Description

Tunnel ventilation pipe hoisting device and its application Technical Field

[0001] This invention belongs to the field of tunnel construction. More specifically, this invention relates to a tunnel ventilation and water pipe winch device and its application. Background Technology

[0002] In tunnel construction, pneumatic drills are used to drill blast holes at the tunnel face. These drills require compressed air, necessitating the use of a high-pressure air duct (approximately 200mm in diameter) to supply compressed air from outside the tunnel to the tunnel face. To prevent damage to the high-pressure air duct from the shockwave during blasting, it is typically positioned approximately 50 meters from the tunnel face. Compressed air from the high-pressure air duct is then transported to the tunnel face via a water-air duct (approximately 50mm in diameter) to facilitate drilling. As the tunnel face advances, the water-air duct needs to be moved along with it. However, the distance between the tunnel face and the high-pressure air duct is considerable (approximately 50 meters), and the presence of multiple water-air ducts, many of which are large in diameter and heavy, makes manual dragging of the ducts extremely labor-intensive and inefficient. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0004] One object of the present invention is to provide a tunnel ventilation pipe winch device, which can use compressed air in a high-pressure ventilation pipe to drive the rotation of a drum, thereby enabling the ventilation pipe to be wound around the drum or the ventilation pipe wound around the drum to be unwound.

[0005] To achieve these objectives and other advantages of the present invention, a tunnel ventilation pipe hoisting device is provided, comprising:

[0006] Support base;

[0007] A roller is rotatably mounted on the support base. End plates are fixedly mounted on both ends of the roller to define a sealed cavity on the roller. An exhaust valve is provided at the end of the roller.

[0008] A pneumatic device includes a fixed shaft and a guide plate. The fixed shaft passes through the roller and the end plates at both ends. The fixed shaft is rotatably connected to the end plates and to a support base. The guide plate has a spiral structure and is fixedly mounted on the fixed shaft. The edge of the guide plate abuts against the inner wall of the roller. The end of the fixed shaft has a hollow tubular structure and a through hole to allow the interior of the shaft to communicate with a sealed cavity. A first locking structure is provided between the end plates and the support base, a second locking structure is provided between the fixed shaft and the support base, and a third locking structure is provided between the end plates and the fixed shaft.

[0009] The connecting pipe has one end connected to the fixed shaft via an adapter, and the other end connected to the high-pressure ventilation duct in the tunnel to introduce compressed air from the high-pressure ventilation duct into the sealed cavity to drive the drum to rotate.

[0010] When the drum needs to rotate, the first locking structure and the second locking structure open, the third locking structure closes, and compressed air is introduced through the connecting pipe, causing the fixed shaft to drive the drum to rotate together.

[0011] When the roller does not need to rotate but the fixed shaft needs to rotate, the first locking structure is closed, and the second and third locking structures are opened. Compressed air is introduced through the connecting pipe, the roller remains stationary, and the fixed shaft can rotate relative to the roller.

[0012] Preferably, graphite strips are provided at the edge of the air guide plate.

[0013] Preferably, a lubrication mechanism is provided at the edge of the air guide plate, the lubrication mechanism comprising:

[0014] The mounting groove is spirally arranged on the air guide plate, and the opening of the mounting groove is located at the edge of the air guide plate.

[0015] A graphite strip is disposed at the edge of the air guide plate to close the opening of the mounting groove. The graphite strip abuts against the inner wall of the roller. An oil guide hole is provided on the graphite strip to allow the mounting groove to communicate with the sealed cavity.

[0016] An oil pressure bar is set in the mounting groove. Several springs are set between the mounting groove and the oil pressure bar. The mounting groove between the oil pressure bar and the graphite bar is filled with lubricating grease. Several air guide holes are set on the air guide plate between the oil pressure bar and the bottom of the mounting groove so that the mounting groove can communicate with the sealed cavity.

[0017] When compressed air is introduced into the sealed cavity, the compressed air pushes the oil pressure bar to move along the edge of the air guide plate to discharge the lubricating grease in the mounting groove through the oil guide hole to lubricate the contact point between the graphite strip and the inner wall of the roller; after the compressed air is stopped, the contraction of the spring drives the oil pressure bar to move towards the bottom of the mounting groove so that a negative pressure is formed in the mounting groove between the oil pressure bar and the graphite strip to collect the lubricating grease back into the mounting groove.

