Description

Technical Field

[0001] The utility model belongs to the technical field of drilling site mud tanks, in particular to a foldable push-pull type protective shed for a drilling mud tank area. Background Art

[0002] In oil and gas drilling operations, mud tanks are core equipment in the mud circulation system, used to store, mix, and circulate drilling fluid. Because drilling sites are often located in harsh environments such as deserts, Gobi Desert, and offshore, mud tanks are susceptible to strong winds, dust storms, rain, and snow, leading to mud contamination, equipment wear, and reduced operational efficiency. Therefore, existing technologies typically employ wind and sand-proof sheds to protect these tanks.

[0003] The current tank protective sheds are installed on the top of a single tank and are divided into mechanical and electric types. When the mud tank is moved, the shed on each tank needs to be lowered before it can be loaded onto a truck for transportation. Its shortcomings are: this type of protective shed is only suitable for a single tank. For example, when there are 70 drilling rigs on site, 7 sheds need to be made, which increases the design and manufacturing cost of the shed. In addition, this type of protective shed is folded by lifting, and multiple lifting operations are required during moving or installation, which greatly reduces the efficiency of moving and installation.

[0004] Based on the above analysis, the applicant has designed a foldable push-pull protective shed for the drilling mud tank area through experiments. Utility Model Content

[0009] The shed body further comprises a fixed support frame, the fixed support frame comprising a first fixing frame and a second fixing frame, the first fixing frame being fixed to the end of the track unit, the second fixing frame being connected end to end to the folding support frame, the second fixing frame being located at the beginning of the track unit and being capable of being hoisted and transported synchronously with the folding support frame;

[0010] The tops of the folding support frame and the second fixing frame are both provided with arc-shaped keels, wherein the arc-shaped keels located on the top of the folding support frame can be synchronously expanded or retracted with the lateral folding frame.

[0011] As a preferred solution of the present application: the lateral folding frame is provided with an automatic pushing and pulling unit, which includes a pulley group and an electric winch. The pulley group includes multiple pulleys, which are respectively fixed on the first fixed frame and the second fixed frame. The rope of the electric winch is connected to the lateral folding frame and is wound around the pulley group to perform tension reversal, thereby realizing the expansion or folding movement of the lateral folding frame.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below in conjunction with specific implementation methods and with reference to the accompanying drawings. It should be emphasized that the following description is merely illustrative and is not intended to limit the scope of the present invention and its applications.

[0026] This embodiment provides a foldable push-pull type protective shed for drilling mud tank area, such as Figure 1-3As shown, it includes a guide bracket 10 and a shed body 20, which are independent and mutually coordinated structures, wherein the guide bracket 10 can be installed on the top surface of the tank body 30, and includes a track unit 101 arranged in parallel along the length direction of the tank body 30 and a bracket 102 arranged at the bottom of the track unit 101, the track unit 101 has a limiting guiding function, preferably a trough structure, specifically composed of channel steel, and the effective stroke of the track unit 101 is 10600-12000mm; the bracket 102 is used to support the track unit 101 on the one hand, and to connect with the top surface of the tank body 30 on the other hand. It can be understood that in order to facilitate disassembly and assembly and transportation, preferably the bracket 102 is fixed to the top surface of the tank body 30 by a detachable connector such as a bolt or a pin; in this embodiment, the guide bracket 10 preferably includes two groups, which are respectively installed on both sides of the width direction of the tank body 30; the shed body 20 at least includes a folding support frame 201, the folding support frame 201 includes a lateral folding frame 2011 and a protective tarpaulin 40, the lateral folding frame 2011 includes two groups corresponding to the number of the guide brackets 10, and the two groups of lateral folding frames 2011 are relatively arranged to form a rectangular frame. In addition, it can be understood that in order to improve the stability of the rectangular frame, a keel should be provided at the upper end of the two groups of lateral folding frames 2011. In this embodiment, Preferably, the arc-shaped keel 207 can be expanded or retracted synchronously with the lateral folding frame 2011. The use of the arc-shaped keel 207 can avoid the accumulation of rainwater or snow on the top; a guide wheel group 2012 is provided at the bottom of the lateral folding frame 2011, and the guide wheel group 2012 forms a rolling pair with the track unit 101 to realize the expansion or retraction movement of the lateral folding frame 2011 along the axial direction of the track unit 101. It can be understood that the expansion or retraction of the lateral folding frame 2011 can be electrically controlled or manually pushed and pulled; the protective tarpaulin 40 covers the top of the lateral folding frame 2011 and / or the surface of the lateral folding frame 2011 Surface, forming a continuous protection surface, that is, according to needs, the protective tarpaulin 40 can only cover the top or surface of the side folding frame 2011, or can cover the top and surface of the side folding frame 2011 at the same time. Specifically, in this embodiment, when the temperature is high, for example, above 5°C, the protective tarpaulin 40 is only arranged above the side folding frame 2011, that is, on the arc keel 207, to provide sunshade and rain protection. When the temperature is low, for example, below 5°C, and the environment is relatively harsh, the protective tarpaulin 40 is simultaneously arranged above the side folding frame 2011 and on the surface of the side folding frame 2011 to provide multiple protections such as heat preservation, windproof, sandproof, rain and snowproof.

