Technical Field

[0001] The utility model relates to the technical field of maintenance of mining belt conveyors, in particular to a test device for a temperature protection device of a belt conveyor. Background Technique

[0002] During the use of mining belt conveyors, affected by the air environment and the like, it is often necessary to control their temperature within a reasonable range. The Chinese utility model patent with the application number 202223384596.9 provides a test device for a temperature protection test box for a belt conveyor. This device can perform test operations at a certain distance from the monitoring probe through test pipelines and sensor lines. However, this device is not convenient to use: firstly, it is not convenient to carry and hold due to its large size; secondly, it is not convenient to deform and difficult to adapt to complex curved environments; finally, the number of test pipelines is small, and when warm water of multiple temperatures is poured in a short time, temperature conduction will occur and interfere, so it is difficult to conduct tests of multiple temperatures in a short time, making the test work time-consuming and laborious. This highlights the deficiencies of the prior art. Content of the Utility Model

[0003] The purpose of the utility model is to provide a test device for a temperature protection device of a belt conveyor to solve the above technical problems.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A test device for a temperature protection device of a belt conveyor includes a serpentine tube. A plurality of buckles are axially fixed on the outer wall of the serpentine tube. Each of the buckles commonly buckles a plurality of hoses. The hoses are arranged at intervals with each other. The hoses can move axially along the buckles. Each of the hoses is composed of a tube body and a heat insulation layer from the inside to the outside in sequence. The outer wall of the tube body is wrapped by the heat insulation layer. The rear ends of each of the hoses are respectively fixed with a hard downward-bent drain pipe, and the front ends of each of the hoses are respectively fixed with a hard upward-bent funnel. A downward-bent handle is fixed at the front end of the buckle on the outer wall of the serpentine tube that is the most forward.

[0006] On the basis of the above technical solution, a controller is fixed in the middle of the handle. The controller is electrically connected to a display screen, control buttons and a storage battery. A support frame is commonly fixed on the outer wall of the rear part of the serpentine tube and the outer walls of the hoses. A plurality of temperature sensors are fixed on the support frame. The probes of each of the temperature sensors are respectively inserted into the inner cavity of the hose. Each of the temperature sensors is electrically connected to the controller.

[0007] On the basis of the above technical solution, a plurality of mounting brackets are axially fixed on the serpentine tube. A plurality of rollers are rotatably connected to each of the mounting brackets at equal angular intervals around the serpentine tube as the axis.

[0008] Compared with the prior art, the utility model has the following advantages: by manually bending the serpentine tube and the hose, the utility model can shape the outer shapes of both, which not only facilitates carrying and holding, but also enables them to extend into complex and curved environments after shaping, improving the adaptability. Moreover, by using multiple separate hoses, drain pipes and funnels, temperature tests at multiple water temperatures can be carried out in a short time without interference with each other, saving more time and effort.

Detailed Description of the Embodiment

[0013] The following further elaborates on the utility model in detail in conjunction with the drawings and specific embodiments.

[0014] As Figures 1 - 3 shown, a test device for a temperature protection device of a belt conveyor includes a serpentine tube 1. Axially fixed on the outer wall of the serpentine tube 1 are a plurality of buckles 2. Each of the buckles 2 commonly buckles a plurality of hoses 3. The hoses 3 are arranged at intervals with each other. The hoses 3 can axially move along the buckles 2. Each of the hoses 3 is composed of a pipe body 4 and a heat insulation layer 5 from the inside to the outside in sequence. The outer wall of the pipe body 4 is wrapped by the heat insulation layer 5. Rigid downwardly bent drain pipes 6 are respectively fixed to the rear ends of each of the hoses 3. Rigid upwardly bent funnels 7 are respectively fixed to the front ends of each of the hoses 3. A downwardly bent handle 8 is fixed to the front end of the buckle 2 closest to the front on the outer wall of the serpentine tube 1.

[0015] During use, according to the use environment and as needed, manually bend the serpentine tube 1 and the hose 3 to shape the outer shapes of both by using the serpentine tube 1. Then, place the nozzle of the drain pipe 6 above the temperature detection probe of the temperature protection device to be tested. Then, pour water at different temperatures into different funnels 7 in sequence to pour and sprinkle the temperature detection probe of the target temperature protection device. According to whether the feedback result of the temperature detection probe of the temperature protection device is consistent with the water temperature, the test of the temperature protection device can be completed in a short time. The use of the heat insulation layer 5 can reduce the decrease of the water temperature to ensure the test accuracy.

[0016] A controller 9 is fixed in the middle of the handle 8. The controller 9 is electrically connected to a display screen 10, control buttons 11 and a storage battery 12. A support frame 13 is fixedly arranged on the outer wall of the rear part of the serpentine tube 1 and the outer walls of the hoses 3. A plurality of temperature sensors 14 are fixed on the support frame 13. The probes of the temperature sensors 14 are respectively inserted into the inner cavities of the hoses 3. The temperature sensors 14 are respectively electrically connected to the controller 9.

[0017] Furthermore, the temperature sensor 14 can measure the water temperature of the water about to be discharged from the drain pipe 6, and display the data result through the display screen 10. During this period, whether the corresponding temperature sensor 14 works and re-measures can be controlled through the control buttons 11 and the controller 9. By measuring the water temperature, the data difference between the water temperature measured by the temperature detection probe of the temperature protection device caused by the loss of water temperature can be reduced, thereby further improving the accuracy of the test.

[0018] A plurality of mounting brackets 15 are axially fixed on the serpentine tube 1. A plurality of rollers 16 are rotatably connected to the mounting brackets 15 at equal angles around the serpentine tube 1 as the axis.

[0019] The rollers 16 can roll in a narrow environment, so as to facilitate the insertion of the serpentine tube 1 and the hoses 3 into a narrow space for test work, improving the adaptability.

[0020] The above is a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principle and spirit of the present invention, the changes, modifications, substitutions and variations made to the implementation manners still fall within the protection scope of the present invention.
