Description

Technical Field

[0001] The utility model relates to an electric tool, in particular to a drilling tool for a cable bracket in a cable trench. Background Art

[0002] During infrastructure construction, such as rail transit and building wiring, cables need to be laid, and holes need to be drilled according to pre-set routes in order to further fix the cables. However, in many cases, the civil engineering foundation is constructed first, that is, the environment for laying the circuit is often prepared first, which brings great difficulties to the cable laying construction. For example, when drilling holes for laying cables in cable trenches, the space is small and it is inconvenient to drill holes in the trench wall. It is not only time-consuming and labor-intensive, but also difficult to control the space, which easily leads to unsatisfactory drilling results, leaving great safety hazards for the subsequent cable laying.

[0004] Furthermore, the fixed support frame is composed of a fixed frame carrying a drilling tool and a support frame supporting the entire drilling tool at a specified position in the cable trench. The support frame is a rectangular frame composed of two long rods and a plurality of connecting rods, wherein the two ends of the two long rods are set telescopic structures and are fixed with bolts through holes set on them. The fixed frame is a rectangular frame fixedly connected to the bottom of the support frame, and a connecting rod for installing a guide rod is provided on the rectangular frame. The connecting rod for installing the guide rod and the guide rod, and the connecting rod for installing the guide rod and the fixed frame are both detachably connected with bolts through sleeves with holes.

[0005] Furthermore, the mounting frame is composed of two rectangular frames fixedly connected by a connecting rod, and the two rectangular frames are provided with holes for the guide rod to pass through.

[0006] Furthermore, two drilling tools can be fixed on the mounting frame, and the two drilling tools can be fixed with bolts through the mounting plate by arranging holes on the mounting frame.

[0007] Furthermore, the joystick is axially connected to the mounting frame via a connecting plate.

[0008] Furthermore, there are two guide rods.

[0009] The beneficial effects of the utility model are: the drilling position can be adjusted up, down, left and right, adapted to trench wall operations, easy to operate, saving work hours, and being sturdy and durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Note: This figure is only for structural illustration and is not limited to proportions and dimensions. DETAILED DESCRIPTION

[0012] In order to enable those skilled in the art to understand and implement the present invention, the structure of the present invention is described in detail below with reference to the accompanying drawings.

[0013] A drilling tool for a cable bracket in a cable trench, comprising a fixed support frame 1, a joystick 2 and a drilling tool 3, wherein the fixed support frame 1 is used to fix the entire drilling tool at a specified position in the cable trench, the joystick 2 is connected to the fixed support frame 1 through a sleeve, and uses the sleeve as a fulcrum to perform a lever movement, so as to drive the drilling tool 3 to perform drilling operations and reset, the drilling tool 3 is axially connected to the joystick 2 through a mounting frame 4 fixedly connected thereto, the mounting frame 4 is connected thereto through a guide rod 5 provided on 1 of the fixed support frame and can reciprocate along the guide rod 5 under the control of the joystick 2.

[0014] The fixed support frame 1 is composed of a fixed frame 1-1 carrying the drilling tool 3 and a support frame 1-2 supporting the entire drilling tool at a specified position in the cable trench. The support frame 1-1 is a rectangular frame composed of two long rods and multiple connecting rods, wherein the two ends of the two long rods are set with telescopic structures and are fixed with bolts through holes set on them. The fixed frame 1-2 is a rectangular frame fixedly connected to the bottom of the support frame 1-1, and a connecting rod for installing a guide rod is set on the rectangular frame. The connecting rod for installing the guide rod and the guide rod, and the connecting rod for installing the guide rod and the fixed frame are all detachably connected with bolts through a sleeve with holes. This structure and connection method can conveniently adjust the position of the drilling tool up, down, left, and right according to actual requirements to meet the needs of actual working conditions.

[0015] The mounting frame 4 is composed of two rectangular frames connected by connecting rods. Holes for guide rods to pass through are provided on the two rectangular frames, so that the drilling tool can be fixed more firmly and prevented from being displaced due to vibration during the drilling process. Two drilling tools can be fixed on the mounting frame. By setting holes on the mounting frame and fixing the two with bolts through the mounting plate, the construction of another hole can be completed at one time by fixing the two drilling tools, saving work time. The joystick is axially connected to the mounting frame through the connecting plate to make it more stable. There are two guide rods. Because the mounting frame is connected to the joystick, the mounting frame has three points for fixing, so that the purpose of stability can be achieved with fewer links.

[0016] In actual construction, after marking the drilling position, you only need to adjust the up and down position of the mounting frame as needed to drill holes at the same height of the cable trench. For some positions, such as the starting position and the end position, it is not easy to drill holes at the predetermined position due to the limitation of the lateral position, so the mounting frame needs to be adjusted laterally. When adjusting up and down, you need to loosen the bolts on the sleeve of the connecting rod and the fixing frame at both ends of the guide rod, adjust the position, and then lock it; for lateral adjustment, you only need to adjust the position of the sleeve at both ends of the guide rod. After completing the hole-turning operation, you can also loosen the bolts that lock the drilling tool and remove it to avoid damage to it during transportation and handling.
