Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to an angle-adjustable multi-head water-grinding drill. Background Technology

[0002] Tunnel construction refers to the process of building tunnels underground, underwater, or within mountains for the purpose of laying railways or constructing highways for motor vehicles. Tunnel construction requires the scientific selection of excavation, support, and lining methods and techniques, taking into account topography, geomorphology, and hydrogeological conditions, and the development of detailed safety technical measures.

[0003] During tunnel construction, tunnel excavation is required, which typically involves loosening, breaking, excavating, and transporting the excavated soil or rock. During the excavation process, water-cooled drilling rigs are used to drill holes around the tunnel, thereby facilitating lateral excavation of the tunnel through the connection between multiple holes.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. Most water-cooled drilling rigs used in common tunnel construction are fixed on the drill bit bracket in an integrated manner. However, in actual operation, drilling operations with a certain arc are required, but common water-cooled drilling rigs are often not easy to adjust the angle, which reduces the adaptability of the water-cooled drilling rig and thus affects the efficiency of tunnel construction; 2. When using a water-cooled drilling rig for drilling operations, the bracket of the water-cooled drilling rig is often not easy to fix after being moved to the construction position, which affects the drilling accuracy of the water-cooled drilling rig and thus affects the effect of tunnel construction. Utility Model Content

[0005] The purpose of this utility model is to provide an angle-adjustable multi-head water-jet drilling rig to solve the problems mentioned in the background art, where the support structure of most water-jet drilling rigs is an integrated fixed structure, which makes it inconvenient to adjust the angle of the water-jet drilling rig according to the requirements of curved drilling, resulting in reduced adaptability of the water-jet drilling rig and thus affecting the efficiency of tunnel construction. Furthermore, after the water-jet drilling rig is moved to a suitable construction position, it is often difficult to fix it, which affects the drilling accuracy and thus the effect of tunnel construction. To achieve the above objectives, this utility model provides the following technical solution: an angle-adjustable multi-head water-jet drilling rig, including a moving mechanism, a construction mechanism mounted on the top of the moving mechanism, and an auxiliary mechanism mounted on one end of the bottom of the construction mechanism.

[0006] The moving mechanism includes a movable base, with casters installed at the four corners of the bottom of the movable base. Locking rods are installed inside the casters. A hydraulic lifting assembly is installed at the top center of the movable base. Adjustable seats are welded to both sides of the movable base. Limiting grooves extend through the exterior of each adjustable seat. An adjusting motor is installed on the top of the adjusting seat. A threaded shaft is driven and connected to the bottom of the adjusting motor. A limiting ring is threaded onto the exterior of the threaded shaft. One end of a limiting rod is rotatably connected to the exterior of the limiting ring, and a support rod is rotatably connected to the other end of the limiting rod.

[0007] The construction mechanism includes a lifting support, with docking seats installed at both the upper and lower ends of the lifting support, and traction motors installed at both the upper and lower ends of the lifting support. One end of the traction motor is linearly connected to a traction seat. A rotating support is rotatably connected to the center of the lifting support. Hydraulic telescopic components are installed on both sides of the rotating support. Scissor bar grooves are installed on both sides of the rotating support. Scissor bar components are slidably connected inside the scissor bar grooves. A construction support is installed at the other end of the hydraulic telescopic component. A water-grinding drill body is installed at one end of the construction support.

[0008] The auxiliary mechanism includes a fixed base, with one end of a fixed rod rotatably connected inside the fixed base. Fixed grooves extend through both sides of the fixed rod, and fixed screws extend through the fixed grooves. Fixed nuts are threaded to both ends of the fixed screws. A telescopic rod is sleeved on the other end of the fixed rod. A fixed hole extends through one end of the telescopic rod, and a connecting base is rotatably connected to the other end of the telescopic rod.

[0009] More preferably, the threaded shaft is connected to the bottom of the adjusting motor via a drive connection to form a rotatable connection structure with one end of the limiting groove, and the limiting ring is connected to the outside of the threaded shaft via a threaded connection to form a sliding connection structure with the inner wall of the limiting groove, and the limiting rod is connected to the outside of the limiting ring via a rotatable connection to form a sliding connection structure with the outer wall of the limiting groove.

[0010] More preferably, the limiting ring is rotatably connected to three limiting rods, and the bottom of the support rod and the bottom of the adjusting seat form a rotatable connection structure, and one end of the support rod is rotatably connected to the limiting rod and fits against the ground.

[0011] More preferably, the lifting support has a C-shaped structure, and traction motors are installed on the inner walls of both the upper and lower ends of the lifting support, with traction seats installed on one side of each of the two construction supports.

