Description

TECHNICAL FIELD

[0001] The utility model relates to the transport vehicle accessory technical field, and the specific field is a detachable floor assembly. BACKGROUND

[0002] In the related technical field, railway transportation is well-known for its strong transportation capacity, fast transportation speed and low cost. The double-layer transport automobile special vehicle has become the main model of railway transport automobile because it can load a large number of automobiles and adapt to various vehicle models. The middle part of the bottom frame of the vehicle adopts a concave bottom structure to meet the loading requirements of higher vehicle models. The middle concave bottom and the end part are connected through an 11° slope transition, so that most car models can smoothly pass through the slope transition area. However, for some low chassis cars, scratches may occur between the car chassis and the bottom frame floor. At present, the main solution is to lay four non-metallic material pads at the four corners of the lower bottom frame concave bottom, that is, to add additional pads in the slope transition area.

[0003] In the process of implementing the embodiments of the present disclosure, we found that the related technology at least has the following problems:

[0004] The contact state of the pad and the bottom frame floor of the vehicle body is not good, and it cannot be firmly connected with the bottom frame floor of the vehicle body. When the car passes, the wheels roll over the pad, which causes a large displacement of the pad position, resulting in vehicle bumping and abnormal noise. The existing pad is made of non-metallic composite material, which is easy to break and fail after a long time of being rolled by the car wheels due to insufficient strength, resulting in a high replacement frequency during maintenance. UTILITY MODEL CONTENTS

[0005] The purpose of the utility model is to provide a detachable floor assembly to solve the problems raised in the background technology.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a detachable floor assembly, comprising a bottom fixed plate and a detachable pad, a right-angle-shaped clamping groove is specially designed on the upper wall surface of the bottom fixed plate, and a right-angle-shaped clamping piece matched with the clamping groove is arranged on the lower wall surface of the detachable pad. The mutual embedding between the right-angle-shaped clamping groove and the right-angle-shaped clamping piece ensures the stable positioning of the pad on the bottom fixed plate, thereby improving the stability and durability of the overall floor assembly.

[0007] In order to further enhance the fixing effect of the pad, a positioning column is arranged on the bottom fixed plate, and a positioning hole is arranged on the wall of the detachable pad. The positioning column can be accurately inserted into the positioning hole and extend above the positioning hole, which can effectively prevent the pad from moving left and right during use, and ensure the stability of the floor assembly during use.

[0008] In order to prevent the up and down movement of the pad, the utility model also specially designs that the upper middle part of the positioning column is provided with an installation notch, and the installation notch is provided with a clamping plate. The plate wall of the clamping plate is provided with an arc-shaped opening, and the arc-shaped opening is provided with a fixed pin. The two ends of the fixed pin are fixedly arranged on the two inner side walls of the installation notch and move along the length direction of the clamping plate. Through the connection of the arc-shaped opening and the fixed pin, the detachable pad can be extruded and fixed, so that the upward and downward movement of the pad is prevented, and the overall stability of the floor assembly is further enhanced.

[0009] In order to improve the wear resistance of the pad, the utility model also preferably provides a wear-resistant layer on the upper surface of the detachable pad. The wear-resistant layer can effectively resist the wear of the surface of the pad in daily use, prolonging the service life of the floor assembly.

[0010] Compared with the prior art, the utility model has the beneficial effects that: the connection stability of the pad and the vehicle body frame floor is improved, and the bumping and abnormal sound during the driving of the vehicle are reduced.

[0011] Through the embedding design of the right-angle clamping groove and the right-angle clamping piece, the fixed position of the pad is ensured to be accurate, and the displacement of the pad is avoided.

[0012] The design of the positioning column and the positioning hole enables the pad to be accurately positioned on the frame, further enhancing the stability of the pad.

[0013] The combination design of the clamping plate and the fixed pin allows the pad to be extruded and fixed, improves the firmness of the pad, and reduces the damage and replacement frequency of the pad caused by the driving of the vehicle.

[0014] The upper surface of the detachable pad is provided with a wear-resistant layer, prolonging the service life of the pad and reducing the maintenance cost.

[0015] The pair of right-angle clamping grooves and the pair of right-angle clamping pieces are equal in number, ensuring the uniform stress of the pad and the symmetry of the overall structure.

[0016] The extension direction of the installation notch is the same as the length direction of the clamping plate, and the length direction of the fixed pin is perpendicular to the length direction of the clamping plate, so that the fixed pin can more effectively extrude and fix the pad, further improving the stability and durability of the pad.
