Description

Technical Field

[0001] This utility model relates to the field of power transmission tower technology, specifically to a drilling device for steel materials of power transmission towers. Background Technology

[0002] Transmission towers are tall structures that are very sensitive to tilting deformation and have high requirements for uneven settlement of the foundation. The common structural forms of transmission tower foundations include independent foundations, spread foundations and pile foundations. The main structural form of transmission towers is steel structure. During the manufacturing process of transmission towers, drilling equipment is usually used to drill holes in the steel used for transmission towers.

[0003] A search of the China Patent Network revealed a patent (publication number: CN 221817362U) that discloses a drilling device for steel transmission towers. By setting a sliding rod and an electromagnetic sleeve, the position of the drill bit can be adjusted in the horizontal direction, which means that the drilling position on the surface of the steel transmission tower can be adjusted in the horizontal direction, thus bringing convenience to the drilling process of steel transmission towers.

[0004] However, the above technical solution still has certain defects. When clamping and positioning the steel of the power transmission tower, the steel is first placed in two sets of clamps, and then the external force of rotation is manually applied to the fixing bolt to make the fixing plate lower so that the steel can be clamped. The thinner the steel, the more turns the fixing bolt needs to be rotated, which leads to a longer clamping time and low drilling efficiency. Therefore, a drilling device for power transmission tower steel is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a drilling device for steel transmission towers to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for steel materials of power transmission towers, including a base, a drilling platform mounted on the top of the base, a frame fixed near the edge of the top of the base, and a drilling component mounted inside the frame directly above the drilling platform.

[0007] Two sets of U-frames for clamping steel are mounted on the top of the drilling table and near the left and right edges. A double-headed motor is embedded in the front and rear surfaces of the base. Both ends of the double-headed motor are provided with lead screws that are rotatably connected to the drilling table. A driven sleeve is threaded onto the outer wall of each set of lead screws, and the outer wall of the driven sleeve is fixed to a vertical plate that drives the two sets of U-frames to move closer to each other. A driven strip is slidably provided on the upper inner wall of the U-frame. A clearance groove is opened on the outer wall of the U-frame near the frame. A base rod fixed to the side wall of the driven strip is slidably provided in the clearance groove. A trapezoidal block is fixed at the bottom end of the base rod. A notch is opened on the top of the base and at the front and rear edges. A trapezoidal strip that compresses the trapezoidal block and lowers it is mounted on the side wall of the notch.

[0008] As a preferred technical solution, the trapezoidal strip is fixed to the side wall of the notched groove with bolts, and the side wall of the notched groove has multiple sets of bolt holes at equal intervals.

[0009] As a preferred technical solution, the driven bar has an active bar attached to the inner wall of the U-frame at its top. The active bar has a screw shank rotatably connected to the top of the driven bar through its top thread, and the top of the screw shank extends to the top of the U-frame. A channel is provided at the contact position between the U-frame and the screw shank, and the inner diameter of the channel is larger than the outer diameter of the screw shank.

[0010] As a preferred technical solution, the base rod is fitted with two sets of positioning blocks. The upper positioning block is fixed to the base rod and the active bar respectively, and the lower positioning block is movably sleeved on the outer wall of the positioning block and fixed in the clearance groove. A spring is sleeved between the two sets of positioning blocks and on the outer wall of the base rod.

[0011] As a preferred technical solution, the lower inner wall of the U-frame is provided with anti-slip texture.

[0012] As a preferred technical solution, the front and rear surfaces of the base are provided with stroke grooves at the contact positions with the dual-head motor, and the end of the lead screw is rotatably connected to the side wall of the stroke groove.

[0013] As a preferred technical solution, the drilling component includes three sets of positioning rods that are horizontally fixed within the frame. Electromagnetic sleeves are slidably fitted on the outer walls of the three sets of positioning rods, and a drive motor is fitted below the electromagnetic sleeves. The output end of the drive motor is provided with a drill bit for drilling. An electric push rod that drives the drive motor to rise and fall is fitted at the bottom of the electromagnetic sleeve. A housing that is fixed to the telescopic end of the electric push rod is fitted on the outside of the drive motor.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention uses two sets of U-frames to reinforce the steel of the power transmission tower. When the two sets of U-frames are close to each other, the trapezoidal strip pulls the active strip lower, which works in conjunction with the U-frames to reinforce the steel of the power transmission tower. This saves on the operation steps before drilling holes in the steel of the power transmission tower, thereby improving the efficiency of the device in drilling holes in the steel of the power transmission tower. At the same time, the positions of the trapezoidal strip and the active strip can be changed to accommodate power transmission tower steel of different sizes, further expanding the applicability of the device.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A drilling device for steel transmission towers, such as Figures 1 to 6 As shown, it includes a base 100, a punching table 140 is mounted on the top of the base 100, a frame 110 is fixed on the top of the base 100 near the edge, and a punching component 120 is mounted inside the frame 110 directly above the punching table 140.

