[0013] In the figure: 1 mounting plate, 2 brake block, 3 brake chamber, 4 inner bushing, 5 guide rod, 6 guide seat, 7 spring, 8 rotating block, 9 rotating shaft mounting hole, 10 outer bushing, 11 telescopic rod, 12 handle. DETAILED DESCRIPTION

[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] See also Figure 1 or Figure 2The utility model provides a technical solution: a brake structure for remanufacturing old motors, including a mounting plate 1 for mounting at the tail end of the motor. If the motor shaft does not extend out of its tail, it needs to be modified so that the motor shaft passes through the end cover and extends out from the center hole of the mounting plate 1. The rotating block 8 in the brake is installed on the shaft through the shaft mounting hole 9. The rotating block 8 is conical. A guide rod 5 is provided on the mounting plate 1. A brake block 2 is slidably provided on the guide rod 5. A spring 7 is sleeved on the guide rod 5. One end of the spring 7 is pressed against the mounting plate 1, and the other end is pressed against the brake block 2. The end is topped on the guide seat 6 on the brake block 2. The spring 7 is used to disengage the brake block 2 from the contact state with the rotating block 8 after braking is completed, so as to facilitate the next braking. A brake cavity 3 is arranged at the center of the brake block 2. The inner wall of the brake cavity 3 is padded with an inner sleeve 4. The inner sleeve 4 is made of wear-resistant material. The brake cavity 3 is conical and the taper is the same as that of the rotating block 8. In the non-braking state, the rotating block 8 is located in the brake cavity 3 and does not contact its inner wall. The outer sleeve 10 is arranged on the outer sleeve of the rotating block 8. The outer sleeve 10 is made of wear-resistant material. A driving component is arranged on the brake block 2.

[0016] When braking is required, the brake block 2 approaches and finally contacts the rotating block 8. The brake block 2 is restricted from rotating under the joint action of the plurality of guide rods 5, and the motor shaft stops rotating rapidly under the action of the friction force.

[0017] Embodiment 1

[0018] See also Figure 1 The driving component arranged on the brake block 2 is a telescopic rod 11, one end of the telescopic rod 11 is fixed on the brake block 2, and the other end is fixed on the mounting plate 1. The telescopic rod 11 is an electric telescopic rod, a hydraulic telescopic rod or a pneumatic telescopic rod. When braking, the telescopic rod 11 is shortened to make the brake block 2 contact with the rotating block 8 to achieve the braking purpose.

[0019] Embodiment 2

[0020] See also Figure 2 The driving component arranged on the brake block 2 is a handle 12, which is fixed on the end face or side face of the brake block 2. When braking, the worker holds the handle to push the brake block 2 toward the rotating block 8, and finally the brake block 2 contacts the rotating block 8 to achieve the braking purpose.
