However, the patent still has the problem that holding the pull ring affects the normal operation and work efficiency of the workers. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a safety protection device for housing construction installation engineering, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a safety protection device for housing construction installation engineering, comprising a support truss, a truss shift seat is slidably connected to the rear side of the support truss, a mounting stand is fixedly connected to the rear side of the truss shift seat, a track beam is fixedly connected to the top of the mounting stand, a stand structure is arranged above the track beam, an anti-fall structure is installed on the top of the stand structure, an extension structure is arranged on the bottom surface of the stand structure, and a locking structure is arranged on the side of the stand structure;

[0006] The platform structure includes a platform, the top surface of the platform is fixedly connected to four vertical frame rods, the outer sides of the four vertical frame rods are fixedly connected to two protective grilles, the top ends of the four vertical frame rods are fixedly connected to a handrail frame, the anti-fall structure includes a joint end shell, the joint end shell is arranged on the top surface of the handrail frame, the outer side of the joint end shell is rotatably connected to an end shell connecting seat, the bottom end of the end shell connecting seat is fixedly connected to a sliding groove ball rod, a limited groove rod ring is arranged inside the handrail frame, a thin square rod is slidably connected inside each of the vertical frame rods, a belt threading groove is provided on the top side of the joint end shell, and the inner rotation of the joint end shell is fixedly connected to the sliding groove ball rod. The cam is provided with a plurality of locking plates, the locking plates having two locking plates and a plurality of locking plates, the plurality of locking plates having two locking plates and a plurality of locking plates respectively securing the plurality of locking plates to a plurality of locking plates. A spring is provided on one side of the wheel, and both ends of the spring are fixedly connected to the take-up wheel and the connected end shell respectively. The worker needs to stand on the platform and tie the belt around his waist. When the worker moves on the platform, the belt pulls the connected end shell to move through the connected safety belt, so that the connected end shell slides along the limited groove rod ring and the top side of the handrail through the slide groove ball rod connected to the end shell seat. When the worker moves, the safety belt on the take-up wheel will be released through the belt. The rotation of the take-up wheel will cause the spring to torsion spring. When the worker approaches the connected end shell, the spring resets to cause the take-up wheel to rotate and reel in the safety belt. When the worker stands on the platform close to the handrail to perform structural work on the building During installation, the worker's waist is restrained by a safety belt to prevent the worker from falling outside the table top and to prevent the worker from slipping and falling due to the shaking of the table top and the connected structure, thus playing a role of safety protection. At the same time, when the worker accidentally falls outside the table top, the waist belt falls due to gravity and pulls the safety belt, allowing the safety belt to pull the connecting end shell to deflect downward around the connection between the end shell and the seat. At this time, the counterweight block in the connecting end shell moves to the top, and the counterweight block pushes the locking rod to slide along the rod seat under the action of gravity, so that the end of the locking rod is stuck in the ratchet, preventing the ratchet from continuing to rotate to release the safety belt, allowing the worker's body to grasp the side structure of the table top.

[0007] The cam frame is an axially rotatable plate that is fixedly connected to the bottom end of the slender square rod, and the cam frame is an axially rotatable plate that is fixedly connected to the bottom end of the slender square rod. The cam frame is an axially rotatable plate that is fixedly connected to the bottom end of the slender square rod. The cam frame is an axially rotatable plate that is fixedly connected to the bottom end of the slender square rod. The cam frame is an axially rotatable plate that is fixedly connected to the bottom end of the slender square rod. The cam is connected to the top of the cam by a spring, and the cam is connected to the bottom of the cam by two springs, and the cam is connected to the bottom of the cam by two springs. The side extension plate is slidably connected to the table plate, and the slide plate frame rod is slidably connected to the extension plate slide seat. When the connected end shell pulls the slide groove ball rod through the connected end shell connecting seat, the slide groove ball rod squeezes the limit groove rod ring downward, so that the limit groove rod ring squeezes the elastic spring under pressure and pushes the thin square rod downward to push the blocking block. The blocking block is separated from the blocking groove on the side of the extension plate frame rod. At this time, the extension plate frame rod is no longer bound, and the return spring outside the elastic beam rod begins to contract and pulls the elastic beam rod to move upward. The hinge rod connected to the elastic beam rod is pulled, so that the hinge rod pushes the two connecting rod frames away from each other, and the connecting rod frame movement belt The dynamically connected extension plate extends from the bottom surface of the table top, and the extension plate slides along the skateboard frame rod through the extension plate slide to provide support. The table top area is increased by extending the extension plate, providing leg standing space for workers, and preventing workers from leaning their bodies out and causing the center of gravity to go down and fall. At the same time, when the connecting rod frame moves, the connecting rod frame will drive the slide folding rod to move, so that the end of the slide folding rod slides along the inclined slot rod, so that the inclined slot rod is subjected to force and drives the connected side extension plate to extend outward from the table top, so that the side extension plate or extension plate at the extension can provide support for the worker's arm after the worker falls.

