Description

Technical Field

[0001] This application relates to the field of cable trench drilling devices, and in particular to an automatic drilling robot for highway cable trenches. Background Technology

[0002] In the construction and maintenance of infrastructure such as highways, cable trenches are critical facilities that carry and protect power and communication lines. Typically, regular holes need to be drilled into the concrete guardrails of the cable trenches to install cable supports or fasteners. Currently, this drilling work still relies heavily on traditional manual methods.

[0003] Specifically, construction workers must wield heavy-duty electric hammers in confined workspaces, maintaining unnatural postures such as looking up or bending over for extended periods while working at heights on hard concrete surfaces. This traditional method has several inherent drawbacks: First, it is extremely inefficient. Workers need to repeatedly perform actions such as measuring, positioning, and drilling, limiting the number of holes a shift can complete daily, severely restricting the overall construction progress. Second, it is extremely labor-intensive and carries high safety risks. The strong impact and vibration generated by the heavy-duty electric hammers can easily lead to worker fatigue, causing damage to muscles and bones and posing a risk of injury from slippage. Furthermore, the work sites are often located at the edges of trenches, further increasing the risk of falls from heights. Moreover, the drilling quality is difficult to guarantee, relying entirely on the worker's experience and physical strength, easily resulting in uneven hole spacing, inconsistent hole depths, and verticality deviations. These issues directly affect the installation quality and neatness of subsequent cable supports, creating potential hazards for the long-term safe operation of the line.

[0004] Therefore, the lack of existing automated equipment that can replace manual labor and is specifically designed for such scenarios has made cable trench drilling a bottleneck in the construction process. There is an urgent need for an efficient, precise, and safe automated solution to completely change this situation. Summary of the Invention

[0005] This application provides an automatic drilling robot for highway cable trenches, which solves the problem of time-consuming and labor-intensive manual drilling of cable trenches in the prior art, and achieves the purpose of improving the drilling efficiency of cable trenches and improving the construction environment for construction personnel.

[0006] In a first aspect, embodiments of the present invention provide an automatic drilling robot for highway cable trenches, comprising: a movable support, U-shaped, the open end of which covers the surface of the concrete guardrail of the cable trench; a first roller mechanism evenly distributed on the inner wall of the open end of the movable support; a movable support disposed at one end of the movable support near the cable trench, the movable support moving vertically along the end wall of the movable support; an electric hammer assembly installed at the bottom of the movable support, the drilling end of the electric hammer assembly facing the movable support; an electric hammer height adjustment assembly, the bottom end connected to the movable support, the top end threadedly connected to the movable support; and a second roller mechanism evenly distributed on the side of the movable support near the movable support.

[0011] In one possible implementation, the first roller mechanism further includes a servo motor, which is installed inside the opening of the L-tube and is positioned near the top surface of the concrete guardrail.

[0012] In one possible implementation, a counterweight plate is provided at the end of the L-tube away from the first vertical tube. The counterweight plate is located on the side of the L-tube away from the concrete guardrail, and the surface of the counterweight plate is used to place counterweight blocks.

[0013] In one possible implementation, the base plate surface is provided with a plurality of third vertical tubes spaced apart. The electric hammer assembly includes: a drilling motor and a motor mounting mechanism; wherein the motor mounting mechanism is rotatably mounted between a set of spaced-apart third vertical tubes; the drilling motor is mounted on the motor mounting mechanism; and an angle adjustment mechanism, provided in two sets, the two sets of angle adjustment mechanisms being respectively mounted between another set of spaced-apart third vertical tubes; wherein the output end of the angle adjustment mechanism is drivenly connected to the motor mounting mechanism and is used to drive the motor mounting mechanism to swing around the mounting point of the third vertical tube.

[0014] In one possible implementation, the motor mounting mechanism includes: a first rotating shaft, rotatably mounted at both ends between the two third vertical pipes; a mounting plate, one end of which is fixedly connected to the first rotating shaft; a first swing arm, disposed on one side of the mounting plate, one end of which is fixedly connected to the first rotating shaft; wherein the axis of the first swing arm forms an angle with the plane of the mounting plate; the end of the first swing arm away from the first rotating shaft is drivenly connected to the angle adjustment mechanism; a guide rail, disposed on the surface of the mounting plate; wherein the drilling motor is slidably mounted on the surface of the guide rail; a telescopic cylinder, disposed at the end of the drilling motor near the first rotating shaft, the telescopic cylinder being connected to a drilling air source pipe; a slag collection box, disposed on the side of the mounting plate away from the drilling motor; wherein the inlet of the slag collection box is located near the drill bit of the drilling motor, one end of the feeding channel is connected to the inlet, and the other end is connected to the end of the slag collection box away from the inlet; the slag collection box pipe is connected to a negative pressure air source.

