Description

Technical Field

[0001] This utility model relates to the field of repair auxiliary device technology, and in particular to an auxiliary device for repairing the outer surface of a hydraulic cylinder piston in mining engineering. Background Technology

[0002] Mining face equipment is typically equipped with large-diameter mining hydraulic cylinders. These cylinders often face harsh conditions in the mining environment, such as humidity, high sulfur content, high salinity, and dust. Prolonged exposure to such conditions can cause corrosion, impacts, scratches, and other defects on the outer surface of the cylinder's piston, leading to leaks and a series of safety hazards.

[0003] Currently, the traditional method for repairing the outer surface of hydraulic cylinder pistons mainly employs cladding additive manufacturing technology to enhance wear resistance and durability. The cladding process demands extremely high precision: the cladding layer must achieve a good metallurgical bond with the substrate layer, ensuring a uniform and dense surface structure. After machining, the cladding surface must be free from defects such as scorching, cracks, incomplete fusion, dense pitting, porosity, slag inclusions, or loose particles. Furthermore, there must be no undercut at the transition between the cladding and non-cladding areas. The inspection and repair of the cladding layer are particularly crucial during subsequent batch machining. Workpieces with various defects discovered during machining after the cladding process should be classified and processed accordingly. Workpieces requiring repair must undergo further treatment using specialized repair auxiliary equipment.

[0004] However, traditional repair methods typically require workers to rely on specialized lathe equipment to assist in clamping and fixing the hydraulic cylinder piston. Because the hydraulic cylinder piston is relatively large, this clamping and fixing process is not only time-consuming and labor-intensive, but also physically demanding. Furthermore, this repair auxiliary device also incurs high equipment maintenance costs. Utility Model Content

Detailed Implementation

[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] Please see Figures 1-6This utility model provides an auxiliary device for repairing the outer surface of a hydraulic cylinder piston in mining engineering, including a workbench base 1 and two sets of lifting bases 3. The workbench base 1 has four movable wheels 2 installed at its lower surface corners. The two sets of lifting bases 3 are located at the front and rear of the upper surface of the workbench base 1, respectively. The front lifting base 3 is slidably connected to the workbench base 1, while the rear lifting base 3 is fixedly connected to the workbench base 1. A main lifting frame 4 is slidably connected to the right side of the upper surface of both sets of lifting bases 3. The upper end of the main lifting frame 4 is rotatably connected to a main lifting wheel 42 via a main shaft 41. The left side of the upper surface of both sets of lifting bases 3 is fixedly connected to... There is a secondary lifting frame 5, and a secondary shaft 51 is rotatably connected to the upper end of the secondary lifting frame 5. A secondary lifting wheel 52 is fixedly sleeved on the outer side of the secondary shaft 51. A drive component 6 for driving the main lifting frame 4 to move closer to or away from the secondary lifting frame 5 is fixedly connected to the right side of the lifting base 3. A rotary adjustment mechanism 7 for driving the secondary lifting wheel 52 to rotate is connected to one side of the secondary lifting frame 5. A drive component 8 for driving the front lifting base 3 to move closer to or away from the rear lifting base 3 is connected to the worktable base 1. A two-bar linkage 9 is connected to the front side of the rear lifting base 3. A lighting mechanism 10 is connected to the end of the two-bar linkage 9 away from the lifting base 3.

[0028] This utility model provides a repair auxiliary device consisting of an external support and a rotatable structure, which can support and repair the hydraulic cylinder piston, effectively improving the working efficiency of the hydraulic cylinder piston during the repair process, reducing the labor intensity of personnel, and keeping the equipment maintenance cost low.

[0029] Specifically, during use, the main lifting frame 4 can be driven closer to or further away from the auxiliary lifting frame 5 by the first driving component 6, thereby indirectly adjusting the distance between the main lifting wheel 42 and the auxiliary lifting wheel 52 to suit the needs of workpieces of different diameters. The front lifting base 3 can be driven closer to or further away from the rear lifting base 3 by the second driving component 8, thereby adjusting the distance between the two sets of lifting bases 3 to meet the needs of workpieces of different lengths. The auxiliary lifting wheel 52 can be driven to rotate by the rotation adjustment mechanism 7, thereby enabling flexible rotation of the workpiece.

[0030] Specifically, through the two-bar linkage 9 and the lighting mechanism 10, the light can be shone on any point on the workpiece, and when hoisting the workpiece, the lighting mechanism 10 can be rotated to a position away from the worktable base 1 to avoid affecting the normal hoisting of the workpiece.

[0031] Preferably, both the main lifting wheel 42 and the auxiliary lifting wheel 52 can be made of rubber.

[0032] Furthermore, a fixing plate 31 is fixedly connected to the right side of the lifting base 3, and the driving component 6 adopts a hydraulic cylinder, which is fixedly connected to the fixing plate 31. A side plate 43 is fixedly connected to the right side of the main lifting frame 4, and the side plate 43 is fixedly connected to the telescopic end of the hydraulic cylinder.

