Description

Technical Field

[0001] The utility model relates to the field of hoisting equipment, in particular to a hoisting device for transporting molds. Background Art

[0002] When transporting heavy molds such as steel and iron from bottom to top, lifting equipment with stronger carrying capacity is often used to replace manual handling, which reduces the labor intensity of workers and improves handling efficiency.

[0003] Commonly used handling hoists usually have a hook hung at the end of the hanging wall. The mold is manually placed in a lifting bag or tied with a binding belt and then hung on the hook. The receiving platform then arranges corresponding personnel to take and place the mold from the hook.

[0004] However, the above method only plays a unilateral role in reducing labor intensity. Since loading and unloading at the beginning and end takes a lot of time, the actual lifting efficiency has not been significantly improved. Utility Model Content

[0005] In order to shorten the loading and unloading time and improve the lifting efficiency, the present application provides a lifting device for mold transportation.

[0006] The present application provides a mold handling hanger, which adopts the following technical solution:

[0007] A mold handling hanger, used for handling cast iron molds, comprising:

[0008] Column, fixedly installed on the ground;

[0009] The suspension arm comprises a crossbeam, a suspension rod and a clamp, wherein the crossbeam is slidably connected to the top of the column, the suspension rod is hinged to one end of the crossbeam, the clamp is installed at one end of the suspension rod away from the crossbeam, and a positioning piece is provided on the clamp, and the positioning piece is used to align the clamp with the mold;

[0010] The driving assembly is used to drive the lifting arm to lift the mold.

[0011] By adopting the above technical solution, a clamp with a positioning piece is provided, so that the positioning piece can automatically align with the mold to be transported during loading, thereby facilitating the clamp to clamp, saving loading time and improving lifting efficiency.

[0012] Furthermore, a hook is provided at the end of the suspension rod, a hanging ring is provided at the top of the clamp, and the clamp is hung on the hook.

[0013] By adopting the above technical solution, the original hook of the hanger is retained, and the clamp is detachably connected to the hook by hanging. The clamp is used for directional transportation of the cast iron mold. In addition, after removing the clamp, the hanger can be used for other purposes, thereby expanding the application scope of the hanger and improving the utilization efficiency.

[0014] Furthermore, the positioning member is an electromagnet.

[0015] By adopting the above technical solution, the ferromagnetic characteristics of the cast iron mold are utilized and the positioning part is set as an electromagnet. The positioning part can not only accurately position the mold, but also generate magnetic force to adsorb the mold, thereby reducing the load of the clamp and playing a role in auxiliary load-bearing.

[0016] Furthermore, the clamp includes a connecting piece, the hanging ring is fixedly connected to the connecting piece, the electromagnet is installed on a side of the connecting piece facing away from the hanging ring, and two suction cups are rotatably connected to the connecting piece. The two suction cups are arranged opposite to each other and are located on both sides of the electromagnet, and the suction cups are externally connected to a vacuum pump.

[0017] By adopting the above technical solution, two suction cups are arranged opposite to each other as two clamping claws of the clamp, and the suction cups are connected to the vacuum pump. The suction cups adsorb the mold from both sides, which can make the bottom of the clamp open, so as to facilitate automatic clamping of the mold during loading. In addition, the electromagnet adsorbs the mold from above, which is conducive to dispersing the force and improving the durability of the equipment.

[0018] Furthermore, an elastic member is provided between the suction cup and the connecting member, and when the vacuum pump is not started, the elastic member is used to keep the two suction cups away from each other.

[0019] By adopting the above technical solution, when the vacuum pump is not started, the suction cups hinged on both sides of the connecting piece open outward at the ends under the action of the elastic piece, which can prevent the loading from getting stuck and make the mold enter between the two suction cups more smoothly. When loading, it is only necessary to manually overcome the elastic force to make the suction cup abut against the mold to start the vacuum pump, which is convenient to operate.

[0020] Furthermore, a counterweight is provided at one end of the cross beam away from the suspension rod.

[0021] By adopting the above technical solution, the counterweight can balance the force on the beam, extend its service life, and reduce the load on the drive component.

[0022] Furthermore, the counterweight is formed by splicing a plurality of identical unit modules, a protrusion is provided on one side of the unit module, a slot is provided at a corresponding position on a side of the unit module away from the protrusion, and the protrusion is plugged into and matched with the slot of an adjacent unit module.

[0023] By adopting the above technical solution, the counterweight formed by splicing a plurality of identical unit modules end to end can more easily adjust its own weight according to the weight of the mold, thereby expanding the application scope of the sling.

[0024] Furthermore, the counterweight is hung on the crossbeam through a rope, and a rope groove is provided on the unit module.

[0025] By adopting the above technical solution, compared with directly fixing the counterweight to the crossbeam, the counterweight is suspended by a rope, which lowers the center of gravity of the counterweight and can reduce the loss caused by the accidental fall of the counterweight. Moreover, the lowered center of gravity makes it easier for workers to increase or decrease the number of unit modules. The rope embedded in the rope groove can increase the connection strength between the rope and the counterweight.

