Description

Technical Field

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

[0002] Engineering surveying refers to a series of technical tasks carried out for various engineering projects, aiming to collect, analyze and study data on geology, hydrology, geophysics, environment, transportation, etc., and to provide scientific and reliable basic data for engineering design and construction.

[0003] In current engineering surveying operations, operators often need to use drilling rigs and drill rods to drill and sample soil layers in designated construction areas. By analyzing the soil structure samples, subsequent construction plans can be formulated. However, the sampling devices currently used in engineering surveying have the following shortcomings in actual use: drilling rigs and multiple drill rods are mostly of separate structure. When placing the drilling rigs and drill rods at designated locations or during transportation, they are often directly scattered on the ground, in the vehicle, or in storage containers. The entire operation process is prone to contact wear, impact damage, and rolling problems caused by stress on the drilling rigs and drill rods. At the same time, the scattered state of the drilling rigs and drill rods makes it inconvenient for operators to handle and transport them, thus reducing the portability and stability of actual engineering surveying sampling.

[0004] In view of this, it is particularly important to design and manufacture a sampling device that is easy to carry and use as a whole, and can reduce the injury and risk during handling and transportation, for application in engineering surveying. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing engineering survey sampling devices, which are inconvenient for the fixed placement and transportation of drilling rigs and drill rods, and are prone to contact wear, impact damage, and rolling under stress during actual handling and transportation. Therefore, a portable engineering survey sampling device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable engineering survey sampling device includes a drilling rig, a fixed head mounted on the drilling rig, and multiple drill rods disposed on the outside of the drilling rig. The drilling rig is equipped with a housing, the inside of which is filled with a foam filling layer that encloses the drilling rig. A jacking slot for accommodating the drilling rig is formed in the middle of the foam filling layer. A rod release slot for storing multiple drill rods is symmetrically formed on both sides of the jacking slot inside the foam filling layer. A carriage mechanism for assisting the drilling rig in its downward drilling operation is provided between the housing and the drilling rig.

[0008] As a further description of the above technical solution:

[0009] The slide mechanism includes two guide slide rods symmetrically rotated and installed at the front end of the housing and located on the left and right sides of the drilling machine, and guide slide cylinders fixed on the left and right sides of the drilling machine and matching the guide slide rods.

[0010] As a further description of the above technical solution:

[0011] A handle is integrally fixed to the outside of the guide slide.

[0012] As a further description of the above technical solution:

[0013] The drilling rig is equipped with an external electrical control switch for controlling its operation.

[0014] As a further description of the above technical solution:

[0015] The upper end of the box is open, and a box cover is rotatably installed on the upper end of the box to cover the box.

[0016] As a further description of the above technical solution:

[0017] A handle is integrally and fixedly connected to the middle of the rear end of the box.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] In this invention, the original sampling device has been scientifically and rationally improved. A box, a cover, a foam filling layer, a guide slide, a guide sleeve, and a handle are installed on the outside of the drilling rig and multiple drill rods. The drilling rig can be rotatably placed in the box through the guide slide and guide sleeve, while multiple drill rods are stored in the rod placement grooves of the foam filling layer. During actual drilling and sampling operations, the cover is opened, the drilling rig is rotated from the box to a vertical position, and the drill rods can be installed below the fixed head of the drilling rig. Then, the drill rods are drilled vertically downwards into the soil layer. This structure can centrally store the drilling rig and drill rods in the box, which facilitates the handling, carrying, transportation, and drilling and sampling operations of the entire sampling device. It effectively reduces the occurrence of contact wear, impact damage, and rolling under stress during the handling or transportation of the sampling device, thereby improving the portability and stability of the sampling device.