[0008] According to the above technical scheme, the locking structure includes a locking link, the locking link is arranged under the hinge rod, the two ends of the locking link are slidably connected with a locking frame, both sides of the locking frame are fixedly connected with two locking blocks, the four corners of the bottom surface of the table plate are fixedly connected with a slide rail seat, the bottom surface of the track beam rod is fixedly connected with a limited groove bar, the bottom ends of the two sides of the locking frame are fixedly connected with a side seat rod, the side of the side seat rod away from the locking frame and the rear side of the locking frame are fixedly connected with a buffer rubber block, the locking link is fixedly connected to the elastic beam rod, the slide rail seat is slidably connected to the track beam rod, the locking frame and the slide rail seat are fixedly connected, and when the elastic beam rod moves upward along the table plate, the elastic beam rod pulls The connected locking link moves, causing the locking link to slide upward with the locking frame. After the locking link contacts the locking frame, it will push the locking frame to slide along the slide rail seat again, and allow the locking block connected to the side of the locking frame to fit with the limiting groove strip at the corresponding position of the bottom surface of the track beam, thereby fixing the table plate and the track beam rod, preventing the slide rail seat from moving to the specified position on the track beam rod driven by an external motor, and preventing the worker from walking above the table plate to generate vibration, causing the slide rail seat and the track beam rod to move under the action of vibration. The slide rail seat is implemented as an existing technology using an electric drive wheel drive and a remote control terminal control. The limiting groove strip fits with the locking block to prevent the slide rail seat from being displaced by the vibration and causing the worker to fall during installation work, thereby improving the stability of the table plate structure support.

The middle part of the platform 51 is slidably connected to an elastic beam rod 77. The bottom end of the elastic beam rod 77 is hingedly connected to four hinge rods 76. Each connecting rod frame The left and right ends of the frame 75 are fixedly connected with a slide folding rod 78, and the end of the slide folding rod 78 away from the connecting rod frame 75 is slidably connected with an inclined groove rod 79, and the top surface of the inclined groove rod 79 is fixedly connected with a side extension plate 710, and the bottom surface of each extension plate 74 is fixedly connected with two extension plate slide seats 712, and the bottom surface of the table 51 is fixedly connected with two slide plate frame rods 711. The bottom surface of the bottom frame 72 is provided with a card slot, and the card slot is adapted to the card block 71 structure. The four hinge rods 76 are grouped in pairs, and each group of hinge rods 76 is away from the elastic One end of the force beam rod 77 is hingedly connected to the connecting rod frame 75, a return spring is arranged on the outer side of the elastic beam rod 77, and the two ends of the return spring are respectively fixedly connected to the table 51 and the elastic beam rod 77, the side extension plate 710 is slidably connected to the table 51, the slide plate frame rod 711 is slidably connected to the extension plate slide seat 712, and the extension plate 74 is extended to increase the area of ​​the table 51, providing leg standing space for the worker to prevent the worker from leaning his body out and causing the center of gravity to fall downward. At the same time, when the connecting rod frame 75 moves, the connecting rod frame 75 will drive the slide folding rod 78 to move, so that the end of the slide folding rod 78 slides along the inclined slot rod 79, so that the inclined slot rod 79 drives the connected side extension plate 710 to extend outward from the platform 51 after being subjected to force, so that the side extension plate 710 or the extension plate 74 at the extension can provide support for the worker's arm after the worker falls, so that during subsequent rescue, the worker's arm can climb upward with the side extension plate 710 or the extension plate 74 as support, and by increasing the standing space, the worker's body is prevented from being stretched out, thereby improving the safety of the worker during installation operations.

[0025] The locking structure 8 includes a locking link 81, which is arranged below the hinge rod 76. The two ends of the locking link 81 are slidably connected to a locking frame 82. Two locking blocks 83 are fixedly connected to both sides of the locking frame 82. The four corners of the bottom surface of the table 51 are fixedly connected to a slide rail seat 84. The bottom surface of the track beam 4 is fixedly connected to a limited groove bar 85. The bottom ends of both sides of the locking frame 82 are fixedly connected to a side seat rod 86. The side of the side seat rod 86 away from the locking frame 82 and the rear side of the locking frame 82 are fixedly connected to a buffer rubber block 87. The locking link 81 is fixedly connected to the elastic beam rod 77, the slide rail seat 84 is slidably connected to the track beam rod 4, the locking frame 82 and the slide rail seat 84 are fixedly connected, and the limiting groove strip 85 is engaged with the locking block 83 to prevent the slide rail seat 84 from being displaced by vibration and causing the worker to fall during the installation operation, thereby improving the stability of the structural support of the platform 51. At the same time, the buffer rubber block 87 connected to the side of the side seat rod 86 can buffer the worker's body after the worker falls, thereby preventing the worker from falling and being hit by the installation platform 3 and causing physical injury.

