Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to an anti-overturning device for removing a middle partition wall. Background Art

[0002] With the development of construction technology, urban construction is gradually moving towards underground space, and some foundation pits are too large and too deep. In order to reduce the construction risk during the excavation of super-large and deep foundation pits, the design of the foundation pit usually considers the use of middle partition walls to separate them. After the construction of the underground structure is completed, the middle partition walls need to be removed. In the existing technology, the removal of the middle partition wall often adopts the method of link cutting, but during the cutting process, the continuous vibration can easily cause disturbances at the root of the middle partition wall, and even cracks, which can easily cause the collapse of the middle partition wall, posing a high safety risk. Summary of the invention

[0003] In view of this, the present invention discloses a middle partition wall removal anti-overturning device, which aims to solve the problem that during the middle partition wall removal process, the root of the middle partition wall is disturbed, which easily causes the middle partition wall to collapse.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] The cam is provided with a plurality of guide wheels, and the guide wheels are provided with a plurality of guide wheels at two ends, and the guide wheels are provided with a plurality of guide wheels at two ends.

[0006] In this scheme, a through groove is bored on the top plate, the middle partition wall is divided into several cutting areas, and a group of positioning holes is bored in each cutting area; the base is hoisted above the second row of cutting areas, and the rotating shaft is rotated to make the support plate parallel to the through groove to ensure that the diagonal support frame extends into the gap between the top plate and the middle partition wall; then the rotating shaft is rotated, and the rotating shaft drives the support plate and the clamping plate to clamp the top plate, and then the support plate and the clamping plate clamp the top plate and fix it by bolts; then the clamping structure on the diagonal support frame is connected and fixed to the positioning holes on the middle partition wall in the second row; then the lifting frame is moved down by the traction equipment to contact the middle partition wall in the first row of the first column, and then the positioning structures on both sides of the lifting frame are connected to the corresponding positioning holes on the middle partition wall, and after cutting it, the lifting frame and the cut middle partition wall are lifted to the top of the top plate by the traction equipment, and then the middle partition wall is transported to the feeding equipment on the side by the rotating seat.

[0007] This solution applies a certain supporting force to the middle partition wall being cut through the guide rod and the lifting frame to prevent the cut middle partition wall from swaying or falling over, thereby avoiding safety accidents. In addition, the top plate is used to provide supporting force to the support plate, and the support plate is then used to apply supporting force to both sides of the second row of middle partition walls through the diagonal support frame to prevent the middle partition wall from swaying during the cutting process, causing disturbance and cracking at the root of the middle partition wall, causing the middle partition wall to collapse, and causing safety accidents.

[0008] Furthermore, the diagonal brace frame includes a diagonal brace rod hinged to the end of the support plate, the end of the diagonal brace rod is coaxially slidably connected to an adjusting rod, and a latch is detachably connected between the diagonal brace rod and the adjusting rod; support rods are hinged on the side walls of the diagonal brace rod, and the ends of the diagonal brace rods are hinged to a sliding seat slidably connected to the bottom of the support plate, a spring accumulator is slidably arranged on the support plate, the output end of the spring accumulator is connected to the sliding seat, and a locking pin is detachably connected to the spring accumulator; a sliding groove is vertically opened on the sliding seat, and a sliding connection is slidably connected in the sliding groove There is a plug-in rod, and an elastic reset part is arranged between the plug-in rod and the slide slot, the side wall of the plug-in rod is arranged with a shear groove, the bottom of the slide slot is arranged with an electromagnet for adsorbing the plug-in rod, the sliding seat is arranged with a controller for controlling the opening and closing of the electromagnet, the spring accumulator is arranged with an infrared rangefinder for detecting the distance between the sliding seat and the spring accumulator, and the infrared rangefinder is connected to the controller; the support plate is arranged with a through hole that cooperates with the plug-in rod and the locking pin, and when the plug-in rod is inserted into the through hole, the shear groove is opposite to the contact surface between the support plate and the sliding seat.

