Description

Technical Field

[0001] The invention relates to the technical field of lifting equipment, in particular to a one-time forming process for mounting a hanging plate hole of an inclined wheel of a European-style hook assembly and a European-style hook assembly. Background Art

[0002] European hook groups generally adopt advanced design concepts, and their structures are precisely calculated and optimized. For example, the opening part of the hook usually has a device to prevent unhooking, such as a safety tongue. When lifting heavy objects, the safety tongue will automatically lock the hook opening, effectively preventing the heavy objects from accidentally falling off during the lifting process, which to a large extent protects the life safety of the operator and the property safety of the workplace. The existing patent announcement number CN113879973B discloses a method for using an electric hoist for a double-beam European crane. By adjusting the rope, the position of the connecting column can be limited from the left and right directions, which can improve the stability of the connecting column during operation, and thus make it less likely for the hook to shake when lifting objects. However, this traction method requires traction to be set in four directions, and the traction angle also needs to be large, which will undoubtedly cause inconvenience to the lifting. In addition, this hook overload operation is prone to cause danger.

[0003] Based on this, a one-time forming process for mounting the hanging plate hole of the inclined wheel of the European hook group and a European hook group are now provided, which can eliminate the disadvantages of the existing device. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in 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.

[0028] like Figure 1-Figure 8As shown, an embodiment of the present invention provides a European-style hook group, including a lifting slide 102 arranged on a lifting track 100, a walking shaft 103 is rotatably provided at both ends of the lifting slide 102, and a walking wheel 104 matching the lifting track 100 is provided at the end of the walking shaft 103, and a walking drive component for driving the walking shaft 103 to rotate is provided on the lifting slide 102, and the lifting slide 102 can be driven to move smoothly by the walking drive component, and an installation notch is provided in the middle position of the lifting slide 102, and a floating seat 121 is slidably provided at the installation notch position, and a hoisting roller group 101 is provided on the floating seat 121, and a plurality of winding areas for winding a lifting rope 305 are provided on the hoisting roller group 101, and the lifting rope 305 is wound around. 05 The lower end is connected with the inclined axis hook component. Here, multiple groups of lifting ropes 305 are constructed to improve the stability of lifting. Multiple floating side plates 123 are symmetrically arranged on both sides of the floating seat 121. Multiple floating guide rods 124 are slidably arranged on the floating side plates 123. The lower end of the floating guide rod 124 is connected with the lifting slide 102. A floating spring 122 is arranged between the bottom of the floating guide rod 124 and the lifting slide 102. In this way, the floating seat 121 can be supported by the floating side plate 123. An overload limiting component is arranged on the lifting slide 102. When overload occurs, the lifting slide 102 can be made unable to move, thereby ensuring safety. An anti-swing mechanism is arranged at the lower end of the lifting slide 102, and the anti-swing mechanism can improve the stability of transfer. The inclined axis hook component includes two groups of inclined wheel side plates 301, and inclined wheel connecting plates 304 are arranged at both ends between the two groups of inclined wheel side plates 301. The inclined wheel side plates 301 and the inclined wheel connecting plates 304 are connected by multiple connecting pieces 302. A pair of inclined wheel shafts 312 are rotatably arranged between the two inclined wheel side plates 301. The inclined wheel shafts 312 are provided with a lifting inclined wheel 303 for the lifting rope 305 to pass around. The axes of the two hook shafts 313 are in an angled structure, which helps to make the lifting more stable. An anti-detachment hook group for hanging heavy objects is arranged at the lower end of the inclined wheel connecting plate 304. The anti-detachment hook group here can be automatically opened when there is no heavy object, and automatically closed when hanging a heavy object, so as to prevent the heavy object from falling off and improve the safety of lifting. Two sets of shaft holes matching the bevel wheel shaft 312 need to be opened on the bevel wheel side plate 301. Since the bevel wheel shaft 312 is inclined, the inclined holes need to be processed in an inclined manner. The method comprises the following steps: Step 1: firstly fix the two bevel wheel side plates 301 in parallel by a positioning fixture, and then adjust the inclination angle between the bevel wheel side plates 301 and the drill bit; Step 2: Turn on the drilling device to complete the drilling of the two bevel wheel side plates 301 at one time, and then switch the drilling positions of the two bevel wheel side plates 301 to process another set of shaft holes; This drilling method can ensure the parallelism of the shaft holes of the two inclined wheel side plates 301, which not only helps to improve the processing efficiency but also helps to ensure the processing accuracy compared with separate processing. like Figure 7-Figure 8 As shown, the anti-unhooking group includes a hook shaft 313 fixedly arranged at the lower end of the inclined wheel side plate 301, a hook seat 311 is rotatably arranged on the hook shaft 313, a piston cavity 307 is arranged at the lower side of the hook seat 311, a piston block 306 is slidably arranged in the piston cavity 307, the lower end of the piston block 306 is connected to the inner bottom of the piston cavity 307 through a first trigger spring 309, the lower end of the piston block 306 is provided with a contraction groove for accommodating the first trigger spring 309, a hook column 308 is arranged at the lower end of the piston block 306, a hook 310 for hanging materials is arranged at the lower end of the hook column 308, a blocking piece for sealing the upper end of the hook 310 is arranged at the lower end of the hook seat 311, when a heavy object is hung on the hook 310, the hook seat 311 is lifted, the piston block 306 descends, thereby triggering the blocking piece, and at this time the upper end of the hook 310 is automatically sealed without manual operation; like Figure 8 As shown, the blocking member includes an anti-slip truss 316 slidably arranged at the bottom of the hook seat 311, the anti-slip truss 316 is a rectangular frame, and side sliding blocks 317 are symmetrically arranged on both sides of the anti-slip truss 316, and the lower end of the hook seat 311 is provided with a side sliding sleeve 318 that slides and