Description

Technical Field

[0001] The invention relates to the technical field of highway equipment, and in particular to a lane control machine. Background Art

[0002] As one of the basic modes of transportation in my country, expressways connect different cities and regions, shorten people's travel time, promote regional economic development, and accelerate cultural integration between regions. By the end of 2021, the total mileage of expressways in my country has reached 1.6 million kilometers, and the national expressway mileage is about 115,000 kilometers, covering 34 provincial / prefectural-level administrative regions across the country, and the total mileage continues to grow. As a toll lane, the toll collection system of the expressway has gradually changed from a manual toll collection system to an electronic toll collection system; in the electronic toll collection system, the lane controller plays a hub role. After receiving instructions from the computer system, the lane controller begins to control the work of various external devices, such as the switch of signal lights, the rise and fall of barrier machines, the switch of lane passage, and the sound and light alarm functions. Therefore, the normal operation of the lane controller is the basis for ensuring the normal use of the expressway.

[0003] Chinese invention patent specification CN 111739179A discloses a new embedded lane control machine, including a control machine, a support plate, a limit mechanism on the left side of the control machine, a lifting mechanism on the right side of the control machine, and a heat dissipation mechanism on the top of the control machine; the limit mechanism includes a shell, a cylinder, a sleeve and a first support rod; the lifting mechanism includes a shell, a slide, a screw, a threaded barrel, a slider, a second support rod, a first gear, a connecting rod and a second gear; when in use, by rotating the second gear toward the front side, the first gear is driven to rotate clockwise, and the threaded barrel moves outward, so that the support plate can move outward, and then the first support rod is driven to move outward, and at the same time, the sleeve follows the outer wall of the cylinder to move outward, so that the support plate moves more stably, and the device can leave a gap when the top and bottom ends of the control machine are installed. Obviously, this new embedded lane control machine needs to be lifted manually when it is transported, which increases the labor intensity of workers. During maintenance, the removal or insertion of the control machine adopts the form of sliding friction, which makes it inconvenient to install and disassemble the control machine. Summary of the invention

[0004] In view of the above-mentioned defects, the present invention aims to provide a lane controller, including a multi-function device, which is applied to different working occasions by utilizing different motion states of the multi-function device. When the multi-function device is in the extended state, the lane controller can be moved. At this time, the control machine body, the external shell and the multi-function device remain relatively stationary, which can avoid collision of the control machine body during transportation and protect its internal components from damage. The external shell and the ground maintain relative movement, which is convenient for the transportation of the lane controller. When the multi-function device is in the retracted state, the multi-function device forms upper and lower limit stops and rolling contact with the control machine body, and relative movement is formed between the control machine body, the external shell and the multi-function device, which is convenient for taking out or putting in the control machine body. The external shell and the ground maintain relative movement, which is convenient for the normal use of the lane controller.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a lane control machine, including a control machine body, which is a rectangular parallelepiped and is characterized in that it also includes an external shell and a multi-function device; the control machine body is arranged inside the external shell, and two multi-function devices are symmetrically arranged on both sides of the inner cavity of the external shell; the multi-function device includes a first telescopic component and a second telescopic component, the first telescopic component extends downward and is provided with a bottom wheel at the end, and the second telescopic component extends upward and is provided with a top wheel at the end; when the multi-function device is in an extended state, the bottom wheel is located below the lower end surface of the external shell, and the top wheel is located above the upper end surface of the external shell, and when the multi-function device is in a retracted state, the bottom wheel is located above the lower end surface of the external shell, the bottom wheel contacts the lower end surface of the control machine body and lifts the control machine body, and the top wheel contacts the upper end surface of the control machine box.

[0006] Furthermore, the upward extension direction of the second telescopic component is inclined upward extension. When the multi-function device is in the extended state, the top wheel exceeds the front end surface of the control machine body, and the bottom wheel also exceeds the front end surface of the control machine body.

