Description

Technical Field

[0001] This utility model belongs to the field of marine engineering technology, and in particular relates to a mobile transport rack for offshore oil platform cabinets. Background Technology

[0002] Offshore oil platform control panels refer to specialized equipment cabinets installed and used on offshore oil platforms to store and protect electrical, control, and communication systems. Due to the unique working environment of offshore oil platforms, these control panels require corrosion resistance, high reliability, and strong adaptability. Handling racks are used to move these control panels from their storage location to the installation area, or from the installation area to the maintenance location. However, because handling racks in related technologies are customized for specific control panels or platforms, they are difficult to adapt to the handling needs of control panels of different specifications or other types of equipment, resulting in a lack of versatility. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A mobile transport frame for offshore oil platform cabinets includes a support frame, two mobile carriages, two guide structures, two limit baffles, two adjustable distance mechanisms, four mobile components, and eight flexible connection structures.

[0006] Two movable carriages are symmetrically arranged on the left and right sides of the support frame, and two guide structures are arranged side by side. The middle part of the support frame is slidably engaged with the movable carriage through the two guide structures. Each movable carriage is connected to the side of the support frame through an adjustment mechanism. The adjustment mechanism is used to adjust the distance between the movable carriage and the support frame.

[0007] The two limiting baffles are symmetrically arranged on the front and rear end faces of the support frame. The bottom of each limiting baffle is connected to the support frame through four elastic connection structures. The four elastic connection structures located on the same side are symmetrically arranged on the left and right. The limiting baffles are used to position the outer end face of the cabinet shell.

[0008] Two moving components are correspondingly provided at the bottom of each of the moving carriages.

[0009] Furthermore, both the support frame and the movable carriage have C-shaped cross-sections, and the openings of both the support frame and the movable carriage face downwards.

[0010] Furthermore, the adjusting mechanism includes a handwheel, an adjusting screw, and a bearing seat. The adjusting screw passes through the movable slide and is rotatably connected to the bearing seat. The bearing seat is located inside the support frame. The adjusting screw is threadedly connected to the movable slide. The handwheel is located at the outer end of the adjusting screw.

[0011] Furthermore, the guide structure includes a guide slide rod and two limiting blocks. The guide slide rod passes through the inner end of the support frame and the movable slide, and the two limiting blocks are symmetrically arranged at the left and right ends of the guide slide rod.

[0012] Furthermore, the elastic connection structure includes a fixing bolt and a compression spring. The fixing bolt passes through the limiting baffle and is threaded into the side end face of the support frame. The compression spring is disposed between the limiting baffle and the countersunk head of the fixing bolt.

[0013] Furthermore, the inner side of the limiting baffle is provided with an anti-slip pad.

[0014] Furthermore, the upper end face of the support frame is provided with two first limiting grooves, and the upper end face of the movable slide is provided with two second limiting grooves, with the two first limiting grooves and the two second limiting grooves arranged symmetrically front and back.

[0015] Furthermore, a movable slide plate is provided at the outer end of each of the movable carriages.

[0016] Compared with existing technologies, the offshore oil platform cabinet moving and transporting rack described in this utility model has the following advantages:

[0017] 1. The adjusting mechanism allows for precise adjustment of the distance between the carriage and the support frame via a handwheel and adjusting screw, adapting to different sizes of cabinets. This flexible adjustment function makes the transport rack widely applicable to various specifications of cabinets, improving the equipment's versatility. The handwheel makes operation simple and intuitive, allowing operators to complete adjustments without complicated tools, reducing operation time and improving work efficiency. The adjusting mechanism, through threaded transmission and bearing housing cooperation, ensures the stability of the moving carriage during adjustment, preventing loosening or displacement due to external interference or load vibration.

[0018] 2. The guiding structure, through the linear motion of the guide rod and the constraint of the limiting blocks, ensures that the moving carriage slides in a predetermined direction, avoiding deviation and errors. The limiting blocks, located at both ends of the guide rod, effectively prevent the carriage from detaching or engaging in non-linear motion during sliding, thereby improving the system's operational accuracy. The guide rod has a low-friction sliding surface, ensuring smooth and stable sliding of the carriage without jamming or vibration due to excessive friction. Under high loads, the guiding structure still provides stable guidance, ensuring the balance of heavy-duty cabinets during handling. The rigid support of the guide rod and the positioning effect of the limiting blocks enhance the stability of the carriage, ensuring that its sliding trajectory remains unchanged even under lateral forces or vibrations.

[0019] 3. The limit baffle, through contact with the control panel housing, accurately positions the control panel, preventing it from shifting or sliding during transport. Through the buffering effect of the elastic connection structure (compression spring and fixing bolts), the limit baffle absorbs some energy when the equipment is subjected to external impact, reducing the risk of damage to the control panel. The anti-slip pads on the limit baffle increase friction, effectively preventing the control panel from sliding due to platform swaying or vibration, thus ensuring the safety of equipment transport. The buffering characteristics of the elastic connection structure allow the limit baffle to adapt to the dynamic environment of offshore oil platforms (such as swaying and vibration caused by wind and waves), reducing hard impacts between the control panel and the baffle, and extending the service life of the equipment. The elastic compression spring absorbs impact force, preventing damage to the control panel or deformation of the limit baffle caused by rigid collisions. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] A type of offshore oil platform cabinet moving and handling rack, such as Figure 1As shown, it includes a support frame 101, two movable slides 201, two guide structures, two limiting baffles 400, two adjusting mechanisms, four moving components 500, and eight elastic connecting structures 410. The two movable slides 201 are symmetrically arranged on the left and right sides of the support frame 101, and the two guide structures are arranged side by side. The middle part of the support frame 101 is slidably engaged with the movable slides 201 through the two guide structures. Each movable slide 201 is connected to the side of the support frame 101 through an adjusting mechanism, which is used to adjust the distance between the movable slides 201 and the support frame 101.

