Description

Technical Field

[0001] The invention relates to the application field of laser total station, in particular to an engineering building surveying and mapping device based on laser measurement. Background Art

[0002] A total station is a high-precision measuring instrument that integrates electronic distance measurement, electronic angle measurement, data storage and processing. It is widely used in surveying, construction, engineering surveying and geographic information systems (GIS).

[0003] The working principle of the total station is based on triangulation, laser ranging and angle measurement. It measures the distance, horizontal angle and vertical angle between the target point and the instrument, and then calculates the three-dimensional coordinates of the target point. The total station uses laser ranging, angle measurement and automatic data processing technology to achieve accurate measurement of the target point position. It does not rely on a single measurement during the measurement process, but ensures high precision and high efficiency through the comprehensive calculation of multiple angle and distance data. This makes the total station widely used in construction engineering, land surveying, mining surveying and other fields.

[0004] A total station is usually equipped with an objective lens and an eyepiece. The objective lens is usually located at the front end of the total station and is responsible for collecting and focusing light from distant targets. The eyepiece is used to observe the target. Therefore, in actual applications, especially in construction projects, dust and rain will contaminate the objective lens and eyepiece of the total station. Construction workers often choose to use a total station with a blurred lens to measure data because they do not carry the corresponding cleaning tools, which can easily lead to errors in the measurement data. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an engineering building surveying and mapping device based on laser measurement to solve the technical problems mentioned in the above background.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laser measurement-based engineering building surveying and mapping device, comprising a tripod and a total station, the top of the tripod is rotatably connected with a first mounting shell and a second mounting shell, the side of the first mounting shell is provided with a guide rod, and the outer sleeve of the guide rod is provided with a first spring, and the outer movable sleeve of the guide rod is provided with two groups of linkage plates, and the ends of the two groups of linkage plates are both provided with pushing plates, both ends of the second mounting shell are rotatably connected with cleaning components, and the side of the second mounting shell is rotatably connected with a forward and reverse threaded rod, and the outer threads of the forward and reverse threaded rod are connected with two groups of locking blocks, and the two groups of locking blocks are symmetrically arranged, and a knob is provided at one end of the forward and reverse threaded rod, and the forward and reverse threaded rod and the two groups of cleaning components are both connected by a pulley assembly for transmission.

[0007] By adopting the above technical solution, the total station can be wrapped and protected by arranging a rotatable first mounting shell and a second mounting shell on the top of the tripod. When the first mounting shell and the second mounting shell are opened, the first mounting shell and the second mounting shell can play a simple storage role. When the staff needs to calibrate and adjust the total station, the first mounting shell and the second mounting shell can temporarily store the tape measure, paper and pen carried by the staff. When the first mounting shell and the second mounting shell are closed, the total station can be wrapped. Aiming at the complex environment of the construction site, the total station is protected and the risk of damage to the total station by external forces is reduced.

[0008] The present invention is further configured such that a first sealing ring and a second sealing ring are provided on the side of the first mounting shell, and the first sealing ring and the second sealing ring are used to improve the sealing between the first mounting shell and the second mounting shell.

[0009] Preferably, the butt joint between the first mounting shell and the second mounting shell is configured as a chimeric butt joint to improve the sealing performance, and a first sealing ring and a second sealing ring are provided at the butt joint to improve the sealing effect, so that when the equipment is suddenly faced with a rainy environment, the damage to the total station caused by rain can be reduced.

[0010] The present invention is further configured such that the two groups of linkage plates and the outer wall of the first mounting shell are movably mounted by arranging a first limiting assembly.

[0011] Preferably, the stability of the movement of the two groups of linkage plates can be improved by providing a first limiting assembly.

[0012] The present invention is further configured such that the two groups of locking blocks and the outer wall of the second mounting shell are movably mounted by arranging a second limiting assembly.

[0013] Preferably, the stability of the movement of the two groups of locking blocks can be improved by providing a second limit grip.

[0014] The present invention is further configured such that the sides of the two groups of locking blocks are provided with engaging grooves matching the linkage plates.

[0015] Preferably, an engaging groove matching the linkage plate is provided on the inner side of the locking block so that the locking block can press the linkage plate to fix the linkage plate in the vertical direction and can push the linkage plate to move in the horizontal direction.

[0016] The present invention is further configured such that the cleaning assembly includes a sleeve rotatably connected to the second mounting shell, and the sleeve and the forward and reverse threaded rods are transmission-connected via a pulley assembly.

[0017] Preferably, a pulley assembly is provided so that the cleaning assembly can be driven to rotate by driving the forward and reverse threaded rods to rotate, so that the cleaning assembly can rotate and wipe the objective lens and eyepiece of the total station.

[0018] The present invention is further configured such that a bearing ring is movably installed inside the sleeve by arranging a plurality of groups of second springs, and a limiting groove is formed in the inner wall of the sleeve.

[0019] Preferably, by arranging the bearing ring and a plurality of groups of second springs, the flexible cleaning brush can contract into the interior of the sleeve.