[0018] Preferably, the air guide plate between the graphite strip and the oil pressure strip is provided with several lubricating grease filling holes, and a sealing element is provided at the filling hole.

[0019] Preferably, the air guide plate is provided with several baffles, and the baffles are located in the screw grooves formed by the air guide plate.

[0020] Preferably, a power generation device is provided on the support base, and the power generation device is connected to the fixed shaft.

[0021] Preferably, the connecting pipe is equipped with an electrically controlled speed regulating valve.

[0022] Preferably, it also includes a control device, wherein the control valve is an electrically controlled exhaust valve, and the control device is electrically connected to the electrically controlled speed control valve and the electrically controlled exhaust valve.

[0023] A method for hoisting a ventilation and water pipe using the aforementioned tunnel ventilation and water pipe hoisting device includes the following steps:

[0024] 1) Move the device to the front of the working face, and connect the device to the high-pressure air duct through a drive air duct with a diameter of 15-25mm;

[0025] 2) Fix a steel wire rope on the drum, and fix the other end of the steel wire rope to a water pipe with a diameter of 50-100mm.

[0026] 3) The first and second locking structures are opened, and the third locking structure is closed. Compressed air is introduced through the connecting pipe, and the fixed shaft drives the drum to rotate together. The wire rope is wound around the drum, thereby pulling the air and water pipe to the front of the working face to meet the construction needs.

[0027] 4) After construction, fix the air pipe on the roller, and introduce compressed air through the connecting pipe. The fixed shaft drives the roller to rotate together to wind the air pipe on the roller.

[0028] A method for providing power using the aforementioned tunnel ventilation pipe winch device involves closing the first locking structure and opening the second and third locking structures. Compressed air is introduced through a connecting pipe, the drum remains stationary, and the fixed shaft can rotate relative to the drum. The fixed shaft is connected to a power generation device so that the rotation of the fixed shaft drives the power generation device to generate electricity.

[0029] The present invention has at least the following beneficial effects:

[0030] First, the device of the present invention can use compressed air provided by the high-pressure air duct to drive the drum to rotate, so as to realize the hoisting of the air duct, reduce the manpower required to drag the air duct, and improve the dragging efficiency of the air duct.

[0031] Secondly, the device of the present invention can achieve forward or reverse rotation of the drum by introducing compressed air into different fixed shaft ends.

[0032] Third, when compressed air is introduced into the device of the present invention, the airflow drives the fixed shaft and the drum to rotate, thereby winding the water pipe around the drum or pulling the water pipe. When the device is needed to generate electricity or drive external equipment, the first locking structure closes, and the second and third locking structures open. When compressed air is introduced, the compressed air drives the fixed shaft to rotate, while the drum remains stationary. This method reduces the weight of the rotating parts. That is, when the water pipe is wound on the drum, the rotatable parts include the water pipe, the drum, the air guide plate, and the fixed shaft, making the rotatable parts relatively heavy and requiring a large amount of compressed air pressure to drive them. By designing the drum and fixed shaft to be rotatable, when the device needs to drive external equipment to rotate, such as driving a generator to generate electricity, the drum can remain stationary relative to the support, with only the fixed shaft rotating. This greatly reduces the weight of the rotatable parts, allowing the fixed shaft to rotate under the action of lower compressed air pressure, reducing the high requirements for compressed air pressure and improving the utilization efficiency of compressed air.

[0033] Fourth, the device of the present invention, by setting graphite strips at the edge of the air guide plate, ensures that when the drum rotates relative to the air guide plate, the graphite strips contact the inner wall of the drum, thus avoiding wear of the air guide plate caused by direct contact between the air guide plate and the drum. Furthermore, after compressed air is introduced into the sealed cavity, the compressed air can enter the mounting groove through the air guide hole, driving the oil pressure strip to move towards the opening of the mounting groove to discharge the lubricating grease in the mounting groove through the oil guide hole, thereby lubricating and sealing the gap between the graphite strips and the inner wall of the drum.

[0034] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0046] As shown in Figures 1-7, the present invention provides a tunnel ventilation pipe hoisting device, which includes:

[0047] A tunnel ventilation pipe hoisting device, comprising:

[0048] Support 1;

[0049] Roller 2 is rotatably mounted on the support base 1. End plates are provided at both ends of roller 2 to define a sealed cavity on roller 2. An exhaust valve 3 is provided at the end of roller 2.

