with the sprocket group. The chain is wound around the driving sprocket 52 and all the passive sprockets 51 of the sprocket group.

[0030] When the driving motor 53 drives the motor shaft to rotate, the driving sprocket 52 is driven to rotate through the transmission shaft 54. Since the driving sprocket 52 is linked to the chain, the rotation of the driving sprocket 52 drives the chain to move, and all the driven sprockets 51 linked to the chain will rotate synchronously, thereby driving all the connected traveling wheels 7 to rotate. The traveling wheels 7 move along the slide groove 11 while rotating. Under the action of the bearing 4, the moving shaft 21 moves with the movement of the traveling wheels 7, but does not rotate due to the rotation of the traveling wheels 7, thereby allowing the support roller 3 to move smoothly.

[0031] It should be noted that the length of the strip hole 12 is adapted to the reciprocating distance of the movable shaft 21. In addition to allowing the passive sprocket 51 to pass through and connect to the travel wheel 7, the strip hole 12 can also limit the reciprocating distance of the movable shaft 21 by setting its length. The specific value is determined by actual application needs, and accordingly, the drive parameters of the drive motor 51 should be adapted to the reciprocating distance.

[0032] As a preferred embodiment: Figures 1 to 3 As shown, the drive mechanism includes two driving sprockets 52 and two driving motors 53. The two driving motors are respectively fixed to the two ends of the U-shaped bracket 6. The two driving sprockets 52 are respectively sleeved and fixed on the two transmission shafts 54 and aligned with the sprocket assembly. The drive mechanism can also be provided with two sprocket assemblies, with the sprocket assemblies of the two drive mechanisms being respectively arranged on the opposite outer sides of the two monorails 1. The structure and principle are the same as above and will not be described in detail here.

[0033] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
