Description

Technical Field

[0001] The utility model belongs to the field of protective devices, in particular to a construction protective device for safety engineering. Background Art

[0002] Safety engineering is a comprehensive discipline involving natural sciences, social sciences, engineering technology and other fields. It aims to prevent and reduce accidents through scientific methods and effective management, protect human life and health, protect the environment, and prevent property losses. Its main contents include safety science foundation, safety technology, safety management, safety regulations and standards, and safety culture. There is a close relationship between safety engineering and construction protective devices. The goal of safety engineering is to prevent and reduce accidents through a series of measures, and construction protective devices are an important part of these measures. By properly installing and using protective devices, the risk of accidents on the construction site can be effectively reduced and the lives of workers can be protected.

[0003] The hanging basket is a commonly used high-altitude construction tool on construction sites. It is used for wall construction such as tiling exterior wall tiles, painting, spraying, etc. It is a construction equipment that is erected on a building or structure through a lifting mechanism and a hanging platform. The lifting mechanism moves the hanging basket up and down along the building through steel cables, thereby performing operations on the surface of the building. However, the top of the hanging basket is usually an open structure design, and there is no protective device to protect the construction workers. When the undried tiles on the wall fall off, the wall skin falls off, or objects fall from high altitude, it is easy to cause life-threatening danger to the construction workers on the hanging basket. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is: to provide a construction protection device for safety engineering, which can protect the construction workers on the hanging basket and prevent the construction workers from being injured.

[0005] The construction protection device for safety engineering comprises a baffle, a plurality of support columns for installation on a hanging basket are vertically fixed at the bottom of the baffle, a protection net parallel and aligned therewith is arranged above the baffle, and the baffle and the protection net are in an inclined top shape to facilitate objects to slide down; a support frame for supporting the protection net is fixed along the edge thereof; a plurality of support rods for supporting the protection net are fixed in the support frame, and a plurality of top blocks for colliding with external objects are fixed on all the support rods; a connecting assembly for allowing the support frame to move up and down and limiting the moving distance is arranged between the support frame and the baffle; a plurality of buffers are installed on the baffle, and the telescopic ends of all the buffers are fixed to the corresponding support rods.

[0006] Furthermore, the connecting assembly includes a plurality of inner tubes, one end of which is fixed on a support frame, each inner tube is independently sleeved with an outer tube, a spring is sleeved on the inner tube, and the spring is located between the outer tube and the support frame. One end of all the outer tubes is fixed on a baffle, a slide groove communicating with the inside and outside is opened on the tube wall of each outer tube, a threaded hole is opened on the inner tube corresponding to the slide groove, positioning screws are installed in all the slide grooves, and the threaded end of each positioning screw is threadedly matched with the threaded hole at the corresponding position.

[0007] Furthermore, the baffle is provided with a plurality of through holes which are connected to each other from top to bottom, and transparent plates for sealing the through holes are fixed in all the through holes.

[0008] Furthermore, the top block has a conical structure.

[0009] Furthermore, all the top blocks on each support rod are arranged at equal intervals.

[0010] Furthermore, the protective net is made of metal material.

[0011] Furthermore, all the support columns are fixed to the hanging basket in a detachable manner.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the protective net is hit, it will buffer the impact force through its own characteristics. The impact force that the protective net cannot absorb and disperse will cause the support frame to move. The support frame will drive all the inner tubes to move, and the inner tubes will guide the protective net to move downward through the cooperation with the outer tube. The support frame will apply force to all buffers during the movement, and the buffers can buffer the impact force received by the support frame. Through two buffers, the impact force received by the hanging basket can be reduced to prevent the hanging basket from shaking drastically or falling directly when it is subjected to excessive impact force, thereby ensuring the life safety of construction workers.

