[0027] The other side of the rust removal box 1 is provided with a wedge block 3, and a fixing rod 31 is provided on one side of the wedge block 3, and one end of the fixing rod 31 is fitted with the inclined surface of the wedge block 3. A slide groove 33 is opened on the other side of the rust removal box 1, and a slider 4 is fixedly installed on the side of the wedge block 3 close to the slide groove 33. A cam rod 5 is fixedly installed on one end of the transmission rod 21, and the cam rod 5 is arranged below the wedge block 3. A rubber ball 32 is detachably installed at one end of the fixing rod 31, and the two rubber balls 32 are symmetrically arranged, which is convenient for the setting of the rubber balls 32 to achieve a flexible knocking effect. The size of the slider 4 is adapted to the size of the slide groove 33, and the slider 4 is slidably connected to the slide groove 33, which is convenient for the slider 4 to cooperate with the slide groove 33, thereby ensuring the stability of the movement of the wedge block 3. A filter screen 13 is detachably installed at the lower end of the inner cavity of the rust removal box 1, and the sandblasting pipeline 12 is arranged above the filter screen 13, which is convenient for filtering the fallen sand and impurities through the filter screen 13, and further facilitating the recovery of sand and gravel.
[0028] One end of the traction rope 23 is detachably connected to the upper end of the counterweight 24 by passing through the guide wheel, and the counterweight 24 is arranged directly above the rust removal box 1, so that the counterweight 24 can be pulled by the traction rope 23, and the counterweight 24 can increase the downward gravity on the distribution cabinet, further ensuring the rust removal efficiency of the distribution cabinet.
[0029] One end of the fixing rod 31 is movably connected to the other side of the rust removal box 1, and two fixing rods 31 are provided, so that the fixing rod 31 can cooperate with the spring sleeved on the outside of the fixing rod 31, so that the fixing rod 31 drives the rubber ball 32 to move back and forth left and right.
[0030] When removing rust, first open the distribution cabinet that needs to be removed rust downward, so that the back plate of the distribution cabinet contacts and adsorbs the electromagnet 25, and then turn on the servo motor 2. The servo motor 2 drives the transmission rod 21 to reverse, and the transmission rod 21 drives the winding drum 22 on the transmission rod 21 to release the traction rope 23. The traction rope 23 drives the adsorbed distribution cabinet to move slowly downward until it moves to the top of the sandblasting pipeline 12, and performs sandblasting to sandblast the inside of the distribution cabinet to remove rust. At the same time, since the sandblasting operation is performed on the inverted distribution cabinet, the trouble of turning over the distribution cabinet to dump gravel and impurities is eliminated, and the accumulation of gravel to affect the sandblasting effect is avoided. In this way, the rust removal efficiency of the distribution cabinet is further improved. After the rust removal is completed, the servo motor 2 is controlled to drive the transmission rod 21 to rotate forward, and the transmission rod 21 drives the winding drum 22 to slowly reel in the traction rope 23.
