DETAILED DESCRIPTION

[0029] It should be noted that the embodiments and technical features in the present application can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as the explanation and illustration of the purpose of the present application, and should not be regarded as improper limitation on the present application.

[0030] In the description of the embodiments of the present application, it should be noted that the orientation or position relationship indicated by the terms "height direction", "top", "bottom" and the like is based on the orientation or position relationship shown in the drawings. These orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. The present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0031] The present application provides a kind of petroleum production equipment, petroleum production equipment includes control room 100, control room 100 can be set up various control equipment, and accommodate operator observes the operation of petroleum production equipment in control room 100.

[0032] The control room 100 provided by the present application, please refer to Figures 1 to 2 , control room 100 includes mounting seat 1, cabin body 2, telescopic mechanism 3 and limiting mechanism 4.Cabin body 2 is arranged above mounting seat 1.Telescopic mechanism 3 is arranged in mounting seat 1, and telescopic mechanism 3 is used to drive cabin body 2 to move along the height direction of control room 100.Limiting mechanism 4 includes driving piece 41 and limiting piece 42, limiting piece 42 includes avoidance state and limiting state, and driving piece 41 is used to drive limiting piece 42 to switch between avoidance state and limiting state.In avoidance state, limiting piece 42 avoids the movement of cabin body 2 in height direction.In limiting state, at least part of the structure of limiting piece 42 is below cabin body 2, which can be used to limit the position of cabin body 2 in height direction.

[0033] The mounting base 1 is a structure arranged at the bottom of the control room 100, and is used to support the cabin 2 and other equipment of the control room 100. The specific structure of the mounting base 1 is not limited here. Generally, the mounting base 1 should have a certain rigidity and not be easily deformed under stress. The mounting base 1 should also have a certain weight to reduce the possibility of the overall control room 100 overturning.

[0034] In some embodiments, the cabin 2 is a frame structure built by welding several steel beams. The structure is simple, and the use of materials can be reduced while ensuring the structural strength, thereby reducing the manufacturing cost.

[0035] In some other embodiments, a plurality of leveling legs, such as hydraulic leveling legs or screw leveling legs, are further arranged on the mounting base 1. The leveling legs are used to support the mounting base 1, and in the case that the supporting surface is uneven, the length of each leveling leg is changed to keep the top surface of the mounting base 1 horizontal.

[0036] In some other embodiments, a moving device, such as a pulley, is arranged at the bottom of the mounting base 1, and the control room 100 can be moved to the working area by the moving device.

[0037] The cabin 2 is a structure having a certain accommodation space for accommodating equipment and operating personnel. The specific structure of the cabin 2 is not limited here, and the size of the cabin 2 is determined according to the size of the equipment arranged in the cabin 2 and the number of operating personnel required, which is not limited here.

[0038] For example, the cabin 2 is a box structure built by a plurality of construction boards. The construction boards can be made of steel plates, and each construction board is built to form the cabin 2 by welding, which is simple in structure. The construction board can also be a sandwich board formed by sandwiching a thermal insulation layer between two metal skins, and each sandwich board is formed into the cabin 2 by riveting or bonding. In this way, the cabin 2 has a certain thermal insulation effect and is relatively light in weight. A hatch can be provided on the cabin 2 for personnel to enter and exit. The cabin 2 is also provided with an observation window 25, which is conducive to lighting and allows the operating personnel to observe the external working environment.

[0039] The telescopic mechanism 3 is arranged between the cabin 2 and the mounting base 1, and is used to drive the cabin 2 to move in the height direction. By extending, the telescopic mechanism 3 drives the cabin 2 to rise in the height direction to avoid obstacles in front of the observation window 25 of the cabin 2, thereby increasing the observation field of view of the cabin 2. By retracting, the telescopic mechanism 3 reduces the height of the cabin 2 to reduce the overall height of the control room 100, which is conducive to the transportation and storage of the control room 100. The specific structure of the telescopic mechanism 3 is not limited here, and any structure that can move back and forth in one direction and can bear a certain load can be used, such as a gear and rack structure, a hydraulic oil cylinder structure, etc.

[0040] The limiting mechanism 4 is a structure for limiting the movement of the cabin body 2. The limiting mechanism 4 changes the state of the limiting part 42 to realize the avoidance and limitation of the movement of the cabin body 2. The specific structure of the limiting part 42 is not limited here.

