参阅图1、图2所示,本发明机械缓降器主要包括有主缓降装置和悬挂人体用的吊环两大部分。Referring to Fig. 1 and shown in Fig. 2, the mechanical descending device of the present invention mainly comprises two major parts of main descending device and the suspension ring that hangs the human body usefulness.

所述的主缓降装置由手柄1、壳体2、长承重防火绳索3、绳轮4、连杆5、刹车片6、自行车闸皮副7和一组导向轮8~10组合构成。The main slow-descent device is composed of a handle 1, a housing 2, a long load-bearing fireproof rope 3, a sheave 4, a connecting rod 5, a brake pad 6, a bicycle brake pair 7 and a group of guide wheels 8-10.

所述的壳体2上下开口,横向截面(本实施例中,为图示的主视向截面)呈锥形,壳体的下端一侧壁上开有供手柄1延出的孔。The casing 2 is open up and down, and the transverse section (in this embodiment, the main viewing section shown in the figure) is conical, and a hole for the handle 1 to extend is opened on the side wall of the lower end of the casing.

所述的连杆5,通过连杆轴固定在壳体内中间;连杆的上端固定一闸皮副7(本实施例中采用了自行车闸皮副),下边设有一分支轴。Described connecting rod 5 is fixed in the middle of the housing by the connecting rod shaft; a brake shoe pair 7 is fixed at the upper end of the connecting rod (adopted a bicycle brake shoe pair in the present embodiment), and a branch shaft is provided below.

所述的手柄1右端通过小轴与壳体连接,手柄的左端横向延出壳体外,手柄通过销轴与连杆垂向连接,拉动手柄时以右端小轴为支点转动,连杆同时向下运动。The right end of the handle 1 is connected to the housing through a small shaft, the left end of the handle extends out of the housing laterally, the handle is vertically connected to the connecting rod through a pin shaft, and when the handle is pulled, the small shaft at the right end is used as a fulcrum to rotate, and the connecting rod is downward at the same time sports.

所述的绳轮4,浮动在一对闸皮副7与手柄1之间。The sheave 4 floats between a pair of brake shoe pairs 7 and the handle 1 .

所述的一组导向轮8~10包括一对固定在壳体上端开口处且并排紧靠的导向夹置轮8、9和位于一导向夹置轮下面的一迂回导向轮10。The set of guide wheels 8-10 includes a pair of guide interposition wheels 8, 9 fixed on the opening of the upper end of the housing and adjacent to each other side by side, and a detour guide wheel 10 located below one guide interposition wheel.

所述的长承重防火绳索3向上围绕过绳轮4,一端由上述的一对导向夹置轮8、9间拉出,另一端经迂回导向轮10导出,靠绳的自重而下垂。Described long load-bearing fireproof rope 3 upwards around rope sheave 4, and one end is pulled out between above-mentioned pair of guiding clamping wheels 8,9, and the other end is exported through detour guiding wheel 10, hangs down by the deadweight of rope.

本发明还设计在绳轮的两侧壳体上设有刹车片6。The present invention is also designed to be provided with brake pads 6 on both sides of the sheave.

本发明机械缓降器在主缓降装置的壳体下方固定安装一用于悬挂人体的吊环11,可以通过吊环轴固定在壳体壁上,吊环呈U型为佳。The mechanical descending device of the present invention is fixedly installed a suspension ring 11 for hanging the human body below the housing of the main slow descent device, which can be fixed on the housing wall by the suspension ring shaft, and the suspension ring is U-shaped for better.

在图1中,当发生火灾等突发灾害时,人可将绳的一端栓在室内的固定物(如暖气管、床腿等)上,穿上另备设的安全背带,用安全背带上的挂钩将自己挂于缓降器的U形吊环11上,从窗口爬出。此时手柄1处于水平位置,即人尚未对其施加外力。在人的自重的作用下,绳轮4向锥形壳体2小端运动,通过与两斜面上的刹车片6的作用,挤压楔紧承重防火绳索3,产生了很大的摩擦力,从而阻止绳轮4转动,实现缓降器的自锁功能。此功能保证操作者对缓降器不施加外力时,机械缓降器不会沿承重防火绳索3下降,从而保证人的安全。In Fig. 1, when sudden disasters such as fires occur, people can tie one end of the rope to indoor fixtures (such as heating pipes, bed legs, etc.), put on the safety straps that are equipped separately, and use the safety straps The hook hangs itself on the U-shaped suspension ring 11 of the descender, and climbs out from the window. At this time, the handle 1 is in a horizontal position, that is, no external force has been applied to it by people. Under the action of the person's own weight, the sheave 4 moves toward the small end of the conical shell 2, and through the action of the brake pads 6 on the two slopes, squeezes and wedges the load-bearing fireproof rope 3 tightly, resulting in a large frictional force. Thereby stop rope wheel 4 from rotating, realize the self-locking function of slow descender. This function ensures that when the operator does not apply external force to the descending device, the mechanical descending device will not descend along the load-bearing fireproof rope 3, thereby ensuring the safety of people.

当人用力向下拉动手柄1时,手柄1通过连杆轴带动连杆5向下运动,通过闸皮副7使绳轮4受到向下的作用力,使得绳轮4向下运动,即向着锥形壳体2的大端方向运动,与壳体2及刹车片6间对承重防火绳索3的楔紧压力下降,摩擦力减小,使得绳轮4可以正常转动,缓降器沿承重防火绳索3以一定的加速度下降,即完成下降的功能。此时调节人对手柄1作用力的大小,就可以调整下降的速度。When a person pulls the handle 1 downward with force, the handle 1 drives the connecting rod 5 to move downward through the connecting rod shaft, and the sheave 4 is subjected to a downward force through the brake pair 7, so that the sheave 4 moves downward, that is, toward the The large end of the conical shell 2 moves in the direction, and the wedging pressure between the shell 2 and the brake pad 6 on the load-bearing fireproof rope 3 decreases, and the friction force decreases, so that the rope wheel 4 can rotate normally, and the slow descender moves along the load-bearing fireproof rope 3. Rope 3 descends with certain acceleration, promptly finishes the function of descending. Now adjust the size of people's force on the handle 1, and the speed of descent can be adjusted.

