Description

Technical Field

[0001] The present invention relates to the technical field of bridge hoisting equipment, and in particular to a bridge hoisting equipment. Background Art

[0002] When building a bridge, prefabricated panels are usually placed between two piers and fixed to complete the installation of the bridge. The hoisting structure of the bridge erector is an important part of the bridge erector, responsible for the lifting of the bridge, and is also the main load-bearing component of the bridge erector. The traditional bridge erector has a lifting point at each end of the beam, and each lifting point is connected to a winch, which is a double-lifting point lifting operation driven by the winch. The double-lifting point lifting operation is unstable, and it is easy to cause a series of problems such as the beam twisting in the air, difficulty in positioning, and high force on the beam during the lifting process, which can easily cause damage to the beam.

[0003] A Chinese invention patent with an existing authorization announcement number of CN109112963B is entitled a bridge lifting equipment, whose main structure is a movable frame, the lower end of the frame is provided with walking wheels, the upper surface of the frame is provided with a working platform for conveying bridge plates, a conveying mechanism is diagonally provided on the working platform, one end of the conveying mechanism serves as a loading end of the bridge plate, and the other end is provided with a traction machine installed on the working platform for pulling the bridge plate to move on the conveying mechanism, a lifting frame for lifting the bridge plate is provided above the working platform, the lifting frame is located above one end of the traction machine and is provided with two first elevators, and a second elevator is installed above the other end, the front end of the bridge plate is lifted on the two first elevators, and the rear end is lifted on the second elevator, and is lifted and placed on the bridge pier.

[0004] The above technology limits the rising direction of the bridge plate by forming a surface with three lifting points on the same side of the bridge plate, so that it will not flip over randomly under the action of the three lifting points when rising, thereby ensuring the safety of the hanging beam. However, the above technology has the following technical problems: the lifting points are directly connected to the bridge plate. In order to ensure the connection strength and the tensile strength of the lifting point position, embedded parts are installed on the bridge plate for connection support, so that when the bridge is rising, the bridge is lifted by the embedded parts, and the connection position of the bridge and the embedded parts is deformed due to its own gravity, so that the embedded parts will damage the main body of the bridge, and the position of the lifting points cannot change with the length, width and thickness of the bridge plate itself, so that bridge plates of different sizes will be damaged to different degrees during lifting, which increases the installation difficulty of workers and reduces the lifting efficiency of the bridge. Summary of the invention

[0005] The present invention provides a bridge hoisting device, which ensures the completion and strength of the bridge plate body, facilitates workers to install bridge plates of different sizes, and improves the hoisting efficiency of the bridge plates.

[0006] The technical solution of the present invention is as follows: A bridge hoisting device comprises a gantry, a bridge plate transported and moved by the gantry, and moving wheels for moving and positioning the gantry as a whole; Two slide rails are fixedly connected to the upper side of the gantry and slide along the long side of the gantry. Two slide rails are slidably connected to the two slide rails and driven by a motor. Both ends of each slide are fixedly connected to a first winch, and the middle section of each slide is fixedly connected to a second winch. A clamping assembly for connecting bridge plates of different widths is connected between the lower ends of the ropes of the two first winches, and the lower end rope of the second winch is connected to the upper end of the clamping assembly.

[0007] Furthermore, the clamping assembly includes two clamping seats, each of which is fixedly connected to a clamping seat on its upper side, each of which is rotatably connected to a linkage plate, a pressure plate is hinged between the lower ends of the two linkage plates on the same side, and the lower side of the pressure plate abuts against the upper side of the bridge plate; A first transmission plate is hinged on the upper end of the linkage plate, and the first transmission plate is fixedly connected to the rope at the lower end of the second winch; The lower sides of the two clamping seats on the same side are connected with a telescopic component for changing the distance between the two clamping seats.

[0008] Furthermore, a coupling seat is fixedly connected to the center position of the upper side of the first transmission plate.

