[0002] Now the operating mileage of high-speed railways is getting longer and longer, which also provides a lot of convenience for users. With a large number of new high-speed railway lines intensively opened and operated, a large number of new technologies and equipment put into use, and the passenger volume continuing to hit new highs, it is necessary to always put high-speed railway safety supervision in the first place to ensure the safety of passengers. Safe operation is the life of high-speed railways, and the detection of uneven settlement of high-speed railway track surfaces is an important guarantee for the safe operation of high-speed railways. Therefore, dynamic, fast and accurate detection of uneven settlement of high-speed railway track surfaces is a major demand.

[0003] The measurement of railway tracks needs to be measured repeatedly and the same area needs to be measured back and forth. Therefore, after arriving at the designated area, the measuring frame needs to be turned 180 degrees. The usual practice is to lift and flip it by multiple people. However, due to the large number of precision instruments on the frame, the equipment will shake during transportation, resulting in errors in the measurement data. In response to the above problems, the following solutions are proposed. Summary of the invention

[0006] A power mechanism, the power mechanism is located at the inner wall of the support mechanism and is used to provide a rotation support position for the frame mechanism; and

[0007] The safety mechanism is located at the bottom of the power mechanism. Through the contraction of the power mechanism, the contraction speed of the safety mechanism is controlled to ensure the orderly contraction of the equipment;

[0008] The frame mechanism detects data on the rails through the detection instrument on the top. When turning is required, the power mechanism contacts the inner wall of the rails, so that the support mechanism is separated from the power mechanism. Finally, the turning of the equipment is completed through manual rotation.

[0009] Preferably, a frame is fixedly arranged on the top of the frame mechanism, and the frame mechanism comprises:

[0010] An analysis component, the bottom of which is fixedly arranged on the top of the frame and is used for collecting external railway information;

[0011] A driving assembly, the driving assembly and the side wall of the frame mechanism are rotatably arranged to drive the frame mechanism to move on the rails;

[0012] The driving component drives the analyzing component to move along the outer wall of the rail through the frame to collect data information of the outer wall of the rail.

[0013] Preferably, the supporting mechanism comprises:

[0014] A separation component, which is slidably arranged on the inner wall of the frame through a sliding member and is used for sliding separation from the frame;

[0015] The sliding member includes a sliding rod slidably connected to the inner wall of the frame, and the separation assembly also includes a mounting groove opened on the inner wall of the sliding rod;

[0016] A support assembly, the support assembly is fixedly arranged on the inner wall of the frame through a support member;

[0017] The support member includes a hydraulic telescopic rod 1 fixedly connected to the top of the sliding rod, and one end of the hydraulic telescopic rod 1 away from the sliding rod is rotatably connected to the inner wall of the frame, and is used to provide a rotation support position for the frame after the frame is separated;

[0018] When the equipment is running, after the separation assembly is separated from the frame, the staff can push the equipment to make the equipment rotate around the support assembly, and ensure that after the support assembly completes the turning, it can be placed stably on the top of the rail again.

[0019] Preferably, the power mechanism comprises:

[0020] An extension component, which is fixedly arranged on the inner wall of the separation component through a driving member and is used to provide power during separation;

[0021] The driving member comprises a motor fixedly connected to the inner wall of the mounting groove, the output shaft of the motor is fixedly connected to a gear, and the inner wall of the mounting groove is slidably connected to an L-shaped gear rod;

[0022] A control component is slidably disposed on the inner wall of the separation component through a limiting member, and is used to provide a clamping force during separation to limit the movement of the separation component;

[0023] The limiting member comprises a sliding block 2 which is slidably connected to the inner wall of the installation groove, and a hydraulic box 1 is fixedly connected to the bottom of the sliding block 2;

[0024] The contact assembly is fixed to the bottom of the control assembly through a hydraulic component and is used to contact the inner wall of the rail, changing the contact mode and converting the friction contact of the contact plate into a buckle design. The support mechanism and the power mechanism will generate a downward thrust during operation, and the buckle design increases the contact area; and

[0025] The hydraulic component includes a contact box fixedly connected to the bottom of the sliding column, and a plurality of sliding plates are fixedly connected to the inner wall of the contact box;

[0026] Before separation, the extension component drives the contact component to contact the inner wall of the rail through the control component, so that the power mechanism, the support mechanism and the rail are clamped and fixed, providing a turning support point for separation.

