[0030] The guide rod frame for suspended rock drilling and the suspended rock drilling equipment provided in the present application are intended to solve at least one technical problem existing in the prior art.

[0031] In an embodiment of the present application, a guide rod frame for hanging rock drilling is provided, such as Figure 1-Figure 5 As shown, the guide rod frame for hanging rock drilling includes: a main frame, the main frame is hollow to form a cavity for movably fixing the underwater module 2, the underwater module 2 is used for underwater rock drilling, and the cavity is provided with an opening at the bottom of the guide rod frame 3, and the opening is used for the rock drilling end of the underwater module 2 to extend for rock drilling.

[0035] Optionally, the main frame includes stabilizing legs 301, which are arranged at the bottom of the main frame and around the opening.

[0036] In one embodiment, the cross section of the main frame is a rectangle, and the number of the stabilizing legs 301 is four, and their arrangement positions correspond one-to-one to the four corners of the rectangle.

[0037] Optionally, the stabilizing leg 301 includes a first leg and a second leg, the second leg is fixed to the side of the first leg away from the main frame, the first leg is provided with an anti-sinking flange 302, and the cross-sectional area of ​​the second leg gradually decreases in the direction away from the first leg. The anti-sinking flange 302 can be fixed to the first leg by bolts.

[0038] Optionally, the main frame includes columns 307 and connecting rods 303 , the stabilizing legs 301 are disposed at the bottom of the columns 307 , and both ends of the connecting rods 303 are connected to different columns 307 .

[0039] In one embodiment, there are four columns 307, and adjacent columns 307 are connected by connecting rods 303. In addition, the main frame can be divided into a plurality of standard segments with the same structure, and the standard segments are connected in sequence to form the main frame. In addition, the number of the standard segments can be adjusted accordingly according to the water depth, design requirements and other requirements.

[0040] In one embodiment, in order to facilitate the extraction of the drill rod from the rock after rock drilling, at least one hydraulic lifting unit 305 is fixed on the guide rod frame 3. The hydraulic lifting unit 305 is fixed inside the cavity, and the lifting end of the hydraulic lifting unit 305 is connected to the underwater module 2 to drive the underwater module 2 to move along the cavity. Specifically, one side of the hydraulic lifting unit 305 is fixed to the guide rod frame 3, and the lifting end of the hydraulic lifting unit 305 is connected to the outer side of the waterproof shell, and the drill rod is extracted from the rock by lifting the waterproof shell with the hydraulic lifting unit 305.

[0041] The hydraulic lifting unit 305 may be a hydraulic lifting cylinder, two of which are fixed on the opposite side of the waterproof housing, and the power unit is driven to move up and down along the guide rod frame 3 by the hydraulic lifting cylinder. The two hydraulic lifting cylinders can play the role of hydraulic elastic suspension, which can eliminate the excess impact energy of the underwater module 2 during the rock drilling process and ensure that the entire set of equipment is not damaged. At the same time, the two hydraulic lifting cylinders can assist in pulling out the drill rod stuck in the rock, without having to pull out the drill rod by lifting the guide rod frame 3, avoiding the need to increase the rated load of the lifting device 1 in order to pull out the drill rod, and reducing the cost of the lifting device 1.

[0042] Specifically, the hydraulic lifting cylinder may include a cylinder with a rodless chamber and a rod chamber, an air accumulator, a two-position three-way solenoid valve, a hydraulic oil circuit, an oil overflow circuit and an oil return line. The hydraulic oil circuit is provided with a one-way valve, a hydraulic pump and a filter, the oil return line is provided with a throttle valve, and the oil overflow circuit is provided with an overflow valve. The cylinder is set upside down, the upper part of the cylinder is a rod chamber, the lower part is a rodless chamber, and the lifting end (which can be a hydraulic rod) passing through the rod chamber is connected to the underwater module 2, and the lifting end extends away from the stabilizing leg 301. A throttle valve is set on the oil return line, which limits the speed of hydraulic oil reflux and plays a buffering role. Prevent the equipment from being damaged by excess impact energy during rock drilling.

