Technical Field

[0001] The present invention relates to the technical field of vehicle body support, and in particular to a rock drilling trolley support assembly and a hydraulic control system. Background Art

[0002] A drilling rig, also known as a drilling rig, is a type of rock drilling equipment specifically used for tunnels and underground projects. The drilling rig drilling method has the advantages of fast speed, automation, construction safety and high quality. In addition, it also has the advantage of a good tunnel excavation environment.

[0003] A rock drilling trolley with application number 201910032196.5 includes a chassis, a support adjustment device, a fine-adjustment device, a main adjustment device and a propulsion device. The support adjustment device is connected to the movable chassis, the main adjustment device is connected to the propulsion device, the fine-adjustment device is respectively connected to the main adjustment device and the chassis, and the chassis moves. The support adjustment device acts as a stabilizing balancing mechanism and assists in movement. The fine-adjustment device assists the main adjustment device to align the center point of the drilling eye on the working surface. However, during the use of the device, due to the soft soil, the support adjustment device will sink, making the use of the equipment unstable.

[0004] A rock drilling trolley with application number 202310696811.9 includes wheels, a frame, a drilling device and a first bracket, wherein the wheels are used to make the rock drilling trolley travel, the frame is used to install the wheels, the drilling device is used to drill holes in rocks, and the first bracket is used to support the drilling device. The first bracket is mounted on the frame. The rock drilling trolley also includes an anchor device and a second bracket, wherein the anchor device has an anchor embedded in or in contact with the rock, and the second bracket is arranged between the frame and the anchor device to transmit the force. The device will cause dust to fly during the walking process, thereby seriously affecting the construction environment.

[0005] Moreover, during the use of the equipment, if a collapse occurs in the rock cave and rocks roll down, the rocks may impact the vehicle body from the side end, which may easily cause damage to the supporting device. In addition, during the transportation of the equipment, the mass of the vehicle body is relatively large, and the crawler walking device at the bottom of the vehicle body may easily cause deformation of the load-bearing plate of the transport vehicle.

[0016] The present invention also provides a hydraulic control system for a rock drilling trolley support assembly, comprising the following steps:

[0017] Step 1: When the hydraulic control system detects that the side end of the equipment is impacted, the hydraulic control system controls the support rod of the supporting hydraulic cylinder on the impacted side of the equipment to retract, so that the equipment can resist the impact and reduce the damage to the equipment caused by the impact;

[0018] Step 2: When the equipment forms an anti-impact posture, the gravity of the equipment tends to the side that is impacted.

[0020] Step 4: When the equipment is removed from the site after use, the hydraulic control system controls the support rod of the supporting hydraulic cylinder to retract so that the support plate is flush with the middle of the crawler walking device. At this time, due to the situation in step 3, the first water channel and the second water channel are in a connected state. The hydraulic control system controls the water pump to start, so that the nozzle sprays water on the crawler walking device and the path to reduce the flying of dust;

[0021] Step 5. After the equipment is removed from the site, the hydraulic control system controls the hydraulic oil in the supporting hydraulic cylinder to flow back into the hydraulic control system, thereby increasing the hydraulic oil pressure in the cavity to exceed the pressure valve threshold, thereby causing the hydraulic oil in the cavity to flow back into the supporting hydraulic cylinder, causing the extension plate to retract into the supporting plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention is provided with components such as a hydraulic control system, a hydraulic cylinder, an extension plate and a pressure valve. When the hydraulic control system detects that the side end of the equipment is impacted, the hydraulic control system controls the support rod of the supporting hydraulic cylinder on the impacted side of the equipment to retract, so that the equipment can resist the impact and reduce the damage to the equipment caused by the impact. When the equipment is in an impact-resistant posture, the gravity of the equipment will tend to the impacted side. Therefore, the pressure valve corresponding to the supporting hydraulic cylinder on the impacted side will open due to the increase in hydraulic oil pressure, so that the extension plate is extended from the support plate to increase the support area of ​​the support plate, so that the impact-resistant posture of the equipment is more stable.

[0024] 2. The present invention is provided with components such as a hydraulic control system, a hydraulic cylinder, an extension plate and a pressure valve. During normal use of the equipment, when the hydraulic control system detects that the hydraulic oil pressure in the supporting hydraulic cylinder drops, the hydraulic control system determines that the supporting plate has sunk. At this time, the hydraulic control system controls the hydraulic oil in the supporting hydraulic cylinder to increase, so that the hydraulic oil pressure in the supporting hydraulic cylinder is greater than the threshold value of the pressure valve, thereby allowing the hydraulic oil to enter the cavity and the extension plate to extend from the supporting plate, so as to increase the supporting area of ​​the supporting plate and reduce the sinking of the supporting plate.