[0009] In this solution, after the clamping plate and the support plate are clamped and fixed, the electromagnet is powered on separately, and the electromagnet absorbs the plug rod into the slide slot, and removes the locking pin and the latch, so that the support rod can swing with the diagonal support rod; slide and swing the adjustment rod so that the clamping structure is directly opposite to the positioning hole of the second column of the middle partition wall, and then connect and fix the clamping structure with the positioning hole, and then reset the locking pin and the latch, and cut off the power of the electromagnet, and the plug rod is inserted into the corresponding through hole under the action of the elastic reset member, and the diagonal support frame is used to provide a stable support force for the middle partition wall. Then, turn on the controller and the infrared rangefinder.

[0010] When the middle partition wall is disturbed and overturned, the middle partition wall drives the adjustment rod and the diagonal support rod to swing through the clamping structure, and the diagonal support rod drives the sliding seat to move. At this time, the plug-in rod breaks along the shear groove, causing the sliding seat to move relative to the spring accumulator, and the kinetic energy of the middle partition wall is accumulated in the spring accumulator. At this time, the infrared rangefinder detects that the distance between the sliding seat and the spring accumulator exceeds the predetermined range, and the controller controls the electromagnet to be energized, and the electromagnet adsorbs the plug-in rod. When the kinetic energy of the middle partition wall is consumed to a certain extent, the accumulated kinetic energy of the spring accumulator is released, driving the sliding seat to reset, and the sliding seat drives the diagonal support rod to reset through the support rod, thereby applying a supporting force to the middle partition wall to reset the middle partition wall; in this process, the infrared rangefinder detects that the distance between the sliding seat and the spring accumulator is restored to the predetermined range, and the controller controls the electromagnet to be de-energized, and the remaining plug-in rod is inserted into the corresponding through hole again under the action of the elastic reset member, forming a temporary support for the middle partition wall to prevent the middle partition wall from completely overturning.

[0011] Furthermore, the clamping structure includes a support hingedly arranged at the end of the adjusting rod, the support is slidably connected with a cylinder, the cylinder and the support are detachably connected with bolts, a plurality of groups of grooves are arranged along the radial side of the cylinder, embedded nails are slidably connected in the grooves, and elastic reset parts are also arranged between the embedded nails and the grooves, a hydraulic pushing structure is arranged in the cylinder, a pushing block for pushing the embedded nail is arranged at the end of the hydraulic pushing structure, and the end of the pushing block is arc-shaped.

[0012] When the clamping structure is facing the positioning hole, slide the cylinder to insert it into the positioning hole, and then fix the cylinder and the support with bolts; then drive the pushing block through the hydraulic pushing structure, and use the pushing block to squeeze the embedded nail to insert it into the middle partition wall, and then push the diagonal brace to push the middle partition wall to reset, the diagonal brace can maintain the connection strength with the positioning hole to prevent the diagonal brace from separating from the middle partition wall.

[0013] Further, the positioning structure includes a horizontally arranged positioning rod, the positioning rod is horizontally slidably connected to the lifting frame, and a positioning pin is detachably connected between the lifting frame and the positioning rod; a plurality of accommodating grooves are opened on the circumferential side of the positioning rod along its axis, a plurality of moving rods horizontally and perpendicular to the positioning rod are slidably connected in the accommodating grooves, and top support plates are arranged between adjacent moving rods, both ends of the top support plates are hinged with top support rods, the ends of the top support rods are hinged with corresponding moving rods, and torsion springs are arranged at the hinges; a connecting block is coaxially slidably connected to the positioning rod, a rotating block threadedly connected to the positioning rod is rotatably connected to the side wall of the connecting block, and a protrusion connected to the annular block is fixed on the moving rod near the end of the lifting frame in the accommodating groove.

[0028] In this solution, a through groove is bored on the top plate 2 to divide the middle partition wall 1 into several cutting areas, and a group of positioning holes 3 are bored in each cutting area; the base 4 is hoisted above the second row of cutting areas, and the rotating shaft 10 is rotated to make the support plate 12 parallel to the through groove to ensure that the diagonal support frame extends into the gap between the top plate 2 and the middle partition wall 1; then the rotating shaft 10 is rotated, and the rotating shaft 10 drives the support plate 12 and the clamping plate 11 to clamp the top plate 2, and then the support plate 12 and the clamping plate 11 are bolted to the top plate 2 clamped and fixed; then the clamping structure on the diagonal support frame is connected and fixed with the positioning hole 3 on the middle partition wall 1 in the second column; then the lifting frame 8 is moved down to contact with the middle partition wall 1 in the first column and the first row by the traction device 7, and then the positioning structures on both sides of the lifting frame 8 are connected with the corresponding positioning holes 3 on the middle partition wall 1, and then after cutting it, the lifting frame 8 and the cut middle partition wall 1 are lifted to the top of the top plate 2 by the traction device 7, and then the middle partition wall 1 is transported to the feeding device on the side by the rotating seat 5.

