Description

Technical Field

[0001] This invention relates to the field of hoist technology, specifically to a stable and efficient hoist for intelligent warehousing. Background Technology

[0002] Smart warehousing utilizes automation technology to store goods and materials. During the goods transportation process, forklifts are used. Forklifts are a type of high-efficiency vertical conveying equipment that achieves continuous cyclic lifting of materials through a forklift structure and chain drive. They mainly adopt a modular design, have a compact structure and few moving parts, and are equipped with a closed drive device to ensure operational stability and safety. Furthermore, the forks are made of high-strength materials to support precise material positioning, and the columns are reinforced to bear heavy loads and adapt to high-intensity working environments.

[0003] Existing forklift elevators typically use forklift seats to lift or lower goods. During the lifting process, the goods will sway due to vibrations generated by the elevator itself. Therefore, some forklift seats are equipped with limit plates to limit the goods. Since the position of the limit plates is not adjustable after installation, if the distance between the limit plates differs too much from the size of the goods, there will still be gaps between the goods and the limit plates during the transport process, and the goods will still sway and tilt during the lifting process. If the distance between the limit plates is close to the size of the goods, the goods will not be able to quickly insert between the two sets of limit plates, thus affecting the lifting efficiency of the goods.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

If the distance between the limit plates differs too much from the size of the goods, the goods will still sway and tilt during the lifting process. If the distance between the limit plates is close to the size of the goods, the goods cannot be quickly inserted between the two sets of limit plates, affecting the lifting efficiency of the goods. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stable and efficient hoist for intelligent warehousing, comprising a main body of a telescopic boom hoist, wherein the lifting slider of the main body of the telescopic boom hoist is connected to a mounting frame via a rotating shaft, a rotating rod is rotatably connected to the upper inner side of the mounting frame via a bearing seat, the rotating rod is connected to an inner ring on the outer side of the mounting frame, an outer toothed ring is provided on the outer side of the inner ring, a semi-circular protrusion is connected to the inner side of the outer toothed ring, an inclined block is slidably connected to the inner ring, and the inclined block and the semi-circular protrusion are in contact, the rotating rod is connected to a first threaded rod on the inner side of the mounting frame via a transmission belt, the first threaded rod is threadedly connected to a sliding frame, a limit rod is slidably connected to the inner side of the sliding frame, a support frame is connected to the outer side of the mounting frame, guide wheels are rotatably connected to both sides of the limit rod, a guide groove is provided on the inner side wall of the support frame, and the guide wheels are located in the guide groove on the inner side of the support frame;

[0010] Preferably, the external toothed ring is rotatably connected to the outer wall of the mounting frame via a hollow bearing, and the rotating rod is located inside the hollow bearing.

[0011] Preferably, there are two sets of lead screw slides, and the two sets of lead screw slides are located on the upper left side and the lower right side of the main body of the boom lift, respectively.

[0012] Preferably, the inner side of the adjusting component also has a spring connected to one side of the transmission disk, and the other end of the spring is connected to the inner wall of the inner ring groove.

This allows the staff to quickly adjust the limit rod and the limit frame according to the size of the goods, so as to achieve stable and limited conveying of goods of different sizes.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-10 This invention provides a technical solution: a stable and efficient hoist for intelligent warehousing, comprising a boom hoist body 1, a hoist body 1 with a lifting slider connected to a mounting frame 2 via a rotating shaft, a rotating rod 3 rotatably connected to the upper inner side of the mounting frame 2 via a bearing seat, an inner ring 4 connected to the rotating rod 3 on the outer side of the mounting frame 2, an outer toothed ring 5 provided on the outer side of the inner ring 4, a semi-circular protrusion 6 connected to the inner side of the outer toothed ring 5, a slidably connected inclined block 13 to the inner ring 4, and the inclined block 13 fitting against the semi-circular protrusion 6, a first threaded rod 8 connected to the inner end of the rotating rod 3 on the mounting frame 2 via a transmission belt, a sliding frame 9 threadedly connected to the first threaded rod 8, and a sliding frame 9 on the inner side of the sliding frame 9. A sliding connection is provided with a limiting rod 10. A support frame 7 is connected to the outside of the mounting frame 2. Guide wheels 14 are rotatably connected to both sides of the limiting rod 10. A guide groove is provided on the inner side wall of the support frame 7, and the guide wheels 14 are located in the guide groove on the inner side of the support frame 7. During the conveying of goods, the main body 1 of the insert-arm type elevator will automatically drive the rotating rod 3 to rotate. The rotation of the rotating rod 3 will drive the limiting rod 10 to move. The unfolded limiting rod 10 will calibrate and limit the goods, reducing the possibility of the goods deviating or tipping during the conveying process. When the goods fall to a suitable height, the limiting rod 10 will automatically separate from the goods and store them, thereby ensuring the lifting and conveying efficiency of the goods.

