Need to prove; Be arranged on the top that promotes track 2 rotationally for the sprocket wheel in the present embodiment 4, when implementing, because the oneself height of sprocket wheel 4 and/or the existence of setting height(from bottom); Sprocket wheel 4 can be higher than the surface that promotes track 2 with the chain engages place; Make chain and the longitudinal extension direction (or traffic direction of carrying apparatus 1) that promotes track 2 that an angle (still, the projection of chain still keeps parallel, as shown in Figure 2 with the bearing of trend that promotes track 2) obliquely arranged.Such mounting means makes the pulling force of chain to carrying apparatus 1; Except the traffic direction at carrying apparatus 1 has the component; Some component that makes progress (this component is not in carrying apparatus 1 running orbit plane); Thereby reduced carrying apparatus 1 in the frictional force that promotes on the track 2, reduced frictional dissipation.Certainly, if reasons such as installing space restriction are arranged, can adjust the setting height(from bottom) of sprocket wheel 4.
Further, sprocket wheel 4 can be positioned on the longitudinal centre line that promotes track 2.Traction element 3 (being chain) need be fixedly attached to the centre position of the front end of carrying apparatus 1 like this; So that the projection of traction element 3 in the operation plane of carrying apparatus 1 is parallel with the direct of travel of carrying apparatus 1, can make carrying apparatus 1 left and right sides on lifting track 2 stressed more even like this.In addition, chain pressing plate 7 can also be set above sprocket wheel 4, with protection chain and sprocket wheel.
On the basis of the foregoing description, second end of chain can be connected with balancing weight 5, can utilize the gravity effect of balancing weight like this, makes chain in lifting process, can keep vertical.Further, can also be included as balancing weight 5 the decline track 6 that moves up and down route is provided, decline track 6 preferably vertically is arranged on the below of sprocket wheel 4, can protect balancing weight 5 and chain in lifting process, not to receive the interference or the damage of other barriers like this.
All adopted a chain to be connected to carrying apparatus in the foregoing description of the utility model as traction element; But need to prove; Can be provided with as required chain more than two or two form one group and evenly the compartment of terrain be fixedly connected on the side of carrying apparatus; And the sprocket wheel that corresponding number is set on the top that promotes track cooperates with chain, and sprocket wheel can be the chain wheel set of coaxial setting.
As another embodiment preferably; As shown in Figure 4; The drive unit of the utility model can also be included as traction element 3 provides power to make traction element 3 can draw the power part 10 of carrying apparatus 1, and second end of traction element 3 can be connected to power part 10.
Above-mentioned power part 10 may be embodied as the ring chain 11 that comprises first sprocket wheel 8, second sprocket wheel 9 and mesh said first sprocket wheel 8 and second sprocket wheel 9, and second end of traction element 3 is connected on the ring chain 11.First sprocket wheel 8 and/or second sprocket wheel, 9 positive hour hands or rotate counterclockwise, and drive ring chain 11 and rotate, and then drive the traction element 3 that is connected and move, realize promoting or transferring carrying apparatus 1.
Further, according to the demand that configuration is installed, first sprocket wheel 8 can be arranged on the top that promotes track rotationally, and second sprocket wheel 9 can be arranged on the below of first sprocket wheel 8; Guiding parts 12 is for being arranged on the fixed pulley of said first sprocket wheel 8 tops.Adopt such setting, can make full use of the lower space of the height formation that promotes track 1,, draw materials conveniently as guiding parts with fixed pulley, practice thrift cost, effect is obvious.
In addition; Fixed pulley is installed in the top of first sprocket wheel 8 in the present embodiment; Because the height and fixed pulley 12 setting height(from bottom)s of fixed pulley 12, first sprocket wheel 8 itself can produce tractive force obliquely, as stated equally; Can reduce carrying apparatus 1 like this in the frictional force that promotes on the track 2, reduce frictional dissipation.And under the prerequisite parallel with the direct of travel of carrying apparatus 1 of the projection in the operation plane of traction element 3 at carrying apparatus 1, present embodiment also can be according to the different needs adjustment fixed pulleys 12 and the setting height(from bottom) of first sprocket wheel 8.
Equally, first sprocket wheel 8 is preferably placed on the longitudinal centre line that promotes track 2.Can make carrying apparatus 1 left and right sides stressed more even like this, avoid unnecessary wearing and tearing.Correspondingly; The position that also need adjust second sprocket wheel 9, fixed pulley 12 simultaneously adapts to it; The contact point that guarantees traction element 3 and guiding parts 12 better is to the line of traction element 3 with the tie point of carrying apparatus 1, and the projection in the operation plane of carrying apparatus 1 is parallel with the bearing of trend that promotes track 2.
In the above-described embodiments, traction element may be embodied as pull rope or hauling rope etc.As stated; Equally can be as required; Traction element can be one or more pull rope or hauling rope, and a plurality of fixed pulleys are set form the fixed pulley groups and cooperate with it, and the even compartment of terrain of first end of traction element is fixedly attached to carrying apparatus; The also even compartment of terrain of second end connects a connector, is connected with ring chain by connector again; Perhaps, many group ring chain, first sprocket wheel and second sprocket wheels are set simultaneously, so that corresponding one by one with many pull ropes or hauling rope.
In the prior art, similarly motor is adopted in the outside power source of material lifting device more.The utility model also can adopt motor as power source, for above-mentioned various embodiment, can motor-driven be connected to sprocket wheel 4 or first sprocket wheel 8 or second sprocket wheel 9.The utility model also can adopt other power sources to replace motor.
In addition, the utility model also provides a kind of concrete mixing plant, and it can comprise aforesaid material lifting device.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
