Description

Technical Field

[0001] The invention relates to the technical field of high-altitude manned passage, and specifically to a three-in-one ladder track capable of supporting a climbing device in various environmental working conditions and a use method thereof. Background Art

[0002] In our daily work, we need to pass through high-risk working conditions, especially in high-risk environments such as vertical climbing, slope passage or multiple working conditions. People frequently climb and pass through this environment, and there is a risk of falling from heights. In order to ensure the safety of climbing personnel, it is generally mandatory for passing personnel to take effective protective measures before they can pass through such environmental conditions. For example, during equipment maintenance, it is necessary to pass through such environments frequently every day, which places high demands on the physical fitness of passing personnel. In today's modern world, in order to effectively ensure the safety of workers, and reduce the excessive physical energy consumed by workers during the climbing process, sufficient physical strength is reserved for subsequent operations, and ensure that on-site operations can be carried out safely and efficiently, climbing devices are generally used to carry passing personnel. However, if the equipment fails, how to quickly evacuate the site is an urgent problem for our managers to solve.

[0003] At present, in order to ensure the safety of the upper and lower passages, a special ladder for people to climb is generally installed in the passage, so that when the climbing device fails, people can use the special ladder for emergency evacuation. However, this method has the following problems: 1. When the climbing equipment fails during operation, passengers cannot evacuate in time, while the rest of the passengers can evacuate in an orderly manner through the dedicated ladder, which fails to solve the actual problem; Second, the layout of the climbing device system and the special ladder system requires a large space, but the actual situation on site often does not have such a large space to install two systems, resulting in the inability to effectively implement the special ladder solution, and thus unable to ensure that personnel can quickly evacuate the site in the event of a climbing device failure; 3. The price cost is high. The special ladder set up to meet the needs of rapid evacuation of personnel has a very high manufacturing and installation cost, and the effective utilization rate of the special ladder installed separately is low, and its cost performance is very low. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a three-in-one ladder track and a method of use that can support a climbing device in a variety of environmental conditions, so that when a climbing device fails to operate in a complex and dangerous environment, personnel can quickly evacuate the fault site on their own, thereby protecting the life and health of the operators. The system device has a simple structure, light weight, and is easy and quick to use. The guide rail can be set up according to the actual situation on site, and can meet the safety requirements in different environmental conditions.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a three-in-one ladder track capable of supporting a climbing device in various environmental conditions, characterized in that: the three-in-one ladder track consists of a vertical track, a corner track, and a slope track; The main part of the vertical track is a vertical track base support frame, a plurality of first mounting plates are arranged on the back of the vertical track base support frame, the first mounting plates are fixed with mounting fasteners, a first limiting track is arranged on the track base support frame, and a first ladder cross bar is arranged between the first limiting tracks on both sides; The corner track is used to connect tracks of different working conditions. The main part of the corner track is a corner track base support frame. A plurality of second mounting plates are arranged on the back of the corner track base support frame. The second mounting plates are fixed with mounting fasteners. A second limiting track is arranged on the corner track base support frame. A second ladder cross bar is arranged between the second limiting tracks on both sides. The main part of the slope track is a slope track base support frame, and a plurality of third mounting plates are arranged on the back of the slope track base support frame. The third mounting plates are fixed with mounting fasteners. A third limiting track is arranged on the slope track base support frame, and the third limiting tracks on both sides are connected by a cross bar, and a third ladder cross bar for emergency evacuation of personnel is arranged directly below the third limiting track.

[0006] In a preferred solution, the first limiting track, the second limiting track and the third limiting track are connected to form a complete track system.

[0007] In a preferred solution, the first ladder cross bar, the second ladder cross bar and the third ladder cross bar are connected to form a complete ladder system.

[0008] In a preferred solution, racks are provided on the inner sides of the first limiting rail, the second limiting rail and the third limiting rail, and the racks are used to cooperate with the climbing device provided in the rail system. The first limiting rail, the second limiting rail and the third limiting rail are connected to form a complete rack.

[0009] In a preferred solution, the first ladder crossbar, the second ladder crossbar and the crossbar are provided with anti-fall rails to form a complete anti-fall system, brake platforms are provided at intervals on the anti-fall rails, and an avoidance groove is also provided on one side of the anti-fall rails; The anti-fall guide rail is used to cooperate with the climbing device body anti-fall device and the personnel anti-fall device to achieve the purpose of safely preventing the climbing device and passengers from falling during operation.

[0010] In a preferred solution, the anti-fall device achieves braking and locking of the climbing device on the track by cooperating with the braking platform through a rotating brake rod on the main body of the anti-fall device.

[0011] In a preferred solution, the anti-fall guide rail is further provided with a stop plate, which is used to limit the anti-fall device and the anti-fall guide rail to prevent the anti-fall device from falling off the anti-fall guide rail.

[0012] In the preferred scheme, the third mounting plate is an "L"-shaped plate, and the third mounting plate is fixed with mounting fasteners. A third limiting track is provided at one end of the "L"-shaped third mounting plate, and a third ladder cross bar is provided at the other end, forming a passage between the third limiting track and the third ladder cross bar.

[0013] In the preferred solution, the vertical track, corner track and slope track are standard parts made of high-strength alloy steel or stainless steel, which can be freely combined and used in three-dimensional space through connectors. Specifically, connectors can be used for docking, lengthening and installation according to on-site usage requirements.

[0014] The method for using the three-in-one ladder track based on the above climbing device is characterized by comprising the following steps: S1: After installing the track system, ladder system and fall prevention system according to the route, check whether the various connection parts of the ladder track are firm, and ensure that the first mounting plate, the second mounting plate and the third mounting plate are firmly connected to the mounting fasteners; S2: When the climbing device is used for passenger transportation, passengers wear safety belts.

After reaching the safe area, they release the connection between the chest suspension point of the safety belt and the anti-fall device to complete the emergency evacuation of the vertical working condition. S5: Emergency evacuation of personnel in slope conditions. When a fault occurs in slope conditions, the passengers first connect the safety rope on the back of the safety belt to the anti-fall device, then disconnect the chest hanging point of the safety belt from the anti-fall device, enter the third ladder crossbar and climb up or down to evacuate. After reaching the safe area, disconnect the safety rope on the back of the safety belt from the anti-fall device to complete the emergency evacuation of the slope condition; S6: Emergency evacuation passage for personnel under various working conditions. According to the layout of the three-in-one ladder track in the passage area, the corresponding evacuation passage can be rotated according to the current passage position of the current passengers. During the evacuation process, one hanging point of the safety belt (chest hanging point or back safety rope) must be connected to the anti-fall device to ensure the safe evacuation of passengers.
