Description

V. Description of the invention (1)-[Technical field to which the invention belongs] The present invention relates to an electric mobile scaffolding device that is arranged with a plurality of scaffolds that can be moved by electric power, and can use remote monitoring devices to grasp its control status. , Especially when the electric mobile scaffold fails. [Previous technology] A mobile scaffold that can move when it houses books or other items can be gathered and distributed in a plurality of places, and a working space is formed only in front of the mobile scaffold that takes out and puts items. The limited space can be used effectively as an advantage of the article storage space. One way of moving the mobile scaffold is an electric method using a motor as a driving source. Before moving the scaffold, the required space must be formed before the scaffold to be taken out and put in. The electric scaffolding device adopts the method of specifying the space position to be formed. When the space position is specified, the correlation between the designated position and the position of each mobile scaffold at this time is used to calculate the scaffold to be moved. Instead of the moving direction, the movement of each scaffold is controlled according to the calculation result. Due to the heavy weight of the mobile scaffold itself and the need to accommodate books or other items to move here, once it starts to move, it will maintain a large amount of kinetic energy and the operator will be dangerous when caught in the mobile scaffold. The scaffolding device is assembled with various safety devices. For example, when a working space has been formed in a designated location, unless a reset operation is performed, it is interlocked, making it impossible to form another working space in another location, and making it impossible to form a new working space casually. Of the state. In addition, when the operator enters the work space to perform work, if the scaffold moves in a direction that narrows the work space,

V. Description of the invention (2) The safety bar switch is arranged horizontally by the operator pressing the loading and unloading surface (front width surface) of the scaffold item, or a part of the operator's body touches the safety bar switch , You can stop moving the scaffold on the spot. The safety bar switch mentioned above is also effective when foreign objects fall into the work space. When the above-mentioned safety bar-type switch action causes the mobile scaffold to stop on the spot, the mobile scaffold needs to be moved in the opposite direction by the operation of the emergency operation switch. After removing the operator or foreign objects between the scaffolds, it is reset to return to normal Action mode. For other safety countermeasures, there is also a dual command stop function, which is a function of stopping the movement of the scaffold immediately on the spot if it repeatedly issues a command to form a working space at another position during the movement according to the command. Moreover, alarms can be issued under certain conditions. For example, a chime or the like may be emitted during the movement of the scaffold. When the operator or foreign objects are caught in the scaffold, and the movement of the scaffold is stopped by the operation of the above-mentioned safety bar switch, an emergency will be performed. Operate to move the mobile scaffold in the opposite direction. However, during emergency operations, a lingering sound or a buzzer will sound, or a double command $ will also ring or a buzzer. There may also be cases where visual alarms such as light-emitting lights and display of monitors are used in lieu of these audio audits or alarms, or by audible alarms. Others, such as sound alarm or visual alarm, can be issued when various kinds of faults such as overheating of the motor occur. As described above, since the electric mobile scaffolding system has various complicated functions, most of the users cannot use all the complicated functions freely. For example, ‘What is the best way to move the mobile scaffold due to an emergency stop due to the safety bar-type switch’? Or if you do n’t know how to respond when some alarms are issued, there are cases where there is no failure, but normal operations cannot be restored. Of course, because of

C: \ Program Files \ Patent \ 310456. Ptd page 5 5. Description of the invention (3) 'Some failures can not restore the normal operation. In this case, according to the previous mobile scaffold structure maintenance staff, they provided suggestions by telephone in response to the user's call. If necessary, the maintenance staff went to the user to do the appropriate service. According to the user's call, the maintenance staff goes to the user to check it carefully. Most of the results only provide suggestions for the user to respond to it. Although it is a minor fault, it actually costs most of the time and cost. If the user can Reliably grasp the operation status of the mobile scaffold, and reliably transmit this to the maintenance personnel by phone, etc., the maintenance personnel can provide correct instructions, and the user can solve the fault according to the instructions. However, it is difficult to expect users to correctly grasp the operation state of the mobile scaffold. Assume that the user can correctly grasp the movement status of the mobile scaffold and can transfer this to the maintenance personnel. There are also situations in which the maintenance personnel must grasp the more detailed movement status, and in this case, the maintenance personnel must still go to the site to get started Check it out. The present invention was created in view of the problems of the prior art as described above, and its purpose is to provide a maintenance person who can grasp the control status of the mobile scaffold from a distant place, and the maintenance person can quickly move without having to go to the site. An electric mobile scaffolding device that can solve faults or other abnormal phenomena and can send control signals from remote places as needed. [Means used to solve the problem] In order to achieve the above-mentioned object, the invention described in the first scope of the patent application is arranged to control the movement of each scaffold by using a plurality of scaffolds that can be moved by electric force to have a command signal input.
