Description

Technical Field

[0001] The present invention relates to the technical field of indoor surveying and mapping, and in particular to an indoor design surveying and mapping device. Background Art

[0002] The perpendicularity of the indoor wall is very important. It not only affects the user experience of the house, but also relates to the structural safety and stability of the entire house. Therefore, when conducting indoor design, it is necessary to survey the perpendicularity of the wall.

[0003] After retrieval, the Chinese patent document with the publication number CN221826179U discloses a device for measuring the perpendicularity of a concrete wall, which relates to the technical field of building surveying, and includes a support, a telescopic vertical rod arranged on the support, a wire winding wheel arranged at the bottom of the telescopic vertical rod, a measuring scale horizontally arranged in the middle of the telescopic vertical rod, an upper cross bar horizontally arranged at the top of the telescopic vertical rod, a wire and a plumb bob. A fixed pulley assembly is arranged on the upper cross bar. One end of the wire is wound on the wire winding wheel, and the other end passes around the fixed pulley assembly and is connected to the plumb bob. Compared with the prior art, the wall perpendicularity measuring device provided by this patent is simple to use, more convenient to adjust, improves work efficiency, can be operated by only one person, and does not require working at heights, which is safer.

[0004] Based on the above retrieval and in combination with the prior art, it is found that: currently, when measuring the perpendicularity of the wall, the method of using a plumb line and a plumb bob is relatively convenient. However, due to the existence of the plumb bob, it is difficult for the plumb line to completely adhere to the wall. Therefore, a measuring scale is often equipped to assist in recording. However, this method still has the problem that the change phenomenon during measurement is not intuitive enough. At the same time, when the wall angle deviation is small, the scale change on the measuring scale is also relatively small, which is not convenient for recording, and it is easy to introduce human reading errors. Therefore, there are limitations. Summary of the Invention

Detailed implementation mode

[0020] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0021] The present invention provides an indoor design surveying and mapping device by improvement. The technical solution of the present invention is as follows: As Figures 1 to 10 shown, the embodiment of the present invention provides an indoor design surveying and mapping device, including a base 1. An installation vertical plate 5 and a hollow vertical plate 2 are fixedly installed on the top of the base 1. A detection component is installed on the installation vertical plate 5, and a plumb line component is installed on the top of the hollow vertical plate 2; The detection component includes a hydraulic rod 501 fixedly installed on one side of the installation vertical plate 5. The end of the extension rod of the hydraulic rod 501 is fixedly installed with a slide frame 6. A slide rod 601 is slidably installed on the slide frame 6, and a guide wheel 602 is rotatably installed at the end of the slide rod 601; Through the above structure, when the device is attached to one side of the wall, the hydraulic rod 501 can be controlled to start, and it can push the slide frame 6 and the slide rod 601 to move, and use the guide wheel 602 to move on the wall to realize the detection of the wall verticality.

[0022] The plumb line assembly includes a top vertical rod 201 fixedly installed at the top end of the hollow vertical plate 2. The top vertical rod 201 has an L-shaped structure. One end of the bottom of the top vertical rod 201 is fixedly connected to a pair of plumb lines 202, and the bottom ends of the two plumb lines 202 are both fixedly connected to plumb bob blocks 203. A scale plate 9 is fixedly arranged on the side of the slide rod 601 close to the plumb line 202. With the above structure, by using the provided plumb line 202 and plumb bob block 203, the plumb line 202 can be used as a reference with the wall surface to detect the verticality of the indoor wall surface. On the other hand, when the indoor wall surface is not vertical, the hydraulic rod 501 pushes the slide rod 601 and the guide wheel 602 to move upward, enabling the slide rod 601 to move relative to the slide frame 6, so that a relative displacement can be generated between the scale plate 9 and the plumb line 202, facilitating observation by personnel.

[0023] On one side of the slide frame 6, a side bracket one 707 and a side bracket two 708 are fixedly installed. A terminal cylinder 7 is fixedly installed on the side bracket one 707, and a thin tube 702 is fixedly connected to the side bracket two 708. A piston push rod 701 is fixedly connected to one side of the slide rod 601, and the piston push rod 701 is slidably connected to the terminal cylinder 7. A piston rod one 703 is slidably installed inside the thin tube 702, and a first return spring 704 is sleeved on the outer side of the piston rod one 703. The two ends of the first return spring 704 are respectively fixedly connected to the piston rod one 703 and the end of the thin tube 702. A toggle block 705 is fixedly installed at the end of the piston rod one 703, and a notch 706 is formed on the toggle block 705. With the above structure, when the slide rod 601 moves relative to the slide frame 6, the slide rod 601 can drive the piston rod one 703 to move, and by using the hydraulic effect, drive the piston push rod 701 to move, as Figure 1 and Figure 6 shown. Since the inner diameter of the terminal cylinder 7 is much larger than the inner diameter of the thin tube 702, the moving distance of the piston rod one 703 will be much larger than the moving distance of the piston push rod 701. By using the toggle block 705 with the notch 706, one of the plumb lines 202 is pulled to make it vibrate, so that it can be more intuitively observed by the recording personnel.

