Description

Technical Field

[0001] The present invention relates to the technical field of boiler platforms, and particularly relates to a hoisting device for aluminum structural profiles of a boiler platform with a screen-piercing technology transformation. Background Art

[0002] "Screen superheater" is abbreviated as "SH". The screen superheater is a kind of boiler heating surface, usually arranged in the upper part of the boiler furnace, mainly absorbing the radiant heat in the furnace, and also absorbing a part of the convective heat, used to heat the saturated steam into superheated steam with a certain degree of superheat. During boiler maintenance, in order to reach different positions inside the boiler for maintenance operations, a maintenance lifting platform is often used.

[0003] The traditional maintenance platform cannot pierce the screen. After reaching the position, additional scaffolding needs to be built for the staff to carry out maintenance. In order to make it more convenient for the staff to carry out maintenance, a platform for a boiler with a screen-piercing technology transformation is required. When transforming the boiler platform, aluminum structural profiles are needed, and a hoisting device is required for hoisting the aluminum structural profiles.

[0015] An aluminum structural profile lifting device for the boiler platform with a screen-piercing technology transformation provided by the present invention has the following advantages: By providing a lubrication structure, when hoisting the aluminum structural profile, the placement rack can be guided through the cooperation of the screw rod and the screw sleeve, making the placement rack more stable when moving; Furthermore, when the screw rod rotates, through the cooperation with the pulley and the rotating wheel, the stirring rod can be driven to rotate, which can stir the lubricating oil inside the oil storage tank to prevent the lubricating oil from solidifying, and can also drive the rotating disk to rotate to discharge the lubricating oil regularly and quantitatively. There is no need for an additional power source, saving costs; Furthermore, through the cooperation of the oil guide plate and the telescopic spring, the flowing lubricating oil can be collected, so that the lubricating oil will flow out of the oil outlet to lubricate the steel wire rope only when it reaches a certain weight, preventing the lubricating oil from flowing out all the time and causing waste, thus completing the lubrication work; Furthermore, when the screw rod rotates, it drives the rotor to rotate inside the generator, so that the conductor in the stator winding makes a cutting magnetic induction line movement under the action of the rotating magnetic field to generate current. Utilizing the mechanical energy that would originally be wasted during the process of the placement rack descending, through the screw rod transmission, it is converted into the rotational mechanical energy of the generator, and then the coil of the generator makes a cutting magnetic induction line movement in the magnetic field to generate an induced current, realizing power generation, achieving the purpose of energy recovery and utilization, improving the energy utilization rate, and reducing energy waste; Furthermore, there is no need to additionally set up a complex power transmission mechanism or drive device to drive the generator to rotate. Utilizing the existing descending action of the placement rack, the power generation function is realized without adding too many complex components, making the structure of the entire lifting device simpler and more compact, reducing the equipment cost and space occupation; By setting a clamping structure and using the cooperation of a bidirectional screw and a screw sleeve, two clamping blocks can be driven to clamp the aluminum structural profile, so that the aluminum structural profile is not prone to movement during hoisting. Moreover, by moving the adjusting plate inside the adjusting groove, the height of the adjusting block can be adjusted, enabling it to clamp aluminum structural profiles of different heights. Furthermore, after the two clamping blocks return to their original positions after clamping the aluminum structural profile, the ejecting block will be lifted by the extrusion block, thereby lifting the aluminum structural profile at its top. After lifting the aluminum profile, a gap can be generated between the aluminum profile and the placement rack, facilitating the operator to insert tools for operation, thus improving convenience.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 16 , an aluminum structural profile hoisting device for the boiler platform of the through-screen technology transformation provided by the present invention, includes a base 1 and a moving component 3. The moving component 3 is installed inside the base 1. The top of the moving component 3 is installed with a support frame 2. One side of the bottom of the top of the support frame 2 is installed with an electric hoist 5. The bottom of the electric hoist 5 is installed with a placing rack 4. One side of the top of the support frame 2 is installed with a counterweight block 8.

