Description

Technical Field

[0001] The invention relates to the technical field of shuttle transport, and in particular to a circular track type shuttle auxiliary transport device. Background Art

[0002] The shuttle vehicle is a convenient intra-workshop transport vehicle that can quickly transport goods to designated areas. The only area where outside cooperation is required is loading and unloading.

[0003] Since the path that the shuttle needs to pass through is set, the limit on the stacking height of the goods is fixed. However, in the process of transporting goods, it is difficult for us to determine the height of the stacked goods every time. This puts forward new requirements for the cargo loading and unloading process of the shuttle, and it is necessary to quickly determine the stacking height of the goods. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a circular track shuttle auxiliary transport device to solve the problem of quickly determining the height of cargo stacking.

[0005] Based on the above purpose, the present invention provides a circular track shuttle auxiliary transport device, including a shuttle, two installation grooves, which are arranged on the upper surface of the shuttle, and the two installation grooves are parallel to each other and respectively close to the two ends of the shuttle; two lifting brackets, which are respectively arranged in the two installation grooves; two support bars, which are respectively arranged on the top of the two lifting brackets; a pressure switch, which is arranged on the upper surface of the shuttle; an alarm system, which is arranged on the side of the shuttle and is electrically connected to the pressure switch; when loading, the lifting bracket is raised to the highest height, and the goods to be loaded are placed on the two support bars. Under the action of the gravity of the goods, the lifting bracket descends, and after the bottom of the goods touches the pressure switch, the alarm system sounds an alarm, prompting that the goods are full and no more goods should be loaded.

[0006] The top area of ​​the shuttle is fixed. Since the stacking height limit is fixed, the total weight limit for transporting goods of different densities is different. By understanding the added density of the transported items, we can know the approximate range of the weight limit each time. After determining the approximate range of the weight limit, we can limit the height of the goods stacking by limiting the weight of the goods to be loaded and unloaded, thereby solving the problem of quickly determining the height of the goods stacking.

[0007] As a further improvement of the present application, the distance between the two installation grooves is greater than half of the length of the shuttle and less than four fifths of the length of the shuttle.

[0008] As a further improvement of the present application, the lifting bracket includes two fixed mounting blocks, respectively arranged in the two mounting grooves; two hydraulic telescopic rods, one end of which is rotatably connected to the fixed mounting block by a pin shaft, and the other end is provided with a movable block; two support frames are respectively arranged in the mounting grooves, and are rotatably connected to the fixed mounting block and the movable block in each of the mounting grooves by a pin shaft, including a first support rod and a second support rod, the middle part of the first support rod and the middle part of the second support rod are connected by a rotating shaft, and have a degree of freedom of rotation between each other; the lower part of the first support rod is rotatably connected to the movable block by a pin shaft; the lower part of the second support rod is rotatably connected to the fixed mounting block by a pin shaft; it also includes two upper sliding blocks, the two upper sliding blocks are respectively connected to the upper part of the first support rod and the upper part of the second support rod by a pin shaft; the lower end of the support bar is provided with a slide groove, and the two upper sliding blocks are embedded in the slide groove.

[0009] As a further improvement of the present application, the hydraulic telescopic rod is a hydraulic rod with adjustable pressure, which will be compressed to a contraction length when the pressure is greater than the adjusted pressure.

[0010] As a further improvement of the present application, a stabilizing support block is further provided in the installation groove, and the stabilizing support block is arranged in the installation groove at one end close to the movable block, and the heights of the fixed installation block, the movable block and the stabilizing support block are equal, which is equal to the depth of the installation groove.

[0011] As a further improvement of the present application, the cross-section of the slide groove is an inverted "convex" shape, and the cross-section of the upper slider is also an inverted "convex" shape. The two cooperate with each other, and the upper slider only has the freedom to move back and forth along the slide groove.

[0012] As a further improvement of the present application, a connecting rod is further provided between the two lifting brackets.

[0013] As a further improvement of the present application, the annular track shuttle auxiliary transport device also includes two distance detection units, which are respectively arranged in two installation grooves, and are used to detect the heights of the two support bars; the distance detection units are electrically connected to the lifting bracket; when the difference in the height values ​​of the two support bars detected by the two distance detection units exceeds a set difference, the lifting bracket below the support bar with a higher height value is lowered with the smaller height value as the reference, until the difference in the height values ​​of the two support bars is less than the set difference.

[0014] As a further improvement of the present application, the distance detection unit includes a label arranged at the bottom of the support bar and a laser rangefinder arranged in the mounting groove. The laser rangefinder detects the distance value by reflecting laser onto the label, and then obtains the height value.
