Description

Technical Field

[0001] The present application relates to the technical field of sunshade bodies arranged on the top surface of a mud tank, and in particular to a side-lifting sunshade body on the top of a mud tank. Background Art

[0002] Mud tanks are mainly used in oil drilling, directional drilling, coal gas exploration, sewage treatment and other industries. They play a key role in oil drilling. They are an indispensable part of solid control equipment. Their main function is to store and process the mud generated during drilling. The mud is composed of drilling fluid, which plays a variety of roles in the drilling process, such as cooling the drill bit, carrying cuttings, lubricating drilling tools and balancing formation pressure. Mud tanks cooperate with mud agitators, sand pumps and other equipment to form a complete mud circulation system. In this system, the mud is stored in the mud tank after being processed, and then supplied to the drilling rig again, thus realizing the recycling of the mud. This can not only improve drilling efficiency, but also reduce mud waste and environmental impact.

[0003] At present, the top surface operation of mud tank mainly includes monitoring mud liquid level, checking mud quality, maintaining mud agitator, adding chemical agent and cleaning mud tank top surface. These operations need to be performed regularly by staff to ensure the normal operation of mud tank. In the actual operation process, one-way operation takes a long time, which makes the staff stay on the top surface of mud tank for a long time. In order to improve the comfort of the top surface operation of mud tank, a sunshade is usually set on the top surface of mud tank to reduce the high temperature sun exposure and rain infiltration.

[0004] At present, when the mud tanks and the sunshades on the tops are manufactured and processed by the manufacturers, they are sent to the oil field production site. Due to the height of the mud tank body (usually more than 3 meters), the pre-made sunshades are too high. When the sunshades are transported to the oil field site as accessories, the drilling operators need to assemble them on site, which increases the workload of the on-site personnel. At the same time, the oil drilling sites are usually remote. For example, when welding and assembling the sunshades, spot welding is also required, which makes assembly difficult in the later stage. At the same time, transporting the sunshades separately also increases the transportation cost. Summary of the invention

[0005] In response to the above-mentioned problems, the present application aims to provide a side-lifting sunshade body on the top of a mud tank, which can lower the height when transporting the mud tank, thereby solving the problem of excessive transportation height; and after the mud tank is transported to the oil operation site, the sunshade body is adjusted to be lifted on the mud tank and reach a protective height, thereby solving the difficulty of subsequent assembly of the sunshade body by drilling workers.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a side-lifting sunshade body on the top of a mud tank, characterized in that: the sunshade body is vertically adjustable and installed on the top side of the mud tank, and when the sunshade body is driven to adjust, it moves away from or close to the top side of the mud tank, and a driving mechanism for driving the sunshade body to adjust one side compared to the mud tank is also provided at the connection between the sunshade body and the mud tank.

[0007] Preferably, the sunshade body has support rods corresponding to the corners of the mud tank, and support sleeves with positioning pin holes and through which the support rods are passed are arranged on the corners of the mud tank.

[0008] Preferably, the driving mechanism comprises that each of the support rods is hinged to the bottom side of the awning body, and each of the support sleeves is horizontally slidably arranged on the mud tank.

[0009] Preferably, an eccentric limiting wheel in contact with the outer wall of the support rod is also provided on one side of each support sleeve.

[0010] The beneficial effects of the present application are as follows: the awning body is assembled on the mud tank when the mud tank is manufactured, and when the mud tank is transported, the awning body is adjusted to be close to the top surface of the mud tank, thereby solving the problem of excessive transportation height; and after the mud tank is transported to the oil operation site, the awning body is adjusted to be lifted on the mud tank and reach the protective height, that is, the awning body is quickly assembled and formed and is in a protective state, thereby solving the difficulty of subsequent assembly of the awning body by drilling personnel.

[0023] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0024] See attached Figures 1 to 11 The illustrated embodiment is a side-lifting sunshade body on the top of a mud tank, wherein the sunshade body 1 is vertically adjustable and mounted on the top of the mud tank 2, and moves away from or close to the top of the mud tank 2 when the sunshade body 1 is driven for adjustment. The sunshade body 1 is assembled on the mud tank 2 when the mud tank 2 is manufactured through the assembly structure, and when the mud tank 2 is transported, the sunshade body 1 is adjusted to be close to the top surface of the mud tank 2, thereby solving the problem of excessive height during transportation; and after the mud tank 2 is transported to the oil operation site, the sunshade body 1 is adjusted to be lifted on the mud tank 2 and reach the protective height, namely, the sunshade body 1 is quickly assembled and placed in a protective state, thereby solving the difficulty of subsequent assembly of the sunshade body 1 by drilling workers.

