Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic support advance support settings, specifically, to an advance support device that moves automatically together with a transfer machine. Background Technology
[0002] In coal mining faces, coal is typically mined and chuted using coal mining machines, and transported by scraper conveyors and transfer conveyors. To facilitate the continuous advancement of the coal mining face, self-moving devices are usually installed on the transfer conveyors to ensure that they move with the face. However, the coal mining face roadways require advanced support, but space is limited in the area where the transfer conveyor self-moving device is located, making it impossible to install conventional advanced supports. Although unit supports, due to their small size and light weight, can be used in this area, they cannot move independently.
[0003] Utility model patent CN222276705U discloses a self-moving advanced support system that moves together with a transfer machine. It includes a support assembly and a first drive assembly. The first telescopic member has two ends connected to the transfer machine and a first unit support, respectively. The second telescopic member has two ends connected to the transfer machine and a second unit support, respectively. The third telescopic member has two ends connected to the first and third unit supports, respectively. The fourth telescopic member has two ends connected to the second and fourth unit supports, respectively. The fifth telescopic member has two ends rotatably connected to the first and second unit supports, respectively. The sixth telescopic member has two ends rotatably connected to the third and fourth unit supports, respectively. During the detachment and movement of any unit support, either the fifth or sixth telescopic member dynamically connects it to one of the other three unit supports. This self-moving advanced support system that moves together with the transfer machine solves the problem of easy tipping during the detachment and movement of a single unit support. However, the disclosed structure of the self-moving advanced support that moves together with the transfer machine requires the unit support to be moved through a combination of hydraulic cylinders and connecting devices. This necessitates the design of a corresponding connecting device on the loader, resulting in defects such as poor versatility, complex structure, and cumbersome control procedures. Utility Model Content
[0004] In order to improve versatility and simplify the self-movement control steps and structure when using a transfer machine to move unit supports, the technical solution adopted by this utility model is: an advanced support device that moves together with the transfer machine and is installed next to the transfer machine, characterized in that: it includes several pairs of unit supports, and each pair of unit supports is movably connected to the transfer machine through a connecting component;
[0005] The connecting assembly includes a crossbeam, with an upper connecting arm on the upper side of the crossbeam for connecting to the side wall of the transfer machine, and a pair of connecting seats on the lower side of the crossbeam. Connecting ear plates are respectively hinged to the connecting seats, and one end of the connecting ear plate is hinged to the unit bracket.
[0006] Based on the above, the upper connecting arm is located on the side of the crossbeam closer to the transfer machine, and the connecting seat is located on the side of the crossbeam away from the transfer machine.
[0007] Beneficial effects: By distributing the upper connecting arms and connecting seats on both sides of the crossbeam, a certain width of gap can be formed between several pairs of unit supports and the transfer machine, avoiding interference and collision during the self-movement process.
[0008] Based on the above, the connecting seat includes a connecting rod fixedly connected to the crossbeam, and a pair of triangular connecting plates disposed on the connecting rod, wherein the connecting ear plate is hinged to one corner of the lower end of the triangular connecting plate.
[0009] Beneficial effects: By designing the connecting seat as a connecting rod and a triangular connecting plate, the connection is strengthened on the one hand, and on the other hand, it is easy for the connecting ear plate to be hinged downward to the bottom of the unit support, ensuring that the unit support has a certain degree of freedom during the self-movement process, and can adapt to the terrain at the bottom of the tunnel by swinging the connecting ear plate up and down.
[0010] Based on the above, the pair of triangular connecting plates are arranged parallel to each other.
[0011] Based on the above, the unit support includes an advanced support base and an advanced support telescopic rod disposed on the advanced support base, and a pair of connecting ear plates are hinged to the advanced support base.
[0012] Based on the above, the connecting ear plate is arranged parallel to the crossbeam, and the upper connecting arm is arranged perpendicular to the crossbeam.
[0013] Based on the above, a plurality of upper connecting arms are provided on the upper side of the crossbeam, and the spacing between the plurality of upper connecting arms is different.
[0014] Beneficial effects: By setting multiple upper connecting arms with different spacing on the upper side of the crossbeam, the connection between the crossbeam and the transfer machine can be strengthened. On the other hand, the safety during the self-moving process can be improved according to the installation position and stress conditions.
[0015] This utility model represents a substantial advancement over existing technologies. Specifically, it provides a self-moving advance support device that moves alongside a transfer machine. Several pairs of unit supports are movably connected to the transfer machine via a connecting assembly. The connecting assembly is designed as a crossbeam, upper connecting arm, connecting seat, and connecting ear plate. This allows the unit supports to move automatically when the transfer machine moves, eliminating the need for additional control. This simplifies the existing structure and operation that requires controlling a moving cylinder for self-movement, improving structural versatility and simplifying the self-movement control steps. Furthermore, the hinged connection between the connecting ear plate and the unit supports ensures a degree of freedom during self-movement, allowing the unit supports to adapt to the terrain at the bottom of the tunnel by swinging the connecting ear plate up and down.
