Description

Technical Field

[0001] The utility model relates to the technical field of safety inspection and maintenance of stackers, in particular to a safety device for an operating platform of an electric control cabinet of a stacker. Background Art

[0002] In material management, stackers are one of the commonly used equipment. At present, when debugging the stacker's electrical control cabinet operating platform, the debugging personnel need to climb the fence on the side of the stacker's electrical control cabinet operating platform with one hand to perform debugging operations. However, during the debugging process, if other personnel accidentally start the stacker, there is a safety risk that the debugging personnel will fall from the fence. The current protective measure is to simply add a guardrail door to the fence, but according to people's movement habits, when entering the narrow debugging space enclosed by the fence, they generally do not close the guardrail door, so there is still a large safety hazard.

[0029] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0030] Please refer to Figures 1 to 4As shown, the utility model is a safety device for the stacker electric control cabinet operating platform, comprising a pedal 1 and a safety fence 2; the pedal 1 is fixedly arranged at the side bottom of the stacker electric control cabinet operating platform 4; the safety fence 2 is arranged on the pedal 1, and the safety fence 2 comprises a retaining wall 21, a guardrail door 22 and a safety door lock 23; the guardrail door 22 is opened and closed on the retaining wall 21, and the retaining wall 21, the guardrail door 22, the pedal 1 and the side of the stacker electric control cabinet operating platform 4 are enclosed to form a debugging space, and the safety door lock 23 is used to control the opening and closing of the guardrail door 22 on the retaining wall 21, and the safety door lock 23 is communicatively connected with the stacker electric control cabinet operating platform 4; when the safety door lock 23 releases the guardrail door 22, the stacker electric control cabinet operating platform 4 controls the stacker to stop running; when the safety door lock 23 constrains the guardrail door 22, the stacker electric control cabinet operating platform 4 controls the normal operation of the stacker. A pedal 1 and a safety fence 2 are added to the side of the stacker electric control cabinet operating platform 4, so that the debugging personnel can stand on the side of the stacker electric control cabinet operating platform 4 through the pedal 1. At the same time, if the debugging personnel accidentally fall from the safety fence 2, the pedal 1 can catch the debugging personnel. During the debugging process, the debugging personnel release the guardrail door 22 through the safety door lock 23, so that they can enter the debugging space to perform debugging operations, and the safety door lock 23 can control the stacker electric control cabinet operating platform 4 to control the stacker to stop running when the guardrail door 22 is released, thereby preventing other personnel from accidentally starting the stacker and causing the debugging personnel to fall out of the debugging space from the guardrail door 22.

[0031] In one embodiment, see Figure 2 and Figure 3As shown, the safety door lock 23 includes a lock shell 231, a latch 232, a door catch 233 and a micro switch 234; the lock shell 231 is arranged on the guardrail door 22, the latch 232 is slidably arranged on the lock shell 231, one end of the latch 232 is a lock tongue, the door catch 233 and the micro switch 234 are both arranged on the retaining wall 21, and the micro switch 234 is connected to the stacker electric control cabinet operation platform 4 in communication; when the lock tongue passes through the door catch 233 and contacts the trigger end of the micro switch 234, the stacker electric control cabinet operation platform 4 controls the stacker to operate normally; when the lock tongue does not pass through the door catch 233, the stacker electric control cabinet operation platform 4 controls the stacker to stop operating. The debugging personnel operate the latch 232 to move on the lock shell 231 to realize the release and restraint of the guardrail door 22 by the safety door lock 23. Specifically, when the debugging personnel pass the lock tongue of the latch 232 through the door buckle 233 and contact the trigger end of the micro switch 234, the micro switch 234 will transmit the information that the latch 232 is locked in place to the stacker's electrical control cabinet operating platform 4, so that the stacker is allowed to be started; when the debugging personnel withdraw the latch 232 from the door buckle 233, the micro switch 234 will transmit the information that the guardrail door 22 is in a free state to the stacker's electrical control cabinet operating platform 4, and the stacker is not allowed to be started.

[0032] In an optional implementation, please refer to Figure 2 and Figure 3 As shown, the lock shell 231 has an unlocking position 2311 and a locking position 2312, and the end of the latch 232 away from the lock tongue is the operating end; when the operating end of the latch 232 is located at the locking position 2312 of the lock shell 231, the lock tongue of the latch 232 passes through the door buckle 233 and contacts the trigger end of the micro switch 234, the stacker electric control cabinet operating platform 4 controls the stacker to operate normally; when the operating end of the latch 232 is located at the unlocking position 2311 of the lock shell 231, the lock tongue of the latch 232 does not pass through the door buckle 233, and the stacker electric control cabinet operating platform 4 controls the stacker to stop operating. An unlocking station 2311 and a locking station 2312 are added to the lock housing 231 to ensure that the debugging personnel can accurately control the moving position of the latch 232 in the lock housing 231 to avoid the situation where the latch 232 passes through the door buckle 233 but the lock tongue of the latch 232 does not contact the trigger end of the micro switch 234.

[0033] In an optional implementation, please refer to Figure 2 and Figure 3As shown, the lock housing 231 is provided with a guide plate 2313, the latch pin 232 can pass through the guide plate 2313, and the latch pin 232 is provided with a limit clamping spring 2321, and the limit clamping spring 2321 can abut against the guide plate 2313. The guide plate 2313 can be used to facilitate the movement of the latch pin 232, and the limit clamping spring 2321 can be used to limit the movement stroke of the latch pin 232 to prevent the latch pin 232 from overtravel.

[0034] In one embodiment, see Figure 1 As shown, the retaining wall 21 includes a plurality of upright posts 211 vertically arranged on the pedal 1 and a plurality of cross beams 212 connected between two upright posts 211. The retaining wall 21 is composed of the upright posts 211 and the cross beams 212, which is not only convenient for production and manufacturing, but also convenient for commissioning personnel to climb on the retaining wall 21, thereby eliminating the need to set up a ladder in the commissioning space.

[0035] In one embodiment, see Figure 1 As shown, a top maintenance platform 3 is provided on the top of the safety fence 2, and a through hole 31 connected to the debugging space is provided on the maintenance platform 3. The debugging personnel can climb onto the maintenance platform 3 through the through hole 31 to perform debugging operations.

[0036] In one embodiment, see Figure 1 As shown, a guardrail 32 is provided along the edge of the maintenance platform 3. The provision of the guardrail 32 can ensure the safe operation of the commissioning personnel on the maintenance platform 3.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
