Novel tubular conveyer belt rebound force measuring device and measuring method thereof

Abstract

The invention discloses a novel tubular conveyer belt rebound force measuring device and a measuring method thereof. The device comprises a chuck shell and a bevel gear disc coaxially arranged in thechuck shell. A planar threaded groove is formed in the upper end surface of the bevel gear disc. A plurality of clamping grooves of the same structure are symmetrically formed in the radial directionof the chuck shell. A clamping jaw of the same structure is arranged in each clamping groove. Each clamping jaw is limited in the corresponding clamping groove and can slide in the clamping groove. Aplurality of pin shafts meshed with the planar threaded groove are distributed on the lower sides of the clamping jaws at equal intervals. When the bevel gear rotates, the clamping jaws are pushed bythe planar threaded groove to synchronously move towards the center / outer peripheral direction of the chuck shell along the tracks of the clamping grooves. In this way, the size of the circumference of each clamping jaw can be changed. The invention has the advantages of simple and feasible technical means, light and portable size, low manufacturing cost, simple and convenient operation during themeasurement process, and high measurement precision. The device and the method provide positive and effective application data for the model selection of circular and tubular conveyer belts.

Description

Technical field [0001] The present invention relates to rubber rebound force measurement, in particular to a new type of tube conveyor belt rebound force measurement device and measurement method. Background technique [0002] Tubular conveyor belt is a kind of closed conveyor belt, which can reduce material leakage during transportation, avoid environmental pollution, and prevent material pollution and deterioration. The tube-shaped conveyor belt can also realize the change of direction transportation in space, and has been widely used in recent years. However, if the rebound force of the tubular conveyor belt is not selected properly, it will damage the rollers and other components and affect the transportation effect. Therefore, the rebound force of the conveyor belt must be measured so that the force of the roller is in the normal working range. [0003] At present, the measuring device of the tubular conveyor belt is mainly vertical. This measuring method makes the sample of...

Problems solved by technology

[0003] At present, the measuring device of the tubular conveyor belt is mainly vertical. This measurement method places the sample of the circular tubular conveyor belt horizontally, and the measured rebound force will introduce the gravity interference of the conveyor belt itself, making the measurement result inaccurate.

Although some measuring devices can simulate the working conditions of the conveyor belt, they occupy a large area and are difficult to move, making it inconvenient to measure on the industrial site
