Description

Technical Field

[0001] This utility model relates to the field of engine hoisting technology, and in particular to an engine hoisting structure. Background Technology

[0002] In many scenarios such as modern industrial production, machinery maintenance, and equipment handling, engine hoisting is a crucial step. As the core power source of various mechanical equipment, engines are usually large in size, heavy in weight, and have a precise structure. This places extremely high demands on the hoisting process, which not only requires ensuring the safety and stability of the hoisting process but also requires avoiding damage to the engine due to improper hoisting operations.

[0003] A search revealed a Chinese patent publication number CN219507443U that discloses a lifting structure for transporting automobile engines. The silicone layer has good moisture resistance and shock resistance, providing protection against moisture, shock, and corrosion. The support plate slides to allow the sponge layer to fit against the automobile engine, protecting the top of the engine. The housing and top cover provide external protection, while the silicone and sponge layers provide internal protection. This facilitates the securing of the automobile engine during lifting, prevents wear on the edges and corners during lifting, and protects the engine from severe impacts, reducing the damage rate during lifting and handling. It is suitable for lifting and handling operations within factory buildings.

[0004] The above-mentioned and existing related technologies often have the following drawbacks: Although the engine can be protected by the housing and top cover, during use, due to the heavy weight of the engine, the housing does not have a clear and reasonable structure for placing the engine. If only the top opening is used, it is difficult to put the engine into the housing when the engine is large or heavy, and it is easy to collide with the edge of the housing, causing damage to the engine. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the engine is too heavy to be placed into the structure during hoisting, which leads to inconvenience in operation. Therefore, we propose an engine hoisting structure.

[0006] To achieve the above objectives, this application adopts the following technical solution: an engine hoisting structure, including a housing, a housing cover at the upper end of the housing, a side plate hinged to one side of the housing, a snap-fit ​​component inside the housing, a clamping component inside the housing, and a pressing component at the lower end of the housing cover. One end of the side plate is provided with an inclined plate, and a first roller is rotatably installed inside the side plate. A second roller is installed inside the housing. The pressing component includes a hydraulic rod installed on the inner wall of the housing cover. A pressing plate is fixed to the output end of the hydraulic rod. The pressing plate corresponds to the second roller. An elastic sponge is fixed to the lower end of the pressing plate. The clamping component includes a support plate installed on the inner wall of the housing. An electric push rod is installed at the lower end of the support plate. A clamping plate is fixed to the output end of the electric push rod. The clamping plate engages with the second roller. An arc-shaped groove is opened on the outer surface of the clamping plate. The size of the arc-shaped groove matches the outer contour of the second roller. The engine is guided into the housing through the side plate, the first roller, and the second roller, making operation convenient.

[0007] Preferably, the upper end of the housing is symmetrically provided with a first lifting ring, and the upper end of the housing cover is symmetrically provided with a second lifting ring. There are four sets of both the first and second lifting rings. The engine is lifted using the first and second lifting rings to ensure the stability of the lifting.

[0008] Preferably, a T-shaped block is fixed on the lower surface of the lid, and a T-shaped groove is provided on the upper surface of the box body. The T-shaped block and the T-shaped groove are engaged, and the box body and the lid are connected by the engagement of the T-shaped block and the T-shaped groove.

[0009] Preferably, one end of the box body is provided with a bolt, which passes through a T-slot and is threaded to the box cover, thereby further enhancing the stability of the connection between the box cover and the box body.

[0010] Preferably, the side of the housing is provided with a groove, and two sets of snap-fit ​​components are provided. The snap-fit ​​components include snap-fit ​​blocks provided inside the grooves. The outer surface of the snap-fit ​​blocks is provided with handles and screws. The side of the side plate is provided with a cavity, and the cavity is provided with screw holes. The screws pass through the snap-fit ​​blocks and are threadedly connected to the screw holes. The side plates are fixed to the housing by using the snap-fit ​​blocks and screws.

