Description

Technical Field

[0001] This utility model relates to the field of building support equipment technology, specifically to a steel frame support device for preventing falling off during building structure construction. Background Technology

[0002] In construction work, scaffolding is needed for workers to carry out construction work at heights. Traditional scaffolding is mostly made of steel frame structure and is one of the main types of building structure.

[0003] Traditional scaffolding is constructed by splicing together interlocking steel frames. The connection points between the steel frames need to be bound together with straps. Multiple straps work together, making the splicing process quite complex. After assembly, the height is fixed and not adjustable. Furthermore, it needs to be dismantled after use, which is a tedious process and not conducive to storage and relocation. In addition, traditional scaffolding requires the use of ladders when climbing upwards, and the ladders need to be held steady by personnel, which is labor-intensive.

[0004] To address the aforementioned issues, a non-detachable steel frame support device for building structure construction is proposed, which requires no installation and is easy to store. Utility Model Content

[0073] refer to Figures 1 to 7 A steel frame support device for preventing falling off during building structure construction includes a lower base plate 1, an upper top plate 2, a first guard rod 8, a second guard rod 10, a first fixing block 9, a second fixing block 11, a handrail 7, rollers 3, a ladder assembly, a drive mechanism, a lifting mechanism, a flipping mechanism, and a sliding mechanism.

[0074] An upper top plate 2 is movably installed above the lower base plate 1. The upper end of the upper top plate 2 is provided with a first rectangular through hole 201. A ladder assembly is movably installed in the first rectangular through hole 201. The lower base plate 1 is a supporting component when the equipment is raised. The lower base plate 1 has a large contact area with the ground, so it has strong stability.

[0075] The ladder assembly is movably installed between the lower base plate 1 and the upper top plate 2;

[0076] The ladder assembly is driven to flip by a flipping mechanism. The ladder assembly flips upward under the action of the flipping mechanism, and at the same time, the top plate 2 is raised under the action of the lifting mechanism. After the ladder assembly flips upward, it is convenient for construction personnel to enter the top of the raised top plate 2 from the ladder assembly.

[0077] The upper top plate 2 is driven to rise and fall by a lifting mechanism;

[0078] A drive mechanism is installed at the upper end of the lower base plate 1, and the tilting mechanism is driven by the drive mechanism.

[0079] The lifting mechanism is driven by the tilting mechanism.

[0080] Several rollers 3 are movably installed on the outer sides of the left and right side walls of the upper top plate 2. The rollers 3 are detachably and movably installed on the left and right sides of the lower bottom plate 1. When the upper top plate 2 is lowered, the rollers 3 on both sides will support the equipment, making it convenient for the equipment to be moved.

[0081] Handrails 7 are movably installed on the left and right side walls of the top plate 2. The two handrails 7 are movably installed above several rollers 3 that are close to them. When the top plate 2 is lowered, the two handrails 7 will extend backward at the same time, making it convenient for users to hold the handrails 7 and operate the equipment to move with the help of the rollers 3.

[0082] Both handrails 7 are driven to slide by a sliding mechanism;

[0083] The sliding mechanism is driven by the lifting mechanism.

[0084] Several first protective rods 8 are installed at equal intervals on the outer side of the upper end of the first rectangular through hole 201. Several first protective rods 8 are fixedly installed on the upper end of the upper top plate 2. The same first fixing block 9 is fixedly installed on the upper end of several first protective rods 8. Several first protective rods 8 are used to provide certain protection for users who have just climbed into the upper top plate 2 to prevent them from falling off.

[0085] Several second guard rods 10 are installed at equal intervals on the upper end of the top plate 2. The several second guard rods 10 are all installed on one side of several first guard rods 8. The several second guard rods 10 are used to protect the personnel who are working on the top plate 2 and prevent the construction personnel from falling off the top plate 2 during the construction process.

[0086] A second fixing block 11 is fixedly installed on the upper end of each of the second guard rods 10.

[0087] The ladder assembly includes a first link 17, a handrail 18, and a first T-shaped slider 16;

[0088] The first connecting shaft is fixedly installed on the front end of the left and right side walls of the first rectangular through hole 201, and the first end of the first connecting rod 17 is rotatably installed on the outer wall of the two first connecting shafts respectively.

[0089] The upper end of the bottom plate 1 is provided with two first T-shaped slide grooves 103, and the horizontal plates of the first T-shaped sliders 16 are slidably installed in the two first T-shaped slide grooves 103 respectively;

[0090] The vertical plates of the two first T-shaped sliders 16 are slidably connected to the adjacent first T-shaped slide grooves 103, and the second ends of the two first connecting rods 17 are rotatably connected to the adjacent vertical plates of the first T-shaped sliders 16.

[0091] Several handrails 18 are installed at equal intervals between the two first connecting rods 17;

[0092] The first link 17 near the middle of the bottom plate 1 is driven to flip by the flipping mechanism. The two first links 17 and several handrails 18 form a ladder in a conventional form. The two first T-shaped sliders 16 limit the deflection trajectory of the two first links 17, ensuring that the ladder can be stable during the flipping process and in the final flipped state.

