Exertion and maintenance of the hoist–two
September 5th, 2008Exertion and maintenance of the hoist–two
2.3 Special apparatus accident emergency measure and rescuing the prediction scheme
According to the 31st provision that ” the special apparatus controls the regulations safely “, the applying unit of the special apparatus should make the accident emergency measure of the special apparatus and rescue the prediction scheme. Applying unit should set up and take the lead the special apparatus with the unit leader, the security administrative department of the special apparatus is a main fact, rescue the leading group, define the duty in urgent accident that relevant departments cooperate, responsibility reaches people. According to the special apparatus operating position of our unit, judge the dangerous situations of the trouble, initiation that may appear, emergence of contingency, make the counter-measure suitable for hoisting machinery of our unit. This measure should include the treatment principle after presenting the accident to the hoist tool instrument, duty, division of labor and coordination of work of procedure, method, step and relevant departments personnel taken,etc. under emergency, organize the on-the-spot manoeuvre regularly.
3 hoist tool instrument operation and management
3.1 The attenbant’s management
Attenbant want to hoist structure of tool instrument used when being on duty, learn to master in relevant knowledge and national relevant regulations, norm, standard such as operation principle, technical feature, security operational procedure, maintenance system. Train and make two respects of theory knowledge and actual operative skill to examine through the local technological superintendent office, after being qualified, it is operated that can be on duty.
3.2 The hoisting machinery one “ Three is fixed ” Manage
‘three fixations’ Management is designated man, making machine, system of determining a post. The hoisting machinery one “ Three is fixed ” The system is formulation of the system and determination of the system form at first, among them it is the foundation to make people, making machine. Require everybody have hillock have responsibility, hoist platform platform someone operate management: ” determine a post “ Responsibility is guaranteeing.
3.3 Check maintenance management regularly
The applying unit of the hoisting machinery should check and link protecting to the operating hoist tool instrument frequently, make one and check management system, including daily check, examines in week, examining, annual check of moon regularly, to that the hoist monitors dynamically, unusual situation finds, deal with in time at any time, thus ensure the safe operation of the hoisting machinery.
( 1) Daily check.
Take charge of the routine of the homework by driver and maintain the project, the main content is the sanitation and hygiene, lubricate the transmission position, adjust and fasten the work. Test the sensitive dependability of the safety device through operating, monitor and have unusual sounds while operating.
( 2) Examine in week.
Gone on together by maintenance man and driver, besides daily check project, the main content is the visual examination, sensitivity, dependability of security state, brake, clutch, urgent warning device of checking clivers, fetching the thing device, steel wire rope etc. and using, whether have unusual noises, and overheated phenomenon through operating and observing the part of the transmission.
( 3) Examine in the moon.
Organized by security administrative department of the apparatus the inspection, with using the relevant personnel of the department to go on together, besides content of examining of week, mainly to hoist dynamical system, get up, rise organization, go back, transform, construct, run mechanism, hydraulic system carry on state measure of tool instrument, change wearing and tearing, crackle, spare part corroded out of shape, to the electric control system, check whether feed device, controller, overload protection, security protector are reliable. Operate and check the trouble sign that reasons such as letting out, pressure, temperature, vibration, noise of the hoisting machinery,etc. cause through testing. Measure subjectively by observing and carrying on the state to the structure, supporting, transmission position of the hoist, understand and grasp the technological state of complete machine of the hoist, check the trouble source that confirms the unusual phenomenon.
( 4) Annual check.
Organized by unit leader in the security administrative department of the apparatus and chosen the head, go on with the related departments together, besides project of examining in the moon, mainly carry on the technical parameter to measure to the hoist tool instrument, dependability test, through detecting instrument, to hoist tool instrument, every job organization sport wearing and tearing, welding seam, test, detect a flaw of metal structure of part, through the test of safety device and part, operate the technological state and appraise to the apparatus of jack-up. Arrange to overhaul, transform, upgrade the plan.
4 hoists safe practices check the content
There are two kinds of hoisting machinery methods of inspection of safe practice, one is checked by sense organ; Another kind utilizes the tester, instrument to observe and control the apparatus.
