Abstract
The invention discloses a method for detecting and maintaining a braking torque value of an inertia brake of a portal crane. The method comprises the following steps: (2) firstly improving a traditional digital-display torque wrench; (2) then establishing a detection-maintenance standard for the braking torque value of the inertia brake, namely respectively selecting each inertia brake in the portal crane, verifying actual braking torque of the inertia brake by utilizing a large-scale traction device, after repeatedly adjusting the braking torque of the inertia brake and keeping the braking torque in a braking critical state, measuring the braking torque value of the inertia brake at the moment by utilizing the improved digital-display torque wrench, and verifying whether the inertia brake can reliably brake by utilizing the large-scale traction device, wherein the braking torque value of the inertia brake is taken as a detection-maintenance standard value if the inertia brake can reliably brake; and (3) comparing detection data of the braking torque value of each inertia brake with the corresponding standard value in daily detection and maintenance, and adjusting according to situations. By utilizing the method, the normal maintenance workload of the inertia brake is reduced.
Description
Technical field
The present invention relates to the detection service procedure of a kind of machine coarst brake lock torque value.
Background technology
Coarst brake is pure mechanical brake device, and braking is reliable, and fault is few.As one braking and windproof safety device, current coarst brake has been widely used in the traveling gear of the industry large lifting equipment such as harbour and metallurgy.But the size of coarst brake lock torque depends on the predetermincd tension (namely the compression degree of retarding spring) of spring, and large lifting equipment is because reasons such as deadweight skewness weighing apparatuses, lock torque required between traveling gear is not identical yet, lock torque adjusts the excessive or too small brake safe that all can not meet scene and requires: 1) lock torque adjustment is excessive, there will be drg not open, brake bush inordinate wear, or impact comparatively large when walking starting, stopping, affecting the service life of metal construction; 2) lock torque adjustment is too small, and drg cannot play braking or windbreak function.Simultaneously because coarst brake lock torque value does not quantize, if the unified its length value only provided according to manufacturer in maintenance is safeguarded, maintenance effects can vary with each individual and there is larger difference.
In order to verify the validity of coarst brake work, generally draw large lifting equipment by external large-scale draw gear (as large-duty loader or tractor truck etc.) at present, whether rolled by checking large lifting equipment road wheel and verify the validity of coarst brake lock torque value, the tractor equipment that pull test not only needs, instrument, work accessory and personnel are more, test step is relatively loaded down with trivial details, and quantities is comparatively large, the duration longer (test an equipment and at least need more than 6 hours).Simultaneously because condition is limited, can only accomplish to detect once every year, can not ensure that the long-term of drg is with effective in real time.
Therefore, the detection service procedure that a kind of coarst brake lock torque value solved the problems of the technologies described above is provided is necessary.
Summary of the invention
A technical matters to be solved by this invention is: provide a kind of and convenient, efficient detection can safeguard the method for coarst brake lock torque value.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the detection service procedure of a kind of machine coarst brake lock torque value, its concrete steps are: A). traditional Digital Electronic Torque Wrench is improved, traditional Wrench head connector is modified into by opening shape stair-stepping cylindrical, B). set up coarst brake lock torque value and detect maintenance criterion, method is: 1. choose each coarst brake in a machine respectively, 2. verify with the actual braking force square of large-scale tractor equipment to this coarst brake, by repeatedly adjusting the lock torque of coarst brake and guaranteeing that it is in the critical conditions of braking, 3. the lock torque value of now coarst brake is measured by the Digital Electronic Torque Wrench after improvement, concrete method of measurement is: inserted by the cylindrical head connector of the Digital Electronic Torque Wrench after improvement in any one manual unlocking hole of drive coupling and measure, 4. verify whether this coarst brake can reliably brake by large-scale tractor equipment again, if effective brake, then get the detection maintenance criterion value that this value is this coarst brake lock torque value, and set up the detection maintenance criterion value of every platform coarst brake lock torque value in this approach, C). during routine testing is safeguarded, the Digital Electronic Torque Wrench after direct improvement detects the lock torque value of every platform coarst brake, and detection data is compared with corresponding standard value, optionally carries out adjustment and maintenance.
As the preferred technical scheme of one, the large-scale tractor equipment in step B is large-duty loader.
Beneficial effect of the present invention: by adopting the detection service procedure in the present invention, uses the Digital Electronic Torque Wrench improved to carry out detecting and safeguarding, achieves the quantification of the lock torque value of coarst brake; Not only reduce the detection maintenance workload of coarst brake lock torque value simultaneously, make usual detection handling labor more convenient, the more important thing is the reliability and controllability that ensure that coarst brake deceleration and stopping performance, improve the safety performance of equipment.
