Description

Technical Field

[0001] This utility model relates to the field of logistics lifting equipment technology, specifically a limiting structure for logistics lifting equipment. Background Technology

[0002] Logistics, originally meaning "physical distribution" or "goods delivery," is a part of supply chain activities. It is the process of planning, implementing, and controlling the efficient and low-cost flow and storage of goods, services, and related information from production sites to consumption sites in order to meet customer needs. Logistics is centered on warehousing and promotes the synchronization of production and the market. Logistics requires the use of lifting devices to transport and classify goods to change the direction of transport.

[0003] For example, the authorization announcement number "CN218144033U" is for a conveying and logistics lifting machine, which has the function of conveying materials to different areas. It is also integrated into a whole, realizing the conveying and lifting of goods in one process, making the device more adaptable and reducing the investment cost. Existing conveying and logistics lifting machines require the conveying device to move the goods to a certain position and then lift them vertically to a higher position. Therefore, it is necessary to ensure that the goods are in a relatively stable area of ​​the lifting plate when they are moved laterally to the lifting position. Generally, conveying and logistics lifting machines rely on manual operation to complete the lateral conveying limit operation. However, manual operation is not only labor-intensive, but also prone to accidents caused by people putting their hands into the lifting machine, which reduces the effectiveness of the conveying and logistics lifting machine.

[0004] Meanwhile, existing conveyor lifting equipment requires vertical lifting of goods to higher places for transfer. During the lifting process, the height of the goods needs to be limited. If the height of the goods is exceeded, a height difference will occur between the lifting plate and the discharge plate, which can easily cause the goods to be bumped and damaged. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of poor performance and easy damage to goods caused by existing conveying and logistics lifting equipment, and to propose a limiting structure for logistics lifting equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a limiting structure for a logistics lifting device, including a support frame, a discharge platform, and a top box. The top box is fixedly installed at the top of the support frame, the discharge platform is fixedly installed on the upper side of the support frame, a material conveying structure is provided on the lower side of the support frame, a lateral limiting structure for conveying goods is provided at the bottom of the inner side of the support frame, a goods lifting structure is provided on the inner side of the support frame, and a vertical limiting structure for lifting goods is provided on the upper inner wall of the support frame.

[0008] Preferably, the material conveying structure includes vertical columns and a loading rack. The loading rack is fixedly installed on the lower end of the outer wall of the supporting frame. Multiple vertical columns are fixedly connected to the bottom end of the loading rack. Slide grooves are fixedly opened on the side wall of the loading rack. Side plates are slidably connected to the inner side of two slide grooves. Iron pallets are fixedly connected to the inner side of two side plates. Multiple delivery rollers are rotatably connected to the inner side of the loading rack.

[0009] Preferably, the cargo conveying lateral limiting structure includes a crossbeam and a lifting frame. The crossbeam is fixedly installed on the inner bottom end of the supporting frame. A vertical rod is fixedly installed on the top of the crossbeam. A tray is fixedly installed on the top of the multiple vertical rods. An electromagnet is fixedly installed on the inner side of two trays. A lifting frame is movably connected above the two trays. Multiple transfer rollers are rotatably installed on the inner side of the lifting frame.

[0010] Preferably, the cargo lifting vertical limiting structure includes a positioning frame and a damping rod. The positioning frame is fixedly installed on the upper inner wall of the support frame. The damping rod is slidably connected to the inner side of the positioning frame. An extension frame is fixedly connected to the upper part of the positioning frame. A screw is threadedly connected to the inner side of the extension frame. A crank is fixedly connected to the top end of the screw. The bottom end of the screw is rotatably connected to the top end of the damping rod.

[0011] Preferably, one end of the lifting frame is connected to the end of the feeding frame, the other end of the lifting frame is connected to the end of the discharge platform, and the top edge of the lifting frame is movably connected to the bottom end of the damping rod.

[0012] Preferably, the cargo lifting structure includes counterweights and a traction machine. Two counterweights are slidably disposed on both sides of the inner wall of the support frame. Pulling steel cables are fixedly connected to the top of the two counterweights. The traction machine is fixedly installed on the inner side of the top box. The outer side of the pulley of the traction machine is slidably connected to the pulling steel cables. The other ends of the plurality of pulling steel cables are fixedly connected to the upper part of the outer wall of the lifting frame.