[0009] Furthermore, a receiving seat is fixedly connected to the pressure plate, a slide groove is provided on the receiving seat, and a plurality of positioning grooves inclined downwardly toward the adjacent linkage plate are provided on one side of the slide groove facing the adjacent linkage plate.

[0010] Further, the telescopic assembly includes two connecting blocks, each of which is fixedly connected to the lower side of the clamping seat, each connecting block is slidably connected with a clamping column, a reinforcing sleeve is threadedly connected between the two clamping columns, and one end of each clamping column away from the reinforcing sleeve is threadedly connected with a linkage sleeve, and each linkage sleeve is slidably connected to the connecting block; The bent surface of each positioning column is detachably fixedly connected to the rope at the lower end of the first hoist on each side.

[0011] Furthermore, each of the connecting blocks is provided with a limiting groove, the limiting groove is an open groove, and each of the locking columns abuts against an inner wall of each limiting groove.

[0012] Furthermore, each of the positioning seats is provided with a positioning groove, which is an upwardly open groove, and each of the linkage plates is rotatably connected with a bolt and nut, which abuts against the inner wall of the positioning groove.

[0013] The beneficial effects of the present invention are: The three-point lifting method at both ends of the bridge plate is used to ensure the stability of the bridge plate during the lifting process, and the sliding effect of the slide plate makes the three-point lifting at both ends can be used in conjunction with bridge plates of different lengths. The clamping assembly converts the gravity of the bridge plate itself into a clamping force, so that the clamping assembly and the bridge plate are firmly fixed together during the lifting process, ensuring the stability of the bridge plate during the lifting process. At the same time, the clamping assembly can be quickly installed and disassembled with bridge plates of different widths and thicknesses, eliminating the use of embedded parts, ensuring the completion and strength of the main body of the bridge plate, and facilitating workers to install bridge plates of different sizes, thereby improving the lifting efficiency of the bridge plate.

DETAILED DESCRIPTION

[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1 to Figure 6 As shown, this embodiment proposes a bridge hoisting device, including a gantry 11, a bridge plate 16 transported and moved by the gantry 11, and a moving wheel 17 for moving and positioning the gantry 11 as a whole; Two slide rails 12 sliding along the long side direction of the gantry 11 are fixedly connected to the upper side of the gantry 11, two slide plates 13 driven by motors are slidingly connected to the two slide rails 12, two first hoists 14 are respectively fixedly connected to the two ends of each slide plate 13, and each second hoist 15 is fixedly connected to the middle section of each slide plate 13; The three-point hoisting method at both ends of the bridge plate 16 ensures the stability of the bridge plate 16 during the hoisting process, and the sliding action of the slide plate 13 enables the three-point hoisting at both ends to be used in conjunction with bridge plates 16 of different lengths; The clamping assembly for connecting bridge plates 16 of different widths is connected between the lower ends of the ropes of the two first hoists 14, and the lower end rope of the second hoist 15 is connected to the upper end of the clamping assembly; The clamping assembly converts the gravity of the bridge plate 16 into a clamping force, so that the clamping assembly and the bridge plate 16 are firmly fixed together during the lifting process, thereby ensuring the stability of the bridge plate 16 during the lifting process. At the same time, the clamping assembly can be quickly installed and disassembled with bridge plates 16 of different widths and thicknesses, eliminating the use of embedded parts, ensuring the completion and strength of the main body of the bridge plate 16, and facilitating workers to install bridge plates 16 of different sizes, thereby improving the lifting efficiency of the bridge plate 16.

