Description

Technical Field

[0001] This utility model relates to the field of concrete segment assembly technology, specifically a leveling device for concrete segment assembly. Background Technology

[0002] Concrete segments are precast concrete structural components mainly used in the construction of tunnels, underground engineering and pipelines. They are often used as support structures for shield tunnels to ensure the stability and safety of the tunnel.

[0003] Concrete tunnel segments are mainly made of raw materials such as cement, sand, and gravel through mixing and pouring. The segments can provide temporary support during tunnel excavation to prevent tunnel collapse and can withstand the load of the tunnel. Depending on different engineering requirements, the shape, size and strength of the segments can vary. Common shapes include circular and elliptical. Concrete tunnel segments have good durability and compressive strength and can maintain stability during long-term use.

[0004] During the segment assembly process, the transport device delivers the segments to the lower end of the clamping device. The clamping head at one end of the clamping device moves into the corresponding segment groove to clamp the segment. Then, the segment is moved to the installation area for assembly. However, during the transport process, the segments may shift, causing the segment groove to move. This results in the clamping head not aligning with the segment groove after the transport device delivers the segment to the lower end of the clamping device. Construction workers need to lift the segment to level it, but the segment is heavy, making adjustment inconvenient. This increases the workload of the workers and reduces the efficiency of the segment assembly operation. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a leveling device for assembling concrete pipe segments to solve the technical problems mentioned above in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leveling device for assembling concrete pipe segments, comprising a device body, with mounting brackets symmetrically mounted on the upper end of the device body, and limiting shafts movably mounted inside both sets of mounting brackets. A reserved groove is provided on the upper end of the device body, and limiting shafts are movably mounted inside the reserved groove. Protective sleeves are installed on the outer walls of multiple sets of limiting shafts. A drive motor is installed inside the device body, and a drive shaft is installed at the output end of the drive motor, and the drive shaft is movably connected to multiple sets of limiting shafts.

[0007] By adopting the above technical solution, the problem of adjusting the horizontal position of the tunnel segments is solved. If the tunnel segments shift after transportation, the drive shaft rotates, which in turn drives multiple sets of limit shafts to rotate, thereby driving multiple sets of protective sleeves to rotate. The outer walls of the multiple sets of protective sleeves connect with the outer walls of the tunnel segments, causing the tunnel segments to shift and thus adjusting the horizontal position of the tunnel segments. This reduces the workload of the workers and improves the efficiency of tunnel segment assembly operations.

[0008] The present invention is further configured such that the drive shaft is connected to the two sets of limiting shafts by a synchronous belt, and a movable shaft is movably installed inside the main body of the device, and the movable shaft is connected to the two limiting shafts by a synchronous belt.

[0009] Preferably, the drive shaft rotates, and the drive shaft is connected to two sets of limit shafts via synchronous belts. The two sets of limit shafts rotate, and one set of limit shafts is connected to the movable shaft via a synchronous belt. The movable shaft rotates, and the movable shaft is connected to the remaining set of limit shafts via a synchronous belt. Therefore, the remaining set of limit shafts rotates.

[0010] The present invention is further configured such that support plates are symmetrically installed on the upper end of the main body of the device, and one end of each set of support plates is arc-shaped.

[0011] Preferably, one end of each of the two sets of support plates provides auxiliary support to both ends of the tunnel segment.

[0012] The present invention is further configured such that baffles are symmetrically installed on the outer walls of the two sets of support plates, and the outer walls of multiple sets of baffles are covered with rubber pads.

[0013] Preferably, when the main body of the device moves the tunnel segment, multiple sets of baffles protect the tunnel segment and prevent it from slipping.

[0014] The present invention is further configured such that a reserved groove is provided at one end of each of the two sets of baffles, and a detection probe is installed on the inner wall of each of the two sets of reserved grooves.

[0015] Preferably, two sets of detection probes detect both ends of the tube segment respectively. If the horizontal position of the tube segment shifts, one set of detection probes loses illumination on one end of the tube segment.

[0016] The present invention is further configured such that the two sets of detection probes are at the same horizontal height, and both sets of detection probes are electrically connected to the drive motor.

[0017] Preferably, if the horizontal displacement of the tunnel segment causes a shift, the detection probe detects the shift and starts the drive motor.

[0018] The present invention is further configured such that all of the protective sleeves are made of rubber.

