Description
Technical Field
[0001] This utility model relates to the field of bridge construction, specifically an electric bridge side drilling tool. Background Technology
[0002] During the construction of highway bridges, it is necessary to install pipe box supports for electromechanical systems on the exterior facade of the highway bridge. Since highway bridge construction is different from that of ordinary urban viaducts, highway bridges are mostly erected in the field and are quite high. Construction workers need to hang the hanging basket on the edge railing of the bridge and stand inside the hanging basket to drill holes in the exterior facade of the bridge to install the pipe box supports.
[0003] When construction workers stand inside the hanging basket to carry out construction, the hanging basket needs to be moved intermittently along the length of the bridge. With the existing hanging basket, it is difficult to move because the construction workers are on the outside. Moreover, the construction workers standing inside the hanging basket cannot operate it. The movement of the hanging basket can only be controlled by the construction workers on the bridge. This is inconvenient for the construction workers standing inside the hanging basket, increases safety hazards, greatly reduces the construction progress, and causes idle workers, which in turn increases construction costs.
[0004] When construction workers stand inside the hanging basket to perform hole-making operations, they generally use hand tools, which not only greatly increases the labor intensity of the construction workers, but also results in inconsistent hole-making quality. The height, depth, and levelness of the holes cannot be uniform, which affects the installation effect of the support and has many defects.
[0005] Therefore, there is an urgent need for an electric bridge side drilling machine to solve the above-mentioned technical problems. Utility Model Content

[0026] See Figures 1 to 4 As shown, the technical solution of this utility model is as follows:
[0027] An electric bridge side drilling tool includes a tool frame, which includes a suspension frame 1 and a support frame 2. The suspension frame 1 is provided with a downward-facing suspension part 3.
[0028] The suspension frame 1 includes two L-shaped connecting rods, which are square tubes. The two L-shaped connecting rods are spaced apart from each other, and the right-angle openings of the two L-shaped connecting rods are both facing downwards. A side connecting plate is connected to one end of the two L-shaped connecting rods. The side connecting plate is a steel plate and is welded between the two L-shaped connecting rods. A vertical connecting rod is connected to the other end of the two L-shaped connecting rods. A support cover plate is welded to both the two L-shaped connecting rods and the two vertical connecting rods. The support cover plate is fixed in the horizontal direction and is located at the top of the suspension part 3.
[0029] The support frame 2 is welded to the right side of the suspension frame 1. The support frame 2 includes two short connecting diagonal rods, both of which are square tubes. The two short connecting diagonal rods are welded at the right angle between the L-shaped connecting rod and the vertical connecting rod. Long connecting diagonal rods are welded at an angle on the right side of the vertical connecting rod. Both long connecting diagonal rods are square tubes. Vertical connecting rods are welded to the other end of the two long connecting diagonal rods. The vertical connecting rods are square tubes. A support base plate 4 is welded to the lower ends of the two vertical connecting rods and the two vertical connecting rods. A support guard plate 10 is set together in the lower part between the two vertical connecting rods, the two vertical connecting rods, the adjacent vertical connecting rods and the vertical connecting rod. A construction recess 11 is reserved on the support guard plate 10. The construction recess 11 is located on the side close to the suspension part 3.
[0030] A drive and travel assembly is installed on the suspension frame 1, and a drilling assembly is installed on the support frame 2.
[0031] The drilling assembly is mounted on the support base plate 4. The drilling assembly includes a T-shaped push plate 5, which comprises a sliding plate and a vertical plate. The sliding plate is slidably mounted on the support base plate 4. A groove is machined on the support base plate 4. A slider, adapted to the groove and reciprocating along the groove, is machined on the bottom surface of the sliding plate. The vertical plate is vertically welded to the middle of the top surface of the sliding plate. A displacement drive motor 6 is fixedly mounted on the support plate. A displacement screw 7 is driven and connected to the displacement drive motor 6. The sliding plate is connected to the displacement screw 7. The sliding plate reciprocates along the length of the displacement screw 7 on the support base plate 4. Fixed connecting rods 17 are installed on the left and right sides of the displacement screw 7 on the sliding plate. The lengths of the two fixed connecting rods 17 are the same as the length of the displacement screw 7. The fixed connecting rods 17 all penetrate vertically through the sliding plate. Both fixed connecting rods 17 are vertically fixed to the inner side of the supporting guard plate 10, and both fixed connecting rods 17 are located above the supporting base plate 4, ensuring the stability of the T-shaped push plate 5. Two drilling drive motors 8 are installed on the side of the vertical plate near the displacement drive motor 6. The two drilling drive motors 8 are spaced vertically along the height direction. Each drilling drive motor 8 is connected to a drilling bit 9 that penetrates vertically through the vertical plate. A first start / stop switch is connected to the displacement drive motor 6 and is installed on the supporting cover plate, so as to control the start and stop of the displacement drive motor 6. A control module is connected to the drilling drive motor 8, and a handheld control terminal is connected to the control module, so as to control the depth, height, and levelness of the hole drilled by the drilling bit 9 through the handheld control terminal.
