[0038] Embodiment 1:

[0039] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes an anti-dumping ladder vehicle, including: a frame 1 located on a track 2; a plurality of wheels 3, and the plurality of wheels 3 are rotatably arranged on the frame 1; a fixed rod 4 is arranged on the frame 1, and a notch 5 is provided on the fixed rod 4; a rotating rod 6 is rotatably arranged in the notch 5; a rotating wheel 7 is rotatably arranged at one end of the rotating rod 6 close to the track 2, and after the rotating rod 6 rotates, the rotating wheel 7 abuts against the side of the track 2.

[0040] In this embodiment, the wheels 3 run on the track 2, and the wheels 3 abut against the side wall of the track 2. When the frame 1 is erected, the frame 1 can also be stably moved along the track 2, which not only ensures the free movement of the ladder vehicle on the track 2, but also plays a certain anti-dumping role, thereby improving the safety of the ladder vehicle. The frame 1 has a fixing rod 4, which is directly fixed to the frame 1 by welding. The direction in which the fixing rod 4 is set is perpendicular to the direction in which the frame 1 runs. The length of the fixing rod 4 is longer than the width of the track 2. The notch 5 is located on both sides of the fixing rod 4, closer to the track 2. When the rotating rod 6 rotates in the notch 5, the end of the rotating rod 6 close to the track 2 can approach and abut the track 2, thereby assisting the wheels 3 to play a role in fixing the frame 1, thereby improving the safety of the ladder vehicle. The rotating rod 6 has a rotating wheel 7 at one end close to the track 2. When the rotating rod 6 rotates and abuts against the track 2, the rotating wheel 7 will also abut against the side wall of the track 2. The function of the rotating wheel 7 is not only to make the frame 1 and the track 2 stronger and more stable, but also to enable the rotating wheel 7 to rotate, and no other operations are required when the frame 1 needs to be moved.

[0041] As a further technical solution, the rotating rod 6 is provided with a locking hole 8, and also includes: a plurality of locking blocks 9, which are arranged on the fixed rod 4, and the locking blocks 9 have a plurality of locking holes 10. After the rotating rod 6 rotates, the locking holes 8 correspond to different locking holes 10; there are a plurality of locking rods 11, and a plurality of locking holes 8 are slidably arranged in the locking holes 10. After the locking rods 11 slide, they penetrate the locking holes 10 and the locking holes 8.

[0042] In this embodiment, the locking rod 11 is used to lock the rotating rod 6. The locking rod 11 has multiple locking rods. When the locking rod 11 is rotated to a specified position, the locking rod 11 will slide through the locking hole 8 and enter another locking hole 10 to firmly lock the rotating rod 6. At this time, the rotating rod 6 can no longer rotate, ensuring that the rotating rod 6 and the rotating wheel 7 will not leave the track 2, further improving the safety of the ladder car. At the same time, when the rotating rod 6 is rotated to make the rotating rod 6 away from the track 2, operating another locking rod 11 can lock the rotating rod 6, so that the device can leave the track 2, ensuring that the ladder car will not be locked by the rotating wheel 7 when it is removed.

[0043] As a further technical solution, it also includes: a connecting rod 12 connects a plurality of locking rods 11 .

[0044] In this embodiment, the connecting rod 12 is used to connect multiple locking rods, which is convenient for users to operate and grasp, and can speed up the control speed of the locking rod 11, thereby improving the user experience.

[0045] As a further technical solution, it also includes: a pressure plate 13 is arranged on the locking rod 11; both ends of the first elastic member 14 are respectively arranged on the pressure plate 13 and the locking block 9, and the first elastic member 14 is used to provide force for the locking rod 11 to enter the lock hole 10.

