Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining machinery technology, specifically to an underground drilling rig platform that can adapt to slope and maintain the level of the working platform. Background Technology
[0002] Drilling rigs are essential tools for drilling operations in metal mine exploration, ore body extraction, and tunnel support. Drilling rigs rely on manual loading and unloading of drill rods, requiring close coordination among multiple operators. When operating on slopes, if the work platform tilts, improper operation or lack of coordination often leads to equipment overturning or personnel falling risks. Furthermore, drilling rigs require frequent movement; traditional drilling rig platforms present difficulties in movement and turning in low or narrow tunnels, failing to meet the requirements for portability and stability.
[0003] Chinese utility model patent CN 209354058U discloses a multi-functional foldable pneumatic drilling machine. The drilling machine is mounted on a chassis with rollers at the bottom, and a support platform is located above the chassis. A telescopic mechanism between the two allows for the lifting and lowering of the support platform. A rotating platform above the support platform enables drilling at multiple angles, heights, and depths. However, it has the following drawbacks: 1. The rollers are prone to jamming on uneven ground, gravel piles, or slopes, resulting in poor terrain adaptability. 2. Despite including multiple lifting and rotating mechanisms, the folded size remains large, making it difficult to transport in narrow passages. Furthermore, the device is difficult to manufacture, heavy, and has poor portability. Utility Model Content
[0004] This utility model proposes an underground drilling rig platform, the purpose of which is to solve the problems of poor terrain adaptability, large size and difficulty in transportation in narrow tunnels, as well as complex structure, high processing and manufacturing difficulty, heavy weight and poor portability of existing drilling rig platforms.
[0005] The technical solution of this utility model is as follows:
[0006] A downhole drilling rig platform includes a working platform, with a ladder frame rotatably connected to the left and right sides below the working platform. Each ladder frame includes two legs positioned front and rear, with a footboard fixed between the two legs. Diagonal braces are hinged between the working platform and the second ladder frame, with the bottom of each brace rotatably connected to a leg and the top of each brace rotatably connected to the corresponding side of the working platform. Locking devices are connected to the legs. Each leg of the second ladder frame includes a fixed support column. The side wall of the fixed support column has a strip-shaped groove arranged along its axial direction, and multiple locking slots perpendicularly communicating with the strip-shaped groove are arranged along its length. A telescopic rod extending from the lower end of the fixed support column is slidably disposed inside the fixed support column, and a fixing pin is connected to the upper part of the telescopic rod for engaging with the locking slots to fix the extension length of the telescopic rod.
[0007] As a further improvement of this utility model, the locking component includes a fastening pin whose inner end is fixed on the support leg, and a slotted opening at the outer end of the fastening pin. A long strip-shaped locking piece is connected inside the slotted opening. One end of the locking piece is arc-shaped, and a strip-shaped hole is opened on the locking piece. The locking piece is rotatably connected to the fastening pin through a short pin that passes through the strip-shaped hole and is fixed between the inner walls on both sides of the slotted opening.
[0008] As a further improvement of this utility model, a connecting plate is fixed to the upper end of the ladder frame, and the front and rear ends of the connecting plate are respectively fixed to the support legs on the corresponding sides. The connecting plate is provided with a bushing for forming a rotating pair with the rotating shaft fixed to the bottom surface of the work platform.
[0009] As a further improvement of this utility model, the treads are arranged at equal intervals, and the number of treads in the second ladder is greater than the number of treads in the first ladder.
[0010] As a further improvement of this utility model, the legs and steps of the first ladder frame are made of angle steel.