[0020] The interior of the placement rack 4 is provided with a clamping structure 7. The clamping structure 7 includes a bidirectional screw 709. The bidirectional screw 709 is installed at the middle position inside the placement rack 4. On the outer sides of both ends of the bidirectional screw 709, there are screw sleeves 706. At the top of the screw sleeve 706, there is a clamping block 707. Inside the clamping block 707, there is an adjustment groove 7011. Inside the adjustment groove 7011, there is an adjustment plate 7010. At the top of the adjustment plate 7010, there is an adjustment block 708. Inside one side of the clamping block 707, there is a rotating rod 7012. On one side of the placement rack 4, there is an installation box 701. Inside the installation box 701, there is an installation cavity 702. Inside the installation cavity 702, there is a worm gear 703. One end of the worm gear 703 is fixed to one end of the bidirectional screw 709. On one side of the worm gear 703, there is a worm 704. At the top of the worm 704, there is a handle 705. On both sides inside the placement rack 4, there are guide grooves 7016. Inside the guide grooves 7016, there are ejector blocks 7013. At the bottom of the ejector block 7013, there is an extrusion groove 7015. Inside the extrusion groove 7015, there is an extrusion block 7014. One end of the extrusion block 7014 is fixed to one side of the screw sleeve 706. There are two groups of ejector blocks 7013, and the two groups of ejector blocks 7013 are symmetrically distributed inside the placement rack 4. One end of the rotating rod 7012 penetrates through one side inside the clamping block 707, and the rotating rod 7012 and the clamping block 707 form a threaded connection; Refer to Figures 12 - 16As shown: When hoisting aluminum structural profiles during the renovation of the boiler platform, first install the base 1 at the position where hoisting is required. After installation, first place the aluminum structural profile on the top of the placement rack 4. At this time, since the two sets of screw sleeves 706 are in the initial state, they will drive the extrusion block 7014 to lift the ejector block 7013. Then place the aluminum structural profile on the top of the lifted ejector block 7013. After placement, rotate the handle 705. As the handle 705 drives the worm 704 to rotate, it will drive the worm gear 703 to rotate. When the worm gear 703 rotates, it will drive the bidirectional screw 709 to rotate. When the bidirectional screw 709 rotates, it will drive the two sets of screw sleeves 706 to move towards the middle position, thereby indirectly driving the two sets of clamping blocks 707 to move towards the middle position to clamp the aluminum structural profile, so that the aluminum structural profile is not likely to move randomly during hoisting. When the two sets of screw sleeves 706 move towards the middle position, they will drive the two sets of extrusion blocks 7014 to move into the extrusion groove 7015 in the middle of the ejector block 7013, realizing that when clamping the aluminum structural profile, the ejector block 7013 is received into the interior of the placement rack 4, thus completing the clamping work. When the clamped aluminum structural profile is hoisted to the appropriate position, the operator reverses the handle 705. At this time, the bidirectional screw 709 will also reverse, causing the two sets of screw sleeves 706 to return to the initial position, thereby driving the extrusion block 7014 to also move to the initial position to lift the ejector block 7013, thus lifting the aluminum structural profile on the top of the placement rack 4. After lifting the aluminum profile, a gap can be generated between the aluminum profile and the placement rack 4, facilitating the operator to insert tools for operation. And if the operation is directly carried out on the placement rack 4, the surface of the aluminum profile may be scratched due to the friction and extrusion between the aluminum profile and the tabletop. After lifting the aluminum profile, the possibility of such direct contact and friction is reduced, which helps to protect the smoothness and integrity of the surface of the aluminum profile. And when clamping the aluminum structural profile, the position of the adjusting block 708 can be adjusted by moving the adjusting plate 7010 in the adjusting groove 7011, so that it can clamp aluminum structural profiles of different heights. After the height of the adjusting block 708 is adjusted, through the threaded fit between the rotating rod 7012 and the clamping block 707, one end of it can be abutted against one side of the adjusting plate 7010 to fix the adjusting block 708, and finally complete the height adjustment work of the adjusting block 708.

