Description

Technical Field

[0001] The invention relates to the technical field of rust removal equipment, and in particular to a rust removal device for a gas cylinder. Background Art

[0002] A gas cylinder is a type of movable pressure vessel with a bottle-shaped main structure, generally filled with gas (which can be compressed gas, liquefied gas, dissolved adsorbed gas, etc.). Gas cylinders are widely used, and are almost indispensable in both production and daily life. A gas cylinder is a pressure-bearing device with explosion hazards, and the medium it contains is generally flammable, explosive, toxic, and highly corrosive. The use environment is more complex and harsh than other pressure vessels due to its characteristics of mobility, repeated filling, non-fixed operators, and changing use environment. Once a gas cylinder explodes or leaks, fire or poisoning often occurs, and even catastrophic accidents may occur, resulting in serious property losses, casualties, and environmental pollution. To ensure the safe use of gas cylinders, in addition to requiring them to meet the general requirements for pressure vessels, some special regulations and requirements are also needed.

[0003] During the use of gas cylinders, due to the complex use environment, the surface of the gas cylinders is often prone to rust. Therefore, during the use, it is necessary to use a rust remover to grind the gas cylinders and then perform further maintenance. The Chinese utility model patent with application number CN202121794143.6 discloses a new type of industrial gas cylinder rust remover, including a machine body and a grinding pulley group linear motion mechanism, a cylinder is placed at the clamping position on the top of the cylinder rotating mechanism, the top of the cylinder is clamped and connected with a pneumatic cylinder pressing mechanism, the bottom of the lifting mechanism is connected with a cylinder pressing linear motion mechanism, one side of the grinding pulley group linear motion mechanism is connected with a balancing weight block, the bottom of the grinding pulley group linear motion mechanism is connected with an elastic pneumatic double-arm clamping and grinding cylinder rust removal mechanism, and the other end of the machine body is fixedly connected to a negative pressure dust collection mechanism through a connecting pipe; However, during the use of the rust remover, the grinding wheel is directly exposed to the outside. Since the gas cylinder is heavy, it is very easy for the staff with less strength to tilt it when moving the gas cylinder during the process of fixing the gas cylinder. Once the tilted gas cylinder collides with the grinding wheel and damages the grinding wheel, the grinding effect of the grinding wheel is poor, and even derivative problems such as eccentric grinding or over-grinding are caused. In addition, due to various accidents during the use of the gas cylinder, it is very easy for the gas cylinder to deform, and smaller deformation is not easy to be detected. After grinding, the thickness of the outer wall of the gas cylinder may vary greatly, which poses a safety hazard to the use of the gas cylinder.

Figure 1-3 , a gas cylinder rust removal device provided by an embodiment of the present invention, a dust cover 10 is installed on the top side of the rust removal body 1, and two dust suction pipes 11 for dust collection are installed on the dust suction cover 10, and the two dust suction pipes 11 are respectively connected to two grinding motors 4; In addition, a positioning head 12 for clamping the gas cylinder is installed on the inner wall of the top side of the rust removal machine body 1, and a control cabinet 13 for operation is installed on one side of the rust removal machine body 1. It should be noted that in the embodiment of the present invention, the control of the control cabinet 13 can be used to control the lifting frame 2, the traverse frame 3, the grinding motor 4 and many other devices in an integrated manner, and the positioning head 12 can fix the gas cylinder in the rust removal machine body 1.

[0039] In summary, the working principle of a gas cylinder rust removal device provided by an embodiment of the present invention is: When derusting the gas cylinder, the gas cylinder is placed in the derusting machine body 1, and the positioning head 12 is driven by the operating control cabinet 13 to fix the gas cylinder, and then the protection door 9 is closed. At this time, the two protection doors 9 squeeze the two squeezing wheels 609, and the two squeezing wheels 609 drive the two squeezing push racks 606 to move, so that the two squeezing push racks 606 slide horizontally in the two sliding grooves 610, and when the squeezing push racks 606 move, the driving shaft 607 is driven to move, and the driving shaft 607 slides in the driving groove 608, and at the same time, the driving shaft 607 drives the pull rod 605 to rotate, and at this time, the pull rod 605 drives an opening and closing shaft 603 to rotate, and the rotation of the opening and closing shaft 603 drives the opening and closing gear 604 to rotate, so that the opening and closing gear 604 drives The other opening and closing gear 604 is driven to rotate. At this time, the two opening and closing gears 604 drive the two opening and closing covers 601 to rotate and unfold through the two opening and closing rotating shafts 603, and the two transverse moving frames 3 can be driven to move by the operating control cabinet 13, so that the grinding motor 4 drives the grinding brush wheel 5 to grind the gas cylinder; at the same time, the grinding motor 4 is started to lift and lower through the lifting frame 2, and the dust generated by the grinding motor 4 during grinding is absorbed through the dust suction cover 10 and the two dust suction pipes 11, and when the opening and closing rotating shaft 603 rotates, the torsion spring 613 is driven to be stressed. Therefore, when the protective door 9 is opened, the resilience of the torsion spring 613 makes the opening and closing cover 601 automatically closed, so as to avoid the problem that the grinding brush wheel 5 is damaged by impact or causes harm to the staff when loading and unloading the gas cylinder; Furthermore, after the gas cylinder is positioned by the positioning head 12, the rotating locking frame 702 is pushed to put the gas cylinder on the positioning frame 701, and then the locking bolt 703 is tightened. When the lifting frame 2 rises and drives the grinding brush wheel 5 to grind the gas cylinder, the positioning frame 701 is driven to rise synchronously through the multi-directional moving frame 704, so that the circle formed by the positioning frame 701 and the rotating locking frame 702 moves on the outside of the gas cylinder. If the gas cylinder is deformed, it will drive the circle formed by the positioning frame 701 and the rotating locking frame 702 to move in any direction, thereby driving the multi-directional moving frame 704 to move; when the multi-directional moving frame 704 moves horizontally, the lateral block 70 6 slides horizontally in the transverse sliding groove 705, and drives the two reset springs 707 to be stressed. When the multi-directional moving frame 704 moves longitudinally, it moves on the transverse moving block 706, and drives the pull-back spring 708 to be stressed. Therefore, when the multi-directional moving frame 704 moves transversely or longitudinally, it can drive the trigger seat 711 to move. Since the top side of the trigger seat 711 is an arc-shaped concave setting, when the trigger seat 711 moves in any direction, it can squeeze the emergency stop reset switch 710, so that the emergency stop reset switch 710 is triggered, thereby driving the grinding motor 4 to stop and reset, avoiding continuous grinding to damage the gas cylinder, or even causing gas leakage or explosion. Furthermore, when the protective door 9 is closed and the lifting frame 2 is raised for grinding, the two mounting brackets 602 are disengaged from the two rebound rods 808. At this time, under the rebound force of the two return springs 807, the locking rod 802 is driven to reset and rise. When rising, the locking rod 802 simultaneously drives the block 805 to move, so that the block 805 is inserted into the slot 804. At this time, the protective door 9 is locked by the locking rod 802, avoiding the problem of the protective door 9 being accidentally opened during the processing, further ensuring the safety of the gas cylinder during grinding, and at the same time, through physical locking, the locking of the protective door 9 is made more stable.
