Description
Technical field
The present invention relates to a kind of hoisting crane, more specifically, relate to a kind of hoisting crane that transports article or goods, described hoisting crane has drive part, described drive part is integrally formed in main frame one side with the shape and the retarder of flange, thus with the wire reel collaborative work; And the part of advancing, the described part of advancing has by the space segment of side opening within it and is contained in wheel on the bearing of both sides, described wheel has the invoice serration teeth groove, the invoice serration gear of axis of travel of drive part of advancing inserts wherein, make the part of advancing removably be connected in the drive part of advancing, reduce the weight and volume of main frame thus, thereby obviously reduce manufacturing cost.And the drive part with retarder and drg forms an integral body, the part of advancing is removably installed with plain mode, be very easy to thereby make to install and change, reduce to safeguard and maintenance cost, obviously reduce the traffic cost of the drive part and the part of advancing, the installation after the transportation is very simple.
Background technology
Usually, hoisting crane is used in the warehouse, station and other local conveying objects or goods, and is used for the assembling/teardown of engine in factory.
Hoisting crane is a kind of machinery that uses the rope hoisting article, as a system works, and promotes article by the hook that is contained in the Wound steel rope end with primary mover, gear reduction partial sum reel.
Usually, the kind of hoisting crane comprises electric crane and air jack.Electric crane is a kind of minor crane, its middle and small motor, above be equipped with the planetary gear type speed reduction gearing reel, keep the electromagnetic braking of object and the load braking of control rate when object moves downward, all be contained in one than in the small shell.Therefore, the mode of advancing of electric crane is that the flange along I ellbeam downside is contained in cantilever or track end, thereby promotes article.Electric crane be on the ground by the manipulating wire rope in the direct motor drive mode, button mode, and remote control mode work.According to the control position and the structure of contained machine wherein, electric crane has polytype.For example, low head dummy hoisting crane is used in low position, roof, and double rail-type hoist is to use when advancing on double track.On the other hand, use air jack, be used to avoid the danger of gas burst in colliery and chemical plant.
Fig. 1 represents a kind of conventional hoist that promotes article and lateral transfer article.
As shown in Figure 1, the configuration of conventional hoist 10 is, the wire reel 12 of top Wound steel rope is contained in main frame 11 tops, traction electric machine 13 is contained in wire reel 12 1 sides, at wire reel 12 opposite sides retarder 15 that reduces winding speed and the drg 16 that stops Wound steel rope being installed, be connected on the traction electric machine 13 by tween drive shaft 14 simultaneously, its generation type is that the inside center along wire reel 12 partly supports, and before main frame 11 bottoms, the both sides, rear portion are installed wheel 18 and are connected the motor 17 of advancing, make wheel motor 17 driven in rotation of being advanced, thereby carry out lateral travel.
In above configuration, tween drive shaft 14 is housed in the hoisting crane 10, if traction electric machine 13 starts, then utilize the retarder 15 that is connected traction electric machine 13 opposite sides by tween drive shaft 14 to regulate winding speed, thereby roll the article that are transferred, wheel 18 rotations under the effect of the motor 17 of advancing then, thus articles conveyed.Picture power failure, fault etc. are taking place in emergency circumstances, the drg 16 that is contained in tween drive shaft 14 front ends starts, and winding process is stopped.
In addition, hoisting crane 10 promotes article when tween drive shaft 13 rotations that extend to wire reel 12 two ends, thereby if long tween drive shaft 14 rotates at a relatively high speed, then article may damage under the vibrations that its fast rotational process produces.For fear of this problem, tween drive shaft 14 should be in predetermined speed with interior rotation, and this will produce restriction to capacity and the speed of determining traction electric machine 13.Certainly, this also produces restriction to the Item Weight that is transferred.
In order to illustrate and to address these problems, Fig. 2 has provided another kind of conventional hoist, and it is suitable for utilizing motor rotating at high speed to carry than heavy articles.
As shown in Figure 2, the configuration of another kind of conventional hoist 20 is, be contained in wire reel 22 1 sides with the retarder 24 of traction electric machine 23 collaborative works, drg 25 is contained on the traction electric machine 23, traction electric machine 23 rotates to be wire reel 22 power is provided thus, thereby rotatable wire reel 22, retarder 24 and traction electric machine 23 are horizontally fixed on the top of the installation wire reel 22 of main frame 21, wheel 28 be contained in main frame 21 bottoms before, the both sides, rear portion, and the retarder 27 of advancing is in each wheel 28 1 side with the motor of advancing that the drg 26a that advances is housed, thereby collaborative work each other.
In above-mentioned hoisting crane 20 configurations, wire reel 22, traction electric machine 23, drg 25, retarder 24, the motor 26 of advancing, advance retarder 27 and wheel 28 are installed in the upper and lower of main frame 21 with the relation of level each other, thereby each above-mentioned part obtains horizontal fixed by occupying bigger segment space, causes structure quite huge thus.Therefore, total weight increases, and causes the capacity of advance system to become big, causes installation and tooling cost undesirably to increase.
In addition, because being used for 22 one-tenth vertical relations of support pulley 29 and wire reel of the steel rope on supporting steel wire reel 22 and the wire reel forms, therefore the differential seat angle that is transferred article when the pulling article produces power waste, just need traction electric machine 23 to have, thereby cause manufacturing cost to improve greatly than articles conveyed big capacity.
In addition, the configuration mode of retarder 24 is, gear is contained in the casing that is separated into the upper and lower part, and oil is retained in the casing, thus traction electric machine 23 is connected to wire reel 22, makes its collaborative work each other.But if system works long hours, oil may leak from connecting bridge.Retarder 24 is connected to force fit to realize with traction electric machine 23 and wire reel 22, therefore is difficult to carry out assembly and disassembly process and maintenance, thereby causes maintenance cost to raise.
In addition, wheel 28 connects the advance motor 27 and motor 27 driven in rotation of being advanced, and carries out lateral travel thus; And in this case, wheel 28 forms one with main frame 21, therefore can not separate with main frame, causes traffic cost to raise.The result is when transportation larger capacity hoisting crane, and cost of installation raises.
Summary of the invention
