Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a support base for a blast furnace charging belt conveyor. Background Technology

[0002] The blast furnace charging belt conveyor is an important piece of equipment used in blast furnace ironmaking to transport raw materials to the top of the blast furnace. It uses a rubber belt as the traction and load-bearing component. The conveyor belt forms a closed loop through drive, redirection, and tensioning rollers. The upper and lower branches of the conveyor belt are supported on idlers, and tension is provided by the tensioning device. During operation, the friction between the drive roller and the rubber belt drives the belt to run. The material is continuously unloaded onto the belt by the feeding device and then transported. It has the characteristics of large conveying capacity and continuous stability, and can meet the raw material supply needs of efficient and continuous blast furnace smelting.

[0003] However, after the blast furnace charging belt conveyor has been running for a long time, its support frame is fixed with bolts. Frequent material impact and mechanical vibration will aggravate the wear of the support frame components and reduce the structural stability. The bolts are subjected to alternating stress for a long time, which can easily lead to problems such as corrosion and stripped threads. If they are not disassembled and maintained in time, the bolts will become less tough and more brittle, eventually leading to breakage. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where, after a long period of operation, the support frame of the blast furnace charging belt is fixed with bolts. Frequent material impacts and mechanical vibrations will aggravate the wear of the support frame components, reduce structural stability, and the bolts are subject to alternating stress for a long time, which can easily lead to problems such as corrosion and thread stripping. If not disassembled and maintained in time, the bolts will become less tough and more brittle, eventually leading to breakage. Therefore, a support seat for a blast furnace charging belt is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a support base for a blast furnace charging belt conveyor, comprising a frame and a replacement device. A transmission belt is fitted onto the surface of the frame, and a support frame is provided on the lower surface of the frame. The replacement device is located on the lower surface of the frame and includes an mounting sleeve fixedly connected to the frame. A slot is formed on the inner wall of the mounting sleeve. A sliding hole is formed on the upper surface of the support frame, and a sliding plate is slidably connected to the inner wall of the sliding hole on the upper surface of the support frame. A clamping plate is fixedly connected to the upper surface of the sliding plate, and the clamping plate is triangularly arranged. The clamping plate is connected to the mounting sleeve... The surface features a slotted engagement mechanism. A baffle is fixedly connected to one side of the slide plate, and a fixing spring is fixedly connected to one side of the baffle. The side of the fixing spring away from the baffle is fixedly connected to the support frame. By setting up a replacement device, the efficiency and convenience of disassembling and assembling the support frame are greatly improved. When a worn support frame needs to be replaced, simply pull the slide plate to disengage the clamp from the slot, and the support frame can be easily pulled down to complete the disassembly. Unlike the traditional bolt fixing method, this reduces downtime caused by support frame replacement, improves production efficiency, and at the same time reduces the disassembly difficulties and safety hazards caused by bolt breakage, thus lowering maintenance costs and operational risks.

[0006] Preferably, there are two clamping plates, which are symmetrically arranged. After the clamping plates are inserted into the mounting sleeve, the elastic force generated by the fixing spring squeezes the clamping plates, and the round wheel drives the sliding plate to move, so that the clamping plates are tightly abutted against the slots, and the support frame is firmly fixed in the designated position, thereby ensuring the stability and reliability of the installation of the support frame under the blast furnace charging belt.

[0007] Preferably, a rotating rod is fixedly connected to the lower surface of the skateboard, and a wheel is rotatably connected to the surface of the rotating rod. By setting the wheel, when the skateboard is pulled to disengage the clamp from the slot and remove the support frame, the wheel can reduce the friction during the movement of the skateboard, making the disassembly operation smoother and less strenuous.

[0008] Preferably, the wheel contacts the support frame, and the longitudinal section of the baffle is arranged in an "L" shape.

[0009] Preferably, the lower surface of the support frame is provided with a buffer assembly, the buffer assembly including a column, the column being slidably connected to the support frame, a connecting rod being fixedly connected to the surface of the column, a push rod being fixedly connected to the upper surface of the connecting rod, and a damper being fixedly connected to the lower surface of the support frame. By setting the buffer assembly, the stability of the equipment during operation is effectively enhanced, the impact of vibration on material transportation is reduced, material spillage or accumulation due to vibration is prevented, the continuity and accuracy of material conveying are ensured, the equipment failure rate is reduced, and the overall operational safety is improved.

