Embodiment
The present invention is described in further detail with preferred embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, in conveying worm carrier chain strainer, including：Mounting bracket 1, installation axle 2
Two ends are movably arranged on mounting bracket 1 by bearing respectively, and tensioning shaft 3 is set parallel to installation axle 2, installation axle 2 and tensioning shaft 3
Between be provided with swinging mounting 4, the two ends of swinging mounting 4 are connected in installation axle 2 and tensioning shaft 3, described tensioning shaft 3
On be provided with tightener sprocket 5, tightener sprocket 5 is engaged against on carrier chain 6, the piston rod of swinging mounting 4 and single-acting cylinder 7
It is connected, single-acting cylinder 7 is widely used in mechanical field, and the side of the cylinder body inner carrier of single-acting cylinder 7 is gas chamber, living
Fill in and compression spring is installed on the piston rod in the cylinder body of opposite side, compressed gas enters after gas chamber, in gas chamber
Gas pressure in the presence of, piston is moved to compression spring side, so that piston rod is stretched out and compression spring, straight
To piston both sides stress balance.Described single-acting cylinder 7 is arranged on the mounting bracket 1 of the top of swinging mounting 4, single-acting cylinder
It is connected between 7 and source of the gas by air inlet pipe 8, magnetic valve 9 is provided with described air inlet pipe 8, between source of the gas and magnetic valve 9
The pressure-reducing valve 10 of gas pressure size can be adjusted by being provided with air inlet pipe 8.In the present embodiment, magnetic valve 9 and pressure-reducing valve 10 it
Between air inlet pipe 8 on be provided with pressure detection switch 11, when pressure detection switch 11 detects pressure in air inlet pipe 8 less than setting
During definite value, pressure detection switch 11 can send this signal to the controller in conveying worm, so that controller is sent out
Go out halt instruction.The piston rod of single-acting cylinder 7, which extends downwards, can drive swinging mounting 4 to drive tensioning shaft 3 downward around installation axle 2
Rotate, thus drive the tightener sprocket 5 on tensioning shaft 3 to move downward and so that carrier chain 6 is tensioned.In the present embodiment, tensioning shaft 3
It is provided with the mounting bracket 1 of top on proximity switch 12, the piston rod of single-acting cylinder 7 and sensing support 13 is installed, sensing branch
The upper-end part of driving of frame 13 is in the detection range of proximity switch 12, and when carrier chain 6 is broken, the piston rod of single-acting cylinder 7 then can
Elongation downwards is to range, so that the upper end for driving sensing support 13 to move downwardly to sensing support 13 departs from proximity switch
12 detection range, proximity switch 12 will send this signal to the controller in conveying worm, so that controller
Send halt instruction.
Operation principle is as follows：During work, the valve opening of magnetic valve 9 causes the compressed air with setting pressure in source of the gas to pass through decompression
Valve 10 is entered in the cylinder body of single-acting cylinder 7 from air inlet pipe 8, the single-acting cylinder 7 in the presence of gas pressure in cylinder body
Piston rod extends downwards, drives swinging mounting 4 to drive tensioning shaft 3 to be rotated down around installation axle 2, so as to drive on tensioning shaft 3
Tightener sprocket 5 move downward and cause carrier chain 6 be in tensioning state, now the piston in the cylinder body of single-acting cylinder 7 be in by
Dynamic balance state.In the conveying worm course of work, once carrier chain 6 loosens, the gas in the cylinder body of single-acting cylinder 7
In the presence of pressure, piston can be at once to the side movement of compression spring, until the piston rod of single-acting cylinder 7 drives tensioning chain
Wheel 5 is moved downwardly to so that the continuation holding tensioning state of carrier chain 6, so ensures that the whole work process in conveying worm
In, carrier chain remains at tensioning state, so as to substantially increase the conveying stability and transfer efficiency of conveying worm；This
The tensioning mode of carrier chain 6 is also very convenient, and tensioning regulation can be carried out automatically.Subtract because the compressed air of source of the gas can be first passed through
Pressure valve 10, pressure-reducing valve 10 can be adjusted to entering the gas pressure size in single-acting cylinder 7, so as to carrier chain
The size of 6 tensile forces is controlled, and can thus be prevented effectively from causes carrier chain 6 to be broken or because of tensioning because tensile force is excessive
The situation generation that power is too small and causes carrier chain 6 to loosen.In the conveying worm course of work, it is broken once occurring carrier chain 6
Failure when, in the cylinder body of single-acting cylinder 7 in the presence of gas pressure, the piston rod of single-acting cylinder 7 can extend downwards to
Range, so that dynamic answers support 13 to move downwardly to the upper end of sensing support 13 and the detection range of proximity switch 12
It is separated, the controller that now detection switch 12 will be transmitted the signal in conveying worm makes controller send shutdown
Instruction, so that conveying worm is stopped, thus effectively prevent the conveying worm when carrier chain 6 is broken and continues
Run and cause the accident of equipment or cargo damage to occur.Cause the gas pressure in air inlet pipe 8 small when source of the gas breaks down
When setting value, pressure detection switch 11 can send this signal to the controller in conveying worm, so that control
Device sends halt instruction, conveying worm is stopped.The effect of pressure detection switch 11 is set to be：Avoid in gas circuit event
Under barrier state, the conveying worm operation under the loosening state of carrier chain 6 is avoided, so as to be prevented effectively from because of carrier chain loosening
The generation of the conveying worm operation troubles caused.
