[0031] This application provides an emergency escape system and a gear system for an emergency escape device. Using parallel shaft transmission combined with centrifugal intermittent impact speed control technology, the device employs purely mechanical transmission to enable it to slide down handrails with slopes of 28° to 35°, unaffected by dust, water, oil, and other factors, at a constant speed of 0.8m / s to 1.2m / s (no electric drive required, suitable for various emergency situations).
[0032] This device can be used in emergency situations such as fire. By sliding down the modified and installed handrail track at a constant speed, it can be completed in about 3 minutes from the 30th floor to the 1st floor. For example, it only takes 180 seconds to slide from the 32nd floor to the 1st floor, thus ensuring both the time requirement for emergency escape and the safety of the escaping objects.
[0033] See also Figure 1 and Figure 4 , Figure 1 It is a schematic diagram of the overall structure of the emergency escape system provided by this application; Figure 4 This is a schematic diagram of the overall installation structure of the emergency escape system provided in this application when in use.
[0034] An emergency escape system 100 provided in one embodiment of the present application may include an emergency escape device 2 and a handrail 1. The emergency escape device 2 includes the handrail 1, which may be any of the following handrails; the handrail 1 is mated and connected to the emergency escape device 2. The handrail 1 may be mounted on a load-bearing frame 14, which is mounted on a wall 15.
[0035] See also Figures 2 to 4 , Figure 2 It is a schematic diagram of the overall structure of the handrail track provided in this application; Figure 3 yes Figure 2 Provided is a schematic diagram of the cross-sectional structure along line AA; Figure 4 This is a schematic diagram of the overall installation structure of the emergency escape system provided in this application when in use.
[0036] like Figures 2 to 4 As shown, in one embodiment provided in the present application, the handrail track 1 may include a first main body portion 10, a second main body portion 11 and a third main body portion 12 connected in sequence, and the first main body portion 10, the second main body portion 11 and the third main body portion 12 cooperate to form a semi-enclosed cavity 13; the cavity 13 accommodates the roller 30 of the emergency escape device 2 so that it can be connected to the third main body portion 12.
[0037] In one embodiment, the roller 30 includes a first end 301 and a second end 302 disposed opposite each other, and a contact portion 303 disposed between the first end 301 and the second end 302. The contact portion 303 is in contact with the handrail track 1. The first end 301 and the second end 302 are disposed on opposite sides of the handrail track 1 in the width direction to limit the connection position of the contact portion 303 with the handrail track 1.
[0038] Specifically, the contact portion 303 contacts the top wall 121 of the handrail track 1, and the first end portion 301 and the second end portion 302 are respectively clamped at opposite ends of the top surface to limit the roller 30 in the width direction of the handrail track 1 and prevent the roller 30 from falling off the handrail track 1. In this embodiment, the contact surface between the contact portion 303 and the top wall 121 of the handrail track 1 is coated with a rubber or polymer material (such as polyurethane) with a high friction coefficient and strong wear resistance, thereby increasing the friction of the contact surface and improving durability. It will be understood that in order for the first end portion 301 and the second end portion 302 to limit the contact portion 303, the dimensions of the first end portion 301 and the second end portion 302 should be set to be larger than the dimensions of the contact portion 303. The specific dimensions can be set as needed and are not limited in this application.
[0039] like Figure 2As shown, in one embodiment, a first bend 101 is provided between the first and second body portions 10, 11, and a second bend 105 is provided between the second and third body portions 11, 12. The first bend 101 has a third bend 103 at one end away from the second body portion 11. The third bend 103 can enhance the gripping feel of the handrail, and the width of the handrail grip can be set to 65 mm to 75 mm. A groove structure 106 is formed on the inner sidewall of the third bend 103 between the second and third body portions 11, 12. The groove structure 106 provides space for the installation and operation of the roller 30 of the emergency escape device 2, allowing the emergency escape device 2 to be connected to the third body portion 12. Specifically, the first end 301 is engaged with the groove structure 106, the contact portion 303 contacts the top wall 121 of the handrail track 1, and the second end 302 is engaged with the outer wall / outer edge of the third body portion 12, thereby ensuring a stable connection between the emergency escape device 2 and the handrail track 1.
[0040] In one embodiment, the inner side wall of the first main body portion 10 has a first protrusion 102, and the first protrusion 102 extends toward the cavity 13; the opposite side walls of the first protrusion 102 and the side walls of the first main body portion 10 form a first groove 1021 and a second groove 1022 relative to each other. The design of the first groove 1021 and the second groove 1022 can, on the one hand, reduce the weight of the overall structure of the handrail rail 1, and on the other hand, there is a gap between the surface of the first protrusion 102 close to the load-bearing frame 14 and the bracket of the load-bearing frame 14. The gap can reserve space for the punching position when the handrail rail 1 is connected to the load-bearing frame 14.
