Abstract
The utility model provides a saw blade lifting device for a sampling saw. The saw blade lifting device is simple in structure and convenient to operate, and can reduce the direct contact between operators and saw blades and potential safety hazard and is characterized by comprising a lifting support and a saw blade positioning block, and the saw blade positioning block is arranged on the lower part of the lifting support through a locking structure.
Description
Technical field
The utility model relates to the detection frock field of hot rolled seamless steel tube, is specially a kind of saw blade lifting appliance of the saw of taking a sample.
Background technology
It in the hot rolled seamless steel tube production process process control of strengthening quality; In time understand the pipe quality situation of grasping; Generally all behind emphasis operation place, set up the sampling saw, the steel pipe that rolls out is taken a sample, measure its external diameter, wall thickness and inspection surfaces externally and internally quality.Because saw blade belongs to consumable store and need irregularly change.The replacing of field sampling saw saw blade at present normally adopts steel wire penetrating saw blade hole for hoist 13 to lift, change, and sees Fig. 1, and its process is loaded down with trivial details, operation inconvenience, and saw blade is prone to personnel are damaged in operating process, has bigger potential safety hazard.
Summary of the invention
To the problems referred to above, the utility model provides a kind of saw blade lifting appliance of the saw of taking a sample, its simple in structure, simple operation, and can reduce the direct contact between operating personal and the saw blade, reduce potential safety hazard.
Its technical scheme is such, it is characterized in that: it comprises hoisting bracket and saw blade locating piece, and said saw blade locating piece is installed on said hoisting bracket bottom through locking mechanism.
Said locking mechanism comprises rotary handle, adapter shaft; Said adapter shaft passes the both ends that said hoisting bracket and said saw blade locating piece and said rotary handle are individually fixed in said adapter shaft through lining; Said saw blade locating piece off-centre is installed on said adapter shaft end; The axial location pin also is installed on the said rotary handle, has knock hole and locking hole on the said hoisting bracket, said axial location pin is plugged in said knock hole or the said locking hole;
Said rotary handle comprises rotating handle, handle; Said rotating handle one end is fixed with said adapter shaft, the other end is threaded with said handle; Said handle outer cover is equipped with loop bar; Said axial location bearing pin is set with spring to passing said handle and being connected through pin with said loop bar between said handle and the loop bar; Said knock hole and said locking hole are the center, are that symmetry distance is symmetricly set on the said hoisting bracket with the distance of axis to the adapter shaft axis of said handle with the axis of said adapter shaft.
Adopt the saw blade lifting appliance of the utility model sampling saw; Its beneficial effect is: it is simple in structure, easy to use; Lifting only need be plugged in the saw blade locating piece lifting eye of saw blade and get final product through the locking mechanism back lifting that is locked during saw blade, and wherein locking mechanism comprises the adapter shaft that passes hoisting bracket, and the two ends of adapter shaft are installed with lifting saw blade and rotary handle and lift by crane saw blade off-centre and are installed on the adapter shaft end; Correspondence is provided with knock hole and locking hole on axial location pin, the hoisting bracket and rotary handle is provided with; After saw blade locating piece plug-in mounting is gone into the saw blade hole for hoist, rotate rotary handle, because saw blade locating piece off-centre is installed on the end of adapter shaft, thereby the saw blade locating piece can tighten the interior week of saw blade hole for hoist; Then the axial location pin plug-in mounting of rotary handle is gone into to be about to the saw blade locking in the knock hole of hoisting bracket; Can carry out the lifting of saw blade, operating personal need not to contact the saw blade sawtooth part in whole lifting process, has effectively reduced potential safety hazard.
Description of drawings
Fig. 1 is sampling saw saw-blade structure scheme drawing;
Fig. 2 is saw blade lifting appliance structural representation under the lifting state of the utility model sampling saw.
The specific embodiment
See Fig. 2, the saw blade lifting appliance of the utility model sampling saw, it comprises hoisting bracket 1 and saw blade locating piece 2, saw blade locating piece 2 is installed on hoisting bracket 1 bottom through locking mechanism.Locking mechanism comprises rotary handle 3, adapter shaft 4; Adapter shaft 4 passes the both ends that hoisting bracket 1 and saw blade locating piece 2 and rotary handle 3 are individually fixed in adapter shaft 4 through lining 12; And saw blade locating piece 2 off-centre are installed on adapter shaft 4 ends; Axial location pin 5 also is installed on the rotary handle 3; Have knock hole 6 and locking hole 14 on the hoisting bracket 1, axial location pin 5 is plugged in knock hole 6 or the locking hole 14, and axial location pin 5 is plugged in the knock hole 6 when lifting appliance is in non-lifting state; And when saw blade locating piece 2 plug-in mountings are gone into saw blade hole for hoist 13 in when lifting appliance is in work lifting state, rotate rotary handle 3 and axial location pin 5 plug-in mountings are gone in the locking hole 14 be; Rotary handle 3 comprises rotating handle 7, handle 8; Rotating handle 7 one ends are fixed with adapter shaft 4, the other end is threaded with handle 8; Handle 8 outer cover are equipped with loop bar 9, and axial location pin 5 axially passes handle 8 and is connected through pin 10 with loop bar 9, is set with spring 10 between handle 8 and the loop bar 9; Knock hole 6 and locking hole 14 with the axis of adapter shaft 4 be the center, with axis to the adapter shaft axis of handle 8 be that symmetry distance is symmetricly set on the hoisting bracket 1 apart from d, level pulling loop bar 9 can be gone into axial location pin 5 plug-in mountings in knock hole 6 or the locking hole 14 during use.
