Description

Technical Field

[0002] Intelligent logistics is the use of advanced Internet of Things technologies such as barcodes, radio frequency identification technology, sensors, and global positioning systems through information processing and network communication technology platforms. It is widely used in basic activities such as transportation, warehousing, distribution, packaging, loading and unloading in the logistics industry, realizing the automated operation and efficient optimization management of the cargo transportation process, improving the service level of the logistics industry, reducing costs, and reducing the consumption of natural resources and social resources. In one of the links, a vertical lift is required. Usually, a hollow shaft reduction motor is used to synchronously output power to both sides to drive the left and right synchronous wheels to rotate, so as to achieve synchronous lifting of the left and right sides. This structure has a large lifting stroke, low requirements for the output torque of the motor, and is belt-driven, with high stability. It is a commonly used design structure for lifts. In order to meet the stability requirements, double sliding rods are used in the lifting structure on both sides. In order to ensure smooth sliding, the design precision of the structural parts is high, resulting in too high processing costs. In addition, it is not easy to find the center and adjust the center when the equipment is installed, and the installation and debugging are cumbersome. When the equipment is lifted, when the lifting speed is too fast, the linear bearing makes too much noise, the overall working reliability is poor, and the service life is short.

[0030] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0031] like Figure 1-Figure 9 As shown, the automatic shock-absorbing and centering lifting mechanism dedicated to the intelligent passenger inspection system of this embodiment includes a frame 14, a fixed base plate 12 is arranged at the middle position of the bottom of the frame 14, a motor 9 and a reducer 10 are installed on the base plate 12, and a symmetrical rotating shaft 11 is output at the output end of the reducer 10. The rotating shaft 11 is installed with a main shaft through a coupling 8, and a belt transmission mechanism 6 is installed on the main shaft. Two groups of belt transmission mechanisms 6 are symmetrically arranged on the left and right sides of the frame 14, and a connecting member 17 is fixed to the transmission belt of the belt transmission mechanism 6 through a tooth plate 16. A lifting plate 5 is fixed above the connecting member 17, and a roller line assembly 4 is fixed above the lifting plate 5 through a fastener. A luggage tray 15 is placed above the roller line assembly 4, and the operation of the belt transmission mechanism 6 drives the roller line assembly 4 to move up and down; guide shaft assemblies 13 are respectively installed at the four corners of the lifting plate 5.

[0032] The installation structure of the guide shaft assembly 13 is as follows: it includes a guide shaft body 1302, the guide shaft body 1302 is connected to the lifting plate 5 through a linear bearing 18, a guide shaft limit block 1301 is provided on the top surface of the guide shaft body 1302, the guide shaft limit block 1301 is fixed to the upper part of the frame 14, and a floating joint 1303 is provided on the bottom surface of the guide shaft limit block 1301, and the floating joint 1303 is fixed to the lower part of the frame 14.

[0033] The lifting plate 5 adopts a thin plate structure.

[0034] The lifting plate 5 is provided with a plurality of mounting holes and weight-reducing holes.

[0035] The connecting member 17 is a "7"-shaped structure, which can conveniently connect the tooth plate 16 and the lifting plate 5 on the transmission belt, ensure the reliability of the connection, and is also convenient to disassemble during replacement and maintenance.

[0036] A protection frame 7 is provided outside the single belt transmission mechanism 6 , and the protection frame 7 is fixed on the frame 14 .

[0037] The cross section of the protection frame 7 is a "┏┓" structure.

[0038] A stainless steel sealing plate 3 is installed on the outer side of the frame 14 .

[0039] A protective plate 1 is installed above the sealing plate 3 via a mounting plate 2 .

[0040] The sealing plate 3 and the protective plate 1 can play an effective protective role.

[0041] In actual working process:

[0042] When it is necessary to descend, the motor 9 and the reducer 10 work to drive the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the belt transmission mechanism 6 to work. The belt transmission mechanism 6 drives the entire lifting plate 5 to descend under the action of the connecting piece 17. During the descent, due to the action of the floating joint 1303, universal tilting can be achieved. The guide shaft limit block 1301 is made of flexible material and can also be freely adjusted. The linear bearing 18 can realize automatic centering to ensure that the lifting plate 5 with the roller line assembly 4 and the luggage tray 15 can descend smoothly. Conversely, when rising, the same working principle can also achieve a smooth rise without jamming or vibration.

[0043] The front and rear ends of the utility model are connected and installed with conveying rollers respectively, and the heights of the conveying rollers at the front and rear ends are different. The lifting work of the utility model can meet the work of the entire frame return circulation.

[0044] The design precision of the utility model is reduced, and the processing cost is greatly reduced. The utility model is easy to install as a whole, and does not require much debugging work. Through the action of the guide shaft assembly 13, the entire lifting is smoother, without jamming and vibration, and with low noise.

[0045] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
