Abstract
The invention discloses a blocking wheel, in particular to a hydraulic blocking wheel for being applied to rotary kiln equipment in material calcining workshops in a factory to be used for adjusting the cylinder of a rotary kiln to move along the axis direction of the rotary kiln. The hydraulic blocking wheel comprises a hydraulic oil cylinder (1), a piston (2), a piston rod (3), a blocking wheel (5) and a blocking wheel shaft (7), wherein the end part of the piston rod (3) is connected with the blocking wheel shaft (7), and an aligning block (4) is arranged in the middle of the piston rod (3); and an aligning bearing (6) is arranged on the blocking wheel shaft (7). The hydraulic blocking wheel has simple structure, is suitable for high-temperature, overload and serious-wear rotary kiln equipment, completely changes the phenomenon that the original rotary kiln rolling ring and riding wheel wears seriously and unevenly, reduces the maintenance number of the rotary kiln equipment, improve the operation rate of the rotary kiln equipment, reduces equipment maintenance cost and increases the economic benefit of the factory.
Description
Technical field
The present invention relates to a kind of gear wheel, relate in particular to be applied in and be used to adjust the hydraulic blocking wheel that cylinder of rotary kiln moves along the rotary kiln axis direction on factory's material calcining workshop rotary kiln device.
Background technology
Rotary kiln is a kind of equipment that is used for calcining materials.This equipment is owing to be operated in the condition of high temperature, when cylinder of rotary kiln in operation process, the length of cylindrical shell can produce the phenomenon of expanding with heat and contract with cold because of the change of environment temperature, is fixed on the rolling ring that is used for supporting cylinder on the cylindrical shell and produces displacement along rotary kiln axis to making.Traditional hydraulic blocking wheel is owing to be subjected to the restriction of self structure, and part comes with some shortcomings.Working face as gear wheel is difficult to accomplish to contact fully with the rolling ring working face, and piston produces bigger radial load in the oil cylinder under the effect of axial force component, pull the oil cylinder working face when piston is moved reciprocatingly in oil cylinder, make chamber, oil cylinder front and back produce the oily phenomenon of string.This will reduce or still lose the thrust of hydraulic blocking wheel.Therefore keep rolling ring to contact with the effective of support roller working face, being unlikely to make rolling ring or support roller to produce concentrated wear is the technical problem that those skilled in the art are badly in need of solving.
Summary of the invention
The present invention is exactly in order to solve the problems of the technologies described above, and a kind of hydraulic blocking wheel is provided, and purpose is to keep rolling ring to contact with the effective of support roller working face, prevents rolling ring or support roller generation concentrated wear.
In order to solve the problems of the technologies described above, the present invention is achieved in that hydraulic blocking wheel, and it is to be made of hydraulic jack, piston, piston rod, gear wheel and gear wheel axle, and wherein the end of piston rod connects the gear wheel axle, the middle part of piston rod is the aligning piece, on the gear wheel axle self-aligning bearing is installed.
Described gear wheel axle and fairlead are structure as a whole.
Described fairlead is enclosed within on the axis of guide.
Described fairlead is fixed on the bearing.
Described bearing is installed on the basis.
Described aligning piece is a cylindrical structure, and cylindrical two ends are interior concave spherical.
Described aligning piece is divided into two sections with piston rod.
Described gear wheel is installed on the gear wheel axle by self-aligning bearing, thrust bearing and spheric seating.
Described hydraulic jack is a single-acting high pressure low discharge oil cylinder.
Advantage of the present invention and effect are as follows:
Piston rod of the present invention promotes the stressing conditions that gear wheel has improved piston by the aligning piece, has prolonged the service life of piston and hydraulic jack; Adopted radial-axial aligning structure to guarantee that rolling ring contacts with the effective of support roller working face simultaneously.
Hydraulic blocking wheel of the present invention is simple in structure, is applicable on the rotary kiln device of high temperature, heavy duty, serious wear, thoroughly changed rotary kiln rolling ring in the past and support roller serious wear and wearing and tearing uneven now to.Reduce the rotary kiln device maintenance frequency, improved the running rate of rotary kiln device, reduced the maintenance of equipment cost, improved the economic benefit of factory.

The specific embodiment
Below in conjunction with attached Fig. 1 and 2 hydraulic blocking wheel 13 of the present invention is described in further detail.But protection scope of the present invention is not limit by embodiment.
As illustrated in fig. 1 and 2, hydraulic blocking wheel is the split combining structure, and it is to be made of hydraulic jack 1, piston 2, piston rod 3, gear wheel 5 and gear wheel axle 7, and wherein the end of piston rod 3 is connected with gear wheel axle 7, the middle part of piston rod 3 is an aligning piece 4, and self-aligning bearing 6 is installed on the gear wheel axle 7.Aligning piece 4 is a cylindrical structure, and cylindrical two ends are interior concave spherical, and aligning piece 4 is divided into two sections with piston rod; Aligning piece 4 has avoided piston to produce axial force.
Above-mentioned gear wheel axle 7 is structure as a whole with fairlead; Fairlead is enclosed within on the axis of guide 11; Fairlead is fixed on the bearing 10; Bearing 10 is installed on the basis.
Above-mentioned gear wheel 5 is installed on the gear wheel axle 7 by self-aligning bearing 6, thrust bearing 8 and spheric seating 9.Hydraulic jack 1 can adopt single-acting high pressure low discharge oil cylinder.
Operation principle of the present invention is as follows: hydraulic oil enters the hydraulic cylinder back cavity and promotes piston, piston rod, aligning piece, gear wheel axle, forces gear wheel to move along the axis of guide.Driving cylinder of rotary kiln by gear wheel moves axially.Finish cylindrical shell and move regulatory function, kept effective the contacting of rolling ring 12 with support roller 14 working faces along rotary kiln axis.
