Description

Technical Field

[0001] This utility model relates to the field of engine assembly technology, specifically to an engine suspension mounting and adjustment frame. Background Technology

[0002] In engine manufacturing and assembly, although small engines (such as light power units, auxiliary power units, etc.) have smaller power (usually 50-500 horsepower) and lighter weight (mostly 100-500 kg), the reliability of their connection with the main body is still a core element to ensure the safe operation of the equipment. As a key component connecting the engine and the main body, the mounting of small engines needs to accurately transmit thrust, gravity and vibration loads. The spatial position and attitude deviation during installation must be controlled within a reasonable range, otherwise it may cause problems such as increased vibration and structural stress concentration, affecting the operational stability and service life of the equipment.

[0003] Currently, most systems use fixed steel frame structures, which achieve initial engine positioning through pre-set support points and hoisting ropes. This only meets the basic requirement of hoisting the engine from the ground to the installation area and providing temporary support. It lacks a targeted fine-tuning mechanism, making it impossible to flexibly adjust the engine's spatial position. The ease of use of the hoist is also poor. Therefore, we need to propose an engine hoisting and installation adjustment frame. Utility Model Content

[0004] The purpose of this utility model is to provide an engine hoisting and adjustment frame. Through the design of a movable base, an adjustable pitch beam, and an adjustable electric hoist, the flexibility, convenience, and accuracy of the installation process are significantly improved, which can better meet the installation needs of small engine hoists and solve the problems mentioned in the background art.

A hydraulic cylinder is hinged to the second hinge seat, and a third hinge seat is connected to the top end of the telescopic end of the hydraulic cylinder. The third hinge seat is fixedly installed at the bottom of the crossbeam.

[0009] Preferably, the power assembly includes a positioning plate, which is fixedly installed on the top of the crossbeam. The connecting rod is slidably inserted into the interior of the positioning plate. Rotary seats are fixedly connected to both the positioning plate and the top of the crossbeam. Screws are rotatably installed on opposite sides of the two sets of rotating seats. One end of the screw passes through one set of rotating seats and is connected to a reduction motor. A movable block is threaded onto the outer wall of the screw. The bottom of the movable block passes through the positioning plate and is fixedly connected to the top of the connecting rod.

[0010] Preferably, the positioning plate has a guide groove inside that matches the connecting rod, and the connecting rod is slidably inserted into the guide groove.

[0011] Preferably, the top of the positioning plate has a through groove adapted to the movable block, and the movable block is slidably connected inside the through groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, through its movable base, enables the entire device to move flexibly within the installation area, facilitating the transport of the engine hanger to different installation positions. The top of the column is hinged to the crossbeam via a first hinge seat. In conjunction with the actuator on the column, the tilt angle of the crossbeam can be flexibly adjusted. This design allows the engine hanger suspended on the crossbeam to change its tilt angle according to actual installation needs, better adapting to the angle requirements when connecting the engine to the main body. This effectively avoids installation difficulties caused by angle deviations, laying the foundation for subsequent precise docking. One end of the connecting rod at the top of the crossbeam is connected to an electric hoist, and the crossbeam is equipped with a power component for adjusting the position of the electric hoist.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution:

[0023] An engine mounting and adjustment frame includes: a movable base frame 1, with a column 2 fixedly connected to its top. A first hinge seat 3 is fixedly connected to the top of the column 2, and a crossbeam 4 is hinged to the first hinge seat 3. An actuator 5 for adjusting the pitch angle of the column 2 is provided on the column 2. By combining the movable base frame 1, column 2, first hinge seat 3, crossbeam 4, and actuator 5, a stable support foundation and angle adjustment capability are provided for the entire frame, achieving the effect of meeting the position and angle requirements under different installation scenarios. The movable base frame 1 is made of high-strength steel and has wear-resistant rubber wheels installed at the bottom. This not only provides strong load-bearing capacity but also allows for smooth movement in various ground environments. Furthermore, the rubber wheels are equipped with braking devices to fix the position at any time, enhancing operational safety.

[0024] A connecting rod 6 is located at the top of the crossbeam 4, and an electric hoist 7 is fixedly connected to one end of the connecting rod 6. A power assembly 8 for adjusting the position of the electric hoist 7 is installed on the crossbeam 4, and the connecting rod 6 is connected to the movable end of the power assembly 8. By setting up the connecting rod 6, the electric hoist 7, and the power assembly 8, the position of the electric hoist 7 on the crossbeam 4 is moved, achieving the effect of flexibly adjusting the lifting point according to the engine's hanging position. The connecting rod 6 is made of alloy material, possessing high strength and toughness, effectively bearing the weight of the electric hoist 7 and the lifted engine. Furthermore, its surface is treated with anti-corrosion coating, extending its service life.

[0025] The execution component 5 includes a second hinge seat 501, which is fixedly installed on one side wall of the column 2. A hydraulic cylinder 502 is hinged to the second hinge seat 501. A third hinge seat 503 is connected to the top end of the telescopic end of the hydraulic cylinder 502. The third hinge seat 503 is fixedly installed at the bottom of the crossbeam 4. By setting up the second hinge seat 501, the hydraulic cylinder 502, and the third hinge seat 503, the telescopic movement of the hydraulic cylinder 502 drives the crossbeam 4 to rotate around the first hinge seat 3, achieving the effect of precisely adjusting the pitch angle of the crossbeam 4. The hydraulic cylinder 502 is equipped with a high-precision hydraulic control system, which can realize stepless speed regulation, making the adjustment of the pitch angle of the crossbeam 4 more stable and precise, and with a fast response speed, which can quickly meet the adjustment requirements of the installation angle.

