DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 2 , Figure 4 , the utility model provides an embodiment: a safety protection device for a construction elevator, including an elevator 1, the elevator 1 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The upper surface of the elevator 1 is fixedly connected to a platform 2, and a rectangular groove 2 5 is opened on the front surface of the platform 2. A through groove 3 6 is opened on the right side of the front surface of the platform 2 adjacent to the rectangular groove 2 5, and the through groove 3 6 is horizontal to the left and right to ensure that the round rod 33 can only move horizontally to the left and right. A fixing component 3 is arranged on the inner wall of the platform 2, and an extension component 4 is arranged on the inner wall of the fixing component 3. The fixing component 3 includes a protective shell 31, and the protective shell 31 is slidably connected to the upper surface of the platform 2. A rectangular groove 1 35 is opened on the inner wall of the front end of the protective shell 31, and the rectangular groove 1 35 is adapted to the rectangular block 34 to ensure the stability of the limit. A through groove 2 310 is opened on the right surface of the protective shell 31, and a rectangular block 34 is slidably connected to the inner wall of the front end of the platform 2, and the right end of the rectangular block 34 contacts the inner wall of the rectangular groove 1 35.

[0032] Reference Figure 1 - Figure 2 The extension component 4 includes an extension protective plate 41. The connection distance between the extension protective plate 41 and the protective shell 31 can be adjusted to ensure that workers of different heights can be safely protected. The extension protective plate 41 is slidably connected to the inner wall of the protective shell 31. The right surface of the bottom end of the extension protective plate 41 is fixedly connected with a moving block 44. The moving block 44 is slidably connected to the inner wall of the second through groove 310. The moving block 44 is adapted to the second through groove 310 to ensure the stability of the moving block 44 when moving up and down. The moving block 44 slides through the upper surface of the platform 2.

[0033] Reference Figure 2 , Figure 4The fixing assembly 3 also includes a round rod 33, which passes through and is fixedly connected to the left end of the front surface of the rectangular block 34. Pushing the round rod 33 can drive the rectangular block 34 to move, thereby ensuring the smoothness of the structural coordination. The outer wall of the front end of the round rod 33 is slidably connected to the inner wall of the through groove three 6. The inner wall of the rectangular groove two 5 is elastically connected to a slider 37 through a spring 38. The spring 38 always pushes the slider 37 to move upward, thereby ensuring that the rectangular block 34 is always in contact with the inside of the rectangular groove one 35 to ensure the stability of the limit without pushing the push plate 32. The slider 37 slides on the inner wall of the rectangular groove two 5, one end of the spring 38 is fixedly connected to the inner wall of the rectangular groove two 5, and the other end of the spring 38 is fixedly connected to the lower surface of the slider 37.

[0034] Reference Figure 4 The front surface of the slider 37 is fixedly connected to the push plate 32, and the front surface of the push plate 32 is provided with a through groove 39. The through groove 39 has a certain inclination to ensure that when the push plate 32 is pushed, the round rod 33 will move along the inclination of the through groove 39, and the front end outer wall of the round rod 33 is adjacent to the front side of the through groove 36 and is slidably connected to the inner wall of the through groove 39.

[0035] Reference Figure 2 - Figure 3 The inner wall at the right end of the rectangular block 34 is rotatably connected to a roller 36. The roller 36 can reduce the friction between the rectangular block 34 and the protective shell 31, ensuring that the worker can smoothly pull up the protective shell 31. The roller 36 rolls on the inner wall at the front end of the protective shell 31. There are multiple groups of rectangular blocks 34, and the multiple groups of rectangular blocks 34 are symmetrically arranged with the center line of the platform 2 as the symmetry axis. The arrangement of multiple groups of rectangular blocks 34 can ensure the stability of the limit.

[0036] Reference Figure 1 - Figure 2 The extension component 4 also includes a fixed block 43, which is fixedly connected to the top of the right surface of the protective shell 31. A threaded rod 42 is rotatably connected to the upper surface of the fixed block 43. The threaded rod 42 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. At the same time, it has the characteristics of self-locking up and down to ensure the stability of the structural connection. The threaded rod 42 is connected to the upper surface of the moving block 44.

[0037] Working principle: When the goods need to be placed on the upper surface of the platform 2, if there is an obstruction, the push plate 32 can be pushed, and the round rod 33 will move along the slope of the through slot 1 39, and the round rod 33 will drive the rectangular block 34 to move, and the push plate 32 will drive the slider 37 to slide on the inner wall of the rectangular slot 2 5, and the slider 37 will squeeze the spring 38 until the rectangular block 34 is completely separated from the inner wall of the rectangular slot 1 35, and the protective shell 31 will fall under the gravity, so that the protective shell 31 will be hidden under the platform 2 , then the device can be placed on the upper surface of the platform 2. During this process, the rectangular block 34 is always on the inner wall of the platform 2, and the left and right rollers 36 are in contact with the protective shell 31. When the protective shell 31 is pulled up, the rollers 36 will roll until the rectangular block 34 overlaps with the rectangular groove 35. At this time, the spring 38 will push the slider 37 through its own elasticity to reset the push plate 32 in the opposite direction. The subsequent contact and matching method is the same as above, so that the rectangular block 34 will enter the inner wall of the rectangular groove 35 to limit the protective shell 31.

[0038] When the height of the extended protective plate 41 needs to be adjusted, it is only necessary to rotate the threaded rod 42. At this time, the moving block 44 threadedly connected to the outer wall of the threaded rod 42 will slide on the inner wall of the through groove 310, and the moving block 44 will drive the extended protective plate 41 to move. In this way, the height of the extended protective plate 41 can be adjusted, and the stability of the extended protective plate 41 can be guaranteed through the upper and lower self-locking characteristics of the threaded rod 42.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
