Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary equipment technology for highway construction, specifically to a drilling and grouting device. Background Technology
[0002] When widening and expanding roads, to reduce or delay longitudinal cracking of the pavement caused by uneven settlement between the old and new roadbeds, a common practice is to insert reinforcing bars into the interface between the old and new concrete surfaces. This involves embedding one end of the reinforcing bar into the old concrete slab using a rebar-planting method, and the other end into the newly constructed concrete pavement for overlap. Rebar installation is typically done manually using a hand-held electric drill. However, manually drilling with a hand-held electric drill requires the arm to bear the weight of the drill while simultaneously drilling towards the concrete slab, which easily leads to worker fatigue. Furthermore, the handheld drill has poor stability, making it difficult to meet requirements for hole location, drilling depth, and borehole straightness. Utility Model Content
[0003] The purpose of this invention is to provide a drilling and gluing device that facilitates vertical drilling and also has a gluing function.
[0004] To achieve the above objectives, this utility model provides a drilling and dispensing device, comprising a mobile frame, a drilling assembly, and a dispensing assembly. The mobile frame is equipped with casters with brakes at its bottom and can move longitudinally. The drilling assembly is located at the front end of the mobile frame in the direction of movement and includes a first drive assembly, a first movable plate, a second drive assembly, a second movable plate, and a drill. The first drive assembly drives the first movable plate to move laterally. The second drive assembly and the second movable plate are both located on the first movable plate, and the second drive assembly drives the second movable plate to move longitudinally. The drill is located on the second movable plate, and the drill bit of the drill extends laterally. The dispensing assembly is located at the rear end of the mobile frame in the direction of movement and includes a spray gun, a hose, a mixing pipe, two storage tanks, and two metering pumps. The hose includes a discharge end and two inlet ends. The two inlet ends are respectively connected to the two storage tanks, and the discharge end is connected to the spray gun through the mixing pipe. The two metering pumps are respectively connected to the two inlet ends.
[0005] As can be seen from the above solution, by setting casters with brakes, the mobile frame can be easily moved and stopped; by setting a second drive assembly and a second movable plate, the drill's longitudinal position can be finely adjusted via the second drive assembly after the mobile frame is in place, ensuring that the drill is aligned with the hole to be drilled; by setting a first drive assembly, the drill bit's lateral movement is controlled to control the drilling depth and ensure vertical drilling; by setting a glue-filling assembly, glue is applied to the drilled hole, facilitating subsequent rebar installation; and by setting a metering pump, resin and hardener are accurately mixed according to a preset ratio. The height of the drill in this invention matches the height of the hole to be drilled, eliminating the need for height adjustments during drilling, and offering the advantages of simple and convenient operation.
[0006] A further option is to mount the potting assembly longitudinally on the mobile frame.
[0007] A further option is to install a third movable plate and two longitudinal guide rails on the mobile frame, with the third movable plate slidably connected to the two longitudinal guide rails.
[0008] A further solution is to install a spiral channel inside the mixing tube.
[0009] As can be seen from the above scheme, the above setup is conducive to the uniform mixing of materials in the two storage tanks.
[0010] A further option is to fix the spiral channel in place, or to make the spiral channel rotatable.
[0011] A further embodiment is that the first drive assembly includes a first drive device, a first lead screw, a first lead screw nut, a first fixed seat, and two first guide rails. The two ends of the first lead screw are respectively connected to the first drive device and the first fixed seat. The first lead screw nut is movably connected between the two ends of the first lead screw. The two first guide rails are respectively disposed on both sides of the first lead screw. A first movable plate is connected to the first lead screw nut. Two first sliders are disposed at the bottom of the first movable plate. The first sliders are connected to the first guide rails.
[0012] As can be seen from the above scheme, the above settings facilitate accurate control of drilling depth.
[0013] A further solution is to have a limiting structure on the side of the mobile frame near the drill bit for contact with the surface to be drilled.
[0014] As can be seen from the above scheme, by using the above settings, the limiting structure can directly contact the surface to be drilled, which is beneficial to control the drilling depth.
[0015] A further option is that the limiting structure includes at least two limiting blocks arranged longitudinally. The first end of the limiting block is fixedly connected to the mobile frame, and the second end of the limiting block protrudes from the side wall of the mobile frame. The second end of the limiting block is provided with an abutment surface that extends longitudinally.
[0016] As can be seen from the above scheme, with the above settings, the contact surface abuts against the surface to be drilled during the movement of the mobile frame. On the one hand, this helps to ensure the distance between the drill and the surface to be drilled, making it easier to control the drilling depth. On the other hand, it allows the mobile frame to move in a direction parallel to the surface to be drilled, ensuring that the drill bit drills vertically.
[0017] A further option is that the limiting structure includes at least two fixed blocks and at least two rollers. The first end of the fixed block is fixedly connected to the mobile frame, the second end of the fixed block protrudes from the side wall of the mobile frame, and the rollers are rotatably connected to the second end of the fixed block. The two rollers are arranged longitudinally.
[0018] As can be seen from the above scheme, with the above settings, the contact surface abuts against the surface to be drilled during the movement of the mobile frame. On the one hand, this helps to ensure the distance between the drill and the surface to be drilled, making it easier to control the drilling depth. On the other hand, it allows the mobile frame to move in a direction parallel to the surface to be drilled, ensuring that the drill bit drills vertically. Moreover, by setting rollers, friction is reduced, making it easier for the mobile frame to move easily. Attached Figure Description

