[0022] Example 1

[0023] like Figure 1-4 As shown, this is the first embodiment of the present invention, which provides a KBK track trolley, including,

[0024] The main unit 1 includes two welded parts 101. The two welded parts 101 are welded together. The front and rear ends of the two welded parts 101 on the opposite side are provided with pulleys 102. The front and rear ends of the two pulleys 102 on the opposite side are fixedly connected with protective plates 103.

[0025] The hoisting unit 2 includes a fixed plate 201. The front and rear ends of the top of the fixed plate 201 are slidably connected to movable plates 202. Both sides of the top of the movable plates 202 are provided with lifting wheels 203. The bottom of the fixed plate 201 is fixedly connected to an mounting plate 204. The bottom of the mounting plate 204 extends between the two welded parts 101 and is connected to them by bolt threads.

[0026] like Figure 1-4 As shown, the welded component 101, pulley 102, and protective plate 103 are used to form the main body of the rail trolley. The fixed plate 201 is used to support the hanging wheel 203, and the hanging wheel 203 is used to support and guide the fixing rope. Since the position of the movable plate 202 at the top of the fixed plate 201 can be adjusted, the position of the hanging wheel 203 can be adjusted. This allows the position layout of the upper end of the lifting rope to be adjusted according to the volume of the goods being lifted, preventing the lifting rope from being difficult to fix due to excessive distance differences, or from falling off during the lifting process, thereby improving the stability and safety of the goods during the lifting process.

[0027] Example 2

[0028] Reference Figure 2 and 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] In this embodiment, the inner cavity of the fixing plate 201 is movably connected to a threaded rod 205 via a bearing. The threads at the front and rear ends of the threaded rod 205 are reversed, and threaded sleeves 206 are threadedly connected to both the front and rear ends of the threaded rod 205.

[0030] The top of the fixed plate 201 is provided with a through groove 207. The front and rear ends of the inner cavity of the through groove 207 are slidably connected with connecting blocks 208. The top of the connecting block 208 is fixedly connected to the movable plate 202, and the bottom of the connecting block 208 is fixedly connected to the threaded sleeve 206.

[0031] like Figure 2 and 3 As shown, the through groove 207 provides space for the connecting block 208 to move. The connecting block 208 connects the fixing plate 201 and the threaded sleeve 206, so that the fixing plate 201 can move with the threaded sleeve 206. Since the threads at the front and rear ends of the threaded rod 205 are set in opposite directions, when the threaded rod 205 rotates, it can drive the two threaded sleeves 206 to move synchronously and in opposite directions on its surface, thereby achieving the purpose of adjusting the distance between the two movable plates 202.

[0032] Example 3

[0033] Reference Figure 3 and 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0034] In this embodiment, limiting grooves 209 are provided on both sides of the fixed plate 201, and limiting frames 210 are fixedly connected to both sides of the bottom of the movable plate 202.

[0036] like Figure 3 and 4 As shown, the limiting groove 209 and the limiting frame 210 cooperate to support and limit the movable plate 202, preventing it from deflecting at an angle during movement. The rotating handle 211 acts as a threaded rod 205 to facilitate rotation, so as to adjust the position of the two movable plates 202.

[0037] Before hoisting the goods, the distance between the two fixed plates 201 needs to be adjusted according to the size of the goods. First, turn the handle 211. Turning the handle 211 will drive the threaded rod 205 to rotate. Since the threads at the front and rear ends of the threaded rod 205 are set in opposite directions, when the threaded rod 205 rotates, it can drive the two threaded sleeves 206 to move synchronously and in opposite directions on its surface, thereby achieving the purpose of adjusting the distance between the two movable plates 202. After the adjustment is completed, use the hoisting rope to fix the goods. After the goods are fixed, the trolley can be used to hoist the goods.
