Description

Technical Field

[0001] This invention relates to the field of engineering technology for water-drilling cutting on curved concrete structures in projects such as subway shield tunnel sections, mined tunnel concrete structures, irregularly shaped curved concrete buildings, precast concrete pipes and other municipal engineering concrete structures, specifically a fixing device for water-drilling cutting on curved concrete segments. Background Technology

[0002] In subway shield tunnel sections, mined tunnel concrete structures, irregularly shaped concrete curved surface buildings, and municipal engineering projects, water-jet cutting technology is widely used for hole opening and cutting operations in concrete structures. However, due to the curved surface characteristics of concrete structures, traditional cutting processes present many difficulties in fixing the water-jet drill, such as: it cannot be quickly and stably fixed to the curved concrete segment; the cut lines are not straight and aesthetically pleasing; and secondary manual processing is required later. Often, fixing bolts are used to directly fix the drill to the concrete segment, one bolt per hole, requiring multiple fixations during the cutting process, resulting in significant waste of manpower and resources, as well as time. Summary of the Invention

[0003] The purpose of this invention is to provide a fixing device for water-drill cutting on curved concrete pipe segments, so as to solve the problems mentioned in the background art, such as: cumbersome water-drill cutting and fixing: each cut requires re-drilling and fixing, consuming a lot of manpower and fixing bolts; poor cutting quality: the cutting lines are uneven, requiring secondary manual processing in the later stage, which increases construction time and cost; and material waste: the fixing bolts cannot be reused, causing material waste.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fixing device for water-drill cutting on curved concrete pipe segments, comprising a water-drill fixing base, wherein the water-drill fixing base is provided with a first base and a second base, and the first base and the second base are respectively provided with sliding tracks for sliding engagement of the water-drill fixing base, the water drill is installed on the water-drill fixing base, the water drill fixing base is provided with a mounting seat, the mounting seat is provided with a drive rod, the drive rod engages with the water drill housing, the two ends of the first base and the second base are respectively provided with fixing bolts, and the middle sides of the first base and the second base are respectively provided with adjustable support structures, the adjustable support structure including a mounting plate fixed on the first base or the second base, the mounting plate is provided with a threaded rod with thread engagement, and the inner end of the threaded rod is provided with a hinge seat that is hinged to the threaded rod.

[0005] Preferably, the first base and the second base are fixedly installed.

[0006] Preferably, the first base and the second base are connected by hinge bolts.

[0007] Preferably, the first base and the second base are respectively provided with vertical graduation lines.

[0008] Preferably, an angle scale is provided on the second base, which is circular with the hinge bolt.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] This invention achieves multi-hole cutting with a single fixing, reducing labor and material consumption, improving construction efficiency, controlling the cutting line shape, ensuring straight and beautiful cutting lines, and saving labor costs. It changes the original method of fixing one hole at a time to performing multi-hole construction with a single fixing, thus saving a certain amount of labor costs. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0016] Example 1

[0017] like Figure 1-2 As shown, this invention provides a fixing device for water-drill cutting on curved concrete pipe segments, including a water-drill fixing base. The water-drill fixing base is made of two steel plates, namely a first base 1 and a second base 2. The steel plates are cut to the required size, and a slide 4 is cut in the middle. The water-drill fixing base can slide along the slide 4. The slide 4 serves as a guide for the water-drill fixing base and the water drill 14, ensuring that the cutting line of the pipe segment is straight. The first base 1 and the second base 2 are vertically fixed. A φ2cm round hole is opened at each end of the first base 1 and the second base 2 for cooperating with the fixing bolt 7, i.e., the expansion bolt. The first base 1 and the second base 2 are fixed to the curved concrete structure 8 by the fixing bolt 7. The water drill 14 is mounted on the water drill mounting base. The water drill mounting base is provided with a mounting seat 9. The mounting seat 9 is provided with a drive rod 10. The drive rod 10 cooperates with the water drill housing. The axis of the drive rod 10 is parallel to the axis of the water drill bit. The water drill 14 is driven to move axially by the drive rod 10 to control the cutting depth of the water drill. The drive rod 10 can be set as a lead screw driven by a motor or as a hydraulic rod controlled by a hydraulic cylinder.

