Description

Technical Field

[0001] The invention relates to the technical field of handling equipment, in particular to an intermittent heavy object side-mounted track. Background Art

[0002] In offshore oil platforms, ships and other large-scale marine projects, the overall structure of the assembly platform is compact, and the equipment installation space is limited. The platform's assembly buckles are greatly affected by the arrival time of the equipment. If key equipment is not delivered, the upper layer cannot be constructed as scheduled, which seriously affects the project construction time. At this time, the equipment needs to be dragged from the side of the platform to the final position of the equipment inside the platform. Due to the narrow space between the upper and lower layers of the platform, large cranes and tools cannot be used for operation. For equipment weighing hundreds of tons, the traditional side installation process has the following defects:

[0003] Construction methods such as forced dragging and rolling bars are likely to cause damage to the platform deck and the equipment itself. The use of complex mechanical equipment for driving has limited equipment installation space. The friction caused by heavy objects requires the drive parts to provide super-large torque, which is costly and difficult to arrange.

[0004] The degree of automation is low and requires a large amount of manpower to operate;

[0005] Therefore, an intermittent heavy object side-mounted track is provided to solve the above problems. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides an intermittent heavy object side-mounted track, which solves the problem that the traditional side-mounted process is prone to damage to the platform deck and the equipment itself through construction methods such as forced dragging and rolling bars, and is driven by complex mechanical equipment. The equipment installation space is limited, and the friction caused by the heavy objects requires the driving parts to provide super-large torque, which is costly and difficult to arrange. In addition, the degree of automation is low, and a large amount of manpower is required to perform the operation.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: an intermittent heavy object side-mounted track, comprising a side-mounted track body and a hydraulic station, a tray assembly is slidably arranged on the top of the side-mounted track body, and a hydraulic travel assembly is installed at the bottom of the tray assembly;

[0008] The side-mounted track body includes a plurality of track assemblies, and the plurality of track assemblies are connected end to end to form a linear splicing;

[0009] The track assembly is provided with a travel guide, and a plurality of wedge-shaped protrusions are provided on the top of the travel guide;

[0010] The hydraulic travel assembly includes a travel hydraulic cylinder installed at the bottom of the tray assembly and a T-shaped travel push block fixedly installed at the output end of the travel hydraulic cylinder;

[0011] The hydraulic station provides hydraulic power output for the travel hydraulic cylinder;

[0012] One side of the wedge-shaped protrusion is a vertical surface, and the other side of the wedge-shaped protrusion is an inclined surface;

[0013] The T-shaped walking push block abuts against the vertical surface to push the tray assembly to move;

[0014] The T-shaped travel push block is retracted and moved toward the side close to the travel hydraulic cylinder through the inclined surface.

[0015] Preferably, the number of the side-mounted rail bodies is at least two, the number of the tray assemblies is at least four, the four tray assemblies are respectively placed on the top of the two side-mounted rail bodies, and heavy objects are placed on the top of the four tray assemblies.

[0017] The walking guide piece is fixedly welded on the upper surface of the bottom plate, and the walking guide piece is located between two groups of side square steel pipes.

[0018] Preferably, the wedge-shaped protrusions are integrally formed with the travel guide, and equidistant horizontal sliding portions are provided between the multiple groups of wedge-shaped protrusions. When in use, the pallet assembly is dragged by the travel hydraulic cylinder for intermittent movement, and a single movement distance is the length of a horizontal sliding portion.

[0019] Preferably, a mounting hole is provided on the outer side of the side square steel tube, and the mounting hole and the connecting piece are respectively located at both ends of the side square steel tube. The outer surface of the connecting piece is provided with the same connecting hole, and the connecting piece is installed by installing a track connecting pin inside the connecting hole and the mounting hole. Two adjacent sets of track assemblies are spliced ​​by installing the track connecting pin between the connecting piece and the mounting hole, so as to be quickly assembled to form a side-mounted track body for sliding heavy objects. In the case of inconvenience in carrying or low procurement budget, a small number of track assemblies can be used. During the movement of heavy objects, the track assembly that has passed through the rear end can be disassembled and quickly installed on the moving path of the front end, thereby realizing moving, disassembling and assembling at the same time, reducing the number of track assemblies carried, and reducing costs and equipment storage space.

[0020] Preferably, a gasket is provided on the top of the side square steel tube, and the gasket includes a PTFE gasket.

[0025] The pallet ear plates are slidably connected to the inner sides of the two sets of side square steel pipes, thereby limiting the position of the pallet assembly to prevent lateral deviation when it slides.

