Description

Technical Field

[0001] This utility model relates to the field of coal mining equipment, and more specifically, to a transfer machine chute with support function. Background Technology

[0002] A typical conveyor roadway consists of roadway supports such as advance supports, end supports, transfer conveyors, crushers, self-moving transfer conveyors, and belt conveyors. The transfer conveyor and crusher can be moved in two ways: one is by using a self-moving transfer conveyor device; the other is by being pushed forward by the end supports. The transfer conveyor receives coal blocks transported by the scraper conveyor and then transfers them to the belt conveyor. The crusher connects the suspended section and the ground section of the transfer conveyor, and is responsible for crushing large pieces of coal. The advance supports and end supports provide support for the roadway, with the end supports also having the function of alternating forward movement with the transfer conveyor as mutual fulcrums. Currently, most transfer conveyor chutes only serve the function of transporting coal, a single function.

[0003] To enhance the function of the transfer machine chute, utility model patent CN219488784U discloses a coal receiving chute for a steeply inclined fully mechanized mining transfer machine. It includes a discharge chute body with a movable baffle above it. A connecting seat is positioned opposite each other on the back of the discharge chute body. The movable baffle has a through hole at its tail, located within the connecting seat and hinged to it via a pin. A jack is located at the bottom of the discharge chute body, with its base movably connected to the chute body via a connecting shaft. The jack's output shaft is connected to the movable baffle. When the movable baffle extends, it acts as a coal-blocking plate; when it retracts inward, it forms a safety roof for pedestrians, protecting them from falling. This coal receiving chute for a steeply inclined fully mechanized mining transfer machine improves both coal-blocking and safety protection. However, this structure is a passive protection mechanism and can only be used for protection in level roadways; it does not provide active support for roadways directly above the coal receiving chute. Utility Model Content

[0004] In order to improve the support capacity of the roadway directly above the transfer machine chute and improve the applicability to the roadway roof terrain, this utility model provides a transfer machine chute with support function, including several telescopic gantry frames, several telescopic anchor column assemblies, several first chute bodies and several second chute bodies, with the several first chute bodies and several second chute bodies spliced ​​together.

[0005] The telescopic gantry spans across the top of the first tank body and is used to provide overall support for the top of the first tank body.

[0006] The telescopic anchor assembly is spherically hinged to both sides of the second trench body, and is used for separate support according to the top terrain of the roadway roof of the second trench body.

[0007] Based on the above, in order to facilitate installation and assembly and to form a stable structure between the telescopic gantry and the first trough, a first support plate is provided at the bottom of the telescopic gantry. The first support plate is used to connect the first trough, and a first column socket is provided on the first support plate.

[0008] Based on the above, in order to ensure that the telescopic gantry has high stability when it is extended, the side plate of the first groove is provided with stiffening plates corresponding to the telescopic gantry. The stiffening plates are used to limit and reinforce the telescopic gantry in a clamping manner.

[0009] Based on the above, in order to facilitate overall support and improve the overall support capacity, while also having a certain degree of freedom, the telescopic gantry includes a crossbeam and a pair of first hydraulic columns. The crossbeam is hinged to the top of the pair of first hydraulic columns, and the bottom of the pair of first hydraulic columns is hinged to the first column socket.

[0010] Based on the above, in order to ensure that the telescopic gantry has high stability when it is extended, an outer cylinder is also fitted on the lower part of the pair of first hydraulic columns. The outer cylinder is hinged to the first column socket and is used to position the lower part of the first hydraulic column.

[0011] Specifically, the outer cylinder is fitted into the cavity enclosed by the stiffening plate, and the stiffening plate clamps the outer cylinder in a clamping manner to limit and reinforce the telescopic gantry frame, so that the first hydraulic column does not tip over during telescopic movement.

[0012] Based on the above, a hole reinforcement ring is provided at the top of the outer cylinder, and the hole reinforcement ring is used to reinforce the top hole of the outer cylinder.

[0013] Based on the above, in order to facilitate installation and assembly and to form a stable structure between the telescopic anchor assembly and the second groove, a second support plate is provided at the bottom of the telescopic anchor assembly. The second support plate is used to connect the second groove, and a first ball socket is provided on the second support plate for ball hinge connection of the telescopic anchor assembly.

[0014] Based on the above, in order to improve the degree of freedom of rotation of the telescopic anchor assembly, the telescopic anchor assembly includes an anchor head and a pair of second hydraulic columns. The top of the anchor head is provided with several anchor nails for holding the roadway roof, and the bottom of the anchor head is provided with a second ball socket that is ball-hinged with the second hydraulic columns.

[0015] Based on the above, ball heads are respectively provided at the top and bottom of the second hydraulic column.

[0016] In other words, to achieve separate support according to the top terrain of the tunnel roof above the second trench, the telescopic anchor assembly needs to have multiple degrees of freedom in addition to a stable installation structure. The top and bottom of the pair of second hydraulic columns in the telescopic anchor assembly are designed as ball heads, and ball sockets are designed on the anchor head and the second support plate. Through the cooperation of the ball heads and ball sockets, the top and bottom of the second hydraulic columns have a high degree of freedom, allowing them to deflect according to the top terrain of the tunnel roof during support.

[0017] This utility model has substantial features and advancements compared to existing technologies. Specifically, the utility model provides a transfer machine chute with support function. By installing a telescopic gantry frame that can support the entire machine across the chute body, and a telescopic anchor column assembly that uses hydraulic columns with anchor heads for individual support, it ensures that it can adapt to the terrain of the tunnel roof without the need for advance supports. This provides terrain-adaptive support directly above the transfer machine chute body, improving the adaptability of the transfer machine chute body to the terrain of the tunnel roof and its support capability for the tunnel.

[0018] Furthermore, by setting anchors on the top of the telescopic anchor assembly, the anchors can be pressed against the top of the machine roadway by the extension of the hydraulic column, thereby improving the holding force on the top of the machine roadway and enhancing the support stability.

[0019] Furthermore, by designing the hydraulic rods of the telescopic anchor assembly with ball-head structures at both ends and engaging them with the ball joints through a ball socket, the degree of freedom is increased, enabling it to better adapt to the undulations of the roadway roof directly above the transfer machine trough, thereby further improving the support stability.
