Description

Technical Field

[0001] The invention relates to the field of rotary drilling construction, and more specifically to a rotary drilling construction positioning and guiding device. Background Art

[0002] In the process of rotary excavation, a rotary drilling rig is needed to drill pile holes or foundation pits. The accuracy of the pile hole positioning on the ground directly affects the quality of the rotary excavation. In the prior art, for some occasions with high positioning accuracy requirements, the staff first sets a center pile on the ground according to the drawings, then uses a compass to draw a circle on the ground, and then aligns the center of the rotary drill with the center pile before performing rotary excavation.

[0003] In the prior art, since the drill bit of the rotary drill is large, the construction workers cannot keep their sight at the same level with the ground whether they are standing or squatting, which leads to the problem of inaccurate alignment when aligning the center of the drill bit of the rotary drill with the center pile, resulting in inaccurate pile hole positioning, and also reduces the work efficiency of the construction work.

[0004] In response to this technical problem, a Chinese patent application numbered 201721353553.0 discloses a rotary drilling construction positioning guide device, which includes a guide cylinder and at least two construction lines, wherein the guide cylinder is cylindrical, a fixing device is provided at the bottom of the guide cylinder, and the fixing device is used to fix the positioning cylinder on the ground, and each of the construction lines is connected to the upper end of the guide cylinder, and each of the construction lines is arranged along the diameter direction of the guide cylinder, and the projections of each of the construction lines on the cross section of the guide cylinder intersect with each other. The utility model can improve the accuracy of positioning, ensure the safety of positioning work, and improve the effect of rotary drilling operations. However, during the construction process, as the depth of the drilling hole increases, the height of the guide cylinder may need to be adjusted. If the height of the guide cylinder cannot be adjusted, if a slight deviation occurs during the drilling process, it cannot be discovered and adjusted in time, which will affect the normal use of the device.

[0005] Therefore, a rotary drilling construction positioning and guiding device is proposed. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a lower guide cylinder, an upper guide cylinder, a handle, a positioning ring, a support plate, a threaded rod, a rotating handle and a connecting block. Through the setting of the positioning ring, the upper guide cylinder can be slid and positioned to avoid deviation when the upper guide cylinder is connected to the lower guide cylinder, thereby improving the comfort of workers during use and reducing the possibility of affecting work efficiency due to misalignment; through the setting of the threaded rod, the connecting block can be driven by a spiral transmission to lift the upper guide cylinder and adjust the height, so that the height of the upper guide cylinder can be adjusted according to the different depths of the pile hole and the formation conditions during rotary drilling construction, thereby reducing the installation of the equipment. The difficulty improves the efficiency of construction, and can also adapt to workers of different heights to a certain extent, so that workers can be more relaxed when working and reduce work intensity; through the setting of the connecting block, it can be fixedly connected with the upper guide cylinder, so that the threaded rod can lift the upper guide cylinder through the spiral transmission method to adjust the height; through the setting of the handle, when the guide device needs to be carried for use, the handle can facilitate the upper guide cylinder to be lifted, which is convenient for carrying and using the guide device; through the setting of the positioning ring, the upper guide cylinder can be slid and positioned to avoid displacement when the upper guide cylinder is connected to the lower guide cylinder; 2.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0022] Embodiment 1: See also Figures 1 to 3 A rotary drilling construction positioning guide device comprises a lower guide cylinder 1, both sides of the outer surface of the lower guide cylinder 1 are provided with handles 102, and the upper end surface of the lower guide cylinder 1 is provided with a positioning ring 103, the outer surface of the positioning ring 103 is slidably mounted with an upper guide cylinder 101, and the upper end outer surface of the upper guide cylinder 101 is evenly provided with a plurality of laser positioning components 3. The advantage of this arrangement is that, through the arrangement of the handle 102, when the guide device needs to be carried for use, the handle 102 can facilitate the upper guide cylinder 101 to be lifted, which is convenient for carrying and using the guide device; through the arrangement of the positioning ring 103, the upper guide cylinder 101 can be slidably positioned to avoid displacement when the upper guide cylinder 101 is connected to the lower guide cylinder 1.