[0027] Two sets of U-frames 160 for clamping steel are mounted on the top of the drilling table 140 and near the left and right edges. A double-head motor 150 is embedded in the front and rear surfaces of the base 100. Both ends of the double-head motor 150 are provided with lead screws 151 that are rotatably connected to the drilling table 140. A driven sleeve 152 is threaded onto the outer wall of each set of lead screws 151. The outer wall of the driven sleeve 152 is fixed to the upright plate 162 that drives the two sets of U-frames 160 to approach each other. A driven strip 163 is slidably provided on the upper inner wall of the U-frame 160. A clearance groove 165 is opened on the outer wall of the U-frame 160 near the frame 110. A base rod 166 fixed to the side wall of the driven strip 163 is slidably provided in the clearance groove 165. A trapezoidal block 168 is fixed at the bottom end of the base rod 166. A notch 142 is opened on the top of the base 100 and at the front and rear edges. A trapezoidal strip 170 that compresses the trapezoidal block 168 and lowers it is mounted on the side wall of the notch 142.

[0028] The base rod 166 is fitted with two sets of positioning blocks 169. The upper positioning block 169 is fixed to the base rod 166 and the drive bar 161 respectively. The lower positioning block 169 is movably sleeved on the outer wall of the positioning block 169 and fixed in the relief groove 165. A spring 167 is fitted between the two sets of positioning blocks 169 and on the outer wall of the base rod 166.

[0029] The steel material of the power transmission tower that needs to be drilled is placed on top of the drilling table 140, with the bottom ends of both ends of the steel material located on the inner wall of the U-frame 160. At this time, the double-headed motor 150 is controlled to work, and its output end will drive the two sets of lead screws 151 to rotate, pulling the driven sleeve 152 to slide linearly and approach each other on the outer wall of the lead screw 151. At this time, driven by the upright plate 162, the two sets of U-frames 160 will move closer to each other, and the trapezoidal block 168 will move linearly within the notch 142 and will interact with the trapezoidal strip 17. The inclined surface at the bottom of the trapezoidal bar 170 contacts the trapezoidal block 138, which exerts a downward squeezing force on the trapezoidal block 138 together with the base rod 166 at the top. At this time, the active bar 161 and the driven bar 163 below will also lower synchronously. The driven bar 163 will contact the upper surface of the steel and cooperate with the two sets of U-frames 160 that are close to each other to complete the purpose of clamping the placed transmission tower steel. In this way, the drilling component above can be controlled to perform the drilling step.

[0030] When the dimensions and thickness of the steel material of the transmission tower to be drilled change, the trapezoidal strip 170 is loosened and removed manually using tools. The installation position of the trapezoidal strip 170 is then re-determined based on the length of the plate material to meet the purpose of clamping the steel material of the required dimensions.

[0031] Please refer to this carefully. Figure 1 and Figure 2 The trapezoidal strip 170 is fixed to the side wall of the notch 142 with bolts, and multiple sets of bolt holes are equally spaced on the side wall of the notch 142.

[0032] The trapezoidal strip 170 can be repositioned by using bolts to accommodate steel of different lengths.

[0033] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4 The driven bar 163 has a driving bar 161 attached to the inner wall of the U frame 160 at its top. The top of the driving bar 161 is threaded through a screw shank 164 rotatably connected to the top of the driven bar 163. The top of the screw shank 164 extends to the top of the U frame 160. A channel is provided at the contact position between the U frame 160 and the screw shank 164, and the inner diameter of the channel is larger than the outer diameter of the screw shank 164.

[0034] Rotating the lead screw handle 164 can cause the driven bar 163 to lower, which can change the space between the U-frame and the driven bar 163, thereby meeting the purpose of clamping steel of different thicknesses;

[0035] The driven bar 163 has two sets of constraint rods extending through to the top of the driving bar 161. The two sets of constraint rods are located on both sides of the lead screw shank 164. A through hole is provided at the position where the driving bar 161 contacts the constraint rod.

