A mud tank protection mechanism

Abstract

This utility model discloses a mud tank protection mechanism, specifically relating to the field of mud tank guardrails. It includes a front guardrail, a right guardrail, a rear guardrail, a left guardrail, and a fixing block. The fixing block can be installed on the top surface of the tank. The front, right, rear, and left guardrails are arranged sequentially end-to-end and connected to the corresponding fixing blocks via rotating rods to allow each guardrail to flip towards the top of the tank. Simultaneously, the bottom of each of the front, right, rear, and left guardrails is equipped with a kick plate. By sequentially adjusting the height of the guardrails, releasing the locking mechanism, and then rotating the front and rear guardrails inwards to place them on the top surface of the tank, followed by flipping the left and right guardrails inwards so that they horizontally press against the top surfaces of the front and rear guardrails, this not only achieves a storage effect but also allows the kick plates to be stored along with the guardrails, preventing deformation and damage to the kick plates caused by the steel wire rope squeezing them during hoisting.

Description

Technical Field

[0001] This utility model relates to the field of mud tank guardrail technology, specifically a mud tank protection mechanism. Background Technology

[0002] Drilling mud tanks are key equipment used in oil drilling, geological exploration, and mining operations for storing, circulating, and processing drilling mud (drilling fluid). Drilling mud is a fluid composed of water, clay, chemical additives, and other components, and plays a crucial role in drilling operations by cooling the drill bit, carrying cuttings, balancing formation pressure, and protecting the wellbore.

[0003] The top of the mud tank is the main operating area for workers (such as inspection, sampling, and equipment maintenance). The guardrails prevent accidental falls by personnel through physical barriers (especially at the edges or openings of the tank), reducing the risk of falls from heights. At the same time, the guardrails can limit the range of personnel's activities and prevent accidental contact with rotating parts inside the tank (such as agitators) or approach to dangerous areas.

[0004] Chinese patent publication CN213645043U discloses a novel folding protective railing for a mud tank, filed on August 6, 2020. This patented technology solves the problems of fixed protective railings being too high to disassemble and plug-in protective railings being easily lost and difficult to operate. The railing also includes a kick guard plate at the bottom to prevent workers or objects from accidentally slipping. However, in the aforementioned device, the kick guard plate is located at the top edge of the mud tank. During hoisting of the mud tank, the crane's wire rope comes into contact with the kick guard plates at all four locations on the top of the mud tank. When the crane lifts the mud tank, the wire rope squeezes the kick guard plate, causing it to dent and deform. Therefore, the inventors provide a mud tank protection mechanism to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a mud tank protection mechanism that allows the kick plate to be stored together with the guardrail, preventing the wire rope from squeezing the kick plate during hoisting.

[0008] As a further embodiment of this utility model: at least one set of horizontally arranged dividing bars are fixedly connected inside the bottom frame of the guardrail, which divides the bottom frame of the guardrail into multiple independent spaces, and the kick plate includes multiple sets, which are fixed in the corresponding spaces respectively.

[0009] As a further embodiment of this utility model: rotating rods are fixedly connected to both sides of the front guardrail, right guardrail, rear guardrail, and left guardrail near the adjacent fixed blocks, and the rotating rods on the left and right guardrails are positioned higher than the rotating rods on the front and rear guardrails.

[0010] As a further improvement of this utility model: the rotating rod is rotatably connected to the surface of the corresponding fixed block, and the fixed block is provided with a positioning mechanism for fixing the angle of the guardrail.

[0011] As a further embodiment of this utility model: the positioning mechanism includes a vertical groove formed inside the fixed block, a sliding groove first formed on one side of the vertical groove, a guide rail first fixedly connected to the bottom inner side of the sliding groove first, a positioning block first that can move left and right slidably connected to the top of the guide rail first, positioning slots first formed on the left and right sides of the front guardrail and the rear guardrail respectively, and positioning blocks first inserted into the corresponding positioning slots first; a sliding groove second formed on one side of the vertical groove, a guide rail second fixedly connected to the bottom inner side of the sliding groove second, a positioning block second that can move back and forth slidably connected to the top of the guide rail second, positioning slots second formed on the front and rear sides of the left guardrail and the right guardrail respectively, and positioning blocks second inserted into the corresponding positioning slots second; and the position of positioning block second is higher than that of positioning block first.

[0012] As a further embodiment of this utility model: the top of the fixing block is threaded with a stud, the bottom of the stud is connected to a sliding block via a bearing, the inner ring of the bearing is fixedly connected to the stud, and the outer ring of the bearing is fixedly connected to the sliding block; the side of the sliding block near the first positioning block is hinged to the first positioning block via a connecting rod, and the side of the sliding block near the second positioning block is hinged to the second positioning block via a connecting rod; a guide rod is fixedly connected to the bottom inner side of the vertical groove, and the guide rod is slidably connected to the sliding block.

