DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] With regard to the underground welding installation of the grating in the prior art, the operation is inconvenient, and when the grating is impacted, the welds will vibrate, and the impact will easily cause cracking and damage. The installation period is long and the maintenance rate is high, which brings a great burden to the safety production management of mines. The present application provides a grating with an assembled structure, which is composed of two integrally formed and cross-arranged support members. On the one hand, the hidden danger of cracking caused by impact on the weld is eliminated, and the assembled structure grating can be directly overlapped, and the installation process is convenient, which is conducive to underground operations.

[0030] Figure 1 The overall structural diagram of the assembled chute grille is shown; Figure 1In the present invention, the assembled chute grid includes an upper support member 100 and a lower support member 200. The upper support member 100 is overlapped on the lower support member 200 to form a grid structure with a plurality of regularly arranged leaks 400. During use, the upper support member 100 is overlapped on the lower support member 200 to form a grid structure to support and screen large pieces of ore.

[0031] Figure 2 A schematic diagram of the exploded structure of the upper support member 100 and the lower support member 200 is shown; Figure 2In the embodiment, the upper support member 100 includes two side panels 110 arranged at intervals, and a plurality of groups of ribs 120 are arranged at intervals along the length direction between the two side panels 110, and the upper end surface of each group of ribs 120 is provided with a plurality of groups of notches 121 distributed along the length direction thereof; the lower support member 200 includes two side panels 210 arranged at intervals, and a plurality of groups of ribs 220 are arranged at intervals along the length direction between the two side panels 210, and the lower end surface of each group of ribs 120 is provided with a plurality of groups of notches 221 distributed along the length direction thereof; in the installed state, the two groups of side panels 210 and the two groups of side panels 110 are alternately connected end to end to form a rectangular closed structure, and the ribs 120 and the ribs 220 are arranged crosswise to form a plurality of leaks 4 00 regularly arranged grille structure, notch 121 corresponds to notch 221 so that rib 120 and rib 220 bite each other, the upper and lower end surfaces of rib 120 and rib 220 are both in the same horizontal plane, and the end surfaces of side panel 110 and side panel 210 adjacent to each other are mutually matched inclined structures; when installing, the upper support member 100 is overlapped on the lower support member 200, at this time, the two side panels 210 and the two side panels 110 are alternately formed end to end to form a rectangular closed outer frame structure, and in the closed space, rib 220 and rib 120 are arranged crosswise, and when installing, the notch 221 opened below rib 220 bites into the notch 121 opened above rib 120 The two cross-correspond to each other, thereby forming a plurality of separated leaks 400, and the plurality of leaks 400 are regularly arranged to form a grille structure, and the depths of the second gap 221 and the first gap 121 correspond to each other, that is, after the installation is completed, the upper and lower end surfaces of the rib 220 and the side panel 1 10 are both in the same horizontal plane, which can ensure that the overall end surface of the grille is flat; the end surface where the side panel 1 10 and the side panel 2 210 meet has a positioning structure, and the positioning structure includes a step groove 111 provided on the side panel 1 10 and a step block 211 connected to the side panel 210, and in the installed state, the step block 211 is inserted into the corresponding step groove 111, and the step surface of the step groove 111 supports the lower support member 200; During installation, the end face of the second side panel 210 fits the adjacent surface of the first side panel 110 and moves downward. As the second side panel 210 continues to move downward, the step block 211 is inserted into the step groove 111. The step surface of the step groove 111 can support the lower support member 200 as a whole to prevent the lower support member 200 from falling. The width of the end of the step block 211 adjacent to the second side panel 210 is smaller than the width of the end of the step block 211 away from the second side panel 210. Specifically, it can be one of a "T"-shaped structure, a dovetail-shaped structure, a trapezoidal structure, etc., and no excessive restrictions are made here. Through the restrictions of this structure, the upper support member 100 and the lower support member 200 can be limited to separate in the horizontal direction after connection, so that the upper support member 100 and the lower support member 200 can only separate in the vertical direction.

[0032] Figure 3A schematic diagram of the structure of gap 122 is shown; Figure 3 In the installation state, rib 220 is inserted into notch 121, and there is a gap 122 between rib 220 and the side wall of notch 121; this is because the upper support member 100 needs to move downward to deform and absorb the pressure when under pressure, but when rib 120 moves downward, since the two ends of rib 120 are restricted and fixed, rib 120 deforms, and not only deformation in the vertical plane but also movement in the horizontal plane occurs. In this case, the horizontal movement of rib 120 forces rib 220 to deform in the thickness direction and forces rib 220 to twist, and the gap 122 can reserve space for relative movement between rib 120 and rib 220 to allow the two to move relative to each other.

[0033] Figure 4 A schematic diagram of the structure of gap 222 is shown; Figure 4 In the installation state, rib 120 is inserted into notch 221, and there is a gap 222 between rib 120 and the side wall of notch 221; this is because the upper support member 100 needs to move downward to absorb the pressure when under pressure, but when rib 220 moves downward, since the two ends of rib 220 are restricted and fixed, the deformation of rib 220 will not only occur in the vertical plane, but also move in the horizontal plane. In this case, the horizontal movement of rib 220 will force rib 120 to deform in the thickness direction and force rib 120 to twist, and the gap 222 can reserve space for relative movement between rib 220 and rib 120 to allow the two to move relative to each other.

[0034] Figure 5 A schematic diagram of the assembly structure of rib one 120 and rib two 220 is shown; Figure 6 shows a schematic structural diagram of the relative motion part 300; Figure 5 and Figure 6In the embodiment of the present invention, in the installed state, the rib 120 and the rib 220 have a gap on the vertical plane, and a relative motion part 300 is arranged at the gap, and the relative motion part 300 includes a lower shell 310 and an upper shell 320 that cooperate with each other, and the lower shell 310 has a plurality of rolling members 330, and the rolling members 330 include a ring 331 and a ball 332 that rolls in the ring 331, and a connecting member 350 is connected between two adjacent rings 331 to form a movable supporting surface, and the lower shell 310 and the upper shell 320 are separated by the supporting surface and a gap 340 is formed between the lower shell 310 and the upper shell 320 to allow the lower shell 310 and the upper shell 320 to slide against each other on the horizontal plane; when the upper shell 320 is translated, it can be driven The rolling element 330 rolls, thereby allowing horizontal movement, and the lower shell 310 and the upper shell 320 do not contact each other, and only a supporting surface formed by a plurality of point contacts is formed by the ball 332, thereby reducing the contact area, and sliding is rolling. The cooperation between the two can greatly reduce the friction of horizontal relative movement, so as to reduce the distortion caused by interference with horizontal deformation during downward deformation; a spring 360 is connected between the ring 331 and the lower shell 310, and the setting of the spring 360 can absorb the horizontal sliding force of the upper shell 320 relative to the lower shell 310. In summary, through the setting of the relative motion part 300, between the rib 120 and the rib 220, both the transmission of force in the vertical direction is guaranteed and the interference force in the horizontal direction can be reduced and absorbed.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
