Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, specifically to a throwing cage system. Background Technology

[0002] Throwing cages are protective devices installed around the throwing area of ​​a stadium. Their purpose is to prevent athletes from dropping their equipment or throwing it in the wrong direction, which could cause unnecessary accidental injury to spectators or referees. Existing throwing cages are generally composed of netting, uprights, and cage doors. Existing throwing cages have the following disadvantages: (1) Because the plastic surface of the stadium is easily damaged by lifting equipment, heavy lifting equipment is not allowed to enter the stadium. As a result, the assembly of the throwing cage can only be done manually. The uprights and cage doors are pushed up and erected by hand. However, because the uprights and cage doors are heavy and tall, reaching a height of 7-10 meters, each upright and cage door requires more than a dozen people to push it up and erect it, which is extremely dangerous; (2) The uprights are installed on the stadium by inserting their lower sections directly into the stadium. When the uprights are repaired, a lot of manpower and time are required to pull them out, making disassembly and repair very inconvenient. Summary of the Invention

The throwing cage includes: several embedded parts 1 pre-embedded in the perimeter of the throwing area; a cage column base 2 is inserted into each embedded part 1; a cage column 3 is set on the top of each cage column base 2; each cage column 3 is positioned on the corresponding cage column base 2 by a detachable hinged positioning part 4; a cable guide wheel 33 and a wire sleeve 5 are provided on the upper part of each cage column 3; a tensioner 7 with a steel wire rope 6 wound inside is installed on the lower part of each cage column 3; an upper mesh support pipe 8 is provided between the upper parts of each pair of adjacent cage columns 3; the steel wire rope 6 of the tensioner 7 on each pair of adjacent cage columns 3 passes upward through the corresponding wire sleeve 5 and is connected to the two ends of the corresponding upper mesh support pipe 8, so that the upper mesh support pipe 8 is suspended between the upper parts of the corresponding two cage columns 3. A bottom mesh bracket 9 is installed between the lower parts of the cage uprights 3. In this embodiment, the specific connection structure of the bottom mesh bracket 9 between the two cage uprights 3 includes: a bottom diagonal support bracket 28 is installed at each end of the bottom mesh bracket 9, and a second clamp 29 that can be installed on the cage upright 3 is provided at the outer end of each bottom diagonal support bracket 28. In this way, the bottom mesh bracket 9 can not only be installed on the cage upright 3 by the second clamp, but also the height of the bottom diagonal support bracket 28 can be adjusted synchronously by moving the second clamp 29 along the cage upright 3; a mesh sheet 34 is connected between the corresponding upper mesh support tube 8 and the bottom mesh bracket 9 between each two adjacent cage uprights 3. In actual operation, the height of the upper mesh support tube 8 can be adjusted by winding or unwinding the wire rope with a tensioner, and the height of the bottom diagonal support bracket 28 can be adjusted synchronously by moving the second clamp 29 along the cage upright 3, thereby adjusting the height of the mesh sheet 34.

[0033] Each cage support post 3, each upper net support pipe 8, each bottom net hanging frame 9, and each net panel 34 together form a U-shaped cage frame surrounding the throwing area. A cage door 10 is provided at the opening of the U-shaped cage frame for opening and closing. In this embodiment, there are two cage doors 10, each installed on a cage support post 3 on either side of the opening of the U-shaped cage frame. Each cage door 10 is also equipped with a net panel 34. The inner side of each cage door 10 is hinged to the corresponding cage column 3 at the opening of the U-shaped cage frame via a door hinge 11. A cable guide wheel 33 and a wire sleeve 5 are provided on the upper part of the outer door column 12 of each cage door 10, and a tensioner 7 with a steel wire rope 6 wound inside is provided on the lower part. A wheel frame 13 is provided on the bottom tube of the cage door 10, and wheels 14 for supporting the cage door 10 are installed at the bottom of the wheel frame 13. In this embodiment, the wheel frame 13... The specific connection structure between the cage door 10 and the cage door 10 includes: a connecting plate 30 and two U-shaped locking rods 31. The connecting plate 30 is horizontally installed on the wheel frame 13 and located above the bottom tube 101 of the cage door. The openings of the two U-shaped locking rods 31 face upward and are fastened to the bottom tube 101 of the cage door, and both pass upward through the connecting plate 30. Each U-shaped locking rod 31 is threaded with a locking nut 32 after passing through the connecting plate 30. When the locking nuts 32 are loosened, the cage door 10 can rotate relative to the wheel frame 13. In actual use, during the process of the cage door flipping from a tilted position to an upright position, the cage door 10 is in a state that can rotate relative to the wheel frame 13. Thus, during the process of the cage door flipping from a tilted position to an upright position, the wheel frame 13 will not only not hinder the cage door 10 from flipping up, but will also always provide effective support for the cage door 10. When the locking nuts 32 are tightened, the cage door 10 is fixed together with the wheel frame.

