Background
Furnace rollers refer to rolling parts used in industrial furnaces or high-temperature equipment, and are commonly found in metallurgical, chemical and other industries. It mainly plays a role in supporting and conveying materials. The furnace rollers are typically made of a high temperature, wear resistant material such as superalloy steel, stainless steel, and the like. They need to be able to withstand the high pressures and friction in high temperature environments while having good corrosion resistance.
Furnace rollers are important components in industrial furnaces or high temperature equipment, the balance of which directly affects the stability of the equipment. The unbalance condition of the furnace roller can be detected and adjusted through dynamic balance test, so that the furnace roller can be ensured not to cause serious vibration and noise when rotating at high speed, and the running stability of equipment is improved. Unbalanced furnace rolls can cause additional vibration and shock to the equipment, exacerbating wear and damage to the equipment. The unbalance problem of the furnace roller is found and regulated in time through dynamic balance test, so that the loss of equipment can be reduced, and the service life of the equipment can be prolonged. Furthermore, unbalanced furnace rolls increase the energy consumption of the apparatus, as unbalance can lead to additional friction and energy loss. The balance performance of the furnace roller is adjusted through dynamic balance test, so that the energy consumption can be reduced, and the energy efficiency of the equipment is improved. Finally, the well-balanced furnace roller can ensure the uniform heating or cooling of the materials in the furnace, and improves the production efficiency and the product quality.

Meanwhile, when the furnace roller is used, heavy objects are required to be conveyed and larger load is required to be borne, so that the load capacity of the furnace roller is also an important detection item in the detection of the furnace roller, and the load capacity test of the furnace roller is carried out in the dynamic balance test, so that the detection efficiency of the furnace roller can be greatly improved.

After the arc-shaped lifting plate 72 extends out of the arc-shaped chute, the first test furnace roller 6 can be lifted.
Working principle:
When the testing machine works, the first testing furnace roller 6 can be arranged between the testing host machine 1 and the base 2, one end of the first testing furnace roller 6 is clamped in the first driving connector 111, the other end of the first testing furnace roller 6 is clamped in the second driving connector 211, when the driving motor drives the first driving connector 111 to rotate, the first driving connector 111 can drive the first testing furnace roller 6 to rotate, and a sensor, a data acquisition system and a control system are arranged in the testing host machine 1 and can measure and analyze the vibration condition of the first testing furnace roller 6 during rotation so as to carry out accurate balance adjustment;
The first test furnace roller 6 rotates to drive the second driving joint 211 to rotate, the second driving joint 211 rotates to drive the driving gear 35 to rotate, the driving gear 35 rotates to drive the driven gear 31 to rotate, the eccentric rod 32 rotates along with the rotation of the driven gear 31, and when the eccentric rod 32 rotates to a low position, the eccentric rod 32 falls onto the first test furnace roller 6 through the load block 34 hinged with the connecting rod 33, and the load is simulated to be conveyed by the furnace roller, so that the load capacity detection of the first test furnace roller 6 is realized while the dynamic balance test is performed;
When the first test furnace roller 6 is tested and needs to be replaced by the second test furnace roller 8, the driving motor is stopped, the eccentric rod 32 rotates to a high position, the eccentric rod 32 is separated from the first test furnace roller 6 through the load block 34 hinged with the connecting rod 33, the base 2 is pushed by the hydraulic push rod 13 at the moment, the base 2 is far away from the test host 1, the second driving connector 211 is separated from the first test furnace roller 6, the driving gear 35 stops rotating, the driving gear 35 and the driven gear 31 can be locked by the locking component 36, and the first test furnace roller 6 can be conveniently disassembled at the moment;
when the base 2 slides in a direction away from the test host 1, the first rack 221 drives the first driving gear 411 to rotate forward, and when the first driving gear 411 rotates forward, the bracket 42 can be driven to slide in a direction towards the test host 1;
The second test furnace roller 8 and the first test furnace roller 6 are positioned on the same horizontal plane, and can be conveniently installed on the test host 1 after the bracket 42 approaches the test host 1;
When the bracket 42 slides on the second sliding rail 43 towards the direction of the test host 1, the second rack 422 drives the second driving gear 73 to rotate forward, when the second driving gear 73 rotates forward, the arc lifting plate 72 slides outwards in the arc sliding groove, the arc lifting plate 72 stretches out of the arc sliding groove, after the arc lifting plate 72 stretches out of the arc sliding groove, the first test furnace roller 6 can be lifted, the base 2 is prevented from being separated from the first test furnace roller 6 far away from the second driving joint 211 of the test host 1, and the first test furnace roller 6 and the first driving joint 111 bear huge gravity, so that the first test furnace roller 6 bends to influence the performance of the first test furnace roller 6;
After the first test furnace roller 6 is detached from the test host 1, one end of the second test furnace roller 8 is clamped in the first driving joint 111, so that the installation of the second test furnace roller 8 can be completed, and at the moment, the base 2 is pulled by the hydraulic push rod 13, so that the base 2 slides towards the direction close to the test host 1;
when the base 2 slides towards the direction approaching the test host 1, the first rack 221 drives the first driving gear 411 to rotate reversely, and when the first driving gear 411 rotates reversely, the bracket 42 can be driven to slide towards the direction away from the test host 1;
When the bracket 42 slides on the second sliding rail 43 in the direction away from the test host 1, the second rack 422 drives the second driving gear 73 to rotate reversely, and when the second driving gear 73 rotates reversely, the arc-shaped lifting plate 72 slides inwards in the arc-shaped sliding groove, and the arc-shaped lifting plate 72 is hidden in the arc-shaped sliding groove;
Then, along with the sliding of the base 2 towards the direction approaching to the testing host 1, finally, the other end of the second testing furnace roller 8 is clamped in the second driving joint 211, the base 2 stops moving, the testing host 1 is started at this moment to repeat the detection steps, so that the second testing furnace roller 8 can be tested, the next furnace roller to be tested can be placed on the bracket 42 at this moment, and batch testing of the furnace rollers can be performed by repeating the steps.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention.
