Abstract
The utility model discloses a balanced spring device of an explosion-proof car stop barrier gate, and aims to provide a safe balanced spring device which is simple in structure and high in reliability, and is firstly realized in China. The balanced spring device of the explosion-proof car stop barrier gate comprises a balanced spring sleeve with a base, wherein a spring (1) is arranged in the balanced spring sleeve, the spring is connected to an upper pull rod (2), the other end of the spring is connected to a lower pull rod (3), the upper pull rod passes through an upper end cover (4) of the balanced spring sleeve, the lower pull rod passes through a lower end cover (6) which is provided with a nylon case (5), and the upper pull rod is connected with a rod end joint bearing (8) through a butt nut (7). The balanced spring device of the explosion-proof car stop barrier gate disclosed by the utility model is used for balancing and assisting a mechanical transmission structure in an explosive gas environment of petrochemical industries and the like.
Description
Technical field:
The utility model relates to a kind of Anti-explosion automobile blockader banister balance spring device.
Background technology:
At present, simple for structure and stable equilibrium spring arrangement with high reliability still belongs to blank at home.In the petrochemical industry, in the handling operation equipment under the explosive gas atmosphere, region of interest needs energy storage device, and this spring type safety application of installation is particularly general, such as electric fixturess such as explosion-proof banisters.
Summary of the invention:
The purpose of this utility model provides complete, the Anti-explosion automobile blockader banister balance spring device elastically of a kind of energy storage part spring.
Above-mentioned purpose realizes by following technical scheme:
A kind of Anti-explosion automobile blockader banister balance spring device, its composition comprises: the balance spring sleeve pipe with base, described balance spring sleeve pipe is in-built spring, described spring is connected on the upper connecting rod, the described spring other end connects lower link, described upper connecting rod passes the upper end cover of balance spring sleeve pipe, and described lower link passes the bottom end cover that nylon jacket is housed, and described upper connecting rod passes through connected nut connecting rod end oscillating bearing.
Described Anti-explosion automobile blockader banister balance spring device, described balance spring sleeve pipe one end connects described upper end cover and uses nut check, the described balance spring sleeve pipe other end connects described bottom end cover and uses nut check, described bottom end cover liner nylon jacket, described nylon jacket and described bottom end cover are threaded connection fastening, and described upper end cover and described balance spring sleeve pipe are connected by screw fastening.
Described Anti-explosion automobile blockader banister balance spring device, described balance spring sleeve pipe is the aluminium alloy extrusions pipe, is threaded connection between described balance spring sleeve pipe and described upper end cover, the described bottom end cover; Described connected nut and described spherical plain bearing rod end are adjusted respectively the length of balance spring and the relative position of tie point.
Beneficial effect:
1. the utility model is with the extension spring of certain design parameters, intactly be assemblied in the enclosed cavity of aluminium-alloy pipe section bar, balance spring is when work, can be capable of expansion and contraction, satisfy functional requirement, again can be when in a single day the energy storage device balance spring rupture, do not produce and strike spark, guarantee to be applied to the use safety in 1, the 2 class explosive gas atmospheres.
2. the utility model has adopted the aluminium-alloy pipe section bar, and is the extension spring of energy storage part is complete, be installed in the closed chamber elastically.
3. in a single day fracture of the extension spring in the annular seal space of the present utility model, closed chamber can guarantee that any part of extension spring does not break away from annular seal space.
4. the utility model has utilized the friction between non-ferrous metal and the carbon steel not produce pyrophoric principle.
