Description

Technical Field

[0001] The present invention relates to the field of AGV, and in particular to a connecting beam used for AGV extension and retraction and capable of adapting to deformation. Background Art

[0002] AGV is the abbreviation of Automated Guided Vehicle, which means "automatic guided transport vehicle". AGV is a transport vehicle equipped with electromagnetic or optical automatic guidance devices, which can travel along the specified guidance path and has safety protection and various transfer functions. The road conditions on which AGV runs often have many potholes and unevenness. Therefore, when AGV is moving, especially at high speed, the vehicle body is required to adapt to the unevenness of the ground as much as possible, and always keep the four wheels of the vehicle body in contact with the ground to achieve stable and high-speed operation. This puts high demands on the connecting beam of the transport vehicle. The AGV of this device is used for the use of intelligent parking robots.

[0003] However, the traditional solution is generally to use expensive and complex elastic shock-absorbing mechanisms. The use of this connecting beam can adapt to the bumpy deformation of the vehicle body through its unique structure. At the same time, the structure is simple, and the manufacturing cost and installation and use costs are lower. It perfectly solves the problem that AGV is difficult to achieve high-speed and stable operation on uneven roads. To this end, we propose a connecting beam for AGV telescopic and with adaptive deformation ability to solve the above problem. Summary of the invention

[0004] The main purpose of the present invention is to provide a connecting beam for AGV telescopic and having the ability to adapt to deformation, which can effectively solve the problems in the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A connecting beam for AGV telescopic and having the ability to adapt to deformation, comprising: a left main body and a right main body, the left main body is composed of a left C-shaped main body and a left main body cover plate, the two are welded and fixed together, and the right main body is composed of a right C-shaped main body and a right main body cover plate, the two are also welded and fixed together;

[0007] An intermediate connecting beam is installed between the left C-shaped body and the right C-shaped body, and a plurality of left connecting beam welding points are arranged at equal distances between the left C-shaped body and the intermediate connecting beam, and a plurality of right connecting beam welding points are arranged at equal distances between the right C-shaped body and the intermediate connecting beam. The evenly distributed welding points can ensure that the left C-shaped body and the right C-shaped body are fixedly connected to the intermediate connecting beam, and can also make the intermediate connecting beam and the left and right bodies have certain flexibility after welding. The AGV using this connecting beam has strong stability on high speeds or uneven roads;

[0008] The upper and lower sides of the right side of the left main body are respectively fixedly connected to the upper slide rail of the left main body and the lower slide rail of the left main body, and the upper and lower sides of the right side of the right main body are respectively fixedly connected to the upper slide rail of the right main body and the lower slide rail of the right main body, the upper slide rail of the left main body and the lower slide rail of the left main body are installed in parallel, and the upper slide rail of the right main body and the lower slide rail of the right main body are installed in parallel. After the left main body upper slide rail and the right main body upper slide rail are installed, they are in a straight line, and after the left main body lower rail and the right main body lower rail are installed, they are in a straight line, and sliders are slidably installed on the outer sides of the two sets of upper and lower slide rails installed in parallel up and down, and a connecting plate is fixedly installed on the outer side of the slider by bolts, and the connecting plate is fixedly connected to the AGV main body device by bolts, so that the AGV body can slide on the connecting beam and bear the load of the AGV body.

[0009] Preferably, the left C-shaped body and the right C-shaped body are internally welded with supporting ribs, which provide strong structural strength for the left and right bodies, ensuring the rigidity and bending and torsional strength of the left and right bodies.

[0010] Preferably, the left C-shaped body and the right C-shaped body are both made of hot-rolled steel plates, which have good mechanical strength and light weight.

[0011] Preferably, circular holes are equidistantly distributed on the upper ends of the left C-shaped body and the right C-shaped body, and special-shaped holes are arranged on the sides of the left C-shaped body and the right C-shaped body. The special-shaped holes are triangular structures with good stability. While ensuring the structural strength, the structural design of the special-shaped holes and the circular holes can reduce the weight of the middle connecting beam and increase its flexibility in bending and torsion.

[0012] Preferably, an intermediate connecting beam supporting rib is provided in the middle portion of the intermediate connecting beam to ensure the structural strength when the central portion of the intermediate connecting beam is bent. A regular intermediate connecting beam opening is opened on the side of the intermediate connecting beam, which can both reduce the weight of the intermediate connecting beam and enhance the flexibility of the intermediate connecting beam.

[0013] Preferably, a left main body sealing plate and a right main body sealing plate are welded and installed on one side of the middle connecting beam, and two sets of mounting frames are symmetrically arranged on the left main body sealing plate and the right main body sealing plate. The mounting frames are fixed with limit plates by bolts, and the limit plates are used as limit devices when the connecting plates move inward.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Patent protection points:

[0016] 1. Special-shaped holes and circular holes are arranged on both sides of the middle connecting beam. The structural design of the special-shaped holes and circular holes can reduce the weight of the middle connecting beam and increase its flexibility in bending and torsion resistance. Special-shaped openings are also arranged on both sides of the left and right main bodies to reduce the weight of the beam and increase its flexibility.

[0017] 2. The evenly distributed welding points can not only ensure that the left C-shaped body and the right C-shaped body are fixedly connected to the middle connecting beam, but also make the middle connecting beam and the left and right bodies have a certain flexibility after welding. The AGV with this connecting beam has good stability at high speed or uneven roads.

[0018] 3. The connecting beam has sufficient rigidity. When the AGV uses this type of structural connecting beam, the AGV can rely on the adaptive deformation ability of the middle connecting beam when walking on uneven ground, so that the entire AGV has a certain adaptive deformation ability.
