Description

Technical Field

[0001] The utility model relates to a dry type gas cabinet leveling device, in particular to a guide pulley structure for the dry type gas cabinet leveling device. Background Art

[0002] A dry gas holder is a container device used to store various industrial gases and also to balance the unevenness of gas demand. The entry and exit of gas is achieved by the up and down movement of the piston and the baffle. In order to avoid the imbalance of the piston and the baffle during the up and down movement, a leveling device is installed on the dry gas holder. The leveling device usually includes a guide pulley and a counterweight. However, on the market, the guide pulley installed on the top of the gas holder will rust due to long-term wind and rain. Therefore, the guide pulley needs to be regularly maintained and updated, and regular replacement of the guide pulley takes a lot of time and cost. Utility Model Content

[0003] In order to solve the problems in the related art, the present application provides a guide pulley structure for a dry gas tank leveling device, which solves the problem of consuming a lot of time and cost in replacing the guide pulley.

The pulley body is characterized in that the pulley body is a nylon pulley body.

[0006] Through the above technical solution, by setting the pulley body to a nylon pulley body, the weight of the pulley body can be reduced, thereby making the pulley body more convenient to install and repair; and the pulley body made of nylon can ensure its integrity after long-term use, avoiding damage due to corrosion, and thus there is no need to replace the pulley body, thereby reducing the investment of time and cost;

[0007] Because the nylon pulley body will not generate sparks during operation, when the gas in the gas cabinet leaks to the top of the cabinet, the pulley body will not generate an ignition source due to the movement and friction of the wire rope, thereby ensuring the safety of the gas cabinet and the normal use of the gas cabinet;

[0008] Because the pulley body made of nylon has strong wear resistance and toughness, the pulley body can not only meet the wear requirements of the steel wire rope on the pulley body, but also protect the steel wire rope on the pulley body, thereby extending the service life of the leveling device on the gas cabinet;

[0009] The pulley body made of nylon material can ensure that the pulley body is noiseless during operation, thereby reducing the noise pollution of the gas cabinet during use, thereby improving the problem of noise nuisance to residents.

[0010] Preferably, the width of the bottom of the slide groove is smaller than the width of the top, so that the slide groove is arranged in a frustum shape.

[0011] Preferably, the bottom of the slide groove is arranged in an arc shape, and the center of the arc is located in the slide groove.

[0012] Preferably, first annular grooves are symmetrically arranged at both ends along the axial direction of the pulley body, and the inner diameter of the first annular groove is larger than the diameter of the rotating shaft; second annular grooves are symmetrically arranged at both ends along the axial direction of the pulley body, and the second annular groove is connected to the outer periphery of the first annular groove, and the inner groove bottom of the second annular groove is arranged in an arc shape, and the arc is arranged to protrude toward the outer side of the pulley body.

[0013] Preferably, a plurality of notches and a plurality of reinforcing ribs are respectively provided at both ends along the axial direction of the pulley body, and the plurality of notches and the plurality of reinforcing ribs provided on the same side of the pulley body are respectively arranged in sequence along the circumference of the pulley body, and each of the reinforcing ribs is provided between two of the notches, and the length direction of each of the reinforcing ribs is consistent with the diameter direction of the pulley body; the structure of each of the notches is consistent, each of the notches is arranged in a trapezoidal shape, and the length of one end of each of the notches close to the slide groove is greater than the length of one end of the notch away from the slide groove.

[0014] In summary, the beneficial effect of a guide pulley structure for a dry gas tank leveling device is that by setting the pulley body to a nylon pulley body, the weight of the pulley body can be reduced, thereby making the installation and maintenance of the pulley body more convenient; and the pulley body made of nylon can ensure its integrity after long-term use, avoiding damage due to corrosion, and thus there is no need to replace the pulley body, thereby reducing the investment in time and cost; because the pulley body made of nylon does not generate sparks during operation, when the gas in the gas tank leaks to the top of the cabinet, there is no An ignition source will be generated due to the movement and friction of the wire rope, thereby ensuring the safety of the gas cabinet and thus ensuring the normal use of the gas cabinet; because the pulley body made of nylon material has strong wear resistance and toughness, the pulley body can not only meet the need for wear of the wire rope on the pulley body, but also protect the wire rope on the pulley body, thereby extending the service life of the leveling device on the gas cabinet; the pulley body made of nylon material can ensure that the pulley body has no noise during operation, thereby reducing the noise pollution of the gas cabinet when in use, thereby improving the problem of noise nuisance.
