Description

Technical Field

[0001] The present invention relates to the technical field of hoisting, and particularly relates to a hoisting device for hanger processing. Background Art

[0002] During the installation of stay cables, the beam-end winch is used to tow the stay cables from the bridge deck or other storage positions to the front end of the main beam or near the embedded pipe at the beam end, preparing for subsequent installation and tensioning. Before the installation of the beam-end winch, the tower crane is usually used to hoist the steel section of the tower-top hanger. Since the overall frame of the tower-top hanger is heavy and exceeds the lifting capacity of the tower crane, the single-group steel section is hoisted in pieces and assembled at the tower top.

[0003] A Chinese patent document with the publication number CN117486044B discloses an adjustable manipulator for hoisting large steel parts, including a sling part and a hoisting part. The lifting rope is connected to the sling part, and the hoisting part is used for clamping the H-shaped steel. The hoisting part includes a hoisting plate, a clamping plate and an electromagnet. When the hoisting part is combined with the H-shaped steel, the hoisting plate on the hoisting part can be freely placed at any position on the upper surface of the H-shaped steel, and the hoisting plate and the clamping plate can slide freely on the upper surface of the H-shaped steel for correction until the preset position is reached. After the two electromagnets are energized, they attract each other magnetically, driving the two clamping plates to tightly fit on the outer surface of the H-shaped steel, thereby fixing the steel section and the hoisting part together.

[0004] In the above technology, when hoisting the H-shaped steel, in order to ensure the balanced force when the H-shaped steel is lifted, when installing the hoisting part on the H-shaped steel, it is also necessary for workers to first find two preset positions on the H-shaped steel, and the two preset positions need to be symmetrically arranged with respect to the middle part of the H-shaped steel. Then, manually move the two hoisting parts to the predetermined positions respectively and then hoist. In this process, the process of manual positioning and manually adjusting the position of the hoisting part is rather troublesome. Summary of the Invention

[0005] The present invention provides a hoisting device for hanger processing, aiming to solve the technical problem that the process of manual positioning and manually adjusting the position of the hoisting part in the related technology is rather troublesome.

[0006] A hoisting device for hanger processing includes a winch device and a lifting rope. The upper end of the lifting rope is connected to the winch device, and further includes: Two sets of clamping devices. The clamping device includes a clamping plate slidably mounted on the H-shaped steel and a locking mechanism for locking the clamping plate to the H-shaped steel. The locking mechanism is connected to the lifting rope through a first auxiliary rope; A positioning device. The positioning device includes two hooks respectively clamped at the left and right ends of the H-shaped steel, a second auxiliary rope for connecting the hooks to the lifting rope, and a rope-releasing mechanism for taking in and releasing the second auxiliary rope. The upper end of the clamping plate is vertically and fixedly provided with an elastic telescopic rod, and the telescopic end of the elastic telescopic rod is hinged to the middle part of the second auxiliary rope. When the winding device winds up the lifting rope, the second auxiliary rope drives the upper end of the elastic telescopic rod to move during the gradual tensioning process, and then drives the clamping plate to move in the left-right direction. When the second auxiliary rope is tightened, the two clamping plates are respectively located at the quarter positions near the left and right ends of the H-shaped steel. Then, the rope releasing mechanism releases the rope. After the first auxiliary rope is gradually tightened, the locking mechanism locks.

[0007] The effect is as follows: By setting the hook and the elastic telescopic rod vertically installed on the clamping plate, after installing the hook, then installing the two clamping plates on the H-shaped steel. During the process of the second auxiliary rope being gradually tightened, since the elastic telescopic rod is vertical and fixedly arranged on the clamping plate, and the telescopic end of the elastic telescopic rod is hinged to the midpoint of the second auxiliary rope, the second auxiliary rope drives the clamping plate to move on the H-shaped steel through the elastic telescopic rod. When the second auxiliary rope is tightened, the two clamping plates are located at the quarter positions near the left and right ends of the H-shaped steel. At this time, when the H-shaped steel is lifted, since the positions of the two clamping plates are symmetrical and evenly distributed at the left and right ends of the H-shaped steel, it can ensure that the forces on the two lifting points on the H-shaped steel are balanced during the hoisting process. This design of force balance not only improves the safety of hoisting but also ensures the stability of the H-shaped steel during hoisting.

