DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] See also Figure 1-2 The utility model provides a technical solution: a temporary support for geological drilling in water conservancy projects, comprising two columns 1, the two columns 1 are arranged at a relative interval and a fixing plate 2 is detachably installed at the bottom, specifically: a U-shaped opening is arranged on the inner side of the fixing plate 2, and the front and rear of the U-shaped opening are connected to the column 1 through a through bolt and nut assembly, which is convenient for disassembly and installation and transportation, and a threaded limiting device 3 is passed through the fixing plate 2, and mounting grooves 4 are vertically arranged on the opposite surfaces of the two columns 1, an optical axis 5 is vertically fixed in the left mounting groove 4, and an optical axis 5 is vertically fixed in the right mounting groove 4 is vertically installed with a lead screw pair 6 rotating through the bearing, a low-speed forward and reverse motor 7 connected to the top of the lead screw of the lead screw pair 6 through a coupling is installed on the top of the right column 1, a moving block 8 is slidably sleeved on the outer wall of the optical axis 5, a connecting block 9 is fixed on the outer side of the threaded block of the lead screw pair 6, and a support plate 10 with through holes on the surface is detachably installed horizontally between the moving block 8 and the connecting block 9. Specifically, a support plate 10 with through holes on the surface is installed horizontally between the moving block 8 and the connecting block 9 through a bolt and nut assembly, and the drilling equipment is installed using the support plate 10.

[0021] See also Figure 3-4The limiting device 3 includes a plug 30 with a conical seal at the bottom. The outer wall of the plug 30 is respectively provided with a connecting thread 31 and a spiral leaf 32. The plug is connected to the fixing plate 2 by the connecting thread 31. The spiral leaf 32 is convenient for being screwed into the soil for fixing. A limiting plate 33 with a bearing is fixed to the top of the inner cavity of the plug 30. The limiting plate 33 is vertically installed with a rotating shaft 34 with a coaxial regular hexagonal plate fixed on the top through the bearing. A vertical rod 35 is coaxially fixed to the bottom of the rotating shaft 34. Arc rods 36 are evenly fixed at horizontal staggered intervals on both sides of the outer wall of the vertical rod 35. The outer wall of the arc rod 36 is slidably connected with a cone rod 37 horizontally penetrating and inserted under the outer wall of the plug 30. A regular hexagonal column 38 is fixedly sleeved on the top of the outer wall of the plug 30.

[0022] The locking nut 39 which fits the upper surface of the limit plate 33 is screwed on the outer wall of the rotating shaft 34 to limit the rotating shaft 34 to prevent loosening so that the sharp part of the arc rod 36 drives the cone rod 37 to move and affect the connection stability. The outer wall of the arc rod 36 is installed with a slider through an arc groove, and the slider is connected to the inner end of the cone rod 37 through a hinge. The arc rod rotates to make the slider slide along the arc groove, thereby pushing the cone rod 37 to move. The inner side of the moving block 8 is horizontally fixed with an electric latch 11 which penetrates and is inserted into the surface of the extruded optical axis 5. The electric latch 11 adopts a power-off retractable type. At the same time, the outer end of its plug rod is fixed to the arc friction block that fits the optical axis 5, and is connected in series to the control circuit that controls the low-speed forward and reverse motor 7. When the low-speed forward and reverse motor 7 is powered on, the electric latch 11 is powered on and retracted, separated from the optical axis 5, and does not affect the up and down movement of the support plate 9. When the low-speed forward and reverse motor 7 stops working, its plug rod extends out to extrude the optical axis 5, thereby improving stability and preventing the screw pair 6 from being limited alone, affecting its service life.

[0023] When using the utility model of temporary support for geological drilling in water conservancy engineering: the column 1 and the fixed plate 2 are installed by bolt and nut assemblies, and then the support plate 9 is installed between the moving block 8 and the connecting block 9 by the bolt and nut assembly, and the drilling equipment is installed on the support plate 9, and finally the whole is fixed on the surface of the location to be drilled by the limit device 3, and the low-speed forward and reverse motor 7 is reversed by the reverse switch, and the height of the support plate 9 can be adjusted up and down in cooperation with the lead screw pair 6 to complete the drilling;

[0024] When using the limit device 3 for fixing, the insert tube 30 is inserted into the soil by rotating the regular hexagonal column 38 with a wrench, and then the rotating shaft 34 with a regular hexagonal plate on the top is rotated with the wrench. The rotating shaft 34 drives the arc rod 36 to rotate, thereby causing the conical rod 37 slidably engaged with it to move inward and outward. When moving outward, the conical rod 37 penetrates the insert tube 30 and is inserted into the soil, so that the overall connection is stable and the movement of the fixing plate 2 is prevented.

[0025] It is worth noting that the electric bolt lock and low-speed forward and reverse motor used in this solution are both commercially available products, and their power connection control method belongs to the existing mature technology. Their electrical connection relationship, specific circuit structure and product model will not be described in detail here.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
