Abstract
Description
Technical Field
[0001] This utility model relates to the field of logistics lifting device technology, specifically a safety protection component for a logistics lifting device. Background Technology
[0002] Continuous elevators are used in numerous industries, including electronics, home appliances, auto parts, motorcycles, food, pharmaceuticals, tobacco, postal services, airports, and logistics distribution centers. They have also become essential lifting equipment in the entire production process for companies in the beverage, beer, cigarette, postal, newspaper, printing, food, pharmaceutical, logistics, and electronics industries.
[0003] For example, the authorization announcement number "CN216917491U" describes a forklift circulation lift that replaces manual lubrication of the chain. It provides quantitative and even lubrication of the chain while the lift is running, preventing incomplete lubrication that can lead to rust and wear, thus extending the chain's lifespan. Existing forklift circulation lifts are used in logistics lifting devices, using chain transmission to lift goods to higher levels. However, current forklift circulation lifts use forks to lift and transport box-shaped goods. The forks consist of only multiple horizontal round rods and lack additional protective structures. Therefore, the height of the goods changes continuously during the lifting process, and the higher the height, the greater the risk of the goods falling. Forklift circulation lifts lacking safety protection structures are prone to damage from impacts, significantly increasing operating costs.
[0004] Furthermore, existing forklift hoists require the forks to move cyclically to achieve uninterrupted cargo lifting. During this cyclical movement, the cargo needs to be transported from a low point to a high point, and then descend to the other side of the conveyor belt. As a result, the cargo will suddenly fall after reaching the highest point, and due to inertia, it will maintain an upward trajectory for a period of time. Therefore, without limiting guidance, the cargo is prone to bumping and tilting, reducing the accuracy of material lifting. Utility Model Content
[0005] The purpose of this invention is to solve the problems of increased operating costs and poor material lifting accuracy of existing forklift hoists, and to propose a safety protection component for a logistics lifting device.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] Design a safety protection component for a logistics lifting device, including a material hoist body, bases, and a conveyor for transporting goods. Two bases are fixedly installed at the lower end of the material hoist body. A material input conveyor belt is provided on one side below the material hoist body, and a material unloading conveyor belt is provided on the other side above the material hoist body. A sprocket drive structure is fixedly connected to the front end of the material hoist body. A goods high-point limiting transmission structure is provided above the material hoist body, and a safety protection component is provided below the material input conveyor belt.
[0008] Preferably, the safety protection component includes uprights and connecting blocks. Multiple uprights are fixedly installed at the lower ends of the material input conveyor belt and the material unloading conveyor belt. Support feet are fixedly connected to the bottom ends of multiple uprights. Mounting holes are fixedly opened on the outer walls of multiple uprights. Threaded heads are threaded to the inner sides of multiple mounting holes. Connecting blocks are fixedly installed on the outer sides of multiple threaded heads. Extension columns are fixedly installed on the outer walls of the connecting blocks. Hooks are fixedly installed on the side walls of the extension columns. Anti-fall nets are movably connected to the outer sides of multiple hooks.
[0009] Preferably, the sprocket drive structure includes a lifting track and movable seats. The lifting track is fixedly installed at the front end of the material hoist body. Multiple movable seats are slidably installed on the inner side of the lifting track. Crossbeams are fixedly connected to the outer walls of the multiple movable seats. Forks are fixedly installed on the outer side of the crossbeams.
[0010] Preferably, the tops of the plurality of forks are movably connected to the lower end of the conveyed goods, the conveyed goods are movably connected to the end of the material input conveyor belt, and the conveyed goods are movably connected to the upper part of the other end of the material unloading conveyor belt.
[0011] Preferably, the cargo high-point limiting transmission structure includes a protrusion and a limiting groove. The protrusion is fixedly installed at the top of the material hoist body. A horizontal plate is fixedly installed above the protrusion. Side plates are fixedly installed on both sides of the lower end of the horizontal plate. The limiting groove is fixedly connected to the inner side of the side plate. Multiple pulleys are rotatably connected to the outer wall of the limiting groove through a pin.
[0012] Preferably, the plurality of forks are slidably disposed with respect to the rollers at the ends of the material input conveyor belt, and the plurality of forks are slidably disposed with respect to the rollers at the other ends of the material unloading conveyor belt.
[0013] The safety protection component for a logistics lifting device proposed in this utility model has the following advantages: the anti-fall net is woven from highly elastic and tough nylon paracord. The anti-fall net can be hung on hooks on both sides, so that the anti-fall net can be extended and set on the outside of the upright. Similarly, the connecting block can be fixed to the base by screwing in the screw head. Also, an extended anti-fall net extends out from the lower end of the front of the material lifting machine body. In this way, if the goods fall during the lifting and conveying process, they can be caught by the extended anti-fall net and will not fall directly to the ground, thus protecting the integrity of the goods and reducing the use cost of the logistics lifting device.