[0015] In one possible implementation, the angle adjustment mechanism includes: a sleeve, the outer wall of which is rotatably disposed at the end of the first rocker arm away from the first rotating shaft; the inner wall of the sleeve is provided with an internal thread; a threaded rod, circumferentially threaded to the inner wall of the sleeve; a mounting base, disposed on the side of the threaded rod away from the first rocker arm; wherein the threaded rod is rotatably mounted on the side of the mounting base near the first rocker arm; one end of the mounting base is rotatably mounted on the outer wall of the third vertical pipe; a drive motor, disposed on the end of the mounting base near the drilling motor, and the output shaft is connected to the end wall of the threaded rod; an extension frame, disposed on the end of the mounting base near the drilling motor; and a negative pressure suction cup, mounted on the end of the extension frame away from the mounting base; wherein the negative pressure suction cup is connected to a negative pressure air source pipe.

[0016] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0017] During operation, the operator first places the U-shaped movable support frame, with its open end straddling the concrete guardrail of the cable trench. At this point, the first roller mechanism, evenly distributed on the inner wall of the open end of the movable support frame, immediately makes close contact with the side of the concrete guardrail. This first roller mechanism constitutes the main load-bearing and guiding system for the longitudinal movement of the equipment on the concrete guardrail, enabling the entire robot to move easily and stably along the trench wall.

[0018] Once the equipment is moved to the predetermined drilling position, the drilling process begins. By tightening the electric hammer height adjustment component, whose top end is threaded to the moving bracket and whose bottom end is connected to the movable bracket, the movable bracket can be driven to move precisely vertically along the end wall of the moving bracket. The electric hammer assembly, mounted at the bottom of the movable bracket, rises and falls synchronously, thus accurately positioning its drilling end to the preset height. During this process, the second roller mechanism, evenly distributed on the side of the movable bracket closest to the moving bracket, is pressed against the other inner side of the concrete guardrail. It works in conjunction with the first roller mechanism to form a stable frame that clamps the electric hammer assembly from both inside and outside, effectively suppressing vibration and shaking during operation.

[0019] After positioning is completed, the electric hammer assembly is started, and its drilling end is directed toward the concrete guardrail for high-speed impact drilling. After one hole is completed, the electric hammer assembly stops working, and the operator can easily push the equipment to move to the next hole position through the first roller mechanism. The above process is repeated to achieve continuous and batch automated drilling.

[0020] The traditional heavy and high-risk operation mode that relied entirely on manual hand-held electric hammers has been transformed into a mechanized and automated process, significantly improving drilling efficiency and directly liberating workers from high-intensity physical labor and harsh working environments. The height is controlled by the precision thread transmission of the electric hammer height adjustment component, combined with a rigid closed-loop support system composed of the first roller mechanism and the second roller mechanism, which effectively overcomes the inherent shaking and offset of hand-held operation and ensures that the verticality and position coordinates of each drill hole are highly consistent.

[0051] Example 1

[0052] Please see Figures 1-9An automatic drilling robot for highway cable trenches includes: a U-shaped movable support 100, the open end of which covers the surface of a concrete guardrail 200 of the cable trench; a first roller mechanism 300 evenly distributed on the inner wall of the open end of the movable support 100; a movable support 400 located at one end of the movable support 100 near the cable trench, the movable support 400 moving vertically along the end wall of the movable support 100; an electric hammer assembly 500 installed at the bottom of the movable support 400, the drilling end of the electric hammer assembly 500 facing the movable support 100; an electric hammer height adjustment assembly 600, the bottom end of which is connected to the movable support 400, and the top end of which is threadedly connected to the movable support 100; and a second roller mechanism 700 evenly distributed on the side of the movable support 400 near the movable support 100.

