Description
Technical Field
The invention belongs to the technical field of detection equipment, and particularly relates to a roller noise detection chamber.
Background
The carrier roller is an important part of the belt conveyor, has multiple types and large quantity, and can support the weight of a conveying belt and materials. It accounts for 35% of the total cost of a belt conveyor and produces over 70% of the drag, so the quality of the idler is particularly important. There are two types of steel and plastic.
When the conveyer belt is carried, the factors that the bearing roller produced the noise mainly have following several: firstly, certain noise is generated due to the friction between the conveying belt and the carrier roller; secondly, the bearing inside the carrier roller is damaged to cause noise, and the performance level of the bearing is obviously reduced after the bearing runs for a long time, so that the bearing is easily damaged once being subjected to high pressure; thirdly, when the bearing runs, the bearing is easily influenced by the intervention of centrifugal force, and the normal running of the bearing is directly blocked, so that a series of noises are generated; fourthly, the abnormal noise is directly caused by the insufficient maintenance or the deviation of the roller. Therefore, noise is an important factor affecting the normal operation of the conveyor belt, and also affects the performance of the equipment. The noise is the real reaction of whether the conveyer belt runs normally. The carrier roller is installed outdoors, and noise cannot be directly detected. Therefore, a noise detection device capable of detecting the noise of the carrier roller in real time and further detecting whether the conveyor belt runs normally needs to be designed.
The invention content is as follows:
the technical problem to be solved by the invention is to provide a roller noise detection chamber which can isolate a roller from the outside and is convenient for detecting the noise of the roller.
The invention is realized by the following steps:
the utility model provides a bearing roller noise detection room, includes by the wall body, the wall body directly sets up subaerial or sets up on the bottom plate, is provided with the roof at the top of wall body and forms an outer cavity, is provided with the bearing roller holding cavity that is independent of outer cavity by inhaling that sound material encloses in outer cavity, is provided with the air chamber between outer cavity and the outer wall of inhaling the sound material, it is provided with the conveyer belt portion of running through that supplies to carry to send the area to pass through to inhale sound material, wall body on corresponding position, is provided with the noise detector in bearing roller holding cavity.
In the roller noise detection chamber, a muffler is provided at the conveyor belt penetration portion.
In the roller noise detection chamber, the wall body and the top plate are made of concrete materials.
In the roller noise detection chamber, the internal volume of the roller accommodating chamber is 3m × 3m × 3 m.
In the roller noise detection chamber, the background noise of the roller accommodating chamber is below 35 dB.
In the roller noise detection chamber, the thickness of the wall and the top plate is 200-300 mm.
In the roller noise detection chamber, the thickness of the sound absorbing material is 200-300 mm.
In the roller noise detection chamber, the thickness of the air cavity is 50-100 mm.
Compared with the prior art, the invention has the outstanding advantages that:
1. the carrier roller is isolated from the outside through the carrier roller noise detection chamber, so that the noise generated by the carrier roller in the working process can be accurately measured, and whether the conveying belt runs normally or not can be conveniently detected.
2. The invention has good sound insulation effect and high detection precision.
Description of the drawings:
