Description

Technical Field

[0001] This utility model belongs to the technical field of inspection and maintenance vehicles, and specifically relates to a track slab inspection and maintenance vehicle. Background Technology

[0002] Track slabs are reinforced concrete slabs used for the installation of high-speed railway tracks. After installation, track slabs require regular compressive strength inspection and maintenance during long-term use. These inspection and maintenance are usually carried out by inspection and maintenance vehicles. Existing inspection and maintenance vehicles are designed for inspecting and maintaining reinforced concrete slabs used for the installation of high-speed railway tracks. They are easy to move to the inspection location by means of track wheels on the track surface, making inspection and maintenance convenient.

[0003] Existing inspection and maintenance vehicles, when inspecting the compressive strength of concrete slabs installed on high-speed railway tracks, require the vehicle to be positioned on the upper surface of the track and moved to the concrete slab to be inspected. The support plate is then opened to contact the ground for support, and a hydraulic cylinder lowers the compressive strength testing column for testing. This method makes it difficult to reinforce the vehicle when it is positioned on the upper surface of the track. Furthermore, the downward movement of the testing column to the surface of the concrete slab generates external force, which can cause instability in the vehicle, leading to inaccurate compressive strength testing, tilting, and potential hazards. This compromises the vehicle's ability to effectively reinforce concrete slabs installed on high-speed railway tracks. Therefore, this invention proposes a new track slab inspection and maintenance vehicle. Utility Model Content

[0004] The purpose of this utility model is to provide a track slab inspection and maintenance vehicle to solve the problems mentioned in the background art, such as the inconvenience of reinforcing the inspection and maintenance vehicle when it is placed on the upper surface of the track, the external force generated when the pressure testing plate moves down to the surface of the concrete slab, the instability of the inspection and maintenance vehicle under the external force, and the inaccuracy and skewness during pressure testing and maintenance, which may lead to danger.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a track slab inspection and maintenance vehicle, comprising an inspection and maintenance vehicle body, the inspection and maintenance vehicle body including a counterweight base, two track wheels being provided at the corner positions of the lower surface of the counterweight base, support plates being mounted on both ends of the lower surface of the counterweight base via cylinders, a push plate being mounted on a track at one end of the upper surface of the counterweight base, a housing being fixed to one side of the push plate on the upper surface of the counterweight base, an inspection display instrument being provided on the upper surface of the housing, and the inspection and maintenance vehicle body also including:

[0006] A reinforcement installation mechanism, comprising a rotation adjustment component disposed at the middle position inside the counterweight base, wherein the two ends of the rotation adjustment component are provided with reinforcement installation components inside the counterweight base, and the ends of the reinforcement installation components are provided with limit components;

[0007] A buffer protection mechanism, comprising a buffer protection component disposed on the outer surface of the inspection display, wherein a control component is disposed on the inner surface of the buffer protection component.

[0008] Preferably, a hydraulic cylinder is installed inside the housing via a support frame. A pressure sensor is fixedly installed at the end of the hydraulic cylinder inside the support frame via bolts. A pressure resistance inspection column is fixedly installed on the lower surface of the pressure sensor, and the pressure resistance inspection column passes through the interior of the counterweight base. The pressure sensor is electrically connected to the inspection display via a wire.

[0009] Preferably, the rotation adjustment assembly includes a bidirectional lead screw that rotates at the middle position inside the counterweight base, a handwheel is installed at the end of the bidirectional lead screw on the side of the counterweight base, and movable seats are provided at both ends of the bidirectional lead screw.

[0010] Preferably, a locking bolt is threaded on one side of the handwheel, and internal threaded holes are provided at equal intervals on the side of the counterweight base and the edge of the handwheel.

[0011] Preferably, the reinforcement mounting assembly includes two mounting slots formed at both ends of the lower surface of the counterweight base, and the inside of the mounting slots is provided with an anti-slip reinforcement plate. The end of the movable seat is fixed to the top side of the anti-slip reinforcement plate by welding.

[0012] Preferably, the limiting component includes a limiting groove formed on one side of the mounting groove, a limiting slider is fixed on the other side of the anti-slip reinforcement plate, and the limiting slider is slidably connected to the inside of the limiting groove.

[0013] Preferably, the buffer protection assembly includes a protective cover disposed on the outer surface of the inspection display, and the protective cover is fixed to the surface of the housing by screws. A buffer groove is formed on the upper surface of the protective cover, and a buffer plate is disposed inside the buffer groove.

A spring is welded at the connection between the inner surface of the buffer plate and the inner surface of the buffer groove.

