Description
Technical Field
[0001] This utility model relates to the field of construction monitoring technology, and in particular to a mobile construction monitoring device for tunnel railway engineering. Background Technology
[0002] In recent years, with the rapid development of the social economy and increased exchanges, the requirements for transportation construction have become increasingly higher. Railway engineering, as a major means of supporting long-distance transportation, has developed rapidly. During the construction of tunnel railway projects, it is necessary to monitor the deformation of the surrounding rock. At this time, a visual displacement monitoring instrument is required, which is mainly used to monitor the deformation and displacement of the structure under stress or environmental factors.
[0003] When using a visual displacement monitor, a measurement target must first be installed on the surface of the object being measured. The machine vision camera captures the image of the target, and the sub-pixel image displacement of the target is identified by an intelligent algorithm. Finally, the image displacement is converted into physical space displacement using a self-calibration matrix algorithm to obtain the actual displacement of the target. The data is uploaded to a cloud platform via the network to achieve non-contact measurement of structural displacement. However, existing visual displacement monitors are fixed to the walls inside tunnels, which is troublesome to install and remove, thus increasing the difficulty of the work for the staff. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a mobile monitoring device for tunnel and railway engineering construction.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mobile tunnel railway engineering construction monitoring device, including a support rod, an installation box installed on the outer wall of the support rod, a storage battery installed inside the installation box, an installation component fixedly installed on the upper surface of the support rod, a visual displacement monitor installed on the installation component, the visual displacement monitor being electrically connected to the storage battery, three support legs installed on the bottom surface of the support rod, a support seat installed at the end of each of the three support legs away from the support rod, and a caster wheel installed on each of the three support seats.
[0006] By adopting the above technical solution, when workers need to monitor the construction site inside the tunnel, they need to install the target on the point to be measured inside the tunnel. Then, workers push the main body of the device into the tunnel using casters, allowing the visual displacement monitor on the main body of the device to monitor the target and thus monitor the displacement of the tunnel. During this process, the main body of the device can move freely, thereby reducing the difficulty for workers in installing the displacement monitor and consequently reducing the workload of the workers.
[0007] Furthermore, each of the three support bases has a sliding groove on its bottom surface, and a sliding member is slidably disposed in the sliding groove. The universal wheel is fixed to the sliding member, and a control component for controlling the sliding member is disposed in the sliding groove.
[0008] By adopting the above technical solution, after the staff pushes the main body of the device into the tunnel through the casters, the staff needs to control the sliding parts to slide upward through the control components, so that the casters move upward under the action of the sliding parts, and thus the casters move into the chute. In this process, the casters move into the chute, which reduces the probability of the main body of the device moving during use, thereby improving the stability of the device.
[0009] Furthermore, the control component includes a first connector fixedly disposed on the upper surface of the slider and a second connector slidably disposed in the groove. A first inclined surface is formed on the edge of the upper surface of the first connector where it intersects with the side wall of the second connector, and a second inclined surface is formed on the edge of the bottom surface of the second connector where it intersects with the side wall of the first connector.
[0010] Furthermore, a rotating groove is provided on the side wall of the support base, and a threaded rod is rotatably disposed in the rotating groove, the threaded rod being threadedly connected to the second connecting member.
[0011] By adopting the above technical solution, when the worker needs to move the caster wheel outside the slide groove using the control component, the worker needs to rotate the threaded rod, which causes the second connecting member to move closer to the first connecting member under the action of the threaded rod. At this time, because the first inclined surface and the second inclined surface abut against each other, the first connecting member slides downward under the action of the second connecting member, which in turn causes the sliding member to slide downward under the action of the first connecting member, thereby causing the caster wheel to move downward under the action of the sliding member, thus moving the caster wheel outside the slide groove. This reduces the difficulty for the worker to move the caster wheel, thereby reducing the difficulty of the worker's work.
[0012] Furthermore, an annular groove is formed on the inner wall of the rotating groove, and an annular block is rotatably arranged in the annular groove, the annular block being fixed to the threaded rod.
[0013] By adopting the above technical solution, when the operator rotates the threaded rod, the annular block rotates under the action of the threaded rod. During this process, the annular block reduces the probability of the threaded rod moving, thereby reducing the probability of the second connecting part moving, thus improving the stability of the device.
