Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a construction hoisting device. Background Art

[0002] During the construction process, it is often necessary to use a crane to hoist materials so that the construction materials can be hoisted to a high place for construction. For materials with smooth outer walls such as pipes and fan blades, corresponding hoists are required to position them to prevent them from sliding during the hoisting process and affecting safety.

[0003] After searching, the existing Chinese patent with publication number CN202320870167.8 discloses a construction hoist, which drives the rotating worm, worm wheel, first threaded rod and second threaded rod to rotate through the output end of the motor. The rotation of the first threaded rod and the second threaded rod can drive the two movable plates, the limit blocks and the clamping blocks to move relative to each other. The two clamping blocks can clamp the construction pipes, thereby ensuring the stability of the construction pipes during the lifting process. The self-locking property of the worm wheel can ensure the stability of the clamping of the construction pipes, thereby avoiding detachment during the lifting process.

[0004] The above technical solution has the following defects: although such a construction hoist structure can position the pipeline through the clamping block driven by the motor, thereby preventing it from slipping and falling during the lifting process, thereby improving safety, in actual use, it can only clamp and position one group of pipelines. When transporting multiple groups of pipelines, multiple lifting operations are required, which is inefficient. For this reason, a construction hoist is proposed, which can load multiple pipelines for lifting and transportation. A clamping assembly is provided to stably clamp both ends of the pipeline, so that the construction pipeline is more stable during lifting to prevent sliding, and the clamping distance can be adjusted according to the length of the pipeline, so that it can be suitable for lifting construction pipelines of different lengths.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

The clamping distance can be adjusted according to the length of the pipe, so that it can be suitable for hoisting construction pipes of different lengths.

[0008] The utility model solves the above-mentioned technical problems as follows: A construction hoist comprises a hoist base, a steel cable, and a hanging beam, the top of the hoist base is fixedly connected with a guardrail, the guardrail is fixedly connected with a support beam, the top of the support beam is fixedly connected with a No. 1 lifting ring, the bottom of the hanging beam is fixedly connected with a No. 2 lifting ring, the No. 1 lifting ring is connected through the steel cable No. 2 lifting ring, the top of the hanging beam is fixedly connected with a main lifting ring, the inner wall of the hoist base is fixedly connected with a brake stepper motor, the brake stepper motor is fixedly connected with a bidirectional lead screw, the outer wall of the bidirectional lead screw is threadedly connected with a lead screw nut, both sides of the lead screw nut are fixedly connected with a limit slider, both sides of the inner wall of the hoist base are fixedly connected with a limit rod, the limit slider is fixedly connected with an adjustment plate, the adjustment plate is fixedly connected with a clamping plate, and one side of the clamping plate is provided with an opening and closing door.
