Description

The layer-changing coiling device in the cold-setting automatic coiling equipment of the elevator balance compensation chain

technical field

The invention relates to the field of elevator balance compensation chain cold-setting automatic coiling equipment, in particular to a layer-changing coiling device in the elevator balance compensation chain cold-setting automatic coiling equipment.

Background technique

The packaged elevator balance compensation chain made of welded anchor chain, PVC and composite materials through extrusion processing has the advantages of good elasticity, high strength, long life, stable and reliable elevator operation, etc., and has a large market demand. The PVC and composite materials wrapped by the wrapped elevator balance compensation chain are thermoplastic materials. Therefore, during the extrusion process of the wrapped elevator balance compensation chain, it is necessary to press the elevator balance compensation chain in a warm state according to the extrusion speed. The first layer is from inside to outside, the second layer is from outside to inside, or the first layer is from outside to inside, and the second layer is coiled from inside to outside, and coiled layer by layer to the required height, so that the elevator balance compensation chain can be as straight as possible. It is cold-set to improve the quality of elevator balance compensation chain products. The current coiling method relies on manual work, which has problems such as high labor intensity, low production efficiency, poor occupational health and safety environment, cold setting accuracy and product quality of the compensation chain are difficult to guarantee.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a layer-changing coiling device in the elevator balance compensation chain cold-setting automatic coiling device, which can conveniently and reliably guide the compensation chain to the The upper layer is coiled to meet the requirement of coiling the compensation chain layer by layer to the required height.

The object of the present invention is achieved in this way: the layer-changing coiling device in the elevator balance compensation chain cold-setting automatic coiling device includes a walking trolley, which is connected with a driving device, and the output end of the driving device is connected with a gear. The side of the trolley is connected to the vertically arranged ball slider guide rail, and a vertically arranged rack is arranged on one side of the trolley. The two sides of the rack are co-located in the ball slider guide rail. Connect the chain guide rings to the upper and lower ends respectively.

When coiling, the compensation chain passes through the chain guide ring at the upper end and the chain guide ring at the lower end. The driving device drives the gear to rotate, and the rack moves down, so that the lower end chain guide ring is an appropriate distance from the flat trolley for coiling, and now the rack is at its lower limit position. Turn off the driving device, the rack is at its lower limit position and the traveling trolley is relatively stationary, the compensation chain is coiled on the track-shaped track from outside to inside, coiling at the bottom layer, and when the bottom layer coiling operation is completed, the drive device is reversed to make The gear drives the rack to move up the diameter of a compensation chain, keeping the distance between the lower end of the chain guide ring and the bottom compensation chain that has just been coiled as the appropriate distance required for coiling, and the compensation chain is coiled from the inside to the outside. The gear drives the rack again to move up the diameter of a compensation chain, and in this way, the compensation chain can be coiled layer by layer to the required height.

As an improvement of the present invention, each chain guide ring is rectangular in shape, and each chain guide ring includes four hollow cylindrical rollers, and a support shaft is respectively inserted in each hollow cylindrical roller, and each hollow cylindrical roller passes through two hollow cylindrical rollers respectively. The two rolling bearings are supported on the corresponding support shafts, and the ends of each support shaft are respectively connected with the ends of adjacent support shafts through connecting pieces. Because there are various diameter specifications of the elevator balance compensation chain, such a structure can be applied to compensation chains of different diameters. When the compensation chain with the largest diameter is in the square structure, its outer surface is in contact with four hollow cylindrical rollers, and when the compensation chain with the smallest diameter is in the square structure, the outer surface of its wrapping layer is in contact with two hollow cylindrical rollers. During the coiling process, when the chain lifting device continuously lifts the compensation chain and lowers it continuously along the chain guide ring, the compensation chain drives the hollow cylindrical drum to roll. Since the hollow cylindrical drum has a small mass and a rolling bearing inside, the compensation chain can The chain easily drives the drum to rotate, ensuring that the wrapping layer of the compensation chain is not damaged.

The driving device of the present invention includes an electric motor connected to the worm reducer. Because, the tilt compensation chain hanging between the driving wheel and the chain guide ring has a downward force on the rack, which will make the rack move down until the chain guide ring at the lower end lands on the coiled compensation chain. On the chain, it cannot continue to coil. The worm reducer is self-locking, and can only drive the worm gear to rotate, but not the worm gear to drive the worm to rotate, so that only the gear and the rack can move here, and the rack and the gear cannot rotate. Therefore, no matter how much the downward component force of the inclined compensation chain acts on the rack, there will be no phenomenon that the rack cannot be coiled due to the downward movement of the rack.
