Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, and in particular to a device for preventing falling objects during construction. Background Technology

[0002] The existing announcement number is CN219175932U. A construction fall protection device includes: an adjustment device, a buffer device, and a support device. The adjustment device is rotatably connected to the buffer device. There are two buffer devices, which are symmetrically arranged. The lower end of the adjustment device is fixedly connected to the support device.

[0003] As mentioned above, when unfolding or folding the buffer and support devices for use or storage, corresponding operations need to be performed on the buffer and support devices respectively. If used in large quantities or for large-scale protection against falling objects, the operation is relatively time-consuming and laborious, and the use and recycling are relatively inconvenient. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fall protection device for building construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] By using a double-ended screw to drive two sets of threaded sleeves to adjust the spacing, the two sets of threaded sleeves can drive the first rod or the second rod respectively, so that the two sets of baffles can be unfolded and the two sets of plates can be moved out of the base for use, or the two sets of baffles can be closed and the two sets of plates can be moved into the base for placement and retrieval. When using large quantities of equipment for large-scale fall protection, the installation time can be shortened, which is relatively time-saving and labor-saving, and the use and retrieval are relatively convenient.

[0007] Preferably, both sets of plates are rotatably connected to multiple sets of rollers via connecting shafts.

[0008] Preferably, multiple sets of arched rubber blocks are installed at the two sets of baffles and the frame.

[0009] Preferably, the two sets of plates are slidably connected to the base.

[0010] Preferably, both sets of plates are fixed with through-hole blocks.

[0011] Preferably, a handle is fixedly connected to the double-ended screw.

[0012] Preferably, the outer wall of each of the multiple sets of rollers is fixedly fitted with a rubber sleeve.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By coordinating the double-ended screw, frame, through groove, double-ended screw, threaded sleeve, first rod, second rod, plate, and baffle, the double-ended screw drives two sets of threaded sleeves to adjust the spacing. This allows the two sets of threaded sleeves to drive the first or second rod respectively, unfolding the two sets of baffles and moving the two sets of plates out of the base for use, or closing the two sets of baffles and moving the two sets of plates into the base for storage and retrieval. This method can shorten installation time and save time and effort when using it in large quantities for large-scale fall protection, and it is relatively convenient to use and retrieve.

[0015] 2. Through the cooperation between the roller and the plate, when the two sets of plates are moved out of the base, the contact range between the plate and the base and the ground is increased, and the placement stability is increased. The roller can easily move the plate out. At the same time, the contact between the roller and the ground can also facilitate the movement of the device on the ground and make the position adjustment convenient. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5A construction fall arrestor includes a base 1, a frame 2 fixedly connected to the base 1, and two sets of through slots 3 formed in the base 1. The frame 2 is rotatably connected to a double-ended screw 4 via bearings. One end of the double-ended screw 4 and the other end are threadedly connected to threaded sleeves 5. The double-ended screw 4 can drive the two sets of threaded sleeves 5 to move in opposite directions. The two sets of threaded sleeves 5 are rotatably connected to multiple sets of first rods 6 or second rods 8 via connecting shafts. The two sets of threaded sleeves 5 can drive the corresponding first rods 6 or second rods 8 to move synchronously. The frame 2 is rotatably connected to two sets of baffles 7 via connecting shafts. When the baffles 7 are deployed, they can intercept falling objects. The two sets of baffles 7 are respectively connected to... Multiple sets of first rods 6 are rotatably connected. When the threaded sleeve 5 drives the first rods 6 to move up and down, the two sets of baffles 7 can be unfolded or closed. Multiple sets of second rods 8 pass through the corresponding through slots 3. Multiple sets of second rods 8 are rotatably connected to two sets of plates 9 through connecting shafts. Both sets of plates 9 are located at the base 1. When the threaded sleeve 5 drives the second rods 8 to move up and down, the two sets of plates 9 can be pulled out or retracted into the base 1. With the help of the rotation of the double-headed screw 4, the two sets of baffles 7 can be unfolded and the two sets of plates 9 can be pulled out of the base 1 for use. The two sets of baffles 7 can also be brought together and the two sets of plates 9 can be retracted into the base 1 for shielding and recycling. The use and recycling are relatively convenient.

[0024] In this embodiment, multiple sets of rollers 10 are rotatably connected to the two sets of plates 9 via connecting shafts. The rollers 10 facilitate the movement of the device and also allow the plates 9 to be easily pulled out or retracted into the base 1. Multiple sets of arched rubber blocks 13 are installed at the two sets of baffles 7 and the frame 2. The arched rubber blocks 13 can buffer falling objects from the building. The two sets of plates 9 are slidably connected to the base 1, and the plates 9 can slide laterally at the base 1, which can improve the stability of the second rod 8 pulling the plates 9 laterally. Through-hole blocks 11 are fixed to both sets of plates 9. The through-hole blocks 11 are used to pass through external connectors. After the external connectors are inserted into the ground, the device can be fixed on the ground. A handle 12 is fixed to the double-headed screw 4. The handle 12 is used to drive the double-headed screw 4 to rotate. Rubber sleeves are fixed to the outer walls of the multiple sets of rollers 10. The rubber sleeves are used to increase the contact friction between the rollers 10 and the ground, and improve the stability of the roller 10 pulling device on the ground.

[0025] The working principle of this embodiment is as follows: During use, the device can be moved by the contact between the roller 10 and the ground. When it is moved to the designated area, the handle 12 drives the double-headed screw 4 to rotate. The double-headed screw 4 can move the two sets of threaded sleeves 5 towards the end closer to the base 1 or the baffle 7. At this time, the two sets of threaded sleeves 5 can pull the first rod 6 or the second rod 8 to rotate and unfold the two sets of baffles 7. The two sets of plates 9 protrude from the base 1, and the device is unfolded and put into use. After unfolding, the external connector is inserted through the through hole block 11 and the external connector is inserted into the ground. The whole can be fixed. When the building falls on the two sets of baffles 7 and the frame 2, it will come into contact with the arched rubber blocks 13 at the frame 2 and the two sets of baffles 7. With the cushioning of the building falling by the arched rubber blocks 13 and the interception of the building falling by the baffles 7, the falling object protection operation can be achieved.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
