Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, and in particular to a surveying device for earthwork filling projects. Background Technology

[0002] Earthwork filling is a fundamental part of all types of construction projects and plays a crucial role in project quality. During earthwork filling, accurately grasping parameters such as the location, thickness, and compaction degree of the filling materials is a core requirement to ensure that the project meets design standards and possesses stability and load-bearing capacity. Traditional surveying equipment, such as levels and theodolites, suffers from limited measurement accuracy, cumbersome operation, and low efficiency, making it difficult to meet the needs of large-scale earthwork filling projects in complex terrains. With the vigorous development of the construction industry, the scale and complexity of earthwork filling projects are constantly increasing, creating an urgent need for advanced, efficient, and accurate surveying equipment to improve project quality and construction progress. New types of surveying equipment for earthwork filling projects have emerged to meet this need.

[0003] In the existing technology, when using a rangefinder, the rangefinder is fixed on a mounting plate. When multiple directions need to be measured, the bracket needs to be twisted and moved, which is time-consuming and laborious.

[0004] To address the aforementioned issues, an existing patent (publication number: CN214368701U) proposes a measuring device for earthwork filling projects. The device includes a support frame comprising a placement platform and several telescopic rods hinged to the placement platform. The placement platform is equipped with an adjustment component that allows for adjustment of the orientation of the handheld rangefinder. The adjustment component includes a mounting plate rotatably connected to the placement platform, and the handheld rangefinder is placed on the mounting plate. This application offers the advantage of facilitating measurements in multiple directions.

[0005] To address the aforementioned issues, existing patents offer solutions. However, current 3D scanners for earthwork filling surveys typically require the use of devices such as mobile phones and tablets for auxiliary mapping. When mounting mobile phones and computers onto the outside of the 3D scanner, fixed brackets or quick-release brackets are usually used. Fixed brackets are inconvenient to assemble and disassemble and difficult to replace, while quick-release brackets are only suitable for one or two types of equipment, resulting in low flexibility. Furthermore, they cannot provide further protection for the auxiliary equipment to prevent it from falling off the bracket and being damaged due to the complex construction site environment causing personnel to trip and unconsciously grasp the 3D scanner.

[0006] Therefore, a measuring device for earthwork filling projects is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a measuring device for earthwork filling projects, which can solve the problems of poor ease of disassembly and assembly, low adaptability, and limited protection of existing devices.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a measuring device for earthwork filling engineering, including a three-dimensional scanner, a convenient fixing mechanism movably connected to the top of the three-dimensional scanner, a limit protection mechanism movably connected to the inner side of the convenient fixing mechanism, and a debugging handheld device movably connected to the inner side of the convenient fixing mechanism.

[0009] The convenient fixing mechanism includes a support base, a storage slot, a positioning plate, and a clamping assembly. The support base is fixedly connected to the top of the 3D scanner, the storage slot is located on the right side of the top of the support base, the positioning plate is fixedly connected to the inside of the storage slot, and the clamping assembly is movably connected to the inside of the storage slot.

[0010] Preferably, the limiting protection mechanism includes a limiting baffle, a first telescopic rod, a tension spring, a positioning pin, and a positioning slot.

[0011] Preferably, the limiting baffle is movably connected to the right side of the clamping assembly, the first telescopic rod is fixedly connected to the right side of the limiting baffle, the tension spring is fixedly connected to the outside of the first telescopic rod, and the positioning pin is fixedly connected to the outside of the first telescopic rod.

[0012] Preferably, the positioning pin is movably connected to the inner side of the limiting baffle, the positioning pin is movably connected to the inner side of the positioning slot, and the positioning slot is opened on the inner side of the clamping assembly.

[0013] Preferably, the clamping assembly includes a second telescopic rod, a compression spring, a clamping rod, and a linkage lever.

[0014] Preferably, the second telescopic rod is fixedly connected to the front and rear sides of the inner side of the storage slot, the compression spring is fixedly connected to the outer side of the second telescopic rod, the clamping rod is fixedly connected to the outer side of the second telescopic rod, the clamping rod is slidably connected to the inner side of the storage slot, the linkage lever is fixedly connected to the outer side of the clamping rod, the linkage lever is disposed on the top of the support base, the positioning slot is opened on the inner side of the clamping rod, and the limiting baffle is slidably connected to the right side of the clamping rod.

