However, if the chain breaks during the cleaning process, the lifting platform can slip off and injure workers who clean under the lifting platform, and therefore the personal safety of the workers is seriously threatened.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's is not enough, provides a safe and reliable's safety arrangement of double-deck laminator elevating platform.
The problem is solved through following technical scheme: a safety protection device for a lifting platform of a double-layer laminating machine comprises a bracket, a horizontal plate, a vertical plate, a round rod and a limit switch; the horizontal plate is fixed on the bracket, the horizontal plate is provided with a vertical hole, and the size of the vertical hole is matched with the diameter of the round rod; the vertical plate is fixedly connected with the horizontal plate, a horizontal hole towards the inside of the bracket is formed in the vertical plate, and the size of the horizontal hole is matched with that of the round rod; the limit switch is arranged below the horizontal plate, and when the round rod is inserted into the vertical hole, the round rod presses the limit switch downwards to enable the switch to be communicated; when the round rod is pulled out of the vertical hole, the switch is disconnected. According to the safety protection device for the lifting platform of the double-layer laminating machine, the horizontal plates, the vertical plates and the round rods are respectively arranged on the left side and the right side of the support. Above-mentioned safety arrangement for double-deck laminator elevating platform, the round bar comprises pole cap, pole lid and pole body, and the pole cap is fixed on the pole lid, and the pole lid is fixed on the pole body, prevents that the round bar from landing from the round hole that the cooperation set up.
The utility model has the advantages that through the cooperation of the horizontal plate, the vertical plate, the round rod and the limit switch, when the equipment needs to be cleaned, the safety protection effect can be realized, the lifting platform is prevented from rising to a high place, and when workers enter the lower part of the lifting platform for cleaning, the condition that the lifting platform slides down due to the breakage of the chain and injures the workers is avoided; the utility model discloses the security performance of machine falls two layers of promotion that can be very big has that simple structure, security are good, reliable and stable characteristics.

The list of labels in the figure is: 1. the device comprises a support, a lifting table 2, a rotating shaft 3, a horizontal plate 4, a vertical plate 5, a round bar 6, a chain 7, a motor 8 and a limit switch 9.
Detailed Description
As shown in fig. 1, 2, 3 and 4, the double-layer laminator lifting table of the safety protection device for a double-layer laminator lifting table includes a support 1, a lifting table 2, a rotating shaft 3, a chain 7 and a motor 8. Two sides of the lifting platform 2 are respectively connected with a rotating shaft 3 through shafts, a gear on the rotating shaft 3 is rotatably connected with a chain 7, the chain 7 is upwards connected with a motor 8, and the motor 8 is fixed above the bracket 1; thus, the motor 8 drives the chain 7 to drive the lifting platform 2 to lift. The safety protection device comprises a horizontal plate 4, a vertical plate 5, a round rod 6 and a limit switch 9. The horizontal plate 4 is fixedly connected with the support 1, the horizontal plate 4 is provided with a vertical hole which is communicated up and down, and the size of the vertical hole is matched with the diameter of the round rod 6. The vertical plate 5 is fixedly connected with the horizontal plate 4, the vertical plate 5 is provided with a horizontal through hole, and the size of the horizontal hole is matched with the diameter of the round rod 6; and when the round bar 6 is inserted into the horizontal hole, the length of the round bar 6 is enough to block the lifting of the lifting platform 2. The limit switch 9 is arranged below the horizontal plate 4, and when the round rod 6 is inserted into the vertical hole in the horizontal plate 4, the round rod 6 presses the limit switch 9 down to enable the switch to be switched on; when the round rod 6 is pulled out from the vertical hole on the horizontal plate 4, the round rod 6 does not contact the limit switch 9, and the switch is rebounded to cut off the power. The other side of the bracket 1 is also provided with a horizontal plate 4, a vertical plate 5 and a round bar 6, and the connection mode is the same as that of the bracket. This a safety arrangement for double-deck laminator elevating platform's use does: when the ground below the lifting platform of the double-layer laminating machine needs to be cleaned, after the lifting platform 2 reaches a high position, a worker closes a main switch of the double-layer laminating machine and pulls out the round rod 6 in the vertical hole of the horizontal plate 4 on the bracket 1; can close limit switch 9 like this, prevent that the workman from not closing the master switch of double-deck laminator, play the guard action. Then inserting the pulled round rod 6 into a horizontal hole of the vertical plate 5, wherein the round rod 6 extends inwards to the lower part of the lifting platform 2, so that the falling of the lifting platform 2 can be blocked; therefore, the lifting platform 2 caused by the breakage of the chain 7 can be prevented from sliding off, and the safety of cleaning personnel is guaranteed. After the worker finishes cleaning under the lifting platform 2, the round rod 6 in the horizontal hole of the vertical plate 5 is pulled out and inserted into the vertical hole of the horizontal plate 4, and the round rod 6 presses the limit switch 9 downwards to enable the round rod to be communicated with a circuit; the worker can carry out the laminating work by opening the main switch of the double-layer laminating machine. The horizontal plate 4, vertical plate 5 and round bar 6 on the other side of the rack 1 operate in the same manner as described above, except that there is no limit switch 9 to control. Safety protection platforms are arranged on the left side and the right side of the support 1, so that safety performance can be improved better, and safety of workers is guaranteed.