[0041] The avoidance state refers to that, within the movement range of the cabin body 2 in the height direction, the limiting part 42 does not interfere with the cabin body 2 in the height direction, and the cabin body 2 can move freely in the height direction.

[0042] The limiting state refers to that, within the movement range of the cabin body 2 in the height direction, the limiting part 42 interferes with the cabin body 2 in the height direction. More specifically, the limiting part 42 interferes with the cabin body 2 below the cabin body 2. When the cabin body 2 is lifted by a certain distance, at least part of the structure of the limiting part 42 is arranged below the cabin body 2. When the cabin body 2 moves downward, the structure of the limiting part 42 interferes with the cabin body 2, thereby blocking the downward movement of the cabin body 2 and limiting the position of the cabin body 2 in the height direction.

[0043] It should be noted that the source of the supporting force for maintaining the support of the cabin body 2 after being lifted to the set position is not limited here. For example, the supporting force can be provided by the telescopic mechanism 3 alone, and the limiting mechanism 4 does not contact the cabin body 2 and does not provide the supporting force. Alternatively, the telescopic mechanism 3 does not provide the supporting force, and the cabin body 2 is supported by the limiting mechanism 4 alone. Of course, the telescopic mechanism 3 and the limiting mechanism 4 can also support together.

[0044] The specific type of the driving part 41 is not limited here, which can provide a driving force for the limiting part 42 to change the working state of the driving limiting part 42. For example, the driving part 41 can be a servo motor, a cylinder structure, a hydraulic cylinder structure, etc.

[0045] The control room 100 and the petroleum production equipment provided by the present application change the position of the cabin body 2 in the height direction by arranging the telescopic mechanism 3 below the cabin body 2 and telescoping the telescopic mechanism 3, thereby adjusting the field of view of the cabin body 2 and increasing the field of view of the control room 100. The limiting mechanism 4 with the limiting state and the avoidance state is arranged below the cabin body 2. The limiting part 42 can avoid the cabin body 2 when the cabin body 2 is lifted, and protect the cabin body 2 after the cabin body 2 is lifted. In the limiting state, when the telescopic mechanism 3 fails, the limiting part 42 supports and protects the cabin body 2, thereby reducing the damage to the cabin body 2 and the operator caused by the falling of the cabin body 2 from a high position, and the structure is simple and effective. Meanwhile, the driving part 41 is arranged to drive the limiting part 42 to switch between the limiting state and the avoidance state, which is also conducive to improving the automation degree of the control room 100.

[0046] In some embodiments, please refer to Figures 1 to 2 The limiting part 42 is arranged in a spaced manner with the cabin body 2.

[0047] Here, the limiting piece 42 is spaced apart from the cabin body 2, and the limiting piece 42 is not in contact with the cabin body 2, and the cabin body 2 is independently provided with a supporting force by the telescopic mechanism 3. That is, in normal use, the limiting piece 42 only has part of the structure located below the cabin body 2. At this time, the limiting piece 42 is not in contact with the cabin body 2. The limiting piece 42 only intervenes and is in contact with the lower part of the cabin body 2 when the telescopic mechanism 3 fails to provide a supporting force and falls, thereby supporting the cabin body 2 and limiting the position of the cabin body 2 in the height direction, thereby protecting the safety of the cabin body 2.

[0048] The distance between the limiting piece 42 and the cabin body 2 is not limited here, and the distance only needs to facilitate the smooth movement of part of the structure of the limiting piece 42 to the lower part of the cabin body 2 and away from the lower part of the cabin body 2 when the limiting piece 42 is switched between the limiting state and the avoiding state.

[0049] It should be noted that the distance should be as small as possible under the premise of ensuring smooth switching of the working state of the limiting piece 42. In this way, when the telescopic mechanism 3 fails to provide a supporting force, the smaller the distance, the smaller the falling height of the cabin body 2, and the smaller the impact of the falling of the cabin body 2 and the operator in the cabin body 2, which is beneficial to reduce the damage to the cabin body 2 and the personnel.

[0050] By spacing the limiting piece 42 from the cabin body 2, part of the structure of the limiting piece 42 can smoothly move or move away from the lower part of the cabin body 2 when the limiting piece 42 is switched between the limiting state and the avoiding state. The limiting piece 42 is spaced apart from the cabin body 2, and when the telescopic mechanism 3 fails, the limiting piece 42 intervenes to block the falling of the cabin body 2, thereby protecting the safety of the cabin body 2 and the operator.

