When fixing, you only need to turn the brake block, which is inserted into the bottom of the wheel to brake. In addition, part of the weight of the motor towing test bench will be shared by the vertical rod, thereby reducing the weight of the wheel, making the wheel not easily damaged and having good braking stability.

[0006] Furthermore, the wheel is a universal wheel.

[0007] Furthermore, the vertical rod is threadedly connected to the bottom plate, and can be adjusted up and down to the height of the vertical rod.

[0008] To sum up, the beneficial effects of the utility model are as follows: the flat plate is pulled out of the rectangular frame by the pull ring, which is convenient for carrying. When fixed, the brake block is rotated to insert into the bottom of the wheel, thereby playing a braking role. Part of the weight of the motor-towed test bench will be shared by the vertical rod, thereby reducing the weight of the wheel, making the wheel not easily damaged and having good braking stability.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1-4 As shown, a motor pair test bench includes a companion motor 1, a motor under test 2, a torque sensor 3 and a torque and speed measuring instrument, wherein the torque sensor 3 is connected to the companion motor 1 and the motor under test 2, and the torque and speed measuring instrument is connected to the torque sensor 3. The companion motor 1, the motor under test 2 and the torque sensor 3 are all arranged on a rectangular platform 4, and the platform 4 is a cast iron platform. These structures all belong to existing products, such as the existing motor comprehensive performance test system 45KW synchronous motor asynchronous motor loading test bench motor pair test bench. The rated power is 45kw, the rated speed is 1500rpm, and the rated torque is 286Nm. The product adopts the motor under test and the companion motor to be loaded in the form of motor pair through the torque and speed sensor in series, and detects the motor torque, speed, and power values.

[0016] The improvement of this product is that: pull rings 41 are provided at the four top corners of the upper surface of the platform 4, and the platform 4 is detachably connected to the top surface of the rectangular frame 5, that is, the inner circle of the rectangular frame 5 forms an L-shaped recess, and the platform 4 is also rectangular, and the platform 4 is just placed in the L-shaped recess. The lower surface of the top corner of the rectangular frame 5 is provided with a column 51, and the column 51 is connected to the lower surface of the rectangular frame through an inclined rod 52, and the column in front of the rectangular frame 5 and the column in the back are connected through a reinforcing shaft. The bottom of each column 51 is connected to the bottom plate 53, and the bottom of the bottom plate 53 is connected to the wheel 6 and the brake structure 7. The wheel 6 is a universal wheel, which is an existing product.
