Description

Technical Field

[0001] The invention belongs to the technical field of building construction, in particular to a high-efficiency building pile foundation construction device and an operation method thereof. Background Art

[0002] Building pile foundation construction is an important part of building foundation engineering, involving multiple steps and regulations; its pile foundation construction includes measurement and layout, casing setting and pile driver positioning, circulation system layout, drilling (punching) holes, and steel cage production and installation.

[0003] In the prior art, when constructing a building pile foundation, it is necessary to put a steel cage into a casing. After the depth of the pile foundation hole reaches a certain standard, the steel cage needs to be placed in multiple sections. When the multiple sections of the steel cage are placed, one section of the steel cage is placed first, and then supported at the casing hole by one or two support columns, and then one section of the steel hole is lifted and hung above the previous section of the steel cage for "full wire-half wire" or welding to ensure the integrity of the multiple sections of the steel cage; however, there are the following problems: first, because the steel cage is lifted and placed, when the casing is placed, there will be a deviation between the center of the casing and the center of the steel cage, and the deviation is too large to affect the formation quality of the pile foundation; second, when the upper and lower steel cages are "full wire-half wire" or welded, because the upper steel cage is lifted by a crane, the upper steel cage swings during processing, which affects the processing efficiency.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figures 1 to 8As shown, an efficient construction device for building pile foundations according to an embodiment of the present invention comprises a casing 1 and an annular chassis 11; the annular chassis 11 is sleeved on the outside of the casing 1; the top of the annular chassis 11 is rotatably connected to an annular rotating disk 12; the annular rotating disk 12 is positioned on the annular chassis 11 by a positioning member; a group of support blocks 13 are fixedly connected to the top position of the annular rotating disk 12 near the inner ring wall; a first through groove 14 is opened on the upper side wall of the support block 13; a U-shaped plate 15 is fixedly connected to the side wall of the support block 13, and the opening of the U-shaped plate 15 and the first through groove 14 correspond to each other, and the two are connected to each other; the annular rotating disk A group of first slide grooves 16 are provided at the top of 12, and the first slide grooves 16 are located below the U-shaped plate 15; an inverted L-shaped block 17 is slidably connected in the first slide groove 16, and the vertical block side wall of the inverted L-shaped block 17 is slidably connected in the U-shaped plate 15, and the bottom end of the horizontal block of the inverted L-shaped block 17 is slidably connected to the top of the support block 13; the inverted L-shaped block 17 is pushed by a moving member; a second through groove 18 is provided on the horizontal block of the inverted L-shaped block 17, and a lifting block 2 is slidably connected in the second through groove 18; a pushing plate 21 is fixedly connected to the bottom end of the lifting block 2, and one side of the pushing plate 21 passes through the first through groove 14 and extends into the U-shaped plate 15 and is slidably connected to On the vertical side wall of the inverted L-shaped block 17; the lifting block 2 moves up and down through the lifting member; the top of the annular rotating disk 12 is connected with a group of fixed columns 592 by bolts, and a stabilizing mechanism is provided on the fixed columns 592, and a group of fixed columns 592 and a group of support blocks 13 are staggered; a pressure sensor 22 is provided in the side wall of the lifting block 2 close to the support block 13; in the prior art, when constructing the building pile foundation, it is necessary to put the steel cage into the casing. After the depth of the pile foundation hole reaches a certain standard, the steel cage needs to be placed in multiple sections. When the multiple sections of the steel cage are placed, one section of the steel cage is placed first, and then supported by one or two support columns At the casing hole, a section of the steel bar hole is then hoisted and suspended above the previous section of the steel cage for "full wire-half wire" or welding to ensure the integrity of the multi-section steel cage; however, there are the following problems: First, because the steel cage is hoisted and placed, there will be a deviation between the center of the casing and the center of the steel cage when the casing is placed. Excessive deviation affects the quality of the pile foundation; Second, when the upper and lower steel cages are "full wire-half wire" or welded, because the upper steel cage is hoisted by a crane, the upper steel cage swings during processing, affecting the processing efficiency. Welding under unstable conditions will also affect the welding quality of the upper and lower steel cages;Therefore, when the present invention is working, the annular chassis 11 and the annular rotating disk 12 are both sleeved on the outside of the casing 1. When a section of the steel cage is about to be placed, the inverted L-shaped block 17 is driven to move by the moving part, so that the end of the inverted L-shaped block 17 extends into between the adjacent main bars (the steel cage is composed of main bars, welded stiffening hoops and spiral stirrups). At this time, a group of inverted L-shaped blocks 17 move to the position where the lifting block 2 extends upward through the lifting member. At this time, parts of a group of inverted L-shaped blocks 17 will be inside the steel cage. Then, when the crane is completely below the steel cage, the bottom end of the welded stiffening hoop will fit above the inverted L-shaped block 17 to support the steel cage placed in the casing 1. Then, the inverted L-shaped block 17 is driven to move in the opposite direction by the moving part. During the movement, the lifting block 2 will fit together with the welded stiffening hoop, thereby pushing the entire steel cage to deflect. After the pressure sensors 22 in the lifting block 2 on the L-shaped block 17 are within the rated standard, it indicates that the steel cage offset is completed. At this time, the center point of the steel cage basically coincides with the center of the casing 1. At the same time, the steel cage placed again by the crane is in the upper position. Then, the stability of the upper steel cage is adjusted by the stabilizing mechanism to allow it to move down stably, so that the upper and lower main bars are welded and processed to complete the docking. Then, the lifting block 2 is retracted into the second through groove 18 by the lifting member, and the inverted L-shaped block 17 is separated from the steel cage as a whole. The above operation is repeated to complete the placement of the multi-section steel cage. At the same time, the present invention sets the lifting block 2 at a position close to the horizontal side end of the inverted L-shaped block 17, and uses the pulling method to adjust the steel cage, which can effectively increase the scope of application of the device, and does not only work for pile foundation holes of a single size. ;

