Description

Technical Field

[0001] This invention relates to a bridge cutting component and a cutting robot, belonging to the field of concrete cutting and processing technology. Background Technology

[0002] In bridge demolition, it is crucial to meticulously follow a specific sequence to dismantle the bridge deck, piers, and other structures. Pier demolition often requires the use of wire saws to cut the piers for efficient operation. Traditionally, this involves drilling holes at the pier location to position the saw rope at the cutting point, and installing additional drive components at the horizontal cutting location for positioning and rope movement. Setting these components requires finding stable anchor points and ensuring proper traction. In horizontal cutting, it is easy to lose the anchor points, forcing the drive components to be placed on the ground. This not only leads to tilting in the cutting direction but also increases the saw rope length, exponentially increasing costs. Furthermore, long saw ropes are prone to bouncing due to the beaded surface, accelerating rope wear and tear and causing unstable rock fragments to fly, compromising safety. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bridge cutting component and a cutting robot, which is mainly used for the cutting and disassembly of bridge piers. It can effectively improve the safety and stability of the cutting work while eliminating the cumbersome installation and positioning methods.

[0004] To achieve the above objectives, the present invention employs the following technical solution: On one hand, the present invention provides a bridge cutting assembly, including a mounting frame, a saw blade connected to one side of the mounting frame, a wire wheel rotatably mounted on the mounting frame, and a driving device for driving the wire wheel to rotate. A wire groove is provided around the side wall of the saw blade, and a steel wire rope hooked to the wire wheel is slidably inserted in the wire groove. A plurality of eccentric beads are evenly spaced on the steel wire rope. The opening of the wire groove cross section is constricted. The eccentric beads include a sliding part slidably disposed in the wire groove and a hammering part disposed outside the wire groove. The upper surface of the hammering part is higher than the upper surface of the saw blade, and the lower surface of the hammering part is lower than the lower surface of the saw blade.

[0005] Specifically, the front end of the saw blade is an isosceles triangle with rounded corners, and the vertex angle formed by the extension lines of the saw blade edge is 25°~50°. A liquid supply groove is provided inside the saw blade and around its edge. A first liquid supply pipe connected to the liquid supply groove is installed at the rear end of the saw blade. The liquid supply groove is used to supply coolant into the saw kerf.

[0006] Specifically, the liquid supply tank and the wire groove are connected by multiple connecting grooves, and the multiple connecting grooves form multiple liquid supply ports of the directional wire groove inside the saw blade. The liquid outlet position of the liquid supply port can meet the requirement of passing through the central axis position of the wire rope.

[0007] Specifically, the upper or lower surface of the saw blade is provided with a seepage slit at a position corresponding to the liquid supply tank, and the first liquid supply pipe supplies coolant to the saw kerf through the seepage slit.

[0008] Specifically, a water supply plate is installed at the rear end of the saw blade, at the return position of the eccentric beads. The interior of the water supply plate is a hollow water tank. Multiple nozzles connected to the hollow water tank are installed on the water supply plate. The spray direction of the multiple nozzles is directed towards the return eccentric beads. A second liquid supply pipe for supplying cooling water to the hollow water tank is also installed on the water supply plate.

[0009] Specifically, the wire-catching groove of the wire reel gradually expands from the inside to the outside, and the narrowest part of the wire-catching groove of the wire reel is smaller than the diameter of the wire rope. Guide block assemblies are provided at both ends of the wire groove where the saw blade is located.

[0010] Specifically, a soundproof box is installed at the rear end of the saw blade, and a microphone array module is installed inside the soundproof box. Several pickup tubes are installed on the side of the soundproof box facing the saw blade, and each pickup tube points to the working position of the saw blade. Sound insulation cotton is installed on each pickup tube and the inner wall of the soundproof box.

[0011] Specifically, the mounting bracket is equipped with an encoder that can be connected to the shaft where the wire reel is located, and a speed detection module for detecting the linear speed of the wire rope is installed at the rear end of the saw blade. The speed detection module includes at least a detection sensor for detecting the number of eccentric beads passing through per unit time.

