[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] The core of the utility model is to provide an equipment cabin skirt system, which can reduce the constraints on the opening angle of the skirt.

[0044] For a specific embodiment of the equipment cabin skirt system provided by the utility model, please refer to Figures 1 to 12 , including a skirt panel 4, an upper side beam 5 and a lower side beam 6.

[0045] The top end of the skirt board 4 is detachably connected to the top rail 5. Specifically, the top end of the skirt board 4 is provided with a skirt board lock 9 to connect the top rail 5, and the skirt board lock 9 includes a tongue lock and a bump lock.

[0046] The skirt board 4 is rotatably connected to the lower side beam 6 via the rotating shaft 2, and the rotating shaft 2 is axially plugged into the bottom end of the skirt board 4 and the lower side beam 6, specifically, the skirt board sleeve fixedly arranged at the bottom end of the skirt board 4 and the lower side beam sleeve fixedly arranged at the lower side beam are respectively plugged into. Stoppers are respectively arranged at both ends of the rotating shaft 2 in the axial direction to prevent the rotating shaft 2 from axially separating from the lower side beam 6 and the skirt board 4.

[0047] At least one of the stoppers includes a locking member 3. For example, in this embodiment, one of the stoppers includes a locking member 3. A locking hole 22 is provided on the circumference of the rotating shaft 2. Figures 5 to 8 As shown, the locking member 3 includes a mounting tube 31 and a stop pin 32, the mounting tube 31 is fixed to the lower side beam 6, the stop pin 32 is inserted into and telescopically connected to the mounting tube 31, the stop pin 32 is inserted into the lock hole 22 by extending out of the mounting tube 31, or the stop pin 32 is withdrawn from the lock hole 22 by retracting relative to the mounting tube 31, wherein, when the mounting tube 31 and the rotating shaft 2 are respectively located on both sides of the lower side beam 6, the stop pin 32 can be inserted into the lock hole 22 through the through hole on the lower side beam 6. Among them, the skirt board 4 can be specifically an aluminum profile skirt board and a composite skirt board, and the rotating shaft 2 and the locking member 3 can be made of A2-70 stainless steel.

[0048] In this embodiment, since the skirt board 4 and the lower side beam 6 are connected by the rotating shaft 2 in a plug-in manner, under the constraint of the rotating shaft 2, the skirt board 4 will not fall off radially relative to the lower side beam 6 during the rotation relative to the lower side beam 6, and there is no need to hang it with a safety harness, which can reduce the constraint of the connection method at the bottom end of the skirt board 4 on the opening angle of the skirt board 4. In addition, since at least one stopper includes a locking member 3, the assembly and disassembly of the rotating shaft 2 can be facilitated, and the rotation of the rotating shaft 2 can be limited, thereby ensuring the stability of the assembly of the rotating shaft 2.

[0049] Regarding the setting mode of the locking member 3, as Figures 5 to 10 As shown, a first through hole 3111 is provided at the first end of the installation tube 31, a locking groove 314 is provided at the second end of the installation tube 31, and a positioning block 324 is fixed on the side of the limiting pin 32. When the limiting pin 32 extends out of the installation tube 31 through the first through hole 3111 and is inserted into the locking hole 22, the positioning block 324 is inserted into the locking groove 314, which can effectively limit the length of the limiting pin 32 extending out of the installation tube 31 to be inserted into the locking hole 22, thereby avoiding collision damage between the two.

[0050] like Fig.11 As shown, the second end of the installation tube 31 is further provided with an unlocking groove 313, the depth of the unlocking groove 313 is less than the locking groove 314, after the positioning block 324 is disengaged from the locking groove 314, the limiting pin 32 can rotate, and then the positioning block 324 can be plugged into the unlocking groove 313, and in the plugged state, the limiting pin 32 exits the lock hole 22. Through the plugging of the positioning block 324 and the unlocking groove 313, the limiting pin 32 can be effectively positioned to prevent the positioning block 324 from accidentally extending into the locking groove 314.

[0051] like Fig.10 As shown, the locking member 3 also includes an elastic member 33 arranged in the mounting tube 31. The elastic member 33 can make the limit pin 32 have a movement tendency close to the rotating shaft 2, thereby effectively preventing the limit pin 32 from detaching from the mounting tube 31 and ensuring that the limit pin 32 can remain in the plug-in state when inserted into the lock hole.

[0052] like Fig.10 As shown, the first end of the mounting tube 31 has an end plate 311, and the first through hole 3111 is opened in the middle of the end plate 311. The stop pin 32 includes a first rod body 321, a second rod body 322 and a pressure plate 323. The first rod body 321 is fixed to one end of the second rod body 322, and the pressure plate 323 is fixed to the side of the second rod body 322. The first rod body 321 is movably (including sliding and rotating) connected to the first through hole 3111, and the pressure plate 323 is movably (including sliding and rotating) arranged in the mounting tube 31. At least part of the structure of the second rod body 322 extends into the mounting tube 31. The elastic member 33 can make the pressure plate 323 have a movement tendency close to the end plate 311 and the rotating shaft 2. By adding the pressure plate 323, it is convenient for the elastic member to apply a force to the stop pin. Among them, the positioning block 324 is fixed to the second rod body 322.

