[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, an embodiment of the present invention provides a trolley for preventing a vehicle body frame from falling, and the trolley includes: a base 1, a track 2, a slider 3, a vehicle body frame 4, a limiter 5 and a guide rail 6; wherein the track 2 is fixed on the base 1, the vehicle body frame 4 is connected to the slider 5, and the vehicle body frame 4 moves on the track 2 through the slider 5; there are two guide rails 6, and the two guide rails 6 are respectively located on both sides above the track 2, the vehicle body frame 4 is located above the guide rails 6, and the limiter 5 is installed on the guide rails 6.

[0025] In this embodiment, a balancing rail is used to improve the stability of the vehicle body frame, and a limiter is used to fix the vehicle body frame to limit the left and right shaking and forward and backward movement of the vehicle body frame to meet the horizontal stability and ensure that the trolley frame will not fall over the travel. However, when the vehicle body needs to be transferred, the limiter can be released from the vehicle body frame, and then the slider can move in the track.

[0026] like Figure 2 As shown, in one embodiment of the present disclosure, the two guide rails 6 are on the same horizontal plane and the two guide rails 6 are parallel.

[0027] In one embodiment of the present disclosure, two limiters 5 are installed on each guide rail 6 , and the two limiters 5 are located at two landing points of the vehicle body frame 4 on the same guide rail 6 .

[0028] In this embodiment, if Figure 3 The limiter 5 shown may include a fixing portion 51, a flipping portion 52 and a limiting portion 53, wherein the fixing portion is connected to the limiting portion via the flipping portion, the fixing portion is fixed to the guide rail, the limiting portion can be folded onto the guide rail via the folding portion to limit the movement of the vehicle body frame, and the limiting portion can be folded outward of the guide rail via the folding portion to release the restriction on the vehicle body frame. The structure of the limiter can be set by itself, and any limiter disclosed in the present invention can be used as long as it can achieve the effect of limiting the movement of the vehicle body frame and releasing the restriction on the vehicle body frame.

[0029] In one embodiment of the present disclosure, two stoppers 5 are located outside or at the outer sides of two landing points of the vehicle body frame 4 on the same guide rail 6 .

[0030] In this embodiment, the two stoppers 5 are located inside the two landing points of the vehicle body frame 4 on the same guide rail 6. To ensure adequate safety, the distance between the stopper and the nearest landing point can be smaller than the distance between the landing point and the nearest end point of the guide rail. The two stoppers 5 are located outside or inside the two landing points of the vehicle body frame 4 on the same guide rail 6. Although the stoppers do not contact the vehicle body frame, the vehicle body frame has a certain movable travel on the guide rail, but will not fall from the guide rail.

[0031] In one embodiment of the present disclosure, two limiters 5 are installed on each guide rail 6, the two limiters 5 on one guide rail 6 are located at two landing points of the vehicle body frame 4 on the same guide rail 6, and the two limiters 5 on the other guide rail 6 are located on the inner side or the outer side of the two landing points of the vehicle body frame 4 on the same guide rail 6.

[0032] In this embodiment, two limiters on one guide rail are located at two landing points of the vehicle body frame on the same guide rail, and two limiters on the other guide rail are located inside or outside the two landing points of the vehicle body frame on the same guide rail. Although some limiters are not in contact with the vehicle body frame, they will not fall off the guide rails.

[0033] In one embodiment of the present disclosure, only one limiter 5 may be installed on each guide rail 6, as long as the movement of the vehicle body frame can be restricted and the restriction on the vehicle body frame can be released without causing the vehicle body frame to fall off the guide rail.

[0034] In one embodiment of the present disclosure, a plurality of limiters 5 can be installed on each guide rail 6, and the number is not limited, as long as the movement of the vehicle body frame can be restricted and the restriction on the vehicle body frame can be released so as to prevent the vehicle body frame from falling off the guide rail.

[0035] In one embodiment of the present disclosure, the trolley further includes: a track correction device 7, and the track correction device 7 is located at one end where the track 2 is connected to the external track.

[0036] In this embodiment, a track correction device is provided to ensure accurate connection with the external track, limit the overall movement of the trolley, and enable the slider to smoothly move from the track 2 to the external track, thereby ensuring normal operation of the vehicle body frame.

[0037] like Figure 4 As shown, in one embodiment of the present disclosure, the track correction device 7 includes at least four baffles 71 connected to the top of the track 2, and each side around the top of the track 2 is connected to at least one baffle.

[0038] In this embodiment, the baffle can be integrally formed with the track or can be hinged together. At least four baffles are used to limit the connection position between the track 2 and the external track, ensuring accurate connection with the external track, limiting the movement of the trolley as a whole, so that the slider can smoothly move from the track 2 to the external track, and ensuring the normal operation of the body frame. The structure of the track correction device can be changed as long as it can achieve accurate connection with the external track, limit the movement of the trolley as a whole, and ensure the normal operation of the body frame.

[0039] In one embodiment of the present disclosure, the trolley further includes: a push rod 8, which is connected to the base 1 and is located on a side corresponding to the track correction device.

[0040] In this embodiment, a push rod is provided to facilitate the movement of the trolley, thereby facilitating the trolley to be used in the conveyor line used for automobile body welding processing production to transport the body processing trolley frame to various welding processing platforms through a lift to perform various body welding project operations.

[0041] In one embodiment of the present disclosure, the push rod 8 and the base 1 are detachably connected.

[0042] In this embodiment, a detachable connection is provided between the push rod and the base, so that the trolley can be easily stored and transferred.

[0043] The present invention utilizes a balancing guide rail to improve the stability of the vehicle body frame, adopts a limiter to fix the vehicle body frame, limits the movable range of the vehicle body frame, and enhances the stability of the vehicle body frame. A track correction device is provided at the end of the trolley track to achieve smooth transfer of the vehicle body, thereby effectively preventing personal injury and equipment damage.
