Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, and in particular to a drilling operation protection device. Background Technology

[0002] In the process of coal mining, drilling is a key step in obtaining underground resources. Due to the complex environment of drilling operations and the existence of various safety risks, such as well blowouts, equipment failures, and operational errors, extremely high requirements are placed on the safety protection of workers. Therefore, the construction site is protected.

[0003] Common drilling operation protection devices only include the function of enclosure, which can protect the construction site, but lack the function of adjusting the size of the enclosure. This makes it impossible to ensure that the enclosure range can be adapted to the actual construction range. It is easy for the area of ​​the construction site that needs protection to be larger than the size of the enclosure, which leads to the problem that the construction site cannot be completely enclosed, thus affecting the protection effect.

[0004] Therefore, in view of the problem that the above-mentioned drilling operation protection devices lack the function of adjusting the enclosure size and cannot be adapted to the actual construction range, resulting in insufficient protection range and affecting the protection effect, it is urgent to design a new type of drilling operation protection device. Utility Model Content

[0005] To overcome the problem that common drilling operation protection devices lack the function of adjusting the size of the enclosure, and cannot ensure that the enclosure range can be adapted to the actual construction range, it is easy for the area that needs to be protected at the construction site to be larger than the size of the enclosure. This results in the inability to completely enclose the construction site and affects the protection effect.

[0006] The technical solution of this utility model is as follows: a drilling operation protection device, including a right chamfered guard plate; it also includes a left chamfered guard plate, a driven rack, a mounting plate, a drive motor, a drive gear, and a sliding groove. A left chamfered guard plate is provided on the left side of the right chamfered guard plate. Two driven racks are symmetrically arranged on the front and rear sides of the top of the left chamfered guard plate. Two mounting plates are symmetrically arranged on the left end of the top of the front and rear sides of the right chamfered guard plate. A drive motor is provided on the top of the mounting plate on the side away from the right chamfered guard plate. The output end of the drive motor passes through the mounting plate and is connected to the drive gear. The drive gear meshes with the driven rack. Two sliding grooves are symmetrically opened on the front and rear ends of the left side of the right chamfered guard plate corresponding to the position of the left chamfered guard plate.

[0007] Preferably, a drive motor drives a drive gear to rotate in either the forward or reverse direction. The drive gear, through meshing with a driven rack, moves the left chamfered guard plate to the left or right. During this movement, a limiting plate slides inside a sliding groove. The limiting plate's size prevents the left and right chamfered guard plates from separating, thus changing the distance between them and achieving the function of adjusting the enclosure size. This addresses the problem of common drilling operation protection devices that only provide enclosure functionality, lacking the ability to adjust the enclosure size. This makes it difficult to ensure that the enclosure range matches the actual construction area, potentially resulting in the area requiring protection exceeding the enclosure size, thus hindering complete enclosure and affecting the protection effect.

[0008] Preferably, the front and rear ends of the right side of the left C-shaped guard plate are respectively inserted into the interior of two sliding grooves, and two limiting plates are symmetrically arranged at the front and rear ends of the right side of the left C-shaped guard plate.

[0009] Preferably, several ground nails are evenly spaced on the right side of the bottom of the right chamfered guard plate and the left side of the bottom of the left chamfered guard plate. Two warning lights are symmetrically installed at the front and rear ends of the top right side of the right chamfered guard plate and the front and rear ends of the top left side of the left chamfered guard plate.

[0010] Preferably, the middle of the right side of the right-hand side panel and the middle of the left side panel are both connected by hinges to protective doors, and handles are provided on the side of both protective doors away from the drive gear.

[0011] Preferably, two fixing plates are installed on the right side of the right-hand side of the right-hand side panel and the left side of the left-hand side panel, corresponding to the symmetrical protective door positions. Two air pumps are symmetrically installed on the left and right sides of the top of the fixing plates.

[0012] Preferably, the output end of the air pump is connected to a movable plate through the fixed plate, and two self-locking universal pulleys are symmetrically arranged on the left and right sides of the bottom of the movable plate.

[0013] Preferably, a step plate is provided in the middle of the side of the fixing plate away from the protective door.

[0014] The beneficial effects of this utility model are:

[0015] 1. The drive motor drives the drive gear to rotate in the forward or reverse direction. The drive gear meshes with the driven rack to move the left chamfered guard plate to the left or right. When the left chamfered guard plate moves, the limiting plate slides inside the sliding groove. The limiting plate prevents the left chamfered guard plate from separating from the right chamfered guard plate, thereby changing the distance between the right chamfered guard plate and the left chamfered guard plate, and realizing the function of adjusting the enclosure size.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a drilling operation protection device, including a right-hand shaped guard plate 1; it also includes a left-hand shaped guard plate 2, a driven rack 3, a mounting plate 4, a drive motor 5, a drive gear 6, and sliding grooves 7. The left-hand shaped guard plate 2 is located on the left side of the right-hand shaped guard plate 1. Two driven racks 3 are symmetrically arranged on the front and rear sides of the top of the left-hand shaped guard plate 2. Two mounting plates 4 are symmetrically arranged on the left end of the top of the front and rear sides of the right-hand shaped guard plate 1. The drive motor 5 is located on the top of the mounting plate 4 away from the right-hand shaped guard plate 1. The output end of the drive motor 5 passes through the mounting plate 4 and is connected to the drive gear 6. The drive gear 6 meshes with the driven rack 3. Two sliding grooves 7 are symmetrically opened on the front and rear ends of the left side of the right-hand shaped guard plate 1 corresponding to the positions of the left-hand shaped guard plate 2. The drive gear 7 is driven by the drive motor 5. Wheel 6 rotates in either the forward or reverse direction. Drive gear 6, through meshing with driven rack 3, drives left swivel plate 2 to move left or right. When left swivel plate 2 moves, limiting plate 16 slides inside sliding groove 7. The size limitation of limiting plate 16 prevents left swivel plate 2 from disengaging from right swivel plate 1, thereby changing the distance between right swivel plate 1 and left swivel plate 2. This achieves the function of adjusting the enclosure size, solving the problem that common drilling operation protection devices only include the function of enclosure, which can protect the construction site, but lack the function of adjusting the enclosure size. This makes it impossible to ensure that the enclosure range can match the actual construction range, and it is easy for the area that needs to be protected at the construction site to be larger than the size of the enclosure. This leads to the problem that the construction site cannot be completely enclosed, affecting the protection effect.