[0030] The first drive device 211 can accurately control the drilling depth of the drill rig 25, and the second drive device 231 can fine-tune the position of the drill rig 25 in the Y direction after the moving frame 1 is moved into place, so as to ensure that the drill rig 25 can be aligned with the position to be drilled.
[0031] The glue-filling assembly 3 can be fixed on the base plate 11, or the glue-filling assembly 3 can be movably mounted on the mobile frame 1 along the Y direction. In this embodiment, the latter is preferred. The mobile frame 1 is provided with a third movable plate 36 and two longitudinal guide rails 37. The longitudinal guide rails 37 extend along the Y direction. At least two third sliders are connected to the bottom wall of the third movable plate 36. The third sliders are slidably engaged with the longitudinal guide rails 37, that is, the third movable plate 36 is slidably connected to the two longitudinal guide rails 37.
[0032] The glue-dispensing assembly 3 can be moved by human power or by a third drive assembly, which includes a motor and a lead screw kinematic pair. In this embodiment, the former is preferred.
[0033] The dispensing assembly 3 includes a spray gun 31, a hose 32, a mixing tube 33, two storage tanks 34, and two metering pumps 35.

[0036] Second embodiment of the drilling and dispensing device:
[0037] See Figure 3 Based on the first embodiment of the drilling and gluing device described above, this embodiment provides a drilling and gluing device including a limiting structure. The limiting structure is disposed on the side of the mobile frame 1 near the drill bit 251 and is used to directly contact the surface to be drilled.
[0038] In one embodiment, the limiting structure includes at least two limiting blocks 5 arranged along the Y direction.

The rollers are rotatably connected to the second end of the fixing blocks, and the two rollers are arranged along the Y direction. The peripheral wall of the rollers can roll into contact with the side wall of the road, ensuring that the mobile frame 1 moves along the Y direction while reducing friction. The arrangement of the rollers ensures that the mobile frame 1 can be as close as possible to the surface to be drilled during movement. This ensures that the drill bit 251 can start drilling from the same starting point each time, and also ensures that the base plate 11 is parallel to the Y direction, thereby ensuring that the drill bit 251 can drill perpendicularly.
[0040] In summary, this invention features several advantages: First, by incorporating casters 12 with brakes, the mobile frame 1 can be easily moved and stopped. Second, by including a second drive assembly 23 and a second movable plate 24, the vertical position of the drill 25 can be finely adjusted via the second drive assembly 23 after the mobile frame 1 is in place, ensuring alignment between the drill 25 and the hole to be drilled. Third, by including a first drive assembly 21, the drill bit 251 is controlled to move laterally, thereby controlling the drilling depth and ensuring vertical drilling. Fourth, by including a glue-filling assembly 3, glue is applied to the drilled hole, facilitating subsequent rebar installation. Fifth, by including a metering pump 35, resin and hardener are accurately mixed according to a preset ratio. The height of the drill 25 matches the height of the hole to be drilled, eliminating the need for height adjustments during drilling and offering advantages of simple and convenient operation.
