Description

the longitudinal movement along the traverse, and the fixation mechanism is made of a gear, mounted on the links of the traverse, a gear mounted on the casing of the hydraulic cylinder of the stepping reversing and engaging with the gear rack, two locking levers, which are installed with the possibility of engagement from one end with the specified wheel, pivotally fastened at the other end, respectively, with the rod and the cylinder of the cylinder of the fixation mechanism, and with their centers attached to the cylinder of the cylinder of the stepping movement.

In addition, the links of the drilling carriage are made of different lengths.

FIG. 1 shows a carriage, a general view (the extreme links of the transverse crosshead are shown rotated to a position along the undercarriage); in fig. 2 is a view along arrow A in FIG. 1 (traverse links are depicted in the working position); in fig. 3 is a diagram of the movement mechanism.

The drill carriage consists of a undercarriage 1, equipped with leveling jacks 2, a transverse traverse made of three links: a central link 3 rigidly connected to the undercarriage 1, and links 4 and 5 installed with the possibility of fixed rotation relative to the central link 3 to the position along the undercarriage 1. On the transverse cross bar, the platform 6 is mounted with the possibility of fixed movement for fastening the manipulators 7 with feeders of 8 drill masks onto them.

The drive of each platform is made from the hydraulic cylinder 9 of the shchagovoy movement mechanism, the body 10 of which is made rectangular and freely moving along the rectangular groove of the platform within a stroke limited by two output ends of the rod 11 mounted on the platform 6 and equipped with a gear wheel 12 and two levers stoppers 13, acting from the spring-loaded hydraulic cylinder 14 of the fixation mechanism.

Link 3, 4 and 5 transverse traverse from the side of the platform 6 are equipped with toothed rails 15, 16 and 17, which form a single rail when installing the extreme links 4, 5 transverse traverse in the working position.

Cross traverse has one transport position and three workers. The transport position corresponds to the installation of the extreme links 4, 5 in the position along the undercarriage 1. In this case, the envelope of the transverse traverse width corresponds to the size of the carriage. Each of the working positions of the transverse crosshead is determined by the number of its links and the length of the links are aligned in the same plane. Fixed turn

the links can be made in different ways; it is most advisable to turn by a hydraulic cylinder.

Each platform 6 has its own autonomous drive of movement and with its help it can move along the links of the transverse traverse installed in the working position, while freely moving relative to platform 6

the cylinder body 10 of the hydraulic cylinder 9 is fixed relative to the links 3, 4, 5 of the transverse beam through the gear wheel 12, which becomes stationary relative to the rack, for example, 17 after that

as the stop levers 13 rotated by the spring-loaded cylinder 14 will make it impossible to rotate. The rod And at this moment under the action of the hydraulic fluid is pushed out of the hydraulic cylinder 9, while simultaneously moving the platform 6 relative to the housing 10 of the hydraulic cylinder.

Due to the rectangular shape of the cylinder body 10 and the groove in the platform 6, the rotation of the hydraulic cylinder 9 relative to its longitudinal axis is eliminated, which is necessary for the normal operation of the engagement of the gear 12c with rails 15, 16, 17. The direction of movement of the platform is determined by which of the planes of the hydraulic cylinder 9 The pressure chamber of the spring-loaded hydraulic cylinder 14 is connected. The step of shifting is equal to the course of the hydraulic cylinder 9.

The use of a cross-beam, made of links, equipped with toothed racks, and an autonomous drive for each platform reduces the number of auxiliary operations, increases the utilization rate of each manipulator and increases the drilling productivity.

The use of cross-section links of different lengths allows for better reproduction of cross-section crossbars in workings of different widths.
