Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides protection for the tail cord provided with a guide and a weight truck so that the tail cord can move smoothly in a diagonal elevator without being caught by equipment in the hoistway. It is a device.

The tail cord for an elevator is generally fixed in two places, the power supply end of the control device installed in the machine room and the power receiving end installed on the car side, and the middle part is movable so that it can follow the rise and fall of the car corner. It has a simple structure. For this reason, in an oblique elevator that descends at a constant angle of inclination, the lower end of the tailcoat (17) bent in a U-shape always moves in contact with the hoistway wall. There is a good chance that it could get caught on equipment in the hoistway, and protection of it is an essential condition when constructing a skew elevator.

An object of the present invention is to provide a guide for a tail cord in a diagonal elevator, and further,
By installing a weight trolley to ensure smooth movement of the tail cord, we aim to completely prevent the tail cord from getting caught in tower equipment when the elevator goes up and down. It is a protective device.

In conventional elevators that move up and down vertically, the tail cord hangs down vertically due to its own weight, so even when the elevator goes up or down, there is little chance of it getting caught on equipment in the tower. However, since an oblique elevator moves down a hoistway with a constant inclination angle, the tail cord will inevitably be pulled, resulting in damage to the equipment in the tower. I will multiply it. For this reason, a protective device is required to guide the entire movement of the tail cord.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 9. FIG. 1 shows the overall structure of a diagonal elevator. Prior to explaining the present invention, the structure of the skew elevator will be explained. The elevator car 1] is fixed to the support structure k, and moves while sliding on the support structure 1 (i.e., the rail 1, which is the vertical track of the elevator), the guide rollers U and the guide shoes J. - The counterweight B moves on the track rail while sliding the guide roller e and the guide shoe J. Also, the counterweight B moves on the track rail [''-] while sliding the guide roller e and the guide shoe J. Also, the counterweight B moves on the car structure with a hoisting machine (omitted). Sheave C
5 It is obvious that the winding machine sheave C is raised and lowered by the craftsman because it is directly connected with the rope through the deflection wheel 0. Since the hoistway wall '1' is inclined at a predetermined angle, the tail cord g fixed to the fixing support G of the control device a and the seat 1) is connected to the hoistway as shown in FIG. While in contact with wall T,
” You will have to use one. In addition, in the figure, S indicates the power receiving end relay box attached to the car, G indicates the fixing support bracket for the tail cord on the car side, g is the elevator shock absorber installed at the bottom of the hoistway, and r is the elevator shock absorber installed at the bottom of the hoistway. The entire road bottom wall is shown. Mai
, /- is an elevator -〇 A constant gravity is applied to the tail cord g so that it can move smoothly in parallel with unloading. There is a truck configured as n, and m is the tail cord. It has a structure that allows it to rotate without preventing the movement of the trolley t, and +1 is a wheel that evens out the movement of the trolley t.

1, bogie 17, n of all tail cords on the predetermined orbit p
It has a structure that moves up and down to follow the fall. Figure 2 shows the passenger car 1) and the tail cord support structure G on the passenger car side.
FIG. 2 is a cross-sectional view showing the guide D and weight truck in full detail, which allow smooth movement of the tail cord. 1 is the car guide rail, J is the guide shoe, [1 is the guide roller, W is the building side structure for fixing the guide rail, 1 is the car support structure, D is the tail cord that moves smoothly The figure shows a guide that is constructed so as to be able to do so. The L-shaped trolley is designed to apply a predetermined load so that the lowermost bent portion can move smoothly when the tail cord moves up and down. Incidentally, the travel trajectory of the wheel n that causes the bogie to travel the entire length is also formed from a part of the guide of the tail cord.

3 and 4 are detailed views of the tail cord weight truck. FIG. 3 is a front view of the truck, and FIG. 4 is a side view of the truck. n is wheel, t is
This is the structure of a weight truck, and the weight is set to allow smooth movement of the tail cord. g indicates the tail cord body. m is a part of the structure of the weight trolley, and since it comes into contact with the tail cord, it has a rotatable structure so as to follow the movement of the tail cord. Figure 5 shows all the moving states of the tail cord and the main p truck, the broken line shows the entire state before downward movement, and the solid line shows
The state after the movement is shown. In the figure, ■ is
This is the track of the weight truck, and the bottom of the guide along which the tail cord moves is fully shown. As shown in Fig. 5, if the entire tail cord moves on the slope with Il, IT order 1, there is no guide and the tail cord is fully loaded. This will result in the tail cord being cut. However, as in the present invention, if a predetermined load is always applied to the guide shoe, the tail cord can always move smoothly within the guide. As mentioned above, the contact area between the tail cord and the weight truck has a rotatable structure, so the tail cord will not be damaged. 6 to 9 show other embodiments of the tail cord guide. Figure 6.

Fig. 7 shows a method of constructing a guide as a guide in a building, and Figs. 8 and 9 show the entire method of installing a pre-made guide in a structure. Figure 6 shows a method in which the weight truck track and tail cord guide guide are fully integrated and installed on a building, and Figure 7 shows a method in which the weight truck track and tail cord guide guide are installed on a building and the tail cord guide guide is installed on the building. This is a way to donate money to a building. Fig. 8 shows a method in which only the track of the weight truck is laid in the building without constructing a guide for the tail cord. In this case, it is necessary to increase the diameter of the weight truck wheel n in order to secure a gap between the building F and the weight truck l to ensure sufficient movement of the tail cord. In the figure, L indicates the entire wheel guide rail. FIG. 9 shows a method of installing in a building a workpiece in which the tail cord guide I) and the track of the wheels n of the weight truck t are integrated. Particularly, in order to prevent the tail cord from coming into contact with the edge of the guide and being completely damaged, the tail cord has been designed to be bent.

According to the present invention, γL, as the stringer elevator moves up and down,
Since the tail cord can be moved without being drawn into equipment in the tower, it is highly effective as a tail cord protection device for diagonal elevators.