[0024] Furthermore, the notch 706 is adapted to the plumb line 202. With this setting, when the toggle block 705 moves, it can pull the plumb line 202.

[0025] As a further solution of the present invention, connection pieces one 8 and connection pieces two 801 are respectively fixedly installed on the upper and lower sides of the slide frame 6 and the slide rod 601, and a tension spring 802 is fixedly connected between the connection pieces one 8 and the connection pieces two 801.

[0026] Furthermore, an L-shaped end block 17 is fixedly installed on the top of the sliding frame 6, and a threaded bolt 18 is threadedly installed on the L-shaped end block 17. A locking hole that matches the threaded bolt 18 is opened on the top of the sliding rod 601. When the threaded bolt 18 is screwed with the locking hole, the guide wheel 602 is flush with one side of the base 1; through the above structure, before and after the inspection, the sliding rod 601 can be locked and fixed by twisting the threaded bolt 18 and cooperating with the set locking hole; when conducting the inspection, the threaded bolt 18 can be rotated to disengage the threaded bolt 18 from the locking hole, so that the sliding rod 601 can adapt to the wall and move.

[0027] As a further embodiment of the present invention, Figure 1 , Figure 3 , Figure 6 , Figure 9 as well as Figure 10 As shown, a reinforcement frame 301 is fixedly installed on one side of the hydraulic rod 501, a reinforcement sleeve 305 is fixed on the base 1, and an L-shaped cavity tube 3 is fixedly installed on the reinforcement frame 301 and the reinforcement sleeve 305 together, a piston double rod 302 is slidably installed inside one end of the L-shaped cavity tube 3, and a support block 303 is fixedly installed on the top of the piston double rod 302, and a conical slot 304 adapted to the weight block 203 is opened on the support block 303; through the above structure, when the support block 303 moves upward, the weight block 203 can be embedded in the conical slot 304, thereby realizing the limitation and fixation of the weight block 203.

[0028] Furthermore, an annular block 306 is fixedly installed on the inner circumferential wall of the other end of the L-shaped cavity tube 3, and a piston plate 2 307 slidably connected to the L-shaped cavity tube 3 is arranged above the annular block 306, and a return spring 308 is fixedly connected between the annular block 306 and the piston plate 2 307; through the above structure, when the surveying is completed, the hydraulic rod 501 is retracted and pulls the L-shaped mounting plate 603 to move downward, and when the hydraulic rod 501 is completely retracted, the resistance rod 604 on the L-shaped mounting plate 603 , which can push the piston plate 2 307 in the L-shaped cavity tube 3, and use the hydraulic effect to push the piston double rod 302 and the support block 303 at the other end of the L-shaped cavity tube 3 to rise, thereby fixing the heavy hammer block 203; conversely, when the hydraulic rod 501 is extended, under the potential energy of the return spring 2 15 and the gravity of the support block 303, the piston double rod 302 and the support block 303 can be lowered again, and the support block 303 can be automatically separated from the heavy hammer block 203 for verticality detection.

[0029] As a further solution of the present invention, an L-shaped mounting plate 603 is fixedly installed at one end of the bottom side of the sliding frame 6, and a pair of ball head rods 13 are slidably installed on the L-shaped mounting plate 603, and a piston plate 14 is fixedly installed at the bottom end of the ball head rods 13, a pair of mounting hoops 12 are fixed on the bottom side of the L-shaped mounting plate 603, and a liquid storage cylinder 19 is fixedly installed on the mounting hoops 12, a reset spring 2 15 is fixedly connected between the ball head rod 13 and the L-shaped mounting plate 603, and a resistance rod 604 for resisting the piston plate 2 307 is fixedly installed at one end of the bottom of the L-shaped mounting plate 603.

