Description
Technical Field
[0001] The present application relates to the technical field of tunnel construction equipment, and in particular to an automatic slag dumping system for a tunnel. Background Art
[0002] Suspension bridges, as long-span bridges, require specialized anchoring structures to ensure construction safety. Tunnel anchorages, on the other hand, require tunneling through bedrock, using concrete or anchor plates at the bottom to provide cable tension and meet the demands of bridge construction.
[0003] In the actual construction of tunnel anchors, slag is mainly discharged through rail-mounted slag trucks. The slag is loaded into the slag trucks by excavators. The slag trucks are towed by winders arranged outside the tunnel anchors and travel on the tracks to the outside of the tunnel anchors for slag discharge. The slag discharge process requires the slag trucks to be lifted and turned over, so that the slag is poured into the dump trucks to complete the slag discharge.
[0004] Regarding the above-mentioned related technologies, when the slag truck is lifted and flipped over to discharge slag, if the flipping angle is small, some slag will still remain in the slag truck; if the flipping angle is large, a large amount of slag will fall onto the slag truck at the same time, and the slag truck will be subjected to greater pressure and easily damaged, so there is room for improvement. Utility Model Content
[0005] In order to improve the efficiency of tunnel slag discharge, the present application provides a tunnel automatic slag dumping system.
[0006] The present application provides a tunnel automatic slag dumping system that adopts the following technical solutions:
[0007] A tunnel automatic slag dumping system comprises a track, which is laid on the tunnel, and a dumping platform is provided at one end of the track located at the tunnel exit; the system also comprises a base, a slag discharge vehicle, a traction assembly, a sealing plate, a drive assembly, a lifting piece and a buffer mechanism, wherein the base is slidably installed on the tunnel, and the slag discharge vehicle is installed on the side of the base away from the tunnel; the traction assembly is used to drive the base to move along the track; the sealing plate is slidably connected to one end of the slag discharge vehicle, and the drive assembly is used to drive the sealing plate to slide in the height direction of the slag discharge vehicle; the lifting piece is used to lift the end of the slag discharge vehicle away from the sealing plate; and the buffer mechanism is used to buffer the slag dumped from the slag discharge vehicle.
[0008] By adopting the above technical solution, the setting of the drive component can control the lifting and lowering of the sealing plate. When the lifting part drives the slag discharger to tilt, it drives the sealing plate to slide, which helps to control the slag discharge speed of the slag, thereby reducing the damage to the slag discharger caused by a large amount of slag falling at the same time; the buffer mechanism is set to buffer the dumped slag, further reducing the pressure of the slag on the slag discharger.
[0009] Preferably, the traction assembly includes a winch and a steering wheel; the winch is installed on the tipping platform, a steel wire rope is provided on the winch, and one end of the steel wire rope is connected to the base; the steering wheel is installed on the track.
[0010] By adopting the above technical solution, when the slag truck is located on the inclined section of the track, the wire rope abuts against the steering wheel, and the setting of the steering wheel guides the wire rope.
[0011] Preferably, a position identification module is further included, and the lifting member and the winch are both controlled by the position identification module. When the position identification module detects that the slag truck moves to the tilting platform, the winch stops working and the lifting member works to lift the end of the slag truck away from the sealing plate.
[0012] By adopting the above technical solution, the setting of the position identification module helps to improve the degree of automation of this system. When the position identification module detects that the slag truck moves to the tilting platform, the winch stops winding the wire rope, and the lifting part lifts one end of the slag truck for subsequent slag discharge; reducing manual operations, thereby helping to improve the slag discharge efficiency of this system.
[0013] Preferably, a tilting plate is provided in the slag discharge car, and one end of the tilting plate away from the sealing plate is tilted downward.
[0014] By adopting the above technical solution, the setting of the tilting plate allows the slag car to slide out of the slag car along the tilting plate without turning over a large angle. The setting of the tilting plate helps to improve the slag discharge efficiency.
[0015] As an advantage, sliding blocks are provided on both sides of the sealing plate, and sliding grooves for the sliding blocks to slide are provided on the slag discharge vehicle.
[0016] By adopting the above technical solution, the sliding block slides along the sliding groove, which helps to improve the stability of the sealing plate when it slides along the height direction of the slag discharge vehicle, thereby helping to improve the slag discharge efficiency.
[0017] Preferably, the driving assembly includes a driving cylinder and a connecting plate, the driving cylinder is installed on the side wall of the slag discharger, the connecting plate is fixedly connected to the sealing plate, and the connecting plate is fixedly connected to the output end of the driving cylinder; the driving cylinder drives the sealing plate to move along the height direction of the slag discharger through the connecting plate.
[0018] By adopting the above technical solution, under the drive of the driving cylinder, the sealing plate slides along the height direction of the slag car, so that the slag in the slag car slides out of the slag car from the bottom end of the sealing plate. The structure is simple, the slag is automatically discharged, and the efficiency is high.
[0019] Preferably, the buffer mechanism includes a support frame and two sets of guide plates arranged opposite to each other, the two guide plates are correspondingly mounted on the support frame, and the two guide plates have different heights.
[0020] By adopting the above technical solution, two sets of guide plates are staggered, and the slag falls onto the guide plates and then slides along the guide plates onto the slag truck. The guide plates guide the sliding of the slag and at the same time reduce the slag falling directly onto the slag truck and the greater pressure on the slag truck, which has a certain protective effect on the slag truck. The setting of the guide plates has practical benefits.
[0021] Preferably, the buffer mechanism also includes multiple groups of buffer springs, the guide plates are all slidably connected to the support frame, and multiple groups of sliding rods are provided on the side of the guide plate close to the support frame, and the support frame is provided with a sliding groove for the sliding rods to slide; the buffer springs correspond one-to-one to the sliding rods, and the buffer springs are sleeved on the sliding rods, one end of the buffer spring abuts against the guide plate, and the other end of the buffer spring abuts against the support frame.
[0022] By adopting the above technical solution, the setting of the buffer spring further buffers the slag falling onto the guide plate, absorbs part of the impact force when the slag falls, and has a certain protective effect on the guide plate; the sliding rod slides along the slide groove, thereby improving the stability of the guide plate during the sliding process, which in turn helps to improve the stability of the buffer mechanism structure.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The drive assembly is designed to control the lifting and lowering of the sealing plate. When the lifting component drives the slag truck to tilt, it drives the sealing plate to slide, which helps control the slag discharge speed and thus reduces the damage to the slag truck caused by a large amount of slag falling at the same time. The buffer mechanism is set to cushion the dumped slag, further reducing the pressure of the slag on the slag truck.
[0025] 2. The setting of the position recognition module helps to improve the automation level of this system. When the position recognition module detects that the slag truck has moved to the tilting platform, the hoist stops reeling in the wire rope, and the lifting part lifts one end of the slag truck for subsequent slag discharge. This reduces manual operation and helps to improve the slag discharge efficiency of this system.
[0026] 3. The tilting plate is set so that the slag car does not need to turn over a large angle, and the slag can slide out of the slag car along the tilting plate, thereby improving the slag discharge efficiency;
[0027] 4. The setting of the guide plate guides the sliding of the slag, and at the same time reduces the slag falling directly onto the slag truck and the greater pressure on the slag truck, which has a certain protective effect on the slag truck and has practical benefits.