[0011] As a further improvement of this utility model, the working platform has a hollow structure with multiple rectangular grooves arranged side by side in parallel along the length direction; multiple reinforcing ribs are welded to the top surface of the working platform, and the reinforcing ribs are arranged in parallel with each other and their direction is perpendicular to the length direction of the rectangular grooves.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] (1) This device achieves multi-level height adjustment of the second ladder frame through strip grooves, fastening grooves and fixing pins, so that the working platform can effectively compensate for the slope difference of the underground inclined roadway or uneven ground, such as achieving multiple adjustment of 0°, 4°, 8°, 12° and 16°, ensuring that the working platform can maintain a basically horizontal state under various complex terrains, providing a safe and reliable working reference surface for drilling rig operators and equipment. At the same time, by setting diagonal braces and locking parts, after the platform is unfolded and leveled, the relative angle between the diagonal braces and the ladder frame can be quickly and firmly locked to form a stable triangular support structure, which greatly enhances the overall rigidity and anti-overturning stability of the entire platform in the working state, and can greatly reduce the risk of equipment overturning and personnel falling.
[0014] (2) This device achieves the folding capability of the drilling platform by rotating the first and second ladder frames on the left and right sides below the working platform, which can be quickly folded and retracted when not in operation. By combining lightweight and folding, the entire drilling platform is lightweight and compact, making it extremely convenient to move and transport in narrow and low underground roadways, thus meeting the operational needs of frequent underground movement.
[0015] (3) By setting up a hollow structure working platform, the weight of this device is greatly reduced. The top surface of the working platform is vertically welded with evenly distributed reinforcing ribs. This not only compensates for the strength loss that the hollow structure may cause, but also significantly enhances the rigidity and load-bearing capacity of the working platform. At the same time, the top reinforcing ribs also increase the friction of the platform surface, effectively preventing personnel and equipment from slipping and improving operational safety.
[0016] (4) The second ladder of this device has more steps than the first ladder. This design takes into account that when working on an actual sloping ramp, the second ladder is located on the bottom side of the ramp, and personnel may need more steps to adapt to a greater height difference or to provide more stable support. This design ensures that the bottom step height is appropriate, effectively prevents the risk of falling, and further protects personnel safety. Attached Figure Description

Detailed Implementation
[0023] The technical solution and effects of this utility model will be described in detail below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
[0024] like Figure 1 As shown, an underground drilling platform includes a working platform 1. A ladder frame is rotatably connected to the left and right sides below the working platform 1. Each ladder frame is rotatably connected to a rotating shaft fixed to the bottom of the working platform 1 via a connecting plate fixed at its top.
[0025] To reduce the weight of the work platform 1, and to increase the friction on the upper side of the work platform 1 and improve the stability of the structure, the work platform 1 is a hollow structure with several rectangular grooves 12 arranged side by side in parallel along the length direction. Several reinforcing ribs 11 are welded to the top surface of the work platform 1. The reinforcing ribs 11 are arranged in parallel with each other and their direction is perpendicular to the length direction of the rectangular grooves 12.
[0026] Combination Figure 2 and Figure 3 The ladder frame includes two legs arranged at the front and rear. A connecting plate is fixed to the upper end of the ladder frame, and the front and rear ends of the connecting plate are respectively fixed to the corresponding legs. The connecting plate is provided with a bushing, which is sleeved on a rotating shaft fixed to the corresponding side of the bottom of the work platform to form a rotating pair. Figure 1 , Figure 2 The ladder frame on the left is the first ladder frame 3, and the ladder frame on the right is the second ladder frame 4. The first ladder frame 3 is rotatably connected to the first rotating shaft 7 fixed on the bottom left side of the work platform 1 via a bushing fixed on the first connecting plate 31 at its top. The second ladder frame 4 is rotatably connected to the second rotating shaft 8 fixed on the bottom right side of the work platform 1 via a bushing fixed on the second connecting plate 43 at its top. The legs of the second ladder frame 4 are fixed support columns 41, which are round steel pipes. The side wall of the fixed support column 41 has a strip groove arranged along the axial direction of the fixed support column 41. The strip groove has multiple buckles 411 that are perpendicular to the strip groove and communicate with it along its length. A telescopic rod 42 extending from the lower end of the fixed support column 41 is slidably arranged inside the fixed support column 41. The telescopic rod 42 is connected to a fixing pin 421 for cooperating with the buckles 411 to fix the extension length of the telescopic rod 42.
