Abstract
The utility model relates to a power transmission apparatus for construction lifting machine which includes a current collector and a sliding touch guide rail etc. The sliding touch guide rail is connected with the standard knot through a guide rail bracket arranged at the distance of per three meter. The contact on the current collector always maintains contact with the copper bar on the guide rail, and the outer power supply can enter into the cage through the guide rail. The power transmission apparatus for construction lifting machine of the utility model is realized, and the utility model has the following advantages: high safety, long service life, low cost and wide range of application.
Description
Technical field:
The utility model relates to a kind of power transmitting device of building hoist, the particularly high-rise and superelevation layer power transmitting device of building hoist.
Technical background:
Along with high speed development of national economy, building hoist begins bringing into play enormous function in growing field.But, owing to use the continuous expansion in field, cause existing building hoist technology more outstanding with the contradiction of reality, power transmitting device is one of wherein distinct issues.Existing building hoist is directly to enter elevator craning cage by cable to transmit electricity, the length of cable along with lift the requirement of maximum height of stroke do not change simultaneously, just the cable length of the long more lift of stroke is long more, but when the setting height(from bottom) of lift surpasses 150 meters, the rubber and the copper cash of cable rupture easily, have strengthened difficulty of construction; When setting height(from bottom) surpassed 300 meters, the enlarged diameter of cable had been brought very big difficulty to existing building hoist structural configuration, and,, cause the loading capacity of lift to reduce along with the increasing of cable length because building hoist itself need bear the cable deadweight, high highly more, loading capacity is more little.Simultaneously since cable with the upper and lower operation of lift determined cable in use to occur beating to turn round through regular meeting, defective such as outer rubber breakage, the fracture of copper cash middle part or rubber wear out, so just hamper building hoist and playing a role in the field widely.
Summary of the invention:
The purpose of this utility model provides a kind of pattern that existing lift is transmitted electricity by cable that changed, and can guarantee that the load-carrying of lift is stable, and is safe in utilization, the life-span is long, cost is low, scope of application building hoist power transmitting device more widely.
Realize building hoist power transmitting device of the present utility model, comprise formations such as the current collector that is installed on the elevator craning cage and conduction wiping guide rail on the structure, contact on the current collector contacts with bus on the conduction wiping guide rail, and the bus and the power supply of conduction wiping guide rail link.
As improvement of the present utility model, conduction wiping guide rail is divided into nodular, mutual superposition is installed, can or reduce directly by increasing or reduce conduction wiping guide rail and save and realize according to the increase of setting height(from bottom), so just solved the shortcoming that the cable of existing lift can not arbitrarily extend, more convenient to use.
As improvement of the present utility model, conduction wiping guide rail is connected with the lift standard knot by support, and conduction wiping guide rail installs and fixes reliably, has guaranteed cage in the process of upper and lower operation, and power supply remains on-state.
As improvement of the present utility model, the skin of described conduction wiping guide rail is the Al-alloy metal layer, and internal layer is an insulating barrier, on insulating barrier, be provided with groove, described bus is embedded in the groove, makes conduction wiping guide rail, bus more durable, uses safer.
Realize building hoist power transmitting device of the present utility model, have that safe, long service life, cost are low, a scope of application advantage more widely.
Description of drawings:
Fig. 1 is the schematic diagram of building hoist of the present utility model.
Fig. 2 is that the part of conduction wiping guide rail of the present utility model is analysed and observe schematic perspective view.
Fig. 3 is the schematic perspective view of current collector.
Fig. 4 is the schematic perspective view of conduction wiping guide rail joint.
Embodiment:
As Fig. 1, Fig. 3, shown in Figure 4, the electric installation of building hoist comprises current collector 3 and the conduction wiping guide rail 5 that is installed on the cage 4.Conduction wiping guide rail 5 is connected with standard knot 1 by support 2.Conduction wiping guide rail 5 is connected with external power 6.As shown in Figure 2, the conductive copper bar 7 on the conduction wiping guide rail 5 contacts with the contact of current collector 3, and external power 6 constantly is sent to power supply 6 sources on the current collector 3 by wiping guide rail 5, to cage 4 power supplies, guarantees cage 4 trouble-free operations by current collector 3.The skin of conduction wiping guide rail 5 is the Al-alloy metal layer, and internal layer is an insulating barrier, is provided with groove on insulating barrier, and conductive copper bar 7 is embedded in the groove.Building hoist power transmitting device of the present utility model has that safe, long service life, cost are low, a scope of application advantage more widely.
