Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of building construction equipment, and specifically relates to a low-barycenter screw rod type intelligent lifting work platform. BACKGROUND
[0002] The "protective platform" used in the traditional construction of super high buildings is hung on the upper hanging point of the building, and is connected with the lower hanging point at the bottom of the protective platform near the building side by steel wire rope or electric chain along the building side vertical surface. When the protective platform is lifted, the lower hanging point of the protective platform is forcibly pulled up by the electric hoist, so that the protective platform is lifted to the construction position of the upper layer. This structure can easily cause the protective platform to be overturned when it is forcibly pulled up. The basic structure of this traditional protective platform has two major problems:
[0003] The center of gravity is higher than the lower hanging point - the center of gravity of the protective platform is at the geometric center of the body outside. Because the outer facade must have a protective net, the lower hanging point is at the bottom of the protective platform. The traditional protective platform is easily overturned when it is pulled up by the electric hoist on one side.
[0004] Large moment of force - when the protective platform is pulled up, the horizontal distance between the "over the lower hanging point vertical line" at the force point and the "over the center of gravity vertical line" at the center of gravity of the body itself is more than half of the total width of the cross section of the protective platform. The horizontal distance of the two vertical lines is the force arm of the moment of force of the protective platform. (Force X force arm = moment of force) This moment of force makes the protective platform have a huge tendency to overturn outward. Therefore, the traditional "building construction attached lifting operation safety protective platform" must be provided with strong special guide rails and anti-tilting devices to prevent it from overturning. Due to these two problems, some body falling accidents have occurred in the past 30 years.
[0005] During the construction process of high-rise buildings, the N-1 layer has just been poured with concrete, and the N-2 layer has been poured with concrete about 7 days ago. The strength of the concrete of these two layers cannot meet the requirement of bearing the force of the upper hanging point. Therefore, the N-3 layer of concrete position is selected as the foot base point of the upper hanging point. The size of the electric hoist and the size of the upper and lower hooks occupy the height of one floor, and the body is planned to be lifted by one floor, so the lower hanging point can only be set at the height of N-5 layer. Therefore, the center of gravity of the lifted body is much higher than the lower hanging point of the body itself.
[0006] In addition, the anti-falling device of the conventional protection platform is designed by using the principle of "one-way ratchet" or "one-way wedge". The "one-way" causes the anti-falling device of the protection platform to be effective during the lifting of the frame body, but cannot be used or is invalid during the lowering of the frame body. Because the protection platform cannot be safely lowered, workers can only use the top of the building to directly disassemble and disintegrate the conventional protection platform after the building structure is capped during construction. Before the building facade is decorated, workers have to choose other tools such as a hanging basket as a work platform.
[0007] Therefore, it is particularly important to develop a low-center-of-gravity intelligent lifting work platform with a screw rod. Content of the utility model

[0045] The working platform 4 is arranged outside the bearing frame 5, and a lifting device is arranged between the working platform 4 and the bearing frame 5, so that the working platform 4 and the bearing frame 5 are relatively moved through the lifting device to achieve the purpose of lifting.
[0046] The lifting device is located above the gravity centers of the bearing frame 5 and the working platform 4.
[0047] The lifting device comprises a motor 1 arranged on the working platform 4 and two jack sets 3 arranged on both sides of the motor 1, and a worm 2 is arranged on a through shaft on both sides of the motor 1; the jack set 3 comprises a worm wheel 7, a vertical screw rod 6 is arranged on the worm wheel 7, the top and bottom of the vertical screw rod 6 are connected to two horizontal rods of the bearing frame 5 through bolts respectively, and the worm wheel 7 is engaged with the worm 2.
[0048] The length of the vertical screw rod 6 is not less than the height of the building main body 9.
[0049] The connecting points of the top and bottom of the vertical screw rod 6 to the bearing frame 5 are located above the gravity centers of the bearing frame 5.
[0050] The gravity centers of the bearing frame 5 and the working platform 4 are vertically coincident, and the vertical screw rod 6 is located on the vertical line of the gravity centers of the bearing frame 5 and the working platform 4.
