Abstract
Description
Technical Field
[0001] This application belongs to the technical field of metallurgical strip steel production equipment, specifically referring to a magnetic suction loop support vehicle. Background Technology
[0002] Currently, various types of carriages are used in the production process of steel enterprises, such as the support carriage in a looper. The support carriage in a looper has multiple carriages, and the support carriages will engage and disengage during the operation of the looper. The engagement and disengagement devices of each support carriage are generally of the type of hook and fixing pin. For support carriages with wider carriages, there will be engagement and disengagement devices on both sides of the direction of travel.
[0003] Currently, the engagement of the hooks and fixing pins in the engagement and disengagement devices cannot guarantee complete synchronization between the front and rear car bodies. Especially when the hooks and fixing pins are first engaged, the moving front car body pulls the stationary rear car body, causing the rear car body to lurch forward. It then pauses briefly due to frictional resistance, repeating this process until the forward inertial force exceeds the frictional resistance, at which point it will match the speed of the front car body. During this process, the hooks and fixing pins will collide and separate to some extent, causing fluctuations in the power of the front car body. In some cases, the hooks and fixing pins may also disengage, i.e., the hooks lift up and disengage from the fixing pins, causing the front and rear cars to separate. This separation is particularly problematic in loopers with high punching and unloading speeds, as it significantly impacts the production rhythm. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this application provides a magnetically plucked support vehicle that can prevent the vehicle bodies of the front and rear vehicles from separating during movement.

[0006] The magnetic attraction device is located at the same height at both the front and rear ends of the vehicle body, and the magnetic attraction devices at the front and rear ends have opposite magnetic properties.
[0007] The magnetic attraction device includes a magnet, a guide rod, and a spring; the guide rod is a three-section coaxial cylinder, the diameter of the second section of the three-section coaxial cylinder is larger than the diameter of the first and third sections; the spring is sleeved on the cylinder of the third section of the guide rod; the magnet is installed on the cylinder of the first section of the guide rod.
[0008] At equal heights at both the front and rear ends of the vehicle body, three coaxial cylindrical cavities with axes parallel to the vehicle's direction of travel are provided, with the diameter of the second portion of each cylindrical cavity being larger than the diameters of the first and third portions. The second portion of the three coaxial cylindrical cavity is used to accommodate the cylinder of the second portion of the guide rod and the spring.

One end face of the spring is abutted by the end face of the cylinder of the second portion of the guide rod, and the other end face of the spring abuts against the end face of the second portion of the cylindrical cavity. The first portion of the three coaxial cylindrical cavity is used to accommodate the cylinder of the first portion of the guide rod on the side where the magnet is mounted, with the magnet exposed on the outside of the vehicle body.
[0009] Furthermore, in the magnetic sling support vehicle provided in this embodiment, the magnet is a permanent magnet.
[0010] Furthermore, in the magnetic sling support vehicle provided in this embodiment, the magnet is an electromagnet.
[0011] Furthermore, in the magnetic sling support vehicle provided in this embodiment, the magnetic force of the magnet is not less than the frictional resistance of the vehicle body and the additional driving resistance of the vehicle body.
[0012] Furthermore, according to the magnetic sling support vehicle provided in this embodiment, the length of the cylinder of the third part of the guide rod on the side where the spring is installed is greater than the maximum length of the spring, and the remaining length of the cylindrical cavity of the third part of the vehicle body that accommodates this section of the cylinder is greater than the maximum stroke of the spring.
[0013] Furthermore, according to the magnetic sling support vehicle provided in this embodiment, the length of the cylinder of the first part of the guide rod on the side where the magnet is installed is not less than the sum of the maximum stroke of the spring and the length of the first part of the cylindrical cavity on the vehicle body that accommodates this section of cylinder.
[0014] Furthermore, according to the magnetic suction loop support vehicle provided in this embodiment, a fixed stop block is also provided at the bottom of the vehicle body, and a magnet is installed on the stop block. The stop block stops the vehicle body under the action of a stop seat fixed on the ground at the stopping position of the vehicle body; the magnetic suction device is provided on the stop seat, and the magnetism of the magnetic suction device is opposite to the magnetism of the magnet on the stop block.

[0016] Furthermore, according to the magnetic suction loop support vehicle provided in this embodiment, no less than two sets of the magnetic suction devices are provided on both sides of the vehicle body in the direction of travel.
[0017] The beneficial effects of this utility model are as follows: The magnetic sling support vehicle provided in this embodiment, when the front and rear vehicles with the magnetic sling device are close to each other, will be attracted together by the magnetic force due to the opposite polarity of the magnets, without the risk of disengagement. At the same time, the spring in the magnetic sling device will alleviate and absorb the force when the vehicle bodies collide and reduce the vibration, thus reducing the power fluctuation of the front vehicle.

