A transport device for sulfur hexafluoride gas cylinders

Abstract

This utility model discloses a transport device for sulfur hexafluoride (SF6) cylinders, including a pallet. Four limiting posts and two limiting rods are fixedly connected to the upper surface of the pallet. Multiple placement slots and moving slots are formed on the upper surface of the pallet. A fixing structure is provided within the moving slot. A pushing frame is fixedly connected to one side of the pallet. This utility model, by incorporating a sliding block, a first threaded rod, a fastening nut, an arc-shaped pushing plate, and a rubber pad, uses an adjusting knob to rotate the first threaded rod. The first threaded rod causes the sliding block to move within the sliding slot, which in turn causes the arc-shaped pushing plate to move. The arc-shaped pushing plate then causes the rubber pad to press against one side of the SF6 cylinder, clamping and fixing the SF6 cylinder to prevent it from shaking or tipping over on bumpy roads. Then, rotating the fastening nut tightly presses it against one side of the moving plate, locking the first threaded rod and preventing loosening of the clamp.

Description

Technical Field

[0001] This utility model relates to the field of sulfur hexafluoride cylinder technology, and in particular to a transport device for sulfur hexafluoride cylinders. Background Technology

[0002] Sulfur hexafluoride cylinders are specialized containers used to store high-pressure sulfur hexafluoride gas. They are widely used in the power, chemical and other fields. Their use must strictly adhere to operating procedures and be equipped with appropriate protective measures to ensure safety.

[0003] However, in existing equipment, sulfur hexafluoride cylinders are usually transported by simple trolleys or handcarts. When traveling on bumpy roads, the cylinders are very prone to shaking or even tipping over, posing a serious safety hazard. Therefore, a transport device for sulfur hexafluoride cylinders is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a transport device for sulfur hexafluoride gas cylinders.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a transport device for sulfur hexafluoride cylinders, comprising a pallet, four limiting posts and two limiting rods fixedly connected to the upper surface of the pallet, multiple placement slots and moving slots opened on the upper surface of the pallet, a fixed structure provided in the moving slot, a push frame fixedly connected to one side of the pallet, and four dampers fixedly connected to the bottom of the pallet, a connecting plate fixedly connected to the bottom of each damper, a buffer spring sleeved on each damper, one end of each buffer spring fixedly connected to the bottom of the pallet, and the other end fixedly connected to the upper surface of the corresponding connecting plate;

[0006] The fixed structure includes a bidirectional threaded rod rotatably connected inside the movable groove. One end of the bidirectional threaded rod extends to the outer side of the support plate and is fixedly connected to an adjusting disc. Rotating the adjusting disc causes the bidirectional threaded rod to rotate.

[0007] As a further description of the above technical solution:

[0008] Each of the opposite threaded sections of the bidirectional threaded rod is threaded with a movable block. Each movable block is slidably connected in a movable groove. A first fixed frame is fixedly connected to the upper surface of each movable block. The bidirectional threaded rod drives the two movable blocks to move closer together, and the movable blocks drive the first fixed frame to move.

[0009] As a further description of the above technical solution:

[0010] A movable plate is slidably connected to both of the limiting rods. A second fixed frame is fixedly connected to the bottom of the movable plate. Two lifting columns are rotatably connected inside the second fixed frame. The other end of each lifting column is rotatably connected to the inside of the corresponding first fixed frame. The first fixed frame drives one end of the lifting column to move, so that the other end of the lifting column pushes the movable plate upward through the second fixed frame, causing the movable plate to slide on the two limiting rods.

[0011] As a further description of the above technical solution:

[0012] The upper surface of the movable plate is provided with multiple fixing grooves. Each fixing groove has a sliding groove on one side. Each sliding groove has a sliding block slidably connected inside. Each sliding block has an arc-shaped push plate fixedly connected to one side. Each arc-shaped push plate has a rubber pad fixedly connected to one side. The sliding block drives the arc-shaped push plate to move, and the arc-shaped push plate drives the rubber pad to press against one side of the sulfur hexafluoride cylinder, thus clamping and fixing the sulfur hexafluoride cylinder.

