Detailed implementation mode
[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.
[0022] The present utility model provides a construction device for excavation of deep foundation pits without lowering water level and draining water, as Figure 1 shown, which includes a sand suction pump 1, a high-pressure nozzle 2, a motor 3 and a floating raft 4. The floating plate 4 floats correspondingly on the water surface of the foundation pit. The output end of the sand suction pump 1 is set as the high-pressure nozzle 2, and the high-pressure nozzle 2 is externally connected to a discharge pipe. The bottom surfaces of the sand suction pump 1 and the motor 3 are fixedly connected through a bottom plate 5, and the bottom plate 5 is correspondingly installed on the top surface of the floating raft 4 through a plurality of screws. The output end of the motor 3 and the output end of the sand suction pump 1 are connected by a belt 6 for transmission. A sand pumping port 7 is arranged on one side of the sand suction pump 1, and a hose 8 is arranged on one side of the sand suction pump 1. The inner end of the hose 8 is sleeved on the surface of the sand pumping port 7, and the outer end of the hose 8 is connected to the top end of a vertical pipe 9. The bottom end of the vertical pipe 9 extends into the foundation pit. One end of the hose 8 is tightly sleeved on the surface of the sand pumping port 7. When the motor 3 works, the sand suction pump 1 is driven to work by the belt 6. The working sand suction pump 1 uses the vertical pipe 9 at the outer end of the hose 8 to pump the sand and gravel inside the foundation pit. The sand and gravel inside the foundation pit enter the sand suction pump 1 through the vertical pipe 9 and the hose 8. The sand suction pump 1 discharges the pumped sand and gravel through the discharge pipe connected to the high-pressure nozzle 2. A clamping component for limiting the vertical pipe 9 is installed on the top surface of the floating raft 4. The clamping component includes two relatively arranged support plates 10. The concave surface of the support plate 10 corresponds to the outer circumferential surface of the vertical pipe 9. The clamping component clamps the vertical pipe 9 by the cooperation of the two support plates 10. When the clamping component on the top of the floating raft 4 clamps the vertical pipe 9 correspondingly by the two support plates 10, the vertical pipe 9 is in a stable state during the process of pumping sand and gravel, avoiding the wanton swing of the vertical pipe 9.
[0023] In Figure 1 and Figure 2Among them, the clamping component includes two relatively arranged side frames 11. The two side frames 11 are respectively located on both sides of the hose 8. A screw rod 12 is arranged inside the side frame 11. The top end of the screw rod 12 penetrates through the top surface of the side frame 11. A sliding plate 13 is fixed to the bottom end of the screw rod 12. A side groove corresponding to the sliding plate 13 is arranged on the surface of the side frame 11. Two relatively arranged clamping plates 14 are fixed to the top surface of the side frame 11. A toothed ring 15 is sleeved on the surface of the clamping plate 14. The toothed ring 15 is spirally sleeved on the surface of the screw rod 12. The toothed rings 15 at the tops of the two side frames 11 are meshed and cooperated by a toothed belt 16. The two sliding plates 13 are fixedly connected by a connecting plate 17. The hose 8 is correspondingly placed on the top of the connecting plate 17. When the toothed ring 15 is rotated, since the top end of the side frame 11 limits the toothed ring 15 by two clamping plates 14, the rotating toothed ring 15 drives another toothed ring 15 to rotate synchronously by the toothed belt 16, and the spiral effect of the rotating toothed ring 15 and the screw rod 12 causes the screw rod 12 to drive the sliding plate 13 to move up and down inside the side groove.
[0024] The upward moving sliding plate 13 drives the hose 8 and the vertical pipe 9 to move upward by the connecting plate 17. The sliding plate 13 drives the connecting plate 17 to move downward. The weight of the vertical pipe 9 itself causes the hose 8 to move downward following the sliding plate 13.
[0025] In Figures 2 to 4 Among them, the clamping component further includes two relatively arranged sliding frames 18. The sliding frames 18 are correspondingly sleeved on the surface of the connecting plate 17. The two frame plates 10 and the two sliding frames 18 correspond one by one. A convex plate 19 corresponding to the frame plate 10 is fixed to the bottom of the sliding frame 18. A convex rod 20 penetrating through the convex plate 19 is fixed to the side surface of the frame plate 10. The two convex rods 20 are connected by a limiting component. When the sliding frame 18 slides on the surface of the connecting plate 17, the sliding connecting plate 17 drives the frame plate 10 to move by the convex plate 19 and the convex rod 20. The moving frame plate 10 moves closer to or away from the vertical pipe 9. The connecting plate 17 is arranged as a square rod, and the sliding frame 18 is arranged as a square frame. When the sliding frame 18 slides on the surface of the connecting plate 17, since the square frame slides on the surface of the square rod, the sliding frame 18 will not rotate on the surface of the connecting plate 17. The two frame plates 10 are always relatively arranged. The two relatively close sliding frames 18 clamp the vertical pipe 9 by the concave surfaces of the two frame plates 10, so that the vertical pipe 9 is always in a vertical state.