[0007] Furthermore, the multifunctional device also includes a gear, a first rack, a second rack, and a slideway component; the gear is a spur gear; the first rack is vertically arranged and arranged on one side of the gear, the second rack is tilted and arranged on the upper half of the other side of the gear, and both are meshed with the gear; the back of the first rack is fixedly connected to the outside of the first telescopic component, and the back of the second rack is fixedly connected to the outside of the second telescopic component; the slideway component is symmetrically arranged on both sides of the inner cavity of the external shell, and the front of the slideway component is provided with a first slideway and a second slideway, the inner side surface of the first slideway is in sliding contact with the outer side surface of the first telescopic component, and the inner side surface of the second slideway is in sliding contact with the outer side surface of the second telescopic component, and the slideway component is connected to the gear by rotation. A shock-absorbing spring is arranged between the lower end of the first telescopic rod and the first telescopic cylinder; the end of the first telescopic rod extending vertically downward is equipped with a bottom wheel.

[0008] Furthermore, a first horizontal slide groove is opened above the center of gravity of the external shell, and a rotatable and slidable moving component is arranged in the first horizontal slide groove, and the moving component is fixedly connected to the middle part of the slide component; when the multi-function device is in a retracted state, the center of gravity of the control machine body is lower than the rotation center of the moving component.

[0009] Furthermore, the control machine body includes a control machine box and a control machine. The control machine box is a rectangular box with one side open, and an adjustable fixing device is arranged inside the box. The adjustable fixing device fixes control machines of different sizes inside the control machine box.

[0010] Furthermore, the adjustable fixing device includes a threaded barrel, a threaded rod, and a shock-absorbing component. The threaded barrel is fixedly connected to the inner surface of the control chassis, the threaded rod is threadedly connected to the threaded barrel, the far end of the threaded rod is fixedly connected to the shock-absorbing component, and the shock-absorbing component is in direct contact with the control machine body.

[0011] Furthermore, the external shell also includes a front baffle, and a second horizontal slide groove is provided at the top position of the two side plates of the external shell. A second rotating connection device is installed on one edge of the front baffle, and both ends of the second rotating connection device can be rotatably slidably arranged in the second horizontal slide grooves on both sides.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. When the multifunctional device of the lane controller is in the extended state, the bottom wheel installed on the first telescopic rod is below the lower end surface of the external shell. When the bottom wheel contacts the ground, the external shell can be suspended in the air. By pushing the external shell, the overall movement of the lane controller can be achieved, which is convenient for the operator to carry; the second telescopic rod component extends upward at an angle, and the top wheel can exceed the front end surface of the external shell. Since the bottom wheel also exceeds the front end surface of the external shell, the lane controller can be laid down for use to cope with the situation where the road slope is large, resulting in the high center of gravity of the lane controller and it is easy to fall, or there is a large single step on the road that needs to be climbed over, thereby increasing the terrain adaptability of the lane controller; a shock-absorbing spring is installed on the multifunctional device to offset the vibration and impact faced by the lane controller during movement.

[0014] 2. When the multifunctional device of the lane controller is in a retracted state, the bottom wheel installed on the first telescopic rod is above the lower end surface of the external shell, the lower end surface of the external shell contacts the ground, the bottom wheel contacts the bottom surface of the controller body and lifts the controller body, the top wheel contacts the top of the controller body, the top wheel and the bottom wheel complete the limiting of the controller body and form rolling contact with the controller body, which is convenient for the operator to take out or put in the controller body, and solves the inconvenience of installing or disassembling the existing controller.

[0015] 3. The multifunctional device of the lane control machine is connected to the external shell by a rotating and sliding connection. When the multifunctional device is in a slightly extended state, the bottom wheels are neither in contact with the ground nor with the bottom surface of the control machine body. At this time, the multifunctional device can be dragged to the edge of the front end surface of the external shell by sliding with the external shell, so that the operator can perform maintenance conveniently. When the multifunctional device is in a retracted state, if the ground on which the external shell is installed is not a horizontal plane but has a small inclination angle, the multifunctional device and the external shell can be rotated to keep the control machine body vertical, so that the operator can operate the control machine conveniently.

