Description

Technical Field

[0001] The utility model relates to the technical field related to protective devices, in particular to a high-altitude operation protective device for construction engineering. Background Art

[0002] The so-called high-altitude work usually refers to high-altitude work, which refers to the work performed by people at a height based on a certain position. The high-altitude work in construction mainly includes five basic types: edges, openings, climbing, hanging, and crossing. These types of high-altitude work are the main places where high-altitude work casualties may occur.

[0003] As in the prior art, the Chinese patent authorization number is CN211421908U, the application date is 2020-09-04, and the name is a high-altitude work protection device for construction, including a protective frame, a limit rod and a support frame, the bottom side of the limit rod is provided with a spring, and the bottom side of the spring is connected to a fixed rod, the support frame is installed at the bottom end of the fixed rod, and a storage rack is installed on the left side of the support frame, the upper side of the storage rack is connected to a rainproof cloth, a take-up wheel is installed on the right side of the support frame, and a card foot is provided at the bottom end of the support frame, and a hanger is provided on the inner side below the support frame. The device is provided with a protective frame, which is arranged directly above the device. The protective frame has good anti-impact performance and is connected to the fixed rod by a spring. When an object hits the protective frame, the protective frame achieves the purpose of shock absorption by squeezing the spring downward, thereby reducing the impact of the impact. A tarpaulin is provided. During construction, when it suddenly rains, the tarpaulin can be used to cover the device to prevent rain from damaging construction materials on the hanger.

[0004] However, the above patent still has the disadvantage that after buffering the falling objects from high altitude, the falling objects from high altitude cannot be collected, so the falling objects from high altitude are likely to fall to the ground, which may easily cause safety hazards to people on the ground and further reduce the safety performance of the protective device.

[0005] For this reason, we propose a high-altitude working protective device for construction engineering. Utility Model Content

[0006] The purpose of the present utility model is to provide a high-altitude work protection device for construction engineering to solve the problems raised by the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a high-altitude work protection device for construction projects, including a hanger, the top of the hanger is fixedly connected to a support rod, the top of the support rod is fixedly connected to a protective top plate, the top of the protective top plate is fixedly connected to a buffer mechanism, the top of the buffer mechanism is fixedly connected to a protective frame, and protective mechanisms are arranged around the protective frame; the protective mechanism includes a connecting rod fixed to the bottom of the buffer mechanism, the end of the connecting rod is provided with an extension rod, both sides of the extension rod are fixedly connected with hooks, and the surface of the hook is hooked with an anti-fall net.

[0008] Furthermore, the buffer mechanism includes a fixed rod fixed to the top of the protective top plate, a sliding block is slidably connected to the surface of the fixed rod, and the sliding block is fixed to the inner wall of the protective frame.

[0009] Furthermore, the connecting rod and the extension rod are rotatably connected via a locking bolt, and the size of the extension rod is smaller than that of the connecting rod.

[0010] Furthermore, a buffer spring is sleeved on the surface of the fixing rod, and one end of the buffer spring is fixedly connected to the protective top plate.

[0011] Furthermore, four groups of lifting ears are fixedly connected to the top of the protective top plate, and the four groups of lifting ears are distributed at the four corners of the protective top plate.

[0012] Furthermore, the protective frame is conical in shape, and the four sides of the protective frame are distributed on the anti-fall net.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0014] The utility model can collect falling objects from high altitudes through the cooperation between the connecting rod, the extension rod, the hook and the anti-falling net. Through this arrangement, the collection and storage of falling objects from high altitudes is realized, thereby preventing falling objects from high altitudes from causing safety hazards to people on the ground, and further improving the safety performance of the protective device.