[0011] Preferably, the lower end of the box is provided with support legs, and four sets of support legs are provided to avoid the box from directly contacting the ground and causing wear.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, the engine is guided to slide in via an inclined plate, a first roller, a second roller, an electric push rod, an arc-shaped clamping plate, a hydraulic rod, an elastic sponge, and a pressing plate. The inclined plate, combined with the first and second rollers to reduce drag, significantly reduces the engine's movement resistance and improves operational convenience. The electric push rod then drives the arc-shaped clamping plate to press the second roller, preventing slippage and scratches. The hydraulic rod pushes the pressing plate with elastic sponge to press the top of the engine, providing elastic cushioning to avoid squeezing damage. The three components work together to achieve all-around engine fixation. Attached Figure Description

[0014] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0015] Reference Figures 1-3As shown, this utility model provides a technical solution: an engine hoisting structure, including a housing 1 that carries the engine. A cover 2 is detachably connected to the upper end of the housing 1 via bolts. A side plate 3 is hinged to one side of the housing 1 via a hinge. The side plate 3 can rotate freely around the hinge point, facilitating the insertion and removal of the engine. A locking component 4 is provided inside the housing 1, locking the side plate 3. A clamping component 5 is also provided inside the housing 1. A pressing component 6 is provided at the lower end of the cover 2. An inclined plate 31 is integrally formed at the end of the side plate 3 away from the hinge point, forming a 15° inclination angle with the side plate 3. The inclined structure of the side plate 3 guides the engine to slide smoothly into the housing 1, avoiding damage. When the engine is inserted, it collides with the edge of the housing. Several first rollers 32 are rotatably mounted inside the side plate 3 via a pivot. These first rollers 32 are evenly distributed on the bearing surface of the side plate 3, with their tops slightly higher than the bearing surface. As the engine slides on the side plate 3, the first rollers 32 rotate accordingly, converting the sliding friction between the engine and the side plate 3 into rolling friction, significantly reducing the resistance during engine movement. Similarly, several second rollers 13 are rotatably mounted on the bottom surface of the housing 1 via a pivot. The distribution of the second rollers 13 matches that of the first rollers 32, ensuring that after the engine slides from the side plate 3 into the housing 1, it can continue to move smoothly under the action of the second rollers 13. Moved to the designated position, the pressing component 6 includes a hydraulic rod 61, a pressing plate 62, and an elastic sponge 63. The hydraulic rod 61 is fixed to the inner wall of the cover 2 by bolts. The output end of the hydraulic rod 61 is fixedly connected to the pressing plate 62 by bolts. The pressing plate 62 is a rectangular steel plate, and its size is adapted to the bearing surface size inside the housing 1. The lower end of the pressing plate 62 is glued with elastic sponge 63. The elastic sponge 63 has good elasticity and cushioning performance. When the pressing plate 62 presses down on the engine, the elastic sponge 63 can conform to the top surface of the engine, which can effectively fix the engine and avoid excessive pressing pressure that may cause squeezing damage to the engine. The clamping component 5 includes a support. The support plate 51, electric push rod 52, and clamping plate 53 are welded to the upper part of the inner wall on both sides of the housing 1, and the support plate 51 is in a horizontal state. The lower end of the support plate 51 is fixedly installed with electric push rod 52 by bolts. The output end of electric push rod 52 is fixedly connected to clamping plate 53 by flange. The outer surface of clamping plate 53 is provided with arc groove 54. The arc of arc groove 54 matches the outer contour of second roller 13. The inner surface of arc groove 54 is pasted with rubber anti-slip pad. The rubber anti-slip pad can not only increase the friction between clamping plate 53 and second roller 13 and improve clamping stability, but also prevent the surface of clamping plate 53 from directly contacting the surface of second roller 13 and causing scratch damage.

[0016] Reference Figure 2As shown in this embodiment: four sets of first lifting rings 11 are symmetrically arranged on the upper end of the housing 1. The first lifting rings 11 are fixedly connected to the upper end face of the housing 1 by welding, and the four sets of first lifting rings 11 are respectively located at the four corners of the upper end face of the housing 1. The first lifting rings 11 can bear the overall weight of the engine and the housing 1, avoiding the safety accident caused by the lifting rings breaking during the lifting process. Four sets of second lifting rings 21 are symmetrically arranged on the upper end of the housing cover 2. The structure, size and material of the second lifting rings 21 are completely the same as those of the first lifting rings 11, and the four sets of second lifting rings 21 are respectively located at the four corners of the upper end face of the housing cover 2. The second lifting rings 21 are fixedly connected to the upper end face of the housing cover 2 by welding. When the housing cover 2 and the housing 1 are fixed by bolts, the first lifting rings 11 and the second lifting rings 21 form a cooperative load-bearing structure, which can distribute the tension during the lifting process and further improve the lifting safety.

