DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3The utility model provides a geotechnical engineering geophysical prospecting device, including a mounting frame 101, a base 105 is fixed at the bottom of the mounting frame 101, a lifting plate 102 is connected to the mounting frame 101 through a lifting assembly to be lifted and pulled, a drill rod 103 is rotatably connected to the lifting plate 102, a driving motor 104 for driving the drill rod 103 is installed at the upper end of the lifting plate 102, and a plurality of anti-swing support components for supporting the drill rod 103 against sway during work are arranged on the base 105, and the anti-swing support components include a mounting seat 201, a pushing component for pushing the mounting seat 201 is arranged on the base 105, a support plate 202 is detachably connected to one side of the mounting seat 201 through the mounting assembly, and an arc groove 203 for abutting against the outer side of the drill rod 103 is opened on one side of the support plate 202;

[0019] It should be noted here that when using a geophysical exploration device to carry out geophysical exploration operations in geotechnical engineering, multiple sets of anti-sway support components cooperate with each other to provide auxiliary support for the descending and rotating drill rod 103, thereby reducing the amplitude of the violent swing of the drill rod 103 caused by the long length of the drill rod 103, making it easier for the device to carry out geotechnical engineering geophysical exploration operations more stably, efficiently and safely.

[0020] The anti-sway support components are arranged in a circular array on the base 105;

[0021] It should be noted here that the support effect is improved by providing multiple anti-sway support components in an annular array.

[0022] The upper end of the support plate 202 is provided with an inclined surface 3; the pushing assembly includes a plurality of sleeves 401 fixed to the inner side of the base 105, each sleeve 401 is slidably connected with a slide rod 402, one end of the slide rod 402 is fixed to the mounting seat 201, and a spring 403 is sleeved on the outer side of each sleeve 401, and the two ends of the spring 403 are respectively set against the base 105 and the mounting seat 201;

[0023] It should be noted here that: during the downward movement of the drill rod 103, the front end of the drill rod 103 abuts against the inclined surface 3 on the support plate 202 on each anti-sway support assembly, pushing each support plate 202 to move away from each other under force. During the movement of each support plate 202 away from each other, the mounting seat 201 pushes each sliding rod 402 to slide on each casing 401 respectively, causing the spring 403 to deform under force and generate elastic force. As the drill rod 103 continues to move downward, under the pushing action of the elastic force of each spring 403, the arc groove 203 on one side of the support plate 202 on the mounting seat 201 abuts against the outer side of the drill rod 103.

[0024] The mounting assembly includes a threaded hole 501 provided on the mounting seat 201 and the support plate 202, a bolt 502 is threadedly engaged with the threaded hole 501, and a positioning assembly for positioning and guiding during the installation process is provided between the mounting seat 201 and the support plate 202;

[0025] It should be noted here that: through the cooperation between the bolts 502 and the threaded holes 501 , it is convenient to replace and install different support plates 202 on the mounting seat 201 .

[0026] The positioning assembly includes a plurality of positioning holes 601 formed on the mounting seat 201, and a plurality of positioning pins 602 matching the positioning holes 601 are fixed to one side of the support plate 202;

[0027] It should be noted here that the support plate 202 is positioned during the installation process through a plurality of positioning holes 601 and positioning pins 602 .

[0028] Working principle: When using the geophysical prospecting device to perform geophysical prospecting operations in geotechnical engineering, the entire device is moved to a designated position. After the movement is completed, the lifting plate 102 is driven to move downward by the lifting assembly. During the downward movement of the lifting plate 102, the drill rod 103 is driven to rotate by the driving motor 104. During the downward and rotating process of the drill rod 103, the rock and soil at the designated position are transported out to assist subsequent geophysical prospecting operations;

[0029] During the downward movement of the drill rod 103, the front end of the drill rod 103 abuts against the inclined surface 3 on the support plate 202 on each anti-sway support assembly, pushing each support plate 202 to move away from each other under force. During the movement of each support plate 202 away from each other, the mounting seat 201 pushes each slide bar 402 to slide on each casing 401 respectively, causing the spring 403 to deform under force to generate elastic force. As the drill rod 103 continues to move downward, under the pushing action of the elastic force of each spring 403, the arc groove 203 on one side of the support plate 202 on the mounting seat 201 abuts against the outer side of the drill rod 103, providing auxiliary support for the descending and rotating drill rod 103, reducing the amplitude of the violent swing of the drill rod 103 caused by the long use length of the drill rod 103, and facilitating the device to perform geotechnical engineering prospecting and exploration operations more stably, efficiently and safely.