[0023] A plurality of support plates 2 are evenly arranged on the outer surface of the upper end of the lower guide cylinder 1, and a threaded rod 201 is rotatably installed on the upper surface of the support plate 2, and a rotating handle 202 is arranged on the upper end surface of the threaded rod 201. The advantage of this arrangement is that, through the arrangement of the threaded rod 201, the connecting block 203 can be driven by a spiral transmission to lift the upper guide cylinder 101 and adjust the height, so that the height of the upper guide cylinder 101 can be adjusted according to the different depths of the pile holes and the formation conditions during rotary drilling construction, so as to reduce the difficulty of equipment installation and improve the efficiency of construction. When the upper guide cylinder 101 is separated from the lower guide cylinder 1, the middle part is in a hollow state, which can facilitate the construction workers to observe the internal situation.

[0024] A connecting block 203 is spirally installed on the outer surface of the threaded rod 201, and the connecting block 203 and the upper guide cylinder 101 are arranged to be fixedly connected. The advantage of this arrangement is that through the arrangement of the connecting block 203, it is possible to achieve a fixed connection with the upper guide cylinder 101, so that the threaded rod 201 can lift the upper guide cylinder 101 through a spiral transmission to adjust the height.

[0025] like Figures 4 to 6 As shown, the laser positioning assembly 3 includes a support plate 301 arranged on the outer surface of the upper end of the upper guide cylinder 101, a rotating disk 302 is rotatably installed on the upper surface of the support plate 301, and a placement seat 303 is arranged on the upper end surface of the rotating disk 302, and a laser lamp 308 is installed on the upper surface of the positioning clamping plate 306. The advantage of this arrangement is that, through the arrangement of the placement seat 303, the bidirectional spiral transmission rod 305 can be supported while facilitating the positioning and fixation of the laser lamp 308 placed on the upper surface.

[0026] Support blocks 304 are arranged on both sides of the outer surface of the placement seat 303, and a bidirectional spiral transmission rod 305 is rotatably installed on the inner surface of the support block 304. The advantage of this arrangement is that through the arrangement of the bidirectional spiral transmission rod 305, when the laser lamp 308 needs to be installed or replaced, the positioning clamp 306 installed on the outer surface can be driven by spiral transmission to slide along the outer surface of the placement seat 303 and move inward to quickly clamp the laser lamp 308, thereby improving the installation and disassembly speed of the laser lamp 308 and facilitating the replacement and use of the laser lamp 308.

[0027] A positioning clamp 306 is spirally installed on the outer surface of the bidirectional spiral transmission rod 305, and the positioning clamp 306 and the outer surface of the rotating disk 302 are set to be slidingly connected. The advantage of this setting is that through the setting of the rotating disk 302, the angle of the laser lamp 308 can be adjusted by friction rotation along the upper surface of the support plate 301 to achieve a suitable positioning angle, so as to facilitate the positioning work of the guide equipment and avoid deviations during drilling.

[0028] A buffer pad 307 is provided on the inner surface of the positioning clamp 306, and the buffer pad 307 is made of rubber material. The advantage of this arrangement is that through the arrangement of the buffer pad 307, when the positioning clamp 306 positions and clamps the laser lamp 308, the buffer pad 307 made of rubber material can be compressed and rebounded to reduce the pressure on the laser lamp 308 to protect it when it is in contact with the outer surface of the laser lamp 308, thereby reducing the pressure on the laser lamp 308 and reducing damage to the outer surface of the laser lamp 308.

[0029] like Figure 7As shown, a rotating rod 4 is provided on the lower surface of the rotating disk 302, and a damping gasket 401 is provided on the outer surface of the upper end of the rotating rod 4, and a friction connection is set between the damping gasket 401 and the upper surface of the supporting plate 2 301. The advantage of this setting is that, through the setting of the damping gasket 401, when the rotating disk 302 rotates to adjust the angle of the laser positioning component 3, the friction between the damping gasket 401 and the upper surface of the supporting plate 2 301 can slow down the rotation speed of the rotating disk 302, make the angle adjustment more precise, and avoid the rotating disk 302 rotating too much at one time to affect the angle adjustment of the laser lamp 308.

