Description

Technical Field

[0001] This invention relates to the field of drilling technology, and in particular to a mobile rotary drilling device for road and bridge construction. Background Technology

[0002] Roads and bridges generally consist of several major parts, including roadbed, pavement, bridge, tunnel engineering, and traffic engineering facilities. During construction, drilling equipment is usually used to make holes for the installation of construction materials. However, when constructing on a bridge, the ground has a certain curvature. In this case, the drilling rig cannot keep perpendicular to the ground when drilling, resulting in the hole not being perpendicular to the ground.

[0003] Therefore, a mobile rotary drilling device for road and bridge construction is proposed to solve the above problems. Summary of the Invention

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a mobile rotary drilling device for road and bridge construction, comprising a support plate, a drilling rig being disposed on one side of the support plate, and a drill bit being fixedly installed at the output end of the drilling rig; an adjustment and buffer mechanism for adjusting the angle of the drilling rig and for buffering when the drill bit is working; wherein, the adjustment and buffer mechanism includes an adjustment component fixedly installed on one side of the drilling rig, and a buffer component being disposed between the drill bit and the drilling rig.

[0005] Preferably, there are two support plates, which are distributed on both sides of the drilling rig. Each of the two support plates has a lifting plate on an adjacent side. Each of the two lifting plates has multiple movable slots on one side of the support plate. Each of the two support plates has multiple fixed plates fixedly connected to an adjacent side of the support plate. Each of the multiple fixed plates is located inside the corresponding movable slot. A positioning plate is fixedly connected inside the movable slot. A first screw is rotatably connected to one side of the positioning plate. The first screw is threadedly connected to the positioning plate. Multiple casters are fixedly installed at the bottom of each of the two support plates.

[0006] Preferably, a motor is fixedly installed on the surface of each of the two support plates, and a second screw is fixedly connected to the output end of each motor. The surfaces of the two second screws are threadedly connected to the same movable plate, and the drilling rig is located on one side of the movable plate.

[0007] Preferably, the adjustment assembly includes an opening on the surface of the movable plate, a turntable rotatably connected to one side of the opening, the drilling rig connected to one side of the turntable, two support plates fixedly connected inside the opening, the two support plates distributed on both sides of the turntable, support rods installed through the surface of each support plate, and arc-shaped plates fixedly installed on adjacent sides of each of the two support rods, both of the arc-shaped plates contacting the turntable, and a first spring sleeved on the outer side of each support rod, the two ends of the first spring being connected to the arc-shaped plate and the support plate respectively.

[0008] Preferably, the surface of the turntable is provided with multiple evenly distributed slots, and the two arc plates are integrally connected with multiple evenly distributed protrusions on the side that contacts the turntable. The multiple protrusions are locked with the corresponding slots, and the output end of the drilling rig is fixedly installed with a auger rod.

[0009] Preferably, the buffer assembly includes a sealing tube fixedly installed at one end of the auger rod, a piston rod fixedly connected to one side of the drill bit, the piston rod being slidably connected to the sealing tube, and a buffer ring sleeved on the outer side of the piston rod, with the upper and lower sides of the buffer ring contacting the sealing tube and the drill bit respectively.

[0010] Preferably, a second spring is fixedly connected to one end of the piston rod located inside the sealing tube, the other end of the second spring is connected to the sealing tube, a protective shell is slidably connected to the surface of the sealing tube, and the other side of the protective shell is connected to the drill bit.

[0011] Preferably, the bottom ends of both lifting plates are connected to top plates, and both top plates are triangular in shape.

[0012] The beneficial effects of this invention are:

[0013] 1. By setting the adjustment component, when encountering curved ground, if the drill is not perpendicular to the ground, the two curved plates can be pushed away from each other, and the two first springs will deform. By rotating the turntable, the angle between the drill and the ground can be adjusted so that the drill can always be perpendicular to the ground, ensuring the accuracy of drilling.

[0014] 2. By setting up a buffer component, if the drill bit vibrates during drilling, it can push the piston rod to slide in the sealed tube, compressing the gas inside the sealed tube. The compression of the internal gas buffers the piston rod. Furthermore, when the drill bit vibrates, it continuously compresses the buffer ring, which can reduce the force of the drill bit colliding with the piston rod. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In specific implementation: As shown in Figures 1-4, a mobile rotary drilling device for road and bridge construction includes a support plate 1, a drilling rig 208 is installed on one side of the support plate 1, and a drill bit 301 is fixedly installed at the output end of the drilling rig 208; an adjustment buffer mechanism is used to adjust the angle of the drilling rig 208 and to buffer the drill bit 301 when it is working; wherein, the adjustment buffer mechanism includes an adjustment component 2 fixedly installed on one side of the drilling rig 208, and a buffer component 3 is provided between the drill bit 301 and the drilling rig 208. The drilling angle of the drilling rig 208 can be adjusted by adjusting the adjustment component 2, which can ensure that the drilling rig 208 is perpendicular to the ground when drilling. When the drilling rig 208 is working, it drives the drill bit 301 to drill. At this time, the buffer component 3 can provide buffer for the drill bit 301 to prevent the connection of the drill bit 301 from breaking during drilling. There are two support plates 1, which are distributed on both sides of the drilling rig 208. Each of the two support plates 102 is equipped with a lifting plate 102 on an adjacent side. Multiple movable slots 104 are formed on the side of each lifting plate 1 closest to the support plate 1. Multiple fixed plates 105 are fixedly connected to adjacent sides of each support plate 1. The fixed plates 105 are located inside the corresponding movable slots 104. A positioning plate 106 is fixedly connected inside the movable slot 104. A first screw 107 is rotatably connected to one side of the positioning plate 106, and the first screw 107 is threadedly connected to the positioning plate 106. Multiple casters 101 are fixedly installed at the bottom of each support plate 1. The casters 101 facilitate the movement of the support plate 1 and the drilling rig 208. When drilling is required, the multiple first screws 107 can be rotated. The first screws 107 threadedly move with the fixed plates 105, causing the first screws 107 to move the positioning plates 106 downwards. This allows the positioning plates 106 to move the lifting plates 102 downwards, thus lifting the support plate 102. Once supported, the drill 208 can be fixed in place, facilitating drilling. Motors 108 are fixedly mounted on the surfaces of both support plates 1, and second screws 109 are fixedly connected to the output ends of each motor 108. The surfaces of the two second screws 109 are threadedly connected to the same movable plate 103. The drill 208 is located on one side of the movable plate 103. During drilling, the two motors 108 can be activated to drive the second screws 109, causing the second screws 109 to move threadedly with the movable plate 103, thus moving the movable plate 103 and controlling the height of the drill 208.

