Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, and particularly relates to a self-unloading hoist. Background Art

[0002] During the construction process of engineering projects, it is often necessary to transport building materials such as mixed concrete, bricks, and floors from the ground to a high place. In the actual production process, this transportation process is usually achieved by a hoist. However, although the lifting process can be realized by the hoist, the unloading of the materials still needs to be carried out manually after the materials are lifted to the designated position. It is necessary to manually tilt the hopper to pour the materials out of the hopper. Such manual operation has low work efficiency and is time-consuming and laborious.

[0003] The technical problem to be solved by the utility model is: how to solve the problem that the existing hoist needs manual unloading, resulting in low work efficiency and high labor intensity. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a self-unloading hoist, which has the characteristics of simple structure, convenient use, and automatic unloading.

[0005] The technical solution adopted by the utility model is: a self-unloading hoist, which includes a frame, a lifting mechanism installed on the frame. The frame includes a base, a guide rod installed on the base, a sliding table slidably connected to the guide rod, and a turning table rotatably connected to the sliding table. A part of the turning table is supported by the sliding table, and the other part is suspended above the sliding table. The lifting mechanism includes a traction member and a lifting power member. One end of the traction member is connected to the part of the turning table suspended above the sliding table, and the other end is wound around the guide rod and connected to the lifting power member;

[0006] It further includes a unloading mechanism, which includes a stroke limiting member, an anti-falling member, and a locking member. The stroke limiting member is installed on the guide rod, and the stroke limiting member is sequentially provided with a hook groove and a hook release block from bottom to top. Both the anti-falling member and the locking member are pivotally connected to the sliding table. The anti-falling member is caught in the hook groove to limit the descent of the sliding table. The anti-falling member abuts against the hook release block to make the locking member hook onto the anti-falling member, so as to release the restriction on preventing the sliding table from descending.

[0007] For the self-unloading hoist of the present application, the materials are placed on the turning table, and then the lifting power member drives the sliding table to rise through the traction member. When the anti-falling member is engaged with the hook groove on the stroke limiting member, the traction member is released a certain length. Under the action of gravity, the turning table will turn towards the part suspended above the sliding table, so that the materials on the turning table are unloaded, realizing automatic unloading. After the unloading is completed, the lifting power member drives the sliding table to rise through the traction member again, so that the anti-falling member abuts against the hook release block, making the locking member hook the anti-falling member. Then, the lifting power member releases the traction member to make the sliding table descend to load materials again.

[0008] In some embodiments, a first driving member is disposed between the anti-falling member and the sliding table. The first driving member is configured to drive the anti-falling member to rotate towards the guiding rod. A second driving member is disposed between the locking member and the sliding table. The second driving member is configured to drive the locking member to rotate towards the guiding rod.

[0009] With the above technical solution, by providing the first driving member, the anti-falling member can be always driven to swing towards the guiding rod, ensuring that the anti-falling member can be hooked into the hook groove when passing through the hook groove. Similarly, the second driving member can drive the locking member to always swing towards the guiding rod. When the anti-falling member abuts against the unhooking block, it can ensure that the locking member is hooked to the anti-falling member.

[0010] In some embodiments, the first driving member and the second driving member are elastic members or magnetic members.

[0011] With the above technical solution, the first driving member and the second driving member can be selected as elastic members or magnetic members according to actual needs.

[0012] In some embodiments, the anti-falling member includes a first swing arm and a pin. One end of the first swing arm is pivotally connected to the sliding table, and the other end is connected to the pin. The pin corresponds to the hook groove and the unhooking block. A limiting groove and a first lapping step are provided at one end of the first swing arm away from the pin. A limiting member corresponding to the limiting groove is provided on the sliding table, and a second lapping step corresponding to the first lapping step is provided on the locking member.

[0013] With the above technical solution, when the pin is caught in the hook groove, the sliding table can be prevented from sliding downwards. When the pin abuts against the unhooking block, it will guide the first swing arm to rotate towards the locking member, so that the first lapping step and the second lapping step are hooked, restricting the rotation of the first swing arm in the direction of the hook groove, thereby the restriction that the sliding table cannot descend can be released. The cooperation between the limiting member and the limiting groove can limit the rotation amplitude of the first swing arm, ensuring that the rotation range of the first swing arm is within a better range, and improving the reliability of the structure.

