Description

Technical Field

[0001] This utility model relates to the field of fall protection technology in construction engineering, specifically to a fall protection device for construction engineering. Background Technology

[0002] Fall arrestor ropes are an important measure to protect workers' lives. In high-altitude operations, safety ropes effectively prevent workers from falling and reduce the risk of fall accidents. Generally, workers at height wear safety harnesses and carry two safety ropes, alternating between attaching the safety hooks of the two ropes to secure suspension points, following the principle of "high attachment, low use," to ensure their safety.

[0003] However, most of the existing fall protection safety ropes on the market only have the function of preventing falls. When workers accidentally fall, they are often suspended in the air by the safety rope. They lack a foothold in the air, making it difficult for them to save themselves. Moreover, the working environment at height is special and there are few people, making it difficult to quickly and safely rescue those hanging in the air. This greatly increases the risk of falling for those in need and threatens their lives. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a fall protection device for construction engineering. In the event of a user's fall, it prevents the user from falling violently and suspends the user. The user can also easily climb upwards along the safety rope through the one-way locking structure.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A fall arrest device for construction projects includes a safety rope, one end of which is connected and fixed with a safety hook, and the other end of which is connected and fixed together with a safety belt. It also includes:

[0007] A one-way locking structure is installed on the safety rope, allowing you to climb upwards along the safety rope using the one-way locking structure;

[0008] The foot pedal support structure, located on a one-way locking mechanism, provides a point of leverage for the user.

[0009] As an improvement, the one-way locking structure includes a sleeve, a handle, a locking tongue, and a spring; the sleeve is movably sleeved on the safety rope, the handle is a C-shaped structure, and both ends are respectively connected and fixed to the side wall of the sleeve, the locking tongue is vertically arranged between the sleeve and the handle, and the top is rotatably set on the handle, and the bottom side is connected to the handle by the spring, and the other side passes through the sleeve and abuts against the safety rope.

[0010] As an improvement, the contact surface between the locking tongue and the safety rope is evenly provided with multiple anti-slip spikes, and after the locking tongue comes into contact with the safety rope, the anti-slip spikes penetrate into the safety rope.

[0011] As an improvement, the foot pedal structure includes a hanging rope and a foot pedal ring; a hanging ring is formed at the bottom of the sleeve side wall, and one end of the hanging rope is connected and fixed to the hanging ring, while the other end is connected and fixed to the foot pedal ring.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1. This utility model is equipped with a one-way locking structure, which prevents the user from falling violently after a fall and keeps the user suspended, making it convenient to climb up the safety rope through the one-way locking structure to return to a safe high point. It has a self-rescue function and is more convenient, safe and labor-saving to use.

[0014] 2. This utility model is equipped with a foot pedal support structure, which can be stepped on with one foot to provide a point of leverage and maintain balance. Furthermore, by alternating the use of the foot pedal support structure, the climbing speed of the person falling can be accelerated, making it more convenient and safer to use.

[0023] A fall arrest device for construction projects, such as Figure 1 As shown, it includes:

[0024] Safety rope 1 is made of synthetic fiber. One end is connected and fixed with safety hook 2, and the other end is connected and fixed to safety belt (two sets of this invention are provided on the safety belt). A one-way locking structure is provided on safety rope 1, and a foot pedal force-bearing structure is provided on the one-way locking structure. A pair of one-way locking structures and a pair of foot pedal force-bearing structures are provided on the upper and lower edges of safety rope 1, respectively, and are arranged on the left and right sides of safety rope 1, as follows:

[0025] One-way locking structure such as Figure 2 , Figure 3 As shown, it includes a sleeve 3, a handle 7, a locking tongue 8, and a spring 9; the sleeve 3 is movably sleeved on the safety rope 1, the handle 7 is a C-shaped structure, and its upper and lower ends are respectively connected and fixed to the side wall of the sleeve 3, and the locking tongue 8 is shaped as follows. Figure 4 As shown, it is vertically arranged between the sleeve 3 and the handle 7, with the top rotatably mounted on the handle 7. One side of the bottom is connected to the handle 7 by a spring 9, and the other side has multiple anti-slip spikes 10 evenly formed. After passing through the sleeve 3 and contacting the safety rope 1, the anti-slip spikes 10 penetrate into the safety rope 1 (as shown). Figure 5 As shown), the handle 7 is provided with an anti-slip pad, and a hanging ring 6 is formed at the bottom of the side wall of the sleeve 3.

[0026] Foot pedal structure such as Figure 2 As shown, it includes a hanging rope 4 and a foot pedal ring 5; one end of the hanging rope 4 is connected and fixed to the hanging ring 6, and the other end is connected and fixed together with the foot pedal ring 5, and the foot pedal ring 5 is compatible with work safety shoes.

[0027] In the specific implementation of this embodiment:

[0028] After putting on the safety belt as required, carry the corresponding two sets of this new type of equipment for high-altitude operations. During the climbing process, use the two safety hooks 2 to alternately hook onto the high suspension point. After reaching the top, according to the principle of high hanging and low use, hook the safety hook 2 onto the high suspension point at the top, and always ensure that one safety hook 2 is in the hooked state during the movement.

[0029] When a user falls, they are suspended in the air by the new type of safety rope 1. They call for help from those around them, stabilize their body, lower the foot pedal ring 5 (corresponding to the safety rope 1) hooked on their waist, put both feet into the two foot pedal rings 5 ​​and step on them. Then, they lift one foot and slide the corresponding one-way locking structure upwards along the safety rope 1. They then use that foot to support themselves and stand up. They lift the other foot and slide the other one-way locking structure upwards along the safety rope 1 until they reach the bottom of the upper one-way locking structure. They alternate standing up like this until both one-way locking structures slide to the safety hook 2. With the help of others and by using surrounding objects, they move to a safe location.

[0030] After the operation is completed, pull the locking tongue 8 inward and slide the two one-way locking structures to the end of the safety belt.
