Description

Technical Field

[0001] This utility model relates to the field of excavator cab technology, and in particular to an escape window structure for an excavator cab. Background Technology

[0002] An excavator cab escape window is a safety feature specifically designed for personnel evacuation in emergency situations. It is typically a special window located on the side, top, or rear of the cab, with a structure designed for easy and quick opening, such as being equipped with an emergency unlocking device, a manual operating handle, or a breaking device.

[0003] Currently, most excavator cab escape windows use emergency unlocking devices or manual operating handles to open the windows for escape. However, when people inside the cab cannot escape, the windows can only be broken by outsiders. During the breaking process, flying glass shards can easily cause secondary injuries to people inside the cab, posing a safety hazard. Utility Model Content

[0004] To address the above problems, this utility model provides a simple, convenient, and reliable escape window structure for excavator cabs.

[0005] The technical solution of this utility model is: an escape window structure for an excavator cab, comprising: A connecting frame and a window are provided. The window is hinged to the connecting frame. A shaft is connected to the middle of one side of the connecting frame, and a movable connecting rod is movably connected to the middle of the shaft. A first positioning sleeve is connected to the middle of one end of the movable connecting rod. A second positioning sleeve is provided on the connecting frame below the first positioning sleeve, and a positioning pin is connected between the first positioning sleeve and the second positioning sleeve.

[0006] A connecting rod is connected to one side of the outer surface of the second positioning sleeve, and one end of the connecting rod is attached to one side of the inner wall of the connecting frame and is threadedly connected to the connecting frame by a connecting bolt.

[0007] The inner wall of the connecting frame is symmetrically connected to one side of the frame with hinges, and the hinges are threaded to the window through a first screw at one end of the frame.

[0008] It also includes an anti-detachment component, which includes a post, a perforation, and an anti-detachment rope. The post is connected to the side of the outer surface of the window near the movable link. The perforation is opened through the upper part of the positioning pin. The end of the anti-detachment rope is connected to the post and the perforation respectively.

[0009] It also includes an auxiliary moving component, which includes a support plate and an electric push rod. The electric push rod is connected to the middle of the upper part of the support plate, and the output end of the electric push rod extends to the lower part of the interior of the second positioning sleeve.

[0010] The auxiliary activity component also includes a bracket, which is threadedly connected to the window body by a second screw that passes through the lower part, and the bottom of the bracket is in contact with the bottom of the support plate. The outer edge of the support plate is provided with threaded holes that extend into the bracket at equal intervals.

[0011] In operation, this invention utilizes a movable connecting rod to install the first positioning sleeve on the connecting frame supported by the window. The rotational characteristics of the movable connecting rod allow personnel outside the driver's cab to open the window at a 15° angle. Subsequently, they can directly pass through the gap and use their hands to disengage the positioning pin from the first and second positioning sleeves. This allows for escape for personnel trapped inside the driver's cab who are unable to escape without breaking the window, avoiding secondary injuries to those awaiting rescue caused by breaking the window, thus improving the effectiveness of the solution and meeting the required needs.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0016] Please see Figure 1-4 As shown, this utility model is an escape window structure for an excavator cab, comprising: A connecting frame 11 and a window 14 are connected. The window 14 is hinged to the connecting frame 11. A shaft 15 is connected to the middle of one side of the connecting frame 11, and a movable connecting rod 16 is movably connected to the middle of the shaft 15. A first positioning sleeve 17 is connected to the middle of one end of the movable connecting rod 16. A second positioning sleeve 19 is provided on the connecting frame 11 below the first positioning sleeve 17, and a positioning pin 18 is connected between the first positioning sleeve 17 and the second positioning sleeve 19. The connecting frame 11 provides the structural foundation installation environment. The opening and closing of the window 14 meets the protection and escape requirements of the cab. The shaft 15 is installed on the first positioning sleeve 17 through the movable connecting rod 16. When the first positioning sleeve 17 is opposite to the second positioning sleeve 19, the window 14 can be locked by fitting the positioning pin 18. With the help of the movement of the movable connecting rod 16, the window can be opened at a 15° angle, which is convenient for external personnel to carry out escape operations through the window 14.

[0017] A connecting rod 111 is connected to one side of the outer surface of the second positioning sleeve 19, and one end of the connecting rod 111 is attached to one side of the inner wall of the connecting frame 11 and is threadedly connected to the connecting frame 11 by a connecting bolt 110. The connecting rod 111 is used in conjunction with the connecting bolt 110 to complete the installation of the second positioning sleeve 19 structure.

[0018] Hinges 12 are symmetrically connected to one side of the inner wall of the connecting frame 11, and the hinges 12 are threaded to the window 14 through the first screw 13 at one end of one side. The hinge 12 secures the connecting frame 11 and the window 14 together with the first screw 13.

[0019] It also includes an anti-detachment component, which includes a post 21, a perforation 22 and an anti-detachment rope 23. The post 21 is connected to the side of the outer surface of the window 14 near the movable connecting rod 16. The perforation 22 is opened through the upper part of the positioning pin 18. The end of the anti-detachment rope 23 is connected to the post 21 and the perforation 22 respectively. The connection between the end of the anti-detachment rope 23 and the post 21 and the through hole 22 can limit the downward position of the detached positioning pin 18 and reduce the probability of loss.

[0020] When using window 14 for escape, if the person inside the driver's cab can operate it normally, they can directly disengage the positioning pin 18 from the first positioning sleeve 17 and the second positioning sleeve 19. If the person inside the driver's cab cannot perform the above operation, the person outside the driver's cab can act on window 14. Under the application of force, the movable connecting rod 16 connected to it will open window 14 at a small angle, i.e., 15°. Then, the person outside the driver's cab can extend their arm through the gap into the driver's cab and disengage the positioning pin 18 from the first positioning sleeve 17 and the second positioning sleeve 19, thus opening window 14.

[0021] This allows for easy opening of window 14 from outside the driver's cab without breaking it, thus facilitating escape and preventing injury to occupants from broken glass shards. This enhances usability and makes the system more convenient to use.

[0022] It also includes an auxiliary moving component, which includes a support plate 33 and an electric push rod 34. The electric push rod 34 is connected to the middle of the upper end of the support plate 33, and the output end of the electric push rod 34 extends to the lower part of the interior of the second positioning sleeve 19. The support plate 33 accommodates the installation of the electric push rod 34. The electric push rod 34, when controlled, positions the pin 18, which can mechanically open the window 14.

[0023] The auxiliary activity component also includes a bracket 31, which is threadedly connected to the window 14 by a second screw 32 that passes through the lower part, and the bottom of the bracket 31 is in contact with the bottom of the support plate 33. The outer edge of the support plate 33 is provided with threaded holes that extend into the bracket 31 at equal intervals. The threaded hole, in conjunction with the external bolt, can fix the support plate 33 and the bracket 31, that is, fix the electric push rod 34. The bracket 31 provides the structural foundation installation environment. The second screw 32 installs and fixes the bracket 31. The threaded connection facilitates the disassembly and assembly of the structure.

[0024] After the window 14 is opened at a small angle, if the person outside the driver's cab cannot extend their arm into the cab through the gap, the controlled electric push rod 34 is used to act on the output end. By moving the output end upward and acting on the positioning pin 18, the positioning pin 18 can be mechanically disengaged from the first positioning sleeve 17 and the second positioning sleeve 19.

[0025] This allows the person outside the driver's seat to open window 14, further improving the usability.
