[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0026] like Figure 1-6 As shown, the utility model provides a device for quickly removing ground stones, comprising:

[0027] Hydraulic forklift 1;

[0028] The fixing assembly includes a positioning frame detachably connected to the two lifting arms 101 of the hydraulic forklift 1. The positioning frame can move up and down with the lifting arms 101 of the hydraulic forklift 1. The positioning frame is detachably connected to an extended screw expansion bolt 7 to fix the stone through the expansion bolt 7.

[0029] In this technical solution, the hydraulic forklift 1 is a manual hydraulic forklift 1, which includes a mobile bracket 103, a drive assembly 102, and two lifting arms 101 that can slide up and down relative to the mobile bracket 103. The drive assembly 102 is arranged on the mobile bracket 103 to drive the two lifting arms 101 to rise or fall. The specific settings of the hydraulic forklift 1 all adopt existing technologies; the expansion bolt 7 is driven into the drilled hole and fixed by the second nut. Before using the hydraulic forklift 1, a hole is drilled on the stone, and the hole diameter is adapted to the expansion bolt 7.

[0030] How to use: first drill a hole in the stone, then connect the positioning frame to the hydraulic forklift 1, hammer the expansion bolt 7 into the drilled hole, and then connect the upper end of the expansion bolt 7 to the positioning frame. Lift the lifting arm 101 of the hydraulic forklift 1, and the positioning frame will rise as the lifting arm 101 rises until the stone is higher than the surrounding stones. Move the hydraulic forklift 1 to the place where the old stones are piled, separate the expansion bolt 7 from the positioning frame, and complete the removal of a piece of stone. After all stones are removed, separate the positioning frame from the hydraulic forklift 1.

[0031] By adopting this technical solution, the utility model fixes the removed stone by setting a hydraulic forklift 1 and a fixing component, effectively reducing damage to surrounding stones; and fixes the removed stone on the device for quickly removing ground stones by setting a positioning frame and expansion bolts 7.

[0032] In another technical solution, the positioning frame includes a galvanized channel steel 2 and a galvanized steel plate 3 provided at one end of the galvanized channel steel 2. The upper end of the expansion bolt 7 is detachably connected to the galvanized channel steel 2. This technical solution is used to achieve the connection between the expansion bolt 7 and the positioning frame.

[0033] In another technical solution, an opening 10 is formed through the web of the galvanized channel steel 2 (the bottom end of the galvanized channel steel 2 is the web). The upper end of the expansion bolt 7 is secured to the opening 10 via two upper and lower first nuts. The horizontal cross-section of the opening 10 is U-shaped. This technical solution achieves a detachable connection between the expansion bolt 7 and the galvanized channel steel 2.

[0034] In another technical solution, each first nut is provided with a corresponding rubber washer 6 and a flat washer. This technical solution is used to fix the expansion bolt 7.

[0035] In another technical solution, the two flanges of the galvanized channel steel 2 (the flanges of the galvanized channel steel 2 are the two vertical side walls) are penetrated by connection holes (the connection holes are arranged horizontally). The two connection holes (the two connection holes are arranged coaxially) are passed through a steel wire rope 4. The ends of the steel wire rope 4 are detachably connected to the two lifting arms 101 of the hydraulic forklift 1, and the steel wire rope 4 does not interfere with the expansion bolts 7 in space. This technical solution realizes a detachable connection between the positioning frame and the hydraulic forklift 1.

[0036] In another technical solution, both ends of the steel wire rope 4 are sequentially connected to the lifting arm 101 of the hydraulic forklift 1 via four U-shaped fixing clips 9 (four are provided at each end of the steel wire rope 4). The distance between any two adjacent fixing clips 9 is 14 cm. In the direction away from the lifting arm 101 of the hydraulic forklift 1, the two steel wire ropes 4 (one end of the steel wire rope 4 is folded around the lifting arm 101 of the hydraulic forklift 1 for fixation) between the first fixing clip 9 (the fixing clip 9 closest to the lifting arm 101 of the hydraulic forklift 1 is the first, and the fixing clip 9 farthest from the lifting arm 101 of the hydraulic forklift 1 is the fourth) and the third fixing clip 9 fit in place. The length difference between the two steel wire ropes 4 between the third and fourth fixing clips 9 is 10 cm. Using this technical solution, the utility model achieves the fixation of the steel wire rope 4 by providing the fixing clips 9.

[0037] In another technical solution, a rubber gasket 8 is provided on the lifting arm 101 of the hydraulic forklift 1, and the steel wire rope 4 is located on the rubber gasket 8. With this technical solution, the present invention reduces the friction between the steel wire rope 4 and the lifting arm 101 of the hydraulic forklift 1 by providing the rubber gasket 8.

[0038] In another technical solution, the galvanized channel steel 2 is circumferentially provided with a plurality of extrusion components, and the extrusion components include a fixed block 11 connected to the galvanized channel steel 2 (the fixed block 11 is long and horizontally arranged), and the fixed block 11 is provided with a long through-hole 12 (which passes through the fixed block 11 up and down), and the vertical cross-section of the through-hole 12 is T-shaped, and a T-shaped connecting rod 13 is provided in the through-hole 12 (the connecting rod 13 is vertically arranged), and the connecting rod 13 is provided with a slide 14 that can slide up and down, and a gravity block 16 is connected to the lower end of the slide 14, wherein a spring 15 is provided in the slide 14 (the spring 15 is vertically arranged), and the spring 15 is connected to the connecting rod 13, and the fixed block 11 is provided with two rows of threaded holes 18 (the threaded holes 18 are horizontally arranged), and the two rows of threaded holes The threaded holes 18 are respectively located on both sides of the through-hole 12 and the threaded holes 18 are connected to the through-hole 12. A screw 17 is provided for each row of threaded holes 18. When the connecting rod 13 is adjusted to a suitable position, the screw 17 is screwed into the corresponding threaded hole 18. The end of the screw 17 abuts against the connecting rod 13. During use, the expansion bolt 7 on the threaded rod 5 is first connected to the drilled hole, and then the threaded rod 5 is connected to the opening 10. At this time, the gravity block 16 is located on the circumferential stone, and the spring 15 is compressed to the shortest state. Then, the lifting arm 101 is moved upward to separate the stone from the surrounding stones. At this time, the spring 15 is still in a compressed state. Then, the lifting arm 101 is continued to be moved upward to separate the gravity block 16 from the surrounding stones. During use, the position of the connecting rod 13 can be adjusted according to the size and shape of the stone. By adopting this technical solution, the utility model fixes the stones around the stone to be removed by setting an extrusion component, thereby avoiding affecting the stability of the surrounding stones when the stone moves up; by setting the through-hole 12, the screw 17, and the threaded hole 18, the position of the connecting rod 13 can be adjusted so that the rapid ground stone removal device can be suitable for fixing stones of different shapes and sizes, thereby improving the use range of the rapid ground stone removal device; by setting the spring 15, the slide 14, and the gravity block 16, the surrounding stones can be squeezed to avoid damaging the surrounding stones.

[0039] In another technical solution, one of the fixing blocks 11 is arranged along the length direction of the opening 10, and the corresponding through-hole 12 is connected to the opening 10, and the minimum width of the through-hole 12 is greater than the width of the opening 10. This technical solution facilitates the placement of the threaded rod 5 in the opening 10.
