[0002] An elevator is a vertical transportation device, usually composed of a closed car, guide rails, motors, control systems and other components. During the installation of the elevator, a wire-releasing device is required to release the cables in an orderly manner.

[0003] A Chinese patent with announcement number CN220055829U discloses an elevator installation and wire-releasing device, comprising: a mounting frame, on which two bearings are provided; a rotating roller, installed between the two bearings; two positioning plates, detachably installed on the rotating roller, a retractable assembly of a winding area for winding or installing a winding roller with a wire rope wound thereon is formed between the two positioning plates, the retractable assembly is provided on one side of the positioning plate away from the winding area, and the movable end of the retractable assembly is arranged toward the positioning plate; the utility model places the winding roller on an auxiliary device, and the auxiliary device is used to assist in its wire-releasing.

[0004] The existing wire-releasing device for elevator installation cannot ensure the accuracy of wire-releasing when releasing the wire, which may easily lead to incorrect length, position or connection method of the cable, thereby affecting the stability of the elevator's electrical signal transmission and control system, and even causing the elevator to fail to operate normally and the elevator's electrical system to malfunction; therefore, a wire-releasing device for elevator installation is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised by the above-mentioned background technology, the utility model proposes an elevator installation wire-releasing device.

[0006] The technical solution adopted by the utility model to solve its technical problems is: an elevator installation and pay-off device described in the utility model comprises a base; a fixed frame is fixedly connected to the base, a pay-off roller is rotatably installed in the fixed frame through a rotating shaft, a motor is installed on the side wall of the fixed frame, the output end of the motor is connected to one end of the rotating shaft, a rope is wound around the pay-off roller, the lower end of the rope is fixedly connected to a casing, a movable seat is arranged in the casing, a first electrode plate is fixedly connected to the top of the movable seat, a second electrode plate is installed on the top inner wall of the casing, a first indicator light is installed on the side wall of the fixed frame, the first indicator light, the second electrode plate and the first electrode plate are electrically connected, and when When paying out the wire, the electric motor is operated to make the pay-out roller rotate, and then the rope is paid out. As the rope continues to move downward, the casing, movable seat and cable also move downward. When the movable seat moves down to the top of the car, if it continues to move downward, the casing will drive the second electrode plate to move down until it contacts the first electrode plate, and the first indicator light will be powered on and light up, so as to remind people to stop the pay-out operation in time, thereby ensuring the accuracy of the cable pay-out length, ensuring the correct connection of the elevator's electrical system, avoiding problems with incorrect length, position or connection method of cables and control lines, helping to ensure the stable transmission of the elevator's electrical signals, allowing the elevator to operate normally, and reducing problems such as elevator stops and malfunctions due to electrical failures.

[0007] Preferably, a fixed block is fixed on the base, a swing rod is hinged on the fixed block, and two auxiliary rollers are rotatably mounted on the swing rod. When the device is used, the auxiliary rollers can assist the pay-off roller in performing the rope pay-off operation.

[0008] Preferably, a fixing plate is fixedly connected to the base, a spring is fixedly connected between the fixing plate and the swing arm, a fixing column is fixedly connected to the fixing plate, a switch button is installed on the top of the fixing column, a second indicator light is installed on the side wall of the fixing frame, and the second indicator light is electrically connected to the switch button. During the line-release process, the two auxiliary rollers on the swing arm are pulled downward by the rope, so that the swing arm swings down and presses the switch button. At this time, the spring is in a compressed state and the second indicator light is in a powered-on state, indicating that the line-release length is the same as the depth of the elevator shaft, and can cooperate to achieve accurate line-release. When the line-released cable is loose, the swing arm is separated from the switch button under the action of the spring, and the second indicator light is in a powered-off state, indicating that the cable is too long and the line-release length is not standard, which affects the lifting effect of the elevator.

When the device is used, the bottom end of the cable can be fixed by the cooperation of the fixing ring and the locking bolt.

[0010] Preferably, a battery box is installed on the base, a wire is connected to the battery box, and the other end of the wire is arranged on the casing. When the device is used, a stable power supply can be provided for the elevator by arranging the battery box and the wire.

[0011] The utility model is beneficial in that:

[0012] 1. When the utility model is releasing the wire, the electric motor is operated to rotate the wire-releasing roller, and then the wire-releasing operation is performed on the rope. As the rope continues to move downward, the casing, the movable seat and the cable also move downward. When the movable seat moves downward to the top of the car, if it continues to move downward, the casing will drive the second electrode plate to move downward to contact the first electrode plate, and the first indicator light will be powered on, so that people can be reminded to stop the wire-releasing operation in time, thereby ensuring the accuracy of the cable wire-releasing length, ensuring the correct connection of the elevator's electrical system, avoiding problems such as incorrect length, position or connection method of the cable and the control line, and helping to ensure the stable transmission of the elevator's electrical signals, so that the elevator can operate normally, and reducing problems such as elevator stop and malfunction caused by electrical failures;

[0013] 2. During the wire-laying process of the utility model, the two auxiliary rollers on the swing arm are pulled downward by the rope, causing the swing arm to swing down and press the switch button. At this time, the spring is in a compressed state, and the second indicator light is energized, indicating that the wire-laying length is the same as the elevator shaft depth, and can cooperate to achieve accurate wire-laying. When the wire-laying cable is slack, the swing arm is separated from the switch button under the action of the spring, and the second indicator light is in a power-off state, indicating that the cable is too long and the wire-laying length is not standard, which affects the lifting effect of the elevator.