[0034] The cage lifting and lowering mechanism includes: a plurality of lifting and lowering transition wheel assemblies 15 and a plurality of auxiliary lifting and lowering assemblies 16. The lifting and lowering transition wheel assembly includes: a transition wheel bracket 151, on which a transition wheel 152 is supported, and a first clamp 153 is provided on the transition wheel bracket 151 for fixing the transition wheel bracket 151 to the cage column 3 or the gate column 12. The auxiliary lifting and lowering assembly includes: an auxiliary lifting and lowering column 161 that can be installed on the cage column base 2 in the embedded part 1, and a tensioner 7 with a steel wire rope 6 wound inside is provided on the auxiliary lifting and lowering column 161.

[0035] In this embodiment, the structure of the detachable hinged positioning component includes: a first flange plate 17 horizontally fixed at the top of the cage column base 2, wherein each flange hole of the first flange plate 17 is a threaded hole; two first positioning pins 18 are coaxially spaced at one side edge of the first flange plate 17; a second flange plate 19 horizontally installed at the bottom of the cage column 3, wherein each flange hole of the second flange plate 19 is a smooth hole; and a second positioning pin 20 is provided at one side edge of the second flange plate 19. When the second positioning pin 20 on the second flange plate 19 of the cage column 3 is engaged... When the second positioning pin 20 is located between the two first positioning pins 18 on the first flange plate 17 of the corresponding cage column base 2, and is coaxial with each of the first positioning pins 18, a first L-shaped locking pin 21 is provided in both the coaxial second positioning pin 20 and each of the first positioning pins 18. At this time, the cage column 3 can be hinged to the cage column base 2 through the first L-shaped locking pin 21. When the cage column 3 is rotated upward and upright around the first L-shaped locking pin 21, the light holes on the second flange plate 19 of the cage column 3 and the cage column base 2 are connected. The threaded holes on the first flange plate 17 correspond one-to-one. A first locking bolt 22 passes through each corresponding open hole and threaded hole. The threaded shaft of each first locking bolt 22 passes downwards through the corresponding open hole and is threaded into the corresponding threaded hole, thereby locking the first flange plate 17 and the second flange plate 19 together, so that the cage column 3 is fixedly installed on the cage column base 2. When disassembling the cage column, simply unscrew the corresponding first locking bolt 22 of the cage column 3 upwards out of the corresponding threaded hole of the cage column base 2, and then pull out the corresponding first locking bolt. The L-shaped locking pin 21 completes the disassembly of the cage column 3. When installing the cage column 3, simply place the second positioning pin tube 20 on the second flange plate 19 of the cage column 3 between the two first positioning pin tubes 18 on the first flange plate 17 of the corresponding cage column base 2, then insert the first L-shaped locking pin 21 into the coaxial second positioning pin tube 20 and each first positioning pin tube 18, and then thread the screw of each first locking bolt 22 downward through the corresponding light hole and thread it into the corresponding threaded hole. This completes the installation of the cage column 3, which is very convenient for disassembly and maintenance.

[0036] In this embodiment, the specific connection structure between the auxiliary lifting and lowering column 161 and the cage column base 2 in the auxiliary lifting and lowering assembly 16 includes: a third flange plate 23 is horizontally installed at the bottom of the auxiliary lifting and lowering column 161, each flange hole of the third flange plate 23 is a smooth hole, and a third positioning pin tube 24 is provided on one side edge of the third flange plate 23. When the third positioning pin tube 24 on the third flange plate 23 of the auxiliary lifting and lowering column 161 is located between two first positioning pin tubes 18 on the first flange plate 17 of the corresponding cage column base 2, and the third positioning pin tube 24 is coaxial with each of the first positioning pin tubes 18, a second L-shaped locking pin 25 is passed through the coaxial third positioning pin tube 24 and each of the first positioning pin tubes 18. The auxiliary lifting column 161 can be hinged to the cage column base 2 via the second L-shaped locking pin 25. When the auxiliary lifting column 161 is rotated upward and upright around the second L-shaped locking pin 25, the holes on the third flange plate 23 of the auxiliary lifting column 161 correspond one-to-one with the threaded holes on the first flange plate 17 of the cage column base 2. A second locking bolt 26 is inserted in each corresponding hole and threaded hole. The screw of each second locking bolt 26 passes downward through the corresponding hole and is threaded into the corresponding threaded hole, thereby locking the first flange plate 17 and the third flange plate 23 together and fixing the auxiliary lifting column 161 to the cage column base 2. The above structure is simple and easy to disassemble and maintain.