[0051] In some embodiments, please refer to Figure 2 and Figure 4 In the avoiding state, the projection of the limiting piece 42 does not overlap the projection of the cabin body 2 in the plane perpendicular to the height direction. In the limiting state, the projection of the limiting piece 42 overlaps the projection of the cabin body 2 in the plane perpendicular to the height direction.

[0052] In the avoiding state, the projection of the limiting piece 42 does not overlap the projection of the cabin body 2 in the plane perpendicular to the height direction, that is, in the height direction, the structure of the cabin body 2 does not interfere with the structure of the limiting piece 42, so that the cabin body 2 can move freely in the height direction in the avoiding state.

[0053] In the limiting state, the projection of the limiting member 42 and the projection of the cabin body 2 have an overlapping area in the plane perpendicular to the height direction, that is, in the height direction, the structure of the cabin body 2 interferes with the structure of the limiting member 42, for example, part of the structure of the limiting member 42 can extend below the cabin body 2, so that the cabin body 2 cannot move freely in the height direction, and the position of the cabin body 2 in the height direction is limited.

[0054] By changing the projection relationship between the projection of the limiting member 42 and the projection of the cabin body 2 in the plane perpendicular to the height direction, the working state of the limiting member 42 is changed, the principle is simple, and automatic control is facilitated.

[0055] In some embodiments, referring to Figures 1 to 4 , the limiting member 42 includes a connecting rod 421 and a limiting portion 422 arranged on the connecting rod 421, the connecting rod 421 extends along the height direction, one end of the connecting rod 421 is connected with the limiting portion 422, and the other end is connected with the driving member 41.

[0056] The limiting portion 422 is a structure of the limiting member 42 that extends into the bottom of the cabin body 2 to limit the cabin body 2, and the specific structure is not limited here. In the avoiding state, the projection of the limiting member 42 and the projection of the cabin body 2 have no overlapping area in the plane perpendicular to the height direction. That is, the limiting portion 422 is away from the bottom of the cabin body 2, and the projection of the limiting portion 422 and the projection of the cabin body 2 have no overlapping area in the plane perpendicular to the height direction.

[0057] In the limiting state, the projection of the limiting member 42 and the projection of the cabin body 2 have an overlapping area in the plane perpendicular to the height direction. That is, the limiting portion 422 extends into the bottom of the cabin body 2, and the projection of the limiting portion 422 and the projection of the cabin body 2 have an overlapping area in the plane perpendicular to the height direction.

[0058] The connecting rod 421 is a rod-shaped structure, one end of the connecting rod 421 is connected with the limiting portion 422, and the other end is connected with the driving member 41. The driving member 41 drives the connecting rod 421 to change the state of the limiting portion 422, thereby changing the working state of the limiting member 42.

[0059] The form of the driving member 41 driving the connecting rod 421 is not limited here, and the position relationship between the projection of the limiting portion 422 and the projection of the cabin body 2 in the plane perpendicular to the height direction can be changed.

[0060] Exemplarily, the limiting member 42 is in the shape of a flag as a whole, the limiting part 422 is in the shape of a plate, one side of the limiting part 422 is provided with a mounting hole, and the limiting part 422 is sleeved on one side of the connecting rod 421. The limiting part 422 can be connected with the connecting rod 421 by welding, or can be connected with the connecting rod 421 by screwing through the mounting hole.

[0061] By providing the limiting part 422 and the connecting rod 421 on the limiting member 42, the driving member 41 changes the position relationship between the projection of the limiting part 422 on the plane perpendicular to the height direction and the projection of the cabin body 2 on the plane perpendicular to the height direction, so as to realize the change of the working state of the limiting member 42, which is simple in structure and is conducive to the setting and maintenance of the limiting member 42.

[0062] In some embodiments, referring to Figures 1 to 4 , the driving member 41 drives the connecting rod 421 to rotate around the central axis of the connecting rod 421, and drives the limiting member 42 to switch between the avoiding state and the limiting state.

[0063] By driving the connecting rod 421 to rotate around the central axis of the connecting rod 421 by the driving member 41, the rotation of the limiting part 422 provided at one end of the connecting rod 421 is driven, the position relationship between the projection of the limiting part 422 on the plane perpendicular to the height direction and the projection of the cabin body 2 on the plane perpendicular to the height direction is changed, and the change of the working state of the limiting member 42 is realized, which is simple in structure principle.