[0010] Preferably, the push rod is slidably connected to the damper, and the damper is located on the upper surface of the connecting rod. By setting the push rod, when the column is subjected to external forces such as material impact and mechanical vibration during the operation of the blast furnace charging belt, the push rod will be squeezed, and the push rod will then slide.

[0011] Preferably, a pressure spring is fitted on the surface of the push rod, and the two ends of the pressure spring are fixedly connected to the damper and the push rod respectively. By setting the pressure spring, when the column is subjected to force, the push rod is squeezed and slid. The pressure spring and the damper work together. It absorbs and stores energy through its own compression deformation, and converts the externally applied impact force into elastic potential energy, thereby slowing down the sliding speed of the push rod and reducing rigid collisions.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a replacement device, pulling the slide plate causes the clamping plate to disengage from the slot, and then pulling down the support frame, the support frame can be removed. When the clamping plate is inserted into the mounting sleeve, the clamping plate is released, the fixing spring loses its restraint and generates elastic force to squeeze the clamping plate, the wheel drives the slide plate to move, and the slide plate causes the clamping plate to abut against the slot. At this time, the support frame is fixed. By setting a replacement device, the efficiency and convenience of disassembly and assembly of the support frame are greatly improved. When it is necessary to replace the worn support frame, simply pull the slide plate to disengage the clamping plate from the slot, and the support frame can be easily pulled down to complete the disassembly. Unlike the traditional bolt fixing method, it does not require the downtime caused by support frame replacement, thus improving production efficiency. At the same time, it reduces the disassembly difficulties and safety hazards caused by bolt breakage, and lowers maintenance costs and operational risks.

[0014] 2. In this utility model, by setting a buffer component, when the column is subjected to force, it squeezes the push rod. The push rod slides and cooperates with the damper and pressure spring to buffer the pressure, thereby reducing the vibration of the equipment, increasing the stability of the equipment, reducing the impact of vibration on material transportation, and effectively enhancing the stability of the equipment during operation by setting the buffer component. It also reduces the impact of vibration on material transportation, prevents materials from spilling or accumulating due to vibration, ensures the continuity and accuracy of material transportation, reduces the equipment failure rate, and improves the overall operational safety.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a support base for a blast furnace charging belt conveyor, including a frame 1 and a replacement device 4. A transmission belt 2 is sleeved on the surface of the frame 1, a support frame 3 is provided on the lower surface of the frame 1, and the replacement device 4 is provided on the lower surface of the frame 1.

[0022] In this implementation scheme: the replacement device 4 includes a mounting sleeve 41, which is fixedly connected to the frame 1. The inner wall of the mounting sleeve 41 has a slot, and the upper surface of the support frame 3 has a sliding hole. A sliding plate 43 is slidably connected to the inner wall of the sliding hole on the upper surface of the support frame 3. A clamping plate 42 is fixedly connected to the upper surface of the sliding plate 43. The clamping plate 42 is triangular in shape and engages with the slot on the surface of the mounting sleeve 41. A baffle 44 is fixedly connected to one side of the sliding plate 43, and a fixing spring 47 is fixedly connected to one side of the baffle 44. The side of the fixing spring 47 away from the baffle 44 is fixedly connected to the support frame 3. By setting the replacement device 4, the disassembly and assembly efficiency and convenience of the support frame 3 are greatly improved. When it is necessary to replace the worn support frame 3, it is only necessary to pull the sliding plate 43 to drive the clamping plate 42 out of the slot, and the support frame 3 can be easily pulled down to complete the disassembly. Unlike the traditional bolt fixing method, it does not require the downtime caused by the replacement of the support frame 3, thus improving production efficiency. At the same time, it reduces the disassembly difficulties and safety hazards caused by bolt breakage, and lowers maintenance costs and operational risks.

