Description

Technical Field

[0001] The present application relates to the technical field of suspension equipment, and in particular to a sling. Background Art

[0002] The engine is assembled from multiple parts, including the engine housing, rocker arms, rocker arm shafts and other parts. After the relevant parts are produced, the parts need to be transported to the assembly station and assembled uniformly at the conveying station to obtain a complete vehicle engine.

[0003] In the related technology, during the transportation process, it is usually necessary to use equipment such as cranes to suspend and transfer larger parts. When transferring larger parts, the operator first fixes the steel cable to the relevant position of the workpiece, and then fixes the end of the steel cable to the crane. Then, the crane is driven to move, thereby driving the steel cable to move, thereby realizing the transfer operation of the parts.

[0004] With regard to the above-mentioned related technologies, when transferring parts, operators can only connect the outside of the parts using steel cables. During the transfer process, slippage may occur, thereby affecting the fixation effect of the workpiece, easily causing safety hazards, and making it inconvenient for operators to transfer the workpiece. Utility Model Content

[0005] In order to better connect and fix the workpieces, improve the reliability of workpiece transfer, and prevent the workpieces from falling, the present application provides a sling.

[0006] The present application provides a sling, which adopts the following technical solution:

[0007] A sling comprises a fixing device and a locking device;

[0008] The fixing device comprises a plurality of fixing rods, the fixing rods are connected to the crane, each of the fixing rods is provided with a limiting rod, the limiting rod is fixedly connected to the fixing rod, and the locking device is installed on one of the fixing rods;

[0009] The locking device comprises a limiting ring and a connecting rod, wherein the limiting ring is fixedly connected to the fixing rod, the connecting rod is passed through the limiting ring, the connecting rod is rotatably connected to the limiting ring, and the connecting rod elastically slides along the limiting ring;

[0010] The bottom of the connecting rod is fixedly connected with an extrusion plate.

[0011] By adopting the above technical solution, the fixing rod can provide support for the installation of the limiting rod, and the setting of the fixing rod makes it easy to connect the device to the corresponding position of the crane. The operator first inserts the end of the fixing rod and the limiting rod into the relevant structure of the workpiece. At this time, the extrusion plate is located in the relevant structure of the workpiece together with the limiting rod, and the limiting rod cannot slide. When the operator rotates the connecting rod along the fixing ring and slides along the fixing ring at the same time, the extrusion plate leaves the relevant structure of the workpiece, and the limiting rod can move along the relevant structure of the workpiece, so that the crane can be separated from the workpiece. The setting of the extrusion plate makes it easy for the operator to connect the workpiece and the crane, thereby improving the connection stability between the workpiece and the crane.

[0012] Optionally, a mounting plate is further included, wherein the fixing rods are evenly distributed circumferentially along the vertical direction, and the fixing rods are all fixedly connected to the mounting plate.

[0013] By adopting the above technical solution, the mounting plate provides support for the installation of the fixing rod, and multiple fixing rods are provided, thereby being able to provide a more stable connection effect for the workpiece, preventing the workpiece and the crane from slipping and causing certain safety hazards.

[0014] Optionally, the fixing device further comprises a plurality of support frames, the support frames are arranged in sequence along the vertical direction, and the support frames are fixedly connected to the fixing rod.

[0015] By adopting the above technical solution, the support frame can connect the fixed rods, thereby preventing the positions between the fixed rods from shifting to a certain extent during the process of hoisting the workpiece, thereby reducing the limiting effect of the fixed rods on the workpiece. A plurality of support rods are provided, which can further support the positions between the fixed rods and improve the stability of the limiting rods when connecting the workpiece.

[0016] Optionally, a receiving groove is provided at each corner of the support frame, the receiving groove is used to receive the fixing rod, and the fixing rod is fixedly connected to the support frame.

[0017] By adopting the above technical solution and setting the accommodating groove, the accommodating groove can accommodate the fixing rod, thereby increasing the contact area between the fixing rod and the supporting frame, thereby improving the connection stability between the fixing rod and the supporting frame.

[0018] Optionally, the connecting rod is equipped with a lifting plate and a reinforcing rib, the lifting plate and the connecting rod are fixedly connected, one end of the reinforcing rib is fixedly connected to the connecting rod, and the other end is fixedly connected to the lifting plate.

[0019] By adopting the above technical solution, the setting of the lifting plate makes it easier for the operator to rotate the connecting rod or elastically slide along the limiting ring, thereby controlling the rotation or displacement of the extrusion plate, thereby improving the operator's work efficiency. The setting of the reinforcing rib can enhance the connection stability between the connecting rod and the lifting plate and prevent the connecting rod and the lifting plate from loosening.

[0020] Optionally, the mounting plate is provided with a connecting plate, and the connecting plate is fixedly connected to the mounting plate;

[0021] The connecting plate is equipped with a support rod and a lifting lug, one end of the support rod is fixedly connected to the connecting plate, and the other end is fixedly connected to the lifting lug.