[0027] Preferably, the insurance institutions include:

[0028] A limit assembly, which is fixedly arranged on the outer wall of the control assembly through a limiting member, and is used to limit the speed of the control assembly when it is reset;

[0029] The limiting member includes a hydraulic telescopic rod three which is connected through both sides of a hydraulic box one, and a sliding bracket one is fixedly connected to the bottom of the sliding block two;

[0030] An adjusting component, wherein the hindering member of the adjusting component is fixedly arranged on the outer wall of the limiting component, and is used to drive the moving speed of the limiting component;

[0031] The obstruction member includes an arc-shaped toothed rod fixedly connected to the bottom of the sliding rod;

[0032] Among them, after completing the direction change, the extension component drives each component to reset, and the limit component and the adjustment component will control the reset speed and sequence of the power mechanism. The buckle design can avoid the situation where the friction force is insufficient in the early stage, and the support mechanism and the power mechanism will generate downward thrust, resulting in the power mechanism being unable to provide sufficient support force for the equipment.

[0033] Preferably, the analysis component includes a data analyzer fixedly connected to the top of the frame, and the top of the frame is rotatably connected to an operating rod. Before use, after ensuring the safety of the application environment, the device is placed on the rails, and then the operation detection of the device is controlled by the operating rod;

[0034] The two sides of the driving assembly are fixedly connected with fixing frames, and the side walls of the two fixing frames are rotatably connected with three driving wheels;

[0035] When in use, the staff can force the driving wheel to rotate through the operating lever, so that the driving wheel drives the frame and the data analyzer to move along the outer wall of the rail through the fixed frame.

[0036] Preferably, the separation assembly comprises an inclined plate fixedly connected to the inner wall of the mounting groove, and the inclined plate, when in use, forces the control assembly to drive the contact assembly to contact the inner wall of the external rail;

[0037] The support assembly includes a transmission pipe connected to a side wall of the hydraulic telescopic rod. When the hydraulic telescopic rod is extended, the frame is forced to slide upward along the inner wall of the sliding rod, so that the sliding rod slides away from the inner wall of the frame.

[0038] The transmission pipe transmits hydraulic oil to the hydraulic telescopic rod 1, so that the hydraulic telescopic rod 1 is extended. The extended hydraulic telescopic rod 1 separates the sliding rod from the frame, and the hydraulic telescopic rod 1 provides a rotation support point after separation.

[0039] Preferably, the extension assembly includes a hydraulic pipe fixedly connected to the side wall of the L-shaped gear rod, a sliding block 1 is slidably connected to the inner wall of the hydraulic pipe, and the outer wall of the L-shaped gear rod is meshedly connected with the outer wall of the gear. During operation, the sliding block 1 will slide along the inner wall of the hydraulic pipe;

[0040] The extension component includes a support rod fixedly connected to one side wall of the sliding block. During operation, the motor drives the L-shaped gear rod to slide and extend along the inner wall of the installation groove through the gear. When the contact box contacts the side wall of the rail, the support rod is restricted and will no longer move. When the L-shaped gear rod continues to move outward, the sliding block 1 will move along the inner wall of the hydraulic pipe in the direction of the gear, and the hydraulic oil inside the hydraulic pipe will be transmitted to the hydraulic telescopic rod 1 through the transmission pipe, so that the hydraulic telescopic rod 1 will be extended. The extended hydraulic telescopic rod 1 will force the frame and related components to slide upward along the outer wall of the sliding rod, and finally the sliding rod and the frame will be completely separated. At this time, the staff can force the frame mechanism, the support mechanism and the power mechanism to rotate around the hydraulic telescopic rod 1 by pushing one end of the frame. Through the application of the above components, when the equipment needs to turn, the support mechanism and the power mechanism can provide a support point, thereby reducing the impact of external vibration force on the instrument when the equipment turns.

[0041] The control assembly includes a hydraulic telescopic rod 2 which is connected through a side wall of the hydraulic box, and a fixed plate is fixedly connected to one end of the hydraulic telescopic rod 2 which is away from the hydraulic box 1;

[0042] The control component includes a sliding column slidably connected to the inner wall of the sliding block 2, the top of the sliding column is rotatably connected to a rolling column, and the end of the support rod away from the sliding block 1 is fixedly connected to the side wall of the fixed plate. When the equipment reaches the edge of the area, the staff turns on the power of the motor, and the motor drives the two L-shaped gear rods to slide to both sides along the inner wall of the installation groove through the gears. The outward-moving L-shaped gear rods will drive the hydraulic pipe, the sliding block 1 and the support rod to move outward synchronously, and the support rod drives the hydraulic box to move together through the fixed plate and the hydraulic telescopic rod 2. In this process, the hydraulic box 1 drives the sliding block 2 to slide along the inclined surface of the inclined plate, so that the sliding column slides downward along the inner wall of the sliding block 2, and at this time, the side wall of the contact box contacts the inner wall of the rail, and the contact boxes at the left and right ends contact the inner wall of the rail to form a clamping force, which will move the sliding rod;

[0043] When the extension component extends outward, the control component is driven to extend outward synchronously. During this process, the rolling column will contact the inclined surface of the inclined plate and force the sliding column to slide downward along the inner wall of the sliding block 2.

