Description

Technical Field

[0001] The present invention relates to the technical field of brackets, and specifically to an adjustable steel structure bracket. Background Art

[0002] A "bracket" is also called a "scaffold", which was originally a term in the construction industry, specifically referring to a temporary support erected when building a building. This support will be removed after the building is completed. However, brackets are now extremely widely used and can be seen everywhere in work and life, such as the tripod of a camera and the heart stent used in the medical field.

[0003] When carrying out interior decoration of a house, scaffolds or folding ladders are usually used for support. When constructing at a high position on the wall, it is necessary to frequently change the construction position along the wall. However, when moving and changing the construction position each time, general scaffolds and folding ladders need to be taken down or descended for movement, which requires construction workers to frequently go up and down. Therefore, an adjustable steel structure bracket is needed, so that the overall device can be manually controlled to move along a straight line on the surface of its construction platform, facilitating construction at a high position on the wall without the need for construction workers to frequently go up and down when frequently adjusting the construction position along the wall, ensuring the convenience of construction workers.

The transmission mechanism controls the overall linear movement of the device along the guide rail mechanism, facilitating construction on high walls. When the construction position needs to be frequently adjusted along the wall, construction workers do not need to frequently go up and down, ensuring the convenience of construction workers.

[0017] 2. The adjustable steel structure support, through the guide rail frame, anti-slip plate, anti-slip waist hole, splicing opening, storage opening, folding clamping block and guide rail, can form a guide for the linear movement of the device at the bottom of the device, preventing the device from deviating or tilting outward when moving along the wall, ensuring the smoothness of the device operation route, and avoiding large bumps when the device runs on the uneven un-decorated ground indoors.

[0018] 3. The adjustable steel structure support, through the bottom plate, upper extension plate, lower extension plate, first rotating shaft, first transmission wheel, second rotating shaft, guide wheel and crank, enables construction workers to control the linear movement and direction of the device by turning the crank on the surface of the grid platform, ensuring the integrity of the parts of the transmission mechanism.

[0019] 4. The adjustable steel structure support, through the third rotating shaft, large transmission wheel, second transmission wheel, third transmission wheel, first transmission belt and second transmission belt, can transmit the power and direction control provided by the crank to the second round shaft, and achieve torque amplification and labor saving through the groove diameter difference between the large transmission wheel and the first transmission wheel.

[0020] 5. The adjustable steel structure support, through the inner wheel block, pin column, limiting edge and limiting groove, provides internal support for the outer wheel ring, ensures the strength of the outer wheel ring, and facilitates the disassembly, installation and replacement of the outer wheel ring.

[0021] 6. The adjustable steel structure support, through the outer wheel ring, limiting ridge and guide groove, can cooperate with the guide rail to ensure that the outer wheel ring rolls linearly along the guide rail, ensuring the stable operation of the device on the surface of the guide rail.

[0022] 7. The adjustable steel structure support, through the fixed brake disc, slide rail, threaded column, slider, push-pull handle, connecting plate, moving brake disc, anti-slip pad, anti-slip teeth, compression spring and chute, enables the braking and locking and unlocking of the roller mechanism on the surface of the second round shaft to be achieved by pushing and pulling the push-pull handle on the surface of the grid platform, facilitating the locking of the device after it runs to the working position.

[0023] 8. The adjustable steel structure support, through the inclined frame, extension plate, rubber pad and connecting block provided, facilitates using extension plates of different heights as temporary workstations to construct the low-lying wall surface, and conveniently uses the inclined frame as an up-and-down ladder to assist construction workers in going up and down.

[0024] 9. The adjustable steel structure support, through the fourth rotating shaft, guardrail, protective net plate, holding hole and buffer block provided, facilitates forming a protection around construction workers through the guardrail during construction, improves construction safety, and can lift the obstruction by folding the guardrail when constructing the wall surface on the side of the guardrail.

[0025] 10. The adjustable steel structure support, through the side frame, platform frame, bottom cross frame and inclined frame provided, facilitates enclosing into a right trapezoid structure to ensure the stable use of the inclined standing platform structure, and can also ensure that the device can move to the end of the wall surface, reducing the generation of work area dead corners.

By providing the side frame 1, the platform frame 2, the bottom cross frame 3, and the inclined frame 1401, it is convenient to enclose a right trapezoidal structure to ensure the stable use of the inclined standing platform structure, and at the same time, it can also ensure that the device can move to the end of the wall, reducing the generation of dead corners in the working positions.

[0046] Working principle: When in use, first place the guide rail frame 1001 at an appropriate position on the ground below the wall to be constructed, making the guide rail frame 1001 parallel to the wall. Open the folding latch 1006, and through the folding latch 1006 being inserted into the splicing interface 1004 of the adjacent guide rail frame 1001, multiple guide rail frames 1001 are connected end to end. Then, move the device onto the surface of the guide rail frame 1001, making the guide rail 1007 inserted into the guide groove 1207. The construction worker reaches above the grid platform 6 through the extension plate 1402 to work. When the device needs to be moved, first pull the push-pull handle 1305. The push-pull handle 1305 drives the threaded column 1303 to rotate. The threaded column 1303 pushes the slider 1304 to slide outwards through the thread, separating the moving brake disc 1307 from the fixed brake disc 1301 to achieve unlocking. Then, turn the crank 1108. The crank 1108 drives the first transmission wheel 1105 to rotate through the first rotating shaft 1104. The first transmission wheel 1105 drives the large transmission wheel 1110 to rotate through the first transmission belt 1113. The large transmission wheel 1110 drives the second transmission wheel 1111 to rotate through the third rotating shaft 1109 and achieves torque amplification. The second transmission wheel 1111 drives the third transmission wheel 1112 to rotate through the second transmission belt 1114. The third transmission wheel 1112 drives the roller mechanism to roll along the guide rail 1007 through the second rotating shaft 9, thereby realizing the movement of the device. When the device moves to an appropriate position, push the push-pull handle 1305. The push-pull handle 1305 drives the threaded column 1303 to rotate in the reverse direction. The threaded column 1303 pushes the slider 1304 to slide inwards through the thread, making the moving brake disc 1307 move towards the fixed brake disc 1301 and finally stick tightly, thereby realizing the locking of the roller mechanism.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