[0026] Working principle: the worker needs to stand on the platform 51 and tie the belt 613 around his waist. When the worker moves on the platform 51, the belt 613 pulls the connected end shell 61 through the connected safety belt 612, so that the connected end shell 61 is connected to the slide ball rod 63 through the end shell connecting seat 62 and slides along the limit groove rod ring 64 and the top side of the handrail frame 53. The worker's movement will pull the safety belt 612 on the winding wheel 67 through the belt 613 to release, and the rotation of the winding wheel 67 will cause the spring torsion spring. When the worker approaches the connected end shell 61, the spring resets to cause the winding wheel 67 to rotate and reel up the safety belt 612. When the worker stands on the platform 51 and approaches the handrail frame 53 to install the building structure, the worker's waist is restrained by the safety belt 612 to prevent the worker from falling onto the platform. The outer side of the plate 51 is prevented from slipping and falling due to the shaking of the platform 51 and the connected structure, which plays a role in safety protection. At the same time, when the worker accidentally falls outside the platform 51, the waist belt 613 falls under the gravity and pulls the safety belt 612, so that the safety belt 612 pulls the connected end shell 61 to deflect downward around the connection between the end shell and the seat 62. At this time, the counterweight block 610 in the connected end shell 61 moves upward, and the counterweight block 610 pushes the locking rod 69 to slide along the rod seat 611 under the action of gravity, so that the end of the locking rod 69 is stuck on the ratchet 68, preventing the ratchet 68 from continuing to rotate to release the safety belt 612, so that the worker's body can grasp the side structure of the platform 51, avoiding the worker from hanging in the air after falling, causing excessive physical consumption and affecting subsequent rescue, thereby improving the safety protection effect;

[0027] When the associated end shell 61 pulls the slide groove ball rod 63 through the connected end shell connecting seat 62, the slide groove ball rod 63 squeezes the limit groove rod ring 64 downward, so that the limit groove rod ring 64 squeezes the elastic spring and is compressed and pushes the thin square rod 65 to push the blocking block 71 downward. The blocking block 71 disengages from the blocking groove on the side of the extension plate frame rod 73. At this time, the extension plate frame rod 73 is no longer restrained, and the return spring on the outer side of the elastic beam rod 77 begins to contract and pulls the elastic beam rod 77 to move upward. The hinge rod 76 connected to the elastic beam rod 77 is pulled, so that the hinge rod 76 pushes the two connecting rod frames 75 away from each other. The movement of the connecting rod frame 75 drives the connected extension plate 74 to extend from the bottom surface of the platform 51, and allows the extension plate 74 to slide along the slide plate frame rod 711 through the extension plate slide seat 712 to provide The extension plate 74 is extended to increase the area of ​​the platform 51, providing leg standing space for the worker, preventing the worker from leaning out and causing the center of gravity to fall downward. At the same time, when the connecting rod frame 75 moves, the connecting rod frame 75 will drive the slide slot folding rod 78 to move, so that the end of the slide slot folding rod 78 slides along the inclined slot rod 79, so that the inclined slot rod 79 drives the connected side extension plate 710 to extend outward from the platform 51 after being stressed, so that the side extension plate 710 or the extension plate 74 at the extension can provide support for the worker's arm after the worker falls, so that in the subsequent rescue, the worker's arm can climb up with the side extension plate 710 or the extension plate 74 as support, and by increasing the standing space, the worker is prevented from leaning out, thereby improving the safety of the worker during installation work;

[0028] When the elastic beam rod 77 moves upward along the table 51, the elastic beam rod 77 pulls the connected locking link 81 to move, so that the locking link 81 slides upward with the locking frame 82. After the locking link 81 contacts the locking frame 82, it pushes the locking frame 82 to slide along the slide rail seat 84 again, and the locking block 83 connected to the side of the locking frame 82 is engaged with the limit groove strip 85 at the corresponding position on the bottom surface of the track beam 4, thereby fixing the table 51 and the track beam 4, preventing the slide rail seat 84 from moving to the specified position on the track beam 4 under the drive of the external motor. Walking above generates vibration, which causes the slide rail seat 84 and the track beam 4 to move under the action of vibration. The slide rail seat 84 is driven by an electric drive wheel and controlled by a remote control terminal as a prior art. The limiting groove bar 85 is engaged with the locking block 83 to prevent the slide rail seat 84 from being displaced by the vibration and causing the worker to fall during the installation operation, thereby improving the stability of the structural support of the table plate 51. At the same time, the buffer rubber block 87 connected to the side of the side seat rod 86 can cushion the worker's body after the worker falls, thereby preventing the worker from falling and being hit by the installation stand 3 and causing physical injury.
