Description

Technical Field

[0001] The utility model relates to the technical field of furnace maintenance, in particular to a coking lifting platform for a garbage incinerator. Background Art

[0002] During the process of garbage incineration, due to the complex composition of garbage and improper combustion conditions, some garbage forms a hard coke layer in the furnace, which will have a negative impact on the normal operation of the incinerator. Therefore, when performing maintenance work inside the incinerator, a lifting platform is required to enable workers to perform coke work on the furnace wall of the incinerator. The existing lifting platform usually connects four sets of steel wire ropes to the four corners of the lifting platform, and then uses four sets of motors to drive the four sets of steel wire ropes to move, thereby driving the lifting and lowering movement of the maintenance platform. Once any of the four sets of motors fails, the four sets of motors will not be able to work synchronously, which will cause the maintenance platform to tip to one side, which is easy to cause a safety accident.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] With the acceleration of urbanization and the continuous increase in population, the amount of domestic waste is increasing. Traditional landfill and open-air incineration can no longer effectively solve the problem of waste disposal. As an efficient and environmentally friendly way of waste disposal, waste incineration can significantly reduce the volume of waste by converting it into heat energy, and the heat energy generated during the incineration process can be further utilized, such as power generation and heating. Therefore, waste incinerators have become important equipment for modern urban waste disposal. During the process of waste incineration, due to the complex composition of the waste and improper combustion conditions, some of the waste forms a hard coke layer in the furnace, which will have a negative impact on the normal operation of the incinerator, so that the staff need to enter the furnace to knock it down.

[0023] Embodiment 1:

[0024] Based on the technical defects of the existing technology that cause safety accidents due to the easy tilt of the lifting platform, please refer to Figure 1-Figure 4The utility model provides a garbage incinerator coking lifting platform, which adopts a single motor 211 to realize the lifting operation of the maintenance platform 3, which can avoid the problem of the maintenance platform 3 tipping over and causing safety accidents due to the asynchronous movement of the wire rope 25, and also reduce the installation cost. The lifting platform includes a top plate 1 installed on the top of the incinerator and a maintenance platform 3 inside the incinerator. A synchronous lifting mechanism 2 is installed on the top plate 1 to prevent the maintenance platform 3 from tilting to one side. The synchronous lifting mechanism 2 is connected to the maintenance platform 3, and the bottom of the maintenance platform 3 near both ends is fixed with an anti-sway mechanism 4 to prevent the maintenance platform 3 from shaking; after the overall installation, the synchronous driving mechanism can drive the maintenance platform 3 to move up and down, so as to facilitate the staff to stand on the maintenance platform 3 and perform coking work on the furnace wall. During the lifting process, the anti-sway mechanism 4 is used to contact the furnace wall, so as to avoid the problem of the maintenance platform 3 shaking during the coking process.

[0025] To ensure that the inspection platform 3 can be raised and lowered without tipping over, please refer to Figure 2 The synchronous lifting mechanism 2 includes a driving assembly 21 installed on the top plate 1, and a synchronous shaft 22 is connected to the driving assembly 21. The synchronous shaft 22 is rotatably connected to the bearing seat 23, and the bearing seat 23 is installed on the top plate 1. Both ends of the synchronous shaft 22 are fixed with rope drums 24, and a steel wire rope 25 is wound around the rope drum 24. The two ends of the steel wire rope 25 are detachably connected to the two ends of the maintenance platform 3 respectively; the driving assembly 21 works and drives the synchronous shaft 22 to rotate, and the synchronous shaft 22 drives the rope drum 24 to rotate. Since the steel wire rope 25 is wound around the rope drum 24, when the rope drum 24 rotates, the two ends of the steel wire rope 25 can be pulled synchronously to move, thereby making the maintenance platform 3 move up and down.