[0020] The present invention is further configured such that a flexible cleaning brush is movably installed inside the sleeve, an outer convex ring is arranged on the outer part of the flexible cleaning brush, and the outer convex ring fits against the side surface of the bearing ring, and the outer convex ring and the limiting groove are matched with each other.

[0021] Preferably, by arranging the flexible cleaning brush, it can wipe and clean the objective lens and the eyepiece of the total station, and the flexible cleaning brush is fitted into the sleeve through the outer convex ring, and the fitting between the two is precise, so that the sleeve can better drive the flexible cleaning brush to rotate.

[0022] The present invention is further configured such that a first protective shell is arranged on the outer part of the first mounting shell, and a second protective shell is arranged on the outer part of the second mounting shell.

[0023] Preferably, by arranging the first protective shell and the second protective shell, the first mounting shell and the second mounting shell can be protected.

[0024] In summary, the present invention mainly has the following beneficial effects: 1. By arranging a rotatable first mounting shell and a second mounting shell on the top of the tripod, the present invention can wrap and protect the total station. When the first mounting shell and the second mounting shell are opened, they can play a simple storage role. When the staff needs to calibrate and adjust the total station, the first mounting shell and the second mounting shell can temporarily store the tape measures, pens and papers carried by the staff. When the first mounting shell and the second mounting shell are closed, they can wrap the total station, and in view of the complex environment of the construction site, it can protect the total station and reduce the risk of damage to the total station caused by external force factors.

[0025] 2. The present invention can simply clean the objective lens and eyepiece of the total station by setting a cleaning component. The first mounting shell and the second mounting shell are fixed by setting a linkage plate and a lock block. Rotating the left - right threaded rod will drive two lock blocks to approach each other, pressing the linkage plate to achieve the effect of closing and locking the first mounting shell and the second mounting shell. And the left - right threaded rod will continue to rotate, causing the lock block to continue to push the linkage plate to move. Since the objective lens and eyepiece of the total station often present a sunken state, the linkage plate is designed to continue to move and push two cleaning components to actively fit the objective lens and eyepiece. At the same time, when the left - right threaded rod rotates, it will drive the rotating rod of the cleaning component through the pulley assembly. Therefore, when the cleaning component starts to fit the objective lens and eyepiece, the cleaning component will rotate synchronously to wipe and clean the objective lens and eyepiece.

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] See also Figures 1 - 10 A surveying and mapping device for engineering buildings based on laser measurement includes a tripod 1 and a total station 2. The top of the tripod 1 is rotatably connected with a first mounting shell 3 and a second mounting shell 11. A guide rod 4 is arranged on the side of the first mounting shell 3, and a first spring 5 is sleeved on the outside of the guide rod 4. Two sets of linkage plates 6 are movably sleeved on the outside of the guide rod 4. Push plates 8 are installed at the ends of the two sets of linkage plates 6. The push plates 8 and the linkage plates 6 can be fixedly installed by setting screws, so that the push plate 8 shell can be detachable so that the flexible cleaning brush 1605 of the cleaning component 16 can be detached, or the push plate 8 and the linkage plate 6 can be removed. The space can also be set as a damped rotation connection, and the folding push plate 8 also facilitates the disassembly of the flexible cleaning brush 1605 of the cleaning component 16. The cleaning components 16 are rotatably connected at both ends of the second mounting shell 11. The cleaning components 16 are used to wipe and clean the objective lens and eyepiece of the total station 2, and the side of the second mounting shell 11 is rotatably connected with the positive and negative threaded rod 12, and the external threads of the positive and negative threaded rod 12 are connected with two groups of locking blocks 13, and the two groups of locking blocks 13 are symmetrically arranged, and a knob 15 is arranged at one end of the positive and negative threaded rod 12, and the positive and negative threaded rod 12 and the two groups of cleaning components 16 are connected by a pulley assembly 17 for transmission.

[0031] In the above embodiments, please refer to Figure 5A first sealing ring 9 and a second sealing ring 10 are arranged on the side of the first mounting shell 3. The first sealing ring 9 and the second sealing ring 10 are used to improve the sealing between the first mounting shell 3 and the second mounting shell 11. The docking point of the first mounting shell 3 and the second mounting shell 11 is arranged to be a chimeric docking point to improve the sealing. The first sealing ring 9 and the second sealing ring 10 are arranged at the docking point to improve the sealing effect, so that when the equipment is suddenly faced with a rainy environment, the damage of rain to the total station 2 can be reduced.

[0032] In the above embodiments, please refer to Figure 5 The two groups of linkage plates 6 and the outer wall of the first mounting shell 3 are movably mounted by setting a first limiting component 7. By setting the first limiting component 7, the movement stability of the two groups of linkage plates 6 can be improved.

[0033] In the above embodiments, please refer to Figure 6 The two groups of locking blocks 13 and the outer wall of the second mounting shell 11 are movably mounted by setting a second limiting assembly 14. The second limiting assembly 14 can improve the movement stability of the two groups of locking blocks 13.

[0034] In the above embodiments, please refer to Figure 6 , Figure 9 and Figure 10 The sides of the two sets of locking blocks 13 are provided with engaging grooves matching the linkage plate 6. By providing an engaging groove matching the linkage plate 6 on the inner side of the locking block 13, the locking block 13 can press the linkage plate 6 to fix the linkage plate 6 in the vertical direction, and can push the linkage plate 6 to move in the horizontal direction.