The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0035] Embodiment 1

[0036] like Figures 1 to 5 As shown, a rock drilling trolley support assembly of the present invention includes a vehicle body 1, a cab 2, a crawler walking device 3, a support device 4 and a mechanical arm 5, and is characterized in that an operating table 6 is rotatably provided on the mechanical arm 5, the operating table 6 is arranged at the end of the mechanical arm 5, and the support device 4 is arranged at the front and rear sides of the vehicle body 1, and the operator can sit in the cab 2 to operate the equipment, the crawler walking device 3 is used to control the movement of the equipment, so that the mechanical arm 5 can be better used, and the drilling assembly on the mechanical arm 5 can drill holes in the wall. Then, the worker stands on the operating table 6 to put explosives into the holes in the wall to prepare for subsequent blasting, and after the vehicle body 1 stops, the vehicle body 1 is supported and stabilized with the assistance of the support device 4, so that the equipment is more stable when drilling holes in the wall, thereby improving the stability of the equipment.

[0037] The supporting device 4 includes a connecting device 7 and a supporting hydraulic cylinder 401. The connecting device 7 is arranged on the vehicle body 1, and the supporting hydraulic cylinder 401 is arranged on both sides of the connecting device 7. A connecting plate 402 is arranged at the output end of the supporting hydraulic cylinder 401, and a supporting plate 403 is arranged at the lower end of the connecting plate 402. The connecting device 7 is used to connect and fix the supporting device 4 to the vehicle body 1, so that the supporting device 4 is more stable when in use. With the assistance of the supporting hydraulic cylinder 401, the connecting plate 402 can be lifted and lowered with the supporting plate 403, so that the supporting plate 403 can support the vehicle body 1 after contacting the ground, so that the vehicle body 1 is more stable during use.

[0038] The connecting device 7 includes a connecting plate 701, and a plug plate 702 is provided on the side of the connecting plate 701 close to the vehicle body 1. A circular hole 703 is provided on the plug plate 702. The plug plate 702 is inserted into the corresponding position of the side end of the vehicle body 1. A through hole 704 is provided in the connecting plate 701, and the through hole 704 is square. After the plug plate 702 is inserted into the corresponding position of the side end of the vehicle body 1, the anchor rod for fixing is inserted into the circular hole 703, so that the plug plate 702 is connected and fixed to the vehicle body 1, so that the connecting device 7 is fixed to the side end of the vehicle body 1, and there are two circular holes 703. Therefore, after the connecting device 7 is fixed to the side end of the vehicle body 1, the connecting device 7 will not deflect, so that the connecting device 7 is more stable when used.

[0039] A square plate 705 is arranged in the through hole 704, and mounting frames 706 are arranged on both sides of the square plate 705. Mounting plates 413 are arranged at the upper and lower ends of the supporting hydraulic cylinder 401, and the mounting plates 413 are fixed on the mounting frames 706. The supporting rod 410 at the output end of the supporting hydraulic cylinder 401 passes through the mounting frame 706, and the square plate 705 passes through the through hole 704, and then the supporting hydraulic cylinder 401 is arranged on both sides of the square plate 705. After the supporting hydraulic cylinder 401 is started, the output end of the supporting hydraulic cylinder 401 will drive the supporting rod 410 to move, thereby moving the supporting plate 403. After the supporting plate 403 contacts the ground, the vehicle body 1 is propped up under the action of the reverse force, so that the equipment is more stable when drilling holes in the wall, thereby improving the stability of the equipment.

[0040] Both the connecting plate 701 and the square plate 705 are provided with mounting holes 707, and the mounting holes 707 on the connecting plate 701 correspond to the mounting holes 707 on the square plate 705. The connecting plate 701 is provided with a fixing plate 708, and the fixing plate 708 is set on the vehicle body 1 through fixing bolts. After the square plate 705 is inserted into the through hole 704, the mounting holes 707 on the connecting plate 701 correspond to the mounting holes 707 on the square plate 705, and then the fixing anchor rods are inserted into the mounting holes 707 on the connecting plate 701 and the square plate 705, so that the square plate 705 and the connecting plate 701 are connected and fixed, so that the supporting device 4 is more stable during use.

[0041] When the equipment is in use, the driver enters the cab 2 and controls the equipment to move with the assistance of the crawler walking device 3. After the equipment moves to the position, the supporting devices 4 around the vehicle body 1 start to operate, thereby supporting the equipment stably and ensuring that the equipment is more stable when drilling holes in the wall.