[0027] As a preferred solution of this embodiment, the shed body 20 further includes a fixed support frame, which includes a first fixing frame 202 and a second fixing frame 203. The first fixing frame 202 is fixed to the end of the track unit 101. The first fixing frame 202 is a rod structure and is preferably fixed to the top surface of the tank body 30 by welding. It can be understood that the first fixing frame 202 should include two rods, which are respectively fixed to the ends of the two groups of track units 101; the second fixing frame 203 is connected end to end with the folding support frame 201 (the connection here is preferably connected by welding to connect the rear end of the second fixing frame 203 to the front end of the folding support frame 201). The second fixing frame 203 is located at the starting end of the track unit 101 and can be hoisted and transported synchronously with the folding support frame 201. In this embodiment, the second fixing frame 203 includes a top arc-shaped keel 207 and a side fixing frame. Its height and width dimensions correspond to the folding support frame 201, and it is fixed to the starting end of the track unit 101 with a pin or bolt. This solution can limit the effective stroke of the track unit 101 by designing the first fixing frame 202 and the second fixing frame 203, ensuring that the side folding frame 2011 is expanded or folded within the effective stroke range, thereby preventing the side folding frame 2011 from slipping off the track unit 101.

[0028] As a preferred solution of this embodiment, an automatic push-pull unit is provided on the side folding frame, and the automatic push-pull unit includes a pulley group 204 and an electric winch 205. The pulley group 204 includes multiple pulleys, which are respectively fixed on the first fixing frame 202 and the second fixing frame 203. Figure 1 As shown, the pulley group 204 includes four pulley groups, two of which are arranged in the vertical direction and fixed on the first fixed frame 202, and the other two pulley groups 204 are arranged in the vertical direction and fixed on the side fixed frame of the second fixed frame 203. The rope 206 of the electric winch 205 is connected to the lateral folding frame 2011 and is wound around the pulley group 204 to perform tension reversal, thereby realizing the expansion or folding operation of the lateral folding frame 2011. In this embodiment, the electric winch 205 preferably includes two electric winches 205, and the two electric winches 205 share a rope 206. The two ends of the rope 206 are respectively connected to the corresponding electric winch 205 after the tension is reversed by the pulley group 204.

[0029] When in use, the two electric winches 205 are started, one of which enters the winding state and the other enters the output state. At this time, the two electric winches 205 cooperate to move the rope 206, thereby driving the lateral folding frame 2011 connected thereto to move in the expansion or folding direction, realizing automatic pushing and pulling without human intervention.

[0030] As a preferred solution of this embodiment, the lateral folding skeleton 2011 includes columns 2013 and hinged links 2014. The hinged links 2014 are four-links, which are arranged between two adjacent columns 2013. As the four-links are folded and unfolded, the distance between the two adjacent columns 2013 is adjusted, thereby realizing the expansion or folding of the entire lateral folding skeleton 2011.

