Description

Technical Field

[0001] The utility model belongs to the technical field of maintenance equipment, in particular to a hoisting device for engine maintenance. Background Art

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. Due to the weight of the engine, lifting equipment is required for regular engine maintenance. When the existing engine maintenance lifting equipment is used, moving wheels are installed to make the equipment easy to move. In order to ensure the stability of the equipment during use, adjustment components are installed to increase the contact area between the equipment and the ground, thereby ensuring the stability of the device during use. Although the stability of the equipment is guaranteed, it is necessary to manually find the hanging point of the engine during lifting, and use the hook of the lifting equipment in conjunction with the hanging point. The lifting process requires manual assistance, which makes the lifting operation time-consuming and labor-intensive.

[0003] After searching, the Chinese patent document (authorization announcement number CN215925970U) shows a kind of lifting equipment for engine maintenance, and its technical scheme includes: two groups of adjustable base frames, the tops of the two groups of adjustable base frames are respectively provided with a first cross bar and a second cross bar, one end of the second cross bar is rotatably provided with a first knob, and one side of the first knob is provided with a first screw. By providing an adjustable base frame, the utility model can expand the contact area between the bottom and the ground, effectively preventing the equipment from sinking and tipping over during use, and through the coordination between different structures, the device is convenient for adjusting the distance between the two groups of hooks according to engines of different sizes. Although this patent ensures the stability of the equipment, it is necessary to manually find the suspension point of the engine during lifting, and the lifting process requires manual assistance when using the hook of the lifting equipment in conjunction with the suspension point, which makes the lifting operation more time-consuming and labor-intensive.

[0012] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0013] The engine maintenance hoisting equipment benefits from the design of the winch, stabilizing component and limiting component. When hoisting the engine, the winch is started to drive the rope to be reeled in, thereby driving the support column at the bottom of the lifting ring to rise. The rise of the support column drives the sliders at the bottom of the two movable rods to move toward each other. The toward-together movement of the sliders drives the two fixing plates at the bottom to move toward each other, thereby realizing automatic fixation of the engine, making the hoisting operation more time-saving and labor-saving. The designed stabilizing component can ensure the stability of the device when in use, and the designed limiting component can limit the engine during the hoisting process to prevent the engine from having to be replaced during hoisting, thereby ensuring the safety of the hoisting process.

[0014] The engine maintenance hoisting equipment can automatically fix the engine, making the hoisting operation more time-saving and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., which shall be based on actual needs. The technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail. However, where appropriate, the technologies, methods and equipment should be regarded as part of the specification, and the proportions of the devices in the drawings are for reference only and may be adjusted to a certain extent according to actual usage.

[0026] Examples, such as Figures 1 to 5 As shown, the bottom end of the base 1 is an open design, and a protective shell 5 is installed on the top of the mounting frame 2. The design of the protective shell 5 can protect the winch 6 and reduce certain noise during operation. A winch 6 for hoisting the engine is installed on the inner side of the protective shell 5. A hook at one end of the winch 6 is connected with a lifting ring 9. The lifting ring 9 and the hook are detachably connected. A rectangular installation box 7 is provided at the bottom end of the lifting ring 9. A sliding rod 13 for auxiliary adjustment is installed on the inner side of the installation box 7. The outer periphery of the sliding rod 13 is slidably connected to two supporting sliders 14. The bottom end of the slider 14 is penetrated and connected with a fixed fixing member for fixing the engine. The fixing plate 10 is L-shaped and can lift the engine. When the engine is fixed, the engine needs to be placed on the load-bearing plate so that a certain distance is left between the engine and the ground, so that the fixing plate 10 can be embedded from both sides. A positioning box 11 is welded on the side of the fixing plate 10 located outside the installation box 7. The top of the slider 14 is connected to a movable rod 12 through a hinge. The end of the movable rod 12 away from the slider 14 is hingedly connected to a support column 8. The top of the support column 8 passes through a limiting groove provided at the top of the installation box 7 and is connected and fixed to a lifting ring 9. The movable rod 12 is slidably connected to the limiting groove during adjustment and a certain limiting effect is activated.