[0022] The lifting member includes a sliding column 3; first grooves 31 are provided on the side walls of both sides of the push plate 21, and the sliding column 3 is fixedly connected to the bottom of the first groove 31 through a spring; upper sliding grooves 32 and lower sliding grooves 33 are provided on the side walls of the U-shaped plate 15 and the first through groove 14, and the upper sliding groove 32 is located above the lower sliding groove 33; a through groove 34 is provided on the side wall of the first through groove 14, and the upper sliding groove 32 and the lower sliding groove 33 are connected to each other through the through groove 34; an inclined groove 35 is provided on the side wall of the first through groove 14, and the upper sliding groove 32 and the lower sliding groove 33 are connected to each other through the inclined groove 35, and the inclined groove 35 is arranged to be inclined upward, and the inclined groove The highest point of 35 coincides with the tail of the upper slide groove 32; a stopper 36 is fixedly connected to the upper slide groove 32, and the side wall of the stopper 36 and the side wall of the inclined groove 35 are parallel and fitted to each other, and a first inclined surface 37 is provided on the other side wall of the stopper 36; a support plate 39 is fixedly connected to the bottom of the first through groove 14 through a spring, and the push plate 21 is slidably connected to the top of the support plate 39; a folding plate 38 is fixedly connected to the lower slide groove 33; the inclined plate of the folding plate 38 and the inclined surface of the inclined groove 35 are parallel and fitted to each other, the horizontal plate of the folding plate 38 is located directly below the through groove 34, and the length of the horizontal plate is greater than the opening length of the through groove 34; The moving part includes a first servo motor 4; a first annular cavity 41 is provided in the annular rotating disk 12; the first annular cavity 41 and the first slide groove 16 are connected to each other; a first lead screw 42 is rotatably connected in the first slide groove 16, and the vertical block of the inverted L-shaped block 17 is connected to the first lead screw 42 through a lead screw nut pair, and the end of the first lead screw 42 extends into the first annular cavity 41 and is fixedly connected to a first gear 43; a first annular rack 44 is rotatably connected to the bottom of the first annular cavity 41, and the first annular rack 44 and the first gear 43 are meshed with each other; a first servo motor 4 is fixedly connected to the top of the annular rotating disk 12, and the output of the first servo motor 4 extends into the annular rotating disk 12 and is fixedly connected to a second gear 45, and the second gear 45 and the inner ring wall of the first annular rack 44 are meshed with each other; The first servo motor 4 drives the first annular rack 44 to rotate through the second gear 45, and then drives the first lead screw 42 to rotate through the meshing of the first annular rack 44 and the first gear 43, so that the inverted L-shaped block 17 moves toward the center point of the casing 1, and at the same time, the pushing plate 21 will follow the inverted L-shaped block 17 to move, allowing the sliding column 3 to move in the sliding groove 33. When the sliding column 3 moves to the through groove 34 position, the pushing plate 21 is subjected to an upward supporting force (provided by the spring of the support plate 39) when it is in the sliding groove 33. Then, after the sliding column 3 reaches the through groove 34, the pushing plate 21 will be pushed upward by the support plate 39, and the sliding column 3 enters the upper slide groove 32 from the through groove 34, and the lifting block 2 extends out of the upper slide groove 32. At this time, the forward movement of the inverted L-shaped block 17 is completed, and the inverted L-shaped block 17 is partially located in the steel cage. Then the crane lowers the steel cage to place the welded stiffening hoop on the inverted L-shaped block 17, and then the inverted L-shaped block 17 shrinks as a whole (the sliding column 3 moves in the upper slide groove 32 at this time). The position of the steel cage is adjusted by using the lifting block 2. After the upper and lower steel cages are connected, the inverted L-shaped block 17 moves forward again to allow the sliding column 3 to move in the upper slide groove 32 until a group of inverted L-shaped blocks 17 moves to the final point. Then, the inverted L-shaped block 17 is reversed to restore to its original position. At this time, the sliding column 3 will pass through the first inclined surface 37 of the block 36 and enter the connection between the inclined groove 35 and the upper slide groove 32. When the inverted L-shaped block 17 shrinks and returns to its original position again, the sliding column 3 will be blocked by the inclined surface 37 of the block 36. The push plate 21 is pulled downward by the inclined surface of the inclined groove 35 until the sliding column 3 enters the lower sliding groove 33 again, and then the sliding column 3 moves along the folding plate 38. Because the horizontal plate of the folding plate 38 just covers the opening of the through groove 34, the sliding column 3 can slide in the lower sliding groove 33 until the inverted L-shaped block 17 returns to its original position. At the same time, the lifting block 2 will also follow the movement of the inverted L-shaped block 17 in the second through groove 18 and return to its original position without being blocked by the welded stiffening hoop.

