DETAILED DESCRIPTION

[0018] See also Figure 1-Figure 3A maintenance device for a crane comprises a lifting platform 1 and a panel 2, wherein the panel 2 is concave and fixed to the outer side of the upper end of the lifting platform 1, a rotating mechanism 9 is installed in the middle of the upper end of the lifting platform 1, a column 10 is installed in the middle of the upper end of the rotating mechanism 9, a side rod 11 is fixed to the upper side of the column 10, and a maintenance tool box 12 is fixed to the end of the side rod 11, and the lifting mechanism of the lift is installed below the lifting platform 1. In this way, a rotating mechanism 9 is directly installed on the lifting platform 1, and a column 10 is arranged on the rotating mechanism 9. A side rod 11 is vertically arranged on one side above the column 10, and a maintenance tool box 12 is directly fixed to the end of the side rod 11. In this way, maintenance tools of the crane, such as a multimeter, a voltmeter and the like, are placed in the maintenance tool box 12, so that when the maintenance personnel change the position on the lifting platform 1, they can directly push the side rod 11, so that the column 10 rotates through the rotating mechanism 9, which can drive the maintenance tool box 12 to rotate and change the position together. In this way, there is no need for workers to change the position of the maintenance tool box 12 by holding it, which is convenient for maintenance personnel to use the maintenance tool box 12 to perform crane maintenance work.

[0019] A protective door 3 is hinged on the left side of the front end of the enclosure 2, and a lock groove 4 is opened on the other side of the upper end of the protective door 3. A fixing seat 5 is fixed on the upper right side of the front end of the enclosure 2, and a lock hole 6 is provided in the middle of the fixing seat 5. An L-shaped seat 7 is fixed to the rear side of the upper end of the fixing seat 5. A through hole is provided on the upper end of the L-shaped seat 7, and the aperture of the through hole matches the aperture of the lock hole 6. A lock column 8 is inserted into the through hole, and the lock column 8 is inserted into the lock hole 6 and the lock groove 4. After the crane maintenance personnel walk onto the lifting platform 1, they close the protective door 3 and make the lock groove 4 of the protective door 3 and the lock hole 6 of the fixing seat 5 on the same vertical line, and finally press the lock column 8 downward, so that the lock column 8 will pass through the lock hole 6 of the fixing seat 5 and be inserted into the lock groove 4 of the protective door 3, so as to limit the protective door 3.

[0020] The outer wall of the lock column 8 is provided with a rubber coating 15, and the rubber coating 15 is in close contact with the inner wall of the lock hole 6. By providing the rubber coating 15 on the outer wall of the lock column 8, the sliding friction between the lock column 8 and the lock hole 6 of the fixing seat 5 can be improved, thereby improving the stability of the lock column 8 after being inserted into the lock groove 4.

[0021] A concave-shaped frame 13 is fixed to the inner wall of the enclosure 2, and fixed rods 14 are fixed between the two ends of the frame 13 and the inner wall of the enclosure 2. By arranging the frame 13 on the inner side of the enclosure 2, it is convenient for maintenance personnel to hang a safety rope on the frame 13. The frame 13 is arranged in a concave shape, and only the two ends are fixed by the fixed rods 14. There is no fixed structure in the middle part of the frame 13 to prevent the hook from sliding. In this way, maintenance personnel do not need to manually change the hook hung on the frame 13 when walking, which is convenient for maintenance personnel.

[0022] The rotating mechanism 9 includes a fixed plate 91, a rotating plate 93, a gear 96, a nut 97 and a stud 98. The fixed plate 91 is fixed to the elevator platform 1.

Balls 94 are rollingly connected inside the rolling grooves. The upper part of the ball 94 is rollingly connected to the bottom of the rotating plate 93. When the column 10 needs to rotate, it can drive the rotating plate 93 to rotate. When the rotating plate 93 rotates inside the groove 92, the ball 94 at the bottom of the groove 92 can roll with the bottom of the rotating plate 93, which is beneficial to the rotation of the rotating plate 93.

[0023] The inner wall of the groove 92 is provided with an annular groove 95, the gear 96 is fixed on the outside of the rotating disk 93, the gear 96 is located inside the annular groove 95, the nut 97 is fixed on one side of the upper end of the fixed disk 91, the stud 98 is threadedly connected to the inside of the nut 97, the lower part of the stud 98 passes through the inside of the annular groove 95, the lower part of the stud 98 abuts against the teeth of the outer wall of the gear 96, when it is necessary to limit the position of the maintenance tool box 12, the maintenance personnel can rotate the stud 98, as the stud 98 and the nut 97 are threadedly matched, the stud 98 moves down between the teeth of the outer wall of the gear 96 inside the annular groove 95, in this way, the gear 96 can be limited by the teeth abutting against the outer wall of the stud 98 and the gear 96, so as to limit the rotating disk 93, thereby limiting the position of the maintenance tool box 12, which is also convenient for limiting the position of the maintenance tool box 12, so that the maintenance personnel can choose to change the orientation or limit the position of the maintenance tool box 12 according to their choice.

[0024] Working principle: The lifting mechanism of the lift is installed below the lift platform 1, and the lifting mechanism of the lift lifts the lift platform 1 to enable the maintenance personnel to reach the part above the crane that needs maintenance. Before use, the crane maintenance personnel walk onto the lift platform 1, close the protective door 3, and make the lock slot 4 of the protective door 3 and the lock hole 6 of the fixed seat 5 on the same vertical line, and finally press down the lock column 8, so that the lock column 8 will pass through the lock hole 6 of the fixed seat 5 and insert into the lock slot 4 of the protective door 3, so as to limit the protective door 3. The maintenance personnel can hang the safety rope on the fence 13, and put the maintenance tools of the crane, such as a multimeter and a voltmeter, into the maintenance tool box 12. When the maintenance personnel change the position on the lifting platform 1, they can directly push the side rod 11, so that when the column 10 needs to be rotated, the rotating disk 93 can be driven to rotate, and the maintenance tool box 12 can be driven to rotate and change the position together. In this way, there is no need for workers to change the position of the maintenance tool box 12 by holding it, which makes it convenient for maintenance personnel to use the maintenance tool box 12 to perform crane maintenance work.