[0014] Furthermore, symmetrical limiting grooves are formed on the inner top wall of the slide groove, and limiting rods are slidably arranged in both limiting grooves, with both limiting rods being fixed to the sliding member.
[0015] Furthermore, a reset spring is fixedly provided on the upper surface of each of the two limiting rods, and the other end of each of the two reset springs is fixedly provided on the inner top wall adjacent to the limiting groove.
[0016] By adopting the above technical solution, when the slider slides, the limiting rod slides under the action of the slider. During this process, the limiting rod reduces the probability of the slider wobbling during sliding, thereby improving the stability of the device. In addition, the return spring reduces the probability of the slider moving downward under the action of gravity, thereby improving the stability of the device.
[0017] Furthermore, the bottom surface of the support base is arrayed with multiple protrusions.
[0018] By adopting the above technical solution, the protrusion increases the roughness of the bottom surface of the support base, thereby further reducing the probability of movement of the main body of the device during use, and thus improving the stability of the device.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. In this application, when workers need to monitor the construction site inside the tunnel, they need to install the target on the point to be measured inside the tunnel. Subsequently, the workers push the main body of the device into the tunnel using casters, so that the visual displacement monitoring instrument on the main body of the device can monitor the target, thereby monitoring the displacement of the tunnel. During this process, the main body of the device can move freely, which reduces the difficulty for workers to install the displacement monitoring instrument and thus reduces the difficulty of their work.
[0021] 2. In this application, after the staff pushes the main body of the device into the tunnel through the casters, the staff needs to control the sliding parts to slide upward through the control components, so that the casters move upward under the action of the sliding parts, and thus the casters move into the chute. In this process, the casters move into the chute, which reduces the probability of the main body of the device moving during use, thereby improving the stability of the device.
[0022] 3. In this application, when the worker needs to move the caster wheel outside the slide groove using the control component, the worker needs to rotate the threaded rod, which causes the second connecting member to move closer to the first connecting member under the action of the threaded rod. At this time, since the first inclined surface and the second inclined surface abut against each other, the first connecting member slides downward under the action of the second connecting member, which in turn causes the sliding member to slide downward under the action of the first connecting member, thereby causing the caster wheel to move downward under the action of the sliding member, thus moving the caster wheel outside the slide groove. This reduces the difficulty for the worker to move the caster wheel, thereby reducing the difficulty of the worker's work. Attached Figure Description

[0028] The technical solutions in 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. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] like Figure 1-4 As shown in the figure, this application discloses a mobile tunnel railway engineering construction monitoring device, including a support rod 1, a mounting box 11, a mounting component 12, a visual displacement monitor 13, support legs 14, support seats 15, casters 16, a sliding component 21, a control component 3, a threaded rod 41, an annular block 51, a limiting rod 61, and a return spring 7. The support rod 1 is a cylindrical rod structure with a vertical axis. The mounting box 11 is installed on the outer wall of the support rod 1, and a battery (not shown in the figure) is installed inside the mounting box 11. The mounting component 12 is fixedly installed on the upper surface of the support rod 1, and the visual displacement monitor 13 is installed on the mounting component 12 and electrically connected to the battery. The support legs 14 are cylindrical rod structures, and multiple support legs 14 are provided and installed on the bottom surface of the support rod 1. The support seats 15 are cuboid structures, and multiple support seats 15 are provided and respectively installed on the ends of multiple support legs 14 away from the support rod 1. Multiple casters 16 are provided and respectively installed on multiple support seats 15.
[0030] When workers need to monitor the construction site inside the tunnel, they must install the target at the point to be measured inside the tunnel. Then, the main body of the device is pushed into the tunnel using the casters 16, allowing the visual displacement monitor 13 on the main body to monitor the target and thus monitor the tunnel's displacement. During this process, the main body of the device can move freely, reducing the difficulty of installing the displacement monitor and consequently lowering the workload for the workers.
[0031] The bottom surfaces of the three support bases 15 are all provided with sliding grooves 2, and multiple sliding members 21 are provided and are slidably disposed in the multiple sliding grooves 2 respectively, and the casters 16 are fixed to the sliding members 21.