[0093] The flipping mechanism includes a second link 22 and a rectangular slider 21;

[0094] The upper end of the lower base plate 1 is provided with a rectangular slide groove 104, which is installed on the right side of the first T-shaped slide groove 103 near the middle of the lower base plate 1.

[0095] A rectangular slider 21 is slidably installed in the rectangular slide groove 104. The upper end of the rectangular slider 21 slides through the rectangular slide groove 104 and is fixedly installed with a first connecting frame. The first end of the second connecting rod 22 is rotatably installed in the first connecting frame.

[0096] A second connecting shaft is fixedly installed on the outer wall of the middle end of the first connecting rod 17 near the middle of the lower base plate 1, and the second end of the second connecting rod 22 is rotatably fitted onto the outer wall of the second connecting shaft.

[0097] The rectangular slider 21 is driven to slide by the driving mechanism;

[0098] The two first links 17 operate through a deflection drive lifting mechanism, as shown in the reference. Figure 6When the rectangular slider 21 is driven by the drive mechanism, it can slide along the rectangular slide groove 104. As the rectangular slider 21 slides, it will drive the second link 22 to start to deflect up and down. During the up and down deflection process, the second link 22 will drive the first link 17 near the middle of the lower base plate 1 to start to deflect up and down. Since the two first links 17 are on the same horizontal plane and the deflection trajectory of the two first links 17 is fixed, the up and down deflection of the second link 22 will ensure the smooth deflection of the two first links 17. It should be noted that in order to ensure that the final flipped state of the two first links 17 is stable, after the second link 22 deflects to be perpendicular to the lower base plate 1, the rectangular slider 21 still needs to slide to the left, and finally make the second link 22 and the first link 17 close to it form a certain angle, thereby increasing the stability of the two first links 17 after stopping.

[0099] The drive mechanism includes a drive motor 14 and a threaded rod;

[0100] The rectangular slider 21 has a threaded rod that passes through its internal thread, and the first end of the threaded rod is rotatably mounted on the front wall of the rectangular slide groove 104.

[0101] A drive motor 14 is installed on the outer side of the rear wall of the lower base plate 1;

[0102] The second end of the threaded rod rotates through the rear wall of the rectangular slide groove 104 and is fixedly connected to the output shaft of the drive motor 14. By starting the drive motor 14, the output shaft of the drive motor 14 starts to rotate and drives the threaded rod fixedly installed on the same axis to start to rotate. The rotation of the threaded rod can drive the rectangular slider 21, which is threaded through it, to start to slide. And because it is a threaded connection, the rectangular slider 21 also has the function of locking in time during the sliding process.

[0103] The lifting mechanism includes a third link 13, a fourth link 12, a second connecting frame 101, a third connecting frame 202, a second T-shaped slider 15, and a third T-shaped slider 19;

[0104] The upper sides of the front wall of the lower base plate 1 are respectively fixedly installed with second connecting frames 101, and the first end of the fourth connecting rod 12 is rotatably installed in the two second connecting frames 101 respectively.

[0105] The upper top plate 2 has two second T-shaped slide grooves 203 on both sides of its lower end. The horizontal plates of the third T-shaped sliders 19 are slidably installed in the two second T-shaped slide grooves 203 respectively. The vertical plates of the two third T-shaped sliders 19 are slidably connected through the second T-shaped slide grooves 203 that are close to them.

[0106] The vertical plates of the two third T-shaped sliders 19 are rotatably connected to the second end of the fourth connecting rod 12 that is close to them;

[0107] Two fourth connecting rods 12 are respectively provided with second rectangular through slots 1201, and third connecting rods 13 are movably installed in the two second rectangular through slots 1201 respectively. The middle ends of the two third connecting rods 13 are respectively rotatably installed in the second rectangular through slots 1201 close to them through third connecting shafts.

[0108] The lower sides of the front wall of the top plate 2 are respectively fixedly installed with third connecting frames 202, and the upper ends of the two third connecting rods 13 are respectively rotatably installed in the third connecting frames 202 that are close to them.

[0109] The upper end of the bottom plate 1 is provided with a third T-shaped slide groove 102 on both sides. The third T-shaped slide groove 102, which is close to the first T-shaped slide groove 103, is installed on the outside of the first T-shaped slide groove 103.