[0012] More preferably, two scissor bar assemblies are respectively provided on both sides of the hydraulic telescopic assembly, and the other end of the scissor bar assembly is installed on one side of the construction support, and the maximum telescopic distance of the scissor bar assembly is the same as the maximum telescopic distance of the hydraulic telescopic assembly.

[0013] More preferably, when the connecting seat is installed at one end of the bottom of the lifting bracket, and the telescopic rod is at its maximum telescopic distance within the fixed rod, the vertical height of the fixed seat and the connecting seat is the same as the maximum lifting distance of the hydraulic lifting assembly.

[0014] In a further preferred embodiment, the fixing screw forms a through-connection structure by passing through the fixing groove and the fixing hole, and the fixing nut forms a fitting connection structure by threading the two ends of the fixing screw and the two sides of the fixing rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, a telescopic and rotatable construction support is installed inside the water-grinding drill, which facilitates adjustment of the corresponding position according to the requirements of the arc-shaped drilling. The rotation angle is controlled by the traction rope and hydraulic telescopic component, which improves the drilling effect of the water-grinding drill. Compared with the conventional integrated water-grinding drill, it has better adaptability, facilitates tunnel construction operations, and improves the efficiency of tunnel construction.

[0017] In this invention, a lockable universal wheel is installed at the bottom of the support of the water-grinding drill rig, which works in conjunction with the limiting support component for auxiliary fixation.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: an angle-adjustable multi-head water-grinding drill, including a moving mechanism 1, a construction mechanism 2 installed on the top of the moving mechanism 1, and an auxiliary mechanism 3 installed at one bottom end of the construction mechanism 2.

[0025] The moving mechanism 1 includes a moving base 101. Universal wheels 102 are installed at the four corners of the bottom of the moving base 101. Locking rods 103 are installed inside the universal wheels 102. A hydraulic lifting assembly 104 is installed at the top center of the moving base 101. Adjusting seats 105 are welded to both sides of the moving base 101. Limiting grooves 106 extend through the outside of the adjusting seats 105. An adjusting motor 107 is installed on the top of the adjusting seats 105. A threaded shaft 108 is driven and connected to the bottom of the adjusting motor 107. A limiting ring 109 is threadedly connected to the outside of the threaded shaft 108. One end of a limiting rod 1010 is rotatably connected to the outside of the limiting ring 109. A support rod 1011 is rotatably connected to the other end of the limiting rod 1010.

[0026] Construction mechanism 2 includes a lifting support 201. The upper and lower ends of the lifting support 201 are equipped with docking seats 202. The upper and lower ends of the lifting support 201 are equipped with traction motors 203. One end of the traction motor 203 is linearly connected to a traction seat 204. The center of the lifting support 201 is rotatably connected to a rotating support 205. The two sides of the rotating support 205 are equipped with hydraulic telescopic components 206. The two sides of the rotating support 205 are equipped with scissor bar grooves 207. The inside of the scissor bar grooves 207 is slidably connected to a scissor bar assembly 208. The other end of the hydraulic telescopic component 206 is equipped with a construction support 209. One end of the construction support 209 is equipped with a water-grinding drill body 2010.

[0027] The auxiliary mechanism 3 includes a fixed base 301, one end of a fixed rod 302 is rotatably connected inside the fixed base 301, fixed grooves 303 pass through both sides of the fixed rod 302, fixed screws 304 pass through the inside of the fixed grooves 303, fixed nuts 305 are threaded to both ends of the fixed screws 304, a telescopic rod 306 is sleeved on the other end of the fixed rod 302, a fixed hole 307 passes through one end of the telescopic rod 306, and a connecting seat 308 is rotatably connected to the other end of the telescopic rod 306.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the threaded shaft 108 is connected to the bottom of the adjusting motor 107 via a drive connection to form a rotatable connection structure with one end of the limiting groove 106. The limiting ring 109 is connected to the outside of the threaded shaft 108 via a threaded connection to form a sliding connection structure with the inner wall of the limiting groove 106. The limiting rod 1010 is connected to the outside of the limiting ring 109 via a rotatable connection to form a sliding connection structure with the outer wall of the limiting groove 106. By setting the adjusting motor 107 on both sides of the movable base 101 to adjust the height of the limiting ring 109 in the limiting groove 106, it is convenient to adjust the support height required by the water mill drilling machine, so as to meet the support requirements of different ground heights and improve the support effect of the water mill drilling machine.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, the limiting ring 109 is externally rotatably connected to three limiting rods 1010, and the bottom of the support rod 1011 and the bottom of the adjusting seat 105 form a rotatable connection structure. One end of the support rod 1011 is rotatably connected to the limiting rod 1010 and is in contact with the ground. The three support rods 1011 on both sides jointly support and fix the mobile base 101, improving the contact effect with the ground. The lockable caster 102 further fixes the mobile base 101, improving the stability of the water-grinding drill and facilitating drilling operations.

