This technical scheme can realize the raising and lowering functions of reel to make things convenient for the staff to carry out the maintenance change operation of arbitrary one deck screen cloth, convenient and fast.
Description
Technical Field
The utility model belongs to rocking sieve equipment field relates to a elevating gear on rocking sieve particularly.
Background
In the actual production of utilizing the rocking screen to carry out material screening, often need to maintain or change its inside screen cloth. However, in the prior art, when the lower screen is replaced, a worker often needs to detach the screen frame of the swing screen layer by layer from top to bottom so as to replace the required screen, which brings great inconvenience to the worker.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a can realize reel raising and lowering functions in order to conveniently change the elevating gear on the rocking sieve of lower part screen cloth.
The utility model discloses a task is accomplished like this, along 3 mounts of the lower bottom surface edge equipartition of bottommost reel, the cylinder upper end is fixed on this mount, and the lower extreme passes through the trachea and links to each other with the air supply piston rod middle part on the cylinder slides and is fixed with the top and holds the piece, and one side on the grip block is opened has the adjustment tank and sets up the slot hole in this adjustment tank both sides, and this grip block is through wearing the bolt fastening in two slot holes on the top hold the piece, the piston rod passes the adjustment tank, on this grip block the opposite side with bottom surface contact under the reel border on the reel, the fixed block is fixed at the top of piston rod and passes through bolt fixed connection with the dust cover.
One side of the clamping plate, which is positioned below the edge of the screen frame, is an arc surface, and the radius of the arc surface is the same as that of the screen frame.
The utility model discloses has following effect: this technical scheme adopts cylinder and top to hold piece, grip block mutually supporting mode, can realize the raising and lowering functions of reel to make things convenient for the staff to carry out the maintenance change operation of arbitrary one deck screen cloth, convenient and fast.
Drawings
FIG. 1 is a front view of the present invention; FIG. 2 is a schematic diagram of a clamping plate structure.
Description of the drawings: 1. a screen frame; 11. the edge of the screen frame; 2. a fixed mount; 3. a cylinder; 4. a piston rod; 5. a jacking block; 6. a clamping plate; 61. an adjustment groove; 62. a long hole; 7. a fixed block; 8. a dust cover; 9. and (4) a gas source.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1-2, in a lifting device on a swing sieve, 3 fixing frames 2 are uniformly distributed along the lower bottom edge of a bottommost sieve frame 1, the upper end of a cylinder 3 is fixed on the fixing frame 2, the lower end of the cylinder is connected with an air source 9 through an air pipe, a jacking block 5 is fixed in the middle of a piston rod 4 on the cylinder 3 in a sliding manner, an adjusting groove 61 and long holes 62 arranged at two sides of the adjusting groove 61 are formed in one side of a clamping plate 6, the clamping plate 6 is fixed on the jacking block 5 through bolts penetrating through the two long holes 62, the piston rod 4 penetrates through the adjusting groove 61, the other side of the clamping plate 6 is in contact with the lower bottom of a sieve frame edge 11 on the sieve frame 1, and a fixing block 7 is fixed at the top of the piston rod 4 and is fixedly connected with a dust cover 8 through. The above-mentioned top supporting block 5 is fixed on the long hole 62 of the clamping plate 6 by means of bolt, so that the distance between the clamping plate 6 and the screen frame 1 can be regulated, and the screen frame to be lifted can be selected.
One side of the clamping plate 6, which is positioned below the edge 11 of the screen frame, is an arc surface, and the radius of the arc surface is the same as that of the screen frame 1. The cambered surface in 3 grip blocks 6 centre gripping jointly is in the outside of reel 1, makes the reel more stable in the lifting.
When a worker needs to replace a certain layer of screen mesh on the lower part in the swing screen, the position of the clamping plate 6 relative to the jacking block 5 is adjusted firstly to avoid interference with the screen frame edge 11, then the positions of the jacking block 5 and the clamping plate 6 on the piston rod 4 are adjusted, when the clamping plate moves to the upper screen frame edge 11 of the upper layer of screen mesh needing to be replaced, the jacking block 5 is fixed, the clamping plate 6 is moved to contact with the lower surface of the screen frame edge 11, then the air source 9 is started to enable each air cylinder 3 to work, and each layer of screen frame and dust cover above the layer of screen mesh needing to be replaced are lifted. At this moment, the staff can change the screen cloth operation through this lifting clearance.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