[0064] In the above embodiment in which the limiting member 42 is in the shape of a flag as a whole, the limiting part 422 is in the shape of a plate, and the connecting rod 421 is provided on the side surface of the cabin body 2. In the avoiding state, the connecting rod 421 is rotated to the plate surface of the limiting part 422 parallel to the side surface of the cabin body 2, and in the projection on the plane perpendicular to the height direction, the projection of the limiting part 422 and the projection of the cabin body 2 have no overlapping area. In the limiting state, the connecting rod 421 is rotated to the plate surface of the limiting part 422 intersecting with the side surface of the cabin body 2, and in the projection on the plane perpendicular to the height direction, the projection of the limiting part 422 and the projection of the cabin body 2 have an overlapping area.

[0065] In some embodiments, referring to Figures 1 to 4The control chamber 100 comprises two limit members 42, the driving member 41 comprises a first oil cylinder 411 and two transmission rods 412, the first oil cylinder 411 comprises a first cylinder barrel 4111 and two first piston rods 4112. The two first piston rods 4112 are respectively arranged at two ends of the first cylinder barrel 4111, and the first cylinder barrel 4111 is in sliding fit with the two first piston rods 4112 along a first direction. One end of the transmission rod 412 is connected with a free end of the first piston rod 4112, and the other end is connected with the connecting rod 421. The first piston rod 4112 drives the transmission rod 412 to move along the first direction, and the transmission rod 412 drives the connecting rod 421 to rotate around the central axis of the connecting rod 421, wherein the height direction intersects the first direction.

[0066] Here, the first oil cylinder 411 is a double-rod oil cylinder structure. The double-rod oil cylinder structure is to arrange two piston rods at two ends of a cylinder barrel respectively. The two piston rods can be controlled synchronously to move along the same direction, for example, one piston rod extends in one direction, and the other piston rod at the other end retracts along the direction. Of course, the extension or retraction of each piston rod can also be controlled individually.

[0067] The transmission rod 412 is a rod-shaped structure arranged between the first piston rod 4112 and the connecting rod 421, and the transmission rod 412 can convert the linear thrust of the first piston rod 4112 into the rotation torque required for the rotation of the connecting rod 421. The specific structure of the transmission rod 412 is not limited here, and any structure that can convert the linear thrust of the first piston rod 4112 into the rotation torque required for the rotation of the connecting rod 421 is acceptable.

[0068] For example, please refer to Figure 4 The bottom of the connecting rod 421 extends perpendicularly to the height direction to form a rotating arm 4211, and the two ends of the connecting rod 421 are respectively hinged to the rotating arm 4211 and the first piston rod 4112. In this way, the linear thrust of the first piston rod 4112 can be transmitted to the rotating arm 4211 through the transmission rod 412, and the rotating arm 4211 converts the received thrust into torque to drive the connecting rod 421 to rotate around the central axis of the connecting rod 421.

[0069] In some embodiments, the transmission rod 412 comprises a main body part 4121 and a bending part 4122 arranged at one end of the main body part 4121, and the bending part 4122 is hinged to the first piston rod 4112. In this way, on the one hand, the main body part 4121 cannot be collinear with the first piston rod 4112 during transmission, avoiding the occurrence of transmission dead points. On the other hand, there is a certain distance between the action point of the first piston rod 4112 and the main body part 4121, forming a force arm, which is beneficial to reduce the transmission resistance of the first piston rod 4112.

[0070] Here, it should be noted that the two first piston rods 4112 are in sliding fit with the first cylinder barrel 4111, and the movement directions of the two first piston rods 4112 can be the same direction or opposite directions. In different movement conditions, the setting angle of the limiting portion 422 on the connecting rod 421 can be adjusted so that the limiting portion 422 is in the corresponding position in the corresponding working state.

[0071] In some embodiments, two limiting structures are correspondingly arranged on opposite sides of the cabin body 2, so that the safety of the limiting mechanism 4 is further improved.

[0072] By setting the driving member 41 as the first oil cylinder 411, the first piston rod 4112 of the first oil cylinder 411 drives the transmission rod 412 to rotate the connecting rod 421, so as to change the different working states of the limiting member 42. The structure is simple, which is conducive to reducing the manufacturing cost.

