Description

The utility model relates to the field of construction of subways and tunnels and is intended for turning and moving to a mine shaft for issuing to the surface of large-sized nodes of a mining mechanized complex, metal structures, etc.

Known devices for turning the rolling stock of railways, in underground workings, cars, etc.

For example, a reversal device is known that includes a support frame, a circular support rail, a turntable with sliders for installation on a circular support rail. See Mine Transport, ed. I.G.Shtokmana, Nedra Publishing House, Moscow, 1964, p. 163 (chap. XII, 2.1 - Turntables)

The known device is designed to turn the rolling stock of railways with the aim of their further movement in any other direction.

Known devices for turning large equipment in underground workings of limited size.

For example, there is a device for reversing a tunnel shield (large equipment), which is used exclusively for turning large-sized equipment (in this case, a tunnel shield) (Eurasian patent No. 012896, application No. 200801087, publication date 12/30/2009) - prototype.

The essence of the known device is that large-sized equipment is installed on a movable platform, the platform-equipment system is moved to the reversal chamber, where the system is rotated to a full turn, then the system is moved to the transport tunnel.

The device for turning contains a supporting movable platform with supporting elements (wheels) connected to it by means of a connecting element.

The known device according to patent EA No. 012896 is intended mainly for turning a heading shield, which, being a large-sized equipment, at the same time has the correct geometric dimensions.

Turning the heading shield does not require any additional efforts and special technical equipment for turning. Turning the tunnel shield is carried out by means of a turntable of a special design (see the description of patent EA No. 012896) mounted on a circular rail in a reversal chamber. In fact, they make a usual turn of the product around its axis.

However, the construction of underground tunnels (in particular, subway tunnels) may involve large-sized equipment of various configurations and different geometric sizes (for example, having a large length or width, or a large length and width at the same time, etc.)

The use of a turntable for a turn in underground workings of such equipment is impossible, since the dimensions of the equipment do not allow its simple turn around its axis. Forms of equipment during a turn can simply rest against the wall of the mine.

At present, when the question of the construction of new metro stations is most acute, special attention should be paid to the modernization of equipment and the simplification of its operating conditions.

The technical task of the proposed utility model is the development of a device that provides for turning and moving large-sized equipment in underground workings of limited size during the construction of new metro lines. (For example, from a dismantling chamber to a transport tunnel to a shaft shaft for delivery to the surface or in the opposite direction.)

The technical result is achieved by the fact that in the device containing a movable platform with support wheels connected to it via a vertical axis, a support beam is also included, made with vertical holes located along its length at a distance from each other, a spacer element made with the possibility of regulation lengths and connected to each other through a stationary deflecting unit, a winch with a traction rope, a movable platform mounted on balancer trolleys, the vertical axis of each support the second wheel of the moving platform is located inside a vertical hole made in the balancing carriage, the supporting wheels are connected to the vertical axis by horizontal axes, the longitudinal axis of symmetry of which is offset from the longitudinal axis of symmetry of the vertical hole of the balancing carriage, brackets with vertical brackets are fixed at the ends of the platform in front and rear holes for swiveling with one of the ends of the traction rope and the spacer element, respectively, and the support beam is rigid o is fixed on the wall of the reversal chamber opposite the transport tunnel, and a fixed deflecting unit is fixed on the wall of the transport tunnel.

The proposed device is illustrated by drawings, which are presented on:

Figure 4. Support beam and spacer element (node B);

Figure 5. Scheme of the turn of the platform with the shield body (plan) - example 1;

6. Scheme of the turn of the platform with a screw conveyor (plan) - example 2.

Figure 1 shows a General view of the reversal device (plan) and the plan of the underground mine. The plot of the underground workings includes a reversal chamber 1 with adjacent transport tunnels 2, 3 and 4. The U-turn of the platform-equipment system is carried out directly in the reversal chamber 1.

The proposed device for the rotation includes a movable platform 5, a support beam 6, a spacer element 7, a winch (not shown), connected to the traction rope 8 through a stationary deflecting unit 9 (Fig. 1).

The movable platform 5 (Fig. 3) is mounted on the balancing trolleys 10. The vertical axis 11 of each support wheel 12 of the platform 5 is placed inside the vertical hole 13 of the balancing trolley 10. Each supporting wheel 12 is mounted on a horizontal axis 14, the longitudinal axis of which is offset from the longitudinal axis of the vertical axis 11.

At the ends of the platform 5, front and rear brackets 15 and 16 are installed (fixed) with vertical holes for swiveling with the winch traction cable 8 (front) and with the end of the spacer element 7 (rear), respectively (Figs. 1, 2, 3).

The spacer element 7 is arranged to adjust the length.

The supporting beam 6 is made with vertical holes 17 located along its length at a distance from each other. The supporting beam 6 is rigidly fixed to the wall of the reversal chamber 1 opposite the transport tunnel 2.

The second (free) end of the spacer element 7 is fixed (installed) in one of the holes 17 of the support beam 6 (Fig.1, 2, 3).

The traction rope 8 is connected to the winch (not shown in the drawing) through a stationary deflecting unit 9, mounted on the wall of the transport tunnel 2.

The proposed device operate as follows.

After installing the body of any large-sized equipment on the platform 5, the platform-equipment system is moved to the reversal chamber 1, the platform-equipment system is rotated 90 ° and then moved to the mine shaft as follows.

