Description

Technical Field

[0001] The invention relates to a bridge demolition construction device, in particular to a demolition device for piers. Background Art

[0002] With the continuous development of modern transportation infrastructure construction, bridges, as an important part of the transportation network, their demolition and reconstruction projects occupy a key position in social development and traffic safety. Many old bridges can no longer meet the needs of current traffic flow due to disrepair or inadequate design, and need to be demolished in a timely manner to ensure traffic safety. During the bridge demolition process, piers, as the main load-bearing structure of the bridge, often become difficult to demolish due to their large size, heavy weight, and complex shape. In order to ensure the safety and efficiency of the demolition operation, it is urgent to accurately cut and control the piers to avoid the piers from overturning during the cutting process and ensure the safety of construction workers and the surrounding environment.

[0003] Existing pier column cutting equipment includes diamond wire saws and hydraulic cutters, etc. These cutting equipment usually require a crane to cooperate with the cutting operation. The specific method is to fix the cutting tool on the pier column and control the balance of the pier column through the crane after the cutting is completed. This method relies on the assistance of large machinery and needs to ensure the stability of the cutting equipment before cutting and ensure that the pier column does not overturn during the cutting process.

[0004] However, the existing cutting equipment is often complex in structure when fixed on the pier, and the installation and disassembly process is cumbersome, making it difficult to achieve rapid positioning. In addition, the existing technology relies on large machinery to maintain the balance of the pier, and cannot independently prevent the pier from overturning after cutting, which increases the complexity of the operation. In addition, due to the limited space around the bridge pier, cranes and other large mechanical equipment occupy a large amount of construction space. Therefore, the existing pier splitting equipment can only perform a single split at a single time, and cannot perform multiple operations at the same time, resulting in low cutting efficiency, further delaying the construction progress. Therefore, it is urgent to propose a new pier removal device to solve the above problems, improve the pier cutting efficiency and ensure construction safety. Summary of the invention

Moreover, since the first fixing component and the second fixing component are connected by the connecting piece to form a rigid structure, a stable fixing device is formed during the construction process, effectively solving the problem of the cutting equipment relying on large machinery to maintain the balance of the pier column in the prior art, thereby achieving the technical effect of independently preventing the pier column from overturning without relying on large machinery, thereby improving the construction safety. Furthermore, since the dismantling device adopts a compact structural design, and through the coordinated work of the first fixing component and the second fixing component, the fixing and cutting operations of the pier column can be completed quickly and accurately in a narrow construction space, effectively solving the problem of only being able to perform a single-point cutting operation due to large machinery occupying a large amount of construction space in the prior art, thereby achieving the technical effect of simultaneous operation at multiple points in a limited space, thereby greatly improving the cutting efficiency of the pier column and shortening the construction progress.

[0040] The device for removing pier columns adopts the design of a limiting wheel group, and arranges the first limiting wheel and the second limiting wheel on the side of the first fixing component facing the second fixing component, and the wire groove is opened on the peripheral side of the limiting wheel. Therefore, the movement path of the wire saw can be accurately guided when the wire saw is working, and the problem of uneven cutting surface or inaccurate cutting position caused by offset in the wire saw cutting process in the prior art is effectively solved, thereby achieving high precision and high stability in the pier column ring cutting. In addition, the limiting wheel group is provided with a second limiting groove through the guide wheel to further limit the movement path of the wire saw and prevent the wire saw from deviating from the established cutting channel, effectively solving the problem that the wire saw is prone to offset when cutting around the pier column, thereby achieving more accurate ring cutting operation and improving construction efficiency and cutting quality.