[0008] Preferably, the locking mechanism includes a locking plate slidably installed on the clamping plate in the up-down direction and a pressing component for pressing the locking plate against the H-shaped steel. Two connecting plates are installed at the lower end of the clamping plate, and the two connecting plates are respectively located on the front and back sides of the H-shaped steel. A limiting plate for abutting against the lower end face of the upper flange of the H-shaped steel is installed on the connecting plate.

[0009] Preferably, the pressing component includes a pressing block slidably installed on the clamping plate in the front-back direction and a driving member one for driving the pressing block to move. A first inclined surface is formed on the pressing block, and a second inclined surface for closely attaching to the first inclined surface is formed on the locking plate. After the rope releasing mechanism releases the rope, the driving member one drives the pressing block to move, so that the locking plate moves downward to abut against the H-shaped steel.

[0010] Preferably, the driving member one includes a first lead screw passing through the pressing block and a rotating rod rotatably installed on the clamping plate. The pressing block and the first lead screw are in threaded engagement. A one-way bearing is rotatably installed on the clamping plate, and the rotating rod is fixedly connected to the outer ring of the one-way bearing. One end of the first lead screw is fixedly connected to the outer ring of the one-way bearing through a first elastic member. A limiting component for fixing between the clamping plate and the inner ring of the one-way bearing is arranged on the clamping plate. The end of the rotating rod far from the one-way bearing is connected to the first auxiliary rope. When the first auxiliary rope is gradually tightened, it drives the rotating rod to rotate, and then drives the first lead screw to rotate through the first elastic member, so that the first inclined surface presses against the second inclined surface downward.

[0011] Preferably, the limiting component includes a bolt. An installation hole coaxial with the one-way bearing is formed on the clamping plate. When the bolt passes through the installation hole and the inner ring of the one-way bearing at the same time, the inner ring of the one-way bearing is fixed to the clamping plate.

[0012] Preferably, a first groove is formed on the inner wall of the installation hole. An elastic telescopic block is slidably installed on the bolt. When the bolt is inserted into the inner ring of the one-way bearing, the elastic telescopic block is clamped in the first groove.

[0013] Preferably, an elastic member is installed between the rotating rod and the clamping plate to reset the rotating rod in the reverse rotation direction.

[0014] The effect is that after the hoisting is completed, only by pulling out the bolt can the pressing block be reset.

[0015] Preferably, the second auxiliary rope includes an upper section and a lower section. The upper section is respectively connected to the lifting rope and the rope releasing mechanism, and the lower section is respectively connected to the hook and the rope releasing mechanism.

[0016] The effect is that by dividing the second auxiliary rope into upper and lower sections and arranging the rope releasing mechanism between the two sections of the second auxiliary rope, the rope releasing mechanism is located at the middle position of the second auxiliary rope during the gradual tensioning of the first auxiliary rope.

[0017] Preferably, the rope releasing mechanism includes a sleeve sleeved on the second auxiliary rope, a gear rotatably installed in the sleeve, and two racks sliding along the axial direction of the sleeve and meshing with the opposite sides of the gear respectively. The two racks are respectively connected to the upper section and the lower section of the second auxiliary rope. An elastic telescopic block is slidably installed on the rack. A second groove adapted to the elastic telescopic block is formed on the sleeve. An elastic member is installed between the rack and the sleeve to drive the rack to retract the second auxiliary rope into the sleeve.

[0018] The effect is that by the elastic telescopic block arranged on the rack, after the second auxiliary rope is tensioned, the first auxiliary rope can automatically bear the gravity of the H-shaped steel.

[0019] Preferably, the connecting plate is slidably installed on the clamping plate in the front-rear direction. A second driving member for driving the connecting plate to move is installed on the clamping plate. The limiting plate is slidably installed on the connecting plate in the up-down direction. A third driving member for driving the limiting plate to move is installed on the connecting plate.

[0020] The effect is that by providing the second driving member and the third driving member, H-shaped steels of various specifications can be adapted.