[0013] As a further embodiment of this utility model: the guardrail includes an upper horizontal bar, and a set of telescopic rods corresponding one-to-one with the hollow tubes are fixedly connected to the bottom of the horizontal bar. A pair of positioning holes arranged vertically are opened on the outer side of the left and right telescopic rods. The telescopic rods are slidably connected to the corresponding hollow tubes. The tops of the left and right hollow tubes are respectively fixedly connected to connecting frames. Bolts are threadedly connected to the outer side of the connecting frames. The bolts are inserted into the positioning holes of the corresponding telescopic rods.

[0014] As a further embodiment of this utility model: there is a gap between the left guardrail and the rear guardrail, and a side block is provided on the rear side of the left guardrail. The side block is fixedly connected to the top of the mud tank, and the side block is rotatably connected to the rotating rod on the rear side of the left guardrail.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This mud tank protection mechanism works by sequentially adjusting the height of the guardrails, then releasing the locking mechanism on the guardrails, and then rotating the front and rear guardrails inward to place them on the surface of the tank. Next, the left and right guardrails are flipped inward, so that they are horizontally pressed against the top surfaces of the front and rear guardrails, thus achieving a storage effect. This also allows the kickboard to be stored along with the guardrails, preventing damage to the kickboard from the steel wire rope squeezing it during hoisting.

[0016] In addition, the mud tank protection mechanism works by first flipping the two corresponding guardrails upwards to a vertical position, then rotating the studs downwards. The downward rotation of the studs drives the sliding block to slide down the guide rod through the bearing. As the sliding block slides down, it drives the positioning block one and positioning block two to slide outwards through the connecting rods on both sides until positioning block one is inserted into positioning groove one and positioning block two is inserted into positioning groove two. The above operation is performed on the four studs in sequence to achieve the effect of fixing the entire guardrail body in the use state. Attached Figure Description

[0019] Example 1 The device includes a front guardrail 12, a right guardrail 14, a rear guardrail 15, a left guardrail 16, and a fixing block 10. The left guardrail 16 and the right guardrail 14 are guardrails set in the width direction of the tank top, while the front guardrail 12 and the rear guardrail 15 are guardrails set in the length direction of the tank top. The fixing block 10 can be installed on the surface of the tank top, specifically determined according to the tank size. In this embodiment, the tank width is 3m and the length is 10m. When the size of each guardrail corresponds to the tank size, the fixing block 10 can be set at the four corner positions of the tank top surface. When the size of each guardrail is smaller than the tank size, the fixing block 10 is set at the required position on the tank top.

[0020] The front guardrail 12, right guardrail 14, rear guardrail 15, and left guardrail 16 are arranged sequentially and connected to the corresponding fixing blocks 10 via rotating rods 17 to allow each guardrail to flip towards the top of the tank. The left guardrail 16 and right guardrail 14, as well as the front guardrail 12 and rear guardrail 15, have the same structure, forming a frame that is connected end to end. At the same time, the bottom of the front guardrail 12, right guardrail 14, rear guardrail 15, and left guardrail 16 are all equipped with kick guards 203. These kick guards 203 can be flipped into the tank synchronously with the corresponding guardrails to fold and prevent the wire rope from squeezing the kick guards and causing them to deform and be damaged during hoisting. In later operations, one side of the guardrail can be folded to allow workers to enter.

[0021] In practical use, the front guardrail 12 and the rear guardrail 15 are rotated inward and placed on the surface of the tank. Then, the left guardrail 17 and the right guardrail 14 are flipped inward so that the left guardrail 17 and the right guardrail 14 are horizontally pressed on the top surface of the front guardrail 12 and the rear guardrail 15. This achieves both the effect of guardrail storage and the purpose of storing the kick plate along with the guardrail, preventing the wire rope from squeezing the kick plate and causing it to be damaged during hoisting.

[0022] Example 2 like Figures 1-4As shown, this embodiment provides a mud tank protection mechanism, including a front guardrail 12, a right guardrail 14, a rear guardrail 15, and a left guardrail 16. Fixed blocks 10 are respectively installed at adjacent corners of the guardrails, and the fixed blocks 10 are fixedly connected to the top of the mud tank. There is a gap between the left guardrail 16 and the rear guardrail 15, which allows workers to enter the protection mechanism for subsequent operations after it is erected. A side block 11 is provided on the rear side of the left guardrail 16, and the side block 11 is fixedly connected to the top of the mud tank. Rotating rods 17 are fixedly connected to the sides of the front guardrail 12, right guardrail 14, rear guardrail 15, and left guardrail 16 near the adjacent fixed blocks 10, with the left and right rotating rods 17 positioned higher than the front and rear rotating rods 17. The rotating rods 17 are rotatably connected to the corresponding fixed blocks 10, and the rotating rod 17 on the rear side of the left guardrail 16 is rotatably connected to the side block 11. A positioning mechanism 30 for fixing the guardrail angle is provided inside the fixed block 10.

