Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment, in particular to a tool-installable safety lift for house construction. Background Art

[0002] In the field of construction, in order to meet the needs of high-altitude construction, a workbench controlled by a hydraulic system is usually required to support the construction workers in lifting and lowering to meet the needs of high-altitude construction. The traditional lifting mechanism is composed of a walking mechanism, a hydraulic mechanism and an electric control system, and is usually directly equipped and formed in the production workshop.

[0003] Since the traditional lifting equipment composed of a walking mechanism, a hydraulic mechanism and an electric control system is assembled as a complete set, it has excessively high costs and maintenance costs, such as checking the hydraulic system. It is now gradually being replaced by lifts that can be assembled directly on site using tools to save this part of the cost. In the existing technology, in order to meet the needs of construction at heights, only scaffolding is usually used. Although the scaffolding can be installed on site using tools, it does not have a lifting function. The support platform with a lifting function has a very limited construction area, so it is often necessary to move the equipment to change the construction point. During the movement, it relies on the rollers at the bottom of the equipment, which has poor stability and there is a risk of construction workers falling from heights.

[0022] refer to Figures 1 to 10 A tool-installable safety lift for housing construction comprises a first base plate 1, a second base plate 2, a fixed guide rod 4, a first expansion mounting plate 3, a second expansion mounting plate 301, a first protective rod 8, a connecting plate 18, a sliding rod 6, a second protective rod 7, a support frame 9, a flip protective plate 13, a driving mechanism, a flip mechanism, a lifting mechanism, and a sliding mechanism. A second bottom plate 2 is detachably mounted between the two first bottom plates 1. The second bottom plate 2 can be assembled into a whole between the two first bottom plates 1 using tools. A support frame 9 is movably mounted above the two first base plates 1. The two support frames 9 are driven to rise and fall by a lifting mechanism, and the support frames 9 are used to support the user in rising and falling. The front and rear side walls of the two first bottom plates 1 are respectively detachably mounted with fixed guide rods 4, and the two support frames 9 are respectively movably mounted between the two adjacent fixed guide rods 4. The two fixed guide rods 4 are used to mount the n-type mounting brackets 10 described later, and the n-type mounting brackets 10 are used to mount the support frames 9; A connecting plate 18 is fixedly installed between the bottom walls of the two support frames 9. The connecting plate 18 is movably installed above the second bottom plate 2. The connecting plate 18 can move and rise with the support frames 9. The two support frames 9 and one connecting plate 18 greatly expand the construction space for the workers. A flip protection plate 13 is movably mounted on the inner wall of each support frame 9. Both flip protection plates 13 are driven to flip by a flip mechanism. When the two support frames 9 are at the bottom, the two flip protection plates 13 flip downward to provide space for users to enter the support frames 9. As the two N-shaped mounting frames 10 described later continue to slide upward, the flip protection plates 13 gradually flip upward to form a protection between the inner walls of the support frames 9. The lifting mechanism is driven by the flipping mechanism; The first expansion mounting plate 3 and the second expansion mounting plate 301 are fixedly mounted on the front and rear side walls of the second bottom plate 2 respectively through connecting pieces; A plurality of first protection rods 8 are respectively threadedly connected to both sides of the upper end of the first expansion mounting plate 3.

The plurality of second protective rods 7 will slowly unfold as the support frames 9 on both sides rise, providing protection for the front and rear sides of the connecting plate 18. When construction workers stand on the upper end of the connecting plate 18 to carry out construction, they can effectively play a protective role. The four sliding rods 6 are all driven by the sliding mechanism; The connecting plate 18 works by a slide-slide mechanism.

[0023] A plurality of cylindrical guide rods 201 are fixedly mounted on the left and right side walls of the second bottom plate 2; The cylindrical guide rods 201 on the same side are respectively slidably arranged to penetrate between the first bottom plate 1 adjacent thereto; Threaded posts are installed at the outer ends of the cylindrical guide rods 201, and the threaded posts are detachably installed on the outer wall of the first base plate 1 adjacent thereto; The outer walls of several threaded columns are respectively threadedly connected with fixing nuts 20. A temporary assembly can be achieved by aligning and inserting the first base plate 1 on both sides and the several cylindrical guide rods 201 on both sides of the second base plate 2. When the several cylindrical guide rods 201 pass through the first base plate 1 close to them, the threaded columns at the outer ends of the cylindrical guide rods 201 will be exposed. At this time, several matching nuts 20 are threadedly sleeved on the exposed threaded columns to achieve a fastened installation.

