Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, and more specifically, to a cable trench drilling device. Background Art

[0002] The cable trench is a channel for protecting cables. When placing cables, it is necessary to keep the cables at a certain distance from the ground to protect the cables. This problem can be solved by installing cable brackets on the cable trench. The usual practice is to drill holes on one side of the cable trench, install expansion bolts to fix the cable brackets, and finally place the cables. When drilling holes, first lay out the lines to determine the drilling positions, and then workers use electric drills to manually drill holes in a small space. Due to the long distance and the large number of holes, workers cannot operate for a long time, and cannot ensure the consistency of the drilling direction, which causes the problem of cable bracket installation offset. Multiple workers are also used to drill holes at the same time, but the depth of the holes and the consistency of the drilling direction cannot be ensured. Utility Model Content

[0022] The utility model is further configured that the angle steel bracket 2 is divided into an upper bracket and a lower bracket, and two electric drills 1 are provided and fixedly mounted on the upper bracket and the lower bracket respectively. The angle steel bracket 2 is an upper bracket and a lower bracket composed of an angle steel and a screw. By adjusting the height of the angle steel bracket 2, the upper and lower distances between the drill holes can be adjusted, so that the upper and lower spacings can be kept consistent, thereby making the cable bracket installation more stable.

[0023] The utility model is further configured that the sliding drag rod 3 is connected to the upper bracket by welding.

[0024] The utility model is further configured that the pulley 4 has a diameter of 7CM and is made of rubber.

[0025] The utility model is further configured such that the movable frame 6 is a rectangular parallelepiped structure welded from different channel steels and angle steels, an extension portion is provided at the top of the movable frame 6 extending 5 cm toward the drill bit, and another group of pulleys 4 is cooperatively connected with the extension portion.

[0028] The utility model is further configured that a light strip 13 and a switch button 11 are provided on the movable frame.

[0029] During use: When drilling and installing the cable bracket in the tunnel cable trench, first hang the drilling device in the cable trench so that the upper pulley 4 of the movable frame 6 is placed on the upper edge of the cable trench. Since the light in the tunnel cable trench is dim, it is not easy to determine the drilling position. The device is installed with a lighting strip 13. After turning on the lighting strip 13, move the device back and forth. After determining that the drill bit is placed at the drilling position, turn on the electric drill. A worker holds the operating lever and pushes it to one end. The short end of the operating lever will touch the pad 9. As the force in the worker's hand continues to increase, the pad 9 is subjected to the force, causing the angle steel bracket 2 to slowly move forward, so that the electric drill acts on the trench wall of the cable trench to drill holes. The drilling depth can be determined by observing the ruler 12 next to it. When the drilling is completed After completion, the worker removes the force on the control rod 8 and swings the control rod 8 to its original position. At this time, the tensioned spring 10 will rebound and return the angle steel bracket 2 to its original position. After completion, the mobile frame 6 is slid to the next punching point. The whole device is very convenient to operate and can be easily completed by one person. The operation is labor-saving, simple, fast, economical and practical. It can not only reduce the construction difficulties caused by the limited space of the cable trench, but also avoid the deviation of the hole caused by uneven force of manual punching, making it difficult to insert the expansion bolt, causing the cable bracket to be unstable, etc. Moreover, after use, the device can be directly slid to the next construction site, which can be reused many times without generating any extra waste, can greatly improve labor productivity, and ensure the consistency of punching height.

[0030] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
