Description

Technical Field

[0001] This utility model belongs to the field of rope pulling devices, and specifically relates to a safety rope pulling device. Background Technology

[0002] A safety rope device is a protective device that uses a mechanical rope to achieve a safety interlock. It is mainly used in industrial equipment to ensure operational safety and prevent accidents caused by misoperation or failure of the safety protection device to close.

[0003] Existing devices may expose personnel to dangerous areas such as mold opening and closing and high-temperature molten material if the operator does not fully close the safety door, leading to safety accidents such as pinching and burns. Some injection molding machines have slow response speeds in their safety protection devices, and when the operator accidentally opens the safety door during operation, the equipment may not be able to be stopped in time, leading to the escalation of the accident. Utility Model Content

[0004] To overcome the problem that existing devices may expose personnel to dangerous areas such as mold opening and closing and high-temperature molten material due to operators not fully closing the safety door, leading to safety accidents such as pinching and burns, and that some injection molding machine safety protection devices have slow response speeds, which may not be able to stop the equipment in time when the operator accidentally opens the safety door during operation, thus causing the accident to escalate, a safety pull rope device is proposed.

[0005] The technical solution of this utility model is as follows: a safety pull rope device, including a fixing mechanism; a connecting mechanism is provided at one end of the fixing mechanism, and a sensing mechanism is provided at one end of the connecting mechanism; the fixing mechanism includes a first fixing block, a first limiting block, a second limiting block, a U-shaped hole, a threaded rod, a connecting rod, a second fixing block, and a first groove; a first limiting block is fixedly connected to the upper end of one side of the first fixing block, a second limiting block is fixedly connected to the lower end of one side of the first fixing block, a U-shaped hole is opened through the upper end of the first limiting block, a threaded rod is slidably installed on the inner wall of the U-shaped hole, a connecting rod is fixedly connected to the lower end of the threaded rod, a second fixing block is slidably installed on the side wall of the connecting rod, a first groove is opened through the upper end of the second fixing block, and the side wall of the connecting rod is slidably installed on the inner wall of the first groove.

[0006] Furthermore, the connecting mechanism includes a first screw hole, a second screw hole, a third screw hole, a first screw, a first nut, and a second nut; the upper end of the first limiting block has two first screw holes, which are respectively located on both sides of the U-shaped hole; the upper end of the second fixing block has two second screw holes, and the upper end of the second limiting block has two third screw holes; the inner wall of the first screw hole is threaded with a first screw, and the first screw needs to pass through the first screw hole of the first limiting block, the second screw hole of the second fixing block, and the third screw hole of the second limiting block in sequence; the upper end of the threaded rod is threaded with a first nut, and the lower end of the threaded rod is threaded with a second nut.

[0007] Furthermore, the sensing mechanism includes a fourth screw hole, a second screw, and a bearing; a fourth screw hole is provided on one side of the second fixing block, a second screw is threaded onto the inner wall of the fourth screw hole, and a bearing is slidably installed on the side wall of the second screw.

[0008] Furthermore, the first screw hole and the second screw hole correspond one-to-one, and the second screw hole and the third screw hole correspond one-to-one.

[0009] Furthermore, a washer is provided between the lower end of the first nut and the upper end of the first limiting block; a washer is provided between the upper end of the second nut and the lower end of the first limiting block.

[0010] Furthermore, the material of the second fixing block is carbon steel plate.

[0011] Furthermore, threaded holes are provided at the four ends of one side of the first fixing block.

[0012] The beneficial effects of this utility model are:

[0013] 1. Install the bearing on the second fixing block, then fix the sensing rope to the side wall of the connecting rod. Install one end of the pull rope to a specific position on the second fixing block, and fix the other end to the mechanical safety gate of the injection molding machine. The device is now installed. Finally, use bolts to install the device onto the sheet metal of the plastic machine through the threaded holes at the four ends of the first fixing block.

[0014] 2. Operation: When the safety door of the injection molding machine is closed, the boat-shaped stopper on the safety door will strike the bearing. After the bearing is struck, it will drive the second fixed block to move downwards. The other end of the pull rope will drive the gate knife to move upwards. The guide rod will be unblocked by the gate knife, and the injection molding machine can operate. If the safety door is open, without the pressure of the stopper, the bearing will drive the second fixed block to return to its original position. The other end of the pull rope will cause the gate knife to fall and block the guide rod, preventing the guide rod from moving and the injection molding machine from operating. This solves the problem that traditional injection molding machines may cause accidents such as pinching and burns if the operator does not fully close the safety door, resulting in personnel being exposed to dangerous areas such as mold opening and closing and high-temperature molten material. Some injection molding machines have slow response speeds in their safety protection devices, and when the operator accidentally opens the safety door during operation, it may not be able to stop the equipment in time, leading to the escalation of the accident.

The guide rod will be freed from the gate knife, and the injection molding machine can operate. If the safety door is open, without the pressure of the stopper, the bearing 33 will drive the second fixed block 17 to reset upward. The other end of the pull rope will cause the gate knife to fall and jam the guide rod, preventing the guide rod from moving and the injection molding machine from operating.

The device is then installed. Finally, use bolts to install the device onto the sheet metal of the plastic machine through the threaded holes at the four ends of the first fixing block 11.

[0032] Operation: When the safety door of the injection molding machine is closed, the boat-shaped stopper on the safety door will strike the bearing 33. After the bearing 33 is struck, it will drive the second fixed block 17 to move downward. The other end of the pull rope will drive the gate knife to move upward.
