Description

Technical Field

[0001] The utility model relates to the technical field of engineering geology foundation detection, and particularly relates to a surveying and mapping device for engineering geology foundation detection with an anti-tipping effect. Background Technique

[0002] The surveying and mapping device for engineering geology foundation detection is a tool used to evaluate and analyze soil and infrastructure foundation conditions, and is widely used in fields such as construction engineering, underground engineering, and traffic engineering. Total stations or laser rangefinders are usually used to detect engineering geology foundations to ensure the safety and reliability of projects.

[0003] After retrieval, the Chinese patent "An auxiliary device for building foundation detection" with the authorization announcement number "CN221052694U" realizes the stable support of the surveying and mapping device and the base through the support rod, support feet, motor, gear one, gear two, clamping block and supporting nail, improving the accuracy during each foundation detection.

[0004] In the above application, four groups of supporting nails need to be sequentially embedded into the foundation, and the length of the support rod is limited. Since there are often more construction waste soils at the foundation before construction, the foundation is mostly uneven, which easily causes the four groups of supporting nails to be difficult to be evenly embedded into the foundation, thus affecting the support stability of the detection equipment.

[0005] Therefore, a surveying and mapping device for engineering geology foundation detection with an anti-tipping effect is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a surveying and mapping device for engineering geology foundation detection with an anti-tipping effect to solve the above problems, and improve the problem that four groups of supporting nails are difficult to be evenly embedded into the foundation, thus affecting the support stability of the detection equipment.

[0007] The present utility model achieves the above object through the following technical solutions. A surveying and mapping device for engineering geology foundation detection with an anti-tipping effect includes: a mounting plate, on the top of which a laser surveying instrument is provided; a stabilizing mechanism, which is arranged at the bottom end of the mounting plate; wherein, the stabilizing mechanism includes sliding frames annularly distributed and hinged to the inner side of the mounting plate, the inner wall of the sliding frame is slidably connected with a sliding plate, the lower end of the surface of the sliding plate is hinged with a movable frame, the inner wall of the movable frame is slidably connected with a movable block, the bottom of the movable block is fixedly connected with ground inserting nails distributed in equal columns, the inner wall of the sliding frame is slidably connected with a fixed block, the front end of the sliding plate is fixedly connected with positioning blocks distributed in equal columns, the front end of the fixed block is fixedly connected with an elastic sheet, and the front end of the elastic sheet is fixedly connected to the inner wall of the sliding frame. Through the sliding frame, the sliding plate, the elastic sheet, the positioning block and the fixed block, the height of the movable block is adjusted and the adjusted sliding plate is locked, so that the three groups of ground inserting nails are evenly embedded into the foundation. Compared with the existing method that it is difficult to adjust the height of each support rod according to the uneven ground conditions, this method is convenient to adjust the height of each group of ground inserting nails according to the uneven ground, so that the three groups of ground inserting nails are evenly embedded into the foundation, thereby ensuring the stable support of the surveying and mapping device.

[0008] Preferably, the bottom end of the mounting plate is fixedly connected with an air delivery frame, the bottom end of the air delivery frame is communicated with one side of the inner wall of the movable frame, the bottom end of the mounting plate is fixedly connected with an air pump, and the bottom end of the air pump is communicated with the top end of the air delivery frame. Through the air pump and the air delivery frame, the gas is delivered into the movable frame, so that the three groups of ground inserting nails are synchronously embedded into the foundation, and the positioning of the surveying and mapping device is more convenient.

[0009] Preferably, the inner wall of the movable block is slidably connected with four friction rods, and the four friction rods are distributed in a rectangle.

[0010] Preferably, the relative ends of the friction rods and the movable block are fixedly connected with first springs. Through the first springs and the friction rods, the friction rods are made to abut against the uneven ground, increasing the contact area between the surveying and mapping device and the ground, and improving the stability of the surveying and mapping device supported on the ground.

[0011] Preferably, the upper end of the inner wall of the movable frame is fixedly connected with a limiting ring.

[0012] Preferably, the inner bottom wall of the movable frame is fixedly connected with two second springs, and the top ends of the second springs are fixedly connected to the bottom of the movable block. Through the limiting ring, the elastic force of the second springs pushes the movable block upward to abut against the bottom of the limiting ring, and the limiting ring limits the upward movement position of the movable block, preventing the movable block from blocking the air outlet of the air delivery frame during upward movement.