[0012] On the other hand, the present invention provides a bridge cutting robot that uses any of the above-mentioned cutting components and further includes a robotic arm. A servo rotation module for driving the rotation of the mounting frame is installed on the mounting frame. The movable end of the robotic arm is fixedly connected to the servo rotation module. The rotation axis of the servo rotation module is perpendicular to the plane of the saw blade.

[0013] Specifically, a water tank is installed on the mounting frame at a position away from the saw blade. The inlets of the first and second liquid supply pipes are both connected to the bottom of the water tank. A flow valve and an electromagnetic control valve are installed on the first and / or second liquid supply pipes. A main water supply pipe is also connected to the bottom of the water tank.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The bridge cutting assembly and cutting robot provided by this invention, through a special design of the saw blade, can form a groove on its edge for placing the saw rope. By setting the driven saw rope in the groove, the whole assembly can be combined with the saw blade to form a complete cutting structure. Compared with traditional chainsaws, this structure will not produce protrusions at the end that affect the cutting into the interior of the bridge pier. The effective utilization rate of the saw rope is greatly improved, which can effectively reduce the cost of the saw rope. The cutting process is more stable. The saw rope will not jump due to the restriction of the groove. There is no need to set additional opposing anchor points for the drive assembly. It is not only more efficient in operation and easier to control the cutting direction, but also helps to reduce construction costs and improve the safety of construction operations. This invention provides a coolant supply tank at the saw blade location, allowing coolant to be supplied to the kerf simultaneously during the sawing process. Compared to traditional methods, this allows the coolant to flow effectively into the kerf, avoiding significant waste of cooling solution and the difficulty in getting it into the kerf. This effectively suppresses dust, promotes chip removal, and ensures cooling during the sawing process. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0017] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0018] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1

[0019] This invention provides a bridge cutting assembly, primarily used for the cutting and disassembly of bridge piers. It effectively improves the safety and stability of the cutting process while eliminating cumbersome installation and positioning methods. To realize the structural function of the cutting assembly, the assembly includes a mounting frame 1, which can be referred to... Figure 1As shown, a saw blade 2 is connected to one side of the mounting frame 1. To achieve sufficient cutting depth, the saw blade 2 should have a relatively long lateral length, preferably made of high-strength, bending-resistant steel. To save on support stress at the connection points, it can be entirely hollowed out to reduce overall weight. To facilitate the sawing process, a wire wheel 5 is rotatably mounted on the mounting frame 1, and a drive device 6 (such as a servo motor) is also installed on the mounting frame 1 to drive the wire wheel 5. Simultaneously, a wire groove is provided around the side wall of the saw blade 2, and a steel wire rope 3 hooked onto the wire wheel 5 is slidably inserted into the groove. (Refer to...) Figure 5 as well as Figure 8 As shown, multiple eccentric beads 4 (made of diamond) are evenly spaced on the wire rope 3. When the pulley 5 is driven to rotate, the multiple eccentric beads 4 can swing at high speed, thereby using the high-speed abrasion of the cement by the multiple eccentric beads 4 to saw the pier structure. To prevent the wire rope 3 from disengaging from the groove, the groove cross-section is designed with an outward-facing opening in a constricted shape, as shown in the reference diagram. Figure 8 As shown, the eccentric bead 4 includes a sliding part slidably disposed within the groove and a hammering part disposed outside the groove. The sliding part is mainly used to form a stable connection with the wire rope 3 and to support the main structure to slide smoothly within the groove. The hammering part is used to achieve high-speed impact abrasion of materials such as concrete during high-speed rotation, thereby achieving a "cutting" effect on the pier structure. In order to ensure that the saw blade 2 can smoothly cut into the interior of the pier, the upper surface of the hammering part should be higher than the upper surface of the saw blade 2 and the lower surface of the hammering part should be lower than the lower surface of the saw blade 2. This allows the width of the kerf to be greater than the thickness of the saw blade 2 during impact abrasion, enabling the saw blade 2 to smoothly cut into the interior of the kerf and achieve deep cutting. In the above cutting operation, the mounting frame 1 can be configured as a horizontal feed drive, providing a feed distance according to the cutting depth. It is important to ensure that the moving direction is kept horizontal with the plane of the saw blade 2 to avoid jamming during cutting. The advantages of the aforementioned grooved converging design are as follows: During high-speed rotation of the wire saw, the heavier parts are easily displaced outwards by centrifugal force. Therefore, the eccentrically positioned diamond beads ensure that the hammering part remains stable and level with the saw blade 2 during high-speed movement. Consequently, the eccentric beads 4 are less likely to cause severe wear at the edge of the groove where the saw blade 2 is located, thus ensuring the overall service life of the structure. When using this component for cutting operations, there is no need for additional opposing anchor points. Because the saw rope's position is limited, it is less prone to jumping and causing unsafe factors such as flying stones. The saw rope length does not need to be excessive, effectively reducing the design cost of the saw rope (as the use of a harder diamond material as a wear material increases the overall design cost of the saw rope).

