Description

Technical Field

[0001] The present invention relates to the technical field of working platforms, and particularly to a working platform with strong adaptability. Background Art

[0002] When processing large workpieces, a working platform is needed to drive construction workers to adjust their heights, so as to facilitate raising the height of construction workers and thus process different positions of the workpiece. However, general working platforms have some disadvantages when in use, such as: When a general working platform is in use, the flatness of each position of the device cannot be accurately adjusted. As a result, when the device is in use, as the working platform rises, the center of gravity moves upward and the device will become unstable, which is not conducive to the device being used in different positions, making the adaptability of the device poor, and further being not conducive to the use of the device. Summary of the Invention

[0003] The purpose of the present invention is to provide a working platform with strong adaptability to solve the problems raised in the above background art.

[0004] A working platform with strong adaptability includes a base and a support platform: on both sides of the center of the upper end of the base, height adjusting mechanisms are symmetrically arranged, the height adjusting mechanisms penetrate through the support platform, limit columns for positioning the support platform are arranged on the upper end of the base, an anti-falling mechanism is arranged inside the support platform, and an adaptive adjusting mechanism is arranged on the side of the base.

[0005] When the device is in use, the adaptive adjusting mechanism is used to increase the stability of the base during use, and then the height adjusting mechanism is used to adjust the height of the support platform, so as to adjust the height of the support platform. The user can stand on the surface of the support platform, thus lifting the construction workers to different heights, facilitating the construction workers to carry out operations. When the support platform moves up and down, the limit columns will limit the support platform, thereby increasing the stability of the support platform during movement.

[0006] Preferably, the adaptive adjusting mechanism includes an electric push rod, a support leg, a fixing groove, a positioning rod and a return spring. The electric push rod is arranged on the side of the base, the lower end extending end of the electric push rod is provided with a support leg, fixing grooves are equiangularly opened at the bottom end of the support leg, a positioning rod is slidably arranged inside the fixing groove, and a return spring is arranged on the outer side of the positioning rod, and the return spring is located inside the fixing groove.

[0007] The bottom of the base is provided with rollers, which facilitates the adjustment of the position of the base. When the device is in use, the support legs are driven to move downward by the electric push rod to support the base. When the support legs contact the ground, the positioning rod is pushed upward to move. Thus, the inclination angle inside the support legs can be reflected according to the length of the positioning rod extending out of the fixed slot at different positions, and accordingly, the relative positions between the support legs and the electric push rod can be adjusted, so that the device can be used at different positions. When the positioning rod is no longer in contact with the ground, the return spring drives the positioning rod to return to its original position.

[0008] Preferably, a pressure sensor is provided above the inside of the fixed slot, and the bottom of the positioning rod has elasticity.

[0009] After the positioning rod is in full contact with the ground, the positioning rod is squeezed into the inside of the support leg. At this time, the positioning rod is in a compressed state, and at the same time, the positioning rod contacts the pressure sensor, so that the contact state between the positioning rod and the ground is reflected through the pressure sensor. Based on this, the relative distance between the electric push rod and the support leg is automatically adjusted, so that most of the positioning rods are retracted into the inside of the support leg, ensuring the stability of the support leg during use.

[0010] Preferably, the height adjustment mechanism includes a support column, rollers, a steel wire rope and a winding mechanism. The support column penetrates the support platform, the bottom of the support column is connected to the base, a roller is rotatably provided inside the upper end of the support column, one end of the steel wire rope is connected to the support platform, the side of the steel wire rope is attached to the upper end of the roller, and the other end of the steel wire rope is connected to a winding mechanism, and the winding mechanism is provided at the upper end of the base.

[0011] When the device is in use, the winding mechanism drives the steel wire rope to move, and the roller guides the steel wire rope, and the support column supports the roller, so as to control the height of the support platform as the steel wire rope is wound, so as to process materials at different heights.

[0012] Preferably, the winding mechanism includes a fixed frame, a motor, a wire reel and a speed reduction mechanism. The fixed frame is provided at the upper end of the base, a speed reduction mechanism is provided on the side of the fixed frame, one end of the speed reduction mechanism is connected to the motor, the output end of the speed reduction mechanism is connected to the wire reel, the steel wire rope is wound around the outside of the wire reel, and a guide wheel is provided on the outside of the support column.

[0013] When the device is in use, the motor drives the speed reduction mechanism to rotate, and the speed reduction mechanism amplifies the force, thereby increasing the torque of the wire reel, facilitating the winding of the steel wire rope, and further facilitating the adjustment of the height of the support platform. The guide wheel can guide the steel wire rope to facilitate the contact between the steel wire rope and the wire reel.

[0014] Preferably, the speed reduction mechanism includes a connecting frame, a sun gear, a planetary gear, a coupling sleeve and a fixed disk. The connecting frame is arranged on the side of the fixed frame, and the other side of the connecting frame is connected with a motor. The sun gear, the planetary gear, the coupling sleeve and the fixed disk are located inside the connecting frame, and the motor is located outside the connecting frame. The output end of the motor is connected with the sun gear, the outside of the sun gear is meshed with the planetary gear, the outside of the planetary gear is meshed with the coupling sleeve, the coupling sleeve is rotatably arranged inside the connecting frame, the side of the planetary gear is rotatably provided with the fixed disk, and the side of the fixed disk is connected with the wire take-up reel.