[0053] In the above embodiment, during operation, the operator first places the U-shaped movable support 100 across the concrete guardrail 200 of the cable trench from its open end. At this time, the first roller mechanism 300, evenly distributed on the inner wall of the open end of the movable support 100, immediately comes into close contact with the side of the concrete guardrail 200. This first roller mechanism 300 constitutes the main load-bearing and guiding system for the longitudinal movement of the equipment on the concrete guardrail 200, enabling the entire robot to move easily and stably along the trench wall.

[0054] Once the equipment is moved to the predetermined drilling position, the drilling process begins. By tightening the electric hammer height adjustment component 600, whose top end is threaded to the movable support 100 and whose bottom end is connected to the movable support 400, the movable support 400 can be driven to move precisely vertically along the end wall of the movable support 100. The electric hammer assembly 500, mounted at the bottom of the movable support 400, rises and falls synchronously, thus precisely positioning its drilling end to the preset height. During this process, the second roller mechanism 700, evenly distributed on the side of the movable support 400 near the movable support 100, is pressed against the other inner side of the concrete guardrail 200. It cooperates with the first roller mechanism 300 to form a stable frame with internal and external clamping, effectively suppressing the vibration and shaking of the electric hammer assembly 500 during operation.

[0055] After positioning is completed, the electric hammer assembly 500 is started, and its drilling end faces the concrete guardrail 200 to perform high-speed impact drilling. After one hole is completed, the electric hammer assembly 500 stops working, and the operator can easily push the equipment to move to the next hole position through the first roller mechanism 300. The above process is repeated to achieve continuous and batch automated drilling.

[0056] The traditional heavy and high-risk operation mode that relies entirely on manual hand-held electric hammers has been transformed into a mechanized and automated process, significantly improving drilling efficiency and directly liberating workers from high-intensity physical labor and harsh working environments. The height is controlled by the precision thread transmission of the electric hammer height adjustment component 600, combined with the rigid closed-loop support system composed of the first roller mechanism 300 and the second roller mechanism 700, which effectively overcomes the inherent shaking and offset of hand-held operation and ensures that the verticality and position coordinates of each drill hole are highly consistent.

[0057] Example 2

[0058] Please see Figures 1-9 The movable support 100 includes: two sets of L-tubes 110, one end of each set of L-tubes 110 being located on the side of the cable trench away from the trench; two sets of first vertical tubes 120, the two sets of first vertical tubes 120 being spaced apart at the end of the L-tubes 110 near the trench; and the movable support 400 sliding within each of the first vertical tubes 120.

[0059] In the above embodiment, the movable support 100 consists of a core frame composed of two sets of L-tubes 110 and two sets of first vertical tubes 120. During operation, one end of each of the two sets of L-tubes 110 is mounted on the side of the cable trench away from the trench, allowing the equipment to sit stably on the concrete guardrail 200. When drilling is required, the movable support 400 is precisely slid vertically within the two sets of first vertical tubes 120 by driving the electric hammer height adjustment component 600. The electric hammer component 500, installed at the bottom of the movable support 400, rises and falls synchronously to accurately position the drilling height. The second roller mechanism 700, evenly distributed on the movable support 400, is in close contact with the inner wall of the concrete guardrail 200, working in conjunction with the first roller mechanism 300 to form a stable clamping effect. After positioning is completed, the electric hammer component 500 is activated to impact and drill. After completion, the equipment can be moved to the next work station along the guardrail via the first roller mechanism 300. The frame-type movable support 100, composed of L-tube 110 and first vertical tube 120, forms a high-rigidity main structure that can effectively resist the strong impact and vibration of the electric hammer assembly 500 during operation, ensuring that the equipment will not deform or shake during long-term operation. The movable support 400 slides directly within the two sets of first vertical tubes 120, providing precise and stable vertical guidance, fundamentally avoiding swaying during the drilling process, and ensuring the verticality and positional accuracy of the drilling.

[0060] Example 3

[0061] Please see Figures 1-9The movable support 400 includes: a plurality of second vertical tubes 410, which are slidably sleeved on the outer circumferential wall of each first vertical tube 120; and a base plate 420, which is disposed at the bottom end of each second vertical tube 410, with each second vertical tube 410 evenly distributed at each top corner of the base plate 420.