[0016] 4. The lane controller sets the controller and the control chassis in layers. By using an adjustable fixing device, different types of controllers can be fixed inside the control chassis. The control chassis replaces the controller to link with the external housing and the multi-function device. Since the shape and size of the control chassis are always constant, no matter what type of controller is installed inside the control chassis, the linkage between the control chassis and the external housing and the multi-function device can be guaranteed to be smooth. The external housing and the multi-function device do not need to be adaptively designed for the controller. For example, there is no need to change the position of each wheel in the retracted state of the multi-function device, thereby simplifying the overall design of the lane controller. In addition, external components such as wheels and external housings do not directly act on the controller, which can protect the controller from wear and possible direct impact during the operation of the multi-function device. The adjustable fixing device also includes a shock-absorbing component, which can offset the vibration or impact faced by the lane controller during use, thereby avoiding damage to the internal components of the controller, such as: the vibration or impact faced by the lane controller during movement, or the vibration or impact caused by passing vehicles when the lane controller is installed at a toll booth on a highway.

[0017] 5. The lane controller is provided with a multifunctional device and bottom wheels and top wheels are installed thereon. When the multifunctional device is in the extended state, the lane controller can be moved and has a certain terrain adaptability. When the multifunctional device is in the retracted state, the control machine is limited, and the rolling contact between the bottom wheels and the top wheels and the control machine body is utilized to facilitate the placement or removal of the control machine body. The multifunctional device is connected to the external shell by rotation and sliding, so that when the external shell is installed at a small angle, the multifunctional device can ensure the verticality of the control machine body, making it convenient for people to operate the control machine inside the control machine body. The present invention provides two sets of symmetrical and identical multifunctional devices to make the lane controller suitable for multiple working occasions and realize multiple functions using limited devices.

DETAILED DESCRIPTION

[0025] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the inventive product is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In the description of this embodiment, it should also be noted that, unless otherwise clearly specified and limited, the terms “set”, “connected” and “connected” should be understood in a broad sense.

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] refer to Figures 1 to 6 The present embodiment discloses a lane control machine, including a control machine body 100, which is a rectangular parallelepiped, and also includes an external shell 200 and a multifunctional device 300; the control machine body 100 is arranged inside the external shell 200, and two multifunctional devices 300 are symmetrically arranged on both sides of the inner cavity of the external shell 200; the multifunctional device 300 includes a first telescopic component 320 and a second telescopic component 350, the first telescopic component 320 extends downward and is equipped with a bottom wheel 330 at the end, and the second telescopic component 350 extends upward The multi-function device 300 is extended and has a top wheel 370 installed at the end; when the multi-function device 300 is in an extended state, the bottom wheel 330 is located below the lower end surface of the external shell 200, and the top wheel 370 is located above the upper end surface of the external shell 200; when the multi-function device 300 is in a retracted state, the bottom wheel 330 is located above the lower end surface of the external shell 200, the bottom wheel 330 contacts the lower end surface of the control machine body 100 and lifts the control machine body 100, and the top wheel 370 contacts the upper end surface of the control box 110.

[0029] Furthermore, the external housing 200 includes side panels 210, cross beams 220, a rear baffle 230, and a limiting component 240. The left and right side panels 210 are symmetrically arranged and fixedly connected together through four middle cross beams 220. The internal area surrounded by the four cross beams 220 is used to place the control machine body 100. The distance between the left and right side panels 210 is greater than the length of the control machine body 100. There are two cross beams 220 at the bottom, one of which is flush with the rear end surface of the control machine body 100, and the other cross beam 220 is located in the middle of the bottom surface of the control machine body 100. The distance between the two cross beams 220 is less than the width of the control machine body 100. The distance between the inner sides of the upper and lower side beams 220 is slightly larger than the height of the control machine body 100; the outer sides of the upper and lower side beams 220 flush with the rear end face of the control machine body 100 are fixedly connected with a rear baffle 230 to prevent the control machine body 100 from falling off from the rear end face of the external shell 200; the limiting component 240 is located on the inner sides of the four side beams 220 and is fixedly connected to the two bottom side beams 220 to limit the left and right movement of the control machine body 100; the above-mentioned size of the beam 220, size of the rear baffle 230, position of the beam 220, and position of the limiting component 240 do not affect the function of the multi-function device 300.

