Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an automatic lifting and installation device for a concrete pipe. 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] In the field of municipal roads, the installation process of shafts, blind pipes, and inspection wells is that the concrete pipe itself is a rigid material. According to statistics, the most favorable lifting and installation method is vertical lifting and installation, and the vertical lifting and installation process is statistically compared. The most favorable method is to support and lift the concrete pipe inner diameter to install, which is not easy to damage the finished material.

[0004] Traditionally, horizontal concrete pipes use pipe unloaders, which can quickly complete installation and hoisting. However, for vertical shaft installation, there is no better hoisting and disassembly device. Traditionally, slings are usually used to tie up the vertical shaft. If the concrete quality is defective, the concrete pipe is easily crushed. Summary of the invention

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

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

[0007] A device for automatically lifting and installing a concrete pipe comprises a support pipe, wherein a mounting ring is sleeved on the support pipe, and the mounting ring is fixed on the outer wall of the support pipe, and a plurality of horizontal limit guide beams are arranged on the mounting ring, and one end of the horizontal limit guide beams is vertically fixed to the outer wall of the mounting ring; a lifting guide beam is arranged in each of the horizontal limit guide beams, and the lifting guide beams can move and be fixed in the horizontal limit guide beams, and a tensioning chain is connected to the top of the lifting guide beam, and the tensioning chain is fixed to the outer wall of the support pipe. Traditionally, horizontal concrete pipes use pipe unloaders, which can quickly complete installation and hoisting. However, for shaft installation, there is no better hoisting and disassembly device so far. Traditionally, slings are usually used to bind the shaft, and if the concrete quality is defective, the concrete pipe is easily crushed. In order to solve the above problems, this scheme designs an automatic lifting and installation device for concrete pipes, including a support pipe, a mounting ring is sleeved on the support pipe, and the mounting ring is fixed on the outer wall of the support pipe, a plurality of horizontal limit guide beams are arranged on the mounting ring, and one end of the horizontal limit guide beams is vertically fixed to the outer wall of the mounting ring, and the horizontal limit guide beams are used to change the working distance of the device, so that concrete pipes of different diameters can be lifted, and a lifting guide beam is arranged in the horizontal limit guide beam, and the lifting guide beam can be moved and fixed in the horizontal limit guide beam, and the top of the lifting guide beam is connected to a tensioning chain, and the tensioning chain is fixed to the outer wall of the support pipe. The lifting guide beam and the support pipe can be connected by the tensioning chain, and the tensioning chain is connected to the top of the lifting guide beam. When the lifting guide beam is working, the applied force can make the bottom end of the lifting guide beam tend to move outward, so that it can be stuck more tightly with the inner wall of the concrete pipe. This application can provide effective vertical transportation, vertical installation, and automatic hooking methods, meet most of the vertical transportation and vertical installation methods of concrete pipes, and effectively improve construction efficiency.

By utilizing the variable diameter of the retaining ring, the lower support tube can be fixed in the upper support tube without damaging the tube wall by drilling.

[0010] Furthermore, a locking arm is provided on the outer wall of the upper support tube, one end of the locking arm is connected to the outer wall of the upper support tube, and the other end is located below the retaining ring and contacts the bottom of the retaining ring. Through the locking arm, the lower support tube is fixed in the upper support tube under the action of gravity, and the larger end surface of the bottom of the retaining ring and the locking arm are used for locking and fixing.

[0022] The present invention and the field of municipal and temporary engineering construction technology are specifically aimed at the lifting and installation of municipal road shafts, blind pipes, inspection wells, etc. Figure 1 As shown, an automatic lifting and installation device for concrete pipes in this embodiment includes a support pipe, and the support pipe includes an upper support pipe 2 and a lower support pipe 9. A lifting ring 1 is installed on the top of the upper support pipe 2, and the top of the lower support pipe 9 is inserted into the bottom of the upper support pipe 2, and the lower support pipe 9 can move in the upper support pipe 2. The lifting ring is used to connect with the lifting equipment, and the support pipe is designed to be disassembled in two sections for easy assembly and storage. A mounting ring 12 is sleeved on the outer wall of the bottom of the lower support pipe 9, and the mounting ring 12 is fixed on the outer wall of the lower support pipe 9. Three horizontal limit guide beams 10 are arranged on the mounting ring 12, and one end of the horizontal limit guide beams 10 is vertically fixed to the outer wall of the mounting ring 12, and the adjacent horizontal limit guide beams 10 form an angle of 120°. The horizontal limit guide beams 10 are used to change the working distance of the device, and can lift concrete pipes of different diameters.