[0073] In some embodiments, please refer to Figures 1 to 4 , the telescopic mechanism 3 includes a second oil cylinder 31, the second oil cylinder 31 includes a second cylinder barrel 311 and a second piston rod 312 in sliding fit along the height direction, the second cylinder barrel 311 is connected with the mounting base 1, and the second piston rod 312 is connected with the cabin body 2. The second piston rod 312 drives the cabin body 2 to move along the height direction.

[0074] For example, four second oil cylinders 31 are arranged at the four corners of the cabin body 2, and the four second oil cylinders 31 jointly drive the cabin body 2 to move along the height direction, which is conducive to the stable lifting of the cabin body 2 and also reduces the load borne by each second oil cylinder 31.

[0075] By setting the telescopic mechanism 3 as the second oil cylinder 31, the movement of the cabin body 2 is driven by the hydraulic oil cylinder structure, which is conducive to the setting of a cabin body 2 with a large weight. At the same time, the hydraulic oil cylinder structure can have a self-locking function, which is conducive to providing continuous support force for the cabin body 2.

[0076] In some embodiments, please refer to Figures 1 to 4 , the cabin body 2 is provided with a first containing cavity 21 along the height direction, the bottom of the first containing cavity 21 is provided with a first opening 211, and the second piston rod 312 extends into the first containing cavity 21 through the first opening 211 and is connected with the cabin body 2.

[0077] The first containing cavity 21 is a semi-closed structure arranged on the cabin body 2 and used for containing the second piston rod 312. The specific structure of the first containing cavity 21 is not limited here, as long as it can contain the second piston rod 312 and can reserve a space for connecting the second piston rod 312 to the cabin body 2 in the first containing cavity 21.

[0078] The size of the first accommodating cavity 21 is not limited here, and the first accommodating cavity 21 can at least accommodate part of the second piston rod 312.

[0079] The size of the first accommodating cavity 21 in the height direction is determined according to the length of the second piston rod 312. Generally, in order to protect the second piston rod 312, the first accommodating cavity 21 can accommodate the entire second piston rod 312.

[0080] The first opening 211 is a structure provided at the bottom of the first accommodating cavity 21, and the first opening 211 communicates the first accommodating cavity 21 with the outside, and the second piston rod 312 can extend into the first accommodating cavity 21 through the first opening 211. The structure and size of the first opening 211 are not limited here, and the second piston rod 312 can extend into the first accommodating cavity 21.

[0081] The specific connection mode of the second piston rod 312 and the cabin body 2 is not limited here, and here, it is necessary to point out that the weight of the cabin body 2 directly acts on the connection between the cabin body 2 and the second piston rod 312, and the connection should have a certain strength.

[0082] For example, the second piston rod 312 and the cabin body 2 are connected by a pin shaft, and the second piston rod 312 can rotate relative to the cabin body 2 within a certain range around the pin shaft. In this way, the second piston rod 312 and the cabin body 2 are movably connected, reducing the shear force caused by the perpendicularity error when the second piston rod 312 supports the cabin body 2, and damaging the second piston rod 312.

[0083] By setting the first accommodating cavity 21, the second piston rod 312 is connected to the cabin body 2 by extending into the first accommodating cavity 21, so that the influence of the external environment such as dust, rain, and external force impact on the second piston rod 312 is reduced, and the protection of the second piston rod 312 is realized.

[0084] In some embodiments, please refer to Figure 3 The mounting seat 1 is provided with a second accommodating cavity 11 in the height direction, and the top of the second accommodating cavity 11 is provided with a second opening 111. The second cylinder barrel 311 extends into the second accommodating cavity 11 through the second opening 111 and is connected to the mounting seat 1.

[0085] The second accommodating cavity 11 is a semi-closed structure provided on the mounting seat 1 and used for accommodating the second cylinder barrel 311. The specific structure of the second accommodating cavity 11 is not limited here, and it is only required to be capable of accommodating the second cylinder barrel 311 and reserving a space for connecting the second cylinder barrel 311 to the mounting seat 1 in the second accommodating cavity 11.

[0086] The size of the second accommodating cavity 11 is not limited here, and the second accommodating cavity 11 can at least accommodate part of the second cylinder barrel 311.

[0087] The size of the second accommodating cavity 11 in the height direction is determined according to the length of the second cylinder 311. Generally, the second cylinder 311 is completely accommodated in the second accommodating cavity 11 for protection.