[0021] Adopting the above technical solutions, the beneficial effects of the present invention are as follows: 1. By setting a catch and an elastic telescopic rod vertically installed on the clamping plate, after the catch is installed, as the secondary rope two gradually tightens, the secondary rope two drives the clamping plate to move on the H-shaped steel through the elastic telescopic rod. When the secondary rope two is tightened, the two clamping plates are located at the quarter positions near the left and right ends of the H-shaped steel. At this time, during the lifting process of the H-shaped steel, the force balance of the two lifting points on the H-shaped steel is ensured.

[0022] 2. By setting a locking mechanism, after the secondary rope one is tightened, it can drive the lead screw one to rotate through the rotating rod, and then drive the abutting block to move. The movement of the abutting block presses the locking plate against the surface of the H-shaped steel, thereby realizing automatically locking the clamping plate and the limiting plate together with the H-shaped steel.

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0034] As Figure 1 shown, a hoisting device for H-shaped steel processing in an embodiment of the present invention includes a hoisting device (not shown in the figure), a suspension rope 1, two groups of clamping devices 2 and a positioning device 3. The upper end of the suspension rope 1 is connected to the hoisting device. The hoisting device is used for winding and unwinding the suspension rope 1. The two groups of clamping devices 2 are both installed on the H-shaped steel 4 and are used for clamping the H-shaped steel 4. The positioning device 3 is used for adjusting the positions of the two groups of clamping devices 2 on the H-shaped steel 4 so that the two groups of clamping devices 2 are respectively located at the quarter positions close to the left and right ends of the H-shaped steel 4, so that the H-shaped steel 4 is evenly stressed during hoisting.

[0035] When hoisting the H-shaped steel 4, the worker first installs the two groups of clamping devices 2 on the H-shaped steel 4, and then the worker installs the positioning device 3 at the left and right ends of the H-shaped steel 4. When the hoisting device winds the suspension rope 1, the positioning device 3 first positions the two groups of clamping devices 2 so that the two groups of clamping devices 2 are respectively located at the quarter positions close to the left and right ends of the H-shaped steel 4, and then the suspension rope 1 hoists the H-shaped steel 4 through the clamping devices 2.

[0036] As Figures 1-4 and Figure 9As shown in the figure, the clamping device 2 includes a clamping plate 21 and a locking mechanism. The clamping plate 21 is slidably mounted on the H-shaped steel 4 in the left-right direction. The locking mechanism is connected to the lifting rope 1 through the first auxiliary rope 5. The locking mechanism is used to lock the clamping plate 21 to the H-shaped steel 4 to prevent the clamping plate 21 from sliding on the H-shaped steel 4. When the two clamping plates 21 are respectively located at the quarter positions near the left and right ends of the H-shaped steel 4, during the process of the first auxiliary rope 5 rising and gradually tightening, the first auxiliary rope 5 causes the locking mechanism to lock the clamping plate 21 to the H-shaped steel 4.

[0037] As Figures 4-8 shown, the locking mechanism includes four locking plates 22, two connecting plates 23, two limiting plates 24 and a pressing component. Four first chutes 211 penetrating through the lower end are formed on the lower end surface of the clamping plate 21. The four first chutes 211 are respectively located near the four corners of the clamping plate 21. The four locking plates 22 are respectively slidably mounted in the four first chutes 211 in the up-down direction. The pressing component is used to press the locking plates 22 against the H-shaped steel 4. The first auxiliary rope 5 is used to connect the lifting rope 1 and the pressing component. A second chute 212 penetrating through the lower end and the front and rear ends is formed on the lower end of the clamping plate 21 in the front-rear direction. The second chute 212 is located between the left first chute 211 and the right first chute 211. The two connecting plates 23 are slidably mounted in the second chute 212 in the front-rear direction. A second driving member for driving the connecting plates 23 to move is arranged in the second chute 212. The two connecting plates 23 are respectively located on the front and rear sides of the H-shaped steel 4. A third chute 231 penetrating through the front and rear is formed on the connecting plate 23. The two limiting plates 24 are respectively slidably mounted in the third chutes 231 on the two connecting plates 23 in the up-down direction. The limiting plates 24 are used to abut against the lower end surface of the upper flange of the H-shaped steel 4. A third driving member for driving the limiting plates 24 to lift is arranged in the third chute 231. A plurality of rollers 25 are rotatably mounted on the lower end surface of the clamping plate 21 and the upper end surface of the limiting plate 24. The rotation axis of the roller 25 is arranged in the front-rear direction. The roller 25 is used to reduce the frictional damage caused to the surface of the H-shaped steel 4 by the clamping plate 21 and the limiting plate 24 when the clamping plate 21 moves on the H-shaped steel 4.