[0030] When the present embodiment is in use, the two first telescopic components 320 and the two second telescopic components 350 are telescopically moved synchronously, and both can use hydraulic components, spiral transmission components and other components that can realize telescopic movement. When the multifunctional device 300 is in the extended state, the lane control machine is in the working state of transportation; when the multifunctional device 300 is in the retracted state, the lane control machine is in the working state of normal use.

[0031] When the multifunctional device 300 is in the extended state, the first telescopic component 320 extends downward and reaches the maximum extension stroke, at which time the bottom wheel 330 is below the lower end surface of the external housing 200. When the bottom wheel 330 is in direct contact with the ground, the external housing 200 is not in contact with the ground; at this time, the external housing 200 can be pushed, and the lane controller moves forward as the bottom wheel 330 rolls with the ground. At the same time, the movement process of the second telescopic component 350 extending upward is the same as the movement process of the first telescopic component 320 extending downward. At this time, the top wheel 370 installed on the second telescopic component 350 is also above the upper end surface of the external housing 200. Since the top wheel 370 is not in contact with the ground, the top wheel 370 does not work, but the second telescopic component 350 can be used as a handle of the lane controller to facilitate dragging the entire device to facilitate the handling operation of the workers.

[0032] When the multi-function device 300 is in a retracted state, the downwardly extending end of the first telescopic component 320 enters above the lower end surface of the external shell 200, and the bottom wheel 330 also enters above the lower end surface of the external shell 200 at this time; as the first telescopic component 320 retracts, the bottom wheel 330 directly contacts the bottom surface of the control machine body 100; when the first telescopic component 320 reaches the maximum retraction stroke, the bottom wheel 330 lifts the control machine body 100 upward; at the same time, the retraction movement process of the first telescopic component 320 is the same as the retraction movement process of the first telescopic component 320. When the first telescopic component 320 reaches the maximum retraction stroke, the top wheel 370 directly contacts the top of the control machine body 100. At this time, the control machine body 100 is lifted by the bottom wheels 330 and is contacted by the top wheels 370. The bottom wheels 330 and the top wheels 370 complete the limiting of the control machine body 100. Since there is rolling friction between the bottom and top of the control machine body 100 and the bottom wheels 330 and the top wheels 370 respectively, when the control machine body 100 is pulled out or put in from the front, the friction between the control machine body 100 and the bottom wheels 330 and the top wheels 370 is small, which is convenient for taking out or putting in the control machine body 100, and facilitating the disassembly and installation of the control machine body 100.

[0033] As a further solution of this embodiment: the upward extension direction of the second telescopic part 350 is inclined upward extension. When the multi-function device 300 is in the extended state, the top wheel 370 exceeds the front end surface of the control machine body 100, and the bottom wheel 330 also exceeds the front end surface of the control machine body 100.

[0034] When the multifunctional device 300 is in the extended state, the second telescopic component 350 extends upward at an angle and reaches the maximum extension stroke. At this time, the top wheel 370 exceeds the front end surface of the external housing 200; at the same time, the bottom wheel 330 also exceeds the front end surface of the external housing 200. At this time, the lane controller can be laid down for use, the front end surface of the external housing 200 is the end close to the ground, and the bottom wheel 330 and the top wheel 370 are in direct contact with the ground. By pushing the external housing 200, the bottom wheel 330 and the top wheel 370 can roll with the ground, thereby driving the lane controller as a whole to move forward. This working mode is mainly used when the lane controller is pushed forward and the road ahead has a large slope or a large step appears. The lane controller can be laid down for use when being pushed on a road with a large slope to lower the center of gravity of the lane controller itself and prevent the lane controller from falling due to its high center of gravity on a road with a large slope. When encountering a single large step on the road ahead, a conventional lane controller can only pass the step by manual transportation. The lane controller can place the front end face of the control machine body 100 on the intersection of the step riser and the pedal, and control the inclination angle between the lane controller and the step riser by the rolling of the bottom wheel 330 and the ground. After finding a suitable inclination angle, the lane controller is flipped upward around the above-mentioned intersection. At this time, the top wheel 370 is in direct contact with the step pedal. By pushing the lane controller, the top wheel 370 and the step pedal are rolled, thereby driving the lane controller to move forward. When the entire lane controller is on the step pedal, the action of turning over the step is completed.

