DETAILED DESCRIPTION

[0013] As Figures 1 to 3 shown, pumping unit brake protection device, including pumping unit original brake system's brake base 1, brake lever 2, brake handle 3, lifting rod 4 and original tooth block 5, brake base 1 as the body of brake device, is formed by two identical hook-shaped tooth disc 101 arranged in parallel, and the top of the hook of tooth disc 101 is provided with one-way tooth 1011, and the brake lever 2 is arranged in the middle of the two tooth discs 101, the brake lever 2 is connected with the brake device, and the pumping unit can be slowed down and braked by pulling the brake lever 2 to the left, the brake lever 2 is provided with brake handle 3, the brake handle 3 is provided with elastic structure, when the brake handle 3 is loosened, the lifting rod 4 drops, the original tooth block 5 falls in the one-way tooth 1011 of tooth disc 101, and the position of brake lever 2 is fixed, after pressing the brake handle 3, the lifting rod 4 goes up, and the original tooth block 5 is separated from the tooth disc 101, and the locking of brake lever 2 is released;

[0014] The brake base 1 is provided with a protection assembly 6, which comprises an upper seat body 602 and a lower seat body 603 connected by bolts, and the connecting part of the upper seat body 602 and the lower seat body 603 penetrates the middle of the two tooth plates 101. The protection assembly 6 is installed on the right side of the brake lever 2. The upper seat body 602 is provided with a pull rod 601 hingedly connected to the brake lever 2. The middle part of the lifting lever 4 is provided with a cross arm 401 extending to the right side. The cross arm 401 is hingedly connected to the upper part of the upper seat body 602 through a connecting rod 7. The upper seat body 602 is provided with protection tooth blocks 605 on both sides, which fall into the guide teeth 1011 of the tooth plate 101. The lower part of the lower seat body 603 extends to both sides to form two supporting plates 6031. The lower seat body 603 is connected to a supporting plate 604 on the upper side of each supporting plate 6031 through a dovetail groove guide rail 8. A compression spring is installed between the supporting plate 604 and the supporting plate 6031. The upper part of the supporting plate 604 is in contact with the lower side of the tooth plate 101.

[0015] The protection assembly 6 is provided. When the brake handle 3 is loosened, the lifting lever 4 is lowered, and the protection tooth block 605 falls into the one-way tooth 1011 under the action of the compression spring, so that the brake lever 2 cannot move to the right. When the brake device fails, it plays a secondary protection role. After the brake handle 3 is pressed down, the lifting lever 4 rises, driving the upper seat body 602, the lower seat body 603 and the protection tooth block 605 to rise, and the protection tooth block 605 is separated from the one-way tooth 1011. The protection assembly 6 can move with the brake lever 2. The action of the protection assembly 6 follows the brake handle 3, and other operators are not required to assist in operation.

[0016] The protection tooth block 605 is embedded with a permanent magnet block 6051. The top plate of the protection tooth block 605 extends in a direction column 6052. The upper seat body 602 is provided with a square hole 6021 at the position of the square column 6052. The square hole 6021 is in interference fit with the square column 6052. The direction column 6052 is inserted into the direction hole 6021. The protection tooth block 605 and the upper seat body 602 can be installed by hot assembly, which is convenient to replace. The permanent magnet block 6051 makes the protection tooth block 605 and the one-way tooth 1011 magnetically attracted together, improving the reliability of the protection assembly 6.

[0017] Each supporting plate 604 extends upwardly to form a limiting plate 6041 on the outer side, so that the protection tooth block 605 is limited transversely and falls on the one-way tooth 1011.
