Description

Technical Field

[0001] This utility model relates to the field of land surveying technology, specifically a land engineering surveying device. Background Technology

[0002] Land surveying is the process of obtaining data on the natural attributes, engineering characteristics, and environment of land through technical means, providing a scientific basis for land development, planning, design, and construction. During surveying, it is necessary to use land engineering surveying and sampling devices to obtain soil samples to study the geological environment of a specific area.

[0003] Existing land survey gasoline-powered sampling devices generally consist of a gasoline engine, a drill rod, and a drill bit. During use, the user holds the gasoline engine, places the drill bit in the sampling area, and then starts the gasoline engine to rotate the drill rod and drill bit to penetrate the soil for sampling. However, if the drill bit encounters rocks or other hard debris during sampling, it can easily stop abruptly due to the obstruction. This causes the torque applied by the gasoline engine to the drill rod and drill bit to be instantly reversed back to the gasoline engine, resulting in violent twisting of the engine body. This can easily cause sprains to the user's arms and lead to safety accidents. Therefore, a land engineering survey device is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a land engineering surveying device with the advantage of high safety. It solves the problem that in existing gasoline-powered land surveying sampling devices, when encountering stones or other hard debris during sampling, the drill bit can easily stop suddenly due to obstruction by the stones or other hard debris. This causes the torque acting on the drill rod and drill bit to be instantly reversed and transmitted to the gasoline engine, resulting in violent twisting of the gasoline engine body, which can easily cause sprains to the user's arms and lead to safety accidents.

[0005] To achieve the aforementioned goal of high safety in use, this utility model provides the following technical solution: a land engineering surveying device, comprising a gasoline engine and a support frame, wherein a limiting support mechanism is provided between the gasoline engine and the support frame. The limiting support mechanism includes a connecting plate fixedly installed on the lower surface of the gasoline engine, a limiting post fixedly installed on the upper surface of the support frame, a limiting sleeve fitted onto the surface of the limiting post fixedly installed on the surface of the connecting plate, a moving wheel fixedly installed on the lower surface of the support frame, a U-shaped frame slidably installed through the support frame, a support plate fixedly installed at the bottom of the U-shaped frame, a limiting rod fixedly installed on the lower surface of the support plate, a threaded rod threadedly connected to the surface of the U-shaped frame, a storage mechanism provided on the limiting post, a drill rod fixedly installed at the output end of the gasoline engine, and a drill bit fixedly installed at the end of the drill rod away from the gasoline engine.

[0006] Furthermore, two support rods are fixedly installed on the upper surface of the connecting plate, and a handrail is fixedly installed on the top of the support rod.

[0007] Furthermore, there are two of each of the limiting posts and limiting sleeves, which are distributed on both sides of the connecting plate. There are multiple of each of the moving wheels and limiting rods. The threaded rod is located above the support frame, and the limiting rod is located below the support frame.

[0008] Furthermore, the limiting post is composed of three first arc-shaped plates and three second arc-shaped plates. The three first arc-shaped plates are fixedly installed on the surface of the support frame in a ring shape, and the three second arc-shaped plates are distributed between two adjacent first arc-shaped plates.

[0009] Furthermore, the storage mechanism includes threaded sleeves fixedly installed inside the three first arc-shaped plates, a limiting plate fixedly installed on the top of the second arc-shaped plate, a fixing rod rotatably installed on the surface of the limiting plate, the fixing rod passing through the threaded sleeves, and a threaded section on the surface of the fixing rod, the threaded section being away from the limiting plate.

[0010] Furthermore, each of the two adjacent first arc-shaped plates has a limiting groove on its opposite side surface, and each of the second arc-shaped plates has a limiting slider that is fixedly installed on its opposite side surface and inserted into the limiting groove.

[0011] Compared with the prior art, the present invention provides a land engineering surveying device, which has the following beneficial effects: 1. This land engineering surveying device, through the setting of limiting posts and limiting sleeves, can limit the gasoline engine, preventing the gasoline engine body from twisting and injuring the user's arm. Through the cooperation of the U-shaped frame, support plate and limiting rod, after the sampling device is moved to the appropriate position, the U-shaped frame is rotated by rotating the threaded rod, which drives the support plate and limiting rod to move downwards, so that the limiting rod inserts into the ground, which can fix the sampling device on the ground, providing stable support for subsequent sampling, preventing the sampling device from moving during the sampling process, thus greatly reducing the risk of twisting the user's arm and improving the safety of the sampling device.