[0038] When installing the clamping plate 21 on the H-shaped steel 4, the second driving member first moves the two connecting plates 23 away from each other, so that the two limiting plates 24 are respectively located on the front and rear sides of the H-shaped steel 4. Then the clamping plate 21 is placed on the H-shaped steel 4. The second driving member makes the two connecting plates 23 approach each other, so that most of the limiting plates 24 are located directly below the upper flange of the H-shaped steel 4. Then the third driving member makes the limiting plates 24 move upward until the rollers 25 on the limiting plates 24 abut against the surface of the upper flange of the H-shaped steel 4. When the first auxiliary rope 5 rises and gradually tightens, the pressing component makes the locking plates 22 abut against the H-shaped steel 4, thereby fixing the clamping plate 21 to the H-shaped steel 4 together.

[0039] As Figures 4-8As shown, the tightening assembly includes two tightening blocks 26 and a first driving member 27. Above the first chute 211, a fourth chute 213 is provided, and the fourth chute 213 communicates with the upper ends of the four first chutes 211. The two tightening blocks 26 are slidably mounted in the fourth chute 213 in the front-back direction. The first driving member 27 is used to drive the tightening blocks 26 to move in the front-back direction. The first auxiliary rope 5 is used to connect the suspension rope 1 and the first driving member 27. A plurality of first inclined surfaces are provided on the lower end surface of the tightening block 26, and a plurality of second inclined surfaces for abutting against the first inclined surfaces are provided on the upper end surface of the locking plate 22. In the initial state, the first inclined surface abuts against the second inclined surface. When the first auxiliary rope 5 rises and gradually tightens, the first driving member 27 drives the two tightening blocks 26 to approach each other. At this time, since the first inclined surface abuts against the second inclined surface, when the two tightening blocks 26 approach each other, the second inclined surface is pushed by the first inclined surface, so that the locking plate 22 moves downward to abut against the H-shaped steel 4.

[0040] As Figures 4-8 shown, the first driving member 27 includes a first lead screw 271 and a rotating rod 272. The first lead screw 271 passes through the clamping plate 21 and the tightening block 26 at the same time. Two threads with opposite helix directions are provided on the first lead screw 271. The two tightening blocks 26 are respectively engaged with the two threads with opposite helix directions. A ring groove is provided on the first lead screw 271, and a ring platform adapted to the ring groove is installed on the clamping plate 21. The ring groove and the ring platform are used to prevent the first lead screw 271 from moving in the front-back direction on the clamping plate 21. Elastic members one are respectively installed at the front and rear ends of the first lead screw 271. The elastic member one is a first torsion spring 273. The first torsion spring 273 is fixedly connected to the first lead screw 271. One-way bearings 274 are respectively installed at the front and rear ends of the two first torsion springs 273, and the first torsion spring 273 is fixedly connected to the outer ring of the one-way bearing 274. The one-way bearing 274 is rotatably mounted on the clamping plate 21. A limiting assembly for fixing between the clamping plate 21 and the inner ring of the one-way bearing 274 is provided on the clamping plate 21. The rotating rod 272 is composed of two support rods and a connecting rod in a "concave" shape. A lifting lug is installed at the connecting part of the two support rods. The lower end of the first auxiliary rope 5 is connected to the lifting lug. The lower ends of the two support rods are rotatably mounted on the clamping plate 21. The lower ends of the two support rods are respectively sleeved on the outer rings of the two one-way bearings 274, and the outer ring of the one-way bearing 274 is fixedly connected to the support rod. An elastic member two is provided between the lower end of the support rod and the clamping plate 21. The elastic member two is a second torsion spring 275. In the initial state, the support rods are in an inclined state, and at this time, both lifting lugs are close to the middle part of the H-shaped steel 4.