[0030] Furthermore, the bottom end of each liquid storage cylinder 19 is fixedly connected to a U-shaped bottom tube 16, and a T-block 10 is fixedly installed at the bottom of the slide rod 601, and both ends of the T-block 10 are provided with side arc surfaces 11; through the above structure, when the slide rod 601 moves, it can drive the T-block 10 to move, so that it can resist the corresponding ball head rod 13 and push the piston plate 14 to move downward, thereby pushing the liquid in the liquid storage cylinder 19 into the U-shaped bottom tube 16. At the same time, as shown in the attached Figure 7 As shown, the inner diameter of the liquid storage cylinder 19 is much larger than the inner diameter of the U-shaped bottom tube 16. Therefore, when the piston plate 14 moves downward, the liquid level in the U-shaped bottom tube 16 will rise significantly. At the same time, the outer wall of the U-shaped bottom tube 16 can also be provided with a distance scale, so as to make it easier for personnel to observe and record.

[0031] As a further embodiment of the present invention, Figures 1 - 3 As shown, a stand block 4 is fixedly mounted on the top of the base 1 , and a bubble level 401 is fixedly mounted on the top of the stand block 4 .

[0032] Furthermore, a bottom cylinder 101 is fixedly installed at the bottom corner of the base 1, and a piston column 102 is slidably installed inside the bottom cylinder 101, the bottom end of the piston column 102 is fixedly connected to a brake wheel 103, a support spring 105 is sleeved on the outer side of the piston column 102, and the two ends of the support spring 105 are respectively fixedly connected to the piston column 102 and the bottom of the bottom cylinder 101, and a threaded push rod 104 coaxially arranged with the bottom cylinder 101 is threadedly installed at the corner of the base 1, and a push rod 106 is fixedly installed on the base 1; through the above structure, the threaded push rod 104 can be rotated to adjust the angle of the base 1, and the bubble level 401 can be used to ensure that the base 1 is in a horizontal state during detection, thereby ensuring the reliability of the detection result.

[0033] The specific working method is: when in use, use the brake wheel 103 to move the device to one side of the wall to be tested. When one side of the base 1 is in contact with the wall, brake the brake wheel 103, and adjust the angle of the base 1 by rotating the threaded rod 104, and cooperate with the bubble level 401 to ensure that the base 1 is in a horizontal state during the test; after completion, rotate the threaded bolt 18 to disengage the threaded bolt 18 from the lock hole; use the control to start the hydraulic rod 501, and use it to push the slide frame 6 and the slide rod 601 to move, and use the guide wheel 602 to move on the wall to achieve the verticality of the wall. Detection; when the hydraulic rod 501 is extended, under the potential energy of the return spring 215 and the gravity of the support block 303, the piston double rod 302 and the support block 303 are lowered again, and the support block 303 is automatically separated from the weight block 203. At this time, the vertical line 202 is used as a reference with the wall surface to detect the verticality of the indoor wall surface; when the indoor wall surface is not vertical, the hydraulic rod 501 pushes the slide bar 601 and the guide wheel 602 to move upward, so that the slide bar 601 moves compared with the slide frame 6, so that the scale plate 9 and the vertical line 202 can be relatively displaced, so that personnel can observe; At the same time, when the slide rod 601 moves relative to the slide frame 6, the slide rod 601 drives the piston rod 703 to move, and utilizes the hydraulic effect to drive the piston push-pull rod 701 to move, such as Figure 1 and Figure 6 As shown, since the inner diameter of the end tube 7 is much larger than the inner diameter of the capillary 702, the moving distance of the piston rod 703 will be much larger than the moving distance of the piston push-pull rod 701, and the toggle block 705 with a notch 706 is used to pull one of the vertical lines 202 to make it shake, so that it can be observed more intuitively by the recording personnel; When the slide bar 601 moves, the T-block 10 is driven to move, thereby contacting the corresponding ball rod 13 and pushing the piston plate 14 to move downward, thereby pushing the liquid in the liquid storage cylinder 19 into the U-shaped bottom tube 16. Figure 7 As shown, the inner diameter of the liquid storage cylinder 19 is much larger than the inner diameter of the U-shaped bottom tube 16. Therefore, when the piston plate 14 moves downward, the liquid level in the U-shaped bottom tube 16 will rise significantly. At the same time, the outer wall of the U-shaped bottom tube 16 can also be provided with a distance scale, so as to make it easier for personnel to observe and record. When the surveying is completed, the hydraulic rod 501 is retracted and pulls the L-shaped mounting plate 603 to move downward. When the hydraulic rod 501 is completely retracted, the resistance rod 604 on the L-shaped mounting plate 603 pushes the piston plate 2 307 in the L-shaped cavity tube 3, and uses the hydraulic effect to push the piston double rod 302 and the support block 303 at the other end of the L-shaped cavity tube 3 to rise, thereby fixing the heavy hammer block 203.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
