Description

Technical Field

[0001] The invention belongs to the technical field of pile foundation detection, and in particular relates to a pile foundation detection fixing device for engineering detection. Background Art

[0002] Engineering inspection is an important task to ensure the safety of construction projects that have been built, are under construction, and will be built. It tests the foundation, building materials, construction technology, and building structure related to the building during the entire construction process. Therefore, it is necessary to determine the location of defects. During the process of pile foundation inspection, the piles need to be fixed to ensure the accuracy of the inspection device.

[0003] The existing patent with announcement number CN114319470A relates to an engineering foundation pile detection and fixing device for construction engineering detection, including a frame body, rod bodies that are slidably provided on all four sides of the frame body and move toward or away from the center of the frame body, each rod body is provided with a column, and a connecting rod is fixedly provided at the end of each column away from the rod body; each of the connecting rods is slidably provided with a plurality of moving rods along its length direction, and a plurality of moving rods on the same connecting rod are slidably provided with an elastic arc rod at the end away from the connecting rod; the moving rods are provided with a second fixing member for fixing the moving rod to any moved position, and the arc rods are provided with a second fixing member for fixing the arc rod to any moving position. The third fixing piece is used to fix the third sliding block to any position in the third sliding groove; the connecting rod is provided with a second sliding groove, and one end of the moving rod is fixedly provided with a second sliding block, and the second sliding block is limitedly slidably set in the second sliding groove, and the second fixing piece is used to fix the second sliding block to any position in the second sliding groove; the arc rod is provided with a third sliding groove, and the other end of the moving rod is fixedly provided with a third sliding block, and the third sliding block is limitedly slidably set in the third sliding groove, and the third fixing piece is used to fix the third sliding block to any position in the third sliding groove; the moving rod includes a fixed rod and a plug-in rod slidably plugged in the fixed rod, and the fixed rod is provided with a fourth fixing piece for fixing the plug-in rod to any position in the fixed rod.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the above-mentioned scheme fixes the foundation piles of different peripheral specifications, the fixed rod and several plug-in rods are first spliced ​​into several mobile rods through the fourth fixing member, and then several mobile rods are slid. The sliding of the mobile rod will drive the second sliding block and the third sliding block to slide synchronously. After the second sliding block slides to the appropriate position, the second sliding block is fixed by the second fixing member, and the third sliding block is fixed by the third fixing member, thereby completing the deployment of the arc rod. Several mobile rods need to be slid during each adjustment process, and the fixing of the sliding block by the fixing member needs to be released before each sliding, and the sliding block needs to be re-fixed by the fixing member after sliding. The overall adjustment process is complicated to operate, and repeated adjustment of the fixing member will increase the deployment time of the arc rod of the above-mentioned scheme, and the overall practicality is low.

[0039] Limit blocks (not shown in the figure) are fixedly provided at the ends of the second screw rod 9, the third screw rod 10 and the fourth screw rod 11 away from the center of the frame 1, which are used to prevent the second screw rod 9 from detaching from the second sleeve 26, the third screw rod 10 from detaching from the third sleeve 35, and the fourth screw rod 11 from detaching from the fourth sleeve 38.

[0040] A first hinge block 33 is rotatably provided at the end of each second screw rod 9 facing the center of the frame 1, and a second hinge block 34 is rotatably provided at the end of each third screw rod 10 and fourth screw rod 11 facing the center of the frame 1. An arc rod 13 is fixedly provided at the other end of each first hinge block 33, and the arc rod 13 is located in the middle position of the first hinge block 33. The outer wall of each arc rod 13 is provided with a second slide groove 12, and the number of the second slide grooves 12 is equal to and corresponds to the fixed rod 7. The second hinge blocks 34 connected to the third screw rod 10 and the fourth screw rod 11 located on the same fixed rod 7 are all limitedly slidably provided in the second slide groove 12 corresponding to the fixed rod 7.

[0041] The arc rod 13 itself has a certain elasticity, and is specifically made of a rubber material, which facilitates the fixation of foundation piles of different specifications.

[0042] Working principle: First, four mounting rods are spliced ​​together by bolts 2. Then the foundation pile is moved between the four arc rods 13, and the arc rods 13 do not contact the foundation pile.

[0043] The first motor 18 is started, and the output shaft of the first motor 18 drives the first rotating shaft 19 to rotate. The rotation of the first rotating shaft 19 drives the first gear 17 to rotate, thereby driving the rod body 3 to slide toward the direction close to the foundation pile through the rack 14. During the sliding process of the rod body 3, the sliding rod 5, the fixed rod 7 and the arc rod 13 are driven to move synchronously. When the rod body 3 moves to a suitable position, the first motor 18 is stopped.

[0044] When a pile with a larger diameter needs to be fixed, the second motor 20 is started. The output shaft of the second motor 20 drives the second gear 21 to rotate, and the second gear 21 drives the first sleeve 24 to rotate through the third gear 23. The rotation of the first sleeve 24 drives the sliding rod 5, the fixing rod 7 and the arc rod 13 to move in a direction away from the pile.

[0045] At the same time, the rotation of the first sleeve 24 drives the first driving wheel 22 to rotate, and then drives the first driven wheel 27 to rotate synchronously through the first belt 15. The rotation of the first driven wheel 27 drives the second rotating shaft 32 to rotate, and the second rotating shaft 32 drives the fifth gear 29, the second driving wheel 31 and the third driving wheel 39 to rotate synchronously.