[0041] During hoisting, the limit assembly fixes the connection between the clamping plate 21 and the inner ring of the one-way bearing 274. When the first auxiliary rope 5 is gradually tightened, the support rod is driven to rotate through the lifting lug, causing the two lifting lugs to move away from each other. When the support rod rotates, the outer ring of the one-way bearing 274 drives the first torsion spring 273 to rotate. At this time, the outer ring of the one-way bearing 274 rotates relative to the inner ring, and then the first torsion spring 273 drives the first lead screw 271 to rotate. When the first lead screw 271 rotates, it drives the two abutting blocks 26 to approach each other. When the two abutting blocks 26 approach each other, they push the second inclined surface through the first inclined surface, so that the locking plate 22 moves downward to abut against the H-shaped steel 4. After hoisting is completed, first release the fixation of the limit assembly between the clamping plate 21 and the inner ring of the one-way bearing 274, and then after the first auxiliary rope 5 is slack, the second torsion spring 275 drives the support rod to rotate in the reverse direction for reset. When the support rod rotates in the reverse direction, it drives the outer ring of the one-way bearing 274 to rotate in the reverse direction, and then drives the first lead screw 271 to reverse through the first torsion spring 273, so that the two abutting blocks 26 move away from each other, thereby releasing the fixation between the locking plate 22 and the H-shaped steel 4.

[0042] As Figures 6-8 shown, the limit assembly includes two pins 29. The pins 29 can be hexagonal prisms. Mounting holes 214 adapted to the hexagonal prisms are provided on the front and rear end faces of the clamping plate 21, and the front end of the mounting hole 214 on the front end face and the rear end of the mounting hole 214 on the rear end face both penetrate. The two hexagonal prisms are respectively slidably mounted in the two mounting holes 214 along the front-rear direction. A first groove 215 is provided on the inner wall of the mounting hole 214. An elastic telescopic block 210 is slidably mounted on the hexagonal prism. When the hexagonal prism is inserted into the inner ring of the one-way bearing 274, the elastic telescopic block 210 is clamped in the first groove 215, and the end of the hexagonal prism away from the one-way bearing 274 extends beyond the clamping plate 21. When the hexagonal prism passes through both the mounting hole 214 and the inner ring of the one-way bearing 274 at the same time, the inner ring of the one-way bearing 274 is fixed to the clamping plate 21.

[0043] As Figures 6-8 shown, the second driving member includes a second lead screw 216. The second lead screw 216 passes through the clamping plate 21 along the front-rear direction. A fifth groove 217 is provided at the upper end of the second groove 212. A convex platform is installed at the top of the connecting plate 23. The convex platform is slidably mounted in the fifth groove 217 along the front-rear direction, and the second lead screw 216 passes through the convex platform. Two sections of threads with opposite helix directions are provided on the second lead screw 216. The convex platforms on the two connecting plates 23 are respectively engaged with the two sections of threads. The front end of the second lead screw 216 extends beyond the front end face of the clamping plate 21. A first handle is installed at the front end of the second lead screw 216. When moving the connecting plate 23, turning the first handle drives the second lead screw 216 to rotate, and then the two connecting plates 23 approach or move away from each other.

[0044] As Figures 5-8As shown in the figure, the third driving member includes a third lead screw 28. The third lead screw 28 is vertically passed through the connecting plate 23 and the limiting plate 24 at the same time, and the third lead screw 28 is in threaded engagement with the limiting plate 24. The lower end of the third lead screw 28 extends beyond the lower end surface of the connecting plate 23, and a second handle is installed on the lower end surface of the third lead screw 28. When adjusting the height of the limiting plate 24, rotate the second handle to drive the third lead screw 28 to rotate, thereby adjusting the height of the limiting plate 24.

[0045] As Figures 1-3 shown, the positioning device 3 includes two hooks 31, an elastic telescopic rod 32 and two rope releasing mechanisms. During hoisting, the two hooks 31 are respectively clamped at the left and right ends of the H-shaped steel 4. The hook 31 and the hoisting rope 1 are connected by a second auxiliary rope 6. The lower end of the elastic telescopic rod 32 is fixedly installed on the clamping plate 21, and the elastic telescopic rod 32 is vertically arranged on the clamping plate 21. The telescopic end of the elastic telescopic rod 32 is hinged to the middle of the second auxiliary rope 6. When the hoisting device winds up the hoisting rope 1, the second auxiliary rope 6 drives the upper end of the elastic telescopic rod 32 to move during the gradual tensioning process, and further drives the clamping plate 21 to move in the left and right directions. When the second auxiliary rope 6 is tightened, the two clamping plates 21 are respectively located at the quarter positions close to the left and right ends of the H-shaped steel 4.

