Description

Technical Field

[0002] Fiber optic drilling rigs, also known as photovoltaic drilling rigs, are mechanical equipment specially used for drilling holes in mountainous areas. In order to accurately drill holes of appropriate size, photovoltaic drilling rigs are generally composed of a drill bit and a motor. The motor drives the drill bit to rotate, and the drill bit is used to drill a hole in the ground. The drill bit is generally of adjustable size, and the size and depth of the hole can be freely adjusted as needed.

[0003] With the continuous development of the photovoltaic industry, various types of fiber optic drilling rig structures have also appeared in recent years. For example, in the patent document with patent publication number CN206128066U, a photovoltaic pile driver with high-precision positioning is disclosed, whose main structure includes a mobile platform, on which a rotating mechanism is arranged; a drill mast, which is arranged on the rotating mechanism, and a first antenna is arranged on the drill mast; a vibrating hammer, which is vertically slidably arranged on the drill mast, and the vibrating hammer is a high-frequency hydraulic vibrating hammer, and a clamp for fixing the pipe pile is arranged at the lower end of the vibrating hammer, and a second antenna is arranged on the top of the vibrating hammer, and the second antenna and the clamp are not on the same vertical line.

The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 5 as shown in .

The rear end of the flip frame 2 is in a horizontal state in an idle state and the bottom is abutted against the top of a vertical support bracket 7.

A flip cylinder 8 is arranged on the rear side of the side swing mechanism, and the front end of the flip cylinder 8 is hinged to the middle of the rear side of the side swing mechanism, and the rear end of the flip cylinder 8 is movably connected to the rear side of the bottom of the flip frame 2. The drilling mechanism of the extendable optical fiber drilling rig in the utility model can drive the overall rotation of the components above it by relying on the linkage of the slewing bearing 5 on the chassis frame 3. When the chassis frame 3 is in place, the rotation of the slewing bearing 5 and the extension of the extension component can realize the displacement change in the circumferential direction and the radial direction within a certain range, which can effectively match and adapt to the needs of drilling holes in multiple circumferential positions in the positioning state, avoid damage to the ground caused by frequent movement of the whole machine, and after the whole machine is positioned in sequence, it can realize continuous operation of multiple holes and improve the drilling efficiency.

[0026] In any of the above schemes, it is preferred that the stretching assembly includes a horizontally arranged translation stretching frame 9, the inner ends of the two stretching square tubes 901 of the translation stretching frame 9 are both fitted and inserted into the cavity of the rectangular tube 601 at the corresponding position, and a first reinforcing square tube 902 and a second reinforcing square tube 903 perpendicular to the two stretching square tubes 901 of the translation stretching frame 9 are fixedly installed at intervals between the front ends, and a first lower ear seat 904 and a second lower ear seat 905 are fixedly installed at the top centers of the first reinforcing square tube 902 and the second reinforcing square tube 903.

[0027] After the extension component rotates to a matching position following the slewing bearing 5, the structure at the top of its front end can be driven to shift in its extension direction by controlling the start of the extension component, so that the operator can choose a reasonable drilling control position within a certain current range. During specific work, starting the corresponding two synchronous side thrusters can drive the translational extension frame 9 connected thereto to extend and shift in the front-to-back direction. The two synchronous side thrusters cooperate with each other to ensure the smoothness and stability of the drive shift.

An oblique upward ear seat 13 is welded to the left and right sides of the upper part of the lateral swing frame 10, and a side swing oil cylinder 14 is respectively arranged below each oblique upward ear seat 13. The top of the piston rod of the side swing oil cylinder 14 is movably hinged to the oblique upward ear seat 13, and the bottom of the cylinder barrel of the side swing oil cylinder 14 is movably hinged to the lower side ear seat 906 at the corresponding position. The two side swing oil cylinders 14 cooperate with each other in the working state, and the top of the lateral swing frame 10 is movably hinged to the front end bottom of the flip frame 2 through a horizontal hinge shaft.

[0029] Taking into account that fiber optic drilling construction generally needs to be carried out outdoors in complex mountainous conditions, the drilling rig may be located in an uneven position after the entire machine is in place. The side swing mechanism provided here can drive the leveling of the entire side swing frame 10 by controlling the extension and retraction of the side swing cylinders 14 on both sides after the entire machine is in place, so as to better cooperate with the straightening of the drilling rig body 1 installed on the top of the flip frame 2 and in a vertical working state, thereby ensuring that the drilling can meet the standard requirements and improving the accuracy of the drilling.

