Description

Technical Field

[0001] This utility model relates to the field of cement handling support technology, and in particular to an adjustable support mechanism for cement handling. Background Technology

[0002] Cement: A powdered hydraulic inorganic binder. When mixed with water, it forms a paste that hardens in air or, even better, in water, and can firmly bind materials such as sand and stone together. For a long time, cement has been widely used as an important binder in civil engineering, water conservancy, and national defense projects. However, the large-scale use of cement has also brought some challenges to its handling. Currently, cement is transported by large trucks and then moved by conveyors. Adjustable support mechanisms are installed under the conveyors to adjust their height and position to suit different usage conditions.

[0003] However, in practical applications, some unresolved issues remain. The following are some common problems with adjustable support mechanisms used in cement handling: Typically, the conveyor is adjusted using the extension and retraction of hydraulic cylinders. During cement handling, cement dust flies around and adheres to the surface of the hydraulic cylinder output shaft, accelerating component wear. The high hardness of cement dust particles causes friction with the output shaft surface, leading to wear, scratches, and even localized peeling of the metal layer, disrupting lubrication. Particle adhesion also damages the oil film integrity, increasing movement resistance, and over time may cause abnormal noise or jamming, even resulting in decreased sealing performance and oil contamination. Utility Model Content

[0005] Therefore, the problem to be solved by this utility model is how to solve the problem that cement dust will fly and adhere to the surface of the hydraulic cylinder output shaft during the cement handling process, which will accelerate the wear of the parts. The cement dust particles have high hardness and will rub against the surface of the output shaft, causing wear, scratches or even local peeling of the metal layer, destroying the lubrication conditions. Particle adhesion will destroy the integrity of the oil film, increase the resistance of movement, and may cause abnormal noise or jamming in the long term, and even cause a decrease in sealing performance and oil contamination.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides an adjustable support mechanism for cement handling. The adjustable support mechanism for cement handling includes a conveyor 100 and a support assembly 200. The conveyor 100 can handle cement, and the support assembly 200 can provide adjustable support for the conveyor 100.

[0032] Specifically, the support component 200 is fixedly connected to the bottom of the conveyor 100, including a hydraulic cylinder 201 located below the conveyor 100. The bottom of the hydraulic cylinder 201 is fixedly connected to a base 202, and the top of the hydraulic cylinder 201 is fixedly connected to a round block 203, which is also fixedly connected to the bottom of the conveyor 100. The round block 203 is fixedly connected to the conveyor 100 by bolts, and the upper end of the output shaft of the hydraulic cylinder 201 is fixedly connected to the round block 203 by bolts.

[0033] A ring 204 is fitted on the outer surface of the hydraulic cylinder 201. Insert rings 205 are inserted into the bottom of the block 203 and the top of the ring 204. Both the block 203 and the ring 204 have annular grooves that mate with the insert rings 205. The end of the insert ring 205 that is inserted into the annular groove is chamfered to facilitate the movement of the locking block 208b when it is inserted and fixed. When the locking block 208b rebounds, the insert ring 205 is rotated to insert the locking block 208b into the slot 207, thereby limiting and fixing the insert ring 205, and then installing and fixing the telescopic sleeve 206. The same principle applies to disassembly, making it more convenient.

[0034] A telescopic sleeve 206 is fixedly connected to the insert ring 205 and is fitted onto the surface of the hydraulic cylinder 201. The telescopic sleeve 206 protects the output shaft of the hydraulic cylinder 201 from telescopic movement, preventing cement dust from adhering to the surface of the output shaft and causing wear and damage during telescopic movement, as well as from entering the hydraulic cylinder 201 and causing damage. A slot 207 is formed on the outer surface of the insert ring 205. The slot 207 is shaped from deep to shallow. By rotating the insert ring 205, the slot 207 can be rotated, allowing the locking block 208b to be inserted into the slot 207 to fix the insert ring 205. Conversely, when rotating in the opposite direction, the locking block 208b can be disengaged from the slot 207 on the insert ring 205 to release the fixation.

