Description

Technical Field

[0001] The utility model belongs to the technical field of suspension conveying devices, and in particular relates to a gravity-driven suspension conveying mechanism. Background Art

[0002] Overhead conveyors are a type of material handling equipment widely used in industrial production. Their primary function is to transport items via suspended tracks or chains. These devices can effectively utilize factory space, reduce ground traffic congestion, improve production efficiency, and mitigate the risks of manual handling.

[0003] Currently, overhead conveying systems on the market generally use motors and other drive devices to transport materials or products. Since these drive devices and their supporting track structures are relatively large, they often require a large space during installation and layout. This not only limits the flexibility of the overhead conveying system, but also places higher requirements on the space planning of factories or warehouses, and is costly.

[0004] Because the cargo carried in overhead conveyor systems is typically heavy, inertia can cause the conveyor cart to generate a significant impact force when the system stops. This impact can not only deform the conveyor cart's structure, affecting its normal operation, but also shorten its service life. Furthermore, on downhill sections of track, gravity can cause the conveyor cart and its loaded workpieces to accelerate downward, leading to slippage. This not only increases mechanical wear but can also cause damage to the workpieces through collisions. An uncontrolled conveyor cart can pose a threat to operators, resulting in unforeseen safety incidents and financial losses. Utility Model Content

[0061] Example 2

[0062] This embodiment introduces a gravity driven suspension conveying mechanism, please refer to Figure 4 As shown, further introduction is given based on the above embodiments.

[0063] Figure 4 This is a schematic diagram of the clamping cylinder structure. The clamping cylinder 2 includes a cylinder body 201, a fixing screw hole 202, a piston rod 203, and an air hole 204. The cylinder body 201 is provided with a fixing screw hole 202 and an air hole 204. The piston rod 203 is provided at the output end of the cylinder body 201.

[0064] The working principle of the clamping cylinder 2 mainly includes three aspects: air source supply, cylinder piston movement, and clamping force transmission. First, the air source enters the cylinder body 201 through the air hole 204 in the air path system, pushing the piston rod 203 to move. During the clamping operation, the air source enters one side of the cylinder body 201, pushing the piston rod 203 to move to the other side, thereby achieving the purpose of clamping the workpiece; during the release operation, the air source enters the other side of the cylinder body 201, pushing the piston rod 203 to move to one side, releasing the workpiece. Secondly, the movement of the piston rod 203 of the clamping cylinder 2 is transmitted to the piston rod 203 through the pressure of the air source, thereby generating a driving force to achieve clamping or release of the conveying trolley 1. Finally, the clamping cylinder 2 transmits the clamping force to the conveying trolley 1 to achieve clamping or release of the conveying trolley 1.

[0065] The technical effect of this embodiment: The clamping cylinder assembly provided in this application is a modular part, and multiple clamping cylinders can be arranged in the conveying track according to the use requirements. It has a good braking effect, can be operated flexibly, and is easy and convenient to install.

[0066] Example 3

[0067] This embodiment introduces a gravity driven suspension conveying mechanism, please refer to Figure 5 As shown, further introduction is given based on the above embodiments.

[0068] Figure 5 This is a side view of the conveying mechanism structure of a gravity-driven suspended conveyor line. The walking wheel 103 is located on the inner side of the conveying track 3, with the bottom end close to the conveying track 3 and a gap between the outer side and the inner wall of the conveying track 3; sliding is achieved by the friction rotation between the walking wheel 103 and the track.

[0069] The outer end of the guide wheel 104 is close to the inner end surface of the conveying track 3, and the guidance is achieved by the friction rotation between the guide wheel 104 and the inner end surface of the track.

[0070] The piston rod 203 in the clamping cylinder 2 passes through the conveying track 3, a nut is provided near the end of the cylinder body 201, and a washer and a nut are provided at the end not near the cylinder body 201, which are fastened to the conveying track 3; the cylinder body 201 is provided outside the conveying track 3.

[0071] The operating principle of the mechanism is as follows: the clamping cylinder 2 is arranged at the upper end of the conveying trolley 1. When the mechanism is used, considering that it relies on the deadweight of the material on the hanger of the conveying trolley 1 to drive, the conveying track 3 needs to be installed at a certain angle, which is at least 3°; when the conveying trolley 1 is on the conveying track 3, it will naturally move downward under the action of gravity, and the angle of the conveying track 3 will have a certain influence on the acceleration of the trolley.

[0072] When the conveying trolley 1 is sliding down, in order to prevent a serious collision due to excessive speed, a clamping cylinder 2 is set on the conveying track 3. When the clamping cylinder 2 contracts, since the conveying track 3 has a certain toughness and the contraction amount is very small, the conveying track 3 is contracted inward and at the same time tightly clamps the guide wheel 104 of the conveying trolley 1. The conveying trolley 1 will be braked and slowed to a stop in time, and then the clamping cylinder 2 will extend, the conveying track 3 will return to its original state, and the conveying trolley 1 can continue to move forward.

[0073] The technical effect of this embodiment: This application is composed of mechanical components, and the conveying track is suspended obliquely in the air, and the transportation work is completed by the gravity of the material itself, which can significantly reduce the dependence on electricity or other forms of energy; compared with traditional transportation methods that require continuous power input, the gravity-driven transportation system has lower construction and maintenance costs; and the setting of this application occupies a small space and is applicable to a wide range of scenarios.

[0074] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as within the scope of protection of the present invention.