[0013] Preferably, the outer wall of the support frame is fixedly connected with a fall arrestor.

[0014] The limiting structure for logistics lifting equipment proposed in this utility model has the following advantages: the electromagnet is made of a magnet that can generate a strong magnetic attraction force when energized. When the electromagnet is energized, it will generate an attraction force. When the iron tray that has slid to the top of the lifting frame comes into contact with the electromagnet, it will be attracted and restricted, and will not continue to move forward. This completes the limiting of the lateral transport of logistics goods. This allows the goods to be positioned more accurately during the logistics lifting process, and does not require manual adjustment. It is safe and reliable, and improves the effectiveness of the limiting structure for logistics lifting equipment.

[0015] The screw can be rotated by manually turning the crank handle. The screw will adjust the height of the damping rod inside the positioning frame, and also adjust the height of the contact point between the bottom of the damping rod and the edge of the lifting frame. When the lifting frame is lifted up to the level of the discharge platform, the bottom of the damping rod will push against the edge of the lifting frame. The contraction of the damping rod will reduce the impact force on the lifting frame and also limit the vertical height. This restricts the height of the lifting frame carrying the logistics goods, reduces the collision caused by the height difference of the goods during discharge, protects the goods and meets the conveying requirements.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] Example 1:

[0025] Please see Figure 1-6 In this embodiment, a limiting structure for a logistics lifting device includes a support frame 1, a discharge platform 2, and a top box 4. Both the top box 4 and the support frame 1 are welded from stainless steel. The top box 4 is used to hold the traction machine equipment, while the support frame 1 is vertically fixed to the ground of the logistics lifting workshop. The top box 4 is fixedly installed at the top of the support frame 1. The discharge platform 2 is fixedly installed on the upper side of the support frame 1. The discharge platform 2 has multiple rotatable rollers on its inner side, so that when the goods are lifted to the level of the discharge platform 2, they can be transported outward. A material conveying structure 5 is provided on the lower side of the support frame 1. A horizontal limiting structure 6 for conveying goods is provided at the bottom of the inner side of the support frame 1. A goods lifting structure 7 is provided on the inner side of the support frame 1. A vertical limiting structure 8 for lifting goods is provided on the upper part of the inner wall of the support frame 1.

[0026] The material conveying structure 5 includes vertical columns 51 and a feeding rack 52. The feeding rack 52 is fixedly installed on the lower end of the outer wall of the supporting frame 1. The feeding rack 52 is used for horizontally conveying goods into the supporting frame 1. Multiple vertical columns 51 are fixedly connected to the bottom end of the feeding rack 52, and the vertical columns 51 support the horizontal feeding rack 52 on the ground. The side walls of the feeding rack 52 are fixedly provided with sliding grooves 53. The two sliding grooves 53 can restrict the horizontal sliding of the side plates 55. The inner sides of the two sliding grooves 53 are slidably connected to the side plates 55. A fixed iron pallet 54 is attached, and the goods to be lifted are placed on top of the iron pallet 54. The iron pallet 54 is made of iron and can be attracted and fixed by an electromagnet 66 through magnetic force. Then, a motor drives multiple delivery rollers 56 to rotate inside the loading rack 52. The rotating delivery rollers 56 push the iron pallet 54 above to carry the goods into the inner side of the support frame 1, and the iron pallet 54 slides the goods into the lifting frame 64 in preparation for lifting. Multiple delivery rollers 56 are rotatably connected to the inner side of the loading rack 52.