[0088] The second opening 111 is arranged on the top of the second accommodating cavity 11, and the second opening 111 is connected with the outside. The second cylinder 311 can extend into the second accommodating cavity 11 through the second opening 111. The structure and size of the second opening 111 are not limited here, and the second cylinder 311 can extend into the second accommodating cavity 11.

[0089] The specific connection mode of the second cylinder 311 and the mounting base 1 is not limited here, and any structure that can stably connect the second cylinder 311 can be used.

[0090] By arranging the second accommodating cavity 11, the second cylinder 311 extends into the first accommodating cavity 21 and is connected with the mounting base 1. In this way, the cabin 2 connected with the second oil cylinder 31 is stably connected to the mounting base 1 through the second cylinder 311. The arrangement of the second accommodating cavity 11 is also beneficial to reducing the influence of the external environment on the second cylinder 311 and protecting the second cylinder 311.

[0091] In some embodiments, please refer to Figures 1 to 4 The cabin 2 comprises a first guide sleeve 22 arranged at the first opening 211. At least part of the second cylinder 311 extends into the first accommodating cavity 21 through the first guide sleeve 22 and is in sliding fit with the first guide sleeve 22 in the height direction. The first guide sleeve 22 is used for limiting the circumferential direction of the second cylinder 311.

[0092] Here, the second cylinder 311 extends into the first accommodating cavity 21 through the first guide sleeve 22. On the one hand, the second cylinder 311 at the bottom of the second oil cylinder 31 can also extend into the first accommodating cavity 21, thereby expanding the movement range of the cabin 2 in the height direction. On the other hand, the bottom of the second cylinder 311 extends into the second accommodating cavity 11 through the second opening 111, and the top of the second cylinder 311 also extends into the first accommodating cavity 21 through the first opening 211. That is, the bottom of the cabin 2 can move along the second cylinder 311 to the top of the mounting base 1. In this way, when the cabin 2 is retracted, it can be as close as possible to the mounting base 1 in the height direction, thereby reducing the height of the control room 100 when retracted, which is beneficial to the transportation and storage of the control room 100.

[0093] In some embodiments, at least part of the second cylinder 311 extends into the first accommodating cavity 21 when the cabin 2 is raised to the highest point. That is, the first guide sleeve 22 is in sliding fit with the second cylinder 311 during the extension and retraction of the cabin 2.

[0094] The first guide sleeve 22 is arranged at the opening and is used to close the gap between the first opening 211 and the second cylinder 311. On one hand, the first accommodating cavity 21 can be closed, and the external substances can be prevented from entering and affecting the movement of the second piston rod 312. On the other hand, the first guide sleeve 22 is in sliding fit with the second cylinder 311, and the guide sleeve limits the second cylinder 311 in the axial direction. In turn, the second cylinder 311 also limits the cabin 2 connected with the first guide sleeve, so that the cabin 2 can be guided to move along the height direction limited by the second cylinder 311 during the extension and retraction process, the cabin 2 can be prevented from shaking with the second oil cylinder 31 in the circumferential direction of the second oil cylinder 31 during the extension and retraction process, the stability of the cabin 2 during the movement is improved, and the influence of the shear force on the second piston rod 312 is reduced.

[0095] In the above embodiment in which the second cylinder 311 at least partially extends into the first accommodating cavity 21 when the cabin 2 is lifted to the highest point, the first guide sleeve 22 is in sliding fit with the second cylinder 311 during the movement of the cabin 2, so that the second cylinder 311 can limit the cabin 2 during the movement, and the stability of the cabin 2 during the movement is improved.

[0096] The specific structure of the first guide sleeve 22 is not limited here. For example, the first guide sleeve 22 is a plate-shaped structure, and the first guide sleeve 22 closes the first opening 211. The first guide sleeve 22 is provided with an opening corresponding to the second cylinder 311, and the second cylinder 311 is in sliding fit with the first guide sleeve 22.

[0097] In some embodiments, since the opening of the first guide sleeve 22 needs to be in sliding fit with the second cylinder 311, in order to improve the smoothness of the sliding fit, a wear-resistant and self-lubricating material can be arranged on the first guide sleeve 22 to directly cooperate with the second cylinder 311, so as to improve the sliding fit effect. For example, the wear-resistant plastic can be used.

