Description

Technical Field

[0001] This utility model relates to the technical field of building construction, specifically to a safety fall prevention device for building construction. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities. It includes the planning, surveying, design, construction, and completion of various technical work and the completed engineering entity for the construction, renovation, or expansion of buildings and ancillary structures and facilities, as well as the installation of supporting lines, pipelines, and equipment. It also refers to the construction of various houses and buildings, also known as construction workload. In order to effectively adapt to the needs of building construction at different heights, suspended platforms are generally used as an auxiliary means to facilitate workers' safe operation at heights.

[0003] A search revealed a utility model patent in China with publication number CN215670954U: a safety fall arrest device for building construction, comprising a suspended platform, a step plate set in the bottom of the suspended platform, and a traction rope fall arrest mechanism set on the suspended platform; the suspended platform includes a protective frame, two side frames symmetrically arranged on both sides of the protective frame, and a cross frame between the two side frames; the traction rope fall arrest mechanism includes a locking frame set on the protective frame, a winding reel set on the locking frame, a traction rope with one end extending into the winding reel and wound inside the winding reel, a fixing seat set at the other end of the traction rope extending out of the winding reel, and a safety restraint belt passing through the fixing seat for binding the construction worker.

[0004] However, the height of the safety frame of existing building construction safety fall arrest devices is fixed and cannot be adjusted. When working at height, if the safety frame is too low, the safety is low and it is easy to fall. If the safety frame is too high, the safety is good, but it is inconvenient for workers to carry out construction work and affects work efficiency. It is impossible to adjust the appropriate protection height according to the worker's body. Therefore, a new type of building construction safety fall arrest device is needed to improve the above problems. Utility Model Content

[0009] Preferably, the buffer structure includes two second springs, which are symmetrically fixedly installed on the basket. The other end of each second spring is fixedly connected to a buffer box. A third spring is fitted on each second spring, and the two ends of each third spring are fixedly connected to the basket and the buffer box, respectively. Four fixing plates are symmetrically fixedly installed on the bottom of the basket. Two fixing plates on the same side are connected by a first connecting shaft. A rotating plate is rotatably installed on each of the two first connecting shafts. A second connecting shaft is fixedly installed on each of the two rotating plates.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figure 1 , Figure 2 and Figure 4 A safety fall arrest device for building construction includes a suspended basket 1, four suspension ropes 2 symmetrically fixedly installed on the suspended basket 1, and a buffer box 3 slidably installed on the suspended basket 1.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5The suspended platform 1 and the buffer box 3 are connected by a buffer structure. The buffer structure buffers the suspended platform 1, making it more stable. The buffer structure includes two second springs 18, which are symmetrically fixedly installed on the suspended platform 1. The other end of each of the two second springs 18 is fixedly connected to the buffer box 3. Each of the two second springs 18 is fitted with a third spring 19, and the two ends of each third spring 19 are fixedly connected to the suspended platform 1 and the buffer box 3, respectively. Four fixed plates 4 are symmetrically fixedly installed at the bottom of the suspended platform 1. Two fixed plates 4 on the same side are connected by a first connecting shaft 5. A rotating plate 6 is rotatably installed on each of the two first connecting shafts 5. A second connecting shaft 7 is fixedly installed on each of the two rotating plates 6. An auxiliary roller 8 is rotatably installed on each of the two second connecting shafts 7. Through the compression of the suspended platform 1 and the buffer box 3, the two second springs 18 and the two third springs 19 are compressed, causing the two rotating plates 6 to rotate and the two auxiliary rollers 8 to slide on the buffer box 3, thereby buffering and absorbing shocks to the suspended platform 1, making it more stable.

[0025] Please see Figure 1 , Figure 2 and Figure 4 The suspended platform 1 is equipped with four adjustment components, one of which includes an adjustment plate 9. The suspended platform 1 has an adjustment groove, and the adjustment plate 9 is slidably connected to the adjustment groove. A fixed box 10 is fixedly installed on the outer wall of the suspended platform 1. Two electric push rods 11 are symmetrically fixedly installed inside the fixed box 10. The other ends of the two electric push rods 11 are fixedly connected to the adjustment plate 9. After the construction personnel enter the suspended platform 1, they can drive the corresponding adjustment plate 9 to move by activating the corresponding two fixed boxes 10, thereby adjusting multiple adjustment plates 9 to a suitable height. This makes the construction work safer and more practical.

[0026] Please see Figure 1-4 Multiple first springs 13 are symmetrically fixed on the buffer box 3. Multiple first springs 13 on the same side are connected by buffer plates 12. Two buffer plates 12 are slidably connected to both ends of the buffer box 3. The multiple first springs 13 and buffer plates 12 work together to assist the buffer box 3 in buffering operations, reducing the impact damage to the buffer box 3.

[0027] Please see Figure 1 , Figure 2 and Figure 4 It should also be noted that four mounting blocks 14 are symmetrically fixed on the inner wall of the suspended platform 1. The four mounting blocks 14 are connected by four connecting rods 15. Each sliding safety rope 16 is slidably mounted on it. The other end of the sliding safety rope 16 is equipped with a hook to connect with the construction personnel. The setting of multiple sliding safety ropes 16 ensures the safety of the construction personnel in any direction.

[0028] Please see Figure 2 Multiple third springs 19 are fixedly installed on the suspended platform 1. The other end of each third spring 19 is fixedly connected to the buffer box 3. The arrangement of multiple third springs 19 makes the suspended platform 1 and the buffer box 3 more stable.

[0029] Please see Figure 4 Multiple pads 20 are fixedly installed at the bottom of the buffer box 3. The setting of multiple pads 20 increases the friction of the buffer box 3, making the buffer box 3 more stable when it lands.

[0030] In summary, when this safety fall arrest device for building construction is in use, the compression between the suspended platform 1 and the buffer box 3 causes the two second springs 18 and the two third springs 19 to compress, which in turn causes the two rotating plates 6 to rotate and the two auxiliary rollers 8 to slide on the buffer box 3. This buffers and reduces shock for the suspended platform 1, making it more stable. After the construction personnel enter the suspended platform 1, they activate the corresponding two fixed boxes 10. This electric actuator is a commercially available device known to those skilled in the art. Here, we are only using it practically and have not made any structural or functional improvements. Therefore, we will not elaborate further on it here. Furthermore, the electric push rod is equipped with a matching control switch. The installation position of the control switch can be selected according to actual practical needs, making it convenient for operators to operate and control, thereby driving the corresponding adjustment plate 9 to move and adjust multiple adjustment plates 9 to a suitable height, thus making the construction personnel safer during construction. One end of a suitable sliding safety rope 16 is connected to the construction personnel. The setting of multiple sliding safety ropes 16 ensures the safety of the construction personnel in any direction. The cooperation of multiple first springs 13 and buffer plates 12 provides auxiliary buffering for the buffer box 3, reducing the impact damage to the buffer box 3. It has high practicality.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
