Description

Technical Field

[0001] This utility model relates to the field of landscaping technology, specifically a portable pipe lifting device for building installation. Background Technology

[0002] Pipeline installation is a crucial part of building installation projects. With the continuous expansion of building scale, both civil and industrial buildings involve a large number of pipelines, including water supply and drainage pipelines, fire protection pipelines, ventilation pipelines, and other types, with varying diameters, lengths, and weights.

[0003] In the prior art, such as the pipe installation and lifting device for building installation engineering proposed in patent application number "CN202322874553.7", the patent mainly uses the upward moving block of the worker to drive the sliding block to move upward in the sliding groove, and at the same time drive the connecting block and the adjusting plate to move the pipe upward. The worker places the pipe in the lower clamping plate and moves the pipe up and down by moving the worker moving block so that the worker can install the pipe.

[0004] However, the equipment in the aforementioned patent application lacks flexible steering capabilities and is difficult to adjust its angle in narrow spaces. This makes it impossible to lift the pipeline from different angles in some construction sites with complex building structures and limited space, affecting construction progress and efficiency. Furthermore, it lacks precision and versatility for pipelines of different lengths and cannot securely clamp pipelines of various specifications, which can easily lead to safety accidents such as pipeline slippage during the lifting process. Utility Model Content

[0005] The purpose of this invention is to provide a portable pipe lifting device for building installation, so as to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A portable pipe lifting device for building installation includes a base frame. A disc is fixedly mounted on the upper surface of the base frame. A main gear and a drive gear are rotated near the center of the upper surface of the disc via a shaft, and the drive gear and the main gear are meshed with each other. A motor is mounted on the bottom surface of the base frame, and the output end of the motor is connected to the drive gear. A connecting shaft is fixedly connected to the upper surface of the main gear. A lifting frame is fixedly connected to the end of the connecting shaft away from the main gear. Limiting blocks are fixedly connected to the bottom surface of the lifting frame near both sides. A circular groove is formed on the upper surface of the disc, and the bottom end of the limiting block is movably installed inside the circular groove.

[0008] Preferably, the lifting frame has first guide rails on both inner side walls, and a lifting frame is movably connected between the two first guide rails. A hydraulic telescopic rod is installed on the upper surface of the lifting frame near the center, and the upper end of the hydraulic telescopic rod is fixedly connected to the lifting frame.

[0009] Preferably, a support plate is fixedly connected between the two inner side walls of the lifting frame and near the bottom. Two second guide rails are provided on the outer side wall of the support plate. A clamping member is slidably connected inside each of the two second guide rails. An installation plate is fixedly connected to the outer side wall of the support plate and between the two second guide rails. Electric telescopic rods are fixedly connected to both sides of the installation plate. The ends of the two electric telescopic rods away from the installation plate are respectively fixedly connected to the two clamping members.

[0010] Preferably, the outer wall of the support plate is fixedly connected with diagonal bracing rods near both ends, and the outer wall of the clamping member is fixedly connected with an anti-slip pad.

[0011] Preferably, rollers are installed on the bottom surface of the base frame and near the four corners, and push handles are fixedly installed on both outer side walls of the base frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses a motor to drive the main gear and the drive gear to mesh, which drives the connecting shaft and the lifting frame to rotate. With the movement of the limit block in the circular slide groove, 360° rotation can be achieved, which facilitates the lifting of the pipeline from different angles. Even in narrow spaces, the lifting angle can be flexibly adjusted to meet the needs of complex construction environments.

[0015] 2. This utility model uses two second guide rails set on the support plate, combined with an electric telescopic rod to precisely control the position of the clamping parts.
