Description

Technical Field

[0001] The present invention relates to the technical field of lifting elevators, and particularly to a lifting elevator convenient for building construction. Background Art

[0002] The lifting elevator for building construction is a key device used to quickly and safely transport workers, tools, and materials from the ground to the high-altitude working area, or to perform vertical transportation between different floors. These elevators play an important role in modern construction sites, improving work efficiency and safety. A lifting device for building construction (CN210710252U) includes a lifting elevator. A fixed plate is fixedly installed at the lower end of the inner wall of the lifting elevator. The left and right side walls of the fixed plate are hinged with a first limiting plate. A first through hole is opened at the rear end of the inner wall of the lifting elevator. A receiving plate is fixedly installed at the rear end of the outer wall of the lifting elevator. The rear side wall of the receiving plate is hinged with a rotating rod. A telescopic rod is fixedly installed on the upper surface of the rotating rod. The upper side wall of the telescopic rod is fixedly connected to a top plate. A magnet rod is fixedly installed on the front side wall of the top plate. A first fixing groove is opened on the lower surface of the top plate. A magnet plate is fixedly installed on the inner wall of the first fixing groove. During the movement of the lifting elevator, it adsorbs steel bars and iron pipes, reducing the bump of the steel bars or iron pipes, achieving the purpose of transporting steel bars and iron pipes that could not be accommodated by the original lifting elevator without overloading, and reducing the waste of construction resources at the construction site. However, this kind of lifting device is the same as the current lifting devices for building construction on the market. Generally, there will be a gap between the lifting elevator and the building. If it is getting dark or the passengers do not pay attention to the situation under their feet, there may be a risk of stepping into the void or falling, which has a very large safety hazard.

[0034] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0035] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0036] Please refer to Figures 1 - 7 , a lift for building construction in this embodiment includes a compartment body 1, a long shaft 2 and a bracket 39. A baffle 3 is arranged on the surface of the long shaft 2, and guardrails 13 are fixedly installed on both sides of the back of the baffle 3. The bracket 39 is provided with a lifting mechanism, and the lifting mechanism is connected to the compartment body 1 to lift the compartment body 1 in the bracket 39.

[0037] A flipping mechanism is arranged inside the compartment body 1, and the flipping mechanism is used to control the baffle 3 to rotate forward and backward. The flipping mechanism includes a cylinder 5, a first convex plate 6, a short board 7, a second convex plate 8, a long board 9, a third convex plate 10; a connecting board 11, a connecting plate 12;

[0038] The frame plate 4 is fixedly installed inside the compartment body 1, the cylinder 5 is hinged inside the frame plate 4 through a rotating shaft, and the output end of the cylinder 5 is hinged to the short board 7 through a rotating shaft;

[0039] Such as Figure 5 , Figure 8As shown, the first convex plate 6 and the second convex plate 8 are respectively fixed to the inner side of the compartment 1, and the third convex plate 10 is fixedly installed on the back of the baffle 3. One end of the short plate 7 is hinged to the side of the first convex plate 6 through a rotating shaft; one end of the long plate 9 is hinged to the side of the second convex plate 8 through a rotating shaft. One ends of the connecting plate 11 and the connecting plate 12 are respectively hinged to the third convex plate 10 through a rotating shaft. The other end of the connecting plate 11 is hinged to the short plate 7 through a rotating shaft. The other end of the long plate 9 is hinged to the other end of the connecting plate 12. The side of the connecting plate 11 is hinged and connected to the side of the long plate 9 through a rotating shaft.

[0040] Start the cylinder 5 and drive the short plate 7 to rotate forward along the first convex plate 6. During the rotation of the short plate 7, the long plate 9 will be driven to rotate reversely along the second convex plate 8 under the action of the connecting plate 11. Thus, under the combined action of the connecting plate 11 and the connecting plate 12, the baffle 3 will be driven to perform a 90-degree reverse flip, so that the baffle 3 can be driven to abut against the gap between the building and the lift. And it can effectively improve the safety in cooperation with the guardrail 13, eliminating the need to build a scaffolding. During the contraction of the cylinder 5, the baffle 3 can be driven to reverse flip and drive the guardrail 13 to be stored, so as to achieve the effect of closing the compartment 1.

[0041] During the operation of the cylinder 5, cooperate with the short plate 7 and the long plate 9 to perform the 90-degree flipping out operation of the baffle 3, so that the gap between the lift and the building can be effectively blocked, thereby improving the safety.

[0042] In one embodiment, the output end of the cylinder 5 is hinged to the short plate 7 through a rotating shaft, and the connecting plate 12 is hinged to the third convex plate 10 through a rotating shaft. By setting the short plate 7 and the connecting plate 12, during the operation of the cylinder 5, under the mutual cooperation among the connecting plate 11, the connecting plate 12, the short plate 7 and the long plate 9, the baffle 3 can be driven to flip. The process is stable and can effectively improve the safety and practicality in cooperation with the guardrail 13.