[0044] Preferably, the contact assembly includes a contact plate slidably connected between a plurality of sliding plates, and flow ports are provided at the side walls of the plurality of sliding plates. The characteristic of the contact box being in outward contact with the outer wall of the rail is utilized, and a contact assembly is provided inside the device. When the contact box contacts the outer wall of the rail, the side wall of the contact plate will first contact the inner wall of the rail. At this time, the contact surface of the rail will force the contact plate to slide along the gap between the sliding plates, and the hydraulic oil inside the contact box will be squeezed to flow through the flow ports. Moreover, as the pressures on the various contact plates are different, the degrees of inward sliding of the contact plates are also different, so that the contact plates are finally formed as follows Fig.11 In the state of medium G, through the application of the above components, it is ensured that the contact plate can adapt to the undulating surface of the inner wall of the rail when the equipment is extruding, thereby ensuring the stability of the contact surface of the equipment.

[0045] When the sliding column moves outward, the side wall of the contact plate is driven to contact the inner wall of the rail, so that the contact assembly changes from extrusion contact to snap-on contact.

[0046] Preferably, the limit assembly includes a U-shaped sliding frame fixedly connected to the end of the hydraulic telescopic rod three away from the hydraulic box one, the outer wall of the U-shaped sliding frame is slidably connected to the inner wall of the sliding bracket one, and the inner wall of the U-shaped sliding frame is provided with a sliding groove one, and the hydraulic telescopic rod three is driven to shrink synchronously by the contraction of the hydraulic telescopic rod two, and the contact plate is deformed after contacting the rail, and when the contact plate contacts the outer wall of the rail, the contact plate at the top will extend to the top of the rail to form a buckled state, such as Fig.11In the middle F state, the friction contact of the contact plate is converted into a snap-on design, and the support mechanism and the power mechanism will generate a downward thrust during operation. The snap-on design increases the contact area while avoiding the situation where the friction between the contact plate and the rail is insufficient in the early stage. The support mechanism and the power mechanism generate a downward thrust, resulting in the power mechanism being unable to provide sufficient support for the equipment.

[0047] Preferably, the adjustment component includes a sliding block slidably connected to the inner wall of the slide groove, the side wall of the sliding block is provided with an arc surface, the side wall of the sliding block is fixedly connected with a spring, and the end of the spring away from the sliding block is fixedly connected to the inner wall of the U-shaped sliding frame. After the device completes the steering, the motor will drive the various components to reset. A safety mechanism is provided inside the device. When the motor drives the L-shaped gear rod to reset, the L-shaped gear rod will move in the direction of the motor. In this process, since the plane of the sliding block contacts the plane of the arc-shaped gear rod, as shown in FIG. Fig.10 As shown, the movement of the adjustment component, the limit component and the sliding block 2 is limited, and as the distance between the sliding block 2 and the L-shaped gear rod increases, the sliding block 1 will slide along the inner wall of the hydraulic pipe, so that the hydraulic pipe extracts the solution inside the hydraulic telescopic rod 1 through the transmission pipe, forcing the hydraulic telescopic rod 1 to contract, and the contraction of the hydraulic telescopic rod 1 will drive the frame and the driving component to reset synchronously, so that the driving wheel contacts the outer wall of the rail;

