Technical Field
[0001] This utility model belongs to the field of lifting tool technology, and in particular relates to an engine flywheel lifting tool. Background Technology
[0002] Lifting tools refer to the devices used in lifting machinery to lift heavy objects. Common lifting tools include hooks, slings, shackles, lifting suction cups, clamps, and forks. These lifting tools are widely used in the lifting and hoisting industry, especially in construction sites and logistics transportation. Lifting tools are also needed when moving engine flywheels.
[0003] Most existing engine flywheel lifting devices directly clamp and position the outer ring of the engine flywheel using jaws or clamps, without installing anti-fall components at the bottom of the engine flywheel. This makes the engine flywheel prone to falling due to the loosening of the jaws during lifting, posing a significant safety hazard. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides an engine flywheel lifting device that solves the problem that the engine flywheel is prone to falling during lifting due to the loosening of the claws because no anti-fall component is installed at the bottom of the engine flywheel.
[0005] This utility model is implemented as follows: an engine flywheel hoist includes a mounting plate and a mounting frame fixed on the mounting plate and connected to a hoisting device. Multiple sets of fixed slide rails are evenly fixed to the surface of the mounting plate. A clamping frame for clamping and fixing the flywheel is slidably arranged within each set of fixed slide rails. A cylinder is fixed on the mounting plate, and a top block is fixed to the piston rod of the cylinder. A push plate with one end rotatably mounted on the top inner side of the top of each set of clamping frames is rotatably mounted on the top block. An anti-fall component is provided at the bottom of the mounting plate.
[0006] As a preferred embodiment of this utility model, the anti-fall component includes a hollow square column disposed at the bottom of the mounting plate. A T-shaped movable column is slidably disposed inside the hollow square column. A first spring is fixed to the top of the inner cavity of the hollow square column, and the bottom end of the first spring is fixed to one end of the T-shaped movable column. The other end of the T-shaped movable column extends through to the bottom of the hollow square column and has a snap-fit groove. A cross-shaped base frame for use with a flywheel is inserted into the snap-fit groove. A clamp plate with one end fixed to the cross-shaped base frame is attached to both sides of the T-shaped movable column. An L-shaped insert plate is inserted into the clamp plate and is attached to the back of the T-shaped movable column. One end of the front of the L-shaped insert plate is slidably disposed on the cross-shaped base frame. Multiple sets of second springs are symmetrically fixed along the front-back direction on the side of one set of clamp plates away from the T-shaped movable column, and one end of the second spring is fixed to the L-shaped insert plate. A lifting frame is fixed to the front of the cross-shaped base frame. A pull plate is slidably disposed on the front of one side of the lifting frame. An auxiliary rope is fixed to the back of the pull plate, and one end of the auxiliary rope extends through the cross-shaped base frame and is fixed to the L-shaped insert plate.
[0007] As a preferred embodiment of this utility model, an L-shaped pipe is fixed on the front of the right side of the cross base frame, and a U-shaped pipe is inserted into the right end of the cross base frame, with the auxiliary rope passing through the L-shaped pipe and the U-shaped pipe.
[0008] As a preferred embodiment of this utility model, a first slide rail is provided on the right side of the back of the cross base frame, and one end of the L-shaped insert plate is slidably disposed in the first slide rail; a second slide rail is provided on the front side of one side of the lifting frame, and one end of the pull plate is slidably disposed in the second slide rail.
[0009] As a preferred embodiment of this utility model, each set of clamping frames is symmetrically provided with multiple sets of balls at the bottom end, and the number of balls at the bottom end of each set of clamping frames is at least two.
[0010] As a preferred embodiment of this utility model, a screw is fixed on the hollow square column, and a threaded hole for cooperating with the screw is opened at the bottom end of the mounting plate.
[0011] As a preferred embodiment of this invention, a blocking plate is fixed to the outer side of the top of each set of fixed slide rails for use with a clamping frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention, by incorporating an anti-fall component, utilizes the elastic rebound of a first spring to continuously provide a downward thrust to the T-shaped moving column. This allows the engine flywheel to move upwards a certain distance under the clamping of the gripper and the lifting action of the lifting device. Afterwards, the bottom locking slot of the T-shaped moving column can quickly move downwards to below the engine flywheel, enabling the cross-shaped base frame to be quickly inserted into the locking slot. Combined with the adjustable locking assembly formed by the clamping plate, L-shaped insert plate, second spring, auxiliary rope, and pull plate, the cross-shaped base frame can be quickly positioned at the bottom of the T-shaped moving column. At this point, the cross-shaped base frame with its adjustable self-locking structure effectively supports and positions the bottom of the engine flywheel, effectively preventing it from falling due to the gripper loosening its claws during lifting. This improves the overall anti-fall effect of the lifting device and enhances safety. Attached Figure Description

[0020] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] like Figures 1 to 4As shown in the figure, an engine flywheel lifting device provided by this utility model includes a mounting plate 1 and a mounting frame 2 fixed on the mounting plate 1 and connected to the lifting equipment. A controller is provided on the mounting plate 1. Multiple sets of fixed slide rails 4 are evenly fixed on the surface of the mounting plate 1. A clamping frame 5 for clamping and fixing the flywheel is slidably arranged in each set of fixed slide rails 4. A cylinder 3 is fixed on the mounting plate 1. A top block is fixed to the piston rod of the cylinder 3. A push plate 6 with one end rotatably mounted on the top inner side of each set of clamping frames 5 is provided. An anti-fall component is provided at the bottom of the mounting plate 1. By setting the anti-fall component, the bottom of the engine flywheel can be effectively supported and positioned by using the cross base frame 13 with an adjustable self-locking structure. This can effectively prevent the engine flywheel from falling due to the loosening of the clamping frame 5 during the lifting process, improve the overall anti-fall effect of the lifting device, and improve safety.