[0014] 2. When objects such as tiles and wall skins fall from the top of the hanging basket, these objects will first contact the tip of the top block. The sharp tip will concentrate the force on a smaller area, thereby breaking the fallen tiles and wall skins. The broken wall skins or tiles will slide or roll along the inclined surface of the baffle and the protective net to prevent the fallen tiles, wall skins or other objects from causing harm to the construction workers in the hanging basket, and to avoid the accumulation of fallen tiles, wall skins and other objects on the baffle or protective net to increase the burden on the lifting mechanism. When the volume of the broken wall skin or tiles becomes smaller, the impact force when falling will also be smaller than before, thereby effectively reducing the damage caused by the wall skin or tiles hitting the outer wall of the building or accidentally hitting the human body.

DETAILED DESCRIPTION

[0022] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0023] Example 1

[0024] The construction protection device for a safety project described in this embodiment is as follows: Figure 1 , Figure 2 and Figure 6 As shown, it includes a baffle 1, and a plurality of support columns 10 for mounting on the hanging basket are vertically fixed at the bottom of the baffle 1. The support columns 10 are steel pipes with a rectangular cross-section structure. Of course, steel pipes with a circular cross-section structure can also be used. The use of steel pipes can effectively reduce the overall weight, thereby reducing the burden on the lifting mechanism;

[0025] The baffle 1 is provided with a plurality of through holes connected to each other from top to bottom, and a transparent plate 9 is fixed in all the through holes to seal them. The transparent plate 9 is made of materials such as organic glass, PC, WR05-PC explosion-proof glass, butadiene transparent impact-resistant resin, etc. The transparent plate 9 is fixed in the through hole by means of glue bonding, screw positioning, etc. When the construction workers need to observe the top of the wall, they can observe the outside through the transparent plate 9, thereby preventing the heads of the construction workers from being exposed to the unprotected area, thereby ensuring the safety of the construction workers;

[0026] All support columns 10 are fixed to the hanging basket in a detachable manner. In this embodiment, one end of all support columns 10 is fixed to the guardrail of the hanging basket by bolts. During installation, through holes for the bolts to pass through are respectively opened on the support columns 10 and the guardrail of the hanging basket, and nuts are set on one end of the bolts passing through the through holes, so that one end of the support column 10 is fixed to the guardrail of the hanging basket; of course, screws can also be used for installation, a through hole for the screw is opened at one end of the support column 10, and a threaded hole threadedly matched with the screw is opened on the guardrail of the hanging basket, so that one end of the support column 10 is fixed to the guardrail of the hanging basket;

[0027] A protective net 3 is arranged above the baffle 1 and is aligned parallel to the baffle 1. The protective net 3 is made of iron or steel and other materials. The protective net 3 and the baffle 1 are aligned parallel to each other at intervals.

[0028] The baffle 1 and the protective net 3 are in a sloping roof shape that is convenient for objects to slide down. In this embodiment, the baffle 1 and the protective net 3 are in a double-slope sloping roof shape. This type of roof is more common in house construction. It has two inclined surfaces, which are inclined to both sides, and usually form a symmetrical structure, so that when tiles, wall skins or other objects fall on the baffle 1 or the protective net 3, these objects can slide or roll down along the inclined surface, thereby preventing the fallen tiles, wall skins or other objects from accumulating on the baffle 1 or the protective net 3, and avoiding adding a burden to the lifting mechanism; of course, the baffle 1 and the protective net 3 can also be in a single-slope sloping roof shape or a four-slope sloping roof shape;

[0029] A support frame 2 for supporting the protective net 3 is fixed along the edge thereof. The edge of the protective net 3 is fixed to the support frame 2 by welding. The support frame 2 is used to support the protective net 3. The protective net 3 is unfolded. Due to its mesh structure, the protective net 3 can disperse the force through multiple nodes when subjected to force, and has a certain flexibility and deformation ability, which enables it to absorb and disperse energy when subjected to impact, thereby playing a buffering role and preventing fallen tiles, wall skins or other objects from causing harm to construction workers;

[0030] A plurality of support rods 5 for supporting the protection net 3 are fixed in the support frame 2. All the support rods 5 are arranged at equal intervals along the length direction of the support frame 2. The support rods 5 are used to support the net body of the middle section of the protection net 3 to prevent the protection net 3 from fitting with the baffle 1 due to its deformation ability before being hit, thereby affecting the buffering effect of the protection net 3 itself;

