Description

Technical Field

[0001] The invention relates to the technical field of decoration design building platforms, in particular to an adjustable decoration design building platform. Background Art

[0002] The decoration construction platform is a lifting equipment designed specifically for the construction and decoration industry. It realizes the lifting or transportation of goods or personnel through a platform that moves up and down. According to different working principles, lifting platforms can be divided into hydraulic, scissor and chain types. It is widely used in interior decoration, exterior wall maintenance, ceiling installation and other scenarios, which greatly improves the efficiency and convenience of decoration work. By using the decoration construction platform, the risk of high-altitude operations can be reduced and the progress of the project can be accelerated. It is an indispensable auxiliary tool in modern decoration projects. The lifting platform not only improves work efficiency, but also enhances the safety of operations.

[0003] Construction platforms are often used during renovation to assist in aerial work.

[0004] The existing patent (publication number: CN115030468B) provides an adjustable indoor decoration construction platform which is not only convenient for operators to go up and down, but also conveniently adjusts the height, so that the operator can conveniently decorate high places and occupies less space. The present invention provides such an adjustable indoor decoration construction platform, including a base, a connecting plate, universal wheels, a support frame, a workbench, a first fixed block, etc. The lower side of the base is connected to a connecting plate, and universal wheels are rotatably provided at the four corners of the lower side of the connecting plate. The upper side of the base is symmetrically connected to a support frame for support. The setting of a ladder can facilitate the operator to go up to the workbench to perform decoration operations. The height of the platform can be conveniently adjusted by driving a hydraulic cylinder, so that it is convenient for operators to decorate higher positions and occupy less space. In the above-mentioned equipment, during the decoration process, the ground may be uneven whether indoors or outdoors, resulting in poor stability when working on the uneven ground, which may cause some wheels to be suspended in the air, thereby reducing the support stability. In addition, the uneven ground will affect the levelness of the decoration building platform and the accuracy of the construction. Especially in decoration work that requires precise alignment and installation, it may cause uneven laying of decoration materials such as tiles and floors, affecting the final decoration effect.

[0005] In view of this, we propose an adjustable decoration design building platform. Summary of the invention

A maintaining spring 5321 is fixedly connected to the outer surface, a brake mounting rod 533 is fixedly connected to the outer surface of the bevel gear mounting seat 51, a driven vertical shaft 54 ​​is fixedly connected to the top surface of the rotating base 52, a cam groove 541 is provided on the outer surface of the driven vertical shaft 54, a hinged base 542 is fixedly connected to the top surface of the driven vertical shaft 54, one end of the hinged base 542 is hingedly connected to an extension rod 5421, the other end of the extension rod 5421 is hingedly connected to a threaded connecting column 5422, a connecting column limiting ring 54221 is fixedly connected to the outer surface of the threaded connecting column 5422, a vertical shaft connecting groove 543 is provided on the inner surface of the driven vertical shaft 54, both ends of the wheel drive shaft 523 are hingedly connected to a universal connecting shaft 55, and the inner surface of the universal connecting shaft 55 An extension connection groove 551 is provided on the surface, an extension spring 552 is fixedly connected to the inner surface of the universal connection shaft 55, an extension connection rod 553 is slidably connected to the inner surface of the extension connection groove 551, the other end of the universal connection shaft 55 is hingedly connected to a driving pulley 56, the outer surface of the driving pulley 56 is sleeved with a connecting belt 561, and the other end of the connecting belt 561 is sleeved with a driving wheel 562 on the inner side. Through the setting of the wheel driving mechanism 5, during use, if the control column 622 is pressed on the surface of the driven vertical shaft 54, then during the descent of the lifting platform 2, the cam contact head 623 cooperates with the cam groove 541 to convert the direct motion into rotation and drive the rotating base 52 to rotate, and the rotating base 52 is rotated through the active bevel gear 521 and the driven bevel gear 522 , driving the wheel drive shaft 523 to rotate, and transmitting the rotation to the universal connecting shafts 55 on both sides. Since the wheel moving column 12 will move up and down, the rotation can be transmitted through the universal connecting shaft 55 regardless of the height difference at both ends, and each universal connecting shaft 55 is divided into two parts, and the middle is connected by an extended connecting rod 553 and an extended spring 552. The two parts of the universal connecting shaft 55 can change the spacing to adapt to the different spacings between the wheel drive shaft 523 and the wheel moving column 12 after movement. The other end of the universal connecting shaft 55 forms a belt transmission in the wheel moving column 12 through a driving pulley 56 and a connecting belt 561, driving the driving wheel 562 to rotate, so that the entire device is driven to move a certain distance when the lifting platform 2 descends. Since the center of gravity drops more steadily during movement,The moving distance can be changed by lowering the height. A brake part is provided on the outer side of the driven vertical shaft 54. When it is not necessary to move, it can be manually locked to prevent the driving wheel 562 from rotating. When the brake matching groove 524 on the rotating base 52 contacts the brake block 53, since the brake block 53 cannot rotate, the rotating base 52 is locked, and the brake block 53 can only move linearly to adjust the release and engage with the brake matching groove 524. When the brake blocks 53 on both sides move away from each other to the limit distance, the angle of the self-locking connecting rod 532 hinged in the middle is a flat angle to form a straight line. At this time, the reverse direction of the restraining force of the short columns 531 installed at both ends by the maintaining spring 5321 is also colinear with the straight line. The angle is zero and the short columns 531 cannot be pulled to make the self-locking connecting rod 532 bend, and the brake blocks 53 maintain the current state of being away from each other. When the rotating base 52 needs to be locked, the self-locking connecting rod 532 is lifted. At this time, the restraining force of the short columns 531 installed at both ends by the maintaining spring 5321 no longer exceeds the rotating center, and the brake blocks 53 on both sides are pulled close to each other to lock the rotating base 52 to maintain the effect. The driven vertical shaft 54 ​​is composed of multiple components to form an integral body to adapt to the different heights required for the lifting platform 2 to rise. The driven vertical shafts 54 are hinged to each other. When the hinged base 542, the extension rod 5421 and the threaded connecting column 5422 are outside, they can be folded and stored in the placement groove 22. When the hinged base 542, the extension rod 5421 and the threaded connecting column 5422 are inside the driven vertical shaft 54, the rotation is blocked by the inner wall of the vertical shaft connecting groove 543, and it cannot rotate to maintain the vertical state, preventing the driven vertical shaft 54 ​​from being too long to affect the use.

