Description

Technical Field

[0001] This invention relates to the field of engineering protection technology, and in particular to a safety protection device for engineering construction. Background Technology

[0002] Safety protection devices are needed to protect workers during construction projects. However, most existing safety protection devices lack fall protection features or simply have simple barriers, resulting in low safety and ineffective protection for workers. Furthermore, they are not convenient for emergency adjustments based on different usage conditions. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a safety protection device for engineering construction that can both prevent falls and avoid secondary injuries caused by falls.

[0004] The technical solution of the present invention is as follows:

[0005] A safety protection device for engineering construction includes a construction frame with a first baffle and a second baffle, a support frame fixed on the construction frame, a support plate connected to the support frame, and a fixing plate connected to the construction frame. A buffer warning component is provided on the support frame, and a transmission device capable of moving the support frame and the two baffles is provided on the construction frame.

[0006] With the above structure, when in use, the buffer warning component of the support plate can form a barrier to prevent the operator from falling and can buffer the impact of the fall. It can also sense the falling of heavy objects and issue a warning signal in time, thereby activating the transmission device. The transmission device drives the baffle to move and disconnects the connection between the support frame and the construction frame. At the same time, it drives the support frame to move and, together with the fixed plate, creates a semi-enclosed space for the person falling, which can prevent the person from suffering secondary impact injuries. The structure is simple and the operation is convenient.

[0007] To simplify the installation structure, preferably, the buffer warning assembly includes an air cushion, a mesh bag, and a tension sensor connected to a PLC controller, all mounted on a support frame. The output end of the tension sensor is provided with a pull wire connected to the mesh bag.

[0008] To avoid interference while ensuring sensitivity, preferably, the mesh bag is located at the upper end of the air cushion, and the pull line is fixedly connected to the upper surface of the mesh bag and runs through the mesh bag in the longitudinal direction.

[0009] To facilitate the movement of the support frame and reduce impact damage, the transmission device preferably includes a power motor connected to a PLC controller. The output end of the power motor is provided with a transmission rod that extends upward through the support plate. A threaded section is provided on the transmission rod at the corresponding position of the extension, and the threaded section is screwed to the support plate. A guide post is provided on the construction frame, and a guide sleeve is provided on the support frame at the position corresponding to the guide post. The guide sleeve is fitted on the outside of the guide post.

[0010] To avoid transmission interference and facilitate installation, preferably, the through end of the transmission rod protrudes upward from the upper end face of the fixing plate. The transmission device also includes an active tooth sleeved on the protruding end of the transmission rod. A first transmission tooth is provided on one side of the fixing plate to mesh with the active tooth, and a second transmission tooth and a third transmission tooth are provided on the other side to mesh with the active tooth. One side of the first transmission tooth meshes with a first tooth block fixed on the first baffle, and the third transmission tooth meshes with a second tooth block fixed on the second baffle.

[0011] To ensure the stability of the movement of the baffles, preferably, a guide groove is provided at the bottom of the construction frame at the position corresponding to the first baffle and the second baffle, and the bottom of the two baffles extends into the guide groove and can move along the axial direction of the guide groove.

[0012] To prevent people from falling out of the air cushion area, it is preferable to provide guardrails on the support frame.

[0013] Beneficial effects: The buffer warning component of this invention can prevent people from falling out in time and reduce the chance of injury. At the same time, the warning signal generated reminds people to activate the transmission device. On the one hand, it can drive the baffle to move and form a shield. On the other hand, once the construction scaffold falls, if people move to the position of the buffer warning component, it will drive the support to move upward to reduce the recoil injury caused by hard impact.

[0018] The invention will now be further described with reference to the accompanying drawings.

[0019] Depend on Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention includes a construction frame 1 with a first baffle 101 and a second baffle 102, a support frame 2 fixed on the construction frame 1, a support plate 21 connected to the support frame 2, and a fixing plate 22 connected to the construction frame 1. A buffer warning component is provided on the support frame 2, and a transmission device is provided on the construction frame 1 that can drive the support frame 2 and the two baffles to move.

