7results about How to "Increase the maximum static friction" patented technology

The application belongs to the technical field of robots, and discloses a three-dimensional force sensing-based detection and balance control method and system for a legged robot. The method comprises the following steps: determining the number of the leg of the multi-legged robot that slips according to a three-dimensional force signal of the multi-legged robot in contact with the ground; and adjusting the multi-legged robot in the following manner when slipping occurs: (1) adjusting the height of the center of mass of the multi-legged robot; (2) for the leg that slips, actively adjusting the joint stiffness and joint damping of the leg to relieve instantaneous impact; applying foot end acceleration and adjusting normal support force to suppress slipping; and adjusting the target foot landing point at the next time. Through the application, the balance of the robot can be quickly restored after slipping occurs, the risk of instability is reduced, and the stability of the robot in a complex environment is ensured.

This utility model discloses an anti-slip single-sided fleece fabric, relating to fabric technology. The key technical points are: it includes a base fabric and a fleece layer; one side of the base fabric has several protrusions, which are evenly spaced along the warp direction of the base fabric. In this utility model, when the base fabric contacts the comforter, the protrusions can cause a certain deformation of the comforter's surface, thereby increasing the contact area between the base fabric and the comforter, improving the maximum static friction between them, and reducing the possibility of relative sliding. Setting the protrusions in a corrugated shape increases the length of the protrusions per unit length, thus increasing the contact area between the protrusions and the comforter. Furthermore, this shape of the protrusions increases the relative friction with the comforter in both the warp and weft directions, further reducing the possibility of relative sliding between the base fabric and the comforter.

This invention discloses a structure and design method for preventing the corner sealing gasket of a shield tunnel segment from slipping out. The structure includes a segment body, at least one anti-slip patch, and a sealing gasket. The segment body is used for forward assembly and includes four assembly end faces. A sealing ring groove is formed on the four assembly end faces. The four assembly end faces include a rear assembly end face and at least one active sliding end face located on the left and right sides. The sealing ring groove includes a first corner groove segment formed at the junction of the active sliding end face and the rear assembly end face. The at least one anti-slip patch is adhered to the groove sidewall of the corresponding first corner groove segment. The sealing gasket is ring-mounted in the sealing ring groove and abuts against the anti-slip patch. This invention solves the problem of sealing ring slippage leading to sealing failure in existing shield tunnel segment assembly structures.

The invention relates to the technical field of copper wire machining, and discloses a straightening device for high-quality copper wire manufacturing treatment for a robot, which is used for copper wire machining and comprises a workbench, a straightening assembly and a transmission assembly, the straightening assembly and the transmission assembly are arranged at the top of the workbench, and the transmission assembly comprises a plate frame and a driving motor which are arranged at the top of the workbench. The pressure adjusting opening is formed in the surface of the plate frame, the pressure adjusting plate is arranged in the pressure adjusting opening, and the driving wheel is arranged on the front face of the plate frame. According to the straightening device for manufacturing and processing the high-quality copper wire for the robot, by arranging the transmission assembly, the forward clamping force of the driving wheel and the pressing wheel on a copper wire can be actively increased, so that the maximum static friction force of the contact surfaces of the driving wheel, the pressing wheel and the copper wire is increased, and the instantaneous fluctuation resistance in the elastic straightening process is trying to be counteracted; macroscopic relative sliding is avoided; and the possibility that the copper wire is locally flattened and deformed, the surface layer is cold-hardened, the original mechanical ductility and roundness precision of the copper wire are damaged and the like is reduced.

The utility model discloses wear -resisting outdoor woven cloth relates to the fabric technology, and its technical scheme main points are: including surface layer and wear -resistant layer, one side of surface layer is equipped with the bulge, is equipped with waterproof layer on surface layer, and wear -resistant layer is fixedly connected with surface layer through the connecting strip. When using, the waterproof layer can be better protected by surface layer and wear -resistant layer by the contact of wear -resistant layer and ground and the contact of surface layer and picnic mat supported object, so that the waterproof layer is not easy to wear and tear, thereby can better guarantee the waterproof capacity of woven cloth, when there is object and press on the surface layer, the gravity of object is pressed on wear -resistant layer through the bulge, makes the side of wear -resistant layer and ground and forms the uneven surface, improves the maximum static friction between wear -resistant layer and ground, and the outer wrapping yarn of using chinlon fibre production can better guarantee the wear resistance of wear -resistant yarn.

This invention discloses an intelligent sorting device, belonging to the field of logistics equipment technology. The intelligent sorting device includes a support frame, a main conveyor belt, and sub-conveyor belts. It also includes: an identifier containing the address information of packages mounted on the main conveyor belt; a guide plate, with the movement direction of the sub-conveyor belts forming an acute angle with the movement direction of the main conveyor belt, a rotating shaft connected to one side of the guide plate, the rotating shaft being connected to a bearing on the support frame, and a power unit connected to the rotating shaft; multiple rollers, each roller's lower surface abutting against the main conveyor belt; and a controller electrically connected to the identifier and the power unit. Each sub-conveyor belt corresponds to one address information, and the controller compares the package's address information with the address information corresponding to the sub-conveyor belt. When the two information match, the controller controls the power unit to operate. This intelligent sorting device avoids the risk of damage to the items inside packages caused by unreliable gripping or excessive clamping force when using clamps to grip packages.

The utility model discloses an anti -skidding sofa cover relates to furniture article technical field, and its technical scheme main points are: including cushion cover, the cushion cover includes a plurality of cushion cover module, and the junction of adjacent two cushion cover modules is equipped with flexible limiting sheet, is equipped with a plurality of friction strips on flexible limiting sheet, and the one end of flexible limiting sheet is fixed with plastic pole, and the bottom surface of cushion cover is equipped with a plurality of rubber bosses. When the tendency of relative movement of cushion cover and sofa occurs, flexible limiting sheet can play the better limiting effect to cushion cover module, in addition, rubber boss can also improve the friction between cushion cover module and sofa, reduce the number of people who need to arrange sofa cover after leaving sofa, when using flexible limiting sheet limiting cushion cover module, can through the hand of plastic pole and embed the end of flexible limiting sheet in sofa seam, and plastic pole is relatively hard to sofa, can conveniently embed flexible limiting sheet in sofa seam.
