Description
Technical Field
[0001] This utility model relates to rubber belt conveyor technology, specifically to a tear-resistant triggering device for conveyor belts. Background Technology
[0002] Rubber belt conveyors (also known as belt conveyors, belt conveyors or rubber belt conveyors) are an economical logistics conveying equipment widely used in various industries, mainly in mining, metallurgy, coal, light industry, electronics, food and other industries.
[0003] During long-term, high-intensity use, the conveyor belts of rubber belt conveyors are often damaged by wear, aging, or external factors, resulting in localized tears. If a tear in the conveyor belt is not detected in time, the tear area will expand rapidly. This will not only cause the conveyed items to fall out from the tear, resulting in material loss and environmental pollution, but may also cause irreversible damage to the overall structure of the conveyor belt, and even lead to equipment failure and production accidents. Utility Model Content
[0004] The purpose of this invention is to provide a tear-prevention triggering device for conveyor belts, in order to solve the problem that in the prior art, conveyor belts are prone to tearing and damage in some areas due to wear and tear during long-term use. Once a tear occurs in a part of the conveyor belt, if it is not detected in time, the torn area of the conveyor belt will tear further, causing the conveyed items to fall out of the torn area of the conveyor belt and leak out.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tear-resistant triggering device for a conveyor belt, comprising a mounting bracket, a trigger rope, a limiting device, and several guide components;
[0006] Several guide components are installed on the same side of the mounting bracket, and each guide component is provided with a through hole for the trigger rope to pass through.
[0007] One end of the trigger rope is connected to the limiting device, and the other end of the trigger rope passes through the through holes on multiple guides. The end of the trigger rope away from the limiting device is connected to the mounting bracket or a guide away from the limiting device, and the trigger rope is in a taut state.
[0008] Furthermore, the middle part of the mounting bracket is bent.
[0009] Furthermore, the end of the guide member furthest from the through hole is fixedly connected to the mounting bracket.
[0010] Furthermore, the mounting bracket has several threaded holes, each corresponding to a guide component. The end of the guide component away from the through hole is threadedly connected to the inner wall of a threaded hole near the guide component.
[0011] Furthermore, the mounting bracket is provided with two symmetrical inclined sections, and a horizontal section is provided between the two inclined sections. The two ends of the horizontal section are respectively connected to the bottom ends of the two inclined sections. Four guide members are provided. One end of two guide members is fixedly connected to the top side of the two inclined sections, and the other two guide members are provided at the two ends of the horizontal section. One end of the other two guide members is connected to the same moving drive mechanism, which is used to drive the other two guide members to move in opposite directions or in opposite directions along the length of the horizontal section.
[0012] Furthermore, the moving drive mechanism includes a screw and two sliders. One side of each slider is slidably connected to the side of the horizontal section. One end of each of the other two guide members is fixedly connected to the two sliders. The screw is provided with two sections of threads with opposite directions, and the screw is threadedly connected to the two sliders through the two sections of threads.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0028] Please see Figures 1 to 3 A tear-resistant triggering device for a conveyor belt includes a mounting bracket 1, a trigger rope 2, a limiting device 3, and several guide components 4.
[0029] Several guide members 4 are installed on the same side of the mounting bracket 1, and several guide members 4 are provided with through holes 5 for the trigger rope 2 to pass through;
[0030] One end of the trigger rope 2 is connected to the limiting device 3, and the other end of the trigger rope 2 passes through the through holes 5 on multiple guide members 4 respectively. The end of the trigger rope 2 away from the limiting device 3 is connected to the mounting bracket 1 or a guide member 4 away from the limiting device 3, and the trigger rope 2 is in a taut state.
[0031] Existing conveyor belts, when transporting items, are prone to tearing and damage in certain areas due to wear and tear from long-term use. If a tear occurs and is not detected in time, the torn area of the conveyor belt will further tear, causing the transported items to fall and leak out. To address this, this application installs a mounting bracket 1 at the bottom of the conveyor belt. When a tear occurs in the conveyor belt, the trigger rope 2 is taut. As the torn part of the conveyor belt droops or the items transported on the conveyor belt fall from the torn area, the trigger rope 2 is pushed. Since one end of the trigger rope 2 is fixed, when the trigger rope 2 is pushed, the other end of the trigger rope 2 moves and pulls the limiting device 3. The limiting device 3 controls the conveyor to stop, thereby preventing the conveyor belt from continuing to transport items even when it is torn, effectively preventing further tearing and damage to the conveyor belt and the leakage of transported items.
[0032] In one embodiment of this utility model, the guide member 4 is disposed on one side of the mounting bracket 1 in the width direction. When the mounting bracket 1 is at the same distance from the bottom of the conveyor belt, if the guide member 4 is disposed on the side of the mounting bracket 1 close to the bottom of the conveyor belt, the conveyor belt may be deformed by the conveyed items. Even if the deformation is small, the conveyor belt may directly contact the trigger rope 2, resulting in a certain false contact rate. However, when the guide member 4 is disposed on one side of the mounting bracket 1 in the width direction, the conveyor belt will not directly contact the trigger rope 2 when the deformation is small, thus reducing the false contact rate.
[0033] In one embodiment of this utility model, the middle part of the mounting bracket 1 is bent, and the mounting bracket 1 is installed at the bottom of the conveyor belt to adapt to the shape of the conveyor belt and avoid contact with the conveyor belt in normal condition.
