Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary equipment for automobiles in tunnels, and particularly relates to a hoisting and rotating turning device for automobiles in tunnel space. Background Technique
[0002] A water conveyance tunnel refers to a tunnel-type water conveyance structure, which is commonly used in water conservancy project construction projects. During project construction, automobiles are needed to transport bulk materials such as sand, soil, building materials, etc. In the limited space of the water conveyance tunnel, after the automobile completes the transportation task, it cannot turn around in the water conveyance tunnel.
[0003] The current method for an automobile to turn around is for the automobile to reverse all the way until the tunnel entrance, and then turn around in the broad space outside the tunnel. However, the turning method in the tunnel space has high requirements for the driver, and the driving difficulty is also great. It is easy to form the problems of small turning space and low turning efficiency, which not only affects the overall operation of water conservancy and hydropower engineering projects, but may also cause quality risks in certain situations. Content of the Utility Model
[0004] The technical problem solved by the utility model is to provide a hoisting and rotating turning device for automobiles in tunnel space, which turns around the automobile in the tunnel space, reduces the driving requirements, and thus improves the turning efficiency of the automobile in the limited space of the water conveyance tunnel.
[0005] To solve the above technical problem, the technical solution adopted by the utility model is as follows:
[0006] A hoisting and rotating turning device for automobiles in tunnel space includes a rotating platform and a driving motor. The output end of the driving motor faces downward and is connected to the rotating platform. The rotating platform is connected to the automobile through multiple first steel wires; it also includes a winch fixedly installed in the tunnel and a pulley assembly installed on the top of the tunnel; one end of a second steel wire is connected to the winch, and the other end of the second steel wire is connected to the pulley assembly and then to the driving motor; the driving motor is connected with a controller for controlling the rotation of the driving motor.
[0007] Further, the controller includes a signal emitter and a driver. The driver is installed on the driving motor and is electrically connected to the driving motor. The signal emitter is signal-connected to the driver.
[0008] Preferably, the pulley assembly includes a first pulley, a second pulley and a fixed seat. The first pulley and the fixed seat are installed on the top of the tunnel, and the second pulley is installed on the driving motor; the second steel wire bypasses the top of the first pulley and the bottom of the second pulley and then is connected to the fixed seat.
[0009] Preferably, the driving motor is a stepping motor.
[0010] Furthermore, a bottom plate is provided at the bottom of the winch, and the bottom plate is anchored in the tunnel by expansion bolts, and a heavy object is installed on the bottom plate.
[0011] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0012] After the first steel wire rope fixes the vehicle, the winch is used to lift the vehicle to a certain distance above the ground, and the driving motor is controlled to rotate a certain angle so that the vehicle completes a U-turn in a suspended state, avoiding the problem that a traditional vehicle needs to reverse the whole process until the tunnel entrance to complete a U-turn, reducing the driving difficulty and improving the U-turn efficiency. Description of the Drawings
[0013] Figure 1 It is a schematic diagram of the whole structure of the utility model.
[0014] Figure 2 It is a schematic diagram of the pulley assembly structure.
[0015] The meanings of the reference numerals in the figure are as follows: 1 - rotating platform, 2 - driving motor, 3 - tunnel, 4 - first steel wire rope, 5 - vehicle, 6 - winch, 7 - second steel wire rope, 8 - first pulley, 9 - second pulley, 10 - fixing seat. Specific Embodiments
[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model, so as to have a further understanding of the concept, the technical problems solved, the technical features constituting the technical solutions, and the technical effects brought by the present utility model.
[0017] As Figure 1 shown, a vehicle hoisting and rotating U-turn device in a tunnel space includes a rotating platform 1 and a driving motor 2. The output end of the driving motor 2 faces downward and is connected to the rotating platform 1. The rotating platform 1 is connected to the vehicle 5 through a plurality of first steel wire ropes 4; it also includes a winch 6 fixedly installed in the tunnel 3 and a pulley assembly installed at the top of the tunnel 3; one end of the second steel wire rope 7 is connected to the winch 6, and the other end of the second steel wire rope 7 is connected to the pulley assembly and then connected to the driving motor 2; the driving motor 2 is connected with a controller for controlling the rotation of the driving motor 2.
