Abstract

The utility model discloses a fall-protection climbing device used for enabling the climbing operation on a cylindrical, conical or cylinder-like-shaped structural body based on a simple and ingenious mechanical structure and suitable for being applied to the installation, detection and maintenance of a building/engineering equipment of a cylindrical or cylinder-like-shaped structure. According to the technical scheme of the utility model, based on the basic principle of a clinohedral, the inner conical surface of a cone is provided with uniformly distributed grooves and rolling balls are arranged in the grooves. Through the skillful application of the difference between the diameters of a cone and a cylinder, when the cone moves downwards relative to the cylinder, the rolling balls are driven to move upwards relative to the cone under the action of the frictional force so as to tightly clamp the cylinder. When the clinohedral moves upwards relative to the cylinder, the rolling balls are driven to move downwards relative to the cone under the action of a restoring spring so as to loosen the cylinder. In this way, due to the adoption of the above purely mechanical structure, the climbing operation is stable, reliable and high in safety, while the falling is prevented at the same time. Meanwhile, the fall-protection climbing device of an opening and closing mechanism also has the advantages of convenient operation and strong adaptability in working condition.

The specific embodiment

In order more clearly to set forth architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.

Referring to Figure 11, operation principle of the present utility model is: each conical structure body passes a cylinder up and down, the inner conical surface of conical structure is provided with uniform groove, be placed with the ball of some in the groove, ball contacts with cylinder under the effect of spring, certain precompression is arranged, when cone moves downward with respect to cylinder, ball moves upward with respect to circular cone under the effect of frictional force, because more up the diameter of section of circular cone diminishes, and the diameter of cylinder is constant, thereby ball clamps cylinder, in the process that clamps, certain deformation appears in first ball, and deflection is often very little, make second ball also contact with cylinder, and certain deformation also appears, and the like, constantly there is ball to contact with cylinder, correspondingly, the frictional force that is subjected to along with the increase cylinder that is out of shape also constantly increases, and is static relatively with respect to cylinder until cone, realized self-locking and fall arrest thus; The utility model realize cone with cylindrical relative static be not frictionally, but brake by the difference realization of inner conical surface and body diameter.

When cone moves upward with respect to cylinder, along with the change of the difference of inner conical surface diameter and column diameter is big, the deflection of ball to alleviating and slowly eliminate, thereby make relative motion smooth and easy.

In this preferred embodiment, mainly be divided into climbing mechanism and following climbing mechanism, the action of climbing is as follows: (1) fixing climbing device down, (2) will go up the climbing device certain altitude that moves up, (3) the fixing climbing device of going up, (4) will descend the climbing device certain altitude that moves up, and so forth, just can realize whole climbing action.