[0031] A plurality of top blocks 4 for hitting external objects are fixed on all support rods 5, such as Figure 1 , Figure 2 and Figure 3As shown, all top blocks 4 are fixed on the upward side walls of the corresponding support rods 5, and the top blocks 4 are of a conical structure, so that when external objects, such as tiles, wall skins, etc., fall toward the protective net 3, these objects will contact the tip of the top block 4, and the sharp tip will concentrate the force on a smaller area. Since the wall skins or tiles are mostly brittle and easily broken when subjected to impact or pressure, the design of the top block 4 with a conical structure can quickly increase the pressure in the striking area, so that the pressure of the wall skin or tiles exceeds its breaking strength, resulting in the wall skin or tiles breaking. The broken wall skin or tiles slide or roll down along the inclined surface of the protective net 3 or the baffle 1, and the volume of the broken wall skin or tiles becomes smaller, and the impact force when falling will also become smaller than before, thereby effectively reducing the damage caused by the wall skin or tiles hitting the external wall or human body; of course, the top block 4 can also adopt a triangular pyramid, a quadrangular pyramid or the like structure;

[0032] All the top blocks 4 on each support rod 5 are arranged at equal intervals. The neatly arranged top blocks 4 can appear more beautiful and can effectively reduce the probability of collision with falling wall skin or tiles;

[0033] To further explain, Figure 2 , Figure 4 and Figure 6As shown, in this embodiment, it is preferred to include a plurality of inner tubes 15, one end of the inner tube 15 is fixed on the support frame 2, and an outer tube 8 is independently sleeved on each inner tube 15. In this embodiment, the inner tube 15 and the outer tube 8 are round tubes, and of course rectangular tubes can also be used; the inner tube 15 can change the overall length of the combination of the two by moving in the outer tube 8; all inner tubes 15 and the outer tube 8 are vertically arranged, so the inner tube 15 can only move vertically up and down in the outer tube 8; a spring 7 is sleeved on the inner tube 15, and the spring 7 is located between the outer tube 8 and the support frame 2, one end of the spring 7 is in contact with the outer tube 8, and the other end is in contact with the support frame 2. When the spring 7 is in an expanded state, the position of the support frame 2 is Initial state; when the protective net 3 is hit, the protective net 3 will drive all the inner tubes 15 to move downward through the support frame 2, so that the direction of movement of the support frame 2 is guided by the cooperation of the inner tube 15 and the outer tube 8, and at the same time, the support frame 2 will apply pressure to all the springs 7 to shrink all the springs 7. When the impact force disappears, the spring 7 will push the support frame 2 to return to the initial state; one end of all the outer tubes 8 is fixed on the baffle 1, and there are four outer tubes 8, and the four outer tubes 8 are respectively located at the four corners of the baffle 1; a slide groove 13 that communicates with the inside and outside is opened on the tube wall of each outer tube 8, and a threaded hole is opened on the inner tube 15 corresponding to the slide groove 13, and all the slide grooves 13 are equipped with positioning Screws 14, the threaded end of each positioning screw 14 is threadedly matched with the threaded hole at the corresponding position, and the slide groove 13 on each outer tube 8 is opened along the length direction of its tube body, and the length of the slide groove 13 is the distance that the inner tube 15 moves in the outer tube 8; when the support frame 2 is in the initial state, the positioning screw 14 will fit with the top of the slide groove 13, and the blocking of the positioning screw 14 by the slide groove 13 can prevent the inner tube 15 from escaping from the outer tube 8; when the positioning screw 14 fits with the bottom end of the slide groove 13, the blocking of the positioning screw 14 by the slide groove 13 can prevent the inner tube 15 from continuing to move downward, thereby limiting the distance that the support frame 2 moves up and down, and the screws can be disassembled and assembled to be more It is convenient to disassemble and separate the inner tube 15 and the outer tube 8; when in use, when the protective net 3 is hit, the protective net 3 will drive all the inner tubes 15 to move downward through the support frame 2, so that the direction of movement of the support frame 2 is guided by the cooperation of the inner tube 15 and the outer tube 8, and at the same time, the support frame 2 will apply pressure to all the springs 7 to shrink all the springs 7, and the inner tube 15 will drive the positioning screw 14 to slide along the slide groove 13. When the impact force disappears, the spring 7 will push the support frame 2 to return to its initial state, so that the positioning screw 14 will fit with the top of the slide groove 13; this section of the scheme as a whole constitutes a connection component for allowing the support frame 2 to move up and down and limit the moving distance;Of course, the connection assembly can also use four guide rods, one end of which is fixed at the four corners of the bottom of the baffle 1. Corresponding to all the guide rods, the baffle 1 is provided with through holes for the corresponding guide rods to pass independently. Each guide rod is provided with a compression spring, and each guide rod is provided with two screws, which are respectively located at the upper and lower parts of the baffle 1. The distance between the two screws is convenient for the distance for the support frame 2 to move up and down. The guide rod can be disassembled by disassembling the screws. ;