[0026] The embodiments of this application will now be further described in conjunction with the accompanying drawings and specific implementation details.
[0027] Figure 1 This is a structural diagram of the connection type of the attachment and disengagement device for supporting vehicles in the prior art.
[0028] like Figure 1 As shown, in the prior art, the hooking and disengaging device of the supporting vehicle mainly includes hook 1 and fixing pin 2. However, the mutual hooking of hook 1 and fixing pin 2 cannot guarantee the complete synchronization of the front and rear vehicle bodies. Especially when hook 1 and fixing pin 2 are just hooked, the moving front vehicle body pulls the stationary rear vehicle body, and the rear vehicle body will lurch forward. Then it will stop briefly due to frictional resistance. This process repeats until the forward inertial force exceeds the frictional resistance and the speed is equal to that of the front vehicle body. During this process, hook 1 and fixing pin 2 will have some collision and separation, which will cause some fluctuation in the power of the front vehicle body. At the same time, in some cases, hook 1 may disengage from fixing pin 2, that is, hook 1 will lift up and disengage from fixing pin 2, resulting in the separation of the front and rear vehicles.
[0029] Therefore, this application provides a magnetically assisted sliding support vehicle, which can effectively prevent the vehicle bodies of the front and rear vehicles from separating during movement.
[0030] Figure 2 This is a schematic diagram of the structure of the magnetic sling support vehicle provided in the embodiments of this application.
[0031] like Figure 2 As shown, in this embodiment, the magnetic sling support vehicle mainly includes a vehicle body 7 and a magnetic sling device; wherein, the magnetic sling device is located at the same height at both ends of the vehicle body 7, and the magnetic properties of the magnetic sling devices located at the front and rear ends are opposite, so the magnetic sling devices between the two vehicle bodies 7 at the front and rear will attract each other due to their opposite magnetic properties.
[0032] like Figure 2 As shown, the magnetic attraction device includes a magnet 3, a guide rod 4, and a spring 5. The guide rod 4 is a three-section coaxial cylinder, with the diameter of the second section being larger than the diameters of the first and third sections. The spring 5 is fitted onto the cylinder of the third section of the guide rod 4. The magnet 3 is mounted on the cylinder of the first section of the guide rod 4. In this embodiment, the three-section coaxial cylinder can be divided into a first section, a second section, and a third section from left to right, wherein the diameter of the cylinder of the second section is larger than the diameters of the cylinders of the first and third sections. The diameters of the cylinders of the first and third sections can be equal, or the diameters of the cylinders of the first and third sections can be larger, or the diameters of the cylinders of the first and third sections can be smaller. That is, in this embodiment, the three-section coaxial cylinder is a three-section coaxial cylinder that is thicker in the middle and thinner at both ends. The spring 5 and the magnet 3 are both mounted on the cylinders that are thinner at both ends.
[0033] At equal heights at both the front and rear ends of the vehicle body 7, three coaxial cylindrical cavities 6 are provided, with their axes parallel to the direction of travel of the vehicle body 7. The diameter of the second part of the cylindrical cavity 6 is larger than the diameters of the first and third parts. The cylindrical cavity of the second part of the three coaxial cylindrical cavity 6 is used to accommodate the cylinder of the second part of the guide rod 4 and the spring 5. The cylindrical cavity of the third part of the three coaxial cylindrical cavity 6 is used to accommodate the cylinder of the third part of the guide rod 4 on the side where the spring 5 is installed. One end face of the spring 5 is abutted by the end face of the cylinder of the second part of the guide rod 4, and the other end face of the spring 5 abuts against the end face of the second part of the cylindrical cavity 6. The cylindrical cavity of the first part of the three coaxial cylindrical cavity 6 is used to accommodate the cylinder of the first part of the guide rod 4 on the side where the magnet 3 is installed. The magnet 3 is exposed on the outside of the vehicle body 7. In this embodiment, the three-section coaxial cylindrical cavity 6 can be divided into a first section, a second section, and a third section from left to right. The diameter of the cylindrical cavity 6 in the second section is larger than the diameters of the cylindrical cavities in the first and third sections. The diameters of the cylindrical cavities in the first and third sections can be equal, or the diameters of the first and third sections can be larger, or the diameters of the first and third sections can be smaller. That is, in this embodiment, the three-section coaxial cylindrical cavity 6 is a three-section coaxial cylindrical cavity 6 that is thicker in the middle and thinner at both ends. The thicker cylindrical cavity 6 in the middle is used to accommodate the middle column of the guide rod 4 and the spring 5. The thinner cylindrical cavity 6 at one end is used to accommodate the thinner column on the side of the guide rod 4 where the spring 5 is installed. The thinner cylindrical cavity 6 at the other end is used to accommodate the thinner column on the side of the guide rod 4 where the magnet 3 is installed. One end face of the spring 5 is pressed against the end face of the middle column of the guide rod 4, and the other end face is pressed against the end face of the thicker cylindrical cavity 6 in the middle. The magnet 3 installed on the guide rod 4 is exposed on the outside of the vehicle body 7.
