DETAILED DESCRIPTION

[0022] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0023] Example 1

[0024] See also Figures 1-2 A self-priming steel cylinder transporter comprises a mobile vehicle 1, wherein the mobile vehicle 1 is provided with an electromagnet 2, a lifting mechanism 3 and a guard arm 4, wherein the two guard arms 4 can open and close to each other to hold the steel cylinder, and the lifting mechanism 3 drives the electromagnet 2 to rise and fall, and the side of the mobile vehicle 1 has a steel cylinder accommodating space which passes through from top to bottom, and the electromagnet 2 is arranged on the side of the mobile vehicle 1 for adsorbing the steel cylinder.

[0025] The mobile vehicle 1 can move on the ground, and has a steel cylinder accommodating space that is connected up and down on the side of the mobile vehicle 1, and the steel cylinder can be placed in the steel cylinder accommodating space. Since the steel cylinder accommodating space is connected up and down, there is no need to set a bracket, and the steel cylinder standing on the ground can be directly placed against the electromagnet 2 on the side of the mobile vehicle 1. When the electromagnet 2 on the side of the mobile vehicle 1 is energized, the strong magnetic field generated by the electromagnet 2 adsorbs the steel cylinder, and the steel cylinder is closed and held by the guard arm 4 on the mobile vehicle 1. After the electromagnet 2 adsorbs the steel cylinder, the electromagnet 2 is driven to rise and fall by the lifting mechanism 3 to realize the lifting and lowering movement of the steel cylinder. The guard arm 4 can be connected to the mobile vehicle 1 by sliding connection or rotating connection, and the guard arm 4 holds the steel cylinder by sliding or rotating. After holding, the friction between the guard arm and the mobile vehicle 1 or by connecting with the driving mechanism 12 prevents passive opening. When the electromagnet 2 is suddenly powered off, the guard arm 4 holds the steel cylinder, which can prevent the steel cylinder from falling and tipping over. The coordination between the electromagnet 2 and the guard arm 4 ensures that the cylinder can be lifted and lowered, and prevents the cylinder from falling down in the event of an unexpected power outage. After the transport is completed, the power supply of the electromagnet 2 is disconnected, the magnetic properties of the electromagnet 2 disappear, and the cylinder can be removed from the mobile vehicle 1.

[0026] Specifically, the lifting mechanism 3 includes a motor 5, a screw rod 6 and a nut seat 7. The screw rod 6 is rotationally connected to the mobile vehicle 1, the nut seat 7 is slidingly connected to the mobile vehicle 1, and the nut seat 7 is threadedly connected to the screw rod 6. The electromagnet 2 is installed on the nut seat 7, and the motor 5 drives the screw rod 6 to rotate. The nut seat 7 is slidingly connected to the mobile vehicle 1, so that the nut seat 7 can slide up and down along the mobile vehicle 1 but cannot rotate. At the same time, the nut seat 7 is threadedly connected to the screw rod 6. When the motor 5 drives the screw rod 6 to rotate forward and reverse, it can drive the nut seat 7 to move up and down, thereby realizing the up and down lifting movement of the electromagnet 2. The cylinder is adsorbed on the electromagnet 2, and the electromagnet 2 drives the cylinder to move up and down when it moves up and down.

[0027] Specifically, the electromagnet 2 includes an iron core 8, a coil 9 and a magnetic conductive plate 10, wherein the magnetic conductive plate 10 is connected to the iron core 8, the coil 9 is wound on the iron core 8, and the side of the magnetic conductive plate 10 facing the steel cylinder storage space is an arc-shaped surface 11. When the coil 9 is energized, a strong magnetic field is generated in the iron core 8, and the iron core 8 is connected to the magnetic conductive plate 10. After the iron core 8 magnetizes the magnetic conductive plate 10, the magnetic conductive plate 10 can generate a strong magnetic field to adsorb the steel cylinder, so that the steel cylinder is firmly adsorbed. The side of the magnetic conductive plate 10 facing the steel cylinder storage space is an arc-shaped surface 11, that is, the side of the magnetic conductive plate 10 facing the steel cylinder is provided with an arc-shaped surface 11, and the arc-shaped surface 11 and the arc-shaped surface of the side wall of the steel cylinder are mutually fitted, thereby increasing the contact area between the magnetic conductive plate 10 and the steel cylinder, and increasing the adsorption force between the magnetic conductive plate 10 and the steel cylinder.

