Description

Technical Field

[0001] The utility model relates to a rotatable anti-falling device for an elevator shaft at a working floor. Background Art

[0002] With the continuous advancement of urbanization, my country's construction industry has also achieved rapid development, and the amount of construction projects has increased year by year. However, in a large number of construction projects, due to factors such as the large number of construction personnel, high mobility, and complex types of work, the safety management of the construction site is very difficult, and safety accidents on the construction site occur from time to time, threatening the overall safety of the project construction. At present, one of the most common accidents on construction sites is a fall accident. For construction areas that change greatly after daily operations on the working floor, it is very easy for the elevator shaft to lack safety protection measures and untimely edge protection. To this end, the utility model proposes a revolving anti-fall device for the working floor elevator shaft to solve the above problems. Utility Model Content

[0003] The utility model provides a rotatable anti-falling device for an elevator shaft at a working floor, which can effectively solve the above-mentioned problem.

[0004] The utility model is achieved in this way:

[0005] A rotatable anti-falling device for an elevator shaft at a working floor, comprising a protective frame formed by the intersection of a plurality of square tube keels;

[0006] A number of the square tube keels are fixedly provided with perforated steel meshes, and a steel hinge for fixed connection is provided between two adjacent perforated steel meshes, and a steel lifting lug for cooperating with the crane is provided between any two groups of the steel hinges, and a latch fixture is provided at the connecting end of any two groups of the square tube keels, and a steel latch for engaging with the hole of the aluminum alloy template K plate is provided in the latch fixture, so as to fix the protective frame;

[0007] A plurality of the steel latches are sleeved with a buffer component, which is used to prevent the protective frame from being impacted and shaken.

[0008] As a further improvement, the buffer assembly includes a hollow iron block; an intermediate piece is fixedly provided in the middle of the first end of the iron block, a locking rod piece is rotatably provided in the middle of the intermediate piece, a buffer rod is fixedly provided on the outer wall of the locking rod piece, a buffer pad in contact with the wall is fixedly provided at one end of the buffer rod, and abutment rods for contacting the buffer rod are provided at the upper and lower ends of the intermediate piece.

[0009] As a further improvement, an inclined portion is formed at one end of the abutment rod, and a plurality of protrusions are provided on the inclined surface of the inclined portion.

[0010] As a further improvement, the abutment rod is made of stainless steel.

[0011] As a further improvement, the protection frame is in a shape of a triangle, a square or a rectangle.

[0012] As a further improvement, a convex point is formed in the middle of the iron block, and the convex point contacts the outer wall of the steel pin and is effectively connected to the steel pin.

[0013] The beneficial effects of the utility model are:

[0014] (1) A number of square tube keels are assembled and welded, and then the perforated steel mesh is fixed to the square tube keels through a steel hinge, so that the perforated mesh can fill the gaps between the square tube keels and improve the safety of the protective frame. Then, the assembled protective frame is fixed to the four sides of the elevator shaft through steel pins and pin fixers. The protective frame cover is set at the elevator shaft, so as to prevent workers from falling into the elevator shaft due to accidents, thereby improving the safety during construction. At the same time, compared with the existing traditional manual steel pipe edge protection method, the structure set by the utility model improves the timeliness of edge protection. Furthermore, the setting of the steel lifting ear can facilitate the turnover of the entire protective frame through the crane, which is simple and fast, and is conducive to the use of subsequent projects.

[0015] (2) Since the iron block is sleeved on the steel pin, when the protective frame is subjected to external force, the abutment rod is subjected to force and may move up and down due to the setting of the locking rod. However, due to the setting of the buffer rod, the abutment rod can abut against the inclined surface at one end of the buffer rod. At the same time, the buffer pad at one end of the abutment rod contacts the wall, which can achieve a certain buffering effect and further enhance the stability and safety of the protective frame.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are 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 making creative work belong to the scope of protection of the utility model.

