Description

Technical Field

[0001] This application relates to the field of railway inspection technology, and in particular to an installation mechanism for the front-end inspection equipment of a railway inspection vehicle. Background Technology

[0002] The four-person railway inspection vehicle is commonly used in daily railway track inspections. It is mainly used for tasks such as detecting cracks on the track surface, checking the condition of sleepers, and measuring catenary parameters. Various inspection equipment needs to be fixedly installed at its front end, such as a 4K resolution high-definition track camera, an infrared thermal imager with a measurement accuracy of ±0.1℃, a track gauge dynamic sensor or lidar with a sampling frequency of 1000Hz, etc. The stable installation of these devices directly determines the accuracy and reliability of the inspection data. Currently, the installation of front-end inspection equipment for four-person railway trolleys generally adopts the traditional bolt fastening method, which has three major problems: The disassembly and assembly efficiency is extremely low: the equipment is fixed to the front mounting base of the trolley by 6-8 M10 bolts. Each time the equipment is replaced or maintained, a torque wrench must be used to remove the bolts one by one. The average time for a single disassembly and assembly is 35-50 minutes, which seriously restricts the inspection progress. High operational threshold and poor safety: The disassembly and assembly process requires the cooperation of 2 people (1 person to fix the equipment and 1 person to operate the wrench), and the bolts are prone to jamming due to rust, requiring the use of a hammer to assist in disassembly, which poses a risk of equipment slipping and being damaged; In addition, while some simple quick-release solutions (such as snap-on designs) can shorten the disassembly and assembly time, their load-bearing capacity is insufficient (rated load ≤ 3kg), making them unsuitable for infrared thermal imagers or lidar devices weighing more than 5kg. Furthermore, the snaps are prone to falling off under vibration, posing a high risk of equipment falling.

[0003] While industry solutions exist to address these issues, significant shortcomings remain, failing to meet actual inspection needs. For instance, quick-release bolts replace traditional bolts, but in practice, their strength is reduced by 20%. When equipment weight exceeds 6kg, bolts are prone to deformation, posing a safety hazard. Another example is using strong magnetic chucks (with suction force ≥800N) to attach the equipment to the metal base at the front of the trolley. However, strong magnets interfere with internal electronic components (such as Hall elements in sensors and integrated circuits in data acquisition modules), leading to distorted detection data (e.g., increased track gauge measurement error by 5-8mm). Furthermore, in humid or low-temperature environments (≤-10℃), the suction force decreases by 30%-50%, significantly increasing the risk of equipment detachment. This approach is only suitable for light-load (≤4kg) and low-precision inspection scenarios. Furthermore, none of the existing solutions have designed a specific anti-vibration structure for the vibration characteristics of the trolley, and the accuracy and stability of the equipment under vibration environment have not been fundamentally resolved. The equipment offset of different solutions is still generally higher than 1mm, which cannot meet the requirements of high-precision detection. Utility Model Content

[0004] The purpose of this application is to address the problems of low installation efficiency, poor convenience, insufficient load-bearing capacity, and poor stability of the front-end inspection equipment of railway inspection vehicles in the prior art. Therefore, this application provides an installation mechanism for the front-end inspection equipment of railway inspection vehicles. By integrating multiple inspection devices into the housing, and by using locking blocks on the housing and locking seats on the mounting base to initially achieve a detachable connection between the housing and the mounting base, and then using locking components to achieve secondary fixation between the two, the installation efficiency, convenience, load-bearing capacity, and stability of the front-end inspection equipment of railway inspection vehicles are improved.

A locking member is provided on the side of the locking seat, and the locking member is used to insert the locking block into the locking seat along a second direction perpendicular to the first direction in the inserted state, thereby fixing the housing and the mounting seat in the first direction.

This allows multiple inspection devices to be installed at the front of the railway inspection vehicle, which can be operated by a single person without the need for disassembly tools, thereby improving installation efficiency and convenience. Furthermore, the locking block and the locking seat have a large contact area and high strength, which improves the load-bearing capacity of the mounting base on the housing, i.e., the inspection device, enhances the adaptability of this installation mechanism to various inspection devices, and improves installation safety. At the same time, the multi-directional cooperation and limiting of the locking block and the locking seat, as well as the locking component that can be locked in the second direction, improves installation stability and greatly reduces the displacement of the inspection device in a vibration environment.

[0007] In some embodiments, the first direction is the vertical direction.

[0010] In some embodiments, wedge-shaped grooves are provided on opposite sides of the locking block, and one end of the wedge-shaped groove extends through the bottom of the locking block; the locking seat is provided with a matching protrusion corresponding to the wedge-shaped groove.

[0011] In some embodiments, the locking seat has a base plate, and the locking block is supported by the base plate in the inserted state.

[0012] In some embodiments, the mounting base includes a back plate, a partition, and a reinforcing plate, wherein the partition is disposed on the back plate and divides the back plate into a first mounting area and a second mounting area along the second direction; The locking seat is provided in the first installation area; One side of the back plate in the second installation area is used to fix it to the mounting base at the front end of the railway inspection vehicle, and the other side is provided with the reinforcing plate. The reinforcing plate extends along the second direction, and the reinforcing plate, the back plate, and the partition plate are connected to form a triangular structure.

