Abstract
Description
Technical Field
[0001] The utility model relates to a device for conveniently replacing a porcelain bottle of an insulating box, belonging to the technical field of coking. Background Art
[0002] In the coking industry, electric tar precipitators are used to purify coke oven gas. The operating voltage of electric tar precipitators is generally around 45KV. Affected by the high voltage, the porcelain bottles of the insulation box often discharge and break down. At this time, the porcelain bottles of the insulation box need to be replaced. The porcelain bottle hanger serves as the anchor point for supporting the entire electric field suspension. Traditional porcelain bottle replacement requires the electric tar precipitator to be shut down, and the operator enters the inside of the electric tar precipitator and uses a lifting tool to support the suspension. Because there are flammable, explosive, toxic and harmful media such as carbon monoxide, hydrogen, and methane in the coke oven gas, it brings great safety hazards to entering the internal operation, which is often prone to poisoning, suffocation, fire and explosion, so there are great disadvantages.
[0003] Chinese patent (CN209906252U) discloses an insulating porcelain bottle hanging rod, including a base, a horizontal support rod, and a lifting assembly; the horizontal support rod is movably connected to the base, and rotates with the connection point between the horizontal support rod and the base as a fulcrum, and a pulley is provided at one end of the horizontal support rod; the lifting assembly includes a lifting rope, which passes through the horizontal support rod after passing through the pulley, and a hook is connected to the end of the lifting rope, and the other end of the lifting rope is wound around the wheel axle assembly, and the wheel axle assembly includes a wheel axle, and the rotation of the wheel axle drives the hook to move up and down. After the lifting device of the utility model is installed on the installation component, the lever principle and the pulley principle are used to lift the porcelain bottle to the desired position through the pulley and the lifting rope.
[0004] When the above patent is working, the base is first fixed on the mounting component, and then the vertical support rod is always held or the vertical support rod is mounted on other frames, which is inconvenient to operate and has a complex structure, thereby increasing production costs. Utility Model Content
[0005] The technical problem to be solved by the utility model is: to overcome the shortcomings of the prior art and provide a device for conveniently replacing the porcelain bottle of the insulating box, which has a simple structure, is easy to use, and reduces the production cost, and realizes operation outside the insulating box of the electric tar precipitator, that is, the operator does not need to enter the inside of the electric tar precipitator to support the electric field suspension and adjust the suspension height, thereby reducing the risk of entering the inside of the electric tar precipitator for operation and eliminating safety hazards.
[0006] The utility model discloses a device for conveniently replacing a porcelain bottle of an insulating box, comprising a hook assembly and an adjusting assembly, wherein the hook assembly is disposed at the head end of the adjusting assembly and is hinged to the adjusting assembly, and the tail end of the adjusting assembly is fixedly connected to the platform;
[0007] The adjustment assembly includes an extension arm, a first adjustment rod, a second adjustment rod, a tensioner and a fulcrum. The middle part of the extension arm is hinged to the fulcrum, one end of the extension arm is hinged to the hook assembly, and the other end is hinged to the first adjustment rod. One end of the second adjustment rod is fixed to the platform, and the other end is connected to the first adjustment rod through the tensioner. The tensioner can adjust the distance between the first adjustment rod and the second adjustment rod.
[0008] By setting a tensioner, the first adjusting rod and the second adjusting rod can be moved closer to or farther from each other, thereby realizing the up and down movement of the first adjusting rod. The up and down movement of the first adjusting rod is like a person pulling one end of the extension arm by hand. By setting a fulcrum in the middle of the extension arm and hinged to the fulcrum, the up and down movement of the other end of the extension arm can be realized, thereby driving the up and down movement of the hook assembly. The end of the hook assembly is clamped with the connecting rod on the suspension, thereby raising or lowering the height of the electric field suspension.
[0009] The tensioner is sleeved on the outer circumference of the first adjustment rod and the second adjustment rod, and the tensioner is connected to the first adjustment rod and the second adjustment rod by threads, and the threads on the first adjustment rod and the second adjustment rod are screwed in opposite directions. By screwing the tensioner, the first adjustment rod and the second adjustment rod are moved in a direction of approaching or moving away from each other, and the lifting and lowering of the hook assembly can be realized only by screwing, and the operation is simple.
[0010] The distance between the fulcrum and the hook assembly is smaller than the distance between the fulcrum and the first adjusting rod. According to the lever principle, the closer the fulcrum is to the hook assembly, the smaller the distance the first adjusting rod moves, the higher the hook assembly can be lifted, and the more labor-saving it is.
[0011] The lifting range of the hook assembly is less than 50 mm.
[0012] The hook assembly comprises a V-shaped rod and a hook, one end of the V-shaped rod is hinged with the extension arm, and the other end is fixedly connected with the hook. A protrusion is arranged on the connecting rod on the suspension, the hook hooks the connecting rod, and the protrusion prevents the hook from moving upward.
[0013] An anti-hook plate is arranged at the hook opening. After the hook is hooked on the connecting rod, the anti-hook plate seals the hook opening to prevent the hook from being separated from the connecting rod, thereby ensuring a safe and reliable working process.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] (1) The utility model sets a tensioner to achieve the first adjustment rod and the second adjustment rod to move closer to or farther from each other, thereby achieving the up and down movement of the first adjustment rod. The up and down movement of the first adjustment rod is like a person pulling one end of the extension arm by hand. By setting a fulcrum in the middle of the extension arm and hinged with the fulcrum, the up and down movement of the other end of the extension arm is achieved, thereby driving the up and down movement of the hook assembly. The end of the hook assembly is engaged with the connecting rod on the suspension, thereby raising or lowering the height of the electric field suspension. It is possible to operate outside the insulation box of the electric tar collector, that is, the operator does not need to enter the inside of the electric tar collector to support the electric field suspension and adjust the height of the suspension, reducing the risk of entering the inside of the electric tar collector to operate and eliminating safety hazards.
[0016] (2) The tensioner is sleeved on the outer circumference of the first adjustment rod and the second adjustment rod, and the tensioner is connected to the first adjustment rod and the second adjustment rod by threads, and the threads on the first adjustment rod and the second adjustment rod are screwed in opposite directions. By screwing the tensioner, the first adjustment rod and the second adjustment rod are moved in a direction of approaching or moving away from each other, and the lifting and lowering of the hook assembly can be realized only by screwing, which is simple to operate.
[0017] (3) The distance between the fulcrum and the hook assembly is smaller than the distance between the fulcrum and the first adjusting rod. According to the lever principle, the closer the fulcrum is to the hook assembly, the smaller the distance the first adjusting rod moves, the higher the hook assembly can be lifted, and the more labor-saving it is.
[0018] (4) An anti-hook plate is provided at the hook opening. After the hook is hooked onto the connecting rod, the anti-hook plate seals the hook opening to prevent the hook from being detached from the connecting rod, thus ensuring a safe and reliable working process.
