Description

Technical Field

[0001] The present invention relates to the technical field of construction of precast concrete piles, and particularly relates to a grooving device for precast concrete piles. Background Art

[0002] A precast concrete pile is a pile type structure with a hollow interior, which is made mainly of concrete and is a kind of pile foundation building material. It has the advantages of light self-weight, good vibration absorption performance, high economic benefits, etc. Due to its unique advantages, precast concrete piles are widely used in various civil engineering projects.

[0003] After the precast concrete pile is driven into the soil, grooves need to be opened on its inner wall for the purpose of pipeline laying. After some precast concrete piles are driven into the soil, concrete also needs to be poured inside them. To make the connection between the poured concrete and the pile body closer, grooves also need to be opened on its inner wall.

[0004] In the prior art, generally a guide rod is arranged at a position close to the inner wall inside the pile body, and a motor is slidably connected to the guide rod. The motor drives a grooving cutter head, and the longitudinal grooves are opened by lowering the motor. However, this grooving method has the following disadvantages:

[0005] Firstly, only one groove can be opened at a time. Since multiple grooves need to be evenly opened circumferentially inside the precast concrete pile, multiple guide rods need to be arranged when opening grooves at different positions, which results in low grooving efficiency and troublesome operation.

[0006] Secondly, when there are requirements for precast concrete piles with different diameters or for the grooving depth, it can only be achieved by adjusting the distance between the guide rod and the inner wall of the precast concrete pile, and the grooving depth cannot be flexibly adjusted before grooving.

[0007] Thirdly, the width of the opened groove is the same as the diameter of the grooving cutter head, and the grooving width cannot be adjusted according to needs. Summary of the Invention

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0052] AsFigures 1 - 15 As shown in the figure, the present invention has the following four specific embodiments. Embodiment 1

[0053] A grooving device for precast concrete piles, comprising a seat plate 1, a hanging box 2, a lifting device, a grooving device and an adjusting device;

[0054] The seat plate 1 is located directly above the precast concrete pile 100, and the precast concrete pile 100 is driven into the soil mass 200. The bottom of the seat plate 1 is fixedly connected with support legs 11, and the bottom of the outer wall of the support legs 11 is fixedly connected with anchor plates 12. Anchor rods 13 are inserted into the anchor plates 12, and the anchor rods 13 are nailed into the soil mass 200. The hanging box 2 is located below the seat plate 1, and the lifting device is used to drive the hanging box 2 to move vertically;

[0055] U-shaped frames 21 are fixedly connected to the inner walls of the side plates of the hanging box 2. A driving cylinder 22 is rotatably connected inside the side plates of the hanging box 2 and the U-shaped frames 21. A transmission shaft 23 is slidably connected in the driving cylinder 22. Transmission grooves 24 are evenly formed in the circumferential direction on the transmission shaft 23. Transmission bars 25 slidably connected with the transmission grooves 24 are fixedly connected to the inner wall of the driving cylinder 22. A first driven bevel gear 26 is fixedly connected to one end of the driving cylinder 22 close to the center of the hanging box 2. A grooving motor 27 is fixedly connected to the hanging box 2. The grooving motor 27 is provided with a first output shaft 28 vertically downward. A first driving bevel gear 29 meshing with the first driven bevel gear 26 is fixedly connected to the bottom of the first output shaft 28;

[0056] The grooving device includes an installation box 41 and a grooving cutter head 42; one side plate of the installation box 41 close to the hanging box 2 is rotatably connected with the transmission shaft 23. A sliding rod 43 is fixedly connected to one side of the installation box 41. A sliding sleeve 44 is fixedly connected inside the hanging box 2. The sliding rod 43 is slidably connected in the sliding sleeve 44. A first driving gear 45 is fixedly connected to one end of the transmission shaft 23 extending into the installation box 41. The grooving device further includes a first driven gear 46 meshing with the first driving gear 45. A cutter shaft 47 is fixedly connected to the center of the first driven gear 46. The grooving cutter head 42 is fixedly connected to the head of the cutter shaft 47;

[0057] The adjusting device is used to adjust the distance between the installation box 41 and the hanging box 2.