[0013] In some embodiments, the back plate of the second mounting area is provided with a waist-shaped hole, and the fixed position of the mounting base at the front end of the railway inspection vehicle is adjusted through the waist-shaped hole, so that the inspection equipment installed on the locking seat is in the detection position.

[0014] In some embodiments, the plurality of inspection devices are three line scanning cameras that are respectively arranged on both sides and the top surface of the track. The shape of the housing is adapted to the layout of the three line scanning cameras, and the housing is provided with ventilation holes. The top of the housing is provided with a handle.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating the usage status of this application.

[0022] The railway inspection vehicle 1 can be a four-person railway trolley used for double-rail flaw detection, etc. Inspection equipment is usually installed at the front of the inspection vehicle to realize double-rail detection, such as a line scan camera, which scans the track segment by segment by following the vehicle to obtain high-resolution image data for detection.

[0023] Inspection equipment needs to be disassembled regularly for easy maintenance. However, the current inspection equipment is usually fixed to the mounting base 2 at the front of the inspection vehicle with traditional bolts, which results in low disassembly and assembly efficiency and inconvenience in operation. Other installation methods, such as clips and magnetic attraction, have problems such as insufficient load-bearing capacity and poor installation stability.

[0024] Therefore, this application provides an installation mechanism for the front-end inspection equipment of a railway inspection vehicle 1, including a housing 10 and a mounting base 20. Multiple inspection devices are integrated through the housing 10, and the locking block 30 on the housing 10 and the locking seat 40 on the mounting base 20 cooperate to initially achieve a detachable connection between the housing 10 and the mounting base 20. Then, the locking member 50 achieves secondary fixation between the two, which improves the installation efficiency, convenience, load-bearing capacity and stability of the front-end inspection equipment of the railway inspection vehicle 1.

[0025] Please see Figure 2-4 , Figure 2 This is a schematic diagram of the structure of this application; Figure 3 This is a schematic diagram of the locking block 30 in this application; Figure 4 This is a schematic diagram of the locking seat 40 in this application.

[0026] The housing 10 is used to accommodate and install multiple inspection devices, and a locking block 30 is provided on one side of the housing 10.

[0027] Mounting seat 20 is used to fix to mounting base 2 at the front end of railway inspection vehicle 1, and mounting seat 20 is provided with a matching locking seat 40 corresponding to locking block 30.

[0028] The housing 10 is inserted into and removed from the locking seat 40 along the first direction via the locking block 30. In the inserted state, the circumference and bottom surface of the locking block 30 are confined within the locking seat 40, enabling a detachable connection between the housing 10 and the mounting base 20. This allows multiple inspection devices to be installed as a whole at the front of the railway inspection vehicle 1 or disassembled as a whole, which can be operated by a single person without the need for disassembly tools, thus improving installation efficiency and convenience. Furthermore, the large contact area and high strength of the locking block 30 and the locking seat 40 enhance the load-bearing capacity of the mounting base 20 on the housing 10, i.e., the inspection equipment, improving the adaptability of this installation mechanism to various inspection devices and enhancing installation safety.

[0029] A locking element 50 is provided on the side of the locking seat 40. The locking element 50 is used to insert the locking block 30 into the locking seat 40 in a second direction perpendicular to the first direction when the device is inserted, thereby fixing the housing 10 and the mounting base 20 in the first direction. That is, the locking block 30 and the locking seat 40 first cooperate and limit the device in multiple directions, including the circumferential and bottom surfaces, and then the locking element 50, which can be locked in the second direction, achieves secondary fixation. This improves the installation stability and greatly reduces the offset of the inspection equipment in a vibration environment, thereby meeting the requirements of high-precision detection.

[0030] Preferably, both the locking block 30 and the locking seat 40 are made of 6061 aluminum alloy and have undergone hard anodizing treatment to ensure that the hardness meets the requirements.

[0031] Experiments show that this installation mechanism allows for a single disassembly and assembly time of ≤3 minutes for the inspection equipment, and requires no special tools, allowing for operation by a single person. This installation mechanism also ensures high precision and stability of the inspection equipment, with a displacement of ≤0.3mm under vibration after installation, meeting railway inspection standards. Furthermore, this installation mechanism offers high load-bearing safety, with a rated load of ≥8kg, is compatible with all mainstream inspection equipment, and has a reliable structure to prevent detachment.

[0032] In one embodiment, the first direction is the vertical direction, which is perpendicular to the top surface of the track in the use state, so that the locking block 30 can be vertically inserted and removed from the locking seat 40, that is, the operator operates vertically, which further improves the ease of installation of the housing 10 and the mounting base 20, and utilizes the self-weight of the housing 10 and the multiple inspection devices inside it to further improve the installation stability of the housing 10 and the mounting base 20.