[0035] As a further solution of this embodiment: the multifunctional device 300 also includes a gear 310, a first rack 340, a second rack 360, and a slide component 380; the gear 310 is a spur gear; the first rack 340 is vertically arranged and arranged on one side of the gear 310, and the second rack 360 is inclined and arranged on the upper half of the other side of the gear 310, and both are meshed and connected with the gear 310; the back of the first rack 340 is fixedly connected to the outer side of the first telescopic component 320, and the back of the second rack 360 is fixedly connected to the outer side of the second telescopic component 350; the slide component 380 is symmetrically arranged on both sides of the inner cavity of the external shell 200, and the front of the slide component 380 is provided with a first slide 381 and a second slide 382, ​​the inner side surface of the first slide 381 is in sliding contact with the outer side surface of the first telescopic component 320, and the inner side surface of the second slide 382 is in sliding contact with the outer side surface of the second telescopic component 350, and the slide component 380 and the gear 310 are connected by rotation.

[0036] Furthermore, a rotating handle 313 is provided on the gear 310, the opening direction of the first slide 381 is vertical, and the opening direction of the second slide 382 is parallel to the movement direction of the second rack 360; the slide component 380 and the gear 310 are rotationally connected, and a detachable anti-falling component 312 is provided on the first rotating connection component 311 to prevent the gear 310 from falling off the slide component 380.

[0037] When the multifunctional device 300 is in the extended state, the gear 310 is rotated counterclockwise by rotating the handle 313. Since the gear 310 and the slideway component 380 are connected by rotation, the rotation of the gear 310 will not drive the slideway component 380 to rotate. The counterclockwise rotation of the gear 310 drives the first rack 340 to start extending vertically downward, and the first telescopic component 320 moves synchronously with the first rack 340 and slides vertically downward along the first slideway 381; when the maximum extension stroke of the first rack 340 is reached, the gear 310 stops rotating, the first rack 340 keeps meshing with the gear 310, and the first telescopic component 320 stops sliding in the first slideway 381; at this time, the bottom wheel 330 installed on the first telescopic component 320 is outside the external housing 200 and exceeds the front end surface of the control machine body 100. At the same time, the counterclockwise rotation of the gear 310 drives the second rack 360 to begin to extend upward at an angle, and the second telescopic component 350 moves synchronously with the second rack 360 and slides upward at an angle along the second slide 382; when the maximum extended stroke of the second rack 360 is reached, the gear 310 stops rotating, the second rack 360 remains engaged with the gear 310, and the second telescopic component 350 stops sliding in the second slide 382; at this time, the top wheel 370 is on the outside of the external shell 200 and exceeds the front end surface of the control machine body 100. At this time, the lane controller can realize the overall forward movement through the rolling of the bottom wheel 330 and the ground, so as to reduce the manual handling operation; when the lane controller is laid down, the cylindrical surfaces of the bottom wheel 330 and the top wheel 370 are in direct contact with the ground. This setting can lower the center of gravity of the lane controller, so that the lane controller can be easily moved on the road with a large slope, so as to prevent the device from falling due to the large road slope and the high center of gravity of the lane controller; when there is a large single step on the road ahead, the front end of the lane controller is placed on the intersection of the step riser and the pedal, and the movement of the bottom wheel 330 is used to adjust the inclination angle of the lane controller and the step riser, and the lane controller is turned around the above intersection at the optimal inclination angle, so that the top wheel 370 contacts the step pedal, and the lane controller is pushed onto the step pedal as a whole by the top wheel 370, so as to cross the step, further saving the labor of personnel. The lane controller realizes movement and has a certain terrain adaptability.