[0023] As a preferred embodiment of this invention, the anti-fall component includes a hollow square column 8 disposed at the bottom of the mounting plate 1. A T-shaped movable column 10 is slidably disposed within the hollow square column 8. A first spring 11 is fixed to the top of the inner cavity of the hollow square column 8, and the bottom end of the first spring 11 is fixed to one end of the T-shaped movable column 10. The other end of the T-shaped movable column 10 extends to the bottom of the hollow square column 8 and has a snap-fit groove 12. A cross-shaped base frame 13 for use with a flywheel is inserted into the snap-fit groove 12. Both sides of the T-shaped movable column 10 are fitted with a clamping plate 14, one end of which is fixed to the cross-shaped base frame 13. An L-shaped insert plate 15 is inserted into the clamping plate 14, which is fitted to the back of the T-shaped movable column 10, and one end of the front of the L-shaped insert plate 15 is slidably disposed on the cross-shaped base frame 13. A set of clamping plates 14 is symmetrically fixed with multiple sets of second springs 16 along the front-rear direction on the side away from the T-shaped moving column 10, and one end of the second spring 16 is fixed to the L-shaped insert plate 15. A lifting frame 17 is fixed to the front of the cross base frame 13. A pull plate 21 is slidably arranged on the front of one side of the lifting frame 17. An auxiliary rope 18 is fixed to the back of the pull plate 21, and one end of the auxiliary rope 18 passes through the cross base frame 13 and is fixed to the L-shaped insert plate 15. The design of the clamping plates 14, L-shaped insert plates 15, second springs 16, auxiliary ropes 18 and pull plates 21 can quickly form an adjustable locking assembly for the cross base frame 13, which facilitates the quick positioning of the cross base frame 13 at the bottom of the T-shaped moving column 10 and effectively supports and positions the bottom of the engine flywheel.
[0024] As a preferred embodiment of this utility model, an L-shaped pipe 19 is fixed on the front of the right side of the cross base 13, and a U-shaped pipe 20 is inserted into the right end of the cross base 13. An auxiliary rope 18 passes through the L-shaped pipe 19 and the U-shaped pipe 20. The design of the L-shaped pipe 19 and the U-shaped pipe 20 can guide the auxiliary rope 18, effectively avoid excessive wear at the contact point between the auxiliary rope 18 and the cross base 13, and extend the service life of the auxiliary rope 18.
[0025] As a preferred embodiment of this utility model, a first slide rail 22 is provided on the right side of the back of the cross base frame 13, and one end of the L-shaped insert plate 15 is slidably disposed in the first slide rail 22. A second slide rail 23 is provided on the front side of one side of the lifting frame 17, and one end of the pull plate 21 is slidably disposed in the second slide rail 23. The design of the first slide rail 22 and the second slide rail 23 can effectively limit the sliding of the L-shaped insert plate 15 and the pull plate 21, improve the stability of the L-shaped insert plate 15 and the pull plate 21 when moving, and prevent them from detaching from the cross base frame 13 and the lifting frame 17.
[0026] As a preferred embodiment of this utility model, each set of clamping frames 5 is symmetrically provided with multiple sets of balls 7 at its bottom end, and the number of balls 7 at the bottom end of each set of clamping frames 5 is at least two. The design of the balls 7 can assist in the movement of the bottom end of the clamping frame 5 when it comes into contact with the engine flywheel placement surface, so as to avoid hindering the normal movement of the clamping frame 5.
[0027] As a preferred embodiment of this utility model, a screw 9 is fixed on the hollow square column 8, and a threaded hole for use with the screw 9 is opened at the bottom end of the mounting plate 1. The design of the screw 9 and the threaded hole allows for quick assembly of the hollow square column 8 and facilitates subsequent disassembly, so as to select a suitable hollow square column 8 according to the size of the internal hole diameter of the flywheel.
[0028] As a preferred embodiment of this utility model, each set of fixed slide rails 4 has a baffle plate fixed on the outer side of the top, which is used in conjunction with the clamping frame 5. The design of the baffle plate can limit the clamping frame 5 and effectively prevent the clamping frame 5 from detaching from the fixed slide rail 4.
[0029] The working principle of this utility model:
[0030] refer to Figures 1 to 4The user pre-activates cylinder 3 via the controller, which moves push plate 6, causing clamping frame 5 to move inward synchronously and clamp the side of the engine flywheel at multiple points. At this time, T-shaped moving column 10 contacts the placement surface through the central hole of the engine flywheel, causing it to retract into the hollow square column 8 and compress the first spring 11. After the engine flywheel moves upward a certain distance under the lifting action of the hoisting device connected to the mounting frame 2, T-shaped moving column 10 quickly moves downward under the elastic action of the first spring 11 until its bottom locking groove 12 quickly moves below the engine flywheel. At this time, the user pulls the pull plate 21 in front, which moves the auxiliary rope 18, thereby pulling the L-shaped insert. The plate 15 moves synchronously and stretches the second spring 16 until one end of the L-shaped insert plate 15 moves to the inside of one of the clamping plates 14. At this time, the user uses the lifting frame 17 to insert the cross base frame 13 into the locking groove 12. The user then releases the pull plate 21, and the elastic rebound of the second spring 16 drives the L-shaped insert plate 15 to reset and insert it into the two clamping plates 14, limiting the cross base frame 13 and quickly positioning it at the bottom of the T-shaped moving column 10. At this time, the cross base frame 13 with an adjustable self-locking structure can effectively support and position the bottom of the engine flywheel, effectively preventing the engine flywheel from falling due to the loosening of the clamping frame 5 during lifting, improving the overall anti-fall effect of the lifting device and enhancing safety.
