Description

Technical Field

[0001] This application relates to the field of material handling equipment technology, and in particular to a chain hoist. Background Technology

[0002] Chain elevators are currently used in many places to transport materials such as cement. However, the problem of material backflow has long constrained production efficiency and equipment reliability. Therefore, while adding turntables, sensors, and alarm devices to chain elevators to monitor the stopped state of the driven wheels can provide early warning of equipment failures, it does not fundamentally solve the material leakage problem and further increases the complexity of the equipment and potential points of failure.

[0003] For example, Chinese patent document CN201610647284.2 discloses a plate chain elevator, in which the turntable also includes a turntable body and N blades. The N blades are evenly spaced around the outer edge of the turntable body. The plate chain elevator is also equipped with a control system. The control system includes a control module and a light sensor electrically connected to the control module. The light sensor emits light signals and receives light signals reflected by the blades within the sensing distance.

[0004] In addition, by reducing the gap between the hopper and the receiving tongue, material leakage and residue in the hopper can be reduced. However, if the gap is too small, friction between the hopper and the chain of the chain elevator can cause equipment damage. Therefore, the chain elevator needs to ensure the distance between the hopper and the receiving tongue, while also avoiding technical problems caused by the aforementioned gap. Utility Model Content

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0047] In cement conveying operations using a chain elevator 100, backflow is a common problem. The main reasons are: firstly, cement and other materials impacting the hopper 120 of the chain elevator 100 cause backflow; secondly, incomplete emptying of the hopper 120 causes backflow; and thirdly, excessive gap between the hopper 120 and the receiving tongue 131 of the chain elevator 100 causes backflow. Reducing the gap between the hopper 120 and the receiving tongue 131 can usually reduce backflow during operation. However, if sufficient clearance is not maintained between the hopper 120 and the receiving tongue 131, vibration of the chain 110 can cause collisions between them, damaging the chain elevator 100. Therefore, balancing the gap between the hopper 120 and the receiving tongue 131 of the chain elevator 100 with the backflow problem during operation is an urgent issue to be addressed.

[0048] This application provides a chain hoist 100; please refer to [link / reference]. Figures 1 to 3 The chain elevator 100 includes: a power unit, a chain 110, a bucket 120, and a receiving assembly 130.

[0049] In some embodiments of this application, the power assembly is the power source for the entire chain elevator 100. The power assembly typically includes a drive wheel and a driven wheel, providing the necessary power for the operation of the equipment. The power assembly can employ existing technology, which will not be elaborated here. The chain 110 is connected to the power assembly and performs cyclical motion under its drive. The hopper 120 is connected to the chain 110 and moves with the chain 110, used for loading and transporting materials.

[0050] The main function of the receiving assembly 130 is to receive material from the hopper 120. The receiving assembly 130 includes a receiving tongue 131 and a blocking part 132. The minimum gap between the receiving tongue 131 and the hopper 120 is set within the range of greater than or equal to 20 mm and less than or equal to 40 mm. This reasonable gap setting solves potential problems that may occur during the transfer of material from the hopper 120 to the receiving assembly 130. If the gap is too small, the hopper 120 may collide with the receiving tongue 131 during movement due to the vibration of the chain 110, leading to equipment damage; if the gap is too large, material may spill out. As a more specific solution, the minimum gap between the hopper 120 and the receiving tongue 131 is set to 30 mm. At this gap, collisions between the hopper 120 and the receiving tongue 131 can be effectively avoided, and material spillage can be minimized, improving the stability and reliability of the equipment.

[0051] Although setting a minimum gap between the receiving tongue 131 and the hopper 120 ensures that during the operation of the chain elevator 100, even if the chain 110 vibrates, the chain 110 and the hopper 120 will not come into contact with the receiving tongue 131, thus avoiding equipment damage and minimizing material spillage and backflow, the existence of this gap still results in material backflow during actual operation of the chain elevator 100. This leads to lower equipment efficiency and a higher failure rate. Therefore, a material blocking part 132 is provided to at least partially solve the above-mentioned technical problems. One end of the material blocking part 132 is fixedly connected to the receiving tongue 131, and the other end is close to the hopper 120, with a minimum gap between the material blocking part 132 and the hopper 120 greater than 0 mm. The function of the material blocking part 132 is to reduce the gap between the hopper 120 and the material receiving tongue 131 when the receiving tongue 131 receives material from the hopper 120, thereby solving the technical problem of material return during the operation of the chain elevator 100 and improving the efficiency and accuracy of material receiving.