[0027] The lateral limiting structure 6 for cargo conveying includes a crossbeam 61 and a lifting frame 64. The crossbeam 61 is fixedly installed on the inner bottom of the supporting frame 1. A vertical rod 62 is fixedly installed above the crossbeam 61, supporting the vertical rod 62 upwards. The vertical rod 62 supports the topmost pallet 63 to be flush with the top surface of the loading rack 51. Pallets 63 are fixedly installed at the top of multiple vertical rods 62. When the lifting frame 64 descends to receive and lift materials, the bottom of the lifting frame 64 will land on the pallet 63. The pallet 63 serves to support and connect the ends of the loading rack 51 and the lifting frame 64. Electromagnets 66 are fixedly installed on the inner sides of the two pallets 63. The electromagnets 66 are made of magnets that can generate a strong magnetic attraction when energized. When the electromagnets 66 are energized, they generate attraction, and the iron pallet 54 sliding above the lifting frame 64 contacts the electromagnet. The iron pallet 66 is then attracted and prevented from moving forward, thus limiting the lateral transport of the goods. A lifting frame 64 is movably connected above the two pallets 63. Multiple transfer rollers 65 are rotatably mounted on the inner side of the lifting frame 64. These rollers 65 can also be driven to rotate by a motor. The transfer rollers 64 transport the iron pallet to the discharge platform 2, completing one lifting process. One end of the lifting frame 64 is connected to the end of the loading rack 51, and the other end is connected to the end of the discharge platform 2. The top edge of the lifting frame 64 is movably connected to the bottom end of the damping rod 85. This structure effectively limits the lateral transport of the goods, ensuring precise positioning during the lifting process without the need for manual adjustment, thus improving safety, reliability, and the effectiveness of the limiting structure in the lifting equipment.

[0028] The cargo lifting structure 7 includes counterweights 71 and a traction machine 73. Two counterweights 71 are slidably mounted on both sides of the inner wall of the support frame 1. The counterweights 71 are made of solid metal steel plates and have a large weight, enabling them to lift cargo. Pulling cables 72 are fixedly connected to the top of the two counterweights 71. The pulling cables 72 are made of high-strength, non-breakable steel wire ropes wound together. The traction machine 73 is fixedly installed inside the top box 4. The traction machine 73 represents a relatively mature technology at present, integrating a motor, brake, coupling, gearbox, traction sheave, frame, and guide wheel. With numerous components, the traction machine 73, after being powered on and started, uses the friction of the traction wheel to generate traction. After being reduced in speed by a reducer, it pulls the traction wheel to rotate, thereby realizing the lifting of the lifting frame 64 and the counterweight 71. One end of the pulling steel cable 72 is connected to the lifting frame 64, and the other end of the pulling steel cable 72 is connected to the counterweight 71. The motor drives the traction wheel to rotate, driving the pulling steel cable 72 to complete the vertical transportation task of the lifting frame 64. The outer side of the pulley of the traction machine 73 is slidably connected to the pulling steel cable 72, and the other end of multiple pulling steel cables 72 is fixedly connected to the upper part of the outer wall of the lifting frame 64.

[0029] A fall arrestor plate 3 is fixedly connected to the outer wall of the support frame 1. The fall arrestor plate 3 is made of multiple metal wire meshes welded to the outer wall of the support frame 1. The fall arrestor plate 3 restricts the occurrence of the lifted goods falling to the outside.

[0030] Working principle:

[0031] Limiting structures for logistics lifting equipment are used in the direction of cargo transportation. They can limit the lateral movement and vertical lifting position of the cargo, ensuring a smoother and more precise logistics transportation process.

[0032] The main structure of the logistics lifting equipment is as follows:

[0033] Both the top box 4 and the support frame 1 are welded from stainless steel. The top box 4 is used to hold the traction machine equipment, while the support frame 1 is vertically fixed to the ground of the logistics lifting workshop. The top box 4 is fixedly installed on the top of the support frame 1, and the discharge platform 2 is fixedly installed on one side above the support frame 1. There are multiple rotatable rollers on the inner side of the discharge platform 2, so that when the goods are lifted to the level of the discharge platform 2, they can be transferred outward.

[0034] Low-level loading structure for goods in the limiting structure of logistics lifting equipment:

[0035] The loading rack 52 is used to horizontally transport goods into the support frame 1 for feeding. The vertical column 51 supports the horizontal loading rack 52 and fixes it on the ground. The side slides 53 can restrict the horizontal sliding of the side plate 55. The iron pallet 54 is used to place the goods to be lifted. Then, the motor drives multiple delivery rollers 56 to rotate inside the loading rack 52. The rotating delivery rollers 56 push the iron pallet 54 above to carry the goods into the support frame 1. The iron pallet 54 slides the goods into the lifting frame 64 to prepare for lifting.

