Description

Technical Field

[0001] The utility model relates to the technical field of railway construction, in particular to a mobile wire trough opening machine. Background Art

[0002] Cable trenches are underground pipelines used for laying and replacing power or telecommunication cable facilities. They are also the enclosure structures of the laid cable facilities. They have rectangular, circular, arched and other pipeline structures. During the construction process, according to the power demand, some cables need to pass through the cable trench wall for communication layout. In the early days, drilling holes in the cable trench wall was mostly done by manual drilling. However, manual drilling methods have problems such as drill bit jumping or swinging during drilling, difficulty in ensuring hole consistency, difficulty in drilling inclined holes, high work intensity, and high safety risks. In order to solve the problems caused by manual drilling, Chinese patent CN219061514U discloses a cable trench punching device, including a positioning device, a feed drive device, a drilling device and a fixing device. The positioning device includes a positioning frame, and the front and rear ends of one side of the positioning frame are respectively screwed with adjusting screws, and the adjusting screw is located at one end inside the positioning frame and is installed with a top plate, and the top plate is abutted against the cable trench wall; the feed drive device is installed on the top of the positioning frame; the drilling device includes a guide frame, a connecting slider, a motor, and a drill bit. The right end of the guide frame is connected to the positioning frame, and the angle between the guide frame and the positioning frame is adjustable. The connecting slider is installed on the guide frame, the output end of the feed drive device is connected to the connecting slider, the motor is installed at the bottom end of the connecting slider, and the drill bit is connected to the output shaft of the motor; the fixing device is fixedly connected to the left end of the guide frame.

[0003] In the above-mentioned prior art, when drilling holes on the cable trench wall, firstly, the positioning frame is set on the upper end of the cable trench wall so that the upper end of the cable trench wall is clamped in the positioning frame, and then the adjusting screw is screwed to adjust the length of the adjusting screw extending out of the inner wall of the positioning frame so that the top plate abuts against the inner wall of the cable trench, thereby fixing the positioning frame on the cable trench wall, and then adjusting the angle between the guide frame and the positioning frame, and supporting the other end of the guide frame through the fixing device and fixing its position, starting the motor to drive the drill bit to drill holes on the cable trench wall, and at the same time starting the feed drive device to drive the connecting slider to move, thereby driving the drill bit to feed in the direction of the cable trench wall while drilling holes, thereby completing the drilling work. The angle between the guide frame and the positioning frame can be adjusted, so that the opening of inclined holes on the end wall of the cable trench can be satisfied.

[0004] Although the above-mentioned prior art has replaced the work of manual drilling, the following problems still exist in the actual construction process:

[0005] 1) In the above-mentioned prior art, when the punching device is fixed by the positioning frame and the adjusting screw, it is all fixed manually, and each time a punching position is moved, the adjusting screw and the positioning frame need to be released and moved and fixed again, which is inconvenient to operate and time-consuming and labor-intensive;

[0006] 2) The punching device in the prior art needs to be moved along the cable trench by hand during the movement of the punching gap, which is inconvenient to operate. Especially when walking in a tunnel, safety accidents are prone to occur when the operator walks along the cable trench in the dark, posing a great safety hazard. Utility Model Content

[0053] Based on any of the above embodiments, the drilling drive cylinder 41 is a gas-liquid linkage cylinder.

[0054] In this embodiment, the cable trench wall is usually cast by concrete, and steel bars are tied inside. When the drill bit 45 touches the steel bar position during the drilling process, the drilling drive cylinder 41 is pressurized to drill through the steel bar. At the moment of drilling through the steel bar, the resistance suddenly decreases, causing an instantaneous impact between the drill bit 45 and the cable trench wall, which can easily cause the channel to crack or tilt. The setting of the gas-liquid linkage cylinder can achieve buffering through hydraulic compensation at the moment the drill bit 45 drills through the steel bar, avoiding the generation of instantaneous impact force, thereby better completing the drilling operation.
