DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1-5 The utility model provides an embodiment: an I-beam lifting device, including a cylinder body 1, a base 2 and a grabbing mechanism 6, a base 2 is provided at the bottom of the cylinder body 1, a control panel 3 is provided on the outside of the base 2, a hydraulic lifting device 4 is provided above the cylinder body 1, a lifting mechanism 5 is connected to the top of the hydraulic lifting device 4, and a grabbing mechanism 6 is installed at one end of the lifting mechanism 5 away from the hydraulic lifting device 4.

[0022] A control panel 3 is provided on the outside of the base 2. The cylinder body 1 and the base 2 are fixedly connected by welding. Elevated fixing plates 201 are provided around the base 2. The elevated fixing plates provided around the base 2 can be connected to surrounding fixed objects, thereby increasing the supporting area of ​​the device and improving the overall stability. The welded fixed connection between the cylinder body 1 and the base 2 also ensures that the device will not loosen or shift during use, thereby enhancing the stability of the operation.

[0023] The hydraulic lifting device 4 includes a hydraulic lifting rod 401, a load-bearing rod 402 and a cylinder body 1. The cylinder body 1 is rotatably connected to the base 2. A driver is provided in the base 2, which is not shown in the figure. The cylinder body 1 and the hydraulic lifting rod 401 are slidably connected, and the hydraulic lifting rod 401 and the load-bearing rod 402 are fixedly connected, so that the hydraulic lifting device 4 can remain stable during the lifting process while increasing the movement speed.

[0024] The lifting mechanism 5 includes an outer connecting shaft 501, an inner connecting shaft 502, a rotating shaft 503, a main boom 504, an inclined rod 505, a hydraulic rod 506, a front boom 507 and a support rod 508. The outer connecting shaft 501 is fixed to the top of the load-bearing rod 402, the inner side of the outer connecting shaft 501 is connected to the inner connecting shaft 502, the outer end of the inner connecting shaft 502 is sleeved with the rotating shaft 503, the front end of the rotating shaft 503 is connected and installed with the main boom 504, the inclined rod 505 is installed at the upper rear of the main boom 504, the bottom side of the main boom 504 is connected with the hydraulic rod 506, the front bottom of the main boom 504 is connected with the front boom 507, and the inner side of the front boom 507 is installed with the support rod 508, forming a stable rotating connection, thereby ensuring the stability and reliability of the lifting mechanism 5 during operation.

[0025] The connecting outer shaft 501 forms a rotational connection with the rotating shaft 503 through the connecting inner shaft 502. The inclined rod 505 and the hydraulic rod 506 are connected to the main boom 504 and the rotating shaft 503 on the upper and lower sides and move accordingly. The main boom 504 is connected to the grabbing mechanism 6 through the support rod 508. The support rod 508 is connected to the main boom 504, which can effectively and smoothly transfer the weight of the hoisted items to the grabbing mechanism 6 without shaking at will, thereby increasing the gravity and ensuring safety and stability during the lifting of heavy construction materials.

[0026] The grabbing mechanism 6 includes a connecting frame 601, a spring coil 602, a collar 603, a collar fixing rod 604, a lifting handle 605, a lifting rod 606, a rotating rod 607 and a fixed grip 608. The free end of the lifting mechanism 5 is connected to the connecting frame 601. The connecting frame 601 is composed of a frame and a supporting column. The supporting column and the spring coil 602 are rotatably connected. The other end of the spring coil 602 is connected to the collar 603. Before use, the spring coil 602 is manually rotated to compress the state to generate pressure, increase resistance and will not change direction at will. The collar 603 is a ring with a notch. The collar 603 and the collar fixing rod 604 form a closed hook. The bottom of the collar 603 has a bent depression connected to the lifting handle 605. The bottom of the collar 603 is suitable for the size of the lifting handle 605. The two ends of the lifting handle 605 are connected with a lifting rod 606, and the lifting rod is connected to the fixed grab 608 through a rotating rod 607. The fixed grab 608 is in the shape of an existing hook. The grabbing mechanism 6 can flexibly adjust the degree of opening and closing as needed to adapt to objects of different sizes and shapes. The components of the grabbing part can be replaced at will according to the size of the I-beam. The setting of three sets of rotating rods 607 and fixed grab 608 can provide more grabbing points, enhance the fixing force of the I-beam, and ensure that the I-beam will not loosen or slide during lifting and transportation, thereby improving safety and realizing movement in multiple directions. This multi-directional movement design can flexibly adapt to the needs of various lifting tasks. The ring 603 and the ring fixing rod 604 can facilitate the maintenance of the grabbing part after use.

[0027] The spring coil 602 and the collar 603 are welded together, and the collar 603 is opened and closed by the collar fixing rod 604. There are at least three groups of rotating rods 607 and fixed grabs 608, which must be two groups and the middle group in the opposite direction, so that a more balanced force distribution can be achieved during the lifting process. When the I-beam is grabbed and lifted, the forces between each group of rotating rods 607 and fixed grabs 608 will be balanced with each other, reducing the impact of back and forth deviation after lifting and improving stability.

[0028] Working principle: First, the operator places the cylinder body 1 at the position where the lifting operation is required, and ensures that the base 2 is firmly fixed on the ground. The operator manually rotates the spring coil 602 to compress it to generate pressure, and adjusts the lifting direction. The hydraulic movement of the hydraulic lifting rod 401 and the load-bearing rod 402 allows the cylinder body 1 to be lifted and lowered in the vertical direction, so that the main lifting rod 504 bears the main load after grabbing. When adjusting the lifting object, the inclined rod 505 and the hydraulic rod 506 play an auxiliary force role on the main lifting rod 504. The grabbing mechanism 6 is located at the front end of the lifting mechanism 5. After the lifting mechanism 5 is subjected to force, the operator can adjust the position and direction of the grasping mechanism 6 to grasp the target object. The fixed grasping 608 in the grasping mechanism 6 is used to stabilize the target object. The rotating rod 607 and the fixed grasping 608 cooperate with each other in opposite directions so that they are just stuck at both ends of the I-beam. Then, as the ring fixing rod 604 drives the lifting handle 605, the entire front end lifting rod 606 moves upward as a whole to ensure that the object will not slide or fall off during the lifting process. When the lifting device completes the required operation, it moves the lifting device to the required position.