[0013] Preferably, a sealing plug is threadedly connected to the lower end of the inner wall of the gas transmission frame. Through the sealing plug, the opening at the bottom end of the gas transmission frame is opened, so that the gas in the movable frame is discharged through the gas transmission frame, facilitating the subsequent extraction of the ground nails.

[0014] Preferably, an anti - detachment rod is fixedly connected to the inner wall of the gas transmission frame, and the surface of the anti - detachment rod penetrates and extends to the inner wall of the sealing plug. Through the anti - detachment rod, the downward movement position of the sealing plug is restricted, preventing the sealing plug from detaching from the bottom end of the gas transmission frame and reducing the risk of loss of the sealing plug.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. Through the sliding frame, sliding plate, elastic piece, positioning block and fixing block, the height of the movable block is adjusted and the adjusted sliding plate is locked, enabling the three ground nails to be evenly embedded into the foundation.

[0017] 2. Through the air pump and the gas transmission frame, gas is conveyed into the movable frame, enabling the three ground nails to be synchronously embedded into the foundation, making the positioning of the surveying device more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-4 shown, a surveying and mapping device for engineering geological foundation detection with an anti-tipping effect includes: a mounting plate 1, and a laser surveying and mapping instrument 2 is provided on the top of the mounting plate 1; a stabilizing mechanism 3, and the stabilizing mechanism 3 is arranged at the bottom end of the mounting plate 1; wherein, the stabilizing mechanism 3 includes sliding frames 31 annularly distributed and hinged to the inner side of the mounting plate 1, a sliding plate 32 is slidably connected to the inner wall of the sliding frame 31, a movable frame 33 is hinged to the lower end of the surface of the sliding plate 32, a movable block 34 is slidably connected to the inner wall of the movable frame 33, and the bottom of the movable block 34 is fixedly connected with ground-inserting nails 35 distributed in an equal column. A fixed block 37 is slidably connected to the inner wall of the sliding frame 31, a positioning block 36 distributed in an equal column is fixedly connected to the front end of the sliding plate 32, and an elastic sheet 38 is fixedly connected to the front end of the fixed block 37, and the front end of the elastic sheet 38 is fixedly connected to the inner wall of the sliding frame 31.

[0025] The upper end of the surface of the movable block 34 is a rubber member, and the upper end of the surface of the movable block 34 is closely attached to the inner wall of the movable frame 33.

[0026] When it is necessary to survey and map the engineering geological foundation, place the mounting plate 1 at the corresponding position of the building foundation to be surveyed and mapped. Open the three sliding frames 31 respectively and adjust the angular position of the movable frame 33. At this time, pull the fixed block 37 to make the fixed block 37 away from the surface of the positioning block 36, and pull the sliding plate 32 to the corresponding position in the sliding frame 31 to make the ground-inserting nails 35 better contact the foundation. Loosen the fixed block 37, and the elastic force of the elastic sheet 38 pushes the fixed block 37 to move, so that the fixed block 37 is inserted into the spacing between several adjacent positioning blocks 36, locking the sliding plate 32 in the sliding frame 31. According to the above process, make the three groups of ground-inserting nails 35 better contact the foundation, support the laser surveying and mapping instrument 2 stably. At this time, after calibrating the laser surveying and mapping instrument 2, the laser surveying and mapping instrument 2 emits a laser beam to scan the surface of the foundation, obtains high-precision three-dimensional point cloud data, analyzes the deformation and settlement of the foundation by laser scanning the surface of the foundation, and can obtain the strength data of the building foundation for construction personnel to take corresponding measures.

[0027] As Figures 3-4 shown, an air delivery frame 310 is fixedly connected to the bottom end of the mounting plate 1, the bottom end of the air delivery frame 310 is communicated with one side of the inner wall of the movable frame 33, and an air pump 311 is fixedly connected to the bottom end of the mounting plate 1, and the bottom end of the air pump 311 is communicated with the top end of the air delivery frame 310.

[0028] The air delivery frame 310 includes a corrugated hose and a circular frame. The top end of the circular frame is fixedly connected to the bottom end of the mounting plate 1. The bottom end of the circular frame is communicated with the top end of the corrugated hose, and the bottom end of the corrugated hose is communicated with one side of the inner wall of the air delivery frame 310.