matches with the side sliding block 317. The cooperation between the side sliding block 317 and the side sliding sleeve 318 allows the anti-slip truss 316 to slide smoothly. A reset block 319 is also provided at the lower end of the hook seat 311, and the reset block 319 is connected to the anti-slip truss 316 through a reset spring 320. Under the action of the reset spring 320, the anti-slip truss 316 will slide away from the end of the hook 310, thereby completing the unsealing action, and the anti-slip truss 316 relative to the reset spring 320 The other end is connected to one end of the traction rope 315, and the other end of the traction rope 315 passes around the second guide rod 321 from the inside, passes around the first guide rod 314 from the outside, and is then connected to the piston block 306. The first guide rod 314 and the second guide rod 321 are connected to the mounting plate on the outside of the hook seat 311 at both ends. When a heavy object is hung on the hook 310, the piston block 306 is forced to move downward. When moving downward, the upper end of the traction rope 315 is pulled, and then the anti-drop truss 316 is pulled toward the hook 310 to move, thereby completing the blocking of the upper end of the hook 310 to avoid the problem of falling off. This horizontal blocking method will not cause the problem of being unable to block due to the obstruction of the hanging object, and there is no need for manual opening and unblocking, which helps to improve work efficiency. like Figure 3As shown, the anti-swing mechanism includes a plurality of support rods 401 symmetrically arranged at the lower end of the lifting slide 102, a support sleeve 403 is slidably provided at the lower end of the support rod 401, the support sleeve 403 and the lifting slide 102 are connected by a damping spring 402, and a downward pressing horizontal plate 404 is provided at the lower end of the support sleeve 403 for pressing the upper end of the inclined axis hook component. When transferring, the inclined axis hook component is lifted, and then the downward pressing horizontal plate 404 is pressed against the top of the inclined axis hook component. In this way, even if the inclined axis hook component shakes, the downward pressing horizontal plate 404 will be pushed, and the damping spring 402 at this time can absorb the impact force generated by the swing, making the lifting more stable. The overload limiting component includes a brake base plate 200 arranged on the outside of the lifting slide 102, and the brake base plate 200 is connected and fixed to the first clutch disc 106 by a cross bar. A brake pad group 201 is provided at both ends of each brake base plate 200, and a brake groove matching the running wheel 104 is provided at the lower end of the brake pad group 201. In this way, when the load is overloaded, the floating seat 121 moves downward excessively, and the brake base plate 200 drives the brake pad group 201 to move downward. When the brake pad group 201 moves downward, it is pressed and contacted with the running wheel 104, thereby completing the braking; like Figure 5-Figure 6 As shown, the driving component includes a driving shaft 118, one end of which is rotatably connected to a fixed block on the lifting slide 102, and the other end of the driving shaft 118 is connected to a driving motor 119 for driving the driving shaft 118 to rotate. The driving motor 119 is fixedly installed on the lifting slide 102, and a driving wheel 117 is rotatably provided on the driving shaft 118, and a driven wheel 120 is provided on the walking shaft 103. The driven wheel 120 and the driving wheel 117 are driven by a transmission belt 105. The driving shaft 118 is also provided with a clutch mechanism for driving the driving wheel 117 to rotate. The driving motor 119 drives the driving shaft 118 to rotate, and the driving shaft 118 drives the driving wheel 117 to rotate through the clutch mechanism. The driving wheel 117 drives the driven wheel 120 to rotate through the transmission belt 15, and the driven wheel 120 drives the walking wheel 104 to rotate through the walking shaft 13, thereby obtaining walking power; The clutch mechanism includes a second clutch disc 107 slidably arranged on a drive shaft 118, a rotation limiting unit is arranged between the second clutch disc 107 and the drive shaft 118, a first clutch disc 106 is fixedly arranged at the end of the drive wheel 117, and matching friction tooth surfaces are arranged on the opposing surfaces of the first clutch disc 106 and the second clutch disc 107 to ensure the transmission of power, and a positioning side plate 111 is also fixedly arranged on the drive shaft 118, and the positioning side plate 111 and the second clutch disc 107 are connected by a clutch spring 108, and under the action of the clutch spring 108, the second clutch disc 107 will approach the first clutch disc 106, so as to maintain the second clutch disc 107 and the first clutch disc 106 in a state of tight contact; The rotation limiting unit includes a limiting protrusion 109 arranged on the outside of the driving shaft 118, and a limiting groove matching the limiting protrusion 109 is provided on the second clutch disc 107. The cooperation between the limiting groove and the limiting protrusion 109 enables the second clutch disc 107 to slide along the axis of the driving shaft 118, but cannot rotate in the circumferential direction; like Figure 1-Figure 3 As shown, the overload limit component also includes a cutting mechanism for cutting off the power of the driving component, so that the power can be cut off in time to avoid wear of the clutch mechanism, the cutting mechanism includes a rotating outer ring 110 rotatably arranged on the outside of the second clutch disk 107, a stripping slider 116 is fixedly provided on the outside of the rotating outer ring 110, the stripping slider 116 is slidably arranged on a stripping guide rod 112, the stripping guide rod 112 is horizontally arranged on the lifting slide 102, the two ends of the stripping guide rod 112 are connected and fixed to the vertical plates on the lifting slide 102, the end of the stripping slider 116 is provided with a triangular inclined plate 113, and the triangular inclined plate 113 is provided on the A downward pressure rod 115 is fixedly provided on the outer side of the floating seat 121, and a downward pressure wheel 114 is rotatably provided at the end of the downward pressure rod 115. When the floating seat 121 moves downward due to overload, the downward pressure rod 115 will drive the downward pressure wheel 114 to squeeze the inclined surface of the triangular inclined plate 113, and the triangular inclined plate 113 drives the rotating outer ring 110 to move to one side through the peeling slider 116, thereby separating the second clutch disc 107 and the first clutch disc 106, cutting off the power for walking; a pressure sensor is also provided on the brake pad group 201, and the pressure sensor is connected to an alarm. When the brake pad group 201 is pressed and locked, the alarm will also be triggered, indicating that it is overloaded.

