[0033] The first plug-in plate 8 and the second plug-in plate 9 inserted into the slot 11 are locked by the pin rod positioning assembly. Specifically, the pin rod positioning assembly comprises a threaded hole 12 formed on the outer side of the sliding seat 1, the threaded hole 12 being in communication with each slot 11, a threaded rod 14 being threadedly connected in the threaded hole 12, one end of the threaded rod 14 extending to the outside of the sliding seat 1, the threaded rod 14 penetrating each first plug-in plate 8 and each second plug-in plate 9, and a limiting hole 10 being formed on the first plug-in plate 8 and the second plug-in plate 9 and being threadedly connected with the threaded rod 14.

[0034] The first plug-in plate 8 and the second plug-in plate 9 are alternately inserted into the corresponding slots 11, the threaded rod 14 is screwed into the threaded hole 12, the threaded hole 12 sequentially penetrates each first plug-in plate 8 and each second plug-in plate 9, the threaded hole 12 locks the first plug-in plate 8 and the second plug-in plate 9 in the slot 11 by cooperating with the limiting hole 10 on the first plug-in plate 8 and the second plug-in plate 9, and the slot 11 supports and limits the first wheel seat 4 and the second wheel seat 5 by cooperating with the first plug-in plate 8 and the second plug-in plate 9, so that the first wheel seat 4 and the second wheel seat 5 are easily disassembled and used safely.

[0035] In the preferred scheme, in order to strengthen the sealing of the cooperation between the threaded rod 14 and the threaded hole 12, the threaded rod 14 is fixedly connected with a sealing plug 16 at the end away from the slot 11, the sealing plug 16 is fixedly connected with a screw head 15 at the end away from the threaded rod 14, and the sealing plug 16 is slidably connected with a sealing groove 13 formed at the port of the threaded hole 12. After the threaded rod 14 is screwed into the threaded hole 12, the sealing plug 16 fixed with the threaded rod 14 is also screwed into the sealing groove 13, preventing rainwater from entering the sealing groove 13 and causing the threaded rod 14 to rust. The screw head 15 plays a role in facilitating rotation.

[0036] In order to improve the structural strength of the cooperation between the sliding seat 1 and the first wheel seat 4, support plates 6 are fixedly connected to the left and right sides of the sliding seat 1, the support plates 6 are arranged at the lower end of the first wheel seat 4, and the connection between the support plates 6 and the sliding seat 1 is provided with reinforcing ribs. The support plates 6 can play a role in assisting the support of the first wheel seat 4.

[0037] The crane assembly type self-propelled mechanism hoists the heavy object by the winding device, adjusts the horizontal position of the sliding seat 1 by moving the sliding device on the guide rail, and cooperates with the winding device to transport the heavy object to the target area. The sliding device comprises the first wheel seat 4 and the second wheel seat 5 arranged on the left and right sides of the sliding seat 1. When the first wheel seat 4 and the second wheel seat 5 are installed, the first plug-in plate 8 on the first wheel seat 4 and the second plug-in plate 9 on the second wheel seat 5 are respectively inserted into each slot 11 formed on the left and right sides of the sliding seat 1. After being limited by the slot 11, the pin rod positioning assembly installed on the outer side of the sliding seat 1 cooperates with the first plug-in plate 8 and the second plug-in plate 9 to limit the movement of the first plug-in plate 8 and the second plug-in plate 9 in the slot 11, thereby completing the fixation between the first wheel seat 4, the second wheel seat 5 and the sliding seat 1.