[0052] In some embodiments of this application, the material blocking part 132 is constructed using several steel wire ropes. The steel wire ropes possess both rigidity and flexibility; however, the material is not limited to steel wire ropes, and other materials with similar properties can be used as substitutes, which will not be elaborated here. One end of the steel wire rope is fixedly connected to the receiving tongue 131, and the other end is close to the hopper 120. The steel wire rope has the characteristics of good flexibility, high strength, good wear resistance, and resistance to rust. It can effectively prevent material from overflowing from the gap between the receiving tongue 131 and the hopper 120 and causing backflow without affecting the normal movement of the hopper 120. At the same time, the cost of the steel wire rope is relatively low, reducing the manufacturing cost of the equipment. Furthermore, the installation and replacement of the steel wire rope are relatively convenient, facilitating equipment maintenance and upkeep.

[0053] In some embodiments of this application, the minimum gap between the wire rope and the hopper 120 is set between 0 and 5 mm. This gap range allows one end of the wire rope to be close to the hopper 120, maximizing the prevention of material overflow. When the gap is within this range, it reduces friction between the wire rope and the hopper 120, ensuring that even if friction occurs, it does not affect the movement of the hopper 120. Simultaneously, it effectively prevents material from leaking out of the gap between the wire rope and the hopper 120, improving the accuracy and efficiency of material receiving.

[0054] In some embodiments of this application, the receiving assembly 130 further includes a pressure plate 140, which is fixedly connected to the wire rope, and the wire rope is disposed between the pressure plate 140 and the receiving tongue 131. The function of the pressure plate 140 is to firmly fix the wire rope to the receiving tongue 131, preventing the wire rope from loosening or shifting during use. Through the fixing by the pressure plate 140, the wire rope can always remain in the correct position, effectively playing its role in resisting material movement. At the same time, this structural design makes the installation and adjustment of the wire rope more convenient, improving the assembly efficiency of the equipment.

[0055] In some embodiments of this application, the diameter of the wire rope is set to 8-12 mm, and the wire rope is positioned on the side of the receiving tongue 131 near the top of the chain elevator 100. A suitable wire rope diameter ensures that the wire rope has sufficient strength and flexibility, effectively blocking material without being too stiff and affecting the movement of the hopper 120. Positioning the wire rope on the side of the receiving tongue 131 near the top of the chain elevator 100 allows the material to contact the wire rope first during its descent, further improving the material blocking effect.

[0056] In some embodiments of this application, several steel wire ropes are fixed at equal intervals to the receiving tongue 131. This equidistant fixing method ensures that the material is uniformly blocked by the steel wire ropes during the receiving process, avoiding the problem of local material spillage. The equidistantly distributed steel wire ropes can form a uniform material-blocking barrier, improving the uniformity and stability of material reception.

[0057] In some embodiments of this application, the pressure plate 140 and the receiving tongue 131 are connected by threads, and a rubber gasket is provided between the pressure plate 140 and the receiving tongue 131. The threaded connection makes the connection between the pressure plate 140 and the receiving tongue 131 more secure and facilitates installation and disassembly. The rubber gasket serves as a buffer and seal, reducing friction and vibration between the pressure plate 140 and the receiving tongue 131, thus extending the service life of the equipment. Simultaneously, the rubber gasket also prevents material leakage from the connection between the pressure plate 140 and the receiving tongue 131, improving the equipment's sealing performance.

[0058] In this application, the width of the pressure plate 140 is less than half the axial length of the wire rope, and the height of the pressure plate 140 is greater than the diameter of the wire rope. This dimensional design allows the pressure plate 140 to effectively fix the wire rope without affecting its normal operation. The width of the pressure plate 140 being less than half the axial length of the wire rope ensures that the wire rope has sufficient space to perform its material-blocking function; the height of the pressure plate 140 being greater than the diameter of the wire rope ensures that the pressure plate 140 can firmly press down on the wire rope and prevent it from loosening. At the same time, the pressure plate 140 acts like a threshold, preventing some material from entering the receiving tongue 131 and then returning to the hopper 120 or the equipment interior due to equipment vibration or other reasons, thus preventing material backflow.

[0059] In some embodiments of this application, the width of the receiving tongue 131 is greater than the width of the hopper 120, the width of the blocking part 132 is greater than the width of the hopper 120, and the width of the pressure plate 140 is also greater than the width of the hopper 120. This width design ensures that the material in the hopper 120 can be completely received by the receiving assembly 130 during its descent, preventing material from overflowing from both sides of the receiving assembly 130. By increasing the width of each part of the receiving assembly 130, the comprehensiveness and reliability of material reception are improved, further enhancing the working efficiency of the equipment.

[0060] In summary, the chain elevator 100 of the present invention, through reasonable structural design and parameter settings, effectively solves the problem of material return during the material transfer process, improves the stability, reliability and working efficiency of the equipment, and has significant technical effects and economic benefits.
