Description

[Technical Field]

[0001] This utility model relates to the field of tunnel inspection, and in particular to a lifting device for a tunnel inspection robot. [Background Technology]

[0002] With the increasing sophistication of urban transportation networks and the rapid development of high-speed tunnels, the quality of tunnels directly affects their reliability during operation. Therefore, regular monitoring of urban and high-speed traffic tunnels is frequently necessary. During monitoring, if guide rails experience malfunctions such as bending or breakage, lifting devices can help maintenance personnel quickly remove the faulty guide rails and replace them promptly, or assist tunnel inspection robots in changing their vertical shooting height.

[0003] However, existing lifting devices are prone to derailment when sliding, causing tilting and instability. Furthermore, it is difficult to align the lifting guide rail with the fixed guide rail after it is raised to the correct position. This results in maintenance personnel spending a lot of time on alignment during replacement, leading to low work efficiency.

[0004] Therefore, a lifting device for a tunnel inspection robot is proposed, which can quickly change the height of the tunnel inspection robot, increase the connection stability between the fixed guide rail and the liftable guide rail, and achieve rapid alignment. [Utility Model Content]

Detailed Implementation Methods

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0043] The concepts involved in this application will first be explained with reference to the accompanying drawings. It should be noted that the following explanation of each concept is only to make the content of this application easier to understand and does not imply any limitation on the scope of protection of this application.

[0044] Example 1:

[0045] A lifting device for a tunnel inspection robot, such as Figure 1 As shown, it includes:

[0046] At least one lifting support 1 is provided, and the lifting supports 1 are symmetrically arranged. In this embodiment, there are two lifting supports 1, and the horizontal area occupied is small, so that they are less likely to obstruct vehicles traveling in narrow tunnels when used in tunnels.

[0047] At least one fixed guide rail 2; in this embodiment, there are two fixed guide rails 2.

[0048] At least one liftable guide rail 3 is detachably connected to both ends of the fixed guide rail 2. In this embodiment, there is one liftable guide rail 3, which is located between the fixed guide rails 2.

[0049] The sliding guide rail 4 is connected to the liftable guide rail 3 and moves the liftable guide rail 3 up and down to change its position. A connecting device is provided between the sliding guide rail 4 and the liftable guide rail 3 for magnetic or fixed connection. The connecting device includes a fastener plate whose two ends are respectively connected to the liftable guide rail 3 and the sliding guide rail 4. A connecting block is provided between the fastener plates, and a reinforcing block is provided above the connecting block to improve the stability of the liftable guide rail 3 moving up and down.

[0050] The sliding part 5 includes a locking component 6, a stop component 7, and a sliding component 8. The locking component 6 engages with the lifting bracket 1 to determine the final moving position of the lifting guide rail 3. The stop component 7 is located at both ends of the sliding guide rail 4 to prevent the sliding guide rail 4 from derailing. The sliding component 8 is located below the sliding guide rail 4, and the sliding component 8 uses a sliding wheel 801 or a sliding rope to drive the lifting guide rail 3 to move up and down. In this embodiment, the sliding component 8 uses the sliding wheel 801 to slide up and down, and the sliding is fast.

[0051] The positioning part 9 is connected between the fixed guide rail 2 and the liftable guide rail 3 to position the liftable guide rail 3 to one side of the fixed guide rail 2. The positioning part 9 is used to align the fixed guide rail 2 and the liftable guide rail 3.

[0052] Among them, such as Figure 2As shown, the positioning part 9 includes a first alignment member 901 disposed on the fixed guide rail 2, a second alignment member 902 disposed on the liftable guide rail 3, and a first push rod 903. The first push rod 903 is a 1000N thrust push rod. The first push rod 903 can extend into or retract from the first alignment member 901 and the second alignment member 902. The first alignment member 901, the second alignment member 902, and the first push rod 903 are on the same horizontal line. The first alignment member 901 and the second alignment member 902 are both provided with holes. A bearing seat is also provided on one side of the first alignment member 901 and the second alignment member 902. The design of the bearing seat, such as the flange part, can reduce vibration transmission. The bearing seat ensures the accurate position of the bearing on the machine and plays a precise positioning role.

[0053] When the first alignment member 901 and the second alignment member 902 are in a straight line, the first push rod 903 passes through the first alignment member 901 and the second alignment member to realize the corresponding connection between the liftable guide rail 3 and the fixed guide rail 2, thereby achieving rapid alignment and connection and improving connection efficiency.

[0054] like Figures 3 to 5 As shown, the locking assembly 6 includes a rectangular spring 601, an alignment member 602, a pusher member 603, and a second push rod 604. The alignment member 602 has a through hole 605, and the pusher member 603 exerts a pushing force on the second push rod 604. The lifting bracket 1 has a locking hole 606. The rectangular spring 601 is located on one side of the alignment member 602, and a washer is provided between the rectangular spring 601 and the alignment member 602. The washer effectively reduces the wear of the rectangular spring 601 on the alignment member 602 when it is stretched and compressed. The second push rod 604 passes through the pusher member 603, the rectangular spring 601, the alignment member 602, and the locking hole 606 in sequence to form a fixed position. When locking is achieved, the pusher member exerts a pushing force on the second push rod 604, and then the second push rod 604 passes through the alignment member 602 and the locking hole 606 in sequence to achieve efficient locking.

