For realizing above-mentioned purpose, technical scheme of the present invention is following:
A kind of recipient lifting appliance comprises:
Dovetail furrow, said dovetail furrow are arranged on the recipient outer circumference surface, and said dovetail furrow bottom surface is processed with detent, and said dovetail furrow and detent are round-corner transition;
Swallow tail, said swallow tail lower end and said dovetail furrow match, and the upper end is equipped with suspension ring, is movably installed with pull bar on the said swallow tail, also is processed with the knock hole of corresponding said detent on the said swallow tail;
Locating dowel pin, said locating dowel pin slip cap is contained in the said knock hole, and said locating dowel pin is arranged with spring outward, and said locating dowel pin two ends can telescopically lean said pull bar and detent respectively.
Further, also be movably installed with two pins that prevent that said pull bar from coming off from said swallow tail on the said pull bar.
Further, said pull bar one end also is equipped with and draws handrail.
Further, said pull bar cross-sectional plane is square, and said pull bar bottom is processed with wedge-shaped part, is processed with the wedge-shaped impression that matches with said wedge-shaped part on the said locating dowel pin head end.
Further, said detent and locating dowel pin quantity are 2, and are symmetricly set on said swallow tail both sides.
Beneficial effect of the present invention is, the present invention compared with prior art, the present invention adopts cooresponding dovetail furrow and swallow tail; Cooperate reliably, suspension ring are installed on swallow tail, realize lifting easily; Whole round-corner transitions can not produce stress concentration on the dovetail furrow, can not destroy recipient integral structure function yet; Improve recipient service life, thereby objectively reduce production costs, the present invention adopts the locating dowel pin location; Make that the recipient hoisting process is safe and reliable, avoid the generation of accident in the recipient hoisting process.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further explain:
Fig. 1 looks scheme drawing for recipient master in a kind of recipient lifting appliance of the present invention;
Fig. 2 looks scheme drawing for the recipient right side in a kind of recipient lifting appliance of the present invention;
Fig. 3 is a kind of recipient lifting appliance of the present invention structural representation;
Fig. 4 be among Fig. 3 A to structural representation.
The specific embodiment
The exemplary embodiments that embodies characteristic of the present invention and advantage will be described in detail in following explanation.Be understood that the present invention can have various variations on various embodiment, its neither departing from the scope of the present invention, and explanation wherein and accompanying drawing be the usefulness of being used as explanation in itself, but not in order to restriction the present invention.
Recipient 1 structure such as Fig. 1 and shown in Figure 2 among the present invention; Be tubular structure; Be convenient this recipient 1 of lifting, processing one dovetail furrow 12 on the outer circumference surface 11 of recipient 1, this dovetail furrow 12 is a round-corner transition; To prevent on recipient 1, producing stress concentration, destroy the integral structure and the function of recipient 1.
Like Fig. 3 and shown in Figure 4,, process a swallow tail 2 that matches with these dovetail furrow 12 geomeries for cooperating the use of dovetail furrow 12 on the recipient 1.These swallow tail 2 upper ends are protuberance 21, and protuberance 21 upper end end faces are installed with suspension ring 22 through screw thread, convenient through steel rope etc. recipient 1 are lifted.
On dovetail furrow 12 bottom surfaces, also be processed with the detent 13 of two symmetries, this detent 13 also is a round-corner transition, and these detent 13 degree of depth are 8～10 millimeters.The position of this detent 13 is the protuberance 21 both sides shoulders 23 of corresponding swallow tail 2, should be processed with two knock holees 24 on the position of detent 13 23 pairs of this shoulders, and this knock hole 24 is a step through-hole.In this knock hole 24, penetrate locating dowel pin 3, sheathed spring 4 on the locating dowel pin 3, these spring 4 one ends lean locating dowel pin 3 head bottom surfaces, and the other end leans the step surface of this knock hole 24.
On swallow tail 2 top protuberances 21, be processed with along the through hole of swallow tail 2 bearing of trends, this through hole is square, in this square through hole, penetrates a square pull bar 5.Respectively be processed with two wedge-shaped parts 51 on the position of these pull bar 5 corresponding locating dowel pins 3; These wedge-shaped part 51 bottom surfaces are the inclined-plane; Lean with locating dowel pin 3, also be processed with the wedge-shaped impression that matches with this wedge-shaped part 51 on locating dowel pin 3 head end, locating dowel pin 3 was fixing reliably when handled easily used.
Pull bar 5 both sides respectively process a small through hole 52, in this small through hole 52, penetrate pin 6, and pin 6 is positioned at swallow tail 2 protuberances 21 both sides, and accident skids off the square through hole of swallow tail 2 when preventing pull bar 5 uses.In pull bar 5 one end machining screw, and conveniently be equipped with through this screw thread and draw handrail 53, with convenient operation pull bar 5.
Use of the present invention is following:
At first swallow tail 2 is penetrated dovetail furrow 12; And knock hole 24 alignd with detent 13, then with suit the locating dowel pin 3 of spring 4 penetrate in this knock hole 24, re-use and draw handrail 53 easily pull bar 5 to be penetrated in the square through hole on swallow tail 2 protuberances 21; The face that leans of alignment pull bar 5 and locating dowel pin 3; Make the wedge-shaped part 51 of pull bar 5 be stuck in the wedge-shaped impression of locating dowel pin 3 heads, and make spring 4 compressions produce restoring force, on pull bar 5, penetrate pin 6 then in the small through hole 52; At last on the suspension ring 22 of swallow tail 2 upper ends, penetrate steel rope, can lift recipient 1 easily and reliably.After lifting is accomplished; At first take off the pin 6 on the pull bar 5, through pushing locating dowel pin 3 pull bar 5 is taken out from the square through hole of the protuberance 21 of swallow tail 2 again, let go the back under spring 4 restoring force effects; Locating dowel pin 3 ejects; Take out locating dowel pin 3 and spring 4 this moment quickly and easily, extract swallow tail 2 out dovetail furrow 12 along dovetail furrow 12 bearing of trends at last, just accomplished all processes.Repeat said process when lifting once more and get final product, very convenient, reliable, quick.
Beneficial effect of the present invention is, the present invention compared with prior art, the present invention adopts cooresponding dovetail furrow 12 and swallow tail 2; Cooperate reliably, suspension ring 22 are installed on swallow tail 2, realize lifting easily; Whole round-corner transitions can not produce stress concentration on the dovetail furrow 12, can not destroy recipient 1 integral structure function yet; Improve 1 service life of recipient, thereby objectively reduce production costs, the present invention adopts locating dowel pin 3 location; Make that recipient 1 hoisting process is safe and reliable, avoid the generation of accident in recipient 1 hoisting process.
Technical scheme of the present invention is disclosed as above by preferred embodiment.Those skilled in the art should recognize change and the retouching of under the situation that does not break away from appended scope of the present invention that claim disclosed of the present invention and spirit, being done, and all belong within the protection domain of claim of the present invention.
