Description

Technical Field

[0001] The present invention relates to the application field of laser total stations, 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. During the measurement process, it does not rely on a single measurement, but through the comprehensive calculation of multiple angle and distance data, ensuring high precision and high efficiency. 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 when used 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 being rotatably connected to a first mounting shell and a second mounting shell, a side of the first mounting shell being provided with a guide rod, and an outer sleeve of the guide rod being provided with a first spring, and an outer movable sleeve of the guide rod being provided with two groups of linkage plates, and push plates being installed at the ends of the two groups of linkage plates, both ends of the second mounting shell being rotatably connected to a cleaning assembly, and the side of the second mounting shell being rotatably connected to a forward and reverse threaded rod, and the outer threads of the forward and reverse threaded rod being connected to two groups of locking blocks, the two groups of locking blocks being symmetrically arranged, a knob being provided at one end of the forward and reverse threaded rod, and the forward and reverse threaded rod and the two groups of cleaning assemblies being transmission connected by a pulley assembly.

[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 serve as a simple storage. 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. In view of 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 joint between the first mounting shell and the second mounting shell is configured as a chimeric joint to improve the sealing performance, and a first sealing ring and a second sealing ring are provided at the 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 providing 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 component.

[0012] The present invention is further configured such that the two groups of locking blocks are movably mounted on the outer wall of the second mounting shell by providing 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 limiting 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 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 driving the forward and reverse threaded rods to rotate can drive the cleaning assembly 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 mounted inside the sleeve by arranging multiple sets of second springs, and a limiting groove is provided on the inner wall of the sleeve.

[0019] Preferably, by providing a carrying ring and multiple sets of second springs, the flexible cleaning brush can be retracted 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, and an outer convex ring is provided on the outside of the flexible cleaning brush, and the outer convex ring is fitted to the side of the carrying ring, and the outer convex ring matches the limiting groove.

[0021] Preferably, a flexible cleaning brush is provided to wipe and clean the objective lens and eyepiece of the total station, and the flexible cleaning brush is embedded in the sleeve through the outer convex ring, and the embedding 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 provided on the outside of the first installation shell, and a second protective shell is provided on the outside of the second installation shell.

[0023] Preferably, the first protective shell and the second protective shell are provided to protect the first installation shell and the second installation shell.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. The present invention can wrap and protect the total station 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 serve as a simple storage function. 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. In view of the complex environment of the construction site, the total station is protected and the risk of damage to the total station by external factors is reduced.

[0026] 2. The present invention can simply clean the objective lens and eyepiece of the total station by arranging a cleaning assembly. The first mounting shell and the second mounting shell are fixed by arranging a linkage plate and a locking block. Rotating the positive and negative threaded rods will drive the two sets of locking blocks to approach each other and press the linkage plate to achieve the effect of closing and locking the first mounting shell and the second mounting shell. The positive and negative threaded rods will continue to rotate, so that the locking block will continue to push the linkage plate to move. Since the objective lens and eyepiece of the total station are often in a sunken state, the linkage plate is designed to continue to move to push the two sets of cleaning assemblies to actively adhere to the objective lens and eyepiece. While the positive and negative threaded rods rotate, they will drive the cleaning assembly rotating rod through the pulley assembly. Therefore, when the cleaning assembly starts to adhere to the objective lens and eyepiece, the cleaning assembly will rotate synchronously to achieve wiping and cleaning of the objective lens and eyepiece.

[0043] In the above embodiment, 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.

[0045] In the above embodiment, 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 that match the linkage plate 6. By opening an engaging groove that matches 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 push the linkage plate 6 to move in the horizontal direction.

[0046] In the above embodiment, 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 forward and reverse threaded rod 12 can be driven to rotate to drive the cleaning assembly 16 to rotate, so that the cleaning assembly 16 can rotate to wipe the objective lens and eyepiece of the total station 2.

