Technical Field

[0001] This utility model relates to the field of power transmission line tower forming and processing technology, specifically to a drilling device for power transmission line tower forming and processing. Background Technology

[0002] However, existing drilling equipment still has problems when processing transmission line towers, such as inconvenience in moving the drill holes up and down, inability to determine the drilling spacing, and lack of drilling cooling function.

[0003] In the prior art, Chinese patent document CN209754533U was proposed to solve the above-mentioned technical problems. The technical solution disclosed in this patent document is as follows: A multifunctional drilling device for processing high-voltage transmission line towers, including a stop pipe, a support column, a selector switch, a movable base, and universal wheels with brake pads. The arrangement of the spacing line, cuboid support column, sliding pipe, stop ring, hand handle, and rectangular movable pipe in this utility model is conducive to sliding adjustment of the drilling spacing, and can also determine the size of the drilling spacing to ensure the accuracy of the drilling position; the arrangement of connecting pipe head, spray pipe, adjusting seat, connecting liner, wing screw, and cooling nozzle is conducive to connecting an external cooling water tap for drilling cooling.

[0004] However, there are still cases where the iron tower is simply placed on the device, which leads to the problem that the iron tower is prone to displacement during drilling. Utility Model Content

[0005] The purpose of this utility model is to provide a drilling device for forming and processing transmission line towers, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A drilling device for forming and processing transmission line towers includes a movable base, a limit component is provided on the surface of the movable base, an adjustment mechanism is provided on the top surface of the movable base, and a drilling mechanism is provided on the surface of the adjustment mechanism.

[0008] The limiting assembly includes a downward limiting unit and a lateral limiting unit. The lateral limiting unit is disposed on the surface of the downward limiting unit, and the downward limiting unit includes a first screw, a lifting block, a limiting plate, and a stop plate. The lateral limiting unit includes a second screw and a secondary limiting plate.

[0009] A further improvement of this utility model is that the movable base includes a base main board, shock-absorbing wheels are fixedly installed at the four ends of the bottom surface of the base main board, and a positioning rod is fixedly installed on the bottom surface of the base main board. The positioning rod includes a threaded outer cylinder, a threaded inner cylinder, and a positioning plate. By directly replacing the large movable base and anti-slip rubber rollers with a short base main board, it is possible to support the entire movable device while moving it to the iron tower for processing, without having to spend time and effort to move the iron tower onto the device.

[0010] A further improvement of this utility model is that: the surface of the first screw is slidably connected to the inner surface of the base main board; the lifting block is threadedly connected to the first screw; the limiting plate and the lifting block are connected by a support rod; and the surface of the abutment plate is fixedly connected to the surface of the lifting block. By setting a downward limiting unit, when the device moves to the iron tower, the limiting plate can be rotated on the lifting block and contact the abutment plate, and then the first screw can be rotated to make the lifting block drive the limiting plate to move down and contact the iron tower to press and hold it, thereby improving stability.

[0011] A further improvement of this utility model is that: the second screw is inserted and installed on the limiting plate and its surface is slidably connected to the inner surface of the limiting plate; the secondary limiting plate and the second screw are threadedly connected and their surfaces are slidably connected to the inner surface of the limiting plate; by setting a transverse limiting unit, after the iron tower is pressed down and stabilized, the second screw can be rotated to make the secondary limiting plate move inward for hooking, thereby cooperating with the moving seat and the pressing limiting unit to achieve triangular clamping and improve the stability of drilling.

[0012] A further improvement of this utility model is that the adjustment mechanism includes a lifting frame fixedly installed on the top surface of the base main board, a first electric push rod is fixedly installed on the surface of the base main board and its output rod top surface is fixedly connected to the inner frame support block of the lifting frame, and a second electric push rod is fixedly installed on the inner frame surface of the lifting frame. The adjustment by using electric push rods is less affected by temperature than that by using motors.

[0013] A further improvement of this utility model is that the drilling mechanism includes an electric lifting rod that is slidably installed on the surface of the inner frame slide rod of the lifting frame. A drill is fixedly installed on the bottom surface of the output rod support plate of the electric lifting rod. A cooling nozzle is inserted and installed on the surface of the output rod support plate of the electric lifting rod. By setting the electric lifting rod, the drilling depth can be finely adjusted during drilling.

[0014] A further improvement of this utility model is that: the lifting block passes through the first electric push rod and overlaps with the outer frame of the lifting frame; one end of the output rod of the second electric push rod is fixedly connected to the moving seat of the electric lifting rod; the overlap between the lifting block and the lifting frame can play a limiting role and prevent the screw from rotating, which would cause the lifting block to rotate as well.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] This utility model provides a drilling device for forming and processing transmission line towers. By directly replacing the large movable base and anti-slip rubber roller with a short base main board, it can support the entire movable device and move it to the tower for processing without having to spend time and effort to move the tower onto the device.