[0050] A pneumatic device includes a fixed shaft 6 and a guide plate 7. The fixed shaft 6 passes through the roller 2 and the end plates at both ends. The fixed shaft 6 is rotatably connected to the end plates and rotatably connected to the support base 1. The guide plate 7 has a spiral structure and is fixedly mounted on the fixed shaft 6. The edge of the guide plate 7 abuts against the inner wall of the roller 2. The end of the fixed shaft 6 has a hollow tubular structure and a through hole 9 to allow the interior of the shaft to communicate with a sealed cavity. A first locking structure is provided between the end plate and the support base 1, a second locking structure is provided between the fixed shaft 6 and the support base 1, and a third locking structure is provided between the end plate and the fixed shaft.

[0051] The connecting pipe has one end connected to the fixed shaft 6 via an adapter, and the other end of the connecting pipe is connected to the high-pressure ventilation pipe in the tunnel to introduce compressed air from the high-pressure ventilation pipe into the sealed cavity to drive the roller 2 to rotate.

[0052] When the roller 2 needs to rotate, the first locking structure and the second locking structure open, the third locking structure closes, and compressed air is introduced through the connecting pipe, causing the fixed shaft 6 to drive the roller 2 to rotate together.

[0053] When the roller 2 does not need to rotate but the fixed shaft 6 needs to rotate, the first locking structure is closed, and the second and third locking structures are opened. Compressed air is introduced through the connecting pipe, the roller 2 remains stationary, and the fixed shaft 6 can rotate relative to the roller 2.

[0054] In this technical solution, the support base 1 may include two support frames, both of which are A-shaped, and the two support frames are connected by a connecting rod. The end plate is fixedly connected to the inner wall of the roller 2, and a first bearing 4 is provided in the middle of the end plate. A fixed shaft 6 passes through the first bearing 4 to realize the relative movement between the end plate and the fixed shaft 6. The fixed shaft 6 is rotatably mounted on the support frame through a second bearing 5. The air guide plate 7 may be located in the middle of the roller 2, or at the end of the roller 2, or along the entire length of the roller 2. The first locking structure may be a locking method using a connecting shaft and a connecting ear. Specifically, a first connecting ear is provided on the support base 1, and a second connecting ear is provided on the end plate. The first connecting shaft passes through the first connecting ear and the second connecting ear to keep the roller 2 in a locked state. When the roller 2 needs to rotate relative to the support base 1, the first connecting shaft can be pulled out. The second locking structure can also lock the connection between the connecting shaft and the connecting ear. Specifically, a third connecting ear is provided on the support base 1, and a fourth connecting ear is provided on the fixed shaft 6. The second connecting shaft passes through the third and fourth connecting ears to lock the fixed shaft 6. The third locking structure can also lock the connection between the connecting shaft and the connecting ear. Specifically, a fifth connecting ear is provided on the end plate, and a sixth connecting ear is provided on the fixed shaft. The third connecting shaft passes through the fifth and sixth connecting ears to lock the roller and the fixed shaft. When only the fixed shaft 6 needs to rotate to drive the external equipment, the first locking structure fixes the roller 2 to the support base 1, and the second and third locking structures are opened to allow the fixed shaft 6 to rotate relative to the support base 1 and the roller. When compressed air is introduced into the fixed shaft 6, the compressed air pushes the fixed shaft 6 to rotate to drive the external equipment.

[0055] In use, if the roller 2 needs to rotate forward, the connecting pipe is connected to the right end of the fixed shaft 6, and compressed air enters the roller 2 from the right end. At this time, the exhaust valve 3 at the right end plate of the roller 2 is closed, and the exhaust valve 3 at the left end plate of the roller 2 is open. Compressed air flows from the right end to the left end of the roller 2, realizing the forward rotation of the roller 2. If the roller 2 needs to rotate in reverse, the connecting pipe is connected to the left end of the fixed shaft 6, and compressed air enters the roller 2 from the left end. At this time, the exhaust valve 3 at the left end plate of the roller 2 is closed, and the exhaust valve 3 at the right end plate of the roller 2 is open. Compressed air flows from the left end to the right end of the roller 2, realizing the reverse rotation of the roller 2.