[0018] like Figure 1 to Figure 6 As shown, the clamping assembly includes two clamping seats 21, the upper side of each clamping seat 21 is fixedly connected to each clamping seat 22, each linkage plate 23 is rotatably connected to each clamping seat 22, and a pressure plate 24 is hinged between the lower ends of the two linkage plates 23 on the same side, and the lower side of the pressure plate 24 abuts against the upper side of the bridge plate 16; The upper end of the linkage plate 23 is hinged to the transmission plate 25, and the transmission plate 25 is fixedly connected to the lower end rope of the second hoist 15; The lower sides of the two clamping seats 21 on the same side are connected to a telescopic component for changing the distance between the two clamping seats 21; When the second winch 15 drives the transmission plate 25 to move upward, the pressure plates 24 on both sides will flip the linkage plate 23 towards the connecting seat 27, that is, drive the connection position of the linkage plate 23 and the receiving seat 28 to flip downward around the bolt nut 231, so that the pressure plate 24 presses the bridge plate 16 between the lower side of the clamping seat 21 and the pressure plate 24, and the downward movement of the pressure plate 24 is converted through the gravity of the bridge plate 16 itself, so when the bridge plate 16 is hoisted, the bridge plate 16 and the clamping assembly are not easy to fall off, ensuring the rapid installation of the bridge plate 16 by the clamping assembly, that is, reducing the difficulty of workers to install the position of the bridge plate 16 connecting the rope, and at the same time, through the telescopic assembly, the clamping assembly can be used in conjunction with bridge plates 16 of different widths, without the need to install embedded parts on the bridge plate 16, ensuring the strength and integrity of the bridge plate 16 body itself, and at the same time enabling bridge plates 16 of different sizes to be quickly put into the installation process, thereby improving the efficiency of hoisting the bridge plate 16.

[0019] like Figure 1~Figure 4 As shown, the upper center position of the transmission plate 25 is fixedly connected to the coupling seat 27; Workers can detachably fix the second hoist 15 by passing the rope at the lower end of the second hoist 15 through the coupling seat 27, so that the coupling seat 27 moves upward through the rope at the lower end of the second hoist 15, so that the force directions on both sides of the lower transmission plate 25 are the same.

[0020] like Figure 3~Figure 4 As shown, the receiving seat 28 is fixedly connected to the pressure plate 24, the slide groove 281 is provided on the receiving seat 28, and a plurality of positioning grooves 282 inclined downward toward the adjacent linkage plate 23 are provided on one side of the slide groove 281 toward the adjacent linkage plate 23; According to the different widths and thicknesses of the bridge plates 16, the lower end of the linkage plate 23 is adjusted to engage with which locking groove 282, and the downward flipping angle of the linkage plate 23 is adjusted, so that bridge plates 16 of different thicknesses can be limited and clamped by the clamping assembly.

[0021] like Figure 5~Figure 6 As shown, the telescopic assembly includes two connecting blocks 31, each connecting block 31 is fixedly connected to the lower side of the clamping seat 21, the clamping column 32 is slidably connected to the connecting block 31, the reinforcing sleeve 33 is threadedly connected between the two clamping columns 32, and one end of each clamping column 32 away from the reinforcing sleeve 33 is threadedly connected to the linkage sleeve 34, and each linkage sleeve 34 is slidably connected to the connecting block 31; The bending surface of each positioning column 32 is detachably fixedly connected to the rope at the lower end of the first hoist 14 on each side; When the width of the bridge plate 16 is different, the distance between the two clamping seats 21 will become larger, and the distance between the clamping posts 32 on both sides can be lengthened by relatively rotating the clamping posts 32 and the reinforcing sleeve 33, so that the clamping posts 32 can still be connected to the clamping seats 21 after the change, and the clamping assembly can be used in conjunction with bridge plates 16 of different widths through the telescopic assembly; In addition, the ropes at the lower ends of the two first winches 14 on the same side are detachably fixedly connected to the positioning columns 32 on both sides, so that the bridge plate 16 can be transported and moved upward without the need for embedded parts, thereby ensuring the strength and integrity of the main body of the bridge plate 16, and at the same time facilitating the removal of excess embedded parts after the bridge plate 16 is installed.

[0022] like Figure 5~Figure 6 As shown, the limiting groove 35 is provided on the connecting block 31, the limiting groove 35 is an open groove, and each of the positioning posts 32 abuts against the inner wall of each of the limiting grooves 35; Workers can align and install the positioning column 32 through the limiting groove 35 , which facilitates the workers' disassembly and assembly between the positioning column 32 and the connecting block 31 .