[0037] In this embodiment, the specific installation structure of the mesh 34 on the cage door 10 includes: a hanging wire rod 27 is provided on the upper part of the cage door 10; the wire rope 6 in the tensioner 7 on the cage column 3 hinged to the cage door 10 and the wire rope 6 in the tensioner 7 on the door column 12 of the cage door 10 pass upward through the corresponding wire sleeve 5 and are respectively connected to the two ends of the corresponding hanging wire rod 27, so that the hanging wire rod 27 is suspended on the upper part of the cage door 10, and the mesh of the cage door 10 is hung between the hanging wire rod 27 and the wheel frame 13 of the cage door 10. Since the hanging wire rod 27 is suspended in the cage door through the wire rope of each tensioner 7, in actual operation, the height of the hanging wire rod can be adjusted by winding or unwinding the wire rope through the tensioner, thereby adjusting the height of the mesh on the cage door.

[0038] In this embodiment, a connecting mechanism is also provided between the cage door 10 and the wheel frame 13, which can lock and fix the cage door 10 and the wheel frame 13 when the cage door 10 is flipped upright relative to the wheel frame 13. The structure of the connecting mechanism includes: a door brace 35, a connecting pin 36, and a pair of ear plates 37. The pair of ear plates 37 are installed on the top of the wheel frame 13. The upper end of the door brace 35 is hinged to the door post 12 of the cage door 10. The lower end of the door brace 35 is provided with a through hole. When the door 10 is flipped upright relative to the wheel frame 13, the lower end of the door brace 35 is inserted between a pair of ear plates 37, and the through hole of the door brace 35 is coaxial with the ear hole of the pair of ear plates 37. The connecting pin 36 is simultaneously inserted into the corresponding ear hole and through hole, thereby locking and fixing the cage door 10 and the wheel frame 13. In this way, when the cage door is flipped upright, locking and fixing the cage door and the wheel frame can increase the stability of the cage door and thus improve the overall safety of the throwing cage.

[0039] To facilitate the transportation of each cage support column 3 and cage door 10, each cage support column 3 and cage door 10 is initially placed horizontally when transported to the outer perimeter of the stadium throwing area.

[0040] The assembly process of a cage door is as follows:

[0041] First, several embedded parts 1 are pre-embedded in the outer area of ​​the throwing area, and a cage support column base 2 is inserted into each embedded part 1. Then, in a flat state, the cage door 10 is hinged to a cage support column 3 through a door hinge 11. Then, the worker moves the cage door 10, which is hinged to the cage support column 3, to the side of a cage support column base 2 corresponding to the opening of the throwing cage. Then, the cage support column 3 and the cage door 10 are slightly moved, and the second positioning pin tube 20 on the second flange plate 19 of the cage support column 3 is inserted between the two first positioning pin tubes 18 on the first flange plate 17 of the corresponding cage support column base 2, and the second positioning pin tube 20 is coaxial with each of the first positioning pin tubes 18. Then, the first L-shaped locking pin 21 passes through the corresponding second positioning pin tube 20 and each of the first positioning pin tubes 18. At this time, the cage door 10 and the cage support column 3 are hinged to the cage support column base 2 through the first L-shaped locking pin 21.