[0110] The cross plates of the second T-shaped sliders 15 are slidably installed in the two third T-shaped slide grooves 102 respectively;

[0111] The vertical plates of the two second T-shaped sliders 15 are respectively slidably connected to the adjacent third T-shaped slide groove 102;

[0112] The lower ends of the two third links 13 are rotatably connected to the vertical plates of the adjacent third T-shaped slide 102, for reference. Figure 6 As the two first links 17 deflect upwards, the two third links 13 also begin to deflect upwards. During this upward deflection, the two second T-shaped sliders 15 begin to slide to the left, and the two third T-shaped sliders 19 simultaneously slide to the left. As the two third links 13 deflect upwards, the adjacent fourth link 12 also begins to deflect upwards. At this point, the angle between the third links 13 and the fourth link 12 decreases, and the upper top plate 2 is naturally lifted, achieving the lifting function. Conversely, when the two first links 17 begin to deflect downwards, the angle between the two third links 13 and the adjacent fourth link 12 will increase. At this time, the upper top plate 2 will descend. As the upper top plate 2 descends, the rollers 3 on both sides will also descend and eventually contact the ground. It should be noted that after the rollers 3 on both sides initially contact the ground, in order to ensure that the lower bottom plate 1 can be supported and lifted off the ground, it is still necessary to control the drive motor 14 to slide the rectangular slider 21 to the right. When the rollers 3 on both sides have completely descended and lifted the lower bottom plate 1, the motor can be turned off.

[0113] The sliding mechanism includes a T-shaped connecting rod 4, a rectangular mounting block 5, an L-shaped sliding rod 6, and a fixed connecting rod 20;

[0114] T-shaped connecting rods 4 are fixedly installed on the outer side walls of the top plate 2 via connectors. The two connectors are fixedly connected to the inner wall of the vertical plate of the T-shaped connecting rod 4 that is close to them.

[0115] Several rollers 3 are rotatably mounted at equal intervals on the outer wall of the crossbar of the T-shaped connecting rod 4 that is close to them;

[0116] Rectangular mounting blocks 5 are fixedly installed on the upper outer walls of the vertical ends of the two T-shaped connecting rods 4 respectively. Rectangular through holes 501 are provided in the two rectangular mounting blocks 5 respectively. Horizontal bars of L-shaped sliding rods 6 are slidably installed through the two rectangular through holes 501 respectively.

[0117] Two handrails 7 are respectively fixedly installed on the front wall of the vertical rod of the L-shaped sliding rod 6 that is close to them;

[0118] A fourth connecting shaft is fixedly installed on the inner wall of the middle end of the two L-shaped slide rods 6, and a fifth connecting shaft is fixedly installed on the outer wall of the vertical plate of the two third T-shaped slide rods 19.

[0119] The same fixed connecting rod 20 is fixedly fitted on the outer wall of the fourth and fifth connecting shafts located on the same side;

[0120] The two fixed connecting rods 20 are detachably in contact with the rear wall of the horizontal plate of the adjacent T-shaped connecting rod 4, as shown in the reference. Figure 5 As the top plate 2 descends, the angle between the two third connecting rods 13 and the fourth connecting rod 14 increases, causing the third T-shaped sliders 19 on both sides to slide to the right. Consequently, the fixed connecting rods 20, which are fixedly installed to the two third T-shaped sliders 19 via the fifth connecting shaft, also begin to slide to the right. The L-shaped sliding rods 6, which are fixedly installed to the two fixed connecting rods 20, can then slide to the right and eventually extend completely to the right as the bottom plate 1 is lifted. At this point, the user can hold the handrails 7, which are fixedly installed on the front wall of the vertical rod of the L-shaped sliding rods 6, and push the equipment to move.

[0121] The implementation method of this utility model:

[0122] When the device is in its initial state, such as Figure 7 As shown in Figure A, the upper top plate 2 is located near the lower bottom plate 1. The ladder assembly is in a nearly horizontal folded state. Several rollers 3 on both sides of the upper top plate 2 are supporting the lower bottom plate 1. The handrails 7 on both sides are also fully extended.

[0123] At this time, the user can hold the handle 7 with both hands and use the rollers 3 on both sides to push the equipment to move. After the equipment is moved to the construction site, start the drive motor 14.

[0124] The output shaft of the drive motor 14 starts to rotate, and during the rotation, the climbing assembly slowly flips and rises. As the climbing assembly flips upward, the top plate 2 also gradually rises. Several rollers 3 on both sides also gradually rise and leave the ground as the top plate 2 rises. After the rollers 3 on both sides leave the ground, the bottom plate 1 begins to support the ground. Since the bottom plate 1 has a large cross-section, it will have a certain degree of stability when in contact with the ground.

[0125] As the ladder assembly continues to flip upwards, the top plate 2 will eventually be fully lifted. The handrails 7 on both sides will slide into the rectangular mounting blocks 5, driven by the adjacent L-shaped sliding rods 6. Once the top plate 2 is fully lifted, the ladder assembly will also flip upwards to its highest point. At this point, the ladder assembly and the bottom plate 1 will be tilted at a certain angle, facilitating effortless climbing for the user. The equipment will then be in its final state as follows: Figure 7 The state shown in B;

[0126] At this point, construction workers can put on safety helmets and climb up the ladder assembly to the top of the upper slab 2 to begin construction work.

[0127] This utility model can flip up the escalator assembly by driving the drive mechanism, which can effectively avoid the need for construction workers to climb to higher places using an additional ladder. As the escalator assembly flips up, the top plate can also be lifted up to meet the construction needs at a certain height. When the top plate is lowered, the rollers on both sides can support the ground, and with the handrails that slide backward, it can help construction workers move and store the escalator.

[0128] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