[0029] Manually turn on the air pump 311. The air pump 311 extracts external air and conveys it to the three movable frames 33 through the air delivery frame 310 respectively. At this time, the gas in the movable frame 33 is sufficient to push the movable block 34 downward, so that the three groups of ground nails 35 are synchronously inserted into the foundation.

[0030] As Figure 3 shown, four friction rods 312 are slidably connected to the inner wall of the movable block 34. The four friction rods 312 are distributed in a rectangle. The relative ends of the friction rods 312 and the movable block 34 are fixedly connected with first springs 313.

[0031] The downward movement of the movable block 34 drives the four friction rods 312 to move downward at the same time, so that each friction rod 312 abuts against the corresponding ground. When one of the friction rods 312 abuts against the raised ground, the friction rod 312 will move upward to stretch the first spring 313. When another friction rod 312 contacts the concave ground, the elastic force of the first spring 313 pushes the friction rod 312 to abut against the concave ground, so that the contact area between the movable block 34 and the ground is increased.

[0032] As Figures 3-4 shown, a limiting ring 315 is fixedly connected to the upper end of the inner wall of the movable frame 33. Two second springs 314 are fixedly connected to the inner bottom wall of the movable frame 33. The top ends of the second springs 314 are fixedly connected to the bottom of the movable block 34. A sealing plug 316 is threadedly connected to the lower end of the inner wall of the air delivery frame 310. An anti - detachment rod 39 is fixedly connected to the inner wall of the air delivery frame 310. The surface of the anti - detachment rod 39 penetrates and extends into the inner wall of the sealing plug 316. There is a gap between the surface of the anti - detachment rod 39 and the inner cavity of the sealing plug 316.

[0033] After the surveying and mapping is completed, rotate the sealing plug 316 to make the sealing plug 316 away from the inner wall of the air delivery frame 310, so that the bottom opening of the air delivery frame 310 is opened. The gas in the movable frame 33 is discharged through the air delivery frame 310. At this time, pull the fixed block 37 to make the fixed block 37 away from the surface of the corresponding positioning block 36 and strongly pull the movable block 34. With the cooperation of the elastic force of the second spring 314, the ground nails 35 are disengaged from the foundation, and the three sliding frames 31 are aggregated, so that the mounting plate 1 and the stabilizing mechanism 3 can be carried.

[0034] When the utility model is in use, the mounting plate 1 is placed at the corresponding position of the building foundation to be surveyed. The three sliding frames 31 are respectively opened and the angular position of the movable frame 33 is adjusted. At this time, the fixing block 37 is pulled to make the fixing block 37 away from the surface of the positioning block 36. The sliding plate 32 is pulled to the corresponding position in the sliding frame 31, so that the ground anchor 35 can better contact the foundation. The fixing block 37 is loosened, and the elastic force of the elastic piece 38 pushes the fixing block 37 to move, so that the fixing block 37 is inserted into the space between several adjacent positioning blocks 36, and the sliding plate 32 is locked in the sliding frame 31. According to the above process, the three groups of ground anchors 35 can better contact the foundation. The air pump 311 is manually turned on, and the air pump 311 extracts external gas and conveys it to the three movable frames 33 through the air delivery frame 310 respectively. At this time, the gas in the movable frame 33 is sufficient and the movable block 34 is pushed down, so that the three groups of ground anchors 35 are synchronously inserted into the foundation. The downward movement of the movable block 34 drives the four friction rods 312 to move downward at the same time. With the cooperation of the first spring 313, each friction rod 312 abuts against the corresponding ground, so that the contact area between the movable block 34 and the ground is increased, and the laser surveying instrument 2 is stably supported. At this time, after the laser surveying instrument 2 is calibrated, the laser surveying instrument 2 emits a laser beam to scan the surface of the foundation, obtains high-precision three-dimensional point cloud data, and analyzes the deformation and settlement of the foundation by laser scanning the surface of the foundation, so as to obtain the strength data of the building foundation for the construction personnel to take corresponding measures.

[0035] It should be noted that in the above description, the mounting plate 1, the laser surveying instrument 2, the air pump 311, the friction rod 312, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the laser surveying instrument 2 and the air pump 311 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