[0021] On the other side of the top end of the support frame 2, a lubrication structure 6 is provided. The lubrication structure 6 includes an oil storage tank 601, which is installed on one side of the top end of the support frame 2. Inside the oil storage tank 601, a stirring rod 6011 is installed. At the bottom end of the stirring rod 6011, a rotating disk 6012 is installed. An oil outlet groove 6010 is formed inside one side of the top end of the support frame 2. On one side of the bottom of the top end of the support frame 2, an oil storage tank 6013 is installed. Inside the oil storage tank 6013, an oil guide plate 6014 is installed. At the bottom end of the oil guide plate 6014, a telescopic spring 6016 is installed. Through holes 6018 are formed inside both sides of the oil guide plate 6014. Inside the through holes 6018, a guide post 6026 is inserted. At the top end of the guide post 6026, a sealing gasket 6015 is fixed. An oil outlet 6017 is formed at the bottom end of the oil storage tank 6013. Both ends of the telescopic spring 6016 are respectively connected to the bottom end inside the oil storage tank 6013 and the bottom end of the oil guide plate 6014. A telescopic structure is formed between the oil storage tank 6013 and the oil guide plate 6014. There are two groups of through holes 6018, and the two groups of through holes 6018 are symmetrically distributed inside the oil guide plate 6014. A lead screw 605 is movably installed at the middle position of the support frame 2. An outer thread is provided on the outer side of the lead screw 605. An inner thread is provided on the inner side of a nut 606. A threaded connection is formed between the lead screw 605 and the nut 606. On one side of the bottom end of the lead screw 605, a bevel gear set 607 is installed. On one side of the bevel gear set 607, a generator 609 is installed. On one side of the generator 609, a storage battery 608 is installed. Inside the generator 609, a rotor 6025 is installed. Inside one end of the rotor 6025, ratchet teeth 6019 are installed. At the middle position inside one end of the rotor 6025, a connection disk 6024 is installed. One end of the connection disk 6024 is fixed to one side of the bevel gear set 607. An installation groove 6023 is formed inside one side of the connection disk 6024. Inside the installation groove 6023, a fixing rod 6021 is fixed. An outer side of the fixing rod 6021, a ratchet pawl 6020 is installed. On one side of the ratchet pawl 6020, a reset spring 6022 is fixed; Refer to Figures 1 - 11As shown in the figure: After the aluminum structural profile is clamped on the placement rack 4, the external power supply starts the electric hoist 5. After the electric hoist 5 is started, it will drive the placement rack 4 to move upward through the steel wire rope to hoist the aluminum structural profile. When the placement rack 4 moves, it will also drive the wire sleeve 606 to move upward. Since the lead screw 605 is movably connected inside the support frame 2, and the wire sleeve 606 is threadedly connected to the lead screw 605, the wire sleeve 606 will drive the lead screw 605 to rotate when it moves upward. When the lead screw 605 rotates, it will drive the pulley 603 to rotate through the connecting shaft 604. When the pulley 603 rotates, it will drive the rotating wheel 602 to rotate through the belt. When the rotating wheel 602 rotates, it will drive the stirring rod 6011 to rotate. When the stirring rod 6011 rotates, it will drive the rotating disk 6012 to rotate. Only when the notch of the rotating rotating disk 6012 rotates to the position of the oil outlet groove 6010, the lubricating oil inside the oil storage tank 601 will flow into the inside of the oil outlet groove 6010. Since the sponge filled inside the oil outlet groove 6010 will reduce the flow rate of the lubrication, the lubricating oil will slowly flow into the inside of the oil storage tank 6013. When the lubricating oil flows into the inside of the oil storage tank 6013, it will accumulate on the surface of the oil guiding plate 6014. As the lubricating oil becomes more and more and the weight becomes heavier, it will squeeze the telescopic spring 6016 to contract downward. When the oil guiding plate 6014 moves downward, the guide post 6026 will push up the gasket 6015, so that the lubricating oil flows to the bottom end of the oil storage tank 6013 through the through hole 6018. When the weight of the lubricating oil at the top end of the oil guiding plate 6014 becomes lighter, the telescopic spring 6016 will restore the oil guiding plate 6014 to its original position. Through the setting of the above structure, it is prevented that a large amount of lubricating oil flows out and is wasted when the electric hoist 5 is working and lubricated. The flowing lubricating oil will fall onto the steel wire rope of the electric hoist 5 through the oil outlet 6017 to lubricate the steel wire rope. The lubricating grease can form a protective film on the surface of the steel wire rope to prevent air, moisture and other corrosive media from contacting the steel wire, so as to play a role in rust prevention and corrosion prevention, and can also play a lubricating effect on the steel wire rope, reduce the friction between the steel wire ropes, improve the service life, and thus complete the lubrication work of the steel wire rope of the electric hoist 5. When the lead screw 605 rotates forward, it will drive the connecting disk 6024 to rotate forward through the bevel gear set 607. When the connecting disk 6024 rotates forward, the pawl 6020 will slide on the surface of the ratchet tooth 6019 to achieve idling. When the placement rack 4 is lowered, the lead screw 605 will rotate in reverse, so that the connecting disk 6024 rotates in reverse and the pawl 6020 will lock and rotate the ratchet tooth 6019 to drive the rotor 6025 to rotate, so that the magnetic poles of the rotor 6025 generate a rotating magnetic field in the iron core of the stator. The conductors in the stator winding make a cutting magnetic induction line movement under the action of the rotating magnetic field, so as to generate an induced electromotive force in the stator winding. If the stator winding forms a closed loop, there will be an induced current generated, and then electrical energy will be output and stored in the internal of the storage battery 608 for use, realizing the recovery of energy, and finally completing the hoisting work of the aluminum structural profile.
