Description

Technical Field

[0001] The utility model relates to the technical field of coal bunker coal machines, in particular to a structure in which a coal feeder at the lower opening of a coal bunker is installed in a forward direction and a locking beam is added. Background Art

[0002] Due to the limited space at the lower opening of the coal bunker, the original design was for the coal feeder to be fixed with anchor bolts. The 2# coal feeder and the belt conveyor run in opposite directions. When the 2# coal feeder is discharging coal, the accumulation of coal blocks can easily cause belt conveyor accidents. At the same time, the tunnel is deformed, and the coal feeder and the lower opening of the coal bunker are misaligned, which can easily cause coal to leak out of the misaligned area, increase the workload of employees, and lead to major hidden dangers such as coal accumulation causing the belt conveyor to deviate. Utility Model Content

[0003] The utility model aims to solve the problems existing in the background technology and provides a structure in which a coal feeder at the lower opening of a coal bunker is installed in a forward direction and a locking beam is added.

[0004] In order to solve the above technical problems, the technical solution provided by the utility model is: a structure in which a coal feeder at the bottom of a coal bunker is installed in a forward direction and a locking beam is added, comprising a coal bunker, a first coal feeder and a second coal feeder, a plurality of first legs being arranged at the bottom of the first coal feeder, a plurality of second legs being arranged at the bottom of the second coal feeder, the bottoms of the first legs and the second legs being fixed on the ground by anchor bolts, the coal bunker being connected to the first coal feeder by a first locking beam, and being connected to the second coal feeder by a second locking beam.

[0005] Preferably, the first supporting leg and the second supporting leg are arranged outside the frame of the belt conveyor.

[0006] Preferably, the second coal feeder runs in the direction of the belt conveyor.

[0007] Preferably, the running direction of the first coal feeder and the second coal feeder are both from the second coal feeder to the first coal feeder.

[0008] Preferably, the first locking beam and the second locking beam are both 40#B locking beams.

[0009] The utility model has the following advantages: adjusting the casting position of the lower opening of the coal bunker to ensure that the two coal feeders have the same running direction; at the same time, installing a 40#B I-beam locking beam at the lower opening of the coal bunker to connect the coal feeder and the locking beam, thereby ensuring the reliability of the lower opening of the coal bunker, and ensuring the safe operation requirements of the coal feeder and belt conveyor from the source, thereby avoiding major safety hazards of the belt conveyor system caused by coal accumulation under the second coal feeder.

[0014] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0015] The preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0016] Example

[0017] In conjunction with the accompanying drawings, a structure in which a coal feeder at the bottom of a coal bunker is installed in a forward direction and a locking beam is added, comprises a coal bunker 100, a first coal feeder 101 and a second coal feeder 201, a plurality of first legs 102 are arranged at the bottom of the first coal feeder, a plurality of second legs 202 are arranged at the bottom of the second coal feeder, the bottoms of the first legs and the second legs are fixed on the ground 500 by anchor bolts 300, the coal bunker 100 is connected to the first coal feeder by a first locking beam 103, and is connected to the second coal feeder by a second locking beam 203.

[0018] As a preferred implementation scheme of this embodiment, the first supporting leg and the second supporting leg are arranged outside the frame of the belt conveyor.

[0019] As a preferred implementation scheme of this embodiment, the running direction of the second coal feeder is toward the running direction of the belt conveyor.

[0020] As a preferred implementation scheme of this embodiment, the running directions of the first coal feeder and the second coal feeder are both from the second coal feeder to the first coal feeder.

[0021] As a preferred implementation scheme of this embodiment, the first locking beam and the second locking beam are both 40#B locking beams.

[0022] 400 is the upper and lower tapes of the tape machine.

[0023] During the specific implementation of the utility model, the running direction of the second coal feeder is opposite to that of the belt conveyor. When coal accumulates at the coal dropping point, the belt will be damaged. When encountering coal gangue accumulation, the belt will be severely damaged, and the safe operation of the belt conveyor will not be utilized. The 2# coal feeder is changed to forward direction to avoid the above problems and ensure that the reliability of the safe operation of the belt conveyor is improved from the source.

[0024] Adding a locking beam to the coal feeder is beneficial to the installation and fixation of the coal feeder; when the tunnel is affected by mining, it can prevent the deformation of the bottom plate from causing misalignment between the coal feeder and the lower opening of the coal bin, thereby ensuring the safe operation of the coal feeder.

[0025] Where double coal feeders are installed front and back under the same coal bunker, the coal feeders are installed in the forward direction; a locking beam is added to the vibrating coal feeder at the lower opening of the coal bunker to improve the safe operating conditions of the coal feeder and reduce maintenance costs.

[0026] Note: 1. The center distance of the lock mouth at the bottom of the coal bunker is expanded from the original 4600mm to 5000mm, and the two coal feeders at the bottom of the coal bunker are changed from back-to-back installation to forward installation to avoid the accumulation of coal gangue between the second coal feeder and the belt conveyor, which may cause damage to the belt and even major hidden dangers to the belt conveyor.

[0027] 2. Install a locking beam at the lower opening of the coal bunker. The locking beam is pre-buried in the coal bunker foundation to increase the strength of the locking beam. The coal feeder is installed under the locking beam, which is conducive to the installation and maintenance of the coal feeder. When the tunnel floor is deformed, it will not affect the gap between the coal feeder and the coal bunker and cause coal spillage, thereby achieving the inherent safety of the lower opening of the coal bunker.

[0028] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-described embodiments only express several implementation methods of the utility model, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