[0043] The first end of the hydraulic oil circuit and the first end of the return oil pipeline are connected to the two-position three-way solenoid valve, and the oil tank is connected to the second end of the hydraulic oil circuit and the second end of the circuit pipeline. When the power unit just starts to drill rocks, the oil cylinder is in a fully retracted state, and the two-position three-way solenoid valve is controlled at the same time so that the hydraulic oil in the rod chamber of the oil cylinder can return to the oil tank. Then start the hydraulic impact hammer and start the rock drilling work until the drill rod of the hydraulic impact hammer drills into the rock surface to a designed depth, completing the single-point rock drilling. At this time, the hydraulic oil in the oil tank is injected into the rod chamber. At this time, the air in the rodless chamber is compressed and enters the accumulator (the accumulator only stores the compressed air). The volume of the rodless chamber increases, and the hydraulic lifting cylinder rises, thereby lifting the drill rod from the rock. This process completely relies on the guide rod frame 3 to support the ground to provide reaction force, and the object that lifts the guide rod frame 3 will not be subjected to adverse loads.

[0044] Optionally, in the process of pulling out the drill rod, in order to make the waterproof housing move along a fixed direction, at least one guide track 306 is further provided on the guide rod frame 3, one side of the guide track 306 is fixed inside the main frame, and the width of the guide track 306 matches the width of the clamping slot 201 outside the underwater module 2, so that the hydraulic lifting unit 305 drives the underwater module 2 to move along the guide track 306. The guide track 306 is arranged along the extension direction of the guide rod frame 3, and the guide track 306 is embedded in the clamping slot 201, so that the waterproof housing moves along the guide track 306. Among them, a groove can also be provided on the guide track 306, and a protrusion matching the groove can be provided on the waterproof housing.

[0045] Optionally, to prevent the waterproof housing from falling into the water due to a failure of the hydraulic lifting unit 305 , a limiting structure 304 is further provided at both ends of the guide track 306 . The limiting mechanism is used to abut against the card slot 201 outside the underwater module 2 .

[0046] In one embodiment, there are two guide rails 306, which are arranged on opposite sides of the waterproof housing. The limiting structure 304 is a limiting block, which abuts against the slot 201 outside the waterproof housing to place the power unit over the limiting structure 304. The outer size of the limiting block can be larger than the slot size of the slot 201.

[0047] Optionally, an air intake structure and a hydraulic oil transmission port are provided on the top of the waterproof shell. The hydraulic oil transmission port is connected to the hydraulic impact hammer. The air intake structure is connected to the cavity inside the waterproof shell. Compressed air enters the cavity inside the waterproof shell through the air intake structure to form a waterless environment.

[0048] In one embodiment, the air intake structure is a compressed air inlet valve, which is connected to the exhaust pipe of the air compressor, and controls whether the compressed air enters the waterproof housing through the compressed air inlet valve. The hydraulic oil transmission port is connected to the hydraulic oil pipe of the hydraulic pump, and the hydraulic impact hammer obtains hydraulic oil through the hydraulic oil transmission port.

[0049] Optionally, a stroke sensor is provided in the hydraulic lifting unit 305, and the stroke sensor is used to detect the rock drilling depth of the underwater module 2. The stroke sensor can detect the rock drilling depth of the drill rod, and after determining that the rock drilling depth reaches a predetermined value, send a rock drilling completion signal to a designated reporting object (such as a host computer that controls the underwater module 2), or send the rock drilling completion signal to the hydraulic lifting cylinder in the hydraulic lifting unit 305. After receiving the signal, the hydraulic lifting cylinder lifts the underwater module 2.

