Abstract
The invention discloses a stay bar with adjustable length. The stay bar comprises an outer barrel, and an inner barrel inserted into the outer barrel, wherein a plurality of locating insertion holes are oppositely formed in the inner barrel and the outer barrel; bolts penetrate into the locating insertion holes; threads are arranged on the bolts, and the bolts are screwed and fixed on the inner barrel and the outer barrel by nuts; the stay bar structure with adjustable length is formed by connection. The length of the overall stay bar can be adjusted by pushing and pulling the inner barrel of the stay bar, and the anticipated length of the stay bar is fixed by the bolts, so that the problem that the length of an existing stay bar cannot be adjusted is solved, not only can the stray bar adapt to the length requirements of different hoisted objects, but also the manufacturing costs of stay bars with different lengths are saved.
Description
Technical field
The present invention relates to lifting device, relate in particular to a kind of strut lifting by adjustable in length.
Background technology
At present, in hoisting process, between lifting steel rope and suspended object, conventionally have certain angle, this angle requires to be greater than 60 °, now, because suspended object can be subject to the horizontal component of lifting rope power, therefore, produces extruding and flexing situation.When suspended object self undercapacity is during with the horizontal component of opposing lifting rope power, conventionally adjust the angle to 90 ° of lifting rope and suspended object, thereby, change suspended object stressing conditions, the horizontal force component of elimination lifting rope.In this case, just require to increase a strut and realize this function between suspension hook and suspended object, the length of strut is two distances between suspension centre.Along with the change of suspended object contour structures, the chosen position of suspension centre also changes thereupon, and corresponding strut length is also not quite similar, often cause, in an engineering item, needing the strut of different lengths, cause strut specification many, reusable rate is low, and engineering cost increases.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and a kind of strut of adjustable in length is provided, and it can be by push-and-pull strut inner core, regulates the length of whole strut, when reaching after the length of expection, uses latch locking strut length; Solve the problem that existing strut length can not regulate; Not only can adapt to different suspended object length requirement, and, the manufacturing cost of having saved different length strut.
The object of the invention is to be realized by following technical scheme:
A strut for adjustable in length, is characterized in that: comprising: an outer cylinder body, be inserted into the inner barrel in outer cylinder body, wherein, on inner barrel, outer cylinder body relative position, be provided with several positioning jacks; In positioning jack, penetrated latch, latch is provided with screw thread, and is fixed on inner barrel and outer cylinder body with nut screwing clamping; By the above-mentioned pole structure that connects and composes an adjustable in length.
The fished pipe that described inner barrel, outer cylinder body are different tube diameters.
The end of described inner barrel is provided with blind plate.
Described inner barrel end is attached with suspension centre, and suspension centre is semicircle.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, and it can, by push-and-pull strut inner core, regulate the length of whole strut, when reaching after the length of expection, uses latch locking strut length; Solve the problem that existing strut length can not regulate; Not only can adapt to different suspended object length requirement, and, the manufacturing cost of having saved different length strut.

Detailed description of the invention
As shown in Fig. 1-Fig. 6, the present invention includes: an outer cylinder body 4, be inserted into the inner barrel 3 in outer cylinder body 4, wherein, on inner barrel 3, outer cylinder body 4 relative positions, be provided with several positioning jacks; In positioning jack, penetrated latch 5, latch 5 is provided with screw thread, and tightens and be fixed on inner barrel 3 and outer cylinder body 4 with nut 6; By the above-mentioned pole structure that connects and composes an adjustable in length.
The fished pipe that above-mentioned inner barrel 3, outer cylinder body 4 are different tube diameters;
The end of above-mentioned inner barrel 3 adopts welding manner that blind plate 1 is installed; Near inner barrel 3 ends, adopt welding manner that suspension centre 2 is installed, suspension centre 2 is semicircle.
When use, adopt following steps:
One: according to Hoisting Program, select suitable strut length, inner barrel 3, outer cylinder body 4, according to selecting length to place, then, are penetrated latch 5 in the positioning jack of inner barrel 3, outer cylinder body 4, and tighten with nut 6;
Two: two steel ropes of lifting use are connected to suspension hook by one of shackle respectively, and other end is connected by buckle on the suspension centre 2 that is positioned at inner barrel 3 ends;
Three: many steel ropes of lifting use, respectively by one of shackle, then, are connected by buckle on the suspension centre 2 at inner barrel 3 two ends, and other end is connected on suspended object;
Four: try to hang;
Five: carry out lifting operation according to Hoisting Program.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