[0024] The lower ends of the four fixed guide rods 4 are respectively fixedly mounted with first mounting plates 401; The second mounting plates 101 are fixedly mounted on the front and rear side walls of the two first base plates 1, respectively. The four first mounting plates 401 are detachably connected to the second mounting plates 101 adjacent thereto by a plurality of screws 17. By aligning the first mounting plates 401 and the second mounting plates 101, the two can be fixed together by the plurality of screws 17.

[0025] The flip mechanism includes an n-shaped mounting frame 10, a first rectangular block 1001, a first connecting rod 15, and a connecting frame 1301; The same n-shaped mounting bracket 10 is slidably mounted between the two fixed guide rods 4 at the same end; First rectangular blocks 1001 are fixedly mounted on the outer walls of the two vertical rods of the two n-shaped mounting frames 10, and rectangular through holes are respectively provided on the four first rectangular blocks 1001; The four fixed guide rods 4 are respectively slidably arranged between the rectangular through holes adjacent thereto; The two n-shaped mounting frames 10 are respectively slidably mounted on the outer sides of the support frames 9 adjacent thereto; The inner walls of the two support frames 9 are respectively provided with a hollow groove 903, and the two flip protection plates 13 are respectively rotatably installed in the hollow groove 903 adjacent thereto; The first connecting shafts are fixedly mounted on the outer walls of the two vertical rods of the two n-shaped mounting frames 10, and the four first connecting shafts are respectively mounted on the inner sides of the first rectangular blocks 1001 adjacent thereto; The first ends of the first connecting rods 15 are rotatably mounted on the outer walls of the four first connecting shafts, and the connecting frames 1301 are fixedly mounted on both sides of the inner walls of the two flip protection plates 13. The second ends of the four first connecting rods 15 are rotatably mounted in the connecting frames 1301 adjacent thereto. The two n-shaped mounting frames 10 are driven to slide by the driving mechanism respectively; The two n-type mounting frames 10 are driven by sliding lifting mechanisms, respectively. Figure 7 When the equipment is in the initial state, the two support frames 9 are at the bottom, and the two N-type mounting frames 10 are also at the bottom of the two support frames 9. As the N-type mounting frames 10 slide upward under the drive mechanism, the two first connecting rods 15 close to the vertical plates of the two N-type mounting frames 10 begin to deflect upward and pull the two connecting frames 1301 on the inner wall of the flip protection plate 13 close to them during the deflection process to start deflecting upward. The flip protection plate 13 fixedly mounted with the two connecting frames 1301 now has the ability to deflect upward and eventually blocks the empty slot to achieve protection capability. When the flip protection plate 13 is fully raised, the N-type mounting frames 10 on both sides will continue to slide upward. At this time, the support frames 9 on both sides will be lifted by the lifting mechanism described later.

[0026] The driving mechanism includes a second connecting rod 11, a second rectangular block 1101, a driving motor 16, and a threaded rod 12; A second connecting shaft is fixedly mounted on the rear walls of the two first rectangular blocks 1001 close to the second expansion mounting plate 301; A second connecting rod 11 is fixedly installed between the two second connecting shafts, and a second rectangular block 1101 is fixedly installed at the rear of the middle end of the second connecting rod 11; The driving motor 16 is detachably mounted on the middle portion of the upper end of the second expansion mounting plate 301 via an angle iron, and a threaded rod 12 is fixedly mounted on the output shaft of the driving motor 16; A threaded connection is set between the threaded rod 12 and the second rectangular block 1101. By starting the drive motor 16, the output shaft of the drive motor 16 drives the threaded rod 12 fixedly installed coaxially with it to start rotating. The threaded rod 12 can drive the second rectangular block 1101 threadedly connected with it to start moving up and down by rotating. The second connecting rod 11 fixedly connected to the second rectangular block 1101 now has the ability to slide up and down, and the n-shaped mounting frame 10 fixedly installed at both ends of the second connecting rod 11 can now start moving up and down.

