Description

Technical Field

[0001] The invention relates to the technical field of municipal construction, in particular to a quick-installation vertical hoisting device. Background Art

[0002] Municipal engineering refers to the construction of municipal facilities. Municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (villages) and provide paid or free public products and services to residents based on government responsibilities and obligations. Municipal infrastructure projects refer to the civil engineering, pipeline, and equipment installation projects of urban roads, public transportation, water supply, drainage, gas, heat, gardening, sanitation, sewage treatment, garbage disposal, flood control, underground public facilities and ancillary facilities.

[0003] The roads within the urban area are municipal roads, which serve the internal system of the city and are also called municipal roads. Municipal roads need to consider the layout of urban pipelines (sewage pipes, wire and cable pipes, water and gas supply pipes, etc.), urban green belts, bicycle lanes, etc.

[0004] In the field of municipal roads, such as blind pipe installation, well point dewatering installation, inspection well installation, loading and unloading processes, etc., traditional methods such as manual handling or mechanical equipment turnover are used. For example, it is not recommended to use traditional methods for narrow construction access roads, which can easily cause operator fatigue and reduce construction efficiency. Summary of the invention

[0005] The purpose of the present invention is to overcome the problems raised in the above-mentioned background technology and to provide a quick-installation vertical lifting device, which provides effective vertical transportation, vertical installation, and automatic towing hook methods, meets the vertical transportation and vertical installation methods of most circular components, and effectively improves construction efficiency.

[0006] The purpose of the present invention is mainly achieved through the following technical solutions:

[0007] A quick-install vertical lifting device includes a base, a support column is arranged on the base, and the bottom of the support column is vertically fixed on the base, a top support plate is sleeved on the support column, and the top support plate is located above the base and can move vertically along the axis of the support column; an elastic connector is arranged between the top support plate and the base, and the two ends of the elastic connector are respectively connected to the top support plate and the base, and the elastic connector is sleeved on the support column; a lifting arm is arranged between the top support plate and the base, and the lifting arm is connected to the top support plate and the base at the same time and can rotate around the connection. In the field of municipal roads, such as blind pipe installation, well point dewatering installation, inspection well installation, loading and unloading processes, etc., traditional methods such as manual handling or mechanical equipment turnover are used. For example, it is not recommended to use traditional methods for narrow construction access roads, which can easily cause operator fatigue and reduce construction efficiency. In order to solve the above problems, this scheme designs a quick-installation vertical lifting device, including a base, which is the main component used as the support of the device. The base is a disc-shaped structure, and a support column is arranged on the base, and the bottom of the support column is vertically fixed on the base. The support column is a hollow steel pipe, and a top support plate is sleeved on the support column, and the top support plate is located above the base and can move vertically along the axis of the support column. An elastic connector is arranged between the top support plate and the base, and the two ends of the elastic connector are respectively connected to the top support plate and the base, and the elastic connector is sleeved on the support column; a lifting arm is arranged between the top support plate and the base, and the lifting arm is connected to the top support plate and the base at the same time and can rotate around the connection. The movement of the top support plate changes the angle of the lifting arm, so that when the hoisting cement pipe is sleeved on the device, it can be pressed against the inner wall of the cement pipe by the changing angle of the lifting arm and will not fall off. This is very convenient for vertical transportation and vertical installation of circular components, and effectively improves construction efficiency.

[0008] Furthermore, a height limiting plate is mounted on the support column, and the height limiting plate is located above the top supporting plate and fixed to the outer wall of the support column. The height limiting plate limits the maximum distance that the top supporting plate can move upward, so as to prevent the top supporting plate from exceeding the limit and damaging the lower components.

[0009] Furthermore, the lifting arm includes a lifting guide beam and a diameter limiting guide beam, one end of the diameter limiting guide beam is connected to the base and can rotate around the connection, the other end of the diameter limiting guide beam is connected to the lifting guide beam and can rotate around the connection, and the end of the lifting guide beam away from the connection with the diameter limiting guide beam is connected to the top support plate and can rotate around the connection. The lifting guide beam and the diameter limiting guide beam rotate around their respective connections, and changing the angle of the lifting arm changes the size of the device. The position of the diameter limiting guide beam is used to clamp and fix cement pipes of different diameters for hoisting. The lifting guide beam and the diameter limiting guide beam work at a horizontal angle within the range of 0° to 90° for hoisting. When the hoisting angle is 0°, the hoisting pipe diameter is the maximum value. On the contrary, the vertical installation of 300-800mm concrete pipes can be effectively controlled.

