Description

Technical Field

[0001] The invention belongs to the technical field of dry coke quenching, in particular to a position limiting and anti-collision device for a dry coke quenching hoist. Background Art

[0002] The CDQ elevator is one of the key equipment in the CDQ system. It is mainly used to lift the coke drum filled with red coke from the bottom of the lifting shaft to the top of the CDQ furnace, and to lift and lower the coke drum and load coke above the CDQ furnace loading hopper.

[0009] Preferably, a top plate is fixedly connected to the output end of the cylinder, and a spring is fixedly connected to the moving block.

[0010] Preferably, one end of the spring away from the moving block is fixedly connected to the first slide groove, and both ends of the connecting frame are rotatably connected to the top plate and the receiving seat respectively. The moving block, spring and connecting frame are each provided with two and are symmetrically arranged.

[0011] Preferably, a limiting assembly is provided on the fixing plate, and the limiting assembly comprises a support rod fixedly connected to the fixing plate, and the top of the support rod is fixedly connected to the limiting plate.

[0012] Preferably, the fixing plate is symmetrically provided with a second sliding groove, a switch is provided in the second sliding groove, and the bottom of the limiting plate is rotatably connected with an extrusion rod.

[0013] Preferably, the end of the squeezing rod is slidably connected in the second sliding groove, and two of the switches and the squeezing rods are provided and are symmetrically arranged.

[0014] Preferably, a locking assembly is provided on the limit plate, and the locking assembly includes U-shaped plates symmetrically arranged at both ends of the limit plate, a shaking generator is provided in the U-shaped plate, an electric push rod is provided at the bottom of the limit plate, and a push rod is fixedly connected to the output end of the electric push rod.

[0015] Preferably, the shaking generator is rotatably connected to a rotating wheel, and the rotating wheel is provided with a slot.

[0016] Preferably, the cable passes through the U-shaped plate, the cable is arranged in the slot, the push rod is arranged in a semicircular shape, and the shaking generator, the rotating wheel, the slot, the electric push rod and the push rod are all provided with two and are symmetrically arranged.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention arranges two anti-collision components on both sides of the bracket. When the hoist drives the coke tank to rise and the coke tank collides with the derrick due to various factors, the air pump provides air pressure buffering, the top plate drives the two connecting frames to be tightened, and the spring provides buffering force for the top plate through the moving block and the connecting frame. Under the dual vibration reduction of the air pump and the spring, the collision accident of the coke tank during the lifting process of the hoist can be effectively avoided, the risk of equipment damage and personal injury can be reduced, and the positioning accuracy of the coke tank can be improved to ensure the accurate docking of the coke tank during the lifting or lowering process.

[0019] 2. The present invention provides a limit plate. When the hoist lifts the coke drum to the top of the derrick, the limit rod is attached to the top of the derrick. As it continues to rise, the support rod contracts, and the limit plate drives the two extrusion rods to open in the two second slide grooves. When it reaches a certain level, the end of the extrusion rod triggers a switch, and the sensor arranged in the fixed plate transmits a signal to the cab. The operator can obtain the position information in time for subsequent operations, thereby avoiding possible safety accidents.

[0020] 3. The present invention arranges a shaking generator. When the whole device suddenly falls during the lifting process, the rotation speed of the impeller increases due to the excessively fast descent speed, so that the shaking generator generates electricity and provides power for the two electric push rods. The two push rods are pushed out to squeeze the cables, and under the action of the U-shaped plate and the push rods, they are locked to prevent the whole device from continuing to fall, thereby ensuring the safe operation of the hoist, avoiding production interruptions caused by equipment failures, ensuring the continuity and stability of production, and effectively preventing the coke drum from falling from high altitudes, thereby significantly improving construction safety.

[0021] The above summary is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. It should be pointed out that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size, and any size is only exemplary and not restrictive.

[0036] Embodiment 1:

[0037] See also Figure 1 - Figure 6 As shown, a position limiting and anti-collision device for a dry coke quenching elevator comprises a base 1, the base 1 comprises a bracket 11, a bottom plate 12 is symmetrically arranged at the bottom of the bracket 11, an air pump 13 is rotatably connected to the bottom plate 12, and a top ear 14 is symmetrically arranged on the top of the bracket 11; a coke tank 2, the coke tank 2 is arranged on the base 1, the base 1 is used to receive the coke tank 2, and is used to enable a hoisting assembly 3 to hoist the coke tank 2 through it, the bracket 11 is the main supporting structure of the base 1, the bracket 11 is tightly fitted to the coke tank 2 to prevent the coke tank 2 from shaking during the lifting process, the bottom plate 12 is used to seal the bottom of the coke tank 2, the air pump 13 is used to provide a driving force for the bottom plate 12, so that the bottom plate 12 can rotate at the bottom of the bracket 11, when the two bottom plates 12 are opened, the red coke stored in the coke tank 2 falls into the dry quenching furnace, and the hoisting assembly 3 hoists the coke tank 2 through the top ear 14;

