[0033] The utility model will be further described below with reference to the drawings.

[0034] Reference Figure 1 and Figure 2As shown, the mounting structure 100 for the train 210 bottom provided by the utility model, it includes: the bottom support 110, the positioning seat 120, the safety rope 130 and the ring buckle 140. Among them, the positioning seat 120 is installed at the bottom of the bottom support 110, the safety rope 130 is installed at the bottom support 110, and the ring buckle 140 is installed at the bottom of the safety rope 130.

[0035] In use, the bottom support 110 is fixed at the bottom of the train 210, and the detection equipment to be used is matched with the positioning structure 121 on the positioning seat 120, the positioning of the detection device installation position is realized, and then the fastener is connected with the mounting hole 122, so that the detection device is installed on the positioning seat 120.

[0036] In the application, the mounting structure 100 is used in pairs, one detection device is installed on each mounting structure 100, and the two mounting structures 100 in a pair of mounting structures 100 are symmetrical along the central axis of the train 210, so that the two detection devices installed on the pair of mounting structures 100 are symmetrical.

[0037] The fastener here is generally a bolt, which is connected with the internal thread of the mounting hole 122 through the fastener passing through the detection device, so as to realize the detachable connection of the fastener and the mounting hole 122. In other implementation modes, when the fastener is a plug, the mounting hole 122 can be provided as a corresponding socket structure to realize the detachable connection of the fastener and the mounting hole 122.

[0038] Since the positioning structure 121 is arranged on the positioning seat 120, the positioning of the detection device can be realized, the installation precision is improved, so that the detection device installed on the mounting structure 100 remains in the same position, and the calibration result of the detection device initially installed on the mounting structure 100 can be reused in the detection device installed later, avoiding the problem of repeated calibration due to low installation precision.

[0039] Referring to Figure 3 As shown, in some implementation modes, the positioning structure 121 is a spherical groove structure, which can be suitable for accurate positioning of the detection device with a spherical head structure, and in other implementation modes, the positioning structure 121 can also be a positioning hole structure or a positioning groove structure, so as to accurately position the detection device provided with a positioning protrusion. It can be understood that when the detection device is provided with a positioning recess, the positioning structure 121 can also be provided as a positioning protrusion, which can realize accurate positioning of the detection device when the positioning protrusion is inserted into the positioning recess on the detection device.

[0040] The spherical groove of the positioning structure 121 is communicated with the mounting hole 122, so that the bolt can be inserted into the mounting hole after the positioning ball head of the detection device is inserted into the spherical groove of the positioning structure 121, thereby achieving the fixation and positioning of the detection device.

[0041] After the detection device is fixed to the positioning seat 120 by the fastener, the loop buckle 140 can be connected to the detection device, and the detection device can be hung by the loop buckle 140 and the safety rope 130 after the detection device is separated from the positioning seat 120. Therefore, it is not necessary to hold the detection device during the process of removing the fastener from below the train 210, and the difficulty of removing the detection device from below the train 210 is reduced.

[0042] The structure of the loop buckle 140 is shown in Figure 4 The notch ring body 141 is connected with the stop block 142 through the rotating shaft 143 at the notch. A torsion spring is further arranged between the stop block 142 and the notch ring body 141 to keep the stop block 142 in the position of filling the notch of the notch ring body 141. When it is necessary to open the loop buckle 140, the stop block 142 only needs to be pressed to drive the stop block 142 to rotate relative to the rotating shaft 143, so as to connect or separate the loop buckle 140 and the detection device. The connection and separation are relatively simple.

[0043] In order to meet the connection of the loop buckle 140 and the detection device, a plurality of through holes can be arranged on the detection device to facilitate the notch ring body 141 of the loop buckle 140 to pass through, or a plurality of hanging rings can be connected to the detection device, and the connection of the loop buckle 140 and the hanging ring can achieve the connection of the loop buckle 140 and the detection device.

[0044] Referring to Figure 1 and Figure 2 The vehicle bottom support 110 includes a first reinforcing component 111, a second reinforcing component 112 and a connecting bottom plate 113. The first reinforcing component 111 extends along the driving direction of the train 210, the second reinforcing component 112 extends along the width direction of the train 210, the first reinforcing component 111 and the second reinforcing component 112 are connected to the top surface of the connecting bottom plate 113, and the positioning seat 120 is fixed to the bottom of the connecting bottom plate 113.

[0045] Since the direction of the traction force during the driving of the train 210 is along the driving direction of the train 210, the train 210 will be deformed along the driving direction of the train 210 during the driving. The first reinforcing component 111 extending along the driving direction of the train 210 can improve the strength of the vehicle bottom support 110 in the driving direction of the train 210, thereby reducing the deformation of the vehicle bottom support 110 in the driving direction of the train 210 and avoiding damage to the detection device due to the deformation along the driving direction of the train 210.

[0046] When the train 210 turns, it is also subjected to lateral forces on the track 220, which can cause the train 210 to deform along the width of the train 210. The second reinforcement assembly 112 extending along the width of the train 210 can reduce deformation of the detection device along the width of the train 210.

[0047] That is to say, due to the provision of the first reinforcement component 111 and the second reinforcement component 112, the strength of the mounting structure 100 in the direction of travel of the train 210 and the width direction of the train 210 can be improved, thereby reducing the deformation of the detection device and better protecting the detection device.

