Description

Technical Field

[0001] This utility model relates to the field of cement pavement construction technology, specifically to a cement pavement inclined drilling machine. Background Technology

[0002] A considerable portion of my country's existing cement concrete pavements are nearing or exceeding their design lifespan. Some, though not yet at their design lifespan, are experiencing various defects due to factors such as increased traffic volume, heavier vehicle axle loads, or design and construction issues. These defects include aging, slab breakage, localized settlement, joint damage, and insufficient strength from backfill repairs after excavation. Consequently, the old concrete pavements offer poor driving comfort. To improve road service levels, the first step in renovation should be the reinforcement of cement pavements.

[0003] Among them, joints mainly refer to the connection between the new road surface and the old road surface during the overlay and reconstruction of cement road surface and the paving of cement road surface in sections. In order to reinforce the connection between the new road surface and the old road surface, a long trench is usually dug along the connection between the new road surface and the old road surface, steel bars are laid in the long trench and then filled with concrete to connect the new road surface and the old road surface. However, this construction method requires excavation and backfilling of cement road surface, which has low construction efficiency. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the main technical problem solved by this utility model is that the existing construction method for reinforcing the joints of cement pavement requires excavation and backfilling of the cement pavement, which results in low construction efficiency.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a cement pavement inclined drilling machine, comprising:

[0006] frame;

[0007] A drilling frame is mounted on a machine frame, and the angle of the drilling frame is adjustable;

[0008] The drilling machine is slidably mounted on the drilling frame along the length of the drill bit; and

[0009] An advance member that can push the drilling machine to move along the length of the drill bit.

[0010] In this invention, the angle of the drill bit on the drilling machine is adjusted by the drilling frame, so that the drill bit is tilted and facing the joint of the cement pavement. Then, the drilling machine drives the drill bit to rotate, and the drilling machine is moved by the propulsion component, so that the drill bit tilts and drills into the new pavement and the old pavement, drilling multiple holes along the joint of the cement pavement, inserting steel bars into the holes, and then pouring concrete to connect the new pavement and the old pavement at the joint, thus reinforcing the joint of the cement pavement. Moreover, by using drilling instead of excavation and backfilling, the construction efficiency can be greatly improved.

[0011] Preferably, the angle of the drilling frame is adjustable via a lifting mechanism, which includes a lifting member and a connecting member. One end of the lifting member is hinged to the frame, and the other end is hinged to the tail end of the drilling frame. One end of the connecting member is hinged to the front end of the drilling frame, and the other end is mounted on the frame. The angle of the drilling frame is adjusted by controlling the extension and retraction of the lifting member to control the rotation of the drilling frame on the connecting member.

[0012] Preferably, the end of the connector away from the drilling frame is mounted on the frame via an adjusting assembly; the adjusting assembly includes a lead screw, a nut seat, and a motor; the lead screw is rotatably mounted on the frame; the nut seat is connected to the lead screw via a ball screw and nut pair; the end of the connector away from the drilling frame is hinged to the nut seat; the motor can drive the lead screw to rotate. The motor drives the lead screw to rotate, causing the lead screw to slide the nut seat, which in turn drives the connector to rotate via a universal joint. This allows adjustment of the height of the connector near the drilling frame, thereby secondary adjustment of the drilling frame angle and increasing the angle adjustment range of the drilling frame.

[0013] Preferably, the connecting component includes a threaded rod, a threaded sleeve, and a universal joint; one end of the threaded rod is hinged to the drilling frame, and the other end of the threaded rod extends into the threaded sleeve and is threadedly connected to the threaded sleeve; one section of the universal joint is coaxially fixed to the threaded sleeve, and the other section of the universal joint is fixedly connected to a nut seat; the motor can drive the universal joint to rotate through the connecting assembly. The motor drives the universal joint to rotate, which in turn drives the threaded sleeve to rotate, thereby moving the threaded rod, thus further adjusting the height of the connecting component near the drilling frame end, thereby further increasing the angle adjustment range of the drilling frame.

[0014] Preferably, the connecting assembly includes a first sprocket, a second sprocket, a tensioning wheel, a tensioning plate, a torsion spring, a chain, a first bevel gear, and a second bevel gear. The first bevel gear and the first sprocket are rotatably mounted on the frame and are coaxially fixed. The second bevel gear is coaxially fixed to the lead screw and meshes with the first bevel gear. The second sprocket is coaxially fixed to a section of the universal joint near the nut seat, and is connected to the first sprocket via the chain. The tensioning wheel is rotatably mounted on one end of the tensioning plate, and the other end of the tensioning plate is hinged to the frame. The torsion spring is installed at the hinge point of the tensioning plate to push the tensioning wheel against the chain to tension the chain. The motor drives the second bevel gear to rotate via the lead screw, which in turn drives the first bevel gear meshing with it to rotate. The first bevel gear drives the first sprocket, which is coaxially fixed with it, to rotate. The first sprocket drives the second sprocket to rotate via the chain, and the second sprocket drives the universal joint to rotate; thereby moving the threaded rod.

