Description

Technical Field

[0001] The invention belongs to the field of bridges, in particular to a bridge beam hoisting and transferring device. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to enable vehicles, pedestrians, etc. to pass smoothly. A bridge is generally composed of an upper structure, a lower structure, supports, and ancillary structures. The upper structure, also known as the span structure, is the main structure for crossing obstacles; the lower structure includes abutments, piers, and foundations.

[0003] The beam is the main component of the superstructure, which is generally an extra-long concrete strip. Traditional beams are large in size and mass, so during the transfer process, a gantry crane is generally used to lift the beam from the stack, transfer it to a transport vehicle, and finally use on-site lifting equipment to place the beam on the pier.

[0004] The gantry crane is generally connected to the surface of the beam through multiple steel cables, and the steel cables are removed after the movement is completed. The connection and removal process generally requires operators to operate, which is not only time-consuming and cumbersome, but also due to the influence of inertia and wind, the steel cables are prone to swing, which is not only difficult to control but also easily causes safety problems.

[0005] To this end, the present invention provides a bridge beam hoisting and transferring device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a bridge beam hoisting and transferring device described in the present invention comprises a gantry crane, the central moving end of the gantry crane is connected to a translation hoisting frame, both ends of the translation hoisting frame are fixedly connected to a suspension frame, the bottom of the suspension frame is connected to two parallel steel cables, the bottom of the steel cable is provided with a moving module, the moving module is used to move on the top surface of the concrete beam, the moving module is provided with a docking assembly, the docking assembly is used to dock the steel cable with the steel bar ring on the top surface of the concrete beam;

[0008] Through the setting of the moving module, when the gantry crane moves the translation lifting frame to the top of the concrete beam and keeps it parallel, the four steel cables are vertically downward, and the moving module can fit the bottom of the steel cable to the surface of the concrete beam, and at the same time drive the four steel cables to move to the four corners of the concrete beam respectively. After moving to the steel ring, the steel ring and the steel cable are docked with it through the docking assembly. During the movement, the gantry crane gradually lowers the translation lifting frame, so that the steel cable can extend to all sides while keeping it straight. After the connection is completed, the gantry crane pulls up the translation lifting frame, pulls up the concrete beam and transfers it. After the transfer is completed, the docking assembly is untied, and the gantry crane slowly lifts the translation lifting frame, and the moving assembly drives the bottom of the steel cable to move slowly to the center, so that the steel cable can be slowly centered, reducing the impact of inertia. Through this setting, the effect of mechanically connecting the steel cable and the concrete beam is achieved. The entire process does not require the operator to get close, reducing safety hazards and improving transfer efficiency.

[0009] Preferably, the moving module includes guide block one and guide block two, the bottom of the steel cable is connected to guide block one and guide block two, three electric wheels are installed on the bottom of guide block one and guide block two, the top surfaces of guide block one and guide block two are fixed with air ducts that penetrate to the bottom, and the inside of the air duct is connected with a negative pressure fan. When guide block one at the bottom of the steel cable contacts the concrete beam, the negative pressure fan in the air duct is started to generate negative pressure at the bottom of the air duct, thereby adsorbing guide block one and guide block two above the concrete beam. At this time, the guide block one and guide block two can be driven to move by the drive of the electric wheels, and finally move to above the steel ring.

[0010] Preferably, a metal ring is sleeved on the bottom of the steel cable, and the metal ring is fixedly connected to the node block. The bottom of the node block is fixedly connected to guide block one and guide block two. The node block is concave at one end facing the steel ring, and an infrared ranging module is provided at the concave part of the node block. When guide block one and guide block two are adsorbed and fixed, a ranging laser is emitted outwardly through the infrared ranging module. Since the top surface of the concrete beam is flat and has no protrusions, as the electric wheel drives guide block one and guide block two to rotate outward, when the measured distance value matches the predetermined value range, the direction can be determined, so that guide block one and guide block two can move in the correct direction. Moreover, since the distance is measured, the traveled distance can also be determined, thereby ensuring that guide block one and guide block two can move correctly to the steel ring.