[0056] In another technical solution, the support base includes two H-shaped brackets and at least one folding rod 21. The upper ends of the two H-shaped brackets are hinged, and the two ends of the folding rod 21 are respectively hinged to the middle of the two H-shaped brackets. The folding rod 21 includes a first folding rod 21 and a second folding rod 21, with the ends of the first and second folding rods 21 hinged away from the H-shaped brackets. The upper part of the H-shaped brackets is hinged, and the folding rod 21 is hinged to the H-shaped brackets and to the middle of the folding rod 21, so that the support base can be folded towards the middle to reduce the volume of the device when not in use, facilitating storage and transportation. In some specific solutions, the tops of the two H-shaped brackets are hinged to the connecting part 17, and the fixed shaft is rotatably mounted on the connecting part 17.

[0057] In another technical solution, the H-shaped bracket is provided with at least a pair of fixing rods. One end of the first fixing rod 20 is hinged to the lower end of the H-shaped bracket so that the first fixing rod 20 can rotate upward to a position parallel to the H-shaped bracket. The other end of the second fixing rod 18 is hinged to the upper end of the H-shaped bracket so that the second fixing rod 18 can rotate downward to a position parallel to the H-shaped bracket. The free ends of both the first fixing rod 20 and the second fixing rod 18 are provided with connecting plates 19, and the connecting plates 19 are provided with connecting holes. In use, the fixing rods are rotated to form an angle with the H-shaped bracket, and expansion bolts on the tunnel wall pass through the connecting holes and connect with nuts, thereby fixing the device to the tunnel wall.

[0058] In another technical solution, discs 15 are provided at both ends of the roller to prevent the water pipe from being squeezed out from the ends of the roller.

[0059] In another technical solution, a graphite strip 10 is provided at the edge of the air guide plate 7. In this technical solution, the graphite strip 10 is provided along the edge of the air guide plate 7 so that the graphite strip 10 abuts against the fixed shaft 6, so as to utilize the tribological properties of the graphite strip 10 to protect the edge of the air guide plate 7 and the fixed shaft 6 from friction and wear.

[0060] In another technical solution, a lubrication mechanism is provided at the edge of the air guide plate 7, the lubrication mechanism comprising:

[0061] The mounting groove 14 is spirally arranged on the air guide plate 7, and the opening of the mounting groove 14 is located at the edge of the air guide plate 7.

[0062] A graphite strip 10 is disposed at the edge of the air guide plate 7 to close the opening of the mounting groove 14. The graphite strip 10 abuts against the inner wall of the roller 2. An oil guide hole 11 is provided on the graphite strip 10 to allow the mounting groove 14 to communicate with the sealed cavity.

[0063] The oil pressure bar 12 is disposed in the mounting groove 14. Several springs 13 are disposed between the mounting groove 14 and the oil pressure bar 12. The mounting groove 14 between the oil pressure bar 12 and the graphite bar 10 is filled with lubricating grease. Several air guide holes are provided on the air guide plate 7 between the oil pressure bar 12 and the bottom of the mounting groove 14 so that the mounting groove 14 communicates with the sealed cavity.

[0064] When compressed air is introduced into the sealed cavity, the compressed air pushes the oil pressure strip 12 to move along the edge of the air guide plate 7 to discharge the lubricating grease in the mounting groove 14 through the oil guide hole 11 to lubricate the contact between the graphite strip and the inner wall of the roller 2; after the compressed air is stopped, the contraction of the spring 13 drives the oil pressure strip 12 to move towards the bottom of the mounting groove 14 so that a negative pressure is formed in the mounting groove 14 between the oil pressure strip 12 and the graphite strip 10 to collect the lubricating grease back into the mounting groove 14.

[0065] In this technical solution, the pressure bar 12 is made of a rigid material and has a spiral structure. Compressed air enters the mounting groove 14 through the air guide hole, pushing the pressure bar 12 to move in the mounting groove 14 and towards the groove opening of the mounting groove 14, so as to squeeze the lubricating grease in the mounting groove 14 through the oil guide hole 11 and enter the gap between the graphite strip 10 and the inner wall of the roller 2, which further lubricates the graphite strip 10 and the inner wall of the roller 2. The lubricating grease in the gap between the graphite strip 10 and the inner wall of the roller 2 also plays a certain sealing role, so that the airflow can only flow along the direction of the guide plate, thereby improving the effective utilization rate of compressed air.

