Abstract
A cylinder type tensioner comprises a support, a blade mounting shaft, a pressure-reducing valve, a vapor filter, a two-position three-way valve and an air cylinder, wherein, the air cylinder is fixed on the upper side of the support; a through hole is formed on the upper side surface of the support; a piston lever of the air cylinder extends into the through hole; the lower end of the piston lever is connected with a lever sleeve; a pin shaft is arranged in the lever sleeve and passes through a waist type guide slot at one end of a connecting lever; and one end of the blade mounting shaft is connected with the side surface of the support through a bearing, extends into the support and is connected with the other end of the connecting lever through a fixed pin. The cylinder type tensioner continuously provides pressure for the blade of a cleaner by utilizing the air cylinder and the lever mechanism and can provide relatively constant tension force, thereby ensuring sufficiently compact binding of the blade and a belt. The magnitude of tension force is adjusted through the pressure-reducing valve; and once the pressure-reducing is adjusted, the tension is constant.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to the attending device of band conveyor tool, particularly a kind of air-cylinder type tensioner.
Background technology:
In the prior art, the clearing apparatus of colliery load-transfer device is made of blade and tightening device.Blade is used to strike off the foreign material on the load-transfer device, and tightening device keeps the pressure of blade to load-transfer device.Tightening device uses rubber spring, and still, the rubber creep-resistant property is poor, easily aging, and can cause environmental pollution, the tensile force decay that provides is very fast, blade and belt applying power are not enough after using a period of time, cause cleaning unclean, and the easier wearing and tearing of blade.
Summary of the invention:
The purpose of this utility model is to provide a kind of air-cylinder type tensioner, and described this air-cylinder type tensioner will solve the fast technical matters of rubber spring tightening device tensile force decay in the prior art.
This air-cylinder type tensioner of the present utility model is by support, the blade installation shaft, reducing valve, the aqueous vapor filter, two-position three-way valve and cylinder constitute, wherein, described cylinder is fixedly installed on the upside of described support, be provided with through hole in the support upper side, the piston rod of cylinder extends in the described through hole, the lower end of piston rod is connected with a bar cover, be provided with a bearing pin in the described bar cover, described bearing pin passes the interior waist type guide groove of an end of a connecting rod, one end of described blade installation shaft is connected with the side of support by bearing, this end of blade installation shaft extends in the support, the other end of described connecting rod is connected with this end of blade installation shaft by set pin, cylinder is connected with described two-position three-way valve by two pipelines, two-position three-way valve is connected with described reducing valve, and described aqueous vapor filter is connected with reducing valve.
Further, described support is made of channel-section steel.
Further, described support is provided with bolt of rear end plate.
Further, the downside of described support is connected with dowel bolt, and described dowel bolt vertically passes the interior screw of downside of support, and dowel bolt is provided with lock nut.
Working process of the present utility model is: support is connected with the load-transfer device frame by bolt of rear end plate, earlier bolt of rear end plate is unscrewed, and twists dowel bolt then, support is moved up, determine after the location-appropriate, tighten lock nut dowel bolt is locked, tighten bolt of rear end plate again with fixed support.Reducing valve is transferred to the position of less pressure, regulates two-position three-way valve, make the piston rod of cylinder be in the shortest route place, blade installation shaft and connecting rod are connected as a single entity with set pin.Slowly regulate reducing valve again, gaseous tension is increased gradually, at last reducing valve is stabilized in a certain position.The pressure of gas drives the rotation of blade installation shaft down by the effect of bar cover and connecting rod and set pin in the cylinder, thereby provides tensile force for the blade on the blade installation shaft.Because connecting rod is provided with waist type guide groove at the connecting portion that itself and bar overlap, so piston rod can move up and down.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model utilizes cylinder and leverage to continue to provide pressure to sweeper blade, and comparatively constant tensile force can be provided, and guarantees that the applying of blade and belt is enough tight.The tensile force size is regulated by reducing valve, in case after reducing valve regulated, tensile force was just invariable.
Description of drawings:
Fig. 1 is that the master of air-cylinder type tensioner of the present utility model looks scheme drawing.
Fig. 2 is that scheme drawing is looked on the left side of air-cylinder type tensioner of the present utility model.
The specific embodiment:
As depicted in figs. 1 and 2, air-cylinder type tensioner of the present utility model, by support 16, blade installation shaft 9, reducing valve 1, aqueous vapor filter 2, two-position three-way valve 3 and cylinder 4 constitute, wherein, described cylinder 4 is fixedly installed on the upside of described support 16, be provided with through hole in support 16 upper sides, the piston rod 6 of cylinder 4 extends in the described through hole, the lower end of piston rod 6 is connected with a bar cover 7, be provided with a bearing pin 13 in the described bar cover 7, described bearing pin 13 passes the interior waist type guide groove of an end of a connecting rod 8, one end of described blade installation shaft 9 is connected by the side of bearing with support 16, this end of blade installation shaft 9 extends in the support 16, and the other end of described connecting rod 8 is connected with this end of blade installation shaft 9 by set pin 10.Cylinder 4 is connected with described two-position three-way valve 3 by two pipelines, and two-position three-way valve 3 is connected with described reducing valve 1, and described aqueous vapor filter 2 is connected with reducing valve 1.
Further, described support 16 is made of channel-section steel 15.
Further, described support 16 is provided with bolt of rear end plate 5.
Further, the downside of described support 16 is connected with dowel bolt 12, and described dowel bolt vertically passes the interior screw of downside of support 16, and dowel bolt is provided with lock nut 11.
