DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1-Figure 7 As shown, a wire rope tensile strength detection device provided by an embodiment of the present invention includes a base 101, a vertical plate 102 is fixedly provided on the upper surface of the base 101, and a lower mounting block 103 is fixedly provided on the top of the vertical plate 102, a hydraulic telescopic cylinder 104 is also fixedly provided on the upper surface of the base 101, and a top plate 105 is fixedly provided at the telescopic end of the hydraulic telescopic cylinder 104, a movable plate 108 is movably provided through the outer wall of the top plate 105, a movable plate 106 is fixedly provided on the top of the movable plate 108, and an upper mounting block 109 is fixedly provided on the bottom end of the movable plate 108, a pressure sensor 107 is fixedly provided on the lower surface of the movable plate 106, and the pressure sensor 107 is located at the movable plate 108. Between the plate 106 and the top plate 105, the outer walls of the upper mounting block 109 and the lower mounting block 103 are both provided with a tapered opening 110, and a tapered member 111 is movably provided in the tapered opening 110, a through hole 112 is provided at the bottom end of the tapered member 111, and a spiral groove 113 is provided on the outer side of the tapered member 111. It also includes: a connecting component, which is arranged on the outer side of the tapered member 111, and is used to limit the tapered member 111 in the tapered opening 110, and when the tapered member 111 moves out of the tapered opening 110 under the action of an external force and resets it to the tapered opening 110 after the external force disappears; a protective component, which is arranged between the base 101 and the top plate 105, and is used to protect the wire rope when it is detected.

[0027] The two ends of the steel wire rope to be tested can be fixed in the lower mounting block 103 and the upper mounting block 109 respectively. When fixing, the end of the steel wire rope is mainly passed through the through hole 112 on the tapered member 111, and then the tapered member 111 is pushed to make the tapered member 111 move out of the tapered mouth 110. When the tapered member 111 moves out of the tapered mouth 110, the steel wire rope passing through the tapered member 111 can be wound around the spiral groove 113 on the outside of the tapered member 111, and then the tapered member 111 is loosened. When the connection assembly is reset, the conical member 111 can be moved back into the conical opening 110, and the wire rope in the spiral groove 113 can be clamped between the conical opening 110 and the spiral groove 113. When the tensile strength of the wire rope is tested, the top plate 105 can be driven upward by the hydraulic telescopic cylinder 104, so that the movable plate 106 moves upward synchronously, and the upper mounting block 109 and the movable plate 106 are connected by the movable plate 108, so that the upper mounting block 109 moves upward together. When the wire rope is pulled upward, the movable plate 106 exerts downward pressure on the pressure sensor 107 until the wire rope is broken. When the wire rope is broken, the maximum value detected by the pressure sensor 107 is recorded, and the tensile strength of the wire rope can be detected. In the process of pulling the wire rope, since the end of the wire rope is wound around the spiral groove 113, the wire rope will exert a certain pulling force on the conical member 111. When the tension on the wire rope gradually increases, the pressure applied by the conical member 111 to the conical mouth 110 will also gradually increase, so that the clamping force of the wire rope end is proportional to the tension on the wire rope, thereby effectively avoiding the slippage of the wire rope end, which makes it impossible to detect. In the detection process, the protective component can also play a certain protective role. When the wire rope is broken, the wire rope can be blocked, which further improves the safety of the detection process and has a better use effect.

A telescopic rod 206 is movably arranged through the outer wall of the plug plate 203. A slider 207 is fixedly arranged on the top of the telescopic rod 206, and a baffle 204 is fixedly arranged on the bottom end of the telescopic rod 206. The outer walls of the upper mounting block 109 and the lower mounting block 103 are provided with equidistant and annular sliding grooves 208, and the cross-section of the sliding groove 208 is convex. The slider 207 is slidably arranged in the sliding groove 208. A spring 205 is also sleeved on the outer side of the telescopic rod 206. One end of the spring 205 and the plug plate The outer wall of the cone 111 is connected to the outer wall of the cone 203, and the other end of the spring 205 is connected to the outer wall of the baffle 204. When the cone 111 moves out of the cone mouth 110 under the action of external force, the cone 111 will drive the mounting frame 201 to move, and the mounting frame 201 drives the plugging plate 203 to move outside the telescopic rod 206, so that the spring 205 is stretched. When the external force disappears, the cone 111 can be moved back into the cone mouth 110 under the resetting action of the spring 205, and when the limiting bolt 202 is removed, the plugging plate 203 can be taken out from the slot on one side of the mounting frame 201. At this time, the slider 207 can also be slid out of the slide groove 208, so that the limiting of the cone 111 can be released, which is convenient for cleaning and maintenance of the cone 111 and more convenient to use.

When the tensile strength of the wire rope is tested, the top plate 105 can be driven upward by the hydraulic telescopic cylinder 104, so that the movable plate 106 moves upward synchronously, and the upper mounting block 109 and the movable plate 106 are connected through the movable plate 108, so that the upper mounting block 109 is When the wire rope is pulled upward, the movable plate 106 applies downward pressure to the pressure sensor 107 until the wire rope is broken. When the wire rope is broken, the maximum value detected by the pressure sensor 107 is recorded to detect the tensile strength of the wire rope. In the process of pulling the wire rope, since the end of the wire rope is wound in the spiral groove 113, the wire rope will exert a certain pulling force on the conical member 111. When the tension on the wire rope gradually increases, the pressure applied by the conical member 111 to the conical mouth 110 will also gradually increase, so that the clamping force of the wire rope end is proportional to the tension on the wire rope, thereby effectively avoiding the slippage of the wire rope end, which makes it impossible to detect. In the detection process, the protective component can also play a certain protective role. When the wire rope is broken, the wire rope can be blocked, which further improves the safety of the detection process and has a better use effect.