[0034] In this embodiment, the magnet 3 installed on the guide rod 4 is a permanent magnet or an electromagnet. Moreover, the magnetic force of the magnet 3 is not less than the frictional resistance of the vehicle body 7 and the additional driving resistance of the vehicle body 7. That is, after the magnets 3 on the front and rear vehicle bodies 7 attract each other, the attracted magnets 3 will not separate due to the frictional force of the vehicle body 7 or the driving resistance.
[0035] like Figure 2As shown, in this embodiment, the length of the cylinder at the third part of the guide rod 4 on the side where the spring 5 is installed is greater than the maximum length of the spring 5, and the remaining length of the cylindrical cavity 6 on the vehicle body 7 that accommodates this cylinder is greater than the maximum stroke of the spring 5. The length of the cylinder at the first part of the guide rod 4 on the side where the magnet 3 is installed is not less than the sum of the maximum stroke of the spring 5 and the length of the cylindrical cavity 6 on the vehicle body 7 that accommodates this cylinder. In this embodiment, the spring 5 in the magnetic attraction device will alleviate and absorb the force when the vehicle bodies 7 collide and reduce the vibration, reducing the power fluctuation of the front vehicle. Therefore, the non-detachment of the attraction force of the magnet 3 and the vibration relief of the spring 5 will enable the front and rear vehicles to achieve speed synchronization as quickly as possible.
[0036] In this embodiment, a fixed stop block 8 is also provided at the bottom of the vehicle body 7. The stop block 8 is located on both sides of the vehicle body 7. A magnet 9 of the stop block is installed on the stop block 8. The stop block 8 stops the vehicle body 7 under the action of a stop seat 10 fixed on the ground at the stopping position of the vehicle body 7. The magnetic attraction device is provided on the stop seat 10, and the magnetism of the magnetic attraction device is opposite to the magnet 9 of the stop block.
[0037] When the rear vehicle body 7 needs to stop, the magnet 3 of the magnetic attraction device on the stop seat 10, which is equipped with the magnetic attraction device, will contact the magnet 9 of the stop block on the rear vehicle body 7. Because the polarities of the two are opposite, they are attracted by magnetic force. The spring 5 of the magnetic attraction device on the stop seat 10 relieves the force of the collision and reduces the vibration. At the same time, because the stop seat 10 is fixed, the blocking force is greater than the attraction force between the magnets of the front and rear vehicles, causing the front and rear vehicles to separate. Due to the reaction force at the moment of separation and other factors, the rear vehicle will have a tendency to move in the opposite direction and slide. However, because the magnet 3 on the stop seat and the magnet 9 on the stop block of the vehicle body 7 are attracted, it will not move or slide.
[0038] In one embodiment, if the vehicle body 7 is relatively narrow, the magnetic attraction device can be located in the middle of the vehicle body 7, and only one set of the magnetic attraction device is needed.
[0039] like Figure 3 As shown, in one embodiment, if the vehicle body 7 is relatively wide, at least two sets of the magnetic attraction devices can be provided on both sides of the vehicle body 7 in the direction of travel. Figure 3 As shown, two sets of magnetic attraction devices are provided at both the front and rear ends of the vehicle body 7, and two stop blocks 8 are provided on both sides of the bottom of the vehicle body 7; the two stop blocks 8 interact with the two stop seats 9 on the ground to stop the vehicle body 7.
[0040] The magnetic sling support vehicle provided in this embodiment, when the front and rear vehicles equipped with the magnetic attraction device approach each other, will be attracted together by the magnetic force due to the opposite polarity of the magnets 3, eliminating the risk of disengagement. At the same time, the spring 5 in the magnetic attraction device will alleviate and absorb the force of the collision of the vehicle bodies 7 and reduce vibration, thus reducing the power fluctuation of the front vehicle. Therefore, the attraction of the magnets 3 and the vibration relief of the spring 5 will enable the front and rear vehicles to achieve speed synchronization as soon as possible, effectively preventing the vehicle bodies 7 of the front and rear vehicles from separating during movement.