[0012] 2. This land engineering surveying device, by setting up a storage mechanism, allows the fixed rod to be rotated to disengage the threaded section from the threaded sleeve when the sampling device is not needed. Then, the second arc-shaped plate moves along the limiting groove towards the first arc-shaped plate, so that the first and second arc-shaped plates are brought together to store the limiting column. This helps to reduce the space occupied by the sampling device and facilitates the storage and transportation of the sampling device. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1-4 This embodiment of a land engineering surveying device includes a gasoline engine 1 and a support frame 2. A limiting support mechanism 3 is provided between the gasoline engine 1 and the support frame 2. The limiting support mechanism 3 includes a connecting plate 31 fixedly installed on the lower surface of the gasoline engine 1, a limiting post 32 fixedly installed on the upper surface of the support frame 2, a limiting sleeve 33 fixedly installed on the surface of the connecting plate 31 and fitted onto the surface of the limiting post 32, a movable wheel 34 fixedly installed on the lower surface of the support frame 2, and a U-shaped frame 35 slidably installed through the support frame 2. Figure 4 A support plate 36 is fixedly installed at the bottom of the U-shaped frame 35. A limit rod 37 is fixedly installed on the lower surface of the support plate 36. A threaded rod 38 is threadedly connected to the surface of the U-shaped frame 35. A storage mechanism 4 is provided on the limit post 32. A drill rod 5 is fixedly installed at the output end of the gasoline engine 1. A drill bit 6 is fixedly installed at the end of the drill rod 5 away from the gasoline engine 1.

[0017] In this embodiment, two support rods 7 are fixedly installed on the upper surface of the connecting plate 31, and a handrail 8 is fixedly installed on the top of the support rod 7 to facilitate the user to move the sampling device downwards during use.

[0018] In this embodiment, there are two limiting posts 32 and two limiting sleeves 33, which are distributed on both sides of the connecting plate 31. There are multiple moving wheels 34 and multiple limiting rods 37. The threaded rod 38 is located above the support frame 2, and the limiting rod 37 is located below the support frame 2.

[0019] In this embodiment, the limiting post 32 is composed of three first arc-shaped plates 321 and three second arc-shaped plates 322. The three first arc-shaped plates 321 are fixedly installed on the surface of the support frame 2 in a ring shape, and the three second arc-shaped plates 322 are distributed between two adjacent first arc-shaped plates 321.

[0020] In this embodiment, the storage mechanism 4 includes threaded sleeves 41 fixedly installed inside the three first arc-shaped plates 321, and a limiting plate 42 fixedly installed on the top of the second arc-shaped plate 322. A fixing rod 43 is rotatably installed on the surface of the limiting plate 42. The fixing rod 43 passes through the threaded sleeves 41, and the surface of the fixing rod 43 is provided with a threaded section, which is away from the limiting plate 42.

[0021] In this embodiment, a limiting groove 44 is provided on the opposite side surface of two adjacent first arc plates 321, and a limiting slider 45 is fixedly installed on the opposite side surface of the second arc plate 322, which is inserted into the limiting groove 44. By setting the limiting groove 44 and the limiting slider 45, the separation between the first arc plate 321 and the second arc plate 322 can be avoided.

[0022] The working principle of the above embodiments is as follows: The sampling device can be moved to the sampling area by the moving wheel 34. After arriving at the sampling area, the user rotates the threaded rod 38 to raise it to its highest position, and then presses down the U-shaped frame 35, causing the support plate 36 and the limiting rod 37 to move downwards until the limiting rod 37 is inserted into the ground. During sampling, the user holds the handrail 8 and starts the gasoline engine 1. The output end of the gasoline engine 1 drives the fixed drill rod 5 and drill bit 6 to rotate. The user controls the position of the gasoline engine 1 by holding the handrail 8, so that the rotating drill bit 6 penetrates into the soil for sampling. The cooperation of the limiting post 32 and the limiting sleeve 33 allows the sampling device to move along the limiting post 32. By inserting the limiting rod 37 into the ground, the support frame 2 can be limited and fixed. The limiting post 32 can be limited by the support frame 2, thereby limiting the entire sampling device and preventing the sampling device from twisting during sampling. When the device is not needed, the user can rotate the fixing rod 43 to disengage the threaded section of the fixing rod 43 from the threaded sleeve 41, so that the second arc plate 322 can move along the limiting slide groove 44 towards the first arc plate 321, thereby storing the limiting post 32. After sampling is completed, the threaded rod 38 is rotated. When the bottom of the threaded rod 38 contacts the support frame 2, the threaded rod 38 is rotated again, so that the threaded rod 38 can drive the U-shaped frame 35 to move upward. With the support of the moving wheel 34, the support plate 36 and the limiting rod 37 can be moved upward, thereby pulling the limiting rod 37 out of the soil.
