Description

Technical Field

[0001] The present invention belongs to the technical field of deep foundation pit support removal, and in particular relates to a deep foundation pit support removal auxiliary device and method. Background Art

[0002] Foundation pit dismantling refers to the process of dismantling the temporary internal support structure during the construction of the internal support structure of the deep foundation pit project as the construction of the underground structure is gradually completed.

[0003] When dismantling supports in a deep foundation pit, the support beams to be removed are usually first supported and fixed using brackets, and then the support beams are cut into sections using a rope saw. After cutting, they are transported by forklift.

[0004] When the inventor was dismantling the support, he found that the existing wire saws, when cutting the support beam, all used a drive motor set on the ground, and then connected the wire saw to the support beam at a certain distance above the ground and the output end of the drive motor. The wire saw was driven by the rotation of the drive motor to cut the support beam. This method resulted in a very high requirement on the length of the wire saw during cutting. When encountering a higher support beam, a longer wire saw was needed to cut it. Most wire saws are made of diamond rope, which is relatively expensive. A longer wire saw will greatly increase the overall cost. Moreover, when cutting, due to the characteristics of the structure, the wire saw can only cut the surface of the support beam. This method can easily lead to a decrease in the overall cutting efficiency.

[0005] Therefore, the existing structure and defects are studied and improved, and a deep foundation pit support dismantling auxiliary device and method are provided to achieve a more practical purpose. Summary of the Invention

[0014] Preferably, the first telescopic rod, the second telescopic rod, the third telescopic rod and the fourth telescopic rod are all electric hydraulic rods.

[0015] Preferably, the connecting plate is an electric hydraulic rod with a retractable length.

[0016] A deep foundation pit support removal auxiliary method, using the deep foundation pit support removal auxiliary device, includes the following steps:

[0017] S1 places the auxiliary plate on the support beam to be removed so that the auxiliary plate engages with one corner of the support beam;

[0018] S2 controls the first telescopic rod and the second telescopic rod to retract, so that the first extrusion plate and the second extrusion plate are squeezed and fixed to both sides of the support beam, so that the auxiliary plate is firmly fixed on the support beam;

[0019] S3 controls the adjustment plate and the driven plate to rotate through the driving mechanism, so that the driving wheel and the driven wheel respectively move to the ends outside the auxiliary plate, and then wraps the rope saw in a ring shape around the outside of the support beam, and passes the rope saw through the driving wheel and the driven wheel;

[0021] S5 As the adjusting plate and the driven plate rotate, the rope saw continuously cuts the center of the support beam.

In addition, this fitting design reduces the distance between the drive motor and the support beam, thereby effectively reducing the length of the rope saw and greatly reducing the cost.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Example 1, please refer to Figure 1 、 Figure 2 and Figure 3A deep foundation pit support dismantling auxiliary device includes an auxiliary plate 2 and a rope saw 1. The auxiliary plate 2 is L-shaped, and one end of the auxiliary plate 2 is provided with a fixedly connected first telescopic rod 3, and the end of the first telescopic rod 3 is provided with a fixedly connected first extrusion plate 31. The other end of the auxiliary plate 2 is provided with a fixedly connected second telescopic rod 4, and the end of the second telescopic rod 4 is provided with a fixedly connected second extrusion plate 41. One end of the auxiliary plate 2 is provided with a rotatable driving shaft 53, and a rotatably connected adjusting plate 51 is provided on the driving shaft 53. The extending end of the adjusting plate 51 is provided with a rotatably connected adjusting shaft 54, and the adjusting shaft 54 ​​is provided on the adjusting shaft A fixedly connected driving wheel is provided, and a synchronous chain 52 is provided between the adjusting shaft 54 ​​and the driving shaft 53. The other end of the auxiliary plate 2 is provided with a fixedly connected positioning shaft 63, and a rotatably connected driven plate 61 is provided on the positioning shaft 63. The extended end of the driven plate 61 is provided with a rotatably connected driven shaft 62, and a connected driven wheel 6 is provided on the driven shaft 62. The auxiliary plate 2 is provided with two groups of driving mechanisms 8 that respectively drive the corresponding adjusting plates 51 and the driven plates 61 to rotate. The rope saw 1 is annular, and the rope saw 1 passes through the driving wheel 5 and the driven wheel 6. The rotation of the driving wheel 5 drives the rope saw 1 to rotate.

