Abstract
The present invention announces a kind of telescopic hydraulic cylinder for bearing rotation torque, belongs to Expansion belt conveyor field.Including the cylinder body being fixed on bearing, and the piston rod being connected with cylinder body；The piston rod end is fixed with bindiny mechanism；Assembly pulley is installed in the bindiny mechanism；The front and rear side of the bindiny mechanism is respectively fixed with a slide bar；The slide bar is arranged in parallel with piston rod；Side is respectively fixed with a support plate before and after the cylinder body；Through hole is provided with the support plate, the sliding bar is arranged in corresponding support plate through hole.Two slide bars of the invention are applied in combination with hydraulic cylinder piston rod, and when the object that the present invention is acted on is per se with rotation torque, hydraulic cylinder piston rod also will not together rotate with object.Further, since the blessing effect of two slide bars, hydraulic cylinder piston rod can bear larger radial load, prevent hydraulic cylinder piston rod flexural deformation, the function of being transmitted with ting model hydraulic cylinder compared with noticeable effort is realized.
Description
Technical field
The present invention relates to Expansion belt conveyor field, specifically a kind of telescopic hydraulic cylinder for bearing rotation torque.
Background technology
The important component of Telescopic is realized as shown in figure 1, hydraulic tensioning cylinder is Expansion belt conveyor, all the time,
Hydraulic tensioning cylinder is all to use common high-pressure hydraulic cylinder, and this hydraulic cylinder can bear larger tension and supporting role, and
Sealing is preferable, but can not bear rotation torque.When tension on belt, under the rotation torque effect of steel wire rope in itself, hydraulic pressure
Cylinder is easy to rotate, by wirerope-winding together, so that winch can not normally folding and unfolding steel wire rope, tightening belt.Will
Steel wire rope changes no moment of torsion steel wire rope into and is avoided that above mentioned problem, but because expensive without moment of torsion steel wire rope, colliery is now seldom
Using.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of telescopic hydraulic cylinder for bearing rotation torque.
The present invention is achieved through the following technical solutions：It is a kind of to bear the telescopic hydraulic cylinder of rotation torque, including be fixed on
Cylinder body on bearing, and the piston rod being connected with cylinder body；The piston rod end is fixed with bindiny mechanism；The connection machine
Assembly pulley is installed on structure；The front and rear side of the bindiny mechanism is respectively fixed with a slide bar；The slide bar is parallel with piston rod
Arrangement；Side is respectively fixed with a support plate before and after the cylinder body；Through hole is provided with the support plate, the sliding bar is installed
In corresponding support plate through hole.
It is further：Linear bearing is installed between the support plate through hole and slide bar.
One end that the slide bar is close to bindiny mechanism is provided with external screw thread；Slide bar, which is connected through a screw thread, is fixed on bindiny mechanism
On.
Hydraulic cylinder piston rod is linked with both sides slide bar, and relative rotation is limited between slide bar and cylinder body.When assembly pulley by
During the rotation torque of steel wire rope, in the presence of two slide bars, assembly pulley will not rotate.
Compared with prior art, the beneficial effects of the invention are as follows：Two slide bars are applied in combination with hydraulic cylinder piston rod, when this
When the object of invention effect is per se with rotation torque, hydraulic cylinder piston rod also will not together rotate with object.In addition,
Due to the blessing effect of two slide bars, hydraulic cylinder piston rod can bear larger radial load, prevent hydraulic cylinder piston rod bending
Deformation, realizes the function of being transmitted with ting model hydraulic cylinder compared with noticeable effort.

Embodiment
The following is the specific embodiment of the present invention, in conjunction with accompanying drawing, the present invention will be further described.
The telescopic hydraulic cylinder of rotation torque is born as shown in Fig. 2 a kind of, including the cylinder body b being fixed on bearing c, and
The piston rod 1 being connected with cylinder body b；The end of piston rod 1 is fixed with bindiny mechanism 2；Assembly pulley a is installed in bindiny mechanism 2.
The front and rear side of bindiny mechanism 2 is respectively fixed with a slide bar 3；One end that slide bar 3 is close to bindiny mechanism 2 is provided with outer spiral shell
Line；Slide bar 3, which is connected through a screw thread, to be fixed in bindiny mechanism 2；Slide bar 3 is arranged in parallel with piston rod 1；The side before and after cylinder body b
It is respectively fixed with a support plate 4；Through hole is provided with support plate 4, slide bar 3 is slidably mounted in the corresponding through hole of support plate 4；Support plate 4
Linear bearing 5 is installed between through hole and slide bar 3.
