[0002] Gantry cranes, also known as portal cranes or bridge cranes, are mainly used to move heavy objects and are commonly found in places such as ports, cargo yards, shipyards, construction sites, and large manufacturing plants. The gantry crane busbar system is a device specifically used to provide power to the gantry crane. The gantry crane can continuously receive power while moving on the track to drive its movement and operate the load. The busbar brush holder is a key component in the busbar system used to support and guide the carbon brushes, also known as the collector holder. The function of the carbon brush is to establish a stable electrical contact between the collector and the busbar rail to transmit power to the moving equipment.

[0003] The carbon brush holder of the gantry crane busbar consists of two groups, front and back, which are connected together. When a carbon brush holder in one group breaks or has other faults, a chain failure will occur in the other group due to inertia, which is very dangerous and has high maintenance costs. In addition, the position of the carbon brush holder is relatively fixed at present. There will be a certain error after the carbon brush holder is installed, so it needs to be removed and reinstalled. The calibration process is cumbersome and complicated, time-consuming and labor-intensive, and has low work efficiency. It is impossible to adjust the position of the carbon brush holder to a certain extent, so the carbon brush holder cannot be in a good working condition, and the use effect is poor.

[0054] By pressing the pressure plate 182, the pressure rod 181 will be driven to move and the first elastic member 184 will be compressed. The pressure rod 181 will drive the first wedge block 183 to move toward the transmission cavity 19. The cooperation of the first wedge block 183 and the transmission assembly 186 will drive the limiting block 185 to move toward the transmission cavity 19 until the limiting block 185 does not affect the insertion of the plug block 16. After the plug block 16 of the mounting seat 11 is inserted into the corresponding slot 15 on the connecting seat 10, and then the pressure plate 182 is released, the rebound force of the first elastic member 184 will restore the pressure plate 182 and the first wedge block 183 to their initial positions. The transmission assembly 186 will also move the limiting block 185 and enter the limiting groove 17 of the plug block 16, so that the plug block 16 is fixed by the limiting block 185, that is, the mounting seat 11 and the connecting seat 10 are connected and fixed.

[0055] In this embodiment, preferably, please refer to Figure 9-10 The transmission assembly 186 includes: a second wedge block 1861 and a third wedge block 1862, both of which are slidably disposed in the transmission cavity 19 and slide in contact with each other, and the second wedge block 1861 is slidably adapted to the first wedge block 183; a connecting rod 1863, one side of which is connected to the third wedge block 1862, and the other side is connected to the limiting block 185.

[0056] In this embodiment, preferably, please refer to Figure 9-10 The connecting rod 1863 and the third wedge block 1862 are connected by a vertical rod 20. A plurality of slide grooves 21 are provided in the transmission cavity 19. The vertical rod 20 and the second wedge block 1861 are provided with a slide rod 22 slidably connected to the slide groove 21. A second elastic member 23 is provided between the slide rod 22 and the inner wall of the slide groove 21. The second elastic member 23 in the present application is a spring. Fig.10For example, when the first wedge block 183 moves downward, the second wedge block 1861 moves left, which will drive the sliding rod 22 connected to it to move left along the sliding groove 21 and compress the second elastic member 23. At this time, the third wedge block 1862 will drive the vertical rod 20 to move upward, and the vertical rod 20 will drive the sliding rod 22 connected to it to move along the sliding groove 21 and compress the second elastic member 23; and when the first wedge block 183 moves upward, through the rebound force of the second elastic member 23, the second wedge block 1861 will move right, and the third wedge block 1862 will move downward, that is, the limiting block 185 will move downward.

After the side of the limiting block 185 facing the opening of the slot 15 is an inclined surface, there is no need to press the pressure plate 182 before the insert block 16 is inserted into the slot 15. When the insert block 16 is inserted into the slot 15, the limiting block 185 will be squeezed so that the limiting block 185 enters the displacement groove 24. When the insert block 16 is inserted into the specified position in the slot 15, the limiting block 185 is located at the limiting groove 17 position of the insert block 16. The limiting block 185 will move downward into the limiting groove 17 after being free from pressure, thereby limiting and fixing the insert block 16 and the mounting seat 11.