[0098] For example, referring to Figure 3 , the first guide sleeve 22 is annularly provided with an annular groove 221, a guide ring 23 made of wear-resistant plastic is arranged in the annular groove 221, a cover plate 24 is arranged on the side of the guide ring 23 extending into the first guide sleeve 22, and the cover plate 24 is connected with the first guide sleeve 22. The cover plate 24 extends to the side of the annular groove 221 to form a protrusion, and the guide ring 23 is fixed by abutting against the protrusion on the cover plate 24. The guide ring 23 is in sliding fit with the second cylinder 311 and limits the circumferential direction of the second cylinder 311.

[0099] By arranging the first guide sleeve 22 at the first opening 211, the first guide sleeve 22 is in sliding fit with the second oil cylinder 31, and the circumference of the second oil cylinder 31 is limited, so that the second oil cylinder 31 can limit the cabin body 2, reduce the shaking of the cabin body 2 with the second oil cylinder 31 in the circumferential direction of the second oil cylinder 31 during the extension and retraction process, improve the stability of the cabin body 2 during the extension and retraction process, and also reduce the influence of the shearing force on the second piston rod 312, thereby improving the use safety of the second oil cylinder 31.

[0100] In some embodiments, referring to Figures 1 to 4 , the mounting seat 1 includes a fixing piece 12 and a connecting piece 13 arranged at the bottom of the second accommodating cavity 11, the fixing piece 12 is arranged at the bottom of the connecting piece 13 and is in fastening connection with the connecting piece 13, the connecting piece 13 has a through hole 121 penetrating the connecting piece 13 in the height direction, the second cylinder barrel 311 includes a cylinder barrel body 3111 and a connecting protrusion 3112 arranged at the bottom of the cylinder barrel body 3111. The connecting protrusion 3112 penetrates the through hole 121 and is in fastening connection with the fixing piece 12, and the bottom of the cylinder barrel body 3111 is arranged in spaced manner with the side of the connecting piece 13 away from the fixing piece 12.

[0101] For example, the fixing piece 12 is in block structure, and the fixing piece 12 is matched with the bottom of the second accommodating cavity 11, and the fixing piece 12 is fixed at the bottom of the second accommodating cavity 11 by fasteners.

[0102] The fixing piece 12 has a through hole 121 penetrating the fixing piece 12 in the height direction, so that the second cylinder barrel 311 can abut against the connecting piece 13 through the through hole 121 of the fixing piece 12.

[0103] For example, the connecting piece 13 is in plate structure. In some embodiments, the connecting piece 13 is provided with a protrusion at the position matched with the through hole 121 of the fixing piece 12, and the protrusion extends into the through hole 121 and is connected with the connecting protrusion 3112 of the second cylinder barrel 311 by fasteners.

[0104] It should be noted that the fixing piece 12, the connecting piece 13 and the connecting protrusion 3112 are in fixed connection, for example, by bolt connection. The force of the second oil cylinder 31 is transmitted to the connecting piece 13, the force of the connecting piece 13 is transmitted to the fixing piece 12 by bolts, and the force of the fixing piece 12 is transmitted to the mounting seat 1.

[0105] Here, the bottom side of the fixing piece 12 and the side of the connecting piece 13 facing the fixing piece 12 can be machined to improve the machining accuracy of the bottom side of the fixing piece 12 and the side of the connecting piece 13 facing the fixing piece 12, thereby improving the levelness of the installation of the bottom of the oil cylinder.

[0106] ​The connecting protrusion 3112 is a structure arranged at the bottom of the second cylinder barrel 311 for cooperating with the through hole 121, and the structure size of the connecting protrusion 3112 is determined by the structure of the through hole 121, which is not limited here.

[0107] Here, in the cross section perpendicular to the height direction, the cross-sectional shape of the through hole 121 is the same as that of the connecting protrusion 3112, for example, both are circular.

[0108] The connecting protrusion 3112 penetrates the through hole 121 and abuts against the connecting piece 13, and is fastened to the connecting piece 13, and the processing accuracy of the contact surface between the connecting protrusion 3112 and the connecting piece 13 can be improved, thereby improving the levelness of the installation of the second cylinder barrel 311 at the bottom.

[0109] In addition, the processing accuracy of the side wall of the through hole 121 and the circumferential side wall of the connecting protrusion 3112 can also be improved to improve the assembly reliability between the connecting protrusion 3112 and the through hole 121.