[0011] Preferably, the side of the guide block 2 away from the guide block 1 is vertical and flat, and a magnet block is fixed to the side surface. In order to reduce the inertial swing of the steel cable during movement, after the connection between the steel cable and the steel ring is finally contacted, the two steel cables at one end are first centered to the center through the electric wheel, so that the two steel cables become vertical, and then the guide blocks 2 at the bottom of the two steel cables are brought closer to each other under the drive of the electric wheel. They are attached under the adsorption of the magnet block, and then the negative pressure is closed. Through this setting, the two steel cables are restrained from each other and will not swing excessively under the action of inertia or wind.

[0012] Preferably, a servo motor is fixedly connected to the bottom of the node block, and the outer side of the output end of the servo motor is fixedly connected to the infrared ranging module. Two receiving plates are arranged on the top surface of the concrete beam, and the two receiving plates are located directly below the suspension frame. When the steel cable is lowered onto the concrete beam at the beginning, the servo motor is started to drive the infrared ranging module to flip downward, so that the infrared ranging module can emit ranging laser vertically downward. When the laser is irradiated onto the receiving plate, the receiving plate can display the position information, and the steel cable is moved to the central position by moving the steel cable. At this time, the steel cable is lowered so that the steel cable is unfolded. Guide block 1 and guide block 2 only need to rotate outward a very small angle to find the position of the steel ring.

[0013] Preferably, the docking assembly includes a hydraulic rod, which passes through one side of guide block one and is fixedly connected to guide block one, and a steel rod is fixedly connected to the output end of the hydraulic rod. A docking hole is provided on the surface of guide block two. When guide block one and guide block two are moved to the outside of the steel bar ring, the hydraulic rod is started to push outward, and the steel rod is passed through the steel bar ring and combined with the docking hole, so that the concrete beam and the steel cable can be connected. Even if the steel rod is slightly bent, it will not affect the normal operation of the hydraulic rod.

[0014] Preferably, the guide block one and the guide block two are arranged in an open arc shape toward one end of the steel bar ring, and a blocking column is fixedly connected between the guide block one and the guide block two, which cooperates with the outward arc shape of the guide block one and the guide block two. When the guide block one and the guide block two are close to the steel bar ring, there is a large opening to receive the steel bar ring, thereby improving the fault tolerance during the connection process. The setting of the blocking column can block the steel bar ring, so that the steel bar ring will not pass through the guide block one and the guide block two, thereby ensuring that the steel rod can be inserted into the steel bar ring.

[0015] Preferably, a spiral tube is wound around the outer surface of the steel cable, and the spiral tube is made of elastic material. The inner side of the spiral tube is hollow. Water tanks are fixedly connected to both ends of the translational lifting frame. A transmission tube is connected between the water tank and the two spiral tubes at the same end. The transmission tube is located at the bottom of the water tank and is forked. The forked ends are connected to water pumps. When the steel cable is suspended in the air, the liquid in the water tank is pumped into the spiral tube through one of the water pumps. The filled spiral tube has stronger rigidity, which prevents the steel cable from bending at will, further reducing the swaying of the steel cable. Since the water tank is always in a semi-water state, the water inside can reduce the swaying of the translational lifting frame under the action of shaking. After the steel cable is fixed to the concrete beam, the water in the spiral tube is pumped back into the water tank through another water pump.

[0016] Preferably, a solenoid valve is fixedly connected to the bottom end of the spiral tube, and a plurality of blocking plates are fixedly connected to the middle of the spiral tube. The blocking plates are made of elastic material and have an elliptical hole in the middle of the blocking plates. The solenoid valve is provided to open the solenoid valve when water is injected into the spiral tube so that the water source can be quickly filled. At the same time, the setting of the blocking plates can prevent the water flow from directly filling the bottom, allowing the water source to gradually fill the gap from top to bottom. When the water pressure is high, the blocking plates will be opened to form a larger opening to allow the water source to flow downward, thereby reducing the problem of excessive water loss.