[0033] In other alternative implementations, the first direction is horizontal, which is parallel to the top surface of the track in the use state, so that the locking block 30 can be horizontally inserted and removed from the locking seat 40 from the side, that is, the operator operates from the side, and this operation method is also convenient.

[0034] In one embodiment, the locking element 50 is a locking plunger, which is convenient to operate and provides reliable locking. A locking plunger is a commonly used mechanical part for positioning and fixing workpieces. Its built-in spring allows the locking pin at the front end to easily sink into the body when subjected to external load. Once the load is released, the spring force causes the locking pin to quickly return to its original position, ensuring efficient plunger reset. Therefore, the locking block 30 is provided with a positioning hole 31 corresponding to the locking pin of the locking plunger for easy locking. Furthermore, the locking block 30 is provided with a mounting hole 41 corresponding to the positioning hole 31 for mounting the locking plunger.

[0035] Preferably, the locking plunger is a knob plunger, meaning that the movement of its pin can be controlled by operating a knob. Alternatively, the locking plunger is a press-to-unlock plunger, meaning that the movement of its pin can be controlled by operating a press mechanism.

[0036] Please see again Figure 3-4 In one embodiment, wedge-shaped grooves 32 are provided on opposite sides of the locking block 30, and one end of the wedge-shaped grooves 32 penetrates the bottom of the locking block 30. The locking seat 40 is provided with a matching protrusion 42 corresponding to the wedge-shaped grooves 32, so that the two can not only be inserted and removed, but also the contact area is further increased, which further enhances the connection strength. At the same time, the front, back, left and right limiting and fixing effects are better, which further enhances the stability of the overall structure and improves the anti-disengagement effect of the two during the inspection process.

[0037] Preferably, the cross section of the wedge groove 32 perpendicular to the first direction is an isosceles trapezoid, and its large end is an open end, thereby further improving the ease of insertion and removal.

[0038] In one embodiment, the end face of the wedge groove 32 penetrating the locking block 30 is set as an inclined surface to guide the wedge groove 32 to the protrusion 42, thereby further improving the ease of installation.

[0039] Please see again Figure 2In one embodiment, the locking seat 40 has a base plate 43, which supports the locking block 30 when it is inserted. Generally, the bottom surface area of ​​the locking block 30 is larger than the contact area between the top of its wedge groove 32 and the top of the protrusion 42 of the locking seat 40. Therefore, by having the base plate 43 contact the bottom surface of the locking block 30 and provide support, the load-bearing capacity and the stability of the locking block 30 installed in the locking seat 40 can be further improved.

[0040] Preferably, the bottom surface area of ​​the locking block 30 is 3-4 times the cross-sectional area of ​​the wedge groove 32 perpendicular to the first direction, so as to take into account both the strength of the locking block 30 itself and the connection strength between it and the locking seat 40 through the wedge groove 32.

[0041] Please see Figure 5 , Figure 5 This is a schematic diagram of the mounting base 20 in this application.

[0042] It should be noted that, in order to inspect the rail surface, the front-end inspection equipment needs to be installed on the side of the inspection vehicle body, in the same direction as the traveling wheels. This makes the part of the mounting housing 10 of the mounting base 20 suspended in the air. Moreover, due to the large weight of the mounting housing 10 and the inspection equipment inside it, the strength requirements of the mounting base 20 and the installation part of the inspection vehicle are further increased.

[0043] Therefore, in one embodiment, the mounting base 20 includes a back plate 21, a partition 22, and a reinforcing plate 23. The partition 22 is disposed on the back plate 21 and divides the back plate 21 into a first mounting area 24 and a second mounting area 25 along a second direction.

[0044] The first installation area 24 is provided with a locking seat 40. Preferably, one side of the locking seat 40 is attached to the partition 22 for easy positioning and installation, and improves installation reliability.

[0045] One side of the back plate 21 of the second installation area 25 is used to fix it to the mounting base 2 at the front end of the railway inspection vehicle 1, and the other side is provided with a reinforcing plate 23. The reinforcing plate 23 extends along the second direction, and the reinforcing plate 23 is connected with the back plate 21 and the partition plate 22 to form a triangular structure, thereby strengthening the strength of the mounting base 20 and improving its load-bearing capacity.

[0046] In one embodiment, the back plate 21 of the second installation area 25 is provided with a waist-shaped hole 251, and the fixed position of the mounting base 2 at the front end of the railway inspection vehicle 1 is adjusted through the waist-shaped hole 251, so that the inspection equipment installed on the locking seat 40 is in the detection position, thereby further improving the ease of installation.

[0047] In one embodiment, the multiple inspection devices consist of three line-scan cameras (the layout is the same as in the prior art) installed on each of the two sides and the top surface of the track, and the shape of the housing 10 is adapted to the layout of the three line-scan cameras. The weight range of the three line-scan cameras is more compatible with the load-bearing capacity of this mounting mechanism, thereby further ensuring installation safety and stability.

[0048] Preferably, the housing 10 is provided with vents to facilitate heat dissipation of the internal inspection equipment. Furthermore, the top of the housing 10 is provided with a handle 11 to further facilitate disassembly and assembly operations.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