[0048] When the U-shaped sliding frame drives the sliding block to move outward, the sliding block will slide along the outer wall of the arc-shaped toothed rod to limit the resetting of the adjusting component. After the sliding block 1 moves outward to the outermost position, the force of the contraction of the contact component will be transmitted to the support rod through the sliding block 1. At this time, the pulling force generated by the support rod increases, and it will move away from the hydraulic box 1 through the fixed plate, so that the hydraulic telescopic rod 2 is extended. The extended hydraulic telescopic rod 2 extracts the internal hydraulic oil of the hydraulic telescopic rod 3 through the hydraulic box 1, so that the hydraulic telescopic rod 3 drives the U-shaped sliding frame to slide along the inner wall of the sliding bracket 1, and the U-shaped sliding frame moves away from the arc-shaped toothed rod through the sliding block. At this time, the sliding block loses connection with the arc-shaped toothed rod, so that the pulling force generated by the support rod can drive the limit assembly and the adjusting assembly to reset. Through the application of the above-mentioned components, the orderliness of the equipment during resetting is guaranteed, and it is avoided that the various components are reset synchronously during resetting, causing the bottom contact assembly to shrink prematurely, resulting in a decrease in the supporting force of the equipment, and the analysis component and the drive component quickly descend and collide hard with the outer wall of the rail, causing damage to the equipment and instruments.

[0049] The present invention has the following beneficial effects:

[0050] (1) Before using the present invention, after ensuring the safety of the application environment, the device is placed on the rails, such as Figure 1As shown, the operation of the equipment is then controlled by an operating lever. When the equipment reaches the edge of the area, the staff turns on the power of the motor, and the motor drives the two L-shaped gear rods to slide to both sides along the inner wall of the installation groove through the gears. The outward-moving L-shaped gear rods will drive the hydraulic pipe, sliding block 1 and support rod to move outward synchronously, and the support rod drives the hydraulic box to move together through the fixed plate and the hydraulic telescopic rod 2. In this process, the hydraulic box 1 drives the sliding block 2 to slide along the inclined surface of the inclined plate, so that the sliding column slides downward along the inner wall of the sliding block 2, and at this time, the side wall of the contact box contacts the inner wall of the rail, and the contact boxes at the left and right ends contact the inner wall of the rail to form a clamping force, which will move the sliding rod; at the same time, when the contact box contacts the side wall of the rail, the support The rod is restricted and will no longer move, and when the L-shaped gear rod continues to move outward, the sliding block 1 will move along the inner wall of the hydraulic pipe in the direction of the gear, and the hydraulic oil inside the hydraulic pipe will be transmitted to the hydraulic telescopic rod 1 through the transmission pipe, causing the hydraulic telescopic rod 1 to extend, and the extended hydraulic telescopic rod 1 will force the frame and related components to slide upward along the outer wall of the sliding rod, and finally the sliding rod and the frame are completely separated. At this time, the staff can push one end of the frame to force the frame mechanism, the support mechanism and the power mechanism to rotate around the hydraulic telescopic rod 1. Through the application of the above components, when the equipment needs to turn, the support mechanism and the power mechanism can provide a support point, thereby reducing the impact of external vibration force on the instrument when the equipment turns.

[0051] (2) The present invention utilizes the characteristic that the contact box contacts the outer wall of the rail outwardly, and a contact assembly is arranged inside the device. When the contact box contacts the outer wall of the rail, the side wall of the contact plate will first contact the inner wall of the rail. At this time, the contact surface of the rail will force the contact plate to slide along the gap between the sliding plates, and the hydraulic oil inside the contact box will be squeezed to flow through the flow port. Moreover, as the pressure on each contact plate is different, the degree of inward sliding of the contact plate is also different, so that the contact plate finally forms the following Fig.11 In the state of medium G, through the application of the above components, it is ensured that the contact plate can adapt to the undulating surface of the inner wall of the rail when the equipment is extruding, thereby ensuring the stability of the contact surface of the equipment.

[0052] (3) The present invention utilizes the characteristic that the contact plate deforms after contacting the rail. When the contact plate contacts the outer wall of the rail, the contact plate at the top will extend to the top of the rail, forming a buckled state. Fig.11 In the middle F state, the friction contact of the contact plate is converted into a snap-on design, and the support mechanism and the power mechanism will generate a downward thrust during operation. The snap-on design increases the contact area while avoiding the situation where the friction between the contact plate and the rail is insufficient in the early stage. The support mechanism and the power mechanism generate a downward thrust, resulting in the power mechanism being unable to provide sufficient support for the equipment.

