[0002] With the rapid development of urbanization, subways are the commuting mode for most people. In the complex subway system, equipment that provides passenger guides, train information, and other content is needed. Usually, such equipment is installed on the wall of the subway platform or hoisted on the top of the station hall to display the real-time arrival information of the train and other related information in a striking way. However, the traditional display screen hoisted in the station hall often has only two directions of display at most, and the display area is small, and the display effect is not good; there are already display modules that display large and multiple screens on the market. This display module is composed of multiple large display screens, which can achieve display effects on four or more sides, and can provide passengers with ultra-large screen displays and more detailed information. However, during the actual installation of the equipment, it is encountered that due to its large size and weight, the reserved space is extremely small, which makes the traditional installation method unable to meet its installation requirements. Therefore, a hoisting device and its system are needed to solve the construction and installation problems of large display modules. Summary of the invention

[0015] The motor 2, the reducer, the slider, the guide rail and the sensor are connected to a monitoring switchboard via wireless signals.

[0016] Furthermore, the inner frame realizes the translational movement of the display module in the X and Y directions within its range.

[0041] The inside of the boom is provided with limit blocks, namely, the upper boom limit block 7 and the lower boom limit block 9, which are used for limit protection of boom extension and retraction; after the boom is set at a certain height, it can be mechanically locked to ensure the safety protection of the device after positioning, which is equivalent to the boom mechanism 1 being provided with triple safety protection measures;

[0044] The outer frame 14 is connected to the suspension rod connection seat 13. The size of the outer frame 14 can avoid interference with the air duct or bridge in the subway station hall, and can also ensure the structural rigidity of the adjustment mechanism;

[0045] The inner frame 15 can realize the translation movement of the display module 4 in the X and Y directions within its range. The driving assembly composed of the motor 16, the reducer 17, the slider 18, the guide rail 19 and the sensor 20 can ensure the accuracy of its movement.

[0046] A mounting hole is reserved at the lower end of the XY direction adjustment mechanism 2 for mounting a device base 21 of the display module horizontal adjustment device 3 .

[0047] The display module level adjustment device 3 includes a device base 21, an upper bearing 22, a rotating shaft 23, a motor 3 24, a lower bearing 25 and a device connecting block 26, etc.;

[0048] The device base 21 and the device connecting block 26 are connected and fixed by an internal motor, and a bearing device is provided at their relative position, so that the two parts can be finely adjusted in height up and down, thereby adjusting the level of the display module 4 at multiple points. The specific parameters of the adjustment value are obtained based on the feedback data of the level sensor 27 inside the display module 4.

[0049] The display module 4 includes a module frame 29, a display 28 and a level sensor 27;

[0050] The module frame 29 is mainly designed to install the display 28, and the specific shape can be customized; to ensure the level of the display module 4;

[0051] A level sensor 27 is designed inside the module frame 29 to perform motor drive fine adjustment through sensor data feedback, thereby ultimately achieving level adjustment of the display module 4 .

[0052] The installation and adjustment device assembled from the above components, combined with electrical components, constitutes the entire hoisting installation and adjustment system. While meeting the traditional installation requirements of the equipment, it solves a series of problems encountered in the hoisting installation of large display modules; and considering the safety issues of subsequent maintenance, relevant mechanisms are specially designed for maintenance use.

[0053] In the present invention, each electronic device is connected to the monitoring switchboard via wireless signals or wired lines.

[0054] Specifically, the present invention is applicable to an installation and adjustment device for hoisting large display modules, and a multi-point connection method can be adopted. This case takes a four-point connection method as an example to introduce the specific details in detail; the purpose of the installation and adjustment device is to install the large display module 4 to a designated area according to the equipment requirements, adjust the relative position according to the actual situation on site, and realize the adjustment of its adaptive level.

[0055] Structural description of the present invention: one end of the suspension rod mechanism 1 is installed on the top of the wall in the subway station hall, and the other end of the suspension rod mechanism 1 is connected to the XY direction adjustment mechanism 2. The suspension rod mechanism 1 can realize the lifting action in the vertical direction (Z direction), and can lift or lower the display module 4 to the target height (H); the XY direction adjustment mechanism 2 is fixed under the suspension rod mechanism 1, and realizes the position adjustment function in the X and Y directions within the plane range;

[0057] The working principle of the present invention is: the communication mode of CAN bus is adopted to meet the high-speed data transmission between multiple nodes, and realize the high real-time performance and high reliability of the system;

[0058] This system is controlled by a main controller and can be remotely controlled by remote control; it is mainly composed of 4 subsystems (Z axis, X axis, Y axis, horizontal axis), and the Z axis sub-control system forms a closed-loop control through multiple motors and sensors; through multiple sensors at the Z axis, its relative position (i.e. the height H between the display module 4 and the ground) is determined, and the main controller sends a signal command, and the 4 sub-controllers of the Z axis execute the action command, and at the same time realize the synchronous action of the 4 motors, and mechanically lock it after the height position is positioned to maintain the height of the display module 4 from the ground, thereby ensuring the viewing angle of the display, which is more in line with ergonomic design; the control method of the X and Y axes is consistent with that of the Z axis, and within its travel range, it can be driven by the motor to translate in two directions, and its specific position is determined according to the actual situation, and then the position can be locked.

[0059] Finally, the level sensor inside the display module 4 detects the angle difference of the display module 4 relative to the horizontal plane, and the data is fed back to the main control controller to drive each sub-control motor to perform fine adjustment, thereby ensuring the relative level of the display module and the ground of the subway station hall.
