Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction equipment, in particular to a guide rail type spiral anchor drilling machine for temporary anchoring. Background Art

[0002] The spiral anchor foundation is a new form of transmission line tower foundation. No foundation pit excavation is required during the construction of the spiral anchor. The spiral anchor rod is rod-shaped with spiral blades at the end. The torque is applied through the anchor rod to screw the spiral blades into the deeper soil. The disturbance to the soil is small, and the inherent strength of the original soil can be fully utilized to improve the bearing capacity.

[0003] In application scenarios with relatively simple construction, such as fixed capstans, tensioners, steering pulleys, and temporary pull lines, the use of traditional large spiral anchor drilling machines is often "overkill", increasing construction costs. Moreover, large spiral anchor drilling machines are large in size and not practical in some scenarios. Therefore, a construction equipment suitable for small spiral anchors is needed. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a guide rail type spiral anchor drilling machine for temporary anchoring in response to the above-mentioned technical deficiencies. The spiral anchor drilling machine is suitable for construction scenarios with low drilling depth requirements, has a small size and does not take up space, and can reduce construction costs.

[0005] The technical solution adopted by the utility model is: to provide a guide rail type temporary anchoring spiral anchor drilling machine, comprising a traction power vehicle, the rear end of which is connected to a drilling guide mechanism through a mounting member;

[0008] To further optimize this technical solution, a guide rail type temporary anchoring spiral anchor drilling machine has brackets fixed on the upper and lower sides of the left vertical beam respectively; a reversing switch is installed on the side where the two brackets are close to each other; the reversing switch corresponds to the bracket and is used to control the reversing of the hydraulic motor reducer.

[0009] To further optimize the technical solution, the output end of the hydraulic motor reducer of a guide rail type temporary anchoring spiral anchor drilling machine is detachably connected to the drilling anchor through a connecting piece.

[0010] To further optimize the technical solution, an angle measuring instrument is fixed on the support frame of a guide rail type temporary anchoring spiral anchor drilling machine.

[0011] The beneficial effects of the present invention are:

[0012] The support frame provides support for the drilling anchor, allowing the traction vehicle to carry the drilling anchor to the construction site. A reduction motor is fixed to the upper end of the left vertical beam, driving the upper horizontal shaft.

Guide rails are fixed vertically to each vertical beam, with a support plate connected between them. The support plate slides along the guide rails. A chain is installed vertically at the rear and fixed to the support plate. The chain drives the support plate to slide along the guide rails, thereby driving the base up and down, applying downward pressure to the drilling anchor. A hydraulic motor reducer drives the drilling anchor. Combined with the chain-driven movement of the support plate, drilling construction is completed at the designated location.

DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] like Figure 1 As shown, a guide rail type temporary anchoring spiral anchor drilling machine includes a traction power vehicle 1, the rear end of which is connected to a drilling guide mechanism through a mounting member;

[0019] like Figure 2-3 As shown, the drilling guide mechanism includes a support frame 2 connected to the rear side of the mounting member; the support frame 2 is arranged vertically; the support frame 2 includes vertical beams 3 on the left and right sides; a plurality of cross beams 4 are fixedly connected between the two vertical beams 3 from top to bottom; a carrier 5 is connected between the front ends of the two vertical beams 3; the carrier 5 is connected to the mounting member; a cross shaft 6 is respectively provided between the upper ends and the lower ends of the two vertical beams 3; the end of the cross shaft 6 rotates with the corresponding vertical beam 3; a sprocket 7 is respectively sleeved and fixed on the left and right sides of the cross shaft 6; the upper and lower ends of the same side are connected. The two sprockets 7 are connected by a chain 8; a reduction motor 9 is fixed to the upper end of the left vertical beam 3 for driving the upper horizontal shaft 6 to rotate; guide rails 10 are fixed vertically on the vertical beams 3; a support plate 11 is connected between the two guide rails 10; the support plate 11 is slidably connected to the guide rails 10; the rear side of the chain 8 is vertically arranged and fixed to the support plate 11; a base 12 is fixed on the support plate 11; a hydraulic motor reducer 13 is fixed on the base 12; the output end of the hydraulic motor reducer 13 is vertically downward and coaxially connected to the drilling anchor 14.

[0020] The traction vehicle 1, carrying the drilling guide mechanism, can be driven to the drilling construction location. Subsequently, by starting the reduction motor 9 and the hydraulic motor reducer 13, the chain 8 drives the support plate 11 to move vertically downward, gradually pressing the rotating drilling anchor 14 downward, thereby completing the construction process of drilling the anchor hole at the designated location. The traction vehicle 1 can adopt various existing tractors. By adding the drilling guide mechanism, it can meet the construction scenarios with lower drilling depth requirements, eliminating the need for dedicated large-scale drilling equipment, saving costs and improving practicality.

[0021] By controlling the transmission of the chain 8 through the reduction motor 9, the support plate 11 is driven to slide up and down along the guide rail 10, thereby controlling the drilling depth of the drilling anchor 14. Moreover, the height position of the support plate 11 at the rear side of the vertical beam 3 can intuitively reflect the drilling depth of the drilling anchor 14, making it more convenient to control the drilling depth. Since the drilling anchor 14 rotates continuously during drilling and soil adheres to the surface, the method in this technical solution is more convenient and reliable than determining the drilling depth by observing the depth of the drilling anchor 14 itself into the ground. In order to further clearly reflect the drilling depth, a scale value reflecting the drilling depth can also be set on the vertical beam 3. The drilling depth of the drilling anchor 14 can be directly displayed by the correspondence between the support plate 11 and the scale value.

[0022] The transmission of the chain 8 not only drives the smooth sliding of the support plate 11 along the guide rail 10, but also provides the down pressure for the drilling of the drilling anchor 14, and the process is realized only by the control of the speed reducer motor 9, so that the structure is simplified and the mechanical efficiency is improved.

[0023] As shown in Figure 2-3 The mounting member comprises a positioning frame 15 fixed to the traction power vehicle 1, a corner motor 16 fixed to the positioning frame 15, and the output end of the corner motor 16 is horizontally rearward and fixed to the bearing frame 5. The support frame 2 as a whole can be rotated by a certain angle through the corner motor 16, so that the drilling anchor 14 can also be inclined by a certain angle, which is suitable for the situation that the anchor hole needs to be inclined by a certain angle, thereby improving the application range of the technical scheme.

[0024] As shown in Figure 2 The left vertical beam 3 is fixed with a bracket 17 on the upper side and the lower side respectively; the side close to each other of the two brackets 17 is respectively provided with a reversing switch 18; the reversing switch 18 corresponds to the support plate 11 and is used for controlling the reversing of the hydraulic motor speed reducer 13. The up-down moving range of the support plate 11 can be controlled through the reversing switch 18, so as to ensure the construction reliability of the drilling anchor 14 and avoid the interference of the parts during the operation of the equipment.

[0025] As shown in Figure 2 The output end of the hydraulic motor speed reducer 13 is detachably connected with the drilling anchor 14 through a connecting piece 19. The connecting piece 19 can adopt a flange plate, a connecting sleeve or the like structure, so as to facilitate the transportation or maintenance of the drilling anchor 14 after being disassembled.

[0026] As shown in Figure 2-3 An angle measuring instrument 20 is fixed to the support frame 2. The angle measuring instrument 20 can measure the inclination angle of the drilling anchor 14, especially after the support frame 2 is rotated by a certain angle through the control of the corner motor 16, so that the angle can be more intuitively reflected, and the control of the drilling angle is more reliable when the drilling anchor hole is inclined.