[0058] In this embodiment, as shown in the figure, the seat plate 1 is fixed directly above the precast concrete pile 100 through the anchor rod 13. The distance between the installation box 41 and the hanging box 2 is adjusted through the adjusting device, so as to adjust the depth at which the grooving cutter head 42 coincides with the side plate of the precast concrete pile 100, and this depth is the depth of the groove to be opened subsequently.

[0059] As Figures 3 - 4 and Figure 9 shown, when the grooving motor 27 works, it drives the first output shaft 28 and the first driving bevel gear 29 to rotate, and the first driven bevel gear 26 meshing therewith rotates, so as to drive the driving cylinder 22 to rotate. AsFigures 4 - 5 and Figures 9 - 10 As shown in Figures 9 - 10 , when the position of the installation box 41 is adjusted, the sliding rod 43 moves in the sliding sleeve 44 to guide the movement of the installation box 41, and the installation box 41 pulls the transmission shaft 23 to move. Under the action of the transmission groove 24 and the transmission strip 25, the driving cylinder 22 can drive the transmission shaft 23 to rotate.

[0060] The first driving gear 45 rotates with the transmission shaft 23, and the first driven gear 46 meshing with the first driving gear 45 rotates, so that the cutter shaft 47 and the grooving cutter head 42 rotate.

[0061] The lifting device drives the hanging box 2 to move downward, and the position where the grooving cutter head 42 coincides with the precast concrete pile 100 is cut off to form a groove. Multiple grooves can be opened simultaneously. After the groove opening is completed, the grooving motor 27 is turned off, and the lifting device drives the hanging box 2 to move upward and reset. Embodiment 2

[0062] A mounting cylinder 48 is rotatably connected inside the mounting box 41. An avoidance hole is opened at a position of the mounting cylinder 48 close to the transmission shaft 23. The cutter shaft 47 is rotatably connected in the mounting cylinder 48. There are two cutter shafts 47, and the two cutter shafts 47 are symmetrically arranged on both sides of the first driving gear 45. An outer ring of the mounting cylinder 48 is fixedly connected with a worm gear 49. A rotating shaft 410 is rotatably connected below the mounting box 41, and a worm 411 meshing with the worm gear 49 is fixedly connected to the rotating shaft 410. A first knob 412 is fixedly connected to the head of the rotating shaft 410.

[0063] Further, the lead angle of the worm 411 is smaller than the equivalent friction angle between the meshing teeth of the worm 411 and the worm gear 49.

[0064] Further, limiting blocks 413 are symmetrically and fixedly connected to an outer wall of the mounting cylinder 48, and arc-shaped limiting frames 414 are symmetrically and fixedly connected to an outer wall of a side plate of the mounting box 41 away from the hanging box 2. The limiting blocks 413 are slidably connected in the limiting frames 414.

[0065] Further, a scale line 415 is provided on an outer wall of a side plate of the mounting box 41 away from the hanging box 2, and a pointer 416 is fixedly connected to the mounting cylinder 48.

[0066] In this embodiment, in order to adjust the width of the grooving, the specific technical features of the grooving device are further disclosed in this embodiment, such as Figure 5 and Figures 10 - 11As shown in the figure, by turning the first knob 412, the rotating shaft 410 and the worm 411 can be driven to rotate. The worm wheel 49 meshing with the worm 411 rotates, so that the mounting cylinder 48 rotates. When the mounting cylinder 48 rotates, the cutter shaft 47 and the grooving cutter head 42 are driven to rotate, so that the vertically staggered positions of the two grooving cutter heads 42 can be adjusted. The center of the mounting cylinder 48 coincides with the center of the first driving gear 45. When the mounting cylinder 48 rotates, the first driven gear 46 is always kept in the meshing state with the first driving gear 45.