[0026] Furthermore, a slide groove for lifting and lowering the beam is opened on the column, a screw rod is rotatably connected on the top of the column, the beam is sleeved on the screw rod and threadedly connected to the screw rod, and a driving assembly is installed on the top of the column, including a reduction motor, a hydraulic cylinder and a control switch electrically connected to the two, the reduction motor is used to drive the screw rod to rotate, and the output end of the hydraulic cylinder is hinged to the suspension rod.

[0027] By adopting the above technical solution, a screw is set as a lead screw for the crossbeam to slide, and a reduction motor and a hydraulic cylinder are set to respectively control the lifting and lowering of the crossbeam and the opening and closing of the suspension rod, so that the operator can control the suspension device more flexibly.

[0028] Furthermore, the control switch is a grip handle, and the reduction motor and the hydraulic cylinder are each electrically connected to one of the grip handles.

[0029] By adopting the above technical solution, a grip handle is set as a pressure control switch to control the operation of the reduction motor and the hydraulic cylinder. The operation is simple and easy. Compared with the traditional remote control or button switch, the operator can observe the lifting situation while operating. The running speed of the equipment can be intuitively reflected through the pressure change feedback from the grip handle through touch, which improves the coordination of the senses. The left and right hands control the reduction motor and the hydraulic cylinder respectively, which overcomes the timing of the operating steps between the two, and can adjust the vertical height and horizontal distance of the clamp at the same time, thereby shortening the lifting time and improving efficiency.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. By setting a fixture with a positioning piece, the positioning piece can automatically align with the mold to be transported during loading, which is convenient for the fixture to clamp, saves loading time, and improves lifting efficiency;

[0032] 2. Taking advantage of the ferromagnetic characteristics of the cast iron mold, the positioning piece is set as an electromagnet. The positioning piece can not only accurately position the mold, but also generate magnetic force to adsorb the mold, thereby reducing the load of the fixture and playing a role in auxiliary load-bearing;

[0033] 3. By setting two suction cups facing each other as the clamping claws of the fixture and connecting the suction cups with the vacuum pump, the suction cups absorb the mold from both sides, which can make the bottom of the fixture open, and facilitate automatic clamping of the mold during loading; the suction cups cooperate with the electromagnet to absorb and fix the mold from three directions, which is conducive to dispersing the force and improving the durability of the equipment.

[0040] The following is combined with Figure 1-4 The technical solution of this application is described clearly and completely.

[0041] The embodiment of the present application discloses a hanger for transporting a mold.

[0042] Reference Figure 1A lifting device for transporting a mold 10 includes a column 1, a lifting arm 2 and a driving assembly 3. The column 1 is fixedly installed on the ground, the lifting arm 2 is movably installed on the top of the column 1, and the driving assembly 3 drives the lifting arm 2 to move to transport the cast iron mold 10. The lifting arm 2 also includes a crossbeam 21, a suspension rod 22 and a clamp 23. The crossbeam 21 is connected to the column 1 as a main force-bearing component, the suspension rod 22 is vertically hung at one end of the crossbeam 21, and the clamp 23 is installed at the tail end of the suspension rod 22. A positioning piece is provided on the clamp 23, which can automatically align the clamp 23 with the mold 10, realize rapid loading, and improve the lifting efficiency.

[0043] Reference Figure 1 , Figure 2 A box-shaped mounting portion is provided at the top of the column 1 for mounting the sling and accommodating the drive assembly 3. The opposite side of the mounting portion is horizontally penetrated for the insertion of the crossbeam 21, and a slide groove 11 is provided on the mounting portion for the lifting and lowering of the crossbeam 21. A screw rod 12 is rotatably connected in the mounting portion, and the crossbeam 21 is sleeved on the screw rod 12 and threadedly connected with the screw rod 12. The suspension rod 22 is hinged to one end of the crossbeam 21. In order to expand the use scenario of the suspension rod, a hook 221 is still provided at the end of the suspension rod 22, and a hanging ring 232 is provided at the top of the clamp 23 to hang the clamp 23 on the hook 221. The original hook 221 of the suspension rod 22 is retained, and the clamp 23 is detachably connected to the hook 221 by hanging. The clamp 23 is designed for transporting this type of square cast iron mold 10. In addition, after removing the clamp 23, the suspension rod can be used for other purposes, thereby expanding the scope of application of the suspension rod.

[0044] Reference Figure 3 Considering the ferromagnetic nature of the cast iron mold 10, the electromagnet 231 is selected as the positioning member. The positioning member can not only accurately position the mold 10, but also generate magnetic force to attract the mold 10, thereby reducing the load of the clamp 23 and playing a role in auxiliary load bearing. The clamp 23 also includes a connecting member 233. In this embodiment, (combined with Figure 1 ) The connecting member 233 is a cylindrical pier. In other embodiments, the connecting member 233 may also be of other shapes. The hanging ring 232 is vertically inserted into the center of the end face of the connecting member 233 through a shaft rod. The hanging ring 232 and the connecting member 233 can be fixed by welding or threaded connection. The electromagnet 231 is disc-shaped and is installed on the end face of the connecting member 233 away from the hanging ring 232. Two suction cups 234 are symmetrically arranged on both sides of the connecting member 233. The suction cup 234 is hinged to the outer peripheral wall of the connecting member 233 through a steel pipe, and the suction cup 234 is connected to the vacuum pump.

