Description

Technical Field

[0001] This utility model belongs to the field of drilling technology, specifically a tank farm centrifuge solids control unit for drilling operations. Background Technology

[0002] The solids control unit of the centrifuge in the tank area usually includes a centrifuge frame and a control room, which is used to observe the operating status of the centrifuge during the grouting process. By setting up remote monitoring equipment in the control room, parameters such as centrifuge speed and vibration value can be observed and displayed in real time on the touch screen in the control room. In case of abnormality (such as vibration exceeding the threshold), the machine will automatically stop and alarm.

[0003] Currently, after the completion of construction in the work area, the centrifuge support, control room, and rain shelter can be transferred through standardized hoisting procedures. However, due to the large size and weight of the control room, a crane is required for separate handling during transfer. Using a separate transfer method requires the independent disassembly of the centrifuge support, rain shelter, and control room, significantly increasing the occupancy rate of the transport space. Furthermore, each component needs to be transferred separately, and subsequent installation requires not only reassembly of the components but also equipment calibration and system debugging, making the entire process complex and time-consuming. In addition, frequent disassembly and assembly operations not only increase labor costs but may also affect the structural stability and sealing performance of the equipment due to repeated disassembly, thereby reducing the overall system reliability. Therefore, the inventors have provided a novel structure for a tank farm centrifuge solids control unit for drilling operations to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a solids control unit for a tank farm centrifuge used in drilling operations, which achieves the effect of integrated hoisting and transportation of the work station, centrifuge frame, and rainproof canopy.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A solids control unit for a tank farm centrifuge used in drilling operations includes a centrifuge frame, a base plate, and fixed sleeves fixedly connected to the top corners of the base plate. A fixed frame is fixedly connected to the outer sides of a set of fixed sleeves. A rain shelter is provided on the top of the centrifuge frame, and the rain shelter includes a sliding rod slidably connected to the inside of the set of fixed sleeves. A canopy is fixedly connected to the top of the set of sliding rods. A flipping support mechanism is provided inside the fixed frame, and a guardhouse body is supported on the top of the flipping support mechanism. A hoisting connection mechanism is provided on the top of the guardhouse body, and the hoisting connection mechanism includes a fixed box fixedly connected to the top of the guardhouse body. The fixed box is hollow inside, and rotatable bidirectional threaded rods are rotatably connected to its front and rear sides. A pair of movable blocks arranged left and right are threadedly connected to the outer sides of the bidirectional threaded rods. Connecting blocks are fixedly connected to the left and right sides of the movable blocks, and lifting rods are fixedly connected to the outer sides of the connecting blocks.

[0007] As a further embodiment of this utility model: the top of the fixing box is provided with a groove, the top of the fixing box is fixedly connected to a motor, the output end of the motor and the outer side of the bidirectional threaded rod are respectively fixedly connected to synchronous pulleys, and the outer sides of the two synchronous pulleys are engaged with a transmission belt; a pair of guide rings arranged left and right are fixedly connected to the front and rear sides of the top of the guardhouse body, and the guide rings are slidably connected to the corresponding hanging rods.

[0008] As a further improvement of this utility model: a set of positioning holes are provided on the front of the slide rod, and a movable pin is provided on the top of the front of the fixed sleeve rod.

[0009] As a further improvement of this utility model: a pair of arc-shaped grooves are respectively provided on the front and rear sides of the fixed frame, and an arc-shaped piece is provided on the top of the arc-shaped groove. The arc-shaped piece is fixed to the outside of the arc-shaped groove by bolts.

[0010] As a further embodiment of this utility model: the flipping support mechanism includes a pair of flipping support plates arranged on the left and right sides, and rotating rods are fixedly connected to the front and rear sides of the flipping support plates respectively. The outer sides of the rotating rods are rotatably connected to the fixed frame respectively. A flipping groove is opened on the front side of the flipping support plate. The pair of rotating rods on the front side penetrate the surface of the fixed frame and are located in the flipping groove. Gears are fixedly connected to the outer sides of the rotating rods on the front side. A bidirectional cylinder is fixedly connected inside the flipping groove. Gear plates are fixedly connected to the left and right output ends of the bidirectional cylinder respectively. The gear plates mesh with the corresponding side gears respectively.

[0011] As a further embodiment of this utility model: sockets are fixedly connected to the front and rear sides of the top of the flip support plate, and a plug rod is slidably connected inside the socket; a pair of lock seats arranged left and right are fixedly connected to the front and rear sides of the fixed frame, and the plug rod is inserted into the corresponding lock seat; a positioning seat is fixedly connected to the top of the flip support plate, and positioning blocks are fixedly connected to the bottom of the left and right sides of the guardhouse body, and the positioning blocks are inserted into the corresponding positioning seats.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The solids control unit for the tank farm centrifuge in drilling operations is assembled by opening the hoisting connection mechanism, extending the boom outward, connecting the crane hoisting components to the boom, moving the boom and the work station upward, closing the tilting support mechanism, lowering the work station into the centrifuge frame, connecting the boom to the centrifuge frame via an arc-shaped plate, and finally releasing the cover to lower the cover, completing the storage of the entire unit. The three components (centrifuge support, work station, and rain shelter) can be simultaneously transported by crane, achieving the effect of integrated hoisting and transport of the work station, centrifuge frame, and rain shelter.