[0051] The bearing frame support 501, the bearing frame root base 502, the bearing frame support wall 503, the working platform support 401, the working platform root base 402 and the working platform support wall 403 are detachably connected to the support structure 10.
[0052] The motor 1 is controlled through a remote control system.
[0053] A protective net 8 is arranged on the outer side of the working platform 4.
[0054] In the frame structure of the bearing frame 5 and the working platform 4, the horizontal rods and the vertical rods are connected through welding or high-strength bolts to enhance the stability and bearing capacity of the structure.
[0055] In the specific implementation, the working platform and the bearing frame are alternately and reliably fixed to the G point (root base point) of the N-3 layer and the Z point (support point) of the N-4 layer of the concrete building. The G point, the Z point and the X point (diagonal support point) form a vertical support triangle GZX. Meanwhile, the GX edges of multiple support triangles GZX are connected by metal profiles to form a stable GXGX plane frame, and the GXGX plane frame provides a safe basis for subsequent lifting work.
[0056] Before the bearing frame is lifted, the working platform is reliably fixed to the building, and the 4-GXGX plane frame of the working platform is erected. Similarly, before the working platform is lifted, the bearing frame is reliably fixed to the building, and the 5-GXGX plane frame of the bearing frame is erected.
[0057] When a certain frame is reliably fixed to the building (for example, Figure 1 the working platform), the frame and the building can be regarded as a mechanical whole. When another frame (for example, Figure 1 the support frame) is lifted, the worm inside the jack set on the upper part of the frame (for example, Figure 1 the working platform) is the mechanical anchor point "M anchor point" of the lifting frame.
[0058] During the lifting of another frame (for example, Figure 1 the support frame), the force point of the lifted frame is at the meshing point of the vertical screw thread and the worm inner circle thread. Moreover, this meshing point (the force point of the support frame) moves along the vertical screw in the length range of the vertical screw.
[0059] With the role exchange between the "lifted frame" and the "fixed frame" between the support frame and the working platform, the "force point" and the "anchor point" are also exchanged. Regardless of the role exchange, the "force point" and the "anchor point" always coincide at the same position, which is above the center of gravity of the lifted frame, that is, the meshing point of the vertical screw thread and the worm inner circle thread.
[0060] From the perspective of mechanics, the invention has two characteristics: Figure 1 、 Figure 2 ):
[0061] A. The center of gravity of the lifted frame is lower than the lifting force point in its own lifting process. The center of gravity of the lifted frame is near its geometric center. The lifting force point of the lifted frame is at the meshing point of the vertical screw thread and the worm inner circle thread.
[0062] B. The horizontal distance between the vertical line passing through the center of gravity of the lifted frame and the vertical line passing through the lifting force point in its own lifting process is very small or tends to zero (gravity X force arm = gravity moment, force arm → zero). This basically eliminates the influence of the gravity moment of the frame during lifting, and reduces the risk of tilting outward during lifting to the minimum.
[0063] The selection of the worm inside the jack set (, Figure 1 、 Figure 2 ) is the structure design of the nut on the vertical screw. This article presents two other characteristics:
[0064] C. The slope principle of the screw and the nut can effectively guide and control the axial movement of the object being guided. Therefore, the combination of the vertical screw and the nut (worm) is the first anti-falling device.
[0065] D. In the worm and worm gear unit, the worm has the function of positive rotation and reverse rotation, while the worm gear can only rotate passively relative to the worm (the worm gear cannot rotate actively relative to the worm). This is the second anti-falling device.
[0066] The difference between the mechanics principle of ( Figure 2 ) and ( Figure 1 ) is that the roles of the "fixed frame" and the "lifted frame" are interchanged between the working platform and the load-bearing frame, resulting in the interchange of the roles of the "anchor point" and the "force point". The rest is the same.
[0067] ( Figure 4 ) is the "low-center-of-gravity screw rod type intelligent lifting working platform" that has completed the work of ascending one floor, and the construction workers can start the construction of the Nth floor.