[0026] In Figures 2 to 4Among them, the limiting component includes a plug rod 21, and the plug rod 21 correspondingly penetrates through the centers of the two convex rods 20. Nuts are spirally sleeved at both ends of the plug rod 21, and the inner side surfaces of the nuts are in contact with the outer side surfaces of the convex rods 20. After the hose 8 is placed on the top of the connecting plate 17, the sliding frame 18 is pushed to move. At this time, when the two support plates 10 are both attached to the surface of the vertical pipe 9 by using the concave surfaces, the plug rod 21 is successively penetrated through the two convex rods 20, and the two nuts are respectively spirally sleeved at both ends of the plug rod 21. The spiral effect of the nuts and the plug rod 21 enables the two support plates 10 to tightly clamp the vertical pipe 9. Through the cooperation of the limiting component and the sliding frame 18, it is convenient for the two support plates 10 to cooperate to clamp vertical pipes 9 with different outer diameters.
[0027] A spring piece 22 is arranged between the support plate 10 and the convex plate 19. One end of the spring piece 22 is connected to the support plate 10, the other end of the spring piece 22 is connected to the convex plate 19, and the spring piece 22 is in a straight state. After the clamping component uses the two support plates 10 to cooperate to clamp the vertical pipe 9, the elastic force of the spring piece 22 enables the support plate 10 to move away from the convex plate 19, avoiding the vertical pipe 9 from colliding with the convex plate 19 during the process of extracting sand and gravel, and at the same time using the elastic force of the spring piece 22 to absorb the vibration generated by the vertical pipe 9 during the process of extracting sand and gravel.
[0028] The working principle of the present utility model:
[0029] Refer to Figures 1 to 4 As shown, the hose 8 is correspondingly placed on the top of the connecting plate 17. When the sliding frame 18 slides on the surface of the connecting plate 17, since the square frame slides on the square rod, the sliding frame 18 will not rotate on the surface of the connecting plate 17, and the two support plates 10 are always arranged oppositely. After the two relatively close sliding frames 18 use the concave surfaces of the two support plates 10 to correspondingly clamp the vertical pipe 9, the plug rod 21 is successively penetrated through the two convex rods 20, and the two nuts are respectively spirally sleeved at both ends of the plug rod 21. The spiral effect of the nuts and the plug rod 21 enables the two support plates 10 to tightly clamp the vertical pipe 9. Through the cooperation of the limiting component and the sliding frame 18, it is convenient for the two support plates 10 to cooperate to clamp vertical pipes 9 with different outer diameters.
[0030] Turn the toothed ring 15. Since the top end of the side frame 11 limits the toothed ring 15 by using the two clamping plates 14, the rotating toothed ring 15 drives another toothed ring 15 to rotate synchronously by using the toothed belt 16, and the spiral effect of the rotating toothed ring 15 and the screw rod 12 enables the screw rod 12 to drive the sliding plate 13 to move up and down inside the side groove until the bottom end of the vertical pipe 9 extends into the foundation pit.
[0031] One end of the hose 8 is tightly sleeved on the surface of the sand suction port 7. The motor 3 works to make the sand suction pump 1 work by using the belt 6. The working sand suction pump 1 extracts the sand and gravel in the foundation pit by using the vertical pipe 9 at the outer end of the hose 8. The sand and gravel in the foundation pit enter the sand suction pump 1 through the vertical pipe 9 and the hose 8, and the sand suction pump 1 discharges the extracted sand and gravel through the discharge pipe connected to the high-pressure nozzle 2.
[0032] After the clamping member clamps the vertical pipe 9 by means of two support plates 10, the elastic force of the elastic piece 22 causes the support plate 10 to move away from the convex plate 19, avoiding the collision between the vertical pipe 9 and the convex plate 19 during the process of extracting sand and gravel. At the same time, the elastic force of the elastic piece 22 is used to absorb the vibration generated by the vertical pipe 9 during the process of extracting sand and gravel.
[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