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The embodiment of the present application solves the problem that the traditional side-mounting process, through providing an intermittent heavy object side-mounting track, is prone to damage to the platform deck and the equipment itself through construction methods such as forced dragging and rolling bars. It uses complex mechanical equipment to drive, and the equipment installation space is limited. The friction caused by the heavy object requires the driving part to provide an extremely large torque, which is costly and difficult to arrange. In addition, the degree of automation is low, and a large amount of manpower is required to perform the operation.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] The embodiment of the invention discloses an intermittent heavy object side-mounted track.

[0043] According to the attached Figure 1-8 As shown, it includes a side-mounted track body 3, a tray assembly 1 is slidably arranged on the top of the side-mounted track body 3, and a hydraulic walking component assembly 2 is installed at the bottom of the tray assembly 1;

[0044] The side-mounted track body 3 includes a plurality of track assemblies 34, and the plurality of track assemblies 34 are connected end to end to form a linear splicing;

[0045] The track assembly 34 is provided with a travel guide 343 , and a plurality of wedge-shaped protrusions 3432 are provided on the top of the travel guide 343 ;

[0046] The hydraulic travel component assembly 2 includes a travel hydraulic cylinder 21 installed at the bottom of the tray assembly 1 and a T-shaped travel push block 22 fixedly installed at the output end of the travel hydraulic cylinder 21;

[0047] One side of the wedge-shaped protrusion 3432 is a vertical surface, and the other side of the wedge-shaped protrusion 3432 is an inclined surface;

[0048] The T-shaped walking push block 22 abuts against the vertical surface to push the pallet assembly 1 to move, and the heavy objects are placed on the upper surface of the multiple pallet top plates 11. The output end of the walking hydraulic cylinder 21 extends outward, and at this time, the T-shaped walking push block 22 abuts against the vertical surface, thereby forming a reverse thrust, so that the multiple pallet top plates 11 slide forward with the heavy objects;

[0049] The T-shaped travel push block 22 shrinks and moves toward the side close to the travel hydraulic cylinder 21 through the inclined surface.

[0050] It also includes a hydraulic station 5, which provides hydraulic power output for the travel hydraulic cylinder 21.

[0051] There are at least two sets of side-mounted rail bodies 3 , and at least four sets of tray assemblies 1 . The four sets of tray assemblies 1 are respectively placed on the top of the two sets of side-mounted rail bodies 3 , and heavy objects 6 are placed on the top of the four sets of tray assemblies 1 .

[0052] The track assembly 34 includes a base plate 344, side square steel tubes 342 and two groups of connecting parts 341; the side square steel tubes 342 are fixedly welded on both sides of the top of the base plate 344; the two groups of connecting parts 341 are respectively fixedly welded on the outer sides of the opposite ends of the two groups of side square steel tubes 342, and the walking guide 343 is fixedly welded on the upper surface of the base plate 344, and the walking guide 343 is located between the two groups of side square steel tubes 342.

[0053] The wedge-shaped protrusions 3432 are integrally formed with the travel guide 343 , and equidistant horizontal slides 3433 are provided between the multiple groups of wedge-shaped protrusions 3432 . When in use, the pallet assembly 1 is dragged by the travel hydraulic cylinder 21 for intermittent movement, and a single movement distance is the length of a horizontal slide 3433 .

[0054] A mounting hole 345 is provided on the outer side of the side square steel tube 342, and the mounting hole 345 and the connecting piece 341 are respectively located at the two ends of the side square steel tube 342. The outer surface of the connecting piece 341 is provided with the same connecting hole, and the connecting piece 341 is installed by installing the track connecting pin 4 inside the connecting hole and the mounting hole 345. The two adjacent groups of track assemblies 34 are spliced ​​by installing the track connecting pin 4 between the connecting piece 341 and the mounting hole 345, so as to be quickly assembled to form a side-mounted track body 3 for sliding heavy objects. In the case of inconvenience in carrying or low procurement budget, a small number of track assemblies 34 can be used. During the movement of heavy objects, the track assembly 34 that has passed through the rear end is disassembled and quickly installed on the moving path of the front end, thereby realizing moving, disassembling and assembling at the same time, reducing the number of track assemblies 34 carried, reducing costs and equipment storage space.

[0055] A gasket is provided on the top of the side square steel tube 342, and the gasket includes a PTFE gasket 31. A plurality of strip grooves are provided on the upper surface of the PTFE gasket 31, and a PTFE strip 32 is placed inside the strip groove. A screw 33 is installed on the top of the PTFE strip 32. The screw 33 passes through the PTFE gasket 31 and the PTFE strip 32, and the screw 33 is threadedly connected in the side square steel tube 342. When in use, the tray assembly 1 slides relative to the upper surface of the PTFE gasket 31. Due to the characteristics of its material, the PTFE gasket 31 can reduce the friction generated when the tray assembly 1 moves, thereby reducing the hydraulic thrust required for the movement of the equipment.

