Description

Technical Field

[0001] This invention relates to the field of emergency traffic equipment technology, specifically to a temporary emergency traffic guidance device. Background Technology

[0002] Temporary traffic control equipment is often used in situations such as when traffic lights are broken, during routine maintenance, temporary construction, or road repairs. Therefore, this equipment needs to be easy to move and stable during operation. Since the working environment is generally on a flat road without fixed equipment, its own weight needs to be increased to improve stability; however, this obviously conflicts with ease of movement. This leads to temporary traffic control equipment typically falling into the following two categories.

[0003] 1. To achieve ease of movement, some manufacturers use expensive materials to reduce their weight, sometimes even employing costly materials for transport. However, their stability during operation is poor, making them difficult to secure in harsh weather conditions, sometimes requiring external weight-bearing to achieve stability.

[0004] 2. It has good stability, which is improved by increasing its weight. However, as it is a temporary emergency traffic guidance device, it needs to be moved from time to time to work in different environments; the transportation process is relatively difficult.

[0005] Based on this, the present invention designs a temporary emergency traffic guidance device to solve the above problems. Summary of the Invention

[0007] As a further embodiment of the present invention, the moving assembly comprises two sets, each set including a driven lead screw.

The first telescopic rod and the moving block are connected by a first connecting rod. A driven gear is fixedly disposed on the same side end of both driven lead screws. When the driven lead screw rotates, the height of the roller can be adjusted by the first connecting rod and the first telescopic rod.

[0008] As a further embodiment of the present invention, the driving mechanism includes a drive screw, which is rotatably disposed on the inner side wall of the base, and a slot is formed on the side wall of the base corresponding to the position of the drive screw; a driving member is externally connected to the base, which can drive the drive screw to rotate through the slot; a drive gear is slidably disposed on the drive screw, and the drive gear meshes with two driven gears simultaneously; the driving device also includes a switching device for switching the driven member.

[0009] As a further embodiment of the present invention, the fixing mechanism includes a drive block that slides on the inner sidewall of the base and is threadedly connected to the drive screw. A second connecting rod is rotatably provided at one end of the drive block away from the drive gear, and a first fixing block is hinged to the other end of the second connecting rod. The first fixing block is fixedly provided at the telescopic end below the second telescopic rod, and the second telescopic rod is provided inside the base. A suction cup is fixedly provided at the lower end of the first fixing block.

[0010] As a further embodiment of the present invention, the fixing device is further provided with a cleaning device for auxiliary suction cup adsorption. The cleaning device includes a cleaning bucket, which is fixedly connected to the base. A tenon is radially slidably disposed at the middle position of the cleaning bucket via a third spring. The tenon includes a pair of wedge-shaped surfaces and a guide post, and a limiting groove is provided at the middle position of the tenon. A first piston and a second piston are axially sealed and slidably disposed on the inner wall of the cleaning bucket. The first piston can be engaged in the limiting groove in the middle of the tenon. The first piston and the second piston are connected by a fourth spring. The inner side of the first piston is cleaned by the cleaning bucket. The end walls are connected by a fifth spring; the cavity formed by the first piston and the cleaning bucket is a water cavity; the cavity between the first piston, the second piston, and the side wall of the cleaning bucket is an air cavity; a cleaning tube is connected to the outside of the cleaning bucket, and the cleaning tube is provided with a one-way inlet in both the air cavity and the water cavity. The other end of the cleaning tube is located in the middle of the upper part of the suction cup, so as to facilitate the cleaning tube to perform point cleaning on the suction cup's adsorption position; a one-way inlet is provided in both the air cavity and the water cavity, wherein the one-way inlet of the water cavity is connected to a water tank, and the one-way inlet of the air cavity is directly connected to the outside; the second piston is connected to a pushing device.

[0011] As a further embodiment of the present invention, the pushing device includes a piston rod that passes through the cleaning bucket and is fixedly connected to the second piston; a piston cylinder with an opening groove is fixedly disposed at one end of the piston rod in the cleaning bucket, and a wedge-shaped first stop is fixedly disposed on the portion of the piston rod located within the opening groove of the piston cylinder; a wedge-shaped second stop is fixedly disposed on the portion of the piston cylinder located below its opening groove, and the wedge-shaped surfaces of the first stop and the second stop are opposite to each other; the pushing device also includes a fifth telescopic rod fixedly disposed on the drive block, and a trigger block is rotatably disposed at the end of the fifth telescopic rod via a torsion spring, the trigger block being able to rotate only in one direction relative to the fifth telescopic rod by a fixed angle.

