The invention has the following beneficial effects:
(1) the slide and the guide rail that bear the weight of the pump body are not fixed connection, but the joint is on the guide rail, and the pump body also does not have the snap-on in the design platform, when changing or maintaining the pump, only need withdraw from the effort of fixed slide in the design platform outside, conveniently shifts out the pump to the outside maintenance of design platform or change, and does not need the maintenance personal to enter into and maintain in the narrow and small design platform, has reduced the degree of difficulty of maintenance or change pump.
(2) The bottom of slide is provided with direction boss and limiting plate, and the direction boss can be guaranteed that the slide removes along the guide rail direction, prevents that the skew from taking place at the in-process position that removes, and the limiting plate makes slide bottom card in the inslot of guide rail, can prevent to drop from the guide rail at the in-process slide that removes. In addition, when the pump is in a working state, the pump is shaken continuously, and the limiting plate can prevent the shaken pump from driving the sliding plate to fall off from the guide rail.
(3) The clamping groove of the limiting clamping plate and the contact surface of the sliding plate, which are mutually attached, are inclined planes. When the limiting clamping plate clamps the sliding plate, the sliding plate only needs to be moved a small distance slightly when needing to be moved outwards, the sliding plate is not in contact with the clamping groove any more, the sliding plate can be conveniently moved continuously at the back, and the effect of quick loading and unloading is achieved.
After the primary fixed position of the limiting clamping plate, the position of the pump in the sizing table does not need to be repeatedly determined when the pump is replaced or maintained every time, the sliding plate bearing the pump body cannot continuously move when moving to the limiting clamping plate, and the position is the designated position of the pump in the sizing table.
Set up the clearance between spacing cardboard and the slide, let wedge-shaped spacing cardboard inclined plane and slide inclined plane contact, play the effect of compressing tightly. But the vacuum pump can shake during operation, so that the fixed plate is pressed through the inclined plane of the wedge-shaped limiting clamping plate and the elbow clamp, and the fixed plate becomes stable.
(4) The elbow presss from both sides the setting in the position department that is close to design platform entry, and when changing or maintenance pump, the staff need not enter into the inside elbow of just can removing press from both sides the pressure to the slide of design platform, removes this pressure, and the staff just can move the outside maintenance or the change of design platform with the pump very conveniently.
The inner space of the sizing table is small, the pump is not allowed to be replaced inside the sizing table, workers are difficult to enter the sizing table, the pump is moved to the outside for maintenance or replacement, and the working difficulty is reduced.
(5) The cooperation that adopts public head of handle formula quick change and handle formula quick change female head uses and can realize the quick connection or the dismantlement of the pump body and equipment hose, and then convenient quick maintains or changes the pump body.
(6) Stopper and spacing cardboard are mutually supported, and the fixed pump body that can be better is in the position of design platform, and the skew takes place for the pump body position that prevents the shake. When the bolt that leads to fixed spacing cardboard rotated because the shake of the pump body, because the length of the slide along the guide rail moving direction of stopper is greater than the groove width of guide rail for even the pump body shake, because stopper and bolt fixed connection, the stopper also can prevent not hard up bolt rotation, and then fixes spacing cardboard, finally realizes fixing the purpose of slide.
(7) The upper end of the C-shaped guide rail is a horizontal supporting surface, so that the guide rail and the sliding plate form surface contact, and the firmness of the pump body arranged on the sliding plate can be improved.
(8) The hook point portion of the guide rail of C type is down, and the limiting plate of slide is located the below of hook point portion, and the limiting plate width is greater than the distance between two hook point portions, slightly is less than or equal to the groove width of guide rail again, installs the pump body on the slide when the state of opening, has strong vibrations, limiting plate and the relevant cooperation of guide rail, the position of fixed slide that can be better, and then the better position of fixing the pump body.