[0027] Optionally, the locking groove 411 cooperates with the fixing pin 421 to adjust the length of the second ladder 4 to compensate for the slope difference, achieving equal angle differences of 0°, 4°, 8°, 12°, and 16° between the working platform 1 and the ramp plane, so that the working platform 1 remains basically horizontal, improving the safety of working at height on ramps or uneven ground. During processing, the dimensions of the required components are calculated in advance based on the adjustment angle, and the components are processed and assembled in the processing workshop.
[0028] Optionally, the buckle grooves 411 are arranged at equal intervals.
[0029] A footboard is fixed between the two legs on the same side, and the spacing between the footboards meets the step height requirement. As an optional embodiment of this invention, the second ladder frame 4 has a greater number of footboards than the first ladder frame 3. Optionally, the first ladder frame 3 has two footboards, and the second ladder frame 4 has three footboards.
[0030] Optionally, the legs and steps of the first ladder frame 3 are made of angle steel.
[0031] The working platform 1 is hinged to the first ladder 3 and the second ladder 4, respectively, with diagonal braces 2. Specifically, the upper end of the diagonal brace 2 is rotatably connected to the side of the working platform 1 via a pin 5, and the lower end of the diagonal brace 2 is rotatably connected to a support leg, which is connected to a locking member 6. Optionally, the diagonal brace 2 is made of flat steel.
[0032] like Figure 4 As shown, the locking component 6 includes a fastening pin 61 whose inner end is fixed to the support leg. The outer end of the fastening pin 61 has a slotted opening, through which a long strip-shaped locking piece 62 is connected. The locking piece 62 has a slotted hole, and the locking piece 62 is rotatably connected to the fastening pin 61 by a short pin that passes through the slotted hole and is fixed between the inner walls on both sides of the slotted opening. The bottom of the diagonal brace 2 has a through hole for the locking component 6 to pass through, and the bottom surface of the slotted opening is inside the through hole. One end of the locking piece 62 is an arc-shaped locking head. If the rotation radius of the locking head is R and the length of the short side of the locking piece is D, then R must be greater than D / 2. When the locking piece 62 rotates until its long side is parallel to the axial direction of the through hole on the diagonal brace 2, the slotted hole of the locking piece 62 allows its body to move closer to the short pin along its length direction, and the arc-shaped outer edge of its locking head can be engaged in the through hole of the diagonal brace 2, thereby achieving locking. To unlock, rotate the locking plate 62 to disengage its locking head from the through hole, and continue rotating it by about 90° until its long side is parallel to the long axis of the diagonal brace 2.
[0033] When using this utility model of downhole drilling platform, first, position the platform along the slope of the roadway, with the first ladder 3 facing the top of the slope and the second ladder 4 facing the bottom. Then, extend the first ladder 3 and the second ladder 4 to their maximum extension angle. Next, rotate the telescopic rod 42 clockwise to allow the fixing pin 421 to enter the slot. Then, slide the telescopic rod 42 up and down along the slot to adjust its extension length, ensuring the working platform 1 is level. Finally, engage the fixing pin 421 of the telescopic rod 42 with the corresponding height of the locking slot 411. Lock the locking member 6 to secure the diagonal brace 2 to the corresponding ladder leg, forming a stable triangle with the working platform 1, the legs, and the diagonal brace 2, ensuring the stability of the entire drilling platform. After drilling is completed or when encountering narrow roadways that hinder transportation, release the locking of the diagonal brace 2 to the ladder and retract the telescopic rod 42 to fold and retract the entire frame.
[0034] It should be noted that, as will be apparent to those skilled in the art, this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. The scope of this utility model is defined by the claims rather than the foregoing description.