[0012] As a further embodiment of the present invention, the signal light is composed of two identical signal light components, each of which has a semi-cylindrical tube at its lower end. When the two signal light components are raised, they form a complete signal light. One of the semi-cylindrical tubes is rotatably connected to a bracket to prevent interference when the two semi-cylindrical tubes rotate around the bracket. The two semi-cylindrical tubes can form a cylindrical tube when vertical. Both semi-cylindrical tubes are rotatably mounted on a bracket fixed to the base. Above the second telescopic rod, there is also a telescopic end with a first fixing block installed. The first fixing block is connected to the driving block via another identical second connecting rod. When the driving block moves, it can drive both ends of the second telescopic rod to extend or shorten simultaneously. A limiting cylinder is provided at the upper end of the first fixing block, and the limiting cylinder has a clearance groove to avoid the bracket. When the limiting cylinder moves upward, it can drive the two semi-cylindrical tubes to raise the signal light components on both sides, forming a complete signal light. The base also has symmetrically arranged lamp slots for accommodating the horizontally positioned signal light components.

[0013] As a further embodiment of the present invention, the switching device includes a first spring disposed between the side wall of the base connecting the drive screw and the drive gear; the switching device also includes an adjusting wheel fixedly connected to the drive gear and sleeved with the drive screw, and a rotating shaft rotatably connected to the base via a bearing seat, a drive frame fixedly disposed on the rotating shaft, the drive frame including a first shift fork and a second shift fork, the first shift fork and the second shift fork being connected by a third telescopic rod, the third telescopic rod being slidably connected to the first shift fork; the telescopic connecting sleeve is rotatably connected to the second shift fork, and the lower end of the second shift fork is vertically slidable with the base via the second shift fork. The connection is as follows: the upper end of the second shift fork has a guide surface to facilitate the adjustment wheel to move laterally when the second shift fork moves vertically; the switching device also includes a moving shaft connected between the two moving blocks, the reciprocating motion of the moving shaft can drive the first shift fork to rotate reciprocally around the bearing seat axis; the driving screw has a prism section, and is slidably connected to the driving gear through the prism, so that the driving gear cannot rotate with the driving screw continuously; the switching device also includes a sleeve with one end fixed to the driving block and sleeved on the driving screw, the sleeve is used to drive the driving gear to slidely connect with the driving screw when the driving block is about to disengage from the threaded connection with the driving screw.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The driving screw rotates, which drives the driven screw to rotate through the gear transmission. The rotation of the driven screw causes the moving blocks on the same side to move closer to each other. During the movement of the moving blocks, the first telescopic rod is shortened through the first connecting rod, thereby controlling the extension and retraction of the roller, eliminating the influence of the roller on the stability of the equipment, and making the equipment easy to move and transport.

[0016] 2. The rotation of the drive screw causes the drive block to move away from the drive gear. The drive block, via the second connecting rod, extends the second telescopic rod, causing the suction cup, which is fixedly connected to the second telescopic rod, to move downwards and adhere to the ground. This adhesion of the suction cup to the ground improves the stability of the device during operation.

[0017] 3. By rotating the active lead screw, the drive block moves away from the active gear. The drive block pushes the second piston through the fifth telescopic rod and the first stop block, controlling the orderly operation of the cavity and water cavity. The cleaning pipe cleans the area adsorbed by the suction cup, improving the adhesion between the suction cup and the ground, thereby further improving the stability of the equipment during operation.

[0018] 4. By rotating the active lead screw, the drive block moves away from the active gear. The drive block extends the second telescopic rod through the second connecting rod, causing the limiting cylinder fixed at the upper end of the second telescopic rod to move upward. During the upward movement of the limiting cylinder, the semi-cylinder moves in a circular motion around the rotation groove of the bracket, thereby raising the signal light assemblies on both sides of the two drivable semi-cylinders to form a complete signal light.