[0068] Therefore, the working platform of the "low-center-of-gravity screw rod type intelligent lifting working platform" is protected by two anti-falling devices when moving in both ascending and descending directions. In actual application, it can be lifted or lowered at will according to the requirements of the construction process. In particular, after the construction of the concrete structure is completed, the working platform can be lowered layer by layer outside the building by reversing the operation. After the working platform is lowered, stopped, and reliably fixed to a certain position of the building, it can become a construction working platform for decoration or maintenance work. This greatly saves the labor, materials, and time cost of installing a tool platform such as a hanging basket before the decoration workers start the decoration construction.
[0069] A. Working platform component installation position diagram ( Figure 1 ), the outer casing of the motor and the jack unit is reliably fixed to the working platform; the upper and lower ends of the vertical screw rod are reliably fixed to the two beams on the upper part of the load-bearing frame.
[0070] B. The lifting steps of the load-bearing frame are as follows: Figure 1 At this time, the N-1th floor concrete pouring construction has just been completed, and the working platform is being installed for the Nth floor.
[0071] Check that the fixed points of the working platform and the building are reliable and effective. In particular, check the 4G-root points, 4Z-support points, and 4F-wall support points of the working platform. The 4G, 4Z, and 4X-inclined support points form a stable vertical support triangle 4-GZX. Connect the 4-GX edges of multiple groups of 4-GZX in the longitudinal and transverse directions of the plane to form a 4-GXGX plane frame. This plane frame provides a good mechanical foundation platform for the stable lifting of the load-bearing frame.
[0072] Disconnect all connections between the load-bearing frame and the building, leaving only the vertical screw rod male thread and the worm gear internal thread meshing connection, which is flexible and reliable.
[0073] Forward closing electric brake, motor forward transmission, worm drive worm gear forward rotation. Worm gear forward rotation, its inner circle thread to lift the non-rotating vertical screw, vertical screw drive force frame to the last floor. In the reserved position, the force frame and the building are reliably fixed to each other at each reserved position (5G, 5Z, 5F points, and 5X points).
[0074] C. Climbing steps of the working platform:
[0075] Check the wall connection points of the force frame. They must be reliable and effective. In particular, check that the force frame and the building are reliably fixed at 5G-root point, 5Z-support point, and 5F-wall support point. The 5G, 5Z, and 5X-inclined support points form a stable vertical support triangle 5-GZX. Use metal profiles to connect the 5-GX edges of multiple 5-GZX groups in the longitudinal and transverse directions of the plane to form a 5-GXGX plane frame of the force frame. This plane frame provides a good mechanical foundation platform for the stable lifting of the working platform.
[0076] Disconnect all connections between the working platform and the building, leaving only the connection between the worm gear inner circle female thread and the vertical screw male thread, which is flexible and reliable.
[0077] Reverse closing electric brake, motor reverse transmission, worm drive worm gear reverse rotation, reverse worm gear climbs up along the vertical screw through its inner circle thread. The vertical screw is fixed to the force frame, which is already fixed to the building. Therefore, the working platform is raised relative to the building. After the working platform climbs to the reserved position on the last floor, the working platform and the building are reliably fixed at each reserved position (4G, 4Z, 4F points, and 4X points).
[0078] D. The "low center of gravity screw type intelligent lifting working platform" completes the work of lifting one floor:
[0079] The construction workers can start the Nth floor construction work.
[0080] As Figure 5 , (5-1) and (4-1) are before being lifted, and (5-2) and (4-2) are after being lifted.
[0081] Because the jack set is fixed on the working platform, the worm gear works in the jack set, so the position of the worm gear on the working platform does not change at any time.
[0082] The vertical screw is fixed to the upper part of the force frame above its own center of gravity, between the two cross beams.
[0083] When the worm gear rotates forward, the worm gear lifts the vertical screw to drive the force frame to rise.
[0084] When the worm wheel reverses, the worm wheel climbs along the vertical screw upward, and drives the working platform to be lifted.
[0085] Through the overall reverse operation, the low gravity center screw type lifting intelligent working platform is lowered.
[0086] The above describes the utility model and its implementation mode, and this description is not restrictive, and the embodiment shown in the drawings is only one of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired, without departing from the creative purpose of the utility model, without creating a similar structure mode and embodiment to the technical scheme, which should belong to the protection scope of the utility model.