[0038] The hoisting assembly 3 includes a fixing plate 31, a hook 36 is symmetrically arranged at the bottom of the fixing plate 31, the hook 36 is arranged on the top ear 14, the fixing plate 31 is used to receive the hook 36 and the top ear 14, a sensor is arranged in the fixing plate 31, the hook 36 hooks the top ear 14, and the base 1 and the coke tank 2 are hoisted;

[0039] The anti-collision component 4 includes a receiving seat 41 fixedly connected to the side of the bracket 11, a cylinder 42 is arranged on the receiving seat 41, a cross seat 44 is sleeved on the cylinder 42, a first slide groove 45 is symmetrically opened at the end of the cross seat 44, a moving block 46 is slidably connected in the first slide groove 45, a connecting frame 48 is rotatably connected to the moving block 46, and two anti-collision components 4 are provided and are symmetrically arranged. The receiving seat 41 is used to fix the anti-collision component 4 on the bracket 11 and to receive the cylinder 42. The cylinder 42 is squeezed to provide a buffering force under the air pressure inside it. The cross seat 44 is used to receive the connecting frame 48. The first slide groove 45 is used to provide a guide for the moving block 46. The moving block 46 is pushed by the connecting frame 48 and moves in the first slide groove 45.

[0040] Specifically, electric hoists 32 are symmetrically arranged on the fixed plate 31, cables 33 are arranged on the electric hoists 32, multiple connecting wires 34 are fixedly connected to the fixed plate 31, and covers 35 are fixedly connected to the ends of the multiple connecting wires 34. The electric hoist 32 is used to vertically lift the entire device. The cables 33 are formed by twisting multiple groups of steel wires, have good tensile resistance, and have excellent wear resistance. The dry quenching coke elevator hoists the entire device through the cables 33, and the multiple connecting wires 34 are used to hoist the covers 35. The covers 35 are used to seal the coke tank 2 to prevent the red coke in the coke tank 2 from spilling out during the lifting process of the coke tank 2.

[0041] Furthermore, a top plate 43 is fixedly connected to the output end of the cylinder 42 , and a spring 47 is fixedly connected to the moving block 46 . The top plate 43 is close to the derrick to squeeze the cylinder 42 , and the spring 47 is used to provide thrust for the moving block 46 .

[0042] Furthermore, one end of the spring 47 away from the moving block 46 is fixedly connected to the first slide groove 45, and the spring 47 opens or contracts as the moving block 46 moves. The two ends of the connecting frame 48 are respectively rotatably connected to the top plate 43 and the receiving seat 41. As the top plate 43 moves, the connecting frame 48 opens and tightens. There are two moving blocks 46, springs 47 and connecting frames 48, and they are symmetrically arranged.

[0043] As can be seen from the above, when the hoist drives the coke tank 2 to rise, and the coke tank 2 collides with the derrick due to various factors, the top plate 43 approaches the derrick and squeezes the cylinder 42, and the air pump 13 provides air pressure buffering. Because the two ends of the two connecting frames 48 are respectively rotated to connect the top plate 43 and the receiving seat 41, the top plate 43 is squeezed, and the top plate 43 drives the two connecting frames 48 to tighten. Because the middle part of the connecting frame 48 is rotated and connected to the moving block 46, the two moving blocks 46 move in the opposite direction in the two first slide grooves 45 as pushed by the connecting frame 48, and the spring 47 is tightened, and the spring 47 provides buffering force for the top plate 43 through the moving block 46 and the connecting frame 48. Under the dual vibration reduction of the air pump 13 and the spring 47, the collision accident of the coke tank 2 can be effectively avoided during the lifting process of the hoist, and the risk of equipment damage and personal injury can be reduced. It can also improve the positioning accuracy of the coke tank 2 to ensure the accurate docking of the coke tank 2 during the lifting or lowering process.

[0044] Embodiment 2:

[0045] See also Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that a limiting assembly 5 is provided on the fixed plate 31, and the limiting assembly 5 includes a support rod 51 fixedly connected to the fixed plate 31, and a limiting plate 52 is fixedly connected to the top of the support rod 51, and the support rod 51 is retractably arranged, and the support rod 51 is used to provide supporting force for the limiting plate 52, and the limiting plate 52 is used to limit the entire device.

