Description

Technical Field

[0001] The utility model belongs to the technical field of drilling tools, in particular to a street lamp wire trough combined drill. Background Art

[0002] During streetlight installation, cable troughs are typically installed on the poles to ensure cable life, secure a fixed installation location, and avoid damage when drilling holes. These troughs are typically made of aluminum alloy and secured to the poles with screws. Therefore, prior to assembly, several screw holes must be drilled into the troughs to ensure stable installation. Currently, drilling is primarily done using benchtop drilling machines, which can only drill one screw hole at a time, resulting in low efficiency. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, the utility model provides a street light wire trough combined drill with high drilling efficiency.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0012] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0013] like Figures 1 to 3 As shown, a street light cable trough combination drill comprises: a mounting plate 1, the bottom of which is provided with multiple sets of drilling assemblies 2 along the length direction, and the distance between adjacent drilling assemblies 2 is adjustable. Each drilling assembly 2 is provided with a locking screw 5 for fixing its position on the mounting plate 1. Each drilling assembly 2 is provided with a worm gear 21 and a worm 22 that mesh with each other. The mounting plate 1 is provided with a drive rod 3 that coaxially passes through all worm gears 22. One end of the drive rod 3 is provided with a motor 31 to simultaneously drive all worm gears 22 to rotate, thereby driving the corresponding worm gears 21 to rotate. Because the worm gears 22 are all provided on the same drive rod 3, all worm gears 22 are coaxial, and therefore all worm gears 21 are also in a mutually parallel state. The worm gears 21 are all located on the same side of the worm gear 22, and a drill bit 4 is connected to the bottom of each worm gear 21.

[0014] Usage method 1: During drilling, the wire trough is arranged parallel to the bottom of the mounting plate 1, and the distance between the drilling components 2 is adjusted to be consistent with the predetermined screw hole spacing, and then the motor 31 is started and the drill is moved downward to simultaneously process multiple screw holes; Usage method 2: Multiple wire troughs are arranged vertically below the mounting plate 1, and the ends of the wire troughs are aligned so that adjacent wire troughs contact each other, and the drilling components 2 are adjusted so that the distance between adjacent drilling components 2 is the same and the spacing distance is consistent with the width of the wire trough, and then the motor 31 is started and the drill is moved downward to simultaneously drill multiple wire troughs. Both of the above two usage methods can drill multiple screw holes at a single time, which can effectively improve the drilling efficiency.

[0015] Preferably, the mounting plate 1 is arranged at the lower section of a movable rod of a telescopic device, and the telescopic device is arranged vertically. The telescopic device is a linear motor, a cylinder, a hydraulic cylinder or a reciprocating linear moving mechanism using a gear to drive a rack.

[0016] Preferably, Figures 1 to 3 As shown, the drilling assembly 2 includes a detachable rectangular housing 23, and the worm wheel 21 and the worm 22 are both arranged in the rectangular housing 23 to activate the protection of the transmission structure and safety protection.

[0017] Preferably, Figures 1 to 3As shown, a slide groove 11 is provided at the bottom of the mounting plate 1 along the length direction, and a slider 231 is provided at the top of the rectangular shell 23. The slider 231 is slidably arranged in the slide groove 11 to realize a sliding connection between the drilling assembly 2 and the mounting plate 1. The cross-sections of the slider 231 and the slide groove 11 are both T-shaped structures.

[0018] As a preferred embodiment of the present application, Figures 1 to 3 As shown, there are three groups of drilling assemblies 2, and a screw 6 parallel to the drive rod 3 is provided at the bottom of the mounting plate 1. One group of drilling assemblies 2 is provided at the light rod part in the middle of the screw 6, and its position along the axial direction of the screw 6 remains fixed. The other two groups of drilling assemblies 2 are respectively provided at both ends of the screw 6, and the drilling assemblies 2 at both ends are at the same distance from the middle drilling assembly 2, and the threads at both ends of the screw 6 are rotated in opposite directions. When adjusting the distance between the drilling assemblies 2, it is only necessary to rotate the screw 6. When rotating the screw 6, the position of the drilling assembly 2 in the middle position will remain fixed, and the drilling assemblies 2 at both ends will move toward the middle or both ends of the screw 6 at the same time to quickly adjust the spacing between the drilling assemblies 2, and it can also ensure that the spacing between adjacent drilling assemblies 2 is the same; more specifically, in this embodiment, the screw 6 passes through the slider 231.

[0019] Preferably, a handle is provided at one end of the screw rod 6 for manually adjusting the screw rod 6 .

[0020] The above description is only a preferred embodiment of the present invention and does not represent the only embodiment or limit the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