[0023] Specifically, there are two clamping plates 42, which are symmetrically arranged. After the clamping plates 42 are inserted into the mounting sleeve 41, the elastic force generated by the fixing spring 47 squeezes the clamping plates 42. The wheel 46 drives the sliding plate 43 to move, causing the clamping plates 42 to abut tightly against the slot, thus firmly fixing the support frame 3 in the designated position, thereby ensuring the stability and reliability of the installation of the support frame 3 under the blast furnace charging belt.

[0024] Specifically, a rotating rod 48 is fixedly connected to the lower surface of the slide plate 43, and a wheel 46 is rotatably connected to the surface of the rotating rod 48. By setting the wheel 46, when the slide plate 43 is pulled to drive the clamp 42 out of the slot to disassemble the support frame 3, the wheel 46 can reduce the friction during the movement of the slide plate 43, making the disassembly operation smoother and less strenuous.

[0025] Specifically, the wheel 46 contacts the support frame 3, and the longitudinal section of the baffle 44 is set in an "L" shape.

[0026] Specifically, a buffer assembly 45 is provided on the lower surface of the support frame 3. The buffer assembly 45 includes a column 451, which is slidably connected to the support frame 3. A connecting rod 452 is fixedly connected to the surface of the column 451, and a push rod 454 is fixedly connected to the upper surface of the connecting rod 452. A damper 453 is fixedly connected to the lower surface of the support frame 3. By setting the buffer assembly 45, the stability of the equipment during operation is effectively enhanced, the impact of vibration on material transportation is reduced, the material is prevented from spilling or accumulating due to vibration, the continuity and accuracy of material transportation are ensured, the equipment failure rate is reduced, and the overall operational safety is improved.

[0027] Specifically, push rod 454 is slidably connected to damper 453, and damper 453 is located on the upper surface of connecting rod 452.

[0028] In this embodiment: by setting push rod 454, when column 451 is subjected to external forces such as material impact and mechanical vibration during the operation of blast furnace charging belt, it will squeeze push rod 454, and push rod 454 will then slide.

[0029] Specifically, a pressure spring 455 is fitted onto the surface of the push rod 454, and the two ends of the pressure spring 455 are fixedly connected to the damper 453 and the push rod 454, respectively.

[0030] In this embodiment: by setting a pressure spring 455, when the column 451 is subjected to force, the push rod 454 is squeezed and slid. The pressure spring 455 works in conjunction with the damper 453. It absorbs and stores energy through its own compression deformation, converting the externally applied impact force into elastic potential energy, thereby slowing down the sliding speed of the push rod 454 and reducing rigid collisions.

[0031] Working principle: By setting the replacement device 4, the sliding plate 43 is pulled to disengage the clamping plate 42 from the slot, and then the support frame 3 is pulled down to remove it. When the clamping plate 42 is inserted into the mounting sleeve 41, the clamping plate 42 is released, the fixing spring 47 loses its restraint and generates elastic force to squeeze the clamping plate 42. The wheel 46 drives the sliding plate 43 to move, and the sliding plate 43 drives the clamping plate 42 to abut against the slot. At this time, the support frame 3 is fixed. By setting the replacement device 4, the efficiency and convenience of disassembling and assembling the support frame 3 are greatly improved. When it is necessary to replace the worn support frame 3, simply pull the sliding plate 43 to disengage the clamping plate 42 from the slot, and the support frame 3 can be easily pulled down to complete the disassembly. Unlike the traditional bolt fixing method, it does not require the downtime caused by the replacement of the support frame 3, thus improving production efficiency. At the same time, it reduces the disassembly difficulties and safety hazards caused by bolt breakage, and lowers maintenance costs and operational risks.

[0032] By setting up the buffer component 45, when the column 451 is under force, it squeezes the push rod 454. The push rod 454 slides and cooperates with the damper 453 and the pressure spring 455 to buffer the pressure, reduce the vibration of the equipment, increase the stability of the equipment, and reduce the impact of vibration on material transportation. By setting up the buffer component 45, the stability of the equipment during operation is effectively enhanced, the impact of vibration on material transportation is reduced, the material is prevented from spilling or accumulating due to vibration, the continuity and accuracy of material transportation are ensured, the equipment failure rate is reduced, and the overall operational safety is improved.