[0014] Preferably, the control component includes control slide rods welded to both sides of the inner surface of the buffer plate, control hollow plates are welded to both sides of the protective cover, and the control slide rods pass through the interior of the control hollow plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By designing a reinforced installation mechanism, when the main body of the inspection and maintenance vehicle is moved to the concrete slab of the track requiring pressure resistance inspection and maintenance, the two moving seats can be moved towards each other, causing the anti-slip reinforcement plates to move stably inside the installation groove. This, in turn, causes both sets of anti-slip reinforcement plates to move towards each other and reinforce and clamp onto the side of the track, ensuring that the main body of the inspection and maintenance vehicle is reinforced and installed at the inspection point. Furthermore, it is less likely to cause instability when the pressure resistance inspection column is lowered to test the force. The reinforced inspection and maintenance results are more accurate and safer to operate, improving the reinforcement and accuracy of the inspection and maintenance vehicle when performing pressure resistance inspection and maintenance on the concrete slab of the high-speed rail track.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a track slab inspection and maintenance vehicle, including a vehicle body 100, a counterweight base 101, two track wheels 102 at the corners of the lower surface of the counterweight base 101, support plates 103 mounted on both ends of the lower surface of the counterweight base 101 via cylinders, a push plate 106 mounted on a track at one end of the upper surface of the counterweight base 101, a housing 104 fixed to one side of the push plate 106 on the upper surface of the counterweight base 101, an inspection display 105 mounted on the upper surface of the housing 104, and a hydraulic cylinder 107 mounted inside the housing 104 via a support frame, the end of the hydraulic cylinder 107 being fixed inside the support frame by bolts. A pressure sensor 109 is provided, and a pressure testing column 108 is fixedly installed on the lower surface of the pressure sensor 109. The pressure testing column 108 penetrates the interior of the counterweight base 101, and the pressure sensor 109 is electrically connected to the inspection display instrument 105 via a wire. When the inspection and maintenance vehicle body 100 is positioned at the inspection and maintenance track plate and energized, the hydraulic cylinder 107 moves, causing the pressure testing column 108 to move downwards via the pressure sensor 109 until the bottom end of the pressure testing column 108 contacts the surface of the concrete track mounting plate. Further downward movement is performed to conduct pressure checks at different levels. During the downward pressure detection, the pressure sensor 109 receives pressure and transmits it again to the inspection display instrument 105 for display. The inspection and maintenance vehicle body 100 is also equipped with:

[0026] The reinforcement installation mechanism includes a rotation adjustment component located at the middle position inside the counterweight base 101. The two sides of the rotation adjustment component are equipped with reinforcement installation components inside the counterweight base 101. The ends of the reinforcement installation components are equipped with limit components. The inspection and maintenance vehicle body 100 can be moved on the track to the concrete slab used for the inspection and maintenance track installation. The reinforcement installation mechanism can then reinforce and perform inspection and maintenance on the inspection and maintenance vehicle body 100, making the inspection more stable and accurate.

[0027] To facilitate simultaneous adjustment of the four anti-slip reinforcement plates 1011 via the rotation adjustment assembly, and to simplify adjustment and reinforcement installation, in this embodiment, preferably, the rotation adjustment assembly includes a bidirectional lead screw 1015 rotatably positioned at the center of the counterweight base 101. A handwheel 1018 is mounted at the end of the bidirectional lead screw 1015 on the side of the counterweight base 101, allowing the hand to be held and rotated to facilitate adjustment. Movable seats 10 are provided at both ends of the bidirectional lead screw 1015. 16. When the bidirectional lead screw 1015 is rotated, it drives the two moving seats 1016 to move towards each other, so as to facilitate the simultaneous adjustment and reinforcement installation of the four anti-slip reinforcement plates 1011. The handwheel 1018 has a locking bolt 1017 on one side of its threaded rotation. The side of the counterweight base 101 and the edge of the handwheel 1018 are provided with internal threaded holes 1019 at equal intervals. After adjustment and reinforcement installation, the locking bolt 1017 is rotated to insert into the internal threaded hole 1019 to reinforce the handwheel 1018 and the bidirectional lead screw 1015 and prevent rotation under force.

[0028] In order to facilitate the reinforcement of the inspection and maintenance vehicle body 100 for stable inspection and maintenance at the inspection and maintenance site by means of the reinforcement installation component, in this embodiment, preferably, the reinforcement installation component includes two installation grooves 1012 formed at both ends of the lower surface of the counterweight base 101. The anti-slip reinforcement plate 1011 is provided inside the installation groove 1012. The end of the movable seat 1016 is fixed to the top side of the anti-slip reinforcement plate 1011 by welding. When the movable seat 1016 moves, it can drive the anti-slip reinforcement plate 1011 to move stably inside the installation groove 1012 until the anti-slip reinforcement plate 1011 is clamped and fixed to the side of the high-speed rail track for reinforcement installation, which facilitates the reinforcement of the inspection and maintenance concrete slab.

[0029] In order to facilitate the stable movement and adjustment of the anti-slip reinforcement plate 1011 by means of the limiting component, in this embodiment, preferably, the limiting component includes a limiting slide groove 1013 formed on one side of the mounting groove 1012, and a limiting slider 1014 fixed on the other side of the anti-slip reinforcement plate 1011, and the limiting slider 1014 is slidably connected to the inside of the limiting slide groove 1013, so that the limiting slider 1014 can slide inside the limiting slide groove 1013 when the anti-slip reinforcement plate 1011 moves, which facilitates sliding adjustment.

