Abstract
The invention discloses a device for adjusting a three-arm clamp hoisting transportation convection plate. The device comprises a coarse adjustment screw rod, a similar piston mechanism, a piston barrel, a reference plate and a movable cushion block, wherein the upper end of the piston barrel is closed, and an opening is formed in the lower end of the piston barrel; a positioning nut is arranged on the inner wall of the upper end of the piston barrel; one end of the coarse adjustment screw rod penetrates through the positioning nut, extends into the inner cavity of the piston barrel and is connected with the similar piston mechanism; the bottom of the similar piston mechanism is fixedly connected with the reference plate; two ends of the reference plate are connected with the movable cushion block through fine adjustment bolts. The adjustment device is suitable for hoisting transportation of three types of convection plates with different thicknesses during bell furnace production; the phenomenon that a jaw and the edge of the convection plate are locked or are clamped to the convection plate on the lower layer due to improper perpendicular height between the jaw and the cushion block is avoided; the convection plate hoisting time is shortened, the convection plate hoisting transportation safety is improved, labor is saved, the risk is reduced, and the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of control apparatus, specifically three arm clamp handling convection-plate control apparatuss.
Background technology
Handling three class different-thickness convection-plate when taking in bell furnace production process, fixing welding cushion block makes three arm clamps compatible not enough to multiple convection-plate handling, when handling, jaw is easy and convection-plate edge is stuck, need manually to pry open with crowbar etc., labour intensity is large, dangerous high, postponement production rhythm, have impact on the production economy benefit of enterprise.
Summary of the invention
The object of the present invention is to provide a kind of three arm clamp handling convection-plate control apparatuss, this control apparatus is applicable to the handling of the convection-plate of three class different-thickness in bell furnace production, avoid jaw and improper jaw and the convection-plate checkpost of causing of cushion block vertical dimension dead or snap into lower floor's convection-plate, shorten the convection-plate lifting time, improve convection-plate safe lifting, save manpower, reduced danger, improve work efficiency.
The present invention solves the technical scheme that its technical matters takes: three arm clamp handling convection-plate control apparatuss, its structure comprises coarse adjustment screw rod, class piston mechanism, piston barrel, datum plate and movable cushion block, described piston barrel upper end closed, lower ending opening, setscrew nut is provided with at the inwall of piston barrel upper end, described coarse adjustment screw rod one end is connected with class piston mechanism through extending to piston barrel inner chamber after setscrew nut, bottom and the datum plate of described class piston mechanism are connected, and are connected with movable cushion block at the two ends of datum plate by accurate adjustment bolt.
Further, described piston barrel inner chamber top is provided with upper limit, and the bottom of piston barrel inner chamber is provided with lower limit.
Further, the bottom of described class piston mechanism is welded with datum plate roof by pipe link.
Further, the upper end of described coarse adjustment screw rod is connected with crank.
The invention has the beneficial effects as follows:
1, this control apparatus is welded with respectively in the side of three extending arms of three arm clamps, during operation, according to the thickness of hung convection-plate, first rotate coarse adjustment screw rod by crank, reach regulation position of rule, then by accurate adjustment bolt adjustment movable cushion block and datum plate distance, be suitable for fine setting, reach best safety position, operation crown block will be adjusted three arm clamps and be placed on convection-plate to be hung.Avoid jaw and improper jaw and the convection-plate checkpost of causing of cushion block vertical dimension dead or snap into lower floor's convection-plate, shorten the convection-plate lifting time, improve convection-plate safe lifting, saved manpower, reduced danger, improve work efficiency.
2, be provided with upper limit on the top of piston barrel inner chamber, bottom is provided with lower limit, the scope of class piston mechanism movement can be prevented excessive, class piston mechanism is skidded off from the bottom of piston barrel, also can save regulation time, the accuracy rate of increasing work efficiency and regulating simultaneously.
3, adopt setscrew nut at piston barrel inner chamber and coarse adjustment screw rod connection mode, by being welded on setscrew nut on sleeve, coarse adjustment screw rod and sleeve produce relative displacement, realize coarse adjustment object.
4, adjust to tie by accurate adjustment spiral shell in the two ends of datum plate and movable cushion block and connect, realized the fine setting of movable cushion block by accurate adjustment bolt, make the height of movable cushion block more accurate, safer when ensureing handling convection-plate, reduce dangerous.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1 crank, 2 coarse adjustment screw rods, 3 setscrew nuts, 4 piston barrels, 5 upper limits, 6 class piston mechanisms, 7 lower limit, 8 datum plates, 9 movable cushion block, 10 accurate adjustment bolts.
Detailed description of the invention
With reference to Figure of description, three arm clamp handling convection-plate control apparatuss of the present invention are described in detail below.
As shown in Figure 1, three arm clamp handling convection-plate control apparatuss of the present invention, its structure comprises coarse adjustment screw rod 2, class piston mechanism 6, piston barrel 4, datum plate 8 and movable cushion block 9, described piston barrel 4 upper end closed, lower ending opening, is provided with setscrew nut 3 at the inwall of piston barrel 4 upper end, setscrew nut 3 is adopted at piston barrel 4 inner chamber and coarse adjustment screw rod 2 connection mode, by being welded on setscrew nut on piston barrel 4, coarse adjustment screw rod 2 and sleeve produce relative displacement, realize coarse adjustment object.Described coarse adjustment screw rod 2 one end is connected with class piston mechanism 6 through extending to piston barrel 4 inner chamber after setscrew nut 3, and bottom and the datum plate 8 of described class piston mechanism 6 are connected, and are connected with movable cushion block at the two ends of datum plate 8 by accurate adjustment bolt 10.
Described piston barrel 4 inner chamber top is provided with upper limit 5, and the bottom of piston barrel inner chamber is provided with lower limit 7.
The bottom of described class piston mechanism 6 is welded with datum plate 8 roof by pipe link, drives class piston mechanism 6 to move by coarse adjustment screw rod 2, and class piston mechanism 6 drives datum plate 8 to move again, adjusts roughly the height of movable cushion block 9.
Realized the fine setting of movable cushion block 9 by accurate adjustment bolt 10, make the height of movable cushion block 9 more accurate, safer during guarantee handling convection-plate, reduce dangerous.