[0014] The protrusion is vertically welded to the top of the material hoist body, supporting the horizontal plate. Two side plates are welded to both sides of the horizontal plate, forming an inverted top cover structure that sits atop the material hoist body. The limiting groove is made of aluminum alloy with an inner curved canopy. Multiple pulleys rotate on the outer wall of the limiting groove. When the material hoist body drives the conveying goods in a circular circulation pattern, the conveying goods will be blocked by the limiting groove at the highest point, restricting their movement trajectory. This alleviates the problem of the conveying goods being thrown out due to inertia and improves the accuracy of the lifting. Attached Figure Description

A cargo high-point limiting transmission structure 6 is provided above the material lifting machine body 1. A safety protection component 8 is provided below the material input conveyor belt 3.
[0025] The safety protection component 8 includes uprights 81 and connecting blocks 84. Multiple uprights 81 are fixedly installed at the lower ends of the material input conveyor belt 3 and the material discharge conveyor belt 4. Support feet 82 are fixedly connected to the bottom ends of the uprights 81. The support feet 82, in conjunction with the vertical uprights 81, support the material input conveyor belt 3 and the material discharge conveyor belt 4 on both sides of the material elevator body 1. The material input conveyor belt 3 is lower for conveying the material 5 into the conveyor, while the material discharge conveyor belt 4 is higher for conveying the material 5 out of the conveyor. Mounting holes 83 are fixedly opened on the outer walls of the multiple uprights 81, arranged side-by-side. Threaded grooves are opened inside the mounting holes 83, allowing the connecting blocks 84 to be screwed into the mounting holes 83 using threaded heads 85. The height of the connecting blocks 84 outside the uprights 81 can be determined based on the height of the selected mounting holes 83. Threaded heads 85 are threadedly connected to the inner sides of the multiple mounting holes 83. A connecting block 84 is fixedly installed on the outer side of the threaded head 85. An extension column 86 is fixedly installed on the outer wall of the connecting block 84. The extension column 86 is made of stainless steel metal tube and is welded to the outer side of the connecting block 84. The side wall of the extension column 86 is provided with multiple rows of curved metal hooks 87. The hooks 87 are fixedly installed on the side wall of the extension column 86. A fall protection net 88 is movably connected to the outer side of the multiple hooks 87. The fall protection net 88 is woven from nylon paracord with high elasticity and stronger toughness. The fall protection net 88 can be hung on the hooks 87 on both sides. In this way, the fall protection net 88 can be unfolded and extended to the outer side of the upright 81. Similarly, the connecting block 84 can be screwed into the base 2 and fixed using the screw head 85. Similarly, an unfolded fall protection net 88 extends out from the lower end of the front of the material hoist body 1. In this way, if the goods fall during the lifting and conveying process, they can be caught by the extended fall protection net 88 and will not fall directly to the ground, thus protecting the integrity of the goods.
[0026] The extension column 86 is made of stainless steel metal pipe and is welded to the outside of the connecting block 84. The side wall of the extension column 86 is provided with multiple rows of curved metal hooks 87. The fall protection net 88 is woven from highly elastic and tough nylon paracord. The fall protection net 88 can be hung on the hooks 87 on both sides. In this way, the fall protection net 88 can be unfolded and extended to the outside of the upright 81. Similarly, the connecting block 84 can be screwed into the base 2 for fixation using the screw head 85. Similarly, an unfolded fall protection net 88 extends out from the lower end of the front of the material hoist body 1. In this way, if the goods fall during the lifting and conveying process, they can be caught by the extended fall protection net 88 and will not fall directly to the ground, thus protecting the integrity of the goods.
[0027] The sprocket drive structure 7 includes a lifting track 71 and movable seats 73. The lifting track 71 is fixedly installed at the front end of the material hoist body 1. The lifting track 71 is composed of a sprocket and a chain on the inner side. The sprocket is driven by a motor to rotate, and the chain rotates along the sprocket to transmit power at the front end of the material hoist body 1. Multiple movable seats 73 are slidably installed on the inner side of the lifting track 71. The lifting track 71 can carry the movable seats 73 fixed on the outer side in a cyclical operation. The outer walls of the multiple movable seats 73 are fixedly connected to a crossbeam 72. The crossbeam 72 is horizontally set on the outer side of the movable seats 73. Multiple forks 74 protrude from the outer side of the crossbeam 72. The forks 74 are used to push and lift the goods. The forks 74 are fixedly installed on the outer side of the crossbeam 72.
[0028] The tops of multiple forks 74 are movably connected to the lower end of the conveyed goods 5. The conveyed goods 5 are movably connected to the end of the material input conveyor belt 3. Multiple round rods are connected to the side of the material unloading conveyor belt 4 and the material input conveyor belt 3 near the forks 74. The gaps between the round rods are just enough to allow the multiple forks 74 to pass through. In this way, after the forks 74 carry the conveyed goods 5 through the ends of the material unloading conveyor belt 4 and the material input conveyor belt 3, the forks 74 will pass normally, while the conveyed goods 5 will remain on the round rods waiting to be conveyed. The conveyed goods 5 are movably connected to the upper part of the other end of the material unloading conveyor belt 4. The multiple forks 74 are slidably set with the rollers at the ends of the material input conveyor belt 3 and the rollers at the other end of the material unloading conveyor belt 4.