[0017] This utility model provides a drilling device for forming and processing transmission line towers. By setting a downward limiting unit, when the device moves to the tower, the limiting plate on the lifting block can be rotated and contact the stop plate. Then, the first screw is rotated so that the lifting block drives the limiting plate to move down and contact the tower to press and hold it, thereby improving stability.

[0018] This utility model provides a drilling device for forming and processing transmission line towers. By setting a lateral limiting unit, after the tower is pressed down and stabilized, the second screw is rotated to make the secondary limiting plate move inward for hooking. This can be combined with the moving seat and the pressing limiting unit to achieve triangular clamping and improve the stability of drilling. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1

[0027] like Figure 1-5 As shown, this utility model provides a drilling device for forming and processing transmission line towers, including a movable base 1. The movable base 1 includes a base main board 11. Shock-absorbing wheels 12 are fixedly installed at four ends of the bottom surface of the base main board 11. A positioning rod 13 is fixedly installed on the bottom surface of the base main board 11, and the positioning rod 13 includes a threaded outer cylinder, a threaded inner cylinder, and a positioning plate. A limit component 2 is provided on the surface of the movable base 1, and an adjustment mechanism 3 is provided on the top surface of the movable base 1. A drilling mechanism 4 is provided on the surface of the adjustment mechanism 3. The limit component 2 includes a lower pressure limit. The device consists of a positioning unit and a lateral limiting unit. The lateral limiting unit is located on the surface of the downward limiting unit and includes a first screw 21, a lifting block 22, a limiting plate 23, and a stop plate 24. The lateral limiting unit includes a second screw 25 and a secondary limiting plate 26. By setting the downward limiting unit, when the device moves to the tower, the limiting plate 23 can be rotated on the lifting block 22 and contact the stop plate 24. Then, the first screw 21 can be rotated so that the lifting block 22 drives the limiting plate 23 to move down and contact the tower to press and hold it, thereby improving stability.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the surface of the first screw 21 is slidably connected to the inner surface of the base main board 11, the lifting block 22 is threadedly connected to the first screw 21, the limiting plate 23 and the lifting block 22 are connected by a support rod, the surface of the abutment plate 24 is fixedly connected to the surface of the lifting block 22, the second screw 25 is inserted and installed on the limiting plate 23 and its surface is slidably connected to the inner surface of the limiting plate 23, the secondary limiting plate 26 is threadedly connected to the second screw 25 and its surface is slidably connected to the inner surface of the limiting plate 23. By setting a transverse limiting unit, after the iron tower is pressed down and stabilized, the second screw 25 can be rotated to make the secondary limiting plate 26 move inward for hooking, thereby cooperating with the moving seat 1 and the pressing limiting unit to achieve triangular clamping and improve the stability of drilling.

[0030] Example 3

[0031] like Figure 1-5As shown, based on embodiments 1-2, this utility model provides a technical solution: Preferably, the adjustment mechanism 3 includes a lifting frame 31 fixedly installed on the top surface of the base main board 11, a first electric push rod 32 fixedly installed on the surface of the base main board 11 and its output rod top surface fixedly connected to the inner frame support block of the lifting frame 31, a second electric push rod 33 fixedly installed on the inner frame surface of the lifting frame 31, and a drilling mechanism 4 including an electric lifting rod 41 slidably installed on the inner frame slide rod surface of the lifting frame 31, a drill 42 fixedly installed on the bottom surface of the output rod support plate of the electric lifting rod 41, a cooling nozzle 43 inserted into the surface of the output rod support plate of the electric lifting rod 41, a lifting block 22 passing through the first electric push rod 32 and overlapping with the outer frame of the lifting frame 31, and one end of the output rod of the second electric push rod 33 fixedly connected to the movable seat of the electric lifting rod 41. The overlap between the lifting block 22 and the lifting frame 31 can play a limiting role and prevent the screw rotation from causing the lifting block 22 to also rotate.

[0032] The working principle of the drilling device used for forming and processing transmission line towers will be explained in detail below.

[0033] like Figure 1-5 As shown, when the drilling device is in use, the limiting plate 23 is rotated on the lifting block 22 to make it abut against the stop plate 24. The entire device is moved to the iron tower by the shock-absorbing wheel 12, and the base main plate 11 is attached to the iron tower or penetrates to its bottom. The threaded inner cylinder is rotated on the outer cylinder of the screw groove to make the positioning plate move down to contact the ground for position fixation. The first screw 21 is rotated to make the limiting plate 23 move down to press down and limit the iron tower. Then the second screw 25 is rotated to make the secondary limiting plate 26 move to hook-type limit the iron tower.

[0034] The height and lateral position of the drill 42 can then be adjusted using two sets of electric actuators. Finally, the electric lifting rod 41 and the drill 42 are started to perform drilling. At the same time, a water pump can be connected to the cooling nozzle 43 to spray water to cool the drilling area.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
