The device mainly comprises a sleeve, a steel support frame and a platform plate. The sleeve pipe passes through support frame welded connection with the landing slab, the steel sheet at two steel sheet middle parts of support frame plays stabilizing effect in the welding, the sleeve pipe embolias the drill pipe one end that needs the deviational survey when using, adjust to suitable position, screw up the bolt through sleeve pipe top bolt hole, this connecting device is whole fixed with the drill pipe this moment, the landing slab middle part is equipped with long rectangle hole groove, it is fixed with landing slab and theodolite with the bolt, the sleeve pipe axis is parallel with the landing slab, can survey the reading behind the leveling theodolite, this connection fixing device can satisfy the various angle deviational survey needs of design tube hole, and is convenient and practical.

Description

Connecting and fixing device for drill pipe and theodolite during pipe hole inclination survey

Technical Field

The utility model belongs to the technical field of the deviational survey of tube hole among the tunnel construction, especially, relate to a drilling pipe and theodolite's be connected fixing device during tube hole deviational survey.

Background

Pipe hole inclinometry is an important process of tunnel freezing method construction, whether a drill pipe is in a designed position or not can be known through inclinometry data, but the problems of pipe hole inclinometry in the current tunnel are mainly as follows: the theodolite is directly erected on the drilling platform and cannot be drilled simultaneously, so that the construction progress is influenced; the space in the tunnel is narrow and small, and the erection of the theodolite is difficult. The device solves the two problems, is simple and practical and saves space.

SUMMERY OF THE UTILITY MODEL

The utility model aims at studying a drilling pipe and theodolite when pipe hole deviational survey be connected fixing device, provide a simple and practical, maneuverability is strong, long service life, the higher drilling pipe of precision and the theodolite between be connected fixing device.

In order to achieve the above purpose, the utility model adopts the following scheme:

a connection and fixation device for a drill pipe and a theodolite during pipe hole inclination measurement mainly comprises a sleeve, bolts, a steel support frame and a platform plate. The middle part of the platform plate is provided with a rectangular hole groove, and the sleeve pipe is connected with the platform plate through a steel support frame in a welding way.

The sleeve is a circular steel pipe with the length of 100mm and the diameter of 100mm, the top of the sleeve is provided with a bolt hole, and the bolt is screwed so as to fix the connection between the sleeve and the drill pipe; the steel support frame is formed by welding two strip-shaped steel plates at equal intervals and is used for connecting the sleeve and the platform plate; the platform board is 120mm steel sheet, and the middle part is equipped with 80mm 10mm rectangle hole groove for fixed theodolite.

The utility model has the advantages that: compared with the traditional theodolite support, the fixing device has the characteristics of strong adaptability, easiness in operation, space saving and the like, is suitable for narrow and complex environments of work places such as tunnels, improves the inclinometry efficiency, and contributes to shortening the construction period.

Illustration of the drawings: 1. the steel plate drilling machine comprises a sleeve, 2 bolts, 3 steel support frames, 4 platform plates, 5 bolt holes, 6 rectangular hole grooves, 7 steel sheets, 8 theodolite and 9 drill pipes.

Detailed Description

The utility model provides a drilling pipe is connected fixing device with the theodolite when being used for deviational survey, for making the utility model discloses the model of establishing, the technical scheme of realization, the purpose effect characteristic of reaching are clear more clear and definite, and it is right to combine the drawing below the utility model discloses do further explanation.

As shown in figure 1, the device for connecting and fixing the drill pipe and the theodolite during inclination measurement comprises a sleeve 1 with the diameter of 100mm, bolts 2, a steel support frame 3 and a platform plate 4. The top of the sleeve pipe 1 with the diameter of 100mm is provided with bolt holes 5, the steel support frame 3 is formed by welding two strip-shaped steel plates at equal intervals, and the middle part of the platform plate 4 is provided with a long rectangular hole groove 6.

As shown in fig. 2, in order to finely adjust and fix the theodolite horizontally, a long rectangular hole groove 6 is formed in the middle of the platform plate 4, and a steel sheet 7 used for stabilization is arranged between the supporting frames and is welded with the steel frame.

As shown in fig. 3, the sleeve 1 is welded to the platform plate 4 through the steel support frame 3, and the top of the sleeve is provided with a bolt hole 5.

The device embolias the drill pipe 9 with sleeve pipe 1 when deviational survey, screws up bolt 2 through bolt hole 5 fixedly, produces pressure between sleeve pipe 1 and the drill pipe 9 and makes it compress tightly each other, and steel support frame 3 plays the contact effect, because the axis of sleeve pipe 1 keeps parallel with landing slab 4, so directly put up theodolite 8 on landing slab 4, fixes theodolite 8 through rectangular hole groove 6, can read after the leveling.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, the scope of the present invention is not limited thereto. On the basis of the technical scheme of the utility model, various modifications, equivalent replacements, deformation, improvements and the like which can be made without creative work are still within the protection scope of the utility model.