[0020] Specifically, the buffer warning assembly includes an air cushion 3, a mesh bag 31, and a tension sensor 30 connected to a PLC controller 7, which is mounted on a support frame 2. The output end of the tension sensor 30 is provided with a pull line 32 connected to the mesh bag 31. The mesh bag 31 is located at the upper end of the air cushion 3, and the pull line 32 is fixedly connected to the upper surface of the mesh bag 31 and runs through the mesh bag 31 in the longitudinal direction.

[0021] The transmission device includes a power motor 4 connected to a PLC controller 7. The output end of the power motor 4 is provided with a transmission rod 40 that extends upward through the support plate 21. A threaded section 401 is provided on the transmission rod 40 at the corresponding position of the extension. The threaded section 401 is screwed to the support plate 21. A guide post 11 is provided on the construction frame 1. A guide sleeve 23 is provided on the support frame 2 at the position corresponding to the guide post 11. The guide sleeve 23 is sleeved on the outside of the guide post 11.

[0022] The through end of the transmission rod 40 protrudes upward from the upper end face of the fixing plate 22. The transmission device also includes an active tooth 5 sleeved on the protruding end of the transmission rod 40. On one side of the fixing plate 22, there is a first transmission tooth 51 that meshes with the active tooth 5, and on the other side, there is a second transmission tooth 52 that meshes with the active tooth 5 and a third transmission tooth 53 that meshes with the second transmission tooth 52. One side of the first transmission tooth 51 meshes with a first tooth block 61 fixed on the first baffle 101, and the third transmission tooth 53 meshes with a second tooth block 62 fixed on the second baffle 102.

[0023] A guide groove 12 is provided at the bottom of the construction frame 1 at the position corresponding to the first baffle 101 and the second baffle 102. The bottoms of the two baffles extend into the guide groove 12 and can move along the axial direction of the guide groove 12.

[0024] A guardrail 24 is provided on the support frame 2.

[0025] The method of using this invention is as follows:

[0026] like Figures 1 to 4As shown, during normal use, the construction frame 1 has an opening on one side corresponding to the support frame 2. The first baffle 101 and the second baffle 102 are located at the left and right ends of the opening, respectively, and the lower ends of the two baffles extend into the guide groove 12. At the upper ends of the two baffles, one side of the first transmission tooth 51 is engaged with the first tooth block 61 fixed on the first baffle 101. The third transmission tooth 53 is engaged with the second tooth block 62 fixed on the second baffle 102. In this way, when the construction worker falls or falls, the net bag 31 and the air cushion 3 can play a blocking and supporting role at the first time, and the construction worker can also grab the net bag 31 to avoid further slipping.

[0027] When a construction worker slips and falls onto the net bag 31, the air cushion 3 first acts as a buffer against the fall. At the same time, the worker's weight presses down on the net bag 31 and stretches the pull line 32 connected to the tension sensor 30. Then, the tension sensor 30 sends a signal to the PLC controller 6, which in turn sends a start command to the power motor 4. After the power motor 4 starts, it drives the transmission rod 40 to rotate, causing the screw-connected support frame 2 to move upward along the guide post 23 from the guide sleeve 11 and approach the fixing plate 22. Combined with the setting of the guardrail 24, a space with barriers on all sides is formed on the air cushion 3, ensuring that the construction worker will not fall out and suffer secondary injury.

[0028] When there is a risk of the construction frame 1 falling and the construction workers cannot get away from the vicinity of the construction frame 1 in time, the operators only need to quickly move to the air cushion 3, press down the pull line 32 on the net bag 31, so that the tension sensor 30 responds and sends a signal to the PLC controller and starts the power motor 4, so that the two baffles move closer to each other and the support frame 2 moves upward, reducing the chance of injury to the construction workers and effectively protecting their lives.

[0029] To prevent accidental activation of the power motor 4 and to provide timely warning and protection against personnel falling in, the sensing value of the tension sensor 30 should be appropriately selected. In this embodiment, the PLC controller 7 does not involve its program control; it only needs to be adapted to the tension sensor 30 and the power motor 4. Its specific connection method will not be described in detail. In addition, the power supply is placed on the construction frame 1, which is convenient for placement and electrical connection.
