Electric china powered trolley land deal with the shipping company, not only save a lot of manpower and material resources, financial resources, also reduced the risk coefficient, improves the yield power, and bring more economic benefits.

 

According to the common rail electric china powered trolley, the operation principle of electric china powered trolley tracks device request is different from general device, the request of electric china powered trolley insulation between each path, must have resistance.

 

Technical features:

(1) for the insulation of the electric china powered trolley track at the request of the project to immerse to bolt to choose sulfur insulation treatment, and adding insulating elastic plate under track linking piece, usefully increase the insulation resistance between the trajectory.

(2) because of its trajectory between environmental complexity, rust and usually form meters and instruments measured resistance value is not real resistance, the project in practice, summarizes the resistance test with electric welding machine to test.

Technical process and key operation: first in the reserved hole equipment foundation and loose concrete and rock surrounding the electric china powered trolley away clean, and then the debris within the reserved hole finishing clean, finally with a small blower to clean the holes.If the reserved holes have reinforced leakage, should be dealt with in a timely manner, to ensure that the steel bar could not touch with embedded bolts.Electric china powered trolley bolt device

(1) bolt insulation treatment: in order to ensure that after the bolt under water wet insulation, bolts should be choose sulfur soaking treatment, namely first after being the sulfur melting, will bolt thread following some choose sulfur immerses, comes out to dry.

(2) the detailed method of bolt device:

(1) anchor bolt clean grease, rust must be removed.

(2) after the bolts into, should correct its top level orientation and height, and fixed.

(3) grouting material mixing water should introduce water cut, water added detail should be depending on the request.

(4) anchoring bolt grouting material, should agree with the following request:

 

Grouting material mixture should be poured into the bolt hole, grouting in it is strictly prohibited to vibrating, pounding, may not be adjusted after the grouting bolt;When grouting construction is not easy to directly into, choose chute auxiliary construction;Found a secrete water scene, appearance in the process of grouting should be asa grouting material dry, blot moisture.

 

Trajectory of the device, the electric china powered trolley tracks device, the device, the only difference is at the bottom of each track linking piece, adding flexible insulating plate.Copper platoon device to track copper platoon device, should choose bolt connection, namely the first track side channel steel welding, and then use copper platoon and channel steel bolt connection.Should choose copper electrode for welding connection resistance test test track and copper platoon device, need to electric china powered trolley track resistance test experiment was carried out.

 

In accordance with the practice, we choose is the multimeter, test tools such as ohmmeter, according to the practical situation, however, because the electric china powered trolley tracks are rust, surface may exist between bolt and trajectory, bad touch between bolt and steel bar, usually not practical value, cannot be accurately expresses the path resistance is to satisfy the request, so let's choose electric welding machine test, intuitive, and accurate test results.Detailed approach is: welding machine ground connection at one end in 1 on the root locus, another root locus in welding torch welding test, if the spark occurs only induction, not welding, suggests that resistance value to meet the request.If can happen welding slag, suggests that current through, resistance can't meet the request.Trajectory of shade shade into two some that some track plate and copper platoon.

 

Confirmed by construction use, track insulation resistance value of disposable test is successful, no rework, its construction work outstanding, have achieved good economic benefits.Because electric china powered trolley workshop and workshop can be useful to handle large mining company transport between doubt, not only save a lot of manpower and material resources, financial resources, also reduced the risk coefficient, improve the producing power, is the development trend in the future.