[0020] In some preferred embodiments of the bridge cutting assembly provided by this invention, considering the need to balance the thickness of the saw blade 2 and the support length for the saw rope, and to prevent excessive stress on the outer connection point of the saw blade 2 after design, which could easily cause the saw blade 2 to bend, the front end of the saw blade 2 can be configured as an isosceles triangle with rounded corners, while the middle part can still adopt a hollow design to reduce the overall weight. At this time, the apex angle formed by the extended edge lines of the saw blade 2 is 25°~50°, to avoid the saw rope from being blocked at small bends due to the angle being too small, and to avoid the saw blade 2 from being too large, which would increase the overall weight of the saw blade 2 by increasing the amount of ineffective area. Since the saw blade 2 will generate a lot of heat due to friction with the saw rope during high-speed cutting, in order to avoid the saw blade 2 deforming and wearing due to high-speed friction with the saw rope under heat, the saw blade 2 can be configured as follows: Inside the saw blade 2 and around its edge, there is a coolant supply groove 7. At this time, a first coolant supply pipe 9 connected to the coolant supply groove 7 is installed at the rear end of the saw blade 2. The coolant supply groove 7 is configured to supply coolant into the saw kerf. By supplying coolant into the saw kerf, the location of high-speed friction can be effectively cooled down. At the same time, the saw blade 2 itself will also have its temperature reduced due to the seepage design of the coolant supply groove 7, thus ensuring its service life. This coolant supply method can directly supply enough coolant into the inside of the saw kerf, thereby promoting the discharge of residual waste. Compared with the traditional method, after the annular saw kerf is formed, it is difficult for liquid to seep into the central cutting position through the saw kerf. Especially for the horizontal cutting action of bridge piers, the liquid cannot even accumulate inside the saw kerf by its own weight. This method achieves automatic coolant supply through the saw blade 2, which can not only cope with multi-angle cutting actions, but also ensure stable cooling of the wear and heat-generating surface inside the saw kerf according to the cutting method.