[0053] (4) The present invention utilizes the characteristic that after the device completes the turning, the motor will drive each component to reset. A safety mechanism is provided inside the device. When the motor drives the L-shaped gear rod to reset, the L-shaped gear rod will move toward the direction of the motor. During this process, the plane of the sliding block contacts the plane of the arc-shaped gear rod. Fig.10 As shown, the movement of the adjustment component, the limit component and the sliding block 2 is limited, and as the distance between the sliding block 2 and the L-shaped gear rod increases, the sliding block 1 will slide along the inner wall of the hydraulic pipe, so that the hydraulic pipe extracts the solution inside the hydraulic telescopic rod 1 through the transmission pipe, forcing the hydraulic telescopic rod 1 to contract, and the contraction of the hydraulic telescopic rod 1 will drive the frame and the driving component to reset synchronously, so that the driving wheel contacts the outer wall of the rail; and after the sliding block 1 moves outward to the outermost position, the contraction force of the contact component will be transmitted to the support rod through the sliding block 1. At this time, the pulling force generated by the support rod is increased, and it will be away from the hydraulic box 1 through the fixed plate, so that the hydraulic telescopic rod 2 will generate Extension. The extended hydraulic telescopic rod 2 draws the internal hydraulic oil of the hydraulic telescopic rod 3 through the hydraulic box 1, so that the hydraulic telescopic rod 3 drives the U-shaped sliding frame to slide along the inner wall of the sliding bracket 1, and the U-shaped sliding frame moves away from the arc-shaped gear rod through the sliding block. At this time, the sliding block loses connection with the arc-shaped gear rod, so that the tension generated by the support rod can drive the limit assembly and the adjustment assembly to reset. Through the application of the above components, the orderliness of the equipment is guaranteed during resetting, and it is avoided that the various components are reset synchronously during resetting, causing the bottom contact assembly to shrink prematurely, resulting in a decrease in the supporting force of the equipment, and the analysis assembly and the drive assembly quickly descend and collide hard with the outer wall of the rail, causing damage to the equipment and instruments.

[0097] Among them, after completing the direction change, the extension component 31 drives each component to reset, and the limit component 51 and the adjustment component 52 will control the reset speed and sequence of the power mechanism 3. The buckle design can avoid the situation where the friction force is insufficient in the early stage, and the support mechanism 2 and the power mechanism 3 will generate a downward thrust, resulting in the power mechanism 3 being unable to provide sufficient support force for the equipment.

[0098] For example 2, please refer to Figure 6 - Fig.11 The present invention is a combined measurement device based on a railway precision measurement network. On the basis of Example 1, the analysis component 11 includes a data analyzer 111 fixedly connected to the top of a frame 13, and the top of the frame 13 is rotatably connected to an operating rod 112. Before use, after ensuring the safety of the application environment, the device is placed on the rail, and then the operation detection of the device is controlled by the operating rod 112;

[0099] The two sides of the driving assembly 12 are fixedly connected with fixing frames 121, and the side walls of the two fixing frames 121 are rotatably connected with three driving wheels 122;

[0100] When in use, the staff can force the driving wheel 122 to rotate by operating the lever 112 , so that the driving wheel 122 drives the frame 13 and the data analyzer 111 to move along the outer wall of the rail through the fixing frame 121 .

[0101] The separation assembly 21 includes an inclined plate 213 fixedly connected to the inner wall of the mounting groove 212. When in use, the inclined plate 213 forces the control assembly 32 to drive the contact assembly 33 to contact the inner wall of the external rail.

[0102] The support assembly 22 includes a transmission pipe 222 connected to the side wall of the hydraulic telescopic rod 221. The extension of the hydraulic telescopic rod 221 will force the frame 13 to slide upward along the inner wall of the sliding rod 211, so that the sliding rod 211 slides away from the inner wall of the frame 13.

[0103] The transmission pipe 222 transmits hydraulic oil to the hydraulic telescopic rod 221, so that the hydraulic telescopic rod 221 is extended. The extended hydraulic telescopic rod 221 separates the sliding rod 211 from the frame 13, and the hydraulic telescopic rod 221 provides a rotation support point after separation.

[0104] The extension assembly 31 includes a hydraulic pipe 314 fixedly connected to the side wall of the L-shaped gear rod 313, a sliding block 315 is slidably connected to the inner wall of the hydraulic pipe 314, and the outer wall of the L-shaped gear rod 313 is meshed with the outer wall of the gear 312. During operation, the sliding block 315 will slide along the inner wall of the hydraulic pipe 314;

