The construction field generally needs to bear constructors or building equipment to a to-be-constructed area by means of a construction platform, in order to improve the utilization rate, the existing construction platform is generally designed with larger size to bear more constructors or building equipment, when, for example, a narrow space which only allows one person to enter and exit or a special-shaped structure which needs to adjust the construction direction in real time occurs, the construction platform cannot be further close to the narrow space or the special-shaped structure, and only can rely on the constructors to outwards extend out of the body to operate or be bound through safety ropes to operate, so that the defects of inconvenience in operation and easiness in occurrence of safety accidents are overcome.
In view of this, the present invention provides a novel aluminum alloy mobile construction platform, and fig. 1 to 6 are an embodiment of the novel aluminum alloy mobile construction platform provided by the present invention, and the novel aluminum alloy mobile construction platform is described below with reference to specific drawings.
Referring to fig. 1, in this embodiment, the novel aluminum alloy mobile construction platform is suitable for building construction, and can be used for bearing constructors or building equipment, and of course, the novel aluminum alloy mobile construction platform is also suitable for other fields requiring bearing constructors or equipment, which is not limited herein. The novel aluminum alloy movable construction platform is used for bearing constructors to explain construction of a region to be constructed by taking the construction of the region to be constructed as an example. The novel aluminum alloy movable construction platform comprises a frame body 1, a standing platform 2, an adjusting platform 3 and a driving device 4, wherein the frame body 1, the standing platform 2 and the adjusting platform 3 can be made of aluminum materials, and the novel aluminum alloy movable construction platform has enough supporting strength. The standing platform 2 may be movably mounted to the frame 1 directly, or may be indirectly mounted to the frame 1, for example, through a safety rope, where the standing platform 2 may be fed to the first area along a feeding direction, and the feeding of the standing platform 2 generally needs to be driven by a power structure, where the power structure may be, for example, a hydraulic cylinder or a driving motor and a gear set transmission system, and the feeding direction may be, for example, a movement along a lateral direction and/or an up-down direction, and the mounting of the power structure and the standing platform 2 may refer to the prior art, which is not described herein in detail. The adjusting platform 3 is movably arranged on the standing platform 2 and has a movable travel along the transverse direction and the up-down direction; the driving device 4 is used for driving the standing platform 2 to feed to a second area along the movable travel; wherein the second area is closer to the area to be constructed than the first area. It should be noted that, the size of the standing platform 2 is generally larger than that of the adjusting platform 3, so that the standing platform has enough supporting force and can bear more constructors; the adjusting platform 3 has smaller size, and is more convenient for carrying a small number of constructors to move to a narrow space or continuously change directions along the peripheral outline of the special-shaped structure. Moreover, on the premise of ensuring that the standing platform 2 has enough supporting force, the adjusting platforms 3 can be arranged in a plurality of modes, correspond to a plurality of areas to be constructed, and respectively move designated constructors to the areas to be constructed for construction by fixed points by the adjusting platforms 3, thereby being beneficial to improving the construction operation efficiency.
According to the technical scheme, a plurality of constructors can be transported to the first area close to the area to be constructed through the standing platform 2, and at least one of the constructors can be transported to the second area closer to the area to be constructed through the driving device 4 driving the adjusting platform 3, so that the operation on the area to be constructed is more convenient and safer.
Specifically, referring to fig. 2, in the present embodiment, the driving device 4 includes a driving motor 41, a lifting mechanism, and a transmission mechanism, where the driving motor 41 is disposed on the standing platform 2 and has a power output shaft for providing power for the lifting mechanism and the transmission mechanism; the lifting mechanism is movably arranged on the standing platform 2 along the up-down direction, and is respectively connected with the power output shaft and the adjusting platform 3 in a transmission way so as to drive the adjusting platform 3 to move along the up-down direction under the drive of the driving motor 41; the transmission mechanism is movably arranged on the standing platform 2 along the transverse direction, and is respectively connected with the power output shaft and the adjusting platform 3 in a transmission way so as to drive the adjusting platform 3 to move along the transverse direction under the drive of the driving motor 41. The power output shaft of the driving motor 41 can simultaneously drive and connect the lifting mechanism and the transmission mechanism, so that the adjusting platform 3 can simultaneously perform an upward and downward movable stroke and a transverse movable stroke; or the power output shaft of the driving motor 41 is connected with the lifting mechanism or the transmission mechanism in a clutchable manner, so that only the adjusting platform 3 is driven to move along the upward and downward moving stroke or only the adjusting platform 3 is driven to move along the transverse moving stroke, and the arrangement can enable the movement of the adjusting platform 3 to be more diversified, and is more beneficial to adapting to different construction occasions.