[0018] Adjustable support structures are respectively provided on both sides of the middle of the first base 1 and the second base 2. The adjustable support structure includes a mounting plate 11 fixed on the first base 1 or the second base 2. A threaded rod 12 with threaded engagement is provided on the mounting plate 11. A hinge seat 13 with hinge engagement is provided on the inner end of the threaded rod 12. An adjustable threaded rod 12 is provided in the middle of the mounting plate 11. The adjustment of the threaded rod 12 makes the hinge seat 13 fit with the concrete structure. The adjustable support structure is used to support the gap between the water drill fixing device and the curved concrete structure 8 and to adjust the drilling angle, so as to ensure that the first base 1 or the second base 2 fits tightly with the concrete structure and prevents the base from vibrating and displacing during drilling.

[0019] When fixing this device, it must be firmly secured to ensure the stability of the water drill during subsequent construction. The device should be fixed in a position parallel to the design lines to ensure that the cut lines are straight and aesthetically pleasing.

[0020] Example 2

[0021] like Figure 2-3 As shown in this embodiment, a fixing device for water-drill cutting on curved concrete pipe segments includes a water-drill fixing base. The water-drill fixing base is made of two steel plates, namely a first base 1 and a second base 2, and a hinge bolt 3. The steel plates are cut to the required size, and a slide rail 4 is cut in the middle. The water-drill fixing base can slide along the slide rail 4. The slide rail 4 serves as a guide for the water-drill fixing base and the water drill 14, ensuring that the cutting line of the pipe segment is straight. A straight scale line 5 is engraved on one side of the slide rail 4 to control the spacing of the water-drill holes and measure the cutting length. An angle scale 6 is set on one section of one of the steel plates. In this embodiment, the angle scale 6 is engraved on the second base 2. The first base 1 and the second base 2 are installed by the hinge bolt 3. Loosening the hinge bolt 3 allows the first base 1 and the second base 2 to rotate around the hinge bolt 3. Tightening the hinge bolt 3 fixes the installation angle of the first base 1 and the second base 2. The angle between the two tangents can be adjusted as needed to achieve accurate line shape. A φ2cm circular hole is drilled at each end of the first base 1 and the second base 2 for mating with the fixing bolt 7 (expansion screw). The first base 1 and the second base 2 are fixed to the curved concrete structure 8 by the fixing bolt 7. The water drill 14 is mounted on the water drill fixing seat. The water drill fixing seat is equipped with a mounting base 9, and the mounting base 9 is equipped with a drive rod 10. The drive rod 10 is mated with the water drill housing. The axis of the drive rod 10 is parallel to the axis of the water drill bit. The drive rod 10 drives the water drill 14 to move axially, controlling the cutting depth of the water drill. The drive rod 10 can be a lead screw driven by a motor or a hydraulic rod controlled by a hydraulic cylinder.

[0022] Adjustable support structures are respectively provided on both sides of the middle of the first base 1 and the second base 2. The adjustable support structure includes a mounting plate 11 fixed on the first base 1 or the second base 2. A threaded rod 12 with threaded engagement is provided on the mounting plate 11. A hinge seat 13 with hinge engagement is provided on the inner end of the threaded rod 12. An adjustable threaded rod 12 is provided in the middle of the mounting plate 11. The adjustment of the threaded rod 12 makes the hinge seat 13 fit with the concrete structure. The adjustable support structure is used to support the gap between the water drill fixing device and the curved concrete structure 8 and to adjust the drilling angle, so as to ensure that the first base 1 or the second base 2 fits tightly with the concrete structure and prevents the base from vibrating and displacing during drilling.

[0023] When fixing this device, it must be firmly secured to ensure the stability of the water drill during subsequent construction. The device should be fixed in a position parallel to the design lines to ensure that the cut lines are straight and aesthetically pleasing.

[0024] This invention achieves multi-hole cutting with a single fixing, reducing labor and material consumption, improving construction efficiency, controlling the cutting line shape, ensuring straight and beautiful cutting lines, and saving labor costs. It changes the original method of fixing one hole at a time to performing multi-hole construction with a single fixing, thus saving a certain amount of labor costs.