[0053] like Fig.10 As shown, a baffle 312 is fixedly arranged in the installation cylinder 31, a second through hole 3121 is arranged on the baffle 312, and the second rod body 322 is movably connected to the second through hole 3121. The elastic member 33 is pressed between the pressure plate 323 and the baffle 312, which is convenient for assembling the elastic member 33, and can prevent the elastic member 33 from being separated from the installation cylinder 31, and ensure the stability of the movement of the second rod body 322. Specifically, the elastic member 33 can be a spring sleeved outside the second rod body 322. Of course, in other embodiments, the elastic member 33 can also be replaced by a magnetic member.

[0054] like Fig.11 As shown, the stop pin 32 further includes a rotating sleeve 325, which is sleeved on an end of the second rod body 322 that is away from the first rod body 321, so as to facilitate the rotation operation of the staff. In addition, the positioning block 324 can be fixed on the rotating sleeve 325. The rotating sleeve 325 can be screwed to the second rod body 322, so as to facilitate the assembly of the stop pin 32 and the mounting cylinder 31.

[0055] like Figure 6 As shown, among the two stoppers, one includes a locking member 3 and the other is a retaining ring 1 sleeved on the rotating shaft 2, which is beneficial to cost saving.

[0056] The retaining ring 1 can be a C-shaped elastic retaining ring for the shaft, and the stopper at one end of the rotating shaft 2 provided with the locking hole 22 also includes a convex ring 21 fixedly arranged on the outer peripheral surface of the rotating shaft 2, and the convex ring 21 and the retaining ring 1 are matched with the axial limiting skirt plate 4 and the lower side beam 6, and the locking hole 22 is arranged on the convex ring 21. When disassembling, the retaining ring 1 can be disassembled, and then the rotating shaft 2 is removed from the lower side beam 6 and the skirt plate 4. In addition, the convex ring 21 can be integrally formed on the rotating shaft 2, or the convex ring 21 can also be a bushing fixedly sleeved on the rotating shaft 2, specifically a nylon bushing. In other embodiments, the two stoppers can both be set as locking members 3.

[0057] The locking member 3 in this embodiment is a manual elastic stop structure, which can be manually driven to move the limit pin 32 to achieve insertion or disengagement from the lock hole, with a simple structure and convenient operation. In other embodiments, the limit pin 32 can also be connected to the inner wall of the installation cylinder 31 through a threaded structure to achieve the extension and retraction of the limit pin 32 by rotation; or the locking member 3 can also be directly set as a hydraulic cylinder, whose piston rod is the limit pin 32, so as to realize automatic control of the movement of the limit pin 32, or a driving motor is set between the rotating shaft 2 and the installation cylinder 31 to realize the automatic movement of the limit pin 32.

[0058] In addition, if Figure 4 As shown, after the top end of the skirt board 4 is separated from the upper side beam 5, the skirt board 4 can be turned downward relative to the rotating shaft 2 to a hanging state. In the hanging state, the weight of the skirt board 4 is balanced by the supporting force of the rotating shaft 2 on the skirt board 4, that is, the skirt board 4 hangs freely below the rotating shaft 2, which can provide sufficient space for the staff to do subsequent work.

[0059] In addition, if Figures 1 to 3 As shown, the frame 8 is located between the upper side beam 5 and the lower side beam 6, and a sealing strip 7 is provided on the skirt board 4. The frame 8 and the sealing strip 7 are crimped to form a seal. Among them, the main body thickness of the skirt board 4 is 20 mm unchanged.

[0060] In this embodiment, the working principle of the locking member 3 includes: adjusting the length of the stop pin 32 extending out of the installation tube 31 by controlling the extension of the locking member 3 to realize the opening and closing of the locking member 3. When opening, the stop pin 32 is lifted, so that the stop pin 32 retracts toward the installation tube 31, thereby disengaging from the lock hole 22 of the rotating shaft 2. At this time, the rotating shaft 2 can rotate relative to the skirt board 4 and the lower side beam 6, and move along its axial direction (specifically, it can correspond to the longitudinal center line direction of the vehicle body) and can be disengaged from the skirt board 4 and the lower side beam 6. The rotating shaft 2 can be taken out of the skirt board 4 to complete the disassembly of the skirt board 4; when closing, the stop pin 32 falls, so that the stop pin 32 extends out of the installation tube 31 and is inserted into the lock hole 22 of the rotating shaft 2. At this time, the rotating shaft 2 is fixed, and the rotating shaft 2 cannot move and rotate along its axial direction, and the installation of the skirt board 4 and the lower side beam 6 is completed.

[0061] In the equipment compartment skirt system of the present embodiment, the skirt 4 is rotatably connected to the lower side beam 6 by the rotating shaft 2, but the skirt 4 is flipped to a vertical state after being opened, which is convenient for equipment maintenance and disassembly and assembly of the skirt 4. While meeting the safety and convenience when disassembling and assembling the skirt 4, the length of the upper slide groove of the skirt 4 and other structures can be set as required to meet the lightweight of the skirt 4 as much as possible.
