Abstract
The utility model provides a stroke switch structure of a pneumatic executing mechanism, which comprises a gas cylinder body, a guide rod and two stroke switches, wherein the guide rod is fixedly connected with a piston rod of the gas cylinder body through a synchronizing rod, baffle blocks are fixedly arranged on the guide rod, and the piston rod of the air cylinder body drives the baffle blocks to respectively knock the stroke switches when extending out and retracting back. The utility model is characterized in that the two stroke switches are arranged at one end near the gas cylinder body, the number of the baffle blocks is two, and the two baffle plates are respectively arranged at both ends of the guide rod and are respectively positioned at the outer sides of the two stroke switches. Because the two stroke switches are arranged at one end near the gas cylinder body, the cable wire connection is convenient, and in addition, the protective level of IP65 can be realized only through installing a waterproof outer cover.
Description
Technical field
The utility model relates to the automatic control technology field, is specially the travel switch structure of pneumatic actuator.
Background technique
In the automatic control component of large-scale baffle door in thermal power plant and insertion plate door, the pneumatic actuator position limit switch, realize the automatic control of large-scale baffle door and insertion plate door, existing pneumatic actuator travel switch structure as shown in Figure 1, the piston rod 5 of cylinder block drives guide rod 2 motions by synchronizing bar 6, a block 4 is arranged on this guide rod 2, two position limit switch 3-1,3-2 is installed in the two ends near pneumatic element (cylinder) 1 respectively, block 4 stretches out at piston rod 5, clash into the position limit switch 3-2 at pneumatic element (cylinder) 1 two ends during withdrawal respectively, 3-1 sends respectively and closes the door, enabling signal.Because two position limit switch 3-1,3-2 are installed in the two ends of close pneumatic element (cylinder) 1 respectively, the cable connection on position limit switch 3-1, the 3-2 will pick out from two ends respectively, and is very inconvenient.Two position limit switch 3-1,3-2 are installed separately in the open, realize that security level is IP65, install two waterproof outer cover.
Summary of the invention
At the problems referred to above, the utility model provides the travel switch structure of pneumatic actuator, is convenient to cable connection on the position limit switch, and does not need to install two waterproof outer cover.
Its technological scheme is such: a kind of travel switch structure of pneumatic actuator, it comprises cylinder block, guide rod, two position limit switches, described guide rod is fixedlyed connected with the piston rod of described cylinder block by synchronizing bar, be installed with block on the described guide rod, the piston rod of described cylinder block stretches out, drive described block during withdrawal and clash into described position limit switch respectively, it is characterized in that: described two position limit switches are installed in the end near described cylinder block, described block is two, and described two blocks are installed in the two ends of described guide rod and lay respectively at the outside of two position limit switches.
It is further characterized in that: described two position limit switches are installed in piston rod one end near described cylinder block.
Because two position limit switches are installed in a end near described cylinder block by a mounting plate, are convenient to cable connection, and will realize that security level is IP65, only need to install a waterproof outer cover.
Description of drawings
Fig. 1 is the travel switch structure figure of existing pneumatic actuator;
Fig. 2 is the travel switch structure figure of the utility model pneumatic actuator.
Embodiment
See Fig. 2, the utility model comprises cylinder 1, guide rod 2, be installed in two position limit switch 3-1 near cylinder block one end, 3-2, guide rod 2 is fixedlyed connected with the piston rod 5 of cylinder block by synchronizing bar 6, piston rod 5 withdrawals, driving guide rod 2 when stretching out is synchronized with the movement with piston rod 5, two block 4-1,4-2 is contained in the two ends of guide rod 2 respectively and is positioned at two position limit switch 3-2, the outside of 3-1, piston rod 5 stretches out, drive block 4-1 during withdrawal, 4-2 clashes into two position limit switch 3-2 respectively, 3-1, by position limit switch 3-2,3-1 provides two signals respectively, thereby has realized the automatic control of baffle door and insertion plate door.Because two position limit switch 3-2,3-1 are installed in an end of close cylinder block 1, facilitate the cable connection of position limit switch 3-2,3-1 like this, will realize that simultaneously security level is IP65, position limit switch 3-2,3-1 are installed in only need install a waterproof outer cover when open-air.
Claims (2)
1. the travel switch structure of a pneumatic actuator, it comprises cylinder block, guide rod, two position limit switches, described guide rod is fixedlyed connected with the piston rod of described cylinder block by synchronizing bar, be installed with block on the described guide rod, the piston rod of described cylinder block stretches out, drives when withdrawing described block and clashes into described position limit switch respectively, it is characterized in that: described two position limit switches are installed in the end near described cylinder block, described block is two, and described two blocks are installed in the two ends of described guide rod and lay respectively at the outside of two position limit switches.