[0033] Specifically, if it is necessary to adjust the distance between the main lifting wheel 42 and the auxiliary lifting wheel 52, simply control the extension or retraction of the hydraulic cylinder to move the main lifting frame 4 closer to or further away from the auxiliary lifting frame 5, thereby changing the distance between the main lifting wheel 42 and the auxiliary lifting wheel 52.

[0034] Furthermore, the rotary adjustment mechanism 7 includes a fixed base 71, a first bevel gear 72, a second bevel gear 73, and an adjustment rod 74. The fixed base 71 is fixedly connected to one side of the auxiliary support frame 5. One end of the auxiliary shaft 51 rotatably passes through the auxiliary support frame 5 and the fixed base 71 and extends into the interior of the fixed base 71. The first bevel gear 72 is fixedly sleeved on the end of the auxiliary shaft 51 that extends into the interior of the fixed base 71. The second bevel gear 73 meshes with the left side of the first bevel gear 72. The adjustment rod 74 is fixedly connected to the center of the second bevel gear 73. The end of the adjustment rod 74 away from the second bevel gear 73 rotatably passes through the left side of the fixed base 71 and extends into the exterior of the fixed base 71. A handwheel 75 is fixedly sleeved on the end of the adjustment rod 74 that extends into the exterior of the fixed base 71.

[0035] Specifically, when it is necessary to rotate the workpiece, the handwheel 75 can be turned manually. The handwheel 75 drives the second bevel gear 73 to rotate via the adjusting rod 74, which in turn drives the first bevel gear 72 meshing with it to rotate. The first bevel gear 72 drives the auxiliary lifting wheel 52 to rotate via the auxiliary shaft 51, and the auxiliary lifting wheel 52 drives the workpiece to rotate. Preferably, the handwheel 75 can also be replaced by a variable frequency reduction motor to achieve constant speed automatic rotation of the workpiece.

[0036] Furthermore, the workbench base 1 includes two sets of side seats 11 arranged in parallel front and rear and two sets of support columns 12 arranged in parallel left and right. The two sets of support columns 12 are fixedly connected between the two sets of side seats 11. An ear seat 111 is fixedly connected to the center of the upper surface of the side seat 11 located in front. A sleeve 32 is fixedly connected to the middle position of the lifting base 3 located in front. The driving component 8 includes a reduction motor 81 and a lead screw 82. The reduction motor 81 is fixedly connected to the front side of the ear seat 111. The output shaft of the reduction motor 81 rotates through the ear seat 111 and is fixedly connected to the lead screw 82. The end of the lead screw 82 away from the reduction motor 81 is rotatably connected to the lifting base 3 located in the rear. The sleeve 32 is threaded on the outside of the lead screw 82.

[0037] Specifically, when it is necessary to adjust the relative position between the two sets of lifting bases 3, this can be achieved by controlling the operation of the reduction motor 81. The output shaft of the reduction motor 81 will drive the lead screw 82 to rotate. At this time, the sleeve 32 will drive the front lifting base 3 to move linearly along the lead screw 82, thereby causing the front lifting base 3 to gradually move away from or closer to the rear lifting base 3.

[0038] Furthermore, the upper surfaces of both sets of support columns 12 are provided with sliding grooves 121, and the lower surfaces of the front lifting base 3 are fixedly connected with pulley groups 33 on both sides. The two sets of pulley groups 33 are slidably connected to the sliding grooves 121 on the corresponding side.

[0039] Specifically, when the front support base 3 moves, it will drive the pulley group 33 to slide in the slide groove 121, thereby ensuring that the movement of the support base 3 is smoother.

[0040] Furthermore, the two-bar linkage 9 includes a main bar 91 and a secondary bar 92. The main bar 91 is hinged to the front side of the lifting base 3 located at the rear, and the secondary bar 92 is hinged to the end of the main bar 91 away from the lifting base 3.

[0041] Specifically, in actual use, the angle between the main rod 91 and the auxiliary rod 92 can be adjusted according to the needs, thereby changing the position of the lighting mechanism 10 to adapt to different lighting requirements.

[0042] Furthermore, the lighting mechanism 10 includes a support rod 101, a flexible tube 102, and a lighting lamp 103. The support rod 101 is vertically installed at the end of the auxiliary rod 92 away from the main rod 91. The flexible tube 102 is rotatably connected to the upper end of the support rod 101, and the lighting lamp 103 is fixedly connected to the upper end of the flexible tube 102.

[0043] Specifically, the design of the flexible tube 102 allows the lighting lamp 103 to be adjusted to any angle, thereby meeting different lighting needs.

[0044] Furthermore, the lower end of the support rod 101 is threadedly connected to the auxiliary rod 92, the upper end of the support rod 101 is fixedly connected to the base sleeve 1011, and the lower end of the flexible tube 102 is fixedly connected to the rotating ball head 1021, which is rotatably connected inside the base sleeve 1011.

[0045] Specifically, the rotating ball head 1021 below the flexible tube 102 enables the flexible tube 102 to rotate freely 360 degrees relative to the base sleeve 1011.

[0046] It should be noted that: 1. All electrical equipment mentioned in this article is electrically connected to the control terminal, and operators can control the start, stop, and operating status of these electrical devices through the control terminal. 2. This repair auxiliary device can also be applied to welding and chrome plating repair of large metal rods and columns.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