[0017] Preferably, the three electric wheels are arranged linearly on guide block one, the electric wheel located in the middle is responsible for driving forward, and the electric wheels located at both ends are responsible for adjusting the direction of guide block one. Through the arrangement of the three electric wheels, the steering of guide block one and guide block two is more stable and easy to operate.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. A bridge beam lifting and transferring device described in the present invention, through the setting of the moving module, when the gantry crane moves the translation lifting frame to the top of the concrete beam and keeps it parallel, the four steel cables are vertically downward, and the moving module can fit the bottom of the steel cable to the surface of the concrete beam, and at the same time drive the four steel cables to move to the four corners of the concrete beam respectively. After moving to the steel ring, the steel ring and the steel cable are connected with it through the docking assembly. During the movement, the gantry crane gradually lowers the translation lifting frame, so that the steel cable can extend to the surroundings while keeping it straight. After the connection is completed, the gantry crane pulls up the translation lifting frame, pulls up the concrete beam and transfers it. After the transfer is completed, the docking assembly is untied. At this time, the gantry crane slowly lifts up the translation lifting frame, and the moving assembly drives the bottom of the steel cable to move slowly toward the center, so that the steel cable can be slowly centered, reducing the influence of inertia. Through this arrangement, the effect of mechanically connecting the steel cable and the concrete beam is achieved. The whole process does not require the operator to get close, reducing safety hazards and improving transfer efficiency.

[0020] 2. The bridge beam lifting and transferring device described in the present invention, through the setting of the air duct, when the guide block 1 at the bottom of the steel cable contacts the concrete beam, the negative pressure fan in the air duct is started to generate negative pressure at the bottom of the air duct, thereby adsorbing the guide block 1 and the guide block 2 above the concrete beam. At this time, the guide block 1 and the guide block 2 can be driven by the electric wheel to move, and finally move to above the steel ring. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] like Figure 1 to Figure 2 As shown, a bridge beam lifting and transferring device according to an embodiment of the present invention comprises a gantry crane 1, a central moving end of the gantry crane 1 is connected to a translation lifting frame 3, both ends of the translation lifting frame 3 are fixedly connected to a suspension frame 8, the bottom of the suspension frame 8 is connected to two parallel steel cables 4, a moving module is arranged at the bottom of the steel cable 4, the moving module is used to move on the top surface of the concrete beam 2, a docking assembly is arranged in the moving module, and the docking assembly is used to dock the steel cable 4 with the steel bar ring 5 on the top surface of the concrete beam 2;

[0030] During operation, due to the large volume and mass of the conventional beam, the gantry crane 1 is generally used to lift the beam from the stacking place and then transfer it to the transport vehicle during the transfer process. The gantry crane 1 is generally connected to the surface of the beam through multiple steel cables 4, and the steel cables 4 are removed after the transfer. The connection and removal process generally requires the operator to operate, which is not only time-consuming and cumbersome, but also due to the inertia and wind force, the steel cables 4 are prone to swing, which is not only difficult to control, but also easy to cause safety problems;

[0031] After the gantry crane 1 has moved the translation lifting frame 3 to the top of the concrete beam 2 and kept it parallel, the four steel cables 4 are vertically downward, and the moving module can fit the bottom of the steel cables 4 to the surface of the concrete beam 2, and at the same time drive the four steel cables 4 to move to the four corners of the concrete beam 2 respectively, and after moving to the steel ring 5, the steel ring 5 and the steel cables 4 are connected with it through the docking assembly. During the movement, the gantry crane 1 gradually lowers the translation lifting frame 3, so that the steel cables 4 can extend to the surroundings while keeping them straight. After the connection is completed, the gantry crane 1 pulls up the translation lifting frame 3, pulls up the concrete beam 2 and transfers it. After the transfer is completed, the docking assembly is untied. At this time, the gantry crane 1 slowly lifts the translation lifting frame 3, and the moving assembly drives the bottom of the steel cables 4 to move slowly to the center, so that the steel cables 4 can be slowly centered, reducing the influence of inertia. Through this arrangement, the effect of mechanically connecting the steel cables 4 and the concrete beam 2 is achieved. The entire process does not require the operator to approach, reducing safety hazards and improving transfer efficiency.

