Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and in particular to a tunnel anchor track type intelligent slag discharge system and method. Background Art

[0002] At present, the vast majority of ground-anchored suspension bridges use gravity anchors or tunnel anchors to anchor the main cables. Tunnel anchors are a type of anchor structure that can better utilize the geological conditions of the anchoring area, has a relatively small engineering volume (only 20% to 25% of that of a gravity anchor), is cost-effective, and has little disturbance to the surrounding environment. They are mostly used for suspension bridges with larger spans in mountainous areas.

[0003] There are two main methods of slag removal in existing tunnel anchor construction: one is to use a conveyor belt to remove slag, which is only suitable for tunnel anchors with a small inclination angle and a small volume. When the inclination angle of the tunnel anchor is large, there is a high risk of slag falling back during the conveying process; the second is to use a rail-type slag removal vehicle for slag removal. The slag is loaded into the slag removal vehicle using an excavator. The slag removal vehicle is towed by a winder arranged on the outside of the tunnel anchor, travels on the track to the outside of the tunnel anchor, and pours the slag into a dump truck to complete the slag removal. Although this method is suitable for tunnel anchor construction with extremely long inclination angles, the slag removal vehicle is prone to slipping and sliding in the anchor hole with a large slope, posing a great safety hazard to the construction personnel and equipment in the tunnel anchor.

[0004] As the span of suspension bridges increases, the length and inclination of tunnel anchors continue to increase, and the amount of excavation also increases. In the construction of long and steep tunnel anchors, rail-mounted slag trucks are more common. Currently, this method has the following disadvantages:

[0005] 1. Significant safety hazards: The operation of the slag car is entirely dependent on the winch's rope reeling and releasing. When the winch fails or the traction wire rope breaks due to excessive wear, it will cause problems such as slipping and sliding. During the operation of the slag car, if there are other obstacles such as fallen rocks on the track, there is a risk of derailment.

[0006] 2. Low level of intelligence: Currently, the braking of the slag truck in its downward movement and other situations mainly relies on manual communication through walkie-talkies, which has high delay and low fault tolerance. When the winch traction wire rope is severely worn or there are obstacles such as fallen rocks in front of the track, the system cannot brake automatically. Due to the differences in the looseness and porosity of the slag material, the slag truck transports different volumes of slag each time. The slag discharge efficiency calculated by manually counting the number of slag discharges by the slag truck is poorly calculated.

[0007] 3. Low slag discharge efficiency: Tunnel anchor excavation requires a huge amount of volume, and the speed of track-type slag discharge is affected by the stability and safety of the system. If machine failures or safety issues occur frequently, the slag discharge efficiency will be greatly reduced, causing the construction progress to lag behind. Summary of the Invention

[0035] Note: The following example is only a specific example and is not intended to limit the embodiments of the present invention to the following specific steps, values, conditions, data, sequence, etc. Those skilled in the art can apply the concepts of the present invention to construct more embodiments not described in this specification by reading this specification.

[0036] There are two main methods of slag removal in existing tunnel anchor construction. One is to use a conveyor belt to remove slag, and the other is to use a track 8 slag vehicle 4 to remove slag. As the span of the suspension bridge increases, the length and inclination of the tunnel anchor continue to increase, and the excavation volume also increases accordingly. The existing track-type slag vehicle 4 slag removal method has the following disadvantages: great safety hazards, low degree of intelligence, and low slag removal efficiency.

[0037] In view of this, an embodiment of the present invention provides a tunnel anchor track type intelligent slag discharge system, which is used to solve the technical problems of existing track type slag discharge systems, such as large safety hazards, low intelligence level and low slag discharge efficiency.