[0033] Adjustment component 11 is disposed on the outer wall of the main body 1 of the boom hoist; limiting component 12 is disposed inside the mounting frame 2.

[0034] In one embodiment of the present invention, the adjusting component 11 has a transmission disc 112 connected to one side of the inclined block 13. A screw slide 113 is installed on the outer wall of the main body 1 of the insert-arm type elevator. The slider of the screw slide 113 is connected to the inclined panel 111. A transmission rack is provided on the outer side of the frame of the screw slide 113, and the transmission rack is meshed with the outer toothed ring 5. By starting the screw slide 113, the inclined panel 111 can be driven to move vertically. After the position of the inclined panel 111 is adjusted, the number of rotations of the rotating rod 3 will change, thereby adjusting the moving distance of the limiting rod 10. This makes it convenient for the staff to quickly adjust the limiting rod 10 according to the size of the goods, so as to realize the limited and stable conveying of goods of different sizes.

[0035] In one embodiment of the present invention, the limiting component 12 has a first bevel gear 121 connected to one end of the rotating rod 3, a second threaded rod 122 rotatably connected to the upper inner side of the mounting frame 2, and a second bevel gear 123 connected to the bottom end of the second threaded rod 122. The second bevel gear 123 meshes with the first bevel gear 121. The second threaded rod 122 is threadedly connected to a limiting frame 124, and the limiting frame 124 is slidably connected to the mounting frame 2. During the rotation of the rotating rod 3, the second threaded rod 122 will also rotate. The rotation of the second threaded rod 122 will drive the limiting frame 124 to move vertically. The vertical movement of the limiting frame 124 can limit the upper part of the goods, further improving the stability of the goods during the transportation process.

[0036] In one embodiment of the present invention, the external gear ring 5 is rotatably connected to the outer wall of the mounting frame 2 via a hollow bearing, and the rotating rod 3 is located inside the hollow bearing. By setting the hollow bearing to limit the external gear ring 5, the stability of the external gear ring 5 during rotation is improved.

[0037] In one embodiment of the present invention, two sets of lead screw slides 113 are provided, and the two sets of lead screw slides 113 are respectively located on the upper left side and the lower right side of the main body 1 of the boom lift. The inner side of the adjustment component 11 also has a spring connected to one side of the transmission disk 112, and the other end of the spring is connected to the inner wall of the groove of the inner ring 4. The transmission disk 112 is slidably connected to a guide rod, and the guide rod is connected to the groove of the inner ring 4. The guide rod passes through the hole formed in the center of the spring. The spring can make the transmission disk 112 quickly return to the initial position, thereby ensuring that the outer toothed ring 5 can subsequently drive the rotating rod 3 to rotate through the semi-circular protrusion 6 and the inclined block 13. The guide rod limits the spring to reduce the occurrence of spring deformation and misalignment. The inclined plate 111 is rotatably connected to a sliding roller, and there is a gap between the sliding roller and the rack of the lead screw slide 113. By providing multiple sets of sliding rollers, the friction damage generated when the transmission disk 112 slides against the inclined plate 111 is reduced, thereby improving the service life of the transmission disk 112.

[0038] In one embodiment of the present invention, a rotating block is fixedly connected to the bottom end of the second threaded rod 122, and the rotating block is connected to the inner wall of the mounting frame 2. By setting the rotating block, one end of the second threaded rod 122 is limited, thereby improving the stability of the second threaded rod 122 during rotation. The limiting frame 124 is provided with two sets of pressure rods on the outside of the rotating rod 3, and both sets of pressure rods are slidably connected to the rotating rod 3. By setting the two sets of pressure rods, the goods can be limited up and down, reducing the shaking of the goods during the lifting and conveying process.

