4results about How to "Less stuck" patented technology

The utility model discloses a kind of crushing and shunting device and pollution cleaning robot, crushing and shunting device is set to the front end of the advancing side of pollution cleaning robot, the crushing and shunting device includes crushing unit and the shunting unit being set to the both sides of the crushing unit, the crushing unit is for crushing the sundries of the advancing side of the pollution cleaning robot, the shunting unit is for carrying the sundries after crushing and shunting it to the both sides of the pollution cleaning robot.In the crushing and shunting device provided in the present application, the crushing unit can effectively push away, break and separate the obstacles to both sides for preliminary processing, and then the obstacles can be shunted to both sides through the shunting unit, thereby shunting and processing the obstacles in complex environment, reducing resistance while greatly reducing the possibility of getting stuck or damaged due to inhaling foreign matter during work.

The utility model discloses a kind of stable drive structure of hanger for electroplating production line, it is related to electroplating equipment technical field, include drive assembly, drive assembly is installed on electroplating production line, drive assembly includes transmission chain and the drive gear for driving transmission chain movement, the outside of transmission chain is fixedly provided with multiple racks, multiple racks are continuously and aligned, each rack has array distribution tooth profile structure, tooth profile structure is located rack far from transmission chain side;Hanger body, hanger body is slidably installed on electroplating production line, the three pawls of each ratchet of the scheme are staggered and size decreases, can be simultaneously engaged with the three tooth profile structures adjacent on rack, through multiple teeth contact dispersion backlash error, simultaneously, the gradient design of pawl height and width can adapt to the slight deformation of rack, ensure that there is no obvious gap in meshing process, effectively avoid displacement deviation when hanger moves, reduce the risk of jamming or overlapping.

The utility model relates to the field of washers, in particular to a firm saddle-shaped washer which comprises a central part and edge parts, the edge parts are smoothly and fixedly arranged on the two sides of the central part, a central hole is formed in the central part, the central part is bent, the edge parts are also bent, each edge part comprises a bent section, and the bent sections are connected with the central hole. The bending section is connected with the central part, and the difference between the width of the central part and the diameter of the central hole is smaller than the width of the bending section. According to the utility model, the central part and the edge part are arranged, so that the bending section at the edge part can bear larger lateral force, and the possibility of bending damage in the transportation process is reduced; in addition, the horizontal section is arranged on the edge part, so that the possibility that the gasket is stressed, bent and damaged in the installation process due to the fact that the end part of the edge part is clamped with the installation plane is reduced.

This disclosure provides an obstacle-crossing method, a cleaning device, and a computer-readable storage medium, relating to the field of cleaning technology. The method is applied to a controller of a cleaning device, which includes drive wheels, casters, a chassis, and a lifting mechanism. The chassis includes a front end and a rear end, with the direction from the rear end to the front end being the forward direction of the cleaning device. In the forward direction, the casters are located between the drive wheels and the front end of the chassis. The method includes: in response to detecting an obstacle that can be crossed at the front end of the chassis, controlling the lifting mechanism to raise the chassis to a first preset height; controlling the drive wheels to move backward a preset distance towards the rear end of the chassis at a first preset speed and then braking, so that the front end of the chassis tilts due to inertia; and controlling the walking state of the drive wheels according to the detected chassis posture. The method provided by the embodiments of this disclosure is simple and can improve obstacle-crossing ability without increasing the structure of the cleaning device.