[0048] See also Figure 1 、 Figure 2 and 5 As shown, the first reinforcement assembly 111 includes two parallel first reinforcement vertical plates 1111, and the second reinforcement assembly 112 includes two parallel second reinforcement vertical plates 1121. The two second reinforcement vertical plates 1121 are connected to the same first reinforcement vertical plate 1111, and the two second reinforcement vertical plates 1121 are both arranged on the side of the first reinforcement assembly 111 close to the central axis of the train 210.

[0049] By arranging the two second reinforcing vertical plates 1121 on the same side of the first reinforcing assembly 111, the length of the undercarriage support 110 in the width direction of the train 210 is reduced compared to arranging the two reinforcing vertical plates on opposite sides of the first reinforcing assembly 111, thereby reducing the difficulty of arranging the undercarriage support 110.

[0050] Moreover, directly connecting the second reinforcing vertical plate 1121 to the first reinforcing vertical plate 1111 can realize force transmission between the first reinforcing assembly 111 and the second reinforcing assembly 112, which improves the deformation resistance of the vehicle bottom bracket 110 compared to setting the first reinforcing assembly 111 and the second reinforcing assembly 112 at intervals.

[0051] In some implementations, the two first reinforcing risers 1111 are symmetrical along a first straight line, and the two second reinforcing risers 1121 are also symmetrical along the first straight line, wherein the first straight line extends along the width direction of the train 210 .

[0052] In other words, the undercarriage support 110 generally has a T-shaped structure. When the undercarriage support 110 is subjected to a force along the width of the train 210, the two second reinforcing risers 1121 simultaneously transmit the force to the first reinforcing assembly 111. The resultant force of these two forces is generally along the first straight line. The first reinforcing assembly 111 is symmetrical along the first straight line, meaning that the resultant force of the second reinforcing assembly 112 acts on the central region of the first reinforcing assembly 111. Compared to forces acting on both sides of the first reinforcing assembly 111, the force in the central region can be transferred to the front and rear sides, reducing the risk of deformation.

[0053] Referring to Figure 1 and Figure 5 As shown in the figures, the first reinforcing assembly 111 further comprises a first support plate 1112, which is arranged between the two first reinforcing vertical plates 1111 to connect the two first reinforcing vertical plates 1111.

[0054] The force transmission between the two first reinforcing vertical plates 1111 can be achieved through the first support plate 1112, thereby reducing the risk of deformation.

[0055] Referring to Figure 1 and Figure 5 In some implementations, at least two first support plates 1112 are arranged between the two adjacent first reinforcing vertical plates 1111, and the extension direction of the first support plates 1112 is the same as the extension direction of the second reinforcing assembly 112.

[0056] Compared with a single first support plate 1112, the arrangement of two first support plates 1112 can better maintain the change of the spacing between the two first reinforcing vertical plates 1111, and the extension direction of the first support plates 1112 being the same as the extension direction of the second reinforcing assembly 112 can extend the force transmission path in the width direction of the train 210 through the first support plates 1112, thereby improving the strength of the underframe 110 in the width direction of the train 210 and avoiding deformation of the underframe 110 in the width direction of the train 210.

[0057] Referring to Figure 1 and Figure 5 As shown in the figures, the second reinforcing assembly 112 comprises a second support plate 1122, which is arranged between the two second reinforcing vertical plates 1121 to connect the two second reinforcing vertical plates 1121, and the second support plate 1122 is arranged in parallel and spaced apart from the first reinforcing vertical plate 1111. The change of the gap between the two second reinforcing vertical plates 1121 can be avoided through the second support plate 1122, thereby improving the anti-deformation capability of the underframe 110. The second support plate 1122 is arranged in parallel and spaced apart from the first reinforcing vertical plate 1111, which can make the second support plate 1122, the first reinforcing vertical plate 1111, and the two second reinforcing vertical plates 1121 connected to form a frame structure, thereby improving the strength of the underframe 110.

[0058] Referring to Figure 6 and Figure 7As shown, at least three positioning seats 120 are installed on the vehicle bottom bracket 110, and each positioning seat 120 corresponds to a fastener. A part of the positioning seats 120 is installed in the first area 1131 connected to the base plate 113, and the other part of the positioning seats 120 is installed in the second area 1132 connected to the base plate 113. The first area 1131 is located between the two first reinforcing vertical plates 1111, and the second area 1132 is located between the two second reinforcing vertical plates 1121.

[0059] By setting some positioning seats 120 in the first area 1131 and other positioning seats 120 in the second area 1132, compared to setting the positioning seats 120 on the side of the first reinforcing vertical plate 1111 away from the second reinforcing component 112, or setting the positioning seats 120 in the angle area formed by the first reinforcing component 111 and the second reinforcing component 112, the size of the connecting base plate 113 can be reduced, thereby reducing the material cost of the mounting structure 100.

[0060] See also Figure 1 and Figure 5 As shown, in some implementations, weight-reducing holes 11111 are provided on both the first reinforcing riser 1111 and the second reinforcing riser 1121, which can reduce the mass of the first reinforcing riser 1111 and the second reinforcing riser 1121, thereby reducing the material cost of the mounting structure 100. It is understood that weight-reducing holes 11111 may be provided only on the first reinforcing riser 1111, or only on the second reinforcing riser 1121.

[0061] See also Figure 1 and Figure 6 As shown, in some implementations, the undercarriage support 110 is mounted with four safety ropes 130, and the projections of the fixing points of the four safety ropes 130 on a horizontal plane can be connected to form a quadrilateral. Increasing the number of safety ropes 130 allows for the lifting of heavier detection devices. By controlling the arrangement of the fixing points of the four safety ropes 130, it is possible to avoid multiple fixing points being arranged on the same straight line, thereby preventing the detection device from tipping over.

In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist.
