Description

TECHNICAL FIELD

[0001] The utility model relates to a rubber pipe heat resistance testing equipment. BACKGROUND

[0002] The rubber pipe is a common component in the engineering equipment and mechanical field, and the heat resistance of the rubber pipe needs to be detected during product research and development to confirm the heat resistance of the rubber pipe, especially the fire resistance of the rubber pipe.

[0003] However, in the test method, the heat source only heats one side surface of the rubber pipe, and the heated surface of the rubber pipe is rapidly aged and damaged by single-sided heating, and the heat resistance and damage degree of the other side cannot be confirmed, and the detection result of single-sided heating is not conducive to accurately evaluating the heat resistance of the rubber pipe.

[0004] Therefore, it is necessary to provide a new rubber pipe heat resistance testing equipment. UTILITY MODEL CONTENT

[0005] The utility model aims at overcoming the defects of the prior art and providing a new rubber pipe heat resistance testing equipment.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rubber pipe heat resistance testing equipment for testing the heat resistance of the rubber pipe and the joint assembly at both ends of the rubber pipe, comprising: an adapter connector connected to the joint assembly, and a pipeline assembly connected to the adapter connector; the outer end of the two joint assemblies is fixedly connected to a part of the adapter connector in the radial direction, and the other part of the adapter connector in the radial direction is fixedly connected to the pipeline assembly; the inner and outer parts of the adapter connector in the radial direction can rotate relative to each other; the rubber pipe and the joint assembly are rotatably connected to the pipeline assembly; and a driven wheel and a driving wheel are further included, one of which is fixedly connected to a part of the adapter connector in the radial direction and connected to the joint assembly, and the driven wheel is driven to rotate by the driving wheel, thereby rotating the rubber pipe and the joint assembly.

[0007] Compared with the prior art, the utility model has the beneficial effects that: by rotating the rubber pipe and the joint assembly, the rubber pipe and the joint assembly can be heated more uniformly in a high-temperature environment, and the test result is more reliable.

[0009] Figure 2 It is a half-section schematic view of the rubber pipe heat resistance testing equipment of the utility model. DETAILED DESCRIPTION

[0010] As Figure 1 , Figure 2 shown, the hose heat resistance testing device comprises joint assemblies 21, 22 arranged at both ends of the hose 1 and connected to both ends of the hose 1 respectively, adapter joints 31, 32 connected to the joint assemblies respectively, and pipe assemblies 51, 61, 52, 62 connected to the adapter joints respectively, and driving wheels and driven wheels for driving the hose 1 and the joint assemblies.

[0011] The outer end of one of the joint assemblies 21 is fixedly connected to the radially outer portion 30 of the adapter joint 31, and the radially inner portion 33 of the adapter joint 31 is fixedly connected to the pipe assemblies 51, 61. The radially inner and outer portions 33, 30 of the adapter joint 31 can rotate relative to each other, and the hose 1 and the joint assembly 21 are rotatably connected to the pipe assemblies 51, 61, i.e. the pipe assemblies 51, 61 can be kept stationary when the hose 1 and the joint assembly 21 are rotating.

[0012] The outer end of the other joint assembly 22 is fixedly connected to the radially outer portion 30 of the other adapter joint 32, and the radially outer portion 30 of the adapter joint 32 is fixedly connected to the driven wheel 4, which is driven to rotate by the driving wheel 7, thereby driving the hose 1 and the joint assemblies 21, 22 to rotate. The radially inner portion 33 of the adapter joint 32 is fixedly connected to the pipe assemblies 52, 62. Bearings are arranged between the radially inner portions 33 and the radially outer portions 30 of the adapter joints 31, 32, so that they can rotate relative to each other, and the rotation of one of them does not interfere with the other.

[0013] In this way, the driving wheel 7 drives the driven wheel 4, which is fixedly connected to the hose 1 and the joint assemblies 21, 22, thereby driving the hose 1 and the joint assemblies 21, 22 to rotate. This makes the entire hose 1 and joint assemblies evenly heated when subjected to high-temperature testing, such as being roasted by fire, and the test results are more reliable.

[0014] In alternative embodiments, the structure of the adapter joints can be adjusted, i.e. the radially inner portions of the adapter joints 31, 32 are fixedly connected to the joint assemblies 21, 22, and the radially outer portions are fixedly connected to the pipe assemblies 51, 61, 52, 62. At the same time, the driven wheel 4 and other components are adjusted accordingly.

[0015] The pipe assemblies 51, 61, 52, 62 are in communication with the hose 1 and the joint assemblies 21, 22, and liquid can flow from the pipe assemblies 51, 61 to the pipe assemblies 52, 62, so that the hose 1 and the joint assemblies are in liquid flow when subjected to high-temperature testing.

[0016] The above specific embodiments are only for understanding the structure and working mode of the rubber pipe heat resistance testing device, and are not a limitation on the rubber pipe heat resistance testing device, and non-essential improvements made by those skilled in the art on the basis of the above are within the protection scope of the rubber pipe heat resistance testing device.