[0062] In the above embodiment, the movable support 400 consists of a base plate 420 and multiple second vertical tubes 410. During operation, the operator drives the entire movable support 400 to rise and fall by rotating the electric hammer height adjustment assembly 600, which is threadedly connected to the movable support 100. Specifically, multiple second vertical tubes 410 are slidably sleeved on the circumferential outer wall of the corresponding first vertical tube 120. This sleeved connection provides precise and stable guidance for the vertical movement of the movable support 400. The electric hammer assembly 500 mounted on the base plate 420 moves synchronously to achieve precise positioning of the drilling height. In particular, each second vertical tube 410 is evenly distributed at each of the top corners of the base plate 420, forming a stable column system with the first vertical tube 120, ensuring that the base plate 420 remains horizontal when subjected to impact. The sliding sleeved structure of multiple second vertical tubes 410 and multiple first vertical tubes 120 forms a multi-point, large-area contact guide, effectively preventing the movable support 400 from deflecting and jamming during lifting and drilling, and ensuring the verticality of the impact direction of the electric hammer assembly 500.

[0063] Example 4

[0064] Please see Figures 1-9 Both the first roller mechanism 300 and the second roller mechanism 700 are composed of multiple casters 310; wherein each caster 310 is evenly distributed on the side of the L-tube 110 and the second vertical tube 410 near the surface of the concrete guardrail.

[0065] In the above embodiment, the movable support 100 consists of two sets of L-tubes 110 and a first vertical tube 120 forming a basic frame, straddling the concrete guardrail 200. The movable support 400 is designed with multiple second vertical tubes 410 slidingly fitted outside the first vertical tube 120, driven by the electric hammer height adjustment component 600 to achieve precise vertical lifting. The first roller mechanism 300 and the second roller mechanism 700 are both composed of multiple casters 310. These casters 310 are evenly distributed and installed on the side of the L-tubes 110 and the second vertical tubes 410 near the surface of the concrete guardrail 200. When the equipment needs to move, these casters 310 distributed at key structural nodes form multi-point, flexible contact with various surfaces of the concrete guardrail 200, allowing the robot to easily adjust its position longitudinally and slightly laterally. During drilling, the casters 310 press against the guardrail under pressure, forming a stable whole with the tubular frame, effectively suppressing vibration.

[0066] Example 5

[0067] Please see Figures 1-9 The movable support 100 further includes: a top plate 130, disposed on the surface of the L-tube 110 near the end of the cable trench; the electric hammer height adjustment assembly 600 includes: a screw 610, one end of which is rotatably connected to the center of the surface of the base plate 420, and the top end of which passes through the surface of the top plate 130; a nut 620, which is fixedly installed on the surface of the top plate 130, and the top end of the screw 610 is threadedly connected to the nut 620.

[0068] In the above embodiment, the main frame of the robot is composed of a movable support 100, including two sets of L-tubes 110 mounted on the concrete guardrail 200, two sets of first vertical tubes 120, and a top plate 130 connected to one end of the L-tubes 110 near the trench. The movable support 400 is slidably fitted onto the outer circumferential wall of each first vertical tube 120 via its multiple second vertical tubes 410, and is connected as a whole by a base plate 420 located at the center. The bottom end of the screw 610 of the electric hammer height adjustment component 600 is rotatably connected to the center of the surface of the base plate 420, and its top end passes upward through the surface of the top plate 130. The nut 620, which is fixedly installed on the surface of the top plate 130, and the screw 610 form a threaded pair. When the operator rotates the screw 610, the screw 610 will generate a vertical displacement under the constraint of the nut 620, thereby directly driving the entire movable support 400 to rise and fall smoothly. The electric hammer assembly 500 installed on the base plate 420 will then accurately reach the predetermined height. At the same time, the casters 310, which are evenly distributed on the L-tube 110 and the second vertical tube 410, will always be in close contact with the surface of the concrete guardrail 200, providing stable support. After positioning is completed, the electric hammer assembly 500 can be started to automatically drill holes.

[0069] Example 6

[0070] Please see Figures 1-9 The first roller mechanism 300 further includes a servo motor 320, which is installed inside the opening of the L-tube 110 and is located near the top surface of the concrete guardrail 200.