[0030] Among them, the drilling rig body 1 adopts a drilling rig structure capable of lifting and lowering in the prior art. Specifically, it can adopt a double-stroke anchor drilling rig structure as involved in patent application number CN202023206217.8, or it can adopt other drilling rig structures with telescopic lifting functions in the prior art, which will not be described in detail.

[0031] In any of the above schemes, it is preferred that the two synchronous side thrust members are in a synchronous telescopic state when in working state.

[0032] In any of the above schemes, it is preferred that the synchronous side thrust member includes an extension cylinder 15 horizontally arranged along the front-to-back direction, the rear end of the extension cylinder 15 is movably hinged on the welded rear ear seat 16 at the top of the rotating part of the slewing bearing 5, and the front end of the piston rod of the extension cylinder 15 is movably hinged on the ear seat fixed at the corresponding position of the rear side wall of the second reinforced square tube 903.

[0033] When working, the extension cylinder 15 can drive the extension square tube 901 movably inserted in the cavity of the corresponding rectangular tube 601 to slide forward and backward through extension and contraction, effectively ensuring the smoothness and stability of the extension square tube 901 during displacement, achieving on-demand extension into place, and improving the adaptability to complex ground during drilling.

[0034] In any of the above schemes, it is preferred that a control cylinder 18 is installed in the internal mounting cavity of the flip frame 2, the rear end of the control cylinder 18 is movably connected to the inside of the flip frame 2, and the front end of the piston rod of the control cylinder 18 is used to be movably hinged with the bottom of the drilling rig body 1 that is slidably engaged in the limiting slide groove 17 on the top of the flip frame 2, and the control cylinder 18 controls the drilling rig body 1 to slide back and forth along its length direction by telescoping.

[0035] Specific working principle: The drilling mechanism of the extendable optical fiber drilling rig is pre-installed and assembled on the drilling rig. After the installation is completed, the drilling rig is started to move into place, and the linkage of the slewing bearing 5 on the chassis frame 3 can drive the overall rotation of the components above it.

[0036] When the chassis frame 3 is in place, the rotation of the slewing bearing 5 and the extension of the extension assembly can realize the displacement change in the circumferential direction and the radial direction within a certain range, which can effectively match and adapt to the needs of drilling holes in multiple circumferential positions in the positioning state, avoid frequent movement of the whole machine to damage the ground, and after the whole machine is positioned in sequence, it can realize multiple holes and continuous operation, improving the drilling efficiency. Specifically, by controlling the start of the extension assembly, the structure at the top of its front end can be driven to achieve displacement in its extension direction, so that the operator can choose a reasonable drilling control position within the current certain range. When working, starting the corresponding two synchronous side thrusters can drive the translation extension frame 9 connected to it to stretch and shift along the front and rear directions. The two synchronous side thrusters cooperate with each other to ensure the smoothness and stability of the driving displacement. Since fiber optic drilling construction generally needs to be carried out outdoors in complex mountainous conditions, the drilling rig may be located in an uneven position after the entire machine is in place. The side swing mechanism provided here can drive the leveling of the entire side swing frame 10 by controlling the extension and retraction of the side swing cylinders 14 on both sides after the entire machine is in place, so as to better cooperate with the straightening of the drilling rig body 1 installed on the top of the flip frame 2 and in a vertical working state, thereby ensuring that the drilling can meet the standard requirements and improving the accuracy of the drilling.

[0037] From the above, it can be seen that the drilling mechanism of the extendable fiber optic drill in the utility model can rely on the extension component to drive the side swing mechanism at the top of its front end and the existing drill body 1 to complete the on-demand shift in the front and rear directions after the crawler wheel accessories and the cab accessories are installed. This can ensure that the stability of the whole machine can be adjusted in coordination with the whole machine, and the appropriate drilling point can be selected after flipping through telescoping when working on different rugged terrain; the entire structure can cooperate with the side swing mechanism to adjust the horizontal tilt angle of the drill body 1 after flipping, effectively ensuring the tilt positioning before drilling, ensuring that the drilling angle meets the set route requirements, and improving the accuracy of drilling; when driving the translation extension frame 9 to shift, the extension component can cooperate with the telescoping of the flipping cylinder 8 to effectively link the translation of the side swing mechanism at the front end and the translation of the flipping frame 2, while ensuring that the chassis frame 3 is fixed, the overall displacement of the bottom structure is achieved, thereby improving the overall displacement amplitude.
