DETAILED DESCRIPTION

[0025] The utility model object of the utility model is further described in detail below in conjunction with the drawings and specific embodiments. The embodiments cannot be described one by one here, but the implementation method of the utility model is not limited to the following embodiments.

[0026] Example 1 Figure 1 As shown, the integrated rope head assembly includes a self-locking head 203, two side plates 205 and three load-bearing plates 201. The load-bearing plates 201 are perpendicular to the side plates 205 and are formed by die casting. The upper ends of the three load-bearing plates 201 are provided with rod holes 204, and the three rod holes 204 correspond to each other. The three load-bearing plates 201 are arranged parallel to each other. The self-locking head 203 is inserted between two adjacent load-bearing plates 201, and the lower end of the self-locking head 203 protrudes between the lower ends of the two load-bearing plates 201. After the steel wire rope 4 is wrapped around the surface of the self-locking head 203, it is locked with the rope clamp 5. After the self-locking head and the side plates 205 further press the steel wire rope by the weight of the steel wire rope hanging object, a limit pin is placed in the pin hole 202.

[0027] The self-locking head 203 is used to fix the steel wire rope 4. The side plate 205 serves to enhance the connection strength between the load-bearing plate 201 and to lock the steel wire rope 4. The load-bearing plate 201 serves as a tensile support for the rope head rod 1 and the self-locking head 203. After the pin hole 203 is added with a positioning pin, it is used to prevent the self-locking head 203 from moving, and further prevent the steel wire rope 4 from loosening.

[0028] Each load-bearing plate 201 includes a rod head fixing part 2011 and two shaft end fixing parts 2012. The bottom of a rod head fixing part 2011 is connected to the tops of the two shaft end fixing parts 2012 respectively. The two shaft end fixing parts 2012 are connected to the rod head fixing part 2011 to form a "human" structure. The rod head fixing part 2011 is provided with a rod hole 204, and the shaft end fixing part 2012 is provided with a pin hole. Two adjacent shaft end fixing parts 2012 are connected by a side plate 205. The rod head fixing part 2011 is a square structure, and the top of the rod head fixing part 2011 is provided with two rounded corners. The connection between the rod head fixing part 2011 and the shaft end fixing part 2012 is provided with a chamfer. The shaft end fixing part 2012 is an inverted trapezoidal structure. Instructions for use of the rope head assembly 2:

[0029] like Figure 7As shown, the rope head rod 1 passes through the rod hole 204 of the load-bearing plate 201, and the two ends of the rope head rod 1 are fixed on two channel steels 3. The four self-locking heads 203 of the rope head assembly 2 are respectively connected to the four steel wire ropes 4, so that only one rope head assembly 2 is needed for multiple steel wire ropes 4, reducing the use of rope head cone sleeves and avoiding collision and abnormal noise between multiple rope head cone sleeves when using rope head cone sleeves. The use of the rope head assembly 2 can reduce the vertical installation space of the rope head assembly 2 and reduce the top floor space requirements. Furthermore, a shock-absorbing rubber block 6 can be added under the rope head rod 1 to further reduce the transmission of elevator operation noise to the machine room wall. Due to the force requirements of the current rope head cone sleeve, the rope head assembly 2 can only be placed vertically and cannot be placed horizontally, while the rope head assembly 2 of this embodiment can be placed horizontally and vertically.
