Description

Technical Field

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

[0002] With the rapid development of engineering construction, the number of employees in the construction industry is increasing, and the complex types of work make safety management at the construction site more difficult. Inadequate safety protection facilities and imperfect safety protection management measures at the construction site can easily lead to safety accidents such as people falling and objects falling.

[0003] At present, a support frame is usually installed outside the building wall, and a protective net is installed on the support frame to deal with situations such as falling people and falling objects. However, the protective net can only provide a good protective effect against falling objects. Due to the large impact force of falling people, the protective effect of the protective net against falling people is poor.

[0004] In response to the above problems, the construction safety protection devices in the prior art often deal with the situation where the impact force of a person falling is large by setting up a multi-layer buffer net or setting an elastic buffer part on the support frame. Although the above two methods can deal with the large impact force generated after a person falls into a construction building, the above two methods will cause a certain upward rebound of the person when the person falls to the last protection net. Since the direction of this upward rebound force is uncontrollable, if the rebound direction is biased toward the outside of the protection net, and the falling person may roll unconsciously toward the outside of the protection net due to fright, it is easy to cause the person to fall again. Summary of the invention

[0005] The present invention proposes a construction safety protection device to solve the deficiencies in the above-mentioned prior art. The construction safety protection device can control the device to buffer the personnel and make the personnel move to the side close to the building wall of the device to avoid secondary falling due to the rebound of the protection net or the subconscious rolling of the personnel.

[0006] The technical solution of the present invention is: a construction safety protection device, which is installed on a building wall, comprises a carrier plate installed on the building wall, and two mounting plates are arranged on the carrier plate in parallel with each other facing the building wall.

[0011] In at least one embodiment of the present invention, a first clamping hook is provided at the bottom end of the second sliding block, a mounting groove is provided at the top end of the connecting block, and the release member includes:

[0012] A second connecting hook is hinged in the mounting groove, and the second connecting hook is hooked with the first connecting hook;

[0013] A transmission shaft is rotatably connected to the mounting groove, a transmission gear is arranged on the transmission shaft, an end of the transmission shaft passes through the mounting groove, and a driven gear is arranged at the passing end;

[0014] A push rod is horizontally slidably connected in the mounting groove, the end of the push rod abuts against the bottom end of the second connecting hook, and is used to push the second connecting hook to deflect so that the first connecting hook and the second connecting hook are disconnected, and the push rod is provided with a first rack meshing with the transmission gear;

[0015] The second rack is longitudinally arranged on the carrier plate, and the second rack is meshed with the driven gear.

[0016] In at least one embodiment of the present invention, both the first connecting hook and the second connecting hook are provided with inclined surfaces abutting against each other, the second connecting hook is provided with a second elastic member, the second elastic member is used to drive the second connecting hook to deflect toward the first connecting hook, and the connecting block is provided with a third elastic member, the third elastic member is used to provide resistance to the downward movement of the connecting block.

[0017] In at least one embodiment of the present invention, a first slide groove is provided on the opposite side of the two mounting plates, and the two first sliding blocks are respectively slidably connected in the first slide groove. Two friction blocks are hinged on the top of the two first sliding blocks, and a friction layer is provided on the side of the two friction blocks close to the inner wall of the first slide groove. A fourth elastic member is provided on the two friction blocks, and the fourth elastic member is used to drive the two friction blocks to deflect toward opposite sides. Limit blocks are provided on the opposite sides of the two friction blocks on the first sliding block, and the limit blocks are used to limit the friction blocks to a vertical state.

[0018] In at least one embodiment of the present invention, when the connecting block is located at the upper limit position, the driven gear is disengaged from the second rack.

[0019] In at least one embodiment of the present invention, when the protection frame moves downward, the resistance of the first elastic member on the first sliding block is equal to the sum of the resistances of the first elastic member and the third elastic member on the second sliding block and the connecting block.

