Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude rescue descenders, in particular to a high-altitude rescue descender driven by an electric drill. Background Art

[0002] The high altitude rescue descender is an escape device designed to prevent emergencies in buildings. It allows people to slowly descend from high altitude indoors to outdoors along a rope, allowing trapped people to escape quickly. When a fire occurs in a high-rise building and the fire rescue team has not arrived or the ladder is not high enough, the thick smoke and fire block the evacuation passage. The trapped people can use the descender to escape safely and quickly by themselves, changing the passive situation in the past where they could only rely on fire rescue.

[0003] At present, most reciprocating descenders on the market use nylon ropes. When using nylon ropes, the rope drum is large and heavy, and the rope drum must be thrown downstairs when in use. The large size and weight will cause safety hazards, and it is not suitable for people with limited mobility such as the elderly and children, and the descending height is limited.

[0004] For example, a reciprocating high-altitude rescue descender disclosed in Chinese patent CN218356967U uses steel rope instead of traditional nylon rope to increase durability. Moreover, steel rope is thinner than nylon rope, so the same volume can be equipped with longer steel rope, or at the same length, the volume of the steel rope after winding is smaller, the required rope reel is smaller, the weight is lighter, and it is more convenient to store and use for people with less strength. In addition, the steel rope has stronger safety, can increase the maximum descent weight, and expand the scope of use. The steel rope is wound in a semicircular groove to prevent the steel rope and the rope reel from slipping laterally, which increases the safety of use.

[0005] However, it is very inconvenient to raise and lower the rescue descender by pulling the rope by hand.

[0006] For this reason we urgently need to provide a kind of high-altitude rescue descender that utilizes electric drill to drive. Utility Model Content

[0007] The utility model aims to provide a high-altitude rescue descender driven by an electric drill, so as to solve the problem in the above-mentioned background technology that the rescue descender is inconvenient to be raised and lowered by a hand rope.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-altitude rescue descender driven by an electric drill, comprising a shell and a connecting frame, the connecting frame being connected to the front end of the shell, the inner and outer ends of the shell and the connecting frame being connected with a driving mechanism, the driving mechanism comprising a driving unit and a disassembly unit, the driving unit being arranged at the inner and outer ends of the shell and the connecting frame, the disassembly unit being arranged at the outer ends of the shell and the connecting frame.

[0009] The driving unit includes a first bearing, a first circular shaft, a hexagonal socket, a handwheel, a driving gear, a second bearing, a second circular shaft, a driven gear, a winding wheel, a clamping wheel, a rope clamp and a rescue rope. The first bearing is fixedly connected to the upper left end of the inner side of the connecting frame, the first circular shaft is fixedly connected to the inner side of the first bearing, the hexagonal socket is fixedly connected to the front end of the first circular shaft, the handwheel is fixedly connected to the outer side of the front end of the hexagonal socket, the driving gear is fixedly connected to the middle position of the outer side of the first circular shaft, the second bearing is fixedly connected to the upper left end of the inner side of the connecting frame, the second circular shaft is fixedly connected to the inner side of the second bearing, the driven gear is fixedly connected to the outer side of the front end of the second circular shaft, the winding wheel is fixedly connected to the outer side of the rear end of the second circular shaft, the clamping wheel is rotatably connected to the left and right ends of the inner rear of the shell, the rope clamp is fixedly connected to the upper left end of the outer side of the shell, and the rescue rope is sleeved on the outer end of the winding wheel.

[0010] A further improvement is that the outer side of the clamping wheel abuts against the outer side of the rescue rope, so that the rescue rope can rotate along with the rotation of the winding wheel and will not fall off the outer end of the winding wheel.

[0011] A further improvement is that the driving gear and the driven gear are meshed. Thus, after the drill bit of the electric drill is inserted into the inner side of the hexagon socket, the electric drill is turned on to drive the hexagon socket and the first circular shaft to rotate, so that the driving gear at the outer end rotates, which can drive the driven gear to rotate, so that the second circular shaft rotates and drives the winding wheel to rotate, thereby driving the rescue rope at the outer end to rotate together to achieve the lifting of the hoisted object.

[0012] A further improvement is that the disassembly and assembly unit includes a front connecting plate, a rear connecting plate, a spring, a baffle and a rectangular sleeve, the front connecting plate is fixedly connected to the middle position of the left and right ends of the connecting frame, the rear connecting plate is fixedly connected to the middle position of the left and right ends of the front outer side of the shell, the spring is connected to the inner front end of the rear connecting plate, and the baffle is fixedly connected to the left end of the spring.

[0013] A further improvement is that a rectangular groove is provided at the left side of the front end of the rear connecting plate, the right end of the spring is fixedly connected to the right end of the inner side of the rectangular groove, and the outer side of the baffle is slidably connected to the inner side of the rectangular groove. Therefore, when the spring is elastically driven to move the baffle, it can only slide along the inner side of the rectangular groove, thereby limiting the movement of the baffle.

