Description

Technical Field

[0001] This utility model relates to the field of lifting frame technology, specifically an electromechanical lifting frame with a support structure. Background Technology

[0002] An electromechanical lifting frame is a mechanical device used to lift and support heavy objects. It can be used in industrial, commercial, and domestic environments, and is commonly found in fields such as automotive repair, warehousing and logistics, and construction. It can lift electromechanical products to facilitate their inspection and maintenance.

[0003] When inspecting and maintaining electromechanical equipment, it is necessary to lift the equipment using an electromechanical lifting frame and then inspect the bottom of the equipment. When using existing electromechanical lifting frames, the four sets of support frames at the bottom are unfolded to make them contact the ground and support the electromechanical lifting frame by increasing the ground contact area. However, the four sets of support frames need to be pulled and unfolded separately, which is quite cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide an electromechanical lifting frame with a support structure.

[0005] This utility model is achieved through the following measures: an electromechanical lifting frame with a support structure, characterized in that it includes a base, a lifting plate disposed above the base, and a drive mechanism for lifting the lifting plate up and down;

[0006] A bidirectional threaded rod is rotatably mounted on the base via a bearing in the middle of the interior. Connecting rods are threaded to both ends of the bidirectional threaded rod. The base has a movable groove that mates with the connecting rod. Through grooves are opened at both ends of the connecting rod. Protrusions are movably mounted in the through grooves. A support frame is fixedly connected to the bottom of the protrusion. A connecting shaft is fixedly mounted on the base near the bottom of the support frame. The connecting shaft is rotatably mounted on the base via a bearing.

[0007] Furthermore, the support frame includes a rotating rod and a fixed rod fixedly disposed at the outer end of the rotating rod, and the end of the fixed rod away from the connecting shaft is provided with a first threaded rod by a threaded connection.

[0008] Furthermore, a support block is fixedly provided at the lower end of the first threaded rod.

[0009] Furthermore, the base is provided with a rotating groove that cooperates with the rotating rod.

[0010] Furthermore, positioning plates are symmetrically arranged on both sides of the lifting plate, and a second threaded rod is threadedly connected to the positioning plate. One end of the second threaded rod is fixedly connected to a limiting plate to prevent the second threaded rod from disengaging from the positioning plate.

[0011] Furthermore, the positioning plate is mounted on the side wall of the lifting plate via a hinge, and a movable block is provided on the side of the positioning plate near the lifting plate. A storage groove is provided on the side wall of the lifting plate, and the storage groove is slidably connected to the movable block.

[0012] Furthermore, the drive mechanism includes a hydraulic cylinder and a scissor lift driven by the hydraulic cylinder.

[0013] Furthermore, a scissor lift generally includes an X-shaped linkage hinge unit. One end of the X-shaped linkage hinge unit is hinged to the lifting plate and the base respectively, and the other end of the X-shaped linkage hinge unit is slidably mounted on the lifting plate and the base respectively through guide posts. The lifting plate and the base are provided with strip-shaped openings that cooperate with the guide posts.

[0014] Compared with existing technologies, the beneficial effects of this electromechanical lifting frame with a support structure are as follows: By rotating a bidirectional threaded rod and engaging two sets of connecting rods through threaded transmission, the moving connecting rods actuate the protrusions, thereby causing the rotating rod to rotate around the connecting shaft. This, in turn, unfolds the fixed rods connected to the rotating rod outwards from the base. The two connecting rods can drive four sets of fixed rods to rotate and unfold synchronously. When all four sets of fixed rods are fully unfolded, they provide stable support for the electromechanical lifting frame. In other words, this application can achieve the synchronous unfolding of all support frames. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. Of course, the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0024] See Figures 1-6 An electromechanical lifting frame with a support structure is characterized by comprising a base 1, a lifting plate 4 disposed above the base 1, and a drive mechanism for lifting the lifting plate 4 up and down.

[0025] A bidirectional threaded rod 5 is rotatably mounted on the center of the base 1 via a bearing. Connecting rods 6 are threadedly connected to both ends of the bidirectional threaded rod 5. The base 1 has a movable groove that mates with the connecting rods 6. Through grooves are opened at both ends of the connecting rods 6. Protrusions 7 are movably mounted in the through grooves. A support frame 8 is fixedly connected to the bottom of the protrusions 7. A connecting shaft 9 is fixedly mounted on the bottom of the support frame 8 near the protrusions 7. The connecting shaft 9 is rotatably mounted on the base 1 via a bearing.