[0105] The extension assembly 31 includes a support rod 316 fixedly connected to the side wall of the sliding block 315. During operation, the motor 311 drives the L-shaped gear rod 313 to slide and extend along the inner wall of the mounting groove 212 through the gear 312. When the contact box 331 contacts the side wall of the rail, the support rod 316 is restricted and will no longer move. When the L-shaped gear rod 313 continues to move outward, the sliding block 315 will move along the inner wall of the hydraulic pipe 314 toward the direction of the gear 312, and the hydraulic oil in the hydraulic pipe 314 will be transmitted to the hydraulic telescopic rod 221 through the transmission pipe 222, so that the hydraulic extension rod 221 is The retracted rod 221 is extended, and the extended hydraulic telescopic rod 221 forces the frame 13 and the associated components to slide upward along the outer wall of the sliding rod 211, and finally the sliding rod 211 is completely separated from the frame 13. At this time, the staff can push one end of the frame 13 to force the frame mechanism 1, the support mechanism 2 and the power mechanism 3 to rotate around the hydraulic telescopic rod 221. Through the application of the above components, when the equipment needs to turn, the support mechanism 2 and the power mechanism 3 can provide a support point, thereby reducing the impact of external vibration force on the instrument when the equipment turns.

[0106] The control assembly 32 includes a hydraulic telescopic rod 2 323 connected to the side wall of the hydraulic box 1 322, and one end of the hydraulic telescopic rod 2 323 away from the hydraulic box 1 322 is fixedly connected to a fixing plate 324;

[0107] The control assembly 32 includes a sliding column 325 slidably connected to the inner wall of the sliding block 2 321. The top of the sliding column 325 is rotatably connected to a rolling column 326. The end of the support rod 316 away from the sliding block 1 315 is fixedly connected to the side wall of the fixed plate 324. When the equipment reaches the edge of the area, the staff turns on the power of the motor 311. The motor 311 drives the two L-shaped gear rods 313 to slide along the inner wall of the installation groove 212 to both sides through the gear 312. The outward-moving L-shaped gear rod 313 drives the hydraulic pipe 314 and the sliding block 1 31 5 and the support rod 316 move outward synchronously, and the support rod 316 drives the hydraulic box 1 322 to move in the same direction through the fixed plate 324 and the hydraulic telescopic rod 2 323. In this process, the hydraulic box 1 322 drives the sliding block 2 321 to slide along the inclined surface of the inclined plate 213, so that the sliding column 325 slides downward along the inner wall of the sliding block 2 321. At this time, the side wall of the contact box 331 contacts the inner wall of the rail, and the contact boxes 331 at the left and right ends contact the inner wall of the rail to form a clamping force, which will move the sliding rod 211;

[0108] When the extension component 31 extends outward, the control component 32 is driven to extend outward synchronously. During this process, the rolling column 326 will contact the inclined surface of the inclined plate 213 and force the sliding column 325 to slide downward along the inner wall of the sliding block 2 321 .

[0109] The contact assembly 33 includes a contact plate 334 slidably connected between a plurality of sliding plates 332. A flow port 333 is provided at the side walls of the plurality of sliding plates 332. The contact box 331 is used to contact the outer wall of the rail outward, and a contact assembly 33 is provided inside the device. When the contact box 331 contacts the outer wall of the rail, the side wall of the contact plate 334 will first contact the inner wall of the rail. At this time, the contact surface of the rail will force the contact plate 334 to slide along the gap between the sliding plates 332, and the hydraulic oil inside the contact box 331 will flow through the flow port 333 under pressure. As the pressure on each contact plate 334 is different, the degree of inward sliding of the contact plate 334 is also different, so that the contact plate 334 is finally formed as follows: Fig.11 In the state of middle G, through the application of the above components, it is ensured that when the equipment is extruding, the contact plate 44 can adapt to the undulating surface of the inner wall of the rail, thereby ensuring the stability of the contact surface of the equipment.

[0110] When the sliding post 325 moves outward, the side wall of the contact plate 334 is driven to contact the inner wall of the rail, so that the contact assembly 33 changes from the extrusion contact to the snap-fit ​​contact.

[0111] The limiting component 51 includes a U-shaped sliding frame 513 fixedly connected to the end of the hydraulic telescopic rod 3 511 away from the hydraulic box 1 322. The outer wall of the U-shaped sliding frame 513 is slidably connected to the inner wall of the sliding bracket 1 512. The inner wall of the U-shaped sliding frame 513 is provided with a sliding groove 1 514. The hydraulic telescopic rod 3 511 is synchronously contracted by the contraction of the hydraulic telescopic rod 2 323. The contact plate 334 is deformed after contacting the rail. When the contact plate 334 contacts the outer wall of the rail, the contact plate 334 at the top will extend to the top of the rail to form a buckled state, such as Fig.11 In the state of middle F, the friction contact of the contact plate 334 is converted into a snap-fit ​​design, and the support mechanism 2 and the power mechanism 3 will generate a downward thrust during operation. The snap-fit ​​design increases the contact area while avoiding the situation where the friction between the contact plate 334 and the rail is insufficient in the early stage, and the support mechanism 2 and the power mechanism 3 generate a downward thrust, resulting in the power mechanism 3 being unable to provide a sufficient support force for the equipment.