[0055] like Figure 6 As shown, the sliding assembly 8 is L-shaped and hollow inside. One end supports the sliding guide rail 4, which improves the engagement stability of the sliding guide rail 4. It is equipped with at least one sliding wheel 801 inside. A fixing plate 802 is provided on the outside of the sliding wheel 801. The fixing plate 802 is provided with at least one fastener 803 connected to the sliding wheel 801. The fastener 803 also serves as the central rotation axis of the sliding wheel 801, which achieves two purposes at once, providing both a fixing function and serving as the rotation center.

[0056] The positioning part 9 also includes at least one limiting component 904, which is located at one end of the first push rod 903. The limiting component 904 includes a first connecting plate 905, on which at least one inclined first waist hole 906 is provided. A fixing member 907 passes through the first waist hole 906. A second connecting plate 908 is located below the fixing member 907, on which a second waist hole 909 is provided. One end of the second connecting plate 908 is rotatably connected to the fixing member 907, and the other end is slidably connected to the first push rod 903 through the second waist hole 909 via a sliding riveting member 910. When the first push rod 903... When the first alignment member 901 is pushed forward, the sliding riveting member 910 is driven by the first push rod 903 to rotate to the left, forming a rightward pulling force on the first push rod 903 to prevent the first push rod 903 from being pushed too far and causing an imbalance in the center of gravity. When the first push rod 903 moves away from the first alignment member 901, the sliding riveting member 910 is driven by the first push rod 903 to rotate to the right, forming a leftward pulling force on the first push rod 903, which plays a buffering role. At the same time, it guides the entry and exit of the first push rod 903 to prevent the first push rod 903 from being misaligned and causing an impact on the first alignment member 901 and the second alignment member 902.

[0057] The fastener 907 includes a reinforcing rib 9071, a first cylindrical member 9072, and a second cylindrical member 9073. A gasket 9074 is provided between the first cylindrical member 9072 and the reinforcing rib 9071. The gasket 9074 increases the tightness of the connection between the first cylindrical member 9072 and the reinforcing rib 9071. The second cylindrical member 9073 is fastened to the first connecting plate 905, which further consolidates the connection between the first connecting plate 905 and the reinforcing rib 9071.

[0058] The first push rod 903 reciprocates along the length of the liftable guide rail 3, and the second cylindrical part 9073 is connected by bolt thread, resulting in a high degree of connection tightness.

[0059] A Hall sensor 10 is provided between the first connecting plate 905 and the second connecting plate 908. When the first connecting plate 905 and the second connecting plate 908 are misaligned, the Hall sensor 10 fails to detect a signal or the signal is weak, and outputs a high level or a low level. When the first connecting plate 905 and the second connecting plate 908 are aligned, the Hall sensor 10 detects a signal and outputs a low level or a high level, thereby determining whether the first connecting plate 905 and the second connecting plate 908 are aligned.

[0060] The upper end of the alignment member 602 is provided with a corresponding adjustable upper limit hard position member 11, which effectively sets the maximum height position of the sliding guide rail 4 to prevent the sliding guide rail 4 from sliding out. A proximity switch 12 is provided on one side of the alignment member 602. The proximity switch 12 has a similar function to the Hall sensor 10. When the sliding guide rail 4 and the alignment member 602 are not in a close state, the proximity switch 12 fails to detect a signal or the signal is weak, and outputs a high level or a low level. When the sliding guide rail 4 and the alignment member 602 are in a close state, the proximity switch 12 detects a signal and outputs a low level or a high level, thereby determining whether the sliding guide rail 4 and the alignment member 602 are close, effectively preventing the sliding guide rail 4 from sliding out and causing an accident.

[0061] The lower end of the fixed support is provided with an auxiliary support 13, which includes a triangular plate 1301 and two connecting pieces 1302. The triangular plate 1301 is located between the connecting pieces 1302. The triangular plate has the strongest stability and forms a supporting force to prevent the lifting bracket 1 from collapsing.

[0062] A method for raising a tunnel inspection robot, applied to the aforementioned tunnel inspection robot lifting device, includes the following steps:

[0063] Step 1: Turn on the power switch;

[0064] Step 2: Mount the tunnel inspection robot onto the liftable guide rail 3;

[0065] Step 3: Press the up button;

[0066] Step 4: The lifting device automatically completes the raising and pushes out the first push rod 903, completing the docking of the liftable guide rail 3 and the fixed guide rail 2;

[0067] Step 5: Control the movement of the tunnel inspection robot via remote control or backend control to enter the fixed guide rail 2.