[0035] Both the circular block 203 and the circular ring 204 are equipped with fixing parts 208, which cooperate with the slot 207. The fixing parts 208 can fix the insert ring 205. The hydraulic cylinder 201 is equipped with a lubrication mechanism 210, which is located on the surface of the circular ring 204. The lubrication mechanism 210 can lubricate the output shaft surface of the hydraulic cylinder 201, which plays a protective role. In addition, when the insert ring 205 and the telescopic sleeve 206 are removed from the hydraulic cylinder 201 during maintenance, the lubrication is automatically shut off to avoid lubricating oil leakage and waste during maintenance.

[0036] Example 2

[0037] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the fastener 208 includes a first groove 208a formed in the circular block 203 and the circular ring 204. A locking block 208b is slidably connected in the first groove 208a, and one end of the locking block 208b extends into the inner cavity of the locking groove 207. The locking block 208b is inserted into the locking groove 207 and has an inclined surface at one end. When the inserting ring 205 is inserted into the ring groove, it is convenient to squeeze the locking block 208b to make it move. The locking groove 207 cooperates with the locking block 208b.

[0039] A first guide block 208c is fixedly connected to the locking block 208b and is slidably connected to the first groove 208a. The first guide block 208c guides and limits the locking block 208b. A first spring 208d is fixedly connected to the first guide block 208c and one end of the spring is fixedly connected to the inner wall of the first groove 208a. The first spring 208d is compressed when the insert ring 205 presses and moves the locking block 208b, thus providing a force for the locking block 208b to reset at all times. When the insert ring 205 is rotated so that the locking block 208b is aligned with the locking groove 207, it is gradually inserted into the locking groove 207 under the action of the elastic force, thus limiting the insertion ring 205.

[0040] The lubrication mechanism 210 includes a lubricating oil tank 210a fixedly connected to the hydraulic cylinder 201. The bottom of the lubricating oil tank 210a is connected to a connecting pipe 210b, which connects the lubricating oil tank 210a to the lubricating component 210c. The lubricating oil tank 210a is fixedly connected to the hydraulic cylinder 201 by a support rod. One end of the connecting pipe 210b is connected to the lubricating component 210c and is fixedly connected to the hydraulic cylinder 201. An opening and closing component 210d is installed on the connecting pipe 210b and is disposed on the surface of the ring 204. The opening and closing operation of the connecting pipe 210b is realized by the opening and closing component 210d, thereby realizing the lubrication operation and the shutdown of lubrication.

[0041] The lubricating component 210c includes a hollow ring 210c-1 fixedly connected to the hydraulic cylinder 201. A channel 210c-2 is opened on the inner surface of the hollow ring 210c-1 and communicates with the inner cavity of the hollow ring 210c-1. The lubricating oil in the hollow ring 210c-1 wets the cotton column 210c-3 through the channel 210c-2, and then provides lubricating oil to the ball 210c-4 through the cotton column 210c-3. The end of the connecting pipe 210b away from the lubricating oil tank 210a is connected to the inner cavity of the hollow ring 210c-1.

[0042] The channel 210c-2 is filled with cotton columns 210c-3. There are several channels 210c-2, and the number of cotton columns 210c-3 and ball bearings 210c-4 is the same. They are arranged in a circumferential array on the hollow ring 210c-1. The ball bearings 210c-4 are rotatably connected in the channel 210c-2, and they are in contact with the cotton columns 210c-3 and the output shaft surface of the hydraulic cylinder 201, respectively. Through the arrangement of the ball bearings 210c-4, when the output shaft of the hydraulic cylinder 201 extends or retracts, it can drive the ball bearings 210c-4 to rotate, thereby transferring the lubricating oil on the ball bearings 210c-4 to the output shaft for lubrication. Lubrication can be completed by extension or retraction without manual operation.

[0043] The opening and closing component 210d includes a second groove 210d-1 formed within the annulus 204. An opening and closing block 210d-2 is slidably connected within the second groove 210d-1, and its upper end is slidably connected to the connecting pipe 210b. A sealing ring is provided between the opening and closing block 210d-2 and the connecting pipe 210b to seal them and prevent leakage of lubricating oil. A pressing block 210d-3 is slidably connected within the second groove 210d-1, and its two ends are in contact with the insert ring 205 and the surface of the opening and closing block 210d-2, respectively. The ends of the pressing block 210d-3 and the opening and closing block 210d-2 that are close to each other are both trapezoidal. Through this mechanism, when the pressing block 210d-3 moves to press the opening and closing block 210d-2 to move, the opening and closing block 210d-2 can be moved to open the connecting pipe 210b.

