Description

Technical Field

[0001] The invention belongs to the technical field of cable mapping auxiliary equipment, and in particular relates to a power cable mapping bracket and a use method thereof. Background Art

[0002] Surveying and mapping literally means measuring and drawing. It is based on computer technology, optoelectronic technology, network communication technology, space science, and information science, with global navigation satellite positioning system, remote sensing, and geographic information system as the technical core. It selects existing feature points and boundaries on the ground and obtains graphics and location information reflecting the current situation of the ground through measurement methods for engineering construction, planning and design, and administrative management. In power engineering, when conducting cable surveying and mapping, it is necessary to use a support bracket for cooperation. For example, in a foldable support bracket for power cable surveying and mapping, the support legs are hinged to achieve a retractable function, which is convenient for carrying. When surveying and mapping work is in progress, it is sometimes necessary to move multiple points to measure. When moving, the support legs need to be folded and put away first, and then opened and placed after the surveyor carries them to the new point. The process is very cumbersome. In addition, the existing surveying and mapping instruments are not stable enough when connected to the support bracket, which is not convenient for picking up and placing. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a power cable mapping bracket and a method of use to solve the problems raised in the background technology.

[0004] The objective of the present invention is achieved in this way: a power cable surveying and mapping bracket, which includes a support and a bearing platform, wherein legs are symmetrically hingedly arranged below the support, a bearing platform is arranged on the upper side of the support, the bearing platform includes a bottom support and a top plate, a worm gear is arranged inside the bottom support through a bearing, a worm shaft is screwed on the side of the worm gear, a handle is arranged on the end of the worm shaft, the upper side of the worm gear is fixedly connected to the top plate through a connecting block, and a chuck is arranged on the surface of the top plate.

[0005] The interior of the supporting leg is a hollow structure, and a telescopic rod is arranged in the middle of the supporting leg.

[0006] A clamping groove is arranged on the surface of the supporting leg, a positioning screw is arranged on the outer side of the telescopic rod, the positioning screw extends out of the clamping groove, and a rotary block is screwed on the outer side of the positioning screw.

[0007] A clamping frame is arranged at the bottom of the supporting leg, a conversion foot is arranged inside the clamping frame, and the conversion foot comprises a supporting tip and a roller.

[0008] A square groove is arranged on the side of the clamp frame, a round groove is arranged on the lower side of the square groove, and a square shaft is arranged in the middle of the conversion foot.

[0009] The diagonal line of the square shaft matches the diagonal line of the square groove, and the diameter of the circular groove is larger than the diagonal line of the square shaft.

[0010] A clamping mechanism is arranged inside the top plate, and the clamping mechanism includes a turntable, a main slider and a slave slider. The turntable is sleeved on the outside of the support shaft, and bent rods are arranged between the turntable and the main slider and the slave slider. The upper sides of the main slider and the slave slider are fixedly connected to the chuck, and the main slider and the slave slider are clamped to the top plate through limiting grooves. A driving mechanism is arranged on the lower side of the clamping mechanism.

[0011] The driving mechanism includes a driving screw, a turning handle is provided at the end of the driving screw, a sleeve is symmetrically threadedly provided on the outer side of the driving screw, the internal threads of the two sleeves are in opposite directions, a push head is provided on the lower side of the main slider, and a hinge rod is hingedly provided between the sleeve and the push head.

[0012] A method for using a power cable surveying and mapping bracket comprises the following steps: Step 1: Before use, ensure that all parts of the device are intact, especially the key parts such as the legs, supports, and clamping mechanisms, and choose a flat and stable site to install and use the bracket; Step 2: Adjust the angle and position of the telescopic rod as needed to make the legs reach the appropriate length and stability, and fix the telescopic rod with the clamping groove and the rotating block to ensure that the legs will not shake; Step 3: Place the surveying and mapping instrument on the top of the carrier, drive the driving screw to rotate by turning the handle, push the main slider to move through the sleeve and hinge rod, and then drive the turntable to rotate to drive the bending rod and the slave slider to move, so as to adjust the position and clamping force of the chuck to stably clamp the surveying and mapping instrument; Step 4: Start and debug the surveying and mapping instrument to ensure its accuracy and precision in order to obtain accurate surveying and mapping results. After the device is used, organize and store the device, recover the tools and equipment, and clean up the site.

[0013] The beneficial effects of the present invention are as follows: when the device is in use, the overall height of the device can be further adjusted by adjusting the length of the telescopic rod to meet the needs of different surveying and mapping scenarios.