[0032] The driving and walking assembly includes a walking drive motor 12, which is mounted on the top surface of the support cover plate. A through hole is machined in the middle of the support cover plate, and the walking drive motor 12 is located at the through hole. A walking drive wheel 13 is installed below the support cover plate, passing through the through hole and connected to the walking drive motor 12. The walking drive motor 12 and the walking drive wheel 13 both use vertical steering wheels of model MDL230-1.3 from Hangzhou Wuzhong brand. The walking drive motor 12 drives the walking drive wheel 13 to move. Two driven wheels 14 are installed on the left and right sides of the walking drive wheel 13, forming a four-wheel drive assembly. The driven wheels 14 are all installed on the bottom surface of the support cover plate. Two auxiliary wheels 15 are installed on the inner sides of the side connecting plate and the support guard plate 10, which are opposite to each other. The two auxiliary wheels 15 on the support guard plate 10 are located on both sides of the construction recess 11. The four auxiliary wheels 15 and the four driven wheels 14 assist the walking drive wheel 13 to walk, so as to reduce the weight borne by the walking drive wheel 13 and reduce the wear of the walking drive wheel 13. A second start-stop switch is connected to the walking drive motor 12. The second start-stop switch is installed on the support cover plate, so as to control the start and stop of the walking drive motor 12.
[0033] Two protective connecting rods 16 are welded together on the upper part of the two vertical connecting rods. The two protective connecting rods 16 are spaced apart vertically and parallel to each other. Both protective connecting rods 16 are made of steel plates bent into a slight arc shape.
[0034] A bracket 18 is connected to the drive wheel 13. Ten magnetic nails 19 are installed on the side of the drive wheel 18. The ten magnetic nails 19 are arranged in a circular array around the center of the drive wheel 13. Hall sensors 20 adapted to the ten magnetic nails 19 are installed on the bracket 18. Each time a magnetic nail 19 approaches the Hall sensor 20, the Hall sensor 20 generates a signal. Since a total of ten magnetic nails 19 are installed on the drive wheel 13, the Hall sensor 20 will sense ten signals, corresponding to one rotation of the drive wheel 13. Before this, the circumference of the drive wheel 13 can be measured or calculated. If the drive wheel 13 has a circumference of 20cm, then 10 signals represent a forward movement of 20cm, and 100 signals represent a forward movement of 2m. Therefore, when controlling the drilling tool to move forward, it is only necessary to calibrate the Hall sensor 20 to detect 100 signals.
[0035] An ultrasonic ranging sensor is installed on the side of the vertical plate away from the drilling drive motor (the ultrasonic ranging sensor is not shown in the attached diagram). The ultrasonic ranging sensor emits an ultrasonic wave signal to the outer side of the bridge crash barrier. The sound wave is reflected back to the ultrasonic receiving module through the outer side of the bridge crash barrier. The distance is calculated using the time difference between the emission and reception times, and thus the depth of the drill bit into the bridge crash barrier is calculated. Let: drill bit length L, length into the bridge crash barrier l, emission time t0, reception time t1, sound wave velocity v, l = L-(t1-t0)*v / 2. The distance l into the bridge crash barrier is then calculated.
[0036] When in use, place the electric bridge side drilling tool on the bridge crash barrier. After the electric bridge side drilling tool is installed securely, power on the displacement drive motor 6, the travel drive motor 12, and the drilling drive motor 8. Set the drilling construction components, drilling depth, height, and level on the handheld control terminal. Then, control the travel drive motor 12 to move the electric bridge side drilling tool to the designated position, control the displacement drive motor 6 to approach the outer side of the bridge crash barrier, and control the drilling drive motor 8 to drive the drilling bit 9 to perform drilling construction.
[0037] This utility model includes a tool frame, a drive and travel assembly mounted on the tool frame, and a drilling assembly mounted on the tool frame. A suspension part 3 is provided on the tool frame, allowing the bridge crash barrier to be placed within the suspension part 3, thus suspending the tool frame on the bridge crash barrier. The drive and travel assembly moves the tool frame along the bridge crash barrier, eliminating the need for additional personnel to assist in its movement, saving manpower and improving the tool frame's mobility. The drilling assembly enables automatic drilling on the bridge side, reducing manpower input and eliminating the need for construction personnel to perform high-altitude drilling operations on the outside of the bridge crash barrier, thus reducing construction costs and risks. It ensures uniform height, depth, and levelness of the drilling, guaranteeing the quality of the drilling and the installation effect of the support, effectively saving drilling time and improving the construction progress of the pipe box support.