[0030] The buffer protection mechanism includes a buffer protection component disposed on the outer surface of the inspection display 105. The inner surface of the buffer protection component is provided with a control component. When the inspection and maintenance vehicle body 100 is inspected and maintained on the track, the buffer protection mechanism can buffer and protect the outer surface of the inspection display 105, which is convenient for protection and inspection and maintenance.

[0031] To facilitate the protection of the outer surface of the inspection display 105 using a buffer protection assembly, in this embodiment, preferably, the buffer protection assembly includes a protective cover 1051 disposed on the outer surface of the inspection display 105, and the protective cover 1051 is fixed to the surface of the housing 104 by screws, so as to facilitate the protection of the outer surface of the housing 104 by the protective cover 1051. A buffer groove 1053 is formed on the upper surface of the protective cover 1051, and a buffer plate 1052 is disposed inside the buffer groove 1053. Rubber buffer plates 1054 are fixed to the lower surfaces of both ends of the buffer plate 1052 by screws. A spring 1055 is welded at the connection between the inner surface of the buffer plate 1052 and the inner surface of the buffer groove 1053. When the protective cover 1051 is protecting, when the upper surface is touched, it directly touches the outer surface of the buffer plate 1052, and the spring 1055 deforms and drives the buffer plate 1052 to buffer, so as to provide additional buffer protection while the protective cover 1051 is protecting.

[0032] In order to facilitate the stable buffering and protection of the buffer plate 1052 through the control component, in this embodiment, preferably, the control component includes control slide rods 1056 welded to both sides of the inner surface of the buffer plate 1052, and control hollow plates 1057 welded to both sides of the protective cover 1051. The control slide rods 1056 penetrate through the interior of the control hollow plates 1057, so that when the buffer plate 1052 buffers, it can drive the control slide rods 1056 to slide and stabilize the buffering control inside the control hollow plates 1057.

[0033] The working principle and usage process of this utility model are as follows: When in use, this type of track slab inspection and maintenance vehicle directly corresponds to the high-speed rail track via the track wheels 102. The track wheels 102 contact the track and roll the vehicle to the concrete slab where the track needs to be inspected and maintained under pressure. During inspection and maintenance, the main body 100 of the inspection and maintenance vehicle is powered on, and the hydraulic cylinder 107 moves to move the pressure inspection column 108 downward through the pressure sensor 109 until the bottom end of the pressure inspection column 108 contacts the surface of the concrete track installation plate. The column continues to move downward to perform pressure checks of different degrees. When the pressure is detected, the pressure sensor 109 receives pressure and transmits it again to the inspection display instrument 105 for display. This makes it convenient for the main body 100 of the inspection and maintenance vehicle to regularly inspect and maintain the concrete slabs installed on the high-speed rail track.

[0034] Then, before the inspection and maintenance vehicle body 100 is installed and used, after the inspection display 105 is on the top of the housing 104, the protective cover 1051 is fixedly installed on the outer surface of the inspection display 105 for protection. When the protective cover 1051 is in the external inspection and maintenance use, when the surface of the protective cover 1051 is touched by the outside, it directly impacts the surface of the buffer plate 1052, which puts force on the spring 1055. When the spring 1055 is subjected to force and buffers, it buffers and protects the buffer plate 1052. When the buffer plate 1052 is buffered, it drives the control slide rod 1056 to slide inside the control hollow plate 1057, so that the buffer plate 1052 can stably buffer and protect. At the same time, when it is impacted on the side, it contacts the rubber buffer plate 1054 for direct buffer protection. This facilitates the buffer protection effect of the inspection and maintenance vehicle body 100 on the inspection display 105 when inspecting and maintaining the high-speed rail track plate.

[0035] Finally, when the inspection and maintenance vehicle body 100 moves to the concrete slab where the track is installed and requires pressure resistance inspection and maintenance, during the inspection, the handwheel 1018 is used to rotate the double-acting screw 1015. As the double-acting screw 1015 rotates, it causes the two moving seats 1016 at both ends of the double-acting screw 1015 to move towards each other. This movement of the moving seats 1016 causes the anti-slip reinforcing plate 1011 to move inside the mounting groove 1012. The movement of the anti-slip reinforcing plate 1011 causes the limiting slider 1014 to slide within the limiting groove 1013. The two sets of anti-slip reinforcement plates 1011 are moved towards each other and reinforced and clamped to the side of the track. The locking bolts 1017 are rotated again and embedded into the internal threaded holes 1019 for internal fixation. This makes the inspection and maintenance vehicle body 100 reinforced and installed at the inspection point for inspection and maintenance. It is also less likely to cause instability when the pressure-resistant inspection column 108 is moved down to detect the force. The reinforced inspection and maintenance results are more accurate and safer to operate. This improves the reinforcement and accuracy of the inspection and maintenance vehicle body 100 when performing pressure-resistant inspection and maintenance on the concrete slab installed on the high-speed rail track.