[0042] When the supporting device 4 is in operation, the supporting hydraulic cylinder 401 is started, and the output end of the supporting hydraulic cylinder 401 is lifted and lowered with the supporting plate 403 through the connecting plate 402, so that the supporting plate 403 contacts the ground, thereby propping up the vehicle body 1, making the equipment more stable when punching holes in the wall, avoiding the vibration generated by the equipment during punching and causing the equipment to shake, thereby improving the stability of the equipment.

[0043] After the equipment is fixed, the driver controls the robot arm 5 in the cab 2 to make the drilling assembly at the end of the robot arm 5 close to the wall, and drills the rock wall with the assistance of the drilling assembly. After the holes on the entire wall are processed, the driver controls the robot arm 5 in the cab 2 to make the operating table 6 close to the ground, and then the worker enters the operating table 6. With the assistance of the robot arm 5, the operating table 6 brings the worker to the hole in the wall. At this time, the worker can put the explosives into the hole in the wall to prepare for subsequent blasting. After the explosives are arranged, the worker on the operating table 6 is sent back to the ground with the assistance of the robot arm 5, and then the equipment retracts the support device 4 and evacuates with the assistance of the crawler walking device 3. After the equipment and the workers have evacuated, the wall begins to be blasted to achieve the effect of rock drilling.

[0044] During the use of the equipment, if the cave collapses and causes the rocks to roll down, the rocks will impact the body 1 from the side end of the body 1, which may easily cause damage to the support device 4. In addition, during the transportation of the equipment, the body 1 has a large mass, and the crawler walking device 3 at the bottom of the body 1 may easily cause deformation of the load-bearing plate of the transport vehicle. At the same time, after the equipment is used, when the equipment is withdrawn from the cave, a large amount of mud will adhere to the crawler walking device 3 at the bottom of the body 1. After the equipment is moved out of the cave, it needs to be manually washed, which is time-consuming and labor-intensive. Therefore, the following solutions are proposed:

[0045] like Figures 1 to 7As shown, an extension plate 404 is slidably provided on the outer side of the support plate 403, and a nozzle 405 is provided on the side end of the extension plate 404. A cavity 406 is provided in the connection plate 402, and the extension plate 404 slides in the cavity 406. A piston plate 407 is provided on one side of the extension plate 404 located in the cavity 406. A first water channel 408 is provided on the connection plate 402, and a second water channel 409 is provided on the extension plate 404. The second water channel 409 is connected to the nozzle 405. After the extension plate 404 extends out from the support plate 403, the support plate 403 is The supporting area is increased, thereby making the support of the support plate 403 more stable, and when the extension plate 404 is extended from the support plate 403, the first water channel 408 is connected with the second water channel 409, and after the first water channel 408 is connected with the second water channel 409, the water in the first water channel 408 is sprayed out by the nozzle 405 through the second water channel 409, and the water sprayed by the nozzle 405 can wash the crawler walking device 3, and the water sprayed by the nozzle 405 can wet the walking path of the crawler walking device 3 to reduce the raising of dust.

[0046] A support rod 410 is provided at the output end of the support hydraulic cylinder 401, and a connecting plate 402 is provided at the lower end of the support rod 410. An oil passage is provided in the support rod 410, and a cavity 406 is connected with the support hydraulic cylinder 401 through the oil passage. A pressure valve is provided in the oil passage. After the support hydraulic cylinder 401 is started, the output end of the support hydraulic cylinder 401 drives the support rod 410 to rise and fall. When the support rod 410 rises and falls, the support plate 403 is driven to move through the connecting plate 402, so that the support plate 403 is lowered to contact the ground for support. In the process of supporting the support plate 403, if the pressure of the hydraulic oil in the support hydraulic cylinder 401 is greater than the threshold value of the pressure valve, the pressure valve will open, and the hydraulic oil in the support hydraulic cylinder 401 will enter the cavity 406, and with the assistance of the hydraulic oil, the piston plate 407 will be pushed to move, so that the extension plate 404 is extended from the support plate 403, so that the support area of ​​the support plate 403 is increased, and the support force per unit area of ​​the support plate 403 is reduced, thereby improving the stability of the equipment.

[0047] A fixing hole 411 is provided on the connecting plate 402 and the supporting plate 403, and a countersunk hole 412 is provided at the bottom end of the supporting plate 403. The fixing hole 411 matches the countersunk hole 412. A fixing bolt is provided in the countersunk hole 412. A fixing nut is provided in the countersunk hole 412. The fixing bolt and the fixing nut cooperate with each other. The fixing holes 411 on the connecting plate 402 and the supporting plate 403 are provided with fixing bolts and fixing nuts. Therefore, the connecting plate 402 and the supporting plate 403 are connected and fixed by fixing bolts and fixing nuts, making it more stable during use.