[0014] In some embodiments, the locking member includes a second swing arm and an unlocking rod. One end of the second swing arm is pivotally connected to the sliding table, and the other end is connected to the unlocking rod. The second lapping step is provided on the second swing arm. An unlocking member corresponding to the unlocking rod is provided at the bottom of the guiding rod. The unlocking rod contacts the unlocking member, causing the first lapping step and the second lapping step to separate.

[0015] In some embodiments, one end of the unlocking member is connected to the guiding rod, and the other end extends downward obliquely away from the guiding rod.

[0016] With the above technical solution, after the unlocking rod contacts the unlocking member, the second swing arm will gradually swing along the inclined direction of the unlocking member, so that the second latching step is separated from the first latching step, enabling the first swing arm to swing freely. And setting the unlocking member at the bottom of the guide rod can release the restriction of the locking member on the anti-falling member when the sliding table descends to the bottom of the guide rod to load materials.

[0017] In some embodiments, the stroke limiting member includes two oppositely arranged side plates and a bottom plate connecting the two side plates. There is a guide groove inside the guide rod, and a notch communicating with the outside is formed on one side of the guide rod for the guide groove. The bottom plate is arranged opposite to the notch, and the two side plates are respectively arranged on both sides of the notch. The hook groove and the unhooking block are arranged on the side plates.

[0018] With the above technical solution, the two side plates and the bottom plate form a chamber that wraps the guide rod, which can increase the contact area between the stroke limiting member and the guide rod, making the structure of the stroke limiting member more stable during operation.

[0019] In some embodiments, the stroke limiting member further includes a balance block. One end of the balance block is connected to one of the side plates, and the other end extends towards the edge of the notch of the guide groove.

[0020] With the above technical solution, the balance block can make the force on the stroke limiting member more balanced during operation, improving reliability.

[0021] In some embodiments, the stroke limiting member is detachably connected to the guide rod.

[0022] With the above technical solution, the position of the stroke limiting member on the guide rod can be set according to the actual required lifting height, with better versatility.

[0023] In some embodiments, the unloading mechanism further includes a traction member. One end of the traction member is connected to the guide rod, and the other end is connected to the stroke limiting member.

[0024] With the above technical solution, the traction member can provide a pulling force for the stroke limiting member, making the force on the stroke limiting member more balanced, and can also prevent the stroke limiting member from falling during operation, improving safety.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] Please refer to Figures 1 to 6 , which is a self-unloading hoist 100 of a preferred embodiment of this utility model, including a frame 10, a lifting mechanism 20 and a discharging mechanism 30 installed on the frame 10. The frame 10 includes a base 11, a guide rod 12 installed on the base 11, a sliding table 13 slidably connected to the guide rod 12, and a turning table 14 rotatably connected to the sliding table 13. A part of the turning table 14 is supported by the sliding table 13, and the other part is suspended above the sliding table 13. The lifting mechanism 20 includes a traction member 21 and a lifting power member 22. One end of the traction member 21 is connected to the part of the turning table 14 that is suspended above the sliding table 13, and the other end is wound around a fixed pulley (not shown in the figure) on the top of the guide rod 12 and connected to the lifting power member 22. The discharging mechanism 30 includes a stroke limiting member 31, an anti-falling member 32 and a locking member 33. The stroke limiting member 31 is installed on the guide rod 12, and the stroke limiting member 31 is sequentially provided with a hook groove 311 and a hook release block 312 from bottom to top. Both the anti-falling member 32 and the locking member 33 are pivotally connected to the sliding table 13. The anti-falling member 32 is inserted into the hook groove 311 to limit the descent of the sliding table 13. The anti-falling member 32 abuts against the hook release block 312 to make the locking member 33 hook onto the anti-falling member 32 to release the restriction on preventing the sliding table 13 from descending.

[0036] For the self-unloading hoist 100 of this application, the material is placed on the turning table 14, and then the lifting power member 22 drives the sliding table 13 to rise through the traction member 21. When the anti-falling member 32 is engaged with the hook groove 311 on the stroke limiting member 31, the sliding table 13 cannot descend under the restriction of the hook groove 311. Then the traction member 21 is paid out a certain length, and under the action of gravity, the turning table 14 will turn towards the part that is suspended above the sliding table 13, so that the material on the turning table 14 is unloaded, realizing automatic unloading. After the unloading is completed, the lifting power member 22 drives the sliding table 13 to rise through the traction member 21 again, so that the anti-falling member 32 abuts against the hook release block 312 to make the locking member 33 hook the anti-falling member 32. Then the lifting power member 22 releases the traction member 21 to make the sliding table 13 descend to load materials again.

