Abstract

The utility model relates to a safety protection net device of a belt transportation system, which comprises a plurality of protection nets arranged beside a belt, a pull rope, a chute, a slide block and a proximity switch, wherein the pull rope, the chute, the slide block and the proximity switch are sequentially connected with the protection nets; the sliding block is connected to the end part of the pull rope, and the signal end of the proximity switch is connected to a control loop of a belt conveying system; when the pull rope is pulled, the sliding block slides in the sliding groove and triggers a signal of the proximity switch, so that the control loop controls the belt to stop. This safety protection net device is through setting up the protecting wire net by the belt to adopt the stay cord to concatenate the protecting wire net together, set up the response subassembly at the stay cord end, when the protecting wire net was dismantled or when removing, the stay cord is pulled thereupon, triggers the sensing signal, makes belt conveyor system's control circuit open circuit, thereby realizes that control belt conveyor system shuts down, ensures safety.

Description

Safety protection net device of belt transportation system

Technical Field

The utility model relates to a belt conveyor system, concretely relates to belt conveyor system's safety protection network device.

Background

Belt transportation is an important transportation mode of iron and steel enterprises, and in order to ensure continuous production, workers are required to perform point inspection and maintenance on the belts. When the belt is checked by the spot check personnel, the station is close to the belt, and the safety cannot be guaranteed, so that the safety of the operating personnel is guaranteed by the protection device.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a belt conveyor system's safety protection network device, the device can ensure the security of personnel's operation.

The technical scheme is as follows: the utility model relates to a safety protection net device of a belt transportation system, which comprises a plurality of protection nets arranged beside a belt, a pull rope, a chute, a slide block and a proximity switch, wherein the pull rope, the chute, the slide block and the proximity switch are sequentially connected with the protection nets; the sliding block is connected to the end part of the pull rope, and the signal end of the proximity switch is connected to a control loop of a belt conveying system; when the pull rope is pulled, the sliding block slides in the sliding groove and triggers a signal of the proximity switch, so that the control loop controls the belt to stop.

Has the advantages that: this safety protection net device is through setting up the protecting wire net by the belt to adopt the stay cord to concatenate the protecting wire net together, set up the response subassembly at the stay cord end, when the protecting wire net was dismantled or when removing, the stay cord is pulled thereupon, triggers the sensing signal, makes belt conveyor system's control circuit open circuit, thereby realizes that control belt conveyor system shuts down, ensures safety.

fig. 2 is a schematic top view of the safety net device of fig. 1 along direction a;

fig. 3 is a partially enlarged structural view of a region B in fig. 2.

Detailed Description

As shown in fig. 1 to 3, a safety protection net device of a belt transportation system includes a plurality of protection nets 1 disposed beside a belt 100, a pull rope 2 sequentially connected in series with each protection net 1, a pulley 3 mounted on a bracket 31, a chute 6 vertically disposed beside the pulley, a slider 4 disposed in the chute 6, and a proximity switch 5 mounted on a side surface of the chute 6 and engaged with the slider 4.

The protection nets 1 include side protection nets provided on both sides of the belt 100 and end protection nets provided at ends of the belt. The pull rope 2 is arranged on the outer side of the protective net 1, so that a worker can directly pull the pull rope 2 to stop the belt 100 in an emergency. Stay cord 2 is connected with the adoption of tip protecting wire net is fixed, then transversely extends to the side protecting wire net of both sides, and the lateral surface of side protecting wire net is provided with a plurality of links 7, and stay cord 2 wears to establish in each link 7 to can guarantee that each protecting wire net 1 can stimulate stay cord 2 when being dismantled or removing, can increase the degree of difficulty that stay cord 2 was artificially pulled down at will again, guarantee safety.

Pulley 3 and support 31 are close to the tip setting of stay cord 2, and the purpose is through the cooperation of pulley 3 with stay cord 2, makes the extending direction of stay cord 2 change vertical extension into, avoids leading to slider 4 to remove too sensitively because of the horizontal extension, and light stay cord 2 shake all probably causes final equipment shut down phenomenon. The slider 4 is connected at the tip of stay cord 2, and proximity switch 5's mounting height is higher than slider 4 a little, and when stay cord 2 pulling slider 4, slider 4 slided along spout 6 upwards, triggers proximity switch 5's signal.

The signal end of the proximity switch 5 is connected to a control loop 101 of the belt conveying system, when the protective net 1 is moved or disassembled, the pull rope 2 is pulled, the sliding block 4 slides in the sliding groove 6 and triggers the signal of the proximity switch 5, and the control loop 101 controls the belt 100 to stop.

Meanwhile, the signal end of the proximity switch 5 is also connected with an acousto-optic alarm circuit, and when the signal of the proximity switch 5 is triggered, the acousto-optic alarm circuit is switched on to send out an alarm.

Be connected with safety lock 8 between tip protecting wire net and the side protecting wire net, when dismantling protecting wire net 1 usually, need open safety lock 8 earlier to increase a safety procedure, further ensure safety.