[0036] Lateral limiting lifting structure for logistics lifting equipment:

[0037] The crossbeam 61 supports the vertical rod 62 upwards, and the vertical rod 62 supports the top plate 63 at the same height as the top surface of the loading rack 51. When the lifting frame 64 falls to prepare for receiving and lifting materials, the bottom of the lifting frame 64 will land on the plate 63. The plate 63 serves to support and connect the ends of the loading rack 51 and the lifting frame 64. The electromagnet 66 is made of a magnet that can generate a strong magnetic attraction when energized. When the electromagnet 66 is energized, it will generate attraction. When the iron pallet 54 slides above the lifting frame 64 comes into contact with the electromagnet 66, it will be attracted and restricted and will not continue to move forward. This completes the limit of the horizontal transport of logistics goods. When lifting is required, the working of the electromagnet 66 will be turned off and the magnetic attraction will be canceled, so the iron pallet 54 will not be restricted from rising. The transfer roller 65 can also be driven to rotate by a motor. The transfer roller 64 transports the iron pallet to the discharge platform 2, realizing one lifting process.

[0038] The logistics lifting structure in the limit structure of logistics lifting equipment:

[0039] The counterweight 71 is made of solid metal steel plate and has a large weight to achieve the purpose of lifting and pulling goods. The pulling cable 72 is made of high-strength steel wire rope that is not easy to break and is intertwined. The traction machine 73 is a relatively mature technology at present. It integrates many components such as motor, brake, coupling, gearbox, traction sheave, frame and guide wheel. After the traction machine 73 is connected to the power and started, it uses the friction of the traction sheave to generate traction. After the speed is changed by the reducer, it pulls the traction sheave to rotate, thereby realizing the lifting and lowering of the lifting frame 64 and the counterweight 71. One end of the pulling cable 72 is connected to the lifting frame 64 and the other end is connected to the counterweight 71. The motor drives the traction sheave to rotate, drives the pulling cable 72 and then completes the vertical transportation task of the lifting frame 64.

[0040] Example 2:

[0041] Please see Figure 1-6In this embodiment, a limiting structure for a logistics lifting device includes a vertical limiting structure 8 for cargo lifting, comprising a positioning frame 81 and a damping rod 85. The positioning frame 81 is fixedly installed on the upper inner wall of the support frame 1. The positioning frame 81 is made of aluminum alloy and is fixed inside the support frame 1 by screws. The damping rod 85 is slidably connected to the inner side of the positioning frame 81. The damping rod 85 can be a pneumatic damper, which provides damping and buffering through the principle of air compression. An extension frame 82 is fixedly connected above the positioning frame 81. The extension frame 82 vertically supports the screw 84 upwards. The inner thread of the extension frame 82... A screw 84 is connected, and a crank 83 is fixedly connected to the top of the screw 84. By manually rotating the crank 83, the screw 84 can be rotated. The screw 84 will adjust the height position of the damping rod 85 inside the positioning frame 81, and can also adjust the height of the contact position between the bottom of the damping rod 85 and the edge of the lifting frame 64. When the lifting frame 64 is lifted up to the same level as the discharge platform 2, the bottom of the damping rod 85 will push against the edge of the lifting frame 64. The contraction and buffering of the damping rod 85 reduces the impact force of the lifting frame 64, while also achieving vertical height limitation. The bottom of the screw 84 is rotatably connected to the top of the damping rod 85.

[0042] Working principle:

[0043] The positioning frame 81 is made of aluminum alloy and is fixed inside the support frame 1 by screws. The damping rod 85 is a pneumatic damper that uses the principle of air compression for damping. The extension frame 82 supports the screw 84 vertically. The screw 84 can be rotated by manually rotating the crank handle 83. The screw 84 will adjust the height of the damping rod 85 inside the positioning frame 81 and also adjust the height of the contact point between the bottom of the damping rod 85 and the edge of the lifting frame 64. When the lifting frame 64 is lifted up to be flush with the discharge platform 2, the bottom of the damping rod 85 will push against the edge of the lifting frame 64. The contraction of the damping rod 85 reduces the impact force of the lifting frame 64 and also limits the vertical height.