[0035] In the above embodiments, please refer to Figure 7 The cleaning assembly 16 includes a sleeve 1601 rotatably connected to the second mounting shell 11, and the sleeve 1601 and the forward and reverse threaded rod 12 are connected by a pulley assembly 17. By setting the pulley assembly 17, the cleaning assembly 16 can be driven to rotate by driving the forward and reverse threaded rod 12 to rotate, so that the cleaning assembly 16 can rotate to wipe the objective lens and eyepiece of the total station 2.

[0036] In the above embodiments, please refer to Figure 8 A carrying ring 1603 is movably installed inside the sleeve 1601 by setting multiple sets of second springs 1602, and a limiting groove 1604 is opened on the inner wall of the sleeve 1601. By setting the carrying ring 1603 and multiple sets of second springs 1602, the flexible cleaning brush 1605 can be retracted into the interior of the sleeve 1601.

[0037] In the above embodiments, please refer to Figure 8, a flexible cleaning brush 1605 is movably installed inside the sleeve 1601, and an outer convex ring 1606 is arranged outside the flexible cleaning brush 1605. The outer convex ring 1606 fits against the side surface of the bearing ring 1603, and the outer convex ring 1606 matches the limiting groove 1604. By arranging the flexible cleaning brush 1605, the objective lens and the eyepiece of the total station 2 can be wiped and cleaned. The flexible cleaning brush 1605 is embedded in the sleeve 1601 through the outer convex ring 1606, and the fitting between the two is precise, so that the sleeve 1601 can drive the flexible cleaning brush 1605 to rotate better.

[0038] In the above embodiment, specifically, please refer to again Figure 1 , a first protective shell 18 is arranged outside the first mounting shell 3, and a second protective shell 19 is arranged outside the second mounting shell 11. By arranging the first protective shell 18 and the second protective shell 19, the first mounting shell 3 and the second mounting shell 11 can be protected.

[0039] When the present invention is working specifically: when the construction worker needs to store the total station 2 after measuring the engineering data with the total station 2, first, the construction worker manually pushes the first mounting shell 3 and the second mounting shell 11 to close. At this time, the two cleaning assemblies 16 are in a state away from the objective lens and the eyepiece of the total station 2. The driving knob 15 is rotated, and the rotation of the knob 15 drives the forward and reverse threaded rod 12 to rotate. The forward and reverse threaded rod 12 drives the two cleaning assemblies 16 to rotate through the two pulley assemblies 17. At this time, since the cleaning assemblies 16 do not fit against the objective lens and the eyepiece of the total station 2, the cleaning assemblies 16 will not clean the objective lens and the eyepiece of the total station 2. However, the rotation of the forward and reverse threaded rod 12 drives the two locking blocks 13 to slide along the second limiting assembly 14 and approach each other. The two locking blocks 13 approach each other until they fit against the two corresponding linkage plates 6, as Figure 9, at this time, the two groups of locking blocks 13 will compress and lock the linkage plate 6, but the positive and reverse threaded rod 12 will continue to rotate, causing the two groups of locking blocks 13 to push the two groups of linkage plates 6 to approach each other. The two groups of linkage plates 6 approaching each other will compress the first spring 5, and the two groups of linkage plates 6 approaching each other will also synchronously drive the push plate 8 to squeeze the cleaning assembly 16, causing the two groups of cleaning assemblies 16 to contract into the interior of the second mounting shell 11. Furthermore, the two groups of cleaning assemblies 16 will actively fit the objective lens and eyepiece of the total station 2 in the sunken state. The flexible cleaning brush 1605 of the cleaning assembly 16 is a flexible cleaning tool. When the flexible cleaning brush 1605 is attached to the objective lens and eyepiece, the flexible cleaning brush 1605 can still move a certain distance. When the flexible cleaning brush 1605 is squeezed by the push plate 8, the flexible cleaning brush 1605 pushes the bearing ring 1603 to move through the flexible cleaning brush 1605, and the bearing ring 1603 will compress multiple groups of second springs 1602. And due to the drive of the pulley assembly 17, the cleaning assembly 16 will also rotate synchronously. Furthermore, the sleeve 1601 will drive the flexible cleaning brush 1605 to rotate through the action of the limiting groove 1604 and the outer convex ring 1606, so that the flexible cleaning brush 1605 can slowly rotate to wipe and clean the objective lens and eyepiece of the total station 2.

[0040] The above are the steps after the total station 2 is used. Similarly, every time a construction worker needs to use the total station 2, the tripod 1 needs to be opened first and the installation angle of the tripod 1 needs to be adjusted. According to the steps, the knob 15 is rotated in the same way. After the two groups of cleaning assemblies 16 clean the objective lens and eyepiece of the total station 2, they will move away from each other so that the staff can manually open the first mounting shell 3 and the second mounting shell 11. When the first mounting shell 3 and the second mounting shell 11 are opened for work, the construction worker calibrates the total station 2 and then starts working.

[0041] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations to the invention. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not contribute creatively to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