[0046] In this embodiment, the first elastic member 14 is a spring, and may also be other elastic bodies with the same function. The first elastic member 14 can provide a force for the locking rod 11 to push into the lock hole 10, ensuring that the locking rod 11 is always located in the lock hole 10 without being affected by external forces, and ensuring the locking state of the locking rod 11. The pressure plate 13 provides a position for the installation of the first elastic member 14, which can stably connect the first elastic member 14 with the locking rod 11 to prevent the device from not working properly after the locking rod 11 is completely separated from the lock hole 10. The provision of the first elastic member 14 ensures that the locking rod 11 can be stably locked, and at the same time simplifies the operation of the locking rod 11 by the operator, thereby improving the safety performance.

[0047] As a further technical solution, one end of the locking rod 11 that penetrates into the locking hole 10 is in a frustum shape, and the cross-sectional area of ​​the locking rod 11 gradually decreases as it penetrates into the locking hole 8 .

[0048] In this embodiment, the cone at the end of the locking rod 11 can make it easier for the locking rod 11 to enter the locking hole 8. The rotating rod 6 does not need to adjust its position very accurately so that the locking rod 11 can enter the locking hole 8. At the same time, under the elastic force of the first elastic member 14, the locking rod 11 will automatically enter the locking hole 8. At the same time, under the action of the cone, the rotating rod 6 will be driven to rotate by the locking rod 11, and then the position of the rotating rod 6 is gradually adjusted to the optimal position, which reduces the difficulty of the operator and improves the efficiency of locking and unlocking.

[0049] As a further technical solution, the fixing rod 4 is a telescopic rod and further includes: a locking bolt 15 is arranged on the fixing rod 4 , and the locking bolt 15 is used to lock the fixing rod 4 .

[0050] In this embodiment, although the spacing between the rails 2 does not usually change, the size of the other side of the rail 2 that does not contact the wheel 3 during installation is relatively poor in accuracy, so the fixing rod 4 is designed to be retractable, and by adjusting the length of the fixing rod 4, slight errors between the rails 2 can be avoided, so that the frame 1 can be more stably fixed on the rail 2. The locking bolt can lock the fixing rod 4 so that its length does not change, which reduces the difficulty of adjustment while ensuring the installation quality and improves the installation speed.

[0051] As a further technical solution, the wheel 3 is truncated cone-shaped, and a plurality of wheels 3 work together to prevent the frame 1 from falling, and further includes: a locking member 16 is arranged on the frame 1, and the locking member 16 is used to clamp the wheel 3.

[0052] In this embodiment, the shape of the wheel 3 is similar to the wheel 3 of a train. The use of such a wheel 3 can ensure that the frame 1 can stably run on the track 2 without conflicting with the track 2, thereby improving the stability of the ladder car. The locking member 16 uses bolts or other parts that can increase the rotation resistance of the wheel 3. The locking member 16 is used to clamp the wheel 3 so that the wheel 3 cannot continue to rotate when the ladder car is working, thereby ensuring the stability of the ladder car.

[0053] Embodiment 2:

[0054] Reference Figure 5~Figure 6 The difference between this embodiment and embodiment 1 is that: it also includes a rotating frame 17, the rotating frame 17 is rotatably and slidably set on the fixed rod 4, the rotating wheel 7 is rotatably set on the rotating frame 17, after the rotating frame 17 rotates, the rotating wheel 7 abuts against the side wall of the track 2; the fastening sleeve 18 is set on the fixed rod 4, and the fastening sleeve 18 is used to limit the rotation and sliding of the rotating frame 17.

[0055] In this embodiment, the rotation and sliding of the rotating frame 17 can achieve the contact and cancellation between the rotating wheel 7 and the track 2, and the components that originally require two steps of adjustment are combined into one connection part, which is faster and more convenient when adjusting, and speeds up the installation time. The fastening sleeve 18 is connected to the fixing rod 4 through a thread. When the fastening sleeve 18 is screwed to the fixing rod 4, the rotating frame 17 will be tightly clamped on the fixing rod 4 by the fastening sleeve 18, thereby improving the fixing strength of the rotating frame 17.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
