Description

Technical Field

[0001] The present invention relates to the technical field of construction safety, and in particular to a construction safety protection device at a capital construction site. Background Art

[0002] Hospital infrastructure projects are an important part of hospital construction and development. They involve multiple links such as land planning, overall functional layout design, construction and installation, and are professional and demanding. In hospital infrastructure projects, construction safety and personnel protection issues are becoming increasingly important. With the increase in building height and the complexity of the construction environment, falling objects from high altitudes have become one of the main safety hazards at construction sites. Traditional safety protection measures, such as setting up safety nets and installing guardrails, have played a protective role to a certain extent, but when faced with heavy or irregularly shaped construction waste falling, their protective effects are often limited, and it is difficult to completely avoid injuries to construction workers below. In order to more effectively deal with the risk of falling objects from high altitudes, some improved safety protection devices have emerged.

[0003] The "A safety protection device for construction site of infrastructure projects" provided by Chinese patent authorization announcement number CN215631863U can be used in conjunction with a telescopic rod and a universal wheel, so that the protection device can be moved as a whole without disassembly when it needs to be moved, thereby improving work efficiency. At the same time, a two-level protection structure is set up, that is, a protection net is used to block falling objects from high altitudes. When the weight of the falling object exceeds the limit that the protection net can bear and passes through the protection net and falls, the buffer plate will resist the heavy object and play a protective role, and the elastic part will offset the impact force of the falling object.

[0004] The following defects are not noted in the above patents:

[0005] Although the protective net can block some falling objects from high altitude, when the weight of the falling objects exceeds the bearing limit of the protective net, the falling objects will pass through the protective net and continue to fall. This means that there is an upper limit to the protective capacity of the protective net, and it may not provide effective protection for heavy or large construction waste. Although the buffer plate can withstand the falling objects passing through the protective net and offset part of the impact force through elastic parts, this buffering method is relatively simple and lacks multiple buffering mechanisms. When facing high-speed, heavy or irregularly shaped falling objects, the protective effect of the buffer plate may not be ideal; moreover, when the falling objects pass through the protective net and fall on the buffer plate, if the buffering effect is not good, the falling objects may rebound or splash, causing secondary injuries to the surrounding construction workers. In addition, if the buffer plate is improperly designed or aged and damaged, it may also cause the falling objects to directly hit the ground or construction workers.

[0006] Based on the above background, the present invention proposes an innovative safety protection device for on-site construction of hospital infrastructure projects. The device achieves effective protection against falling objects from high altitudes through a clever combination of multiple buffer unloading structures and blocking structures, thereby greatly improving the safety of the construction site.

[0032] Specifically, when construction workers need to carry out construction work under the construction building, they need to install safety protection devices on the construction site for protection. When falling objects appear, the falling construction waste will fall on the protective load-bearing plate 31, and the downward impact force of the construction waste will be buffered and unloaded through the rubber seat 61 on the supporting buffer structure 6. At the same time, under the action of the impact force, the top plate 2 squeezes the multiple buffer springs 21 downward to store force, thereby realizing secondary buffer unloading. When the construction waste falls between one or two assembly plates 31, since the lower part of each assembly plate 31 is rotatably connected through the supporting buffer structure 6, The impacted assembly plate 31 will be caused to tilt toward the adjacent hinge, thereby driving the other assembly plate 31 to follow the tilt. One of the assembly plates 31 is assisted in buffering by the connected adjustment buffer structure 7 to reduce the impact. The hinges of the two assembly plates 31 are downwardly contacted and squeezed with the auxiliary buffer structure 8 to assist in buffering again, reducing the impact force to a minimum. At the same time, the assembly plates 31 on both sides are tilted to intercept the construction waste on the left and right sides, and the top of the safety protection device is tilted. The front of the assembly plate 31 is higher, which can achieve front interception, effectively preventing construction waste from bouncing off from both sides and causing secondary flying injuries, thereby improving safety.