[0015] When the device is in use, the motor will drive the sun gear to rotate. When the sun gear rotates, it will drive the planetary gear to move around the sun gear. As the planetary gear moves, it will drive the rotation of the fixed disk and the wire take-up reel, so as to reduce the rotation speed of the wire take-up reel, increase the torque of the wire take-up reel, and improve the effect of the device in winding the steel wire rope.

[0016] Preferably, the anti-falling mechanism includes a fixed shaft, a fixed column, a connecting column, a support spring, a locking rod and a torsion spring. The fixed shaft is rotatably arranged inside the support platform, a torsion spring is connected to the outside of the fixed shaft, the other end of the torsion spring is connected with the support platform, the fixed column and the locking rod are respectively arranged on the outside of the fixed shaft, the connecting column is slidably arranged on the outside of the fixed column, and a support spring is arranged inside the connecting column.

[0017] When the device is in use, since the torsion spring will drive the fixed shaft to rotate, the fixed column and the connecting column will always contact the support column. When the support platform descends slowly, due to the limited rotation angle of the fixed shaft, the locking rod will not contact the support column. When the device falls, the locking rod contacts the support column, so as to increase the resistance when the support platform moves downward, thus avoiding the phenomenon of the device falling. When the connecting column contacts the support column, the connecting column and the fixed column will slide, and the support spring will drive the connecting column to return to its original position.

[0018] Preferably, extension platforms are arranged on both sides of the support platform.

[0019] The extension platforms can increase the area of the support platform, which is convenient for construction. The extension platforms are slidably arranged inside the support platform and are fixed by bolts between them. Therefore, the overall area of the equipment platform can be adjusted according to needs, and then the use of the equipment is facilitated.

[0020] The beneficial effects of the present invention are: 1. When the device is in use, the motor drives the reduction mechanism to rotate, thereby adjusting the position of the wire rope and further adjusting the height of the support platform. During the adjustment process, when the support platform moves downward too fast, the rotation speed of the fixed shaft and the connecting column will also increase, causing the locking rod to get stuck with the support column, thus preventing the support platform from falling. 2. When the device is in use, the pressure sensor is used to detect the pressure conditions on the positioning rods at different positions of the support legs, so as to reflect the flatness of the support legs, ensuring that the support legs are flat and enabling the device to automatically adapt to the environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] In specific implementation: As Figures 1-6 shown, an operation platform with strong adaptability includes a base 1 and a support platform 13: on both sides of the center of the upper end of the base 1, height adjustment mechanisms are symmetrically arranged, the height adjustment mechanisms penetrate through the support platform 13, a limiting column 27 for positioning the support platform 13 is arranged on the upper end of the base 1, an anti-falling mechanism is arranged inside the support platform 13, and an adaptive adjustment mechanism is arranged on the side of the base 1.

[0025] When the device is in use, the adaptive adjustment mechanism is used to increase the stability of the base 1 during use, and then the height adjustment mechanism is used to adjust the height of the support platform 13, so as to adjust the height of the support platform 13, and the user can stand on the surface of the support platform 13, thereby lifting the construction personnel to different heights, facilitating the construction personnel to carry out operations. When the support platform 13 moves up and down, the limiting column 27 will limit the support platform 13, thereby increasing the stability of the support platform 13 during movement.

[0026] The adaptive adjustment mechanism includes an electric push rod 21, a support leg 22, a fixed groove 23, a positioning rod 24 and a return spring 25. The electric push rod 21 is arranged on the side of the base 1. The lower end extending end of the electric push rod 21 is provided with a support leg 22. Fixed grooves 23 are equally angled and opened at the bottom end of the support leg 22. A positioning rod 24 is slidably arranged inside the fixed groove 23. A return spring 25 is arranged on the outer side of the positioning rod 24, and the return spring 25 is located inside the fixed groove 23.

[0027] Rollers are arranged at the bottom of the base 1, so as to facilitate the adjustment of the position of the base 1. When the device is in use, the electric push rod 21 is used to drive the support leg 22 to move downward, so as to support the base 1. When the support leg 22 contacts the ground, it will push the positioning rod 24 to move upward. Thus, according to the length of the positioning rod 24 extending out of the fixed groove 23 at different positions, the inclination angle inside the support leg 22 can be reflected, and accordingly, the relative positions between the respective support legs 22 and the electric push rod 21 can be adjusted, so that the device can be used at different positions. When the positioning rod 24 is no longer in contact with the ground, the return spring 25 will drive the positioning rod 24 to return to its original position.

[0028] A pressure sensor 26 is arranged above the inside of the fixed groove 23, and the bottom of the positioning rod 24 has elasticity.

