Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, specifically relating to hoisting equipment for rainwater pipeline construction. Background Technology

[0002] During the construction of rainwater pipelines, hoisting operations are a crucial step, and their efficiency and safety directly affect the progress and quality of the entire project.

[0003] Traditional methods of rainwater pipe construction and transportation often rely on excavators for material handling. However, when excavators move on the ground, they are easily obstructed by various obstacles at the construction site, such as piled-up building materials, complex terrain, and other construction equipment. This not only makes it difficult for excavators to move, but also consumes a lot of time due to frequent route adjustments, severely reducing construction efficiency. At the same time, because traditional equipment lacks flexible lifting and rotation adjustment functions, it is difficult to meet the needs of rainwater pipe trenches of different depths and complex installation angles, making it difficult to guarantee construction accuracy and increasing the risk of errors and rework during the construction process. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing hoisting equipment for rainwater pipeline construction. The specific technical solution is as follows:

[0005] A hoisting device for rainwater pipe construction includes an electric trolley. A lifting component is fixed to the upper end of the electric trolley, and a rotary drive component is mounted on the lifting component. A central rod is provided at the output end of the rotary drive component, and a hanger is fixed to the upper end of the central rod. One end of the hanger is welded with a parallel support plate and a limiting frame. A concrete counterweight is installed in a hole in the limiting frame, and the lower end of the concrete counterweight contacts the upper surface of the support plate. Two electric hoists are installed at the other end of the hanger. Steel wire ropes are wound on the winding reels of the electric hoists, and hooks for hoisting rainwater pipes are fixed to the free ends of the steel wire ropes.

[0006] Preferably, the lifting component includes an electric push rod fixed to the upper end of the electric trolley, a tray fixed to the telescopic end of the electric push rod, two guide rods fixed to the lower surface of the tray, a guide block welded to the housing surface of the electric push rod, and the lower end of the guide rod movably installed in a hole opened on the surface of the guide block.

[0007] Preferably, the rotary drive component includes a bearing sleeve fixed to the upper surface of the tray, and the bearing sleeve is sleeved on the lower end of the central rod. A driven gear is fixed to the outer surface of the central rod, and a geared motor is fixed to the surface of the tray. A drive gear is fixed to the output shaft of the geared motor, and the drive gear meshes with the driven gear.

[0008] Preferably, a connecting plate is rotatably mounted on the surface of the central rod, and the free end of the connecting plate is rotatably mounted on the output shaft of the geared motor.

[0009] Preferably, a support wheel is mounted on the lower surface of the driven gear, a wheel groove is formed on the upper surface of the tray, and the lower end of the support wheel is located in the wheel groove.

[0010] Preferably, the ring array of support wheels has six parts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The electric trolley, equipped with a lifting mechanism, can move flexibly within the excavated rainwater pipe trench, solving the problem of excavators being difficult to move due to obstacles. The lifting mechanism also features a rotary drive unit, allowing it to move up and down on the trolley. The output of the rotary drive unit rotates the central rod, enabling the central rod to rotate and lift the hanger. One end of the hanger is fitted with a concrete counterweight via a support plate and limit frame. Two electric hoists at the other end, connected by wire ropes and hooks, are used to lift the rainwater pipes. The different lengths of the wire ropes on the two hoists allow for adjustable angles during pipe lifting, facilitating assembly after installation. This design allows the electric trolley to move freely within the rainwater pipe trench, reducing the cost associated with traditional excavator or truck crane installations for rainwater pipe lifting.

[0013] 2. A lifting device consisting of an electric push rod, a tray, a guide rod, and a guide block is used. The tray installed on the telescopic end of the electric push rod is used for lifting. The guide rod, which is fixed on the lower surface of the tray, is movably installed in the hole opened on the surface of the guide block welded to the surface of the electric push rod housing. This allows the guide rod and the guide block to cooperate to increase the stability of the electric push rod when the telescopic end lifts and lowers with the tray.