[0031] As a preferred solution of this embodiment, a plurality of ear plates 103 are equidistantly provided on the outside of the track unit 101. After the lateral folding frame 2011 is unfolded, each column 2013 thereon can overlap with the ear plates 103 at the corresponding position and be fixed by a pin shaft, thereby improving the stability of the shed body 20 after unfolding.

[0032] As a preferred solution of this embodiment, when there are many tank bodies 30, multiple foldable push-pull type protective sheds can be docked and used in combination, such as Figure 2 As shown, this is a schematic diagram of the installation structure of two foldable push-pull protective sheds preferably in this embodiment after being combined on the top surface of the tank body 30. As can be seen from the figure, the shed body 20 formed after the two foldable push-pull protective sheds are combined can cover multiple tank bodies 30, and when combined, the tails of the two foldable push-pull protective sheds are docked, so that they can share the same first fixing frame 202; there will be a 200mm gap (also called a gap) between the two foldable push-pull protective sheds after docking, and the gap can be covered with a protective tarpaulin 40 to close it, or a flap (not shown in the figure) is provided at the end of the folding support frame 201 of the foldable push-pull protective shed, and the gap between the two adjacent foldable push-pull protective sheds can be covered and closed by reversing the flap on the folding support frame 201 of at least one side, that is, the left foldable push-pull protective shed or the right foldable push-pull protective shed.

[0033] Specifically, the flap can be fixed on the column 2013 near the end of the folding support frame 201 through a torsion spring shaft or a hinge shaft. In the initial state, the flap can overlap with the column 2013. When the gap needs to be covered, the flap can be manually swung and rotated to cover the gap. It can be understood that the flap should be arranged on the side and top of the folding support frame 201 at the same time, and the width of the flap should be between 100-200mm to ensure that the gap can be covered.

[0034] It should be noted that the unfolded size of the protective shed in this solution is preferably 12m×12m×2.35m, and the collapsed size is 3m×12m×2.35m, which is convenient for lifting and transportation.

[0035] For 70 drilling rigs, such as Figure 2As shown, there are 6 tank bodies 30 at the rear, the size of a single tank body 30 is 3 meters × 12 meters, and the total size of the 6 tank bodies 30 is about 18 meters × 12 meters, so only 2 sets are needed; after the tank bodies 30 are placed, two sets of foldable push-pull protective shed lower guide brackets are installed on the tank surface, the shed body is hoisted to the lower guide bracket, and it is pulled open along the track unit to cover the 6 tank surfaces at one time.

[0036] Specific uses include:

[0037] During installation, determine the required number of protective sheds. First, detachably fix the guide bracket 10 to the top surface of the tank body 30 through the bracket 102. At the same time, weld the first fixing bracket 202 to the end of the guide bracket 10, that is, the track unit 101. Then, use a crane to hoist the folding support frame 201 and the second fixing bracket 203 above the tank body 30, with their bottoms contacting the track unit 101 on the guide bracket 10. Then, fix the second fixing bracket 203 to the track unit 101 using a pin. Finally, install the pulley block 204 and electric winch 205 on the automatic push-pull unit.

[0038] When pushing or pulling: the two electric winches 205 are started, one enters the reeling state and the other enters the output state. At this time, the two electric winches 205 cooperate to move the rope 206, thereby driving the lateral folding frame 2011 connected thereto to move in the expansion or folding direction;

[0039] During transportation: first fold the shed body 20, then separate the second fixing frame 203 from the track unit 101, and finally use a crane to carry the second fixing frame 203 and the folding support frame 201 to a designated location for transportation.

[0040] From the above analysis, it can be seen that the protective shed in this embodiment is composed of a guide bracket 10 and a shed body 20 to form a push-pull folding structure. Compared with the traditional lifting type protective shed structure, on the one hand, it can realize the effective expansion of the shed body 20 structure, so that it can cover more tank bodies 30, effectively reducing the design cost of the shed body 20; on the other hand, it is easy to fold and hoist, which provides convenience for subsequent moving and installation, and solves the existing deficiencies.

[0041] The above is only an embodiment of the present invention. The commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several improvements can be made without departing from the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of the claims. The specific implementation methods and other records in the specification can be used to interpret the content of the claims.
