Description

I The invention relates to the mining industry, namely to devices for laying pipes in racks during the drilling and operation of the core. A device is known for laying pipes in racks when drilling a well including pushers mounted on the housing of a hydraulic cylinder interacting with a conveyor; the hydraulic drive station GONED is the residual of this design when it comes to water. A device for laying and feeding pipes is known, comprising a rack, a conveyor and its drive including a double-arm lever with a turn lock, a drive and kinematically associated sprocket C2}. The disadvantages of this device are design complexity and low reliability. The purpose of the invention is to simplify the design and increase the reliability of the device. This goal is achieved so that in the pipe laying device, containing a rack, a conveyor and its drive, including a double lever with a turn lock, a leading sprocket driven and kinematically connected with it, the conveyor drive is provided with a slider that is spring-loaded relative to the guide, wherein the double-shouldered lever with a rotation lock is fixed on the slider, and the guide at its ends has stops arranged to interact respectively with one of the arms of the double-arm and with the lock. FIG. 1 shows a general view of the device in FIG. 2 - the same plan view; in fig. 3 - installation of the drive mechanism; in fig. 4 drive mechanism at the end of the stroke; in fig. 5 - the same, at the moment of returning to the initial position; in fig. 6 - airborne A in FIG. 3, the drive mechanism is installed on the loading pipe; in fig. 7 - the same, the drive mechanism is set to the pipe unloading mode in FIG. 8, section B-B in FIG. 4. A device for laying pipes contains a rack 1 (FIG. 1), a rack 4. - 2 2, on which the movable carriage 3 with the bracket 4 is mounted. The bracket 4 has guiding chutes 5 (Fig. 1, 2), a bypass roller 6, a driving sprocket 7 (Fig. 2) and a fixed drive sprocket 8 of the drive 9, mounted on the arm 10 of the bracket A. In this case, the bypass roller 6, the drive sprocket 7 and the grooves 5 are interconnected by a chain conveyor 11 having blades 12. The drive 9 also contains a guide 13 (Fig. 3) and is mounted on the support plates 14 (FIG. 2) in the case of loading pipes into racks or onto support plates 15 in the case of unloading pipes. At opposite ends of the guide 13 (Fig. 3), an emphasis 16 is provided for turning off the spring-loaded retainer 17 and an emphasis 18 for turning the two-arm lever 19 of the actuator 9 (Fig. 1, 2) to the operating position. Two shoulders lever 19 (Fig. 3) is mounted on the pin 20 of the slide 21 with the possibility of rotation. The double-arm lever 19 has a spring-loaded retainer 17 and is provided with a spring 22 (Fig. 8) to deflect it from its working position. In turn, the slider 21 is mounted on the guide 13 and is equipped with a spring 23 (Fig. 3). On the slider 21, a longitudinal groove 24 (f. 8) is made, which responds to the spring-loaded retainer 17. The device operates as follows. The initial position is the carriage 3, moving along the rack 2 (Fig. 1), installed in the working position above rack 1. Before starting the laying of pipes in rack 1, the actuator 9 is fixed on the support pin 14 (Fig. 2). The slider 21 (Fig. 3), under the action of the spring 23, is mounted in the upper position on the guide 13, and the double-arm lever 19 is locked from rotation by the spring-loaded lock 17 and is in the horizontal position. Under the action of the supplied pipe, the double-shouldered lever 19 (Fig. 3 4) is lowered together with the slider 21 along

guide 13. The spring 23 is expanded in this case, the double-arm lever 19 with its free shoulder turns the drive sprocket. 8 and sprocket 1 coaxially connected to it (Fig. 2). In this case, the asterisk 7 interacts with the chain conveyor 11, which pushes the previously loaded pipes into the new position by means of the blades 12 (Fig. 1). The chain pitch is selected in accordance with the stroke of the slide 21 (FIG. 3), and the slide stroke is limited by the stop 16. The stop 16 at the end of the stroke of the slide 21 enters the groove 24 (FIG. 8) and pushes the spring-loaded latch 17 out of it.

As a consequence, the two shoulders arm 19 is turned by the action of the spring 22 and out of contact with the feed pipe and the drive sprocket 8 (Fig. 2). At the same time, the slider 21 (FIG. 3) under the influence of the spring 23 begins to rise along

with the guide 13. When approaching the upper position, the two-arm lever 19 (Fig. 5) rests against the shoulder 18 and returns to the working horizontal position. In this case, the spring 22 (Fig. 8) is loaded and operates as a damper. See shock impact from the inertia forces of the slide 21 and the return force of the spring 23 (Fig. 3).

In order to discharge pipes from the rack, the actuator 9 (Figs 1, 2, 7) is rotated 180 ° and secured to the base plate 15, and the process is repeated.

Due to the fact that the conveyor drive is carried out due to the weight of the supplied pipe, manual labor is eliminated when putting pipes in the rack in the course of their packing and unloading, the reliability of the device increases and its design is simplified.