[0020] In at least one embodiment of the present invention, a buffer frame is provided at the top of each of the two mounting plates, and both of the buffer frames are arranged to be inclined downward toward the middle of the carrier plate, and both of the buffer frames are provided with a buffer net.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention is provided with two mounting plates mounted on a carrier plate, a first slider and a second slider slidably connected between the mounting plates, a connecting block clamped on the second slider, a protection frame arranged on the first slider and the connecting block, and a release member for releasing the clamping state of the second slider and the connecting block. When the construction safety protection device is in use, after a person falls, the person falls on the protection net. While the protection net buffers the person, the protection frame drives the first slider, the second slider and the connecting block to move downward in a horizontal state, giving the person the most effective buffering. At this time, the first elastic member connected to the first slider and the second slider can play a secondary buffering role for the protection frame. When the protection frame is moved to the lower limit position by the impact force, due to the action of the first elastic member, the protection frame will rebound upward. When the protection frame rebounds, the clamping of the connecting block and the second slider is released by the release member, and the first slider will move upward under the action of the first elastic member, and finally the protection frame is in an inclined state tilted downward toward the building wall, so that after the person is effectively buffered, due to the inclination of the protection frame, the person moves toward one side of the building wall, avoiding the occurrence of a secondary fall caused by the rebound of the protection net or the subconscious rolling of the person.

[0024] 2. The present invention provides a release member consisting of a second connecting hook, a transmission shaft with a driven gear and a transmission gear, a push rod with a first rack and a second rack. When the protective frame rebounds upward, the second rack arranged on the carrier plate drives the transmission shaft to rotate through the driven gear, and the transmission shaft drives the push rod to move toward the second connecting hook through the transmission gear. The second connecting hook is pushed by the push rod to deflect, so as to quickly release the connection between the second connecting hook and the first connecting hook, thereby making the protective frame quickly tilted. After completing the protection of the personnel, the personnel can quickly move to the device close to the building wall to provide sufficient protection for the personnel.

[0025] 3. The present invention hinges two friction blocks on the first slider and sets two limit blocks on the first slider. When the first slider moves downward, the two friction blocks will be deflected toward the opposite side in stages due to the friction force, so that the friction blocks will not cause excessive friction interference with the downward movement of the first slider. When the first slider moves upward under the action of the first elastic member, the side edges of the friction blocks are always in contact with the inner wall of the first slide groove, thereby always providing friction for the upward movement of the first slider, thereby slowing down the upward movement speed of the first slider and preventing the first slider from rebounding too quickly and causing secondary injury to personnel.

[0026] 4. The present invention provides two buffer frames. When a person falls, he or she will first come into contact with the buffer net on the buffer frame, and the buffer net can be guided to the middle position of the protective net, so that the person can receive the most effective buffering. After the protective frame is inclined, the protective net, the buffer net and the two mounting plates can together form a closed protective space close to the building wall, thereby fully protecting the person before rescue arrives.

[0037] The drawings in the present invention are not drawn strictly according to the actual scale, and the specific size and quantity of each structure can be determined according to actual needs. The drawings described in the present invention are only schematic diagrams of the structures.

[0038] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. The words "include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Inside", "outside", "up", "down", "far", "near", "front", "back" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0040] In response to the problem raised by the present invention that people may easily fall for a second time due to the rebound of the protection frame or the subconscious rolling of the people due to being frightened or for self-protection reasons, there is also a solution in the prior art that is to directly set a protection net on the building wall that is inclined downward toward the building wall to solve this problem. However, if the protection net is directly designed to be inclined, the impact force on the protection net is not perpendicular to the net surface, thereby sacrificing the impact resistance of the protection net. It may also cause people to slide directly towards the building wall with a large impact force, causing secondary injuries.

[0041] The invention provides a construction safety protection device, wherein the protection net can provide the most effective buffer for personnel.

[0042] Combination Figures 1 to 8 As shown, a construction safety protection device is installed on a building wall 1, including a carrier plate 2 installed on the building wall 1, characterized in that two mounting plates 21 are arranged on the carrier plate 2 in parallel with each other toward the building wall 1, and the two mounting plates 21 are perpendicular to the carrier plate 2. The construction safety protection device also includes:

[0043] The sliding member includes two first sliders 3 and two second sliders 4. The two first sliders 3 are respectively connected to the opposite sides of the two mounting plates 21 by longitudinal sliding. The two second sliders 4 are respectively connected to the opposite sides of the two mounting plates 21 by longitudinal sliding. The two second sliders 4 are located on the side of the two first sliders 3 close to the building wall 1. The two first sliders 3 and the two second sliders 4 are both provided with a first elastic member, which is used to provide resistance to the downward movement of the first slider 3 and the two second sliders 4. Specifically, the first elastic member is a spring.

