Description

Eccentric polished rod conveying mechanism of suspension type gallows couple fulcrum

Technical Field

The invention relates to the field of mechanical transfer, in particular to a suspension type hanger hook fulcrum eccentric polished rod conveying mechanism.

Background

With the development of industrial technology, various automatic production lines are widely applied, a logistics conveying system is an important component of the production line, the conveying system can be divided into plane conveying and suspension conveying according to spatial layout, and at present, suspension conveying mainly adopts a suspension chain conveyor, a horizontal chain conveyor and a suspension rail self-propelled trolley.

The three suspension type conveying technologies have advantages and disadvantages, and the existing disadvantages are difficult to change due to the mature technology.

The hanger of the suspension chain conveyor moves on the suspension guide rail through a chain, so that the purpose of conveying packing materials is achieved. The overhead track constitutes a closed loop on which the carriage runs. The main disadvantages are: the sling carries the articles and is hinged with the carriage, the suspension chain conveyor cannot transfer the articles from one conveying line to another; the structure is complex and the energy consumption is high.

The horizontal chain conveyer consists of driving unit, horizontally installed chain and its accessories, chain wheel, tension unit, guide track and its installation accessories. The main disadvantages are: the chain is horizontally arranged, a large tensioning force is needed, the longer the conveying distance is, the larger the tensioning force is, the requirement on the structural strength of the whole conveyor is high, and the chain wheel and the chain are easy to wear; the lubricating oil needs to be lubricated regularly and cannot be used in the industries of clothing, food, chemical industry and the like; the structure is complex and the cost is high; the failure rate is high.

A suspended rail self-propelled trolley is an article carrying device which runs in an air track and consists of a track, a trolley set, turnouts, a slide conduction power taking device (part of trolleys are driven by a storage battery, and the power taking device is replaced by an automatic charging device), a lifting device, an electric control device and the like.

A suspension type hanger hook fulcrum eccentric polished rod conveying mechanism comprises a polished rod, a hanger and a motor, wherein the polished rod is connected with an output shaft of the motor, and the hanger is connected to the polished rod in a sliding manner;

the hanger comprises a vertical rod, an upper hook, an eccentric part and a bent rod, wherein the upper hook is fixedly connected to the upper end of the vertical rod, the eccentric part is fixedly connected to the inner side of the upper hook, and the bent rod is fixedly connected to the lower end of the vertical rod;

a first eccentricity e1 exists between the contact point position of the eccentric part and the polished rod and the central point position of the upper hook, and a second eccentricity e2 exists between the central point position of the upper hook and the central point position of the bent rod.

Preferably, the polished rod is connected with an output shaft of the motor through a connecting piece.

Preferably, the first eccentricity e1 is greater than the diameter of the upper hook and less than twice the diameter of the upper hook, and the second eccentricity e2 is 3-5 times the first eccentricity e 1.

Preferably, the bottom of the bent rod is fixedly connected with a lower hook.

Preferably, the polished rod is rotatably connected below the roof.

The invention has the advantages that:

the mechanical structure is extremely simple. The device mainly comprises a power device, a polished rod, a mounting accessory and a hanger, wherein the polished rod is a conveying guide rail and can provide conveying thrust.

The hanger rail is convenient to change. The gallows top does not have and shelters from, and the gallows vertical direction snatchs and put down more conveniently, when needs trade the rail, only needs to dial the gallows couple to perpendicular with the polished rod axis, and the gallows can stop at the position of snatching, is convenient for snatch the mechanism and snatch the gallows and convert to on other tracks.

The cost is extremely low. The parts are few, the parts are convenient and cheap to manufacture, no lubrication is needed, and the manufacturing and maintenance cost is low.

The reliability is high. No complex movement and mechanism, and no failure.

The safety is high. If the hanger is blocked and cannot move due to other mechanisms or external force, the hanger only slips on the polish rod, and mechanical failure is not easy to generate.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

As shown in fig. 1 to 5, the device comprises a polished rod, a hanger and a motor, wherein the polished rod is connected with an output shaft of the motor, and the hanger is connected on the polished rod in a sliding manner;

Fig. 3 shows a close-up of the hanger hook, the eccentric part 103 under the upper hook 102 is deviated to the left side of the hanger, the eccentric part 103 is contacted with the polished rod 1 when the hanger 2 is hung on the polished rod 1, and the hanger 2 is also designed to be eccentric as shown in fig. 2 for keeping balance.

Fig. 4 shows the eccentricity schematic diagram of the upper hook 102, the eccentric member 103, and the vertical hanger rod 101 of the hanger 2, where a first eccentricity e1 is between the contact point of the eccentric member 103 and the polished rod 1 and the central point of the upper hook 102, and a second eccentricity e2 is between the central point of the upper hook 102 and the central point of the bent rod 104, and due to the eccentricities e1 and e2, the hanger 2 may tilt when the polished rod 1 rotates under the action of gravity.

Because the upper hook 102 of the hanger 2 has the eccentricity e1, when the polished rod 1 rotates, the friction force is applied to one side of the polished rod 1 where the eccentric part 103 contacts, and the upper hook 102 is pushed to deflect, as shown in fig. 5, so that the friction force applied to the eccentric part 103 by the polished rod 1 generates an axial component force, and the hanger 2 is pushed to move axially along the polished rod 1, thereby achieving the purpose of logistics transportation.

The specific implementation mode and principle are as follows:

by setting, a first eccentricity e1 between the contact point position of the eccentric member 103 and the polish rod 1 and the central point position of the upper hook 102 is larger than the diameter of the upper hook 102 and smaller than twice the diameter of the upper hook 102, and a second eccentricity e2 between the central point position of the upper hook 102 and the central point position of the curved rod 104 is set to be 3-5 times the first eccentricity e 1.

Due to the eccentricity e1, e2, the hanger 2 tilts when the polished rod 1 rotates under the action of gravity.

Therefore, when the polished rod 1 rotates, the friction force is applied to one side of the polished rod 1 contacted with the eccentric part 103, which pushes the upper hook 102 to deflect, as shown in fig. 5, so that the friction force applied to the eccentric part 103 by the polished rod 1 generates an axial component force, which pushes the hanger 2 to move axially along the polished rod 1, thereby achieving the purpose of logistics transportation.

Based on the above, the invention is driven by sliding friction force, has simple mechanical structure, convenient rail replacement of the hanger and low cost, and the hanger only slips on the polished rod, thereby being difficult to generate mechanical failure and having high safety.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
