Description

Technical Field

[0001] This utility model belongs to the technical field of pulley testing devices, specifically relating to a polyethylene wire pulley testing device. Background Technology

[0002] Polyethylene conductors, also known as PE conductors, are wires made of polyethylene (PE). These conductors have wide applications in many fields, mainly due to the unique properties of polyethylene. Polyethylene conductors are typically wound around the surface of pulleys for storage, and these pulleys need to be tested using testing equipment during the manufacturing process.

[0003] Existing pulley testing machines typically test pulleys by clamping and fixing them to the inside of a lifting rod. Since the clamping mechanism of this lifting rod is fixed, it can only clamp and test pulleys of a single size and cannot clamp and fix pulleys of different specifications, which leads to inconvenience in use. To address this, we propose a polyethylene wire pulley testing device. Utility Model Content

[0004] The purpose of this utility model is to provide a polyethylene wire pulley testing device to solve the problem that the clamping mechanism of the pulley testing device mentioned in the background art is inconvenient to use.

The adjustable clamping mechanism includes: a clamping component disposed at the bottom of the lifting rod; a reset component disposed inside the clamping component; and a locking component disposed at the bottom of the clamping component.

[0006] Preferably, the clamping assembly includes a fixed base fixed to the bottom end of the lifting rod and a through slot opened through one side of the fixed base, and a clamping rod is provided inside the through slot.

[0007] Preferably, one end of the clamping rod has a limiting groove, which engages with the end of the pulley.

[0008] Preferably, the reset assembly includes a sliding groove extending through the surface of the clamping rod and a sliding block disposed inside the through groove, wherein a telescopic spring is connected between the sliding block and the sliding groove.

[0009] Preferably, the locking assembly includes a locking hole extending through the bottom of the inner wall of the through groove and a locking rod disposed at the bottom of the fixed base and screwed into the locking hole.

[0010] Preferably, a pull button is fixed to the other end of the clamping rod.

[0011] Preferably, the cable fixing mechanism includes cable holders fixed at equal intervals on one side of the base and rubber buckles symmetrically fixed inside the cable holders, and the power connection cable is engaged with the cable holders.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through its designed fixed base, through groove, clamping rod, limiting groove, sliding groove, sliding block, and telescopic spring, can clamp and limit pulleys of different sizes. In addition, with the designed locking hole and locking rod, the clamping rod in the limiting position can be locked and positioned.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3This utility model provides a technical solution: a polyethylene wire pulley testing device, including a base 1, a support frame 2 fixed to the top of the base 1, a lifting rod 3 extending through the top of the support frame 2, a test wheel 4 extending to the top of the base 1 inside the base 1, a pulley 5 on the inner side of the lifting rod 3, a power connection cable 6 fixedly connected to one side of the base 1, an adjustable clamping mechanism at the bottom of the lifting rod 3, and a wire fixing mechanism fixed to one side of the base 1. The adjustable clamping mechanism includes: a clamping component at the bottom of the lifting rod 3; a reset component inside the clamping component; and a locking component at the bottom of the clamping component.

[0020] In this embodiment, preferably, the clamping assembly includes a fixed base 100 fixed to the bottom end of the lifting rod 3 and a through groove 101 through one side of the fixed base 100. A clamping rod 102 is provided inside the through groove 101, which can clamp and limit the pulley 5.

[0021] In this embodiment, preferably, a limiting groove 200 is provided at one end of the clamping rod 102, and the limiting groove 200 is engaged with the end of the pulley 5.

[0022] In this embodiment, preferably, the reset component includes a sliding groove 300 extending through the surface of the clamping rod 102 and a sliding block 301 disposed inside the through groove 101. A telescopic spring 302 is connected between the sliding block 301 and the sliding groove 300 to facilitate the reset movement of the clamping rod 102.

[0023] In this embodiment, preferably, the locking assembly includes a locking hole 400 that passes through the bottom of the inner wall of the through groove 101 and a locking rod 401 that is screwed into the locking hole 400 at the bottom of the fixed base 100, which can lock the clamping rod 102.

[0024] In this embodiment, preferably, the other end of the clamping rod 102 is fixed with a pull button 500 to facilitate pulling the clamping rod 102 to slide.

[0025] In this embodiment, preferably, the cable fixing mechanism includes cable holders 600 fixed at equal intervals on one side of the base 1 and rubber buckles 601 symmetrically fixed inside the cable holders 600. The power connection cable 6 is snapped into the cable holders 600, which can limit and store the power connection cable 6.

[0026] The working principle and usage process of this utility model are as follows: When it is necessary to perform clamping and limiting detection on the pulley 5, first loosen the locking rod 401 so that its end is screwed into the locking hole 400 and separated from the bottom end of the clamping rod 102, thus releasing the positioning of the clamping rod 102. Then, pull the clamping rod 102 through the pull button 500 to slide it inside the through groove 101, and drive the sliding groove 300 to slide on the surface of the sliding block 301, compressing the telescopic spring 302 to deform. Then, place the pulley 5 inside the fixed seat 100, and then release the pull button 500, so that the sliding groove 300 is compressed by the telescopic spring. Under the action of the spring 302, the sliding block 301 is reset and slids, while the clamping rod 102 is reset and moved inside the through groove 101, so that the limiting groove 200 is engaged with both ends of the pulley 5, which can temporarily limit the pulley 5. Then, tighten the locking rod 401 so that it rotates inside the locking hole 400 and presses against the clamping rod 102, which can clamp and fix the pulley 5 for testing. When it is necessary to fix the power connection cable 6, first insert the power connection cable 6 into the cable fixer 600 and limit it with the rubber buckle 601 to fix and store the power connection cable 6.
