Detailed Implementation

[0021] Please see Figures 1-5 This utility model provides a technical solution: a precise control structure for the suspension of a flat clamp, including a clamp body 1 and an anti-slip clamp 2. The anti-slip clamp 2 is fixedly connected to the lower inner wall of the clamp body 1. A clamp 3 is rotatably connected to the inner wall of the clamp body 1. A fixing block 4 is fixedly connected to the inner wall of the clamp body 1. A limit spring 5 is fixedly connected to the inclined surface of the fixing block 4. The end of the limit spring 5 away from the fixing block 4 is fixedly connected to the surface of the clamp 3. An assisting component 6 is provided on the rear side of the clamp body 1.

[0022] In this embodiment: the assisting component 6 includes a connecting frame 61, which is fixedly connected to the inner wall of the clamp body 1. A connecting post 62 is fixedly connected to the upper surface of the connecting frame 61, and a lead screw 63 is fixedly connected to the upper surface of the connecting post 62. A horizontal plate 64 is installed at the end of the lead screw 63 away from the connecting post 62. A limiting sleeve 65 is fixedly connected to the upper surface of the horizontal plate 64. A driving sleeve 66 is rotatably connected to the inner wall of the limiting sleeve 65. The inner wall of the driving sleeve 66 is threaded, and the driving sleeve 66 is threadedly connected to the lead screw 63.

[0023] The assisting component 6 also includes a protective cover 67, which is fixedly connected to the upper surface of the cross plate 64. A servo motor 68 is fixedly connected to the upper surface of the protective cover 67. A transmission gear 69 is mounted on the surface of the drive shaft of the servo motor 68, and the transmission gear 69 meshes with the tooth groove of the drive sleeve 66.

[0024] Specifically, a load-bearing frame 610 is fixedly connected to the side of the connecting frame 61 away from the clamp body 1, and the load-bearing frame 610 is fixedly connected to the surface of the lead screw 63.

[0025] In this embodiment, the support structure between the lead screw 63 and the connecting frame 610 can be increased by the load-bearing frame 610, thereby improving the structural strength of the connection between the lead screw 63 and the connecting frame 61 and increasing the load-bearing capacity of the lead screw 63.

[0026] Specifically, a guide sleeve 611 is fixedly connected to the lower surface of the horizontal plate 64. The guide sleeve 611 is sleeved with the surface of the lead screw 63. A guide groove 612 is provided on the surface of the lead screw 63. A protrusion is provided inside the guide sleeve 611. The protrusion of the guide sleeve 611 is slidably connected to the inner wall of the guide groove 612. Through the cooperation of the guide sleeve 611 and the guide groove 612, the movement direction of the lead screw 63 can be guided, and the problem of the lead screw 63 being difficult to effectively engage the threads by following the rotation of the drive sleeve 66 can be reduced.

[0027] In this embodiment: the lead screw 63 passes through the upper surface of the horizontal plate, and the lead screw 63 is slidably connected to the inner wall of the protective cover 67.

[0028] In this embodiment: the lead screw 63 can be driven upward by the drive sleeve 66 during the rotation of the drive sleeve 66, thereby pulling the lower structure to move.

[0029] Specifically, the drive sleeve 66 is located inside the protective cover 67 and is in contact with the upper surface of the cross plate 64. The protective cover 67 can protect the meshing parts of the drive sleeve 66 and the transmission gear 69 to ensure the safety of both in the working state.

[0030] Specifically, the drive end of the servo motor 68 penetrates the upper inner wall of the protective cover 67, and the transmission gear 69 is located inside the protective cover 67.

[0031] In this embodiment, the servo motor 68 can drive the transmission gear 69 to work when it is powered on, so that the transmission gear 69 can stably mesh with the drive sleeve 66 for transmission.

[0032] Working principle: When working, push the clamp 3 towards the limit spring 5. The clamp 3 is pressed against the limit spring 5. The limit spring 5 is deformed by the compression and loses its constraint on the clamp 3. The clamp 3 is unrestrained and rotates under force and gradually unfolds. After the clamp 3 unfolds, place the material to be lifted into the clamping area formed by the anti-slip plate 2 and the clamp 3. Then release the clamp 3. The clamp 3 loses the pressure applied to the limit spring 5. The limit spring 5 loses the pressure and rebounds, pushing the clamp 3 to reset. After resetting, the clamp 3 is placed above the material to cooperate with the anti-slip plate 2 to clamp the material.

[0033] Before using the device, bolts are used to fix the horizontal plate 64 to the moving mechanism of the gantry crane. After installation, the gantry crane and the lifting clamp can be connected via the assist component 6. During use, when the user completes the clamping operation, the servo motor 68 is switched on. The servo motor 68 is powered on and drives the transmission gear 69. The transmission gear 69 rotates and meshes with the drive sleeve 66. The drive sleeve 66 rotates in a specified direction under the constraint of the limit sleeve 65. During rotation, it meshes with the lead screw 63 via threads. The lead screw 63 guides... Guided by the sleeve and guide groove 612, the connecting column 62 pulls the load frame 610 and the connecting frame 61 in the specified direction. The connecting frame 61 pulls the clamp body 1 under the force. Under the action of the connecting frame 61, the clamp body 1, together with the anti-slip clamp plate 2 and clamp 3, pulls the material upward. When the material is pulled to the specified height, the servo motor 68 is turned off, the transmission gear 69 stops meshing with the drive sleeve 66, the drive sleeve 66 stops rotating, and the position of the lead screw 63 is locked. When the lead screw 63 is locked, the position of the clamp body 1 and the material can be restricted.

[0034] When the material is confined to a specified height, the operator can control the gantry crane to move. The gantry crane's moving mechanism, in conjunction with the assisting component 6 and the flat lifting clamp, moves the material. By setting the assisting component 6, the flat lifting clamp can be rigidly connected to the gantry crane, so that the flat lifting clamp is not affected by the inertia of the material during movement. This reduces the problem of inaccurate hovering position caused by inertial interference when the flat lifting clamp is connected by a chain, thus effectively improving the hovering accuracy of the flat lifting clamp.