[0019] 5. The rotation of the driving screw transmits power to the driven screw via gears. The rotation of the driven screw causes the moving block near the gear to move away from the gear. At the same time, the moving shaft moves along the same trajectory as the moving block. The moving shaft pushes the first shift fork, causing the drive frame to reciprocate around the rotation axis. The first shift fork transmits the driving force to the second shift fork via the third telescopic rod, causing the second shift fork to move downwards, releasing the second shift fork from restricting the adjusting wheel. Furthermore, due to the action of the first spring, the driving gear disengages from the driving screw, interrupting the power transmission between the driving screw and the driving gear, thus realizing the conversion of power.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-10 The present invention provides a technical solution: a temporary emergency traffic indicator device, comprising a traffic light, a base 2, and a movable component, wherein the traffic light is disposed on the upper end face of the base 2, and the movable component is disposed on the lower end face of the base 2; characterized in that: a driving mechanism for driving the movable component to extend and retract is disposed inside the base 2; a fixing mechanism driven by the driving mechanism is also disposed inside the base 2; the fixing mechanism is used to fix the base 2 on a plane after the movable component retracts into the base 2, and can be released from fixing before the movable component extends out of the base 2.

[0035] The main technical means used in this invention are:

[0036] Assume the initial state of base 2 is: the moving component extends beyond the outer side of base 2, making it easy to move but difficult to position. At this point, it is necessary to retract the moving component into base 2 to enhance its stability.

[0037] The user needs to drive the drive unit to move, causing the moving component to slowly retract into the base 2. Once the moving component is retracted into the base 2, the drive mechanism can drive the fixing device to fix the base 2, thereby stabilizing the base 2. When the base needs to be moved, simply drive the drive unit to move, causing the fixing device to release the fixing of the base 2. After the fixing of the base 2 is released, the moving component can extend out of the base 2, thus achieving the technical effect of easy transportation.

[0038] This invention enables the device to maintain both mobility and stability on a flat surface by switching between the operation of the moving component and the fixed device. This allows the device to better maintain its mobility while also providing more stable indicating performance.

[0039] As a further invention of this invention, the movable assembly comprises two sets, each set including a driven lead screw 15. The driven lead screw 15 has two sections of threads with opposite directions at both ends, and each section of thread is threadedly connected to a moving block 33. All moving blocks 33 are slidably connected to the base 2. A second fixing block 31 is rotatably disposed on the driven lead screw 15 portion corresponding to the outer end of each section of thread. A first telescopic rod 25 is fixedly disposed at the lower end of each second fixing block 31. Each first telescopic rod 25 has a... A roller 3 is provided to facilitate the movement of the base 2. The first telescopic rod 25 and the moving block 33 are connected by a first connecting rod 28. The purpose of the sliding connection between the moving block 33 and the base 2 is to reduce the torque on the first connecting rod 28 when the moving block 33 is threaded with the driven screw 15, thereby improving the service life of the first connecting rod 28. A driven gear 17 is fixedly provided on the same side end of both driven screws 15. When the driven screw 15 rotates, the height of the roller 3 can be adjusted by the first connecting rod 28 and the first telescopic rod 25.

[0040] Working process: When the two driven lead screws 15 rotate simultaneously, it can ensure that the moving blocks 33 on the two driven lead screws move synchronously, thereby making the second telescopic rod extend (the moving blocks on the same lead screw move in opposite directions) or shorten (the moving blocks on the same driven lead screw move in opposite directions), further enabling the roller 3 to complete the extension or retraction.

[0041] The transmission method of driven screw 15 and moving block 33 is simple and reliable. In the actual extension and retraction process of roller 3, roller 3 needs to overcome the huge gravity of base 2 when it extends. The transmission method of driven screw 15 and moving block 33 is a long-stroke but labor-saving transmission method, which can effectively reduce the condition restrictions during the extension process of roller 3. In addition, during the extension process of roller 3, the self-locking performance of the moving component when it extends can be improved by setting the thread on driven screw 15 to a triangular thread, thereby greatly improving the reliability and safety of roller 3 when it extends or retracts.

[0042] The user drives the drive screw 26 to rotate the drive gear 20. The drive gear 20 transmits power to the driven screw 15, which is fixedly connected to the driven gear 17, through the driven gear 17. The driven screw 15 rotates to drive the moving block 33 to move towards or away from each other. The movement of the moving block 33 controls the extension and retraction of the first telescopic rod 25 through the first connecting rod 28, thereby controlling the retraction or extension of the roller 3.