[0033] The support frame 1 is fixed to the ground by bolts of the base 11 or inserted and fixed to the ground by threaded ground plugs 12, so that the support stability of the safety protection device is high after installation.

[0034] Among them, the two supporting buffer structures 6 on the left and right edges of the connecting plate 5 are higher than the other multiple supporting buffer structures 6, and the assembly plates 31 on both sides of the installed connection are inclined. The assembly 31 on both sides of the rotating device is inclined toward the center, so that falling objects from high altitude can move toward the middle for buffering after being hit.

[0035] In this embodiment, Figure 6It is shown that the support buffer structure 6 includes a rubber seat 61 fixed on the connecting plate 5 and a connecting head 63 fixed on the bottom of the assembly plate 31, a support column 62 is fixed on the top of the rubber seat 61, a connecting groove 64 is opened on the top of the support column 62, and the connecting head 63 is inserted into the connecting groove 64 for rotation shaft connection.

[0036] Specifically, the downward impact force of the construction waste is buffered and unloaded through the rubber seat 61 on the support buffer structure 6, which is rotatably connected to the support column 62 through the connecting head 63, thereby causing the impacted assembly plate 31 to tilt toward the adjacent hinge, thereby driving the other assembly plate 31 to follow the tilt, and one of the assembly plates 31 is assisted in buffering by the connected adjustment buffer structure 7.

[0037] The assembly plate 31 is a thickened polycarbonate plate with high impact resistance.

[0038] In this embodiment, Figure 8 It is given that the adjustment buffer structure 7 includes a mounting plate 71 fixed on the top of the connecting plate 5 and a mounting head 76 fixed on the top of the assembly plate 31, buffer modules are fixed on both sides of the top of the mounting plate 71, and a connecting shaft 73 is rotatably connected between the two buffer modules. A steel wire rope 75 is wound on the outside of the connecting shaft 73, one end of the steel wire rope 75 is fixed to the connecting shaft 73, and the other end is fixedly connected to the mounting head 76.

[0039] Specifically, when the assembly plate 31 is impacted and tilted, the steel wire rope 75 is pulled, and the steel wire rope 75 pulls the connecting shaft 73 to unwind, driving the two buffer modules to buffer, thereby improving safety.

[0040] Among them, the buffer module includes a shell 72, a connecting shaft 73 passes through the shell 72 and is rotatably connected through a bearing. Inside the shell 72, a volute spring 74 is sleeved on the outside of the connecting shaft 73. One end of the volute spring 74 is fixed to the connecting shaft 73, and the other end is fixed to the shell 72.

[0041] Specifically, when the assembly plate 31 is impacted and tilted, the wire rope 75 is pulled, and the wire rope 75 pulls the connecting shaft 73 to unwind, driving the connecting shaft 73 to rotate and drive the two volute springs 74 to contract and store force. The elasticity of the volute springs 74 reduces the impact force and improves safety.

[0042] Embodiment 2, on the basis of embodiment 1, an auxiliary buffer structure 8 is fixed on the top of the connecting plate 5 below the hinge of every two assembly plates 31, the auxiliary buffer structure 8 includes a buffer plate 81, a plurality of buffer springs 82 are fixed to the bottom of the buffer plate 81, the plurality of buffer springs 82 are fixedly connected to the connecting plate 5, and the buffer plate 81 is located below the hinge of the two assembly plates 31.

[0043] Specifically, the two assembly plates 31 are stressed so that the hinged parts are pressed downwardly against the buffer plate 81 , and the buffer plate 81 squeezes and stores the multiple buffer springs 82 , thereby reducing the impact force.