[0047] In the above embodiment, please refer to Figure 8 The interior of the sleeve 1601 is movably mounted with a carrying ring 1603 by setting multiple sets of second springs 1602, and a limiting groove 1604 is provided 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.

[0048] In the above embodiment, please refer to Figure 8A flexible cleaning brush 1605 is movably installed inside the sleeve 1601, and an outer convex ring 1606 is provided on the outside of the flexible cleaning brush 1605, and the outer convex ring 1606 is attached to the side of the carrying ring 1603, and the outer convex ring 1606 matches the limiting groove 1604. By setting the flexible cleaning brush 1605, the objective lens and eyepiece of the total station 2 can be wiped and cleaned, and the flexible cleaning brush 1605 is embedded in the sleeve 1601 through the outer convex ring 1606, and the embedding between the two is precise, so that the sleeve 1601 can better drive the flexible cleaning brush 1605 to rotate.

[0049] In the above embodiment, please refer to Figure 1 A first protective shell 18 is provided on the outside of the first mounting shell 3, and a second protective shell 19 is provided on the outside of the second mounting shell 11. The first protective shell 18 and the second protective shell 19 can protect the first mounting shell 3 and the second mounting shell 11.

[0050] During the specific operation of the present invention: when the construction worker uses the total station 2 to measure the engineering data and needs to store the total station 2, the construction worker first manually pushes the first mounting shell 3 and the second mounting shell 11 to close. At this time, the two groups of cleaning components 16 are in the state of the objective lens and eyepiece of the principle total station 2, and the driving knob 15 is rotated. The rotation of the knob 15 will drive the forward and reverse threaded rods 12 to rotate, and the forward and reverse threaded rods 12 drive the two groups of cleaning components 16 to rotate through the two groups of pulley assemblies 17. At this time, since the cleaning component 16 is not in contact with the objective lens and eyepiece of the total station 2, the cleaning component 16 will not clean the objective lens and eyepiece of the total station 2, and the rotation of the forward and reverse threaded rods 12 will drive the two groups of locking blocks 13 to slide close to each other along the second limit assembly 14, and the two groups of locking blocks 13 approach each other until they are in contact with the two corresponding linkage plates 6. Figure 9At this time, the two sets of locking blocks 13 will compress and lock the linkage plate 6, but the forward and reverse threaded rods 12 will continue to rotate, so that the two sets of locking blocks 13 will push the two sets of linkage plates 6 closer to each other. The two sets of linkage plates 6 approaching each other will compress the first spring 5, and the two sets of linkage plates 6 approaching each other will also synchronously drive the pushing plate 8 to squeeze the cleaning assembly 16, so that the two sets of cleaning assemblies 16 are retracted into the interior of the second mounting shell 11, and then the two sets of cleaning assemblies 16 will actively fit the objective lens and eyepiece of the total station 2 in the recessed state. The flexible cleaning brush 1605 of the cleaning assembly 16 is a flexible cleaning tool. When the flexible cleaning brush 1605 is in contact with the objective lens When the flexible cleaning brush 1605 is cleaned by the eyepiece, the flexible cleaning brush 1605 can still continue to move a certain distance. When the flexible cleaning brush 1605 is squeezed by the pushing plate 8, the flexible cleaning brush 1605 pushes the carrying ring 1603 to move through the flexible cleaning brush 1605. The carrying ring 1603 will compress the multiple groups of second springs 1602, and the cleaning component 16 will also rotate synchronously due to the drive of the pulley assembly 17. Then the sleeve 1601 will drive the flexible cleaning brush 1605 to rotate through 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.

[0051] The above are the steps after the total station 2 is used. Similarly, every time the construction worker needs to use the total station 2, he needs to first open the tripod 1 and adjust the installation angle of the tripod 1. According to the steps, turn the knob 15. The two sets of cleaning components 16 will clean the objective lens and eyepiece of the total station 2, and then move away from each other so that the worker 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 work.

The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention.