[0010] In order to balance the force points, it is best to arrange the lifting arms on the base in a cross-shaped structure. This way, the contact can be balanced, the force is evenly distributed, and it is more stable.

[0011] Furthermore, the top support plate is provided with a plurality of through holes, and the through holes are evenly arranged around the center of the top support plate. The through holes are provided to reduce the weight of the top tray, and the top tray is arranged around the center so that the center of gravity can be stable and will not tilt during hoisting.

[0012] Furthermore, a spring base is provided on the top of the top support plate, the bottom of the elastic connector is fixed on the spring base, a spring top seat is fixed on the bottom of the top support plate, the top of the elastic connector is fixed on the spring top seat, and the support column passes through the spring base and the spring top seat at the same time. The spring seat is used to install the elastic connector, and the elastic connector preferably adopts a high-strength spring. This design allows the spring to always move in a straight line when in use.

[0013] In summary, the present invention has the following beneficial effects compared with the prior art:

[0014] (1) The present invention only requires one person to operate the entire transportation to the towing hook process, without the need for assistance, with high flexibility, which can easily improve construction efficiency and enhance technical innovation at the construction site;

[0015] (2) During the component positioning and installation process of the present invention, the device can be used for fine adjustment without the need for secondary lifting to achieve precise positioning. BRIEF DESCRIPTION OF THE DRAWINGS

The top support plate 4 is also a disc structure, and its size is the same as that of the base 10. A plurality of through holes 5 are arranged on the top support plate 4, and the through holes 5 are evenly arranged around the center of the top support plate 4. The through holes 5 are arranged to reduce the weight of the top support plate 4, and it is arranged around the center so that the center of gravity can be stable and will not tilt during lifting.

[0025] An elastic connector 8 is provided between the top support plate 4 and the base 10, and the two ends of the elastic connector 8 are connected to the top support plate 4 and the base 10 respectively. The elastic connector 8 is sleeved on the support column 2. The elastic connector 8 preferably adopts a high-strength spring. The high-strength spring is provided between the top support plate 4 and the base 10, so that it can play a compaction buffer or avoid forced contact between the upper component and the lower component when the component is lifted. A spring base 9 is provided on the top of the top support plate 4, and the bottom of the elastic connector 8 is fixed on the spring base 9. A spring top seat is fixed on the bottom of the top support plate 4, and the top of the elastic connector 8 is fixed on the spring top seat. The support column 2 passes through the spring base 9 and the spring top seat at the same time. The spring seat is used to install the elastic connector. This design allows the spring to always move in a straight line when in use.

[0026] A lifting arm is provided between the top supporting plate 4 and the base 10, and the lifting arm is connected to both the top supporting plate 4 and the base 10 and can rotate around the connection. In order to balance the force points, it is best to arrange the lifting arm on the base 10 in a cross-shaped structure. In this way, the contact can be balanced, the force is evenly distributed, and it is more stable. The top supporting plate moves to change the angle of the lifting arm, so that when the cement pipe is hoisted and sleeved on the device, it can be pressed against the inner wall of the cement pipe by the changed angle of the lifting arm and will not fall off. This is very convenient for vertical transportation and vertical installation of circular components, and effectively improves construction efficiency.

[0027] The lifting arm includes a lifting guide beam 6 and a diameter limiting guide beam 7. One end of the diameter limiting guide beam 7 is connected to the base 10 and can rotate around the connection.

The end of the lifting guide beam 6 away from the connection with the diameter limiting guide beam 7 is connected to the top support plate 4 and can rotate around the connection. The lifting guide beam 6 and the diameter limiting guide beam 7 rotate around their respective connections. Changing the angle of the lifting arm changes the size of the device. The position of the diameter limiting guide beam 7 is used to clamp and fix cement pipes of different diameters for hoisting. The lifting guide beam and the diameter limiting guide beam work at a horizontal angle within the range of 0° to 90° for hoisting. When the hoisting angle is 0°, the hoisting pipe diameter is the maximum value. On the contrary, the vertical installation of 300-800mm concrete pipes can be effectively controlled.

[0028] A height limiting plate 3 is placed on the support column 2, and the height limiting plate 3 is located above the top supporting plate 4 and fixed to the outer wall of the support column 2. The height limiting plate 3 limits the maximum distance that the top supporting plate 4 can move upward, and is welded 30 mm from the top of the top supporting plate 4 to prevent the top supporting plate 4 from exceeding the limit and damaging the lower components.