[0037] In this embodiment, the traction member 21 is a steel wire rope. In other embodiments, the traction member 21 can also be one of an iron chain, a chain, a polymer rope, etc. In this example, the lifting power member 22 is a motor, and the motor is installed on the base 11. In other embodiments, it can also be an internal combustion engine, a manual or animal-powered winch, etc.

[0038] AsFigure 2 and Figure 5 As shown, a guiding groove 121 is provided inside the guiding rod 12. The guiding groove 121 extends along the axial direction of the guiding rod 12, and a notch 122 communicating with the outside is provided on one side of the guiding groove 121. A guiding wheel (not labeled in the figure) that slidably cooperates with the guiding groove 121 is provided on the sliding table 13.

[0039] Preferably, the stroke limiting member 31 is detachably connected to the guiding rod 12. The position of the stroke limiting member 31 on the guiding rod 12 can be set according to the actually required lifting height, and the versatility is better. In this embodiment, the stroke limiting member 31 and the guiding rod 12 are connected by bolts. A through threaded hole is provided on the stroke limiting member 31, and the bolt is connected to the threaded hole. By screwing the bolt, the end of the bolt abuts against the guiding rod 12, thereby fixing the stroke limiting member 31 on the guiding rod 12. The disassembly and assembly are convenient, and the height can be adjusted arbitrarily. Further, in order to better improve the reliability of the installation of the stroke limiting member 31, a reinforcing sleeve 39 is also sleeved at the connection between the stroke limiting member 31 and the bolt. The reinforcing sleeve 39 is sleeved on the outer surfaces of the stroke limiting member 31 and the guiding rod 12, and is provided with a through hole for the bolt to pass through.

[0040] As Figure 1 shown, the unloading mechanism 30 further includes a traction member 38. One end of the traction member 38 is connected to the top of the guiding rod 12, and the other end is connected to the stroke limiting member 31. The traction member 38 can provide a pulling force for the stroke limiting member 31, making the force on the stroke limiting member 31 more balanced, and can also prevent the stroke limiting member 31 from falling during the working process, improving safety. Optionally, the traction member 38 is a rope or a chain.

[0041] As Figure 6 shown, the stroke limiting member 31 includes two oppositely arranged side plates 313 and a bottom plate 314 connecting the two side plates 313. The bottom plate 314 is arranged opposite to the notch 122, and the two side plates 313 are respectively arranged on both sides of the notch 122. The hook groove 311 and the unhooking block 312 are arranged on the side plates 313. The two side plates 313 and the bottom plate 314 form a chamber that wraps the guiding rod 12, which can increase the contact area between the stroke limiting member 31 and the guiding rod 12, making the structure of the stroke limiting member 31 more stable during operation.

[0042] Further, the stroke limiting member 31 further includes a balance block 315. One end of the balance block 315 is connected to one of the side plates 313, and the other end extends towards the edge of the notch 122 of the guiding groove 121. The balance block 315 can make the force on the stroke limiting member 31 more balanced during operation, improving reliability.

[0043] Preferably, a first driving member 34 is provided between the anti-falling member 32 and the sliding table 13. The first driving member 34 is used to drive the anti-falling member 32 to rotate towards the guide rod 12. A second driving member 35 is provided between the locking member 33 and the sliding table 13. The second driving member 35 is used to drive the locking member 33 to rotate towards the guide rod 12. By providing the first driving member 34, the anti-falling member 32 can be driven to swing towards the guide rod 12 all the time, ensuring that the anti-falling member 32 can be hooked into the hook groove 311 when passing through the hook groove 311. Similarly, the second driving member 35 can drive the locking member 33 to swing towards the guide rod 12 all the time. When the anti-falling member 32 abuts against the unhooking block 312, it can ensure that the locking member 33 is hooked to the anti-falling member 32.

[0044] Optionally, the first driving member 34 and the second driving member 35 are elastic members or magnetic members. The first driving member 34 and the second driving member 35 can be selected as elastic members or magnetic members according to actual needs. In this embodiment, the first driving member 34 is a torsion spring and the second driving member 35 is a tension spring. In other embodiments, elastic members that can achieve the same function can also be used.

