[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] like Figure 1 As shown, this utility model provides a spacer deployment structure, including a sleeve rod 11, with a deployment rod 10 sleeved inside the sleeve rod 11. A hook 12 is fixedly connected to the bottom end of the deployment rod 10, and a spacer is suspended on the hook 12. The surface of the sleeve rod 11 is also provided with a scale for displaying the deployment depth.

[0028] Example 1

[0029] like Figure 2 As shown, the spacer includes a fixing component and a receiving bag 18. The receiving bag 18 is made of waterproof material, which can both hold liquid explosives and isolate the blast hole from the humid environment. Both the fixing component and the receiving bag 18 have wire holes 19, and the two are connected by ropes for suspension. Figure 3 As shown, the fixing assembly includes a support plate 14 with a through hole at its center, and an anti-disengagement buckle 13 is installed inside the through hole. The anti-disengagement buckle 13 includes a connecting rod 1302 located inside the through hole; an upper lifting ring 1301 is fixedly connected to the top of the connecting rod 1302, and a limiting plate 1303 is fixedly connected to the bottom of the connecting rod 1302. The diameter of the limiting plate 1303 is larger than the diameter of the through hole, and a lower lifting ring 1304 is fixedly connected to the bottom wall of the limiting plate 1303. The upper lifting ring 1301 is suspended on the hook 12, and the lower lifting ring 1304 is connected to the receiving bag 18 via a traction rope 26.

[0030] The support plate 14 and the sleeve rod 11 are also equipped with matching limiting components to maintain the fixed connection between the sleeve rod 11 and the support plate 14 when the upper lifting ring 1301 is broken. Figure 3As shown in FIG. 4, the limiting assembly includes a limiting ring 29 fixedly connected to the outer periphery of the through hole and two limiting blocks 28 fixedly connected to the inner side wall below the support disc 14, and a right-angled groove 30 is formed in the outer wall of the limiting ring 29 and matched with the two limiting blocks 28. During the process of sleeving the sleeve rod 11 on the limiting ring 29, the limiting blocks 28 first enter the vertical groove of the right-angled groove 30, and then the sleeve rod 11 is rotated to make the limiting blocks 28 enter the horizontal groove of the right-angled groove 30, thereby limiting the sleeve rod 11 and the support disc 14 in the vertical direction, preventing the relative position of the sleeve rod 11 and the support disc 14 in the vertical direction from changing, providing support for the subsequent operation of pulling off the upper ring 1301, and avoiding the support disc 14 and the containing bag 18 from falling at the same time.

[0031] The fixing assembly further includes a plurality of notches 17 arranged around the support disc 14, the notches 17 penetrating through the side edges and the upper and lower surfaces of the support disc 14, and each notch 17 is provided with an expansion claw 15 with a top portion inclined inward, and the middle portion of the expansion claw 15 is connected to the support disc 14 through a rotating shaft. Figure 2 As shown in FIG. 5, a threading hole 19 is formed in the top portion of the expansion claw 15, the top portion of the expansion claw 15 is connected to the containing bag 18 through a control rope 27, and the length of the traction rope 26 is shorter than that of the control rope 27, so that the containing bag 18 only bears the tension of the traction rope 26 during the process of being put into the hole.

[0032] As shown in FIG. 5, a threading hole 19 is formed in the top portion of the expansion claw 15, the top portion of the expansion claw 15 is connected to the containing bag 18 through a control rope 27, and the length of the traction rope 26 is shorter than that of the control rope 27, so that the containing bag 18 only bears the tension of the traction rope 26 during the process of being put into the hole. Figure 6 As shown in FIG. 5, a threading hole 19 is formed in the top portion of the expansion claw 15, the top portion of the expansion claw 15 is connected to the containing bag 18 through a control rope 27, and the length of the traction rope 26 is shorter than that of the control rope 27, so that the containing bag 18 only bears the tension of the traction rope 26 during the process of being put into the hole.

[0033] In use, the spacer is first placed directly above the hole, and the limiting blocks 28 of the sleeve rod 11 are placed in the horizontal groove of the right-angled groove 30; the spacer is put into the hole, and the required depth of the spacer put into the hole is known according to the scale on the sleeve rod 11; during the process of putting, the traction rope 26 is always in a taut state, and the control rope 27 is always in a loose state. Then the put-in rod 10 is pulled upward with force, the upper ring 1301 of the anti-tripping buckle 13 is pulled off, the containing bag 18 loses the tension of the traction rope 26 and falls downward due to gravity, and the control rope 27 is taut, the expansion claw 15 is rotated clockwise after being pulled by the control rope 27, the bottom portion of the expansion claw 15 expands outward, and the sharp spike 1603 is inserted into the side wall of the hole, so that the spacer is fixed in the hole. Then the sleeve rod 11 is rotated to make the limiting blocks 28 disengage from the vertical groove of the right-angled groove 30, and the sleeve rod 11 and the put-in rod 10 are taken out of the hole. Finally, the hole is backfilled, the top portion of the expansion claw 15 moves downward under the pressure of the backfilling material, the bottom portion of the expansion claw 15 expands outward, thereby providing greater support force when the spacer is fixed in the hole.

[0034] Embodiment 2

[0035] As shown in FIG. 1, the difference from Embodiment 1 is that the anti-skid component 16 is a horizontal downward extending spike 1603, which can make the spacer more and more solidly inserted into the inner wall of the blasthole due to the weight and backfill of the blasthole. Figure 7

[0036] Embodiment 3

[0037] As shown in FIG. 2, the difference from Embodiment 1 is that the anti-skid component 16 comprises a fitting plate 1601, which is hinged with the expansion claw 15, and the outer surface of the fitting plate 1601 is provided with a ratchet 1602 in a stepped shape, so that the fitting plate 1601 can form a shape matched with the ratchet 1602 by extrusion of the fitting plate 1601 on the inner wall of the blasthole when the fitting plate 1601 is fitted on the inner wall of the blasthole, and is fixed by lapping. Figure 3

[0038] Embodiment 4

[0039] As shown in FIG. 3, the difference from Embodiment 1 is that each slot 17 is provided with an expansion claw 15 with a top inclined outward, and the bottom of the expansion claw 15 is connected to the support disc 14 through a rotating shaft. The top end of the expansion claw 15 is provided with a horizontal outward extending spike 1603. Figure 8 In use, when the upper ring 1301 is pulled off, the expansion claw 15 is pulled to rotate counterclockwise when the control rope 27 is taut, so that the ratchet 1602 is inserted into the inner wall of the blasthole.

[0040] Embodiment 5

[0041] As shown in FIG. 4, the difference from Embodiment 4 is that the top end of the expansion claw 15 is provided with a horizontal downward extending spike 1603.

[0042] Figure 9 Embodiment 6

[0043] As shown in FIG. 5, 11, the difference from Embodiment 3 is that the slot 17 only penetrates the upper and lower surfaces of the support disc 14, and the sidewall of the support disc 14 is provided with an expansion groove 20 communicated with the slot 17, and the expansion groove 20 is slidably provided with a push block 21, and the outer end of the push block 21 is fixedly connected with the fitting plate 1601. The bottom end of the expansion claw 15 is oppositely arranged with the push block 21, so that when the expansion claw 15 is rotated clockwise by the pulling force of the control rope 27, the bottom end of the expansion claw 15 can push the push block 21 to move outward, and then the fitting plate 1601 is fitted with the inner wall of the blasthole.

[0044] Embodiment 7 Figure 10 As shown in FIG. 6, the difference from Embodiment 6 is that the slot 17 is provided with a horizontal outward extending spike 1603.

[0045]