[0043] As Figure 2 As shown, the lifting mechanism includes a motor 35; the motor 35 is fixed to the top of the bracket 39. The output end of the motor 35 is connected and installed with a worm 36. The bracket 39 is provided with a first guide wheel 32 and a second guide wheel 33. A steel cable 34 is provided on the first guide wheel 32 and the second guide wheel 33. One end of the steel cable 34 is provided with a counterweight 37, and the other end is fixed to the top of the compartment 1; a worm gear 38 is fixedly installed on the back of the first guide wheel 32, and the worm gear 38 meshes with the worm 36.

[0044] The design of the first guide wheel 32 and the second guide wheel 33 ensures that the steel cable 34 can pass through smoothly during operation and can maintain the correct position and direction of the steel cable 34, which is crucial for the stability and safety of the cabin 1 and avoids the risk of accidents that may be caused by friction or incorrect guidance. When the motor 35 is running, it needs to overcome gravity and the weight of the elevator itself. The use of the counterweight 37 can reduce the actual load that the elevator motor 35 needs to bear, thereby extending the service life of the motor 35 and improving energy efficiency. The correct use of the counterweight 37 can ensure that the cabin 1 remains vertical and stable during operation, reducing the possibility of operating failures or accidents caused by load imbalance and improving the safety of the cabin 1. Start the motor 35 and drive the worm 36 to rotate. At this time, under the meshing action, the worm 36 will drive the worm gear 38 and the first guide wheel 32 to rotate, and then under the action of the counterweight 37 and the steel cable 34, the cabin 1 will be driven to rise along the bracket 39.

[0045] In one embodiment, the number of the guardrails 13 is two groups and they are symmetrically distributed on the back of the baffle 3. The two groups of guardrails 13 can effectively improve safety, prevent passengers from falling from the side when getting out of the inside of the lift elevator, and reduce potential safety hazards.

[0046] As Figure 3 、 Figure 4 shown, a rotating mechanism is provided between the long shaft 2 and the baffle 3. The rotating mechanism includes a fourth convex plate 14 and a gear mechanism. The gear mechanism includes a first gear 15 and a toothed plate 16. One end of the fourth convex plate 14 is fixedly installed on the side of the long shaft 2, and the other end fixes the first gear 15. The toothed plate 16 is fixed on the baffle 3 and meshes with the first gear 15.

[0047] A first pulley 17 is fixedly installed on the side of the fourth convex plate 14, and a belt 18 is sleeved on the surface of the first pulley 17. A fixed plate 19 is fixedly installed on the surface of the baffle 3. A second gear 20 and a third gear 21 meshing with the second gear 20 are provided on the side of the fixed plate 19. A second pulley 22 is fixed on the side of the second gear 20. The belt 18 is located on the first pulley 17 and the second pulley 22. An extension plate 23 is slidably connected to the inside of the baffle 3. A tooth groove 31 is opened on the inside of the extension plate 23, and an opening corresponding to the tooth groove 31 is opened on the baffle 3. The third gear 21 meshes with the tooth groove 31.

[0048] During the flipping process of the baffle 3, it will drive the long shaft 2 to rotate, and further drive the fourth convex plate 14 to change its position. During this process, it will drive the first gear 15 to displace and drive the first gear 15 and the first pulley 17 to rotate under the action of the toothed plate 16. At this time, under the action of the belt 18, it will drive the second pulley 22 to rotate, thereby driving the second gear 20 to rotate. Under the meshing action, it will drive the third gear 21 to rotate. During the rotation of the third gear 21, it will drive the extension plate 23 to extend from the inner side of the baffle 3 under the action of meshing with the tooth groove 31. Thus, it can effectively increase the contact area between the baffle 3 and the ground, improve the stability during walking on the baffle 3, and can automatically complete the storage of the extension plate 23 during the rising process of the baffle 3. Thereby, it can lengthen the length of the baffle, avoid the situation that the length of the baffle is insufficient due to the excessive distance between the lifting elevator and the building, and can automatically complete the storage of the extension plate during the rising process of the baffle as Figure 6 、 Figure 7 shown.

[0049] During the meshing process of the toothed plate 16 and the first gear 15, the first pulley 17 is connected to the second pulley 22 through the belt 18. During the flipping process of the baffle 3, under the action of the first gear 15, it can drive the first pulley 17 to rotate, and thereby drive the second pulley 22 to rotate under the action of the belt 18.

[0050] During the meshing process of the third gear 21 and the second gear 20, the third gear 21 meshes with the tooth groove 31. During the rotation of the second pulley 22, it can drive the second gear 20 to rotate, and then drive the third gear 21 to rotate under the meshing action, and drive the extension plate 23 to extend from the inner side of the baffle 3 under the action of the tooth groove 31.

