Description

Technical Field

[0001] This utility model relates to the field of suspension beam technology, specifically a suspension beam with a telescopic structure. Background Technology

[0002] A gantry crane is a type of bridge crane with a horizontal bridge frame supported by two legs, forming a portal frame shape. This type of crane runs on ground rails and is mainly used for material handling and installation operations in open-air storage yards, shipyards, power plants, ports, and railway freight stations. The lifting range of a gantry crane is limited by the length of its lifting beam. Generally, the lifting beam length of a gantry crane is fixed. During lifting operations, the moving trolley can only move within a limited area below the lifting beam, thus restricting the lifting range and causing inconvenience to the lifting work.

[0021] 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.

[0022] Please see Figure 1-3 This utility model provides a lifting beam with a telescopic structure, including a main beam frame 1 and a telescopic beam frame 4 for telescopic adjustment of the lifting distance. The front side wall of the main beam frame 1 is provided with a side support seat 2 for supporting a mobile crane. The top of the side support seat 2 is provided with a main moving rail groove 21 for improving the stability of the mobile crane. The front side wall of the main beam frame 1 is provided with a mounting seat 3 for connecting with a support frame near the end. The left end of the main beam frame 1 is provided with a telescopic beam frame 4 for expanding the moving range of the mobile crane. The top of the telescopic beam frame 4 is provided with a secondary moving rail groove 22 for supporting the stable movement of the mobile crane.

[0023] A telescopic groove 42 is provided on the front side wall of the main beam frame 1, located to the left of the side support 2. A telescopic clamp 41 is provided on the inner wall of the telescopic beam frame 4. The telescopic beam frame 4 is slidably engaged with the main beam frame 1 through the cooperation of the telescopic clamp 41 and the telescopic groove 42. A connecting pin 5 is installed on the top of the telescopic beam frame 4. A side limiting groove 51 is provided on the front side wall of the connecting pin 5. A top sliding groove 52 is provided on the top of the main beam frame 1. The connecting pin 5 is movably inserted into the main beam frame 1 through the cooperation of the side limiting groove 51 and the top sliding groove 52. A telescopic motor 6 is installed on the top of the main beam frame 1 to control the telescopic movement of the telescopic beam frame 4 and the connecting pin 5.

[0024] Furthermore, an adjusting threaded shaft 61 is installed at the output end of the adjusting telescopic motor 6, and an adjusting threaded groove 62 is provided on the right side wall of the connecting pile 5. The adjusting threaded shaft 61 is connected to the adjusting threaded groove 62 by threads. The threads of the adjusting threaded shaft 61 and the adjusting threaded groove 62 are compatible. When the adjusting telescopic motor 6 drives the adjusting threaded shaft 61 to rotate, the adjusting threaded shaft 61 drives the connecting pile 5 to move laterally through the cooperation with the adjusting threaded groove 62, thereby adjusting the position of the connecting pile 5 and the telescopic beam 4.

[0025] Furthermore, a limiting head 53 is installed on the right side of the front wall of the connecting pile 5, and a limiting pile 54 is installed on the top of the main beam frame 1 to limit the leftward movement of the limiting head 53. When the connecting pile 5 moves to the left, it drives the limiting head 53 to move synchronously. After the limiting head 53 moves to a position close to the right side of the limiting pile 54, the limiting pile 54 blocks the limiting head 53, thereby limiting the movement range of the connecting pile 5 and maintaining a safe insertion length between the connecting pile 5 and the main beam frame 1, thus ensuring the stability of the hoisting work.

[0026] Furthermore, the mobile crane is installed below the main beam frame 1 via the main moving rail groove 21, and the auxiliary moving rail groove 22 is connected to the main moving rail groove 21. The moving wheels of the mobile crane are engaged inside the main moving rail groove 21 and the auxiliary moving rail groove 22 for movement.

[0027] Furthermore, a pressure sensor is installed on the bottom inner wall of the auxiliary moving track 22, located on the left side. After the mobile crane moves along the auxiliary moving track 22 to the leftmost position, it presses the pressure sensor. When the pressure sensor is pressed, it can control the telescopic motor 6 to drive the telescopic beam 4 and the connecting pin 5 to move laterally. When the pressure sensor is not pressed, it cannot control the telescopic motor 6 to rotate, thus preventing the mobile crane from falling through the gap between the main moving track 21 and the auxiliary moving track 22 after they are disconnected. After the telescopic beam 4 and the connecting pin 5 move to the left, before the telescopic beam 4 and the connecting pin 5 return to their original position and rejoin the main beam 1, the left and right movements of the mobile crane are achieved by controlling the telescopic beam 4 and the connecting pin 5 to extend and retract.

[0028] Furthermore, the bottom inner wall of the telescopic head 41 and the top inner wall of the top sliding groove 52 are both inlaid with movable steel balls, and the bottom inner wall of the telescopic groove 42 and the bottom inner wall of the side limiting groove 51 are both provided with grooves for the steel balls to move. Through the cooperation of the movable steel balls and the grooves, the stability of the telescopic beam frame 4 and the connecting pile 5 during lateral movement is improved, and the frictional resistance during movement is reduced.

[0029] In use, the mounting base 3 is installed and connected to the mobile frame with bolts. The mobile crane is clamped on the outside of the side support 2, and the mobile crane's wheels are clamped inside the main moving rail groove 21. During the lifting operation, the mobile crane moves along the main moving rail groove 21 to move the goods left and right for lifting. The lifting range can also be further expanded by controlling the mobile frame to move forward and backward. When it is necessary to expand the lifting range, the mobile crane is controlled to move to the leftmost position of the auxiliary moving rail groove 22, so that the mobile crane presses on top of the pressure sensor. After the pressure sensor is pressed, it releases the restriction on the control telescopic motor 6, and the control telescopic motor 6 is energized to drive the control threaded shaft 61 to rotate. The rotation of the control threaded shaft 61 drives the connecting pile 5 to move laterally through the control threaded groove 62. The connecting pile 5 and the telescopic beam 4 move laterally, thereby supporting the mobile crane to move to the left, expanding the maximum lateral movement range of the mobile crane. Then, the mobile crane is controlled to lower the goods to complete the lifting operation.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