本发明机械缓降器的的结构设计是考虑了人体不能承受很大的速度和加速度的缘由,所以这种装置应具备减速和停止的功能,即下降速度可控。为使装置简单且方便使用,并保证安全,则设计该装置具有上述的自锁功能,通过摩擦力实现自锁。The structural design of the mechanical descending device of the present invention takes into account the reason that the human body cannot withstand large speeds and accelerations, so this device should have the functions of deceleration and stopping, that is, the descending speed is controllable. In order to make the device simple and convenient to use, and to ensure safety, the device is designed to have the above-mentioned self-locking function, and self-locking is realized by friction.

缓降器下降速度的控制,是通过自行车闸皮副7对绳轮4的作用实现的。当人用力向下拉动手柄1时,手柄1带动连杆5向下运动,连杆5带动自行车闸皮副7同时向下运动,此时自行车闸皮副7向下压浮动绳轮4,使得转动的绳轮4受到一定的摩擦力的作用,从而阻碍了绳轮4的转动,绳轮4转动速度降低,从而降低了缓降器的下降速度。由此可以控制缓降器沿着一定的速度均匀下降。The control of the descending speed of the slow descending device is realized by the effect of the bicycle brake leather pair 7 on the rope wheel 4. When a person pulls the handle 1 downwards, the handle 1 drives the connecting rod 5 to move downward, and the connecting rod 5 drives the bicycle brake pair 7 to move downward at the same time. At this time, the bicycle brake pair 7 presses down on the floating rope wheel 4, so that The rotating sheave 4 is subjected to certain frictional force, thereby hindering the rotation of the sheave 4, and the speed of rotation of the sheave 4 is reduced, thereby reducing the descending speed of the slow descender. Thereby, the descender can be controlled to descend evenly along a certain speed.

在下降过程中,当出现紧急情况时,或是因心情紧张惊慌失措而松开了手柄1,缓降器可实现自锁,停止下降,因此人就不会发生意外坠落。所以缓降器起到了安全保护的作用。During the descent, when there is an emergency, or the handle 1 is released due to nervousness and panic, the descending device can realize self-locking and stop descending, so people will not accidentally fall. Therefore, the descending device plays the role of safety protection.

本发明机械缓降器的工作原理及过程是:当机械缓降器处于非工作状态时,即人没有通过安全背带悬挂于U型吊环11上,此时手柄1处于水平位置,绳轮4浮动在闸皮副与手柄1之间,承重防火绳索可以自由运动。图1中,当发生火灾等突发灾害时,人将自己通过安全背带挂于U形吊环11上,此时绳将受很大的冲击力,从而使得绳轮4往壳体2小端运动,此时挤压承重防火绳索3,防火绳索3上产生了很大的摩擦力,用以阻碍绳轮4往下运动,即完成自锁的功能,此功能可以保证在不施加外力时,机械缓降器不会沿承重防火绳索3下降。The working principle and process of the mechanical descending device of the present invention are as follows: when the mechanical descending device is in a non-working state, that is, the person is not suspended on the U-shaped ring 11 through the safety strap, at this time the handle 1 is in a horizontal position, and the rope wheel 4 is floating Between the brake leather pair and the handle 1, the load-bearing fireproof rope can move freely. In Fig. 1, when a sudden disaster such as a fire occurs, the person hangs himself on the U-shaped suspension ring 11 through the safety strap, and the rope will be subjected to a large impact force at this time, so that the rope wheel 4 moves toward the small end of the housing 2 At this time, the load-bearing fireproof rope 3 is squeezed, and a large friction force is generated on the fireproof rope 3 to hinder the downward movement of the rope wheel 4, that is, to complete the self-locking function. This function can ensure that when no external force is applied, the mechanical The descending device can not descend along the load-bearing fireproof rope 3.

当用力向下拉动手柄1时,手柄1带动连杆5向下运动,绳轮4受到向下的作用力,使得绳轮4与壳体2对绳的压力有所下降,从而摩擦力减小,则能保证缓降器沿承重防火绳索3以一定的加速度下降,即完成下降的功能。此时调节人对手柄1作用力的大小,就可以调整下降的速度。When the handle 1 is pulled down with force, the handle 1 drives the connecting rod 5 to move downward, and the sheave 4 receives a downward force, so that the pressure on the rope between the sheave 4 and the casing 2 decreases, thereby reducing the friction , then it can ensure that the descending device descends with a certain acceleration along the load-bearing fireproof rope 3, that is, completes the function of descending. Now adjust the size of people's force on the handle 1, and the speed of descent can be adjusted.

在下降过程中,当出现紧急情况时人手松开手柄1,人和缓降器就因自锁而停止下降,起到安全保护的作用。During the descent, when an emergency occurs, the hand releases the handle 1, and the descending device stops due to self-locking, which plays the role of safety protection.

上述各实施例可在不脱离本发明的范围下加以若干变化,故以上的说明所包含及附图中所示的结构应视为例示性,而非用以限制本发明申请专利的保护范围。The above-mentioned embodiments can be changed without departing from the scope of the present invention, so the structures included in the above description and shown in the drawings should be regarded as illustrative rather than limiting the protection scope of the patent application of the present invention.
