[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0029] like Figure 1-8As shown, the utility model provides a tungsten wire rope pre-stretching test fixture, including a stretching fixture base 1 and a ball head clamp 2, the stretching fixture base 1 includes a base fixing end 11 and a ball head connecting end 12, the base fixing end 11 is used to be fixed on an external carrier, the ball head connecting end 12 is provided with a fixture mounting groove 121 which runs transversely through and can be installed with the ball head clamp 2, and a fixture mounting hole 122 is provided at the bottom center of the fixture mounting groove 121, and a first side cutout 123 is provided on the side wall of the ball head connecting end on one side of the fixture mounting hole 122; the ball head clamp 2 is in the shape of a truncated cone, a through hole 23 allowing the tungsten wire rope to pass through is opened in the center of the truncated cone, and an inwardly concave ball head fixing groove 24 is provided on the end face of the thick-diameter end 22, and a second side cutout 25 which penetrates the side surface is provided on one side of the ball head fixing groove 24 and the through hole. The functions of the first side incision 123 and the second side incision 25 are both for the tungsten wire rope to pass through. The tungsten wire rope 3 enters the fixture mounting hole 122 through the first side incision 123, and then enters the through hole 23 of the ball head fixture 2 through the second side incision 25; the actual operation sequence is to first install the tungsten wire rope with the ball head structure into the ball head fixture 2, at which time the tungsten wire rope first passes through the second side incision 25 to enter the through hole 23, and then pull the tungsten wire rope backward to make the ball head structure 31 enter the ball head fixing groove 24, and then install the ball head fixture 2 with the tungsten wire rope 3 into the fixture mounting groove 121 of the stretching tooling base 1, at which time the tungsten wire rope at the rear end of the ball head fixture 2 passes through the first side incision 123 to enter the fixture mounting hole 122, and then continue to pull the tungsten wire rope backward to make the thin diameter end 21 of the ball head fixture 2 enter the fixture mounting hole 122, thereby realizing the fixation of the ball head fixture 2 in the stretching tooling base 1. When fixing, it is best to rotate the ball head clamp 2 by a certain angle so that the first side cutout 123 and the second side cutout 25 are staggered, so that the tungsten wire rope will not slip out of the ball head clamp 2 and the stretching tooling base 1 even when the tungsten wire rope is not tightened.
[0030] The width of the first side cutout 123 is equal to the diameter of the tungsten wire rope 3 , and the first side cutout 123 is connected to the fixture installation hole 122 .
[0031] The diameter of the fixture mounting hole 122 is larger than the diameters of the tungsten wire rope 3 and the ball head structure 31 .
[0032] The ball head fixing groove 24 is hemispherical so as to be compatible with the ball head structure 31 .
[0033] The diameter of the ball head fixing groove 24 is greater than the diameter of the tungsten wire rope, so that the ball head fixing groove 24 can fix the ball head structure 31 .
[0034] The width of the second side cutout 25 is equal to the diameter of the tungsten wire rope, so that the tungsten wire rope 3 can enter the through hole 23 from the second side cutout 25 .
[0035] The diameter of the small diameter end 21 of the truncated cone is equal to the diameter of the fixture installation hole 122 , and the diameter of the large diameter end 22 is larger than the diameter of the fixture installation hole 122 .
[0036] The length of the fixture installation slot 121 is greater than the height of the ball head fixture 2 so that the ball head fixture 2 can be installed in the fixture installation hole 122 .
[0037] The base fixed end 11 is provided with a connection structure, which is a ring stage 111 arranged in an annular shape, and a threaded connection structure 112 is also provided at the end. The ring stage 111 can play a role of limiting, and is used to be clamped in the notch of the channel steel for fixing; the threaded connection structure 112 can be fixedly connected with the threaded hole of the external component (with the auxiliary connection nut structure for fixing), so that fixation can also be achieved. The connection structure can also be a connection structure of other shapes and structures, so that the base fixed end 11 can be fixed.
[0038] The tungsten wire rope pre-tensioning test fixing tool provided by the utility model fixes the rope end of the tungsten wire rope with a ball head structure, so that the tungsten wire rope at one end of the ball head structure can be kept fixed during the tensile test, ensuring the tensile test to be carried out.
[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