[0027] The stabilizing assembly 3 includes a moving wheel 31 installed at the bottom end of the base 1 and a first screw rod 33 installed on the inner side of the base 1. The first screw rod 33 is a two-stage design that can meet the requirements of the two linkage blocks 35 moving toward each other. One end of the first screw rod 33 passes through the base 1 and is connected to an adjustment knob 32. The rotation direction of the adjustment knob 32 is determined according to the actual situation. The adjustment knob 32 and the side of the base 1 are provided with a plurality of positioning holes, which are implemented with the insertion rod after the adjustment is completed to ensure the stability of the adjustment knob 32. The outer periphery of the first screw rod 33 is threadedly connected to two linkage blocks 35 connected to the inner wall of the base 1, and the bottom end of the linkage block 35 is connected to a linkage rod 34 through a hinge. The end of the linkage rod 34 away from the linkage block 35 is hingedly connected to the base, and the bottom end of the base is connected to a support plate 36 with an anti-skid pad. The design of the anti-skid pad can increase the friction between the base and the ground.

[0028] The limit assembly 4 includes a limit box 43 installed on both sides of the mounting frame 2, a guide rod 49 installed inside the limit box 43, and a limit frame 41 installed on the outer periphery of the guide rod 49. The limit frame 41 is of U-shaped design. A reset spring 48 is installed between the side of the limit frame 41 and the inner wall of the limit box 43. The reset spring 48 can drive the limit frame 41 to reset. A second screw rod 44 is installed inside the limit frame 41. A drive motor that provides adjustment power for the second screw rod 44 is installed on the side of the limit frame 41. 42, the driving motor 42 cooperates with the second screw rod 44 to adjust the distance between the two adjusting blocks 45, and the second screw rod 44 is also a two-stage design. The outer peripheral thread of the second screw rod 44 is connected to two adjusting blocks 45 connected to the limit frame 41, and an electric push rod 46 is installed on the top of the adjusting block 45, and the driving end of the electric push rod 46 is connected to a positioning block 47. The positioning block 47 is used in conjunction with the positioning box 11 to ensure that there is no shaking during hoisting, and the positioning box 11 is designed with openings at both ends.

[0029] The driving motor 42, winch 6 and electric push rod 46 are all conventional instruments. The working principle, size and model are irrelevant to the function of the present application, so they are not described in detail. They are all controlled by a remote control switch. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices. Therefore, the present invention will no longer explain the control method and circuit connection in detail, and the proportions of the drawings are for reference only and can be adjusted to a certain extent according to actual usage.

[0030] How it works

[0031] When the engine overhaul hoisting equipment is used, the engine to be hoisted and overhauled is placed on the bearing plate, so that a certain gap is left at both ends to ensure the embedding of the fixed plate 10, the base 1 is moved to the specified position, and the two adjusting knobs 32 are turned to drive the two first screw rods 33 to adjust. The adjustment of the first screw rod 33 can drive the two linkage blocks 35 to move toward each other. The adjustment of the linkage block 35 drives the linkage rod 34 at the bottom end to adjust the position, so that the support plate 36 contacts the ground. After the adjustment is completed, the winch 6 is started to drive the winding rope to be wound, thereby driving the support column 8 at the bottom end of the lifting ring 9 to rise. The rise of the support column 8 drives the sliders 14 at the bottom ends of the two movable rods 12 to move toward each other. The movement of the sliders 14 toward each other drives the two fixed plates 10 at the bottom to move toward each other, thereby realizing automatic fixation of the engine, starting the drive motor 42 to drive the second screw rod 44 to rotate, thereby adjusting the spacing between the two adjustment blocks 45, starting the electric push rod 46 to drive the positioning block 47 to be embedded in the positioning box 11, and the fixed engine is limited for hoisting.