[0044] The two connecting blocks 5 are respectively clamped on the two second sliding blocks 4, and connecting columns are provided on opposite sides of the two connecting blocks 5;

[0045] The protection frame 6 is arranged between the two mounting plates 21. The sides of the protection frame 6 are provided with connectors respectively rotatably connected to the two first sliders 3 and strip holes respectively for two connecting columns to penetrate. A protection net is installed on the protection frame 6. In the initial state, the protection frame 6 is horizontal. The horizontal protection net can achieve the best protection effect.

[0046] The two releasing members 7 are respectively arranged on the two connecting blocks 5, and are used to release the connection block 5 when the connecting block 5 rebounds upward, so as to release the clamping connection between the connecting block 5 and the second slider 4, so that the protective frame 6 is in an inclined state tilted downward toward the building wall 1; specifically, in addition to the following form, the releasing member 7 can also adopt two docking rings on the connecting block 5 and the second slider 4, and a push-pull electromagnet is arranged on the connecting block 5 or the second slider 4, the movable rod of the push-pull electromagnet is arranged in the two docking rings, and a displacement sensor for detecting the movement of the protective frame 6 is arranged on the carrier plate 2, and the movable rod of the push-pull electromagnet is controlled to retract by electric control during the upward rebound of the carrier plate 2 to release the clamping connection between the connecting block 5 and the second slider 4, but the above-mentioned form of releasing member 7 needs to be configured with special electric control components and control system, which leads to high cost of the device and inconvenience in layout. The following purely mechanical structure releasing member 7 has high reliability, low cost and is easy to layout.

[0047] As an alternative embodiment, the bottom end of the second sliding block 4 is provided with a first clamping hook 41, the top end of the connecting block 5 is provided with a mounting groove 51, and the release member 7 includes:

[0048] A second connecting hook 71 is hinged in the mounting groove 51, and the second connecting hook 71 is hooked with the first connecting hook 41;

[0049] The transmission shaft 72 is rotatably connected to the mounting groove 51. The transmission shaft 72 is provided with a transmission gear 721. The end of the transmission shaft 72 passes through the mounting groove 51, and the end thereof is provided with a driven gear 722.

[0050] A push rod 73 is horizontally slidably connected in the mounting groove 51, and the end of the push rod 73 abuts against the bottom end of the second connecting hook 71, and is used to push the second connecting hook 71 to deflect, so that the first connecting hook 41 and the second connecting hook 71 are disconnected, and a first rack meshing with the transmission gear 721 is provided on the push rod 73;

[0051] The second rack 74 is longitudinally disposed on the carrier plate 2 , and the second rack 74 is meshed with the driven gear 722 .

[0052] As an alternative embodiment, the two first connecting hooks 41 and the second connecting hook 71 are both provided with inclined surfaces abutting against each other, and the second connecting hook 71 is provided with a second elastic member, and the second elastic member is used to drive the second connecting hook 71 to deflect toward the first connecting hook 41. The second elastic member is a torsion spring arranged at the second connecting hook 71, and a third elastic member is provided on the connecting block 5, and the third elastic member is used to provide resistance to the downward movement of the connecting block 5; the elastic force of the third elastic member is relatively small, and its elastic force can only push the protective frame 6 back to the initial state.