[0067] As Figure 12 shown in the figure, when the two grooving cutter heads 42 are vertically aligned, the width of the groove opened is equal to the width of the grooving cutter head 42, which is L1;

[0068] As Figure 13 shown in the figure, when the mounting cylinder 48 rotates, the two grooving cutter heads 42 rotate synchronously. When the limiting block 413 contacts the other side wall of the limiting groove, the vertically staggered degree of the two grooving cutter heads 42 is the largest. The distance between the mutually remote sides of the two grooving cutter heads 42 is the width of the groove opening. At this time, the width of the groove is the largest, which is L2.

[0069] Since the lead angle of the worm 411 is smaller than the equivalent friction angle between the meshing teeth of the worm 411 and the worm wheel 49, the worm wheel 49 and the worm 411 are self-locking, that is, the worm 411 can drive the worm wheel 49 to rotate while the worm wheel 49 cannot drive the worm 411 to rotate. After the mounting cylinder 48 rotates, during the grooving process, as long as the worm 411 is not driven to rotate artificially, the position of the mounting cylinder 48 remains unchanged, so that the width of the groove opening remains consistent.

[0070] The settings of the limiting block 413 and the limiting frame 414 can limit the mounting angle of the mounting cylinder 48 to prevent the vertically staggered degree of the two grooving cutter heads 42 from being too large and a gap occurring between them.

[0071] When adjusting the width of the groove opening, the rotation angle of the mounting cylinder 48 can be read through the reading of the pointer 416 on the scale line 415, so as to ensure that the widths of the grooves opened are consistent. Embodiment 3

[0072] The adjusting device includes a screw rod 51 and an adjusting seat 52; right-angle brackets 53 are fixedly connected to the positions of the left rear corner and the right front corner of the hanging box 2. The screw rod 51 is rotatably connected inside the side plates of the right-angle bracket 53. A second driven bevel gear 54 is fixedly connected to one end of the screw rod 51 located inside the right-angle bracket 53. The other end of the screw rod 51 is rotatably connected to the U-shaped frame 21. A track groove 55 is formed in the side plate of the hanging box 2 corresponding to the position of the screw rod 51. A track rod 56 is fixedly connected inside the track groove 55. The adjusting seat 52 meshes with the screw rod 51 and is slidably connected to the track rod 56. A connecting rod 57 is hinged between the adjusting seat 52 and the mounting box 41. A shaft rod 58 is rotatably connected to the center of the right-angle bracket 53. A second driving bevel gear 59 meshing with the second driven bevel gear 54 is fixedly connected to the shaft rod 58. A transmission wheel 510 is fixedly connected to the bottom of the shaft rod 58. The two transmission wheels 510 are linked by a belt 511. A second knob 512 is fixedly connected to the top of the shaft rod 58 at the left rear.

[0073] In this embodiment, the technical features of the adjusting device are disclosed, such as Figures 8 - 9 and Figure 14 As shown, by rotating the second knob 512, one of the shaft rods 58 can be driven to rotate. Under the action of the transmission wheels 510 and the belt 511, the two shaft rods 58 rotate synchronously. The second driving bevel gear 59 rotates synchronously with the shaft rod 58, and the second driven bevel gear 54 meshing with the second driving bevel gear 59 rotates. Then, the screw rods 51 rotate synchronously. The adjusting seat 52 meshes with the screw rod 51 and is slidably connected to the track rod 56. When the screw rod 51 rotates, it can drive the adjusting seat 52 to move. The adjusting seat 52 drives the mounting box 41 to move through the connecting rod 57, thereby adjusting the position of the grooving cutter head 42.

[0074] The helix directions of the thread grooves on the screw rods 51 are set such that when the screw rods 51 rotate, the mounting boxes 41 approach or move away from the hanging box 2 synchronously. Embodiment 4

[0075] The lifting device includes a threaded barrel 31 and a lifting motor 32; there are four threaded barrels 31 arranged in a rectangular array. The bottom of the threaded barrel 31 is fixedly connected to the hanging box 2. A threaded sleeve 33 is rotatably connected to the seat plate 1. The threaded barrel 31 is meshed in the threaded sleeve 33. A second driven gear 34 is fixedly connected to the outer wall of the threaded sleeve 33. A housing 35 is fixedly connected to the seat plate 1. The housing 35 covers the second driven gear 34 inside it. Through holes are formed in the top plate of the housing 35 corresponding to the positions of the threaded barrels 31. The lifting motor 32 is fixedly connected to the housing 35. The lifting motor 32 is provided with a second output shaft 36 vertically downward. A second driving gear 37 is fixedly connected to the bottom of the second output shaft 36. Each second driven gear 34 meshes with the second driving gear 37.

