Abstract

Provided is a ruler matched with a two-stage elastic connection structure. A push rod penetrates through a center hole of a coupling, a nut is in threaded connection with the push rod, a spring is sleeved on the push rod, one end of the spring is elastically connected with a step of the coupling, and the other end of the spring is elastically connected with the nut. One end of the ruler is welded with the coupling or fixedly connected with the coupling through a screw and is axially parallel with the push rod. An adjustment position scale and spring pressure value scales are arranged on the ruler. A brake and the working braking force can be adjusted conveniently and accurately by using the ruler for reference.

Description

A kind of scale matching with twin-stage elastic connection structure
Affiliated technical field
The present invention relates to a kind of device of measuring spring compression degree, especially a kind of scale matching with twin-stage elastic connection structure double-stage hydraulic pusher.
Background technique
At present, known hydraulic driver is nearly all fixedly connected with the linkage structure of brake bracket, and is nearly all single-stage hydraulic pusher.This structure is not suitable for energy-saving break, is not also suitable for the stopping brake of outdoor crane.
Summary of the invention
In order to make hoist have reliable stopping brake and suitable service braking, double-stage hydraulic pusher adopts twin-stage elastic connection structure with being connected of brake bracket, the invention provides a kind of scale matching with twin-stage elastic connection structure, this scale not only can show that spring, to brake bracket applied pressure, can also indicate accurate location when break is regulated accurately.
The technical solution adopted for the present invention to solve the technical problems is: push rod is through the center hole of shaft coupling, nut is threaded with push rod, spring housing is on push rod, one end is connected with the step elasticity of shaft coupling, the other end is connected with nut elasticity, the welding of one end of scale and shaft coupling or screw is fixedly connected with and with push rod parallel to an axis, on scale, have adjusted position scale and spring pressure value scale.During regulating brake, when aliging with adjusted position scale, adjusted position reference standard represents that break has regulated; While regulating duty power, change nut location, make corresponding spring pressure value regulate reference position and required spring pressure value scale aligned in position, expression duty power has regulated.
The invention has the beneficial effects as follows, twin-stage elastic connection structure is applicable to twin-stage type break, and scale makes the adjusting of break have accurate location, and the adjusting of spring pressure size has had reference standard.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is longitudinal section of the present invention tectonic maps.
Fig. 2 is scale and scale key plan.
Fig. 3 is another kind of scale and scale key plan.
1. nuts in figure, 2. scale, 3. screw, 4. shaft coupling, 5. spring, 6. push rod, 7. adjusted position reference standard, 8. spring pressure value adjusting reference position, 9. adjusted position scale, 10. spring pressure value scale.
Embodiment
In Fig. 1, push rod (6) is through the center hole of shaft coupling (4), nut (1) is threaded with push rod (6), spring (5) is enclosed within on push rod (6), one end is connected with the step elasticity of shaft coupling (4), the other end is connected with nut (1) elasticity, the welding of one end of scale (2) and shaft coupling (4) or screw (3) is fixedly connected with and with push rod (6) parallel to an axis, on scale (2), have adjusted position scale (9) and spring pressure value scale (10).During regulating brake, when adjusted position reference standard (7) aligns with adjusted position scale (9), represent that break has regulated, in the present embodiment, adjusted position reference standard is the top plane of push rod (6); While regulating duty power, change nut (1) position, make corresponding spring pressure value regulate reference position (8) and required spring pressure value scale (10) aligned in position, represent that duty power has regulated, it is the lower plane of nut (1) that the present embodiment medi-spring force value regulates reference position (8).
In Fig. 2, scale (2) top planes is adjusted position scale (9), mutually neat with the top plane of push rod (6) as adjusted position reference standard, the upper and spring-compressed starting point of scale (2) has the spring pressure value scale (8) of many horizontal line forms to the corresponding position between spring-compressed final position.
In Fig. 3, adjusted position scale (7) is the graduation line of a horizontal line form on scale (2).

Claims (3)
