The invention adopts the technical scheme that the integral connection structure comprises a main reducer assembly and a brake assembly, which are arranged between a frame front crossbeam and a frame rear crossbeam, wherein the rear end of the main reducer assembly is fixedly connected with the frame rear crossbeam through a rear fixed support, the brake assembly is arranged inside a space which is formed among an upper guide groove, a lower guide groove and the frame front crossbeam, and the integral connection structure also comprises calipers supports, wherein two sides of the main reducer assembly are respectively provided with one calipers support, an annular ring end of each calipers support is sleeved on the main reducer assembly, and the brake end is connected with the frame front crossbeam. The connection structure has the advantages of excellent stress, good rigidness, small arrangement space, fewer components, small arrangement difficulty, convenience in disassembling of the entire car and convenience in disassembling and maintenance.

The invention discloses a vertical mill speed reducer. The vertical mill speed reducer comprises a box, hydrostatic bearings arranged in the box, and an output flange arranged on the upper portion of the box. At least two hydrostatic bearings are arranged in the box in the circumferential direction and are each provided with a hoisting ring used for being connected with a traction device. Fixed parts used for being connected with the traction devices are arranged in the middle of the box. The output flange is provided with through holes corresponding to the hydrostatic bearings, and the area of the through holes is larger than the section area of the hydrostatic bearings. The outer circumference of the box is provided with observation windows corresponding to the hydrostatic bearings in position. The hydrostatic bearings, the observation windows and the fixed parts are located on the same straight line. Through the vertical mill speed reducer, on-line maintenance performance of the hydrostatic bearings of the ultra-large vertical mill speed reducer is achieved, the condition that after a fault occurs to the hydrostatic bearings, the vertical mill speed reducer has to be pulled out of the lower portion of a mill so as to maintain and replace the hydrostatic bearings is avoided, thus a large amount of maintenance time is saved, a large amount of maintenance cost is reduced, and the security risk occurring when the speed reducer is pulled out is avoided completely.

LED (Light Emitting Diode) lamp for light string

The invention relates to an LED (Light Emitting Diode) lamp for a light string. The LED lamp for the light string comprises a shell and a circuit board. The shell is characterized by comprising a bottom cover, a fixed plate and a transparent hood. The transparent hood and the bottom cover are fixed together to form a base shell provided with an accommodating chamber. The fixed plate is arranged in the accommodating chamber of the base shell. A slot for a lead to pass through and embed is arranged on the bottom surface of the fixed plate. The bottom cover shields the opening at the bottom of the slot. The circuit board is arranged between the fixed plate and the transparent hood. A first conductive felting needle and a second conductive felting needle are arranged on the fixed plate in a penetrating way. The upper ends of the first felting needle and the second conductive felting needle exposes out of the top surface of the fixed plate and are respectively conducted with the cathode access point and the anode access point of a power supply in the circuit board. The lower ends of the first conductive felting needle and the second conductive felting needle are located in the slot for piercing a surface insulating layer of the lead embedded into the slot and being contacted with the lead. According to the LED lamp for the light string, fewer parts are involved, and the LED lamp for the light string is simple in structure and convenient to assemble.
