Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of transportation track technical field, more specifically, it relates to a kind of transportation main road parallel mechanism. BACKGROUND

[0002] In the traditional transportation system, materials are usually transported on a single track. When it is necessary to transfer materials from one track to another, i.e., parallel operation, there are often some problems. For example, the existing parallel mechanism may have a complex structure, resulting in high installation and maintenance costs. Or the parallel process is not smooth enough, which can cause material jamming, falling, and other issues, affecting transportation efficiency and material safety. Moreover, when the transportation speed is high, the traditional parallel mechanism is difficult to effectively control the speed and direction of the transportation carrier (such as a transportation tool with a carrier), which can easily cause the transportation carrier to deviate from the track, leading to safety accidents and equipment damage and production stoppage. SUMMARY

[0003] To overcome the shortcomings of the prior art, the utility model aims to provide an efficient, accurate, and stable transportation main road parallel mechanism.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a transportation main road parallel mechanism, comprising a chain track, a cross beam vertically arranged above the chain track, and a carrier running track horizontally arranged below the chain track and fixedly connected through a main rail hanger. A parallel assembly is arranged between the cross beam and the chain track, and the parallel assembly is located above the carrier running track. The parallel assembly comprises a straight rail, a curved rail, and an elastic track connected in sequence. The parallel assembly is configured to guide the carrier to enter the elastic track from the curved rail when the carrier slides down from the straight rail, and the carrier generates a force on the elastic track through its own gravity, causing the elastic track to rotate downward and fit with the carrier running track, thereby stably entering the carrier running track.

[0005] The utility model is further provided with a limiting unit above the straight rail, which comprises a bracket fixed on the cross beam, a cylinder arranged on the bracket, and a stop block penetrating through the top of the bracket and hinged with the cylinder joint. The stop block is fixed in the bracket by a latch, forming a rotary connection.

[0006] The utility model is further provided with an upper swing head connected with the curved rail and a lower swing head hinged with the upper swing head, and a clamping groove for installing a return spring is arranged at the connection between the upper swing head and the lower swing head.

[0007] The utility model is further provided with a guide block above the elastic track, which is fixed on one side of the chain track through a mounting plate.

[0008] The utility model further sets up: the bracket top plate is equipped with the baffle of rotating groove and is equipped with fixed baffle below, the baffle is hinged in rotating groove front end, and make the baffle limit and guide to baffle.

[0009] The utility model discloses the beneficial effect is:

[0011] 2. The cylinder and the baffle in the limiting unit work together, the cylinder can control the rotation of the baffle. When it is necessary to control the timing of the carrier entering the lane assembly, the baffle can be lowered by the cylinder to block the carrier; when the conditions are met, the cylinder retracts to raise the baffle, allowing the carrier to smoothly enter the straight rail and slide down, making the time control of the carrier lane process more accurate, avoiding the carrier from entering the lane assembly too early or too late, ensuring that the lane process is carried out in an orderly manner, improving the coordination and stability of the entire transportation system, the bracket is fixed on the crossbeam, providing a stable support structure for the cylinder and the baffle, the entire limiting unit structure is relatively simple, the connection between the cylinder, the baffle and the bracket is clear, and when a component fails, it is easy to disassemble and replace.

[0012] 3. The elastic track is divided into an upper swing head and a lower swing head, and a clamping groove is arranged at the connection for mounting a return spring. When the carrier passes through, the upper swing head and the lower swing head can independently and flexibly buffer the impact force of the carrier under the action of the return spring, so that the elastic track can better adapt to carriers of different weights and speeds, reduce the hard collision between the carrier and the track, effectively protect the carrier and the articles carried by it, and at the same time prolong the service life of the elastic track itself. After the carrier leaves the elastic track, the upper swing head and the lower swing head can quickly return to the initial position under the elastic force of the return spring, which ensures that the elastic track can continuously perform the next lane work without manual intervention, greatly improves the working efficiency and automation degree of the lane mechanism, and meets the continuous and efficient transportation demand.

The bracket top plate is provided with a rotating groove, and the stop block is hinged at the front end of the rotating groove, which provides a precise rotating track for the stop block. When the stop block is driven to rotate and lift by the cylinder, the rotating groove can effectively guide the movement direction of the stop block, ensure that the stop block stably blocks or releases the vehicle, avoid abnormal situations such as jamming and deviation of the stop block during movement, and further improve the accuracy of the timing control when the vehicle merges. The bracket below is provided with a baffle for fixing the stop block. During the rotation of the stop block, the baffle can limit and guide the stop block. When the stop block descends to block the vehicle, the baffle limits the rotation angle of the stop block to prevent the stop block from rotating excessively, and ensures that the stop block stably plays a blocking role. When the stop block rises to release the vehicle, the baffle also plays a guiding role, so that the stop block smoothly returns to the initial position, enhances the stability and reliability of the stop block work, and protects the normal operation of the whole transportation system.

[0020] For ease of description, spatially relative terms, such as "upper", "lower", "left", "right", and the like, are used herein for the purpose of illustrating one element or feature's relationship to another element or feature, as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if a device is inverted, elements described as being "below" or "beneath" other elements or features would then be oriented "above" the other elements or features.