[0028] Specifically, the arc surface 11 of the magnetic conductive plate 10 is provided with an anti-skid structure. After the magnetic conductive plate 10 adsorbs the steel cylinder, the steel cylinder is lifted up, and the anti-skid structure prevents the steel cylinder from slipping and falling.

[0029] Optionally, the electromagnet 2 and the motor 5 are connected to the controller 35 by signal, and the controller 35 is connected to the operation panel 34 by signal, and the operation panel 34 is arranged on the mobile vehicle 1. The electromagnet 2 is controlled to adsorb and release the steel cylinder, and the motor 5 is controlled to reverse and lift the steel cylinder. During operation, the operation panel 34 sends an electrical signal to the controller 35, and the controller 35 controls the motor 5 and the electromagnet 2 to work after receiving the electrical signal.

[0030] Preferably, the two guard arms 4 are hinged to each other, and the mobile vehicle 1 is provided with a driving mechanism 12 for driving the guard arms 4 to open or close to each other. Specifically, the driving mechanism 12 is an electric telescopic rod 13, and the two guard arms 4 are hinged to each other on the mobile vehicle 1 in an interlaced manner, and the two ends of the electric telescopic rod 13 are respectively hinged to the two guard arms 4. When the electric telescopic rod 13 contracts, it pulls the guard arms 4 closer to each other, so that the guard arms 4 clamp the cylinder. When the electric telescopic rod 13 extends, it pushes the guard arms 4 to open to each other, so that the guard arms 4 release the cylinder.

When the motor 5 rotates forward, the screw 6 drives the nut seat 7 to rise, and the lifting plate 14 is fixed on the nut seat 7, so it can be lifted and lowered synchronously with the nut seat 7. Two guide wheels 15 are arranged on the lifting plate 14, and a connecting rod 19 is arranged in the middle of the guide wheels 15, and one end of the connecting rod 19 is hinged to the slider 16, and the other end is hinged to the middle of the guard arm 4. Under the action of the spring 20, the guard arm 4 opens, and at the same time drives the connecting rod 19 to open and abut against the inner side of the guide wheel 15. When the screw rod 6 rotates forward, it drives the first gear 18 to rotate, and drives the slider 16 to move away from the steel cylinder through the first gear 18. The two connecting rods 19 are arranged between the two guide wheels 15 in a V-shaped state. When the connecting rod 19 moves away from the steel cylinder, the guide wheel 15 pushes the connecting rod 19 inward to close the connecting rod 19, so that the guard arms 4 are closed and hold the steel cylinder. Since the guard arms 4 move into the mobile vehicle 1 at the same time during the closing process, the guard arms 4 clamp the steel cylinder and pull the steel cylinder in the direction of the mobile vehicle 1, so that the steel cylinder and the electromagnet 2 fit more closely to prevent the steel cylinder from slipping.

[0033] Specifically, the lifting plate 14 is connected to the nut seat 7 through a bracket 21, and a cover plate 22 is provided on the lifting plate 14, and the bottom of the cover plate 22 contacts the guard arm 4.

The roller 23 and the lifting plate 14 are lifted and lowered synchronously, and the roller 23 and the cylinder are in contact with each other.

The third sprocket 27 and the roller 23 are fixed together, and the third sprocket 27 and the roller 23 rotate synchronously. When the steel cylinder slides, the third sprocket 27 rotates and drives the first sprocket 24 to rotate through the first transmission chain 28, and the first sprocket 24 drives the second sprocket 25 to rotate through the second transmission chain 29.