[0050] like Figures 1 to 4As shown, a preferred embodiment of the present application provides a dismantling device for a pier column, comprising a first fixing assembly 100, a first positioning assembly 200, a second fixing assembly 300, a second positioning assembly 400, a fifth connecting member 500 and a wire saw 600, wherein the first fixing assembly 100 comprises a first embracing side 110, the first positioning assembly 200 is connected to the first fixing assembly 100, so as to adjust the posture of the first embracing side 110, the second fixing assembly 300 comprises a second embracing side 310, the second positioning assembly 400 comprises a fifth connecting member 500 and a wire saw 600, wherein the first fixing assembly 100 comprises a first embracing side 110, the first positioning assembly 200 is connected to the first fixing assembly 100, so as to adjust the posture of the first embracing side 110, the second fixing assembly 300 comprises a second embracing side 310, and the second positioning assembly 400 comprises a fifth connecting member 500 and a wire saw 600. 0 is connected to the second fixing assembly 300, so as to adjust the posture of the second embracing side 310, the fifth connecting member 500 includes a first end 510 and a second end 520, the first end 510 is connected to the first fixing assembly 100, and the second end 520 is connected to the second fixing assembly 300, so as to connect the first fixing member 120 and the second fixing assembly 300 through the fifth connecting member 500 to form a rigid structure, the wire saw 600 is movably connected to the demolition device, and the wire saw 600 is arranged between the first fixing assembly 100 and the second fixing assembly 300. When the demolition device is in a working state, the first engaging side 110 of the first fixing component 100 abuts against the outer surface of the pier under the action of the first positioning component 200 to fix the first fixing component 100 on the outside of the pier, and the second engaging side 310 of the second fixing component 300 abuts against the outer surface of the pier under the action of the second positioning component 400 to fix the second fixing component 300 on the outside of the pier, and both ends of the wire saw 600 are subjected to tension to make the wire saw 600 taut and abut against the pier, and when the demolition device is in a non-working state, the first engaging side 110 of the first fixing component 100 is separated from the outer surface of the pier under the action of the first positioning component 200, and the second engaging side 310 of the second fixing component 300 is separated from the outer surface of the pier under the action of the second positioning component 400.

[0051] The overall structure of the pier column removal device is composed of multiple components, mainly including a first fixing component 100, a second fixing component 300, a first positioning component 200, a second positioning component 400, a fifth connecting member 500 and a wire saw 600. The design of the overall structure can ensure the stability and accuracy of the pier column during the cutting process, and through the coordinated work of the first positioning component 200 and the second positioning component 400, the device can be quickly fixed and disassembled. The compact structure of the device can adapt to the operation requirements in a narrow construction space, improve the cutting efficiency, and avoid the complexity of relying on large-scale mechanical operations.

[0052] The structure, size, material, function and effect of the first fixing component 100 in this embodiment are the same as the structure, size, material, function and effect of the second fixing component 300 in this embodiment, and the structure, size, material, function and effect of the first positioning component 200 in this embodiment are the same as the structure, size, material, function and effect of the second positioning component 400 in this embodiment. Therefore, the following description will only describe the specific structure, size, material, function and effect of the first fixing component 100 and the first positioning component 200 in this embodiment.

[0053] Specifically, the contour shape of the first embracing side 110 on the first fixing component 100 observed from its own cross section should be the same as the contour shape of the pier observed from its own cross section. The two cross sections here refer to the plane passing through the first fixing component 100 and parallel to the first embracing side 110 and the plane passing through the pier and perpendicular to the axis of the pier. The pier has various forms, and the contour shape of the pier observed from its own cross section includes circular, square, polygonal, etc., such as Figure 1 As shown, the outline shape of the pier column observed from its own cross section is taken as a circle, and the outline shape of the first embracing side 110 observed from its own cross section is also a circle, that is, the first embracing side 110 is an annular surface, so that when the first fixing component 100 is sleeved outside the pier column, the first embracing surface 110 surrounds the circumference of the pier column to fix and limit the first fixing component 100. The second embracing side 310 on the second fixing component 300 is also the same as the first embracing side 110.

[0054] The materials of the first fixing assembly 100 and the second fixing assembly 300 should have sufficient strength and durability, and commonly used materials may be metal materials such as high-strength steel, stainless steel or aluminum alloy. These materials have advantages in corrosion resistance and structural rigidity, and can ensure that the first fixing assembly 100 and the second fixing assembly 300 do not deform during use, thereby maintaining a precise fixing effect.

