Abstract

The invention relates to a lifting and transport machinery and can be used to evacuate the soil from the production area during the construction of underground structures by the method of lowering wells. The purpose of the invention is to reduce the size of the skip hoist. The latter contains a skip 1 with two wheels 2, a drive system with flexible traction bodies 3 and a device for unloading a skip with hard triangles 5. Skip 1 is equipped with slots 8, which, when the skip moves to the place of unloading, come into contact with gripping elements 7 of a hard triangle 5. At the same time, a rigid fixation of the skip relative to the pivoting elements is ensured, and they further move together. 1 silt

Description

The invention relates to hoisting machinery, in particular to skip hoists, and can be used to evacuate soil from the production zone during the construction of underground structures by the method of lowering wells. When evacuating soil from a drain well, the dimensions of the Lift are of great importance, since the latter is installed inside a limited volume of the well, where various equipment for the development and evacuation of soil is located. In addition, the lowering wells are mounted with belts, therefore, by deepening it is necessary to build up rail tracks each time and strengthen their curved section, as well as frames with grips on the upper end of the lowering well.

The purpose of the invention is the reduction of the size of the skip hoist.

The drawing schematically shows a skip lift.

The skip elevator comprises a skip 1 equipped with two wheels 2, a drive system (not shown) for moving the skip 1 by means of flexible traction bodies (ropes) 3, and also a skip unloading device, which is mounted on the supporting frame 4. mounted on the upper end of the lowering well. The skip unloading device includes two rigid triangles 5 pivotally mounted by one of its vertices on the frame 4. On the other two vertices of the triangles 5 there are guide pulleys 6. The triangles are equipped with gripping elements 7 for the skip 1, on the back wall of which there are mating slots 8 In addition, the skip 1 is equipped with blocks 9 for flexible traction bodies 3. For a directed discharge of material from the skip, a tray 10 is installed at the end of the lowering well.

Skip hoist operates as follows.

When you turn on the winch (not shown), the ropes 3, winding on the winch drum and 5 around the blocks 9 and the guide pulleys 6, pull the loaded skip 1 up. Wheel 2 skip 1 while moving along the concrete wall of the lowering well.

In the extreme upper position of the skip 10, the gripping elements 7 enter the nests 8 of the skip 1. With further winding of the rope 3 onto the winch drum (not shown), the skip 1 together with the triangles 5 begins to move along an arc of a circle. At the end of the 15th turn, the rope 3 leaves the streams of the guide pulleys 6. The extreme positions of the triangles 5 are limited by stops (not shown). In the highest position, the skip 1 is unloaded into the tray 10.

After unloading the skip 1, the winch drive is reversed, the rope 3 is released and the skip 1 with triangles 5 is returned to its original position under its own weight.

Claims (1)

Claim A skip hoist comprising a skip equipped with wheels, connected to a 30 drive for moving it by means of flexible traction bodies enveloping the guide pulleys, and a skip unloading device equipped with gripping elements for the latter, characterized in that, in order to reduce the dimensions, the unloading device includes two rigid triangles with guide pulleys located on their tops, while the skip is equipped with blocks for flexible traction elements, and nests are made on its rear wall for placement in them are gripping elements.
