Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lifting equipment technology, specifically relating to a special lifting equipment for motor brackets that can reduce swaying. Background Technology
[0002] In the manufacturing process of motor brackets, in order to achieve precise transfer and positioning of workpieces, specially designed lifting devices are usually used to perform clamping and hoisting operations. The core structure of such lifting devices includes a lifting device at the top, a force transmission component in the middle, and a clamping mechanism at the bottom. Among them, the connecting rod used to connect the lifting device and the clamping mechanism is a key component to ensure the overall force balance.
[0003] However, existing lifting devices require a sufficiently long connecting rod to allow the clamping section at the bottom of the device to open wide enough. Once the lifting device has clamped the motor bracket, the excessively long connecting rod is highly susceptible to high-frequency, variable-amplitude vibrations during workpiece movement due to external environmental disturbances (such as airflow disturbances in the workshop or inertial impacts from crane operation) or minor swaying during lifting operations. This vibration is not isolated but is directly transmitted to the clamping section at the bottom of the lifting device through the rigidity of the connecting rod.
[0004] The additional radial force generated by the vibration causes the contact point between the gripper and the motor bracket to continuously undergo slight displacement, resulting in periodic fluctuations in the gripping force. This loosens the originally tight gripping relationship and reduces the reliability of the gripping. Utility Model Content
[0005] The purpose of this invention is to provide a dedicated lifting tool for motor brackets that reduces swaying. It addresses the problem that after the lifting tool has clamped the motor bracket, the excessively long connecting rod is prone to high-frequency, variable-amplitude vibrations during workpiece movement due to external environmental interference or minor swaying during lifting operations. This vibration is not isolated but is transmitted directly to the clamping portion at the bottom of the lifting tool through the rigidity of the connecting rod. The additional radial force generated by the vibration causes continuous minute displacements at the contact point between the clamping jaws and the motor bracket, resulting in periodic fluctuations in clamping force. This loosens the originally tight clamping relationship, thus reducing the reliability of the clamping.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a special lifting device for motor brackets that can reduce swaying, including a lifting device frame, wherein a movable rod is movably installed through the center end of the lifting device frame, and two connecting rods are rotatably installed at the bottom of the movable rod, and the other end of the connecting rod is movably connected to one side of the outer wall of the lifting device frame; The center end of the connecting rod is movably connected to the bottom of the reinforcing rod, the top end of the reinforcing rod is movably sleeved inside the positioning sleeve, one side of the positioning sleeve is fixedly installed on the outer wall of one side of the top of the lifting frame, and two insert plates are movably inserted into one side of the positioning sleeve, and a clamping plate is fixedly installed between the two insert plates.
[0007] In order to enable the connecting rod to rotate into the movable recess when the workpiece is clamped at the bottom of the lifting frame, as a special lifting tool for motor bracket that can reduce sway in this utility model, preferably, the bottom of the reinforcing rod is provided with a recessed movable recess, and a movable pin is movably inserted through the outer wall of the reinforcing rod near the bottom. The reinforcing rod can be rotatably mounted on the connecting rod by means of the movable recess and the movable pin.
[0008] In order to fix the position of the reinforcing rod and keep it stationary in the positioning sleeve, as a special lifting tool for motor bracket that can reduce sway in this utility model, preferably, the positioning sleeve has two insertion holes on the side away from the docking end of the lifting tool frame, and the insertion plate is inserted into the interior of the positioning sleeve through the insertion holes to dock with the reinforcing rod; A set of insertion holes are equally spaced on the outer wall of the joint end of the reinforcing rod and the insert plate, and the insertion holes located inside the positioning sleeve are inserted into one end of the insert plate.
[0009] In order to fix the card plate to the positioning sleeve, as a special lifting tool for motor bracket that can reduce shaking in this utility model, preferably, positioning strips are glued to both ends of the card plate facing the outer wall of the positioning sleeve, and the card plate is made of deformable metal material; The positioning sleeve has a positioning hole on each of its left and right outer walls that is adapted to the positioning strip. The card plate is fixedly mounted on the positioning sleeve by the insertion between the positioning strip and the positioning hole.
[0010] Compared with the prior art, the beneficial effects of this utility model are: In use, align the top of the movable rod on the spreader frame with the bottom of the lifting equipment, and then place the clamping part at the bottom of the spreader frame on both sides of the motor bracket to be lifted. As the lifting equipment moves upward, the movable rod will pull one end of the bottom connecting rod upward, thus allowing the bottom of the spreader frame to retract inward and clamp the motor bracket. As one end of the connecting rod moves upward with the movable rod, the connecting rod simultaneously drives the reinforcing rod upward, with the top of the reinforcing rod passing through the interior of the positioning sleeve and moving upward. Once the lifting frame has stabilized the motor bracket, the two sets of insert plates are inserted into the positioning sleeve and align with the slots on the reinforcing rod. This fixes the reinforcing rod inside the positioning sleeve, and the fixation of the reinforcing rod also helps to stabilize the connecting rod. This allows the connecting rod to remain more securely in its tilted position, reducing swaying during movement and improving clamping stability. Attached Figure Description

[0016] 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.