[0043] As a further invention of this invention, the driving mechanism includes a drive screw 26, which is rotatably mounted on the inner side wall of the base 2. A slot 2-1 is provided on the side wall of the base 2 at a position corresponding to the drive screw 15. A driving component that can drive the drive screw 26 to rotate through the slot 2-1 is connected to the base 2. Any device capable of driving the drive screw 26 to rotate is acceptable, such as a crank handle. A drive gear 20 is slidably mounted on the drive screw 26. The sliding connection can be a spline connection or a key connection. Its main function is to enable the drive screw 15 and the drive gear 20 to achieve relative sliding motion under the action of external force. The drive gear 20 meshes with two driven gears 17 simultaneously. The driving device also includes a switching device for switching the driven component.

[0044] When using this invention:

[0045] In the initial state (i.e., the moving component extends out of the base 2), when it is necessary to drive the moving component to retract, it is only necessary to insert the driving component through the slot 2-1 and drive the driving screw 26 to rotate. When the driving screw 26 rotates, the driving screw 26 will drive the driving gear 20 to rotate. The rotation of the driving gear 20 will drive the two driven gears 17 to rotate synchronously. Furthermore, it will drive the two driven screws 15 to rotate synchronously, thereby realizing the retraction of the component.

[0046] Since most areas using temporary traffic guidance equipment lack adequate infrastructure and are prone to power outages, the advantage of this method is that the external drive mechanism greatly improves the equipment's flexibility, allowing it to serve more locations in need. Furthermore, the drive screw 26 requires less driving force, thus reducing the manual labor intensity during operation.

[0047] As a further invention of this case, the fixing mechanism includes a drive block 30 that slides on the inner wall of the base 2 and is threadedly connected to the drive screw 26 (the drive block 30 cannot be threadedly connected to the drive screw 26 all the time; its threaded connection to the drive screw 26 is only possible when the drive screw 26 loses or is about to lose its drive over the moving component; before that, the drive screw 26 is rotatably connected or sleeved with the drive block 30). A second connecting rod 9 is rotatably provided at one end of the drive block 30 away from the drive gear 20, and a first fixing block 12 is hinged to the other end of the second connecting rod 9. The first fixing block 12 is fixedly provided at the telescopic end below the second telescopic rod 11, and the second telescopic rod 11 is provided inside the base 2. A suction cup 27 is fixedly provided at the lower end of the first fixing block 12.

[0048] In this section, after the moving component completes its retraction, the switching mechanism will switch the driven component of the drive screw 26 from the moving component to the fixed component. The drive screw 26 continues to rotate, thereby driving the drive block 30 to move linearly away from the drive gear 20 along the axis of the drive screw 26 (e.g., Figure 5 As shown in the figure, the second telescopic rod 11 is extended by the second connecting rod 9 and the driving block 30, and the suction cup 27 moves downward and finally adheres to the ground, thereby achieving the purpose of fixing the base 2.

[0049] This part has a simple structure, is easy to maintain, and has reliable and stable transmission. The suction cup 27 provides an overall windproof fixation for the base 2, which allows the base 2 to maintain stable guidance in the face of air pressure changes caused by fast-moving traffic.

[0050] Since road conditions are usually not good in places where temporary traffic guidance equipment is needed, and dust on the ground can affect the adsorption effect of suction cup 27, in order to solve this technical problem:

[0051] As a further invention of this invention, the fixing device is also provided with a cleaning device for adsorption by an auxiliary suction cup 27. The cleaning device includes a cleaning bucket 19, which is fixedly connected to the base 2. A tenon 41 is radially slidably disposed in the middle position of the cleaning bucket 19 via a third spring 42. The tenon 41 includes a pair of wedge-shaped surfaces 41-1 and guide posts 41-3. A limiting groove 41-2 is provided in the middle position of the tenon 41. A first piston 36 and a second piston 37 are axially sealed and slidably disposed on the inner wall of the cleaning bucket 19. The first piston 36 can be engaged in the limiting groove 41-2 in the middle of the tenon 41. The first piston 36 and the second piston 37 are connected by a fourth spring 38. The inner end walls of the cleaning bucket 19 are connected by a fifth spring 39; the cavity formed by the first piston 36 and the cleaning bucket 19 is a water cavity; the cavity between the first piston 36, the second piston 37 and the side wall of the cleaning bucket 19 is an air cavity; the cleaning bucket 19 is externally connected to a cleaning tube 40, which has a one-way inlet in both the air cavity and the water cavity, and the other end of the cleaning tube 40 is located at the middle position of the upper part of the suction cup 27, so as to facilitate the cleaning tube 40 to perform fixed-point cleaning on the suction position of the suction cup 27; both the air cavity and the water cavity are provided with one-way inlets, wherein the one-way inlet of the water cavity is externally connected to a water tank 10, and the one-way inlet of the air cavity is directly connected to the external device; the second piston 37 is externally connected to a pushing device.