[0015] Preferably, a lower crossbeam is installed below the drill bit end of the drilling frame. The lower crossbeam supports the lower part of the drilling frame near the drill bit end.

[0016] Preferably, the system further includes a guide rod, which is fixedly mounted on the drilling frame along the length of the drill bit, and the drilling machine is slidably connected to the guide rod. The guide rod guides the sliding of the drilling machine, thereby improving the stability of the drilling machine during drilling.

[0017] Preferably, multiple drilling machines are provided. By installing multiple drilling machines on the drilling frame, multiple drilling machines can be driven by the propeller to drill simultaneously, thereby improving drilling efficiency.

[0018] Preferably, a traveling mechanism is installed on the frame. The position of the frame is controlled by the traveling mechanism, thereby allowing for convenient adjustment of the drilling position of the drilling machine on the cement pavement.

[0019] Preferably, the walking mechanism is a track. The track controls the position of the frame, thereby increasing the contact area with the concrete road surface and thus increasing the friction between the machine and the ground.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] 1. Replacing excavation and backfilling with drilling significantly improves construction efficiency. In this invention, the angle of the drill bit on the drilling machine is adjusted by the drilling frame, causing the drill bit to be tilted and facing the joint of the cement pavement. The drilling machine then drives the drill bit to rotate, and the feed mechanism moves the drilling machine, causing the drill bit to tilt and drill into the new and old pavement, creating multiple holes along the cement pavement joint. Reinforcing bars are inserted into these holes, and then concrete is poured in, thus connecting the new and old pavement at the joint and reinforcing the cement pavement joint. Furthermore, replacing excavation and backfilling with drilling greatly improves construction efficiency.

[0022] 2. It increases the angle adjustment range of the drilling frame. The motor drives the lead screw to rotate, causing the lead screw to slide the nut seat. The nut seat drives the connecting part to rotate through the universal joint, thereby adjusting the height of the connecting part near the drilling frame. This allows for secondary adjustment of the drilling frame's angle, increasing the angle adjustment range. Simultaneously, the motor drives the universal joint to rotate, which in turn drives the threaded sleeve to rotate, thereby moving the threaded rod. This further adjusts the height of the connecting part near the drilling frame, further increasing the angle adjustment range of the drilling frame. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] See Figures 1-4 The present invention provides an embodiment of a cement pavement inclined drilling machine, comprising: a frame 1, a drilling frame 2, a drilling machine 3, and a propulsion component 4; the drilling frame 2 is mounted on the frame 1, and the angle of the drilling frame 2 is adjustable; the drilling machine 3 is slidably mounted on the drilling frame 2 along the length direction of the drill bit; furthermore, multiple drilling machines 3 are provided; by mounting multiple drilling machines 3 on the drilling frame 2, the propulsion component 4 can push multiple drilling machines 3 to drill simultaneously, thereby improving drilling efficiency. The propulsion component 4 can push the drilling machine 3 to move along the length direction of the drill bit. In specific implementations, the propulsion component 4 can be a cylinder, a hydraulic cylinder, an electric push rod, etc.

[0033] In practice, the frame 1 is moved to the location of the cement pavement joint to be reinforced, and the angle of the drill bit on the drilling machine 3 is adjusted by the drilling frame 2 so that the drill bit is tilted and facing the cement pavement joint. Then, the drilling machine 3 drives the drill bit to rotate, and the drilling machine 3 is moved by the propeller 4, so that the drill bit tilts and drills into the new pavement and the old pavement, drilling multiple holes along the cement pavement joint, inserting steel bars into the holes, and then pouring concrete to connect the new pavement and the old pavement at the joint, thus reinforcing the cement pavement joint. Moreover, by using drilling instead of excavation and backfilling, the construction efficiency can be greatly improved.

[0034] See Figures 1-4 In other embodiments, the angle of the drilling frame 2 is adjustable via a lifting mechanism 5, which includes a lifting member 51 and a connecting member 52. One end of the lifting member 51 is hinged to the frame 1, and the other end of the lifting member 51 is hinged to the tail end of the drilling frame 2. One end of the connecting member 52 is hinged to the front end of the drilling frame 2, and the other end of the connecting member 52 is mounted on the frame 1. The drilling frame 2 is rotated on the connecting member 52 by controlling the extension and retraction of the lifting member 51, thereby adjusting the angle of the drilling frame 2. In specific implementations, the lifting member 51 can be a cylinder, a hydraulic cylinder, an electric push rod, etc. Furthermore, a lower crossbeam 6 is installed below the end of the drilling frame 2 near the drill bit. The lower crossbeam 6 can support the lower part of the drilling frame 2 near the drill bit.