[0024] Please see Figures 2-5 In this embodiment, two fixed plates 11 are provided on the right side of the right-hand side of the right-hand side of the right-hand side of the left-hand side of the left-hand side of the left-hand side of the protective door 9. Two air pumps 12 are symmetrically arranged on the left and right sides of the top of the fixed plates 11. The output end of the air pump 12 passes through the fixed plates 11 and is connected to a movable plate 13. Two self-locking universal pulleys 14 are symmetrically arranged on the left and right sides of the bottom of the movable plate 13. A step plate 15 is provided in the middle of the side of the fixed plate 11 away from the protective door 9. The self-locking universal pulleys 14 drive the entire enclosure to the designated construction site. Then the air pump 12 is started. The air pump 12 drives the self-locking universal pulleys 14 to move upward through the movable plate 13 until the self-locking universal pulleys 14 are completely separated from the ground. At this time, the ground nails 8 are inserted into the soil, and the bottom of the right-hand side of the right-hand side of the right-hand side of the left-hand side of the left-hand side of the left-hand side of the right ...

[0025] Please see Figures 1-5In this embodiment, the front and rear ends of the right side of the left sloping guard plate 2 are respectively inserted into the interior of two sliding grooves 7. Two limiting plates 16 are symmetrically arranged at the front and rear ends of the right side of the left sloping guard plate 2. Several ground nails 8 are equally spaced on the right side of the bottom of the right sloping guard plate 1 and the left side of the bottom of the left sloping guard plate 2. Two warning lights 17 are symmetrically arranged at the front and rear ends of the top right side of the right sloping guard plate 1 and the front and rear ends of the top left side of the left sloping guard plate 2. Protective doors 9 are movably connected to the middle of the right side of the right sloping guard plate 1 and the middle of the left side of the left sloping guard plate 2 via hinges. Handles 10 are provided on the side of the two protective doors 9 away from the drive gear 6. Before installing the enclosure, it is necessary to first... The size of the enclosure is adjusted according to the scope of the construction site. The drive motor 5 drives the drive gear 6 to rotate in the forward or reverse direction. The drive gear 6, through meshing with the passive rack 3, drives the left sloping guard plate 2 to move to the left or right. When the left sloping guard plate 2 moves, the limiting plate 16 slides inside the sliding groove 7. The size of the limiting plate 16 prevents the left sloping guard plate 2 from disengaging from the right sloping guard plate 1, thereby changing the distance between the right sloping guard plate 1 and the left sloping guard plate 2. This realizes the function of adjusting the size of the enclosure and prevents the area of ​​the construction site that needs protection from being larger than the size of the enclosure, which would lead to the inability to completely enclose the construction site and affect the protection effect.

[0026] During operation, the self-locking universal pulley 14 moves the entire enclosure to the designated construction site. Before installation, the enclosure dimensions need to be adjusted according to the construction site area. The drive motor 5 drives the drive gear 6 to rotate forward or backward. The drive gear 6, through meshing with the driven rack 3, moves the left convex guard plate 2 to the left or right. During movement, the limiting plate 16 slides inside the sliding groove 7. The size limitation of the limiting plate 16 prevents the left convex guard plate 2 from moving. The right-hand sloping guard plate 1 is detached to change the distance between the right-hand sloping guard plate 1 and the left-hand sloping guard plate 2. Then, the air pump 12 is started, and the air pump 12 drives the self-locking universal pulley 14 to move upward through the movable plate 13 until the self-locking universal pulley 14 is completely detached from the ground. At this time, the ground nail 8 is inserted into the ground, and the bottom of the right-hand sloping guard plate 1, the left-hand sloping guard plate 2 and the step plate 15 are all in contact with the ground. Then, personnel walk on the step plate 15 and open the protective door 9 to enter the interior of the enclosure, thus realizing the function of adjusting the size of the enclosure.

[0027] Through the above steps, the drive motor 5 drives the drive gear 6 to rotate in the forward or reverse direction. The drive gear 6, through meshing with the passive rack 3, drives the left swivel plate 2 to move to the left or right. When the left swivel plate 2 moves, the limiting plate 16 slides inside the sliding groove 7. The limitation of the size of the limiting plate 16 prevents the left swivel plate 2 from disengaging from the right swivel plate 1, thereby changing the distance between the right swivel plate 1 and the left swivel plate 2. This realizes the function of adjusting the enclosure size, which solves the problem that common drilling operation protection devices only include the function of enclosure, which can protect the construction site, but lack the function of adjusting the enclosure size. This makes it impossible to ensure that the enclosure range can be adapted to the actual construction range, and it is easy for the area that needs to be protected at the construction site to be larger than the size of the enclosure. This leads to the problem that the construction site cannot be completely protected, affecting the protection effect.