[0021] This invention provides a bridge cutting assembly. To directly cool the friction points between the wire groove and the steel wire rope 3, a liquid supply tank 7 and the wire groove can be connected via multiple connecting grooves. When the first liquid supply pipe 9 supplies coolant to the liquid supply tank 7, it can directly enter the interior of the wire groove through the connecting grooves, directly achieving cooling at the friction points. Excess coolant overflows through the wire groove, thereby cooling the inner side of the saw kerf at the friction point of the eccentric bead 4. To prevent the steel wire rope 3 from blocking the connecting grooves and preventing the liquid from smoothly entering the wire grooves, multiple connecting grooves are defined inside the saw blade 2 to form multiple liquid supply ports for the directed wire grooves. At this time, the liquid outlet position of the liquid supply port can satisfy the requirement of passing through the central axis position of the steel wire rope 3. Through the design of the special position, a reverse thrust can be generated on the steel wire rope 3 when hydraulic pressure is generated, preventing it from blocking the opening of the wire groove and the liquid outlet of the connecting groove. As another preferred embodiment, a seepage slit 8 can be provided on the upper or lower surface of the saw blade 2 at a position corresponding to the liquid supply groove 7. In this case, the first liquid supply pipe 9 supplies coolant to the saw kerf through the seepage slit 8. The seepage slit 8 naturally forms a coolant film on the upper and lower surfaces of the saw blade 2 through the action of the saw kerf, thereby directly achieving cooling of the inner side of the saw kerf. If the wear of the wire rope 3 in the groove is relatively severe, two sets of liquid supply grooves 7 can be set separately. One liquid supply groove 7 is configured to supply cooling water through the seepage slit 8, but the other liquid supply groove 7 can supply lubricating oil through the connecting groove. In this case, the outlet of the connecting groove should not cross the central axis of the wire rope 3. The sealing effect of the wire rope 3 itself can reduce the loss of the lubricating oil film. That is, the groove is filled with an oil film provided by lubricating oil, and the outside of the groove is coolant. In this case, although the wire rope 3 does not completely isolate the two media, it can effectively reduce the loss of lubricating oil and save its usage.

[0022] In a bridge cutting assembly provided by this invention, to prevent excessive dust and impurities from being introduced into the gaps of the wire reel 5 during the saw rope's return stroke, thus aggravating wear on the inner side of the wire reel 5, a water supply plate 13 can be installed at the rear end of the saw blade 2, located at the return stroke position of the eccentric bead 4. (See reference...) Figure 3 In the design shown, the interior of the water supply plate 13 is a hollow water tank, and multiple nozzles 14 connected to the hollow water tank are installed on the water supply plate 13. The spray direction of the multiple nozzles 14 is all directed towards the eccentric beads 4 returning from the return stroke. The water supply plate 13 is also equipped with a second liquid supply pipe 15 for supplying cooling water to the hollow water tank. That is, the multiple nozzles 14 are all supplied with high-pressure cleaning liquid by the second liquid supply pipe 15. During the return stroke of the eccentric beads 4 carrying impurities, the multiple nozzles 14 simultaneously rinse the surface of the eccentric beads 4, avoiding the limitation of the function of a single nozzle 14. Alternatively, the spray angles of the multiple nozzles 14 can be set to be different.

[0023] This invention provides a bridge cutting assembly. To ensure that the wire wheel 5 can accurately drive this irregular wire saw and provide a stable driving force, the wire groove of the wire wheel 5 can be set to gradually expand from the inside to the outside. At this time, the narrowest position of the wire groove of the wire wheel 5 is smaller than the diameter of the steel wire rope 3. When driving this wire saw, it is preferable that the steel wire rope 3 is embedded in the wire groove (the greater the tension of the steel wire rope 3, the greater the friction driving force provided), and the eccentric bead 4 can basically achieve the correct position. In order to ensure that the eccentric bead 4 falls accurately on the outside of the wire groove, guide block assemblies can be set at both ends of the wire groove where the saw blade 2 is located. The guide block assemblies are as close as possible to the edge of the wire wheel 5 to avoid the eccentric bead 4 being deflected due to the unstable rotation of the steel wire rope 3 caused by the excessive distance. The guide block assemblies guide the eccentric bead 4 to fall stably on the outside of the wire groove.