[0029] This solution applies a certain supporting force to the middle partition wall 1 being cut through the guide rod 9 and the lifting frame 8 to prevent the cut middle partition wall 1 from shaking left and right or falling over, thereby avoiding safety accidents. In addition, the top plate 2 is used to provide supporting force to the support plate 12, and the support plate 12 is then used to apply supporting force to both sides of the second row of middle partition walls 1 through the diagonal support frame to prevent the middle partition wall 1 from shaking during the cutting process, causing disturbance and cracking at the root of the middle partition wall 1, causing the middle partition wall 1 to collapse and causing safety accidents.

[0030] In this embodiment, the diagonal support frame includes a diagonal support rod 13 hinged at the end of the support plate 12, and the end of the diagonal support rod 13 is coaxially slidably connected with an adjusting rod 14, and a latch is detachably connected between the diagonal support rod 13 and the adjusting rod 14 (conventional technical means, so it is not drawn in the figure); the side walls of the diagonal support rod 13 are hinged with support rods 15, and the ends of the diagonal support rods 13 are hinged with sliding seats 16 slidably connected to the bottom of the support plate 12, and a spring accumulator 17 is slidably arranged on the support plate 12, and the output end of the spring accumulator 17 is connected to the sliding seat 16, and a locking pin is detachably connected to the spring accumulator 17; a sliding groove is vertically opened on the sliding seat 16, and a plug-in rod 18 is slidably connected in the sliding groove. An elastic reset member 25 is provided between the plug rod 18 and the slide slot, a shear groove 19 is provided on the side wall of the plug rod 18, an electromagnet 20 for adsorbing the plug rod 18 is provided at the bottom of the slide slot, a controller for controlling the opening and closing of the electromagnet 20 is provided on the sliding seat 16, an infrared rangefinder for detecting the distance between the sliding seat 16 and the spring accumulator 17 is provided on the spring accumulator 17, and the infrared rangefinder is connected to the controller; a through hole 21 cooperating with the plug rod 18 and the locking pin is provided on the support plate 12, and when the plug rod 18 is inserted into the through hole 21, the shear groove 19 is opposite to the contact surface between the support plate 12 and the sliding seat 16 (the infrared rangefinder and the controller are conventional technical means, so they are not drawn in the figure).

[0031] In this solution, after the clamping plate 11 and the support plate 12 are clamped and fixed, the electromagnet 20 is powered on separately, and the electromagnet 20 absorbs the plug rod 18 into the slide slot, and removes the locking pin and the latch, so that the support rod 15 can swing with the diagonal support rod 13; slide and swing the adjustment rod 14, so that the clamping structure is directly opposite to the positioning hole 3 of the second column of the middle partition wall 1, and then connect and fix the clamping structure with the positioning hole 3, and then reset the locking pin and the latch, and cut off the power of the electromagnet 20, and the plug rod 18 is inserted into the corresponding through hole 21 under the action of the elastic reset member 25, and the diagonal support frame is used to provide a stable support force for the middle partition wall 1. Then, turn on the controller and the infrared rangefinder.

[0032] When the middle partition wall 1 is disturbed and overturned, the middle partition wall 1 drives the adjusting rod 14 and the diagonal support rod 13 to swing through the clamping structure, and the diagonal support rod 13 drives the sliding seat 16 to move. At this time, the plug-in rod 18 breaks along the shear groove 19, causing the sliding seat 16 to move relative to the spring accumulator 17, and the kinetic energy of the middle partition wall 1 is accumulated in the spring accumulator 17. At this time, the infrared rangefinder detects that the distance between the sliding seat 16 and the spring accumulator 17 exceeds the predetermined range, and controls the electromagnet 20 to be energized through the controller, and the electromagnet 20 adsorbs the plug-in rod 18. When the kinetic energy of the middle partition wall 1 is consumed to a certain extent, the accumulated kinetic energy of the spring accumulator 17 is released, driving the sliding seat 16 to reset, and the sliding seat 16 drives the diagonal support rod 13 to reset through the support rod 15, thereby applying a supporting force to the middle partition wall 1 to reset the middle partition wall 1; during this process, the infrared rangefinder detects that the distance between the sliding seat 16 and the spring accumulator 17 is restored to a predetermined range, and the electromagnet 20 is powered off through the controller. The remaining part of the plug-in rod 18 is inserted into the corresponding through hole 21 again under the action of the elastic reset member 25, forming a temporary support for the middle partition wall 1 to prevent the middle partition wall 1 from completely overturning.