[0038] When the multifunctional device 300 is in the retracted state, the gear 310 is rotated clockwise by rotating the handle 313. Since the gear 310 and the slide member 380 are rotationally connected, the rotation of the gear 310 will not drive the slide member 380 to rotate. The clockwise rotation of the gear 310 drives the first rack 340 to begin to retract vertically upward, the first telescopic component 320 moves synchronously with the first rack 340, and slides vertically upward along the first slide 381, and the bottom wheel 330 installed on the first telescopic component 320 gradually enters the interior of the external shell 200; as the gear 310 rotates clockwise, the bottom wheel 330 directly contacts the bottom surface of the control machine body 100 and gradually lifts the control machine body 100 upward; when the maximum retraction stroke of the first rack 340 is reached, the gear 310 stops rotating, the first rack 340 keeps meshing with the gear 310, and the first telescopic component 320 stops sliding in the first slide 381; at this time, the control machine body 100 is lifted upward by the bottom wheel 330 and does not contact the beam 220 and the limiting component 240 in the external shell 200. At the same time, the clockwise rotation of the gear 310 drives the second rack 360 to begin to tilt and retract downward, the second telescopic component 350 moves synchronously with the second rack 360, and slides tilted downward along the second slide 382, ​​and the top wheel 370 installed on the second telescopic component 350 gradually enters below the upper end surface of the external shell 200; as the gear 310 rotates clockwise, the top wheel 370 begins to approach the top of the control machine body 100; when the maximum retraction stroke of the second rack 360 is reached, the gear 310 stops rotating, the second rack 360 remains engaged with the gear 310, and the second telescopic component 350 stops sliding in the second slide 382; at this time, the top wheel 370 directly contacts the top of the control machine body 100. At present, the bottom surface of the control machine body 100 directly contacts the bottom wheel 330 and is lifted upward by the bottom wheel 330, and the top of the control machine body 100 directly contacts the top wheel 370, and the control machine body 100 is limited by the position change of the bottom wheel 330 and the top wheel 370; by utilizing the rolling of the bottom surface of the control machine body 100 and the bottom wheel 330, by utilizing the rolling of the top of the control machine body 100 and the top wheel 370, and the limitation of the control body by the two, it is convenient to quickly take out and put in the control machine body 100, thereby overcoming the inconvenience of the prior art for the installation and disassembly of the embedded lane control machine.

[0039] As a further solution of this embodiment: the first telescopic component 320 and the second telescopic component 350 have the same structure; the first telescopic component 320 includes a first telescopic cylinder 321, a first telescopic rod 322, and a shock-absorbing spring 323, the inner surface of the first telescopic cylinder 321 is in sliding contact with the outer surface of the first telescopic rod 322, and a shock-absorbing spring 323 is arranged between the lower end of the first telescopic rod 322 and the first telescopic cylinder 321; the end of the first telescopic rod 322 extending vertically downward is installed with a bottom wheel 330.

[0040] Furthermore, the end of the first telescopic rod 322 extending vertically downward is detachably connected to three bottom wheels 330, and the three bottom wheels 330 are arranged in parallel along the front-to-back direction of the control machine body 100, and the end of the second telescopic rod extending obliquely upward is detachably connected to a top wheel 370; there is a small relative displacement between the first telescopic rod 322 and the first telescopic cylinder 321, and the relative displacement is used for the elastic deformation of the shock-absorbing spring 323, and there is a small relative displacement between the second telescopic rod and the second telescopic cylinder, and the relative displacement is used for the elastic deformation of the shock-absorbing spring 323.