[0053] As an alternative embodiment, a first slide groove 211 is provided on the opposite side of the two mounting plates 21, and the two first sliding blocks 3 are slidably connected in the first slide groove 211 respectively. The top ends of the two first sliding blocks 3 are hinged with two friction blocks 31. The two friction blocks 31 are provided with a friction layer on the side of the inner wall close to the first slide groove 211, and the friction layer abuts against the inner wall of the first slide groove 211. A fourth elastic member is provided on the two friction blocks 31, and the fourth elastic member is used to drive the two friction blocks 31 to deflect toward the opposite side. The fourth elastic member is a torsion spring, and the fourth elastic member is arranged at the hinge of the friction block 31 and the first sliding block 3. A limit block 32 is provided on the opposite side of the two friction blocks 31 of the first sliding block 3, and the limit block 32 is used to limit the friction block 31 to a vertical state; when the first sliding block 3 moves downward, the two friction blocks 31 will be deflected toward the opposite side in stages by the friction force, so that the friction blocks 31 will not interfere with the downward movement of the first sliding block 3 too much friction force, and When the slider 3 is moved upward by the force of the first elastic member, the side of the friction block 31 is always in contact with the inner wall of the first slide groove 211, thereby always providing friction for the upward movement of the first slider 3, thereby slowing down the upward movement of the first slider 3. At this time, the limit block 32 can make the friction block 31 and the inner wall of the first slide groove 211 in a state of parallel contact with each other, and the friction force generated by the friction block 31 is moderate, and the upward movement of the first slider 3 will not cause the friction block 31 to excessively abut against the inner wall of the first slide groove 211, thereby generating excessive friction, so that the first slider 3 can be smoothly raised to the upper limit position by the force of the first elastic member; the setting of the friction block 31 can prevent the protection frame 6 from being affected by the first elastic member and rebounding too fast to interfere with the movement of the personnel thereon during the rescue process; at the same time, it can prevent the falling objects from being affected by the tilt of the protection frame 6 and moving toward the slag collecting box 9. The protection frame 6 rebounds too fast to cause the falling objects to splash.

[0054] As an alternative embodiment, when the connecting block 5 is located at the upper limit position, the driven gear 722 disengages from the second rack 74, so that the second rack 74 and the push rod 73 do not interfere with the deflection of the second connecting hook 71; the first connecting hook 41 and the second connecting hook 71 can be re-connected under the action of the inclined surface and the second elastic member.

[0055] As an alternative embodiment, when the protective frame 6 moves downward, the resistance of the first elastic member on the first slider 3 is equal to the sum of the resistances of the first elastic member and the third elastic member on the second slider 4 and the connecting block 5, so that when the protective frame 6 is subjected to a downward impact force, it can move downward in a horizontal state, thereby providing the best protective effect for personnel on the protective net.

[0056] As an alternative embodiment, a buffer frame 212 is provided at the top of each of the two mounting plates 21, and the two buffer frames 212 are inclined downward toward the middle position of the carrier plate 2, and a buffer net is provided on each of the two buffer frames 212; a rotating shaft is provided at the top of each of the two mounting plates 21, and the two buffer frames 212 are respectively arranged on two rotating shafts, and the two rotating shafts are provided with a torsion spring connected to the mounting plates 21, and the torsion spring is used to provide resistance to the deflection of the buffer frame 212 toward between the two mounting plates 21; specifically, the torsion spring abuts against the buffer frame 212, and only provides resistance to the deflection of the buffer frame 212 toward between the two mounting plates 21, and when the buffer frame 212 deflects in a direction away from between the two mounting plates 21, the torsion spring does not provide resistance, so that when personnel are rescued from the protective device, the personnel can push the buffer frame 212 out of the device.

[0057] As an alternative embodiment, the length of the protective frame 6 perpendicular to the building wall 1 is greater than the length of the mounting plate 21, and the two buffer frames 212 are both U-shaped frames. The openings of the two buffer frames 212 are relatively connected to two rotating shafts respectively, and the open ends of the two U-shaped buffer frames 212 are relatively arranged. Since the buffer frames 212 are U-shaped, there are no support rods in their relative positions, thereby preventing this part of the support rods from causing harm to personnel in the process of buffering personnel; the upper surface and end of the buffer frame 212 are provided with a rubber protective layer, which can prevent the buffer frame 212 from causing harm to personnel when the personnel come into contact with the buffer frame 212.