[0015] The utility model can buffer when falling objects from high altitude hit the buffer mechanism through the cooperation between the protective frame and the buffer mechanism. Through this arrangement, the impact force can be reduced, and the deformation of the protective device caused by excessive force can be prevented, thereby further extending the service life of the protective device.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-3 The utility model provides a technical solution: a high-altitude work protection device for construction engineering, including a hanger 1, a support rod 2 is fixedly connected to the top of the support rod 2, a protective top plate 3 is fixedly connected to the top of the protective top plate 3, a buffer mechanism 4 is fixedly connected to the top of the buffer mechanism 4, a protective frame 5 is fixedly connected, and a protective mechanism 6 is arranged around the protective frame 5; the protective mechanism 6 includes a connecting rod 61 fixed to the bottom of the buffer mechanism 4, an extension rod 62 is provided at the end of the connecting rod 61, and hooks 63 are fixedly connected on both sides of the extension rod 62, and an anti-fall net 64 is hooked on the surface of the hook 63. The support rod 2 on the hanger 1 can support the protective top plate 3, thereby ensuring the stability of the protective top plate 3. The stability performance of the buffer mechanism 4 can be guaranteed through the protective top plate 3, thereby improving the supporting effect of the buffer mechanism 4 when it is working, and the protective frame 5 can also be used to prevent rain and play a sunshade role.

[0023] according to Figure 2 It can be seen that the buffer mechanism 4 includes a fixed rod 41 fixed to the top of the protective top plate 3, and the surface of the fixed rod 41 is slidably connected to a sliding block 42. The sliding block 42 is fixed to the inner wall of the protective frame 5. The sliding block 42 slides on the surface of the fixed rod 41, so that it moves downward when encountering falling objects from high altitude on the surface of the protective frame 5, thereby reducing the impact force of falling objects from high altitude.

[0024] according toFigure 3 It can be seen that the connecting rod 61 and the extension rod 62 are rotationally connected through a locking bolt. The size of the extension rod 62 is smaller than that of the connecting rod 61. The connecting rod 61 and the extension rod 62 are rotationally connected through the locking bolt, so that the angle between the connecting rod 61 and the extension rod 62 can be changed arbitrarily, so that falling objects can be better collected and protected.

[0025] according to Figure 2 It can be seen that a buffer spring 43 is sleeved on the surface of the fixed rod 41, and one end of the buffer spring 43 is fixedly connected to the protective top plate 3. Through the spring force of the buffer spring 43, it can apply a reaction force to the bottom of the sliding block 42, thereby quickly resetting the sliding block 42, thereby buffering the weight of falling objects from high altitude for protection.

[0026] according to Figure 1 It can be seen that four groups of lifting ears 7 are fixedly connected to the top of the protective top plate 3. The four groups of lifting ears 7 are distributed at the four corners of the protective top plate 3. The setting of the lifting ears 7 makes it easy to pass through and connect the steel cables, so as to perform high-altitude lifting work on the whole.

[0027] according to Figure 1 It can be seen that the shape of the protective frame 5 is conical, and the four sides of the protective frame 5 are distributed on the anti-fall net 64. When the protective frame 5 is conical, it can disperse falling objects from high altitude to the surroundings so that they can be better caught when they fall on the anti-fall net 64.

[0028] The working principle of the present utility model is as follows: during operation, the hanger 1 is lifted by an external lifting device and raised to the construction site. When an object falls from above, it hits the protective frame 5, and the protective frame 5 drives the buffer mechanism 4 downward to work. The protective frame 5 converts part of the impact energy into elastic potential energy, thereby reducing the impact on the protective frame 5 and increasing the service life of the protective frame 5. At the same time, the protective frame 5 can slow down the force of falling objects from high altitude and move them around. Then, the protective mechanism 6 can collect falling objects from high altitude to avoid the continuous falling of falling objects from high altitude and causing safety hazards to people on the ground. When the protective mechanism 6 is working, it is fixed to the side wall of the protective frame 5 by the connecting rod 61, and then connected to the end of the connecting rod 61 by the extension rod 62. The anti-falling net 64 can be installed through the hook 63, so that it can collect falling objects from high altitude around the protective frame 5 through the anti-falling net 64.