[0040] The design of the first telescopic rod 3, the second telescopic rod 4, the first extrusion plate 31, and the second extrusion plate 41 enables the auxiliary plate 2 to be firmly fixed on the support beam, thereby ensuring the stability of the wire saw 1 during cutting;

[0041] The design of the auxiliary plate 2, the adjusting plate 51, the driven plate 61, the driving wheel 5 and the driven wheel 6 can realize the tensioning of the rope saw 1 by rotating the adjusting plate 51 and the driven plate 61, so that the rope saw 1 can synchronously cut the two ends of the support beam. This cutting method fully improves the contact area between the rope saw 1 and the support beam, which can greatly improve the overall cutting efficiency. In addition, this fitting design reduces the distance between the drive motor 7 and the support beam, thereby effectively reducing the length of the rope saw 1 and greatly reducing the cost.

[0042] See also Figure 1 、 Figure 2 and Figure 3In this embodiment, the drive mechanism 8 includes a fixed plate 81, a drive rack 82, and fixed teeth 83. The ends of the adjustment plate 51 and the driven plate 61 are both arc-shaped, and each is provided with a plurality of fixedly connected and distributed fixed teeth 83. There are two fixed plates 81, each fixed to the ends of the auxiliary plate 2. The drive racks 82 are slidably connected to the corresponding fixed plates 81 and mesh with the corresponding fixed teeth 83. The auxiliary plate 2 is also provided with two fixedly connected first hydraulic rods 84, the extended ends of which are fixedly connected to the corresponding drive racks 82. The rotation of the adjustment plate 51 and the driven plate 61 is controlled by the meshing of the drive racks 82 and the fixed teeth 83.

[0043] In this embodiment, a driving motor 7 is provided on one side of the auxiliary plate 2 , and an output end of the driving motor 7 is connected and fixed to the driving shaft 53 .

[0044] In this embodiment, the auxiliary plate 2 includes a first plate and a second plate, and the first plate and the second plate are rotatably connected via a hinge.

[0045] The auxiliary plate 2 adopts the design of the first plate and the second plate, so that when the auxiliary plate 2 is not needed, the first plate and the second plate can be rotated to merge from an L shape into an I shape, which reduces space occupation and facilitates storage and transportation.

[0046] Example 2 is the same as Example 1 and is not described here. The difference from Example 1 is: Figure 4 、 Figure 5 and Figure 6 , also includes a cutting alignment mechanism for the rope saw 1, the alignment mechanism includes an alignment plate 94 and an alignment wheel 9, the alignment plate 94 is L-shaped, and the alignment plate 94 is located at the diagonal position of the auxiliary plate 2, the alignment wheels 9 are four, and the alignment plate 94 and the auxiliary plate 2 are each provided with two symmetrically distributed slide grooves 91, a slider 96 that can move back and forth is provided in the slide groove 91, the slider 96 is provided with a fixed connection to the third telescopic rod 95, the alignment wheels 9 are respectively fixedly connected to the corresponding third telescopic rod 95, the adjusting plate 51 and the driven plate 61 are both electro-hydraulic push rods with retractable length, a tensioning groove 57 is provided on the adjusting plate 51, a tensioning block slidably connected is provided in the tensioning groove 57, and a tensioning spring 55 for driving the tensioning block to automatically restore its initial position is provided in the tensioning groove 57, the tensioning block is provided with a rotatably connected tensioning wheel 56, the synchronous chain 52 passes through the tensioning wheel 56, and a connecting plate 92 connected is provided between the alignment plate 94 and the first extrusion plate 31.

[0047] The addition of the alignment mechanism can ensure that the wire saw 1 cuts both ends of the support beam at the same time while ensuring that the cutting edges are on the same straight line. This ensures stable cutting, reduces unnecessary cutting, and effectively ensures the cutting of the support beam.

[0048] The addition of the alignment wheel 9 cooperates with the retractability of the adjusting plate 51 and the driven plate 61, so that before the wire saw 1 cuts, it can form a "mouth" shape through the alignment wheel 9, the driving wheel 5 and the driven wheel 6. In this way, when cutting, the wire saw 1 can cut the two corners of the support beam by extending and rotating the adjusting plate 51 and the driven plate 61 and cooperating with the synchronous movement of the alignment wheel 9. Since the position of the alignment wheel 9 and the auxiliary plate 2 are fixed, the alignment wheels 9 are flush. Therefore, the wire saw 1 and the two corners of the support beam are on the same plane at this time, thereby ensuring the neatness of the wire saw 1 cutting. As the wire saw 1 contacts the two corners of the support beam, the alignment wheel 9 continues to move, separating the alignment wheel 9 from the wire saw 1. Then, the wire saw 1 and the alignment wheel 9 are separated by contraction, so that the alignment wheel 9 will not affect the subsequent cutting of the wire saw 1.