[0029] After the positioning rod 24 is in full contact with the ground, the positioning rod 24 will be squeezed into the interior of the support leg 22. At this time, the positioning rod 24 is in a compressed state. At the same time, the positioning rod 24 will contact the pressure sensor 26, so as to reflect the contact state between the positioning rod 24 and the ground through the pressure sensor 26. Based on this, the relative distance between the electric push rod 21 and the support leg 22 is automatically adjusted, so that most of the positioning rods 24 are retracted into the interior of the support leg 22, ensuring the stability of the support leg 22 during use.

[0030] The height adjustment mechanism includes a support column 2, a roller 3, a steel wire rope 12 and a winding mechanism. The support column 2 penetrates the support platform 13. The bottom of the support column 2 is connected to the base 1. A roller 3 is rotatably arranged inside the upper end of the support column 2. One end of the steel wire rope 12 is connected to the support platform 13. The side of the steel wire rope 12 is attached to the upper end of the roller 3. The other end of the steel wire rope 12 is connected to a winding mechanism, and the winding mechanism is arranged at the upper end of the base 1.

[0031] When the device is in use, the winding mechanism is used to drive the steel wire rope 12 to move, and the roller 3 guides the steel wire rope 12, and the support column 2 supports the roller 3, so as to control the height of the support platform 13 as the steel wire rope 12 is wound, so as to process materials at different heights.

[0032] The winding mechanism includes a fixed frame 4, a motor 6, a wire reel 11 and a speed reduction mechanism. The fixed frame 4 is arranged at the upper end of the base 1. A speed reduction mechanism is arranged on the side of the fixed frame 4. One end of the speed reduction mechanism is connected to the motor 6, and the output end of the speed reduction mechanism is connected to the wire reel 11. The steel wire rope 12 is wound around the outside of the wire reel 11. A guide wheel 28 is arranged on the outside of the support column 2.

[0033] When the device is in use, the motor 6 drives the speed reduction mechanism to rotate. The speed reduction mechanism amplifies the force, thereby increasing the torque of the wire reel 11, facilitating the winding of the steel wire rope 12, and further facilitating the adjustment of the height of the support platform 13. The guide wheel 28 can guide the steel wire rope 12 to facilitate the contact between the steel wire rope 12 and the wire reel 11.

[0034] The speed reduction mechanism includes a connecting frame 5, a sun gear 7, a planetary gear 8, a clutch sleeve 9 and a fixed disk 10. The connecting frame 5 is arranged on the side of the fixed frame 4. The other side of the connecting frame 5 is connected to the motor 6. The sun gear 7, the planetary gear 8, the clutch sleeve 9 and the fixed disk 10 are located inside the connecting frame 5. The motor 6 is located outside the connecting frame 5. The output end of the motor 6 is connected to the sun gear 7. The outside of the sun gear 7 is meshed with the planetary gear 8. The outside of the planetary gear 8 is meshed with the clutch sleeve 9. The clutch sleeve 9 is rotatably arranged inside the connecting frame 5. The side of the planetary gear 8 is rotatably arranged with the fixed disk 10. The side of the fixed disk 10 is connected to the wire reel 11.

[0035] When the device is in use, the motor 6 drives the sun gear 7 to rotate. When the sun gear 7 rotates, it drives the planetary gear 8 to move around the sun gear 7. As the planetary gear 8 moves, it drives the rotation of the fixed disk 10 and the wire reel 11, thereby reducing the rotation speed of the wire reel 11 and increasing the torque of the wire reel 11, improving the effect of the device in winding the steel wire rope 12.

[0036] The anti-falling mechanism includes a fixed shaft 15, a fixed column 16, a connecting column 17, a support spring 18, a locking rod 19 and a torsion spring 20. The fixed shaft 15 is rotatably arranged inside the support platform 13. A torsion spring 20 is connected to the outside of the fixed shaft 15, and the other end of the torsion spring 20 is connected to the support platform 13. The fixed column 16 and the locking rod 19 are respectively arranged on the outside of the fixed shaft 15. The connecting column 17 is slidably arranged on the outside of the fixed column 16, and a support spring 18 is arranged inside the connecting column 17.

[0037] When the device is in use, since the torsion spring 20 drives the fixed shaft 15 to rotate, the fixed column 16 and the connecting column 17 will always be in contact with the support column 2. Therefore, when the support platform 13 slowly descends, due to the limited rotation angle of the fixed shaft 15, the locking rod 19 will not contact the support column 2. When the device falls, the locking rod 19 contacts the support column 2, thereby increasing the resistance when the support platform 13 moves downward, thus preventing the device from falling. When the connecting column 17 contacts the support column 2, the connecting column 17 will slide relative to the fixed column 16, and the support spring 18 will drive the connecting column 17 to return to its original position.

[0038] Extension platforms 14 are arranged on both sides of the support platform 13.

[0039] The extension platforms 14 can increase the area of the support platform 13, facilitating construction. The extension platforms 14 are slidably arranged inside the support platform 13 and are fixed to each other by bolts. Therefore, the overall area of the equipment platform can be adjusted according to requirements, thereby facilitating the use of the equipment.