[0110] By arranging the fixing piece 12 and the connecting piece 13, the connecting piece 13 is fastened to the bottom side of the fixing piece 12, so as to facilitate ensuring the levelness between the fixing piece 12 and the connecting piece 13, and the second cylinder barrel 311 can abut against the connecting piece 13 through the through hole 121 of the fixing piece 12, thereby facilitating improving the levelness between the piston rod and the connecting piece 13, that is, facilitating improving the levelness of the installation of the second oil cylinder 31.

[0111] The bottom of the cylinder barrel body 3111 is arranged in a spaced manner with the side of the connecting piece 13 away from the fixing piece 12, that is, the cylinder barrel body 3111 is arranged in a spaced manner with the inner side surface of the fixing piece 12, that is, the cylinder barrel body 3111 does not abut against the inner side surface of the fixing piece 12, but abuts against the connecting piece 13 through the connecting protrusion 3112.

[0112] For example, the spacing between the bottom of the cylinder barrel body 3111 and the side of the fixing piece 12 away from the connecting piece 13 is 2mm-10mm, for example, 2mm, 2.2mm, 2.5mm, 2.6mm, 2.8mm, 3mm, 3.2mm, 3.5mm, 3.8mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, etc.

[0113] By setting the spacing between the bottom of the cylinder barrel body 3111 and the side of the fixing piece 12 away from the connecting piece 13 to be 2mm-10mm, it is not only conducive to the smooth abutment of the second cylinder barrel 311 and the connecting piece 13 through the connecting protrusion 3112, but also can improve the structural strength of the second cylinder barrel 311.

[0114] Here, the machining accuracy of the bottom side of the fixing member 12 and the side of the connecting member 13 facing the fixing member 12 can be improved by machining the bottom side of the fixing member 12 and the side of the connecting member 13 facing the fixing member 12, thereby improving the levelness of the installation at the bottom of the hydraulic cylinder.

[0115] In some embodiments, please refer to Figure 3 The mounting base 1 includes a second guide sleeve 14, which is disposed at the second opening 111. At least a portion of the second cylinder 311 extends into the second receiving cavity 11 through the second guide sleeve 14. The second guide sleeve 14 is used to limit the circumferential movement of the second cylinder 311.

[0116] The specific structure of the second guide sleeve 14 is not limited here. For example, the second guide sleeve 14 has a plate-like structure and closes the second opening 111. The second guide sleeve 14 is provided with an opening corresponding to the second cylinder 311.

[0117] It should be noted that the second guide sleeve 14 and the first guide sleeve 22 have the same limiting effect on the second cylinder 311 in the circumferential direction.

[0118] By setting a second guide sleeve 14 at the second opening 111, the second guide sleeve 14 slides with the second hydraulic cylinder 31 to limit the circumferential movement of the second hydraulic cylinder 31. In this way, the second hydraulic cylinder 31 can be limited on the mounting base 1, reducing the movement of the cabin 2 and the second hydraulic cylinder 31 during the extension and retraction process, improving the stability of the cabin 2 during the extension and retraction process, and also reducing the influence of shear force on the second piston rod 312, thereby improving the safety of the second hydraulic cylinder 31 in use.

[0119] In some embodiments, please refer to Figures 1 to 4 The cabin 2 is provided with an observation window 25, and the observation window 25 is at least the upper part of the curved section 251, which protrudes outward from the cabin 2.

[0120] The observation window 25 is a structure provided on the cabin 2 for observing the external working environment of the control room 100. The specific structure of the observation window 25 is not limited here. For example, an opening is provided on one side of the cabin 2, and the opening is covered with glass to form the observation window 25. It can be understood that the larger the opening, the larger the area of ​​the observation window 25, and the larger the corresponding field of view.

[0121] Here, "upper part" refers to the structure of the observation window 25 above the center line of the observation window 25 in the height direction. The curved section 251 protrudes outward from the cabin 2, that is, the curved end extends into the cabin 2 while extending in the height direction. In this way, the field of view of the operator inside the cabin 2 can be expanded, thereby increasing the operator's field of vision.

[0122] It should be noted that the length of the curved segment 251 is not limited here. For example, the curved segment 251 can be set at the top of the observation window 25 near the opening, or the entire observation window 25 can be a curved segment 251.

[0123] By providing an observation window 25 on the cabin 2, it is beneficial for the operators inside the cabin 2 to observe the external working environment of the control room 100. By providing an arc section 251 at least at the top of the observation window 25, the operator's field of vision is increased, which is conducive to obtaining more external information.

[0124] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
