Description

Technical Field

[0001] This invention relates to the field of hydraulic cylinder technology, and more specifically, to a bearing device for hydraulic cylinders that facilitates dust removal and heat dissipation. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs reciprocating motion (or oscillating motion). When a hydraulic cylinder can achieve reciprocating motion, a speed reduction device can be eliminated, and there is no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. A hydraulic cylinder is basically composed of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffer device, a support base, and an exhaust device.

[0003] The hydraulic cylinder base is a connecting device that connects the hydraulic cylinder and the support. The lifting platform is generally composed of four hydraulic support columns, and each hydraulic support column is generally composed of two hydraulic cylinders. The two hydraulic cylinders are fixed on their respective hydraulic cylinder bases. The support base mainly supports and fixes the hydraulic cylinders, and stabilizes the entire cylinder when the hydraulic cylinder is working, so as to ensure that the hydraulic cylinder stays in a straight line during the movement, and further stabilizes its working effect.

[0004] However, in actual use, it still has some drawbacks. For example, when the existing support base supports the hydraulic cylinder, the cylinder needs to bear a lot of weight during the movement. Therefore, when it comes into contact with the base, the fixing force between the two is relatively weak. Over time, a large gap will grow between the support base and the hydraulic cylinder, which can easily cause the base and the hydraulic cylinder to loosen and fall off, thus affecting the stability of the cylinder and causing it to fail to work properly.

[0005] Therefore, based on the above, the inventor, drawing on years of experience in design, development and manufacturing in the relevant industry, has researched and improved the existing structure and its shortcomings, providing a convenient dust removal and heat dissipation bearing device for hydraulic cylinders, in order to achieve a more practical value. Summary of the Invention

[0006] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a convenient dust removal and heat dissipation support device for hydraulic cylinders. By incorporating a fixing component, a support base, and a fixing port, the fixing side plate is retracted and moved in the opposite direction of the telescopic cylinder by a compression spring. The fixing side plate is then released, allowing it to clamp the side of the telescopic cylinder under the extension and retraction of the compression spring, thus initially fixing it. Simultaneously, one side of the fixing cylinder extends into the fixing port, further ensuring the stability of the fixing side plate during clamping. A locking component is also included; by first grasping the fixing handle, the connecting sleeve plate rotates at the top of the fixing ring. The rotating block, driven by the connecting sleeve plate, rotates around its bottom end inside the fixed sleeve plate via the rotating column. At this time, the fixed slider at the other end of the rotating block slides inside the sliding groove, allowing the wider end of the rotating block to fit against the side of the telescopic cylinder. The three rotating blocks are evenly distributed on the top triangular surface of the fixed sleeve, so that the rotating blocks can evenly apply pressure to the intersection of the triangular sides of the telescopic cylinder, thereby firmly fixing the telescopic cylinder. This further ensures that the telescopic cylinder will not loosen from the support base when moving up and down, thus solving the problem mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bearing device for a hydraulic cylinder that facilitates dust removal and heat dissipation, comprising a bearing base, mounting side plates fixedly connected to the four corners of one side of the bearing base, a telescopic cylinder detachably installed inside the bearing base, a fixing opening on the side of the bearing base, and a threaded groove on one side of the bearing base.

[0008] The support base has a fixed component slidingly mounted inside, the support base has an inner groove, the top of the support base is fixedly installed with a locking component, and the top surface of the mounting side plate has a fixing hole.

[0009] In a preferred embodiment, the fixing component includes a fixing side plate, a fixing cylinder is provided inside the fixing side plate, a threaded inner hole is provided on the inner wall of the fixing cylinder, a fixing limiting post is installed inside the threaded inner hole, and a threaded post is embedded at the other end of the fixing limiting post.

[0010] In a preferred embodiment, a fixing slot is provided on one side of the fixing side plate, and a compression spring is embedded in the fixing slot in a rectangular array inside the fixing slot. An arc-shaped slot is provided on the other side of the fixing side plate.

[0011] In a preferred embodiment, the locking assembly includes a retaining collar, the top surface of which is slidably fitted onto a connecting plate, and a retaining handle is embedded in the side of the connecting plate, the surface of which is provided with an anti-slip stripe structure.

[0012] In a preferred embodiment, mounting base plates are embedded on both the left and right sides of the bottom end of the fixing collar, and fixing screw holes are opened on the surface of the mounting base plates, with locking bolts installed in the internal threads of the fixing screw holes.

[0013] In a preferred embodiment, a support side frame is inlaid on the side of the fixing collar, and an mounting block is inlaid on the top of the support side frame. A fixing side plate is integrally formed on the side of the mounting block.

[0014] In a preferred embodiment, the top of the mounting block is provided with a sliding groove, the side of the rotating block is fitted with a fixed slider, and the other end of the rotating block is fitted with a rotating column.

[0015] In a preferred embodiment, the rotating column is wider at the top and narrower at the bottom, the bottom end of the rotating column slides in contact with the top surface of the fixed collar, the top end of the rotating column inside one side of the rotating block is fitted inside the connecting sleeve plate, the bottom end of the fixed slider is slidably fitted to the inside of the sliding groove, and the diameter of the fixed slider is adapted to the width of the sliding groove.