[0017] Reference Figure 3 As shown in this embodiment: a T-slot 16 is provided on the upper surface of the box body 1. There are two T-slots 16, which are located on the two sides of the upper end face of the box body 1 along the length direction. The surface of the groove wall of the T-slot 16 is polished. A T-block 22 is fixed on the lower surface of the box cover 2. The T-block 22 is fixedly connected to the lower surface of the box cover 2 by welding. The number and position of the T-block 22 correspond one-to-one with the T-slots 16 on the box body 1, ensuring that the T-block 22 can be smoothly inserted into the T-slot 16 and there is no obvious looseness after the insertion. When the box cover 2 is closed on the box body 1, the T-block 22 and the T-slot 16 are engaged to form a preliminary positioning and limiting structure.

[0018] A fastening bolt 14 is provided at one end of the housing 1. The fastening bolt 14 passes through the groove wall of the T-slot 16, and the threaded end of the fastening bolt 14 faces the housing cover 2. An internal threaded hole is opened on the lower surface of the housing cover 2 corresponding to the position of the fastening bolt 14. The specification of the internal threaded hole is adapted to the fastening bolt 14 to ensure that the fastening bolt 14 can achieve a stable threaded connection with the housing cover 2. The fastening bolt 14 further enhances the stability of the connection between the housing cover 2 and the housing 1.

[0019] Reference Figure 2As shown in this embodiment: a groove 12 is provided on the side of the housing 1, and a cavity 33 is provided on the side of the side plate 3. The position of the cavity 33 corresponds to the groove 12 on the housing 1. When the side plate 3 is closed, the cavity 33 and the groove 12 form a complete receiving space for accommodating the snap-fit ​​block 42 and the screw 43. A handle 41 is fixed on the outer surface of the snap-fit ​​block 42. The snap-fit ​​block 42 can be easily snapped in by pushing and pulling the handle 41. The cavity 33 has a rectangular structure, and its size is adapted to the extension end of the snap-fit ​​block 42 and the screw 43. A screw hole 34 is provided inside the cavity 33. There are two screw holes 34, which correspond one-to-one with the positions of the two screws 43 on the snap-fit ​​block 42. The specifications of the screw hole 34 are adapted to the screw 43 to ensure that the screw 43 can achieve a stable threaded connection with the screw hole 34 after passing through the snap-fit ​​block 42, thereby fixing the snap-fit ​​block 42, the side plate 3 and the housing 1 into one unit.

[0020] Reference Figure 3 As shown in this embodiment: four sets of support legs 15 are provided at the lower end of the box body 1. The support legs 15 are fixed to the four corners of the lower end face of the box body 1 by welding. Rubber anti-slip pads are pasted on the lower end face of the support legs 15. The rubber anti-slip pads can increase the friction between the support legs 15 and the ground, prevent the box body 1 from sliding when placed, and also play a buffering role to avoid the box body 1 from directly contacting the ground and causing wear.

[0021] Working principle: First, rotate and open the side plate 3 hinged to the housing 1. The inclined plate 31 of the side plate 3 guides the engine to be placed on the first roller 32 of the side plate 3. The first roller 32 rolls to reduce resistance, allowing the engine to slide into the housing 1 along the inclined plate 31. Under the rolling action of the second roller 13 inside the housing 1, it moves smoothly to the designated position. Activate the electric push rod 52 of the clamping component 5 to push the arc-shaped clamping plate 53 to clamp the second roller 13. Close the side plate 3 so that the cavity 33 of the side plate 3 is aligned with the groove 12 of the housing 1. Insert the snap-fit ​​block 42 of the snap-fit ​​component 4 into the groove 12 and the cavity 33, and then connect it with the screw 43. The screw hole 34 is threaded to fix the side plate 3 and initially position the engine; finally, the cover 2 is put on, so that the T-shaped block 22 of the cover 2 is inserted into the T-shaped groove 16 of the box body 1 for initial positioning. Then, the box body 1 and the cover 2 are threaded together with the fastening bolt 14. Finally, the hydraulic rod 61 of the pressing component 6 is activated to push the pressing plate 62 with elastic sponge 63 to press the top of the engine, so as to achieve all-round fixation of the engine. The external hoisting equipment is connected to the four sets of first lifting rings 11 of the box body 1 and the four sets of second lifting rings 21 of the cover 2. The two sets of lifting rings work together to bear the weight and distribute the tension, so as to steadily lift the box body 1 containing the engine and transport it to the designated location.