[0024] This invention provides a bridge cutting assembly. When using a saw blade 2 to cut bridge piers, the saw blade 2 needs to move in real time to follow the cutting process. Therefore, it is necessary to promptly determine whether to continue feeding to prevent the saw rope on the outside of the saw blade 2 from spinning idly for an extended period. To address this, a soundproof box 17 is installed at the rear end of the saw blade 2, and a microphone array module is installed inside the soundproof box 17. This microphone array module is used to identify sound signals at the wear location and to perform micro-feeding when the noise frequency decreases to ensure an efficient cutting process. To ensure the accuracy of sound pickup, several sound pickup tubes 18 are installed on the side of the soundproof box 17 facing the saw blade 2. The direction of the sound pickup tubes 18 can be referenced... Figure 3 As shown, each pickup tube 18 is positioned to point towards the working position of the saw blade 2. Sound-absorbing cotton is provided on the inner wall of each pickup tube 18 and the soundproof box 17 to prevent ambient noise from entering the soundproof box 17 and causing excessive interference. Alternatively, in another preferred embodiment, a bone conduction-like method can be used to pick up noise generated at the cutting position without the pickup tubes 18. In this case, sound-absorbing cotton should not be provided at the bottom of the soundproof box 17; the bottom surface can be directly and fixedly connected to the saw blade 2.

[0025] This invention provides a bridge cutting assembly. When the feed of the saw blade 2 is excessive, the resistance of the eccentric beads 4 increases, easily causing blockage. This manifests as the wire rope 3 easily slipping relative to the reel 5. Prolonged relative movement leads to friction and wear on the inner surface of the reel 5. Long-term abnormal temperature rise during operation can reduce durability. To achieve more precise control, an encoder that can connect to the shaft of the reel 5 can be installed on the mounting frame 1. A speed detection module for detecting the linear speed of the wire rope 3 can be installed at the rear end of the saw blade 2. The module includes at least a detection sensor 19 for detecting the number of eccentric beads 4 passing through per unit time. The detection sensor 19 can be used to measure the moving speed of the wire rope 3 by detecting the light-blocking signal of the eccentric beads 4 per unit time, or it can be used to detect the speed by setting a steel spacer between two adjacent eccentric beads 4 for magnetic induction detection. Other specific methods are not limited here. The encoder calculates whether the number of turns of the reel 5 matches the speed of the wire rope 3, thereby determining whether there is relative slippage between the two, thereby realizing the optimized control of the feed amount and ensuring that the saw blade 2 is always in the appropriate working position. Example 2

[0026] This invention provides a bridge cutting robot. To facilitate the efficient application of the above-mentioned cutting components in actual engineering cutting work, the robot can be configured to include any of the bridge cutting components in Embodiment 1. When cutting is required, the robot can be moved directly to the construction site and the cutting angle can be freely adjusted according to the cutting requirements. For this purpose, the configuration device also includes a robotic arm 20. A servo rotation module 21 for driving the rotation of the mounting frame 1 is installed on the mounting frame 1. At this time, the movable end of the robotic arm 20 is fixedly connected to the servo rotation module 21. The robotic arm 20 is used to adjust the approximate working position and the cutting direction. At this time, the rotation axis of the servo rotation module 21 is perpendicular to the plane of the saw blade 2. The servo rotation module 21 is used to stably control the feed amount of the saw blade 2 and to achieve cutting in the plane direction of the saw blade 2. When it is necessary to exit, if it encounters stone or sand particles blocking the cut, the servo rotation module 21 should be reciprocated and vibrated until it is completely out of the saw kerf.

[0027] This invention provides a bridge cutting robot. To avoid the complexity of water pipe installation, a water tank 12 can be installed on the mounting frame 1 at a position away from the saw blade 2. (Refer to...) Figure 1 and Figure 2As shown, the inlets of the first liquid supply pipe 9 and the second liquid supply pipe 15 are both connected to the bottom of the water tank 12. A flow valve 11 and a solenoid control valve 10 are installed on the first liquid supply pipe 9 and / or the second liquid supply pipe 15 to control the flow rate or the pressure of the water jet. A main water supply pipe 16 is also connected to the bottom of the water tank 12, supplying cooling water via a liquid pump. In addition to supplying water, the water tank 12 also serves to maintain the gravitational balance on both sides of the servo rotation module 21, preventing excessive weight on one side from affecting the stability of the rotation.

[0028] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
