[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] See also Figure 1-Figure 7 The present embodiment is a lifting elevator for construction, comprising a car body 1, a long shaft 2 and a bracket 39, wherein a baffle 3 is provided 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, which is connected to the car body 1, so that the car body 1 can be lifted and lowered in the bracket 39.

[0021] The box 1 is provided with a flip mechanism, which is used to control the baffle 3 to rotate forward and backward. The flip mechanism includes a cylinder 5, a first convex plate 6, a short plate 7, a second convex plate 8, a long plate 9, a third convex plate 10; a connecting plate 11, and a connecting plate 12; A frame plate 4 is fixedly installed on the inner side of the box body 1, and the cylinder 5 is hinged to the inner side of the frame plate 4 through a rotating shaft, and the output end of the cylinder 5 is hinged to the short plate 7 through a rotating shaft; like Figure 5 , Figure 8As shown, the first convex plate 6 and the second convex plate 8 are respectively fixed on the inner side of the compartment 1, and the third convex plate 10 is fixedly installed on the back side of the baffle 3. The side surface of the first convex plate 6 is hinged to one end of the short plate 7 through a rotating shaft; the side surface of the second convex plate 8 is hinged to one end of the long plate 9 through a rotating shaft, and one end of the connecting plate 11 and the connecting plate 12 are respectively hinged to the third convex plate 10 through rotating shafts, and the other end of the connecting plate 11 is hinged to the short plate 7 through a rotating shaft, and the other end of the long plate 9 is hinged to the other end of the connecting plate 12 through a rotating shaft, and the side surface of the connecting plate 11 is hinged to the side surface of the long plate 9 through a rotating shaft.

[0022] 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 in the opposite direction along the second convex plate 8 under the action of the connecting plate 11, so that under the joint action of the connecting plate 11 and the connecting plate 12, the baffle 3 will be driven to flip 90 degrees in the opposite direction, so that the baffle 3 can be driven to press against the gap between the building and the elevator, and can cooperate with the guardrail 13 to effectively improve the safety, eliminating the need to build a scaffolding. During the contraction of the cylinder 5, the baffle 3 can be driven to flip in the opposite direction and the guardrail 13 can be driven to be stored, so as to achieve the effect of closing the car body 1.

[0023] During the operation of the cylinder 5, the short plate 7 and the long plate 9 cooperate to turn the baffle plate 3 out 90 degrees, thereby effectively blocking the gap between the elevator and the building, thereby improving safety.

[0024] In one embodiment, the output end of the cylinder 5 is hinged to the short plate 7 via a rotating shaft, and the connecting plate 12 is hinged to the third convex plate 10 via a rotating shaft. By setting the short plate 7 and the connecting plate 12, the baffle 3 can be driven to flip over during the operation of the cylinder 5 with the cooperation between the connecting plate 11, the connecting plate 12, the short plate 7, and the long plate 9. The process is stable and can cooperate with the guardrail 13 to effectively improve safety and practicality.

[0025] like Figure 2 As shown, the lifting mechanism includes a motor 35; the motor 35 is fixed to the top of the bracket 39, and a worm 36 is connected to the output end of the motor 35; a first guide wheel 32 and a second guide wheel 33 are provided on the bracket 39, and a steel cable 34 is provided on the first guide wheel 32 and the second guide wheel 33, and a counterweight 37 is provided at one end of the steel cable 34, and the other end is fixed to the top of the compartment 1; a worm wheel 38 is fixedly installed on the back of the first guide wheel 32, and the worm wheel 38 is meshed with the worm 36.

[0026] The design of the first guide wheel 32 and the second guide wheel 33 ensures that the steel cable 34 can pass smoothly during operation and can maintain the correct position and direction of the steel cable 34, which is crucial to the stability and safety of the car body 1 and avoids the risk of accidents caused by friction or incorrect guidance. The motor 35 needs to overcome gravity and the weight of the elevator itself during operation. The use of the counterweight block 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 block 37 can ensure that the car body 1 remains vertical and stable during operation, reduce the possibility of operating failures or accidents caused by load imbalance, and improve the safety of the car body 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 wheel 38 and the first guide wheel 32 to rotate, and then under the action of the counterweight block 37 and the steel cable 34, the car body 1 will be driven to rise along the bracket 39.

[0027] In one embodiment, the guardrails 13 are in two groups and are symmetrically distributed on the back of the baffle 3. The two groups of guardrails 13 can effectively improve safety, prevent passengers from falling sideways when coming out of the elevator, and reduce safety hazards.

[0028] like Figure 3 , Figure 4 As shown, a rotating mechanism is provided between the long shaft 2 and the baffle 3, and the rotating mechanism includes a fourth convex plate 14 and a gear mechanism, and the gear mechanism includes a first gear 15 and a toothed plate 16; one end of the fourth convex plate 14 is fixedly mounted on the side of the long shaft 2, and the other end is fixed to the first gear 15; the toothed plate 16 is fixed on the baffle 3 and meshes with the first gear 15; 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 fixing plate 19 is fixedly installed on the surface of the baffle 3, and a second gear 20 and a third gear 21 meshing with the second gear 20 are provided on the side of the fixing plate 19, and a second pulley 22 is fixed on the side of the second gear 20, and the belt 18 is located on the first pulley 17 and the second pulley 22; an extension plate 23 is slidably connected to the inner side of the baffle 3, a tooth groove 31 is opened on the inner side of the extension plate 23, and an opening corresponding to the tooth groove 31 is opened on the baffle 3, and the third gear 21 meshes with the tooth groove 31.

[0029] During the flipping process of the baffle plate 3, the long shaft 2 will be driven to rotate, and then the fourth convex plate 14 will be driven to change its position. During this process, the first gear 15 will be driven to move and the first gear 15 and the first pulley 17 will be driven to rotate under the action of the tooth plate 16. At this time, the second pulley 22 will be driven to rotate under the action of the belt 18, thereby driving the second gear 20 to rotate, and the third gear 21 will be driven to rotate under the meshing action. During the rotation of the third gear 21, the extension plate 23 will be driven to extend from the inner side of the baffle plate 3 under the action of meshing with the tooth groove 31, thereby effectively increasing the contact area between the baffle plate 3 and the ground, improving the stability during walking on the baffle plate 3, and the extension plate 23 can be automatically retracted during the rising process of the baffle plate 3, thereby lengthening the length of the baffle plate to avoid the situation that the baffle plate is not long enough due to the long distance between the elevator and the building, and the extension plate can be automatically retracted during the rising process of the baffle plate. Figure 6 , Figure 7 shown.

[0030] During the meshing process between the tooth 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, the first pulley 17 can be driven to rotate under the action of the first gear 15, thereby driving the second pulley 22 to rotate under the action of the belt 18.

[0031] During the meshing process between the third gear 21 and the second gear 20, the third gear 21 meshes with the tooth groove 31, which can drive the second gear 20 to rotate during the rotation of the second pulley 22, 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.

[0032] The first pulley 17 is rotatably connected to the fourth convex plate 14 , and can drive the second pulley 22 to rotate under the action of the belt 18 during the rotation of the first pulley 17 , thereby achieving a transmission effect.

[0033] like Fig. 9 , Fig.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.

[0034] 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.

[0035] 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.
