The transmission gear 3 is rotatably connected to the gear shaft 5 and can be simultaneously meshed with the first gear 12 and the second gear 22.

In the embodiment, the mounting plate 4 is assembled with the first wheel axle 11 and the second wheel axle 21, preferably, one end of the mounting plate 4 along the first direction is provided with a first mounting hole, and the first mounting hole is matched with the first wheel axle 11, so that one end of the mounting plate 4 can be sleeved on the first wheel axle 11 through the first mounting hole; a second mounting hole is formed in the other end of the mounting plate 4 in the first direction, and the second mounting hole is matched with the second wheel shaft 21, so that the other end of the mounting plate 4 is sleeved on the second wheel shaft 21 through the second mounting hole; the mounting plate 4 is thus supported by the first and second axles 11, 21, and the first and second axles 11, 21 are able to rotate about their own axes.

Preferably, the first mounting hole and the second mounting hole are oblong holes, and the length direction of the oblong holes extends along the first direction, so that after the mounting plate 4 is mounted on the first wheel axle 11 and the second wheel axle 21, a displacement space exists between the mounting plate 4 and the first wheel axle 11 and the second wheel axle 21 only in the first direction, namely the front-back direction, and no displacement occurs in the second direction, namely the up-down direction, so that the distance between the first gear 12 and the second gear 22 is adjusted to a certain extent, the mounting of the transmission gear 3 is facilitated, and the transmission gear 3 can be simultaneously meshed with the first gear 12 and the second gear 22.

Preferably, the first wheel axle 11 and the second wheel axle 21 are relatively heavy at the joint of the mounting plate 4 and wear to some extent occurs, so that a wear-resistant sleeve is sleeved at the joint of the first wheel axle 11 and the second wheel axle 21 and the mounting plate 4, and the wear-resistant sleeve can be a wear-resistant copper sleeve, so that the first wheel axle 11, the second wheel axle 21 and the mounting plate 4 are protected to some extent.

In an embodiment of the present application, as shown in fig. 1 and 2, preferably, the mounting plate 4 is provided with a third mounting hole, and the third mounting hole is adapted to an end portion of the gear shaft 5, so that the end portion of the gear shaft 5 can be inserted into the third mounting hole, and thus the two mounting plates 4 support two ends of the gear shaft 5, so that the gear shaft 5 is stably mounted between the first wheel axle 11 and the second wheel axle 21, and the gear shaft 5 can provide stable support for the transmission gear 3, so that the transmission gear 3 can perform stable power transmission between the first gear 12 and the second gear 22.

Preferably, because a large load exists at the joint of the gear shaft 5 and the mounting plate 4, abrasion can be generated at the joint of the gear shaft 5 and the mounting plate 4, and a wear-resistant sleeve is sleeved at the joint of the gear shaft 5 and the mounting plate 4, so that the gear shaft 5 and the mounting plate 4 are protected to a certain extent; preferably, the wear-resistant sleeve is a wear-resistant copper sleeve.

So that the gear shaft 5 and the mounting plate 4 only have a space for relative displacement in the vertical direction, and the front and back displacement between the two does not occur; so that the gear shaft 5 can drive the transmission gear 3 to move up and down, and the transmission gear 3 can be meshed with or separated from the first gear 12 and the second gear 22 simultaneously.

Preferably, as shown in fig. 1, the power transmission device further includes a tension device 6 and a traction device 7; one end of the tension device 6 is fixedly connected with the mounting plate 4, the other end of the tension device 6 is connected with the gear shaft 5, and a downward pulling force can be provided for the gear shaft 5 through the tension device 6, so that the transmission gear 3, the first gear 12 and the second gear 22 can be tightly and stably meshed. The fixed end of the traction device 7 is connected with the balance beam 8, the driving end of the traction device 7 is connected with the gear shaft 5, and the traction device 7 can pull up the gear shaft 5 and the transmission gear 3 to enable the transmission gear 3 to be separated from the first gear 12 and the second gear 22; therefore, the positions of the gear shaft 5 and the transmission gear 3 in the vertical direction can be changed through the tension device 6 and the traction device 7, so that the transmission gear 3 can be meshed with or separated from the first gear 12 and the second gear 22 simultaneously; therefore, the position of the transmission gear 3 can be adjusted according to actual conditions, for example, in a gust environment, the transmission gear 3 is meshed with the first gear 12 and the second gear 22, so that the power equipment 13 on the first trolley assembly 1 drives the first trolley assembly 1 and the second trolley assembly 2 simultaneously, and the phenomenon that wheels of the second trolley assembly 2 slip is avoided; in the environment that the trolley can run stably, the transmission gear 3 can be separated from the first gear 12 and the second gear 22, the first trolley assembly 1 drives the wheel shaft and the wheels of the first trolley assembly 1 to roll through the power equipment 13, and the second trolley assembly 2 moves forwards through traction of the balance beam 8 in the moving process of the trolley, so that energy consumption is reduced, and the flexibility of moving the whole trolley is improved.

In this embodiment, the tensioning device 6 is preferably an elastic member capable of providing a downward elastic pulling force to the gear shaft 5. The traction device 7 can be a winch which can be a manual winch or an electric winch; the fixed end of the winch is arranged on the balance beam 8, and the driving end of the winch is connected with the gear shaft 5, so that the gear shaft 5 can be pulled upwards to separate the transmission gear 3 from the first gear 12 and the second gear 22; when the transmission gear 3 is required to be meshed with the first gear 12 and the second gear 22, the winch can lower the gear shaft 5, so that the gear shaft 5 is meshed with the first gear 12 and the second gear 22 under the pulling of the elastic member.