[0032] After the staff pushes the main body of the device into the tunnel using the casters 16, the staff needs to control the sliding member 21 to slide upward using the control component 3. This causes the casters 16 to move upward under the action of the sliding member 21, thus moving the casters 16 into the chute 2. During this process, the casters 16 move into the chute 2, reducing the probability of the main body of the device moving during use, thereby improving the stability of the device.
[0033] The control component 3 is disposed within the slide groove 2 and is used to control the sliding of the slider 21. The control component 3 includes a first connector 31 and a second connector 32. The first connector 31 is fixedly disposed on the upper surface of the slider 21, and the second connector 32 is slidably disposed within the slide groove 2. A first inclined surface 33 is formed on the edge of the upper surface of the first connector 31 where it intersects with the side wall of the second connector 32, and a second inclined surface 34 is formed on the edge of the bottom surface of the second connector 32 where it intersects with the side wall of the first connector 31.
[0034] A rotating groove 4 is provided on the side wall of the support base 15. The threaded rod 41 is rotatably disposed in the rotating groove 4 with its axis horizontal, and the threaded rod 41 is threadedly connected to the second connecting member 32.
[0035] When the operator needs to move the caster wheel 16 outside the slide groove 2 using the control component 3, the operator needs to rotate the threaded rod 41, which causes the second connecting member 32 to move closer to the first connecting member 31 under the action of the threaded rod 41. At this time, since the first inclined surface 33 and the second inclined surface 34 abut against each other, the first connecting member 31 slides downward under the action of the second connecting member 32, which in turn causes the sliding member 21 to slide downward under the action of the first connecting member 31, thereby causing the caster wheel 16 to move downward under the action of the sliding member 21, thus moving the caster wheel 16 outside the slide groove 2. This reduces the difficulty for the operator to move the caster wheel 16, thereby reducing the difficulty of the operator's work.
[0036] An annular groove 5 is provided on the inner wall of the rotating groove 4. The annular block 51 is rotatably disposed in the annular groove 5, and its axis coincides with the axis of the threaded rod 41. The annular block 51 and the threaded rod 41 are fixed to each other.
[0037] When the operator rotates the threaded rod 41, the annular block 51 rotates under the action of the threaded rod 41. During this process, the annular block 51 reduces the probability of the threaded rod 41 moving, thereby reducing the probability of the second connecting piece 32 moving, thus improving the stability of the device.
[0038] The inner top wall of the slide groove 2 is symmetrically provided with limiting grooves 6. The limiting rod 61 is a round rod structure with its axis vertical. There are two limiting rods 61, which are slidably arranged in the two limiting grooves 6 respectively. Both limiting rods 61 are fixed to the sliding member 21.
[0039] Two reset springs 7 are provided. One end of each reset spring 7 is fixedly mounted on the upper surface of the two limit rods 61, and the other end of each reset spring 7 is fixedly mounted on the inner top wall adjacent to the limit groove 6.
[0040] When the slider 21 slides, the limiting rod 61 slides under the action of the slider 21. During this process, the limiting rod 61 reduces the probability of the slider 21 wobbling during sliding, thereby improving the stability of the device. In addition, the return spring 7 reduces the probability of the slider 21 moving downward under the action of gravity, thereby improving the stability of the device.
[0041] To improve the stability of the device, the bottom surface of the support base 15 is arrayed with multiple protrusions. The protrusions increase the roughness of the bottom surface of the support base 15, thereby further reducing the probability of movement of the main body of the device during use, and thus improving the stability of the device.
[0042] The operating principle of the mobile tunnel railway engineering construction monitoring equipment in this embodiment is as follows: When workers need to monitor the construction site inside the tunnel, they need to install a target on the point to be measured inside the tunnel. Subsequently, the workers push the main body of the device into the tunnel using the casters 16, allowing the visual displacement monitor 13 on the main body of the device to monitor the target, thereby monitoring the displacement of the tunnel. During this process, the main body of the device can move freely, thus reducing the difficulty for workers to install the displacement monitor and consequently reducing the workload of the workers.
[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
