Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to a fixing device for a guide support rod in a hole for reverse pressure cutting of a wire saw. Background Art

[0002] For the construction of reverse pressure cutting of a wire saw, a guide hole needs to be drilled, a guide support rod is installed in the hole, and a fixing frame is installed at the hole opening to fix the guide support rod in the hole. The fixing frame usually uses an electric drill to drill holes and insert expansion bolts for fixing. If the rock at the hole opening is relatively broken, the fixing effect is not good, and it is easy to cause the guide support frame in the hole to float under the pressure of the wire saw.

When the fastener is screwed down, the fastener presses down the upper fixing ring, and the upper connecting rod and the lower connecting rod hinged between the upper fixing ring and the lower fixing ring are stretched open, so that the outer side surface of the support plate is tightly supported on the hole wall, thereby firmly fixing the guide support rod in the hole.

[0013] 2) Simple structure, easy operation, firm support, reusable, energy-saving and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0015] Figure 1 It is the main view of the present utility model.

[0016] In the figure: fastener 1, upper fixing ring 2, lower fixing ring 3, support plate 4, supporting ring 5, upper connecting rod 6, lower connecting rod 7, guide support rod 8, tightening piece 9, clamping block 10, handle 11. DETAILED DESCRIPTION

[0017] like Figure 1 As shown, a device for securing a guide support rod in a back-pressure cutting hole for a wire saw comprises a fastener 1, an upper retaining ring 2, and a lower retaining ring 3. The fastener 1, upper retaining ring 2, and lower retaining ring 3 are all annular and freely fit over a guide support rod 8 in descending order. A support ring 5 is welded to the bottom end of the guide support rod 8, and the top surface of the support ring 5 supports the lower retaining ring 3.

[0018] Multiple sets of perforated ear plates are welded to the outer walls of the upper and lower fixing rings 2 and 3, and the upper fixing ring 2 is hingedly connected to multiple sets of upper connecting rods 6 through the perforated ear plates, while the lower fixing ring 3 is hingedly connected to multiple sets of lower connecting rods 7 through the perforated ear plates. The other ends of the upper connecting rods 6 and the other ends of the lower connecting rods 7 are hingedly connected through the support plate 4.

[0019] The upper connecting rod 6 includes a first rod, a second rod, and a third rod, and the first rod, the second rod, and the third rod are arranged at intervals of 120° outside the upper fixing ring; the lower connecting rod 7 includes a fourth rod, a fifth rod, and a sixth rod, and the fourth rod, the fifth rod, and the sixth rod are arranged at intervals of 120° outside the lower fixing ring 3.

[0020] An external thread is formed on the outer side of the upper end of the guide support rod 8 , and an internal thread is formed on the inner wall of the fastener 1 . The fastener 1 is threadedly connected to the guide support rod 8 .

[0021] The fastener 1 has multiple grooves on its upper circumference, and the corresponding tightening members 9 are engaged with the grooves on the fastener 1 through the clamping blocks 10, so that when the tightening members 9 rotate, the fastener 1 rotates. In addition, there are handles 11 on the left and right sides of the tightening members 9 for easy operation.

[0022] Working principle and process:

[0023] 1) After the wire saw counter-pressure cutting guide hole is drilled, place the guide support rod 8 into the hole, adjust the direction of the guide wheel at the bottom of the hole to be consistent with the cutting surface, and mark the top of the guide support rod 8.

[0024] 2) Put the fastener 1, the upper fixing ring 2 and the lower fixing ring 3 on the guide support rod 8, place the lower fixing ring 3 on the supporting ring 5, and thread the fastener 1 to the guide support rod 8.

[0025] 3) When the fastener 1 presses down on the upper fixing ring 2 and feels the force, buckle the tightening piece 9 on the fastener 1 and rotate it with force. The fastener 1 presses down on the upper fixing ring 2, and the multiple groups of upper connecting rods 6 and lower connecting rods 7 hinged between the upper fixing ring 2 and the lower fixing ring 3 are stretched open, so that the outer side surface of the support plate 4 is tightly supported on the wall of the guide hole, thereby fixing the guide support rod 8 in the hole.

[0026] 4) After the cutting work is completed, loosen the fastener 1 with the fastener 9, remove the device, take out the guide support rod 8 to the outside of the guide hole, and turn to the next cycle of work.
