Abstract
The utility model relates to an automatic plate turnover device for a sliding contact line trench. By the automatic plate turnover device, a vehicle can safely cross a trench and a track under the condition of safe and stable running of a crane, thereby effectively preventing wheels of the vehicle from sinking into the sliding contact line trench and damaging sliding contact lines, and also improving the utilization rate of a crane field. The automatic plate turnover device is characterized in that four sliding contact lines are arranged, a three-phase four-wire system is adopted; three of the wires serve as power wires, and the rest one serves as a special connecting wire; the ground resistance of the vehicle in running is less than 4 ohms; and an angle between a movable turnover plate and an embedded seat is 165 to 170 degrees, thereby reducing the influence on the traffic. The automatic plate turnover device for the sliding contact line trench has the characteristics of simple structure, high safety and reliability and low manufacture cost.
Description
Technical field
The utility model relates to transfer crane accessory equipment technical field, especially a kind of automatic panel-turnover device of trolley trench.
Background technology
Transfer crane is used quite extensive in commercial production, as mine, metallurgy, machine manufacture etc., usually be installed on open-air transfer crane and the trolley trench be installed on the crane track next door, trench is parallel to track, width is generally about 500mm, the hoisting crane cross sill connects with trolley by transmission arm, makes to guarantee that hoisting crane moves back and forth in orbit.Trench is unenclosed construction usually and is located at track one side.In actual the use,, in the time of need passing trench and track as vehicle, must stop the hoisting crane operation, install cover plate additional for open type ground groove structure temporarily, wheel is not absorbed in the trench, after vehicle passes through, recover former state according to the difference of field condition.When how to keep crane operating status, make vehicle safety by seeming necessary.
Summary of the invention
The purpose of this utility model is the automatic panel-turnover device of a kind of simple in structure, safe and reliable hoisting crane trolley trench of design.The technical solution of the utility model is so to realize:
A kind of automatic panel-turnover device of trolley trench, comprise the trench that is located at crane track one side and be located at the interior trolley of trench, trolley links by transmission arm and ground hoisting crane cross sill, described trench top is provided with one group of drop in leaf, described drop in leaf be located at underground pre-buried seat and pass through hinge-coupled, angle between drop in leaf and the pre-buried seat is 165-170 °, and transmission arm is provided with the traction rollers that contacts with drop in leaf, and the number of described trolley is 4.
As preferably, the width of described drop in leaf is greater than the trench width.
As preferably, described trolley adopts three-phase four-wire system, and three is power lead, and one is special-purpose wiring line.
The utility model has designed a kind of automatic panel-turnover device of trolley trench, under the hoisting crane normal operating condition, keep the automatic open and close of turnover panel on the trolley trench, under the situation that guarantees the crane safety smooth operation, vehicle can be safely by trench and track, prevent that effectively wheel of vehicle is absorbed in the trolley trench and damages trolley, also improved simultaneously the degree of utilization in hoisting crane place, the trolley number increases to 4, adopts three-phase four-wire system, and three is power lead, one is special-purpose wiring line, the grounding resistance that guarantees driving is less than 4 ohm, and the angle design of drop in leaf and pre-buried seat is between the 165-170 degree, reduces current influence.The utlity model has characteristics simple in structure, safe and reliable, low cost of manufacture, easily apply.