[0024] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] Reference Figure 1-4 As shown, a rotatable anti-fall device for an elevator shaft at a working level includes a protective frame formed by the intersection of a plurality of square tube keels 1. A plurality of steel latches 5 are sleeved with a buffer assembly, which is used to prevent the protective frame from being impacted and shaken. The shape of the protective frame is a triangle, a square or a rectangle. As an embodiment of the utility model, the protective frame is preferably a triangle. This is because the triangle has natural stability, and its structural characteristics enable it to maintain its shape and not easily deform when subjected to external forces. In contrast, a square frame may be more likely to deform when subjected to external forces in certain directions.

[0026] A number of square tube keels 1 are fixed with perforated steel meshes 2, and a steel hinge 3 is provided between two adjacent perforated steel meshes 2 for fixed connection. The perforated steel meshes 2 have strong anti-deformation performance, and the "four-in-one" installation is easy. Between any two sets of steel hinges 3, a steel lifting lug 4 for cooperating with the crane is provided, and the connecting ends of any two sets of square tube keels 1 are provided with a latch fixer 6, and the latch fixer 6 is provided with a steel latch 5 for connecting with the holes of the aluminum alloy template K plate, so as to fix the protective frame.

[0027] When in use, several square tube keels 1 are assembled and welded, and then the perforated steel mesh 2 is fixed to the square tube keel 1 by the steel hinge 3, so that the perforated mesh 2 can fill the gap between the square tube keels 1, thereby improving the safety of the protective frame. Then, the assembled protective frame is fixed to the four sides of the elevator shaft opening by the steel latch 5 and the latch fixer 6, and the protective frame cover is arranged at the elevator shaft opening, so as to prevent the staff from falling into the elevator shaft opening due to accidents, thereby improving the safety during construction operations. At the same time, compared with the existing traditional manual construction of steel pipe edge protection, the structure provided by the utility model improves the timeliness of edge protection. Furthermore, the provision of the steel lifting ear 4 can facilitate the turnover of the entire protective frame through the crane, which is simple and fast, and is conducive to the use of subsequent projects.

[0028] It should be noted that the materials in this case can be selected and processed from the leftover materials on site, and the cost of the entire structure is low, which is conducive to popularization and use.

[0029] The buffer assembly includes a hollow iron block 7; an intermediate piece 8 is fixedly provided in the middle of the first end of the iron block 7, a locking rod 12 is rotatably provided in the middle of the intermediate piece 8, a buffer rod 9 is fixedly provided on the outer wall of the locking rod 12, a buffer pad 13 in contact with the wall surface is fixedly provided at one end of the buffer rod 9, and an abutment rod 10 for contacting the buffer rod 9 is provided at the upper and lower ends of the intermediate piece 8, and the abutment rod 10 is made of stainless steel. Specifically, an inclined portion 14 is formed at one end of the abutment rod 10, and a plurality of protrusions are provided on the inclined surface of the inclined portion 14, and the protrusions contact the buffer rod 9 when the buffer rod 9 moves, thereby increasing the friction between the abutment rod 10 and the buffer rod 9, and ensuring that the buffer rod 9 does not move after being subjected to force.

[0030] Among them, since the iron block 7 is sleeved on the steel pin 5, when the protective frame is subjected to external force, the abutment rod 10 is subjected to force and may move up and down due to the setting of the locking rod 12. However, due to the setting of the buffer rod 9, the abutment rod 10 can abut against the inclined surface at one end of the buffer rod 9. At the same time, the buffer pad 13 at one end of the abutment rod 10 contacts the wall, which can have a certain buffering effect and further enhance the stability and safety of the protective frame.

[0031] Furthermore, after the abutment rod 10 is subjected to force, an angle A is formed, and the angle A is not limited. This is because when the angle of the abutment rod 10 is too large, the contact area between the abutment rod 10 and the wall surface may be reduced, thereby reducing stability. Therefore, a moderate inclination angle can provide sufficient support force and reduce stress concentration, thereby increasing stability. The specific implementation can be set according to actual needs.

[0032] A convex point is formed in the middle of the iron block 7, and the convex point contacts the outer wall of the steel pin 5 and is effectively connected to the steel pin 5, thereby improving the connectivity between the iron block 7 and the steel pin 5.

[0033] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
