Background technology

The belt conveyer telescopic device at head mainly applies to the place that thermal powerplant, goods station, metallurgy, chemical enterprise etc. use fixed belt conveyer, to realize many emptying points of fixed belt conveyer transit crossconnect.

The mode of position, conventional many emptying points transit crossconnect adopts the four-way piece combination of surging of electro-hydraulic dynamic three-way pipe or electricity to make and be used for realizing.This mode be applicable to neighbor distance nearer and the emptying point in the transhipment below 3, be not suitable for a plurality of emptying points transit crossconnect greater than 3.Adopt electro-hydraulic dynamic three-way pipe or the electricity four-way piece array configuration of surging if surpass the movement system in 3 emptying points; Then need higher height and bigger space to realize transit crossconnect; The cost of whole movement system is very high; And each change-over point all need make electricity consumption the stretching of push rod of surging realize conversion, if a change-over point intact transit crossconnect that do not become that breaks down is then arranged.

The existing domestic belt conveyer telescopic device at head of using always is mainly in the thermal powerplant coal handling system and uses; Be applicable to that the little bandwidth load-transfer device that is not more than 1400mm, total shift motion are not more than the transit crossconnect system of 7000mm; Can't realize that big bandwidth is greater than the load-transfer device of 1400mm, the total shift motion transit crossconnect greater than 7000mm; And all adopt the rack-and-gear type of drive, the tooth bar requirement on machining accuracy is high, and then can't use as if the broken teeth phenomenon; Adopt portable carrying roller group layout, must increase the required distance of shift motion, required driving power when palpus increase drive carrying roller group moves when mobile.

Along with production-scale raisings such as thermal powerplant, goods station, metallurgy, chemical enterprises, more than two kinds of forms can not satisfy use.

Summary of the invention

In order to overcome existing shortcoming in the existing belt conveyer transit crossconnect system, the utility model provides the fixing belt conveyer telescopic device at head that drives down.This device is fixed in ground through driver element; Output shaft links to each other with two pin wheel group transmission devices through coupler; Two pin wheels are meshed with the pin gear mechanism that is installed on walking car beam down either side; Drive walking car beam and move, solve that big bandwidth conveyer is remote, the technical matters of many emptying points transit crossconnect.

The scheme that the utility model technical solution problem is adopted is:

Be expert at and be respectively arranged with shock absorber, head funnel, discharge roll, anchoring device, walking wheels, groove profile carrier roller group, rail clamping device, pin gear mechanism, backhaul cleaning carrying roller group and cylinder synchronously on the mule carriage beam; Walking car beam direction along ng a path moves; Track is fixed on the built-in fitting, and the track both ends are provided with the stop device, and the pin gear mechanism is fixed on the walking car beam; Driver element carries out transmission through the engagement of pin wheel group and pin gear mechanism; Resting barrel and fixed frame are fixed on the built-in fitting, and suspension carrying roller group is fixed on the fixed frame, and transport tape is installed between suspension carrying roller group and the discharge roll.

Good effect; The output shaft of the driver element of the utility model through motor, reductor and electrical controller will be housed links to each other with two pin wheel group transmission devices through coupler; Two pin wheels are meshed with the pin gear mechanism that is installed on walking car beam down either side; Drive walking car beam and move, solved the technical matters of the remote transit crossconnect of big bandwidth conveyer, enable to carry out multiple discharge.The movement system in the suitable remote stroke of big bandwidth belt conveyer, many emptying points is installed and used.