[0015] Preferably, an elastic clamping pad is fixedly connected to the outer side of the clamping rod.

[0016] Preferably, a dust cover is movably connected to the right side of the 3D scanner.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a convenient fixing mechanism, allows for quick fixing by moving the clamping rod by simply opening the lever with one hand, compressing the second telescopic rod and the compression spring to store elastic potential energy, and then releasing the lever after inserting the debugging handheld device. Compared to fixed brackets, this installation method requires no complicated operations; it can be disassembled simply by releasing the lever, and installation only requires a simple push-in action, greatly improving the convenience of installation and disassembly and facilitating replacement. Compared to quick-release brackets, it relies on the elasticity of the second telescopic rod and the compression spring to adapt to different models of debugging handheld devices, and can automatically adjust the clamping force according to the device size, providing greater flexibility. It overcomes the limitation of quick-release brackets being suitable for only one or two types of equipment, meeting the loading requirements of different auxiliary surveying equipment during earthwork filling surveying.

[0019] 2. This application, by setting up a limit protection mechanism, allows the positioning pin to disengage from the positioning slot, the extension rod and tension spring to accumulate elastic potential energy, and then the limit baffle to be moved to the designated position and the positioning pin to be released. The rebound completes the limit, and finally the limit baffles on both sides lock the handheld device. It effectively solves the problem of auxiliary equipment protection. In complex construction sites, when personnel trip and unconsciously grip the 3D scanner, the auxiliary equipment is prone to falling off the support. However, this design, through the positioning pin and limit baffles, stabilizes the handheld device from both sides, greatly reducing the risk of the equipment falling off the support due to accidental movement. It provides strong protection for the safe use of auxiliary equipment in complex environments and avoids losses caused by equipment damage. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A measuring device for earthwork filling projects includes a three-dimensional scanner 1, a convenient fixing mechanism 2 movably connected to the top of the three-dimensional scanner 1, a limit protection mechanism 3 movably connected to the inner side of the convenient fixing mechanism 2, and a debugging handheld device 4 movably connected to the inner side of the convenient fixing mechanism 2.

[0029] The convenient fixing mechanism 2 includes a support base 21, a storage slot 22, a positioning plate 23, and a clamping assembly 24. The support base 21 is fixedly connected to the top of the 3D scanner 1. The storage slot 22 is opened on the right side of the top of the support base 21. The positioning plate 23 is fixedly connected to the inside of the storage slot 22. The clamping assembly 24 is movably connected to the inside of the storage slot 22.

[0030] In this embodiment: the support base 21 can support and fix the debugging handheld device 4, the storage slot 22 can limit the debugging handheld device 4, the positioning plate 23 can position the debugging handheld device 4, and the clamping component 24 can fix the debugging handheld device 4 to the inside of the storage slot 22, thus completing the quick installation and adapting to different models of debugging handheld devices 4 within a certain range.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the limiting protection mechanism 3 includes a limiting baffle 31, a first telescopic rod 32, a tension spring 33, a positioning pin 34, and a positioning slot 35.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the limiting baffle 31 is movably connected to the right side of the clamping assembly 24, the first telescopic rod 32 is fixedly connected to the right side of the limiting baffle 31, the tension spring 33 is fixedly connected to the outside of the first telescopic rod 32, and the positioning pin 34 is fixedly connected to the outside of the first telescopic rod 32.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown, the positioning pin 34 is movably connected to the inner side of the limiting baffle 31, and the positioning pin 34 is movably connected to the inner side of the positioning slot 35, which is located inside the clamping assembly 24.

[0034] In this embodiment: by pulling the positioning pin 34, it is disengaged from the positioning slot 35 of the clamping rod 24c. The first telescopic rod 32 and the tension spring 33 are stretched to accumulate elastic potential energy, and the limiting baffle 31 is pulled to the edge of the debugging handheld device 4. After holding the limiting baffle 31, the positioning pin 34 is released, the first telescopic rod 32 and the tension spring 33 rebound, and the positioning pin 34 is locked back into the positioning slot 35 to complete the limiting. The two sets of limiting baffles 31 are locked on both sides of the debugging handheld device 4 to complete the protective installation. This can prevent the debugging handheld device 4 from falling off the bracket and being damaged due to the complex road surface of the construction site and the personnel tripping and unconsciously gripping the 3D scanner 1.

