Description

Technical Field

[0001] The utility model relates to the technical field of building construction safety, in particular to a rear-mounted safety rope and safety belt fixing point structure. Background Art

[0002] The safety rope is the lifeline for hanging basket operation and building facade installation and cleaning operation. Under the existing technical conditions, almost no special fixing point for the safety rope is set on the roof of any building.

[0003] In this case, the safety rope has to be temporarily fixed to the structural part of the building where the firmness is not uniform, which causes great safety hazards to production. In addition, the safety belt is required to be hung high and used low. In the same situation, there is usually no structural part of the building where the safety belt needs to be hung safely.

[0004] In order to ensure production safety and improve the safety facilities system, an innovative fixed point structure for both rear-mounted safety rope and safety belt has been designed. Utility Model Content

[0005] In view of the above problems existing in the prior art, the utility model aims to provide a rear-mounted safety rope and safety belt fixing point structure. The use of this fixing point structure solves the problem of the safety rope having no reliable hanging point, is simple to manufacture, and is convenient and reliable to install and use.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A rear-mounted safety rope and safety belt fixing point structure comprises a base plate, a support plate is vertically arranged on one side of the base plate, and the other side of the base plate is opposite to the building main body; a U-shaped ring is arranged above the support plate, the U-shaped ring and the support plate are parallel to each other, and the open end of the U-shaped ring is vertically arranged on the base plate; a swing mechanism is arranged on the support plate at a position away from one side of the base plate, and the swing mechanism and the U-shaped ring are limitedly matched, so that after the safety rope is hung, automatic blocking is achieved under the action of gravity.

[0008] Furthermore, a square notch is provided at one end of the support plate for installing the swing mechanism, and the shape of the notch may also be other forms.

[0009] Furthermore, the swing mechanism includes a shaft ring and a swing needle. The shaft ring is arranged on the support plate and is located at opposite positions on both sides of the slot. The swing needle is movably arranged on the shaft ring.

[0010] Furthermore, the pendulum needle is cross-shaped, and the pendulum needle includes a pendulum shaft, a pendulum needle head arranged above the pendulum shaft and a pendulum needle tail arranged below the pendulum shaft. The pendulum needle head and the pendulum needle tail are coaxially welded on the pendulum shaft. After the rope loop of the safety rope is fed into the pendulum needle head, under the action of the gravity of the pendulum needle tail (the length or mass of the pendulum needle tail is greater than that of the pendulum needle head), the pendulum needle head cooperates with the U-shaped ring to complete the blocking of the rope loop of the safety rope.

[0011] Furthermore, the length of the pendulum needle head should be greater than the distance between the U-shaped ring and the supporting plate to ensure that the pendulum needle head can cooperate with the U-shaped ring in a limited manner.

[0012] Furthermore, a stiffening plate is provided on the bottom surface of the support plate and perpendicular to the support plate and the base plate, and the stiffening plate plays a supporting role.

[0013] Furthermore, two long oval bolt holes are symmetrically opened on one side of the base plate, and expansion bolts are passed through the long oval bolt holes to achieve fixation between the base plate and the building body.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1) Simple installation: The utility model can be used after being fixed and installed with expansion bolts.

[0016] 2) Wide scope of application: The utility model can be installed on the vertical building structure and can also be installed on the flat cast-in-place structure. Therefore, it can be used for hanging safety ropes and safety belts.

[0017] 3) Easy to use: After the loop of the safety rope is servo-fed into the pendulum needle head, the pendulum needle head automatically blocks the loop of the safety rope under the action of gravity.

[0018] 4) Safety management benefits: By fixing the utility model on the building structure for a long time, when encountering security threats, it can provide the most convenient safety rope or safety belt fixing safety facilities and the fastest locking method for production and distress personnel, creating time opportunities for risk avoidance.

[0019] 5) Low cost: The utility model has low production cost and can be used as a tool for long-term turnover.

[0020] 6) The utility model fills the technical gap of building structures without safety rope hanging points, and also provides reliable hanging points for safety ropes and safety belts for later building facade cleaning, air conditioning installation, fire rescue, etc., to ensure operation safety.

[0030] like Figure 3 As shown, the base plate 1 is a rectangular steel plate with a thickness of 10 mm, and two oblong bolt holes are symmetrically opened on the upper and lower sides. The support plate 2 and the U-shaped ring 7 are welded on the base plate 1. Figure 5 shown.

[0031] The support plate 2 is a rectangular steel plate with a thickness of 10 mm. A square notch is provided at one end of the short side of the support plate 2. A shaft ring 5 and a pendulum pin 7 are installed at the notch. One end of the notch is vertically welded to the base plate 1. Figure 4 shown.

[0032] The stiffening plate 3 is in the shape of a right triangle and is made of a 10 mm thick steel plate. A triangular stiffening plate 3 is welded on the bottom surface of the support plate 2 and perpendicular to the support plate 2 and the base plate 1 .

[0033] The shaft ring 5 is a φ25 round tube. Two shaft rings 5 ​​are welded in opposite directions on both sides of the square notch of the support plate 2 . The concentric axis formed by the two shaft rings 5 ​​is perpendicular to the long side of the support plate 2 .

[0034] The pendulum needle 7 is cross-shaped and made of φ20 round steel. The left and right sides of the pendulum needle 7 are pendulum shafts 6. The upper part of the pendulum shaft 6 is the pendulum needle head, and the lower part is the pendulum needle tail. The head and tail are coaxially welded on the pendulum shaft 6, and the length and mass of the pendulum needle tail are greater than the pendulum needle head.

[0035] The U-shaped ring 4 is made of φ20 round steel bent into a U-shape, with an opening net width of 30 mm, and the opening end is vertically welded to the base plate 1; the symmetry axis of the U-shaped ring 4 is in the same plane as the head axis of the pendulum needle 7.

[0036] A rear-mounted safety rope and safety belt fixing point structure, wherein four expansion bolts are passed through the oblong bolt holes on the base plate 1 to fix the fixing point structure to the vertical surface or plane of the building structure;

[0037] When in use, if a safety rope is used, after the safety rope loop is servo-fed into the pendulum needle head, the pendulum needle head will instantly complete the locking of the safety rope loop under the gravity of the pendulum needle tail.

[0038] If a safety belt is used, after the fixing point structure is installed and fixed, the buckle of the safety belt can be directly buckled on the U-shaped ring 4.

[0039] The production and installation process of this fixed point structure is as follows:

[0040] 1) Make substrate 1: First, make four symmetrical cuts on a rectangular steel plate 30 mm away from the short side.

[0041] Long oval bolt hole.

[0042] 2) Making the support plate 2: Cut a 30mm*30mm notch on the short side of one end of the support plate 2, where the collar 5 and the swing pin 7 are installed. The other short side of the support plate 2 is vertically welded to the base plate 1.

[0043] The right-angled triangle-shaped stiffening plate 3 is welded perpendicularly to the support plate 2 and the base plate 1 at the same time.