[0052] Work process: such as Figure 5 Combination Figure 9 As shown: When the drive block moves to the left ( Figure 5(From the perspective of the center) the piston rod 18 moves, and the second piston 37 moves away from the drive gear 20 under the action of thrust. Under the action of thrust, the air between the first piston 36 and the second piston 37 is compressed first, and the compressed air in the cavity is squeezed out from the top of the suction cup 27 through the cleaning tube 40, thereby achieving the technical effect of blowing away the dust on the suction station of the suction cup 27; when the second piston 37 contacts the wedge-shaped surface 41-1 of the tenon 41 and pushes the tenon 41 towards the inner wall of the cleaning bucket 19 under the action of thrust, the first piston 36 is released from the restraint of the limiting groove 41-2, and the first piston 36 moves in the direction of thrust under the action of the fourth spring 38. During the movement of the first spring 36, the water in the water cavity is squeezed out from the top of the suction cup through the cleaning tube 40, thereby achieving the technical effect of washing away and cleaning the dust on the suction station of the suction cup 27, and finally making the fixation effect of the suction cup 27 on the base 2 more stable.

[0053] This technology cleans the lower part of the suction cup 27 by driving the movement of the drive block 30. The cleaning method involves blowing followed by rinsing, which is highly efficient and uses readily available resources. It can improve the operational stability of the equipment, save on control components, and maintain a simple structure while improving the overall performance of the equipment.

[0054] As a further invention of this case, the pushing device includes a piston rod 18, which passes through a cleaning bucket 19 and is fixedly connected to the second piston 37; a piston cylinder 22 with an opening groove is fixedly provided at one end of the piston rod 18 in the cleaning bucket 19, and a wedge-shaped first stop 21 is fixedly provided at the part of the piston rod 18 located in the opening groove of the piston cylinder 22; a wedge-shaped second stop 23 is fixedly provided at the part of the piston cylinder 22 located below its opening groove, and the wedge-shaped surfaces 41-1 of the first stop 21 and the second stop 23 are opposite to each other; the pushing device also includes a fifth telescopic rod 24-2 fixedly provided on the drive block 30, and a trigger block 24-1 is rotatably provided at the end of the fifth telescopic rod 24-2 via a torsion spring 24, and the trigger block 24-1 can only rotate unidirectionally by a fixed angle relative to the fifth telescopic rod 24-2.

[0055] During the cleaning process of the cleaning device, since cleaning occurs before adsorption, if the piston rod 18 is continuously driven by the drive block 30, the drive screw 26 will inevitably have a period of idle stroke during the adsorption process of the suction cup 27, waiting for the suction cup 27 to adsorb. This will increase the overall size of the equipment and affect its convenience. To solve this technical problem, the technical means in this section are as follows:

[0056] When the drive screw 26 rotates, it causes the drive block 30 to move away from the drive gear 20. A fifth telescopic rod 24-2 is fixedly connected to the drive block 30. The drive block 30, through the fifth telescopic rod 24-2, the trigger block 24-1 on the fifth telescopic rod 24-2, and the first stop block 21, causes the piston rod 18, fixedly connected to the first stop block 21, to move axially away from the drive gear 20. The piston rod 18 pushes the second piston 37 to complete the cleaning work. The trigger block 24-1 pushes the first stop block 21 and the piston rod 18 to move axially away from the drive gear 20. When the trigger block 24-1 reaches the second stop block 23, which is fixedly connected to the piston cylinder 22, the wedge-shaped surface 41-1 of the second stop block 23 causes the fifth telescopic rod 24-2 to shorten, causing the trigger block 24-1 to disengage from the first stop block 21. Under the action of the third spring 42 and the fourth spring 38 inside the cleaning tank 19, the piston rod 18, which is fixedly connected to the first stop block 21, returns to its initial state. At this time, the trigger block 24-1 continues to move until it is also completely disengaged from the second stop block 23. It should be noted that during the return stroke of the drive block, (such as...) Figure 6 The trigger block 24-1 can rotate relative to the torsion spring 24, thereby passing over the second stop block 23 and the piston cylinder 22 (this part is a conventional method and will not be described in detail).