[0027] The lifting mechanism includes a first baffle 901 and a second baffle 902; The upper outer walls of the two support frames 9 are respectively fixedly mounted with first baffles 901, and the lower outer walls of the two support frames 9 are respectively fixedly mounted with second baffles 902; The two n-shaped mounting frames 10 are movably mounted between the first baffle 901 and the second baffle 902 adjacent thereto; The two N-type mounting frames 10 are respectively in detachable contact with the first baffle 901 close to them. When the two N-type mounting frames 10 slide upward to flip the two flip protective plates 13, the two N-type mounting frames 10 just contact the first baffle 901 at the upper end of the support frame 9 close to them. After contacting the first baffle 901, the N-type mounting frames 10 will continue to move upward. At this time, the N-type mounting frames 10 will lift the first baffle 901 and start to move upward, and the support frame 9 fixedly mounted with the first baffle 901 will start to move upward. As the support frame 9 moves upward, the flip protective plate 13 remains in a closed state, ensuring that the flip protective plate 13 is always in a closed state during the rising process and when the support frame 9 rises to the top, providing real-time protection for the construction workers in the support frame 9.

[0028] The sliding mechanism comprises a first rectangular slider 19 and a second connecting rod 5; Two first rectangular sliding grooves 1801 are respectively provided on the front and rear side walls of the connecting plate 18, and first rectangular sliding blocks 19 are slidably installed in the four first rectangular sliding grooves 1801; Two third connecting shafts are respectively installed on the inner walls of the first expansion mounting plate 3 and the second expansion mounting plate 301; The first ends of the second connecting rods 5 are rotatably mounted on the outer walls of the four third connecting shafts respectively; The outer walls of the four first rectangular sliders 19 are respectively fixed with fourth connecting shafts, and the second ends of the four second connecting rods 5 are respectively rotatably sleeved on the outer walls of the third connecting shafts adjacent thereto; The lower ends of the four sliding plates 6 are respectively mounted on the outer wall of the third connecting shaft adjacent thereto; The four sliding plates 6 are respectively installed between the second connecting rod 5 and the first rectangular slider 19 close thereto; The plurality of second protection rods 7 located on the outer wall of the same sliding plate 6 are all stored by the storage assembly; The four second protection rods 7 at the top are respectively in detachable contact with the first rectangular block 1001 adjacent thereto. As the support frames 9 on both sides are lifted upward, the connecting plate 18 fixedly installed between the two support frames 9 also begins to move upward. Figure 2 As the connecting plate 18 moves upward, the two second connecting rods 5 on both sides will start to rotate upward around their respective rotation centers. During the upward movement of the four second connecting rods 5, the four first rectangular sliders 19 close to them will slide along the first rectangular slide grooves 1801 cooperating therewith toward the middle of both sides of the connecting plate 18. The sliding plate 6 coaxially fixed with the four first rectangular sliders 19 will then slide toward the middle of both sides of the connecting plate 18 at the same time as the four first rectangular sliders 19. In the process of sliding toward the middle of both sides of the connecting plate 18, the four sliding plates 6 can respectively drive the several second protective rods 7 to slide toward the middle of both sides of the connecting plate. The several second protective rods 7 can close both sides of the connecting plate 18 by sliding, thereby protecting the construction personnel located on the connecting plate 18.

[0029] The storage assembly includes a return spring and a second rectangular slider 21; The outer walls of the four sliding rods 6 are respectively provided with second rectangular sliding grooves 601, and the inner ends of the second protective rods 7 are respectively fixedly mounted with second rectangular sliding blocks 21; A plurality of second rectangular sliding blocks 21 are respectively slidably installed in the second rectangular sliding grooves 601 adjacent thereto; The two adjacent second rectangular sliding blocks 21 in the same second rectangular chute 601 are connected by a return spring. Figure 8 The four second protection bars 7 at the top will start to move upward along with the N-shaped mounting frames 10 on both sides. During the upward movement of the four second protection bars 7 at the top, several reset springs will gradually reset and slowly expand the remaining second protection bars 7 longitudinally. When the N-shaped mounting frames 10 start to move downward, the two N-shaped mounting frames 10 will begin to compress the four second protection bars 7 at the top. As the two N-shaped mounting frames 10 continue to move downward, several second protection bars 7 are gradually compressed together for storage.

[0030] An opening and closing door 14 is rotatably installed in each of the two flip protective plates 13. The two opening and closing doors 14 are detachably connected to the flip protective plates 13 adjacent thereto through door locks. When the support frames 9 on both sides move upward to the highest point, the user can open the opening and closing door 14 and walk from the support frame 9 to the connecting plate 18, thereby greatly expanding the high-altitude construction area.

