Description

Technical Field

[0001] The utility model relates to the technical field of foundation construction, and specifically relates to a positioning device for foundation construction. Background Technique

[0002] The foundation refers to the soil or rock mass that supports the foundation under a building. The soil layers serving as building foundations are divided into rock, gravel soil, sandy soil, silt, cohesive soil, and artificial fill. Foundations are of two types: natural foundations and artificial foundations (composite foundations). A natural foundation is a natural soil layer that does not require human reinforcement. Artificial foundations need to be reinforced by humans, and common ones include stone chip cushions, sand cushions, backfilling and ramming of mixed lime soil, etc.

[0003] For example, a positioning device for foundation construction disclosed in Chinese Patent (CN215407513U) includes a mounting base.

The side of the mounting base is fixedly connected to a push rod. The upper surface of the mounting base is fixedly connected to a longitudinal displacement mechanism. The longitudinal displacement mechanism is fixedly connected to a lateral displacement mechanism. The lateral displacement mechanism is threadedly connected to a positioning frame. By setting the universal wheel mechanism, the convenient movement of the overall device can be realized. By setting the floor anchor fixing mechanism, when work needs to be carried out, the support and fixation of the overall device can be completed to maintain the stability of the device. By setting the longitudinal displacement mechanism and the lateral displacement mechanism, the position of the positioning frame can be adjusted to achieve precise positioning, improve the positioning construction efficiency during foundation construction, and reduce the labor cost at the same time.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0021] Refer to Figures 1-4As shown in the figure, a positioning device for foundation construction includes four main bodies 1. A construction area to be constructed is formed among the four main bodies 1. A plurality of moving components 2 are fixedly installed on the bottom surface of the main body 1, and the plurality of moving components 2 are evenly distributed with respect to the bottom surface of the main body 1. After the moving components 2 are unfolded, the staff can fine-tune the area formed among the four main bodies 1 through the moving components 2. A chamber 3 is opened inside the main body 1. Reeling components 4 are arranged on the inner walls of the chambers 3 at both ends of the main body 1. A rotating shaft 20 is arranged inside the reeling component 4. A steel cable 5 is sleeved on the outer surface of the rotating shaft 20, and one end of the rotating shaft 20 is rotatably connected to the inner wall of the chamber 3. A through groove 6 is opened on the inner wall of the chamber 3 corresponding to the steel cable 5. Two support rods 7 are rotatably installed on the inner wall of the chamber 3 corresponding to the through groove 6, and the two support rods 7 are symmetrically distributed with respect to the center line of the through groove 6. The steel cables 5 between the two main bodies 1 close to each other form the side line of the foundation construction. The staff can apply paint on the surface of the steel cable 5 to make the steel cable 5 more eye-catching. After the construction is completed, the reeling component 4 can automatically reel in the steel cable 5. A handle 8 is arranged on the upper surface of the main body 1, and the staff can move the whole device to a suitable position through the handle 8.

[0022] As Figures 1-2 shown, the main board is L-shaped. The steel cable 5 is connected to the two main boards close to each other through the through groove 6. A sensor is fixedly installed on the upper surface of the main board corresponding to the steel cable 5. The L-shaped main board is located at the corner of the side line of the foundation construction. During the adjustment of the main board, the unfolding amount of the steel cable 5 between the two main boards close to each other is the same, and the staff directly reads the value through the sensor.

[0023] As Figure 3 shown, the moving component 2 includes a sleeve 9. A plurality of electric push rods 10 are arranged on the outer side of the sleeve 9, and the plurality of electric push rods 10 are circumferentially distributed around the center line of the sleeve 9. A fixed pipe 11 is sleeved on the outer surface of the sleeve 9, and the fixed pipe 11 is fixedly connected to the plurality of electric push rods 10. A plurality of sliding grooves 12 are opened on the outer surface of the sleeve 9 corresponding to the fixed pipe 11, and the plurality of sliding grooves 12 are circumferentially distributed around the center line of the sleeve 9. A sliding plate 13 is fixedly installed on the inner wall of the fixed pipe 11 corresponding to the sliding groove 12. A fixed rod 14 is rotatably installed on the inner wall of the sleeve 9, a moving plate 15 is fixedly installed at the lower end of the fixed rod 14, and a roller 16 is rotatably installed inside the moving plate 15. After the staff places the device at a suitable position and pushes the main board to a suitable position, the electric push rod 10 pushes the fixed pipe 11 to contact the ground while the roller 16 leaves the ground, so as to fix the main board at the corresponding position.

[0024] As Figure 4As shown, the winding assembly 4 includes a first fixed plate 17 and a second fixed plate 18, the first fixed plate 17 is fixedly connected to the inner wall of the chamber 3, a vortex spring sheet 19 is provided between the first fixed plate 17 and the second fixed plate 18, a rotating shaft 20 is rotatably installed at the center of the first fixed plate 17, the rotating shaft 20 is rotatably connected to the second fixed plate 18, the vortex spring sheet 19 is fixedly connected to the rotating shaft 20, when the two main boards close to each other are separated from each other, the steel cable 5 drives the rotating shaft 20 to rotate, thereby causing the vortex spring sheet 19 to deform, and when the construction is completed, when the two main boards close to each other are close to each other, the vortex spring sheet 19 causes the rotating shaft 20 to rotate by resetting, thereby causing the steel cable 5 to be wound.

[0025] As shown in Figure 1-2, a buffer pad 21 is fixedly installed on the side where the two main bodies 1 are close to each other. When the two main bodies 1 are close to or in contact with each other, the buffer pad 21 can effectively reduce the direct collision between them. Due to the complex environment of the foundation construction site, the main body 1 may have a slight collision or friction during the movement or positioning process. The presence of the buffer pad 21 can absorb part of the impact energy and reduce the damage caused by the collision, thereby extending the service life of the main body 1.

[0026] like Figures 2-4 As shown, the first fixing plate 17 and the second fixing plate 18 adopt an interference fit, and the fitting tolerance is 1mm-2mm. This fitting tolerance allows the first fixing plate 17 and the second fixing plate 18 to generate a certain pre-tightening force after assembly. This pre-tightening force can ensure that the two fixing plates fit tightly and are not prone to loosening or falling off, thereby enhancing the structural stability of the entire winding assembly 4. At the same time, the interference fit allows the staff to easily disassemble the first fixing plate 17 and the second fixing plate 18 when maintaining the equipment, thereby facilitating the maintenance of the equipment.

[0027] like Figures 1-3 As shown, a friction plate 22 is fixedly installed at the lower end of the fixed tube 11. When the main board moves to a suitable position, the friction plate 22 contacts the bottom surface. The friction plate 22 can effectively increase the friction between the fixed tube 11 and the ground, thereby enhancing the grip of the device and preventing it from sliding or shifting when subjected to force.

[0028] Working principle: After the staff place the device in the target area, multiple staff members respectively push the corresponding main boards. The roller 16 rotates to facilitate the staff to push the main boards. At the same time, when the two main boards are separated from each other, the steel cable 5 drives the rotating shaft 20 to rotate, thereby deforming the spiral spring piece 19. During the movement of the main board, the staff reads the values on the sensor. When the values reach the expectation, the staff stop moving the main board. The electric push rod 10 pushes the friction plate 22 on the fixed pipe 11 to contact the ground while the roller 16 leaves the ground, so that the main board is fixed in a proper position. After the foundation construction is completed, when the two mutually approaching main boards approach each other, the spiral spring piece 19 makes the rotating shaft 20 rotate through reset, so that the steel cable 5 is wound up. The user can move the device to the next area through the handle 8.

[0029] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
