[0002] According to the belt conveyor safety regulations, the belt conveyor head drive, tensioning part and all exposed rotating and moving parts should be equipped with protective covers and protective nets. The protective nets are generally required to be easy to install and disassemble. At present, the installation of the belt conveyor head drive to the tensioning part protective net is mainly by hook suspension ( Figure 1 , Figure 2 There are two forms of fixing: hanging and bolting. The disadvantage of using hanging is that it is inconvenient to inspect and clean the coal. The outer dimensions of the guard net are about 2930mm×1400mm and weigh about 30kg. At least two miners are required to disassemble and assemble the guard net, which is labor-intensive and inefficient. The disadvantage of bolting is that the underground environment is harsh, the bolts are prone to rust, and it is extremely inconvenient to disassemble and assemble.

[0003] The protective net was redesigned and a new one was constructed to further reduce the labor intensity of workers and bring convenience to the majority of mine workers. Utility Model Content

[0025] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0026] like Figure 2 , Figure 3 , Figure 4 As shown: a slidable protective net for a belt conveyor, comprising a double track and a protective net 1; the double track is installed between the legs 2 of the belt conveyor, and the adjacent double tracks are connected in a line, and the double track comprises an inner track 3 and an outer track 4 arranged side by side;

[0027] In the first state, the guard net 1 is hung under the inner track 3 through the sliding part at the top, and the guard nets 1 under the inner track 3 are mutually restricted, and the guard net 1 cannot slide at the corresponding position of the belt conveyor;

[0028] A translation channel is provided between the inner track 3 and the outer track 4, and the position of the translation channel is aligned with the position of the sliding part at the top of the protective net 1;

[0029] In the second state, the sliding portion of the protective net 1 enters the outer track 4 through the translation channel, and the protective net 1 slides in the outer track 4.

[0030] When the whole equipment is installed, all the guard nets 1 are installed on the inner track 3. When a certain guard net 1 needs to be opened for operation, it is only necessary to pull the guard net 1 here to the outer track 4 and push it forward or backward to operate here without disassembly. It is more convenient, quick, safe and reliable. After the operation is completed, the guard net 1 is moved to its original position by the same operation.

[0031] The inner rail 3 and the outer rail 4 both include a rail cavity 5, and the bottom surfaces of the inner rail 3 and the outer rail 4 are provided with a guide groove 6 that is connected to the rail cavity 5 and penetrates along the length direction thereof;

[0032] The guard net 1 is connected to the double track through two sliding parts; the sliding part at the top of the guard net 1 includes a suspension rod 7, a wheel axle 8 and a pulley 9; the suspension rod 7 is fixed to the top of the guard net 1, and the cross section of the suspension rod 7 is circular; the suspension rod 7 passes through the track cavity 5 from the guide groove 6, the wheel axle 8 is vertically fixed on the suspension rod 7, and the pulley 9 is installed on the wheel axle 8, and the pulley 9 is located on both sides of the suspension rod 7, and the pulley 9 is in rolling contact with the track cavity 5 to support the guard net 1;

[0033] A window 10 is provided on the side where the inner rail 3 and the outer rail 4 meet to allow the pulley 9 to translate between the rail cavities 5 of the two. The pulley 9 enters and exits between the inner rail 3 and the outer rail 4 through the window 10. A through groove 11 is provided on the bottom surface of the inner rail 3 and the outer rail 4 to allow the suspension rod 7 to translate between the guide grooves 6 of the two. The suspension rod 7 enters and exits between the inner rail 3 and the outer rail 4 through the through groove 11. Since the diameter of the pulley 9 is much larger than the width of the through groove 11, the pulley 9 will not fall out of the through groove 11. The window 10 and the through groove 11 constitute a translation channel.

[0034] The inner track 3 and the outer track 4 are square tubes with the same cross-section, with specifications of 80×80×4mm. The inner track 3 and the outer track 4 are in a closed state, which can prevent coal dust and other debris from entering and ensure smooth sliding of the guard net 1. The guide groove 6 is located at the center line of the inner track 3 and the outer track 4.

[0035] The distance between the legs 2 of the belt conveyor is 3000mm. To facilitate the installation of double tracks, the design length of the double tracks is 2990mm.

[0036] The double track is connected to the leg 2 of the belt conveyor through the angle steel 12 and bolts, the horizontal plate of the angle steel 12 is connected to the inner track 3, and the vertical plate is connected to the leg 2 of the belt conveyor through bolts.

[0037] The double track includes a U-shaped card 13 , which is buckled on the top of the inner track 3 and the outer track 4 .