[0034] In one embodiment of this utility model, the end of the guide member 4 away from the through hole 5 is fixedly connected to the mounting bracket 1. The guide member 4 can be welded to the mounting bracket 1 by welding. Several guide members 4 can be welded to the bend of the mounting bracket 1 so that the trigger rope 2 does not come into contact with the conveyor belt if the conveyor belt is not torn or damaged.
[0035] In one embodiment of this utility model, the mounting bracket 1 has a plurality of threaded holes, which correspond one-to-one with a plurality of guide members 4. The end of the guide member 4 away from the through hole 5 is threadedly connected to the inner wall of a threaded hole near the guide member 4, thereby facilitating the disassembly, installation and replacement of the guide member 4.
[0036] Please see Figures 4 to 5In one embodiment of this utility model, the mounting bracket 1 is provided with two symmetrical inclined sections, and a horizontal section is provided between the two inclined sections. The two ends of the horizontal section are respectively connected to the bottom ends of the two inclined sections. Four guide members 4 are provided, one end of two guide members 4 is fixedly connected to the top side of the two inclined sections, and the other two guide members 4 are provided at the two ends of the horizontal section to adapt to the existing V-shaped conveyor belt. One end of the other two guide members 4 is connected to the same moving drive mechanism 6. The moving drive mechanism 6 is used to drive the other two guide members 4 to move towards or in opposite directions along the length direction of the horizontal section.
[0037] Two guide members 4 are fixedly connected to the top of the inclined section of the mounting bracket 1. Since the bottom shape of different models of V-belts is different, and the bottom shape of the V-belt will also change when conveying items of different weights, the position of the guide members 4 connected to the horizontal section of the mounting bracket 1 can be driven by the moving drive mechanism 6 to adjust the trigger rope 2 so that the trigger rope 2 can fit the bottom shape of the V-belt better, thereby improving the trigger sensitivity of the device and improving the practicality of the device.
[0038] In one embodiment of this utility model, the moving drive mechanism 6 includes a screw 61 and two sliders 62. One side of each slider 62 is slidably connected to the side of the horizontal section. One end of each of the other two guide members 4 is fixedly connected to the two sliders 62. The screw 61 is provided with two threads with opposite directions. The screw 61 is threadedly connected to the two sliders 62 through the two threads. The outer wall of the middle part of the screw 61 is rotatably connected to the mounting bracket 1.
[0039] By rotating the screw 61, the screw 61 drives the two sliders 62 to move in opposite directions through the two sections of threads with opposite directions. When the sliders 62 move, they drive the guide members 4 connected to them to move, thereby changing the shape of the trigger rope 2. Furthermore, a rotary drive member, such as a motor or rotary cylinder, can be connected to the end of the screw 61 to drive its rotation. The position of the two guide members 4 connected to the horizontal section of the mounting bracket 1 can be adjusted in an automated control manner, thereby improving the automation level of the device.
[0040] Please see Figures 2 to 3In one embodiment of this utility model, the limiting device 3 includes a limiting switch 31, a trigger plate 32, and a connector. The limiting switch 31 is fixedly installed on the mounting bracket 1. One end of the trigger plate 32 is fixedly connected to the trigger rope 2. The trigger plate 32 is connected to the knob of the limiting switch 31 through the connector. The limiting switch 31 is existing technology. The limiting switch 31 adopts a knob-triggered switch. The knob-triggered switch is mainly composed of a metal ball, a spring, a knob, and a contact piece. Under normal circumstances, the metal ball is located within the contour of the spring, so that the spring and the contact piece are in the closed state, and the circuit is broken. When the knob is rotated, the metal ball, under the influence of centrifugal force, gradually slides away from the spring's contour, causing the spring to break and separate from the contact plate, thus closing the circuit and achieving the purpose of circuit switching. During the operation of the knob, the rotation of the knob changes the shape of the spring. At a certain pitch angle, the spring deforms, the metal ball is no longer constrained and slides off the spring, thereby opening the switch and opening the circuit. Usually, the knob and the spring are connected together by a contact plate. When the spring is stretched, the contact plate also springs open, opening the circuit. When the knob stops rotating, the spring is subjected to restoring force, pulling the contact plate back to its original position, closing the circuit.
[0041] The trigger plate 32 has a slide groove 33, and the connecting parts include a bolt 34. One end of the bolt 34 is fixedly connected to the knob of the limit switch 31, and the other end of the bolt 34 passes through the slide groove 33 and is threaded with a lock nut 35. The bolt 34 and the knob of the limit switch 31 are coaxially arranged.
[0042] The length of the end of the trigger rope 2 connected to the trigger plate 32 is opposite to the length of the trigger plate 32. Even when the end of the trigger rope 2 connected to the trigger plate 32 moves, the knob of the limit switch 31 can be rotated through the trigger plate 32 and the connector, thereby triggering the limit switch 31. After the limit switch 31 is triggered, the limit switch 31 controls the conveyor to stop, thereby preventing the conveyor belt from running even if it is torn at a certain point.
[0043] Furthermore, the position of the bolt 34 passing through the slide groove 33 can be adjusted to adjust the distance between the end of the trigger rope 2 and the knob of the limit switch 31. This allows the trigger rope 2 to move at different speeds to trigger the limit switch 31, adapting to the tearing triggering of the conveyor belt under different conveying environments, thus further improving the practical performance of the device.
[0044] In one embodiment of this utility model, the trigger rope 2 is made of steel wire rope, which extends the service life of the device and prevents the trigger rope 2 from wearing out and breaking under long-term use.
[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