[0041] When the multi-function device 300 is in an extended state, the three parallel bottom wheels 330 installed at the end of the first telescopic rod 322 are all below the lower end surface of the external shell 200, and the front bottom wheel 330 exceeds the front end surface of the control machine body 100. At this time, the shock-absorbing spring 323 is in an extended state; at the same time, the top wheel 370 installed at the end of the second telescopic rod is above the upper end surface of the external shell 200 and exceeds the front end surface of the control machine body 100. At this time, the shock-absorbing spring 323 is in an extended state. When the bottom wheel 330 contacts the ground, under the action of gravity of the external shell 200 and the control machine body 100, the first telescopic cylinder 321 moves slightly downward along the first telescopic rod 322, and the shock-absorbing spring 323 is in a slightly compressed state under the compression of the first telescopic cylinder 321. At this time, the bottom wheel 330 is still below the lower end surface of the external shell 200. When vibration or impact occurs during the forward movement of the lane controller, the first telescopic cylinder 321 continues to move downward along the first telescopic rod 322 under the action of vibration or impact, or the first telescopic rod 322 continues to move upward along the first telescopic cylinder 321 under the action of vibration or impact, thereby compressing the shock-absorbing spring 323 to deform. When the vibration or impact weakens, the shock-absorbing spring 323 begins to release the energy of compression deformation to restore the original extended state, and the first telescopic cylinder 321 or the first telescopic rod 322 is reset under the action of spring force, thereby reducing the influence of vibration and impact on the lane controller.

[0042] As a further solution of this embodiment: a first horizontal slide groove 250 is opened above the center of gravity of the external shell 200, and a rotatable and slidable moving component 260 is arranged in the first horizontal slide groove 250, and the moving component 260 is fixedly connected to the middle part of the slide component 380; when the multi-function device 300 is in the retracted state, the center of gravity of the control machine body 100 is lower than the rotation center of the moving component 260.

[0043] Furthermore, the first horizontal slide groove 250 is symmetrically opened on the left and right side plates 210 of the external shell 200. The first horizontal slide groove 250 includes a horizontal slide groove opened on the inner sides of the left and right side plates 210 and a horizontal strip-shaped through hole opened in the middle of the horizontal slide groove. The movable component 260 is a truncated cone-shaped slider. The front of the slider is fixedly connected to the middle of the slide component 380. A cylindrical protrusion is provided on the back of the slider. The cylindrical protrusion extends from the above-mentioned horizontal strip-shaped through hole. The cylindrical protrusion is bolted with an anti-loosening component 270. The anti-loosening component 270 prevents the movable component 260 from falling off from the first horizontal slide groove 250.

[0044] Under normal circumstances, the anti-loosening component 270 will not be opened when the multi-function device 300 performs telescopic movement. The anti-loosening component 270 will only be opened when the lane control machine is installed at a small angle or when the multi-function device 300 is being repaired.

[0045] When the multi-function device 300 is in the extended state, since the center of gravity of the external shell 200 is lower than the position of the first horizontal slide groove 250, the external shell 200 always remains vertically downward. Therefore, when the anti-loosening component 270 fails, the external shell 200 will not accidentally flip around the moving component 260.

[0046] When the multi-function device 300 is in the retracted state, the bottom wheels 330 and the top wheels 370 complete the limitation of the control machine body 100. Since the limited control machine body 100 has a low center of gravity, it can ensure that the limited control machine body 100 remains vertically downward in the initial stage. When the external shell 200 is installed at a small angle, first loosen the anti-loosening component 270, and the first telescopic component 320 remains vertical under the action of the center of gravity of the control machine body 100, and then tighten the anti-loosening component 270. At this time, the limited control machine body 100 always remains vertical, which is convenient for the operator to operate the control machine.

[0047] When the multi-function device 300 is being inspected, the bottom wheel 330 and the top wheel 370 are neither outside the external shell 200 nor in direct contact with the control machine body 100, but are in the middle position between the two positions. By loosening the anti-loosening component 270 and pushing the cylindrical protrusion on the moving component 260, the multi-function device 300 can slide along the first horizontal slide groove 250. When the multi-function device 300 is pushed to the edge of the front end surface close to the external shell 200, the operator can easily inspect the multi-function device 300, reset the multi-function device 300 after the inspection is completed, and finally tighten the anti-loosening component 270.

