Description

Technical Field

[0001] This invention relates to an automatic side-knocking device for coal mine roadways, which can automatically perform side-knocking operations during underground production, belonging to the field of coal mine equipment. Specifically, it relates to an automatic side-knocking device that uses a pneumatic telescopic device to automatically strike the roadway with a striking rod, eliminating the need for personnel to hold the device high and perform side-knocking, thus reducing labor intensity and improving labor efficiency. Background Technology

[0002] "Knocking on the roof and walls" refers to the method of using crowbars, steel bars, or picks to strike the roof and sides of the mine roadway and working face before the start of underground production operations, and discovering loose rocks and layers based on the sounds produced. It is a strictly required operational standard in coal mine safety operations. However, the existing method of knocking on the roof and walls involves manual knocking with hand-held anchor rods, which is time-consuming, labor-intensive, and has uneven force. When personnel are fatigued, it is easy to knock with too little force and misjudge dangerous areas.

[0003] CN209838405U discloses a special tool for sounding the roof and walls of coal mines, comprising a head section, a connecting section, and a tail section that are detachably connected in sequence. The head section is equipped with a sounding head and a hook, while the tail section is equipped with a hand guard and an anti-slip head. The head section and the connecting section, as well as the connecting section and the tail section, are all threadedly connected and fixed with connecting nuts. This tool requires manual striking by personnel, which is quite strenuous. Moreover, the striking force is not uniformly controlled, and the detection effect is greatly affected by the personnel.

[0004] CN211081855U discloses a tool for easy assembly of side-striking and top-striking, including an operating rod and a first workpiece. The operating rod is straight and includes multiple connecting rods, with adjacent connecting rods detachably connected by a pipe clamp. The first workpiece includes a mounting rod a and a main working component. One end of the mounting rod a is fixedly connected to the main working component, and the other end is detachably connected to one end of the operating rod by a pipe clamp. The main working component includes a fork head, a hook head, a hammer head, a pry head, and a conical tip, one of which is installed on the operating rod. This tool for easy assembly of side-striking and top-striking requires continuous hand-holding by the user, which is relatively strenuous. Summary of the Invention

[0005] To improve the above situation, the present invention provides an automatic side-knocking device for coal mine roadways. This device can automatically knock the roadway with a knocking rod through a pneumatic telescopic device, eliminating the need for personnel to hold the rod high and perform the knocking operation, thereby reducing labor intensity and improving labor efficiency.

[0015] In the attached diagram

[0016] The components are: impact wheel (1), striking rod (2), fixed seat (3), protective cover (4), slide (5), pneumatic expansion joint (6), auxiliary support rod (7), caster (8), handrail (9), connecting seat (10), connecting plate (11), and main support rod (12). Detailed Implementation

[0017] The automatic side-knocking device for coal mine roadways of the present invention is implemented as follows: The automatic side-knocking device for coal mine roadways of the present invention consists of an impact wheel (1), a striking rod (2), a fixed seat (3), a protective cover (4), a slide (5), a pneumatic telescopic device (6), an auxiliary support rod (7), a caster (8), a handrail (9), a connecting seat (10), a connecting plate (11), and a main support rod (12). The fixed seat (3) is placed on top of the protective cover (4). The protective cover (4) is an arc-shaped cover. The height of one end of the protective cover (4) is greater than the height of the other end, and the width of one end of the protective cover (4) is greater than the width of the other end. The striking rod (2) is hinged on the fixed seat (3). One end of the striking rod (2) extends to one end of the protective cover (4). An impact wheel (1) is placed on one end of the striking rod (2), and the other end of the striking rod (2) extends to the other end of the protective cover (4). At one end, a groove (5) is opened on the other end of the protective cover (4). A connecting plate (11) is placed on the other end of the protective cover (4). A pneumatic telescopic device (6) is placed on the connecting plate (11). A connecting seat (10) is placed on the pneumatic telescopic device (6). The connecting seat (10) is a U-shaped seat. The connecting rod is slidably placed in the groove (5). The two ends of the connecting rod are connected to the two ends of the connecting seat (10). The connecting rod and the connecting seat (10) are combined to form a frame structure. Two main support rods (12) are provided at the bottom of one end of the protective cover (4). A handrail (9) is provided between the two main support rods (12). An auxiliary support rod (7) is provided at the bottom of the other end of the protective cover (4). A caster (8) is provided at the bottom of the auxiliary support rod (7). A caster (8) is provided at the bottom of the main support rod (12). The protective cover (4) is made of rigid material.

[0018] When in use, the staff stands under the protective cover (4) and pushes the device forward by the handrail (9). During the forward movement, the pneumatic telescopic device (6) reciprocates, thereby driving the striking rod (2) to strike up and down with the fixed seat (3) as the fulcrum. This allows for the action of knocking on the roof of the roadway without the need for staff to hold their hands high to perform the knocking operation, reducing labor intensity and improving labor efficiency. In addition, the pneumatic telescopic device (6) and the striking rod (2) make the striking force uniform, which can avoid misjudgment caused by uneven striking force.

[0019] The design of providing a handrail (9) between the two main support rods (12) allows the staff to move the main support rods (12) by pushing the handrail, thereby making the automatic door knocking device move as a whole, which is more convenient to use.

[0020] The design of having an impact wheel (1) on one end of the striking rod (2) is used. The striking rod (2) rotates around the fixed seat (3), so that the impact wheel (1) on one end of the striking rod (2) continuously strikes the roof of the tunnel. During the striking process, the impact wheel (1) is guided by rolling and can slide on the roof of the tunnel, thereby avoiding the impact wheel (1) from getting stuck during the striking process.

[0021] The protective cover (4) is designed as an arc-shaped cover. The arc-shaped cover can form an arch structure to protect the staff below and prevent the falling of gravel during the hammering process from causing injury to the staff.

[0022] The protective cover (4) is designed to be made of rigid material, which can prevent the protective cover (4) from being deformed by falling gravel, thereby extending the service life of the protective cover (4).

[0023] The design of the protective cover (4) having a height greater than that of the other end allows one end of the protective cover (4) to be close to the top of the roadway, thereby reducing the distance between the impact wheel (1) and the top of the roadway. This allows the impact wheel (1) to strike the top of the roadway quickly. At the same time, when gravel falls, the impact of the gravel's gravity is reduced, thus preventing the gravel's gravity from causing damage to the protective cover (4).

[0024] The design of the protective cover (4) having a width at one end that is greater than the width at the other end can increase the area of ​​the protective cover (4) that protects the staff, thereby preventing the staff from being injured.

[0025] The pneumatic expansion joint (6), the striking rod (2) and the fixed seat (3) are designed to work together. When in use, the pneumatic expansion joint (6) reciprocates up and down, so that the striking rod (2) rotates around the fixed seat (3), so that the impact wheel (1) on the striking rod (2) continuously strikes the roadway roof, thus completing the work of knocking on the roadway roof.

[0026] The goal is to enable the pneumatic telescopic device (6) to make the striking rod (2) automatically strike the roadway.