[0044] The pressing block 210d-3 has an inclined surface at one end near the insertion ring 205. With the inclined surface, when the insertion ring 205 is inserted into the annular groove on the ring 204, the pressing block 210d-3 can be pressed to make it move smoothly, thereby pressing the opening and closing block 210d-2 to move and open the connecting pipe 210b. This allows lubrication to be turned on after the telescopic sleeve 206 and the insertion ring 205 are installed, and to be turned off when they are removed.

[0045] A second guide block 210d-4 is fixedly connected to the opening / closing block 210d-2 and is slidably connected inside the second groove 210d-1. The second guide block 210d-4 guides and limits the opening / closing block 210d-2. A second spring 210d-5 is fixedly connected to the second guide block 210d-4, and one end of the spring 210d-5 is fixedly connected to the inner wall of the second groove 210d-1. When the opening / closing block 210d-2 opens the connecting pipe 210b, the second guide block 210d-4 compresses it, and the resulting force provides a force for the reset of the second guide block 210d-4 and the opening / closing block 210d-2.

[0046] A third guide block 210d-6 is fixedly connected to the extrusion block 210d-3 and is slidably connected inside the second groove 210d-1. The third guide block 210d-6 guides and limits the extrusion block 210d-3. A third spring 210d-7 is fixedly connected to the third guide block 210d-6, and one end of the spring 210d-7 is fixedly connected to the inner wall of the second groove 210d-1. When the insertion ring 205 is inserted into the annular groove on the ring 204, the extrusion block 210d-3 moves, causing the third guide block 210d-6 to move and compress. The resulting force provides a force for the reset of the third guide block 210d-6 and the extrusion block 210d-3.

[0047] A rotating ring 209 is fitted on the outer surface of the insert ring 205. The rotating ring 209 is fixedly connected to the surface of the insert ring 205, and can be rotated to drive the insert ring 205 to rotate.

[0048] During use, the lubricating oil in the lubricating oil tank 210a wets the cotton column 210c-3 through the connecting pipe 210b, hollow ring 210c-1 and channel 210c-2. During the process of adjusting the height of the conveyor 100 by the extension and retraction of the hydraulic cylinder 201, the output shaft of the hydraulic cylinder 201 moves and drives the ball bearing 210c-4 to rotate, thereby transferring the lubricating oil on the cotton column 210c-3 to the output shaft through the ball bearing 210c-4 for lubrication and protection.

[0049] The telescopic sleeve 206 protects the output shaft of the hydraulic cylinder 201, preventing cement dust from adhering to the output shaft during cement handling. When maintenance is required, rotating the rotating ring 209 causes the insert ring 205 to rotate. Under the action of the rotating groove 207, the locking block 208b gradually disengages from the groove 207 and contacts the outer surface of the insert ring 205, releasing the fixation of the insert ring 205. The insert ring 205 can then be removed from the round block 203 and the round ring 204. The telescopic sleeve 206 can then be compressed for maintenance.

[0050] During this process, under the action of the first spring 208d, the second spring 210d-5 and the third spring 210d-7, the locking block 208b, the opening and closing block 210d-2 and the squeezing block 210d-3 are reset. The opening and closing block 210d-2 moves to seal and close the connecting pipe 210b. The installation is the reverse of the above operation.

[0051] In summary, the combination of the circular block 203, the circular ring 204, the insert ring 205, the telescopic sleeve 206, the slot 207, and the fixing part 208 can protect the output shaft of the hydraulic cylinder 201. Compared with the prior art, it avoids cement dust adhering to its surface and facilitates disassembly and assembly, making it easier for subsequent maintenance. The lubrication mechanism 210 can lubricate and protect the output shaft of the hydraulic cylinder 201. Compared with the prior art, it ensures the integrity of the oil film, reduces motion resistance, and reduces the probability of abnormal noise or jamming caused by long-term use.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