[0057] This part not only enables the drive block 30 to drive the piston rod 18, but also controls the size of the equipment and makes the whole process reversible, which greatly enhances the stability of the equipment.

[0058] In reality, the use of a signal light implies that base 2 is securely fixed. If base 2 is not securely fixed, the signal light will not be used. Furthermore, signal lights erected in the traditional manner cause significant inconvenience during transportation, increasing the likelihood of damage and reducing the number of bases 2 that can be transported with the same equipment. To solve this technical problem:

[0059] As a further invention of this case, the signal light is composed of two completely equal signal light components 1, each of which has a semi-cylindrical tube 4 at its lower end; the two signal light components 1 can form a complete signal light when raised, and one of the semi-cylindrical tubes 4 is rotatably connected to the bracket 6 through a positioning tube 4-1 to avoid interference when the two semi-cylindrical tubes 4 rotate around the bracket 6; the two semi-cylindrical tubes 4 can form a cylindrical tube 4 in a vertical state; both of the two semi-cylindrical tubes 4 are rotatably mounted on the bracket 6 fixed on the base 2; there is also a bracket above the second telescopic rod 11 with a first... The telescopic end of a fixed block 12 is connected to the drive block 30 via another identical second connecting rod 9. When the drive block 30 moves, it can drive both ends of the second telescopic rod 11 to extend or shorten simultaneously. The upper end of the first fixed block 12 is provided with a limiting cylinder 7, and the limiting cylinder 7 is provided with a clearance groove 7-1 to avoid the bracket 6. When the limiting cylinder 7 moves upward, it can drive the two semi-cylindrical cylinders 4 to raise the signal light assemblies 1 on both sides to form a complete signal light. The base 2 is also symmetrically provided with lamp slots 8 for placing the signal light assemblies 1 in a horizontal state.

[0060] When using this part: Before the suction cup 27 adsorbs, the signal light assembly 1 should be in the lamp slot 8. Drive the drive screw 26 to move the drive block 30 away from the drive gear 20. The drive block 30 is rotatably connected to the second connecting rod 9. The second connecting rod 9 is hinged to the first fixed block 12. The first fixed block 12 is fixedly connected to the second telescopic rod 11. The drive block 30 extends both ends of the second telescopic rod 11 through the second connecting rod 9 and the first fixed block 12.

[0061] Since the entire process of the extension of the lower end of the second telescopic rod 11 has been clearly explained in the above document, only the extension process of the upper end of the second telescopic rod 11 will be briefly described now:

[0062] The upper end of the second telescopic rod 11 is fixedly connected to a limiting cylinder 7. The limiting cylinder 7 has a clearance groove 7-1 that avoids the bracket at the corresponding position. When the second telescopic rod 11 extends, it pushes the limiting cylinder 7 to move upward. The limiting cylinder 7 pushes the two semi-cylindrical cylinders 4 to reciprocate around the rotation groove 5 of the bracket in a quarter circle, so that the signal light assembly 1 forms a complete signal light (e.g., Figure 3 (As shown).

[0063] This section establishes a reliable support connection between the limiting cylinder 7 and the signal light assembly 1. Before the base 2 is fixed, the signal light should not be in operation; it should be in a retracted state to reduce the difficulty of transporting the base 2. Once the base 2 is fixed, the signal light reliably lifts itself, stabilizing the equipment's operation. The lifting action of the signal light only requires the external drive component to rotate the drive screw 20 in one direction, making it simple to operate and reliable.