[0023] The stabilizing mechanism comprises an arc block 5; the middle part of the arc block 5 slides on the fixed column 592; arc grooves 51 are provided on the side walls at both ends of the arc block 5; third through grooves 52 are provided on both sides of the arc groove 51; a second slide groove 53 is provided at the top of the arc groove 51; an arc slider 54 is slidably connected in the arc groove 51; a first threaded column 56 is threadedly connected to the arc slider 54, and the top of the first threaded column 56 extends out of the arc block 5 through the second slide groove 53; a through hole 57 is provided on the side wall of the arc slider 54, and a limiting column 58 is slidably connected in the through hole 57, and the top cross-section of the limiting column 58 is an I-shape; the limiting column 58 is magnetic and is mutually adsorbed with the inner wall of the through hole 57; the arc block 5 is limited by a sliding unit; The sliding unit includes a locking hole 59 and a second threaded column 591; a group of locking holes 59 are opened on the side wall of the fixing column 592; and the second threaded column 591 is threadedly connected on the side wall of the arc block 5; When the upper and lower steel cages need to be docked, the arc block 5 is moved up to a suitable position as a whole, and then the second threaded column 591 and the positioning hole 59 are used to limit the position. Then the limiting column 58 is pushed between the relative main bars, and then the position of the steel cage hoisted by the crane is manually adjusted. After the position is aligned with the processing position of the lower steel cage, the position of a pair of arc sliders 54 is adjusted so that the limiting columns 58 thereon and the adjacent main bars are in contact with each other. Then the screw cap on the first threaded column 56 is used to squeeze the top of the arc block 5 to limit the limiting column 58 at this time. At this time, the upper steel cage can basically no longer rotate left and right, or deviate as a whole (the arc block 5 is a group, not one), thereby ensuring that the upper steel cage can stably move down to the processing position. At the same time, during the docking process, a stable state can also be guaranteed.

[0025] The locking member includes a locking groove 72; a group of locking grooves 72 are opened on the top of the annular chassis 11; a positioning block 7 is fixedly connected to the outer wall of the annular rotating disk 12, and the positioning block 7 is penetrated by a locking column 71 for sliding connection; during operation, in order to ensure that the horizontal block of the inverted L-shaped block 17 can enter the adjacent main rib space, it is necessary to rotate the annular rotating disk 12 in a targeted manner to adjust the appropriate position, and then lock it into the locking groove 72 through the locking column 71 to maintain stability.

[0027] An operating method of a building pile foundation efficient construction device, the operating method is applicable to the above-mentioned building pile foundation efficient construction device, the method steps are as follows: S1: When a section of the steel cage is about to be placed by the crane, the inverted L-shaped block 17 is moved by the moving member, so that the end of the inverted L-shaped block 17 extends between adjacent main bars, and the lifting block 2 extends upward through the lifting member; S2: When the crane is completely under the steel cage, the bottom end of the welded stiffening hoop will fit above the inverted L-shaped block 17 to support the steel cage placed in the casing 1.

During the movement, the lifting block 2 will fit with the welded stiffening hoop, thereby promoting the offset adjustment of the entire steel cage. S3: Lift the steel cage again by the crane to the upper position, then adjust the position of the upper steel cage by the stabilizing mechanism to make it stably move downward, perform welding processing between the upper and lower main bars, complete the docking, then retract the lifting block 2 into the second through groove 18 by the lifting member, and then separate the inverted L-shaped block 17 from the steel cage as a whole, repeat the above operation, and then complete the placement of the multi-section steel cage.

