Description

Non-cantilever type lifting machine

Technical Field

The utility model relates to a lifting machine, especially a non-cantilever type lifting machine.

Background

In an automatic production line or a material conveying system, the situation that a height difference exists between two conveying belts or conveying mechanisms often occurs, so that a lifting mechanism needs to be arranged between the two conveying mechanisms with the height difference, the conveying mechanism with the first height conveys materials to the lifting mechanism, the lifting mechanism acts to lift (or lower) the materials to a height matched with the conveying mechanism with the second height, and in a traditional lifting machine, a bracket directly bearing the materials is of a cantilever structure, so that a certain overturning moment can be generated at the far end of a connecting position, the bracket can be integrally inclined when the overturning moment is too large, and if the inclination degree is too large, the materials on the conveying mechanisms can be clamped when the materials move to the bracket. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed, can guarantee lift platform's both sides all atress at the lift in-process to prevent its lifting machine because of cantilever structure produces the problem of overturning moment.

The technical solution of the utility model is that: a non-cantilever type lifting machine comprises a frame 1 and is characterized in that: the lifting device is characterized in that a lifting platform 2 is connected to the rack 1 in a sliding manner, a plurality of transmission rollers which are parallel to each other are rotatably supported on the lifting platform 2, all the transmission rollers are driven by a transmission roller driving mechanism, a lifting motor 4 is further arranged at the bottom of the rack 1, an output shaft of the lifting motor 4 is connected with a driving shaft 5 which is rotatably supported at the bottom of the rack 1 through a sprocket transmission pair, a center wheel 6 is arranged at the center of the driving shaft 5, a pair of first driving wheels 7 are symmetrically arranged on the driving shafts 5 at two sides of the center wheel 6, a pair of second driving wheels 8 which are respectively matched with the two first driving wheels 7 are arranged at the top of the rack 1, two lifting belts 9 are wound and supported between the first driving wheels 7 and the second driving wheels 8, a weight box 10 is arranged on the two lifting belts 9, and the two lifting belts 9 are also connected with the side A of the lifting platform 2, center wheel 6 is last to be supported there is central area 11, the both ends of central area 11 all link to each other with weight box 10, the top of weight box 10 still is provided with balanced area 12, the other end of balanced area 12 changes the direction back through setting up two sets of fixed pulleys 13 on frame 1 top, with lift platform 2's B side links to each other, just A side and B side are two relative sides on lift platform 2.

Compared with the prior art, the utility model, have following advantage:

this kind of structural style's non-cantilever type lifting machine, its simple structure, design benefit, and reasonable layout, it is to in the traditional lifting machine, the lifting platform that directly is used for supporting the work piece is cantilever type structure and all sorts of problems that lead to, a special structure is designed, the lifting machine of this kind of structure need not increase extra supporting mechanism or hoist mechanism, only utilize a plurality of hold-in ranges and rather than supporting fixed pulley assembly, just realized supporting and connecting simultaneously to two relative sides of lifting platform, thereby prevent that lifting platform is in the cantilever state in the course of the work, and then avoided the lifting platform slope that probably appears, the work piece can't follow the transport mechanism and move to lifting platform etc. a great deal of problem. The non-cantilever type elevator with the structure has the advantages of simple manufacturing process and low manufacturing cost, so the non-cantilever type elevator has various advantages, is particularly suitable for popularization and application in the field, and has very wide market prospect.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: the utility model provides a non-cantilever type lifting machine, includes frame 1, sliding connection has lift platform 2 on this frame 1, it has many driving rollers that are parallel to each other then to rotate to support on lift platform 2, all driving rollers all drive through driving roller actuating mechanism, the bottom of frame 1 still is provided with elevator motor 4, elevator motor 4's output shaft passes through the sprocket drive pair and links to each other with the driving shaft 5 that rotates the support in frame 1 bottom, the center department of driving shaft 5 is provided with centre wheel 6, then is provided with a pair of first drive wheel 7 symmetrically on the driving shaft 5 of centre wheel 6 both sides, the top of frame 1 is provided with a pair of second drive wheel 8 with two first drive wheel 7 phase-matchs respectively, twine jointly between first drive wheel 7 and the second drive wheel 8 and support there are both sides elevator belt 9, be provided with weight box 10 on the both sides elevator belt 9, simultaneously both sides elevator belt 9 still links to each other with lift platform 2's A side, it has central band 11 to support on the centre wheel 6, the both ends of central band 11 all link to each other with weight box 10, the top of weight box 10 still is provided with balanced area 12, the other end of balanced area 12 changes the direction back through setting up two sets of fixed pulleys 13 on 1 top of frame, with lift platform 2's B side links to each other, just A side is two relative sides on lift platform 2 with the B side.

The utility model discloses non-cantilever type lifting machine's working process as follows: the elevator is arranged between two conveying mechanisms with height difference, materials are moved to a lifting platform 2 of the elevator by a first conveying mechanism, then the lifting platform 2 drives the materials to move longitudinally, the materials move to a height position matched with the first conveying mechanism and stop moving, a driving roller on the lifting platform 2 acts to convey the materials to a second conveying mechanism, and therefore the conveying work of the materials between the two conveying mechanisms with height difference is achieved;

when the lifting platform 2 needs to do longitudinal movement, the lifting motor 4 is controlled to work through the control system, the lifting motor 4 drives the driving shaft 5 to rotate through the sprocket transmission pair, so that the central wheel 6 and the pair of first transmission wheels 7 arranged on the driving shaft 5 can drive the central belt 11 and the lifting belts 9 on the two sides to move, as the central belt 11 and the lifting belts 9 are both connected with the weight box 10 of the lifting platform 2, the movement of the central belt 11 and the lifting belts 9 on the two sides can drive the lifting platform 2 and the weight box 10 to do longitudinal movement (the movement directions of the two are opposite), as the end part of the balance belt 12 connected with the top end of the weight box 10 is connected with the side B of the lifting platform 2, and the side B is opposite to the side A of the lifting platform 2 connected with the lifting belts 9, which is equivalent to that the lifting belts 9 and the balance belts 12 respectively support (pull) the lifting platform 2 from the two opposite sides, both sides of the lifting platform 2 are stressed, namely a non-cantilever type structure; the non-cantilever structure can ensure that the lifting platform 2 has stable posture in the longitudinal movement process and cannot incline due to the fact that the lifting platform receives overturning moment, and therefore the reliability of the lifting machine in the working process is ensured.