[0048] A water tank is arranged in the vehicle body 1, and the first water channel 408 is connected to the water tank through a water pipe. A water pump is arranged on the water pipe. The water tank is arranged at the side end of the connecting device 7. After the pressure valve is opened, the water pump will also be started. At this time, under the action of the water pump, the water in the water tank enters into the first water channel 408. In the process that the extension plate 404 is extended from the support plate 403, the first water channel 408 will be connected with the second water channel 409, and then, the water in the first water channel 408 will enter into the second water channel 409, and the water in the second water channel 409 will be sprayed out through the nozzle 405. The water sprayed out by the nozzle 405 can flush the crawler walking device 3.

[0049] During use of the present invention, with the assistance of the supporting hydraulic cylinder 401 of the supporting device 4, the supporting plate 403 contacts the ground, so that the supporting device 4 supports the device, making the equipment more stable when drilling holes in the wall. When falling rocks roll in the cave and are about to hit the vehicle body 1, the hydraulic control system of the equipment will control the support rod 410 at the output end of the supporting hydraulic cylinder 401 on the impacted side to retract, so that the height of the vehicle body 1 on the impacted side is reduced, so that when the falling rocks roll and hit the vehicle body 1, the impacted side of the vehicle body 1 is lowered, thereby achieving the effect of protecting the vehicle body 1.

[0050] When the impacted side of the vehicle body 1 descends, the weight of the vehicle body 1 will also tilt toward the impacted side, so the pressure on the support plate 403 on the impacted side will increase, and the pressure of the hydraulic oil in the support hydraulic cylinder 401 on the impacted side will also increase. When the inclination of the vehicle body 1 reaches the set value, the pressure of the hydraulic oil in the support hydraulic cylinder 401 on the impacted side will also increase and exceed the threshold of the pressure valve, so the pressure valve will be opened. After the pressure valve is opened, the hydraulic oil in the support hydraulic cylinder 401 will enter the cavity 406, and then the piston plate 407 will move through the push of the hydraulic oil. The movement of the piston plate 407 will cause the extension plate 404 to extend out of the support plate 403, thereby increasing the support area of ​​the support plate 403, thereby reducing the support force per unit area of ​​the support plate 403, thereby protecting the support device 4 and improving the stability of the equipment.

[0051] During normal use of the support device 4, when the equipment is drilling a hole in the wall, the equipment will vibrate, and the support plate 403 will easily sink with the help of the vibration, so that the vehicle body 1 will descend, and as the vehicle body 1 descends, the lower end of the crawler walking device 3 will contact the ground. At this time, with the vibration of the equipment, the vehicle body 1 is likely to move slightly, which is likely to cause a safety accident. As the support plate 403 sinks and the lower end of the crawler walking device 3 contacts the ground, the supporting force of the entire equipment will be borne by the support device 4 and the crawler walking device 3. Therefore, the liquid in the supporting hydraulic cylinder 401 The pressure of the pressurized oil will decrease, and when the hydraulic control system detects this phenomenon, the hydraulic control system will keep the supporting hydraulic cylinder 401 running, allowing more hydraulic oil to enter the supporting hydraulic cylinder 401, so that the pressure of the hydraulic oil in the supporting hydraulic cylinder 401 exceeds the threshold of the pressure valve, thereby opening the pressure valve. After the pressure valve opens, the hydraulic oil in the supporting hydraulic cylinder 401 will enter the cavity 406, so that the extension plate 404 extends out from the supporting plate 403, thereby increasing the supporting area of ​​the supporting plate 403 to reduce the sinking of the supporting plate 403 and ensure the stability of the equipment.