[0112] The adjusting component 52 includes a sliding block 521 slidably connected to the inner wall of the slide groove 514, an arcuate surface 522 is provided on the side wall of the sliding block 521, a spring 523 is fixedly connected to the side wall of the sliding block 521, and one end of the spring 523 away from the sliding block 521 is fixedly connected to the inner wall of the U-shaped sliding frame 513. After the device completes the steering, the motor 311 will drive the various components to reset. A safety mechanism 5 is provided inside the device. When the motor 311 drives the L-shaped gear rod 313 to reset, the L-shaped gear rod 313 will move in the direction of the motor 311. In this process, since the plane of the sliding block 521 contacts the plane of the arcuate gear rod 524, as shown in FIG. Fig.10 As shown, the movement of the adjustment component 52, the limit component 51 and the second sliding block 321 is limited, and as the distance between the second sliding block 321 and the L-shaped gear rod 313 increases, the first sliding block 315 will slide along the inner wall of the hydraulic pipe 314, so that the hydraulic pipe 314 extracts the solution inside the hydraulic telescopic rod 1 221 through the transmission pipe 222, forcing the hydraulic telescopic rod 1 221 to contract, and the contraction of the hydraulic telescopic rod 1 221 will drive the frame 13 and the driving component 12 to reset synchronously, so that the driving wheel 122 contacts the outer wall of the rail;

[0113] When the U-shaped sliding frame 513 drives the sliding block 521 to move outward, the sliding block 521 will slide along the outer wall of the arc-shaped gear rod 524 to limit the reset of the adjustment component 52. After the sliding block 1 315 moves outward to the outermost position, the contraction force of the contact component 33 will be transmitted to the support rod 316 through the sliding block 1 315. At this time, the pulling force generated by the support rod 316 is increased and will be away from the hydraulic box 1 322 through the fixing plate 324, so that the hydraulic telescopic rod 2 323 is extended. The extended hydraulic telescopic rod 2 323 extracts the hydraulic oil inside the hydraulic telescopic rod 3 511 through the hydraulic box 1 322, so that the hydraulic telescopic rod 3 511 drives the U-shaped sliding frame 513 to slide along the inner wall of the sliding bracket 512, and the U-shaped sliding frame 513 moves away from the arc-shaped gear rod 524 through the sliding block 521. At this time, the sliding block 521 loses connection with the arc-shaped gear rod 524, so that the tension generated by the support rod 316 can drive the limit component 51 and the adjustment component 52 to reset. Through the application of the above components, the orderliness of the equipment during resetting is guaranteed, and it is avoided that the various components are reset synchronously during resetting, causing the bottom contact component 33 to shrink prematurely, resulting in a decrease in the supporting force of the equipment, and the analysis component 11 and the drive component 12 quickly descend and collide hard with the outer wall of the rail, causing damage to the equipment and instruments.

[0114] A specific application of this embodiment is: before use, after ensuring the safety of the application environment, place the device on the rails, such as Figure 1As shown, the operation detection of the equipment is then controlled by the operating rod 112. When the equipment reaches the edge of the area, the staff turns on the power of the motor 311. The motor 311 drives the two L-shaped gear rods 313 to slide along the inner wall of the installation groove 212 to both sides through the gear 312. The outward-moving L-shaped gear rod 313 will drive the hydraulic pipe 314, the sliding block 1 315 and the support rod 316 to move outward synchronously, and the support rod 316 drives the hydraulic box 1 322 to move in the same direction through the fixed plate 324 and the hydraulic telescopic rod 2 323. In this process, the hydraulic box 1 322 drives the sliding block 2 321 to slide along the inclined surface of the inclined plate 213, so that the sliding column 325 slides downward along the inner wall of the sliding block 2 321. At this time, the side wall of the contact box 331 contacts the inner wall of the rail, and the contact boxes 331 at the left and right ends contact the inner wall of the rail to form a clamping force, which will move the sliding rod 211; at the same time, when the contact box 331 and When the side wall of the rail is in contact, the support rod 316 is restricted and will no longer move. When the L-shaped gear rod 313 continues to move outward, the sliding block 315 will move along the inner wall of the hydraulic pipe 314 toward the direction of the gear 312, and the hydraulic oil inside the hydraulic pipe 314 will be transmitted to the hydraulic telescopic rod 221 through the transmission pipe 222, so that the hydraulic telescopic rod 221 will be extended, and the extended hydraulic telescopic rod 221 will force the frame 13 and related components to slide upward along the outer wall of the sliding rod 211, and finally the sliding rod 211 is completely separated from the frame 13. At this time, the staff can push one end of the frame 13 to force the frame mechanism 1, the support mechanism 2 and the power mechanism 3 to rotate around the hydraulic telescopic rod 221. Through the application of the above components, when the equipment needs to turn, the support mechanism 2 and the power mechanism 3 can provide a support point, thereby reducing the impact of external vibration force on the instrument when the equipment turns.