[0049] The design of the tensioning wheel 56 and the tensioning spring 55 enables the driving wheel 5 to always maintain the stability of the connection of the synchronous chain 52 as the adjustment plate 51 extends.

[0050] In this embodiment, a fourth telescopic rod 93 is fixedly connected to the sliding groove 91 , and an extending end of the fourth telescopic rod 93 is fixedly connected to the sliding block 96 .

[0051] In this embodiment, the first telescopic rod 3 , the second telescopic rod 4 , the third telescopic rod 95 and the fourth telescopic rod 93 are all electric hydraulic rods.

[0052] In this embodiment, the connecting plate 92 is an electric hydraulic rod with a retractable length.

[0053] When this embodiment is used:

[0054] Before cutting, the auxiliary plate 2 is fixed to the support beam, the wire rope 1 is placed in a ring around the outside of the support beam, and the wire rope 1 is passed through the alignment wheel 9, the driving wheel 5 and the driven wheel 6. Then, the adjustment plate 51 and the driven plate 61 are extended so that the driving wheel 5 and the driven wheel 6 are located at the other two corners of the support beam. The wire rope 1 at both ends of the alignment wheel 9 is tilted by synchronously controlling the rotation of the adjustment plate 51 and the driven plate 61.

[0055] Then, the drive motor 7 is started to drive the active wheel 5 to rotate, and then the fourth telescopic rod 93 is controlled to retract, driving the alignment wheel 9 to move synchronously, so that the rope saw 1 contacts the corners of the support beam at the alignment wheel 9 respectively. At this time, the rope saw 1 cuts the corners of the support beam, and then the fourth telescopic rod 93 is continued to retract. Since the rope saw 1 contacts the corners, and the rope saw 1 at both ends of the alignment wheel 9 is inclined, as the fourth telescopic rod 93 continues to retract, the alignment wheel 9 gradually separates from the rope saw 1. When the alignment wheel 9 is completely separated from the rope saw 1, the third telescopic rod 95 is retracted so that the alignment wheel 9 and the rope saw 1 are not on the same plane. At this time, the continued movement of the rope saw 1 affects the alignment wheel 9, and the cutting alignment on both sides of the support beam is completed;

[0056] Then, while controlling the adjustment plate 51 and the driven plate 61 to rotate, control them to shrink synchronously, and then perform subsequent cutting.

[0057] A deep foundation pit support removal auxiliary method, using the deep foundation pit support removal auxiliary device, includes the following steps:

[0058] S1: Place the auxiliary plate 2 on the support beam to be removed so that the auxiliary plate 2 engages with a corner of the support beam;

[0059] S2 controls the first telescopic rod 3 and the second telescopic rod 4 to retract, so that the first extrusion plate 31 and the second extrusion plate 41 are squeezed and fixed to both sides of the support beam, so that the auxiliary plate 2 is firmly fixed on the support beam;

[0060] S3 controls the adjustment plate 51 and the driven plate 61 to rotate through the driving mechanism 8, so that the driving wheel and the driven wheel 6 respectively move to the ends outside the auxiliary plate 2, and then the rope saw 1 is wrapped around the outside of the support beam in a ring shape, and the rope saw 1 passes through the driving wheel 5 and the driven wheel 6;

[0061] S4 then drives the rope saw 1 to rotate through the synchronous chain 52 by the rotation of the drive shaft 53, and then drives the adjustment plate 51 and the driven plate 61 to rotate toward the center of the auxiliary plate 2 through the drive mechanism 8, so that the rope saw 1 is in a tensioned state, so that the rope saw 1 can synchronously cut the two ends of the support beam;

[0062] S5 As the adjusting plate 51 and the driven plate 61 rotate, the rope saw 1 continuously cuts the center of the support beam. When the adjusting plate 51 and the driven plate 61 rotate to the set angle, the rope saw 1 at one end of the auxiliary plate 2 cannot contact the support beam. At this time, the support beam at one end of the auxiliary plate 2 is cut. As the adjusting plate 51 and the driven plate 61 continue to rotate, the rope saw 1 can continue to cut the remaining uncut support beam until it is completely cut. At this time, the support beam is cut and the subsequent support removal operation can be carried out.
