Abstract

DEVICE FOR COMPLETE INSTALLATION OF DISTRIBUTIONS, - including a ring on which support beams with latches are located, having a horizontal shaft and vertical jacks mounted on the shelf, so that, in order to improve Reliability of operation by To ensure the accuracy of the installation of the shootings, each vertical jack is provided with a platform with a ball bearing on it, which is connected with a ring by means of hooks.

Description

SL

The invention relates to the construction of a mine and mine construction, namely, the reinforcement of vertical shafts. A device for setting executions, consisting of surveying plumb lines and horizontal templates, is known. Each shooting in the armored reinforcement is established with respect to 1-2 plumb lines using templates, regardless of the other shootings of the rock Clj. The disadvantages of the known devices are the unequal accuracy of the installation of the shootings and, consequently, the poor quality of the reinforcement. Installing each shot individually requires a large number of surveyor plumbs (5-8) and a significant investment of time and cost. Most; A close technical solution to the proposed is a device for installation of executions, including a rigid ring with support beams and fixatives of executions on the upper floor of the ap shelf and provided with vertical and horizontal jacks for installing the ring in vertical and horizontal planes. The reinforcement shootings are laid on the support beams and the ring and fixed to the ring with retainers. The installation of the ring with executions in the vertical plane is performed by rigidly attached to the ring with vertical jacks on the template with respect to the previously established train of executions. In the horierntal plane, the ring is installed with horizontal jacks relative to the three surveying plumb lines on the rails on ring 2. The main disadvantages of this device are the difficulty of centering the ring in the horizontal plane. The purpose of the invention is to increase the reliability in operation by ensuring the accuracy of the installation of executions. The goal is achieved by the fact that in the device for a complete installation of executions, including a ring on which support beams with latches are located, having horizontal jacks and vertical jacks mounted on the shelf, each vertical jack is provided with a ball bearing pad on it, which by means of support bearings associated with the support ring. Figure 1 shows the proposed device, a General view; in Fig. 2 - Fig. A in Fig.; in Fig. 3 a section BB in Fig. 2; in Fig. 4 a section B-B in Fig. 2; The device consists of a ring 1 located on the reinforcement shelf 2 and support beams 3 rigidly attached to the ring 1 at the locations of the design of the shootings 4. The support beams 3 have clamps 5 that secure the shootings 4 to the ring 1 during jjpyca installation. To the ring 1 in the lower part four sockets 6 with support bearings 7 are diametrically opposed. Axle 9 with bearing 10 is rigidly seated on the inner sleeve 8 of each support bearing 7. Ball 11 is mounted on bearing 10, which with its outer surface rests on platform 12 rigidly mounted on the upper part of the vertical jack 13. The lower part of each vertical jack 13 is fixedly mounted on the reinforcement shelf 2. Three threads of 14 surveying plumb lines, relative to but which on the frame 15 is centered in the horizontal plane, the vertical ring 1 is centered relative to a previously installed tier 16 executions pattern centered 17. The locking ring 1 is effected mounted thereon horizontal jacks 18. The apparatus operates as follows ob- time. Ring 1 is centered on reinforcement shelf 2 in the vertical and horizontal planes. The centering of the ring 1 in the vertical plane is carried out as follows. Near the vertical jacks 13, between the luminous 16 installed above and the supporting beams 3 of the ring 1, the templates 17 are set to be equal to the design distance between the rus. With the help of vertical jacks 13 they raise (or lower the platforms 12, and with them the ring 1 by the required amount, up to the lower shelf of the template 17. Then, the centering of the ring 1 in the horizontal plane relative to the three surveyor plummets 14 is started. The ring 1 is moved on the platforms 12 in such a position that the reperts 15 arranged on it are opposite to the plumb lines 14. The free movement of the ring on the square 12 in any direction is ensured by the fact that the support balls 11 have two degrees of freedom each. bearing 10 relative to axis 9 and simultaneously with axis 9 rotates on sleeve 8 in support bearing 7 installed in slot 6. The ring 1 centered in this way is fixed with horizontal jacks 18. Next, executions 4 are placed on support beams 3 so that they go into latches 5, and connect them together in Rus.

After securing the ruse to the walls, the use of the invention will allow the barrel to free the latches 5 and reduce the reliability of the device, and horizontal jacks of the bot will rat.