[0026] To facilitate the rotation of the synchronous shaft 22, please refer to Figure 2 The driving assembly 21 includes a motor 211 installed on the top plate 1, and a bevel gear 212 is fixedly provided on the output shaft of the motor 211. The bevel gear 212 is meshed with the bevel gear 213, and the bevel gear 213 is fixedly connected to the synchronous shaft 22. The motor 211 can drive the synchronous shaft 22 to rotate through the meshing action of the bevel gear 212 and the bevel gear 213, and the transmission direction is changed, so that the installation of the motor 211 is convenient.

[0027] In order to ensure the stability of the wire rope 25 during the transmission process, guide pulleys 26 for changing the movement direction of the wire rope 25 are fixed at both ends of the top plate 1; the wire rope 25 can bypass the guide pulley 26, and the guide pulley 26 is used to change the movement direction of the wire rope 25, so that the wire rope 25 drives the maintenance platform 3 to rise and fall more smoothly.

[0028] In order to improve the safety of the coking operation, a guardrail 5 is installed on the surface of the maintenance platform 3 near the outer edge; the guardrail 5 can be used to provide safety protection for the workers.

[0029] Embodiment 2:

[0030] Since the inspection platform 3 is suspended in the furnace by the steel wire rope 25, the inspection platform 3 is easy to shake during the coking process, which causes the staff to stand unsteadily. To solve this problem, based on the first embodiment, please refer to Figure 3 The anti-sway mechanism 4 includes two hydraulic cylinders 41 installed at the bottom of the maintenance platform 3. A "U"-shaped movable frame 42 is fixed on the telescopic end of the two hydraulic cylinders 41. The movable frame 42 is sleeved in two guide sleeves 43. The two guide sleeves 43 are fixed to the bottom of the maintenance platform 3. Both ends of the movable frame 42 are rotatably connected with rollers 44. First, start the pneumatic cylinder 1 to drive the movable frame 42 to move. The movable frame 42 drives the roller 44 to contact the inner wall of the furnace, which can prevent the maintenance platform 3 from shaking from the left and right directions.

[0031] In order to further improve the anti-sway effect of the inspection platform 3, a hydraulic cylinder 2 45 is installed on the movable frame 42. A hinge block 46 is fixed on the telescopic shaft of the hydraulic cylinder 2 45. The hinge block 46 is hinged to the outer walls of the two movable rods 48 through two hinge rods 47. The two movable rods 48 are respectively mounted on the two ends of the fixed rod 410. The fixed rod 410 is fixed to the inner side of the movable frame 42 through a fixed plate 411. One end of the two movable rods 48 is rotatably connected with roller 2. Start the hydraulic cylinder 2 45 and drive the movable rod 48 to move through the hinge block 46 and the hinge rod 47. The movable rod 48 drives the roller 2 to contact the other inner wall of the furnace, which can prevent the inspection platform 3 from shaking from the front and rear directions, thereby making the inspection platform 3 stable.

[0032] Through the above embodiment, it can be known that after the whole is installed, the staff enters the maintenance platform 3, and then under the action of the synchronous drive mechanism, the motor 211 can drive the synchronous shaft 22 to rotate through the meshing action of the bevel gear 1 212 and the bevel gear 2 213, and the synchronous shaft 22 drives the rope drum 24 to rotate. Since the wire rope 25 is wound around the rope drum 24, when the rope drum 24 rotates, the two ends of the wire rope 25 can be pulled synchronously to move, so that the maintenance platform 3 can be lifted and lowered. During the lifting and lowering of the maintenance platform 3, the staff can The inner wall of the furnace is coked, and in the process of lifting and lowering the inspection platform 3, through the setting of the anti-sway mechanism 4, the pneumatic cylinder 1 is started first to drive the movable frame 42 to move, and the movable frame 42 drives the roller 1 44 to contact the inner wall of the furnace, which can prevent the inspection platform 3 from shaking from the left and right directions, and then the hydraulic cylinder 2 45 is started and the movable rod 48 is driven to move through the hinge block 46 and the hinge rod 47, and the movable rod 48 drives the roller 2 to contact the other inner wall of the furnace, which can prevent the inspection platform 3 from shaking from the front and back directions, so that the inspection platform 3 can be stabilized.
