As the core transmission component, the lock chain of hoist is in a high load and frequent friction working state for a long time. To ensure its efficient operation and prolong its service life, regular lubrication of the lock chain is indispensable. At present, many hoists use manual lubricant adding mode, and the operator needs to frequently use oil gun and other tools to smear or inject lubricating oil into the connecting part of each chain link along the length of the lock chain. The worker needs to spend a lot of time shuttling around the hoist, which is time-consuming and laborious.

[0003] In view of the above problems, the utility model provides a kind of hoist lock chain lubricating device. UTILITY MODEL CONTENTS

[0004] The utility model solves the technical problem of overcoming the defects of prior art, and provides a kind of hoist lock chain lubricating device.

[0005] To solve the above technical problems, the utility model adopts the technical scheme of a kind of hoist lock chain lubricating device, which comprises a hoist body and a lock chain body arranged on the side wall of the hoist body. The inner wall of the lock chain body is provided with an oil coating assembly. The oil coating assembly comprises an installation block fixedly connected with the side wall of the hoist body. The outer wall of the installation block is rotatably connected with a control ring. One end of the control ring is fixedly connected with a middle connecting rod. The end of the middle connecting rod away from the control ring is fixedly connected with an outer support block. The outer support block is provided with a movable block on both sides. The movable block is slidably connected with the inner wall of the installation block. A spring band is fixedly connected between the movable block and the inner wall of the installation block. The end of the movable block away from the outer support block is provided with an oil coating block.

[0006] Further, the outer support block is a cylindrical structure, and the side wall of the outer support block is always attached to the movable block.

[0007] Further, the oil coating block is a member made of sponge material.

[0008] Further, the inner wall of the movable block is slidably connected with a sliding block body. One end of the sliding block body is fixedly connected with the oil coating block. The end of the sliding block body away from the oil coating block is fixedly connected with a spring block.

[0009] Further, the spring block is a member made of rubber material, and the spring block is a hemispherical structure.

[0010] Furthermore, a return spring is fixedly connected to the inner wall of the elastic block, and the end of the return spring away from the elastic block is fixedly connected to the bottom of the cavity of the movable block.

[0011] Furthermore, in the relaxed state of the reset spring, the outer wall of the oiled block protrudes out of the inner cavity of the movable block.

[0012] Compared with the prior art, the beneficial effects of this utility model include: lubricating oil is poured onto the oiling block made of sponge material. The oiling block absorbs the lubricating oil. After the oiling block is saturated, the control ring is rotated. The control ring drives the middle connecting rod to rotate synchronously, thereby driving the outer support block to rotate. The contact surface between the outer support block and the movable block rotates from the narrow side to the wide side. During this process, the movable block is pushed outward by the outer support block, thereby driving the oiling block to fit against the chain. Thus, the lubrication operation can be completed during the operation of the chain. The operation is convenient, time-saving and labor-saving. It solves the problem that operators need to frequently use oil guns and other tools to apply or inject lubricating grease to the connection points of each chain link along the chain length, and that workers need to spend a lot of time shuttling around the hoist, which is time-consuming and labor-intensive.

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] Please see Figures 1-4 To address the issue of operators frequently needing to use tools such as grease guns to apply or inject lubricating grease to each link along the chain length, requiring significant time and effort to move around the hoist, the following preferred technical solution is provided:

[0022] A hoist chain lubrication device includes a hoist body 1 and a chain body 2 disposed on the side wall of the hoist body 1. The chain body 2 is precisely mounted on the side wall of the hoist body 1 through a suitable mounting structure. The chain body 2 undertakes the transmission task during the material lifting process. An oiling assembly 3 is provided on the inner wall of the chain body 2. The oiling assembly 3 includes a mounting block 31 fixedly connected to the side wall of the hoist body 1. A control ring 32 is rotatably connected to the outer wall of the mounting block 31. One end of the control ring 32 is fixedly connected to a central connecting rod 33 by a reliable fixed connection method such as welding. The end of the central connecting rod 33 away from the control ring 32 is also rigidly connected to an outer support block 34 by a rigid connection method such as welding. The connection ensures the effective transmission of force, enabling the rotation of the control ring 32 to be precisely converted into the movement of the outer support block 34. Movable blocks 35 are provided on both sides of the outer support block 34. The movable blocks 35 are slidably connected to the inner wall of the mounting block 31. An elastic band is fixedly connected between the movable blocks 35 and the inner wall of the mounting block 31. An oiling block 36 is provided at the end of the movable block 35 away from the outer support block 34. Under the action of the movable block 35, the lubricant stored inside can be evenly and efficiently applied to the inner wall of the chain body 2, achieving all-round and precise lubrication of the chain. The outer support block 34 has a cylindrical structure, and the side wall of the outer support block 34 is always in contact with the movable block 35. The oiling block 36 is a component made of sponge material.

[0023] The inner wall of the movable block 35 is slidably connected to a slider body 37. One end of the slider body 37 is fixedly connected to an oiling block 36. The end of the slider body 37 away from the oiling block 36 is fixedly connected to an elastic block 38. The elastic block 38 is a component made of rubber and has a hemispherical structure. The inner wall of the elastic block 38 is fixedly connected to a return spring 39. The end of the return spring 39 away from the elastic block 38 is fixedly connected to the bottom of the cavity of the movable block 35. When the return spring 39 is relaxed, the outer wall of the oiling block 36 protrudes out of the inner cavity of the movable block 35.

[0024] Specifically, during chain lubrication, workers simply pour lubricating oil onto the sponge-shaped oiling block 36. Once saturated, the oiling block 36 absorbs the oil and rotates the control ring 32. This rotation causes the central connecting rod 33 to rotate synchronously, which in turn rotates the outer support block 34. The contact surface between the outer support block 34 and the movable block 35 rotates from a narrow edge to a wide surface. During this process, the movable block 35 is pushed outward by the outer support block 34, causing the oiling block 36 to adhere to the chain. Lubrication is thus completed during chain operation, making the process convenient, time-saving, and labor-saving. This solves the problem of operators needing to frequently use oil guns and other tools to apply or inject lubricating grease along the chain length, requiring significant time and effort to move around the hoist.

[0025] When the movable block 35 drives the oiling block 36 to adhere to the chain, the oiling block 36, through the reaction force of the pressure, drives the slider body 37 to squeeze the elastic block 38. The elastic block 38 deforms under pressure and presses the return spring 39. Through the reaction force of the return spring 39, it pushes the deformed part of the elastic block 38 outward. The recovery of the elastic block 38 will drive the slider body 37 to push the oiling block 36 outward, so that the oiling block 36 adheres tightly to the chain, ensuring the efficiency of oiling.

[0026] In summary: Workers pour lubricating oil onto the sponge-like oiling block 36. The oiling block 36 absorbs the lubricating oil, and once saturated, it rotates the control ring 32. The control ring 32 drives the central connecting rod 33 to rotate synchronously, which in turn drives the outer support block 34 to rotate. The contact surface between the outer support block 34 and the movable block 35 rotates from a narrow edge to a wide surface. During this process, the movable block 35 is pushed outward by the outer support block 34, causing the oiling block 36 to adhere to the chain. Thus, lubrication is completed during chain operation. When the movable block 35 drives the oiling block 36 to adhere to the chain, the oiling block 36, through the reaction force of the pressure, causes the slider body 37 to squeeze the elastic block 38. The elastic block 38, deformed by pressure, presses against the return spring 39. Through the reaction force of the return spring 39, the deformed part of the elastic block 38 is pushed outward. The recovery of the elastic block 38 causes the slider body 37 to push the oiling block 36 outward, making the oiling block 36 adhere tightly to the chain.
