A pick-shaped pick capable of measuring cutting temperature

Abstract

A pick-type pick capable of measuring cutting temperature, including an alloy head and a pick tooth body, the alloy head is installed on the top of the pick tooth body, and also includes an embedded miniature thermal sensor, a data acquisition base and a data storage module The embedded miniature thermal sensor and the data acquisition base are arranged inside the alloy head, the data storage module is located in the lower cavity of the pick tooth body, and the embedded miniature thermal sensor is connected to the data storage module through the data acquisition base. The present invention has the advantages of simple structure, accurate measurement, etc., and gathers functions such as collection, storage, and power supply inside the pick-shaped pick, which ensures the flexibility of pick movement and improves the accuracy of temperature measurement inside the pick alloy head. Obtain the real-time internal temperature of the pick-shaped pick during the working process, and grasp the internal temperature change law of the pick-shaped pick under different working conditions, which provides an important basis for improving the safety of mining operations and prolonging the service life of the pick-shaped pick. Strong innovation and wide practicability.

Description

technical field [0001] The invention relates to a pick-shaped pick capable of measuring cutting temperature, which is suitable for measuring the cutting temperature of coal cutting equipment such as coal shearers and tunneling machines. Background technique [0002] Coal is the main energy source in our country. Coal rock cutting equipment such as shearers and roadheaders have greatly improved the efficiency of coal mining. However, the friction between the pick and the coal rock during the mining process causes the temperature of the pick to rise sharply, seriously affecting The service life of the pick is shortened, resulting in a great consumption of the pick in the coal mining operation. In order to prolong the service life of the pick pick, it is necessary to obtain the temperature change process of the pick under working conditions. To measure the temperature of pick-shaped picks, most of them use thin film patches or infrared monitoring methods. Only the surface temp...

Problems solved by technology

[0004] However, in the above-mentioned prior art, the temperature measurement unit is located inside the pick, while the data acquisition, data storage and power supply units are located outside the pick, and are connected by data lines, which cannot meet the requirements of the rotation during the cutting process of the pick pick. Advancement and self-rotating movement greatly reduce the flexibility of the pick-shaped pick, and the real measurement results cannot be obtained; the additional data acquisition, data storage and power supply unit occupy a certain space, which will inevitably affect the overall cutting effect; the cutting process During the process, coal and rock particles continuously impact and rub the external components, damage the external components, and in severe cases, damage the data lines and external components; at the same time, the dust and dust spray during the cutting process will cause short circuits of the external components and burn out the measurement circuit and components
