Description

Technical Field

[0001] The utility model relates to the technical field of personnel protection in steel production, in particular to a roller table personnel protection system. Background Art

[0002] The 3.5-meter wire rolling mill is a continuous production site. Occasionally, equipment abnormalities occur during the production process, requiring personnel to go on the roller table to handle them. Although regulations require personnel to perform power outages and energy cuts, there are still certain deviations in the actual implementation, resulting in the equipment not being powered off and energy cuts off when personnel go on the roller table, which can easily cause accidents. Utility Model Content

[0003] In order to solve the above problems in the prior art, the utility model provides a roller conveyor personnel protection system, including a protection door, a guardrail, a control unit, a proximity sensor and a door bolt, and the protection door can be opened or closed relative to the guardrail.

[0004] The door bolt includes a bolt post, a handle and a bolt sleeve. The bolt post is slidably and rotatably connected to the protective door, the handle is fixed on the bolt post, and the bolt sleeve is fixed on the guardrail, so that when the protective door is closed, the bolt post can be inserted into the bolt sleeve when sliding. The proximity sensor is arranged on the guardrail at a position corresponding to the bolt sleeve, and is used to sense whether there is a bolt post in the bolt sleeve. The proximity sensor is connected to the control unit. When the proximity sensor does not sense the bolt post, that is, the protective door may not be closed, the control unit will cut off the power supply to the roller to prevent accidents.

[0005] Furthermore, the door bolt also includes a lock buckle, which is fixed on the protective door. The handle is also provided with a buckle hole for inserting the lock buckle to prevent the bolt from accidentally opening due to vibration and other factors, causing the roller table to stop by mistake.

[0006] Furthermore, it also includes a safety lock, wherein a lock hole is provided on the lock buckle, and the safety lock is used to pass through the lock hole when the lock buckle is passed through the lock buckle, so as to further prevent the bolt from being accidentally opened, causing the roller conveyor to stop by mistake, and also prevent the staff from accidentally opening the protective door.

[0007] Furthermore, a wireless module and a monitoring module are provided in the safety lock. The monitoring module is used to monitor whether the safety lock is locked. The wireless module is connected to the control unit to transmit the monitoring data of the monitoring module. The control unit starts the roller conveyor only when the safety lock is locked, further preventing accidents.

[0008] Furthermore, a warning light is included, which is installed on the guardrail to indicate the running status of the roller conveyor, and the warning light is connected to and controlled by the control unit. When the roller conveyor is running, the warning light reminds the staff not to enter, and when the roller conveyor is stopped, the warning light reminds the staff to enter.

[0009] When the protective door of the utility model is opened, the roller conveyor stops running, which can effectively prevent the staff from entering when the roller conveyor is running. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1 , 2 As shown, the protection system of this embodiment includes a protection door 1, a guardrail 2, a control unit, a proximity sensor 3 and a bolt 4. The protection door 1 can be opened or closed relative to the guardrail 2.

[0016] The bolt 4 includes a bolt post 5, a handle 6 and a bolt sleeve 7. The bolt post 5 is slidably and rotatably connected to the protective door 1, the handle 6 is fixed to the bolt post 5, and the bolt sleeve 7 is fixed to the guardrail 2, so that when the protective door 1 is closed, the bolt post 5 can be inserted into the bolt sleeve 7 when sliding. The proximity sensor 3 is arranged on the guardrail 2 at a position corresponding to the bolt sleeve 7, and is used to sense whether there is a bolt post 5 in the bolt sleeve 7. The proximity sensor 3 is connected to the control unit.

[0017] When the proximity sensor 3 senses the bolt 5, it means that the protective door 1 has been closed and the bolt 5 is inserted in the bolt sleeve 7, and the roller can be opened normally. When the proximity sensor 3 does not sense the bolt 5, that is, the protective door 1 may not be closed, the control unit will cut off the power supply of the roller to prevent accidents.

[0018] The bolt 4 of this embodiment also includes a lock catch 8, which is fixed on the protective door 1. The handle 6 is also provided with a lock hole 9 for passing the lock catch 8 to prevent the bolt column 5 from accidentally opening due to vibration and other factors, causing the roller table to stop by mistake.

[0019] Furthermore, a safety lock may be included. The lock buckle 8 is provided with a lock hole 10. The safety lock is used to pass through the lock hole 10 when the lock hole 9 passes through the lock buckle 8, further preventing the bolt column 5 from being accidentally opened, causing the roller conveyor to stop by mistake, and also preventing the staff from accidentally opening the protective door 1.

[0020] Preferably, a wireless module and a monitoring module are provided in the safety lock, the monitoring module is used to monitor whether the safety lock is locked, and the wireless module is connected to the control unit to transmit the monitoring data of the monitoring module. The safety lock can effectively prevent the staff from opening the protective door 1 privately, and the control unit will only start the roller conveyor when the safety lock is locked, further preventing accidents.

[0021] This embodiment further includes a warning light 11, which is installed on the guardrail 2 and is used to indicate the running state of the roller conveyor. The warning light 11 is connected to and controlled by the control unit. When the roller conveyor is running, the warning light 11 lights up red to remind the staff not to enter. When the roller conveyor stops, the warning light 11 lights up green to remind the staff to enter.

[0022] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