[0050] Optionally, at least one lifting lug 308 is further provided on the top of the main frame, through which a traction rope passes and is connected to the lifting device 1, and the lifting device 1 uses the traction rope to lift the guide rod frame 3. The lifting device 1 may be a crawler crane or other forms of cranes that can be used to lift the guide rod frame 3.

[0051] In one embodiment, there are four lifting lugs 308, and the lifting device 1 is connected to the lifting lugs 308 by four steel wire ropes of equal length, so as to hang the guide rod frame 3 and the equipment and accessories inside. Through the lifting and rotation of the lifting device 1, the guide rod frame 3 and the underwater module 2 inside the guide rod frame 3 are lifted to the position where rock drilling is required, and sunk to the bottom of the water until the drill rod of the hydraulic impact hammer is against the rock surface. At this time, whether the current lifting weight of the lifting device 1 is less than the wet weight of the equipment is used as a basis for judgment. If the lifting weight is less than the wet weight of the equipment, it is confirmed that it has been placed in the construction position.

[0052] The guide rod frame 3 used for hanging rock drilling in the present application includes a main frame, which is hollow in the main frame to form a cavity for movably fixing the underwater module 2, and the cavity is provided with an opening at the bottom of the guide rod frame 3, and the opening is used for allowing the rock drilling end of the underwater module 2 to extend for rock drilling. In the embodiment of the present application, the underwater module 2 is movably fixed in the main frame of the guide rod frame 3, and the rock drilling position of the underwater module 2 is limited by the guide rod frame 3, so as to effectively reduce the deviation of the rock drilling position, maintain the stability of the underwater module 2, improve the rock drilling effect, and can prevent the underwater module 2 from falling rapidly due to changes in the external environment, effectively reduce the impact load, and thus avoid the breakage of the traction rope or damage to the equipment.

[0053] Based on the same inventive concept, the present application also proposes a hanging rock drilling device, such as Figure 5 As shown, the suspended rock drilling equipment includes a lifting device 1, an underwater module 2 and a guide rod frame 3 for suspended rock drilling as described in the above embodiment; the underwater module 2 is fixed in the guide rod frame 3, and the lifting device 1 is connected to the guide rod frame 3 to lift and lower the guide rod frame 3.

[0054] Optionally, the lifting device 1 may be a crawler crane, a tower crane, a bridge crane, or other types of devices that can be used to lift the guide rod frame 3 to achieve underwater rock drilling.

[0055] In one embodiment, the lifting device 1 is a crane, the hydraulic lifting unit 305 is a hydraulic lifting cylinder, and the working process of the hanging rock drilling equipment includes: the underwater module 2 is installed in the guide rod frame 3, the crane lifts the guide rod frame 3, and puts the guide rod frame 3 into the rock drilling position at the bottom of the water. In the initial stage, the hydraulic lifting cylinder is shortened to the shortest stroke, the drill rod of the underwater module 2 is against the rock surface at the rock drilling position, the return oil pipeline connected to the rod chamber of the hydraulic lifting cylinder is opened, and the crane provides a certain pulling force to the guide rod frame 3. In the working state of the underwater module 2, the underwater module 2 drives the drill rod to drill the rock. As the depth of the drill rod entering the rock increases, the hydraulic lifting cylinder is pulled by the underwater module 2 and slides downward. During the rock drilling process, the crane keeps the position of the guide rod frame 3 unchanged. The travel sensor of the hydraulic lifting cylinder detects the rock penetration depth of the drill rod and transmits the detection result to the object (such as the host computer) that controls the crane, the guide rod frame 3 and the underwater module 2. After the object determines that the rock penetration depth reaches the preset depth, the crane stops providing tension, the guide rod frame 3 is inserted into the ground to support the underwater module 2, and after determining that the drill rod needs to be pulled out, the hydraulic lifting cylinder is activated to drive the underwater module 2 to rise and pull out the drill rod. If there is a next rock drilling position, the crane moves the guide rod frame 3 to the next rock drilling position.