[0038] First, please refer to Figure 1 The present application provides a tunnel anchor track type intelligent slag discharge system, including a track mechanism, a traction mechanism and a control mechanism, wherein the track mechanism includes a track 8, which is laid between the slag discharge tunnel anchor face and the slag truck 13; the traction mechanism includes a hoist 14, a first steering wheel 12, a second steering wheel 6, a bracket 10, a traction wire rope 9 and a slag discharge truck 4, wherein the bracket 10 and the hoist 14 are both arranged on the slag discharge platform, the first steering wheel 12 is rotatably arranged on the top of the bracket 10, and the second steering wheel 6 is rotatably arranged on the track 8, the traction wire rope 9 is pulled by the hoist 14 and the slag discharge truck 4 is pulled by the first steering wheel 12 and the second steering wheel 6. Move along the track 8; the control mechanism includes an encoder 7, a tension sensor 5 and a control module, the encoder 7 is arranged on the output shaft of the winch 14 reducer, and is used to detect the speed and traction time of the winch 14 for retracting or releasing the rope, and the tension sensor 5 is arranged at the connection of the traction wire rope 9 and the slag car 4, and is used to obtain the tension to which the slag car 4 and the slag material loaded thereon are subjected during operation, the control module is used to obtain the speed and traction time of the winch 14 for retracting or releasing the rope detected by the encoder 7 to obtain the position of the slag car 4 on the track 8, and is also used to obtain the slag discharge efficiency of the slag discharge system according to the obtained tension to which the slag car 4 and the slag material loaded thereon are subjected during operation.

[0039] The tunnel anchor track-type intelligent slag discharge system provided by the present application uses a winch 14 in combination with a first steering wheel 12 and a second steering wheel 6 to pull a slag discharge vehicle 4. This system is suitable for tunnel anchor construction with a large inclination angle. In addition, the slag discharge vehicle 4 is less likely to slip or slide in an anchor hole with a large slope, thereby improving the construction safety of the slag discharge system.

[0040] The control mechanism including the encoder 7, the tension sensor 5 and the control module obtains the tension exerted on the slag discharge vehicle 4 and the slag material loaded thereon during operation, as well as the speed and traction time of the winch 14 for retracting and releasing the rope, thereby obtaining the slag discharge efficiency of the slag discharge system and the slag discharge status of the slag discharge vehicle 4, providing an intelligent slag discharge system.

[0041] When the excavation volume of the tunnel anchor is large, the control module is used to control the retraction and release rope of the winch 14, thereby reducing the machine failure rate and safety issues of the slag discharge system, effectively ensuring the operational stability of the slag discharge system, and reducing the probability of situations where the slag discharge efficiency is affected by machine failures and safety accidents.

[0042] In one embodiment, the encoder 7 is arranged on the output shaft of the reducer of the hoist 14 and can detect the rope-reeling or rope-releasing speed of the hoist 14, which can be equivalently understood as the running speed of the slag car 4.

[0047] In one embodiment, the control module is also used to send an alarm message to notify the management personnel when the running speed of the slag truck 4 exceeds the normal range (preset speed range) and control the winch 14 to actively brake, so as to avoid safety accidents or machine accidents caused by the overspeed of the slag truck 4, or to realize early maintenance of equipment failure under the condition of low running speed of the slag truck 4, so as to avoid the occurrence of major machine failures affecting the progress of the slag construction project.

[0048] The present application uses the first steering wheel 12 and the second steering wheel 6 to play a traction and guiding role on the traction wire rope 9 between the winch 14 and the slag car 4, effectively ensuring the stable driving of the slag car 4, avoiding the interference of the slag falling from the slag car 4 or the occurrence of pulleys and slips during slag discharge from the anchor hole with a larger slope, and through the intelligent lifting design of the second steering wheel 6, the traction and guidance is achieved without affecting the technical effect of the smooth driving of the slag car 4 along the track 8 with a larger inclination angle and longer length.

[0049] In the transformed embodiment of the present application, the number of the second steering wheels 6 can also be designed to be multiple according to the depth of the tunnel anchor or the length of the track 8, and can be arranged at intervals along the preset driving route of the slag truck 4 on the track 8, and can be raised and lowered in sequence through a lifting design. When the slag truck 4 approaches the second steering wheel 6, space is left to avoid interfering with the slag truck 4 continuing to travel along the track 8 toward the first steering wheel 12.
