TECHNICAL FIELD

[0001] The utility model relates to a tunnel construction technical field, especially a tunnel second lining reinforcement cage hoop reinforcement processing and conveying equipment. BACKGROUND

[0002] In the traditional tunnel construction, the feeding of reinforcement is mainly completed by manual work. However, the hoop reinforcement, as the main reinforcement of the tunnel reinforcement cage, has a large diameter and a long length, and its circumference reaches 20-38 meters (the diameter of the hoop reinforcement is generally about 18-25 mm, the length is 27 meters, and the weight is about 100 kg) after two or three butt joints on the ground. Such length and weight make the operation of the hoop reinforcement in the tunnel extremely difficult. In the construction process, about 10-12 people are needed to pull the hoop reinforcement. A 6-meter-long tunnel working unit has 60 hoop reinforcements in the inner and outer layers, and needs to be operated back and forth for 60 times. The working efficiency is low, and many people are needed. CONTENT OF THE UTILITY MODEL

[0003] In view of the problems existing in the prior art, the utility model aims to provide a tunnel second lining reinforcement cage hoop reinforcement processing and conveying equipment to solve the problem of difficult operation of the hoop reinforcement in the tunnel.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a tunnel second lining reinforcement cage hoop reinforcement processing and conveying equipment, which comprises a rack, and further comprises a splicing mechanism and a storage conveying mechanism installed on the rack. The splicing mechanism is used for splicing two or more reinforcements into a designed length. The storage conveying mechanism is used for storing and conveying the spliced reinforcement. The storage conveying mechanism comprises an upper platform and a lower platform. The upper platform is connected to the transmission end of the splicing mechanism. The upper platform comprises two horizontal supports arranged opposite to each other. The end of the horizontal supports close to each other is a free end. The opposite end of the left horizontal support is fixed to the rack, and the opposite end of the right horizontal support is hinged to the rack and supported and fixed by a second driving element. The second driving element can drive the right horizontal support to turn down to open the upper platform. When the upper platform is opened, the reinforcement on the upper platform can automatically fall into the lower platform. The lower platform comprises a guide rail extending forward and backward. The guide rail is installed on the rack. A guide rail support is slidably connected to the guide rail. A plurality of transverse rollers are arranged on the guide rail support in front of and behind each other. The transverse rollers correspond to the horizontal supports upward and downward.

[0005] In the above scheme: the splicing mechanism includes a first roller conveyor belt, a first linkage mechanism below the first roller conveyor belt, the first linkage mechanism being equipped with a first power mechanism, a second roller conveyor belt arranged side-by-side to the right of the first roller conveyor belt, a second linkage mechanism arranged to the right of the second roller conveyor belt, the second linkage mechanism being equipped with a second power mechanism, a third roller conveyor belt arranged side-by-side above the second roller conveyor belt, the third roller conveyor belt being extended rearward, and a third linkage mechanism arranged below the third roller conveyor belt, the third linkage mechanism being equipped with a third power mechanism; the first power mechanism can drive the first linkage mechanism to move, thereby flipping the steel bars on the first roller conveyor belt to the right onto the second roller conveyor belt; the second power mechanism can drive the second linkage mechanism to move, thereby flipping the steel bars on the second roller conveyor belt upward onto the third roller conveyor belt, two or more steel bars can be spliced ​​on the third roller conveyor belt through a sleeve, the third power mechanism can drive the third linkage mechanism to move, thereby flipping the spliced ​​steel bars onto the storage conveying mechanism. The third roller conveyor belt is extended to facilitate the splicing of steel bars. The steel bars come with connecting threads at the factory, and the sleeve connection can be completed manually or by setting up mechanical equipment.

[0006] In the above scheme: the end face milling device of the steel bar is evenly distributed in front and behind the first roller conveyor belt. The end face of the steel bar is milled flat first, and then the end connection is carried out, which helps to ensure the splicing effect of the steel bar.

[0007] In the above scheme: the third roller conveyor belt includes a conveyor belt body and an extension section arranged one in front of the other. Two floating vises spaced apart are arranged between the conveyor belt body and the extension section. The two floating vises can move towards each other. A sleeve clamping and torsion device is arranged between the two floating vises. When two reinforcing bars are clamped in the two floating vises respectively, and the ends of the two reinforcing bars that are close to each other are pre-connected to the two ends of the sleeve, the sleeve clamping and torsion device can clamp the sleeve and drive it to rotate, thereby realizing the splicing of the two reinforcing bars. This achieves automated splicing of the reinforcing bars. When the sleeve clamping and torsion device drives the sleeve to rotate, the two floating vises can move towards each other to ensure that the two reinforcing bars can be spliced ​​smoothly.

[0008] In the above scheme: the bottom of the frame is equipped with a walking device to facilitate the movement of the tunnel secondary lining steel cage circumferential steel reinforcement processing and conveying equipment.

[0009] The beneficial effects of this utility model are:

[0010] 1. The splicing mechanism can splice two or more steel bars into the designed length, which reduces the transportation cost and operation difficulty compared with splicing the steel bars in advance on the ground; 2. When the upper platform is opened, the steel bars thereon can automatically fall into the horizontal supporting roller, the horizontal supporting roller plays a supporting role and can also reduce the drawing resistance when the steel bars are subsequently drawn to the trolley, and the guide rail support can reciprocate on the guide rail, so as to convey the steel bars to the trolley position. In short, the tunnel inner ring-shaped steel bar operation difficulty problem is effectively solved, and the number of construction personnel and labor intensity are reduced.

The second driving member can drive the right horizontal support 211 to turn down to realize the opening of the upper platform 21, and when the upper platform 21 is opened, the steel bars thereon can automatically fall into the lower platform 22.

[0019] The lower platform 22 includes a guide rail 221 extending forward and backward. The guide rail 221 is mounted on the frame 1. A guide rail bracket 222 is slidably connected to the guide rail 221. Several transverse rollers 223 are spaced forward and backward on the guide rail bracket 222.

A third roller conveyor belt 35 is arranged side-by-side above the second roller conveyor belt 33, with the third roller conveyor belt 35 extending rearward, and a third linkage mechanism 36 is located below the third roller conveyor belt 35, and the third linkage mechanism 36 is equipped with a third power mechanism.

[0021] The first power mechanism drives the first linkage mechanism 32 to rotate, thereby flipping the reinforcing bars on the first roller conveyor belt 31 to the right onto the second roller conveyor belt 33. The second power mechanism drives the second linkage mechanism 34 to rotate, thereby flipping the reinforcing bars on the second roller conveyor belt 33 upward onto the third roller conveyor belt 35. Two or more reinforcing bars can be spliced ​​on the third roller conveyor belt 35 using sleeves. The third power mechanism drives the third linkage mechanism 36 to rotate, thereby flipping the spliced ​​reinforcing bars onto the storage conveyor mechanism 2.

The reinforcing bars come with connecting threads at the factory, and sleeve connections can be completed manually or by using mechanical equipment.

[0022] Ideally, the end face milling devices 37 of the reinforcing bars are evenly distributed in front of and behind the first roller conveyor belt 31.
