Description

Technical Field

[0001] This utility model belongs to the technical field of turning devices, and in particular relates to an electric turning device for tube sections. Background Technology

[0002] Rectangular pipe jacking tunnels are a novel pipe jacking technology developed and applied abroad in the 1990s. Due to its advantages such as high cross-sectional utilization, shallow overburden, and low construction cost, this technology can be used for urban pedestrian tunnels, vehicular tunnels, underground utility tunnels, water diversion and drainage pipeline projects. In recent years, pipe jacking tunnels of different shapes and volumes have emerged to meet the needs of urban development. The turning over of prefabricated pipe sections is a relatively dangerous part of the construction process. Currently, most pipe section turning supports on the market still rely on installing the pipe sections on steel turning frames and then turning them over using a crane.

[0003] However, this method of turning over has the following problems:

[0004] 1) Pipe section turning is a high-risk operation, which must be directed by a dedicated safety officer and all unauthorized personnel must be evacuated from the work area. During the operation, a crane is used for transportation, and the pipe section turning frame must be compatible with the dimensions of the pipe section to be turned. The height of the crane should be greater than the diagonal of the pipe section. When turning the pipe section, professional workers need to install the turning ropes, and then a special crane is used to pull the ropes for turning. The pipe section turning operation is time-consuming and has high safety risks.

[0005] 2) Existing electric pipe section turning and lifting devices use steel structures and are heavy. The pipe sections need to be fixed to the turning and lifting device, and then a heavy-duty overhead crane is used to lift the device and the pipe sections into the air for turning. This places high demands on the crane's lifting capacity. Furthermore, due to the structure of the pipe section turning and lifting device, the maximum weight of the pipe sections is also limited, generally not exceeding 80t. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that when turning pipe sections, it is necessary to arrange professional operators to install turning ropes for the pipe sections and then equip them with special cranes to pull ropes for turning; the operation time is long and the safety risks are high. When using electric pipe section turning lifting tools to turn pipe sections, the maximum weight of the pipe section is limited to 80t. Therefore, an electric pipe section turning device is proposed.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an electric turning device for pipe sections.

[0008] include:

[0009] A turning frame is provided with limit frames on both sides, and a telescopic rotary motor and a positioning pin are respectively connected to the limit frames on both sides of the turning frame;

[0010] The device includes several electrically operated telescopic limit buckles connected to the turning frame. The pipe section is placed on the turning frame, and the telescopic rotary motor and the positioning pin abut against the pipe section. A control box is provided on the side end of the turning frame.

[0011] As a further description of the above technical solution:

[0012] The limiting frame is provided with a limiting groove. The telescopic rotary motor is installed on the limiting frame on one side of the turning frame. The motor shaft passes through the limiting groove and is positioned on the pipe section. The positioning pin passes through the limiting groove on the other side of the limiting frame and is positioned on the pipe section.

[0013] As a further description of the above technical solution:

[0014] The pipe section is provided with positioning holes.

[0015] As a further description of the above technical solution:

[0016] Several of the aforementioned electric telescopic limit buckles are arranged in two layers on the turning frame.

[0017] As a further description of the above technical solution:

[0018] The electric telescopic limit buckle includes a miniature telescopic motor and a limit shaft. The miniature telescopic motor is connected to the turning frame, and the limit shaft is connected to the miniature telescopic motor.

[0019] As a further description of the above technical solution:

[0020] The turning frame is equipped with reinforcing frames on both sides. The reinforcing frames are trapezoidal in shape, wider at the bottom and narrower at the top. The limiting frame is connected to the reinforcing frames.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, the pipe section is placed on the tilting frame, and a telescopic rotary motor extends out and is positioned in a positioning hole on one side of the pipe section, while a positioning pin is positioned in a positioning hole on the other side of the pipe section. When tilting is required, the control box controls the telescopic rotary motor to rotate, thereby achieving automatic tilting of the pipe section. This tilting frame structure has simple force distribution, and the reliance on the maximum lifting weight of the overhead crane can be reduced when tilting the pipe section. Under the same overhead crane lifting weight, compared with an electric tilting device for pipe sections, it can tilt pipe sections with a greater self-weight.

[0023] 2. In this utility model, by improving the original manual turning process, a pipe section turning motor is added, and the pipe section is turned by remote control, eliminating the need for manual threading of steel wire ropes and traction by crane, thus improving construction efficiency and personnel safety.

[0024] 3. In this utility model, the electric pipe section turning frame can improve the pipe section turning efficiency and reduce the number of pipe section operators. During the pipe section turning process, one overhead crane is eliminated for auxiliary operation. Moreover, compared with electric turning hoists, it can make the most efficient use of the maximum lifting capacity of the overhead crane, avoiding the reduction of the pipe section's weight due to the weight of the electric pipe section turning frame, which is more advantageous for turning heavy pipe sections.

[0025] 4. In this utility model, conventional pipe section turning frames lack protective devices during the pipe section turning process, which may lead to the pipe section flipping in the opposite direction and causing personnel injury. To address this issue, the electric pipe section turning frame is designed with an electric telescopic limit buckle to prevent the pipe section from flipping in the opposite direction during the turning process. After the pipe section is turned, the electric telescopic limit buckle can stabilize the pipe section, providing a safe operating space for the operator.

[0026] 5. In this utility model, the electric telescopic limiting buckle is set in two layers to accommodate the flipping of pipe sections of different thicknesses, so that the movement of the pipe section is limited during the flipping process to prevent the pipe section from flipping in the opposite direction.
