Abstract

The invention relates to a tension device of a suspension chain, in particular to a tensioner for a suspension chain water detection line of two air-conditioning devices. The tensioner comprises a main support, the main support is formed by mutually welding an underframe, a vertical support body, a fixing support body and a cross beam, the middle of the cross beam is provided with a pulley mechanism, and the pulley mechanism is composed of a pulley seat, a pulley shaft, a pulley, a shaft sleeve and an elastic collar for the shaft; the lower side of the pulley mechanism is provided with a gravity mechanism, and the gravity mechanism is composed of a tray, a balancing weight, a steel wire rope, a traction gear and a telescopic rod. The tensioner for the suspension chain water detection line of the two air-conditioning devices is an auxiliary device for the suspension chain water detection line of the two air-conditioning devices, automatic distance adjusting is achieved by utilizing the weight of the balancing weight, and therefore automatic tensioning of the suspension chain is achieved; the tensioner for the suspension chain water detection line of the two air-conditioning devices is large in adjusting torque, wide in range, and very suitable for the usage of the suspension chain water detection line of the two air-conditioning devices; meanwhile, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to a tensioning device of a suspension chain, in particular to a tensioner used for the water detection line of the suspension chain of two air conditioners. Background technique [0002] The air-tightness test of the two air conditioners is usually carried out by hoisting the product through the water inspection pool through the suspension chain. The suspension chain is a mechanical transmission that uses the flexible wire tensioned on the pulley to perform motion or power transmission. The suspension chain It has the characteristics of simple structure, stable transmission, shock absorption, large shaft spacing and multi-axis transmission, low cost, no need for lubrication, easy maintenance, etc. It is widely used in modern mechanical transmission.

AI Technical Summary

Problems solved by technology

[0002] The air-tightness test of the two air conditioners is usually carried out by hoisting the product through the water inspection tank through the suspension chain. It has the characteristics of simple structure, stable transmission, cushioning and vibration absorption, power transmission between large shaft distances and multiple shafts, low cost, no need for lubrication, and easy maintenance. It is widely used in modern mechanical transmissions. However, due to The load on the shaft is large, and the suspension chain is subjected to tension for a long time, which is prone to permanent deformation, increases the length of the suspension chain, causes relaxation, and reduces the life of the suspension chain, which requires regular tensioning of the suspension chain

[0003] In the suspension chain drive, some maintenance measures are taken to keep the suspension chain working in a tensioned state. The existing technology is to add a tension wheel on the inner side of the tension wheel. Since the suspension chain is a hoisting product, the weight of the product on the suspension chain When it is enlarged, the general tensioning wheel cannot realize the deformation of large torque, which will easily cause hard damage to the suspension chain