[0033] In this embodiment, the clamping structure includes a support 22 hingedly arranged at the end of the adjusting rod 14, and a cylinder 23 is slidably connected to the support 22. The cylinder 23 and the support 22 are detachably connected by bolts, and a plurality of groups of grooves are arranged along the radial side of the cylinder 23. Embedded nails 24 are slidably connected in the grooves, and elastic reset members 25 are also arranged between the embedded nails 24 and the grooves. A hydraulic pushing structure is arranged in the cylinder 23, and a pushing block 27 for pushing the embedded nail 24 is arranged at the end of the hydraulic pushing structure, and the end of the pushing block 27 is arc-shaped.

[0034] When the clamping structure is facing the positioning hole 3, slide the cylinder 23 to insert it into the positioning hole 3, and then fix the cylinder 23 and the support 22 by bolts; then drive the pushing block 27 by the hydraulic pushing structure, and use the pushing block 27 to squeeze the embedded nail 24 to make it inserted into the middle partition wall 1, and then when the diagonal brace frame pushes the middle partition wall 1 to reset, the diagonal brace frame can maintain the connection strength with the positioning hole 3 to prevent the diagonal brace frame from separating from the middle partition wall 1.

[0035] In this embodiment, the positioning structure includes a horizontally arranged positioning rod 28, which is horizontally slidably connected to the lifting frame 8, and a positioning pin is detachably connected between the lifting frame 8 and the positioning rod 28 (conventional technical means, so it is not drawn in the figure); a plurality of accommodating grooves are opened on the circumference of the positioning rod 28 along its axis, and a plurality of moving rods 29 horizontally and perpendicular to the positioning rod 28 are slidably connected in the accommodating grooves, and a top support plate 30 is arranged between adjacent moving rods 29, and top support rods 31 are hinged at both ends of the top support plate 30, and the ends of the top support rods 31 are hinged to the corresponding moving rods 29, and torsion springs are arranged at the hinges; a connecting block 33 is coaxially slidably connected to the positioning rod 28, and a rotating block 32 threadedly connected to the positioning rod 28 is rotatably connected to the side wall of the connecting block 33, and a protrusion connected to the annular block is fixed on the moving rod 29 near the end of the lifting frame 8 in the accommodating groove.

[0036] In this solution, after the lifting frame 8 clamps the middle partition wall 1, the positioning rod 28 is slid to be inserted into the corresponding positioning hole 3, and then the positioning rod 28 and the lifting frame 8 are locked by the positioning pin; the rotating block 32 is rotated forward, and the rotating block 32 drives the connecting block 33 to move toward the positioning hole 3, and the connecting block 33 pushes the moving rod 29 to move through the protrusion, so that the top support rod 31 swings outward, and then pushes the top support plate 30 to move relatively until the top support plate 30 fits against the inner wall of the positioning hole 3, thereby improving the connection stability between the positioning rod 28 and the positioning hole 3; this solution can not only meet the positioning holes 3 of different specifications, but also reduce the requirements for punching the positioning holes 3.

[0037] In this embodiment, an anti-shear rod 35 inclined toward the base 4 is provided on the circumference of the rotating shaft 10 to enhance the anti-shear capability of the rotating shaft 10 and prevent the rotating shaft 10 from breaking.

[0038] In this embodiment, a frosted layer is provided on the lifting frame 8 to reduce the wear caused by the contact between the lifting frame 8 and the middle partition wall 1 .

[0039] In this embodiment, a rubber cushion layer is provided on the supporting plate 30 , and the softness of the rubber cushion layer is used to enhance the friction between the supporting plate 30 and the inner wall of the positioning hole 3 , thereby reducing looseness.
