The two weight-adding blocks 1 are symmetrically arranged to increase the stability of the connection between the bottom of the device and the ground. The protective steel plate 3 is arranged to be fitted with the weight-adding block 1, and the protective steel plate 3 forms a vertical installation structure with respect to the weight-adding block 1. The fitting installation and vertical installation structure of the protective steel plate 3 and the weight-adding block 1 make the installation between the two more firm. The outer side of the top of the protective steel plate 3 is connected to the upper end surface of the weight-adding block 1 through a fixing bracket 4, and the outer side of the protective steel plate 3 is arranged from top to bottom according to A wire mesh 6 and a foamed plastic plate 5 are installed at the same time, and the wire mesh 6 and the foamed plastic plate 5 are connected to each other with the inner end surface of the protective steel plate 3 through a limit block 14. The foamed plastic plate 5 and the wire mesh 6 have the same width, and the foamed plastic plate 5 forms a parallel installation structure with respect to the wire mesh 6. The same width of the foamed plastic plate 5 and the wire mesh 6 increases the protective effect of the device. The shock absorber 7 is arranged at the upper end of the weight-increasing block 1, and a fixing block 10 is installed at the lower end of the shock absorber 7. The shock absorber 7 forms a disassembly and installation structure with respect to the weight-increasing block 1, and the top of the shock absorber 7 The height is higher than the top of the protective steel plate 3, and the disassembly and installation structure is convenient for regular inspection and maintenance of the shock absorber 7.
