[0002] During the construction of railway tunnels, when constructing the secondary lining concrete, the contact network groove needs to be embedded in the secondary lining. In order to ensure the positioning progress of the groove, rectangular holes need to be opened on the template trolley panel, and T-bolts are used to position the embedded groove through the reserved holes.

[0003] The following problems exist in the current construction: After the secondary lining is completed, the T-bolts need to be removed before demoulding. Due to the large number of T-bolts, there are cases where T-bolts are missed during construction. If the T-bolts are not completely removed, the groove will be damaged during demoulding by the trolley. The damaged groove is extremely difficult to repair, which may cause some concrete to be scrapped and re-constructed. To this end, we propose a T-bolt intelligent detection system.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution: a T-bolt intelligent detection system, comprising a trolley panel 1, a plurality of grooves 2 and bolts 3, the grooves 2 being pre-buried in concrete, the trolley panel 1 being arranged on the upper surface of the opening side of the grooves 2, and the trolley panel 1 being provided with a rectangular through groove matching the top end of the bolt 3, the top end of the bolt 3 passing through the through groove and entering the groove 2 and then being rotated 90° and installed in the groove 2, the threaded portion of the bolt 3 being threadedly connected with a detection nut 4, the detection nut 4 being provided with a screw hole 12 matching the bolt 3, and the detection nut 4 being arranged on the upper surface of the trolley panel 1, and being tightened on the bolt 3 to fix the position of the bolt 3.

[0021] A built-in battery and a wireless sensor are respectively provided in the detection nut 4. The built-in battery is preferably a commonly used rechargeable lithium-ion battery. A switch 5 electrically connected to the built-in battery and the wireless sensor is respectively provided on the side surface of the detection nut 4 close to the trolley panel 1. The switch 5 is a button switch. When pressed, the wireless sensor is turned on. When released, it will automatically pop up to disconnect the electrical connection between the wireless sensor and the built-in battery.

[0022] The intelligent detection system is composed of at least 30 detection nuts 4 and an intelligent control cabinet. The bolt 3 is fixed on the trolley panel 1 by an intelligent detection nut 4. After the detection nut 4 is tightened, its switch 5 is pressed on the trolley panel 1, thereby triggering the switch 5 and turning on the wireless sensor. The wireless sensor sends a wireless signal to an external monitoring terminal such as an intelligent control cabinet, and displays the switch status of each detection nut 4 on the touch screen of the intelligent control cabinet. When removing the T-bolt, the detection nut 4 is first unscrewed, and then the bolt 3 is rotated 90° and taken out. When the detection nut 4 is unscrewed, the switch 5 is turned off, and the wireless sensor stops sending wireless signals to the intelligent control cabinet. The status of the corresponding detection nut 4 on the touch screen of the intelligent control cabinet changes to "removed". The staff can understand the status of all detection nuts 4 through the touch screen, thereby judging whether the bolt 3 has been removed, avoiding damage to the groove caused by demolding of the trolley when the bolt is missed, and improving the stability of the demolding work. The staff only needs to remotely monitor through the intelligent control cabinet, which greatly reduces the workload of the staff and improves the work efficiency.

[0023] The intelligent control cabinet, touch screen, wireless sensor, built-in battery, etc. used in this application are all commonly used electronic components in the prior art. Their specific structures, working principles, circuit connections, etc. are all well-known technologies and will not be described in detail here.

[0024] The preferred technical solution is that the side surface of the detection nut 4 is provided with a charging interface 11 electrically connected to the built-in battery. The charging interface 11 is a Type-C interface, which is more convenient for charging. The battery can be recharged through a mobile phone charger, and the battery can be on standby for 30 days after a single charge. The charging interface 11 can also be a data transmission interface, so as to realize the recording and storage of the detection data, and the stored data can be retrieved through a USB flash drive.

[0025] According to a preferred technical solution, a gasket 6 is sleeved on the outer side of the bolt 3 and is arranged between the detection nut 4 and the trolley panel 1. The gasket 6 is used to protect the detection nut 4, the trolley panel 1 and the surface of the switch 5 to prevent the switch 5 from being worn or damaged due to continuous friction with the trolley panel 1 during the tightening of the detection nut 4.

[0026] A further preferred technical solution is that a mounting groove 9 is provided on the side surface of the detection nut 4 close to the trolley panel 1, and a support rod 7 is slidably arranged in the mounting groove 9. A through hole 8 corresponding to the support rod 7 is provided on the side surface of the gasket 6. The top end of the support rod 7 passes through the through hole 8 and contacts the side surface of the trolley panel 1. A spring 10 is sleeved on the outer side of the support rod 7. In the process of tightening the detection nut 4 onto the bolt 3, the top end of the support rod 7 is always against the trolley panel 1 under the action of the spring 10, thereby playing a supporting role, isolating the switch 5 from the trolley panel 1, and reducing the friction between the switch 5 and the trolley panel 1 during the tightening of the detection nut 4, thereby extending the service life of the device.

[0027] Optionally, the end of the support rod 7 is hemispherical, which can reduce the friction resistance between the support rod 7 and the trolley panel 1, making it more convenient and labor-saving to tighten the detection nut 4.

[0028] Optionally, a ball groove is opened on the upper surface of the end of the support rod 7, and a ball 13 is rolled in the ball groove, which can further reduce the friction resistance between the support rod 7 and the trolley panel 1 and reduce the wear on the surface of the trolley panel 1.