[0029] Working principle: In actual use, the lifting slide 102 is moved along the lifting track 100, and the heavy object is hung with the hook 310. As the hook 310 is loaded, the blocking piece will be triggered. When the heavy object is hung on the hook 310, the piston block 306 is forced to move downward. When moving downward, the upper end of the traction rope 315 is pulled, and then the anti-drop truss 316 is pulled toward the hook 310, thereby completing the blocking of the upper end of the hook 310 to avoid the problem of falling off. If overload occurs, the floating seat 121 is overloaded. When the floating seat 121 moves downward due to overload, the lower pressure rod 115 drives the lower pressure wheel 114 to squeeze the inclined surface of the triangular inclined plate 113, and the triangular inclined plate 113 drives the rotating outer ring 110 to move to one side through the stripping slider 116, so that the second clutch disc 107 and the first clutch disc 106 are separated, and the driving force is cut off; When transferring heavy objects, the inclined axis hook component is raised, and then the upper end position of the inclined wheel side plate 301 is docked with the anti-swing mechanism, and then the downward pressing cross plate 404 is pressed against the top of the inclined axis hook component. In this way, even if the inclined axis hook component shakes, the downward pressing cross plate 404 will be pushed. At this time, the damping spring 402 can absorb the impact force generated by the swing, making the lifting more stable. If the swing is still too large at this time, it will inevitably cause the floating seat 121 to move down. At this time, the alarm will still be triggered, and the brake will be turned on to stop the equipment from moving, avoiding working under large swing conditions, thereby further improving the safety of the equipment.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