[0046] The active bevel gear 521, the driven bevel gear 522 and the wheel drive shaft 523 are all rotatably connected to the bevel gear mounting seat 51. The number of brake blocks 53 is two, and the two brake blocks 53 are symmetrically distributed with the central axis of the brake matching groove 524 as the symmetry axis.

The number of brake mounting rods 533 is two, and the two brake mounting rods 533 are symmetrically distributed with the central axis of the bevel gear mounting seat 51 as the symmetry axis.

Symmetrical distribution, self-locking connecting rods 532 are equidistantly distributed, the maintaining spring 5321 is sleeved on the outer surface of the brake mounting rod 533, and both ends of the maintaining spring 5321 are fixedly connected to the mounting short column 531, the driven vertical shaft 54 ​​is connected to each other, the hinged base 542, the extension rod 5421, the threaded connecting column 5422 and the connecting column limiting ring 54221 are all slidably connected to the inner surface of the vertical shaft connecting groove 543, the threaded connecting column 5422 is threadedly connected to the inner surface of the vertical shaft connecting groove 543, both ends of the extension spring 552 are fixedly connected to the universal connecting shaft 55, and both ends of the extension connecting rod 553 pass through the universal connecting The inner surface of the shaft 55, the driving pulley 56 and the driving wheel 562 are all rotatably connected to the inner surface of the wheel moving column 12, and the driven vertical shaft 54 ​​is slidably connected to the inner surface of the placement groove 22. The brake blocks 53 on both sides can maintain two states of approaching or moving away. When approaching, the rotating base 52 is locked by the brake matching groove 524 to prevent the active bevel gear 521 from driving the wheel driving shaft 523 to rotate, thereby achieving a braking effect. The installation short column 531 is sleeved on the brake installation rod 533 to limit the moving direction and distance, and a maintenance spring 5321 is sleeved to make it also collinear with the self-locking connecting rod 532 when it is collinear. The hinged base 54 2. The extension rod 5421 and the threaded connecting column 5422 can slide freely in the vertical axis connecting groove 543, but the maximum moving distance will be limited by the connecting column limit ring 54221 to prevent detachment. When the threaded connecting column 5422 is threadedly connected to the bottom of the vertical axis connecting groove 543, the rotating connection between the hinge base 542, the extension rod 5421 and the threaded connecting column 5422 is sleeved inside the vertical axis connecting groove 543 to prevent rotation. The extended connecting rod 553 connects the two parts of the universal connecting shaft 55 at both ends by cooperating with the key slot of the extended connecting groove 551, so that the distance between the two parts of the universal connecting shaft 55 can be changed and keep rotating synchronously.
