Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically a continuous elevator that provides stable conveying. Background Technology

[0002] A continuous elevator is a vertical conveying device that operates continuously. It is used to connect production lines and assembly lines on different floors to transport materials between them. Continuous elevators lift and lower materials continuously without the need for empty diaphragms, thus reducing operating time and improving the efficiency of material transport between floors.

[0003] An investigation revealed a Chinese utility model disclosure for a high-efficiency continuous elevator (publication number: CN219859286U), comprising a discharge elevator, a transfer conveyor belt, a loading elevator, and a cargo partition. Both the discharge and loading elevators are equipped with transfer conveyor belts at their upper ends. Goods on the cargo partition are transported to the transfer conveyor belt via the loading elevator, and the discharge elevator receives the lifted goods via the transfer conveyor belt. This utility model uses the loading elevator to lift and transport goods to the transfer conveyor belt, and then lowers them to the desired area via the discharge elevator. The loading and discharge elevators operate simultaneously, enabling simultaneous lifting and lowering of goods, as well as loading and unloading. This ensures that the return stroke of the partition does not disrupt the working cycle, resulting in higher transportation efficiency, a compact structure, less space occupation, lower operating costs, and greater safety and reliability for transporting goods at heights.

[0004] Although the aforementioned patent, through the installation of discharge elevators, transfer conveyor belts, loading elevators, and cargo partitions, makes the high-altitude transportation of goods relatively safe and reliable, if the conveyor belt experiences abnormal conditions such as slippage or overturning during the transportation of goods to higher ground, the truck at the top is very likely to lose balance and fall due to sudden jerking or reverse movement. This will not only cause serious damage to the goods and lead to economic losses, but may also trigger a series of safety accidents, endangering the safety of surrounding personnel and equipment, and bringing great negative impact to the entire operation process.

[0005] Therefore, this utility model provides a continuous elevator with stable conveying to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a hoist, such as Figures 1 to 5As shown, the system includes an overall frame 1. A belt conveyor mechanism 2 is placed on one side of the overall frame 1. The belt conveyor mechanism 2 consists of a guard, a belt, and a motor. A load-bearing mechanism 3 is bolted to both sides of the inner wall of the overall frame 1. The load-bearing mechanism 3 consists of a support plate, a cargo plate, and a curved chain. A lifting mechanism 4 is fixedly installed on the other side of the inner wall of the overall frame 1. The lifting mechanism 4 mainly consists of an idler wheel, a sprocket, a chain, and a chain support plate. A shaft 5 is connected through one side of the idler wheel. Both ends of the shaft 5 are connected through limit plates 6. A circular hole 601 is opened at the top of one side of the limit plate 6. A vertical support is provided on the side of the limit plate 6 near the circular hole 601. The inner arc surface of the strip hole 602 and the round hole 601 is movably connected to the shaft 5. The outer arc surface of the vertical strip hole 602 is slidably engaged with the connecting shaft seat 7. There are two limiting plates 6, which are distributed in a mirror symmetrical manner on both sides of the overall frame 1. The middle of one side of the connecting shaft seat 7 is connected to the hinge rod 701. One end of the hinge rod 701 is connected to the connecting shaft seat 7 on the other side. The middle of the outer arc surface of the hinge rod 701 is connected to the cam gear 8. The outer arc surface of the cam gear 8 is provided with a recessed groove 801 between the serrations. The side of the shaft 5 near the idler wheel is connected to the main ring body 9. Both sides of the main ring body 9 are provided with annular protrusions 901, which are placed on the surface of the shaft 5.

[0028] In the claims of this utility model, the belt conveyor mechanism 2 is driven by a motor to rotate the belt and achieve the initial transport of goods. The support plate and cargo plate of the carrying mechanism 3 are equipped with a core function of providing stable and reliable support for the goods transported by the belt. After the goods smoothly enter the interior of the overall frame 1, the motor starts and drives the idler wheel in the lifting mechanism 4 to start rotating. Since there is a rigid connection between the idler wheel and the sprocket on one side, the rotation of the idler wheel can synchronously drive the sprocket to rotate, thereby driving the vertically upward chain to run stably, and finally achieving the smooth lifting of the cargo plate, ensuring that the goods can be efficiently transported to the target height along the predetermined path.