At the shaft of the mine or in the transport tunnel (for example, in the transport tunnel 2) connecting the reversal chamber 1 with the shaft of the mine, a traction winch is installed (not shown). The stationary deflecting unit 9 is installed (fixed) on the wall of the transport tunnel 2. The platform-equipment system is installed in the initial position in the reversal chamber 1 (Fig. 1).

An arm 16 in the rear of the platform 5 is connected to the eye of the spacer 7. The eye of the second (free) end of the spacer 7 is connected to the corresponding hole 17 of the support beam 6. The spacer 7 is installed perpendicular to the support beam 6. The end of the winch traction cable 8 is connected to the bracket 15 in the head of the platform 5.

We will turn the platform 90 ° and exit it into the transport tunnel using two examples:

Example 1 - a platform with a body of the tunnel shield (large transverse dimensions, small length and large mass (figure 5);

Example 2 - a platform with a screw conveyor (large length, small transverse dimensions and weight (Fig.6).

Example 1

The body 18 of the tunnel shield is installed on the platform (Fig. 5). The rope 8 from the winch is passed through a fixed (deflecting) block 9, mounted on the wall of the transport tunnel 2. The end of the rope 8 is fixed to the bracket 15 in the front of the platform 5. The bracket 16 in the rear of the platform 5 is connected to the eye of the spacer 7. The eye of the second ( the free) end of the spacer element 7 is connected to the corresponding hole 17 of the support beam 6 in the initial position. The spacer element 7 is installed perpendicular to the support beam 6. The platform-shield system will occupy the initial position A (Fig. 5).

When the winch is turned on, under the influence of the force in the rope 8, the movement of the platform 5 begins. When moving, all the wheels 12 of the platform 5 rotate around the vertical axes 11 and are installed in the direction of movement. Platform 5 performs a complex rotational movement and simultaneously translational towards the fixed block 9. Turn the platform - shield system at the maximum possible angle, permissible by the limited size of the underground mine for this system. The rotation of the system to the maximum possible angle will occur when the longitudinal axis of the spacer element 7, the platform-shield system, the segment of the traction rope 8 between the hinge of the bracket 15 will stand on one straight line. System platform - shield stopped in an intermediate position B (figure 5),

Next, the end of the rope 8 is disconnected from the bracket 15, the fixed block 9 is removed, moved deep into the transport tunnel 2 and fixed on its wall in another place (not shown in the drawing). The end of the rope 8 is again connected to the bracket 15 of the platform. The eyelet 16 of the spacer element 7 is also disconnected in the hole 17 of the support beam 6 (Fig. 5) and, by changing the length of the spacer element 7, its free end is fixed in the next hole 17 along the length of the support beam 6. Again, the winch is turned on and when exposed to the force of the rope 8, directed along the transport tunnel 2 to the winch drum, the platform-shield system performs another complex rotational movement around the hinges in the brackets 15 and 16 of the platform 5.

When the longitudinal axis of the spacer element 7, the platform-shield system, the segment of the traction rope 8 between the hinge of the bracket 15 will again stand on one straight line that coincides with the longitudinal axis of the transport tunnel 2, the platform-shield system will occupy the next position B (Fig. 5) and , at the same time, will be drawn into the transport tunnel 2.

U-turn system platform - shield completed.

Then the winch is turned off, the eye of the spacer element 7 is disconnected from the bracket 16 of the platform 5, the winch is turned on again and the platform-shield system is transported to the shaft.

Example 2

On the platform set screw conveyor 19 - the platform-conveyor system (Fig.6).

Since the screw conveyor has a large length, for turning the platform-conveyor system in underground workings of limited size, it is necessary to carry out intermediate turns of the system much more than when turning the platform-shield system.

The platform with the conveyor 19 is rotated from the initial position A to the first intermediate position B in the same way as with the shield body 18. For further rotation of the platform-conveyor system from the intermediate position B to the next intermediate position, the end of the traction rope 8 is disconnected from the platform bracket 15 5, the stationary block 9 is rearranged in the depth of the transport tunnel 3 and fixed on the tunnel wall in the next position 20. The eye of the spacer element 7 is disconnected in the hole 17 of the support beam 6 from the initial polo zheniya (Fig.6) and again fixed in the next hole 17 of the support beam 6 in the next position. Turn on the winch and transfer the platform-conveyor system to position B. Stop the winch and disconnect the eye of the spacer element 7 from the bracket 16 of the platform 5. Turn on the winch and pull the platform-conveyor system into the transport tunnel 2 - position G of the system. Disconnect the end of the rope 8 from the bracket 15 of the platform, remove the fixed block 9, then the end of the rope 9 is again connected to the bracket 15 of the platform 5. Turn on the winch and transport the platform 5 with the conveyor 19 to the mine shaft.

Depending on the dimensions of the equipment, the operation of the intermediate rotation of the platform-equipment system in the reversal chamber is carried out the required number of times until the platform-equipment system is completely turned 90 degrees.

Thus, the proposed device provides the implementation of the reversal of large-sized equipment in underground workings of limited size and provide their further transportation to the shaft for delivery to the surface. The proposed device also allows for the delivery of these products in the opposite direction from the shaft to the mounting chamber.

It should also be noted that the use of the utility model allows not only to turn the large-sized units of equipment of various configurations and weights in the cramped conditions of the underground space, but also to carry out its further transportation to the unloading place without the use of additional equipment.
