Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, and particularly relates to a carriage loading and unloading auxiliary device for a detachable vehicle. Background Art

[0002] When installing a detachable carriage, the carriage needs to be accurately placed at the corresponding position on the vehicle frame, which requires relatively high driving skills for the driver. To reduce the docking difficulty between the carriage and the vehicle frame, our company previously designed a positioning and deviation-correcting buffer device for detachable vehicles, with the application number 2024207066865. After a period of application, although this positioning and deviation-correcting buffer device for detachable vehicles can better complete the assembly of the carriage and the vehicle chassis, the positioning accuracy required during installation is relatively high, and there is a small probability of minor misalignment during installation, which may cause a certain degree of deformation of relevant structures. Therefore, our company designed a carriage loading and unloading auxiliary device for detachable vehicles on the original basis. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies existing in the prior art and provide a carriage loading and unloading auxiliary device for a detachable vehicle. By setting a positioning chute plate, the positioning chute plate will rotate with the upper sliding frame during the falling process of the upper sliding frame, making its falling more stable and not requiring too high accuracy.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions: A carriage loading and unloading auxiliary device for a detachable vehicle includes a lower sliding frame installed on the vehicle chassis, an upper sliding frame installed on the carriage, and a positioning chute plate for assisting in docking and positioning between the upper sliding frame and the lower sliding frame; the lower sliding frame includes a bottom plate and two vertical plates fixedly connected to the bottom plate and arranged at an interval; a rotatable positioning chute plate is arranged between the two vertical plates; the upper sliding frame includes a lower inclined plate placed between the two vertical plates from top to bottom; when the carriage falls on the vehicle chassis, the lower inclined plate is erected on the top of the positioning chute plate.

[0005] Further, a groove for accommodating the upper sliding frame to be inserted is opened downward from the top in the middle of the vertical plate.

[0006] Further, the groove includes an upper flared part and a positioning part integrally communicated with the bottom of the flared part.

[0007] Further, a connecting block is fixedly connected to each of the two ends of the positioning chute plate close to the two vertical plates. The connecting block is provided with a through hole along the direction perpendicular to the vertical plate, and the vertical plate is provided with a second through hole corresponding to the through hole. A connecting pin simultaneously passes through the through hole and the second through hole.

[0008] The beneficial effects of the present utility model are as follows: By providing a positioning chute plate, when the upper sliding frame falls into the lower sliding frame, it first lands in the groove of the positioning chute plate. Since the bottom of the upper sliding frame is an inclined plate, the positioning chute plate will rotate along with the upper sliding frame during the falling process, making the falling of the upper sliding frame more stable. Initially, a high degree of precision is not required. After falling into the groove positioning part through the flared part, it will not be misaligned during the rotation of the positioning chute plate and can accurately complete the fitting installation of the upper sliding frame and the lower sliding frame. At the same time, the positioning chute plate has a certain buffering effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The present utility model will be further explained and described below in conjunction with the accompanying drawings and specific embodiments.

[0014] Embodiment:

[0015] As Figures 1 - 3 shown, a carriage loading and unloading auxiliary device for a detachable vehicle includes a lower sliding frame 1 installed on the vehicle chassis, an upper sliding frame 2 installed at the bottom of the carriage, and a positioning chute plate 105 for assisting in docking and positioning the upper sliding frame 2 and the lower sliding frame 1; the lower sliding frame 1 includes a bottom plate 101 and two vertical plates 102 fixedly connected to the bottom plate 101 and arranged at an interval; a rotatable positioning chute plate 105 is arranged between the two vertical plates 102; the two vertical plates 102 are parallel to each other, and the positioning chute plate 105 rotates around a straight line perpendicular to the vertical plates 102; the upper sliding frame 2 includes a lower inclined plate 201 placed between the two vertical plates 102 from top to bottom; when the bottom of the carriage falls on the vehicle chassis, the lower inclined plate 201 is erected on the top of the positioning chute plate 105, and the vehicle chassis is the vehicle frame; the upper sliding frame 1 and the lower sliding frame 2 in this application are the same as the upper sliding frame and the lower sliding frame in a positioning deviation correction and buffering device for a detachable vehicle.

[0016] A groove for accommodating the upper sliding frame 2 to be inserted is opened downward from the top in the middle of the vertical plate 102.

[0017] The groove includes a flaring portion at the upper part for facilitating the entry of the upper sliding frame 2 and a positioning portion integrally connected to the bottom of the flaring portion; the flaring portion is in the shape of an isosceles trapezoid, and the positioning portion is in the shape of a rectangle.

[0018] At both ends of the positioning chute plate 105 close to the two vertical plates 102, a connecting block 103 is fixedly connected respectively. The connecting block 103 is provided with a through hole along the direction perpendicular to the vertical plate 102. The vertical plate 102 is provided with a second through hole corresponding to the through hole. The connecting pin 104 passes through the through hole and the second through hole at the same time; the connecting block rotates relative to the vertical plate 102 through the connecting pin 104; the installation position of the connecting block 103 is lower than the lowest position where the corresponding position (i.e., the contact position or its vicinity) of the lower inclined plate 201 can fall.

[0019] By providing the positioning chute plate 105, when the upper sliding frame 2 falls into the lower sliding frame 1, it first lands in the groove of the positioning chute plate 105. Since the bottom of the upper sliding frame 2 is an inclined plate, the positioning chute plate 105 will rotate along with the upper sliding frame during the falling process, making the falling of the upper sliding frame more stable. At first, too high precision is not required. After falling into the positioning portion of the groove through the flaring portion, it will not be misaligned during the continuous falling process of the positioning chute plate 105, and the fitting installation of the upper sliding frame 2 and the lower sliding frame 1 can be accurately completed. At the same time, the positioning chute plate 105 has a certain buffering effect.

[0020] Working process: When the carriage is installed on the vehicle chassis, the carriage is lifted, the vehicle chassis runs to the bottom of the carriage, and then the carriage is lowered. The lower inclined plate 201 of the upper sliding frame 2 on the carriage enters the middle of the two vertical plates, and then enters the flaring portion of the positioning chute plate 105. After being preliminarily corrected by the flaring portion, it enters the positioning portion and is fixed. Then the upper sliding frame 2 continues to fall. At this time, it drives the positioning chute plate 105 to rotate in the direction away from each other until the upper sliding frame 2 completes the cooperation with the lower sliding frame 1.

[0021] The above is only used to illustrate the technical solution of the present invention and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, shall be covered within the scope of the claims of the present invention.
