Description

Technical Field

[0001] This utility model relates to the field of inspection equipment technology, specifically to a tunnel inspection trolley. Background Technology

[0002] Chinese patent application number 202420049902.3 discloses an automatic tunnel inspection vehicle, including a vehicle body and a camera device. The camera device is mounted on the upper part of the vehicle body, and an anti-collision mechanism is provided on the vehicle body. An ultrasonic sensor is fixedly installed on the front of the vehicle body. The anti-collision mechanism includes a first corner bracket and a mounting base. The mounting base has a guide hole, and a guide post is inserted into the guide hole. This invention, by setting an anti-collision mechanism on the vehicle body, causes its rubber roller to rotate when the tunnel wall comes into contact with the wall, thereby reducing friction. Simultaneously, the first corner bracket moves closer to the mounting base, and its buffer spring is compressed to provide cushioning, thus protecting the corners of the vehicle body. Additionally, its guardrail provides some protection to the front of the vehicle body, improving the service life of the automatic tunnel inspection vehicle.

[0003] However, the Chinese patent with application number 202420049902.3 has a limited function. In daily use, the driving speed of the Chinese patent with application number 202420049902.3 would limit its use in tunnels.

[0004] However, there is space at the top of the tunnel. For example, Chinese Patent Application No. 201821846912.0 discloses an inspection device for environmental monitoring of cable tunnels, which includes a main inspection structure, a track plate, and electric rollers. The upper end of the main inspection structure is connected to a vertical plate, and the inner side of the vertical plate is connected to a central shaft. Two electric rollers are provided, each sleeved on the central shaft. The track plate has two tracks, and the upper end of the track plate is fixedly connected to the upper side wall of the cable tunnel by multiple hanging rods. The main inspection structure contains a battery device and a main control device. The outer side of the main inspection structure is connected to a temperature detection device and a humidity detection device. A rotating camera device is sleeved on a connecting rod connected to the lower end of the main inspection structure. The beneficial effects of this utility model are: the automatic inspection vehicle is placed on the track plate, and the automatic inspection vehicle moves on the track plate, monitoring the temperature and humidity inside the cable tunnel online during the movement, greatly reducing the workload; the rotating camera device can capture monitoring images in real time, making it convenient for personnel in the machine room to intuitively view the inside of the tunnel.

[0005] However, the Chinese patent walking mechanism with application number 201821846912.0 is relatively simple and not suitable for widespread use.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0025] like Figures 1 to 2 As shown, the tunnel inspection trolley of this utility model includes: a mounting frame 1, a fixed plate 2 and a traveling mechanism 3 mounted on the mounting frame 1; the traveling mechanism 3 drives the mounting frame 1 to move. Specifically, a cable is fixedly installed on the top of the tunnel, and the traveling mechanism 3 is suspended on the cable, thereby driving the mounting frame 1 to move.

[0026] The fixing plate 2 has several through holes for installing electronic components, such as cameras.

[0027] To ensure safety and prevent falls, the walking mechanism 3 in this application is provided with two sets. The walking mechanism 3 includes: a base 31, a walking motor 32 fixedly installed on the base 31, and an active walking wheel 33 and a passive walking wheel 34 rotatably installed on the base 31. An active gear 35 is installed on the output shaft of the walking motor 32, and a passive gear 36 is installed at the end of the active walking wheel 33. The active gear 35 and the passive gear 36 mesh, so that when the walking motor 32 rotates actively, it can drive the active walking wheel 33 to rotate through the active gear 35 and the passive gear 36. The active walking wheel 33 and the passive walking wheel 34 contact the cable, thereby actively moving along the cable.

[0028] It should be noted that there are two active walking wheels 33. When the walking motor 32 drives the active gear 35 to rotate, the two passive gears 36 rotate synchronously, so that it can actively move along the cable.

[0029] To accommodate cables of different widths, an adjustment component 37 is provided between the two bases 31, which can flexibly change the spacing between the two cables to adapt to different situations.

[0030] The adjustment assembly 37 includes: an adjustment motor 371, and a threaded rod 372 connected to the output shaft of the adjustment motor 371. The threaded rod 372 is threadedly connected to the base 31, and the thread on the threaded rod 372 is a forward and reverse thread. That is to say, when the adjustment motor 371 drives the threaded rod 372 to rotate, the two bases 31 can move closer or further apart synchronously, thereby flexibly changing the spacing between the two cables to adapt to different situations.

[0031] The adjusting motor 371 is fixedly mounted on the mounting bracket 1. A guide rod 373 is fixedly mounted on the mounting bracket 1. The guide rod 373 passes through the seat 31 and slides in contact with it. The guide rod 373 plays a good guiding role in the movement of the seat 31, so that the seat 31 can move stably along the axial direction of the guide rod 373.

[0032] It should be noted that a motor mounting base 374 is fixedly installed at one end of the mounting bracket 1, the adjusting motor 371 is fixedly installed on the motor mounting bracket, and one end of the threaded rod 372 is installed on the mounting bracket 1 through the mounting base 375.

[0033] The through holes of the fixing plate 2 can be used to pass fasteners, thereby fixing electronic components. Multiple through holes are provided to facilitate users to flexibly select appropriate electronic components as needed. Of course, it is also possible not to provide through holes. Through holes only serve a convenient purpose. For those skilled in the art, there are many ways to install electronic components on the fixing plate 2, which will not be elaborated in this application.

[0034] The fixing plate extends laterally into the mounting frame 1 to form a connecting plate 4, which is fixedly mounted to the mounting frame 1 by bolts.

[0035] A connecting rod 5 is fixedly connected to the connecting plate 4, and a bushing 6 is fixedly connected to one end of the connecting rod 5. The bushing 6 is sleeved on the cable. The bushing 6 serves to prevent the cable from falling. When the cable detaches from the active walking wheel 33 and the passive walking wheel 34, the cable will come into contact with the bushing 6. At this time, the walking motor 32 is turned off to prevent further accidents.

[0036] A contact ring 7 is fixedly installed inside the bushing 6. The contact ring 7 is made of Teflon material. The inner diameter of the contact ring 7 is larger than the diameter of the cable. That is to say, the cable generally does not contact the contact ring 7. When they do contact, the Teflon material can play a lubricating role to prevent sliding friction between the bushing 6 and the cable.

[0037] Working principle:

[0038] When the walking motor 32 rotates actively, it can drive the active walking wheel 33 to rotate through the active gear 35 and the passive gear 36. The active walking wheel 33 and the passive walking wheel 34 are in contact with the cable, so they can move actively along the cable.

[0039] When the adjusting motor 371 drives the threaded rod 372 to rotate, the two seats 31 can move closer or further apart synchronously, thereby flexibly changing the spacing between the two cables to adapt to different situations.

[0040] When the cable detaches from the active walking wheel 33 and the passive walking wheel 34, the cable will come into contact with the bushing 6. At this time, the walking motor 32 is turned off to prevent further accidents. The Teflon material can play a lubricating role to avoid sliding friction between the bushing 6 and the cable.

[0041] All standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be detailed here. Contents not described in detail in this specification belong to the prior art known to those skilled in the art. It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
