The invention relates to the technical field of oil delivery, in particular to an oil delivery pipeline valve and a pipeline leakage emergency system.The oil delivery pipeline valve comprises a valve body, a valve seat, a gate plate, a valve deck, a sealing assembly, a valve rod and a worm and gear speed reducing motor, the worm and gear speed reducing motor is electrically connected with the pipeline sealing emergency system, and a gap is formed between the gate plate and the end face of the valve seat; a pushing device for pushing the two gate plates to move horizontally is arranged at the lower end of the valve rod; the gate plate is connected to the bottom of the valve rod through the pushing device, the gaps exist between the working face of the gate plate and the oil inlet and the oil outlet, and the gate plate is horizontally pushed through the pushing device in the downward movement process of the valve rod so that the gate plate can be attached to the oil inlet and the oil outlet; in this way, friction between the working face of the flashboard and the end faces of the oil inlet and the oil outlet is reduced, and the problem that the sealing face of the gate valve is prone to abrasion in the opening and closing process of the gate valve is solved.

This invention relates to the field of robotics and provides an adaptive robotic hand, comprising: a connecting arm connected to a predetermined position on a machine, wherein at least three gripping claws are rotatably connected to the front end of the connecting arm; a control component disposed inside the connecting arm to control the state of the gripping claws; a drive component for controlling the state of the control component is fixed on the connecting arm; and the gripping claws abut against the control component under the action of a torsion spring. By providing an automatic gripping pressure detection device, this invention ensures that whether to grip a workpiece can be determined by detecting the gripping pressure, thus adapting to the gripping requirements of different parts.

The water-based epoxy color sand filling device comprises a rear vertical plate, a top plate is fixedly connected to one side of the top of the rear vertical plate, supporting columns are fixedly connected to the two corners, away from the bottom of the rear vertical plate, of the top plate, and second telescopic rods are detachably connected to the side walls, close to the top plate, of the two supporting columns. The output end of the second telescopic rod penetrates through the supporting columns to be detachably connected with a liquid receiving plate, a conveying belt is arranged between the supporting columns and the rear vertical plate, a container is placed on the conveying belt, a baffle is fixedly connected to the side wall between the two supporting columns, and the liquid receiving plate is of an L-shaped structure. The device has the advantages that the two second telescopic rods are installed and used for controlling the liquid receiving plate, the liquid receiving plate is located below the pipeline, when filling is stopped, the pipeline is lifted firstly, then the second telescopic rods are started to move the liquid receiving plate to the position below the pipeline, and therefore dripping residual liquid can fall on the liquid receiving plate; in this way, the residual liquid is intercepted and stored, so that the residual liquid does not drop on the conveying belt.

The invention discloses a preparation method and device of an Anshan basalt stratum grouting material, and relates to the technical field of grouting. Primarily stirring the slurry; shearing and dispersing at high speed; performance detection; and a grouting step. According to the invention, the superfine fly ash microbeads, silica fume and nano-silica are compounded, and a high-speed shearing process is adopted, so that the particle size of the slurry is remarkably reduced, the flowability of the slurry is improved, and the slurry can be smoothly injected into micro cracks of anshan basalt; the main component Portland cement clinker has the characteristics of early strength and micro-expansion; the filling effect of the secondary components silica fume and nano-silica further compacts the structure of the stone body, so that the stone body has high later strength and tight cohesiveness with bedrock; under the synergistic effect of a small amount of hydroxypropyl methyl cellulose and nano silicon dioxide, segregation and bleeding of the slurry are effectively prevented, and it is ensured that the slurry is fully filled in cracks.

The utility model relates to a smoke choked flow type fireproof door, which belongs to the field of fireproof doors and comprises a door frame, a door plate, a sealing plate and a sealing device. The two door plates are rotationally arranged on the door frame; the sealing plate is arranged in the door frame and hermetically connected with the door plate; the sealing device is slidably arranged at the lower end of the door plate and protrudes out of the door plate. The door plate is provided with a separating device used for driving the sealing mechanism to move upwards. And a sealing device for driving the sealing mechanism to move downwards is arranged on the sealing plate. The sealing mechanism is used for sealing, the sealing device is driven by the separating device to be lifted up when the door is opened and closed, and the sealing mechanism is driven by the sealing device to abut against the ground for sealing when the door is closed.