[0035] See Figures 1-4 In other embodiments, the end of the connector 52 away from the drilling frame 2 is mounted on the frame 1 via an adjusting assembly 53. The adjusting assembly 53 includes a lead screw 531, a nut seat 532, and a motor 533. The lead screw 531 is rotatably mounted on the frame 1. The nut seat 532 is connected to the lead screw 531 via a ball screw nut pair. The end of the connector 52 away from the drilling frame 2 is hinged to the nut seat 532. The motor 533 can drive the lead screw 531 to rotate. In specific implementation, when the motor 533 is activated, it drives the lead screw 531 to rotate, causing the lead screw 531 to slide the nut seat 532. The nut seat 532 drives the connector 52 to rotate via a universal joint 523, thereby adjusting the height of the connector 52 near the drilling frame 2, thus adjusting the angle of the drilling frame 2 a second time and increasing the angle adjustment range of the drilling frame 2.

[0036] See Figures 1-4In other embodiments, the connector 52 includes a threaded rod 521, a threaded sleeve 522, and a universal joint 523. One end of the threaded rod 521 is hinged to the drill holder 2, and the other end of the threaded rod 521 extends into the threaded sleeve 522 and is threadedly connected to the threaded sleeve 522. One section of the universal joint 523 is coaxially fixed to the threaded sleeve 522, and the other section of the universal joint 523 is fixedly connected to the nut seat 532. The motor 533 can drive the universal joint 523 to rotate through the connecting assembly 54. In specific implementation, the motor 533 drives the universal joint 523 to rotate, which in turn drives the threaded sleeve 522 to rotate, thereby moving the threaded rod 521. This further adjusts the height of the connector 52 near the drill holder 2, thereby further increasing the angle adjustment range of the drill holder 2.

[0037] See Figures 1-4 In other embodiments, the connecting assembly 54 includes a first sprocket 541, a second sprocket 542, a tensioning wheel 543, a tensioning plate 544, a torsion spring, a chain 545, a first bevel gear, and a second bevel gear. The first bevel gear and the first sprocket 541 are rotatably mounted on the frame 1 and are coaxially fixed. The second bevel gear is coaxially fixed with the lead screw 531 and meshes with the first bevel gear. The second sprocket 542 is coaxially fixed on a section of the universal joint 523 near the nut seat 532, and is connected to the first sprocket 541 via the chain 545. The tensioning wheel 543 is rotatably mounted on one end of the tensioning plate 544, and the other end of the tensioning plate 544 is hinged to the frame 1. The torsion spring is mounted at the hinge point of the tensioning plate 544 to push the tensioning wheel 543 against the chain 545 to tension the chain 545.

[0038] In practice, the motor 533 operates, driving the second bevel gear to rotate via the lead screw 531. The second bevel gear drives the first bevel gear meshing with it to rotate, which in turn drives the first sprocket 541, which is coaxially fixed with it, to rotate. The first sprocket 541 drives the second sprocket 542 to rotate via the chain 545, which in turn drives the universal joint 523 to rotate. This causes the threaded rod 521 to move. Furthermore, the tensioning plate 544 rotates due to the elasticity of the torsion spring, ensuring that the tensioning wheel 543 on the tensioning plate 544 is always in contact with the chain 545, thus tensioning the chain 545 and ensuring that the chain 545 has sufficient length when the second sprocket 542 moves.

[0039] See Figures 1-4 In other embodiments, a guide rod 7 is also included. The guide rod 7 is fixedly installed on the drilling frame 2 along the length of the drill bit, and the drilling machine 3 is slidably connected to the guide rod 7. The guide rod 7 guides the sliding of the drilling machine 3, thereby improving the stability of the drilling machine 3 during drilling; specifically, guide rods 7 are respectively provided on both sides of the pusher 4.

[0040] See Figures 1-4 In another embodiment, a traveling mechanism is installed on the frame 1; the position of the frame 1 is controlled by the traveling mechanism, thereby facilitating the adjustment of the drilling position of the drilling machine 3 in the cement pavement. Further, the traveling mechanism is a track 8; the position of the frame 1 is controlled by the track 8, thereby increasing the contact area with the cement pavement and increasing the friction between the frame and the ground. Specifically, the traveling mechanism can also be a swivel caster, wheel, or other structure capable of moving the frame 1.
