5results about How to "Safe entry" patented technology

The utility model relates to the technical field of milling machine fixtures, in particular to a milling machine fixture which comprises a base and a sliding block arranged on the base in a sliding mode, a fixed clamping plate and a movable clamping plate are further arranged on the base, the fixed clamping plate is fixedly installed on one side of the base, and the movable clamping plate is fixedly installed on the sliding block. A first air cylinder is fixedly installed on the base, and a piston rod of the first air cylinder is connected with the sliding block. The base is provided with a bearing face, a penetrating opening is formed in the bearing face, and a bearing piece is arranged at the penetrating opening, the bearing piece is used for assisting a workpiece in entering and exiting from a clamping area, contact between a worker and a clamp can be effectively reduced, and the worker is prevented from being hurt by clamping force of the clamp due to the fact that the workpiece is manually placed in the operation process; through the assistance of the bearing plate, the workpiece can enter a clamping area safely and stably and retreat smoothly after machining is completed, and safety and working efficiency are effectively improved.

The utility model discloses a bath tub of collapsible storage. Including the cylinder, the water storage pool is seted up on the cylinder, the side surface of cylinder is hinged with a footboard, the bottom surface of footboard both ends is hinged with the support foot, the bottom surface of footboard is hinged and is connected with the hydraulic pressure rod, the other end of hydraulic pressure rod is formed hinged connection with the side surface of cylinder. The utility model discloses a footboard that is bound together with the cylinder is set up, so that the user can use the footboard as a step to more conveniently and safely step into the bathtub. At the same time, the footboard and the support foot are both provided in a folding structure, so that the footboard and the support foot can be quickly folded and stored when idle, achieving the effect of hiding and not occupying extra space.

This application provides a robot control method, system, device, electronic device, and storage medium, relating to the field of robot technology. The method includes: when a robot travels to the waiting area of ​​a first elevator and the current task path indicates that it needs to enter the elevator car, and / or, when the robot is inside the elevator car and the current task path indicates that it needs to exit the elevator car, controlling the robot to acquire first environmental information regarding the direction of the elevator door; wherein a first marker is provided at a first designated location inside the elevator car, and a second marker is provided at a second designated location in the environment to which the waiting area of ​​the first elevator belongs; if the first environmental information indicates the presence of a marker in the environment, and the height difference between the marker and the robot satisfies a preset leveling condition, then the robot is controlled to travel according to the current task path. This ensures the robot can safely enter or exit the elevator car, improving the safety of robot operation.

The invention discloses a device for pouring a telescopic receiving hopper, and relates to the technical field of concrete pouring. The material receiving device comprises a material receiving device body, and an adjusting mechanism and a vibrating mechanism are arranged in the material receiving device body; a material receiving hopper is arranged on one side of the material receiving device body, when slurry falls off from a discharging opening, the design of the material receiving hopper can effectively prevent the slurry from dripping on a track and the ground, and waste of the slurry and environmental pollution are avoided. The slurry is guided to flow into the waste pit, so that collection and treatment of all the slurry are ensured, the remaining slurry can be reused or properly treated, through the arranged adjusting mechanism, when low-viscosity slurry is discharged, slurry splashing can be reduced through adjustment of an adjusting rod, liquid is prevented from being splashed to an unwanted area, and the use effect of the slurry is improved. Therefore, it is ensured that slurry enters the receiving hopper safely and accurately, waste is reduced to the maximum extent, and for high-viscosity slurry, it can be ensured that sticky slurry smoothly flows into the receiving hopper by adjusting the inclination angle of the receiving hopper.

This invention relates to a combined tool for extended reach casing and cementing. A float collar, a bypass valve, and an oscillating device are sequentially screwed onto the top of the power guide shoe. The oscillating device's oscillating shaft, from top to bottom, comprises an upper connector, a hexagonal tenon, a polished rod section, and a threaded section. A spring sleeve is screwed onto the upper part of the threaded section of the oscillating shaft. Disc springs are stacked above the spring sleeves, each disc spring fitting around the outer circumference of the polished rod section. A spring plug is pressed above the disc springs, and a hexagonal hole is provided along the axis of the spring plug, fitting onto the hexagonal tenon. A spring cylinder is screwed onto the lower outer circumference of the spring plug. The inner cavity of the spring cylinder has an inner step, located below the threaded section and spaced at intervals. An oscillator is installed below the inner step, its bottom abutting against the top of the lower connector. The upper external thread of the oscillating lower connector is screwed into the lower port of the spring cylinder. This tool can generate self-excited vibration, reducing friction, increasing casing running speed, and improving cement stone strength and cementing quality.
