Description

Technical Field

[0001] This utility model relates to the field of coal mine support equipment, specifically to a side support mechanism with crushing function and a hydraulic support. Background Technology

[0002] The working face has a large volume of large pieces of gangue. These large pieces are transported to the machine head position via scraper conveyors and need to be crushed before entering the transfer conveyor. Currently, the common method for crushing large pieces of gangue at the working face is to use a hand-held pneumatic pick, climbing onto the conveyor to crush them. This method poses safety hazards to the operators if there is coal wall spalling or roof collapse. Another method is to install the crushing mechanism on the transfer conveyor or on the base of the end support. However, due to the limited length of the mechanical arm of the crusher hammer, there may be situations where it cannot reach the large pieces of gangue at the working face machine head position. Installing the crusher hammer on the end support base requires reserving a certain amount of installation space in the pedestrian walkway, leading to congestion in the pedestrian walkway.

[0003] Patent application CN115199312A discloses a side guard plate and hydraulic support with crushing function, including a body, a crushing device, and a limiting block. The body has a first mounting member and a second mounting member; the first mounting member is located at the top of the body, and the second mounting member is located on the outer surface of the body. The limiting block is located at the inner end of the body along a first preset direction, and the limiting block has a through hole that penetrates the limiting block along the first preset direction. The crushing device is movably disposed inside the body between a crushing position and a retraction position. This side guard plate with crushing function can crush loose coal or large pieces of coal that have fallen, maximizing transportation efficiency and reducing labor intensity. However, the disclosed structure of this side guard plate with crushing function requires an additional crushing device jack to drive the crushing rod to move, making the operation cumbersome. Utility Model Content

[0004] In order to expand the function of the side guard plate, save the installation space of the breaker hammer, and improve the convenience and crushing efficiency of the crushing face gangue, the technical solution adopted by this utility model is: a side guard mechanism with crushing function, including a telescopic top beam and a side guard plate hinged to the telescopic top beam, and a side guard plate unfolding cylinder is provided between the telescopic top beam and the side guard plate, the side guard plate unfolding cylinder is used to unfold the side guard plate. The side panel includes an inner side panel and an outer side panel, and the inner side panel and the outer side panel are hinged together; The outer protective plate is provided with an installation limiting groove, and a breaker hammer is detachably installed in the installation limiting groove, with the outer end of the breaker hammer extending out of the outer protective plate; An outer guard plate unfolding cylinder is provided between the inner guard plate and the outer guard plate. The outer guard plate unfolding cylinder is used to change the working position of the breaker by unfolding the outer guard plate.

[0005] Beneficial effects: When the side guard plate is in the unfolded state, the breaker can be sent to the large pieces of gangue on the working face, making it convenient to use the breaker plate itself to crush the large pieces of gangue on the working face, reducing labor intensity, and also reducing the space occupied.

[0006] Based on the above, a pair of hydraulic cylinder hinge seats are respectively provided on the inner side of the outer protective plate and the inner side of the inner protective plate. The mounting limiting groove is provided between the pair of hydraulic cylinder hinge seats on the outer protective plate, and a plurality of assembly holes are provided on the mounting limiting groove.

[0007] Beneficial effects: It can ensure the stability and operational safety of the hydraulic breaker when mounted on the outer protective plate.

[0008] Based on the above, the length of the inner protective plate is greater than the length of the outer protective plate.

[0009] Beneficial effect: It enables the outer cladding to have a folding function without reducing the support capacity of the inner cladding.

[0010] Based on the above, the central axis of the hydraulic breaker coincides with the central axis of the outer protective plate.

[0011] Beneficial effects: It can ensure that the hydraulic breaker is installed in a centered position, increasing the stability of the installation and the stability during operation.

[0012] Based on the above, the inner protective plate and the outer protective plate are hinged together by a hinge shaft, and the top of the breaker is located below the hinge shaft between the inner and outer protective plates, so that the outer protective plate is in a folded state and the top of the breaker does not interfere with the inner protective plate.

[0013] Beneficial effect: It can prevent interference between the top of the breaker and the inner guard plate when the outer guard plate is folded.

[0014] Based on the above, a pair of side guard plate deployment cylinders are provided on the telescopic top beam, and the telescopic ends of the pair of side guard plate deployment cylinders are hinged to the inner guard plate.

[0015] Based on the above, the telescopic end of the telescopic top beam is provided with a side plate hinge beam for hinged to the side plate, and the telescopic top beam is provided with a top beam telescopic cylinder. The other end of the side plate unfolding cylinder is hinged to the side plate hinge beam so that the side plate unfolding cylinder and the side plate move together with the side plate hinge beam.

[0016] Beneficial effects: It can simultaneously utilize the coordinated action of the top beam telescopic cylinder, the side guard plate unfolding cylinder, and the outer guard plate unfolding cylinder to control the position of the hydraulic breaker and expand the working area of ​​the hydraulic breaker.

[0017] This utility model also provides a hydraulic support, which is equipped with the above-mentioned side protection mechanism with crushing function.

[0018] This utility model has substantial features and advancements compared to existing technologies. Specifically, it provides a sidewall support mechanism with a crushing function. By designing the sidewall support plate as a combination of an inner support plate, an outer support plate, and an outer support plate deployment cylinder, a breaker hammer is installed on the outer end of the outer support plate, with the hammer head extending beyond the edge of the outer support plate. This allows the breaker hammer to be delivered to large pieces of rock at the working face when the sidewall support plate is in the deployed state, facilitating the crushing of these large rocks and reducing labor intensity. Since the breaker hammer is mounted on the sidewall support plate, it does not obstruct pedestrian walkways, saving tunnel space. Furthermore, by mounting the breaker hammer on the outer support plate within the sidewall support plate, the outer support plate deployment cylinder can control the deployment and folding of the outer support plate and breaker hammer together, making operation convenient.

[0019] Furthermore, by installing the hydraulic breaker on the outer protective plate within the support plate, the folding fit between the outer and inner protective plates can be utilized to fold the hydraulic breaker along with the outer protective plate, thus avoiding interference during the support process.

[0020] Furthermore, by using the hinged beam of the side guard plate to connect the side guard plate to the telescopic end of the telescopic top beam, the breaker hammer installed on the side guard plate can be moved, thereby increasing the movement range of the breaker hammer and expanding its working range.

[0021] Furthermore, by setting a mounting limiting groove on the outer protective plate and opening several assembly holes in the mounting limiting groove, the position of the breaker hammer can be limited, thereby improving installation efficiency and installation stability.