[0046] The rotation of the fifth gear 29 drives the second sleeve 26 to rotate through the fourth gear 25, thereby driving the second screw rod 9 to move toward the direction close to the pile relative to the fixed rod 7. Then, the middle position of the arc rod 13 is pushed to move toward the center of the pile relative to the fixed rod 7 through the first hinge block 33.

[0047] During this process, the second driving wheel 31 drives the third driven wheel 37 to rotate through the third belt 30. The rotation of the third driven wheel 37 drives the fourth sleeve 38 to rotate, thereby driving the fourth screw rod 11 to move in a direction away from the pile relative to the fixed rod 7. Under the synchronous rotation of the second screw rod 9, the fourth screw rod 11 will drive the second hinge block 34 connected thereto to slide in the corresponding second slide groove 12. During this process, the fourth screw rod 11 will also pull the sliding contact between the arc rod 13 and the second hinge block 34 through the second hinge block 34 to move relative to the fixed rod 7 in a direction away from the center of the pile, thereby causing one end of the arc rod 13 to move relative to the fixed rod 7 in a direction away from the pile.

[0048] At the same time, the third driving wheel 39 drives the second driven wheel 36 to rotate through the second belt 28. The rotation of the second driven wheel 36 drives the third sleeve 35 to rotate, thereby driving the third screw rod 10 to move in a direction away from the pile relative to the fixed rod 7. Under the synchronous rotation of the second screw rod 9, the third screw rod 10 will drive the second hinge block 34 connected thereto to slide in the corresponding second slide groove 12. In this process, the third screw rod 10 will also pull the sliding contact between the arc rod 13 and the second hinge block 34 through the second hinge block 34 to move relative to the fixed rod 7 in a direction away from the center of the pile, thereby causing the other end of the arc rod 13 to move relative to the fixed rod 7 in a direction away from the pile.

[0049] Finally, the middle of the arc rod 13 moves toward the center of the pile, and the two ends of the arc rod 13 move toward the direction away from the center of the pile, so as to facilitate clamping of a pile with a larger diameter.

[0050] When a foundation pile with a smaller diameter needs to be fixed, the output shaft of the second motor 20 is controlled to rotate in the opposite direction. The output shaft of the second motor 20 drives the second gear 21 to rotate, and the second gear 21 drives the first sleeve 24 to rotate through the third gear 23. The rotation of the first sleeve 24 drives the sliding rod 5, the fixing rod 7 and the arc rod 13 to move in the direction close to the foundation pile.

[0051] At the same time, the rotation of the first sleeve 24 drives the first driving wheel 22 to rotate, and then drives the first driven wheel 27 to rotate synchronously through the first belt 15. The rotation of the first driven wheel 27 drives the second rotating shaft 32 to rotate, and the second rotating shaft 32 drives the fifth gear 29, the second driving wheel 31 and the third driving wheel 39 to rotate synchronously.

[0052] The rotation of the fifth gear 29 drives the second sleeve 26 to rotate through the fourth gear 25, thereby driving the second screw rod 9 to move in a direction away from the pile relative to the fixed rod 7. Then, the middle position of the arc rod 13 is pulled by the first hinge block 33 to move in a direction away from the center of the pile relative to the fixed rod 7.

[0053] During this process, the second driving wheel 31 drives the third driven wheel 37 to rotate through the third belt 30. The rotation of the third driven wheel 37 drives the fourth sleeve 38 to rotate, thereby driving the fourth screw rod 11 to move in the direction close to the foundation pile relative to the fixed rod 7. Under the synchronous rotation of the second screw rod 9, the fourth screw rod 11 will drive the second hinge block 34 connected thereto to slide in the corresponding second slide groove 12. During this process, the fourth screw rod 11 will also push the sliding contact between the arc rod 13 and the second hinge block 34 to move in the direction close to the center of the foundation pile relative to the fixed rod 7 through the second hinge block 34, so that one end of the arc rod 13 moves in the direction close to the foundation pile relative to the fixed rod 7.

[0054] At the same time, the third driving wheel 39 drives the second driven wheel 36 to rotate through the second belt 28. The rotation of the second driven wheel 36 drives the third sleeve 35 to rotate, thereby driving the third screw rod 10 to move in the direction close to the foundation pile relative to the fixed rod 7. Under the synchronous rotation of the second screw rod 9, the third screw rod 10 will drive the second hinge block 34 connected thereto to slide in the corresponding second slide groove 12. In this process, the third screw rod 10 will also push the sliding contact point between the arc rod 13 and the second hinge block 34 to move in the direction close to the center of the foundation pile relative to the fixed rod 7 through the second hinge block 34, so that the other end of the arc rod 13 moves in the direction close to the foundation pile relative to the fixed rod 7.

[0055] Finally, the middle position of the arc rod 13 moves away from the center of the pile, and the two ends of the arc rod 13 move toward the center of the pile, so as to facilitate clamping of a pile with a smaller diameter.

[0056] After the adjustment is completed, the second motor 20 is stopped. The first motor 18 is started, so that the arc rod 13 moves toward the direction close to the foundation pile, and finally the arc rod 13 clamps the foundation pile, thereby completing the fixing of the foundation pile.
