Abstract
Description
Technical Field
[0001] The utility model relates to a mechanical capacity indicator of a gas cabinet which can prevent a steel wire rope of the indicator from slipping off, and belongs to the technical field of safety equipment of gas cabinets. Background Art
[0002] Gasholders are important peak-shaving equipment in gas transmission networks. In steel mills, the generation and consumption of gas often occur alternately, so that throughout the entire production process of the steel mill, there will be obvious peaks and troughs in gas usage. However, even under relatively good production conditions, the output of gas is relatively uneven relative to time. In order to effectively reconcile the contradiction between gas output and consumption, ensure that the gas pressure in the gas pipeline network does not fluctuate greatly, thereby improving the effect of gas combustion and the quality of products, further reduce gas emissions, avoid gas emissions from polluting the environment and wasting energy, and achieve dynamic balance of gas and efficient and full utilization of energy, it is necessary to use gasholders to balance the supply and demand of gas. In order to safely store as much gas as possible in the gasholder when gas is abundant and discharge as much gas as possible during the peak period of gas usage, it is necessary to use a mechanical cabinet capacity indicator to determine whether the cabinet capacity of the gasholder is within a safe range, so as to ensure the long-term stable and safe operation of the gasholder.
[0003] The existing mechanical cabinet capacity indicator converts the real-time position of the piston in the gas tank into the cabinet capacity and displays it on the mechanical cabinet capacity indicator dial through mechanical transmission mechanisms such as wire ropes, pulleys, and gears. The length of the wire rope used is as long as hundreds of meters. It was found during use that the existing mechanical cabinet capacity indicator has the problem of the wire rope slipping out of the pulley groove, causing the mechanical cabinet capacity indicator to malfunction. That is, when the gas tank is in a medium or high cabinet capacity, the piston rises to a high position, and the wire rope connected above the piston is relatively loose. The wire rope outside the gas tank cabinet will swing to a certain extent under the influence of extreme windy weather. The wire rope is easy to slip out of the pulley groove, or even get stuck in the gap between the pulley and the pulley bracket, causing the mechanical cabinet capacity indicator to malfunction. Therefore, it is very necessary to improve the existing mechanical cabinet capacity indicator. Utility Model Content

The indicator can reduce the swing amplitude of the wire rope outside the cabinet, avoid the wire rope from slipping out of the pulley groove, and enhance the operating stability of the mechanical cabinet capacity indicator in extremely windy weather.
[0005] The technical solution to solve the above technical problems is:
[0006] A gas tank capacity indicator capable of preventing a steel wire rope from slipping off comprises a steel wire rope, a guide pulley, a limit pulley, a fixing frame, a gear box and an indicator dial.

The improvement of the connection is that an anti-slip pulley and a pulley bracket are added, the anti-slip pulley and the limiting pulley are in the same plane, the anti-slip pulley and the limiting pulley are separated on both sides of the wire rope, the anti-slip pulley and the limiting pulley are staggered up and down, the pulley groove of the anti-slip pulley matches and is opposite to the pulley groove of the limiting pulley, the wire rope is respectively embedded in the relative pulley grooves of the anti-slip pulley and the limiting pulley, the wire rope is in sliding fit with the anti-slip pulley and the limiting pulley, the pulley shaft of the anti-slip pulley is connected to the front end of the pulley bracket, and the rear end of the pulley bracket is fixedly connected to the upper part of the gear box.
[0007] The above-mentioned gas tank capacity indicator that can prevent the wire rope from slipping also has a guide ring and a fixing rod. The guide ring is a circular ring, the inner diameter of the guide ring is larger than the outer diameter of the wire rope, the guide ring is sleeved on the middle part of the wire rope, and the guide ring is fixed to the outer wall of the gas tank between the guide pulley and the limit pulley on the top of the gas tank cabinet through the fixing rod.
[0008] The beneficial effects of the utility model are:
[0009] The limiting pulley and the anti-slip pulley of the utility model are respectively located on both sides of the steel wire rope, and the pulley groove of the anti-slip pulley and the pulley groove of the limiting pulley relatively clamp the steel wire rope, which can effectively reduce the radial activity space of the steel wire rope and prevent the steel wire rope from slipping out of the pulley groove of the limiting pulley when swinging; the guide ring between the guide pulley and the limiting pulley is sleeved on the outer circumference of the steel wire rope, which can limit the swing of the steel wire rope and play a synergistic role in preventing the steel wire rope from slipping.

It can reduce the swing amplitude of the wire rope and prevent the wire rope from escaping from the pulley groove of the limiting pulley, enhance the operating stability of the mechanical cabinet capacity indicator in extremely windy weather, and improve the operating safety of the gas holder in storing gas during the low gas consumption period and discharging gas during the peak gas consumption period, effectively reduce the occurrence of gas holder safety accidents, and create a good premise for efficient use of gas.