[0055] The first positioning assembly 200 is movably mounted on the first fixing member 120, and the first positioning assembly 200 should have the function of adjusting the first embracing side 110, so that the first embracing side 110 abuts against the peripheral side of the pier when the removal device is in the working state, thereby fixing the first positioning assembly 200 on the pier. The second positioning assembly 400 is also the same as the first positioning assembly 200.

[0056] The first fixing component 100 and the second fixing component 300 play the role of surrounding and fixing the pier in the entire device. Through the adjustment of the first positioning component 200 and the second positioning component 400, the first embracing side 110 and the second embracing side 310 can be in close contact with the outer surface of the pier, ensuring the stability of the first fixing component 100 and the second fixing component 300 during the cutting process. In addition, with the cooperation of the fifth connecting member 500, the pier can be effectively prevented from tilting or displacing when being cut, thereby improving the cutting accuracy.

[0057] The fifth connecting member 500 is usually a straight rod or a frame structure, with two ends respectively connected to the first fixing assembly 100 and the second fixing assembly 300, so that the first fixing assembly 100, the fifth connecting member 500 and the second fixing assembly 300 are connected as a whole. The cross-sectional shape of the fifth connecting member 500 can be rectangular, circular or other geometric shapes to provide a stable connection. It should be noted that in order to prevent the pier from overturning during the cutting process, this overall structure also needs to have high rigidity and integrity. Therefore, the main structure of the first positioning assembly 200, the main structure of the second positioning assembly 400 and the main structure of the fifth connecting member 500 can be made of high-strength metal materials to ensure that the shape of the pier can be approximately maintained as a whole under the action of the above-mentioned overall structure after being cut.

[0058] The connection relationship between the fifth connecting member 500 and the first fixing assembly 100 and the second fixing assembly 300 includes a fixed connection and a detachable connection, wherein the fixed connection includes integral casting or later welding, and the detachable connection includes connection with fasteners such as bolts and buckles. In this embodiment, based on the connection strength and the convenience of disassembly and assembly, the bolt connection method can be selected to connect the two ends of the fifth connecting member 500 to the first fixing assembly 100 and the second fixing assembly 300 respectively. It should be noted that the number of the fifth connecting members 500 is at least greater than two, and each of the fifth connecting members 500 is installed around the first embracing side 110, and a gap is left between the side of the fifth connecting member 500 facing the first embracing side 110 and the first embracing side 110 to provide a passage space for the wire saw 600.

[0059] The wire saw 600 is a thin and long saw blade, and its material can be diamond-coated wire or other wear-resistant, high-hardness materials to ensure that it will not wear out quickly when cutting hard materials. The wire saw 600 is usually installed between the first fixing component 100 and the second fixing component 300, and its two ends will remain in tension during cutting. The function of the wire saw 600 is to complete the circular cutting operation of the pier column. Through the high-hardness material of the wire saw 600, the hard material outside the pier column can be effectively cut to ensure the efficiency and accuracy of the cutting process. The wire saw 600 can achieve precise circular cutting of the columnar member while avoiding the risk of material wear and breakage during the cutting process.

[0060] Further, in some embodiments, Figure 1 As shown, one end of the fifth connecting member 500 is connected to the second fixing component 300 by bolting, and the number of bolts at this end is at least two to prevent the fifth connecting member 500 from rotating relative to the second fixing component 300. The other end of the fifth connecting member 500 is rotatably connected to the first fixing component 100 through a bearing 800. Specifically, the inner ring of the bearing 800 is fixedly connected to the first fixing component 100 through a fastener, and the other end of the fifth connecting member 500 is fixedly connected to the outer ring of the bearing 800 so that the other end of the fifth connecting member 500 can rotate relative to the first fixing component 100, and limit blocks 900 are installed on the first fixing component 100 at positions on both sides of the fifth connecting member 500 to limit the angle range of relative rotation of the other end of the fifth connecting member 500 and the first fixing component 100.

