Description

Technical Field

[0001] This utility model relates to the field of steel structure space frame members technology, and in particular to a bracket device for the rear end of a rust removal and grinding machine for steel structure space frame members. Background Technology

[0002] Steel space frame poles are the basic elements that make up a steel space frame. They are composed of multiple poles (such as top chords, bottom chords, web members, etc.) that are tightly connected by nodes to form a three-dimensional spatial structure with a specific grid pattern. They are used to bear and transfer loads. Steel space frame poles use high-strength steel as the basic material, which has excellent tensile and compressive strength and can withstand large loads to ensure the safety of the building. At the same time, steel is corrosion resistant and durable, which can extend the service life of the building.

[0003] After the steel structure members are processed and assembled, they need to undergo grinding and other processes. After grinding, the steel structure members are prone to rolling off, and it is inconvenient to transport and hoist them after they roll off, which is not conducive to user use. Therefore, we propose a bracket device for the rear end of a rust removal and grinding machine for steel structure space frame members. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bracket device for the rear end of a rust removal and grinding machine for steel structure space frame members, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bracket device for the rear end of a rust removal and grinding machine for steel structure space frame members includes two connecting blocks, which are symmetrically distributed. The top of the two connecting blocks is fixedly connected to two symmetrically distributed shells. The shells are equipped with a moving component inside and a height adjustment component on the top of the shells. A rotating shaft is rotatably connected to one side of each shell, and a transmission component is provided outside the two rotating shafts.

[0007] Preferably, the moving component includes a bidirectional screw fixedly connected to one end of a rotating shaft, one end of which extends into the interior of the housing and is rotatably connected to one side of the inner wall of the housing, and the external thread of the bidirectional screw is connected to two symmetrically distributed threaded sleeves.

[0008] Preferably, the top of the housing is provided with a groove, and the top of the threaded sleeve is fixedly connected to a slider, which is slidably connected inside the groove.

[0009] Preferably, the height adjustment assembly includes a connecting plate fixedly connected to the top of the slider, a threaded sleeve fixedly connected to the top of the connecting plate, and a threaded rod connected to the inside of the threaded sleeve.

[0010] Preferably, the transmission assembly includes synchronous pulleys fixedly sleeved on the outside of two rotating shafts, and the two synchronous pulleys are movably sleeved with the same synchronous belt.

[0011] Preferably, a handle is fixedly connected to the top of the threaded rod, the handle being made of rubber, and a throttle is fixedly connected to one end of one of the timing pulleys, the throttle being made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When it is necessary to adjust the distance between two symmetrical threaded sleeves and threaded rods, first hold the handle and rotate it. By rotating the handle, one of the shafts can be driven to rotate. Through the synchronous pulleys and synchronous belts set on the two shafts, the rotation of one shaft can drive the other shaft to rotate, and then drive the two bidirectional screws to rotate simultaneously. At this time, the two symmetrical threaded sleeves move in opposite directions. When the threaded sleeves move, they drive the slider to slide and connect inside the groove, so that the slider will not rotate when it moves. By moving the slider, the connecting plate, threaded sleeve and threaded rod can be moved. At this time, the two symmetrical threaded sleeves can be adjusted. The distance between the threaded sleeve and the threaded rod is adjustable, allowing for adjustment based on the number of space frame rods requiring support. By gripping and rotating the handle, the threaded rod moves within the threaded sleeve. The height of the adjustable threaded rod can be adjusted to accommodate the height of the space frame rods. This structure significantly reduces the workload of manually collecting and rolling down steel space frame rods during the processing of steel structure space frame members. It also facilitates hoisting and transportation, improving efficiency and demonstrating excellent performance. Furthermore, the adjustable threaded rod and threaded sleeve allow for high adaptability, greatly simplifying operation for workers. Attached Figure Description

[0018] 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.

[0019] Example: Refer to Figure 1-4 A bracket device for the rear end of a rust removal and grinding machine for steel structure space frame members includes two connecting blocks 1, which are symmetrically distributed. The top of the two connecting blocks 1 is fixedly connected to two symmetrically distributed shells 2. The shells 2 are equipped with a moving component inside and a height adjustment component on the top of the shells 2. A rotating shaft 4 is rotatably connected to one side of each of the two shells 2, and a transmission component is provided on the outside of the two rotating shafts 4.

