Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a protective device for a round manhole door on the top of an electrostatic dust collector. Background Art

[0002] Publication No. CN212882961U discloses a safety protection device for a manhole door of an electrostatic precipitator. By rotating the travel bolt, the travel bolt can be adjusted to a reasonable travel position, so that the travel bolt and the travel head of the travel switch are in contact with each other, which is highly flexible, thereby achieving the purpose of interlocking. By providing a rubber sleeve, the rubber sleeve can absorb the impact force transmitted by the travel bolt, thereby preventing the travel switch from being hit and playing a buffering role, thereby increasing the service life of the travel switch. However, the patent still has the following problems in actual use:

[0003] By providing a rubber sleeve, the rubber sleeve can absorb the impact force transmitted by the travel bolt. When the rubber sleeve is mounted on the travel switch, it cannot buffer all the impact force, but can only buffer a small part of the impact force to a certain extent. This will cause most of the impact force transmitted by the travel bolt to be borne by the travel switch at all times. This not only fails to provide buffering protection for the travel switch, but also causes the rubber sleeve to be in contact with the travel bolt for a long time, resulting in damage, thereby increasing costs.

[0004] A protective device for a circular manhole door on the top of an electrostatic precipitator is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a protective device for a circular manhole door on the top of an electrostatic precipitator, so as to solve the problem proposed in the above background technology that a rubber sleeve is currently provided, and the rubber sleeve can absorb the impact force transmitted by the travel bolt. When the rubber sleeve is sleeved with the travel switch, the rubber sleeve cannot buffer all the impact force, and can only buffer a small part of the impact force to a certain extent. This will make most of the impact force transmitted by the travel bolt always borne by the travel switch. This not only fails to buffer and protect the travel switch, but also causes the rubber sleeve to be damaged due to long-term contact with the travel bolt, thereby increasing the cost.

[0006] To achieve the above object, the utility model provides the following technical solutions: a protective device for a round manhole door on the top of an electrostatic precipitator, a galvanized angle steel bracket, a galvanized bolt and a galvanized cross bolt, wherein the galvanized angle steel bracket is threadedly connected with the galvanized bolt;

[0007] One side surface of the galvanized cross bolt is threadedly connected with a galvanized channel steel, one side surface of the galvanized channel steel is provided with a travel switch, and support columns are symmetrically installed on both sides of the top surface of the travel switch;

[0008] Also includes:

[0009] A buffer component is provided on the top surface of the support column;

[0010] The buffer assembly includes a bottom plate fixedly connected to the travel switch, a connection block is symmetrically mounted on the top surface of the bottom plate, and a placement groove is provided inside the connection block;

[0011] A sliding rod is fixedly installed inside the placement groove, and blocking plates are connected through both sides of the surface of the sliding rod, and a first spring is fixedly connected to one side surface of the blocking plate.

[0012] Preferably, a damping sleeve is fixedly connected to a surface of a side of the first spring away from the blocking plate, and a rotating shaft is fixedly connected to a top surface of the damping sleeve.

[0013] Preferably, a movable rod is rotatably connected to the top surface of the rotating shaft, a rotating shaft is rotatably connected to the top surface of the movable rod, and a rubber plate is fixedly connected to the top surface of the rotating shaft.

[0014] Preferably, a rubber block is fixedly connected in the middle of the bottom surface of the rubber plate.

[0015] Preferably, a plurality of telescopic rods are fixedly mounted around the top surface of the bottom plate, and a second spring is sleeved on the surface of the telescopic rods.

[0016] Preferably, the top surface of the second spring is fixedly connected to the rubber plate, the bottom surface of the second spring is fixedly connected to the bottom plate, and the top surface of the telescopic rod is fixedly connected to the rubber plate.

[0017] Preferably, the travel switch is fixedly connected to the galvanized channel steel by means of galvanized cross bolts.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the protective device for the round manhole door on the top of the electrostatic precipitator is provided with a buffer component, so that the distance between the bolt and the travel switch contact can be automatically adjusted by twisting the galvanized bolt up and down, so that when the galvanized bolt contacts the travel switch, a buffer protection can be provided for the end of the travel switch, thereby reducing the impact force of the galvanized bolt on the end of the travel switch, thereby increasing the service life of the travel switch. The specific contents are as follows:

[0019] 1. By setting a buffer component, when the galvanized bolt descends, the rubber plate will be squeezed and descended. When the rubber plate descends, the movable rod will be driven to rotate with the rotating shaft as the center point, so that the rotation of the movable rod can push the damping sleeve, and the movement of the damping sleeve can squeeze the first spring, so that the first spring is deformed. At the same time, the rubber plate descends, so that the telescopic rod and the second spring can be driven to descend, so that the rubber plate can be buffered for the second time, so that the impact force generated when the galvanized bolt descends can be better buffered, so as to avoid the galvanized bolt from having too much impact on the travel switch, resulting in damage to the travel switch;

[0020] 2. By setting galvanized angle steel brackets, galvanized bolts, galvanized cross bolts, galvanized channel steel and travel switches, the staff can automatically adjust the distance between the bolts and the travel switch contacts by twisting the galvanized bolts up and down, thereby making contact with the travel switch. The travel switch is then electrically interlocked with the high-voltage power supply on the top of the dust collector, so that the high-voltage power supply stops working, and the high-voltage direct current is cut off inside the electric field. The staff can safely enter the electric field, thereby achieving the protection of the construction personnel and maintenance personnel entering the electric field. BRIEF DESCRIPTION OF THE DRAWINGS

By mechanically opening a hole on the galvanized angle steel bracket and then threading it with the galvanized bolt, the distance between the bolt and the travel switch contact can be automatically adjusted by twisting the galvanized bolt up and down, so that it contacts the travel switch, and the travel switch is electrically interlocked with the high-voltage power supply on the top of the dust collector.