[0061] In other embodiments, one end of the fifth connecting member 500 is connected to the second fixing component 300 by bolting, and the number of bolts at this end is at least two to prevent the fifth connecting member 500 from relative rotation with respect to the second fixing component 300. The other end of the fifth connecting member 500 is rotatably connected to the first fixing component 100 through a bearing 800. Specifically, the outer ring of the bearing 800 is fixedly connected to the first fixing component 100, and the other end of the fifth connecting member 500 is fixedly connected to the inner ring of the bearing 800 so that the other end of the fifth connecting member 500 can rotate relative to the first fixing component 100. In addition, limit blocks 900 are installed on the first fixing component 100 at positions on both sides of the fifth connecting member 500 to limit the angle range of relative rotation of the other end of the fifth connecting member 500 and the first fixing component 100.

[0062] As mentioned above, one end of the fifth connecting member 500 is connected to the first fixed component 100 through the bearing 800, wherein the main function of the bearing 800 is to reduce the friction between the first fixed component 100 and the fifth connecting member 500, and ensure that the removal device can rotate stably in the working state. When one end of the fifth connecting member 500 is rotatably connected to the first fixed component 100 through the bearing 800, the removal device can maintain a certain rotation ability during the cutting process, thereby adapting to the needs of the circumcision operation. If there is no bearing 800, the rotation of the first fixed component 100 relative to the second fixed component 300 may be hindered, resulting in increased friction and causing unsmooth operation. At the same time, the bearing 800 connection can keep the removal device stable while rotating, avoiding vibration or instability caused by excessive friction or other resistance, thereby improving the cutting accuracy and the safety of the device. The limit blocks 900 on both sides of the bearing 800 are used to limit the rotation angle to ensure that the cutting range is controllable. The fifth connecting member 500 is connected to the first fixed component 100 through the bearing 800. Through the combination of the bearing 800 and the limit blocks 900, the removal device can rotate smoothly within the set range. At the same time, the limit blocks 900 limit the rotation angle to avoid operational errors caused by excessive rotation and to avoid exceeding the designed range of motion, thereby improving safety and operational accuracy.

[0063] Furthermore, in some embodiments, the first fixing component 100 is generally composed of two substantially identical structural members spliced ​​together by a first positioning component 200, the first positioning component 200 is composed of a first connecting member 210 and a second connecting member 220, and the same is true for the second fixing component 300. The second fixing component 300 is spliced ​​together by a second positioning component 400, the second positioning component 400 is composed of a second connecting member 220, and the second positioning component 400 is composed of a third connecting member 410 and a fourth connecting member 420.

[0064] like Figure 1 and Figure 4As shown, the first fixing assembly 100 includes a first fixing member 120 and a second fixing member 130, which are the two structural members having substantially the same structure as mentioned above. One end of the first fixing member 120 is connected to one end of the second fixing member 130 via a first connecting member 210, and the other end of the first fixing member 120 is connected to the other end of the second fixing member 130 via a second connecting member 220, so that the opposite sides of the first fixing member 120 and the second fixing member 130 are combined to form the aforementioned first embracing side 110, wherein when the dismantling device is in a working state, the first fixing member 120 and the second fixing member 130 have a tendency to move relative to each other under the action of the first connecting member 210 and the second connecting member 220, so that the first embracing side 110 abuts against the outer surface of the pier to fix the first fixing assembly 100 on the pier. The second fixing assembly 300 includes a third fixing member 320 and a fourth fixing member 330. The third fixing member 320 and the fourth fixing member 330 are two substantially identical structural members as mentioned above. One end of the third fixing member 320 is connected to one end of the fourth fixing member 330 through a third connecting member 410, and the other end of the third fixing member 320 is connected to the other end of the fourth fixing member 330 through a fourth connecting member 420, so that the side surfaces of the third fixing member 320 and the fourth fixing member 330 are surrounded to form the aforementioned second embracing side 310. When the dismantling device is in the working state, the third fixing member 320 and the fourth fixing member 330 have a tendency to move relative to each other under the action of the third connecting member 410 and the fourth connecting member 420, so that the second embracing side 310 abuts against the outer surface of the pier column, so as to fix the second fixing assembly 300 on the pier column.