[0014] 3. A rotary drive component consisting of a bearing sleeve, a central rod, a driven gear, a geared motor, a drive gear, a connecting plate, a support wheel, and a wheel groove is used. The lower end of the central rod is installed inside the bearing sleeve, and the drive gear fixed to the output shaft of the geared motor meshes with the driven gear fixed to the outer surface of the central rod. This facilitates the geared motor to rotate the central rod through the drive gear and the driven gear, thereby achieving the purpose of rotating the central rod and the hanger. At the same time, the bearing sleeve and the geared motor are both installed on the upper surface of the pallet, so that the hanger can be raised and lowered when the pallet is raised and lowered. The lower end of the support wheel installed on the lower surface of the driven gear is set in the wheel groove opened on the upper surface of the pallet, which increases the stability of the driven gear during rotation, thereby improving the stability of the rainwater pipe during hoisting.

[0021] In this embodiment, a lifting device is installed on the electric trolley 1, which can move flexibly within the rainwater pipe trench excavated in the ground. This solves the problem that excavators are easily hindered by obstacles when moving on the ground. The rotating drive device installed on the lifting device facilitates the lifting of the lifting device while carrying the rotating drive device on the electric trolley 1. The output end of the rotating drive device rotates the center rod 7, thereby achieving the purpose of rotating and lifting the hanger 14 with the center rod 7. One end of the hanger 14 is equipped with a concrete counterweight block 17 for counterweight through a support plate 15 and a limit frame 16. Two electric hoists 18 are installed on the other end of the hanger 14 for lifting rainwater pipes through wire ropes 19 and hooks 20. This facilitates the movement of the electric trolley 1 within the rainwater pipe trench to lift the rainwater pipes, solving the problem of increased costs associated with traditional rainwater pipe lifting using excavators or truck cranes.

[0022] Specifically, the lifting component includes an electric push rod 2 fixed to the upper end of the electric trolley 1, a tray 3 fixed to the telescopic end of the electric push rod 2, two guide rods 4 fixed to the lower surface of the tray 3, a guide block 5 welded to the surface of the housing of the electric push rod 2, and the lower end of the guide rod 4 movably installed in a hole opened on the surface of the guide block 5.

[0023] In this embodiment, a lifting device consisting of an electric push rod 2, a tray 3, a guide rod 4, and a guide block 5 is used. The tray 3, which is installed on the telescopic end of the electric push rod 2, is used for lifting. The guide rod 4, which is fixed on the lower surface of the tray 3, is movably installed in the hole opened on the surface of the guide block 5 welded to the surface of the electric push rod 2 housing. This allows the guide rod 4 and the guide block 5 to cooperate to increase the stability of the electric push rod 2 when the telescopic end carries the tray 3 up and down.

[0024] Specifically, the rotary drive component includes a bearing sleeve 6 fixed to the upper surface of the tray 3, and the bearing sleeve 6 is fitted onto the lower end of the central rod 7.

A drive gear 10 is fixed to the output shaft of the geared motor 9, and the drive gear 10 meshes with the driven gear 8. A connecting plate 11 is rotatably mounted on the surface of the central rod 7, and the free end of the connecting plate 11 is rotatably mounted on the output shaft of the geared motor 9. A support wheel 12 is mounted on the lower surface of the driven gear 8. A wheel groove 13 is opened on the upper surface of the tray 3, and the lower end of the support wheel 12 is located in the wheel groove 13. There are six support wheels 12 in a circular array.

[0025] In this embodiment, a rotary drive component consisting of a bearing sleeve 6, a central rod 7, a driven gear 8, a reduction motor 9, a drive gear 10, a connecting plate 11, a support wheel 12, and a wheel groove 13 is used. The lower end of the central rod 7 is installed inside the bearing sleeve 6, and the drive gear 10, whose output shaft of the reduction motor 9 is fixed, meshes with the driven gear 8, which is fixed on the outer surface of the central rod 7. This facilitates the reduction motor 9 to rotate the central rod 7 through the drive gear 10 and the driven gear 8, thereby achieving the purpose of rotating the central rod 7 and the hanger 14. At the same time, the bearing sleeve 6 and the reduction motor 9 are both installed on the upper surface of the tray 3, so that the tray 3 can be raised and lowered along with the hanger 14. The lower end of the support wheel 12, which is installed on the lower surface of the driven gear 8, is set in the wheel groove 13 opened on the upper surface of the tray 3, which increases the stability of the driven gear 8 when rotating, thereby improving the stability of the rainwater pipe during installation.