[0052] After the drilling of the wall is completed and the explosives are placed, when the equipment needs to evacuate the cave, the hydraulic control system controls the support rod 410 supporting the hydraulic cylinder 401 to retract, and the support plate 403 will move upward. At this time, the extension plate 404 is in an extended state, so the first water channel 408 and the second water channel 409 are in a connected state. After the support rod 410 supporting the hydraulic cylinder 401 is retracted, the hydraulic control system starts the water pump. At this time, under the action of the water pump, the water in the water tank enters the first water channel 408. In the process of the extension plate 404 being extended from the support plate 403, the first water channel 408 will be connected with the second water channel 409, and then the water in the first water channel 408 will enter the second water channel 4 09, the water in the second water channel 409 is sprayed out through the nozzle 405. The water sprayed out by the nozzle 405 can wash the crawler walking device 3, so that the crawler walking device 3 is more stable when in use, and the nozzle 405 will also spray water on the walking path of the crawler walking device 3, so as to reduce the flying of dust during the use of the crawler walking device 3. After the equipment leaves the cave, the hydraulic control system controls the hydraulic oil in the supporting hydraulic cylinder 401 to continue to flow back to the hydraulic control system, so that the hydraulic oil pressure in the cavity 406 is greater than the pressure valve, so that the hydraulic oil in the cavity 406 flows back to the supporting hydraulic cylinder 401, so that the extension plate 404 is retracted into the support plate 403.

[0053] When the equipment is transported by a transport vehicle, the equipment will be moved to the frame of the transport vehicle with the assistance of the crawler walking device 3. At this time, when the equipment is only supported by the crawler walking device 3, the protruding part of the lower end of the crawler walking device 3 is easy to compress and deform the frame of the transport vehicle. Therefore, when the equipment is transported, the hydraulic control system controls the support rod 410 supporting the hydraulic cylinder 401 to extend, so that the support plate 403 and the crawler walking device 3 jointly bear the weight of the equipment, so as to reduce the damage of the crawler walking device 3 to the transport vehicle, and also increase the contact area between the equipment and the transport vehicle, so that the equipment is more stable during transportation.

[0054] Embodiment 2

[0055] The present invention also provides a hydraulic control system for a rock drilling trolley support assembly, the hydraulic control system comprising the following steps:

[0056] Step 1: When the hydraulic control system detects that the side end of the equipment is impacted, the hydraulic control system controls the support rod 410 of the supporting hydraulic cylinder 401 on the impacted side of the equipment to retract, so that the equipment can resist the impact and reduce the damage to the equipment caused by the impact;

[0057] Step 2: When the device forms an anti-impact posture, the gravity of the device tends to the side that is impacted, so the pressure valve corresponding to the supporting hydraulic cylinder 401 on the side that is impacted will open due to the increase in hydraulic oil pressure, so that the extension plate 404 extends out from the supporting plate 403 to increase the supporting area of ​​the supporting plate 403, making the device's anti-impact posture more stable;

[0058] Step 3: During normal use of the equipment, when the hydraulic control system detects that the hydraulic oil pressure in the supporting hydraulic cylinder 401 drops, the hydraulic control system determines that the supporting plate 403 has sunk. At this time, the hydraulic control system controls the hydraulic oil in the supporting hydraulic cylinder 401 to increase, so that the hydraulic oil pressure in the supporting hydraulic cylinder 401 is greater than the threshold of the pressure valve, so that the hydraulic oil enters the cavity 406, and the extension plate 404 extends from the supporting plate 403, so as to increase the supporting area of ​​the supporting plate 403 and reduce the sinking of the supporting plate 403;

[0059] Step 4: When the equipment is removed from the site after use, the hydraulic control system controls the support rod 410 supporting the hydraulic cylinder 401 to retract, so that the support plate 403 is flush with the middle of the crawler walking device 3. At this time, due to the situation in step 3, the first water channel 408 and the second water channel 409 are in a connected state, and the hydraulic control system controls the water pump to start, so that the nozzle 405 sprays water on the crawler walking device 3 and the path to reduce the flying of dust;

[0060] Step 5. After the equipment is removed from the site, the hydraulic control system controls the hydraulic oil in the supporting hydraulic cylinder 401 to flow back into the hydraulic control system, thereby increasing the hydraulic oil pressure in the cavity 406 to exceed the pressure valve threshold, thereby causing the hydraulic oil in the cavity 406 to flow back into the supporting hydraulic cylinder 401, causing the extension plate 404 to retract into the supporting plate 403.

[0061] The main functions achieved by the present invention are: by setting up components such as an extension plate 404, a hydraulic control system, a pressure valve and a water pump, when the side end of the vehicle body 1 is impacted, the impacted side of the vehicle body 1 is controlled to descend to form an impact-resistant posture through the control of the hydraulic control system, so as to reduce the impact damage to the equipment, and through the coordination of the hydraulic control system and the pressure valve, the extension plate 404 is extended from the support plate 403 to increase the area of ​​the support plate 403, thereby improving the stability of the equipment use, and when the equipment is removed from the site, by starting the water pump, the water sprayed from the nozzle 405 can clean the crawler walking device 3, and the nozzle 405 can also spray water on the path, thereby reducing the flying of dust when the equipment moves.