[0045] The two suction cups 234 arranged opposite to each other serve as the clamping claws of the clamp 23, and use suction to adsorb to the surface of the mold 10 from both sides, so that the bottom of the clamp 23 is open, which is convenient for automatically clamping the mold 10 when loading; in addition, the electromagnet 231 adsorbs the mold 10 from above, so that the three directions in the same plane of the mold 10 are constrained, which is conducive to dispersing the force and improving the durability of the equipment. In other embodiments, four suction cups 234 can be optionally provided, and the suction cups 234 are distributed in a cross shape around the connecting piece 233 in a top view, so as to further enhance the restraining effect of the suction cups 234 on the mold 10.

[0046] Reference Figure 4 In order to prevent the suction cup 234 from interfering with the mold 10 during feeding, an elastic member 235 may be provided between the suction cup 234 and the connector 233. In this embodiment, the elastic member 235 is preferably a spring. When the vacuum pump is not started, the spring is in a free state. At this time, the steel tube end of the suction cup 234 opens outward, so that the two suction cups 234 remain away from each other, thereby preventing the feeding from getting stuck and allowing the mold 10 to enter between the two suction cups 234 more smoothly. When feeding, it is only necessary to manually overcome the elastic force to bring the suction cup 234 into contact with the mold 10, and then the vacuum pump can be started. The structure is simple and the operation is convenient.

[0047] Reference Figure 1 , Figure 2 The drive assembly 3 includes a reduction motor 31, a hydraulic cylinder 32, and a control switch electrically connected to the two. The reduction motor 31 is fixedly installed at the top center of the mounting portion of the column 1 to drive the screw 12 to rotate. The mounting portion of the column 1 limits the rotation of the crossbeam 21, so that the crossbeam 21 can only slide vertically along the screw 12, thereby adjusting the height of the clamp 23. The hydraulic cylinder 32 is located below the crossbeam 21 and is fixedly connected to the mounting portion of the column 1. The output end of the hydraulic cylinder 32 is hinged to the top of the suspension rod 22. The hydraulic cylinder 32 telescopes and drives the suspension rod 22 to rotate, thereby adjusting the horizontal position of the clamp 23. The control switch can be selected to be set as a grip handle 33, and the reduction motor 31 and the hydraulic cylinder 32 are each electrically connected to a grip handle 33. The grip handle 33 is suspended near the bottom of the column 1 by wires for easy grasping by the operator.

[0048] Compared with traditional remote controls or button switches, the operator can operate while observing the hoisting situation, and the operating speed of the equipment can be intuitively reflected by the pressure change fed back by the grip handle 33, which improves the coordination of the senses. The operator's left and right hands control the reduction motor 31 or the hydraulic cylinder 32 respectively, overcoming the timing of the operating steps of the two, and can adjust the vertical height and horizontal distance of the clamp 23 at the same time, which helps to shorten the hoisting time and improve efficiency.

[0049] Reference Figure 1, a counterweight 4 is also provided at one end of the crossbeam 21 away from the suspension rod 22. The counterweight 4 can balance the force of the crossbeam 21, extend its service life, and reduce the load of the drive assembly 3. The counterweight 4 is composed of a plurality of identical unit modules 41, which is convenient for adjusting its own weight according to the weight of the mold 10, thereby expanding the scope of application of the sling. A protrusion 411 is provided on one side of the unit module 41, and a slot 412 is provided at a corresponding position on the side of the unit module 41 away from the protrusion 411. The protrusion 411 is plugged and matched with the slot 412 of the adjacent unit module 41 to connect the plurality of unit modules 41 into a whole. A rope 211 is fixedly installed at one end of the crossbeam 21 away from the suspension rod 22. Compared with directly fixing the counterweight 4 to the crossbeam 21, the counterweight 4 is suspended by the rope 211, which lowers the center of gravity of the counterweight 4, and can minimize the accidental fall of the counterweight block; and the lowered center of gravity makes it easier for workers to increase or decrease the number of unit modules 41.

[0050] In this embodiment, the unit module 41 is a circular pier, and the protrusion 411 and the slot 412 are respectively located in the center of the two end faces of the circular pier. The counterweight 4 is hung on the crossbeam 21 by three ropes 211, and the tops of the three ropes 211 intersect. The more the number of unit modules 41, the tighter the ropes 211 are tied, so as to avoid shaking and falling due to too many unit modules 41. The outer peripheral wall of the unit module 41 is provided with rope grooves 413 corresponding to the ropes 211. The rope grooves 413 pass through the two end faces of the unit module 41. The ropes 211 are embedded in the rope grooves 413 to improve the connection strength between the ropes 211 and the counterweight, thereby improving safety.

[0051] The above are all preferred embodiments of the present application. Obviously, the embodiments described above are only preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made by ordinary technicians in this field based on the structure, shape, and principle of the present application without making any creative work should be covered within the protection scope of the present application.