[0013] As a further description of the above technical solution:

[0014] Each of the movable plates has a first threaded rod rotatably connected to one side away from the other. One end of each first threaded rod extends into the interior of the corresponding sliding block and is threaded. When the first threaded rod rotates, it drives the sliding block to move within the sliding groove.

[0015] As a further description of the above technical solution:

[0016] The other end of each of the first threaded rods extends to the outer side of the movable plate and is fixedly connected to an adjustment knob. A fastening nut is threaded onto the first threaded rod. Rotating the fastening nut causes it to press tightly against one side of the movable plate, thus locking the first threaded rod.

[0017] As a further description of the above technical solution:

[0018] The bottom of the two connecting plates on the same side is fixedly connected to a movable wheel, and the bottom of the other two connecting plates is fixedly connected to a brake caster. The brake caster is used to turn the cylinder, making it convenient for staff to transport the sulfur hexafluoride cylinder to the designated location.

[0019] This utility model has the following beneficial effects:

[0020] 1. Compared with existing technologies, this sulfur hexafluoride cylinder transport device, through the arrangement of a bidirectional threaded rod, adjusting disc, moving block, first fixed frame, lifting column, second fixed frame, moving plate, fixed groove, sliding groove, sliding block, first threaded rod, fastening nut, arc-shaped push plate, and rubber pad, etc., rotates the adjusting disc, which drives the bidirectional threaded rod to rotate, causing the two moving blocks to move closer together. The moving blocks drive the first fixed frame to move, and the first fixed frame drives one end of the lifting column to move, so that the other end of the lifting column pushes the moving plate upward through the second fixed frame, causing the moving plate to move upward between the two... Slide the limiting rod to move the moving plate to the appropriate height of the sulfur hexafluoride cylinder. Then rotate the adjusting knob, which drives the first threaded rod to rotate. The first threaded rod drives the sliding block to move in the sliding groove. The sliding block drives the arc-shaped push plate to move. The arc-shaped push plate causes the rubber pad to press against one side of the sulfur hexafluoride cylinder, clamping and fixing the cylinder to prevent it from shaking or even tipping over when driving on bumpy roads. Then rotate the fastening nut to make it tightly press against one side of the moving plate, locking the first threaded rod and preventing the clamp from loosening.

[0021] 2. Compared with the prior art, the transport device for this sulfur hexafluoride cylinder, by setting up a damper and a buffer spring, absorbs and reduces vibrations during transport of the sulfur hexafluoride cylinder through the cooperation of the damper and the buffer spring, further ensuring transport safety.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 8 This utility model provides a transport device for sulfur hexafluoride cylinders: including a pallet 1, four limiting posts 2 and two limiting rods 3 are fixedly connected to the upper surface of the pallet 1, multiple placement slots 4 and moving slots 5 are opened on the upper surface of the pallet 1, a fixing structure 7 is provided in the moving slot 5, a push frame 6 is fixedly connected to one side of the pallet 1, four dampers 8 are fixedly connected to the bottom of the pallet 1, and a connecting plate 9 is fixedly connected to the bottom of each damper 8. The bottom of two connecting plates 9 located on the same side is fixedly connected to moving wheels 11, and the bottom of the other two connecting plates 9 is fixedly connected to brake casters 12. The brake casters 12 are used for steering, making it convenient for staff to transport sulfur hexafluoride cylinders to the designated location.

[0034] To achieve vibration reduction, each damper 8 is fitted with a buffer spring 10. One end of each buffer spring 10 is fixedly connected to the bottom of the support plate 1, and the other end is fixedly connected to the upper surface of the corresponding connecting plate 9. When transporting sulfur hexafluoride cylinders, the damper 8 and the buffer spring 10 work together to absorb and reduce vibration, further ensuring transportation safety.