[0064] As a further invention of this invention, the switching device includes a first spring 16 disposed between the side wall of the base 2 connecting the drive screw 26 and the drive gear 20. The switching device also includes an adjusting wheel 29 fixedly connected to the drive gear 20 and sleeved with the drive screw 26, and a rotating shaft 34-5 rotatably connected to the base 2 via a bearing seat 13. A drive frame 34 is fixedly disposed on the rotating shaft 34-5. The drive frame 34 includes a first shift fork 34-4 and a second shift fork 34-2. The first shift fork 34-4 and the second shift fork 34-2 are connected by a third telescopic rod 34-1. The third telescopic rod 34-1 is slidably connected to the first shift fork 34-4; the telescopic connecting sleeve is rotatably connected to the second shift fork 34-2, and the lower end of the second shift fork 34-2 is vertically slidably connected to the base 2 via the second shift fork 34-3; the upper end of the second shift fork 34-2 has a guide surface to facilitate the adjustment wheel 29 to move laterally when the second shift fork 34-2 moves vertically; the switching device also includes a moving shaft 35 connected between the two moving blocks 33, the reciprocating motion of the moving shaft 35 can drive the first shift fork 34-4 to reciprocate around the axis of the bearing seat 13, the active... A prism section is located on the lead screw 26, and it is slidably connected to the driving gear 20 through the prism. This prevents the driving gear 20 from rotating continuously with the lead screw 26. The engagement between the prism and the driving gear 20 allows the lead screw 26 to drive the driving gear 20 only for a limited time. When the driving gear 20 disengages from the lead screw, the lead screw 26 can no longer drive the driving gear 20 to rotate. In other words, the driven gear 15 and the moving component cease to move. Such a switching between the moving component and the fixed mechanism is necessary when switching their motion states. The connection between the driving gear 20 and the lead screw 26 facilitates this switching. The switching method utilizes the meshing between the driving gear 20 and the driven gear 17 for more stable switching, because the meshing switching between two gears can easily cause tooth collisions. However, by using the cooperation of prisms and grooves, the switching process can be made smoother by changing the shape of the prism or chamfering. Moreover, the prism is not a precision part, so the maintenance and cost are lower. The switching device also includes a sleeve 30-1 with one end fixed to the drive block 30 and sleeved on the driving screw 26. The sleeve 30-1 is used to drive the driving gear 20 to slide into the driving screw 26 when the drive block 30 is about to disengage from the threaded connection with the driving screw 26.

[0065] As a power switching device for a moving component and a fixed mechanism, since both parts are driven by the same drive device, a power switching device was invented to solve the above-mentioned problem in order to prevent the moving component and the fixed mechanism from interfering with each other during operation.

[0066] In use: When the driving force drives the drive screw 26, the drive screw 26 transmits power to the driven screw 15 through the drive gear 20 and the driven gear 17. The driven screw 15 causes the moving block 33 to move relative to the drive screw 33. The moving block 33 is fixedly connected to the moving shaft 35. The movement of the moving block 33 causes the moving shaft 35 to drive the first shift fork 34-4, causing the drive frame 34 to rotate around the rotating shaft 34-5. The rotation of the first shift fork 34-4 around the rotating shaft 34-5 causes the second shift fork 34-2 to move downward through the third telescopic rod 34-1, thereby freeing it from the restriction of the adjusting wheel 29 (the adjusting wheel 29 is fixedly connected to the drive gear 20). Next, the function of adjusting wheels 29 and 34-2 is to enable the drive gear 20 to overcome the thrust greater than the spring and remain stable, and the gear teeth of the drive gear 20 will not wear. Furthermore, under the action of the first spring 16, the drive gear 20 moves to the left and abuts against the sleeve 30-1. Further, through the sleeve 30-1, the drive block overcomes the elastic force of the second spring 14 and abuts against the threaded section on the drive screw 26 (it should be noted that at this time the drive gear 20 has not completely disengaged from the drive screw 26. Before this, the drive screw 26 cannot drive the drive block 30 to move).

[0067] The drive screw 26 continues to rotate, driving the drive block 30 to move. As the drive block 30 moves, the first spring 16 continues to push the drive gear 20 to slide relative to the drive screw 26 until the prism section of the drive screw 26 disengages from the drive gear 20. After this, the drive gear 20 stops moving until the drive block 30 returns. Once the drive block 30 has disengaged from the threaded section of the drive screw 26, it stops driving the drive screw 26 to rotate. At this time, the second spring 14 is in a charged state. When it is necessary to release the fixation, the drive component can be reversed. All reverse motion processes are the reverse of the above process and will not be described in detail here.

