Description

Technical Field

[0001] The utility model relates to the technical field of steel grabbers, in particular to a steel grabber for waste metals. Background Technique

[0002] A steel grabber, as the name implies, refers to a machine for grabbing steel materials, which is generally evolved from a hydraulic excavator. The boom and stick of the steel grabber are commonly known as the "material grabbing arm", which is generally relatively long, and its front end is a steel grab, that is, a grabber, also called a plum blossom type hydraulic grab or an orange peel grab. In the waste metal recycling industry, the steel grabber is one of the common mechanical equipment in operations.

[0003] The prior art proposes that a steel grabber for waste metal recycling disclosed in Chinese Patent [Application No. CN202220242130.6] includes an L-shaped platform. One end of the L-shaped platform is provided with equally spaced installation openings, and the inner walls of the installation openings are all inserted with first grippers. An installation assembly is arranged between the first grippers and the installation openings. Both ends of one side of the top of the L-shaped platform are fixedly connected with fixing plates, and a rotating shaft is connected between the opposite sides of the fixing plates through a pin shaft; although this patent can press the clamping hoop on the waste metal by using the tensioning effect of the first spring, it can meet the requirement of grabbing a small amount of waste metal; however, there are certain defects in the above patent during use. For example, during the construction process, the sizes of waste metals are not the same, and the grippers of the above patent have a fixed interval and cannot be adjusted according to different waste metals or different scenarios where waste metals are placed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a steel grabber for waste metals.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

One side of the rotating rod is fixedly connected with a connecting plate. The other side of the connecting plate is fixedly connected with an adjusting mechanism. One side of the adjusting mechanism is fixedly connected with a gripper. The adjusting mechanism includes a connecting frame fixedly connected with the connecting plate. A sliding column is fixedly connected inside the connecting frame. The outer surface of the sliding column is slidably connected with multiple groups of limiting mechanisms. One side of the limiting mechanism is fixedly connected with the gripper. The top of the installation arm is fixedly connected with a top plate. A T-shaped sliding groove is opened on one side of the connecting plate. A T-shaped sliding seat is slidably connected to the inner wall of the T-shaped sliding groove. A hydraulic cylinder is hinged between one side of the T-shaped sliding seat and the top plate.

[0007] Preferably, the limiting mechanism includes a limiting frame slidably connected to the outer surface of the sliding column. A through groove is formed on one side of the connecting frame. A threaded hole is formed on the side of the limiting frame facing the through groove. A fixing bolt is threadedly connected inside the threaded hole. A plurality of groups of limiting holes adapted to the fixing bolt are equidistantly formed on the side of the sliding column facing the through groove. The gripper is fixedly connected to one side of the limiting frame.

[0008] Preferably, an installation hole is formed on one side of the gripper. A fixing rod is inserted inside the installation hole. A plurality of groups of locking nuts are threadedly connected to the outer surface of the fixing rod.

[0009] Preferably, a plurality of empty grooves are formed on one side of the connecting plate.

[0010] The beneficial effects of the present utility model are as follows: For a steel grabber for waste metals provided by the present utility model, when using this device, a grab bucket structure can be formed by the grippers on two groups of adjusting mechanisms. The user can start the hydraulic cylinder to grab items with the grippers. If the space for placing waste metals is relatively narrow, the limiting mechanism can be moved to drive the gripper to move, thereby adjusting the length of the entire grab bucket structure to facilitate the grabbing of waste metals. If the waste metals are long or there are a large number of them, the gripper can be added through the installation hole, which can increase the grabbing amount to a certain extent and also make the grabbing of long waste metals more firm, improving the work efficiency to a certain extent.

[0019] As Figure 1 - Figure 6 As shown, a steel grabber for waste metal provided by the present utility model includes a mounting arm 1. Two groups of rotating rods 2 are rotatably connected to one side of the mounting arm 1. A connecting plate 3 is fixedly connected to one side of the rotating rod 2. An adjusting mechanism 4 is fixedly connected to the other side of the connecting plate 3. A grab 5 is fixedly connected to one side of the adjusting mechanism 4. The adjusting mechanism 4 includes a connecting frame 41 fixedly connected to the connecting plate 3. A sliding column 42 is fixedly connected to the inside of the connecting frame 41. The outer surface of the sliding column 42 is slidably connected with multiple groups of limiting mechanisms 43. One side of the limiting mechanism 43 is fixedly connected to the grab 5. A top plate 6 is fixedly connected to the top of the mounting arm 1. A T-shaped sliding groove 8 is formed in one side of the connecting plate 3. A T-shaped sliding seat 9 is slidably connected to the inner wall of the T-shaped sliding groove 8. A hydraulic cylinder 10 is hinged between one side of the T-shaped sliding seat 9 and the top plate 6. When using this device, a grab bucket structure can be formed by the grabs 5 on the two groups of adjusting mechanisms 4. The user can start the hydraulic cylinder 10 to grab an object with the grabs 5. If the space for placing waste metal is relatively narrow, the limiting mechanism 43 can be moved to drive the grab 5 to move, thereby adjusting the length of the entire grab bucket structure to facilitate the grabbing of waste metal.

[0020] The limiting mechanism 43 includes a limiting frame 431 slidably connected to the outer surface of the sliding column 42. A through groove 44 is formed on one side of the connecting frame 41. A threaded hole 432 is formed on the side of the limiting frame 431 facing the through groove 44. A fixing bolt 433 is threadedly connected inside the threaded hole 432. A plurality of groups of limiting holes 45 adapted to the fixing bolt 433 are equidistantly formed on the side of the sliding column 42 facing the through groove 44. The gripper 5 is fixedly connected to one side of the limiting frame 431. The position of the gripper 5 can be adjusted by sliding the limiting frame 431, and then the fixing bolt 433 is rotated to make it snap into the corresponding limiting hole 45, so that the limiting frame 431 stops moving.

[0021] An installation hole 11 is formed on one side of the gripper 5. A fixing rod 12 is inserted inside the installation hole 11. A plurality of groups of locking nuts 13 are threadedly connected to the outer surface of the fixing rod 12. When the waste metal is relatively long or there is a large quantity, the gripper 5 can be added through the installation hole 11, which can increase the grasping quantity to a certain extent, and also make the grasping of the relatively long waste metal more firm, improving the working efficiency to a certain extent.

[0022] A plurality of empty grooves 7 are formed on one side of the connecting plate 3.

[0023] Working principle: When using this device, a grab structure can be formed by the grippers 5 on the two sets of adjusting mechanisms 4. The user can start the hydraulic cylinder 10 to grab an object with the grippers 5. If the space for placing waste metal is relatively narrow, the limiting mechanism 43 can be moved to drive the gripper 5 to move, so as to adjust the length of the entire grab structure, facilitating the grasping of waste metal. When the waste metal is relatively long or there is a large quantity, the gripper 5 can be added through the installation hole 11, which can increase the grasping quantity to a certain extent, and also make the grasping of the relatively long waste metal more firm, improving the working efficiency to a certain extent.
