Description

Technical Field

[0001] The utility model relates to the technical field of tunnel shield construction equipment, in particular to the technical field of shield machine anti-collision beams. Background Art

[0002] A shield machine is a specialized piece of engineering machinery used for tunnel excavation. Modern shield machines integrate optical, mechanical, electrical, hydraulic, sensor, and information technologies, enabling them to excavate and cut soil, transport slag, and assemble tunnel linings. Electric vehicle transports of materials, such as soil and pipe segments, can slip due to equipment failure. If the tunnel is sloping, the vehicle can slide uncontrollably, generating significant inertia due to its weight acceleration. If it were to crash into the shield machine, it could cause serious damage to personnel and equipment.

[0003] Currently, most shield tunneling systems are equipped with anti-collision beams only on the No. 1 trolley. If a battery-powered vehicle transporting materials accidentally enters the trolley containing the rear section of the rear section, it can endanger personnel within the rear section, causing casualties and property damage. This means that the anti-collision beams on the No. 1 trolley are not providing timely protection. Utility Model Content

[0004] To address the above-mentioned issues, the present utility model discloses an automatically triggered shield machine anti-collision beam. This relates to the technical field of tunnel shield construction equipment. This method effectively addresses the significant safety hazard posed to shield construction workers by actively and passively triggering the shield machine's anti-collision beam.

[0005] The automatically triggered shield machine anti-collision beam is characterized by:

[0006] It includes an anti-collision beam assembly and a trigger assembly; the trigger assembly controls the anti-collision beam assembly to automatically lower the beam;

[0007] The anti-collision beam assembly includes: a motor, a reducer, a bearing base, a bearing, a drum rod, a wire rope, an anti-collision beam, a buffer base and a buffer; the trigger assembly includes: a control box, an audible and visual alarm and a speedometer;

[0008] The motor is connected to the reducer; the load end of the reducer is connected to the load end of the drum rod; the bearing is used to support and fix the drum rod so that it can rotate in mid-air; one end of the wire rope is wound around the drum of the drum rod; the other end of the wire rope is connected to the anti-collision beam; the anti-collision beam is arranged on the side of the structural columns on both sides of the trolley including the rear supporting tail part opposite to the excavation direction of the shield machine, and a buffer base is welded on the anti-collision beam; a buffer is installed on the buffer base.

[0009] Furthermore, the control box is arranged on one side of the trolley of the rear supporting tail part of the shield machine, the sound and light alarm is installed on the top cross beam of the trolley of the rear supporting tail part of the shield machine, and the speed meter is installed on the tunnel segment; the anti-collision beam assembly is controlled to rise and fall by the control box; the sound and light alarm is used to broadcast the sound of "the battery car is slipping, and people should evacuate the shield machine quickly", and the control box has a built-in time relay, and the time relay is set to cut off the power in 10 seconds.

[0010] The beneficial effects of the utility model are:

[0011] 1. This new anti-collision beam is installed on the top crossbeam of the trolley that contains the rear part of the rear set. When triggered, the anti-collision beam lands on the rear part of the trolley that contains the rear set, so that the impact occurs at the outermost part of the rear set, ensuring the safety of people in the rear set to the greatest extent.

[0012] 2. The anti-collision beam assembly of the utility model is arranged on the side of the structural columns on both sides of the trolley including the rear supporting tail part, which is opposite to the excavation direction of the shield machine. The resistance of the structural columns is better than that of other positions, which can reduce the bearing pressure of the shield machine.

[0018] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0019] Example 1

[0020] This embodiment provides an automatically triggered shield machine anti-collision beam, which is characterized by comprising an anti-collision beam component and a trigger component; the trigger component controls the anti-collision beam component to automatically lower the beam. Figure 1 The anti-collision beam assembly includes: a motor 1, a reducer 2, a bearing base 3, a bearing 4, a drum rod 5, a wire rope 6, an anti-collision beam 7, a buffer base 8 and a buffer 9; Figure 2 and Figure 3 As shown, the trigger component includes: a control box 10, an audible and visual alarm 11 and a speed meter 12.

[0021] The automatically triggered shield machine anti-collision beam adopts an electronically controlled descending type. When the speed meter 12 detects that an object in the tunnel moves at a speed exceeding 20 km / h (the trigger threshold of the speed meter can be set by yourself), the normally open contact of the speed meter 12 is closed and energized to transmit a signal to the control box 10. The speed meter 12 is installed on the tunnel segment. The control box 10 is arranged on one side of the trolley of the rear supporting tail part of the shield machine. The control box 10 has a built-in time relay, and the time relay is set to power off in 10 seconds to prevent the wire rope from being released too much. After receiving the transmission signal, the control box 10 controls the anti-collision component to automatically start, and the relay starts countdown. At the same time, the sound and light alarm 11 starts to broadcast the sound of "the battery car is slipping, and personnel quickly evacuate the shield machine". The sound and light alarm 11 is installed in a conspicuous position on the top crossbeam of the trolley of the rear supporting tail part of the shield machine. After the anti-collision component is automatically started, the relevant personnel will contact the battery car driver transporting materials through the intercom to confirm whether the car is slipping to prevent losses caused by the erroneous triggering of the speed meter 12.

[0022] After the motor 1 is energized, it rotates through the gear transmission reducer 2. The load end of the reducer 2 is connected to the load end of the drum rod 5. The reducer 2 drives the drum rod 5 to rotate. The bearing 4 is used to support and fix the drum rod 5 so that it rotates in mid-air. The bearing base 3 is used to fix the bearing 4. As the drum rod 5 rotates, the wire rope 6 hangs the anti-collision beam and descends. It is lowered into place within 10 seconds. One end of the wire rope 6 is wound around the drum of the drum rod 5; the other end of the wire rope 6 is connected to the anti-collision beam 7; the anti-collision beam 7 is arranged on the side of the structural columns on both sides of the trolley including the rear matching tail part opposite to the excavation direction of the shield machine. The buffer base 8 is welded on the anti-collision beam 7; the buffer base 8 is installed on the buffer 9.

[0023] Example 2

[0024] This embodiment provides an automatically triggered anti-collision beam of a shield machine, which is characterized in that the method of triggering the anti-collision beam assembly in this embodiment is: manually pressing the descending button of the control box 10, and the anti-collision beam assembly is passively started; the rest is the same as the implementation method of Example 1.