Specifically, referring to fig. 3 and 5, in the present embodiment, the power output shaft of the driving motor 41 extends upward; the lifting mechanism comprises a screw rod 421, a lifting rod 422 and a sleeve 423, wherein the screw rod 421 extends vertically, the lower end of the screw rod 421 is mounted on the power output shaft, and the screw rod 421 can rotate around the shaft under the drive of the power output shaft; the lifting rod 422 is arranged in a step shape with a small upper part and a large lower part so as to form a step surface, and a threaded hole matched with the screw rod 421 is formed at the lower end of the lifting rod 422, so that the lifting rod 422 can move up and down along the drive of the screw rod 421; the sleeve 423 is sleeved at the upper end of the lifting rod 422 and is rotatably arranged relative to the lifting rod 422, the lower end face of the sleeve 423 is abutted to the step face of the lifting rod 422, and the sleeve 423 is in transmission connection with the adjusting platform 3 so as to drive the adjusting platform 3 to move up and down under the driving of the lifting rod 422. When the driving motor 41 rotates at a proper rotation speed, the screw rod 421 and the screw depth of the screw hole are correspondingly changed, so that the lifting rod 422 correspondingly lifts or descends while rotating, and the lower end surface of the sleeve 423 is correspondingly lifted or descends under the abutting of the step surface, but does not rotate, so as to lift or descend the adjusting platform 3.
In addition, referring to fig. 4, in the present embodiment, the transmission mechanism includes a fixed gear 431 and a planetary gear 432, the fixed gear 431 is fixedly mounted on the standing platform 2 along a transverse direction, the driving motor 41 is fixedly mounted on an upper end of the fixed gear 431, and the power output shaft and the fixed gear 431 are coaxially disposed; the planetary gear 432 is meshed with the fixed gear 431, and the planetary gear 432 is respectively connected with the adjusting platform 3 and the power output shaft in a transmission manner, so that the adjusting platform 3 is driven by the driving motor 41 to rotate around the central shaft of the fixed gear 431 in a transverse direction. Specifically, when the driving motor 41 rotates at a suitable rotation speed, the planetary gear 432 is driven by the power output shaft to rotate around the power output shaft, that is, around the central axis of the fixed gear 431, so that the planetary gear 432 is sequentially meshed along the circumferential gear teeth of the fixed gear 431, and then drives the adjustment platform 3 to rotate around the central axis of the fixed gear 431, so that the adjustment platform 3 can rotate transversely to any designated direction and stay. The planetary gears 432 and the fixed gears 431 are configured to allow the rotation of the adjustment platform 3 to be performed along a fixed track and to be more stable than the solution in which the adjustment platform 3 is directly connected to the driving motor 41.
Referring to fig. 2 to 4, in the present embodiment, the driving device 4 further includes a lever assembly, the lever assembly includes a vertical rod 441 and a cross rod 442, the lower end of the vertical rod 441 is mounted to the planetary gear 432 and is coaxially disposed with the planetary gear 432, and the upper end of the vertical rod 441 forms a lever fulcrum; one end of the cross rod 442 is connected with the adjusting platform 3, the middle part is movably mounted on the lever fulcrum, and the other end is mounted on the sleeve 423 or the screw 421. The cross bars 442 and the vertical bars 441 may be arranged to space the distance between the adjusting platform 3 and the standing platform 2, so as to avoid the safety accident caused by the collision between the two due to the interference of the movement of the adjusting platform 3 to the movement of the standing platform 2 or the interference of the movement of the standing platform 2; and, the other end of the cross rod 442 is electrically or manually adjusted to be connected with the sleeve 423 or the screw rod 421, so that the driving motor 41 can drive the adjusting platform 3 to move up and down or rotate transversely in a clutched manner. On this basis, the adjusting platform 3 may be further adjusted, and the adjusting platform 3 is set to be rotatably mounted at one end of the cross rod 442, so that when the cross rod 442 transfers the movement of the sleeve 423 or the screw 421 to the adjusting platform 3, the adjusting platform 3 always ensures that a constructor stands up and down under the action of gravity, so as to improve the safety of the adjusting platform 3, and of course, the adjusting platform 3 may also be provided with a safety handrail to further ensure the construction safety of the constructor.
