Abstract
The utility model provides a pneumatic tensioning device which is composed of a fixed bracket, a movable bracket, a tensioning cylinder, a track joint, a movable guide rail, a conveying chain and a fixed track. The pneumatic tensioning device is characterized in that: when equipment is in running and the conveying chain starts running after penetrating through the track joint and the movable guide rail, air flow enters the cylinder through an air inlet pipeline joint; when the air flow in the cylinder reaches certain pressure value, namely is larger than 0.2MPa and smaller than 0.4MPa, a stop valve on the cylinder is closed, the cylinder maintains certain tensioning force and then generates displacement so as to push the movable bracket to move rightwards, and the maximum displacement is 300mml when the alarm pressure value is set 0.4MPa or larger than 0.4MPa, a safety valve can be automatically opened, so as to lead the equipment to be in the alarm state or to stop running. The pneumatic tensioning device mainly has the following advantages: the initial tension value can be set at will, and small area is occupied; in addition, as a pressure alarm device is provided, the conveying and running conditions can be detected.
Description
Technical field the utility model relates to the tightening device field on the conveyer chain, and concrete is a kind of Pneumatic tension device.
The background technology tightening device mainly is to be used for conveyer chain in application and relevant industries, and tensioned and heavy bell type tightening device two big classes are arranged.These two kinds of tightening devices use wider, belong to traditional tensioning mode, and its performance cuts both ways.Heavy bell type tensioning device structure tube list, weight is generally the 1-3 piece, and the balance weight iron of the about 25kg of weight can't be realized the micro-adjustment of counterweight.And tensioned has been saved installing space with respect to the heavy bell type tightening device, but spring in use, is not very long owing to be subjected to reverse load effect, its service life for a long time, and often damages easily.
Summary of the invention is in order to overcome above-mentioned deficiency, and main purpose of the present utility model aims to provide a kind ofly can set the tension force initial value arbitrarily, it is little to take up room, be provided with pressure warning unit, and can provide to detect and carry running condition.
The technical solution adopted in the utility model is: Pneumatic tension device is made up of fixed support, traversing carriage, tensioning cylinder, rail joint, movable guiding rail, conveyer chain, trapped orbit, pulley.Rail joint is connected with the trapped orbit left end, the trapped orbit right-hand member links to each other with movable guiding rail, trapped orbit is on fixed support, traversing carriage is also on fixed support, 4 pulleys are arranged on the traversing carriage, tensioning cylinder one end is connected center, traversing carriage left side, and the other end links to each other with fixed support, and conveyer chain links to each other with rail joint.
Tensioning cylinder is made up of cylinder, safety valve, compression indicator, shutoff valve, admission line joint.
Principle of work of the present utility model is: when equipment operation, when conveyer chain passes rail joint, movable guiding rail operation, air communication is crossed the admission line joint and is entered in the cylinder, air-flow in the cylinder reaches certain force value promptly greater than 0.2Mpa during less than 0.4Mpa, shutoff valve on the cylinder is closed, and makes cylinder keep certain tensile force, produces displacement then, the promotion traversing carriage moves right, and maximum displacement is 300mm; When the alarm pressure setting value is 0.4Mpa or during greater than 0.4Mpa, safety valve will be opened automatically, make equipment be in alarm condition or arrestment operation.
The utility model mainly is useful in a kind of power tightening device on the conveyer chain of application and relevant industries.
Main advantage of the present utility model is to set the tension force initial value arbitrarily, and it is little to take up room, and is provided with pressure warning unit, can be used for detecting conveying running condition.
Description of drawings

Fig. 2 is a STRUCTURE DECOMPOSITION scheme drawing of the present utility model
Be specific embodiment of the utility model shown in specific embodiment Fig. 1,2, mainly be useful in a kind of strength tightening device on the conveyer chain of application and relevant industries, form by fixed support 1, traversing carriage 2, tensioning cylinder 3, rail joint 4, movable guiding rail 5, conveyer chain 6, trapped orbit 7, pulley 8.Rail joint 4 is connected with trapped orbit 7 left ends, trapped orbit 7 right-hand members link to each other with movable guiding rail 5, trapped orbit 7 is on fixed support 1, traversing carriage 2 is also on fixed support 1,4 pulleys 8 are arranged on the traversing carriage 2, tensioning cylinder 3 one ends are connected center, traversing carriage 2 left side, and the other end links to each other with fixed support 1, and conveyer chain 6 links to each other with rail joint 4.
Tensioning cylinder is made up of cylinder 9, safety valve 10, compression indicator 11, shutoff valve 12, admission line joint 13.
When equipment operation, when conveyer chain 6 passes rail joint 4, movable guiding rail 5 operations, air communication is crossed the admission line joint and is entered in the cylinder 9,9 air-flow reaches certain force value promptly greater than 0.2Mpa during less than 0.4Mpa in the cylinder, shutoff valve 12 on the cylinder is closed, and makes cylinder keep certain tensile force, produces displacement then, promote traversing carriage 2 and move right, maximum displacement is 300mm; When the alarm pressure setting value is 0.4Mpa or during greater than 0.4Mpa, safety valve 10 will be opened automatically, make equipment be in alarm condition or arrestment operation.