[0066] In another technical solution, a slot is provided at the edge of the air guide plate 7, and a connector is provided on the graphite strip 10. The connector is slidably inserted into the slot. One end of the spring is connected to the connector, and the other end is fixedly connected to the wall of the mounting groove 14, so that the graphite strip 10 is ejected from the slot by the spring, making the graphite strip 10 tightly abut against the inner wall of the roller 2. After the device has been running for a long time, the wear of the graphite strip 10 will increase the gap between the graphite strip 10 and the inner wall of the roller 2. This technical solution uses the elasticity of the spring to eject the graphite strip 10 from the slot, so that the graphite strip 10 is always tightly connected to the inner wall of the roller 2, preventing compressed air from flowing through the gap between the graphite strip 10 and the inner wall of the roller 2, thereby improving the efficiency of the compressed air driving the fixed shaft 6 to rotate.

[0067] In another technical solution, the air guide plate 7 between the graphite strip 10 and the oil pressure strip 12 is provided with several lubricating grease filling holes, and a sealing element is provided at the filling hole. As the lubricating grease in the mounting groove 14 decreases, lubricating grease can be added through the filling holes to meet the continuous lubrication requirements of the device.

[0068] In another technical solution, the air guide plate 7 is provided with several baffles 8, which are located in the screw grooves formed by the air guide plate 7. By setting the baffles 8, the obstruction effect of the airflow is increased, and the kinetic energy of the airflow is better converted into the kinetic energy of the roller 2.

[0069] In another technical solution, a power generation device is installed on the support base 1, and the power generation device is connected to the fixed shaft 6. Specifically, a pulley 16 can be installed on the fixed shaft 6, and the power generation device is connected to the inclined pulley via a belt so that the rotation of the fixed shaft 6 drives the power generation device to generate electricity, meeting the power demand when there is a sudden power outage during the construction face.

[0070] In another technical solution, a storage battery is also installed on the support base 1, and the power generation device is connected to the storage battery to charge it. During tunnel construction, if not all gas-using construction projects are carried out, resulting in the compressed air supply from the high-pressure ventilation duct exceeding the current project's gas consumption, the compressed air is used to drive the fixed rotating device to generate electricity, which is then stored in the storage battery to improve the utilization rate of compressed air.

[0071] In another technical solution, an electrically controlled speed regulating valve is provided on the connecting pipe. In this technical solution, the magnitude of the compressed air flow entering the drum 2 is controlled by adjusting the electrically controlled speed regulating valve, thereby controlling the rotation speed of the drum 2 or the fixed shaft 6.

[0072] In another technical solution, a control device is also included. The control valve is an electrically controlled exhaust valve 3, and the control device is electrically connected to the electrically controlled speed control valve and the electrically controlled exhaust valve 3. By adding a control device, one-button control of the opening and closing of the electrically controlled exhaust valve 3 and the valve size of the electrically controlled speed control valve can be achieved, increasing the convenience of using the device.

[0073] A method for hoisting a ventilation and water pipe using the aforementioned tunnel ventilation and water pipe hoisting device includes the following steps:

[0074] 1) Move the device to the front of the working face, and connect the device to the high-pressure air duct through a drive air duct with a diameter of 15-25mm;

[0075] 2) Fix a steel wire rope on roller 2, and fix the other end of the steel wire rope to a water pipe with a diameter of 50-100mm.

[0076] 3) The first locking structure and the second locking structure are opened, and the third locking structure is closed. Compressed air is introduced through the connecting pipe, and the fixed shaft 6 drives the drum 2 to rotate together. The wire rope is wound on the drum 2, thereby pulling the air and water pipe to the front of the working face to meet the construction needs.

[0077] 4) After construction is completed, fix the air pipe on the roller 2, and introduce compressed air through the connecting pipe. The fixed shaft 6 drives the roller 2 to rotate together to wind the air pipe on the roller 2.

[0078] A method for providing power using the aforementioned tunnel ventilation pipe winch device involves closing the first locking structure and opening the second and third locking structures. Compressed air is introduced through a connecting pipe, keeping the drum 2 stationary, while the fixed shaft 6 can rotate relative to the drum 2. The fixed shaft 6 is connected to a power generation device so that the rotation of the fixed shaft 6 drives the power generation device to generate electricity.
