[0027] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, and are intended to explain the utility model, and cannot be understood as limiting the utility model. Embodiment 1

[0028] As Figures 1 to 6 shown, a car compartment limiting device for detachable vehicle, including fixedly connected to the bottom plate 1 of detachable vehicle frame, still include the limiting plate 2 of fixedly connected to the top of bottom plate 1, and the reinforcing frame 3 of fixedly connected to the inner side of limiting plate 2.

[0029] The bottom plate 1 is fixedly connected to the middle part of the front side of the detachable vehicle frame, the distance between the bottom plate 1 and the rear side of the detachable vehicle frame is equal to the length of the carriage to be assembled, by setting the limiting plate 2 in the middle part of the front side of the detachable vehicle frame, when the detachable vehicle frame is reversed into the hydraulic support under the carriage, after the longitudinal position of the carriage and the detachable vehicle frame is aligned, the limiting plate 2 is on the front end of the carriage, the driver judges whether they are aligned according to the signal transmitted by the limiting block on the frame, thereby improving the accuracy and efficiency of the assembly of the carriage and the frame of the detachable vehicle.

[0030] As shown in Figures 1 to 6 , the limiting plate 2 is a bent right angle plate, the right angle of the limiting plate 2 is opposite to the rear of the detachable vehicle frame, by setting the limiting plate 2 as a right angle plate, the right angle structure has strong stability, when the carriage contacts the limiting plate 2, it can withstand a large impact force, so that the limiting plate 2 remains stable during long-term use, avoiding the situation that the limiting plate 2 is deformed by impact during use, resulting in inaccurate limiting;

[0031] Further, the part of the right angle limiting plate 2 in contact with the carriage is the right angle end of the limiting plate 2, which limits the longitudinal position of the carriage while having a small contact area with the carriage, so that the transverse friction between the limiting plate 2 and the carriage is small, reducing the influence of the limiting plate 2 on the transverse positioning and correction of the carriage.

[0032] As shown in Figures 1 to 4 , a round corner is provided on the outer side of the right angle of the limiting plate 2, and a corrosion-resistant and wear-resistant layer is applied to the outer side of the right angle of the limiting plate 2, by providing a round corner on the right angle of the limiting plate 2, the area of the limiting plate 2 in contact with the carriage is increased, avoiding damage to the carriage caused by the edges of the limiting plate 2 during docking, and the contact area between the round corner of the limiting plate 2 and the carriage is small, which can minimize the influence of the friction between the limiting plate 2 and the carriage on the transverse position adjustment of the carriage, making the transverse positioning and adjustment of the carriage more smooth, and the corrosion-resistant and wear-resistant layer on the outer side of the limiting plate 2 prolongs the service life of the limiting plate 2, avoiding the situation that the limiting plate 2 is corroded for a long time, and also avoiding the situation that the outer side of the limiting plate 2 is worn during the transverse adjustment of the carriage. Embodiment 2

[0033] As shown in Figures 5 to 6 , the limiting plate 2 is arc-shaped, and the arc surface of the limiting plate 2 faces the rear of the detachable vehicle frame, by setting the limiting plate 2 as arc-shaped, when the arc surface of the limiting plate 2 is impacted, the arc surface can disperse the impact, reducing the influence of the impact force on the arc-shaped limiting plate 2, and the arc surface of the limiting plate 2 can reduce the bumping or wear on the carriage.

[0034] As shown in Figures 1 to 6As shown, the upper half of both sides of the limiting plate 2 is inclined, and the top of the inclined surfaces on both sides of the limiting plate 2 is rounded. By setting the two sides of the limiting plate 2 as inclined, the contact area between the bottom of the limiting plate 2 and the base plate 1 is increased, thereby improving the overall stability of the limiting device. At the same time, the main contact part between the limiting plate 2 and the carriage is the lower half. Reducing the material used in the upper half of the limiting plate 2 can reduce production costs without affecting its limiting effect. The rounded corners on both sides of the top of the limiting plate 2 can prevent the top edges of the limiting plate 2 from causing injury to the carriage or operators. Example 3

[0035] like Figures 1 to 6 As shown, the reinforcing frame 3 is set inside the limiting plate 2. The horizontal cross section of the reinforcing frame 3 is rectangular, and the top of the reinforcing frame 3 is closed. By setting the reinforcing frame 3 on the rear side of the limiting plate 2, the two work together to form a stable support structure, which further improves the impact resistance of the limiting device.

[0036] When the limit plate 2 is mounted on the frame, its top height is much higher than the bottom height of the carriage when it is hydraulically lifted. By limiting the height of the limit plate 2, it can limit the contact between carriages of different heights, thus preventing the limit plate 2 from failing due to the carriage being raised too high.

[0037] The working principle of this utility model is as follows:

[0038] S1. When the longitudinal position of the carriage is aligned with that of the detachable vehicle frame, the limiting plate 2 is placed against the front end of the carriage. The driver judges whether the two are aligned based on the signal transmitted by the upper limit block of the frame, thereby improving the accuracy and efficiency of the assembly of the carriage and frame of the detachable vehicle.

[0039] S2. The right-angle structure has strong stability and can withstand a large impact force when the carriage comes into contact with the limiting plate 2, so that the limiting plate 2 can maintain a stable state during long-term use and avoid the limiting plate 2 being deformed by impact during use, which would lead to inaccurate limiting.

[0040] S3. Rounded corners are made on the right angle of the limiting plate 2 to increase the contact area between the limiting plate 2 and the carriage, so as to avoid damage to the carriage by the sharp corners of the limiting plate 2 during docking. At the same time, the small contact area between the rounded corners of the limiting plate 2 and the carriage can minimize the impact of the friction between the limiting plate 2 and the carriage on the lateral position adjustment of the carriage, making the lateral positioning adjustment of the carriage smoother.

[0041] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
