Description

Fixing device for roadway bottom height measuring device

Technical Field

The utility model relates to a tunnel measuring equipment technical field specifically is a fixing device that tunnel bedding height measurement used.

Background

In the scientific research and safety monitoring work in the field of coal mines, the roadway arranged in the coal rock mass is inevitably deformed in the process of excavation and propulsion near a mining working face, the influence of the displacement change of the roadway top and bottom plates on the disturbance of research engineering, the control of surrounding rock deformation and disaster early warning, the guarantee of safety production and the like are important, and the bedding height of the roadway needs to be measured. In addition, in order to install the coal mining support in the later stage of the common roadway, the machine roadway needs to be constructed with a bottom, the distance between the floor and the bottom of the monorail crane is not less than 3.5 meters, the width of the floor is 1 meter from the left side to the right side of the center line of the monorail crane, and the height of the bottom of the roadway needs to be measured before construction. At present, in order to obtain the height of the bed, a steel ruler is usually manually held to measure so as to obtain the height of the bed. However, the space of the underground roadway of the coal mine is narrow and small, the environment is severe, and the handheld steel ruler is inconvenient to use for measurement in field measurement, so that the measurement efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve lies in how to improve the measurement of efficiency of tunnel bedding height.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a fixing device that tunnel dinting bottom height measurement ware was used, includes bottom plate, fixed plate, fly leaf, gyro wheel, retaining member and mounting, bottom plate top one end is fixed the fixed plate, the other end are fixed with can the pivoted fly leaf, one side that fixed plate and fly leaf are relative all is fixed with can hang rolling gyro wheel on the single track, still be fixed with the retaining member that can dismantle between fixed plate and the fly leaf, the bottom plate bottom is fixed the mounting.

The roller is fixed on the monorail crane, the roadway dinting bottom height measurer is fixed on the fixing device through the fixing piece to perform height measurement operation, manual handheld steel ruler measurement operation is replaced, the fixing device is connected with the outside pull rope, the rear of the roadway repairing machine is pulled and can drive the fixing device to move on the monorail crane, and therefore the movement of the roadway dinting bottom height measurer is driven, and the measurement efficiency of the roadway dinting bottom height is improved.

Preferably, the fixing plate is fixed on the bottom plate by welding.

Preferably, the movable plate is rotatably fixed to the base plate by a hinge.

Preferably, the rollers are rotatably fixed to the fixed plate and the movable plate through a central shaft, respectively.

Preferably, the locking member is a locking bolt.

Preferably, the fixing member is a fixing nut.

Compared with the prior art, the beneficial effects of the utility model are that:

Detailed Description

In order to facilitate the understanding of the technical solutions of the present invention by those skilled in the art, the technical solutions of the present invention will now be further described with reference to the drawings attached to the specification.

In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, removable connections, or integral parts; the connection can be mechanical connection, electrical connection or communication; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

In this application, unless explicitly stated or limited otherwise, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1, the embodiment discloses a fixing device that tunnel dinting bottom height measurement ware was used, including bottom plate 1, fixed plate 2, fly leaf 3, hinge 4, gyro wheel 5, retaining member 6 and mounting 7, the vertical welded fastening in 1 top one end of bottom plate fixed plate 2, the other end is fixed with movable leaf 3 that can rotate through hinge 4,

fixed plate

2 and 3 top relative one side in fly leaf all are fixed with can hang 8 at the single track and roll gyro wheel 5, still be fixed with the retaining member 6 that can dismantle between fixed plate 2 and the

fly leaf

3, 1 bottom of bottom plate is fixed mounting 7 for fixed tunnel dinting bottom height measurement ware.

It can be on single track hangs 8 to be fixed with gyro wheel 5, fixes the tunnel dinting bottom height measurement ware through mounting 7 and carries out the height measurement operation on this fixing device, has replaced the manual handheld steel rule measurement operation, and is connected with this fixing device through outside stay cord, repaiies quick-witted rear traction and can drive this fixing device and hang 8 upper portions at the single track in the lane and remove, thereby drives the removal of tunnel dinting bottom height measurement ware, improves the measurement of tunnel dinting bottom height.
