Description

Clamp of rope tensile detection mechanism

Technical Field

The invention relates to a detection device, in particular to a clamp of a rope tensile detection mechanism.

Background

At present, the detection mechanism at home and abroad basically adopts a knot at one end of the rope for tensile detection, and stretches the rope after a hook or other workpieces pass through the knot to realize tensile detection of the rope, so that the rope is required to be knotted every time the detection is carried out, and the time is consumed, and meanwhile, the rope is wasted. At present, the rope is directly held at one end of the rope, when the detected tension is large, the holding force of the rope needs to be large, meanwhile, the rope is damaged to a certain extent, the actual detection tensile strength is error to a certain extent, and when the holding force is insufficient, the rope is easy to slip.

The clamp of the rope tensile detection mechanism can achieve artificial control by extruding the extrusion inner die and the extrusion outer die and simultaneously generating extrusion force through compression of the gas spring; the extrusion path of the rope is longer, and the rope is distributed in a circular shape, so that the extrusion is uniform, and the rope is not easy to slip. Meanwhile, the rope can not be damaged, the detection effect is good, and the detected data is close to the actual data.

Detailed Description

As shown in fig. 1 to 3, a fixture for a rope tensile detection mechanism according to an embodiment of the present invention includes: 2 rails 1 are horizontally and fixedly arranged in parallel front and back, and grooves are formed in the inner side of the rails 1; the positioning plate 3 is fixedly arranged above the track 1 through bolts, and the positioning plate 3 is wedge-shaped; the two sides of the bottom plate 4 are fixedly provided with the sliding blocks 2 through bolts, the sliding blocks 2 are matched with the grooves in size, the bottom plate 4 is arranged in the middle of the track 1 through the sliding blocks 2, and two working slide ways 10 are processed on the bottom plate 4 along the front-back direction; the extrusion internal mold 11 is arranged in the middle of the bottom plate 4; the extrusion outer die 8 is 2 blocks and is symmetrically arranged on the bottom plate 4 front and back; the working plate 5 is 2, through gas spring 7 and extrusion external mold 8 swing joint, the below of working plate 5 passes through bolt fastening work slider 6, and work slider 6 matches with work slide 10, and work slide 10 is the dovetail structure, and work slider 6 is the dovetail structure. A pull rod 9 is arranged on the left side of the bottom plate 4. The working plate 5 is of a wedge-shaped structure and is matched with the positioning plate 3. The opposite sides of the extrusion outer die 8 and the extrusion inner die 11 are curved (see fig. 3). The center of the extrusion die 11 is circular.

The extrusion rope of the extrusion inner die and the extrusion outer die is adopted, meanwhile, extrusion force is generated through compression of the gas spring, artificial control can be achieved, damage to the rope can be avoided, the detection effect is good, and detected data are close to actual data. The extrusion route of the rope is longer, and the rope is distributed in a round shape, so that the extrusion is even, and the rope is not easy to slip. The bolt positioning of the extrusion internal mold and the movable connection of the extrusion external mold make the replacement very convenient, and the universality of the clamp is improved.

When in specific use, the invention is described with reference to the drawings for convenient understanding;

the rope 12 is threaded to a gap between the extrusion inner die and the extrusion outer die along the arrow in fig. 1, the pull rod moves leftwards through the hydraulic mechanism, and the bottom plate moves leftwards horizontally under the action of the pull rod due to the fact that the sliding block is arranged at the inner side groove of the track; the working plate moves linearly along the working slide way of the bottom plate through the working slide blocks below, when the working plate contacts with the positioning block, the working plate is firstly contacted with the inclined plane, the side thrust of the inclined plane pushes the working plate to the middle, and the working plate pushes the extrusion outer die to move to the middle through the gas spring until the rope is fixed between the extrusion inner die and the extrusion outer die until the inclined plane contacts; when the working plate is in plane contact with the positioning block, the working plate is static relative to the bottom plate, namely, the extrusion inner die and the extrusion outer die are static, the extrusion of the rope is generated by the elastic force generated by the elastic deformation of the gas spring and is a fixed value, different extrusion forces can be generated by changing the gas spring, so that the rope cannot slip, and the tensile strength of the rope can be detected by increasing the tensile force of the pull rod. After the detection is finished, the pull rod moves to the right to reset.