[0029] Of particular note is that the bent plate chain rotor of the bearing mechanism 3 and the idler wheel of the lifting mechanism 4 are connected by interlocking, which ensures the stability of the transport of goods during the warehousing and outgoing processes and effectively reduces the risk of damage to goods due to shaking and bumping. At the same time, chain support bars are set on the overall frame 1, which can provide stable support during the high-speed operation of the chain, greatly reduce the frictional loss between the chain and the frame, and significantly reduce the noise generated by friction, creating a quiet and efficient environment for the equipment to operate.

[0030] The equipment operates in a continuous mode. Under the premise that the operating speeds of the belt conveyor 2, the carrying mechanism 3, and the lifting mechanism 4 are matched, the goods are smoothly transferred from the belt conveyor 2 to the continuous elevator. Then, relying on the motor to provide power and with the reliable transmission between the chain and the sprocket, the carrying mechanism 3 and the lifting mechanism 4 are driven to work together in an orderly manner, so as to successfully achieve the task of efficiently lifting the goods and meet the vertical transportation needs of goods under various complex working conditions.

[0031] A braking assembly 10 is connected through the side of the shaft 5 near the main ring body 9. The braking assembly 10 includes a ratchet 101 that is connected through the surface of the shaft 5. A mounting wheel 102 is connected to the side of the shaft 5 near the ratchet 101. A through hole is provided in the middle of the side surface of the mounting wheel 102. A torsion spring 103 is fixedly installed in the through hole on the side of the mounting wheel 102. One end of the torsion spring 103 has an extension. The extension on one side of the torsion spring 103 is placed at the serration on the outer arc surface of the ratchet 101. A pawl 104 is fixedly installed at one end of the torsion spring 103. One end of the pawl 104 is movably engaged at the serration on the outer arc surface of the ratchet 101. A protruding section 105 is provided in the middle of the side surface of the ratchet 101. The middle of one side of the protruding section 105 is connected through the shaft 5. A sleeve 106 is fixedly connected through the outer arc surface of the protruding section 105. One end of the sleeve 106 is connected through the recessed groove 801 and engaged.

[0032] Meanwhile, limiting plates 6 are symmetrically installed on both sides of the shaft 5 to further enhance the stability of the transportation process. A connecting shaft seat 7 is slidably connected in the vertical strip hole 602 opened below one side of the limiting plate 6. The connecting shaft seats 7 are distributed on both sides of the overall frame 1, and the hinge rod 701 can be firmly installed on the connecting shaft seats 7 on both sides. A cam gear 8 is installed in the hinge rod 701. The cam gear 8 is adapted to the top sleeve rod 106, and the sleeve rod 106 is connected to the ratchet 101. Since the ratchet 101 is directly installed on the shaft 5, this ensures that the entire device can cooperate with the hoist and operate smoothly.

[0033] Under normal unidirectional motion, the pawl 104 remains in contact with the teeth of the ratchet 101 under the force of the torsion spring 103. When the chain rotates in the forward direction, the pawl 104 will slide smoothly along the back of the teeth of the ratchet 101. During this process, the force applied by the pawl 104 to the ratchet 101 will not hinder the forward rotation of the ratchet 101, so that the ratchet 101 can rotate continuously in the preset direction without any obstruction, ensuring the stable operation of the hoist.

[0034] However, in the event of an emergency or an abnormal situation such as the idler wheel flipping over, causing an external force to attempt to drive the ratchet 101 to rotate in the opposite direction, the pawl 104 will firmly engage with the teeth of the ratchet 101 due to its shape being compatible with the ratchet 101. Since the shape of the pawl 104 matches the shape of the teeth of the ratchet 101, the two can form an effective engagement, thereby generating strong resistance to prevent the ratchet 101 from moving in the opposite direction, effectively ensuring the safety of the hoist and the transported goods.

[0035] Furthermore, after the connecting sleeve 106 of the protruding section 105 stops rotating, it will tightly abut against the recessed groove 801 set on the outer arc surface of the cam gear 8, further enhancing the braking effect and ensuring the smooth and safe operation of the hoist from multiple directions.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