[0029] Working principle:
[0030] Safety protection components for logistics lifting devices are used on logistics lifting devices to protect transported goods from damage due to falling or impact.
[0031] Safety fall protection structure of safety protection components for logistics lifting devices:
[0032] The support feet 82, together with the vertical poles 81, can support the material input conveyor belt 3 and the material discharge conveyor belt 4 on both sides of the material elevator body 1. The material input conveyor belt 3 is lower and is used to transport the goods 5 into the machine, while the material discharge conveyor belt 4 on the other side is designed to be higher and is used to transport the goods 5 out of the machine. The mounting holes 83 are opened side by side on the outer wall of the poles 81. The inner side of the mounting holes 83 is provided with threaded grooves, so that the connecting block 84 can be screwed into the mounting hole 83 for fixing using the threaded head 85. The height position of the connecting block 84 on the outside of the poles 81 can be determined according to the height of the mounting hole 83.
[0033] The extension column 86 is made of stainless steel metal pipe and is welded to the outside of the connecting block 84. The side wall of the extension column 86 is provided with multiple rows of curved metal hooks 87. The fall protection net 88 is woven from highly elastic and tough nylon paracord. The fall protection net 88 can be hung on the hooks 87 on both sides. In this way, the fall protection net 88 can be unfolded and extended to the outside of the upright 81. Similarly, the connecting block 84 can be screwed into the base 2 for fixation using the screw head 85. Similarly, an unfolded fall protection net 88 extends out from the lower end of the front of the material hoist body 1. In this way, if the goods fall during the lifting and conveying process, they can be caught by the extended fall protection net 88 and will not fall directly to the ground, thus protecting the integrity of the goods.
[0034] Cargo lifting structure of safety protection components for logistics lifting devices:
[0035] The lifting track 71 is composed of sprockets and chains on the inner side. The sprockets are driven by a motor to rotate, and the chains rotate along the sprockets to transmit power at the front end of the material hoist body 1. Multiple movable seats 73 are slidably installed on the inner side of the lifting track 71. The lifting track 71 can carry the movable seats 73 fixed on the outer side in a cyclical operation. The outer walls of the multiple movable seats 73 are fixedly connected to crossbeams 72. The crossbeams 72 are horizontally set on the outer side of the movable seats 73. Multiple forks 74 protrude from the outer side of the crossbeams 72. The forks 74 are used to push and lift the goods.
[0036] Safety protection components for material lifting and unloading structures in logistics lifting devices:
[0037] Multiple round rods are connected to the side of the material unloading conveyor belt 4 and the material input conveyor belt 3 near the forks 74. The gaps between the round rods are just enough to allow multiple forks 74 to pass through. In this way, after the forks 74 carry the conveyed goods 5 past the ends of the material unloading conveyor belt 4 and the material input conveyor belt 3, the forks 74 will pass through normally, while the conveyed goods 5 will remain on the round rods waiting to be conveyed.
[0038] Example 2:
[0039] Please see Figure 1-6In this embodiment, a safety protection component for a logistics lifting device further includes a cargo high-point limiting transmission structure 6 comprising a protrusion 61 and a limiting groove 64. The protrusion 61 is fixedly installed at the top of the material lifting machine body 1 and vertically welded to the upper part of the material lifting machine body 1. The protrusion 61 can support the horizontal plate 62. The horizontal plate 62 is fixedly installed above the protrusion 61, and side plates 63 are fixedly installed on both sides of the lower end of the horizontal plate 62. The two side plates 63 are welded to both sides of the horizontal plate 62, so that the horizontal plate 62 and the side plates 63 can form an inverted shape above the material lifting machine body 1. The top cover structure has a limiting groove 64 fixedly connected to the inner side of the side plate 63. The limiting groove 64 is made of aluminum alloy with an arc-shaped top on the inner side. Multiple pulleys 65 rotate on the outer wall of the limiting groove 64. In this way, when the material elevator body 1 drives the conveying goods in a circular circulation mode, the conveying goods 5 will be blocked by the limiting groove 64 at the highest point, which restricts the movement trajectory. This can alleviate the problem of the conveying goods being thrown out due to inertia. In order to help contact the conveying goods 5 and reduce friction during conveying, multiple pulleys 65 are rotatably connected to the outer wall of the limiting groove 64 through pins.
[0040] Working principle:
[0041] The protrusion 61 is vertically welded to the top of the material elevator body 1. The protrusion 61 can support the horizontal plate 62. Two side plates 63 are welded to both sides of the horizontal plate 62. In this way, the horizontal plate 62 and the side plates 63 can form an inverted top cover structure on the material elevator body 1. The limiting groove 64 is a canopy with an arc surface on the inner side made of aluminum alloy. Multiple pulleys 65 rotate on the outer wall of the limiting groove 64. In this way, when the material elevator body 1 drives the conveying goods in a circular circulation mode, the conveying goods 5 will be blocked by the limiting groove 64 at the highest point, which restricts the movement trajectory. This can alleviate the problem of the conveying goods being thrown out due to inertia.