[0046] As Figure 2 、 Figure 3 and Figure 9 shown, the rope releasing mechanism includes a sleeve 35, a gear 36, a third elastic member 37 and two racks 33. The sleeve 35 is sleeved on the second auxiliary rope 6. The gear 36 is rotatably installed in the sleeve 35. The two racks 33 are slidably installed in the sleeve 35 along the axis direction of the sleeve 35, and the two racks 33 are respectively engaged with the opposite sides of the gear 36. The second auxiliary rope 6 is divided into an upper section 61 and a lower section 62. The upper and lower ends of the upper section 61 are respectively fixedly connected to the hoisting rope 1 and one of the racks 33. The upper and lower ends of the lower section 62 are respectively engaged with the hook 31 and the other rack 33. An elastic telescopic block two 34 is slidably installed on one of the racks 33 in the radial direction of the sleeve 35. A second groove adapted to the elastic telescopic block two 34 is provided on the sleeve 35. The third elastic member 37 is installed between the other rack 33 and the sleeve 35. The third elastic member 37 is a compression spring, and the compression spring is used to retract the rack 33 into the sleeve 35, thereby driving the second auxiliary rope 6 to be retracted into the sleeve 35. In the initial state, the elastic telescopic block two 34 is clamped in the second groove. When the second auxiliary rope 6 is tightened, as the hoisting rope 1 continues to rise, the force on the hook 31 gradually increases. When the elastic telescopic block two 34 is squeezed into the rack 33, the two racks 33 move away from each other. At this time, the compression spring is gradually compressed, and at the same time the first auxiliary rope 5 is gradually tightened. When the second auxiliary rope 6 is relaxed, the compression spring drives the two racks 33 to move closer to reset.

[0047] The specific working principle of the present invention: When hoisting the H-shaped steel 4, the staff first rotates the handle 1 to move the two connecting plates 23 away from each other until the two limiting plates 24 are respectively located on the front and rear sides of the H-shaped steel 4. Then, the clamping plate 21 is placed on the H-shaped steel 4, and the handle 1 is reversed to move the two connecting plates 23 closer to each other, so that most of the limiting plates 24 are directly below the upper flange of the H-shaped steel 4. Then, the handle 2 is rotated to move the limiting plate 24 upward until the roller 25 on the limiting plate 24 abuts against the surface of the upper flange of the H-shaped steel 4. After that, the two hooks 31 are respectively clamped at the left and right ends of the H-shaped steel 4. Then, the hoisting device is started to wind up the lifting rope 1. As the lifting rope 1 moves upward, the auxiliary rope 2 6 gradually tightens. During the process of the auxiliary rope 2 6 gradually tightening, the auxiliary rope 2 6 drives the clamping plate 21 to move on the H-shaped steel 4 through the elastic telescopic rod 32. When the auxiliary rope 2 6 is tightened, the two clamping plates 21 are located at the quarter position close to the left and right ends of the H-shaped steel 4. As the lifting rope 1 continues to rise, the force on the hook 31 gradually increases. After the elastic telescopic block 2 34 is squeezed into the rack 33, the auxiliary rope 1 5 begins to gradually tighten. When the auxiliary rope 1 5 gradually tightens, it drives the support rod to rotate through the lifting lug, so that the two lifting lugs move away from each other. When the support rod rotates, it drives the torsion spring 1 273 to rotate through the outer ring of the one-way bearing 274. At this time, the outer ring of the one-way bearing 274 rotates relative to the inner ring, and then the torsion spring 1 273 drives the lead screw 1 271 to rotate. When the lead screw 1 271 rotates, it drives the two abutting blocks 26 to move closer to each other. When the two abutting blocks 26 move closer to each other, they push the inclined surface 2 through the inclined surface 1, so that the locking plate 22 moves downward to abut against the H-shaped steel 4, and finally the clamping of the H-shaped steel 4 is completed.
