Description

Guiding frames for bucket lifting are known, which are on a frame with four basmas.

The difference of the described guide frame consists in the development of the scientific research institute of each bashmak from two hingedly connected to the cheek cheeks by a vertical axis, the shank, the bracket and the spring-loaded roller located above the cheeks. In addition, openings are provided in the cheeks to enter them at the transition points of the pointed ends of rigid conductors, and opening and closing the cheeks when switching from flexible conductors to hard and vice versa is performed by moving the rollers and brackets, caused by the interaction of the rollers with rigid guides. Such an embodiment of the guide frame ensures on the horizon a zero platform transition from flexible cable conductors to rigid rail conductors and vice versa.

FIG. 1 shows a guide frame; in fig. 2-bashmak guide frame when moving in flexible conductors; in fig. 3-section AA-BB in FIG. 2; in fig. 4-bashmak guide frame when moving in rigid conductors; in fig. 5- bashmak in a section.

The guide frame consists of a frame with an umbrella, traverses and four bashmakov /. Each bashmak is made of two guide cheeks 2 with shanks 5 pivotally connected by a vertical axis 4, a bracket 5 located above the cheeks, and a roller 6 with a spring 7. The axis 4 enters the brackets 5 attached by means of bolts to the frame frame.

When the frame moves along flexible conductors, the cheeks of the bashmaks are closed and kept from opening by the brackets 5 and the springs 7. When the frame approaches the zero platform 8, the upper rollers slide onto the bevels 9 of the pointed ends of the hard guides and press out 126239

last inside the frame. In this case, the springs of the rollers are compressed, locking the ends of the brackets coming out of the straight section of the shanks, the pointed ends of the rigid conductors enter into the special holes 10 in the cheeks and the latter open. When the upper bashmaki come out on the section of hard conductors, the cheeks will fully open and will serve as bashmasks for hard conductors. When the frame is lowered, the rollers, moving along the bevels of the sharp conductors, under the action of the spring move in the direction of the ropes, press the brackets on the shanks and lock the cheeks, which in this case serve as guides for the flexible conductors.

In order to facilitate the closing of the cheeks when the shoes come off the rigid conductors, special skis 11 are provided. To protect the rollers from rotation when moving them in the horizontal plane, there are paired guides into which the brackets are fitted.

Subject invention

Claims (3)

1. A guide frame for bucket lifting consisting of a frame with four shoes, characterized in that, in order to provide on the horizon a zero transition site from flexible cable conductors to rigid rail conductors and vice versa, each bashmak is made of two pivotally connected vertical the axis of the guide cheeks with the shanks of the brace and associated with it and located above the cheeks of the spring-loaded roller. 2. The shape of the frame according to claim 1, differing from the fact that there are openings in the cheeks for entry into them at the junction points of the pointed ends of the rigid guides. 3. The form of the frame on PP. 1 and 2, characterized in that the opening and closing of the cheeks during the transition from flexible or rigid conductors, respectively, to rigid or flexible conductors, is carried out by moving the rollers and brackets caused by the interaction of the rollers with the rigid guides.
