Description

Technical Field

[0001] This utility model relates to the field of railway construction technology, specifically to an early warning device for preventing the leakage and dismantling of T-bolts in the secondary lining trolley channel. Background Technology

[0002] In railway tunnel construction, the contact wire channel needs to be pre-embedded in the secondary lining concrete. To ensure the positioning accuracy of the channel, rectangular holes are usually made in the formwork trolley panel, and T-bolts are used to position the pre-embedded channel through these holes. However, a significant problem exists in current construction: the T-bolts need to be removed before demolding after the secondary lining is completed. Due to the large number of T-bolts, it is very easy to miss some during construction. If the T-bolts are not completely removed, the channel will be damaged when the trolley is demolded. Repairing the damaged channel is extremely difficult and may even lead to the scrapping of some concrete and the need for reconstructing. This will seriously affect the project progress and increase construction costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an early warning device for preventing the T-bolts from being removed from the secondary lining trolley channel. The device has a simple structure, low cost, and convenient operation. Operators can accurately determine whether the channel nuts have been completely removed, avoiding channel damage caused by trolley demolding in case of missing bolts, improving the stability of demolding work, ensuring project progress, and effectively solving the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof early warning device for T-bolts in a secondary lining trolley channel, comprising a channel, T-bolts, fastening nuts, a control cabinet, a storage box, and a weighing sensor; the channel is pre-embedded in the secondary lining concrete, and the trolley panel is connected to the channel by several T-bolts and fastening nuts; the weighing sensor is installed at the bottom of the storage box, and a tray for placing the fastening nuts is provided on the weighing sensor.

[0005] Preferably, the control cabinet is equipped with a display that can display the weight of the fastening nuts on the tray in real time. The specifications and weights of the multiple fastening nuts are the same. The control cabinet is also equipped with a microprocessor, which is electrically connected to the weighing sensor and the display. The microprocessor calculates the total number of fastening nuts based on the ratio of the total weight detected by the weighing sensor to the theoretical weight of a single fastening nut, and displays it on the display.

[0006] Preferably, the storage box is also equipped with an infrared sensor counter. The control cabinet is electrically connected to the infrared sensor counter. Every time the operator puts a fastening nut into the storage box, the infrared sensor counter automatically increments by one. Every time a fastening nut is removed, the infrared sensor counter automatically decrements by one.

[0007] Preferably, the infrared sensor counter includes a pair of oppositely arranged infrared transmitters and infrared receivers, forming at least one detection plane. When an operator holds a fastening nut through the detection plane, the infrared signal is blocked, thus achieving automatic counting.

[0008] Preferably, the trolley panel has a rectangular hole, a T-bolt passes through the rectangular hole, the nut of the T-bolt is located in the channel, and the fastening nut is threadedly connected to the T-bolt, causing the trolley panel to abut against the channel.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. By installing a weighing sensor at the bottom of the storage box and using pure physical weight detection logic, the number of fastening nuts can be accurately verified. In addition, the number can also be verified by an infrared sensor counter. The two can verify each other, avoiding detection errors caused by electronic component failure or signal interference, which greatly improves the accuracy and reliability of detection. Only a weighing sensor and an infrared sensor counter need to be installed in the storage box, which greatly reduces the cost and simplifies the maintenance of the equipment, making it conducive to large-scale promotion and application. 2. Workers only need to follow the conventional construction steps to install and remove the fastening nuts and put them into the storage box. By comparing the weight and quantity displayed on the device, they can determine whether the bolts have been completely removed. The operation is simple and easy to understand, reducing the professional skills required of the workers. 3. By accurately determining whether the fastening nuts have been completely removed, since the fastening nuts and T-bolts are in a one-to-one correspondence, it is possible to determine whether the T-bolts have been completely removed. This can effectively prevent the trolley from being demolded if the bolts are not removed, thereby preventing the channel from being damaged, reducing the repair costs and project delays caused by channel damage, and ensuring the project progress and construction quality. In summary, this utility model has a simple structure, low cost, and convenient operation. It verifies the number of nuts through pure physical weight detection logic, enabling operators to accurately determine whether all nuts in the channel have been removed. This avoids damage to the channel caused by the trolley demolding if bolts are not removed, improves the stability of the demolding work, and ensures the progress of the project.

[0012] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0013] Please see Figure 1-3 The present invention provides the following technical solution: Example 1: A leak-proof early warning device for T-bolts in a secondary lining trolley channel includes a channel 1, T-bolts 2, fastening nuts 3, a control cabinet 5, a storage box 6, and a weighing sensor 7. The channel 1 is embedded in the secondary lining concrete. The trolley panel 4 is connected to the channel 1 by several T-bolts 2 and fastening nuts 3. The trolley panel 4 has a rectangular hole through which the T-bolts 2 pass. The nuts of the T-bolts 2 are located inside the channel 1. The fastening nuts 3 are threadedly connected to the T-bolts 2, causing the trolley panel 4 to abut against the channel 1. The weighing sensor 7 is located at the bottom of the storage box 6, and a tray for placing the fastening nuts 3 is provided on the weighing sensor 7. Furthermore, the control cabinet 5 is equipped with a display that can display the weight of the fastening nuts 3 on the tray in real time. The specifications and weights of the multiple fastening nuts 3 are the same. The control cabinet 5 is also equipped with a microprocessor. The microprocessor is electrically connected to the weighing sensor 7 and the display. The connection method adopts existing technology, which will not be described in detail here. The microprocessor calculates the total number of fastening nuts 3 based on the ratio of the total weight detected by the weighing sensor 7 to the theoretical weight of a single fastening nut 3, and displays it on the display. Understandably, by installing a weighing sensor 7 at the bottom of the storage box 6 and using purely physical weight detection logic, the number of fastening nuts 3 can be accurately verified, determining whether the number of collected fastening nuts 3 matches the original number of fastening nuts, and whether the fastening nuts 3 have been completely removed. Since the fastening nuts 3 and T-bolts 2 have a one-to-one correspondence, this method of determining whether the T-bolts 2 have been completely removed can effectively prevent the trolley from demolding when bolts are not removed, thereby preventing the channel from being damaged, reducing repair costs and project delays caused by channel damage, and ensuring project progress and construction quality.

[0014] Example 2: Unlike Example 1, the storage box 6 is also equipped with an infrared sensor counter 8. The control cabinet 5 is electrically connected to the infrared sensor counter 8. Every time the operator puts a fastening nut 3 into the storage box 6, the infrared sensor counter 8 automatically increments by one. Every time a fastening nut 3 is taken out, the infrared sensor counter 8 automatically decrements by one. Specifically, the infrared sensor counter 8 includes a pair of infrared transmitters and receivers arranged opposite to each other, forming at least one detection plane. When the operator holds the fastening nut 3 through the detection plane, the infrared signal is blocked, thus achieving automatic counting. The infrared sensor counter 8 can also count the number of fastening nuts 3 that are picked up and put down. It can be used as a backup when the weighing sensor 7 fails. It can also be used to cross-verify the number of fastening nuts 3 measured by the weighing sensor 7 and the microprocessor to ensure the authenticity and accuracy of the data.

[0015] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents in the content of this utility model.