[0014] A further improvement is that the rear side of the front connecting plate abuts against the front side of the rear connecting plate, the outer sides of the front connecting plate and the rear connecting plate are slidably connected to the inner side of the rectangular sleeve, the side of the rectangular sleeve close to the center of the shell abuts against the outer side of the shell, and the side of the rectangular sleeve away from the shell abuts against the side of the baffle close to the shell. Thus, after the shell is placed on the rear side of the connection frame and the rear connecting plate contacts the front connecting plate, the rectangular sleeve is slid to the outer sides of the front connecting plate and the rear connecting plate, and then the spring rebounds to push the baffle to slide out of the rectangular groove to the outer side of the rectangular sleeve, so that the front connecting plate and the rear connecting plate are fixed to the inner side of the rectangular sleeve, and the shell is fixed to the rear side of the connection frame.

[0015] A further improvement is that the inner side of the rope clamp is slidably connected to the outer side of the rescue rope, so that when the rescue rope descends, friction is generated by passing the rescue rope through the inner side of the rope clamp, so that the descending speed of the rescue rope is slowed down.

[0016] In summary, the present application discloses a high-altitude rescue descender driven by an electric drill.

[0017] According to the technical solution, after the drill bit of the electric drill is inserted into the inner side of the hexagonal socket, the electric drill is turned on to drive the hexagonal socket and the first circular shaft to rotate, so that the driving gear at the outer end rotates, which can drive the driven gear to rotate, so that the second circular shaft rotates and drives the winding wheel to rotate, thereby driving the rescue rope at the outer end to rotate together to realize the lifting and lowering of the hoisted object, so there is no need to manually pull the rescue rope for lifting and lowering, which is very convenient.

[0018] Furthermore, after the outer shell is placed on the rear side of the connecting frame and the rear connecting plate contacts the front connecting plate, the rectangular sleeve is slid to the outside of the front connecting plate and the rear connecting plate, and then the spring rebound pushes the baffle to slide out of the rectangular groove to the outside of the rectangular sleeve, so that the front connecting plate and the rear connecting plate are fixed to the inner side of the rectangular sleeve, thereby fixing the outer shell to the rear side of the connecting frame, so that the main body of the descent control device can be disassembled and assembled very conveniently through the disassembly and assembly unit, so as to facilitate the inspection and maintenance of the interior of the descent control device.

[0027] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0028] Embodiment 1:

[0029] A high-altitude rescue descender driven by an electric drill comprises a shell 1 and a connecting frame 2, wherein the connecting frame 2 is connected to the front end of the shell 1, and a driving mechanism is connected to the inner and outer ends of the shell 1 and the connecting frame 2. The driving mechanism comprises a driving unit and a disassembly unit. The driving unit is arranged at the inner and outer ends of the shell 1 and the connecting frame 2, and the disassembly unit is arranged at the outer ends of the shell 1 and the connecting frame 2.

[0030] The driving unit includes a first bearing 301, a first circular shaft 302, a hexagon socket 303, a hand wheel 304, a driving gear 305, a second bearing 306, a second circular shaft 307, a driven gear 308, a winding wheel 309, a clamping wheel 310, a rope clamp 311 and a rescue rope 312.

On the side, the driving gear 305 is fixedly connected to the middle position of the outer side of the first circular shaft 302, the second bearing 306 is fixedly connected to the upper left end of the inner part of the connection frame 2, the second circular shaft 307 is fixedly connected to the inner side of the second bearing 306, the driven gear 308 is fixedly connected to the outer side of the front end of the second circular shaft 307, the winding wheel 309 is fixedly connected to the outer side of the rear end of the second circular shaft 307, the clamping wheel 310 is rotatably connected to the left and right ends of the inner rear of the housing 1, the rope clamp 311 is fixedly connected to the upper left end of the outer side of the housing 1, and the rescue rope 312 is sleeved on the outer end of the winding wheel 309. The outer side of the clamping wheel 310 abuts against the outer side of the rescue rope 312. Therefore, the rescue rope 312 can rotate together with the rotation of the winding wheel 309 and will not fall off from the outer end of the winding wheel 309.

[0031] The driving gear 305 is meshed with the driven gear 308. After the drill bit of the electric drill is inserted into the inner side of the hexagon socket 303, the electric drill is turned on to drive the hexagon socket 303 and the first circular shaft 302 to rotate, so that the driving gear 305 at the outer end rotates, which can drive the driven gear 308 to rotate, so that the second circular shaft 307 rotates and drives the winding wheel 309 to rotate, thereby driving the rescue rope 312 at the outer end to rotate together to achieve the lifting of the hoisted object.

[0032] Embodiment 2:

[0033] On the basis of the first embodiment: the disassembly unit includes a front connecting plate 701, a rear connecting plate 702, a spring 703, a baffle 704 and a rectangular sleeve 705, the front connecting plate 701 is fixedly connected to the middle position of the left and right ends of the connecting frame 2, the rear connecting plate 702 is fixedly connected to the middle position of the left and right ends of the outer front of the housing 1, the spring 703 is connected to the inner front end of the rear connecting plate 702, and the baffle 704 is fixedly connected to the left end of the spring 703.