[0035] To achieve the purpose of fixation, the fixing structure 7 includes a bidirectional threaded rod 701 rotatably connected inside the moving groove 5. One end of the bidirectional threaded rod 701 extends to the outer side of the support plate 1 and is fixedly connected to an adjusting disc 702. Moving blocks 703 are threadedly connected to the opposite threaded sections of the bidirectional threaded rod 701. Each moving block 703 is slidably connected inside the moving groove 5. A first fixing frame 704 is fixedly connected to the upper surface of each moving block 703. A moving plate 707 is slidably connected to both limiting rods 3. A second fixing frame 706 is fixedly connected to the bottom of the moving plate 707. Two lifting columns 70 are rotatably connected inside the second fixing frame 706. 5. The other end of each supporting column 705 is rotatably connected to the interior of the corresponding first fixed frame 704. Multiple fixing grooves 708 are provided on the upper surface of the moving plate 707. A sliding groove 709 is provided on one side of each fixing groove 708. A sliding block 710 is slidably connected inside each sliding groove 709. An arc-shaped push plate 713 is fixedly connected to one side of each sliding block 710. A rubber pad 714 is fixedly connected to one side of each arc-shaped push plate 713. A first threaded rod 711 is rotatably connected through the opposite side of the moving plate 707. One end of each first threaded rod 711 extends into the interior of the corresponding sliding block 710 and... The first threaded rod 711 is threaded, with its other end extending to the outer side of the movable plate 707 and fixedly connected to an adjustment knob. A fastening nut 712 is threaded onto the first threaded rod 711. Rotating the adjustment disc 702 causes the bidirectional threaded rod 701 to rotate, which in turn causes the two movable blocks 703 to move closer together. The movable blocks 703 then move the first fixed frame 704, which in turn moves one end of the lifting column 705. This causes the other end of the lifting column 705 to push the movable plate 707 upwards via the second fixed frame 706, allowing the movable plate 707 to slide on the two limiting rods 3. 7. Move the cylinder to the appropriate height, then rotate the adjustment knob. The adjustment knob drives the first threaded rod 711 to rotate, and the first threaded rod 711 drives the sliding block 710 to move in the sliding groove 709. The sliding block 710 drives the arc-shaped push plate 713 to move, and the arc-shaped push plate 713 drives the rubber pad 714 to press against one side of the sulfur hexafluoride cylinder, clamping and fixing the sulfur hexafluoride cylinder to prevent it from shaking or even tipping over when driving on bumpy roads. Then rotate the fastening nut 712 to make the fastening nut 712 tightly press against one side of the moving plate 707 to lock the first threaded rod 711 and prevent the clamping from loosening.

[0036] Working principle: The sulfur hexafluoride (SF6) cylinder is placed from the fixing slot 708 into the corresponding placement slot 4, with one side of the SF6 cylinder aligned with one side of the placement slot 4. Then, the adjusting disc 702 is rotated, causing the bidirectional threaded rod 701 to rotate. The bidirectional threaded rod 701 moves the two moving blocks 703 closer together. The moving blocks 703 move the first fixing frame 704, which in turn moves one end of the lifting column 705. This causes the other end of the lifting column 705 to push the moving plate 707 upwards via the second fixing frame 706. The moving plate 707 then slides on the two limiting rods 3, moving to the appropriate height for the SF6 cylinder. Finally, the adjusting knob is rotated to adjust the cylinder height. The button drives the first threaded rod 711 to rotate, which in turn drives the sliding block 710 to move within the sliding groove 709. The sliding block 710 then drives the arc-shaped push plate 713 to move, which in turn drives the rubber pad 714 to press against one side of the sulfur hexafluoride cylinder, clamping and fixing it to prevent it from shaking or even tipping over when driving on bumpy roads. Then, the fastening nut 712 is rotated to make it tightly press against one side of the moving plate 707, locking the first threaded rod 711 to prevent the clamp from loosening. When transporting the sulfur hexafluoride cylinder, the damper 8 and the buffer spring 10 work together to absorb and reduce vibration, further ensuring transportation safety.