[0030] A thread groove 402 is provided on the outer surface of the lower end of the rotating rod 4, and a friction sleeve 403 is spirally installed on the outer surface of the thread groove 402, and the friction sleeve 403 and the lower surface of the support plate 301 are arranged to be frictionally fixed. The advantage of this arrangement is that, through the arrangement of the friction sleeve 403, the rotating disk 302 after the angle adjustment can be fixed by rotating along the thread groove 402 opened on the outer surface of the lower end of the rotating rod 4 and frictionally connecting with the lower surface of the support plate 301 to prevent it from loosening during use.

[0031] like Figure 8 As shown, a plurality of support plates three 5 are provided on the outer surface of the lower end of the lower guide cylinder 1, and a sliding plug rod 501 is slidably installed on the surface of the support plate three 5, and an anti-disengagement hook 502 is provided on the outer surface of the lower end of the sliding plug rod 501. The advantage of this arrangement is that, through the arrangement of the anti-disengagement hook 502, the sliding plug rod 501 can be prevented from rebounding and loosening when the sliding plug rod 501 is inserted into the ground to fix the lower guide cylinder 1; through the arrangement of the sliding plug rod 501, after the guide device is placed, the guide device can be fixed by sliding downward along the support plate three 5 and inserted into the soil, thereby ensuring the stability of the guide device when in use.

[0032] A pressure plate 503 is provided on the upper end surface of the sliding rod 501, and a lifting groove 504 is opened on the upper end surface of the pressure plate 503, and a reset spring 505 is provided on the outer surface of the sliding rod 501. The advantage of this arrangement is that through the arrangement of the reset spring 505, the sliding rod 501 can be driven to rebound and retract through the reset of the reset spring 505 when the sliding rod 501 is lifted, thereby preventing the sliding rod 501 from sliding loose when the reset device is carried, which greatly facilitates the carrying and transportation of the guide device.

[0033] Instructions for use: When the guide device is needed for positioning, first hold the handle 102 and move the lower guide cylinder 1 to the specified position. Then, press down the pressure plate 503. At this time, the sliding rod 501 with the anti-disconnection hook 502 will slide down along the support plate 3 5 and insert into the ground, thereby fixing the lower guide cylinder 1. Next, place the laser light 308 on the upper surface of the placement seat 303, rotate the bidirectional spiral transmission rod 305, drive the positioning clamping plate 306 to slide inward along the outer surface of the placement seat 303, so that the positioning clamping plate 306 with the buffer pad 307 fits tightly and clamps the laser light 308, completing the positioning and fixing of the laser light 308.

[0034] If the angle of the laser lamp 308 is to be adjusted, the friction sleeve 403 must be reversed first, so that it can be screwed out along the threaded groove 402 provided on the lower outer surface of the rotating rod 4, and the friction between the friction sleeve 403 and the lower surface of the second support plate 301 can be released. After that, the angle of the laser lamp 308 can be adjusted by rotating the rotating disk 302 along the rotating rod 4 with the damping gasket 401. After the angle of the laser lamp 308 is adjusted using the rotating disk 302, the friction sleeve 403 is tightened again to generate friction with the second support plate 301 again, thereby fixing the angle of the laser lamp 308.

[0035] During the use of the guide device, as the drilling depth increases, if the height of the guide device needs to be adjusted, the two rotating handles 202 can be rotated synchronously to drive the threaded rod 201 to rotate. At this time, the connecting block 203 will rotate along the outer surface of the threaded rod 201, and then the upper guide cylinder 101 will slide along the outer surface of the positioning ring 103 and steadily lift until it reaches the specified height position to complete the height adjustment.

[0036] After use, the sliding rod 501 is pulled upwards through the pulling groove 504 to be pulled out of the soil. At the same time, the rebound force generated by the compression of the return spring 505 will drive the sliding rod 501 to be automatically stored, so as to avoid the sliding rod 501 from shaking when carrying the guide device.

[0037] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