[0076] In this embodiment, the technical features of the lifting device are disclosed, such as Figure 3 , and Figures 6 - 7As shown in the figure, when the lifting motor 32 operates, it drives the second output shaft 36 and the second driving gear 37 to rotate. Each of the second driven gears 34 meshed therewith rotates, so that the threaded sleeve 33 rotates. Since the threaded barrel 31 does not rotate, when the threaded sleeve 33 rotates, it can drive the threaded barrel 31 to move vertically, thereby driving the hanging box 2 to move vertically.

[0077] As a further implementation manner of this embodiment, a spray pipe 61 is fixedly connected to the bottom of the threaded barrel 31. A support plate 62 is fixedly connected to the installation box 41. The spray pipe 61 is fixedly connected in the support plate 62. A spray head 63 facing the grooving cutter head 42 is fixedly connected to the head of the spray pipe 61. A water tank 64 is fixedly connected to the top of the threaded barrel 31. A water pump 65 is fixedly connected to the seat plate 1. The inlet and outlet of the water pump 65 are respectively fixedly connected with a water inlet pipe 66 and a water outlet pipe 67. The water inlet pipe 66 and the water outlet pipe 67 are flexible hoses, and the head of the water outlet pipe 67 is connected to the water tank 64.

[0078] In this implementation manner, as Figure 3 and Figure 7 shown in the figure, during the grooving process, the head of the water inlet pipe 66 is placed in an external water source. When the water pump 65 operates, water is transported to the water tank 64 through the water outlet pipe 67. The water is sprayed out successively through the threaded barrel 31, the spray pipe 61 and the spray head 63, and acts on the grooving cutter head 42. On the one hand, it cools the grooving cutter head 42, and on the other hand, it can also perform dust reduction treatment on the dust generated during grooving.

[0079] As a further implementation manner of this embodiment, a forward and reverse switch 71 and a control switch 72 are fixedly connected to the seat plate 1. It further includes an external power source 73. The grooving motor 27 and the water pump 65 form a parallel circuit, and this parallel circuit forms a current loop with the external power source 73 through the control switch 72. The lifting motor 32 forms a current loop with the external power source 73 through the forward and reverse switch 71.

[0080] In this implementation manner, as Figure 15 shown in the figure, during grooving, the control switch 72 is closed, and the grooving motor 27 and the water pump 65 operate. The rotation direction of the lifting motor 32 is controlled through the forward and reverse switch 71, so that the hanging box 2 and the grooving cutter head 42 descend.

[0081] After grooving is completed, the control switch 72 is disconnected, and the lifting motor 32 is controlled to reverse through the forward and reverse switch 71 to make the hanging box 2 rise and reset.

[0082] In this application, the grooving motor 27 is powered by a wire with sufficient reserved length. During the grooving process, the wire can be lowered along with the hanging box 2.

[0083] The working principle of the present invention is as follows:

[0084] In the initial state, the hanging box 2 and the grooving cutter head 42 are located above the concrete precast pile 100.

[0085] Drive each screw rod 51 to rotate synchronously through the second knob 512, thereby driving the adjustment seat 52 to move. The adjustment seat 52 drives the installation box 41 to move through the connecting rod 57, and adjusts the overlapping depth of the grooving cutter head 42 and the precast concrete pile 100. This depth is the depth of the grooved body to be opened.

[0086] Drive the worm 411 to rotate through the first knob 412. The worm 411 drives the worm wheel 49 and the installation cylinder 48 to rotate, thereby adjusting the degree of vertical staggering of the two grooving cutter heads 42 on the same side, and further adjusting the width of the grooving.