[0071] In the above embodiment, the first roller mechanism 300, based on the multiple casters 310, is equipped with a servo motor 320. The servo motor 320 is installed in the opening of the L-tube 110, with its output end positioned close to the top surface of the concrete guardrail 200 to drive specific casters 310. The operator can send commands to the servo motor 320 via remote control. As a mature and conventional control element, the servo motor 320, upon receiving a wireless signal, will rotate its output shaft at a precise angle, thereby driving the robot to move automatically along the concrete guardrail 200, achieving autonomous movement between holes. This changes the equipment from manual pushing to electric movement. The operator no longer needs to frequently get on and off the equipment or follow along the ditch; they can simply remotely control the robot from a safe position to move it to the next hole on the concrete guardrail 200, greatly simplifying the operation process and improving continuous operation efficiency.

[0072] Example 7

[0073] Please see Figures 1-9 The L-tube 110 is provided with a counterweight plate 140 at one end away from the first vertical tube 120. The counterweight plate 140 is located on the side of the L-tube 110 away from the concrete guardrail 200, and the surface of the counterweight plate 140 is used to place counterweight blocks.

[0074] In the above embodiment, a counterweight plate 140 is provided at the end of the L-tube 110 away from the first vertical tube 120. The counterweight plate 140 is located on the side of the L-tube 110 away from the concrete guardrail 200. The operator can place a counterweight block of a specific weight on the surface of the counterweight plate 140 as needed. Through the lever principle, the downward pressure of the equipment on the top surface of the concrete guardrail 200 is significantly increased. This pressure is directly transmitted to the universal wheel 310 driven by the servo motor 320 installed in the opening of the L-tube 110 and close to the top surface of the concrete guardrail 200, thereby improving the adhesion of the drive wheel and preventing the multiple wheels of the servo motor 320 from slipping when rotating.

[0075] Example 8

[0076] Please see Figures 7-9 The base plate 420 has a plurality of third vertical tubes 530 spaced apart on its surface. The electric hammer assembly 500 includes: a drilling motor 510 and a motor mounting mechanism 520; wherein the motor mounting mechanism 520 is rotatably mounted between a group of spaced third vertical tubes 530; the drilling motor 510 is mounted on the motor mounting mechanism 520; and two sets of angle adjustment mechanisms 540 are provided, each set of which is mounted between another group of spaced third vertical tubes 530; wherein the output end of the angle adjustment mechanism 540 is drivenly connected to the motor mounting mechanism 520 and is used to drive the motor mounting mechanism 520 to swing around the mounting point of the third vertical tube 530.

[0077] In the above embodiment, when the drilling robot moves along the cable trench, in order to avoid the drill bit of the drilling motor 510 from colliding with the protrusions on the outer wall of the cable trench, it is necessary to retract the drill bit of the drilling motor 510 during its movement. When retracting, the angle adjustment mechanism 540 works, and through its output end, it drives the motor mounting mechanism 520 to swing around the connection point with the third vertical pipe 530, so that the motor mounting mechanism 520 drives the drilling motor 510 to swing, and finally set the drill bit of the drilling motor 510 downward.

[0078] Example 9

[0079] Please see Figures 7-9 The motor mounting mechanism 520 includes: a first rotating shaft 521, rotatably mounted at both ends between the two third vertical pipes 530; a mounting plate 522, one end of which is fixedly connected to the first rotating shaft 521; a first rocker arm 523, located on one side of the mounting plate 522, one end of which is fixedly connected to the first rotating shaft 521; wherein the axis of the first rocker arm 523 forms an angle with the plane of the mounting plate 522; the end of the first rocker arm 523 away from the first rotating shaft 521 is drivenly connected to the angle adjustment mechanism 540; and a guide rail 524, located on the surface of the mounting plate 522. The drilling motor 510 is slidably mounted on the surface of the guide rail 524; a telescopic cylinder 525 is located at one end of the drilling motor 510 near the first rotating shaft 521, and the telescopic cylinder 525 is connected to the drilling air source pipe; a slag collection box 526 is located on the side of the mounting plate 522 away from the drilling motor 510; wherein the feed inlet 527 of the slag collection box 526 is located near the drill bit of the drilling motor 510, one end of the feed channel is connected to the feed inlet 527, and the other end is connected to the end of the slag collection box 526 away from the feed inlet 527; the slag collection box 526 is pipe-connected to a negative pressure air source.

