Description

Electronic automatic balance keeping control device

Technical Field

The utility model relates to an electronic automatic balance keeping control device, which is used for high-altitude tower crane operation and enables a monitoring lens to automatically keep vertical and absorb shock at any time.

Background

The overhead hanging operation requires real-time cooperation of the ground, the overhead and many operators, so that a remote monitoring device needs to be installed on specific machine tools and equipment, for example: the winch for hanging the cable or the hanging (hanging) end of the hanging arm and its surroundings, etc. need to go through the remote monitoring device to let the operator know the real-time situation in a remote way, so as to facilitate the communication and operation safety of the operation.

In view of the prior proposals of CN206273762 and CN104709826, the former uses a three-way spring relationship between the damper and the axis, and the latter uses an arc-shaped groove and ball structure relationship to maintain the balance of the monitor and keep the lens at a certain stability. However, the two prior arts have a common disadvantage that the swing radian is limited, and the operation is limited in case of too large swing radian or the monitoring lens needs to rotate by a large angle. Moreover, because the requirement of hanging work safety standard, operating personnel must monitor the operation condition of hanging (lifting) tool end at any time when hanging the operation, when the arm of hanging does by a wide margin swing, in case the surveillance lens can't follow the rotation adjustment in the very first time, then will delay the activity duration greatly, efficiency is not the same.

The inventor previously invented Taiwan patent certificate No: m562411 "remote monitoring structure with automatic vertical keeping and shock absorption", which mainly utilizes a buffer component to make the monitoring device slow down the shaking and keep the balance vertical state. However, the strength of the load that the cushion assembly can withstand, as well as the time required for the speed of the cushion, are factors that affect the safety of the aerial work. In addition, external environmental factors such as: strong wind or shaking generated by load vibration of the hanging arm can cause certain interference to the monitoring equipment; then, the operator will be influenced by the monitoring screen in the remote area, and the operator cannot accurately perform the hanging operation.

In view of the above-mentioned shortcomings, and the strong wind environment of high-altitude hanging operation, the inventor proposes an electronic automatic balance-maintaining control device, which can resist strong wind and shake during operation and can carry tens of kilograms of monitoring devices; when the hanging arm rotates to enable the remote monitoring device not to be kept vertical, the balance control device can rapidly act according to the lifting or lowering of the hanging arm, and the monitoring device is kept vertical downwards at any time; and the swing angle of the balance control device is about 180 degrees, which is different from the defect of limited swing angle of the former case, and the requirement of real-time monitoring of the operation of the high-altitude tower crane is met.
