For achieving the above object, technical scheme of the present invention is as follows:
A kind of recipient lifting appliance, described recipient outer circumference surface is provided with dovetail furrow, and described dovetail furrow bottom surface is processed with detent, and described dovetail furrow and detent are round-corner transition; Described lifting appliance comprises:
Swallow tail, described swallow tail lower end and described dovetail furrow match, and the upper end is equipped with suspension ring, is movably installed with pull bar on the described swallow tail, also is processed with the knock hole of corresponding described detent on the described swallow tail;
Locating dowel pin, described locating dowel pin slip cap is contained in the described knock hole, and described locating dowel pin is arranged with spring outward, and described locating dowel pin two ends can telescopically lean described pull bar and detent respectively.
Further, also be movably installed with two pins that prevent that described pull bar from coming off from described swallow tail on the described pull bar.
Further, described pull bar one end also is equipped with and draws handrail.
Further, described pull bar cross-sectional plane is square, and described pull bar bottom is processed with wedge-shaped part, is processed with the wedge-shaped impression that matches with described wedge-shaped part on the described locating dowel pin head end.
Further, described detent and locating dowel pin quantity are 2, and are symmetricly set on described swallow tail both sides.
Beneficial effect of the present invention is, the present invention compared with prior art, the present invention adopts corresponding dovetail furrow and swallow tail, cooperate reliable, at swallow tail suspension ring are installed, realize lifting easily, whole round-corner transitions on the dovetail furrow, can not produce stress and concentrate, 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, makes that the recipient hoisting process is safe and reliable, avoids the generation of accident in the recipient hoisting process.

Below in conjunction with accompanying drawing the present invention is described in further detail:
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 feature of the present invention and advantage will be described in detail in the following description.Be understood that the present invention can have various variations at different embodiment, its neither departing from the scope of the present invention, and explanation wherein and accompanying drawing be when the usefulness that explain in itself, but not in order to limit 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, outer circumference surface 11 processing one dovetail furrow 12 at recipient 1, this dovetail furrow 12 is round-corner transition, to prevent that producing stress at recipient 1 concentrates, and destroys integral structure and the function of recipient 1.
As shown in Figure 3 and Figure 4, for cooperating the use of dovetail furrow 12 on the recipient 1, process a swallow tail 2 that matches with these dovetail furrow 12 geomeries.These swallow tail 2 upper ends are protuberance 21, and protuberance 21 upper end end faces are installed with suspension ring 22 by screw thread, convenient by steel rope etc. recipient 1 are lifted.
Also be processed with the detent 13 of two symmetries on dovetail furrow 12 bottom surfaces, this detent 13 also is 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, and position that should detent 13 23 pairs of this shoulders is processed with two knock holees 24, and this knock hole 24 is 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.
Be processed with along the through hole of swallow tail 2 bearing of trends at swallow tail 2 top protuberances 21, this through hole is square, penetrates a square pull bar 5 in this square through hole.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, penetrate pin 6 in this small through hole 52, 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 by this screw thread and draw handrail 53, with convenient operation to pull bar 5.
Use of the present invention is as follows:
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, last suspension ring 22 in swallow tail 2 upper ends penetrate steel rope, can lift recipient 1 easily and reliably.After lifting is finished, at first take off the pin 6 on the pull bar 5, by pressing 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 finished all processes.Repeat said process when lifting again 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 corresponding dovetail furrow 12 and swallow tail 2, cooperate reliable, at swallow tail 2 suspension ring 22 are installed, realize lifting easily, whole round-corner transitions on the dovetail furrow 12, can not produce stress and concentrate, 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, makes that recipient 1 hoisting process is safe and reliable, avoids 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 doing under the situation that does not break away from the scope and spirit of the present invention that the appended claim of the present invention discloses, all belong within the protection domain of claim of the present invention.
