Description

Technical Field

[0001] The present invention relates to the field of highway tunnel construction, and specifically to an automatic steel bar hanging cloth trolley and its method. Background Technique

[0002] With the continuous development of China's economy, the road network system has been continuously constructed and improved, and the construction of highway and railway tunnels has also been increasing day by day. However, with the continuous aggravation of the aging population, tunnel construction is faced with a series of adverse factors such as high labor costs, high risks, and poor environments. The drill and blast method is currently the main construction method for mountain tunnels, in which dozens of mechanical equipment are used. With the continuous development of the equipment, most processes have achieved mechanized or even automated construction. However, due to the complex construction environment and many influencing factors in the construction of the secondary lining steel bars, it is basically mainly manual construction supplemented by machinery. Since dragging steel bars requires multiple people to cooperate at the same time, especially in high-altitude areas, the manual labor intensity is too high, the labor cost is getting higher and higher, and the construction efficiency is low.

[0003] Currently, the common steel bar hanging cloth trolleys on the market mainly have the following three types: The first type is the frame type welded on the construction site, with a walking mechanism and a lifting device added to the frame. Manual feeding and binding of steel bars are mainly used, and the hanging cloth is also manually laid. This type of equipment has a low cost, but a high manual labor intensity and a high labor cost; the second type is the frame type hanging cloth steel bar trolley mainly for automatic laying of hanging cloth and supplemented by steel bars launched by each equipment manufacturer, which solves the problem of automatic laying of circumferential hanging cloth. However, the steel bar binding is still mainly manual binding, and at most a lifting device or a jacking device is added to assist in the steel bar binding. This type of equipment cannot perform automatic feeding of steel bars and has a relatively single function; the third type is based on the structure of the second type of equipment, with a circumferential track that can be flipped close to the ground added at the end, which can assist in the feeding of circumferential steel bars, and then the circumferential track is translated. This structure solves the problem of manual feeding of steel bars, but since it occupies the traffic passage during feeding, the overall working efficiency is low and does not meet the requirements of the actual construction conditions on the construction site; this equipment optimizes the structure on the basis of the third type of equipment, adopts a form of 60-degree inclination of the ring track, automatic feeding of circumferential steel bars from the side, and automatic jacking at the top, which solves the problem that the circumferential feeding track occupies the construction passage and requires manual feeding, and integrates the function of automatic laying of hanging cloth. The equipment has a high degree of automation, a high feeding efficiency, can effectively reduce the manual construction intensity, and improve the construction efficiency. Summary of the Invention

[0046] Please refer to the attached Figure 1 - attached Figure 3 The embodiment of the present invention provides a method for using an automatic steel bar cloth hanging trolley. When the trolley works, the driving walking device 2-1 drives the trolley to move to a specified position in the tunnel through the electrical control system 7-1, and then drives the lifting oil cylinder 6-2 through the hydraulic pump station 6-1 to adjust the overall height of the equipment. After reaching the specified height, it stops. The hydraulic pump station 6-1 drives the rotating device 3-4 to make the fixed frame 3-1 form an angle of 60° with the vertical plane. Subsequently, the personnel on the tunnel ground send the connected steel bars into the driving trolley 3-2 through the ground guide and the electric hoist 4-1. After fixing with the fixed clamp block, the driving trolley 3-2 drags the steel bars along the track direction to the other side. The rotating device 3-4 makes the fixed frame 3-1 return to the vertical state, and then the transverse reduction motor driven by the loop track mechanism 3 drives the fixed frame 3-1 to move horizontally to the specified position. The steel bars are jacked up to the installation position by the telescopic oil cylinder 3-3, and the operators carry out the steel bar binding operation. After the binding is completed, the telescopic oil cylinder 3-3 retracts the steel bar support structure, and the loop track mechanism 3 is driven again to move to the end position, completing an automatic steel bar loading cycle operation. By replacing the clamping mechanism in the driving trolley 3-2, the installation function of the longitudinal steel bars and the waterproof board cloth hanging can be realized. Position sensors are installed in many places on the equipment to ensure the safety and reliability of the operation process.

[0047] Working principle: When the trolley is working, the driving and traveling device 2-1 drives the trolley to move to the specified position in the tunnel through the electrical control system 7-1. Then, the hydraulic pump station 6-1 drives the lifting cylinder 6-2 to adjust the overall height of the equipment. After reaching the specified height, it stops. Then, the hydraulic pump station 6-1 drives the rotating device 3-4 to make the fixed frame 3-1 form an angle of 60° with the vertical plane. Then, the personnel on the tunnel ground send the connected steel bars into the driving trolley 3-2 through the ground guide and the electric hoist 4-1. After being fixed by the fixed clamp block, the driving trolley 3-2 drags the steel bars forward along the track direction. After dragging the steel bars to the other side, the rotating device 3-4 makes the fixed frame 3-1 vertical. Then, the transverse deceleration motor carried by the loop track mechanism 3 drives the loop track mechanism 3 to move horizontally to meet the needs of different positions. When reaching the required position, the movement stops. The telescopic cylinder 3-3 jacks up the steel bars fixed on the fixed frame 3-1 to the installation position, and then manual steel bar binding operation is carried out. After the binding is completed, the steel bar support structure is retracted by the telescopic cylinder 3-3. Then, the transverse deceleration motor carried by the loop track mechanism 3 drives the loop track mechanism 3 to move horizontally to the end, thus completing an automatic steel bar loading cycle operation. By replacing the clamping mechanism in the driving trolley 3-2, the installation functions of longitudinal steel bars and waterproof board hanging cloth can be realized. Position sensors are installed in many places of the equipment to ensure the safety and reliability of the equipment operation.