[0017] Please see Figure 1-4 The present invention provides the following technical solution: a special lifting device for motor bracket that can reduce swaying, including a lifting device frame 1, a movable rod 2 is movably installed through the center end of the lifting device frame 1, two connecting rods 3 are rotatably installed at the bottom of the movable rod 2, and the other end of the connecting rod 3 is movably connected to one side of the outer wall of the lifting device frame 1. The center end of the connecting rod 3 is movably connected to the bottom of the reinforcing rod 4. The top end of the reinforcing rod 4 is movably sleeved inside the positioning sleeve 5. One side of the positioning sleeve 5 is fixedly installed on the outer wall of one side of the top of the lifting frame 1. Two insert plates 6 are movably inserted into one side of the positioning sleeve 5. A clamping plate 7 is fixedly installed between the two insert plates 6.
[0018] The lateral space inside the positioning sleeve 5 is larger than the diameter of the reinforcing rod 4. When in use, the lateral space inside the positioning sleeve 5 will be adapted to the maximum tilt angle of the reinforcing rod 4.
[0019] Preferably, the bottom of the reinforcing rod 4 has a recessed movable notch 42, and a movable pin 43 is movably inserted through the outer wall of the reinforcing rod 4 near the bottom. The reinforcing rod 4 can be rotatably mounted on the connecting rod 3 through the movable notch 42 and the movable pin 43.
[0020] In practical use, when the movable rod 2 moves upward via the lifting device, it will cause the connecting rod 3 to retract towards the center. When the connecting rod 3 retracts, it will tilt further. In this way, the tilted connecting rod 3 will move into the interior of the movable recess 42, so that when the connecting rod 3 rotates, it will drive the reinforcing rod 4 to rotate. Preferably, the positioning sleeve 5 has two insertion holes 51 on the side away from the docking end of the lifting frame 1, and the insertion plate 6 is inserted into the interior of the positioning sleeve 5 through the insertion holes 51 and docks with the reinforcing rod 4; A set of insertion ports 41 are provided at equal intervals on the outer wall of the joint end of the reinforcing rod 4 and the insertion plate 6. The insertion ports 41 located inside the positioning sleeve 5 are inserted into one end of the insertion plate 6.
[0021] In practical use, after the position of the reinforcing rod 4 is initially fixed by the rotation of the connecting rod 3, the two insert plates 6 on the clamping plate 7 are inserted into the insertion holes 51. The insert plates 6 will pass through the insertion holes 51 and mate with the insertion port 41. The positioning strips 71 at both ends of the clamping plate 7 will engage with the positioning holes 52, thus ensuring that the insert plates 6 and the insertion holes 51 are in a stable insertion state.
[0022] Preferably, positioning strips 71 are bonded to both ends of the card plate 7 facing the outer wall of the positioning sleeve 5, and the card plate 7 is made of deformable metal material; A positioning hole 52 that matches the positioning strip 71 is opened on the outer wall of the left and right sides of the positioning sleeve 5. The card plate 7 is fixedly installed on the positioning sleeve 5 through the insertion between the positioning strip 71 and the positioning hole 52.
[0023] In practical use, the top of the movable rod 2 on the lifting frame 1 is aligned with the bottom of the lifting equipment, and then the clamping part at the bottom of the lifting frame 1 is placed on both sides of the motor bracket to be lifted. As the lifting equipment moves upward, the movable rod 2 will pull one end of the bottom connecting rod 3 upward, thus allowing the bottom of the lifting frame 1 to retract inward and clamp the motor bracket. As one end of the connecting rod 3 moves upward with the movable rod 2, the connecting rod 3 simultaneously drives the reinforcing rod 4 upward, and the top of the reinforcing rod 4 moves upward through the interior of the positioning sleeve 5. After the lifting frame 1 clamps the motor bracket stably, the two sets of insert plates 6 are inserted into the positioning sleeve 5 and align with the inserts 41 on the reinforcing rod 4. In this way, the reinforcing rod 4 is fixed inside the positioning sleeve 5, and the fixed reinforcing rod 4 also has a fixing effect on the connecting rod 3. This allows the connecting rod 3 to remain more stably in the inclined state, thereby reducing the shaking of the connecting rod 3 during movement and improving the clamping firmness.
[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
