Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, in particular to a safety structure for a monorail truss cargo pickup and delivery station. Background Art

[0002] Across the vast manufacturing industry, monorail trusses, as core equipment for material handling and processing, play an indispensable role on various production lines and construction sites due to their flexibility and customizability. Based on a row of individual support structures and equipped with an advanced lifting mechanism, monorail trusses can be tailored to the specific conditions of the construction site and the characteristics of the cargo being handled, thus meeting diverse production needs.

[0003] Among the many monorail truss applications, one specially designed truss has attracted significant attention for its unique functionality and complexity. This truss not only performs the traditional duties of lifting and handling cargo, but is also cleverly installed within the loading and unloading stations, making this area both the truss's working area and the operator's activity area. This innovative design significantly improves space utilization, but it also presents unprecedented operational challenges. Since operators frequently move around the loading and unloading stations, the truss's lifting and lowering operations pose certain safety risks. Summary of the Invention

[0004] In view of the above problems existing in the existing truss work, the present invention aims to provide a safety structure for a monorail truss loading and unloading station with a simple structure and high safety.

[0005] The specific technical solutions are as follows:

[0006] A safety structure for a monorail truss loading and unloading station, comprising a drive mechanism for driving the monorail truss to rise and fall at the loading and unloading station, and comprising a detection mechanism mounted on the floor of the loading and unloading station, the detection mechanism being electrically connected to the drive mechanism and configured to detect the presence of trays or pedestrian signals on the floor of the loading and unloading station, and to feed the signals back to the drive mechanism;

[0007] The detection mechanism includes a plurality of detection parts, which are distributed in the front-to-back direction. The two detection parts located in the middle position are intermediate detection parts. When all the detection parts do not detect the disk or pedestrian signal, or any one of the detection parts detects the pedestrian signal, or only one of the intermediate detection parts detects the disk signal, the driving mechanism stops driving the monorail truss to lift. When the two detection parts detect the disk signal at the same time, the driving mechanism can drive the monorail truss to lift.

[0008] As a further improvement and optimization of this solution, the detection mechanism also includes a mounting frame, which is installed to one side of the ground at the picking and placing station, and a plurality of the detection components are installed on the mounting frame.

[0009] As a further improvement and optimization of this solution, the detection element is a photoelectric switch.

[0010] As a further improvement and optimization of this solution, the distance between the two intermediate detection member brackets matches the length of the tray.

[0011] As a further improvement and optimization of this solution, the mounting bracket is arranged along the front-to-back direction.

[0012] As a further improvement and optimization of this solution, two groups of detection mechanisms are provided and are located on both sides of the picking and placing stations in the horizontal direction.

[0013] Compared with the prior art, the above technical solution has the following positive effects:

[0014] In the utility model, when any detection piece on the picking and placing station detects a pedestrian signal, the driving mechanism stops driving the monorail truss to rise and fall for entering or leaving the warehouse. When all the detection pieces on the picking and placing station detect pedestrian signals and the two middle detection pieces detect the tray signal, the driving mechanism can drive the monorail truss to rise and fall for entering or leaving the warehouse, which greatly ensures the personal safety of the operators.

[0020] Figure 1 This is a schematic diagram of a safety structure for a monorail truss loading and unloading station in the present invention. Figure 1 FIG. 1 shows a preferred embodiment of a safety structure for a monorail truss loading and unloading station 4, comprising a driving mechanism for driving the monorail truss to rise and fall at the loading and unloading station 4, and comprising a detection mechanism mounted on the floor of the loading and unloading station 4, the detection mechanism being electrically connected to the driving mechanism and configured to detect the presence of a tray 3 or pedestrian signal on the floor of the loading and unloading station 4, and to feed the signal back to the driving mechanism;

[0021] The detection mechanism includes a plurality of detection members 1, which are distributed in the front-to-back direction. The two detection members 1 located in the middle position are intermediate detection members 1. When all the detection members 1 do not detect the disc 3 or pedestrian signal, or any detection member 1 detects a pedestrian signal, or only one intermediate detection member 1 detects the disc 3 signal, the driving mechanism stops driving the monorail truss to rise and fall. When the two detection members 1 detect the disc 3 signal at the same time, the driving mechanism can drive the monorail truss to rise and fall.

[0022] In this embodiment, when any detection piece 1 on the pick-up and placement station 4 detects a pedestrian signal, the drive mechanism stops driving the monorail truss to rise and fall for entering or leaving the warehouse. When all the detection pieces 1 on the pick-up and placement stations detect pedestrian signals and the two intermediate detection pieces 1 detect the signal of the tray 3, the drive mechanism can drive the monorail truss to rise and fall for entering or leaving the warehouse, which greatly ensures the personal safety of the operator.

[0023] Furthermore, as a preferred embodiment, the detection mechanism also includes a mounting frame 2, which is installed to one side of the ground at the pick-up and release station 4, and a plurality of detection components 1 are installed on the mounting frame 2.

[0024] Furthermore, as a preferred embodiment, the detection element 1 is a photoelectric switch.

[0025] Furthermore, as a preferred embodiment, the distance between the two intermediate detection member 1 brackets matches the length of the tray 3 .

[0026] Furthermore, as a preferred embodiment, the mounting bracket 2 is arranged along the front-to-back direction.

[0027] Furthermore, as a preferred embodiment, two groups of detection mechanisms are provided and are located on both sides of the picking and placing station 4 in the transverse direction.

[0028] Furthermore, as a preferred embodiment, handrails are provided on both sides of the monorail truss to limit the position of the materials to prevent the risk of the materials falling.

[0029] More preferably, the driving mechanism includes a storage-out button and a storage-in button:

[0030] Warehousing conditions:

[0031] The two middle detection parts 1 in the detection mechanism detect products at the same time. The other detection parts 1 cannot detect the presence of products or pedestrians. At this time, the storage button is pressed, and the driving mechanism drives the monorail truss to operate normally. During the movement of the monorail truss, if someone walks by or the signal is abnormal or there is no disk 3, the corresponding workstation storage signal is abnormal or someone walks by or there is no disk 3. At this time, the cause of the fault is found according to the fault and the lifting stops working;

[0032] Outbound conditions;

[0033] When the outbound button box is pressed, all the detection parts 1 on the ground cannot detect objects or pedestrians when outbound. Otherwise, after walking into position, the driving mechanism drives the monorail truss to stop working. At this time, the outbound signal of the corresponding workstation is abnormal, or someone has passed by, or there is no disk 3. At this time, find the cause according to the fault.

[0034] In one embodiment, the driving mechanism may include a controller and a hydraulic cylinder. The monorail truss can be raised and lowered by the hydraulic cylinder. The controller is electrically connected to the hydraulic cylinder to control the operation of the hydraulic cylinder. All the detection parts 1 are electrically connected to the controller, and each detection part 1 can send a detection signal to the controller to enable the controller to operate the hydraulic cylinder.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