[0080] In the above embodiment, the mounting plate 522 is installed between the two third vertical pipes 530 via a first rotating shaft 521. Both ends of the first rotating shaft 521 are rotatably connected to the third vertical pipes 530. When the angle adjustment mechanism 540 drives one end of the first swing rod 523 to move, the first swing rod 523 swings around the axis of the first rotating shaft 521. Since the first swing rod 523 and the first rotating shaft 521 are fixedly connected, the first swing rod 523 drives the first rotating shaft 521 and the mounting plate 522 to swing around the axis of the first rotating shaft 521. When drilling is required, the first swing rod 523 swings towards the side closer to the drilling motor 510 at the lower part of the first rotating shaft 521 until it drives the drilling motor 510 to swing to a horizontal state for drilling. During the swinging process of the mounting plate 522, the slag collection box 526 located at the lower part of the mounting plate 522 swings to a horizontal state, causing the surface of the slag collection box 526 to... The feed inlet 527 is located below the drill bit of the drilling motor 510. When the drilling motor 510 starts drilling, the negative pressure air source is activated to evacuate the slag collection box 526, allowing the feed channel to suck up the slag extracted by the drill bit through the feed inlet 527. The slag enters the slag collection box 526 for storage through the feed channel. The end of the feed channel away from the feed inlet 527 is located at the end of the slag collection box 526 away from the feed inlet 527. When the angle adjustment mechanism 540 drives the mounting plate 522 to approach a vertical state, the slag in the slag collection box 526 slides towards the end of the slag collection box 526 closer to the feed inlet 527, causing the slag to accumulate in the slag collection box 526 towards the drill bit. After each drilling operation, the slag in the slag collection box 526 will slide and accumulate in this position to prevent the slag from accumulating at the feed inlet 527 and clogging it.

[0081] Example 10

[0082] Please see Figures 7-9 The angle adjustment mechanism 540 includes: a sleeve 541, the outer wall of which is rotatably disposed at the end of the first rocker arm 523 away from the first rotating shaft 521; the inner wall of the sleeve 541 is provided with an internal thread; a threaded rod 542, which is circumferentially threaded to the inner wall of the sleeve 541; a mounting base 543, disposed on the side of the threaded rod 542 away from the first rocker arm 523; wherein the threaded rod 542 is rotatably mounted on the side of the mounting base 543 near the first rocker arm 523; one end of the mounting base 543 is rotatably mounted on the outer wall of the third vertical pipe 530; a drive motor 544, disposed on the end of the mounting base 543 near the drilling motor 510, and the output shaft is connected to the end wall of the threaded rod 542; an extension frame 545, disposed on the end of the mounting base 543 near the drilling motor 510; and a negative pressure suction cup 546, mounted on the end of the extension frame 545 away from the mounting base 543; wherein the negative pressure suction cup 546 is connected to a negative pressure air source pipe.

[0083] In the above embodiments, in order to improve the vibration problem of the drilling motor 510 during operation, when the drilling motor 510 is working, the telescopic cylinder 525 is inflated and pushes the drilling motor 510 to move continuously towards the side closer to the outer wall of the cable trench, pushing the drill bit into the concrete structure. During the swinging process of the angle adjustment mechanism 540 driving the drilling motor 510, the output shaft of the drive motor 544 rotates and drives the threaded rod 542 to rotate, so that the threaded rod 542 drives the sleeve 541 to move on its outer wall. As the sleeve 541 moves towards the drive motor 544, it drives the first swing rod 523 to swing, thereby achieving the purpose of driving the drilling motor 510 to swing in the horizontal direction.

[0084] During this process, as the threaded rod 542 rotates, the distance between the end of the threaded rod 542 and the first swing rod 523 continuously increases, causing the threaded rod 542 to drive the mounting base 543 to swing around the installation position of the mounting base 543 and the third vertical pipe 530. This causes the end of the mounting base 543 near the drive motor 544 to drive the extension frame 545 to swing towards the cable trench until the extension frame 545 drives the negative pressure suction cup 546 to be perpendicular to the outer wall of the concrete structure of the cable trench. The negative pressure air source is then activated to evacuate the negative pressure suction cup 546, causing the negative pressure suction cup 546 to be sucked onto the outer wall of the cable trench and fixed while the drilling motor 510 is working.