Further, in this embodiment, the crossbar 442 has a proximal end proximal to the adjustment platform 3 and a distal end distal to the adjustment platform 3; the outer wall of the sleeve 423 is provided with a first electromagnet 423a, the outer wall of the screw rod 421 is provided with a second electromagnet 421a, and the distal end of the cross rod 442 is provided with a magnet 442a matched with the first electromagnet 423a and the second electromagnet 421a, so that the magnet 442a is adsorbed and fixed with the first electromagnet 423a when the first electromagnet 423a is electrified and is adsorbed and fixed with the second electromagnet 421a when the second electromagnet 421a is electrified. When the adjustment platform 3 is required to move up and down, the first electromagnet 423a is operated to be electrified to be adsorbed to the iron sucker 442a, so that under the action of a lever, the lifting movement of the lifting rod 422 can correspondingly realize the descending movement of the adjustment platform 3, and the descending movement of the lifting rod 422 can correspondingly realize the lifting movement of the adjustment platform 3; when the adjustment platform 3 is required to rotate in the transverse direction, the second electromagnet 421a is operated to be electrified to be attracted to the iron attraction member 442a, and the cross rod 442 acts as a connecting rod, so that the rotation of the screw 421 can be transmitted to the adjustment platform 3 through the cross rod 442.
Further, in order to enhance the connection strength between the cross rod 442 and the sleeve 423 and between the cross rod 442 and the screw 421, referring to fig. 2, in this embodiment, a positioning pin 442b is formed on the distal end of the suction member 442 a; a first positioning hole 423b is formed at the position of the first electromagnet 423a corresponding to the positioning pin 442b, so as to limit the relative movement of the cross rod 442 and the sleeve 423 through the plug-in cooperation between the positioning pin 442b and the first positioning hole 423 b; a second positioning hole 421b is formed at the position of the second electromagnet 421a corresponding to the positioning pin 442b, so as to limit the relative movement between the cross rod 442 and the screw rod 421 by the insertion fit between the positioning pin 442b and the second positioning hole 421 b. By means of the arrangement, the adjusting platform 3 can be driven by the lifting mechanism to move up and down only without rotation, and the adjusting platform 3 is driven by the transmission mechanism to rotate only transversely without vertical displacement, so that the stability of the movement of the adjusting platform 3 is improved.
In addition, in the present embodiment, the cross bar 442 is a telescopic bar that is telescopically adjustable in a length direction. By adjusting the extension or retraction of the telescopic rod, the adjusting platform 3 can be correspondingly adjusted to be away from the standing platform 2 or close to the standing platform 2, so as to be suitable for more construction environments.
Referring to fig. 6, in the present embodiment, the lever fulcrum of the vertical rod 441 is in a spherical configuration, the cross rod 442 is provided with a sliding fit groove 442c corresponding to the spherical configuration, and the notch of the sliding fit groove 442c is contracted inwards to form a limiting portion 442d for limiting the spherical configuration from sliding downward. The spherical surface is arranged on the sliding fit groove 442c to slide more smoothly and in multiple directions, so that the lever assembly can be ensured not to generate errors due to interference when transmitting the motions of the lifting mechanism and the transmission mechanism; the limiting portion 442d may effectively prevent the separation of the vertical rod 441 from the cross rod 442, so as to ensure that the connection between the vertical rod 441 and the cross rod 442 is safer and more stable.
Next, in the present embodiment, an elastic buffer member 443 is disposed in the sliding fit groove 442c, and the elastic buffer member 443 is, for example, a rubber pad or a spring, so as to reduce the collision generated by the relative movement between the spherical surface arrangement and the sliding fit groove 442c, reduce the vibration generated to the adjustment platform 3, and improve the service life of the novel aluminum alloy mobile construction platform.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
