Detailed Description

The first embodiment.

This embodiment aims at providing hoisting machine structure 1 that can hoist and mount jumbo size frame (support) structure product, solves the problem of the unable better adaptation of current hoist and mount scheme, because current electromagnetic adsorption hoist and mount scheme can't be suitable for this kind of frame structure product, consequently proposes this embodiment.

The method of use of this example is as follows:

starting the travelling crane 2 to drive the hoisting mechanism 3 to move above the processed product; 2. the main lifting rope 4 is put down, so that the hanging component 7 and the overturning component 8 under the expansion frame 5 are close to the product; 3. mounting the mounting component 7 on the frames at two sides of the product, and mounting the overturning component 8 on the frame at the front side or the rear side of the product; 4. when the product needs to be turned over, the wire coil 14 is started to rotate and receive the auxiliary lifting rope 6, and one side of the product on which the turning assembly 8 is mounted is lifted; 5. when the overturning assembly 8, the auxiliary lifting rope 6 connected with the assembly and the wire coil 14 are positioned on the same straight line, the wire coil 14 stops rotating; 6. at the moment, the other side of the product without the loading and overturning assembly 8 is held by hands, the wire coil 14 is started again to release the auxiliary lifting rope 6, and meanwhile, the held side is pulled forcefully, so that the product is overturned; 7. the lifting mechanism 3 is started to drive the product to descend onto the table top of the workbench, and the overturning assembly 8 and the mounting assembly 7 are disassembled at the moment to complete the overturning operation of the product.

The main body of the mounting component 7 is a clamping plate 9 in a U shape, the clamping plate can be of an integrally formed structure, a traditional electromagnetic adsorption device 10 is arranged in the clamping plate 9, a common micro electromagnet is specifically adopted, and the electromagnetic adsorption device 10 is arranged on the inner side outer edge of the clamping plate 9. The mounting method of the mounting component 7 is to sleeve the clamping plate 9 from the bottom of the product side frame, and then start the electromagnetic adsorption device 10 to adsorb the sleeved frame to prevent the frame from separating from the clamping plate 9.

One side of the clamping plate 9 is hinged with the auxiliary lifting rope 6 through a hinge piece, so that when a product is turned, the auxiliary lifting rope 6 connected with the clamping plate 9 is not moved, and the clamping plate 9 is turned along with the product. The circuit for supplying power to the electromagnetic adsorption device 10 may be wound on the auxiliary hoist rope 6, and since the posture of the auxiliary hoist rope 6 itself is stable, power may be stably supplied.

The main body of the turnover assembly 8 is a clamp member 11, the structure of the clamp member 11 is the same as that of a clamp member 11 commonly used for pipeline connection, but the clamp member 11 in the embodiment is wider than the existing product in the transverse width, so that the wider structure can stably carry the product and provide more sufficient installation space for a guide rail 12 on the product. The auxiliary lifting rope 6 for lifting the hoop member 11 is connected to the slide block 13 of the guide rail 12, and the hoop member 11 is also hooped on the frame at the side of the product, so when the product is overturned, the slide block 13 slides around the guide rail 12 under the pulling of the auxiliary lifting rope 6, the auxiliary lifting rope 6 can be always positioned above the product, and the product is prevented from being pressed below or wound at other places. It should be noted that the above-mentioned effects are only achieved when the wire coil 14 pulls up the clip member 11 and tilts the product toward the wire coil 14, and if the auxiliary lifting rope 6 is first paid out from the wire coil 14, the clip member 11 is inclined downward, and the auxiliary lifting rope 6 is located below the product after the product is turned over.

In this embodiment, there is a preferable example that the shape of the extension frame 5 is a triangular shape. As shown in fig. 2, since the processed product is mostly a processing table of a square frame mechanism, the processing table forms a frame of a basic shape, and the middle of the finished product is hollowed out when the finished product is delivered, so that the finished product can be mounted on the side by the mounting component 7 and the overturning component 8. According to the situation, the shape of the expansion frame 5 can be set to be triangular, and the product can be turned only by at least two mounting assemblies 7 and at least one turning assembly 8. However, this preferred embodiment is merely an example, and the shape of the expansion rack 5 can be adjusted according to the actual shape of the product, and more mounting assemblies 7 and flipping assemblies 8 are added to the expansion rack 5 to realize the expansion function of the expansion rack 5.

This embodiment still has the preferred embodiment, sets up fixed sleeve 15 at vice lifting rope 6 end promptly, and grip block 9 articulates on fixed sleeve 15, has solved vice lifting rope 6 and has directly connected the poor problem of grip block 9 upset stability when the articulated elements. The fixed sleeve 15 is provided with a rotating hole 16, the rotating hole 16 is provided with a rotating shaft, the clamping plate 9 is connected to the rotating shaft and rotates by taking the rotating shaft as a center, and when the clamping plate 9 rotates, the fixed sleeve 15 is of a hard structure and is provided with a weight, so that the fixed sleeve 15 is not easy to be hooked by a product like a lifting rope to cause bending or winding when the clamping plate 9 is turned.

Example two.

The present embodiment is made on the basis of the first embodiment, and aims to improve the practicability of the reversible hoisting mechanism 1.

In the embodiment, the structure of the fixing sleeve 15 is further improved, so that the practicability of the whole mounting assembly 7 is greatly improved.

In order to achieve the above effects, a plurality of rotation holes 16 may be further formed on the basis of the original single rotation hole 16 of the fixing sleeve 15, and the diameter size of the fixing sleeve 15 is limited, so that if the rotation holes 16 are arranged on the same horizontal plane, the depth of the rotation hole 16 is insufficient, and the fixing effect of the rotation shaft is poor. The solution is to arrange the rotary holes 16 in a staggered manner. Correspondingly, a plurality of clamping plates 9 are provided, and the clamping plates 9 with high height and the clamping plates 9 with normal height can be provided according to different heights of the rotary holes 16.

In order to cope with more products with different structures and better play a role, the outer wall of the fixed sleeve 15 is provided with a lantern ring 17 capable of rotating, the lantern ring 17 and the fixed sleeve 15 are coaxially arranged, the lantern ring 17 and the fixed sleeve 15 are both provided with limiting measures for limiting the separation of the lantern ring 17 and the fixed sleeve 15, and the limiting measures can adopt the existing scheme at will. A threaded through hole 18 on the collar 17 replaces the original rotary hole 16 and a custom screw 19 mounts the clamping plate 9 on the threaded through hole 18. The customized screw 19 needs to play a role of fixing the clamping plate 9 (a threaded section 20), and also plays a role of rotating a rotating shaft (a smooth section 21) for rotating the clamping part, and an annular blocking piece 22 is arranged at the tail end of the smooth section 21, namely, at one end far away from the fixing sleeve 15, so that the clamping plate 9 is limited to be separated from the customized screw 19.
