Abstract
The utility model discloses a supplementary hand protector device of hand -held sinker current manual rejects the unnecessary part on the work piece for overcoming, hits the hired roughneck with the light hammer and cuts a hole because of both top contact areas are little, can make shortcoming that misalignment slippage between them takes place to injure by a crashing object the staff provide because of carelessness. The mountable is at the sleeve on hand -held sinker top, including overlapping the barrel at the hand -held sinker stalk portion to and with the barrel on the concentric cylindricality round platform of being connected, the external diameter of cylindricality round platform is greater than the external diameter of barrel. Because above -mentioned sleeve can overlap at the top of hand -held sinker, the round platform area that the sleeve top was equipped with is great, can shelter from the staff of holding up the chisel of shaking hands, makes the hand of holding the handrail chisel avoid receiving the injury, the increasing of the hammering area of round platform simultaneously makes effective probability of transmission hand hammer impact power increase, has also improved work efficiency.
Description
Technical field
This utility model belongs to affiliated facility, a kind of when artificial use hand chisel rejects unnecessary material, prevents the protection device that staff is injured by hand hammer.
Background technology
The main equipment used on port and pier is various in style, and its organizational structure is the most extremely complex, and this brings many difficulties to maintenance of equipment work.In maintenance process, often occur can not being machined into the problem that equipment is repaired completely, it is necessary to complete by hand, such as, need to reject with hand hammer and hand chisel the privileged sites of some parts so that it is reach to use requirement.With when manually rejecting, the shank of a hand steered chisel of shaking hands, by the blade of the hand chisel position to rejecting to needs, another hand-held hammer carries out impact to the top of hand chisel and beats.
Owing to hand hammer and hand chisel are general utility tool, therefore will consider that the adaptability of instrument is extensive manufacturing when.Currently used hand hammer impact hand chisel top, between two instruments, the contact surface of end is the least, during beaing, do not notice that arising that hand hammer does not impact hits exactly but secundly at the top of hand chisel, because the impact in shots slips, will pound on the staff holding up chisel of shaking hands, make the hand of operator come to harm, the when of even the veteran worker doing this work for a long time also makes mistakes, work exists potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is, overcome the manual redundance rejected on workpiece of prior art, little because of both top contact area with hand hammer impact hand chisel, imprudence can make both center deviations slip the shortcoming injuring staff by a crashing object, it is provided that the auxiliary hand guard device of a kind of hand chisel.
In order to solve the problems referred to above that prior art exists, this utility model is to use following technical proposals to realize: may be installed the sleeve on hand chisel top, including the cylinder that can be enclosed within hand chisel shank, and the cylindricality round platform that be connected concentric with cylinder upper end, the external diameter of described cylindricality round platform is more than the external diameter of described cylinder.
This utility model also has a techniques below feature:
It is provided with excessive circular arc at described round platform and cylinder junction；
The described sleeve being enclosed within hand chisel top, the endoporus of its cylinder and hand chisel shank are matched in clearance, and the sidewall of cylinder is vertically provided with the penetrating screw installing fixing bolt；
Described screw is the interior hexagonal dormant bolt hole that bolt head can be made not expose drum surface；
The interior hole length of described cylinder is 2/3rds of hand chisel shank length.
During use, by the barrel jacket of described sleeve at the shank of hand chisel, by the blade of the hand chisel position to rejecting to parts, hold the cylinder periphery of sleeve, beat the cylindricality round platform top of sleeve upper end with the knocking of another hand-held hands, owing to the diameter of round platform is more than cylinder external diameter, the hands holding cylinder is blocked by round platform, even if hands knocking trains off the centre from round platform, also will not get to the hands holding up chisel of shaking hands, thus just protected the safety of operator, eliminate the hidden danger that staff in work is hurt.
Advantage of the present utility model and good effect are, owing to above-mentioned sleeve can be enclosed within the top of hand chisel, the round platform area that sleeve top is provided with is relatively big, can shelter from the staff holding up chisel of shaking hands, and make the hands holding handrail chisel avoid coming to harm；The increasing of the hammering area of round platform simultaneously, makes the Effective Probability of transmission hand hammer impulsive force increase, also improves work efficiency.
Accompanying drawing explanation
Fig. 1 is schematic front view of the present utility model；
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
In Fig. 1, may be installed the sleeve on hand chisel 4 top, including cylinder 2 and the cylindricality round platform 1 that be connected concentric with cylinder 2 top, the external diameter of described round platform 1 is more than the external diameter of described cylinder 2.
During work, cylinder 2 by above-mentioned sleeve is enclosed within the top of hand chisel 4, operator's adept hammer on the other hand, and one holds and holds up the cylinder 2 being enclosed within hand chisel 4 shank to start working.Owing to cylinder 2 is enclosed within the shank of hand chisel 4, the round platform 1 on cylinder 2 top shelters from holding the hand holding up cylinder 2, and staff is served protective effect.
During in order to prevent from impacting described cylindricality round platform 1 top with hand hammer, the coupling part of cylindricality round platform 1 and cylinder 2 produces stress and concentrates, and also makes that people is hand steered to hold when cylinder 2 works more comfortable simultaneously, is provided with excessive circular arc R in the junction of described cylindricality round platform 1 and cylinder 2.
When being enclosed within hand chisel 4 shank for the most described cylinder 2, the endoporus 2.1 making cylinder 2 obtains shank with hand chisel 4 and is connected more stable, it is matched in clearance between endoporus 2.1 and hand chisel 4 shank, simultaneously on the sidewall of cylinder 2, vertically it is provided with the penetrating screw installing fixing bolt, withstand the shank of hand chisel 4 with fixing bolt, make the stability connected each other more preferable；
Surface in order to prevent the bolt head fixing hand chisel 4 on cylinder 2 from exposing cylinder 2 is stabbed and is held the staff holding up cylinder 2, and described screw is that interior hexagonal dormant bolt hole 3(sees Fig. 2), so use hexagonal dormant bolt fixing the most firm but also cylinder 2 surface will not be exposed.
More firm in order to make to be connected between the cylinder 2 of sleeve and hand chisel 4 equally, also make cylinder 2 not touch the parts of surrounding, the length of described endoporus 2.1 is advisable with account for hand chisel 4 shank length 2/3rds.
During use, endoporus 2.1 by sleeve upper shell 2 is enclosed within the top of hand chisel 4, the shank of hand chisel 4 is held out against in being screwed into interior hexagonal dormant bolt hole 3 with hexagonal dormant bolt, hold the position of the cylinder 2 of sleeve, the top of described round platform 1 is beaten with hands knocking, diameter due to round platform 1 is more than the external diameter of cylinder 2, the hands holding cylinder 2 is blocked by round platform 1, even if hands knocking trains off the centre from round platform 1, also the hands holding up chisel 4 of shaking hands will not be got to, thus eliminating potential safety hazard, it is ensured that operator preserve from, and improve work efficiency.
