Description

Simple steel wire rope hook tensile test device

Technical Field

The utility model relates to an intensity detects the field, especially relates to a simple and easy wire rope gib head tensile test device.

Background

According to the seventh provision of clause 461 of the coal mine safety code, the steel wire rope connecting device for inclined roadway transportation needs to be tested by a tensile force 2 times of the maximum static load when the steel wire rope is replaced. The existing equipment structure is generally complex, and the problems that the detection period is long, the detection cost is high, the underground production needs cannot be timely met and the like exist. However, the underground operation steel wire rope is frequently replaced, and how to make the detection work of the steel wire rope on the premise of ensuring the accuracy and reliability of the detection effect and saving the detection time and the detection cost becomes a new subject before people.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art weak point, provide a simple and easy wire rope gib head tensile test device of simple structure, reliable and stable, a simple and easy wire rope gib head tensile test device include the portal frame, the portal frame is the square frame form.

The top of the portal frame is provided with a chain block, and the chain block is a chain block in the prior art. And the lifting hook of the inverted chain is connected with the wireless electronic lifting hook scale.

The portal frame is characterized in that a steel rope fixing device is installed at the bottom of the portal frame and comprises a bottom frame, the bottom frame is in a frame form, and a steel rope penetrating boss is arranged in the middle of the top surface of the bottom frame. The wire steel rope penetrates through the boss, a penetrating hole is formed in the middle of the boss, the penetrating hole is wide in the upper portion and narrow in the lower portion, and the penetrating hole penetrates through the upper top face of the underframe.

The electronic hook scale is connected with the steel ropes in a hook mode, the steel ropes are bent through wire harnesses to form hook heads, the wire harnesses are in a square tube mode, the inner diameters of the wire harnesses are attached to the double-strand steel ropes, screw holes are formed in the side walls of the wire harnesses, bolts are arranged in the screw holes in a threaded mode, the steel ropes are bent to penetrate through the wire harnesses, and the bolts are tightened to enable the two steel ropes to be fixed in a hard limiting mode. The other end of the steel rope penetrates through the penetrating hole and is knotted at the tail part, so that the steel rope is prevented from falling out of the penetrating hole during testing.

And a signal processor is arranged on the side edge of the portal frame and is in signal connection with the electronic hook scale.

The utility model has the advantages that: the utility model discloses simple structure, convenient to use, low in cost and easy to maintain have realized the tensile accurate test of steel cable gib head through simple structure, compare with prior art, and test effect is more directly perceived, and the test flow is more simple and convenient.

Detailed Description

Referring to fig. 1, fig. 2 and fig. 3, the utility model discloses a simple and easy wire rope gib head tensile test device, including portal frame 2, portal frame 2 is the square frame form.

The top of the portal frame 2 is provided with a chain block 1, and the chain block 1 is a chain block in the prior art. And the lifting hook of the chain block 1 is connected with a wireless electronic lifting hook scale 7.

The bottom of the portal frame 2 is provided with a steel rope 6 fixing device, the steel rope 6 fixing device comprises an underframe 4, the underframe 4 is in a frame form, and a steel rope penetrating boss 5 is arranged in the middle of the top surface of the underframe 4. The wire steel rope penetrating boss 5 is centrally provided with a penetrating hole, the penetrating hole is wide at the top and narrow at the bottom, and the penetrating hole penetrates through the upper top surface of the underframe 4.

The electronic hook scale 7 is connected with the steel ropes 6 in a hook mode, the steel ropes 6 are bent through the wire harnesses 3 to form hook heads, the wire harnesses 3 are in a square tube mode, the inner diameter of the wire harnesses is attached to the double-strand steel ropes 6, screw holes are formed in the side walls of the wire harnesses 3, bolts are arranged in the screw holes in a threaded mode, the steel ropes 6 are bent to penetrate through the wire harnesses 3, and the bolts are tightened to enable the two steel ropes 6 to be fixed in a hard limiting mode. The other end of the steel rope 6 penetrates through the penetrating hole and is knotted at the tail part, so that the steel rope is prevented from falling out of the penetrating hole during testing.

And a signal processor 8 is arranged on the side edge of the portal frame 2, and the signal processor 8 is in signal connection with the electronic hook scale 7.

The utility model discloses during the use, pass the hole of wearing with 6 one end of steel cable to knot at the afterbody, deviate from the hole of wearing during the test. The other end is bent to penetrate through the wire harness 3, and the bolt is tightened to enable the two steel ropes 6 to be fixed in a hard limiting mode. Through the pulling of chain block 1, wireless electron lifting hook balance 7 transmits pulling force data to signal processor 8 in real time, and signal processor 8 display screen shows the pulling force, carries out real-time detection.
