Description

The automatic loading and unloading transport trolley

The utility model relates to a kind of automatic loading and unloading transport trolley, and it integrates lifting, transportation, unloading three big functions, uses when being particularly suitable for loading and unloading of concrete prefabricated member factory and transportation prefabricated components.

The products benzene of concrete prefabricated member factory is heavy, size is long, transportation and dangerous when loading and unloading, expense is high again.Factory generally adopts half machinery or manpower to load and unload at present.Then to adopt the horizontal dress of trac. during transportation, also need be with the alongshoreman simultaneously.Exercise on highway like this, promptly super wide, people's goods loads in mixture again, and traffic accident takes place easily, can't freely come in and go out side street, lane.Also little, not only costly, also time-consuming, the effort of the while transportation volume of one coastiong.

The purpose of this utility model is to provide a kind of automatic loading and unloading transport trolley that integrates lifting loading, transportation, unloading three big functions for people.

The utility model partly is made up of support, column, hydraulic actuator, jack, crane arm, change speed gear box, little driving, railway carriage, drawbar frame and brake assembly etc.Support, column all are positioned at the end that railway carriage links to each other with drawbar frame, between the two for flexibly connecting.Crane arm one end and jack all are clipped between the two clamping plates on column top.Change speed gear box, little driving are installed on the crane arm, and two fixed pulleys at they and crane arm two ends are serially connected by wirerope, are connected to suspension hook under the little driving, can move around on crane arm under the effect of change speed gear box.Jack one end withstands under the crane arm, and the other end links to each other with hydraulic actuator.

The utlity model has following advantage:

(1) simple in structure, cost is low; (2) adopt hydrostatic drive, need not power supply; (3) be applicable to the town and country different kinds of roads, the road surface wide cut gets final product greater than 1.5 meters; (4) of many uses, can be used for transporting prefabricated object, high-tension bus-bar bar, timber, sheet material, various steel, pipeline and heavy type and purchase part etc.; (5) use, keep in repair safe ready.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the example structure scheme drawing.

Fig. 2 is the birds-eye view of Fig. 1.

Fig. 3 is the left view (amplification) of Fig. 1.

Referring to each accompanying drawing, main composition of the present utility model partly has support 1, column 2, hydraulic actuator, jack 3, crane arm 4, change speed gear box 5, little driving 6, railway carriage 7, drawbar frame 8 and brake assembly 9 etc.Railway carriage 7 is equipped with leftover bits and pieces assembly and wheel 21 in the bottom.Drawbar frame 8 by hanging joint 20, drag thick stick 19, the pin basket 18 of standing, bracing frame 23, permanent seat 24 5 parts constitute, by station pin frame 18 and drag thick stick 19 to link to each other with railway carriage 7.Two permanent seats 24 that are used for fixing bracing frame 23 lay respectively at pin frame 18 both sides, station, are made by angle steel or reinforcing bar, are rectangular in shape, and the one end is welded on the support 1, on the other end welding station pin frame 18.Bracing frame 23 can be extracted out from permanent seat 24, and it stretches out the adjustable feet 25 of an end strip length.After the length adjustment of feet 25 is good, use latch locking.Support 1 is installed in be connected with drawbar frame 8 end of an end of railway carriage 7, by two pillars 33 and go up, in two whippletrees 34,35 constitute, be framed structure.In order to make support 1 more firm, support 1 both sides respectively are provided with a lacing wire 17, and lacing wire 17 1 ends link to each other with pillar 33 upper ends of support 1, and the other end links to each other with the station pin frame 18 of drawbar frame 8.Bearing 36,37,38 is equipped with respectively in column 2 upper, middle and lower portions, wherein go up, in the bearing seat of two bearings 36,37 be connected on the whippletree 34,35 of support 1 by sieve bar, the bearing seat of lower bearing 38 then is installed on the railway carriage 7, column 2 rotation under external force like this, thus flexible connection formed with support 1.Clamping plate 10 have two, are positioned at column 2 tops, and they are tightly clamped column 2 by upper and lower each two holder 39,40, and clamping plate 10 are fixed together by sieve bar with 39,40 of holders.Crane arm 4 links to each other with latch with clamping plate 17 tops, and speed-change gear box 5 and little driving 6 are housed on it, and the fixed pulley at they and crane arm 4 two

ends

13,14 is serially connected by wirerope 15.Two of wirerope 15 is separately fixed at the two ends of little driving 6.Manual turntable 16 is housed in the rotating shaft of speed-change gear box 5, and little driving 6 bottoms link to each other with the lifting wirerope 11 of band suspension hook 12.The rotation manual rotating disk, little driving 6 can move around on crane arm 4 under the drive of guiding principle cable 15.Owing to connect by bearing 36,37 formation activities between column 2 and the support 1, so crane arm 4 can column 2 be rotating shaft, Rotate 180 in the horizontal direction.。For preventing crane arm 4 because of stressed excessive torsional deflection, crane arm 4 is provided with a string lacing wire 41, and its two ends link to each other with crane arm 4 two ends respectively, and by post 42 stretchings.Crane arm 4 is withstood at jack 3 tops that are clipped in clamping plate 10 bottoms, and both link to each other by latch, and its other end is connected with the connection pipe 26 of hydraulic actuator.Hydraulic actuator is formed by connecting in turn by connection pipe 26, distributing box 27, high-pressure pipe 28, high-pressure oil pump 29, oil suction pipe 30, fuel tank 31, oil return pipe 32, and oil return pipe 32 1 ends link to each other with fuel tank 31, and the other end is connected with distributing box 27.Distributing box 27 is installed on the whippletree 34 at support 1 middle part, and 31 of fuel tanks are installed in frame and sail seat 22 right sides, and high-pressure oil pump 29 links to each other with the transmission device of haulage tractor head.

During use, earlier two bracing frames 23 are extracted out, adjusted feet 25 length, and latch locking, to stablize whole transport trolley; Parallel motion crane arm 4 moves on to the object present position with it then, and the rotation manual rotating disk 16 again, and little driving 6 is gone ahead, and uses the suspension hook that links to each other with little driving 12 that object is hooked; At this moment start distributing box 27, jack 3 is risen crane arm 4 jack-up, so just object can be sling; Promote object subsequently, it is parallel with railway carriage 7 that object is slowly moved, and rotation manual rotating disk 16 moves little driving 6 backward again, start simultaneously distributing box 27 again, jack 3 retractions, crane arm 4 descends thereupon, unclamp suspension hook 12 then, object can be placed in the railway carriage 7.