[0056] The pallet assembly 1 includes a pallet top plate 11, a pallet ear plate 12 and a pallet limit strip 13; the pallet limit strip 13 is integrally formed on both sides of the bottom of the pallet top plate 11; the pallet ear plate 12 is fixedly welded to the bottom of the pallet top plate 11, and the pallet ear plate 12 is located between the two sets of pallet limit strips 13.

[0057] A connecting ear plate 23 is fixedly welded to one end of the travel hydraulic cylinder 21 away from the T-shaped travel push block 22, and the connecting ear plate 23 is movably hinged to the pallet ear plate 12. When in use, when the output end of the travel hydraulic cylinder 21 pulls the T-shaped travel push block 22 to move forward, the T-shaped travel push block 22 slides upward along the inclined surface. During this process, the connecting ear plate 23 rotates in the pallet ear plate 12, so that the T-shaped travel push block 22 can climb over the wedge-shaped protrusion 3432.

[0058] The pallet ear plate 12 is slidably connected to the inner sides of the two sets of side square steel tubes 342, thereby limiting the position of the pallet assembly 1 to prevent it from lateral deviation when sliding.

[0059] Working principle: When the intermittent heavy object side-mounted track is used, the track assemblies 34 are connected and laid on the deck in sequence, and two adjacent sets of track assemblies 34 are spliced ​​by installing the track connecting pins 4 between the connecting piece 341 and the mounting hole 345, so as to quickly assemble and form the side-mounted track body 3 for the heavy object to slide;

[0060] Then the tray assembly 1 is placed on the top of the track assembly 34. At this time, the lower surface of the tray top plate 11 is in contact with the PTFE gasket 31. The PTFE gasket 31 reduces the friction resistance during sliding. At the same time, the two sets of tray limit strips 13 are located on the inner sides of the two sets of side square steel pipes 342, thereby limiting the tray assembly 1 to prevent it from lateral deviation during sliding.

[0061] Then, by adjusting the placement position of the hydraulic travel assembly 2 at the bottom of the pallet assembly 1, ensure that the front side of the T-shaped travel push block 22 abuts against the vertical surface of the wedge-shaped protrusion 3432, and then connect the multiple travel hydraulic cylinders 21 to the hydraulic station 5 through the hydraulic oil pipe, and then place the heavy objects on the upper surface of the multiple pallet top plates 11 to complete the assembly preparation work before moving;

[0062] Hydraulic oil is injected into the multiple travel hydraulic cylinders 21 through the hydraulic station 5. At this time, the output end of the travel hydraulic cylinder 21 extends outward. At this time, the T-shaped travel push block 22 is against the vertical surface, thereby forming a reverse thrust, so that the multiple pallet top plates 11 carrying the heavy objects slide forward. The sliding distance is the length of a horizontal sliding portion 3433. Then the hydraulic station 5 draws back the hydraulic oil to make the output end of the travel hydraulic cylinder 21 shrink. At this time, under the action of the gravity of the heavy objects, static friction is formed between the pallet top plate 11 and the PTFE gasket 31, so that the pallet top plate 11 remains stationary. The output end of the travel hydraulic cylinder 21 pulls the T-shaped travel push block 22 forward. At this time, the T-shaped travel push block 22 slides upward along the inclined surface. During this process, the connecting ear plate 23 rotates in the pallet ear plate 12. When the T-shaped travel push block 22 slides to the top of the inclined surface, it will fall downward if it continues to slide forward and enter the vertical surface position of the next wedge-shaped protrusion 3432. At this time, one stage of movement is completed;

[0063] Then repeat the above steps, so that the travel hydraulic cylinder 21 pushes the tray assembly 1 and the heavy object to slide intermittently on the top of the track assembly 34, and finally moves the heavy object to the target position. The entire moving trajectory is as follows: Figure 8 As shown, a plurality of continuous wedge-shaped protrusions 3432 and horizontal sliding portions 3433 are arranged alternately to form a continuous wave path, and the T-type walking push block 22 moves along the wave path during the whole process. Figure A shows the initial state, at which time the T-type walking push block 22 contacts the vertical surface of the first group of wedge-shaped protrusions 3432; Figure B shows that after the output end of the walking hydraulic cylinder 21 is extended, it drives the pallet assembly 1 to complete a displacement; at this time, the T-type walking push block 22 is in the trough, and Figure C shows that the output end of the walking hydraulic cylinder 21 contracts, so that the T-type walking push block 22 moves along the horizontal sliding portion 3433, from the vertical surface of the first wedge-shaped protrusion 3432 to the starting point of the inclined surface of the next wedge-shaped protrusion 3432; Figure D shows that the output end of the walking hydraulic cylinder 21 continues to contract, driving the T-type walking push block 22 to slide along the inclined surface until it is disengaged, at which time the T-type walking push block 22 passes the wave crest and enters the horizontal surface of the next wedge-shaped protrusion 3432, waiting for a second movement.

[0064] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