[0039] Working Principle: First, when goods need to be transported, the main body 1 of the boom lift is started. The internal chain slider of the boom lift 1 drives the mounting frame 2 to rise. The movement of the mounting frame 2 drives the support frame 7 to move. The movement of the support frame 7 lifts the goods and separates them from the conveyor belt. During the rising process of the mounting frame 2, it also drives the external toothed ring 5 to move. The external toothed ring 5 will mesh with the rack of the screw slide 113 and rotate. The rotation of the external toothed ring 5 drives the semi-circular protrusion 6 to rotate. The rotation of the semi-circular protrusion 6 drives the inclined block 13 to rotate. The rotation of the inclined block 13 drives the inner ring 4 to rotate. The rotation of the inner ring 4 drives the rotating rod 3 to rotate. Under the influence of the synchronous belt, the rotation of the rotating rod 3 drives the first threaded rod 8 to rotate. Since the first threaded rod 8 is threadedly connected to the sliding frame 9, and the sliding frame 9 is slidably connected to the support frame 7, the rotation of the first threaded rod 8 can drive the sliding frame 9 to move horizontally towards the mounting frame 2 under the influence of the thread. During the movement of the sliding frame 9, it will drive the limit rod 10 to move. Since the guide wheels 14 on both sides of the limiting rod 10 are embedded in the guide groove of the support frame 7, the limiting rod 10 will also move upward during the horizontal movement to complete the automatic unfolding of the limiting rod 10. The horizontal movement of the limiting rod 10 will gradually fit against the goods, calibrate the position of the goods and limit their movement.

[0040] Secondly, during the rotation of the rotating rod 3, the first bevel gear 121 will also rotate. Since the first bevel gear 121 is meshed with the second bevel gear 123, the rotation of the first bevel gear 121 will drive the second bevel gear 123 to rotate. The rotation of the second bevel gear 123 will drive the second threaded rod 122 to rotate. Since the limiting frame 124 is threadedly connected to the second threaded rod 122 and the limiting frame 124 is slidably connected to the mounting frame 2, the rotation of the second threaded rod 122 will drive the limiting frame 124 to move downward. The downward movement of the limiting frame 124 limits the upper part of the goods. By cooperating with the limiting rod 10, the limiting frame 124 limits the goods and reduces the swaying of the goods during the upward movement.

[0041] Then, when the external gear ring 5 rises to the position of the first set of inclined panels 111, the inclined surface of the transmission disc 112 will fit against the inclined panel 111 and move. The transverse movement of the transmission disc 112 pushes the inclined block 13 to move. The movement of the inclined block 13 separates from the semi-circular protrusion 6, so that the rotation of the external gear ring 5 cannot drive the rotating rod 3 to rotate, thereby limiting the movement distance of the limiting rod 10 and the limiting frame 124, avoiding the situation where the limiting rod 10 and the limiting frame 124 squeeze and damage the goods. During the vertical movement of the transmission disc 112, it will separate from the first set of inclined panels 111, and the inner ring 4 will be concave. The spring in the groove will push the transmission disk 112 back to the initial position. Since both the inclined block 13 and the semi-circular protrusion 6 are inclined, the inclined block 13 will re-enter the gap of the semi-circular protrusion 6 under the action of the spring. When the rotating rod 3 moves to the position of the second set of lead screw slide 113, the external toothed ring 5 will mesh with the gear on the outside of the second set of lead screw slide 113 and rotate in the opposite direction. The reverse rotation of the external toothed ring 5 causes the limiting rod 10 and the limiting frame 124 to separate from the goods, thereby releasing the limitation of the goods. The goods can be transported through the conveying structure above the main body 1 of the insert-arm type elevator.

[0042] Finally, when it is necessary to adjust the moving distance of the limit rod 10, the lead screw slide 113 is activated. The operation of the lead screw slide 113 drives the inclined panel 111 to move vertically, thereby adjusting the position of the lead screw slide 113 and adjusting the moving distance between the limit rod 10 and the limit frame 124, so as to limit the goods of different sizes.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
