Description

Technical Field

[0001] This invention relates to the field of pipeline hoisting technology, and in particular to an auxiliary positioning mechanism for pipeline hoisting applied in water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. When carrying out water pipeline hoisting operations, the work is mostly carried out through scaffolding, and the pipeline is usually tied and fixed by traction ropes during the hoisting process.

[0003] However, with current traditional auxiliary positioning mechanisms, the limited assembly precision of the lifting frame necessitates multiple alignment and calibration of the pipe connection positions during pipe hoisting operations. This process is time-consuming, and pipe swaying during alignment and calibration can easily cause collisions and damage. Furthermore, existing traditional auxiliary positioning mechanisms often have gaps at the top of the slings used to lift the pipes, causing the supporting force to be mainly distributed on the lower half of the pipe, while the upper side has some freedom. This prevents complete locking of the pipe, resulting in significant swaying during hoisting, inaccurate positioning during pipe connections, and poor stability. Summary of the Invention

[0004] In view of this, the present invention provides a pipeline hoisting auxiliary positioning mechanism for water conservancy projects, which has a driving mechanism and an adjusting mechanism. The driving mechanism can move left and right with high precision inside the installation mechanism, so that the pipeline to be installed can be quickly and accurately aligned with the installed pipeline. At the same time, the lifting component can be used to tighten the sling body, reduce the gap between the sling body and the pipeline, reduce the sway amplitude of the sling body and the pipeline during hoisting and transportation, and improve the stability of hoisting and transportation.

[0005] This invention provides an auxiliary positioning mechanism for pipeline hoisting in water conservancy projects, specifically comprising: an installation mechanism; a drive mechanism installed inside the installation mechanism, with the moving wheel of the drive mechanism inserted into the guide rail of the installation mechanism; an adjustment mechanism installed on the left side of the drive mechanism, with the fixing component of the adjustment mechanism fixedly connected to the mounting groove of the control component of the drive mechanism by screws; a hoisting mechanism installed on the right side of the drive mechanism, with the hoisting mechanism's sling roller connected to the outside of the drive mechanism's rotating roller; two sets of sling bodies of the hoisting mechanism passing through the through holes of the lifting component and the guide plate, respectively; and a drive motor on the left side of the control component connected to the rotating component of the adjustment mechanism.

[0006] Optionally, a caster wheel is fixedly connected to the bottom of the mounting bracket by screws; a guide rail is fixedly connected to the inside of the mounting bracket by screws, and a guide groove is provided inside the guide rail.

[0007] Optionally, the control component has three drive motors inside, and the drive motors on the front and rear sides of the control component are respectively connected to gear sets; two control motors are installed inside the control component; a mounting slot is provided on the left side of the control component; and a guide roller is fixedly connected to the top of the control component by screws.

[0008] Optionally, two rotating rollers are fixedly connected to the right side of the control component by screws, and the rotating rollers are connected to the gear set of the control component through a rotating shaft.

[0009] Optionally, the left and right sides of the control component are each connected to three movable wheels via a rotating shaft, and the two movable wheels on the right side are connected to the control motor of the control component; a guide plate is fixedly connected to the right side of the control component by screws, and the guide plate has a through hole inside.

[0010] Optionally, the fixing member has a sliding groove inside and a rotating hole on the right side; a rotating member is inserted into the rotating hole of the rear fixing member, and the rotating member is a threaded rod.

[0011] Optionally, a guide rod is inserted into the rotating hole of the front-end fixing member; the adjustment mechanism further includes: a lifting member, with sliders on both the front and rear sides of the lifting member, and the sliders of the lifting member are inserted into the groove of the fixing member; the lifting member has a through hole inside, and two screw holes are opened on the right side of the lifting member; a rotating member is inserted into the screw hole at the front end of the lifting member, and a guide rod is inserted into the screw hole at the rear end of the lifting member.

[0012] Optionally, the sling body is wound around the outside of the sling roller.

[0013] Optionally, an auxiliary component is fixedly connected to the end of the sling body, and a rotating groove is provided inside the auxiliary component; an auxiliary wheel is rotatably connected inside the rotating groove of the auxiliary component.

[0014] Beneficial effects

[0015] According to various embodiments of the present invention, the auxiliary positioning mechanism, compared with the traditional auxiliary positioning mechanism, can make the drive mechanism as a whole finely adjusted left and right at the upper end of the mounting bracket through the control component. At the same time, the mounting bracket can quickly align the pipe to be installed with the installed pipe after the pipe is hoisted by moving the universal wheels, so as to make its positioning more accurate.

[0016] In addition, the rotating roller drives the sling roller to rotate, thereby causing the sling body to retract and extend. Since the left and right sling bodies are driven by two drive motors of the control unit respectively, the length of the left and right sling bodies can be adjusted independently, so that the left and right ends of the pipe can be stably kept horizontal. At the same time, the lifting component moves up and down under the drive of the rotating component. When the lifting component moves to the lower end, it will gradually tighten the left sling body, reduce the gap between the sling body and the pipe, make the pipe fixation more stable, reduce the sway of the sling body and the pipe during hoisting and transportation, improve the stability of hoisting and transportation, make the pipe connection more stable and accurate, and improve work efficiency.

[0017] In addition, when the pipe is placed inside the end of the sling body, the pipe will come into contact with the auxiliary wheel. The auxiliary wheel can effectively reduce the friction between the sling body and the pipe, making it easier and faster to put the pipe into the device, thus improving work efficiency.