[0026] The support frame 8 includes a rotating rod and a fixed rod fixedly installed at the outer end of the rotating rod. The end of the fixed rod away from the connecting shaft 9 is provided with a first threaded rod 10 through a threaded connection.

[0027] A support block 11 is fixedly installed at the lower end of the first threaded rod 10.

[0028] The base 1 has a rotating groove that cooperates with the rotating rod.

[0029] In practice, when repairing electromechanical equipment, it is necessary to lift the equipment using an electromechanical lifting frame and then repair the bottom of the equipment. To ensure the stability of the electromechanical lifting frame during use, the two-way threaded rod 5 is rotated to drive the two sets of connecting rods 6 together. When the connecting rods 6 move, they will move by moving the protrusions 7 through the through slots on both sides. Since the protrusions 7 and the connecting shaft 9 at the bottom of the connecting rods 6 are misaligned, the rotating rod can be rotated around the connecting shaft 9 by moving the protrusions 7, thereby causing the fixed rods to unfold outward from the base 1. When the four sets of fixed rods are fully unfolded, the distance between the fixed rods can be increased. The support block 11 under the fixed rods can provide stable support for the electromechanical lifting frame.

[0030] When the ground is uneven, by rotating the first threaded rod 10 on the top of the support block 11 that is not in contact with the ground, the first threaded rod 10 will engage in threaded transmission with the fixed rod. The first threaded rod 10 will drive the support block 11 to move downward, so that the support block 11 contacts the ground, thus completing the stable support of the base 1. In this way, the electromechanical lifting frame can be stably supported to prevent it from tipping over during use.

[0031] Example 2:

[0032] See Figures 1-6 Based on Embodiment 1, positioning plates 12 are symmetrically arranged on both sides of the lifting plate 4. A second threaded rod 13 is provided on the positioning plate 12 by threaded connection, and a limit plate 14 is fixedly connected to the inner end of the second threaded rod 13.

[0033] The positioning plate 12 is mounted on the side wall of the lifting plate 4 via a hinge. A movable block 15 is provided on the side of the positioning plate 12 near the lifting plate 4. A storage groove is provided on the side wall of the lifting plate 4 and the storage groove is slidably connected to the movable block 15.

[0034] In practice, when repairing electromechanical equipment, it is necessary to lift the equipment using an electromechanical lifting frame and then repair the bottom of the equipment. When a narrow piece of equipment is placed on the lifting plate 4 for lifting, a positioning plate 12 is rotated to limit its movement by rotating the hinge on one side. When the plane on one side of the positioning plate 12 contacts the plane on one side of the lifting plate 4, it will stop rotating. At this time, the moving block 15 can be pulled to slide out of the lifting plate 4. After it is moved out, the top plane of the moving block 15 will contact the bottom plane of the positioning plate 12, limiting the positioning plate 12 and preventing it from rotating back to its original position. At this time, the second threaded rod 13 can be rotated to drive the positioning plate 12. When the limiting plate 14 at one end of the second threaded rod 13 contacts the equipment, it can limit its movement.

[0035] When the mechanical and electrical equipment on the top of the lifting plate 4 is wide, in order to prevent the positioning plate 12 from affecting the placement of the mechanical and electrical equipment, the moving block 15 is pushed back into the storage slot of the lifting plate 4 to remove the restriction on the positioning plate 12. Then the positioning plate 12 is rotated to reset. At this time, the positioning plate 12 will not cause a protrusion at the edge of the top of the lifting plate 4, and the mechanical and electrical equipment can be placed. In this way, the above operation can facilitate the maintenance of mechanical and electrical equipment of different sizes.

[0036] Example 3:

[0037] See Figures 1-6Based on Embodiment 1 or Embodiment 2, the driving mechanism includes a hydraulic cylinder 2 and a scissor lift frame driven by the hydraulic cylinder 2. The scissor lift frame generally includes an X-shaped linkage hinge unit 3. One end of the X-shaped linkage hinge unit 3 is hinged to the lifting plate and the base 1 respectively, and the other end of the X-shaped linkage hinge unit 3 is slidably mounted on the lifting plate and the base 1 via guide posts. The lifting plate and the base 1 are provided with strip-shaped openings that cooperate with the guide posts. In specific use, the hydraulic cylinder 2 is activated to push the X-shaped linkage hinge unit 3 to unfold, and pushes the lifting plate 4 upwards to lift the electromechanical equipment on the lifting plate 4.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