[0019] Preferably, the friction between multiple sets of protective sleeves and the outer wall of the tunnel segment is increased, thereby enhancing the effect of the protective sleeves in moving the tunnel segment.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention solves the problem of adjusting the horizontal position of tunnel segments by incorporating a detection probe, a limiting shaft, and a protective sleeve. If a tunnel segment shifts after transportation, the drive shaft rotates, causing multiple sets of limiting shafts to rotate, which in turn causes multiple sets of protective sleeves to rotate. The outer walls of the multiple sets of protective sleeves connect with the outer walls of the tunnel segments, causing the tunnel segments to shift and thus adjusting their horizontal position. This reduces the workload of workers and improves the efficiency of tunnel segment assembly. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A leveling device for assembling concrete tunnel segments, such as Figure 1 - Figure 4As shown, the device includes a main body 1, with symmetrical mounting brackets 10 on the upper end of the main body 1. Limiting shafts 7 are movably installed inside both sets of mounting brackets 10. A pre-reserved groove 2 is provided on the upper end of the main body 1, with the limiting shafts 7 movably installed inside the groove 2. Protective sleeves 8 are installed on the outer walls of the multiple sets of limiting shafts 7. A drive motor 5 is installed inside the main body 1, and a drive shaft 6 is installed at the output end of the drive motor 5. The drive shaft 6 is movably connected to the multiple sets of limiting shafts 7. When the drive shaft 6 rotates, it drives the multiple sets of limiting shafts 7 to rotate synchronously, thereby driving the multiple sets of protective sleeves 8 to rotate, and thus causing the pipe segments to shift, leveling the horizontal position of the pipe segments. This facilitates the clamping device in clamping and handling the pipe segments, reducing the workload of workers and improving the efficiency of pipe segment assembly operations.

[0031] Please see Figure 4 The drive shaft 6 is connected to two sets of limit shafts 7 by a synchronous belt. The main body 1 of the device has a movable shaft 9 installed inside, and the movable shaft 9 is connected to two sets of limit shafts 7 by a synchronous belt. When the drive shaft 6 rotates, the drive shaft 6 is connected to the two sets of limit shafts 7 by a synchronous belt, and the two sets of limit shafts 7 rotate. One set of limit shafts 7 is connected to the movable shaft 9 by a synchronous belt, and the movable shaft 9 rotates. The movable shaft 9 is connected to the remaining set of limit shafts 7 by a synchronous belt, so the remaining set of limit shafts 7 rotates.

[0032] Please see Figure 1 - Figure 2 The main body 1 of the device is symmetrically equipped with support plates 12, and one end of each set of support plates 12 is arc-shaped, and one end of each set of support plates 12 provides auxiliary support for both ends of the tube segment.

[0033] Please see Figure 1 - Figure 2 Two sets of support plates 12 are symmetrically equipped with baffles 11 on their outer walls, and the outer walls of multiple sets of baffles 11 are covered with rubber pads. When the main body 1 of the device moves the pipe segment, multiple sets of baffles 11 protect the pipe segment and prevent it from slipping.

[0034] Please see Figure 1 - Figure 3 Both sets of baffles 11 have a reserved groove 3 at one end. Both sets of reserved grooves 3 are equipped with detection probes 4 on their inner walls. The two sets of detection probes 4 detect both ends of the tube segment. If the horizontal position of the tube segment shifts, one set of detection probes 4 loses its illumination of one end of the tube segment.

[0035] Please see Figure 1 - Figure 4 The two sets of detection probes 4 are at the same horizontal height, and both sets of detection probes 4 are electrically connected to the drive motor 5. If the horizontal displacement of the tube segment causes a shift, the detection probe 4 will detect the shift of the tube segment, and the drive motor 5 will start.

[0036] Please see Figure 2 - Figure 4 All the protective sleeves 8 are made of rubber, which increases the friction between the protective sleeves 8 and the outer wall of the pipe segment, and improves the effect of the protective sleeves 8 in moving the pipe segment.

[0037] The working principle of this utility model is as follows: The operator installs the main body 1 of the device on the upper end of the transport device, and then places the pipe segment on the upper end of the main body 1. The transport device moves the main body 1 and the pipe segment to the lower end of the clamping device. Two sets of detection probes 4 detect both ends of the pipe segment respectively. If the pipe segment deviates, the drive motor 5 starts and drives the drive shaft 6 to rotate. The drive shaft 6 is connected to two sets of limit shafts 7 through a synchronous belt. The two sets of limit shafts 7 rotate. One set of limit shafts 7 is connected to the movable shaft 9 through a synchronous belt. The movable shaft 9 rotates. The movable shaft 9 is connected to the remaining set of limit shafts 7 through a synchronous belt. Therefore, the remaining set of limit shafts 7 rotates. The multiple sets of limit shafts 7 rotate synchronously, thereby driving the multiple sets of protective sleeves 8 to rotate. The multiple sets of protective sleeves 8 are all movably connected to the outer wall of the pipe segment, thereby driving the pipe segment to move and level the horizontal position of the pipe segment. This makes it easier for the clamping device to clamp and pick up the pipe segment, reducing the workload of the operator and improving the efficiency of the pipe segment assembly operation.