[0041] In one embodiment, a second protrusion 104 is provided between the first main body portion 10 and the second main body portion 11. The second protrusion 104 is spaced apart from the first protrusion 102 and is narrower than the first protrusion 102. Furthermore, a third groove 1041 is formed between the second protrusion 104 and the inner sidewall of the first bent portion 101. The second protrusion 104 and the third groove 1041 allow the load-bearing frame 14 to be embedded in the third groove 1041. The second protrusion 104 and the inner sidewall of the first bent portion 101 form a non-smooth structure 1011 that limits the load-bearing frame 14 in the vertical direction. This improves the stability of the handrail track 1 fixed to the wall 15, the stability of the connection between the handrail track 1 and the load-bearing frame 14, and prevents misalignment of the handrail tracks 1 after docking.
[0042] In one embodiment, the first bent portion 101, corresponding to the inner sidewall at the junction of the first and second main portions 10, 11, protrudes beyond the inner sidewalls of the first and second main portions 10, 11, forming a non-smooth structure 1011 between the sidewall of the second protrusion 104 on the side closest to the first protrusion 102 and the first groove 1021. As described above, the non-smooth structure 1011 and the second protrusion 104 limit the vertical position of the load-bearing frame 14.
[0043] In one embodiment, the third bent portion 103 extends toward the cavity 13, and the height of the third bent portion 103 is substantially flush with the height of the first protrusion 102, so that when the handrail track 1 is connected to the load-bearing frame 14, the third bent portion 103 can be close to the outer wall of the load-bearing frame 14 or substantially in contact with the outer wall of the load-bearing frame 14.
[0044] In one embodiment, the third main body portion 12 is arranged at an end of the second main body portion 11 away from the first main body portion 10, and the third main body portion 12 includes a top wall 121, a bottom wall and a partition. The setting position of the top wall 121 is higher than the inner bottom surface of the groove structure 106, so that the groove structure 106 can be formed to facilitate matching and connection with the emergency escape device 2. The specific technical effects of the groove structure 106 can refer to the above content and will not be repeated here. The setting position of the bottom wall is lower than the outer bottom surface of the groove structure 106; the partition is arranged between the top wall 121 and the bottom wall to divide the third main body portion 12 into multiple parts. The setting of the partition can support and reinforce the third main body portion 12 from the inside, thereby improving the stability of the third main body portion 12.
[0045] In one embodiment, the first main body portion 10 , the second main body portion 11 and the third main body portion 12 are an integrally formed structure. The integrally formed structure can make the overall stability of the handrail track 1 stronger and improve its durability.
[0046] In another embodiment, the first body portion 10, the second body portion 11, and the third body portion 12 can be welded sequentially to form an integral structure. Specifically, the first body portion 10, the second body portion 11, and the third body portion 12 can be prepared separately and then welded together to form an integral structure. Welding to form an integral structure has the advantage of convenient production. At the same time, the production processes of the first body portion 10, the second body portion 11, and the third body portion 12 can be carried out simultaneously, thereby improving product production efficiency.
[0047] It should be noted that the above two preparation processes for the first main body 10 , the second main body 11 and the third main body 12 can be selected as needed, and this application does not impose any restrictions on this.
[0048] In addition, the overall structure and appearance of the handrail track 1 provided by the present application are similar to those of existing stair handrails, and it also has the functions of ordinary handrails, and can completely replace the basic functions of existing stair handrails. After installing the handrail track 1 of the present application to replace the existing stair handrail, it can be used as an ordinary handrail in daily life. In the event of an emergency escape (such as a fire or earthquake), the handrail track 1 of the present application can be matched and connected with the emergency escape device 2 to serve as a supporting facility for emergency escape and rescue, thereby ensuring the safety of the user. Therefore, the handrail track 1 of the present application is easy to install and use, while also being low-cost and having a high safety factor.
[0049] The handrail track 1 disclosed in the present application is used for an emergency escape device 2, comprising: a first main body 10, a second main body 11, and a third main body 12 connected in sequence, wherein the first main body 10, the second main body 11, and the third main body 12 cooperate to form a semi-enclosed concave cavity 13; wherein a first bend portion 101 is provided between the first main body 10 and the second main body 11, a second bend portion 105 is provided between the second main body 11 and the third main body 12, and a third bend portion 103 is provided at one end of the first bend portion 101 away from the second main body 11; wherein a groove structure 106 is formed on the inner side wall of the third bend portion 103 between the second main body 11 and the third main body 12, and the emergency escape device 2 is cooperatively connected to the third main body 12. The present application designs the structure of the handrail track 1 to make it safer and more stable in connection with the emergency escape device 2.
[0050] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