[0048] As a further solution of this embodiment: the control machine body 100 includes a control chassis 110 and a control machine 120. The control chassis 110 is a rectangular box with one side open, and an adjustable fixing device 130 is arranged inside the control chassis 110. The adjustable fixing device 130 fixes the control machines 120 of different sizes inside the control chassis 110.

[0049] When the present embodiment is in use, the control machine body 100 includes a control machine case 110 and a control machine 120, and the control machine 120 smaller than the control machine case 110 is placed in the control machine case 110. Since the sizes of different models of control machines 120 on the market are different, the control machine 120 smaller than the control machine case 110 can be placed in the control machine case 110, and the control machines 120 of different sizes can be fixed by the adjustable fixing device 130; when the control machine 120 needs to be taken out of the control machine case 110, the adjustable fixing device 130 can be opened. When the multi-function device 300 is in the retracted state, the control machine 120 in the control machine case 110 can be taken out or put in at the same time by limiting the control machine case 110 and taking it out or putting it in, so as to facilitate the installation and removal of the control machine 120.

[0050] As a further solution of this embodiment: the adjustable fixing device 130 includes a threaded barrel 131, a threaded rod 132, and a shock-absorbing component 133. The threaded barrel 131 is fixedly connected to the inner surface of the control chassis 110, the threaded rod 132 is threadedly connected to the threaded barrel 131, the far end of the threaded rod 132 is fixedly connected to the shock-absorbing component 133, and the shock-absorbing component 133 is in direct contact with the control machine body 100.

[0051] Furthermore, the threaded cylinder 131 is fixedly connected to the upper surface of the inner cavity of the control chassis 110 , and a shock absorbing component 133 is fixedly connected to the lower surface of the inner cavity of the control chassis 110 . The shock absorbing component 133 may be a rubber column.

[0052] The length of the threaded rod 132 extending from the threaded barrel 131 is used to adapt the control machine 120 of different sizes. When the size of the control machine 120 is greatly different from that of the control machine box 110, a longer threaded rod 132 can be replaced to adapt and adjust the control machine 120. The elastic deformation of the rubber column on the threaded rod 132 and the lower surface of the inner cavity of the control machine box 110 can reduce the impact of external vibration or impact on the control machine 120 during the operation of the lane control machine 120. The adjustable fixing device 130 is set on the upper surface of the inner cavity of the control machine box 110, so that the center of gravity of the control machine 120 can be lower than the center of gravity of the control machine box 110, which is conducive to lowering the center of gravity of the control machine body 100 below the center of rotation of the moving part 260.

[0053] As a further solution of this embodiment: the external shell 200 also includes a front baffle plate 280, a second horizontal slide groove 290 is provided at the top position of the side panel 210, and a second rotating connecting component 281 is installed at one edge of the front baffle plate 280, and both ends of the second rotating connecting component 281 can be rotatably slidably arranged in the second horizontal slide grooves 290 on both sides.

[0054] Furthermore, a locking component 282 is provided on the other edge of the front baffle 280 , and the locking component 282 is connected to the external housing 200 by bolts.

[0055] When the multi-function device 300 is in the extended state, the front baffle 280 is not flipped over, the locking part 282 is closed, and the front baffle 280 completely covers the open surface of the control chassis 110. At this time, when the lane controller is moved or laid down for movement, the front baffle 280 will prevent the control machine 120 from falling off from the control chassis 110, and prevent the control chassis 110 from falling off from the external shell 200.

[0056] When the multi-function device 300 is in the retracted state, the locking component 282 is opened, the front baffle 280 is flipped upward, and the front baffle 280 is pushed to slide in the second horizontal slide groove 290. When the front baffle 280 completely covers the top wheel 370, the front baffle 280 realizes sunshade or rain protection for the entire lane control machine.