[0032] like Figure 3 to Figure 4 As shown, the mobile module includes a guide block 15 and a guide block 16, the bottom of the steel cable 4 is connected to the guide block 15 and the guide block 16, three electric wheels 18 are installed at the bottom of the guide block 15 and the guide block 16, and the top surface of the guide block 15 and the guide block 16 is fixed with an air duct 12 that penetrates to the bottom, and the inside of the air duct 12 is connected to a negative pressure fan;

[0033] During operation, when the guide block 15 at the bottom of the steel cable 4 contacts the concrete beam 2, the negative pressure fan in the air duct 12 is started to generate negative pressure at the bottom of the air duct 12, thereby adsorbing the guide block 15 and the guide block 2 16 above the concrete beam 2. At this time, the guide block 15 and the guide block 2 16 can be driven by the electric wheel 18 to move, and finally move to above the steel ring 5.

[0034] like Figures 1 to 4 As shown, a metal ring is sleeved at the bottom of the steel cable 4, and the metal ring is fixedly connected to the node block 10. The bottom of the node block 10 is fixedly connected to the guide block 15 and the guide block 2 16. The node block 10 is concavely arranged at one end facing the steel ring 5, and an infrared ranging module 11 is arranged at the concave part of the node block 10;

[0035] During operation, after the guide block 1 15 and the guide block 2 16 are adsorbed and fixed, the infrared ranging module 11 emits a ranging laser outward. Since the top surface of the concrete beam 2 is flat and has no protrusions, as the electric wheel 18 drives the guide block 15 and the guide block 2 16 to rotate outward, when the measured distance value matches the predetermined value range, the direction can be determined, so that the guide block 15 and the guide block 2 16 can move in the correct direction. Since the distance is measured, the traveled distance can also be determined, ensuring that the guide block 15 and the guide block 2 16 can move correctly to the steel ring 5.

[0036] like Figure 3 to Figure 4 As shown, the side of the guide block 2 16 away from the guide block 1 15 is vertical and flat, and a magnet block is fixedly connected to the side surface;

[0037] During operation, in order to reduce the inertial swing of the steel cable 4 during movement, after the final contact between the steel cable 4 and the steel ring 5, the two steel cables 4 at one end are first centered toward the center through the electric wheel 18, so that the two steel cables 4 become vertical, and then the guide blocks 16 at the bottom of the two steel cables 4 are brought closer to each other under the drive of the electric wheel 18. They are attached under the adsorption of the magnetic block, and then the negative pressure is closed. Through this setting, the two steel cables 4 are restrained from each other and will not swing excessively under the action of inertia or wind.

[0038] like Figures 2 to 4 As shown, a servo motor is fixedly connected to the bottom of the node block 10, and the outer side of the output end of the servo motor is fixedly connected to the infrared ranging module 11. Two receiving plates are arranged on the top surface of the concrete beam 2, and the two receiving plates are located directly below the suspension bracket 8;

[0039] During operation, when the steel cable 4 is first lowered onto the concrete beam 2, the servo motor is started to drive the infrared ranging module 11 to flip downward, so that the infrared ranging module 11 can emit ranging laser vertically downward. When the laser is irradiated onto the receiving plate, the receiving plate can display the position information. By moving the steel cable 4, the steel cable 4 is moved to the central position, and the steel cable 4 is lowered at this time. In this way, the steel cable 4 is unfolded, and the guide block 1 15 and the guide block 2 16 only need to rotate outward at a very small angle to find the position of the steel ring 5.

[0040] like Figures 2 to 4 As shown, the docking assembly includes a hydraulic rod 13, which passes through one side of the guide block 15 and is fixed to the guide block 15, and a steel rod is fixed to the output end of the hydraulic rod 13, and a docking hole 14 is opened on the surface of the guide block 2 16;

[0041] During operation, after the guide block 15 and the guide block 2 16 move to the outside of the steel ring 5, the hydraulic rod 13 is started to push outward, and the steel rod passes through the steel ring 5 and is combined with the docking hole 14, so that the concrete beam 2 and the steel cable 4 can be connected. Even if the steel rod is slightly bent, it will not affect the normal operation of the hydraulic rod 13.