[0022] As shown in Figures 1 and 3, the adjusting assembly 2 includes an opening 204 on the surface of the movable plate 103. A turntable 201 is rotatably connected to one side of the opening 204. The drilling rig 208 is connected to one side of the turntable 201. Two support plates 205 are fixedly connected inside the opening 204. The two support plates 205 are distributed on both sides of the turntable 201. Support rods 206 are installed through the surface of each support plate 205. An arc-shaped plate 203 is fixedly installed on the adjacent side of each of the two support rods 206. Both arc-shaped plates 203 are in contact with the turntable 201. A first spring 207 is sleeved on the outside of the support rods 206. The two ends of the first spring 207 are connected to the arc-shaped plate 203 and the support plate 205, respectively. When encountering an arc-shaped surface, the drilling rig 208 is not perpendicular to the ground, and the adjusting assembly 2 can push the two arc-shaped plates 203. The two springs 207 deform as they move away from each other, adjusting the angle between the drill 208 and the ground by rotating the turntable 201. This ensures that the drill 208 remains perpendicular to the ground, guaranteeing drilling accuracy. The surface of the turntable 201 has multiple evenly distributed slots 202. The sides of the two arc-shaped plates 203 that contact the turntable 201 are integrally connected with multiple evenly distributed protrusions, which are locked into the corresponding slots 202. The output end of the drill 208 is fixedly equipped with a auger rod 209. When the arc-shaped plates 203 contact the turntable 201, the multiple protrusions on their surfaces lock into the corresponding slots 202, allowing the two arc-shaped plates 203 to better secure the turntable 201 when in contact with it.

[0023] As shown in Figures 1, 3, and 4, the buffer assembly 3 includes a sealing tube 304 fixedly installed at one end of the auger rod 209. A piston rod 302 is fixedly connected to one side of the drill bit 301, and the piston rod 302 is slidably connected to the sealing tube 304. A buffer ring 303 is sleeved on the outer side of the piston rod 302. The upper and lower sides of the buffer ring 303 are in contact with the sealing tube 304 and the drill bit 301, respectively. During drilling, if the drill bit 301 vibrates, it can push the piston rod 302 to slide and seal within the sealing tube 304, compressing the gas inside the sealing tube 304. The compression of the internal gas buffers the piston rod 302. Furthermore, when the drill bit 301 vibrates, it continuously compresses the buffer ring 303, which reduces the force of the drill bit 301 colliding with the piston rod 302. A second spring 305 is fixedly connected to one end of the piston rod 302 located inside the sealing tube 304. The other end is connected to the sealing tube 304. A protective shell 306 is slidably connected to the surface of the sealing tube 304. The other side of the protective shell 306 is connected to the drill bit 301. When the piston rod 302 moves into the sealing tube 304, it will also squeeze the second spring 305. After the hole is drilled, the drill bit 301 can be reset by the second spring 305. After the hole is drilled, when the drill bit 301 is moved out of the hole, the protective shell 306 can protect the connection between the drill bit 301 and the sealing tube 304. The bottom ends of the two lifting plates 102 are connected to the top plates. Both top plates are set in a triangular shape. The top plates can provide support when in contact with the ground, and can easily enter the ground when encountering soft ground, making the support more stable.

[0024] In use, when drilling is required, multiple first screws 107 can be rotated. The first screws 107 and the fixed plate 105 move threadedly, causing the first screws 107 to drive the positioning plate 106 downwards. The positioning plate 106 then drives the lifting plate 102 downwards, allowing the lifting plate 102 to support the support plate 1, thus fixing it in place and facilitating drilling with the drill 208. Two motors 108 can be activated to drive the second screw 109, causing the second screw 109 and the movable plate 103 to move threadedly, thus controlling the height of the drill 208. When encountering curved ground, the drill 208 is not perpendicular to the ground. In this case, the two curved plates 203 can be pushed away from each other, and the two first springs 207 deform. By rotating the turntable 201, the angle between the drill 208 and the ground can be adjusted, allowing the drill 208 to move more smoothly. It can always be perpendicular to the ground to ensure drilling accuracy. When the curved plate 203 comes into contact with the turntable 201, the multiple protrusions on its surface are locked together with the corresponding slots 202, which allows the two curved plates 203 to better fix the turntable 201 when they come into contact with it. When drilling, if the drill bit 301 vibrates, it can push the piston rod 302 to slide in the sealing tube 304, squeezing the gas in the sealing tube 304. The internal gas compression buffers the piston rod 302. When the drill bit 301 vibrates, it continuously squeezes the buffer ring 303, which can reduce the force of the drill bit 301 colliding with the piston rod 302.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
