The entrusting leads are fixedly arranged on the top of the two ends of the wall pole, the pulley wheels of the single wheel cable pulleys ride on the intrusting leads, the lower parts of the single wheel cable pulleys are hung with two core cables by a cable hanging pin axis, the single wheel cable pulleys are connected with the bridge crane by the draughting leads, the top of the bridge crane is provided with the lead blocking frame, the single wheel cable pulleys are connected by the draughting leads and the cable. The utility model can be used in the places which have special requirements of fireproofing and explosion proofing, reaches the effects of safe use, and the utility model has simple installation, low cost, small voltage of the circuit and can save the energy and reduce the wastage.
Description
Technical field
The utility model relates to a kind of electric supply installation of handling machinery, especially bridge crane power safety electric supply installation.
Background technology
The cart supply power mode of the general electric overhead travelling crane that uses of factory floor mainly is the angle steel slide block type, has H type, U type, X type to slip power transmitting device.The common feature of their three phase mains supply power mode is to contact conduction by the isometric electric conductor of conductive slider and workshop length, and moving and sliding conduction with bridge crane.Its shortcoming is that charged electric conductor and slide block expose when sliding more or less, contact badly, and the electric spark generation is just arranged, and in the environment that fire prevention, explosion-proof or specific safety requirement are arranged, just can not use.Besides the contact conduction has the voltage drop loss, and energy loss is big.
The utility model content
The purpose of this utility model provides a kind of bridge crane power supply device, this electric supply installation is when bridge crane moves, do not produce electric spark, also not having charged object exposes in air, really reach the requirement of safe handling, and this electric supply installation installation is simple, cost is low, the line voltage distribution pressure drop is little, and is energy-saving and cost-reducing.
To achieve these goals, bridge crane power supply device of the present utility model is made up of wall column, holder rope, two single-wheel cable coasters, pull rope, cable, cable blocking frame, bridge cranes at least, the holder rope is fixed on the top of two ends wall column, the sheave 1 of single-wheel cable coaster " is ridden " on the holder rope, the single-wheel cable coaster links to each other with bridge crane by pull rope, also be provided with cable blocking frame on the bridge crane, a plurality of single-wheel cable coasters link to each other with cable by pull rope.
Used pull rope between the utility model electric supply installation single-wheel cable coaster, its rope is long less than the cable length between the single-wheel cable coaster.
A holder rope drum is installed in the utility model bridge crane top.
Holder rope in the utility model can be installed in directly over the crossbeam of bridge crane on the free-throw line with the bridge crane parallel track.
The single-wheel cable coaster is provided with the pull rope aperture and hangs the cable bearing pin, and it is rotatable to hang the cable bearing pin.
Mutually when disturbing, it is sagging that draught line is catenary, because it is rotatable to hang the cable bearing pin, makes cable be the lemniscate type and shrink at coaster for pull rope or cable between the single-wheel cable coaster.
Use the bridge crane power supply device of this utility model, power supply does not expose, during the bridge crane operation, no electric spark produces, can use in the place of specific safety requirements such as preventing fires, explosion-proof, reach the effect of safe handling, and this device is installed simply, cost is low, the line voltage distribution pressure drop is little, can save energy.

Fig. 2 single-wheel cable coaster is installed schematic views.
Fig. 3 single-wheel cable coaster structural representation.
Fig. 4 double girder overhead crane cart power supply device execution mode.
Can see that from Fig. 2 and Fig. 3 single-wheel cable coaster 1 is provided with a lead aperture and hangs cable Bearing pin 9, the sheave 10 of single-wheel cable coaster 1 " are ridden " on holder rope 2.
Can find out from single-beam crane power supply device embodiment shown in Figure 1, all The sheave 10 of single-wheel cable coaster 1 all " is ridden " at the holder rope 2 that is fixed on above two end wall columns 8 On, each single-wheel cable coaster bottom hangs three-core cable 3, each single-wheel cable by hanging cable bearing pin 9 Be connected to each other by seizing wire pull rope 4 between the coaster, and with mono beam crane in bridge type 7 on link to each other, Mono beam crane in bridge type 7 tops are equipped with holder rope drum 5, and the holder rope is played supporting role.
Can find out twin beams from Fig. 4 double girder overhead crane cart power supply device embodiment Bridge crane power supply device and the difference of mono beam crane in bridge type cart power supply device exist Above the crossbeam of dolly 11 at double girder overhead crane of double girder overhead crane 12, the holder rope drum Height must be higher than the height of dolly 11, other with mono beam crane in bridge type cart Power supply Install identically, no longer repeat.
Embodiment
Single-beam crane cart power supply device as shown in Figure 1, all single-wheel cable coasters 1 all " are ridden " on the holder rope 2 that is fixed on above the two ends wall column 8, each single-wheel cable coaster bottom hangs three-core cable 3 by hanging cable bearing pin 9, connect by seizing wire pull rope 4 between each single-wheel cable coaster, rope is long less than the cable length between the two-wheeled, when the single-wheel cable coaster is drawn close mutually, it is sagging that pull rope is catenary, cable is the lemniscate type and shrinks, the single-wheel cable coaster links to each other with mono beam crane in bridge type by pull rope, the holder rope drum is installed in the top that is higher than mono beam crane in bridge type 7 crossbeams, and holder rope is played supporting role, prevents to hold in the palm rope sag and is pulled.When mono beam crane in bridge type 7 moves forward, pass through pull rope, single-wheel cable coaster advanced in unison, cable is many catenaries to launch, and when mono beam crane in bridge type retreated, cable blocking frame 6 was pushed cable and single-wheel cable coaster to rear, a plurality of coasters are drawn close mutually, cable is the lemniscate type and shrinks being parallel to bridge crane crossbeam direction, and the shared space of cable and single-wheel cable coaster is less, does not influence the stroke of bridge crane.
Double girder crane cart power supply device as shown in Figure 4, be that with the mono beam crane in bridge type difference dolly 11 of double girder overhead crane 12 is above the crossbeam of double girder overhead crane, the height of holder rope drum must be higher than the height of dolly 11, its embodiment and single-beam crane cart power supply device principle basically identical, repeated description no longer here.