[0016] In a preferred embodiment, one side of the rotating block is in contact with the side of the telescopic cylinder. The rotating block is made of a highly elastic material. There are three rotating blocks, and the three rotating blocks are evenly distributed on the top triangular surface of the fixed collar in the outer circumference.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. This invention, by setting up a fixing component, a bearing base, and a fixing port, utilizes the cooperation of these components to retract and move the fixing side plate in the opposite direction of the telescopic cylinder through a compression spring, and relax the fixing side plate, so that it clamps the side of the telescopic cylinder under the extension and contraction action of the compression spring, thereby initially fixing it. At the same time, one side of the fixing cylinder extends into the interior of the fixing port, further ensuring the stability of the fixing side plate during clamping.

[0019] 2. This invention incorporates a locking assembly. First, the fixed handle is gripped, causing the connecting sleeve to rotate at the top of the fixed collar. Simultaneously, the rotating block, driven by the connecting sleeve, rotates around its bottom end inside the fixed sleeve via a rotating column. At this time, the other end of the rotating block, a fixed slider, slides inside the sliding groove, allowing the wider end of the rotating block to contact the side of the telescopic cylinder. The three rotating blocks are evenly distributed circumferentially on the top triangular surface of the fixed collar, ensuring uniform pressure on the intersection of the triangular sides of the telescopic cylinder. This securely fixes the telescopic cylinder, preventing it from loosening or shifting from the support base during vertical movement. This ensures the telescopic cylinder remains vertical during operation, thus improving its working accuracy.

[0020] 3. By setting up an installation base plate, locking bolts, and installation blocks, the present invention utilizes the cooperation of these components to keep the rotating block in a limited and fixed position during the rotation of the locking assembly, further improving the connection and fit between the structures and the stable operation of the connecting sleeve plate during rotation. This effectively improves the accuracy of the device in fixing the telescopic cylinder and ensures the service life of the structures. Attached Figure Description

A fixed handle 83 is embedded in the side of the connecting sleeve plate 82. The surface of the fixed handle 83 is provided with an anti-slip stripe structure. The bottom left and right sides of the fixed collar 81 are both fitted with mounting base plates 84. The surface of the mounting base plate 84 is provided with fixing screw holes 85. Locking bolts 86 are installed in the internal threads of the fixing screw holes 85. A support side frame 88 is embedded in the side of the fixed collar 81. A mounting block 87 is embedded in the top of the support side frame 88. A fixed side plate 89 is integrally formed on the side of the mounting block 87.

[0033] The top of the mounting block 87 is provided with a sliding groove 891, the side of the rotating block 892 is inlaid with a fixed slider 893, and the other end of the rotating block 892 is inlaid with a rotating column 894.

[0034] Please refer to the attached instruction manual for details. Figure 3-7 The rotating column 894 is wider at the top and narrower at the bottom. The bottom end of the rotating column 894 slides in contact with the top surface of the fixed collar 81. The top end of the rotating column 894 inside one side of the rotating block 892 is rotated and fitted inside the connecting sleeve plate 82. The bottom end of the fixed slider 893 slides and fits in contact with the inside of the sliding groove 891. The diameter of the fixed slider 893 is compatible with the width of the sliding groove 891.

[0035] The specific implementation method is as follows: the bottom end of the rotating column 894 slides in contact with the top surface of the fixed collar 81, and the top end of the rotating column 894 inside one side of the rotating block 892 rotates and fits inside the connecting sleeve plate 82, so that when the rotating block 892 rotates through the connecting sleeve plate 82, its overall structure can maintain high stability during sliding.

[0036] Please refer to the attached instruction manual for details. Figure 6-7 One side of the rotating block 892 is in contact with the side of the telescopic cylinder 3. The rotating block 892 is made of a highly elastic material.

[0037] The specific implementation method is as follows: the three rotating blocks 892 are evenly distributed on the top triangular surface of the fixed collar 81 in the outer circumference, so that the rotating blocks 892 can evenly apply pressure to the intersection of the side triangles of the telescopic cylinder 3, thereby firmly fixing the telescopic cylinder 3 inside the bearing base 1.

[0038] Working principle of the invention:

[0039] Step 1: First, the operator assembles all the components of the device normally, and then starts the device normally.

[0040] Step 2: First, the operator places the telescopic cylinder 3 inside the bearing base 1. At this time, the fixed side plate 61 is moved in the opposite direction of the telescopic cylinder 3 by the compression spring 67, and the fixed side plate 61 is released, so that it clamps the side of the telescopic cylinder 3 under the extension and retraction action of the compression spring 67, thereby initially fixing it. Then, the fixed handle 83 is grasped, causing the connecting sleeve 82 to rotate at the top of the fixed sleeve 81. At the same time, the rotating block 892, driven by the connecting sleeve 82, rotates around its bottom end inside the fixed sleeve 82 through the rotating column 894. As the rotating block 892 rotates, the other end of the fixed slider 893 slides inside the sliding groove 891, allowing the wider end of the rotating block 892 to come into contact with the side of the telescopic cylinder 3. The three rotating blocks 892 are evenly distributed circumferentially on the top triangular surface of the fixed collar 81, ensuring uniform pressure is applied to the intersection of the triangular sides of the telescopic cylinder 3. This securely fixes the telescopic cylinder 3, further enhancing the device's practicality. Finally, the device completes the fixation of the telescopic cylinder 3.

[0041] Step 3: First, the operator shuts down the device normally. Then, the operator checks whether the fixing between the various components of the device is normal. Then, the operator replaces and repairs the aging and severely worn parts inside the device.

[0042] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