[0023] like Figure 3~Figure 4 As shown, the positioning groove 221 is provided on the positioning seat 22, and the positioning groove 221 is an upwardly opening groove, and each linkage plate 23 is rotatably connected with a bolt and nut 231, and the bolt and nut 231 abuts against the inner wall of the positioning groove 221; The linkage plate 23 equipped with bolts and nuts 231 can be removed or installed from the positioning seat 22 through the positioning groove 221, which facilitates the installation and transportation of the components. After the linkage plate 23 abuts against the innermost wall of the positioning groove 221, the nuts on the bolts and nuts 231 are tightened to further fix the position of the linkage plate 23. When the transmission plate 25 moves up, the lower end of the linkage plate 23 flips downward around the bolts and nuts 231, so that the pressure plate 24 presses the bridge plate 16. That is to say, through the gravity of the bridge plate 16 itself, when the transmission plate 25 moves up, the linkage plates 23 on both sides can completely press the bridge plate 16 through the pressure plate 24.

[0024] The principle of this embodiment is: The four corners of the bridge plate 16 are aligned and installed through the four clamping seats 21, and then the two clamping seats 21 on the width side of the bridge plate 16 are connected. The distance between the clamping posts 32 on both sides is adjusted by the relative rotation between the clamping posts 32 and the reinforcing sleeves 33. Then, the clamping posts 32 with the adjusted distance are connected to the connecting block 31 along the limiting grooves 35. Then, the linkage sleeves 34 are rotated to make the linkage sleeves 34 at both ends threadedly connected with each adjacent clamping post 32, and finally, each clamping post 32 is completely fixedly connected to the clamping seat 21. During this installation process, the rope with the loop can be put on the clamping post 32 before the linkage sleeve 34 is tightened, or the rope at the lower end of the first winch 14 can be fixedly connected with the clamping post 32 on the corresponding side through a specific rope knotting method after the linkage sleeve 34 is tightened. Then, the transmission plate 25 with the pressure plate 24 connects the two linkage plates 23 to the clamping seat 22 along the gap between the two clamping seats 21, and then, by comparing the distance between the pressure plate 24 and the upper side of the bridge plate 16, adjust which clamping groove 282 the linkage plate 23 is connected to. After the connection position is determined, tighten the nut on the bolt nut 231 so that the linkage plate 23 is limitedly clamped on the clamping seat 22, and then the rope at the lower end of the second winch 15 passes through the coupling seat 27 for connection; Then start the first hoist 14 and the second hoist 15, and keep all the connected ropes in a straight state. The operator confirms the speed of the two ends of the bridge plate 16 moving upward, and finally the bridge plate 16 is stably moved upward to the pier position for installation. Then, the components can be removed from the bridge plate 16. When the second winch 15 drives the transmission plate 25 to move upward, the pressure plates 24 on both sides will flip the linkage plate 23 towards the connecting seat 27, that is, drive the connection position of the linkage plate 23 and the receiving seat 28 to flip downward around the bolt nut 231, so that the pressure plate 24 presses the bridge plate 16 between the lower side of the clamping seat 21 and the pressure plate 24, and the downward movement of the pressure plate 24 is converted through the gravity of the bridge plate 16 itself, so when the bridge plate 16 is hoisted, the bridge plate 16 and the clamping assembly are not easy to fall off, ensuring the rapid installation of the bridge plate 16 by the clamping assembly, that is, reducing the difficulty of workers to install the position of the bridge plate 16 connecting the rope, and at the same time, through the telescopic assembly, the clamping assembly can be used in conjunction with bridge plates 16 of different widths, without the need to install embedded parts on the bridge plate 16, ensuring the strength and integrity of the bridge plate 16 body itself, and at the same time enabling bridge plates 16 of different sizes to be quickly put into the installation process, thereby improving the efficiency of hoisting the bridge plate 16.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