[0032] Two limiting baffles 400 are symmetrically arranged on the front and rear end faces of the support frame 101. The bottom of each limiting baffle 400 is connected to the support frame 101 through four elastic connection structures 410. The four elastic connection structures 410 located on the same side are symmetrically arranged on the left and right sides. The limiting baffles 400 are used to position the outer end face of the cabinet shell. Two moving components 500 are correspondingly arranged at the bottom of each movable slide 201. The cross-section of both the support frame 101 and the movable slide 201 is C-shaped, and the openings of both the support frame 101 and the movable slide 201 face downwards. In this embodiment, the moving component 500 includes a fixed plate and two moving rollers. The two moving rollers are symmetrically arranged on the lower end face of the fixed plate, and the fixed plate is arranged on the lower end face of the movable slide 201.

[0033] The upper end face of the support frame 101 is provided with two first limiting grooves 102, and the upper end face of the movable slide 201 is provided with two second limiting grooves 202. The two first limiting grooves 102 and the second limiting grooves 202 are symmetrically arranged front and rear. A movable slide plate 600 is provided at the outer end of each movable slide 201.

[0034] like Figure 3 As shown, the adjustment mechanism includes a handwheel 803, an adjusting screw 802, and a bearing seat 801. The adjusting screw 802 passes through the movable slide 201 and is rotatably connected to the bearing seat 801. The bearing seat 801 is located inside the support frame 101. The adjusting screw 802 is threadedly connected to the movable slide 201, and the handwheel 803 is located at the outer end of the adjusting screw 802. The adjustment mechanism achieves precise adjustment of the distance between the slide and the support frame 101 through the handwheel 803 and the adjusting screw 802, adapting to different sizes of cabinets. The flexible adjustment function makes the transport rack widely applicable to various specifications of cabinets, improving the versatility of the equipment. The handwheel 803 makes operation simple and intuitive, allowing operators to complete the adjustment without complicated tools, reducing operation time and improving work efficiency. The adjustment mechanism, through threaded transmission and the cooperation of the bearing seat 801, ensures the stability of the movable slide 201 during adjustment, preventing it from loosening or shifting due to external interference or load vibration.

[0035] like Figure 2As shown, the guiding structure includes a guide slide rod 701 and two limiting blocks 702. The guide slide rod 701 passes through the inner ends of the support frame 101 and the movable carriage 201. The two limiting blocks 702 are symmetrically arranged at the left and right ends of the guide slide rod 701. The guiding structure ensures that the movable carriage 201 slides in a predetermined direction through the linear movement of the guide slide rod 701 and the constraint of the limiting blocks 702, avoiding deviation and errors. The limiting blocks 702, located at both ends of the guide slide rod 701, effectively prevent the carriage from detaching or moving nonlinearly during sliding, thereby improving the system's operating accuracy. The guide slide rod 701 has a low-friction sliding surface, allowing the carriage to slide smoothly and steadily without jamming or vibration due to excessive friction. Under high load conditions, the guiding structure still provides stable guidance, ensuring the balance of heavy-duty cabinets during handling. The guide structure improves the stability of the carriage through the rigid support of the guide slide rod 701 and the positioning function of the limit block 702, ensuring that the carriage's sliding trajectory does not deviate even when subjected to lateral external forces or vibrations.

[0036] like Figure 4 As shown, the elastic connection structure 410 includes a fixing bolt 411 and a compression spring 412. The fixing bolt 411 passes through the limiting baffle 400 and is threaded onto the side end face of the support frame 101. The compression spring 412 is positioned between the limiting baffle 400 and the countersunk head of the fixing bolt 411. An anti-slip pad 301 is provided on the inner side of the limiting baffle 400. Through contact with the cabinet housing, the limiting baffle 400 can accurately position the cabinet, preventing it from shifting or sliding during transport. Through the buffering effect of the elastic connection structure 410 (compression spring 412 and fixing bolt 411), the limiting baffle 400 can absorb some energy when the equipment is subjected to external impact, reducing the risk of damage to the cabinet. The anti-slip pad 301 of the limiting baffle 400 increases friction, effectively preventing the cabinet from sliding due to platform shaking or vibration, thereby ensuring the safety of equipment transport. The limit baffle 400, through the buffering characteristics of the elastic connection structure 410, can adapt to the dynamic environment on the offshore oil platform (such as swaying and vibration caused by wind and waves), reducing the hard impact between the panel and the baffle and extending the service life of the equipment. The elastic compression spring 412 can absorb the impact force and avoid damage to the panel or deformation of the limit baffle 400 caused by rigid collision.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