[0065] Furthermore, because the second fixing assembly 300 is completely identical to the first fixing assembly 100 , and the second positioning assembly 400 is completely identical to the first positioning assembly 200 , only the first fixing assembly 100 and the first positioning assembly 200 need to be described later.

[0066] In some embodiments, one end of the first fixing member 120 is hinged to one end of the second fixing member 130 through a first connecting member 210. In this case, the first connecting member 210 is a structure such as a hinge shaft or a hinge. The other end of the first fixing member 120 is connected to the other end of the second fixing member 130 through a second connecting member 220. In this case, the second connecting member 220 is a fastener such as a bolt that cooperates with a nut, so that the other end of the first fixing member 120 and the other end of the second fixing member 130 are simultaneously subjected to relative tensile forces, thereby achieving the first embracing side 110 abutting against the outer surface of the pier.

[0067] In other embodiments, one end of the first fixing member 120 and one end of the second fixing member 130 are connected through the first connecting member 210, and the other end of the first fixing member 120 and the other end of the second fixing member 130 are both connected through the second connecting member 220. At this time, the first connecting member 210 and the second connecting member 220 are both fasteners such as bolts that cooperate with nuts, and one end of the first fixing member 120 and one end of the second fixing member 130, as well as the other end of the first fixing member 120 and the other end of the second fixing member 130 are all subjected to relative tensile forces to force the first embracing side 110 to abut against the outer surface of the pier.

[0068] In order to expand the application scope of the dismantling device, in some embodiments, the dismantling device further includes a resisting assembly (not shown in the figure), the resisting assembly includes a first resisting member and a second resisting member, wherein the first resisting member includes a first resisting surface, the first resisting member is mounted on the first fixing assembly 100, and the first resisting surface is arranged toward the pier column, so as to abut against the outer surface of the pier column when the dismantling device is working, and the second resisting member includes a second resisting surface, the second resisting member is arranged on the second fixing assembly 300, and the second resisting surface is arranged toward the pier column, so as to abut against the outer surface of the pier column when the dismantling device is working. The resisting assembly is generally suitable for fixing the first fixing assembly 100 and the second fixing assembly 300 to the outer surface of the pier column when the outline size of the pier column observed from the cross section is smaller than the outline shape of the first embracing side 110 observed from the cross section, by abutting the outer surface of the pier column with the resisting assembly, the first fixing assembly 100 and the second fixing assembly 300 are fixed to the outer surface of the pier column.

[0069] Specifically, the second abutting member is the same as the first abutting member. The first abutting member includes a connecting rod and an abutting block. The abutting block is installed at one end of the connecting rod, and the connecting rod is connected to the first fixing assembly 100. The two parts can be threadedly connected, or the connecting rod can be connected to the first fixing assembly 100 through a nut adapted to the connecting rod. In addition, the connecting rod can move relative to the first fixing assembly 100 so that the abutting block abuts against the outer surface of the pier. At this time, the first abutting surface is the side of the abutting block facing the pier.

[0070] Furthermore, in order to improve the cutting accuracy and ensure the cutting quality, the removal device also includes a limiting wheel set 700, such as Figure 1 , Figure 2 and Figure 4 As shown, the limiting wheel group 700 is installed on the side of the first fixing component 100 facing the second fixing component 300, and the limiting wheel group 700 includes a first limiting wheel 710, a second limiting wheel 720 and a plurality of guide wheels 730, wherein the first limiting wheel 710 and the second limiting wheel 720, the peripheral side of the first limiting wheel 710 and the peripheral side of the second limiting wheel 720 are both provided with a first wire groove, when the demolition device is in a working state, the inner wall of the wire groove of the first limiting wheel 710 and the outer surface of the pier column are combined to form an entrance of the wire saw 600, and the inner wall of the wire groove of the second limiting wheel 720 and the outer surface of the pier column are combined to form an exit,