[0028] Working principle: the annular chassis 11 and the annular rotating disk 12 are both sleeved on the outside of the casing 1. When a section of the steel cage is about to be placed, the inverted L-shaped block 17 is driven to move by the moving part, so that the end of the inverted L-shaped block 17 extends into the adjacent main bars (the steel cage is composed of main bars, welded stiffening hoops and spiral stirrups). At this time, a group of inverted L-shaped blocks 17 move to the lifting block 2 and extend upward through the lifting part. At this time, part of a group of inverted L-shaped blocks 17 will be in the steel cage. Then when the crane is completely below the steel cage, the bottom end of the welded stiffening hoop will fit above the inverted L-shaped block 17 to support the steel cage placed in the casing 1. Then the inverted L-shaped block 17 is driven to move in the opposite direction by the moving part. During the movement, the lifting block 2 will fit together with the welded stiffening hoop, thereby pushing the entire steel cage to offset until a group of inverted After the pressure sensors 22 in the lifting block 2 on the L-shaped block 17 are within the rated standard, it indicates that the displacement of the steel cage has ended. At this time, the center point of the steel cage basically coincides with the center of the casing 1. At the same time, the steel cage placed above by the crane is in the upper position. Then, the stability of the upper steel cage is adjusted by the stabilizing mechanism to allow it to move downward stably, so that the upper and lower main bars are welded and processed to complete the docking. Then, the lifting block 2 is retracted into the second through groove 18 by the lifting member, and the inverted L-shaped block 17 is separated from the steel cage as a whole. The above operation is repeated to complete the placement of multiple sections of the steel cage. At the same time, the present invention sets the lifting block 2 at a position close to the horizontal side end of the inverted L-shaped block 17, and uses a pulling method to adjust the steel cage, which can effectively increase the scope of application of the device, and does not only work for pile foundation holes of a single size.The first servo motor 4 drives the first annular rack 44 to rotate through the second gear 45, and then drives the first lead screw 42 to rotate through the meshing of the first annular rack 44 and the first gear 43, so that the inverted L-shaped block 17 moves toward the center point of the casing 1, and at the same time, the push plate 21 will follow the inverted L-shaped block 17 to move, so that the sliding column 3 moves in the sliding groove 33. When the sliding column 3 moves to the through groove 34 position, the push plate 21 is subjected to an upward support force (provided by the spring of the support plate 39) when it is in the sliding groove 33, and then after the sliding column 3 reaches the through groove 34, the push plate 21 will be pushed upward by the support plate 39, and the sliding column 3 enters the upper slide groove 32 from the through groove 34, and the lifting block 2 extends. The upper slide groove 32 is formed, and the inverted L-shaped block 17 is moved forward. Part of the inverted L-shaped block 17 will be located in the steel cage. The crane will then lower the steel cage to place the welded stiffening hoop on the inverted L-shaped block 17. The inverted L-shaped block 17 will then shrink as a whole (the sliding column 3 will move in the upper slide groove 32 at this time). The lifting block 2 will be used to adjust the position of the steel cage. After the upper and lower steel cages are connected, the inverted L-shaped block 17 will move forward again to allow the sliding column 3 to move in the upper slide groove 32 until a group of inverted L-shaped blocks 17 move to the final point. The inverted L-shaped block 17 will then reverse and return to its original position. At this time, the sliding column 3 will pass through the first inclined surface 37 of the stopper 36 and enter the connection between the inclined groove 35 and the upper slide groove 32. When the L-shaped block 17 shrinks and returns to its original position again, the sliding column 3 will be pulled by the inclined surface of the stopper 36 and the inclined surface of the inclined groove 35, allowing the pushing plate 21 to move downward until the sliding column 3 enters the sliding groove 33 again, and then the sliding column 3 will move along the folding plate 38. Because the horizontal plate of the folding plate 38 just covers the opening of the through groove 34, the sliding column 3 can slide in the sliding groove 33 until the inverted L-shaped block 17 returns to its original position. At the same time, the lifting block 2 will also follow the movement of the inverted L-shaped block 17 in the second through groove 18 and then return to its original position without being blocked by the welded stiffening hoop. When the upper and lower steel cages need to be connected, the arc block 5 is moved up to the appropriate position as a whole, and then through The second threaded column 591 and the positioning hole 59 are limited, and then the limiting column 58 is pushed between the relative main bars, and then the position of the steel cage hoisted by the crane is manually adjusted. After the position is aligned with the processing position of the lower steel cage, the position of a pair of arc-shaped sliders 54 is adjusted to allow the limiting column 58 on it to contact the adjacent main bars, and then the screw cap on the first threaded column 56 is squeezed at the top of the arc block 5 to limit the limiting column 58 at this time. At this time, the upper steel cage can basically not rotate left and right, or offset as a whole (the arc block 5 is a group, not one), thereby ensuring that the upper steel cage can stably move down to the processing position, and at the same time, it can also ensure a stable state during docking processing. ;
