Description

Technical Field

[0001] The utility model relates to a temperature measuring device for the bottom of a cargo box, belonging to the technical field of mine cars. Background Art

[0002] In order to measure the heating effect of the engine exhaust on the cargo box of the mine car, it is necessary to collect data on the temperature changes over time at different positions at the bottom of the cargo box. The sensor commonly used to collect temperature at present is a thermocouple, and thermocouples are divided into welding point type and armored type. Among them, the welding point type thermocouple is suitable for measuring non-contact air radiation temperature due to the small measuring probe area, while the armored thermocouple is a secondary packaging of the welding point type thermocouple, which increases the measuring probe area and is designed with a fixed thread for easy installation, making it suitable for contact temperature measurement. Since the temperature at the bottom of the cargo box of the mine car needs to be measured using a contact method, an armored thermocouple sensor is selected for measurement, but the armored thermocouple lacks a fixed tooling, so the utility model designs a temperature measuring device for the bottom of the cargo box of the mine car.

[0029] like Figure 1As shown, a temperature measuring device for the bottom of a cargo box includes a connecting component with a accommodating cavity, a fixing component and a locking component; the connecting component is used to install the probe of the armored thermocouple 1; one end of the fixing component is fixed to the bottom of the cargo box, and the other end is inserted into the accommodating cavity of the connecting component, and the size of the accommodating cavity of the connecting component is adjusted by the depth of the insertion, thereby adapting to the probes of the armored thermocouple 1 of different lengths; the locking component fixes the connecting component to the fixing component to prevent the connection length between the two from changing, which causes the top of the probe of the armored thermocouple 1 to not be firmly attached to the bottom of the fixing component.

[0030] The above-mentioned connecting components are further described below.

[0031] Continue to refer to Figure 1 As shown, the connecting component is a threaded sleeve 2; the probe of the armored thermocouple 1 has an external thread, and the probe of the armored thermocouple 1 is screwed into the threaded sleeve 2 through the cooperation of the internal and external threads until the front end face of the probe is against the fixed component extending into the accommodating cavity.

[0032] The above-mentioned fixing components are further described below.

[0033] Continue to refer to Figure 1 As shown, the connecting component is a threaded sleeve 2; the fixing component is a fixing tube 4 with an external thread in the top area. The fixing tube 4 is screwed into the threaded sleeve 2 through the cooperation of the internal and external threads, and the size of the accommodating cavity is adjusted by the depth of screwing.

[0034] For further solutions, please refer to Figure 1 As shown, the fixing tube 4 has at least two welding bases 42, evenly spaced along the entire circumference, on its outer circumferential surface at the end portion outside the threaded sleeve 2 for welding to the cargo box bottom. These welding bases 42 weld the entire temperature measuring device to the cargo box bottom, preventing it from falling off during vehicle operation.

[0035] For further solutions, please refer to Figure 1 As shown, the fixing tube 4 is provided with at least one wire lug 41 on its outer circumferential surface, located outside the threaded sleeve 2, for passing and securing the wire harness of the armored thermocouple 1. When multiple temperature measurement points are arranged at the cargo box bottom, multiple such temperature measurement devices are required. In this case, the wire harness of the armored thermocouple 1 at the rear can be passed through the wire lug 41 of the front measurement device to prevent the wire harness from being melted by the high-temperature surface of the cargo box bottom or being torn off by moving parts.

[0036] The above-mentioned locking component is further described below.

[0037] Continue to refer to Figure 1As shown, the connecting component is a threaded sleeve 2; the locking component is a locking bolt 3, and the outer circumferential surface of the threaded sleeve 2 is provided with at least one threaded hole extending radially inward and connected to the accommodating cavity, and the locking bolt 3 is screwed into the threaded hole until it is tightened on the fixing tube 4.

[0038] For further solutions, please refer to Figure 1 As shown, the locking bolt 3 is a bolt with a hand wheel.

[0039] For further solutions, please refer to Figure 1 As shown, the probe, threaded sleeve 2 and fixing tube 4 of the armored thermocouple 1 are assembled together in a coaxial manner.

[0040] In summary, the temperature measuring device provided by the present invention is easy and reliable to install. The temperature measuring device is welded to the bottom of the cargo box by welding and will not fall off during the operation of the vehicle. The connection length of the threaded sleeve and the fixed tube can be adjusted to adapt to probes of armored thermocouples of various models and different lengths. The threaded sleeve and the fixed tube are further locked by the locking bolt to prevent the connection length between the two from changing, which causes the top of the armored thermocouple probe to be unable to be firmly attached to the bottom of the fixed tube. The wire hanging ear is convenient for fixing and arranging the wiring harness and prevents the wiring harness from being broken by the high-temperature melting surface of the bottom of the cargo box or being torn off by moving parts. The temperature measuring device can also reduce the influence of the external environment on the measurement results of the armored thermocouple and avoid irreversible damage to the cargo box caused by opening a hole in the bottom of the cargo box and inserting the armored thermocouple probe for measurement.