[0046] Specifically, a second slide groove 53 is symmetrically opened on the fixed plate 31, a switch 54 is arranged in the second slide groove 53, a squeezing rod 55 is rotatably connected to the bottom of the limit plate 52, the second slide groove 53 is used to receive the switch 54, and the second slide groove 53 is used to provide guidance for the squeezing rod 55, the switch 54 is used to control the sensor arranged in the fixed plate 31 to transmit a signal to the cab, and the squeezing rod 55 is used to squeeze the switch 54 to trigger the switch 54.

[0047] Furthermore, as the limiting plate 52 is pressed downward, the end of the squeezing rod 55 is slidably connected in the second sliding groove 53 , and two switches 54 and two squeezing rods 55 are provided and are symmetrically arranged.

[0048] As can be seen from the above, when the hoist lifts the coke tank 2 to the top of the derrick, the limit rod is attached to the top of the derrick, and as it continues to rise, the limit plate 52 presses down on the support rod 51, and the support rod 51 contracts. Under the squeezing of the limit plate 52, the limit plate 52 drives the two extrusion rods 55 connected to its bottom rotation to open in the two second slide grooves 53. When the ends of the two extrusion rods 55 reach a certain degree in the two second slide grooves 53, the ends of the extrusion rods 55 trigger the switch 54, which controls the sensor set in the fixed plate 31 to send a signal to the cab, so that the operator can timely understand the position information for subsequent operations, thereby avoiding possible safety accidents.

[0049] Embodiment three:

[0050] See also Figure 5 - Figure 6 As shown, this embodiment is basically the same as the previous embodiment, except that a locking assembly 6 is provided on the limit plate 52, and the locking assembly 6 includes a U-shaped plate 61 symmetrically arranged at both ends of the limit plate 52, a shaking generator 62 is provided in the U-shaped plate 61, an electric push rod 63 is provided at the bottom of the limit plate 52, and a push rod 64 is fixedly connected to the output end of the electric push rod 63, the U-shaped plate 61 is used to accommodate the shaking generator 62, and the U-shaped plate 61 is used to limit the cable 33, the shaking generator 62 is used to provide power to the electric push rod 63, the electric push rod 63 is used to provide driving force for the push rod 64, and the push rod 64 is used to squeeze the cable 33, which cooperates with the U-shaped plate 61 to lock the cable 33.

[0051] Specifically, a wheel 621 is rotatably connected to the shaking generator 62, and a slot 622 is opened on the wheel 621. The wheel 621 rotates rapidly to convert external mechanical energy into the rotational motion of the rotor inside the shaking generator 62, thereby generating current to provide power for the electric push rod 63. When the wheel 621 rotates slowly, the current generated by the mechanical energy is small due to low power and is insufficient to start the electric push rod 63.

[0052] Furthermore, the cable 33 passes through the U-shaped plate 61, and the cable 33 is set in the groove 622. As the cable 33 is driven, the wheel 621 rotates accordingly, and the push rod 64 is set in a semicircular shape. The shaking generator 62, the wheel 621, the groove 622, the electric push rod 63 and the push rod 64 are all provided with two and are symmetrically arranged.

[0053] As can be seen from the above, when the whole device suddenly falls during the lifting process, the rotation speed of the rotating wheel 621 increases due to the excessively fast descending speed. Since the cable 33 is arranged in the slot 622 opened on the rotating wheel 621, the rotating wheel 621 rotates along with the drive of the cable 33. The rotating wheel 621 rotates rapidly to convert the external mechanical energy into the rotational motion of the rotor inside the shaking generator 62, thereby generating current, so that the shaking generator 62 generates electricity and provides power for the two electric push rods 63. The two push rods 64 on the output ends of the two electric push rods 63 are pushed out. The end of the push rod 64 is semicircular, which squeezes the cable 33 and locks it under the action of the U-shaped plate 61 and the push rod 64 to prevent the entire device from continuing to fall, ensuring the safe operation of the elevator, avoiding production interruptions due to equipment failure, ensuring the continuity and stability of production, and effectively preventing the coke tank 2 from falling from a high altitude, significantly improving construction safety. When the elevator is working normally, the cable 33 is lifted slowly, which causes the wheel 621 to rotate slowly. The current generated by the mechanical energy due to low power is small and is not enough to drive the electric push rod 63 to start.
