Description

Technical Field

[0001] The invention relates to the technical field of water-grinding drills, in particular to a supporting device of a water-grinding drill for excavating a deep foundation pit in sandstone geology. Background Art

[0002] In the excavation of deep foundation pits in sandstone geology, a water-grinding drill is used to perform pre-drilling treatment, dividing the construction area into several small areas, and then blasting and other methods are used to remove the rocks in the small areas.

[0003] During the use of the water drill, a scaffold is built in the construction area in advance, and the upper end of the column that enables the water drill to move up and down is against the scaffold, and the lower end is against the construction ground. When changing the work area, it is necessary to move the water drill and its lifting structure manually, which is quite physically demanding. At the same time, the power supply cable of the water drill is generally laid directly on the scaffold, which has the risk of the cable falling to the construction ground, and the support strength of the scaffold is ensured. The scaffold is built relatively densely, and the cable management is relatively inconvenient. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a support device for sandstone geological deep foundation pit excavation using a water-grinding drill, comprising two channel steels arranged side by side, a suspension rod is arranged above the channel steel, and a cable is folded and suspended on the suspension rod. In the actual construction process, the power supply wiring of the equipment is relatively random, and the safety of electricity use cannot be guaranteed. The arrangement of the cable improves the safety of electricity use.

[0005] Two second rotating shafts are arranged between the two channel steels, and rollers are arranged at the ends of the second rotating shafts, and the rollers are rollingly fitted on the inner side of the channel steels. An axial slider is axially slidably fitted on the two second rotating shafts together, and a column is arranged below the axial slider, and a bidirectional screw is threadedly connected to the upper end of the column, and the upper end of the bidirectional screw is threadedly connected to the axial slider. In the above operation, the column moves in the direction of the length of the channel steel, the axial direction of the second rotating shaft, and the vertical direction. At the same time, by rotating the bidirectional screw, the column is lowered, and the lower end of the column can be further pressed to fit closely with the construction surface to achieve the fixation of the column. When the column rises, the bidirectional screw can suspend the column again, and at this time, the column can be directly pushed to change its position, which reduces the labor intensity compared with the traditional method of manual lifting.

[0006] A lifting platform is vertically slidably arranged on the column, a water-milling drill is mounted on one side of the lifting platform, a hanging hole is arranged on the upper side wall of the lifting platform, an inclined block is symmetrically arranged on the inner side of the upper part of the column, a hanging rod is fixedly connected to the inclined surface of the inclined block, and the hanging rod extends out of the column, a spring is arranged between the two inclined blocks, a U-shaped buckling block is arranged on one side of the inclined block, the inner side of the buckling block is an inclined surface, and cooperates with the inclined surface of the inclined block, and when the buckling block moves toward the inclined block, the two inclined blocks are pressed close to each other. That is, when the lifting platform rises, the hanging hole on the lifting platform cooperates with the hanging rod to realize the position limitation of the lifting platform, and in the process of changing the position of the column, the tool at the lower end of the water-milling drill rubs against the ground, affecting the change of the position of the column, and pressing the buckling block can make the hanging rod retract into the inside of the column, detach from the hanging hole, and then release the lifting platform.

[0007] Preferably, the upper end of the channel steel is fixedly connected with an arc-shaped cross beam at equal distances, the end of the suspension rod is fixedly connected to the cross beam, and the lower end of the channel steel is fixedly connected with a plurality of support columns. The arc-shaped cross beam will not block the bidirectional screw.

[0008] Preferably, the middle portion of the bidirectional screw is fixedly connected to the second rotating handle, and the bidirectional screw can be rotated conveniently and labor-savingly through the second rotating shaft.

[0009] Preferably, a groove is provided on one side of the column, a rack is fixedly connected to the inner wall of the groove, a gear is provided inside the lifting platform, and the gear and the rack are meshed. The lifting platform is lifted and lowered by adopting the gear rack transmission mode. Since this mode has no self-locking effect, the above-mentioned structures such as hanging rods and buckling blocks are provided.

[0010] Preferably, the middle of the gear is fixedly connected to a first rotating shaft, the first rotating shaft extends out of the lifting platform, and the end is fixedly connected to a first rotating handle. By rotating the first rotating handle, the gear is rotated through the first rotating shaft, thereby realizing the lifting of the lifting platform.

[0011] Preferably, a bottom plate is fixedly connected to the bottom of the column. The bottom plate is provided to increase the contact area.

[0012] Preferably, the suspension rod is provided with a plurality of hanging rings, through which the cables pass. The hanging rings are used to avoid direct friction between the cables and the suspension rod, and the cables are fixedly connected to a hanging ring at a fixed length.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. It is equipped with hanging rods, hanging rings, etc., and the cables are stored and folded on the hanging rings to ensure the safety of electricity use and convenience of use.

[0015] 2. A second rotating shaft, roller, axial slider, bidirectional screw, etc. are provided to realize displacement of the column in three directions. Therefore, when the operating area of ​​the water drill is changed, the position of the water drill can be easily changed with the help of the above structure, thereby reducing labor intensity.

[0016] 3. By setting hanging rods, hanging holes, inclined blocks and pressing blocks, the lifting platform can be fixed on the column. The tool no longer contacts the ground, which is conducive to changing the position of the column. BRIEF DESCRIPTION OF THE DRAWINGS

That is, the equal long sides of the cable 6 are fixedly connected with a hanging ring 20, and this mode avoids the friction between the suspension rod 2 and the cable 6.

[0026] Two second rotating shafts 16 are arranged between the two channel steels 4, and rollers 17 are arranged at the ends of the second rotating shafts 16.
