[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a tower crane for the construction of gas station canopies, which has the following advantages:

[0017] 1. Insert the four posts on the connecting frame into the four slots on the lower connecting frame. Then rotate the first shaft. The first shaft drives the first bevel gear to rotate, which in turn drives the two second bevel gears to rotate. The two second bevel gears drive the corresponding second shaft and the first screw to rotate. The rotation of the first screw causes the square post to move closer to the post and insert it into the slot, thus fixing the post inside the slot and connecting the two connecting frames together. This avoids the need to use multiple bolts to install the connecting frames, saving time and improving the efficiency of tower crane tower body construction.

[0018] 2. A first handle is fixedly connected to the side end of the first rotating shaft, and a regular hexagonal column is fixedly connected to the side end of the first handle. When the electric wrench is placed on the outside of the regular hexagonal column, the electric wrench drives the regular hexagonal column, the first rotating shaft and the first bevel gear to rotate, which facilitates the quick adjustment of the position of the two corresponding square columns and saves manpower.

[0019] 3. By rotating the second screw, the slide plate slides inside the sliding groove. The slide plate drives the connecting plate and the locking pin to move, so that the locking pin is inserted into the fixing groove on the upper side of the first throttle. During the operation of the tower crane, the first throttle is prevented from rotating by itself, ensuring the firmness of the connection between the two adjacent connecting frames.

[0029] Please see Figures 1-5 A tower crane for constructing a gas station canopy includes a connecting frame 1. A fixed frame 2 is fixedly connected to the top of the connecting frame 1. Slots 3 are provided at the four corners of the top of the fixed frame 2. Inserts 4, which are compatible with the slots 3, are fixedly connected to the four corners of the bottom of the connecting frame 1. The side of the insert 4 is provided with a slot 5. Two grooves 6 are symmetrically arranged on the fixed frame 2. The grooves 6 are connected to the corresponding square grooves 7 through square grooves 7. A square post 8, which is compatible with the slot 5, is slidably arranged inside the square groove 7. A first screw 9 is threadedly connected to the square post 8. A sealing plate 10 is fixedly connected to the fixed frame 2 at the position corresponding to the grooves 6. A sealing gasket 26 is provided between the sealing plate 10 and the fixed frame 2 to ensure the sealing between the sealing plate 10 and the fixed frame 2. A first rotating shaft 11 is rotatably connected to the sealing plate 10. A first handle 15 is fixedly connected to the side end of the first rotating shaft 11 to facilitate rotation of the first rotating shaft 11. A regular hexagonal column 16 is fixedly connected to the side end of the first handle 15 to facilitate rotation of the first handle 15 using an electric wrench. A first bevel gear 12 is fixedly connected to one end of the first rotating shaft 11 that extends into the groove 6. Two second bevel gears 13 that mesh with the first bevel gear 12 are provided inside the groove 6. A second rotating shaft 14 is fixedly connected to the side end of each of the two second bevel gears 13. The second rotating shaft 14 is fixedly connected to the corresponding first screw 9. Two fixing seats 27 are fixedly installed inside the groove 6. The two fixing seats 27 are rotatably connected to the two second rotating shafts 14 respectively to ensure stable rotation of the second rotating shafts 14 inside the groove 6.

[0030] Specifically, the four pins 4 on the connecting bracket 1 are inserted into the four slots 3 on the lower connecting bracket 1. Then, the first rotating shaft 11 is rotated, which drives the first bevel gear 12 to rotate. The first bevel gear 12 drives the two second bevel gears 13 to rotate, and the two second bevel gears 13 drive the corresponding second rotating shaft 14 and the first screw 9 to rotate. The rotation of the first screw 9 causes the square post 8 to move closer to the pin 4 and insert it into the slot 5, thereby fixing the pin 4 inside the slot 3, thus connecting the two connecting brackets. The connecting frame 1 is fixedly connected together, which avoids the need to use multiple bolts to install the connecting frame 1, saving time and improving the efficiency of tower crane tower body construction. The first rotating shaft 11 is fixedly connected to the side end of the first rotating shaft 11, and the first rotating shaft 11 is fixedly connected to the side end of the first rotating shaft 15. People put the sleeve of the electric wrench on the outside of the regular hexagonal column 16, and drive the regular hexagonal column 16, the first rotating shaft 11 and the first bevel gear 12 to rotate through the electric wrench, which facilitates the quick adjustment of the position of the corresponding two square columns 8, saving manpower.

[0031] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 A rain cover 17 is fixedly connected to the side end of the sealing plate 10. The rain cover 17 covers the outside of the first throttle 15 to prevent rainwater from falling on the first throttle 15. A sliding groove 18 is provided on the rain cover 17. A sliding plate 19 is slidably arranged inside the sliding groove 18. A second screw 20 is fixedly connected to the bottom end of the sliding plate 19. A fixing plate 21 is fixedly connected to the bottom end of the rain cover 17. The second screw 20 is rotatably connected to the fixing plate 21. A connecting plate 22 is fixedly connected to the top end of the sliding plate 19. A locking post 23 is provided on the connecting plate 22. The locking post 23 is slidably engaged with the rain cover 17. A plurality of fixing grooves 24 that are adapted to the locking post 23 are evenly arranged on the outside of the first throttle 15 to facilitate the fixing of the first throttle 15, the first rotating shaft 11 and the first bevel gear 12. A second throttle 25 is fixedly connected to the bottom end of the second screw 20 to facilitate the rotation of the second screw 20.

[0032] Specifically, by rotating the second screw 20, the slide plate 19 slides inside the sliding groove 18. The slide plate 19 drives the connecting plate 22 and the locking post 23 to move, so that the locking post 23 is inserted into the fixing groove 24 on the upper side of the first throttle 15. During the operation of the tower crane, the first throttle 15 is prevented from rotating by itself, ensuring the firmness of the connection between the two adjacent connecting frames 1.

[0033] In summary, when using the overall equipment:

[0034] Insert the four pins 4 on the connecting frame 1 into the four slots 3 on the lower connecting frame 1, and then rotate the first rotating shaft 11. The first rotating shaft 11 drives the first bevel gear 12 to rotate, and the first bevel gear 12 drives the two second bevel gears 13 to rotate. The two second bevel gears 13 drive the corresponding second rotating shaft 14 and the first screw 9 to rotate. The rotation of the first screw 9 causes the square post 8 to move towards the side closer to the pin 4 and insert the square post 8 into the slot 5, thereby fixing the pin 4 inside the slot 3 and thus fixing the two connecting frames 1 together. Rotate the second screw 20, and the second screw 20 causes the slide plate 19 to slide inside the sliding groove 18. The slide plate 19 drives the connecting plate 22 and the slot 23 to move, so that the slot 23 is inserted into the fixing groove 24 on the upper side of the first throttle 15 and the first throttle 15 is fixed. In this way, multiple connecting frames 1 are fixedly connected together.