[0035] Specifically, such as Figure 3 , Figure 4 As shown, the clamping assembly 24 includes a second telescopic rod 24a, a compression spring 24b, a clamping rod 24c, and a linkage lever 24d.

[0036] Specifically, such as Figure 3 , Figure 4 As shown, the second telescopic rod 24a is fixedly connected to the front and rear sides of the inner side of the storage slot 22, the compression spring 24b is fixedly connected to the outer side of the second telescopic rod 24a, the clamping rod 24c is fixedly connected to the outer side of the second telescopic rod 24a, the clamping rod 24c is slidably connected to the inner side of the storage slot 22, the linkage lever 24d is fixedly connected to the outer side of the clamping rod 24c, the linkage lever 24d is set on the top of the support base 21, the positioning slot 35 is opened on the inner side of the clamping rod 24c, and the limiting baffle 31 is slidably connected to the right side of the clamping rod 24c.

[0037] In this embodiment: There are two linkage levers 24d on the top of the support base 21. The worker can use one hand to push them open, causing them to move to both sides. This moves the clamping rods 24c at the bottom of the linkage levers 24d towards the inner walls of both sides of the storage slot 22. At this time, the second telescopic rod 24a and the outer compression spring 24b between the clamping rods 24c and the inner wall of the storage slot 22 retract and compress, storing elastic potential energy. Then, the worker takes out the debugging handheld device 4 with the other hand and pushes it horizontally into the center of the groove of the positioning plate 23. After releasing the levers, the second telescopic rod 24a and the compression spring 24b release their elastic potential energy and rebound, causing the clamping rods 24c on both sides to quickly clamp the two sides of the debugging handheld device 4, achieving quick fixation. This installation method is compatible with different models of debugging handheld devices 4, making it easy to install, disassemble, and recycle.

[0038] Specifically, such as Figure 5 As shown, an elastic clamping pad 5 is fixedly connected to the outer side of the clamping rod 24c.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, a dust cover 6 is movably connected to the right side of the 3D scanner 1.

[0040] In this embodiment: the elastic clamping pad 5 increases the clamping effect when the clamping rod 24c contacts the debugging handheld device 4, and adapts to different shell shapes of the debugging handheld device 4. The dust cover 6 can prevent dust from entering the wiring port of the 3D scanner 1.

[0041] Working Principle: During earthwork filling surveying, workers typically use a handheld 3D scanner 1, along with a mobile phone, tablet, or other handheld device 4 for auxiliary measurement. The support base 21 has two linkage levers 24d on its top. The worker uses one hand to move the levers to the sides, causing the clamping rods 24c at the bottom of the linkage levers 24d to move towards the inner walls of the storage groove 22. At this time, the clamping rods 24c, along with the second telescopic rod 24a and its outer compression spring 24b on the inner wall of the storage groove 22, contract and compress, storing elastic potential energy. Then, the worker uses their other hand to take out the handheld device 4 and push it horizontally into the center of the groove in the positioning plate 23. After releasing the levers, the second telescopic rod 24a and compression spring 24b release their elastic potential energy and quickly rebound, causing the clamping rods 24c on both sides to quickly clamp the handheld device 4, achieving quick fixation. This installation method is suitable for... Different models of handheld debugging devices 4 are available, and the devices are easy to install, disassemble, and retrieve. After the clamping rod 24c is used to fix the handheld debugging device 4, the positioning pin 34 is pulled to disengage it from the positioning slot 35 inside the clamping rod 24c. At the same time, the first telescopic rod 32 between the positioning pin 34 and the limit baffle 31 and the tension spring 33 on its outer side are stretched to accumulate elastic potential energy. Then, the limit baffle 31 is pulled to one side of the edge of the handheld debugging device 4. The limit baffle 31 is held and the positioning pin 34 is released. The first telescopic rod 32 and the tension spring 33 rebound, and the positioning pin 34 quickly snaps into the positioning slot 35 to complete the limit. The two sets of limit baffles 31 are respectively clamped on both sides of the handheld debugging device 4 to complete the protective installation. This effectively avoids the situation where the handheld debugging device 4 falls off the bracket and is damaged due to the complex road surface of the construction site and the unconscious gripping of the 3D scanner 1 when people trip.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
