Abstract
The utility model provides a monitoring protection device is torn to belt conveyor sticky tape, has solved the not enough that prior art can not in time discover when taking place the sticky tape and tear. It is characterized in that the tightly hanging roller 2 is connected with a secondary control electric appliance device for starting limit and operating limit. The sudden change signal when the sticky tape tears can be responded and caught in time, fast to send out the parking signal, prevent accident and loss and continue to enlarge, in order to reduce the loss. The device can be used for monitoring and protecting the tearing of the rubber belt of the belt conveyor.
Description
The utility model relates to a kind of monitoring and protecting device, and particularly a kind of conveyor belt running is torn the monitoring and protecting device.
Belt conveyer of the prior art its objective is material is carried, transfers to another ground from a ground.Its structure is to be the flat idler of flute profile carrying roller on it being connected with on the steelframe, and adhesive tape places the surface of flute profile carrying roller.In adhesive tape 1 bottom surface a pair of changed course cylinder 3 is set, by this upper surface, its two ends is set hangs tight cylinder 2 by what bracing frame supported to cylinder 3 formed calixconcavity adhesive tape places, adhesive tape cycle rotation under the drive of motor, reach move, the purpose of feeding.Its weak point be in operational process often because of foreign matter, or faults itself generation adhesive tape is torn.Owing to can not in time find, stop, and cause adhesive tape to tear enlarged areas, even whole piece is scrapped.The parking replacement cycle is long, and economic loss is big.
The purpose of this utility model is to solve above-mentioned weak point of the prior art, and provides a kind of conveyor belt running to tear the monitoring and protecting device.
Technical solution of the present utility model is: make normal operating belt conveyer can in time respond to and capture the signal of this sudden change fast when tearing, send stop signal simultaneously, prevention accident and loss enlarge.It is characterized in that starting secondary control apparatus device spacing and that operation is spacing hanging tight to be connected with on the cylinder 2.
Fig. 1 looks scheme drawing for integral structure master of the present utility model.
Fig. 2 is for starting spacing and the spacing secondary control apparatus device circuit figure of operation.
The advantage that the utility model has compared to existing technology is: can be in time, rapidly Induction also captures the jump signal of normal operating ribbon conveyer when adhesive tape is torn, Send simultaneously stop sign, prevention accident and loss continue to enlarge, to reduce human, financial, and material resources The loss of power.
The utility model provides embodiment below in conjunction with accompanying drawing: belt conveyer hangs tight cylinder in startup, dependence in service and gives adhesive tape with the required tensile force of normal operation, when the generation adhesive tape is torn, the approximate adhesive tape that the travels at the uniform speed speed change of being obstructed moment, hang tight cylinder and therefore can be subjected to displacement variation, can capture rapidly and accurately in view of the above and tear signal.According to No Load Start, heavy load starting, no-load run, heavy service determine to start spacing and operation is spacing.In secondary control apparatus device circuit figure shown in Figure 3, k
2For moving spacing self-return switch, k
3Be starting limig switch.Crawl k during startup
1, make z
1k
3Be communicated with, the belt conveyer operation, spacing to be higher than operation spacing because of starting, and the operation limit switch can disconnect.When belt conveyer normally moved, the operation limit switch was closed under action of the spring, z
1Disconnect under time relay control, the operation limit switch is in running order.When adhesive tape taking place tearing, hang tight that to move to operation on the cylinder spacing, the operation limit switch disconnects, and system is out of service.Adhesive tape takes place during startup tear, hang tight to move on the cylinder and start spacingly, starting limig switch disconnects, and system is out of service.Secondary control apparatus circuit is other circuit also, if having start spacing and operation spacing.This is that the general engineering technology personnel all can realize.Be available for conveyor belt running and tear monitoring and protecting.
Claims (1)
1, a kind of conveyor belt running is torn the monitoring and protecting device; form by secondary control apparatus device; be connected with on the steelframe and be the flat idler of flute profile carrying roller on it; adhesive tape (1) places the upper surface of flute profile carrying roller; in the bottom surface of adhesive tape (1) a pair of changed course cylinder (3) is set; by this upper surface to the formed calixconcavity adhesive tape of cylinder (3) place; one its two ends is set hangs tight cylinder (2), it is characterized in that hanging tight being connected with on the cylinder (2) and start secondary control apparatus device spacing and that operation is spacing by what bracing frame supported.