[0030] In this embodiment, as Figure 1 and Figure 3As shown, the lifting support 201 has a C-shaped structure, and traction motors 203 are installed on the inner walls of both the upper and lower ends of the lifting support 201. The traction seats 204 are respectively installed on one side of the two construction supports 209. By setting the C-shaped lifting support 201 in conjunction with the rotatable rotating support 205, the water-grinding drill is driven to rotate under the action of the traction rope, thereby realizing the adjustment of the drilling angle, which is convenient for arc drilling and improves the adaptability of the water-grinding drill.

[0031] In this embodiment, as Figure 1 and Figure 3 As shown, two scissor arms assemblies 208 are respectively provided on both sides of the hydraulic telescopic assembly 206, and the other end of the scissor arm assembly 208 is installed on one side of the construction support 209. The maximum telescopic distance of the scissor arm assembly 208 is the same as the maximum telescopic distance of the hydraulic telescopic assembly 206. By setting the hydraulic telescopic assembly 206 inside, the water-jet drilling machine can be adjusted in lateral distance. With the traction rotation of the traction motor 203, it is convenient to perform arc drilling operations with different curvatures. At the same time, the scissor arm assemblies 208 on both sides of the hydraulic telescopic assembly 206 further limit the lateral movement position of the construction support 209, so as to avoid deviation during hydraulic operation and affect the drilling accuracy of the water-jet drilling machine. This further improves the adaptability of the water-jet drilling machine for arc drilling and improves the effect of tunnel construction.

[0032] In this embodiment, as Figure 1 and Figure 4 As shown, the connecting seat 308 is installed at one bottom end of the lifting bracket 201, and when the telescopic rod 306 is at its maximum telescopic distance within the fixed rod 302, the vertical height of the fixed seat 301 and the connecting seat 308 is the same as the maximum lifting distance of the hydraulic lifting assembly 104. By setting an auxiliary mechanism 3 at one bottom end of the lifting bracket 201 in conjunction with the internal telescopic rod 306 to provide auxiliary support for the lifting bracket 201, the stability of the water mill drilling machine during operation within the lifting bracket 201 is improved, deviation during construction is avoided, and the accuracy of the water mill drilling machine construction is improved.

[0033] In this embodiment, as Figure 1 and Figure 4 As shown, the fixing screw 304 forms a through connection structure with the fixing hole 307 through the fixing groove 303, and the fixing nut 305 forms a close-fitting connection structure by threading the two ends of the fixing screw 304 and the two sides of the fixing rod 302. By setting the fixing screw 304 and fixing nut 305 to fix the telescopic distance of the telescopic rod 306, it is easy to adjust according to the lifting distance of the lifting bracket 201, improve the adaptability of the telescopic rod 306, thereby improving the auxiliary support effect of the lifting bracket 201, improving the stability of the water-jet drilling machine during construction, and facilitating tunnel construction.

[0034] The usage and advantages of this utility model: The angle-adjustable multi-head water-grinding drill operates as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the construction workers first move the water-powered drilling rig to the area to be constructed. Then, they rotate the locking lever 103 to lock the caster 102, and simultaneously start the adjusting motor 107 to drive the limiting ring 109 on the threaded shaft 108 to move up and down within the limiting groove 106. This, in conjunction with the limiting rod 1010 externally connected to the limiting ring 109, drives the support rod 1011 to move up and down, ensuring that one end of the support rod 1011 connected to the limiting rod 1010 is in contact with the ground, thus supporting the movable base 101. Next, the hydraulic lifting assembly 104 is activated to lift the lifting bracket 201 to a suitable construction area, aligning the docking seat 202 with the wall. Simultaneously, a fixing screw 304 passes through the fixing groove 303 in the fixing rod 302 and connects with the lifting bracket. The telescopic rod 306 connected to one end of the bottom of the frame 201 is passed through the fixing hole 307 and fixed with the fixing nut 305. Finally, according to the drilling requirements, the hydraulic telescopic component 206 is activated to drive the construction support 209 to adjust the drilling distance to both sides. The scissor rod components 208 on both sides of the hydraulic telescopic component 206 are used for limiting. At the same time, the traction motor 203 is activated to drive the construction support 209 connected to the traction seat 204 to rotate under the action of the rotating support 205, thereby performing drilling operations in the arc position. After the adjustment is completed, the water-grinding drilling machine body 2010 is started to perform drilling operations in the corresponding position. The hydraulic telescopic component 206 and the traction motor 203 are adjusted in sequence to adjust the corresponding drilling position, thus completing the tunnel construction requirements.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