[0022] By adopting the above technical solution, the connecting plate can connect the support rod and the mounting plate, and the connecting plate can improve the connection between the support rod and the mounting plate. The support rod can connect the lifting lug and the connecting plate, and the operator can fix the lifting lug at the relevant position of the crane. The operator can shift the lifting lug through the crane, and then shift the device, and can shift the workpiece, thereby improving the moving efficiency of the workpiece and the working efficiency of the operator.

[0023] Optionally, the limiting rod is provided with a mounting groove, the inner cavity of the mounting groove is provided with an abutment plate and an elastic rod, one end of the elastic rod is fixedly connected to the limiting rod, and the other end is fixedly connected to the abutment plate.

[0024] By adopting the above technical solution, the mounting groove provides support for the installation of the abutment plate and the elastic rod. When the limiting rod is inserted into the relevant structure of the workpiece, the operator can adjust the length of the elastic rod so that the top wall of the abutment plate abuts against the relevant structure of the workpiece, thereby enabling the workpiece to be stably connected to the fixed rod and move with the crane.

[0025] Optionally, a guide groove is provided at one end of the top wall of the abutment plate away from the fixing rod.

[0026] By adopting the above technical solution, the operator inserts the limit rod into the relevant structure of the workpiece and sets the guide groove. As the abutment plate rotates with the limit rod, the relevant structure of the workpiece slides along the guide groove, thereby causing the elastic rod to contract, making it easier for the abutment plate to enter the relevant structure of the workpiece.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. By setting a locking device, the extrusion plate enters into the relevant structure of the workpiece, thereby fixing the position of the extrusion plate, so that the workpiece can be stably fixed on the hanger, and the workpiece can be transferred, thereby improving the stability of the workpiece transfer;

[0029] 2. By setting the lifting lugs, it is convenient for the crane to connect the lifting device and transfer the lifting device, and then the workpiece can be transferred, which improves the work efficiency of the operator;

[0030] 3. By providing the abutment plate, the connection stability with the workpiece can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The implementation principle of Example 1 is as follows: when the operator displaces the workpiece, the operator first places the workpiece on the table, and then places the extrusion plate 34 on the relevant structure of the workpiece. At this time, the extrusion plate 34 slides upward, and the spring 33 contracts. The operator rotates the fixing rod 21, so that the extrusion plate 34 enters the relevant structure of the workpiece. At this time, the spring 33 restores its original length, and then limits the position of the extrusion plate 34 to prevent the extrusion plate 34 from sliding in the relevant structure of the workpiece. At the same time, the workpiece is slid by the crane.

[0050] When the workpiece needs to be contact-limited, the operator rotates and pulls up the lifting plate 35, and the extrusion plate 34 withdraws from the relevant structure of the workpiece. The operator then rotates the fixing rod 21 in the opposite direction, and the extrusion plate 34 withdraws from the relevant structure of the workpiece. At this time, the workpiece is no longer connected to the sling.

[0051] Example 2

[0052] The difference between this embodiment and embodiment 1 is that in embodiment 1, there may be a certain gap between the extrusion plate 34 and the corresponding groove of the workpiece, and there may be a certain shaking during the lifting process, thereby affecting the lifting effect of the workpiece. This embodiment can further improve the connection effect between the workpiece and the extrusion rod.

[0053] Reference Figure 2 and Figure 3 The top wall of the limiting rod 24 is provided with a mounting groove 25 in the vertical direction, and the inner cavity of the mounting groove 25 is provided with a tightening assembly, which includes an abutment plate 26 and an elastic rod 27. The abutment plate 26 is horizontally arranged, and the length direction of the abutment plate 26 is parallel to the length direction of the mounting groove 25. In this embodiment, the number of elastic rods 27 is preferably two, the telescopic direction of the elastic rod 27 is consistent with the opening direction of the mounting groove 25, and the two elastic rods 27 are arranged in sequence along the length direction of the abutment plate 26, one end of the elastic rod 27 is fixedly connected to the abutment plate 26 by means of screws, and the other end is fixedly connected to the limiting rod 24 by means of screws.

[0054] Reference Figure 2 and Figure 3 A guide groove 28 is formed on the top wall of one end of the abutment plate 26 away from the fixing rod 21 . In this embodiment, the depth of the guide groove 28 gradually becomes shallower from the direction away from the fixing rod 21 to the direction close to the fixing rod 21 .

[0055] The implementation principle of a hanger in an embodiment of the present application is as follows: when the operator rotates the extrusion plate 34 into the relevant structure of the workpiece, the side wall of the guide groove 28 abuts against the side wall of the relevant structure of the workpiece, thereby causing the elastic rod 27 to contract and the top wall of the abutment plate 26 to abut against the relevant structure of the workpiece, further improving the connection stability between the workpiece and the hanger.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