[0018] During the construction process of the tunnel 3, a vehicle 5 is needed to transport sand, soil or other building materials. After the vehicle 5 transports the materials into the tunnel 3 and unloads them, in the limited space of the water conveyance tunnel 3, the vehicle 5 cannot make a U-turn or turn after completing the transportation task. And the current solution is: the dump truck reverses the whole process until the tunnel 3 entrance, and makes a U-turn in the broad space outside the tunnel 3. The above-mentioned U-turn method in the tunnel 3 space has high requirements for the driver, great driving difficulty, and is prone to form conflicts in the operation space, resulting in low efficiency.
[0019] The improvement of the present utility model lies in that: the winch 6 is installed at the inner edge position of the tunnel 3 to avoid contact with the vehicle 5 itself. The second steel wire rope 7 of the winch 6 is connected to the pulley assembly and then to the drive motor 2, and the whole of the drive motor 2 and the rotating platform 1 can be lifted or lowered by controlling the winch 6. A plurality of first steel wire ropes 4 are connected to the rotating platform 1, and the first steel wire ropes 4 are pulled to each fixed point of the vehicle 5 to fix the vehicle 5 and ensure that the vehicle 5 does not deviate during the rotation process. During operation, the vehicle 5 is advanced to the installation position of the present utility model in the tunnel 3. After the first steel wire rope 4 fixes the vehicle 5, the winch 6 is used to lift the vehicle 5 to a certain distance above the ground, and the drive motor 2 is controlled to rotate a certain angle so that the vehicle 5 completes a U-turn in a suspended state, avoiding the problem that the traditional vehicle 5 needs to reverse the whole way until the tunnel 3 entrance to complete a U-turn, reducing the driving difficulty and improving the U-turn efficiency.
[0020] Furthermore, the controller includes a signal emitter and a driver. The driver is installed on the drive motor 2 and electrically connected to the drive motor 2, and the signal emitter is signal-connected to the driver. The traditional controller is connected to the drive motor 2 through a wire, resulting in a fixed installation position of the controller, and the staff also needs to use the controller near the controller. However, the lifting and rotating U-turn method of the vehicle 5 has a certain risk compared with the traditional U-turn method. Using the signal emitter to control the drive motor 2 by signals can allow the staff to select a better observation angle during the U-turn control process to ensure the smooth progress of the U-turn.
[0021] As Figure 2 shown, preferably, the pulley assembly includes a first pulley 8, a second pulley 9 and a fixed seat 10. The first pulley 8 and the fixed seat 10 are installed on the top of the tunnel 3, and the second pulley 9 is installed on the drive motor 2; the second steel wire rope 7 bypasses the top of the first pulley 8 and the bottom of the second pulley 9 and then is connected to the fixed seat 10. The above pulley hoisting method is double-pulley hoisting. The advantage of double-pulley hoisting is that the bearing capacity is stronger, and the safety is higher when hoisting heavy objects such as the vehicle 5.
[0022] Preferably, the drive motor 2 is a stepper motor. The rotation angle of the stepper motor is more accurate. The controller sends a signal pulse to the drive end of the stepper motor, and the drive end of the stepper motor converts the received signal pulse into an electrical pulse to drive the stepper motor to rotate. For each signal pulse sent by the controller, the stepper motor rotates an angle, and its rotation runs step by step at a fixed angle. By controlling the number of pulses, the rotation angle of the stepper motor can be controlled, so as to accurately control the rotation angle.
[0023] Further, a bottom plate is provided at the bottom of the winch 6. The bottom plate is anchored in the tunnel 3 by expansion bolts, and a heavy object is installed on the bottom plate. The gravity of the vehicle 5 is relatively large. Lifting and suspending the vehicle 5 forms a relatively large pulling force on the winch 6. The winch 6 is fixed by the expansion bolts and the heavy object, which increases the safety.
[0024] In the description of the present utility model, the terms "connection" and "fixation" may be fixed connection, machining forming, welding, or mechanical connection. The specific meanings of the above terms in the present utility model should be understood according to the specific circumstances.
