Description

Technology area

The utility model relates to mining engineering, namely to the loading section of a roadheader.

State of the art

It is known from the prior art, taken as the closest analogue, a loading section of a roadheader containing a conveyor section frame, to the sides of which holders are attached from the inside, in which open grooves are coaxially made with the possibility of installing the journals of the bypass head in them, with each trunnion fixed in the corresponding holder with one fastening element. The mating surfaces of the bypass head trunnions and the holders' grooves are V-shaped. The axes of the grooves in this design are parallel to the horizontal axis of the frame of the conveyor section [Roadheader KPD.00.00.000-22 Technical description, March 2019, p. 10-11. https://public.docs. openprocurement. org / get / 8e27870b35b436 1850f4278c0306474? KeyID = 52462340 & Signature = 2zWbXZhJbN% 2FUfroIrK 8KaGE6A6SNMAQM2rl Gaq5ncWYtOSoLlWknpYZ QwTT426cK8O0u CZraoScqBU295uo Dg% 253D% 253D].

The disadvantage of this design is the complexity of mounting and dismounting the bypass head from the frame of the conveyor section. The location of the axis of the grooves of the holders parallel to the horizontal axis of the frame of the conveyor section makes it difficult to access the fasteners. To remove them, it is necessary to dismantle part of the scraper chain in the area of the bypass head. With such an arrangement of the grooves of the holders, when attaching the bypass head, additional efforts must be made to hold it.

A task

The utility model is based on the following task: to create a structure for fastening the bypass head of the loading section of a roadheader, which ensures the convenience of its mounting / dismounting.

As a result of solving the problem, a technical result will be obtained, which consists in ensuring the convenience of mounting / dismantling the bypass head of the loading section of the roadheader.

Achievement of the technical result will ensure the consumer properties of the utility model: reduction of time losses for assembly / disassembly of the bypass head of the loading section of the roadheader.

Disclosure of a technical solution

In the known from the prior art, the loading section of the roadheader, containing the frame of the conveyor section (1), to the sides (2, 3) of which holders (4, 5) are attached from the inside, in which open grooves (6) are made coaxially with the possibility of installation in them pins (7, 8) of the bypass head (9), while each pivot (7, 8) is fixed in the corresponding holder (4, 5), at least one fastening element (10), in accordance with the technical solution proposed axles (X) grooves (6) in each holder (4, 5) should be made inclined to the vertical plane with the possibility of free removal of the bypass head (9) from the frame of the conveyor section (1).

In addition, it is proposed:

- the mating surfaces of the pins (7, 8) of the bypass head and open slots (6) of the holders (4, 5) are cylindrical;

- close each open groove (6) with a cover (11) introduced into the structure with a through hole for the fastening element (10), while the surface (12) of the cover (11), mating with the journal (7, 8), is cylindrical.

The causal relationship between the newly introduced essential features of the formula and the claimed technical result is explained as follows.

The arrangement of the axes (X) of the grooves (6) of the holders (4, 5) at an angle to the vertical plane will allow easy access to the fasteners (10) for mounting / dismounting the bypass head (9). Removal of the bypass head (9) during dismantling will occur along a trajectory with a deviation from the vertical plane in the range of 0 ° -50 °, therefore, there is no need to dismantle the scraper chain in the area of the bypass head (9), it is enough to disconnect the chain.

Industrial applicability

The implementation of the technical solution is shown in Fig. 1-3, which are not exclusive, but clearly demonstrate the possibility of achieving the claimed technical result.

The loading section of the roadheader is a frame of the conveyor section (1) with sides (2, 3), to which holders (4, 5) are attached from the inside. Each of the holders (4, 5) is made along an open groove (6) coaxially to each other with the possibility of installing the pins (7, 8) of the bypass head (9) (Fig. 1). Each trunnion (7, 8) is fixed in the corresponding holder (4, 5) by at least one fastening element (10). The holders (4, 5) are attached to the sides of the frame (2, 3) (for example, by welding) in such a way that the axes (X) of the grooves (6) in the holders (4, 5) are inclined to the vertical plane, which will provide free removal of the bypass head (9) from the frame of the conveyor section (1) (Fig. 2).

In the example shown, the mating surfaces of the pins (7, 8) of the bypass head (9) and open slots (6) of the holders (4, 5) are cylindrical. Each open groove (6) is closed by a cover (11) introduced into the structure with a through hole for the fastening element (10), while the surface (12) of each of the covers (11), mating with the corresponding trunnion (7, 8), is also made cylindrical ...

To replace the bypass head (9), before dismantling it, a scraper chain (not shown in the figures) is disconnected, which covers the bypass head in the 180 ° sector (transition of an idle branch to a working one). The installation of the new bypass head is performed by moving obliquely in the 0 ° -50 ° sector until the pins (7, 8) touch the open slots (6), made with a deviation from the vertical plane in the range of 0 ° -50 °. Because the axes (X) of the slots (6) in the holders (4, 5) are made obliquely to the vertical plane, the bypass head (9) is easily, mainly due to its own weight, lowered by the pins (7, 8) along the open part of the slots (6) of each holder (4, 5) to the end point of mating of the surface of the pins (7, 8) of the bypass head (9) and open slots (6) of the holders (4, 5). In the future, the need to hold the bypass head (9) in the hands is eliminated until it is secured. Then the open part of each groove (6) is closed by a cover (11) with a through hole introduced into the structure, and the entire assembly is fixed with a fastening element (10) (Fig. 3).

Dismantling is carried out in the reverse order.

Thus, the claimed technical result is achieved: ensuring the convenience of mounting / dismounting the bypass head of the loading section of the roadheader.

For a specialist, from the previous description, some modifications of the loading section of the roadheader follow, which fall within the scope of protection of additional claims of the utility model.