[0023] A lifting guide beam 8 is provided in each horizontal limit guide beam 10, and the lifting guide beam 8 can move and be fixed in the horizontal limit guide beam 10. A tension chain 5 is connected to the top of the lifting guide beam 8. Three mounting plates 13 are fixed on the outer wall of the upper support tube 2. The mounting plates 13 are evenly arranged around the axis of the upper support tube 2. Each tension chain 5 is fixed to a mounting plate 13. In this way, the tension chain 5 can be tightened to fix the horizontal limit guide beam 10 after the position is adjusted in place, and it can also play a protective role in preventing the lower part from slipping. The tension chain 5 adopts a steel chain, and the lifting guide beam 8 and the support tube can be connected by the tension chain 5. Moreover, the tension chain 5 is connected to the top of the lifting guide beam 8. When the lifting guide beam 8 is working, the applied force can make the bottom end of the lifting guide beam 8 tend to move outward, so that it can be more tightly stuck with the inner wall of the concrete pipe. This solution can provide effective vertical transportation, vertical installation, and automatic towing hook methods, meet most of the vertical transportation and vertical installation methods of concrete pipes, and effectively improve construction efficiency.

[0024] A trumpet-shaped retaining ring 7 is sleeved on the outer wall of the lower support tube 9, and the retaining ring 7 is fixed on the outer wall of the lower support tube 9, and the end with a smaller end face faces the upper support tube 2. The retaining ring 7 is located above the mounting ring 12. By utilizing the variable diameter of the retaining ring 7, the lower support tube 9 can be fixed in the upper support tube 2 without drilling or damaging the tube wall, thereby ensuring the force stability and service life of the support tube.

[0025] The outer wall of the upper support tube 2 is provided with a locking arm 6, and three mounting plates 2 4 are provided on the outer wall of the upper support tube 2. The mounting plates 2 4 are evenly fixed on the outer wall of the upper support tube 2 around the axis of the upper support tube 2. Each locking arm 6 is connected to a corresponding mounting plate 2 4, and can be fixed after adjusting the angle. The other end of the locking arm 6 is located below the retaining ring 7 and contacts the bottom of the retaining ring 7. Through the locking arm 6, under the action of gravity, the lower support tube 2 is fixed in the upper support tube, and it uses the larger end surface at the bottom of the retaining ring 7 and the locking arm 6 for locking and fixing.

[0026] In order to prevent sliding, a locking groove is provided on the wall surface where the locking arm 6 and the retaining ring 7 contact. The locking groove can increase the friction force, so that the retaining ring 7 can be firmly locked on the wall surface of the locking arm 6 to prevent sliding. The outer wall of the lifting guide beam 8 is concave to form a plurality of anti-skid grooves. The anti-skid groove can effectively contact with the concrete pipe, so that it can be installed vertically to improve the construction efficiency.

[0028] The vertical steel pipe is composed of two sections, in which the upper support pipe 2 adopts a steel pipe with an inner diameter of φ48.3, and the outer diameter of the lower support pipe 9 is slightly smaller than φ48.3, so that it can be embedded. The locking arm 6 is a U-shaped structure, and three groups of locking arms 6 are arranged around the upper support pipe 2, evenly and symmetrically arranged at 120°. A steel lock mouth is set at the end of the U-shaped locking arm 6, and the steel lock mouth effectively engages and locks with the conical guard ring to prevent the concrete pipe from falling. The lifting guide beam is an L-shaped structure, which is arranged around the lower support pipe 9 in three groups, evenly and symmetrically arranged at 120°, one end is connected in series with the upper tension chain 5, and the other end is provided with a steel lock mouth, which effectively contacts the concrete pipe, so that it can be installed vertically to improve construction efficiency. Three groups of horizontal limit guide beams are arranged around the lower support pipe 9, evenly and symmetrically arranged at 120°, and the locking holes 11 are evenly arranged along the outer diameter direction of the guide beam for locking and limiting, which can effectively control the vertical installation of concrete pipes of 300-800mm.

[0029] This solution improves construction efficiency, with simple operation, automatic hoisting, automatic hook and other high flexibility, thus ensuring the vertical installation of concrete pipes and quality control of finished materials. It also has a wide range of uses.