[0115] By utilizing the characteristic that the contact box 331 contacts the outer wall of the rail outward, a contact assembly 33 is arranged inside the device. When the contact box 331 contacts the outer wall of the rail, the side wall of the contact plate 334 will first contact the inner wall of the rail. At this time, the contact surface of the rail will force the contact plate 334 to slide along the gap between the sliding plates 332, and the hydraulic oil inside the contact box 331 will flow through the flow port 333 under pressure. As the pressure on each contact plate 334 is different, the degree of inward sliding of the contact plate 334 is also different, so that the contact plate 334 finally forms the following Fig.11 In the state of middle G, through the application of the above components, it is ensured that when the equipment is extruding, the contact plate 44 can adapt to the undulating surface of the inner wall of the rail, thereby ensuring the stability of the contact surface of the equipment.

[0116] By utilizing the above-mentioned characteristic that the contact plate 334 deforms after contacting the rail, when the contact plate 334 contacts the outer wall of the rail, the contact plate 334 at the top will extend to the top of the rail, forming a buckle state, such as Fig.11 In the state of middle F, the friction contact of the contact plate 334 is converted into a snap-fit ​​design, and the support mechanism 2 and the power mechanism 3 will generate a downward thrust during operation. The snap-fit ​​design increases the contact area while avoiding the situation where the friction between the contact plate 334 and the rail is insufficient in the early stage, and the support mechanism 2 and the power mechanism 3 generate a downward thrust, resulting in the power mechanism 3 being unable to provide a sufficient support force for the equipment.

[0117] After the device completes the steering, the motor 311 will drive each component to reset. A safety mechanism 5 is provided inside the device. When the motor 311 drives the L-shaped gear rod 313 to reset, the L-shaped gear rod 313 will move toward the direction of the motor 311. During this process, the plane of the sliding block 521 contacts the plane of the arc gear rod 524. Fig.10 As shown, the movement of the adjusting component 52, the limiting component 51 and the sliding block 321 is limited, and as the distance between the sliding block 321 and the L-shaped gear rod 313 increases, the sliding block 315 will slide along the inner wall of the hydraulic pipe 314, so that the hydraulic pipe 314 extracts the solution inside the hydraulic telescopic rod 221 through the transmission pipe 222, forcing the hydraulic telescopic rod 221 to contract, and the contraction of the hydraulic telescopic rod 221 will drive the frame 13 and the driving component 12 to reset synchronously, so that the driving wheel 122 contacts the outer wall of the rail; and after the sliding block 315 moves outward to the outermost position, the contraction force of the contact component 33 will be transmitted to the support rod 316 through the sliding block 315, and the pulling force generated by the support rod 316 will increase, and will be away from the hydraulic box 322 through the fixing plate 324, so that the hydraulic The telescopic rod 2 323 is extended, and the extended hydraulic telescopic rod 2 323 draws the hydraulic oil inside the hydraulic telescopic rod 3 511 through the hydraulic box 1 322, so that the hydraulic telescopic rod 3 511 drives the U-shaped sliding frame 513 to slide along the inner wall of the sliding bracket 1 512, and the U-shaped sliding frame 513 moves away from the arc-shaped gear rod 524 through the sliding block 521. At this time, the sliding block 521 loses connection with the arc-shaped gear rod 524, so that the tension generated by the support rod 316 can drive the limit assembly 51 and the adjustment assembly 52 to reset. Through the application of the above-mentioned components, the orderliness of the equipment during resetting is guaranteed, and it is avoided that the various components are reset synchronously during resetting, causing the bottom contact assembly 33 to shrink prematurely, resulting in a decrease in the supporting force of the equipment, and the analysis assembly 11 and the drive assembly 12 quickly descend and collide hard with the outer wall of the rail, causing damage to the equipment and instruments.