[0042] Then, an auxiliary lifting and lowering assembly 16 is installed on the base 2 of the two cage pillars opposite the cage door, and a transition wheel assembly 15 is installed on the gate pillar 12 and the cage pillar 3 of the cage door 10. Then, the wire rope 6 in the tensioner 7 of one auxiliary lifting and lowering assembly 16 is passed around the transition wheel 152 in the transition wheel assembly 15 installed on the gate pillar 12 and then connected to the wire rope 6 in the tensioner 7 of the gate pillar 12. The wire rope in the tensioner 7 of the other auxiliary lifting and lowering assembly 16 is passed around the transition wheel 152 in the transition wheel assembly 15 installed on the cage pillar 3 and then connected to the wire rope 6 in the tensioner 7 of the cage pillar 3.

[0043] Next, two workers are positioned at the two auxiliary lifting and lowering components 16 respectively, and simultaneously wind up the wire ropes 6 in the tensioners 7 of the two auxiliary lifting and lowering components 16. At the same time, one worker is positioned at the front of the cage door 10 and lifts the cage door 10 upwards. As the two workers continue to wind up the wire ropes 6 in the tensioners 7 of the two auxiliary lifting and lowering components 16, the cage door 10 and the cage upright 3 will gradually flip upwards relative to the wheel frame 13 until the cage door 10 and the cage upright 3 are flipped upright. Because the second positioning pin tube 20 of the cage upright 3 is located at the two corresponding cage upright bases 2, The first positioning pin 18 is positioned between the first positioning pin 18 and the second positioning pin 20, so the second positioning pin 20 and the first positioning pin 18 can position the cage column 3 and the cage column base 2. When the cage door 10 and the cage column 3 are flipped upright, the holes on the second flange plate 19 of the cage column 3 correspond one-to-one with the threaded holes on the first flange plate 17 of the cage column base 2. Then, a first locking bolt 22 is inserted into each corresponding hole and threaded hole to lock the first flange plate 17 and the second flange plate 19 together so that the cage column 3 is fixedly installed on the cage column base 2.

[0044] Then, insert the lower end of the door brace 35 on the door post 12 between a pair of ear plates 37 of the wheel frame 13, and make the through hole of the door brace 35 coaxial with the ear hole of the pair of ear plates 37. Then, insert the connecting pin 36 into the corresponding ear hole and through hole, thereby locking and fixing the cage door 10 to the wheel frame 13; thus completing the assembly of a cage door.

[0045] The assembly process for the other cage door is as follows:

[0046] First, remove the auxiliary lifting and lowering assembly 16 that has been installed at the opening of the throwing cage from the cage column base 2. Then, another cage door 10 is hinged to another cage column 3 through the door hinge 11. Then, the worker moves the cage door 10, which is hinged to the cage column 3, to the other cage column base 2 corresponding to the opening of the throwing cage. Then, the cage column 3 and the cage door 10 are moved slightly. The second positioning pin tube 20 on the second flange plate 19 of the cage column 3 is inserted between the two first positioning pin tubes 18 on the first flange plate 17 of the cage column base 2, and the second positioning pin tube 20 is coaxial with each of the first positioning pin tubes 18. Then, the first L-shaped locking pin 21 passes through the corresponding second positioning pin tube 20 and each of the first positioning pin tubes 18. At this time, the cage door 10 and the cage column 3 are hinged to the cage column base 2 through the first L-shaped locking pin 21.

[0047] Then, an auxiliary lifting and lowering assembly 16 is installed on the base 2 of the two cage pillars opposite the cage door, and a transition wheel assembly 15 is installed on the gate pillar 12 and the cage pillar 3 of the cage door 10. Then, the wire rope 6 in the tensioner 7 of one auxiliary lifting and lowering assembly 16 is passed around the transition wheel 152 in the transition wheel assembly 15 installed on the gate pillar 12 and then connected to the wire rope 6 in the tensioner 7 of the gate pillar 12. The wire rope in the tensioner 7 of the other auxiliary lifting and lowering assembly 16 is passed around the transition wheel 152 in the transition wheel assembly 15 installed on the cage pillar 3 and then connected to the wire rope 6 in the tensioner 7 of the cage pillar 3.