[0023] refer to Figures 1-4 The front guardrail 12, right guardrail 14, rear guardrail 15, and left guardrail 16 have the same structure, each including a guardrail base frame 201 fixedly connected to the corresponding rotating rod 17. A set of horizontally arranged dividing rods 202 are fixedly connected inside the guardrail base frame 201. The dividing rods 202 divide the interior of the guardrail base frame 201 into multiple independent spaces. A kick guard plate 203 is fixedly connected inside the space. A set of horizontally arranged hollow tubes 204 are fixedly connected to the top of the guardrail base frame 201. A guardrail bar 205 is set on the top of the set of hollow tubes 204.

[0024] Preferably, the guardrail 205 includes a horizontal bar at the highest point, and a set of telescopic rods corresponding one-to-one with the hollow tubes 204 are fixedly connected to the bottom of the horizontal bar. The outermost two telescopic rods have a pair of positioning holes arranged vertically on their outer sides, and the telescopic rods are slidably connected to the corresponding hollow tubes 204. The tops of the two outermost hollow tubes 204 are respectively fixedly connected to a connecting frame 206, and the outer side of the connecting frame 206 is threaded with a bolt, which is inserted into the positioning hole of the corresponding telescopic rod.

[0025] When a set of side blocks 11 needs to be stored, first adjust the height of the guardrail in the order of front, back, left, and right. During adjustment, loosen the bolts on the corresponding sides of the guardrail to disengage the bolts from the lower positioning holes. Then press the guardrail bar 205 downwards to allow a set of telescopic rods to slide downwards along the inside of the hollow tube 204, lowering the overall height of the guardrail until the upper positioning hole aligns with the position of the connecting frame 206. Then thread the bolts to the connecting frame 206 and insert them into the upper positioning holes to fix the guardrail height after adjustment. First, rotate the front guardrail 12 and rear guardrail 15 inwards and place them on the ground. Then, flip the left guardrail 16 and right guardrail 14 inwards so that the left guardrail 16 and right guardrail 14 are horizontally pressed onto the top surface of the front guardrail 12 and rear guardrail 15 (e.g., Figure 3 The guardrail is laid flat on top of the mud tank and the edges are smooth, so as not to interfere with the hoisting of the mud tank.

[0026] refer to Figure 1 , Figure 5 , Figure 6 The positioning mechanism 30 includes a vertical groove 308 formed inside the fixed block 10. A sliding groove 302 is formed on the side of the vertical groove 308 near the horizontal guardrail. A guide rail 304 is fixedly connected to the bottom inner side of the sliding groove 302. A positioning block 303, which can move left and right, is slidably connected to the top of the guide rail 304. Positioning grooves 301 are formed on the left and right sides of the front guardrail 12 and the rear guardrail 15, respectively. The positioning block 303 corresponds to the positioning groove 301. 1. Insertion; A sliding groove 305 is provided on the side of the vertical groove 308 near the longitudinal guardrail. A guide rail 307 is fixedly connected to the bottom inner side of the sliding groove 305. A positioning block 306 that can move back and forth is slidably connected to the top of the guide rail 307. Positioning grooves 314 are respectively provided on the front and rear sides of the left guardrail 16 and the right guardrail 14. The positioning block 306 is inserted into the corresponding positioning groove 314. The position of the positioning block 306 is higher than that of the positioning block 303.

[0027] Specifically, the top of the fixing block 10 is threaded with a stud 311, and the bottom of the stud 311 is connected to a sliding block 310 via a bearing 312. The inner ring of the bearing 312 is fixedly connected to the stud 311, and the outer ring of the bearing 312 is fixedly connected to the sliding block 310. The side of the sliding block 310 near the first positioning block 303 is hinged to the first positioning block 303 via a connecting rod 313, and the side of the sliding block 310 near the second positioning block 306 is hinged to the second positioning block 306 via a connecting rod 313.

[0028] Preferably, a guide rod 309 is fixedly connected to the bottom inner side of the vertical groove 308, and the guide rod 309 is slidably connected to the sliding block 310; thereby achieving the effect of guiding the sliding block 310 when it moves.

[0029] When positioning and fixing the guardrail during use, first flip the two corresponding guardrails upwards to a vertical position, then rotate the stud 311 downwards. The downward rotation of the stud 311 drives the sliding block 310 to slide downwards along the guide rod 309 through the bearing 312. When the sliding block 310 slides down, it drives the positioning block 1 303 and positioning block 2 306 to slide outwards through the connecting rods 313 on both sides, until positioning block 1 303 is inserted into positioning groove 1 301 and positioning block 2 306 is inserted into positioning groove 2 314. The above operation is performed on the four studs 311 in sequence to fix the entire guardrail body in the use state. At the same time, when the guardrail is in the storage state, the four studs 311 are moved down in sequence, which can extend the positioning block 1 303 and positioning block 2 306 outwards to abut against the surface of the corresponding guardrail, thereby fixing the position of the guardrail in the storage state.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