The support tips are suitable for providing sufficient support force during the surveying and mapping process; the rollers facilitate the movement and transportation of the device, thereby improving work efficiency. By rotating the handle at the end of the worm shaft, the worm wheel can be driven to rotate using the bearing inside the bottom bracket. Therefore, the rotation of the worm wheel will drive the top plate to rotate synchronously, thereby realizing flexible adjustment of the surveying and mapping angle direction of the support platform. The clamping mechanism includes a turntable, a main slider and a slave slider, which are connected by a bent rod to form a stable clamping frame. The driving mechanism realizes the synchronous movement of the main slider and the slave slider through the threaded cooperation of the driving screw and the sleeve. The upper sides of the main slider and the slave slider are fixedly connected to the chuck, which can firmly clamp the surveying and mapping instrument to prevent it from sliding or falling off during the surveying and mapping process.

[0025] When the present invention is used, a relatively flat and stable site is selected to ensure that the support 1 will not tilt or collapse during use. Place the support 1 vertically, slowly expand each leg 2 to a suitable angle, ensure that they can stably support the bearing platform 3, place the surveying and mapping instrument on the upper side of the bearing platform 3, and when the horizontal angle of the surveying and mapping instrument needs to be adjusted, hold the handle 8 and gently rotate the worm shaft 7, which will drive the worm wheel 6 to rotate on the bearing in the bottom bracket 4. Since the worm wheel 6 and the top plate 5 are fixedly connected by the connecting block 9, the rotation of the worm wheel 6 will drive the top plate 5 to rotate, and then drive the surveying and mapping instrument to rotate, and the horizontal angle of the surveying and mapping can be adjusted. This device can provide a portable and stable support platform for power cable surveying and mapping. It can also be extended to other surveying and mapping scenarios that require stable support and clamping, providing efficient and accurate support for surveying and mapping work. Example

[0026] like Figure 1-6As shown, a power cable mapping bracket includes a support 1 and a bearing platform 3, wherein the support 1 is symmetrically hinged with legs 2 below, the support 1 is provided with a bearing platform 3 on the upper side, the bearing platform 3 includes a bottom support 4 and a top plate 5, a worm gear 6 is provided inside the bottom support 4 through a bearing, a worm shaft 7 is screwed on the side of the worm gear 6, a handle 8 is provided at the end of the worm shaft 7, the upper side of the worm gear 6 is fixedly connected to the top plate 5 through a connecting block 9, and a chuck 10 is provided on the surface of the top plate 5.

[0027] For better effect, the inside of the supporting leg 2 is a hollow structure, and a telescopic rod 11 is arranged in the middle of the supporting leg 2. The hollow structure inside the supporting leg 2 allows the telescopic rod 11 to move freely therein.

[0028] For better effect, the surface of the leg 2 is provided with a clamping groove 13, and the outer side of the telescopic rod 11 is provided with a positioning screw 14, the positioning screw 14 extends out of the clamping groove 13, and the outer side of the positioning screw 14 is screwed with a rotary block 15. The positioning screw 14 can move inside the clamping groove 13, and the position of the positioning screw 14 can be fixed by tightening the rotary block 15, thereby determining the length of the telescopic rod 11.

[0029] For better effect, a clamping frame 13 is arranged at the bottom of the supporting leg 2 , and a conversion foot 12 is arranged inside the clamping frame 13 . The conversion foot 12 includes a supporting tip 19 and a roller 20 .

[0030] For better effect, the side of the clamp frame 13 is provided with a square groove 17, the lower side of the square groove 17 is provided with a round groove 18, and the middle of the conversion foot 12 is provided with a square shaft 21.

When the horizontal angle of the surveying and mapping instrument needs to be adjusted, hold the handle 8 and gently rotate the worm shaft 7, which will drive the worm wheel 6 to rotate on the bearing in the bottom bracket 4. Since the worm wheel 6 and the top plate 5 are fixedly connected by the connecting block 9, the rotation of the worm wheel 6 will drive the top plate 5 to rotate, and then drive the surveying and mapping instrument to rotate, and the power cable can be surveyed and mapped at multiple horizontal angles. Further, in order to facilitate the adjustment of the length of the leg 2 and facilitate the movement of the device, the positioning screw 14 moves up and down in the clamping groove 13, thereby driving the telescopic rod 11 to extend and retract inside the leg 2 to achieve the purpose of adjusting the overall height of the equipment. The rotating block 15 can clamp the rotating block 15 on the outside of the clamping groove 13. According to specific needs, choose to use the support tip 19 or the roller 20. When it is necessary to place it stably for surveying and mapping operations, choose to use the support tip 19.

The support 1 is placed vertically, and each leg 2 is slowly expanded to a suitable angle to ensure that they can stably support the bearing platform 3. The surveying and mapping instrument is placed on the upper side of the bearing platform 3. When the horizontal angle of the surveying and mapping instrument needs to be adjusted, hold the handle 8 and gently rotate the worm shaft 7, which will drive the worm wheel 6 to rotate on the bearing in the bottom bracket 4.