[0014] In addition, when closing the tilting support mechanism of the centrifuge solids control unit used in the drilling operation, the crane first lifts the main body of the work station to separate the positioning block from the positioning seat. Then, the operator separates a set of rods from the lock seat. Finally, the bidirectional cylinder is started by the external power supply. The output end of the bidirectional cylinder retracts, driving the two toothed plates to move towards each other. Through the transmission of the toothed plates and gears, the tilting support plates on both sides are tilted downwards to a vertical position, completing the closing of the tilting support mechanism and achieving the effect of switching the tilting support mechanism's form, which facilitates the transfer of subsequent equipment.

[0021] like Figures 1-4 As shown, the solids control unit of the tank farm centrifuge for drilling operations includes a centrifuge frame 10. The centrifuge frame 10 includes a base plate 101. Fixed sleeve rods 102 are fixedly connected to the top corners of the base plate 101. A fixed frame 103 is fixedly connected to the outer side of a group of fixed sleeve rods 102. A rain shelter 11 is provided on the top of the centrifuge frame 10. The rain shelter 11 includes sliding rods 111 that are slidably connected to the inside of a group of fixed sleeve rods 102. A cover 110 is fixedly connected to the top of a group of sliding rods 111. A flipping support mechanism 2 is provided inside the fixed frame 103. 0. The top of the flipping support mechanism 20 supports the guardhouse body 12. The top of the guardhouse body 12 is provided with a hoisting connection mechanism 30. The hoisting connection mechanism 30 includes a fixed box 301 fixedly connected to the top of the guardhouse body 12. The fixed box 301 is hollow inside and has a rotatable bidirectional threaded rod 302 rotatably connected to both the front and rear sides inside. The outer side of the bidirectional threaded rod 302 is threadedly connected to a pair of moving blocks 303 arranged left and right. The left and right sides of the moving blocks 303 are respectively fixedly connected to connecting blocks 304. The outer side of the connecting blocks 304 is fixedly connected to a hanging rod 305.

[0022] Specifically, the top of the fixed box 301 has a groove, and a motor 308 is fixedly connected to the top of the fixed box 301. The output end of the motor 308 and the outer side of the bidirectional threaded rod 302 are respectively fixedly connected to synchronous pulleys 310, and the outer sides of the two synchronous pulleys 310 are engaged with a transmission belt 309. A pair of guide collars 307 arranged on the left and right are fixedly connected to the front and rear sides of the top of the guardhouse body 12, and the guide collars 307 are slidably connected to the corresponding hanging rods 305.

[0023] Preferably, the sliding rod 111 has a set of positioning holes 112 on its front side, and the fixed sleeve rod 102 has a movable pin on its top front side. In use, the height of the rain shelter 11 is locked by inserting the movable pin into one of the positioning holes 112.

[0024] Preferably, a pair of arc-shaped grooves 104 are provided on the front and rear sides of the fixed frame 103, and an arc-shaped piece 105 is provided on the top of the arc-shaped groove 104. The arc-shaped piece 105 is fixed to the outside of the arc-shaped groove 104 by bolts.

[0025] After the construction of the work area is completed, the centrifuge bracket, the guardhouse, and the rain shelter 11 can be transported through a standardized hoisting operation procedure. During the transport, the guardhouse is large in size and weight, so a crane is required for handling. If they are transported separately, the centrifuge bracket 10, the rain shelter 11, and the guardhouse body 12 need to be disassembled first. As a result, these three items take up a lot of space during transport, and it is inconvenient to install them after transport. Moreover, it is troublesome to transport them one by one. In this device, the above three items can be transported at the same time, without taking up space, and are easy to install after transport.

[0026] During rotation, first activate the hoisting connection mechanism 30. In use, start the motor 308 via an external power source. The output of the motor 308 rotates, driving the synchronous pulley 310 to rotate. Through the synchronous pulley 310 and the transmission belt 309, the bidirectional threaded rod 302 rotates, causing the two moving blocks 303 to move in opposite directions. This, in turn, drives the boom 305 outwards via the connecting block 304, so that the outer connecting end of the boom 305 exceeds the width of the rain shelter 11. Then, connect the crane hooks to the ends of the booms 305 on both sides, and use the crane to lift the booms 305 and the guardhouse body. 12 is lifted upwards, but not exceeding the top of the rain shelter 11. Then, the flip support mechanism 20 is closed, exposing the top of the centrifuge frame 10. The crane then lowers the guardhouse body 12 to contact the bottom inner side of the centrifuge frame 10, placing the guardhouse body 12 inside the centrifuge frame. Simultaneously, the bottom of the lifting rod 305 is moved into the arc-shaped groove 104. The arc-shaped piece 105 is then fixed to cover the lifting rod 305 above the arc-shaped groove 104, and the lifting rod 305 is fixed inside the arc-shaped groove 104, completing the rigid connection between the lifting rod 305 and the centrifuge frame 10. Finally, the movable pins on all four sides are unlocked, allowing the slide rod 111 to slide to the deepest part inside the fixed sleeve rod 102, causing the canopy 110 to slide down (as shown). Figure 2 (Then, when the hoisting boom 305 is lifted by the crane, the centrifuge frame 10, the guardhouse body 12, and the rainproof canopy 11 can be hoisted and transported. The storage space of the three is reduced through the above steps, which facilitates transportation. At the same time, the three can be restored by the reverse method, which achieves the effect of convenient installation and storage operation.