[0058] As an alternative embodiment, a connecting plate 22 perpendicular to the carrier plate 2 is provided on one side of the two carrier plates 2 close to the building wall 1, and the connecting plate 22 is used to be connected to the building wall 1; specifically, the connecting plate 22 is fixedly connected to the building wall 1 using multiple expansion anchors, and a reinforcing rib connected to the connecting plate 22 is provided at the bottom of the carrier plate 2; the setting of the reinforcing rib can ensure that the carrier plate 2 has considerable structural strength to cope with the impact force transmitted by falling objects or people during work.

[0059] As an alternative embodiment, a slag box 9 is provided between the two mounting plates 21 on the carrier plate 2 near the building wall 1. The slag box 9 is used to collect fallen objects so as to centrally process the fallen objects and impurities in the slag box 9 during device maintenance. The slag box 9 is located below one side of the protective frame 6. The inner cavity length of the slag box 9 is equal to the width of the protective frame 6. This limitation enables all fallen objects on the protective net to fall into the slag box 9 during the tilting of the protective frame 6, so that all fallen objects in the protective frame 6 can be collected in the slag box 9. A card slot is provided on the carrier plate 2, and the slag box 9 can be detachably connected to the card slot. The card slot is set to limit the position of the slag box 9 and facilitate centralized processing of the slag box 9.

[0060] The working principle and usage of this embodiment:

[0061] The present invention provides a construction safety protection device. When the construction safety protection device is in use, if a person falls, the person first contacts the buffer net, and the buffer net will buffer the person for the first time. At the same time, if the person falls to the edges of the two buffer nets, the buffer net can guide the person to the middle of the protection net where the protection effect is best. When the person impacts the protection net, the protection net buffers the person, and the protection frame 6 drives the first slider 3, the second slider 4 and the connecting block 5 to move downward together. At this time, the first elastic member connected to the first slider 3 and the second slider 4 and the third elastic member connected to the connecting block 5 can play a role in buffering the protection frame 6 again. When the protection frame 6 is moved to the lower limit position by the impact force, due to the action of the first elastic member and the third elastic member, the protection frame 6 will rebound upward. In the process of rebounding upward, the second rack 74 arranged on the carrier plate 2 drives the transmission shaft 72 to move forward through the driven gear 722. The second connecting hook 71 is pushed to deflect by the pushing rod 73 to release the connection between the second connecting hook 71 and the first connecting hook 41, so that the connecting block 5 is disconnected from the second slider 4. Since the elastic force of the third elastic member is relatively small, the connecting block 5 will not rebound upward when the personnel give pressure to the protection frame 6. At the same time, the first slider 3 also rebounds upward at a slower speed under the action of the friction block 31 and the first elastic member, so that the protection frame 6 is inclined downward toward the building wall 1, so that the personnel are closer to the building wall 1. At the same time, under the protection of the first buffer frame 212, the construction personnel are fully protected before the rescue arrives to avoid a secondary fall. When the personnel are in the protection space, the buffer net above the personnel can also protect the falling objects that fall with the personnel to avoid injuries to the personnel.

[0062] When the device faces daily falling objects from high altitude, the buffer net will first come into contact with the falling objects and perform the first buffering on the falling objects. As in the above principle, the falling objects are guided by the buffer net and finally fall onto the protective net, and the protective frame 6 moves downward, and then a small amount of rebound occurs, so that the connecting block 5 is disengaged from the second slider 4, and the protective frame 6 is tilted to allow the falling objects to slide into the slag collecting box 9.

[0063] After the above-mentioned personnel complete the rescue or the fallen objects fall into the slag collecting box 9, the connecting block 5 moves upward under the action of the third elastic member, and the second connecting hook 71 re-contacts the first connecting hook 41, and under the action of the second connecting hook 71 and the inclined surface of the first connecting hook 41, the second connecting hook 71 re-hooks with the first connecting hook 41, so that the device can automatically reset to the initial state.

[0064] The above embodiments are only specific implementation methods of the patent of the present invention, which are used to illustrate the technical solution of the patent of the present invention rather than to limit it. The protection scope of the patent of the present invention is not limited thereto. Although the patent of the present invention is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the above embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution for implementing the patent of the present invention, and should be covered within the protection scope of the present invention.
