Description

Technical Field

[0001] This utility model relates to the field of demolition support technology, and in particular to a demolition support for confined spaces. Background Technology

[0002] Fire and rescue refers to a series of emergency rescue activities carried out by specialized fire and rescue teams, including fire fighting, search and rescue, natural disaster response, and handling of other emergencies. Fire and rescue teams not only play a key role in fire fighting, but also play an important role in various natural disasters and emergency rescue missions.

[0003] However, in demolition and rescue operations, the narrow space of the pipes, the enclosed nature of the site, and the heavy demolition equipment generally only allow one person to work at a time. Workers can only work in a cramped position, and larger demolition tools are not easy to enter. If a successful rescue cannot be achieved for a long time, it can easily lead to oxygen deprivation, carbon monoxide poisoning, and psychological panic for both rescuers and trapped individuals, resulting in casualties.

[0004] Therefore, those skilled in the art have provided a confined space demolition support to solve the problems mentioned in the background art. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Reference Figure 1-4 An embodiment of this utility model provides a confined space demolition support, including a load-bearing plate 3, a fastener connection 2, and a positioning adjustment button 10. Support arms 1 are fixedly installed on both sides of the load-bearing plate 3 and the fastener connection 2 by threads. Connecting sleeves 11 are slidably installed inside the multiple support arms 1. An installation block 15 is fixedly installed on the front side of the load-bearing plate 3. A directional pulley 6 is fixedly installed on the front side of the installation block 15 by threads. A hand crank 5 is fixedly installed on the upper part of the rear end of one of the multiple support arms 1 by threads. The hand crank 5 can be rotated by hand. A gear body 20 is fixedly installed at the lower end of the outer surface of the hand crank 5. A gravity flat belt 7 is wound and fixedly installed on the middle part of the outer surface of the hand crank 5. A fixing plate 16 is fixedly installed at the middle part of the upper part of the rear end of one of the multiple support arms 1. A spring rod 17 is fixedly installed on the rear side of the fixing plate 16. A gear locking pin 22 is fixedly installed on the rear side of the spring rod 17. A lighting lamp 23 is fixedly installed on the inner side of one of the multiple support arms 1.

[0025] Specifically, the load-bearing plate 3 facilitates the installation of the directional pulley 6 and the threaded installation of the bracket arm 1 with the fastener connection 2 and the positioning adjustment button 10. The bracket arm 1 provides support and is also suitable for use with the connecting sleeve 11, allowing for adjustment according to the width. There are three adjustable positions. The directional pulley 6 assists in the sliding of the gravity flat belt 7 and helps prevent large positional deviations during sliding. The hand crank 5 allows for manual adjustment of the gravity flat belt 7 via the hand crank handle 14. The gear body 20 is suitable for use with the gear locking pin 22 to lock the hand crank 5. The gravity flat belt 7 is suitable for use with the snap hook 8 and snap hook 9 to fix the demolition tools. The fixing plate 16 helps fix the spring rod 17, which in turn drives the gear locking pin 22 to lock the gear body 20, thus limiting the position of the hand crank 5. The lighting lamp 23 provides illumination of the inside of the pipe.

[0026] Multiple support arms 1 have sliding grooves 18 on the upper two sides of one of the rear ends of one of them. A first baffle 19 is slidably installed inside the two sliding grooves 18. Two mouth-shaped buckles 8 are fixedly installed at the lower middle position of the front side of the gravity flat belt 7. A mouth-shaped hook 9 is fixedly installed at the lower end of the gravity flat belt 7. Multiple connecting sleeves 11 have multiple limiting holes 12 on their opposite outer sides. A limiting pin 13 is installed in the internal thread of one of the multiple limiting holes 12. Two fasteners 2 are fixedly connected to the connecting sleeves 11 by threads. A tensioning fastener 4 is threaded in the middle of the two fasteners 2. A hand crank 14 is fixedly installed at the middle position of the upper end of the hand crank 5. Second baffles 21 are fixedly installed on both sides of the gear locking pin 22.

[0027] Specifically, the slide groove 18 facilitates the sliding of the first baffle 19 inside, and the contact between the first baffle 19 and the second baffle 21 limits the position of the gear locking pin 22. The limiting hole 12 facilitates the adjustment of the length of the connecting sleeve 11 with the limiting pin 13. The tension fixing device 4 helps to fix the bracket to the inner wall of the underground well. The hand crank 14 facilitates manual cranking of the hand crank 5. When the demolition tool slides down, the gear locking pin 22 is pressed down, and then the two first baffles 19 are slid to the inside of the slide groove 18. The contact between the first baffle 19 and the second baffle 21 locks the position of the gear locking pin 22. Then, the hand crank 5 is manually rotated. When the desired position is reached, the two first baffles 19 are slid to one side, and the spring rod 17 drives the gear locking pin 22 to lock the gear body 20 and lock the hand crank 5.

[0028] Working principle: When using this device, remove the limiting pin 13 from the limiting hole 12, then adjust the length of the connecting sleeve 11 according to the width of the underground well. After adjustment, fix the positioning adjustment button 10 with threads. Then fix the hand crank 5 to the support arm 1 with threads, and fix the directional pulley 6 to the mounting block 15 with screws. Then select the appropriate gravity flat strap 7 according to the depth of the underground well and install it on the hand crank 5 and the directional pulley 6. Then install the gravity flat strap 7 on the demolition tool, such as a rock drill, through the mouth buckle 8 and mouth hook 9. This makes it easier for the tool to enter the underground pipe and reduces the effort required by firefighters. It is easy to use. Then turn on the lighting lamp 23 for illumination.

[0029] Next, all the installed brackets are fixed to the inner wall of the well using the tension fastener 4. After installation, when the demolition tool slides down, the gear locking pin 22 is pressed down, and then the two No. 1 baffles 19 are slid into the inner side of the slide groove 18. The position of the gear locking pin 22 is limited by the contact between the No. 1 baffle 19 and the No. 2 baffle 21. Then, the hand crank 5 is manually rotated. When the desired position is reached, the two No. 1 baffles 19 are slid to one side, and the spring rod 17 drives the gear locking pin 22 to lock the gear body 20 and lock the hand crank 5.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
