The hanging and lifting device, in particular, can be characterized by the fact that it additionally contains control valves located in the pump power unit, on the fluid supply line.

The hanging and lifting device, in particular, can be characterized in that it additionally contains hollow support pipes of rectangular cross section, while the support pipes are fixed on the base and contain additional small reinforcing plates fixed on the body, as well as additional large reinforcing plates fixed on the connecting frame.

The hanging and lifting device, in particular, can be characterized by the fact that the high-pressure sleeves of the hydraulic jacks are located inside the housing.

The hanging and lifting device may in particular be characterized in that it further comprises a lubrication point.

The figure schematically shows a device for hanging and lifting mining equipment, with different heights of lifting supports, where the numbers indicate the following:

1. case;

2. retractable support;

3. connecting frame;

4. locking mechanism;

5. extensions;

6. base;

7. support pipes;

8. small reinforcing plates;

9. large reinforcing plates.

The presented device for hanging and lifting mining equipment is arranged as follows.

The device for hanging and lifting mining equipment consists of two telescopic supports with built-in hydraulic jacks connected by a connecting frame. The telescopic support consists of a housing (1), which is a metal structure with a hydraulic jack of the appropriate load capacity installed inside (not shown in the figure). The housing is located on the base (6). Inside the housing there is a retractable support (2) fixed on the jack rod (not shown in Fig.). Each housing has two ratchet locking mechanisms (4). Two telescopic supports are interconnected by a connecting frame (3). Extensions (5) are provided in the system kit. The device for hanging and lifting mining equipment allows the use of retractable supports both jointly and individually

The presented device for hanging and lifting mining equipment operates as follows

The hanging device is placed under the vehicle using a forklift or forklift. To do this, there are fastenings for the forks of a hydraulic trolley or a forklift, both on the connecting frame, to move the entire system as a whole, and on each telescopic support. Next, the operator activates the hydraulic jacks. The jack stem begins to extend, also extending the support associated with it. The support, resting against the body of the dump truck, begins to lift it. Upon reaching the required lifting height, the hanging and lifting device is locked using locking mechanisms, which can be made in the form of ratchet locking mechanisms. The ratchet mechanism ensures the reliability of the operation of the device, due to the reliability of holding the support in the extended state. As the load increases, the spring-loaded jaws lock into the teeth on both sides of the jack, turning single and double telescopic legs into support legs. At the end of the work, the ratchet locking mechanism is released before the outriggers are lowered, the outriggers are lowered.

The double and single telescopic legs of the hanger provide flexible and heavy-duty heavy-duty jack and leg. Height-adjustable extensions provide discrete lifting heights, while the suspension system allows the lifting height to be adjusted smoothly over a wide range of heights, increasing operational reliability through a wide range of applications. The set of adjustments allows one device to carry out both lifting and hanging of various mining equipment, both with the whole of both supports, and with only one vertical retractable support. This ensures the use of one device instead of two: a rolling jack and adjustable stands. Less need to replace devices when servicing mining equipment generally increases reliability due to fewer service device change cycles. Also, the connecting frame has the ability to adjust the center distance between the retractable supports.

To complement the hanging device, a pumping power unit is used, allowing the operator to lift both columns simultaneously or separately, while changing the lifting height of each column to avoid tilting when lifting. In the pump power unit, on the line for supplying fluid to the piston cavity of the jack, adjusting valves are provided for manual synchronization of the operation of the hydraulic cylinders, which increases the reliability of operation due to the possibility of fine tuning.

In addition, the connecting frame can be placed on large reinforcing plates (9) that provide additional support.

In this case, large reinforcing plates can be fixed to the support pipes (7) of rectangular cross section. Rectangular support tubes provide greater support and stability to the unit. The body can be attached to small reinforcing plates (8), which are also designed to provide additional fixation. Small reinforcing plates, in turn, are fixed to the support pipes, and the support pipes are attached to the base. Thus, providing additional fixation of the device elements, as well as their additional support, undoubtedly increase the reliability of operation, as they increase the reliability of the structure.

High-pressure hoses (not shown in the figure) are placed inside the housing, which ensures their safety from possible external damage and increases the reliability of operation. In addition, the units of the device contain a lubrication point (not shown in Fig.), which is designed for timely lubrication of the moving parts of the mechanism, which ensures their durability and, accordingly, the reliability of the entire structure as a whole.

The body and the retractable support are made of metal pipes and represent a “pipe-in-pipe” design, coaxially located relative to each other. The design of the case in the form of a solid pipe (with the presence of technological and mounting holes) provides reliable protection of the retractable support located inside with a hydraulic jack and assemblies that ensure their performance. The retractable support is also realized as a one-piece tube. The one-piece design allows to withstand large mechanical loads, which also ensures the reliability of the device.

Thus, the use in the design of the device for hanging and lifting quarry equipment, the body and retractable vertical supports, made in the form of pipes of circular cross section coaxially arranged relative to each other, where the retractable support is made in the form of a single pipe, makes it possible to achieve the claimed technical result, namely, an increase reliability of the device.
