[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4The crawler transport vehicle frame for convenient crawler maintenance includes a frame body, a driving assembly and a protective assembly. The frame body includes a crawler body 1, a driving wheel 2 and a base 3. The driving wheels 2 are symmetrically arranged at the four corners of the base 3. The crawler body 1 is sleeved on the driving wheels 2 on the same left and right sides. The protective assembly includes a protective cover 4, a support beam 5 and a guide rod 6. The support beam 5 is arranged on the bottom wall of the protective cover 4 near the center end of the base 3. The guide rods 6 are symmetrically arranged on the left and right sides of the support beam 5 near the center end of the base 3. A guide groove matched with the guide rod 6 is provided on the base 3, and the driving assembly includes a motor 7, a first bevel gear 8, a second bevel gear 9 and a forward and reverse screw 10. A movable groove is provided in the base 3, and the motor 7 is arranged on the bottom wall of the movable groove. The output end of the motor 7 is connected to the first bevel gear 8. The forward and reverse screw 10 passes through the center of the base 3, and a screw hole threadedly connected to the forward and reverse screw 10 is provided in the center of the support beam 5. The center of the forward and reverse screw 10 is sleeved with a second bevel gear 9 meshing with the first bevel gear 8.

[0023] The base 3 is provided with a driving wheel 2 and a crawler body 1 on the left and right sides. The base 3 provides stable support and power source for the driving wheel 2. The crawler body 1 is sleeved on the driving wheel 2. The protective cover 4 is provided with a support beam 5. The support beam 5 is provided with a guide rod 6 which is slidably connected to the base 3. When the guide rod 6 is inserted into the guide groove, the support beam 5 is connected to the end of the forward and reverse screw 10, and the motor 7 is started. The motor 7 drives the first bevel gear 8 to rotate, and the second bevel gear 9 is fixedly connected to the forward and reverse screw 10. The second bevel gear 9 is meshed with the first bevel gear 8. With the rotation of the forward and reverse screw 10, the two groups of protective covers 4 with support beams 5 move toward each other. The motor 7 adopts a stable servo motor 7.

[0024] During actual use, the protective cover 4 needs to be lifted for assembly. For this purpose, two groups of symmetrically arranged handles 11 are provided on the protective cover 4, and storage grooves adapted to the handles 11 are provided on the left and right sides of the base 3. When the side walls of the protective cover 4 are attached to the track body 1, the handles 11 are completely stored in the storage grooves.

[0025] If the guide rod 6 is cylindrical, it is inconvenient to align the guide rod 6 with the guide groove. For this reason, a conical block 12 is provided at one end of the guide rod 6 close to the guide groove, and a reinforcing plate 13 is provided on the side of the protective cover 4 away from the base 3 to ensure its strength when the equipment is placed.
