Abstract

The locking mechanism in such a design allows blocking the extension of the guided body in the rotating guide ring without limiting the rotation in the bearing of the guide body, or allows blocking the extension of the rotating guide ring in the bearing of the guiding body without limiting the displacement of the guided body in the rotating guide ring, or simultaneous blocking of displacement and rotation. This depends on the position of the locking member relative to the rotating guide ring. At the same time, it is only one simple mechanism that can be easily remotely controlled by a suitable control mechanism. The entire mechanism is space-saving. The invention will be used on a three-section telescopic boom of a universal finishing earthmoving machine with a typical size of 1 m3, which is being developed within the framework of a state task.

Description

BACKGROUND OF THE INVENTION The present invention relates to a locking device between a bearing guide and a guiding body against sliding or rotating movement.

Previously known locking devices made it possible to block only one relative movement of the two bodies. For example, only a lock against sliding movement, or a lock only against the rotational movement of the guided body relative to the guide. In cases where it was necessary to block two movements, two arresting devices had to be used, since with one arresting device it would not be possible to choose between blocking the two movements simultaneously or blocking only one of them. Thus, it was necessary to provide a yellowish interlocking system, difficult to control remotely, especially in cases where the space for storing the system was cramped.

The aforementioned drawbacks are eliminated by the device according to the invention, which consists of a locking pin for arresting the rotational movement of the guiding body relative to the bearing guide, the locking pin being connected to a locking spring intended to arrest the sliding movement of the guiding body relative to the bearing. a guide body, from a spring inserting the locking pin into the radial bore of the bearing and from the locking closure for extending the locking pin from the radial bore of the bearing against the spring pressure.

The bearing cap is connected to the actuating cylinder and the locking tongue is guided in the transverse groove of the rotating guide ring, the transverse groove being interrupted by a longitudinal slot for the guided body with the detent

The arresting device in such a configuration allows the guide body to slide out in the rotating guide ring without restricting rotation in the guide bearing bearing, or allows the guide body to rotate in the guide bearing bearing without restricting the movement of the guide body in the rotating guide ring, or lock and lock simultaneously. This depends on the position of the locking pin relative to the rotating guide ring and the locking tongue relative to the locking groove of the guided body. In this case, it is only one simple device which can be easily operated by means of a suitable actuating cylinder. The entire locking device is space-saving.

In the accompanying drawing, the construction of the detent device according to the invention is shown. 1 is a longitudinal cross-sectional view of the detent device, and FIG. 2 shows the detent device in section A - A, FIG. First

A bearing 3 with a radial bore 15 is received on the guide body 2, into which the bearing closure 5 is inserted manually or by means of a control cylinder 13 which is connected via a connecting pin 10 and a lever 8 pivotable around the pin 9 with the bearing closure 50. by inserting the bearing bolt 5 into the radial bore 15 of the bearing 3, at the same time the locking pin 6 is fully inserted into the rotating guide ring 4 and the locking tongue 16 connected to the locking pin 6 and guided in the sliding groove 14 formed in the rotating guide ring 4 is inserted into the locking groove 11 In this way, the extension of the guide body 1 in the rotary guide ring 4 is blocked and the rotation of the rotary guide ring 4 and thus of the guide body 1 in the bearing 3 of the guide body 2 is released. with the spring force 7, the locking pin 6 is pushed into the radial bore 15 at a suitable position of the guide ring 4 relative to the bearing 3. At the same time the locking tongue is pulled out of the locking groove 11. 1 in the pivot ring 4.

When the bearing cap 5 is automatically inserted into the radial bore 15, the guide body 1 is prevented from extending in the rotary guide ring and at the same time the rotation of the rotary guide ring 4 relative to the bearing 3 of the guide body 2 is blocked. 2), formed in the rotary guide ring 4, interrupted by the longitudinal slot 12, thereby creating a space for the locking groove 11 formed on the guided body 1.
