Description

Technical Field

[0001] The utility model relates to a special construction hoist for an elevator shaft. Background Art

[0002] At present, the shaft construction elevator is a special lifting equipment used for vertical transportation and construction work in the shaft, and is widely used in the construction industry. A Chinese patent with publication number CN1927688A discloses a formula gear rack construction elevator, which includes a frame, a cage, a counterweight, a wire rope, a beam and a sheave, etc. The beam is connected to the top of the frame, the sheave is connected to the beam, the wire rope is wound around the sheave and the two ends of the wire rope are respectively connected to the cage and the counterweight, and the counterweight can balance a part of the weight of the cage.

[0003] During the construction process, as the height of the building increases, the height of the frame also increases. The frame is built of standard sections. When the frame is raised, the top beam and the sky wheel need to be removed, and then a certain number of standard sections are installed on the top of the frame to increase the height of the frame. After the standard sections are installed, the beam and the sky wheel are reinstalled on the top of the frame. However, due to the limited length of the wire rope, the length of the wire rope is not enough after the frame is raised, so the cage and the counterweight cannot be connected. At this time, a longer wire rope needs to be replaced. During the entire construction process, the frame needs to be raised many times, and a longer wire rope needs to be replaced each time the frame is raised. Not only does it cause troublesome operation to replace the wire rope, but it also requires multiple wire ropes of different lengths, which increases the cost. Utility Model Content

[0054] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0055] like Figures 1 to 5 As shown, a special construction hoist for an elevator shaft, comprising:

[0056] Frame 1;

[0057] A cage 2, wherein the cage 2 is connected to a first guide assembly, wherein the first guide assembly cooperates with the frame 1 and is used to guide the cage 2 to move on the frame 1 in an up-down direction;

[0058] A counterweight 3, wherein the counterweight 3 is connected to a second guide assembly, and the second guide assembly cooperates with the frame 1 and is used to guide the counterweight 3 to move on the frame 1 in an up-down direction;

[0059] A lifting drive mechanism, which is installed between the frame 1 and the cage 2 and is used to drive the cage 2 to move up and down on the frame 1;

[0060] A guide wheel assembly 4, wherein the guide wheel assembly 4 is connected to the upper end of the frame 1;

[0061] A fixed roller 5, wherein the fixed roller 5 is rotatably connected to the cage 2;

[0062] A reel 6, wherein the reel 6 is mounted on the cage 2;

[0063] A steel wire rope 7, the steel wire rope 7 is wound on the drum 6 and is used to release at least a portion of the steel wire rope from the drum 6, the steel wire rope 7 released from the drum 6 is connected to the fixed roller 5, is wound around the guide wheel assembly 4, and then is connected to the counterweight 3;

[0064] The rope clamp 8 is used to clamp the two ends of the steel wire rope 7 wound around the fixed roller 5 so as to lock and fix the steel wire rope 7 to the fixed roller 5 .

[0065] Specifically, a part of the steel wire rope 7 is wound and stored on the drum 6, and another part of the steel wire rope 7 is released from the drum 6. The released steel wire rope 7 is connected to the fixed roller 5 through the rope clamp 8, and the steel wire rope 7 is also connected to the counterweight 3 after passing through the guide wheel assembly 4, and the fixed roller 5 is connected to the cage 2, so the gravity of the counterweight 3 is transmitted to the fixed roller 5 through the steel wire rope 7 and then to the cage 2 to form an upward pulling force, which can offset a part of the weight of the cage 2. When the lifting drive mechanism drives the cage 2 to move upward, the counterweight 3 will move downward.

[0066] Specifically, as the height of the building increases, the height of the frame 1 also increases accordingly. For example, when the building is built to the fifth floor, the height of the frame 1 only needs to reach the height of the fifth floor. When the building is built to the tenth floor, the frame 1 needs to be increased to the height of the tenth floor. When the frame 1 is raised, the guide wheel assembly 4 is removed, and then a certain number of standard sections are installed on the top of the frame 1 to increase the height of the frame 1. After the standard sections are installed, the guide wheel assembly 4 is reinstalled on the top of the frame 1. At this time, the length of the originally released wire rope 7 is not enough, and the rope clamp 8 needs to be opened and more wire rope 7 is released from the drum 6. After the length of the released wire rope 7 is sufficient, the wire rope 7 is reconnected to the fixed roller 5 and the two ends of the wire rope 7 wound on the fixed roller 5 are clamped by the rope clamp 8. After the rope clamp 8 is clamped, the wire rope 7 and the fixed roller 5 are reliably fixed and connected. At this time, the length of the released wire rope 7 is sufficient to reconnect the cage 2 with the counterweight 3. In this embodiment, after the height of the frame 1 is increased, it is not necessary to replace the steel wire rope 7, nor is it necessary to equip multiple steel wire ropes 7. Only one steel wire rope 7 is needed and the length of the steel wire rope 7 released from the drum 6 can be adjusted to adapt the steel wire rope 7 to the height of the frame 1, thereby avoiding the cumbersome operation of replacing the steel wire rope 7, making the operation more convenient, and saving the cost of purchasing the steel wire rope 7. In this embodiment, the rope clamp 8 can be a clamp head for the steel wire rope 7.

The screw 15 is provided with a forward thread that is threadedly connected to the first clamp 13 and a reverse thread that is threadedly connected to the second clamp 14. The screw 15 is used to drive the first clamp 13 and the second clamp 14 to move toward each other to clamp the anti-rotation ring 10 when rotating; specifically, the forward thread and the reverse thread have opposite rotation directions. Normally, the screw 15 is rotated to drive the first clamp 13 and the second clamp 14 to move toward each other and clamp the anti-rotation ring 10, thereby preventing the drum 6 from rotating, and thereby preventing the steel wire rope 7 on the drum 6 from accidentally falling off. When it is necessary to release or reel the steel wire rope 7, the screw 15 is rotated to drive the first clamp 13 and the second clamp 14 to move in opposite directions to loosen the anti-rotation ring 10, and at this time, the drum 6 can rotate and reel or release the steel wire rope 7.

When the lifting drive mechanism drives the cage 2 to move upward, the counterweight 3 will move downward. As the height of the building increases, the height of the frame 1 also increases. For example, when the building is built to the fifth floor, the height of the frame 1 only needs to reach the height of the fifth floor. When the building is built to the tenth floor, the frame 1 needs to be increased to the height of the tenth floor. When the frame 1 is raised, the guide wheel assembly 4 is removed, and then a certain number of standard sections are installed on the top of the frame 1 to increase the height of the frame 1. After the standard sections are installed, the guide wheel assembly 4 is reinstalled on the top of the frame 1.