[0045] As Figure 2 shown in Figure 3 the figure, the anti-falling member 32 includes a first swing arm 321 and a pin 322. One end of the first swing arm 321 is pivotally connected to the sliding table 13, and the other end is connected to the pin 322. The pin 322 corresponds to the hook groove 311 and the unhooking block 312. A limiting groove 323 and a first latching step 324 are provided at the end of the first swing arm 321 away from the pin 322. A limiting member 36 corresponding to the limiting groove 323 is provided on the sliding table 13, and a second latching step 333 corresponding to the first latching step 324 is provided on the locking member 33. When the pin 322 is caught in the hook groove 311, the sliding table 13 can be prevented from sliding downwards. When the pin 322 abuts against the unhooking block 312, it will guide the first swing arm 321 to rotate towards the locking member 33, so that the first latching step 324 and the second latching step 333 are latched, restricting the rotation of the first swing arm 321 in the direction of the hook groove 311, thereby the restriction that the sliding table 13 cannot descend can be released. The cooperation between the limiting member 36 and the limiting groove 323 can limit the rotation amplitude of the first swing arm 321, ensuring that the rotation range of the first swing arm 321 is in a better range, and improving the reliability of the structure. In this embodiment, the number of the first swing arms 321 is two, and the two first swing arms 321 are respectively arranged at both ends of the pin 322.

[0046] Optionally, the pin 322 is rotatably connected or fixedly connected to the first swing arm 321. In order to reduce the resistance suffered by the anti-falling member 32 during the lifting process, the pin 322 is preferably rotatably connected to the first swing arm 321.

[0047] Further, the locking and latching member 33 includes a second swing arm 331 and an unlocking lever 332. One end of the second swing arm 331 is pivotally connected to the sliding table 13, and the other end is connected to the unlocking lever 332. A second latching step 333 is provided on the second swing arm 331. An unlocking member 37 corresponding to the unlocking lever 332 is provided at the bottom of the guide rod 12. The unlocking lever 332 contacts the unlocking member 37, causing the first latching step 324 and the second latching step 333 to separate. In this embodiment, the number of the second swing arms 331 is two, and the two second swing arms 331 are respectively arranged at both ends of the unlocking lever 332. In order to facilitate the connection of the tension spring and enhance the structural strength of the locking and latching member 33, a cross beam is further provided between the two second swing arms 331.

[0048] As Figure 1 shown in Figure 4 FIG. [not shown], one end of the unlocking member 37 is connected to the guide rod 12, and the other end extends downward obliquely away from the guide rod 12. After the unlocking lever 332 contacts the unlocking member 37, the second swing arm 331 will gradually swing along the inclined direction of the unlocking member 37, so that the second latching step 333 and the first latching step 324 are separated, enabling the first swing arm 321 to swing freely. And by arranging the unlocking member 37 at the bottom of the guide rod 12, when the sliding table 13 descends to the bottom of the guide rod 12 to load materials, the restriction of the locking and latching member 33 on the anti-falling member 32 can be released simultaneously.

[0049] Preferably, when the loaded materials are not suitable to be directly placed on the turning table 14, a hopper (not shown in the figure) can be provided on the turning table 14, and the materials are placed in the hopper.

[0050] In use, first, according to the required lifting height, the stroke limiting member 31 is fixed at the corresponding position on the guide rod 12. Then, the material to be transported is placed on the turning table 14. Next, the lifting power member 22 drives the sliding table 13 to rise through the traction member 21. When the anti-falling member 32 rises to the position of the hook groove 311, under the action of the first driving member 34, the latch pin 322 is inserted into the hook groove 311. Due to the limitation of the structure of the hook groove 311, at this time, the sliding table 13 can only rise and cannot fall. The lifting power member 22 drives the traction member 21 to retract a certain length. Under the action of gravity, the turning table 14 turns to dump the material of the device, completing automatic discharging. Then, the lifting power member 22 drives the traction member 21 to wind up, driving the turning table 14 to reset and rise. When the latch pin 322 contacts the unhooking block 312, it causes the anti-falling member 32 to rotate away from the guide rod 12, so that the first lapping step 324 is hooked with the second lapping step 333, restricting the anti-falling member 32 from rotating towards the guide rod 12. Then, the lifting power member 22 drives the traction member 21 to unwind, and the sliding table 13 descends. Due to the limitation of the locking and latching member 33, the latch pin 322 will not be inserted into the hook groove 311 again during the descending process. Therefore, the sliding table 13 can descend to the lowest position. When the unlocking rod 332 of the locking and latching member 33 contacts the unlocking member 37, the locking and latching member 33 gradually rotates away from the guide rod 12, causing the first lapping step 324 to separate from the second lapping step 333, releasing the limitation on the rotation of the anti-falling member 32. Repeating the above actions can continuously lift and transport the material.

[0051] Finally, it should be noted that the above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
