DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in the art without creative labor fall within the scope of protection of the utility model.

[0023] Please refer to Figs. 1 to 4This utility model provides a technical solution: a unitized curtain wall lifting cantilever ring track winch, including a base 1. Two hydraulic cylinders 5 are mounted on the top of the base 1. Each hydraulic cylinder 5 has an extension rod 6 at its output end. A hoisting assembly is positioned between the two extension rods 6. A lifting assembly is mounted on the top of the base 1. A connecting rod 2 is mounted at the rear end of the lifting assembly. A fixing frame 3 is mounted at the rear end of the connecting rod 2. A pushing assembly is mounted at the front end of the inner cavity of the fixing frame 3. A clamping plate 4 is mounted on the rear side of the pushing assembly. Through the lifting assembly, the fixing frame 3 can be fitted onto the edge railing of the roof. The pushing assembly pushes the clamping plate 4 towards the inner cavity of the fixing frame 3. The rear side of the cavity slides, allowing the clamping plate 4 to engage with the rear side of the inner wall of the fixing frame 3 to clamp and fix the guardrail, thereby achieving the fixation of the device. During the hoisting of the curtain wall, no counterweight is required to maintain balance, solving the problem that existing winches require a large amount of counterweight to maintain balance during the hoisting of the curtain wall, and the large number of counterweights makes the winch movement inconvenient. By setting the hydraulic cylinder 5, the height of the winding assembly can be reduced, thereby reducing the size of the device and facilitating its position movement. By setting the winding assembly, the length of the hoisting steel cable can be adjusted, thereby achieving the hoisting of the curtain wall.

[0024] In this embodiment, the hoisting assembly includes a first motor 7, a rotating column 8, and a take-up roller 9. The first motor 7 is located at the right end of the extension rod 6, and the output end of the first motor 7 extends between the two extension rods 6. One end of the rotating column 8 is rotatably connected to the right side of the other extension rod 6 through a bearing, and the other end of the rotating column 8 is fixedly connected to the output end of the first motor 7. The take-up roller 9 is fixedly sleeved on the outer wall of the rotating column 8, and a hoisting steel cable is fixedly connected to the outer wall of the take-up roller 9. When the first motor 7 is started, the first motor 7 drives the take-up roller 9 to rotate through the rotating column 8 to perform the take-up and unwinding operation of the steel cable, thereby realizing the hoisting of the curtain wall.

[0025] In this embodiment, baffles 10 are provided on both the left and right sides of the outer wall of the take-up roller 9. The baffles 10 can prevent the steel cable from getting tangled on the rotating column 8.

[0026] In this embodiment, the lifting assembly includes a guide rod 11, a top plate 12, a second motor 13, a lead screw 14, and a lifting plate 15. The guide rod 11 is located at the rear of the top of the base 1, the top plate 12 is located at the top of the base 1, the second motor 13 is located at the top of the top plate 12, and the output end of the second motor 13 extends to the bottom of the top plate 12. One end of the lead screw 14 is rotatably connected to the top of the base 1 through a bearing, and the other end of the lead screw 14 is fixedly connected to the output end of the second motor 13. The lifting plate 15 is screwed to the outer wall of the lead screw 14 and slidably sleeved on the outer wall of the guide rod 11. The lifting plate 15 is fixedly connected to the connecting rod 2. When the second motor 13 is started, it drives the lead screw 14 to rotate. Under the action of the rotational force of the thread on the outer wall of the lead screw 14, when the lead screw 14 rotates, the lifting plate 15 can slide downward along a straight line under the limiting action of the guide rod 11, so that the fixing frame 3 is sleeved on the roof railing.

[0027] In this embodiment, the pushing component includes a fixed cylinder 16, a screw 17, a knob 18, and a limiting component. The fixed cylinder 16 is fixedly inserted into the front end of the fixed frame 3, the screw 17 is screwed into the inner cavity of the fixed cylinder 16, the knob 18 is located at the front end of the screw 17, and the rear end of the screw 17 is rotatably connected to the clamping plate 4 through a bearing. The limiting component is located on the fixed frame 3 and is fixedly connected to the clamping plate 4. Rotating the knob 18 causes the screw 17 to rotate. Under the action of the rotational force of the screw 17's outer wall thread, when the screw 17 rotates, the clamping plate 4 can slide along a straight line towards the rear side of the inner cavity of the fixed frame 3 under the limiting action of the limiting component, so that the clamping plate 4 and the fixed frame 3 cooperate to clamp and fix the guardrail. During the hoisting of the curtain wall, no counterweight is needed to maintain balance, which solves the problem that the existing winch requires a large amount of counterweight to maintain balance during the hoisting of the curtain wall, and the large number of counterweights makes the winch difficult to move.

[0028] In this embodiment, the limiting component includes a telescopic cylinder 19, a telescopic rod 20, and a connecting component. The telescopic cylinder 19 is mounted on the fixed frame 3. The telescopic rod 20 is slidably inserted into the inner cavity of the telescopic cylinder 19 and fixedly connected to the clamping plate 4. The connecting component is mounted in the inner cavity of the telescopic cylinder 19 and fixedly connected to the outer wall of the telescopic rod 20. When the clamping plate 4 slides, the telescopic rod 20 can synchronously extend and retract within the inner cavity of the telescopic cylinder 19. Under the combined action of the telescopic rod 20 and the telescopic cylinder 19, the clamping plate 4 can be prevented from rotating with the screw 17 when the screw 17 rotates, and the clamping plate 4 can always slide back and forth along a straight line.

[0029] In this embodiment, the connecting component includes a connecting groove 21 and a connecting block 22. The connecting groove 21 is formed on the inner wall of the telescopic support. The connecting block 22 is slidably embedded in the inner cavity of the connecting groove 21 and fixedly connected to the outer wall of the telescopic rod 20. Under the combined action of the connecting block 22 and the connecting groove 21, one end of the telescopic rod 20 can always be inserted into the inner cavity of the telescopic cylinder 19, which improves the stability of the limiting component during use.

[0030] In this embodiment, the inner cavity of the connecting groove 21 and the outer wall of the connecting block 22 are adapted to each other and are both dovetail-shaped, which can keep one end of the connecting block 22 embedded in the inner cavity of the connecting groove 21, thus improving the stability of the connecting assembly during use.

[0031] In this embodiment, wheels are provided at the four corners of the bottom of the base 1, which facilitates the movement of the device and makes it easier to move the device to a different location, thus improving the convenience of the device in use.

[0032] In this embodiment, the wheels are self-locking swivel wheels.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