[0048] Next, two workers are positioned at the two auxiliary lifting and lowering components 16 respectively, and simultaneously wind up the wire ropes 6 in the tensioners 7 of the two auxiliary lifting and lowering components 16. At the same time, one worker is positioned at the front of the cage door 10 and lifts the cage door 10 upwards. As the two workers continue to wind up the wire ropes 6 in the tensioners 7 of the two auxiliary lifting and lowering components 16, the cage door 10 and the cage upright 3 will gradually flip upwards relative to the wheel frame 13 until the cage door 10 and the cage upright 3 are flipped upright. Because the second positioning pin tube 20 of the cage upright 3 is located at the two corresponding cage upright bases 2, The first positioning pin 18 is positioned between the first positioning pin 18 and the second positioning pin 20, so the second positioning pin 20 and the first positioning pin 18 can position the cage column 3 and the cage column base 2. When the cage door 10 and the cage column 3 are flipped upright, the holes on the second flange plate 19 of the cage column 3 correspond one-to-one with the threaded holes on the first flange plate 17 of the cage column base 2. Then, a first locking bolt 22 is inserted into each corresponding hole and threaded hole to lock the first flange plate 17 and the second flange plate 19 together so that the cage column 3 is fixedly installed on the cage column base 2.

[0049] Then, insert the lower end of the door brace 35 on the door post 12 between a pair of ear plates 37 on the wheel frame 13, and make the through hole of the door brace 35 coaxial with the ear hole of the pair of ear plates 37. Then, insert the connecting pin 36 into the corresponding ear hole and through hole to lock the cage door 10 and the wheel frame 13 together; thus completing the assembly of another cage door.

[0050] The assembly process of the cage support posts is as follows:

[0051] In a flat position, the cage column 3 is moved horizontally to a cage column base 2. Then, the cage column 3 is moved slightly, and the second positioning pin 20 on the second flange plate 19 of the cage column 3 is inserted between the two first positioning pins 18 on the first flange plate 17 of the corresponding cage column base 2. The second positioning pin 20 is coaxial with each of the first positioning pins 18. Then, the first L-shaped locking pin 21 passes through the corresponding second positioning pin 20 and each of the first positioning pins 18. At this time, the cage column 3 is hinged to the cage column base 2 through the first L-shaped locking pin 21.

[0052] Then, an auxiliary lifting and lowering assembly 16 is installed on a cage column base 2 on the opposite side of the cage column 3, and a transition wheel assembly 15 is installed on the cage column 3 at the same time; then, the wire rope 6 in the tensioner 7 of the auxiliary lifting and lowering assembly 16 is passed around the transition wheel 152 in the transition wheel assembly 15 installed on the cage column 3 and then connected to the wire rope 6 in the tensioner 7 of the cage column 3.

[0053] Next, one worker winds up the wire rope 6 in the tensioner 7 of the auxiliary lifting assembly 16, while another worker, positioned at the front end of the cage column 3, lifts the cage column 3 upwards. As the workers continuously wind up the wire rope 6 in the tensioner 7 of the auxiliary lifting assembly 16, the cage column 3 gradually flips upwards until it stands upright. Because the second positioning pin 20 of the cage column 3 is located between the two first positioning pins 18 corresponding to the cage column base 2, the second positioning pin 20 and the first positioning pin... Pipe 18 can position the cage column 3 and the cage column base 2. When the cage column 3 is flipped upright, the holes on the second flange plate 19 of the cage column 3 correspond one-to-one with the threaded holes on the first flange plate 17 of the cage column base 2. Then, a first locking bolt 22 is inserted into each corresponding hole and threaded hole to lock the first flange plate 17 and the second flange plate 19 together, so that the cage column 3 is fixedly installed on the cage column base 2, thereby completing the assembly of the cage column.

[0054] The assembly process of the netting for the throwing cage is as follows:

[0055] The steel wire ropes 6 in the tensioners 7 on the two adjacent cage columns 3 are passed upward through the corresponding conductor sleeves 5 and then connected to the two ends of the upper mesh support tube 8. The steel wire ropes in each tensioner 7 are then wound up until the upper mesh support tube 8 is suspended between the upper parts of the two corresponding cage columns 3. The bottom mesh hanger 9 is then installed between the lower parts of the two adjacent cage columns 3 through the second clamp 29. The upper and lower ends of the mesh are then connected to the upper mesh support tube 8 and the bottom mesh hanger 9, thus completing the installation of the mesh.

[0056] The advantages of this invention are: (1) It is safe to assemble the throwing cage. Only 2-3 people are needed to push the uprights and cage doors upright, which greatly saves labor and costs and improves assembly efficiency; (2) It is easy to disassemble and repair the cage uprights and cage doors, which greatly shortens the maintenance time.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any modifications or equivalent changes made based on the technical essence of the present invention shall still fall within the scope of protection claimed by the present invention.