[0036] The constraint rod ensures that the driven bar 163 will not rotate with the lead screw 164, allowing for linear lowering under the constraint of the constraint rod and the through hole.

[0037] Please refer to this carefully. Figure 2 The lower inner wall of the U-frame 160 has anti-slip texture.

[0038] When the two sets of U-frames 160 move relatively close to each other on the top of the drilling table 140, the anti-slip texture increases the coefficient of friction between the frame and the steel, which can prevent the steel from shifting and affecting the subsequent drilling steps.

[0039] Please refer to this carefully. Figure 1 and Figure 2 The front and rear surfaces of the base 100 are provided with stroke grooves 141 at the contact positions with the dual-head motor 150, and the end of the lead screw 151 is rotatably connected to the side wall of the stroke groove 141.

[0040] Space is provided for the installation of the dual-head motor 150 and the lead screws 151 at both ends, so that they can stably drive the two sets of U-frames 160 to move closer together to achieve the purpose of clamping the steel.

[0041] Please refer to this carefully. Figure 1 The drilling component 120 includes three sets of positioning rods 121 that are laterally fixed within the frame 110. Electromagnetic sleeves 122 are slidably mounted on the outer walls of the three sets of positioning rods 121. A drive motor 124 is mounted below the electromagnetic sleeve 122. A drill bit 126 for drilling is provided at the output end of the drive motor 124. An electric push rod 123 that drives the drive motor 124 to rise and fall is mounted at the bottom of the electromagnetic sleeve 122. A housing 125 fixed to the telescopic end of the electric push rod 123 is mounted on the outside of the drive motor 124.

[0042] The bottom of the punching station 140 is provided with a sliding component 130 that is mounted on the top of the base 100;

[0043] First, disconnect the circuit of the electromagnetic sleeve 122 to remove the magnetic force between the electromagnetic sleeve 122 and the positioning rod 121. At this time, the electromagnetic sleeve 122 can be pushed to slide outside the positioning rod 12, which facilitates the adjustment of the position of the drill bit 126 in the horizontal direction. After the position of the drill bit 126 is adjusted, the circuit of the electromagnetic sleeve 122 can be connected, so that the electromagnetic sleeve 122 and the positioning rod 12 are fixed by magnetic attraction. Then, turn on the drive motor 124 to make the drill bit 126 rotate at high speed. At the same time, start the electric push rod 123 to extend it. The electric push rod 123 will drive the drive motor 124 and the drill bit 126 to move down, so that the bottom end of the drill bit 126 contacts the surface of the steel body of the power transmission tower and continues to extend into the interior of the steel body of the power transmission tower, thereby drilling holes in the steel body of the power transmission tower.

[0044] Both the drilling component 120 and the sliding component 130 are implemented using the technology described in the prior art, thus enabling multi-position drilling of steel.

[0045] In use, the steel material of the power transmission tower that needs to be drilled is placed on top of the drilling table 140, with the bottom ends of both ends of the steel material located on the inner wall of the U-frame 160. At this time, the double-headed motor 150 is controlled to work, and its output end will drive the two sets of lead screws 151 to rotate, pulling the driven sleeve 152 to slide linearly and approach each other on the outer wall of the lead screw 151. At this time, driven by the vertical plate 162, the two sets of U-frames 160 will move closer to each other, and the trapezoidal block 168 will move linearly within the notch 142 and will interact with the trapezoidal strip. The inclined surface of the bottom of the 170 contacts the trapezoidal bar 170, which exerts a downward squeezing force on the trapezoidal block 138, causing the trapezoidal block 138 and the base rod 166 at the top to drop together. At this time, the active bar 161 and the driven bar 163 below will drop synchronously. The driven bar 163 will contact the upper surface of the steel and cooperate with the two sets of U-frames 160 that are close to each other to complete the purpose of clamping the placed transmission tower steel. In this way, the drilling component above can be controlled to perform the drilling step.

[0046] When the dimensions and thickness of the steel material of the transmission tower to be drilled change, the trapezoidal strip 170 is loosened and removed manually using tools. The installation position of the trapezoidal strip 170 is then re-determined based on the length of the plate material to meet the purpose of clamping the steel material of the required dimensions.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