[0042] like Figures 2 to 4 As shown, the guide block 15 and the guide block 2 16 are arranged in an open arc shape toward one end of the reinforcing steel ring 5, and a blocking column 17 is fixedly connected between the guide block 15 and the guide block 2 16;

[0043] During operation, in conjunction with the outward arc setting of the guide block 15 and the guide block 2 16 , when the guide block 15 and the guide block 2 16 are close to the steel ring 5 , there is a large opening to receive the steel ring 5 , thereby improving the fault tolerance during the connection process. The setting of the blocking column 17 can block the steel ring 5 so that the steel ring 5 will not pass through the guide block 15 and the guide block 2 16 , thereby ensuring that the steel rod can be inserted into the steel ring 5 .

[0044] like Figures 3 to 5 As shown, the outer surface of the steel cable 4 is wound with a spiral tube 9, the spiral tube 9 is made of elastic material, the inner side of the spiral tube 9 is hollow, both ends of the translational lifting frame 3 are fixedly connected with a water storage tank 6, a transmission pipe 7 is connected between the water storage tank 6 and the two spiral tubes 9 at the same end, the transmission pipe 7 is located at the bottom of the water storage tank 6 and is bifurcated, and the bifurcated ends are connected to water pumps;

[0045] During operation, when the steel cable 4 is suspended in the air, the liquid in the water tank 6 is pumped into the spiral tube 9 through one of the water pumps. The filled spiral tube 9 has stronger rigidity, so that the steel cable 4 will not bend at will, and the swing of the steel cable 4 is further reduced. Moreover, since the water tank 6 is always in a semi-water state, the water inside can reduce the swing of the translational lifting frame 3 under the effect of shaking. After the steel cable 4 is fixed to the concrete beam 2, the water in the spiral tube 9 is pumped back into the water tank 6 through another water pump.

[0046] like Figures 3 to 5 As shown, the bottom end of the spiral tube 9 is fixedly connected with a solenoid valve 20, and the middle part of the spiral tube 9 is fixedly connected with a plurality of blocking sheets 19, the blocking sheets 19 are made of elastic material, and an elliptical hole is opened in the middle part of the blocking sheets 19;

[0047] During operation, the solenoid valve 20 is set to open the solenoid valve 20 when water is injected into the spiral tube 9, so that the water source can be quickly filled. At the same time, the setting of the blocking plate 19 can block the water flow from directly filling the bottom, allowing the water source to gradually fill the gap from top to bottom. When the water pressure is high, the blocking plate 19 will be opened to a larger opening to allow the water source to flow downward, thereby reducing the problem of excessive water loss.

[0048] like Figure 4 As shown, the three electric wheels 18 are arranged linearly on the guide block 15. The electric wheel 18 located in the middle is responsible for driving forward, and the electric wheels 18 located at both ends are responsible for adjusting the direction of the guide block 15. When working, the arrangement of the three electric wheels 18 makes the steering of the guide block 15 and the guide block 2 16 more stable and easy to operate.

[0049] After the gantry crane 1 has moved the translational hoisting frame 3 to the top of the concrete beam 2 and maintained it parallel, the four steel cables 4 are vertically downward, and the moving module can fit the bottom of the steel cables 4 to the surface of the concrete beam 2, and at the same time drive the four steel cables 4 to move to the four corners of the concrete beam 2 respectively, and after moving to the steel ring 5, the steel ring 5 and the steel cables 4 are connected with it through the docking assembly. During the movement, the gantry crane 1 gradually lowers the translational hoisting frame 3, so that the steel cables 4 can extend to the surroundings while keeping them straight. After the connection is completed, the gantry crane 1 pulls up the translational hoisting frame 3, pulls up the concrete beam 2 and transfers it. After the transfer is completed, the docking assembly is untied. At this time, the gantry crane 1 slowly lifts the translational hoisting frame 3, and the moving assembly drives the bottom of the steel cables 4 to move slowly to the center, so that the steel cables 4 can be slowly centered to reduce the influence of inertia. Through this setting, the effect of mechanically connecting the steel cables 4 and the concrete beam 2 is achieved. The whole process does not require the operator to get close, which reduces safety hazards and improves transfer efficiency.