[0051] The first pulley 17 is rotationally connected to the fourth convex plate 14. During the rotation of the first pulley 17, it can drive the second pulley 22 to rotate under the action of the belt 18, thereby achieving the transmission effect.

[0052] As Figure 9 、 Figure 10The box 1 is provided with detachable mirrors 29 on both sides. A boss 24 is fixedly mounted on the surface of the box 1, a slot 25 is provided on the inner side of the boss 24, a thread groove 26 is provided on the inner side of the boss 24, an insert block 27 is inserted on the inner side of the slot 25, a connecting rod 28 is fixedly mounted on the surface of the insert block 27, one end of the connecting rod 28 is fixedly mounted with the mirror 29, a limiting sleeve 30 is sleeved on the surface of the connecting rod 28, a thread is provided on the inner side of the limiting sleeve 30, the thread provided on the inner side of the limiting sleeve 30 is consistent with the thread on the inner side of the thread groove 26, the limiting sleeve 30 is rotated and the limiting sleeve is driven by the action of the thread The sleeve 30 is disengaged from the inner side of the threaded groove 26, so that the limiting sleeve 30 no longer presses against the connecting rod 28 and the insert block 27. At this time, the insert block 27 can be pulled out from the inner side of the slot 25 and the mirror 29 can be replaced and maintained. The surrounding environment and the position of other staff can be understood by observing the mirror 29 during the process of entering and exiting from the inside of the car body 1, which can provide a wider field of vision perception, making workers feel safer when using the elevator. They can more easily observe the surrounding environment and the position of other staff, reducing the risk of collision and accidents.

[0053] In one embodiment, a thread is provided on the inner side of the limit sleeve 30, and the thread provided on the inner side of the limit sleeve 30 is consistent with the thread on the inner side of the thread groove 26. During the rotation of the limit sleeve 30, the thread can drive the limit sleeve 30 to screw into the inner side of the thread groove 26, thereby limiting the insertion block 27.

[0054] Working principle: When working, the passengers first enter the inner side of the compartment 1, then start the cylinder 5 and retract it. At this time, the cylinder 5 will drive the short plate 7 to rotate backward along the first convex plate 6. During the rotation of the short plate 7, the long plate 9 will be driven to rotate backward along the second convex plate 8 under the action of the connecting plate 11, so that the baffle 3 will be turned 90 degrees under the joint action of the connecting plate 11 and the connecting plate 12, and then the baffle 3 and the guardrail 13 can be stored into the inner side of the compartment 1, and then the motor 35 is started and the worm 36 is driven to rotate. At this time, the worm 36 will drive the worm wheel 38 and the first guide wheel 32 under the meshing action. The car body 1 is then driven to rise along the bracket 39 under the action of the counterweight block 37 and the steel cable 34. After reaching the destination, the cylinder 5 is then started to drive the short plate 7 to rotate forward along the first convex plate 6. During the rotation of the short plate 7, the long plate 9 is driven to rotate in the opposite direction along the second convex plate 8 under the action of the connecting plate 11. As a result, the baffle plate 3 is driven to reversely flip 90 degrees under the joint action of the connecting plate 11 and the connecting plate 12, so that the baffle plate 3 can be driven to resist the gap between the building and the elevator. During the flipping of the baffle plate 3, the long shaft 2 is driven to rotate, which in turn drives the fourth convex plate 14 to change its position. During this process, the first gear 15 is displaced and the first gear 15 and the first pulley 17 are rotated under the action of the tooth plate 16. At this time, the second pulley 22 is rotated under the action of the belt 18, so that the second gear 20 can be rotated. The third gear 21 is rotated under the meshing action, and the extension plate 23 is extended from the inner side of the baffle 3 under the action of meshing with the tooth groove 31, thereby effectively increasing the contact area between the baffle 3 and the ground, improving the stability of walking on the baffle 3, and the surrounding environment can be understood by observing the mirror 29 during the process of entering and exiting from the inner side of the compartment 1. The position of the environment and other staff can be adjusted, thereby reducing the risk of collision and accidents. When the mirror 29 needs to be replaced, the limiting sleeve 30 is first rotated and driven to disengage from the inner side of the thread groove 26 under the action of the thread, so that the limiting sleeve 30 is no longer against the connecting rod 28 and the plug block 27. At this time, the plug block 27 can be pulled out from the inner side of the slot 25 and the mirror 29 can be replaced and maintained. During installation, the plug block 27 is first inserted from the inner side of the slot 25, and then the limiting sleeve 30 is aligned with the thread groove 26 and rotated. At this time, the thread will screw it into the inner side of the thread groove 26 under the action of the thread, and the plug block 27 is limited.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