[0034] A plurality of buffers 6 are installed on the baffle 1, and the telescopic ends of all buffers 6 are fixed to the corresponding support rods 5; the buffer 6 is an existing product, and when an object or structure is hit, the buffer can disperse, slow down or convert the impact force into other forms of energy through its specific design and material characteristics, thereby protecting the object or structure from damage or reducing the damage it suffers; in this embodiment, the buffer 6 adopts a hydraulic buffer, and the working principle of the hydraulic buffer is mainly based on the incompressibility of the liquid and the dynamic characteristics of the fluid. When hit or impacted, the piston of the hydraulic buffer will move under pressure, thereby compressing the internal liquid, and the flow of the liquid is restricted. Through a specific damping hole or throttling device, the impact energy is converted into the heat energy and pressure energy of the liquid. This energy conversion process effectively slows down the impact speed and reduces the impact force; the telescopic ends of all buffers 6 are respectively fixed to the support rods 5 aligned with the upper side of the external installation, so that the impact force received by the support frame 2 is buffered by the buffer 6, so as to prevent the hanging basket from shaking or falling directly when it is subjected to excessive impact force; of course, the buffer 6 can also adopt a polyurethane buffer, a hydraulic buffer, a ZL composite buffer, an elastic damping body buffer, etc.

[0035] In actual use, one end of all support columns 10 is fixed to the guardrail of the hanging basket by bolts. When objects such as tiles and wall skins fall from the top of the hanging basket, these objects will first contact the tip of the top block 4, and the sharp tip will concentrate the force on a smaller area, thereby crushing the fallen tiles and wall skins. The broken wall skins or tiles will slide or roll along the inclined surfaces of the baffle 1 and the protective net 3, preventing the fallen tiles, wall skins or other objects from causing harm to the construction workers, and preventing the fallen tiles, wall skins and other objects from accumulating on the baffle 1 or the protective net 3. After the volume of the broken wall skins or tiles becomes smaller, the impact force when falling will also become smaller than before, thereby effectively reducing the damage caused by the wall skins or tiles hitting the outer wall of the building or accidentally hitting the human body; when the protective net 3 is hit, through its own characteristics, it disperses the force through multiple nodes when subjected to force, as well as its flexibility and deformation ability. , which enables it to absorb and disperse energy when impacted, and plays a buffering role. The impact force that the protective net 3 cannot absorb and disperse will cause the support frame 2 to move, and the support frame 2 will drive all the inner tubes 15 to move. The inner tubes 15 will guide the protective net 3 to move downward by cooperating with the outer tube 8. The support frame 2 will apply force to all the buffers 6 during the movement, and the buffers 6 can buffer the impact force received by the support frame 2. Through two bufferings, the impact force received by the hanging basket is reduced to prevent the hanging basket from shaking significantly or falling directly when it is subjected to excessive impact force, thereby ensuring the life safety of the construction workers. The support frame 2 will also apply pressure to all the springs 7 during the movement to shrink all the springs 7, and the inner tubes 15 will drive the positioning screws 14 to slide along the slide groove 13. When the impact force disappears, the springs 7 will push the support frame 2 to return to its initial state, thereby coping with the next impact.