[0050] When the guide block 15 at the bottom of the steel cable 4 contacts the concrete beam 2, the negative pressure fan in the air duct 12 is started to generate negative pressure at the bottom of the air duct 12, so that the guide block 15 and the guide block 2 16 are adsorbed on the top of the concrete beam 2. At this time, the guide block 15 and the guide block 2 16 can be driven by the electric wheel 18 to move, and finally move to the top of the steel ring 5;

[0051] After the guide block 15 and the guide block 2 16 are fixed by adsorption, the infrared distance measuring module 11 emits the distance measuring laser outward. Since the top surface of the concrete beam 2 is flat and has no protrusions, the electric wheel 18 drives the guide block 15 and the guide block 2 16 to rotate outward. When the measured distance value matches the predetermined value range, the direction can be determined, so that the guide block 15 and the guide block 2 16 can move in the correct direction. Since the distance is measured, the travel distance can also be determined, ensuring that the guide block 15 and the guide block 2 16 can move correctly to the steel ring 5.

[0052] In order to reduce the inertial swing during the movement of the steel cable 4, after the final contact between the steel cable 4 and the steel ring 5, the two steel cables 4 at one end are first centered to the center through the electric wheel 18, so that the two steel cables 4 become vertical, and then the guide blocks 16 at the bottom of the two steel cables 4 are brought closer to each other under the drive of the electric wheel 18. And they are attached under the adsorption of the magnetic block, and then the negative pressure is closed. Through this setting, the two steel cables 4 are restrained from each other and will not swing excessively under the action of inertia or wind.

[0053] When the steel cable 4 is first lowered onto the concrete beam 2, the servo motor is started to drive the infrared ranging module 11 to flip downward, so that the infrared ranging module 11 can emit ranging laser vertically downward. When the laser is irradiated onto the receiving plate, the receiving plate can display the position information. By moving the steel cable 4 to the central position, the steel cable 4 is lowered. In this way, the steel cable 4 is unfolded, and the guide block 1 15 and the guide block 2 16 only need to rotate outward at a small angle to find the position of the steel ring 5.

[0054] When the guide block 15 and the guide block 2 16 are moved to the outside of the steel ring 5, the hydraulic rod 13 is started to push outward, and the steel rod passes through the steel ring 5 and is connected with the docking hole 14, so that the concrete beam 2 and the steel cable 4 can be connected. Even if the steel rod is slightly bent, it will not affect the normal operation of the hydraulic rod 13.

[0055] Cooperating with the outward arc setting of the guide block 15 and the guide block 2 16, when the guide block 15 and the guide block 2 16 are close to the steel ring 5, there is a large opening to receive the steel ring 5, thereby improving the fault tolerance during the connection process, and the setting of the blocking column 17 can block the steel ring 5, so that the steel ring 5 will not pass through the guide block 15 and the guide block 2 16, thereby ensuring that the steel rod can be inserted into the steel ring 5;

[0056] When the steel cable 4 is suspended in the air, the liquid in the water storage tank 6 is pumped into the spiral tube 9 through one of the water pumps. The filled spiral tube 9 has stronger rigidity, so that the steel cable 4 will not bend at will, and the swing of the steel cable 4 is further reduced. Since the water storage tank 6 is always in a semi-water state, the water inside can reduce the swing of the translational lifting frame 3 under the action of shaking. When the steel cable 4 is fixed to the concrete beam 2, the water in the spiral tube 9 is pumped back into the water storage tank 6 through another water pump.

[0057] The electromagnetic valve 20 is used to open the electromagnetic valve 20 when water is injected into the spiral tube 9, so that the water source can be quickly filled. At the same time, the blocking piece 19 can prevent the water from directly filling the bottom, so that the water source gradually fills the gap from top to bottom. When the water pressure is high, the blocking piece 19 is opened to a larger opening to allow the water source to flow down, thereby reducing the problem of excessive loss of water source;

[0058] Through the arrangement of the three electric wheels 18, the steering of the guide block 1 15 and the guide block 2 16 is more stable and easy to operate.