[0020] The mechanism involves rotating the handle 7, which in turn drives two bidirectional screws 3 to rotate simultaneously via the synchronous pulleys 5 and synchronous belts 6 on the two rotating shafts 4. This causes two symmetrical threaded sleeves 8 to move in opposite directions. The movement of the slider 9 then moves the connecting plate 11, threaded sleeve 12, and threaded rod 13. This allows for adjustment of the distance between the two symmetrical threaded sleeves 12 and the threaded rod 13, which can be adjusted according to the number of space frame rods required for the bracket. By gripping and rotating the handle 14, the threaded rod 13 moves within the threaded sleeve 12. The height-adjustable threaded rod 13 allows for adjustment of the height of the space frame rods required for the bracket. This structure significantly reduces the workload of manually collecting and rolling down steel space frame rods during the steel structure space frame rod processing. It also facilitates hoisting and transportation, improving efficiency and providing excellent performance. Furthermore, the threaded rod 13 and threaded sleeve 12 can be adjusted according to the height and number of steel structure space frame rods, offering high adaptability and greatly facilitating use by personnel.

[0021] Furthermore, the movable component includes a bidirectional screw 3 fixedly connected to one end of the rotating shaft 4. One end of the bidirectional screw 3 extends into the interior of the housing 2 and is rotatably connected to one side of the inner wall of the housing 2. The external thread of the bidirectional screw 3 is connected to two symmetrically distributed threaded sleeves 8.

[0022] The distance between the two symmetrical threaded sleeves 12 can be adjusted by using the movable component.

[0023] Furthermore, a groove 10 is provided on the top of the housing 2, and a slider 9 is fixedly connected to the top of the threaded sleeve 8. The slider 9 is slidably connected inside the groove 10.

[0024] By sliding the slider 9 inside the groove 10, the threaded sleeve 8 will not rotate when it moves.

[0025] Furthermore, the height adjustment assembly includes a connecting plate 11 fixedly connected to the top of the slider 9, a threaded sleeve 12 fixedly connected to the top of the connecting plate 11, and a threaded rod 13 threadedly connected to the inside of the threaded sleeve 12.

[0026] The height of the threaded rod 13 can be adjusted by using the height adjustment component.

[0027] Furthermore, the transmission assembly includes timing pulleys 5 fixedly sleeved on the outside of the two rotating shafts 4, and the two timing pulleys 5 are movably sleeved with the same timing belt 6.

[0028] The transmission components allow both shafts 4 to rotate simultaneously.

[0029] Furthermore, a handle 14 is fixedly connected to the top of the threaded rod 13. The handle 14 is made of rubber. One end of one of the timing pulleys 5 is fixedly connected to a throttle 7, which is also made of rubber.

[0030] The rubber grips 14 and 7 are designed to improve the comfort of staff when turning them.

[0031] In use: When it is necessary to adjust the distance between two symmetrical threaded sleeves 12 and threaded rods 13, first hold the handle 7 and turn it. Turning the handle 7 will drive one of the rotating shafts 4 to rotate. Through the synchronous pulleys 5 and synchronous belt 6 mounted on the two rotating shafts 4, the rotation of one rotating shaft 4 will drive the other rotating shaft 4 to rotate, subsequently driving the two bidirectional screws 3 to rotate simultaneously. At this time, the two symmetrical threaded sleeves 8 move in opposite directions. When the threaded sleeves 8 move, they cause the slider 9 to slide and connect inside the groove 10, preventing the slider 9 from rotating during movement. The movement of the slider 9 will drive the connecting plate 11, threaded sleeves 12, and threaded rods 13 to move, thus adjusting the distance between the two symmetrical threaded sleeves 12 and threaded rods 13. The distance between the sleeve 12 and the threaded rod 13 can be adjusted according to the number of space frame rods that need to be supported. By gripping and rotating the handle 14, the threaded rod 13 can be moved inside the threaded sleeve 12. The height-adjustable threaded rod 13 can be adjusted according to the height of the space frame rods that need to be supported. With the above structure, the application of this support in the processing of steel structure space frame rods greatly reduces the workload of manually collecting and rolling steel structure space frame rods, while facilitating hoisting and transportation and improving efficiency. The effect is excellent. At the same time, the threaded rod 13 and the threaded sleeve 12 can be adjusted according to the height and number of steel structure space frame rods, with high adaptability, which greatly facilitates the use of workers.