[0027] refer to Figure 1 , Figure 5 The flipping support mechanism 20 includes a pair of flipping support plates 202 arranged on the left and right. Rotating rods 203 are fixedly connected to the front and rear sides of the flipping support plates 202 respectively. The outer sides of the rotating rods 203 are rotatably connected to the fixed frame 103 respectively. A flipping groove 201 is opened on the front side of the flipping support plate 202. The pair of rotating rods 203 on the front side penetrate the surface of the fixed frame 103 and are located in the flipping groove 201. Gears 204 are fixedly connected to the outer sides of the rotating rods 203 on the front side. A two-way cylinder 206 is fixedly connected inside the flipping groove 201. Gear plates 205 are fixedly connected to the left and right output ends of the two-way cylinder 206 respectively. The gear plates 205 mesh with the corresponding side gears 204 respectively.

[0028] Furthermore, sockets 207 are fixedly connected to the front and rear sides of the top of the flip support plate 202, and a plug rod 208 is slidably connected inside the socket 207. A pair of lock seats 209 arranged left and right are fixedly connected to the front and rear sides of the fixed frame 103, and the plug rod 208 is inserted into the corresponding lock seat 209. A positioning seat 210 is fixedly connected to the top of the flip support plate 202, and positioning blocks 121 are fixedly connected to the bottom of the left and right sides of the guardhouse body 12, and the positioning blocks 121 are inserted into the corresponding positioning seats 210.

[0029] During use, the two horizontally positioned tilting support plates 202 distribute the weight of the guardhouse body 12 by inserting a set of rods 208 into the lock seat 209, preventing rapid wear at the connection between the gear 204 and the toothed plate 205. Simultaneously, the positioning block 121 connects to the positioning seat 210, preventing the guardhouse body 12 from swaying on the tilting support plates 202. When closing the tilting support mechanism 20, the crane first lifts the guardhouse body 12 to separate the positioning block 121 from the positioning seat 210. Then, the operator separates the set of rods 208 from the lock seat 209. Finally, the bidirectional cylinder 206 is activated via an external power supply. The output end of the bidirectional cylinder 206 retracts, causing the two toothed plates 205 to move towards each other. Through the transmission between the toothed plates 205 and the gear 204, the two tilting support plates 202 are tilted downwards to a vertical position, completing the closure of the tilting support mechanism 20.

[0030] The working principle of this utility model is as follows: First, the hoisting connection mechanism 30 is activated. During use, the motor 308 is started by an external power supply. The output end of the motor 308 rotates, driving the synchronous pulley 310 to rotate. Through the transmission of the synchronous pulley 310 and the transmission belt 309, the bidirectional threaded rod 302 rotates, thereby driving the two moving blocks 303 to move in opposite directions. This, in turn, drives the lifting rod 305 to move outward through the connecting block 304, so that the connecting end of the outer side of the lifting rod 305 exceeds the width of the rainproof canopy 11. Then, the hooks of the crane are connected to the ends of the lifting rods 305 on both sides respectively, and the lifting rods 305 and the seat are lifted by the crane. The main body 12 of the shelter is hoisted upwards, but not exceeding the top of the rain shelter 11. Then, the flip support mechanism 20 is closed, exposing the top of the centrifuge frame 10. The crane then lowers the main body 12 of the shelter to contact the bottom inner side of the centrifuge frame 10, placing the main body 12 of the shelter inside the centrifuge frame. Simultaneously, the bottom of the lifting rod 305 is moved into the arc-shaped groove 104. The arc-shaped piece 105 is then fixed to cover the lifting rod 305 above the arc-shaped groove 104 with bolts, and the lifting rod 305 is fixed inside the arc-shaped groove 104, completing the rigid connection between the lifting rod 305 and the centrifuge frame 10. Finally, the movable pins on all four sides are unlocked, allowing the sliding rod 111 to slide to the deepest part inside the fixed sleeve 102, causing the canopy 110 to slide down (as shown). Figure 2 (Then, when the hoisting boom 305 is lifted by the crane, the centrifuge frame 10, the guardhouse body 12, and the rainproof canopy 11 can be hoisted and transported. The storage space of the three is reduced through the above steps, which facilitates transportation. At the same time, the three can be restored by the reverse method, which achieves the effect of convenient installation and storage operation.

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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