[0044] Embodiment 3, based on embodiment 1, Figure 7 It is shown that a plurality of blocking structures 4 are evenly fixed on the upper and lower rear parts of the support frame 1, and the blocking structures 4 include connecting frames 43 fixed on both sides of the rear part of the support frame 1, a plurality of buffer ropes 42 are fixedly connected between the two connecting frames 43, and a secondary support rod 41 is fixed in the middle of the two connecting frames 43 and is fixedly connected to the support frame 1, and the plurality of blocking structures 4 are located in the inclined low position direction of the protective load-bearing plate 3, and the plurality of blocking structures 4 cooperate with the protective load-bearing plate 3 for buffering.

[0045] Specifically, since the device is inclined, the construction waste slides down and falls to a low position, and the impact is reduced by multiple blocking structures 4. Multiple buffer ropes 42 are distributed in parallel on each blocking structure 4. The construction waste falls onto the multiple buffer ropes 42 to reduce the impact force of the material, and the buffer ropes 42 are stretched to fall from the gap to the multiple buffer ropes 42 of the next blocking structure 4 for buffering, reducing the impact connections one by one, so that it can land safely, thereby greatly improving safety.

[0046] Working principle:

[0047] When construction workers need to perform construction work under the construction building, safety protection devices need to be installed at the construction site for protection. The support frame 1 is fixed to the ground through the base 11 bolts or nailed into the ground through the ground plug 12 to protect the construction workers. When falling objects appear, the falling construction waste falls on the protective load-bearing plate 31, and the downward impact force of the construction waste is buffered and unloaded through the rubber seat 61 on the support buffer structure 6. At the same time, under the action of the impact force, the top plate 2 squeezes the multiple buffer springs 21 downward to store force, thereby realizing secondary buffer unloading;

[0048] Moreover, the protective load-bearing plate 31 is composed of a plurality of assembly plates 31 of thick polycarbonate plates that are hinged together. When construction waste falls between one or two assembly plates 31, since the lower part of each assembly plate 31 is connected by a supporting buffer structure 6, that is, it is rotatably connected to the support column 62 through a connecting head 63, the impacted assembly plate 31 will be tilted toward the adjacent hinge, thereby driving the other assembly plate 31 to follow the tilt. One of the assembly plates 31 is assisted in buffering by the connected adjustment buffer structure 7 to reduce the impact. The hinges of the two assembly plates 31 are downwardly contacted and squeezed with the auxiliary buffer structure 8 to assist in buffering again, reducing the impact force to a minimum. At the same time, the assembly plates 31 on both sides are tilted to intercept the construction waste in the left and right directions, and the top of the safety protection device is tilted. The front part of the assembly plate 31 is higher, which can achieve front interception, effectively preventing the construction waste from bouncing off from both sides and causing secondary flying injuries, thereby improving safety.

[0049] When the assembly plate 31 is impacted and tilted, the wire rope 75 is pulled, and the wire rope 75 pulls the connecting shaft 73 to unwind, driving the two buffer modules to buffer, that is, the connecting shaft 73 rotates to drive the volute spring 74 to contract and store force, and the elasticity of the volute spring 74 reduces the impact force, thereby improving safety;

[0050] When the two assembly plates 31 are stressed so that the hinged part contacts and squeezes downward with the buffer plate 81, the buffer plate 81 squeezes and stores the multiple buffer springs 82, and the impact force is reduced by the multiple buffer springs 82;

[0051] Therefore, the impact force of the falling construction waste is reduced through multiple buffer unloading forces, so that the construction workers are protected. After the buffer spring 1 21, the buffer spring 2 82 and the auxiliary buffer structure 8 return to their positions, the device is inclined, so that the construction waste slides down and falls to a low position, and the impact is reduced by multiple blocking structures 4. Multiple buffer ropes 42 are distributed in parallel on each blocking structure 4. The construction waste falls onto the multiple buffer ropes 42 to be blocked and reduce the impact force of the material discharge, and the buffer ropes 42 are stretched to fall from the gap to the multiple buffer ropes 42 of the next blocking structure 4 for buffering, reducing the impact connections one by one, so that it can land safely, greatly improving safety.
