Weak current College】 【escalators and automatic sidewalk acceptance inspection.

<br> <br> First, an overview <br> Escalators and passenger conveyors relining after completion of the installation, before it is put into use, after install the unit test, by using special equipment to the requirements of the Organization, supervision, .inspection agencies and acceptance testing, experience your inspection and to special equipment safety inspection qualified flag could be put into use. <br> Pending acceptance inspection of escalators and passenger conveyors can be in the running state. <br> Second, the escalators and passenger .conveyors should provide acceptance inspection information <br> 1. manufacturing unit should provide information on: <br> A, type test certificate (copy); <br> B, the General layout plan; <br> C, installation, use and maintenance .manual; <br> D, electrical schematics and wiring diagrams and schematic diagram of the safety switch. <br> 2. install the unit should provide information on: <br> A construction records and, to post reports; <br> B, .the installation process accident records and processing reports; <br> C, the installation process by using the unit, the manufacturing units agreed to change the design of the supporting documents. <br> 3. modification (overhaul) unit should provide information on: .<br> A, above 1 and 2 two requirements; <br> B, transformation (overhaul) portion of the checklist; <br> C, main part of conformity and the type test report; <br> D, the transformation part adapted .units for the approval and signature of the drawings and calculation data. <br> III. acceptance project <br> 1. static checking <br> (1) comb plate and end-station guide device adjustments are appropriate; <br> (2 .) check whether the appropriate brake installation and adjustment; <br> (3) secondary actuator is supplied. <br> 2. dynamic test <br> (1) measuring no-load and load-time down movement of the braking distance; < .br> (2) the manufacturer shall provide the secondary brake type test certificate, specify the test date and the identification number certificate. And with the field test; <br> (3) manufacturing factory of speeding device type test certificate is valid, the .specified test date and the identification number certificate. And field test. <br> 3. driving motor current test <br> Should indicate drive motor, motor rated power of numbers, and the test voltage, record without load the upper and lower running- .current. <br> Instructions for overload protection type (three phase and single-phase current Repeater, overload or other type). Power network and the host is provided separately. <br> 4. install clearance check <br> (1) adjacent .steps (or time) clearance should not exceed 6mm. <br> (2) steps, step or tape and apron clearance should be not more than 4 mm; <br> (3) steps, step or tape and apron at both sides of .the gap total should not exceed 7mm; <br> (4) comb plate roots and cascade the distance between the treads shall be not more than 4 mm; <br> (5) handrail tape in hand steering-portal and the distance between the .floor should be not less than 0.1m, but not greater than 0.25m; <br> 5. Earth insulation resistance <br> Power circuit and safety circuit for measuring respectively. <br> 6. grounding <br> (1) all of .the metal casings are used closed wire grounding; <br> (2) maximum continuous grounding conductor resistance should be less than 0.5 Ω. <br> 7. half an hour of running <br> Escalators or moving walkway respectively the uplink and downlink 15min .15min, observation is running and whether the anomaly after run. <br> 8. electrical safety protection device <br> Check whether the following device settings, and whether the actions are correct: <br> (1) emergency stop switches; <br .> (2) traction chain broken chain protection device; <br> (3) transmission chain (or v-belt) break protection device; <br> (4) handrail tape entry protection device; <br> (5) not reverse protection .device; <br> (6) comb plate protection switch; <br> (7) working brake; <br> (8) overspeed protection switch; <br> (9) cascade collapse protection device; <br> (10) skirt .switches; <br> (11) handrail tape breakage protection device; <br> (12) auxiliary brake; <br> (13) phase sequence protectors. <br> 9. other <br> (1) check provides the following devices .: <br> (A) passengers / diagram; <br> (B) cross-protection ceiling; <br> (C) adjacent to the escalator handrail of rigid security guards; <br> (D) to enter the engine room door .in the notes. <br> (2) entrance area with a 1997 of 5 GB16899 · 2 · 1 requirements. <br> (3) escalator steps or travellators pedal or adhesive tape over the vertical NET height should not be less than 2.3m .. <br> <br> <br> <br> <br> <br>.