[0068] In fact, this switching device has a simple structure, high compatibility, and low requirements for mating components. It avoids complex state switching between many parts and eliminates the risk of gear collisions, making it safe and reliable. Furthermore, this switching device does not cause equipment damage due to excessive rotation during the support and fixing process. When the number of rotations exceeds the actual stroke, it will only idle. In practice, simply adding a spring between the drive block 30 and the third stop block, and setting the drive screw 26 to not be in close contact with the third stop block, is sufficient to ensure that the overall equipment does not have the risk of excessive rotation, making the equipment more stable and reliable.

[0069] Working principle: Assuming the roller 3 is initially extended, the power unit is inserted into slot 2-1, and the drive screw 26 is rotated, driving the drive gear 20. The drive gear 20 meshes with the driven gear 17, and the power is transmitted to the driven screw 15 through the driven gear 17. Since the moving block 33 is slidably connected to the base 2, the driven screw 15 rotates, causing the two moving blocks 33 on one side to move simultaneously and relative to each other. The moving block 33 drives the first telescopic rod 25 through the first connecting rod 28, causing the roller 3 to retract. This setting can eliminate the instability caused by the roller 3 to the equipment. During the movement of the moving block 33, the two moving blocks 33 near the drive gear 20 are fixedly connected to the moving shaft 35. When the moving block 33 moves, it drives the moving shaft 35 to move simultaneously. There is a first shift fork 34-4 in the radial direction of the moving shaft 35. When the moving shaft 35 drives the first shift fork 34-4, it causes the drive frame 34 to rotate around the rotating shaft 34-5, causing the second shift fork 34-2 to move downward. At this time, the adjusting wheel 29 (fixedly connected to the drive gear 20) is not restricted by the second shift fork 34-2 and under the action of the first spring 16, the power of the drive screw 26 and the drive gear 20 is interrupted (the drive screw and the drive gear 20 are connected by a spline). Under the action of the first spring 16, the adjusting wheel 29 pushes the drive block 30 to engage with the drive screw 26. The drive block 30 continues to move. During this movement, the trigger block 24-1 at the end of the fifth telescopic rod 24-2 moves axially together with the first stop block 21 (fixedly connected to the piston rod) until the trigger block 24-1 reaches the second stop block 23. The second stop block 23 shortens the fifth telescopic rod 24-2 until it disengages from the first stop block 21. Pushing the first stop block 21 drives the piston to move. When the trigger block 24-1 touches the second stop block 23, one cleaning cycle is completed. When the first stop block 21 completely disengages from the trigger block 24-1, the cleaning device returns to its starting state under the action of the fourth spring 38 and the fifth spring 39. This process allows the suction cup 27 to adhere better to the ground, increasing the stability of the equipment. At this time, the drive block 30 continues to move. When it passes the second stop block 23, the fifth telescopic rod 24-2 returns to its original state under the action of the springs. During the continuous movement of the drive block 30, power is transmitted to the first fixed block 12 via the second connecting rod 9, causing both ends of the second telescopic rod 11 to extend, allowing the suction cup 27 to adhere to the surface being cleaned. Simultaneously, the upper end of the second telescopic rod 11 pushes the limiting cylinder 7 upward, causing the semi-cylindrical cylinder 4 to rotate around the bracket 6 until it forms a 90-degree angle with the upper surface of the base 2. This structure reduces space usage during transportation.

[0070] When roller 3 needs to be lowered, the drive device is rotated in the reverse direction, causing drive block 30 to move closer to drive gear 20. This retracts the telescopic rod via the second connecting rod 9, raising suction cup 27 and retracting signal light assembly 1. When the fifth telescopic rod 24-2, under the action of the second stop 23 and torsion spring 24, triggers the block to rotate unidirectionally around torsion spring 24, passing the second stop 23. As drive block 30 continues to move, it pushes adjusting wheel 29, causing drive gear 20 and lead screw to reconnect via splines, disengaging drive block 30 from the lead screw thread. When drive gear 20 drives driven gear 17 to rotate, moving block 33 moves towards driven gear 17. Moving block 33 drives first shift fork 34-4 to rotate, causing second shift fork 34-2 to move upwards, re-limiting the axial movement of adjusting wheel 29. Simultaneously, moving block 33 pushes first telescopic rod 25 via first connecting rod 28, causing roller 3 to extend from base 2 and be in a movable state.