[0031] Implementation method of the present invention: Use a wrench to tighten the first base plate 1 and the second base plate 2 on both sides with nuts 20, and install the four fixed guide rods 4 and the first base plates 1 on both sides with screws; After installation, the first rectangular blocks 1001 on both sides of the two N-shaped mounting frames 10 are respectively placed on the fixed guide rods 4 close to them on both sides, and then the two support frames 9 are respectively assembled on the inner side of the cross bars of the N-shaped mounting frames 10 close to them by means of slide rails and slide grooves. At this time, the connecting plate 18 is connected between the bottoms of the two support frames 9 through the connecting piece. The connecting plate 18 can also be slidably assembled between the slide rails on both sides and the adjacent support frames 9 to prevent the connecting plate 18 from longitudinal displacement. It can also be fixed by screws. After the connecting plate 18 is fixed, the second connecting rods 11 on the outer sides of the four first rectangular sliders 19 on both sides are rotatably connected to the sliding plates 6 adjacent thereto, and the four sliding plates 6 are respectively sleeved on the fourth connecting shafts on the outer walls of the first rectangular sliders 19 adjacent thereto. At this time, the four second protective rods 7 located at the top on the outer walls of the four sliding plates 6 will be compressed by the two first rectangular blocks 1001 adjacent thereto, and the remaining second protective rods 7 are in a compressed and stored state. Fix the second connecting rod 11 to the two first rectangular blocks 1001 near the second expansion mounting plate 301 with screws. The second connecting rod 11, the second rectangular block 1101 and the threaded rod 12 can be assembled in advance, and the drive motor 16 coaxial with the threaded rod 12 is fixed to the second expansion mounting plate 301 with angle irons. After completing the above assembly, the first protection rods 8 are fixed to the first expansion mounting plate 3 by means of threaded connection to complete the assembly of the entire device. When the device is in the initial state Figure 9 As shown in Figure A, the two support frames 9 and the connecting plate 18 therebetween are located at the bottom, and the flip protection plates 13 on both sides are in a downwardly flipped out state. Since the flip protection plates 13 on both sides are flipped out downwardly, the empty slots 903 are exposed. At this time, the user can begin to walk through the empty slots 903 into one of the support frames 9; At this time, the drive motor 16 is started, and the output shaft of the drive motor 16 starts to rotate, driving the threaded rod 12 coaxially mounted therewith to start rotating. The threaded rod 12 rotates and drives the second connecting rod 11 to start sliding upward. The second connecting rod 11 gradually drives the N-shaped mounting brackets 10 on both sides to slide upward along the outer wall of the support frame 9 adjacent thereto. When the n-type mounting brackets 10 on both sides initially contact the first baffle 901 on the support frame 9 close to it, the flip protection plates 13 on both sides begin to flip upward to block the empty slot 903, and the support frame 9 can be closed at this time. Figure 10 The status shown; As the drive motor 16 continues to operate, the N-shaped mounting frames 10 on both sides will support the first baffles 901 on both sides and begin to slide upward. At this time, the support frames 9 on both sides will begin to slide upward along with the first baffles 901 fixed thereto, and support the construction workers. Since the N-shaped mounting frames 10 are always in contact with the first baffles 901 during the process of the two support frames 9 rising, the flip protection plate 13 is always in a closed state during this process. As the two support frames 9 slide upward, the four sliding rods 6 on both sides of the connecting plate 18 will begin to move toward the middle of both sides of the connecting plate 18. During the sliding process, the four sliding rods 6 will respectively drive the second protective rods 7 on their outer sides to expand and block both sides of the connecting plate 18. At this time, the device Figure 9 As shown in B; When the device is Figure 9 In the state shown in B, the construction workers can open the opening and closing door close to it and walk onto the connecting plate 18 or into the support frame 9 on the other side, which greatly increases the high-altitude construction area. When working on the connecting plate 18, the second protective rods 7 on both sides will also provide them with protection, which has strong safety.

[0032] The present invention can be assembled at the construction site using tools. The two support frames and connecting plates of the equipment can greatly increase the construction area on site and can effectively avoid frequent handling of equipment. The flipping mechanism of the equipment can flip up the flipping protective plate in advance and drive the support frame to rise and fall only after it is fully raised. When the support frame of the present invention rises upward, the second protective bars on both sides begin to unfold at the same time under the drive of the sliding mechanism, which further plays a protective role and has strong safety.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