[0071] When the wire saw 600 is configured to enter the entrance at one end and go around the circumference of the pier column once before passing through the exit when the demolition device is in working condition. A plurality of guide wheels 730 are distributed along the circumference of the circumference of the first embracing side 110, and a second limiting groove is provided on the circumference of each guide wheel 730. When the demolition device is in working condition, the inner wall of the second limiting groove of each guide wheel 730 is combined with the outer surface of the pier column to form a limiting channel to limit the wire saw 600 in the limiting channel. It should be noted that the entrance, the limiting channel and the exit are connected to form an annular channel. When the demolition device is in working condition, the annular channel is arranged around the circumference of the pier column to provide a moving channel for the wire saw 600, and the movement of the wire saw 600 is limited within the annular channel, thereby ensuring the cutting accuracy.

[0072] Further, in order to improve the cutting accuracy, the removal device also includes a horizontal component 1000, such as Figure 1 and Figure 3 As shown, in some embodiments, the horizontal component 1000 is arranged on the second fixed component 300, and the horizontal component 1000 at least includes a first horizontal detector 1010, a second horizontal detector 1020 and a third horizontal detector 1030. The first horizontal detector 1010 is arranged on a side of the second fixed component 300 away from or toward the first fixed component 100 to detect the horizontality in a first direction, and the second horizontal detector 1020 is arranged on a side of the second fixed component 300 away from or toward the first fixed component 100 to detect the horizontality in a second direction. When the demolition device is in a working state, the line connecting the second horizontal detector 1020 and the first horizontal detector 1010 passes through the axis center line of the pier column, and the third horizontal detector 1030 The third level detector 1030 is arranged on the side of the second fixing component 300 away from or toward the first fixing component 100 to detect the horizontality of the third direction, and when the dismantling device is in working state, the angle between the line connecting the third level detector 1030 and the axis of the pier and the line connecting the second level detector 1020 and the axis of the pier is equal to the angle between the line connecting the third level detector 1030 and the axis of the pier and the line connecting the first level detector 1010 and the axis of the pier, wherein the first direction is perpendicular to the second direction, and the third direction is forty-five degrees with the first direction or the second direction.

[0073] Specifically, the first horizontal detector 1010, the second horizontal detector 1020, and the third horizontal detector 1030 can be selected as strip-shaped horizontal bubbles, and the first direction, the second direction, and the third direction are the moving directions of the air bubbles in the corresponding strip-shaped horizontal bubbles. In this embodiment, the first horizontal detector 1010, the second horizontal detector 1020, and the third horizontal detector 1030 are used to measure the deviation degree of the relative horizontal position, plumb position, and inclined position of the demolition device during installation and use, so as to further ensure the cutting accuracy of the wire saw 600.

[0074] In some embodiments, the removal device further includes a wear-resistant sheet. In this embodiment, the wear-resistant sheet is made of tetrafluoroethylene material, and the thickness of the wear-resistant sheet can be any value between 3 mm and 5 mm. The wear-resistant sheet is disposed on the side of the first fixing assembly 100 facing the second fixing assembly 300, so that the wire saw 600 is placed in direct contact with the side of the first fixing assembly 100 facing the second fixing assembly 300 during the cutting process, so as to avoid damage to the first fixing assembly 100.

[0075] In some embodiments, the first embracing side 110 on the first fixing component 100 and the second embracing side 310 on the second fixing component 300 are both installed with anti-skid pads. In this embodiment, the anti-skid pads take rubber anti-skid pads as an example. When the demolition device is in the working state, the anti-skid pads can fill the gaps between the first embracing side 110 and the surface of the pier and between the second embracing side 310 and the surface of the pier, thereby enhancing the connection strength between the first fixing component 100 and the second fixing component 300 and the pier, so as to prevent the first fixing component 100 and the second fixing component 300 from relative movement relative to the pier when the demolition device is in the working state.

[0076] The above contents described in this specification are merely examples of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, as long as they do not deviate from the contents of the present specification or exceed the scope defined by the claims, they shall all fall within the protection scope of the present invention.