[0026] The power assembly 8 includes a positioning plate 801, which is fixedly installed on the top of the crossbeam 4. The connecting rod 6 is slidably inserted into the interior of the positioning plate 801. Rotating seats 802 are fixedly connected to both the positioning plate 801 and the top of the crossbeam 4. Screws 803 are rotatably installed on opposite sides of the two sets of rotating seats 802. One end of the screw 803 passes through one set of rotating seats 802 and is connected to a reduction motor 804. A movable block 805 is threaded onto the outer wall of the screw 803. The bottom of the movable block 805 passes through the positioning plate 801 and is fixedly connected to the top of the connecting rod 6. By setting up the positioning plate 801, rotating seats 802, screws 803, reduction motors 804, and movable blocks 805, the reduction motor 804 drives the screw 803 to rotate, which in turn moves the movable block 805 and the connecting rod 6, achieving the effect of precisely adjusting the position of the electric hoist 7. The screw 803 adopts a high-precision trapezoidal thread design, with a small clearance between it and the movable block 805, resulting in high transmission efficiency. This ensures that the position adjustment accuracy of the electric hoist 7 reaches the millimeter level, meeting the high-precision requirements of engine installation.

[0027] The positioning plate 801 has a guide groove 9 inside that matches the connecting rod 6. The connecting rod 6 is slidably inserted into the guide groove 9. By setting the guide groove 9, the sliding direction of the connecting rod 6 is restricted and guided, thus ensuring smooth movement of the connecting rod 6 and preventing deviation. The inner wall of the guide groove 9 is precision machined and polished, with a low surface roughness, which reduces the frictional resistance when the connecting rod 6 slides, making the movement smoother. It also reduces wear on components and extends the service life of the device.

[0028] The top of the positioning plate 801 has a through groove 10 that matches the movable block 805. The movable block 805 is slidably connected inside the through groove 10. By setting the through groove 10, space and guidance are provided for the movement of the movable block 805, ensuring that the movable block 805 drives the connecting rod 6 to move smoothly. The size of the through groove 10 matches the movable block 805, and the fit between the two is highly precise, which can effectively prevent the movable block 805 from shaking or getting stuck during movement, ensuring the stability of power transmission.

[0029] A geared motor 804 is fixedly mounted on one side wall of one of the rotating seats 802. One end of the output shaft of the geared motor 804 is fixedly connected to one end of the screw 803. By fixing the geared motor 804 and connecting it to the screw 803, the stability and reliability of power transmission are ensured, achieving the effect of stable rotation of the screw 803. The geared motor 804 has an overload protection function. When the load exceeds the rated value, the motor can automatically stop, avoiding damage to the motor and other components due to overload. At the same time, its low operating noise can improve the working environment.

[0030] The electric hoist 7 has a lifting rope 11 at its bottom, with a hook 12 connected to the bottom end of the rope 11. A guide wheel assembly 13 is installed on the crossbeam 4 to keep the hook 12 vertical. By using the lifting rope 11, hook 12, and guide wheel assembly 13, the engine can be lifted, and the guide wheel assembly 13 ensures the hook 12 remains vertical, achieving a stable lifting effect. The lifting rope 11 is made of high-strength steel wire rope, possessing extremely high tensile strength and wear resistance, capable of bearing the weight of the engine and ensuring safety during lifting. Furthermore, the surface of the steel wire rope is coated with an anti-rust layer, allowing it to adapt to different working environments.

[0031] The guide wheel assembly 13 includes two sets of connecting frames 1301. The top ends of the two sets of connecting frames 1301 are fixedly connected to the side walls of the crossbeam 4, respectively. A fixed pulley 1302 is rotatably installed between the two sets of connecting frames 1301, and the lifting rope 11 abuts against the outer wall of the fixed pulley 1302. By setting the connecting frames 1301 and the fixed pulley 1302, the direction of force on the lifting rope 11 is changed and friction is reduced, thus achieving the effect of keeping the hook 12 vertical and ensuring stable lifting. The fixed pulley 1302 uses high-quality bearings, rotates flexibly, has a low coefficient of friction, and can reduce the wear of the lifting rope 11. At the same time, the connecting frames 1301 and the crossbeam 4 are connected by welding, which has high connection strength and can ensure the stability of the fixed pulley 1302 during operation.

[0032] Working principle: First, the movable base 1 is used to move the entire device to the appropriate position required for engine installation. Then, the braking device of the movable base 1 is locked to prevent the device from moving during subsequent operations. Next, the electric hoist 7 is operated to lift the engine suspension via the lifting rope 11 and hook 12. At this time, the fixed pulley 1302 in the guide wheel assembly 13 cooperates with the lifting rope 11 to ensure that the hook 12 is always in a vertical position, preventing the engine suspension from tilting during the lifting process. When it is necessary to adjust the pitch angle of the engine suspension to meet the installation requirements, the hydraulic cylinder 502 in the actuator assembly 5 is activated. The extension or retraction end of the hydraulic cylinder 502 extends or retracts, driving the crossbeam 4 to rotate around the first hinge seat 3, thereby achieving precise adjustment of the pitch angle of the engine suspension. To adjust the position of the electric hoist 7 and move the engine hanger to a suitable horizontal installation position, the geared motor 804 in the power assembly 8 is started. The geared motor 804 drives the screw 803 to rotate between the rotating seats 802. Since the movable block 805 is threadedly connected to the screw 803, the rotation of the screw 803 causes the movable block 805 to move along the through groove 10. The movable block 805 then drives the connecting rod 6 to slide along the guide groove 9, ultimately achieving precise adjustment of the horizontal position of the electric hoist 7. Through the above series of position and angle adjustments, the engine hanger can be accurately docked with the main body, completing the engine installation operation.
