Abstract
The utility model relates to the technical field of tunnel detection, in particular to a concrete core drilling machine vertical frame for detecting the concrete strength of a tunnel entity in railway engineering; the method comprises the following steps: lengthening the round steel bar and lengthening the hollow sleeve; the lengthened circular steel bar is fixedly connected with the vertical frame; sleeving the lengthened hollow sleeve into the lengthened circular steel bar and fixedly connecting the lengthened hollow sleeve with the vertical frame; the lengthened hollow sleeve is provided with a toothed sliding rail matched with the vertical frame; the beneficial effects of the utility model reside in that: the utility model discloses a to bore the stand of core machine stand upper end extension range integral type among the existing equipment, solved among the existing equipment concrete design thickness all be greater than the core machine stand range and adopt the technical problem of connecting the drill bit many times, to boring the loaded down with trivial details of installing the machine about after the core concrete core appearance is redrilled because of fracture or double-layered stopper disintegrating slag and having obviously improved, labour saving and time saving obtains the fine recognition of staff in the real work.
Description
Technical Field
The utility model relates to a tunnel detects technical field, concretely relates to railway engineering is used for concrete core drilling machine to erect frame that tunnel entity concrete intensity detected.
Background
At the present stage, when the strength of inverted arch concrete of a railway tunnel entity is detected, a rack is installed on a stand column of a machine frame, adjustable screws are installed at four corners of a base, and M16 expansion bolts are pre-embedded on the corresponding ground to fix a vertical frame in a traditional concrete core drilling machine; the core drilling machine is sleeved on the vertical frame, a gear pair is formed by a gear inside the core drilling machine and a toothed sliding rail on the vertical frame, and the feeding handle is rotated to enable the core drilling machine to move up and down along the upright post; the length of the device is as follows: 46cm, diameter: 7 sections of 10cm drill bits, wherein the upper part of each section of drill bit is turned with an inner wire, the lower part of each section of drill bit is turned with an outer wire, so that each section of drill bit can be tightly connected, and the total drilling depth is as follows: 322cm, a core drilling method is to drill a core sample from the surface of concrete to the bottom of a structural object to be detected by using a core drilling machine, and the concrete of the structural object in the tunnel is thicker due to the complex geological structure, different grades of mountain surrounding rocks and the complex size of the railway tunnel engineering. The common core drilling machine has shorter vertical frame, smaller measuring range, fussy working procedure and complex operation when drilling thicker concrete;
the drawbacks of this device are two-fold:
a. when the designed thickness of the concrete is larger than the range of a vertical frame of the core drilling machine and the drill hole is deeper, a drill bit needs to be frequently connected for core drilling;
b. After the core drilling is finished, the vertical frame of the core drilling machine is perpendicular to the drilling direction, so that an operator needs to take the core drilling machine off the vertical frame when the hole is explored for sampling, and the complex operation and the low efficiency are realized.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a vertical frame of a concrete core drilling machine aiming at the defects of the prior equipment; which comprises the following steps: the lengthened round steel bar (1) and the lengthened hollow sleeve (2); the lengthened circular steel bar (1) is fixedly connected with the vertical frame (5); the lengthened hollow sleeve (2) is sleeved into the lengthened circular steel bar (1) and is fixedly connected with the vertical frame (5);
a toothed sliding rail (7) matched with the vertical frame (5) is arranged on the lengthened hollow sleeve (2);
the length of the lengthened circular steel bar (1) is 90cm, and the diameter of the lengthened circular steel bar is 5 cm;
the lengthened hollow sleeve (2) is a square steel pipe with the length of 50cm and the side length of 5 cm.
The utility model discloses a use like this:
the base (6) is fixed on the surface of concrete through pre-embedded expansion screws, and the motor (3) with the drill bit (4) arranged thereon is arranged on the vertical frame (5), so that the power-on drilling work can be carried out; if a fault occurs when sampling or drilling is required; the motor (3) can be lifted to the extended part of the lengthened circular steel bar (1), the drill bit is deviated from the sampling hole by rotating the motor (3), so that sampling or fault removal can be realized, and then the motor (3) is rotated again to enable the drill bit to align to the sampling hole to continue to perform repeated drilling work.
The beneficial effects of the utility model reside in that:
the utility model discloses a to bore the stand of core machine stand upper end extension range integral type among the existing equipment, solved among the existing equipment concrete design thickness all be greater than the core machine stand range and adopt the technical problem of connecting the drill bit many times, to boring the loaded down with trivial details of installing the machine about after the core concrete core appearance is redrilled because of fracture or double-layered stopper disintegrating slag and having obviously improved, labour saving and time saving obtains the fine recognition of staff in the real work.
