Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of construction engineering equipment, and particularly relates to a rope passing device. BACKGROUND

[0002] Generally, in order to prevent high-falling accidents, a horizontal safety protection rope is set for a worker when the worker is working at an edge. The worker can work at the edge after a safety belt hook is hung on the horizontal safety protection rope. The hook can be shifted left and right on the horizontal safety protection rope with the movement of the worker, which ensures the convenience of the worker and the safety of the worker. However, when the horizontal safety protection rope has a large span, the safety protection rope will swing due to a large natural sag, and therefore the safety protection rope needs to be connected and fixed to a structure column, which causes the safety belt hook to be unable to continuously shift on the horizontal safety protection rope at the column. When the worker crosses the structure column from left to right, the hook needs to be taken off from the horizontal safety protection rope on the left side of the column, and then the hook is hung on the horizontal safety protection rope on the right side of the column. During this period, the worker has a high risk of falling, and a safety accident is likely to occur, which causes unpredictable accidents. The present application is to eliminate the safety risk of the safety belt hook during the edge work, and provides a new rope passing device which can fix the safety rope and does not hinder the shifting of the safety belt hook.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0026] Embodiment 1. Please refer to Figures 1-13The present invention provides the following technical solution: a rope passer, comprising a safety rope 1, a rope buckle 2, a guide groove 3, and a main housing 8. The guide grooves 3 are installed on both sides of the main housing 8, and there are two guide grooves 3. Two crescent bearings 4 are installed on both sides inside the main housing 8. Each crescent bearing 4 has a continuous straight sliding groove 402 on its side wall. A steel ball slide 401 is provided on the inner side wall of the crescent bearing 4, and rotating steel balls 5 are installed in the steel ball slide 401. The number of moving steel balls 5 is several. A self-locking wheel 6 is installed inside the main housing 8. The rope buckle 2 is slidably arranged inside the self-locking wheel 6. The rope buckle 2 is composed of a hook connecting rod 201 and a shuttle rod 202. The shuttle rod 202 cooperates with the self-locking wheel 6. Under the action of thrust, the shuttle rod 202 can move inside the self-locking wheel 6. The safety rope 1 can be inserted into the self-locking wheel 6 and the shuttle rod 202. Under the action of thrust, the self-locking wheel 6 and the shuttle rod 202 can move relative to the safety rope 1.

[0027] The self-locking wheel 6 is a hollow cylinder. A wedge-shaped hole 602 is formed on the side wall of the self-locking wheel 6. The cross-section of the inner hole of the wedge-shaped hole 602 on the self-locking wheel 6 is smaller than that of the outer hole. A continuous curved slide 601 is formed on the side wall of the self-locking wheel 6. A limiting steel ball 7 is installed inside the wedge-shaped hole 602. The main housing 8 is a hollow cylinder. A through hole 801 is formed on the side wall of the main housing 8. A continuous straight slide 802 is formed on the side wall of the main housing 8. A pin 9 is provided in the wedge-shaped hole 602 and the through hole 801. A spring 10 is also installed inside the through hole 801. A cover plate 11 is installed on the outside of the through hole 801. One end of the guide groove 3 is flared. A figure-eight continuous slide 301 is formed on the side wall of the guide groove 3.

[0028] The working principle and usage process of this invention: When the span of the horizontal safety rope 1 at the edge is too large, the safety rope 1 is threaded into the new rope guide, and the main housing 8 is fixed to the structural column according to the required height, thereby preventing the safety rope 1 from sagging and ensuring that the safety rope 1 is taut and will not sway. When working at the edge, the construction worker connects the safety belt hook to the hook connecting rod 201, so that the construction can be moved by the rope buckle 2 and the safety rope 1. Under normal conditions, the spring 10 in the through hole 801 is in a stretched state. The spring 10 pushes the pin 9 into the wedge hole 602 of the self-locking wheel 6, and the self-locking wheel 6 and the main housing 8 are locked. At this time, the limiting steel ball 7 partially protrudes out of the wedge hole 602, as shown in the attached figure. Figure 4 As shown. When construction workers need to move to the other end of the structural column, they must hold a rope hook 2 and pass it through the guide groove 3 at one end to enter the self-locking wheel in various situations. Figure 6As the rope buckle 2 is inserted, the shuttle rod 202 touches the limiting steel ball 7, and the limiting steel ball 7 is pressed into the wedge-shaped hole 602, the pin 9 is lifted to be separated from the wedge-shaped hole 602 of the self-locking wheel 6, and the spring 10 is in a contracted state, as shown in FIG. 6c. Figure 5 After the pin 9 is lifted, the self-locking wheel 6 is separated from the main shell 8, and the self-locking wheel 6 can rotate relative to the main shell 8 through the half moon bearing 4. The rope buckle 2 is continuously pushed, the self-locking wheel 6 rotates through the long curved slide 601, and the rope buckle 2 passes through smoothly, as shown in FIG. 6d. Figure 7 After the shuttle rod 202 is separated from the other end guide groove 3, the self-locking wheel 6 is reset, the spring 10 lifts the pin 9, and the self-locking wheel 6 and the main shell 8 restore the locked state, as shown in FIG. 6e. Figure 4 Through the above steps, the construction worker wearing the safety belt can quickly and safely cross the structural column to perform the edge work, without the “hook changing” operation, and the safety and convenience of the construction are ensured.

[0029] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not used to limit the present application, although the present application is described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
