Abstract
Description
[Technical field]
[0001] The utility model relates to the technical field of electric precipitators, in particular to a fixing device for a grid plate of an electric precipitator platform. [Background technology]
[0002] At present, the grid plates on the electrostatic precipitator are often installed on the platform frame. The platform frame is usually made of channel steel. The installation methods include intermittent welding around the grid plate and fixing the grid plate with installation clips at the four corners. For grid plates that do not need to be disassembled, they can be welded to the platform frame. For grid plates that need to be temporarily removed during maintenance, they are fixed with installation clips. At least four installation clips should be used for each plate, and upper clamps and bolt spot welding are commonly used.
[0003] The grid plates of electrostatic precipitators are usually made of carbon steel or stainless steel, and are hot-dip galvanized as a whole. The grid plates are installed on a platform frame made of channel steel, and the platform frame is hot-dip galvanized as a whole. Both the grid plates and the frame can be prevented from oxidation.
[0004] Defects of the original technical solution: When welding or clamping and bolt spot welding is used, the galvanized layer on the grid plate and platform frame will be damaged, causing corrosion in the later stage. The welding method cannot be removed during maintenance and can only be broken apart. The clamping and bolt spot welding method cannot withstand long-term vibration loads and will cause the mounting clamp to fall off. [Contents of the utility model]

[0007] Preferably, the pressing member further comprises a groove-shaped body, and the free ends of two groove walls of the groove-shaped body are bent to form hooks.
[0008] Preferably, a support sleeve is provided on the bolts between the channel body and the channel steel.
[0009] Preferably, a pad located on the inner side of the upper channel wall of the channel steel is sleeved on the bolt, and the upper end of the pad is consistent with the inner side of the upper channel wall of the channel steel.
[0010] Beneficial effects of the utility model: the utility model provides bolt holes on the upper channel wall of the channel steel, bolts are inserted into the bolt holes, and a clamping piece and a threaded nut are sleeved on the bolt. The clamping piece is screwed into the nut to clamp and fix the grid plate placed on the channel steel. The clamping piece includes two hooks, which are respectively hung on the corresponding grid plates of the grid plate. Compared with the prior art, the utility model can avoid the disadvantages caused by welding, has the advantages of impact load resistance and safe fastening, and has a fast installation and fastening speed.
[0011] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.
Brief Description of the Drawings
[0012] Figure 1 The utility model is a structural schematic diagram of a fixing device for a grid plate of an electrostatic precipitator platform.
[0013] In the figure: 1-channel steel, 2-bolt, 3-nut, 4-pressing piece, 5-bolt hole, 6-grid plate, 7-support sleeve, 8-pad, 41-hook, 42-trough body, 61-grid plate. [Specific implementation method]
[0014] See also Figure 1 The utility model discloses a fixing device for a grid plate of an electrostatic precipitator platform, comprising a channel steel 1, a bolt 2, a nut 3 and a clamping member 4. A bolt hole 5 is provided on the upper groove wall of the channel steel 1, and a bolt 2 is inserted into the bolt hole 5. A clamping member 4 and a nut 3 connected by threading are sleeved on the bolt 2. The clamping member 4 is screwed into the nut 3 to clamp and fix the grid plate 6 placed on the channel steel 1. The clamping member 4 comprises two hooks 41, and the two hooks 41 are respectively hung on the corresponding grid plates 61 of the grid plate 6. The clamping member 4 also comprises a groove body 42, and the free ends of the two groove wall bodies of the groove body 42 are bent to form the hook 41. A supporting sleeve 7 is sleeved on the bolt 2 between the groove body 42 and the channel steel 1, and a pad 8 located on the inner side of the upper groove wall of the channel steel 1 is sleeved on the bolt 2. The upper end of the pad 8 is consistent with the inner side of the upper groove wall of the channel steel 1.
[0015] Working process of this utility model:
[0016] The utility model discloses a device for fixing a grid plate of an electrostatic precipitator platform. During operation, the bolt 2 is passed through the cushion block 8, the bolt hole 5, the support sleeve 7 and the clamping piece 4 in sequence, the two hooks 41 of the clamping piece 4 are respectively hung on the corresponding grid plates 61 of the grid plate 6, and then the nut 3 is screwed onto the bolt 2. The clamping piece 4 is screwed into the nut 3 to clamp and fix the grid plate 6 placed on the channel steel 1.
[0017] The support sleeve 7 supports the clamping member 4, improves the fixing reliability of the clamping member 4, and reduces the requirement of the clamping member 4 on the strength of the raw materials; in addition, it prevents the nut 3 from being screwed in too hard, which may cause deformation and damage to the clamping member 4.
[0018] When the grid plate 6 is disassembled, the nut 3 is loosened to a certain extent until the pressing member 4 can be pulled upward to a certain height and the pressing member 4 can be rotated 90 degrees so that it does not block the grid plate 61, and then the grid plate 6 can be disassembled. There is no need to remove the nut 3 and the pressing member 4 from the bolt 2, so the operation is convenient and quick.
[0019] When the grid plate 6 is assembled, the support of the support sleeve 7 for the clamping piece 4 limits the descent of the clamping piece 4 (if there is no support from the support sleeve 7, the clamping piece 4 will descend to a greater height, so that the clamping piece 4 is completely sunk into the grid of the grid plate 6, making it inconvenient to manually pull the clamping piece 4). This makes it convenient to manually pull the clamping piece 4 and rotate it 90 degrees, and then tighten the nut 3 to clamp and fix the grid plate 6 placed on the channel steel 1.
[0020] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