[0025] Since the awning body 1 and the mud tank 2 have a large plane structure, it is usually necessary to perform synchronous jacking operations on both sides of the awning body 1 during subsequent jacking. However, synchronous jacking is actually not synchronized, resulting in the stagnation of the awning body 1 after tilting ( Figure 8 In order to solve this problem, the present application also provides a driving mechanism at the connection between the awning body 1 and the mud tank 2 to drive the awning body 1 to adjust one side relative to the mud tank 2. When the awning body 1 is lifted, the driving mechanism can drive one side of the awning body 1 successively, and solve the problem of the awning body 1 being stuck due to deflection when driving on one side, thereby reducing the difficulty of lifting the awning body 1.

[0026] Specifically, Figure 2As shown, the sunshade body 1 has support rods 11 corresponding to the corners of the mud tank 2, and support sleeves 21 with positioning pin holes and through which the support rods 11 are inserted are provided on the corners of the mud tank 2. Figure 3-4 As shown, the support rod 11 is inserted from the support sleeve 21 to the bottom end, so that the awning body 1 is close to the top surface of the mud tank 2 ( Figure 3 The state shown in the figure) is thus reduced on the basis of pre-assembling the awning body 1, and the problem of the height of the awning body 1 and the problem of excessive height during transportation is reduced, and the awning body 1 can be transported in this state. After being transported to the oil operation site, the support rod 11 is driven upward in the support sleeve 21 to lift the awning body 1 ( Figure 5-6 After lifting to the right position, Figure 6 As shown, a pin is inserted into a positioning pin hole (not shown in the figure) of the support sleeve 21 and a support rod 11 is passed through to realize the lifting and fixing of the awning body 1.

[0027] like Figure 8 As shown in FIG. 1 , when the single-side support rod 11 is lifted, the awning body 1 is deflected, so that the support rod 11 is stuck in the support sleeve 21. To solve this problem, as shown in FIG. Fig. 9 As shown, the driving mechanism includes each support rod 11 being hinged to the bottom side of the awning body 1, and each support sleeve 21 being horizontally slidably arranged on the mud tank 2. Fig. 9 As shown, the support rod 11 on one side is driven upward, the awning body 1 on that side rises and deflects, and the support sleeve 21 slides horizontally on the mud tank 2 as the support rod 11 is driven. When the perforation on the bottom side of the support rod 11 corresponds to the positioning pin hole on the support sleeve 21, the pin is inserted to lift the awning body 1 on one side, and then the other side of the awning body 1 is driven to complete the lifting in the same way, thereby realizing the rapid lifting operation of the awning body 1 and solving the problem of jamming between the support rod 11 and the support sleeve 21.

[0028] Since the subsequent operators have to stand on the top side of the mud tank 2 and be located in the sunshade body 1, the height of the support rod 11 is preferably greater than two meters. However, it is difficult to lift the support rod 11 to a height of about two meters at a time. Therefore, in order to solve this problem, Figure 10-11As shown, an eccentric limiting wheel 3 (preferably made of rubber) in contact with the outer wall of the support rod 11 is also provided on one side of each of the support sleeves 21. When the support rod 11 is driven to move upward, it contacts the eccentric limiting wheel 3, causing the small wall thickness section with the rotation center on the surface of the eccentric limiting wheel 3 to contact the support rod 11. After the support rod 11 is driven to rise to a certain height, the downward movement of the support rod 11 drives the eccentric limiting wheel 3 to rotate, so that the large wall thickness section with the rotation center on the surface of the eccentric limiting wheel 3 contacts the support rod 11, thereby squeezing the support rod 11, simultaneously limiting the downward movement of the support rod 11, and limiting the support rod 11 at the lifting height, so that the operator can change hands, and then drive the support rod 11 to achieve lifting in a progressive operation mode one by one, reducing the difficulty of the operator's lifting at one time.

[0029] When the awning body 1 needs to be disassembled later, the rotating axis of the eccentric limiting wheel 3 is preferably passed through the outside of the support sleeve 21, so as to drive the eccentric limiting wheel 3 to make its small wall thickness section correspond to the outer wall of the support rod 11, thereby releasing the extrusion and limiting effect of the large wall thickness section of the eccentric limiting wheel 3 on the outer wall of the support rod 11.

[0030] The principle of the present application is: when making the mud tank 2, the support rod 11 of the awning body 1 is inserted into the support sleeve 21 of the mud tank 2, and the awning body 1 is made close to the top surface of the mud tank 2, and the mud tank 2 is transported in this state; after being transported to the oil operation site, the single-side support rod 11 is driven to rise, and during the rising process, the contact action of the eccentric limiting wheel 3 can realize the successive progressive operation of the support rod 11 to reduce the difficulty of the operator's one-time lifting.

[0031] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
