The utility model relates to the technical field of lifting equipment, in particular to a trolley chassis with a boom type steering structure. A trolley chassis with a boom type steering structure comprises steering wheels used for controlling and driving a trolley to move and steer, power wheels used for controlling and driving the trolley to move and brake, a frame used for installing the steering wheels, the power wheels and a control system assembly of the power wheels, and the steering wheels are controlled to swing through a swing oil cylinder and achieve steering control. The two ends of the swing oil cylinder are connected with the steering wheels on the two sides of the vehicle frame in a control mode and are synchronously controlled in a telescopic mode. The two ends of the two-way oil cylinder are connected with the steering wheels on the two sides of the frame respectively, synchronous stretching and retracting and same-angle steering of the steering wheels on the two sides are achieved through driving of the hydraulic system, the problem that steering is not synchronous due to mechanical gaps, response lag and the like in a traditional multi-motor or multi-steering-engine system is effectively solved, the advancing track of the trolley is more accurate, and the stability is higher. And the stability and the safety during steering are obviously improved.

The endoscopic treatment tool includes: a tip cap disposed at a tip portion of an endoscope body; the rotating ring is configured to be capable of rotating around the tip cap, and a surgical instrument is attached to the rotating ring; the driving part is configured to control the rotating ring to rotate relative to the tip cap; the surgical instrument is detachably connected with the rotating ring, and when the rotating ring rotates, the surgical instrument can be driven to rotate relative to the tip cap.

The invention relates to a deformation monitoring type self-elevating tower, and relates to the technical field of tower structures and monitoring, the deformation monitoring type self-elevating tower comprises a platform, height adjusting mechanisms and a deformation monitoring mechanism, the bottom of the platform is symmetrically provided with a plurality of groups of height adjusting mechanisms, and the height adjusting mechanisms are provided with the deformation monitoring mechanism. The height adjusting mechanisms at the bottom of the platform are used for adjusting the height of the platform to adapt to different terrains or load conditions, the deformation monitoring mechanisms are integrated on the height adjusting mechanisms to monitor deformation (such as bending and inclination) of the tower structure in real time and feed back data to the control system, and when it is monitored that deformation exceeds a safety threshold value, the control system controls the control system to operate. The system can automatically trigger height adjustment or give an alarm, self-adaptive adjustment of the height of the tower and deformation real-time monitoring are achieved, the height adjusting mechanism is allowed to flexibly adapt to the uneven ground, the deformation monitoring mechanism can give an early warning of structural failure in advance, and the accident risk is reduced.
