Description

Technical Field

[0001] The present application relates to the technical field of hoisting equipment, and in particular to a road construction material transportation device. Background Art

[0002] During the construction process, it is necessary to lift and transport building materials according to construction needs. Among them, pipes are a more commonly used building material. Pipes can not only transport fluid media such as water, gas, oil, and heat, but also serve as supporting materials for building structures.

[0003] Since the pipes have a certain weight and need to be lifted to a specified height when used, workers are required to manually bundle the pipes and place them on a hanging platform before hoisting and transportation of the pipes to ensure the stability of the pipes during the hoisting and transportation process.

[0004] However, after the pipes are hoisted to the specified height, if the workers need to take the pipes, they need to loosen the bundles of the pipes. At this time, the pipes will be in a loose state. If the hanging platform in the air is affected by the wind and shakes, the pipes on the hanging platform will be at risk of falling. If guardrails are installed around the hanging platform, although the falling of the pipes can be avoided, the workers need to take the pipes in the guardrail from above the guardrail. If the amount of pipes placed in the guardrail is large, the guardrail needs to have a certain height. If the height of the guardrail is too large, it will be inconvenient for the workers to take the pipes at the bottom of the guardrail, so it needs to be improved. Summary of the invention

[0037] The following is combined with Figure 1-9 This application is described in further detail.

[0038] The present application embodiment discloses a road construction material transportation device. Figure 1As shown, a road construction material transportation device includes a base 1, rollers 11 are installed at the four corners of the lower surface of the base 1, four hydraulic cylinders 12 are installed on the upper surface of the base 1, the piston rods of the four hydraulic cylinders 12 extend in the vertical direction and are installed with the same lifting seat 13; a lifting unit 2 is provided on the lifting seat 13, and the lifting unit 2 includes a motor 21 installed on the lifting seat 13, the output shaft of the motor 21 extends in the horizontal direction and is coaxially connected with a roller 22, the roller 22 rotates around its own axis and is connected to the lifting seat 13, and the roller 22 is connected to the material box 3 through a plurality of suspension ropes 23, the pipe can be placed in the material box 3, the hydraulic cylinder 12 can drive the lifting seat 13 to rise, and the motor 21 can drive the roller 22 to rotate to make the roller 22 reel or unreel the suspension rope 23, so that the material box 3 can rise and fall, so as to load and take the pipe.

[0039] It is worth mentioning that during the feeding process of the pipe, the material box 3 will be placed on the upper surface of the base 1 to ensure the stability of the material box 3; in the present embodiment, there are four lifting ropes 23, and the four lifting ropes 23 are connected to the upper surface of the material box 3 to improve the stability of the material box 3; the left and right side walls of the material box 3 are connected to the upper surface of the base 1 by pull ropes 14. When the material box 3 rises to the highest point, the pull ropes 14 will be in a taut state, so that the material box 3 is not easy to shake in the air.

[0040] like Figure 2 As shown, partitions 31 are installed on the inner walls of the left and right sides of the material box 3. The partitions 31 are arranged alternately on the left and right sides in the material box 3, and the projections of the partitions 31 on the vertical plane are inclined. Multiple partitions 31 together form a serpentine channel 32 inside the material box 3; the front end of the material box 3 is open, and the open end of the material box 3 is located in the extension direction of the serpentine channel 32, so that workers can insert the pipe horizontally into the serpentine channel 32.

[0041] Compared with the prior art, the present application can load a large number of pipes, and the pipes will be arranged in a serpentine shape in the serpentine channel 32 to avoid the pipes from being scattered. The pipes can be taken from top to bottom in sequence, and the present application does not require the installation of guardrails, and workers do not need to bend over to take the pipes in the guardrails, thereby facilitating the taking of the pipes.

[0042] like Figure 3 and Figure 4As shown, the open end of the material box 3 is provided with a plurality of telescopic units 4 corresponding to the partitions 31, and the telescopic units 4 can be telescoped in the vertical direction; the telescopic units 4 include an upper baffle 41 and a lower baffle 42 arranged at an interval, the lower surface of the upper baffle 41 and the upper surface of the lower baffle 42 are connected by folding blades 43, and the left and right ends of the upper baffle 41 are both installed with counterweight columns 44, the lower baffle 42 is installed on the material box 3, and the left and right ends of the lower baffle 42 are both installed with fixed cylinders 45, and the counterweight columns 44 are slidably embedded in the fixed cylinders 45 in the vertical direction. By sliding the counterweight columns 44 in the fixed cylinders 45, the vertical distance between the upper baffle 41 and the lower baffle 42 can be adjusted, so that the height of the folding blades 43 is changed.

[0043] like Figure 5 and Figure 6 As shown, the interior of the partition 31 is hollow and provided with a fluid cavity 311. The upper surface of the partition 31 is provided with a plurality of slide grooves 312 arranged in sequence along the inclination direction of the partition 31. The slide grooves 312 are connected to the fluid cavity 311, and an elastic unit 5 is provided in the slide grooves 312. The elastic unit 5 includes a support seat 51 slidably embedded in the slide grooves 312. The upper end of the support seat 51 is provided with a downward pressure surface 511, and the lower end of the support seat 51 is connected to the partition 31 through a first spring 52. In this embodiment, one end of the first spring 52 is fixedly connected to the support seat 51, and the other end of the first spring 52 is fixedly connected to the cavity wall of the fluid cavity 311. When the first spring 52 is in a natural state, the upper end of the support seat 51 will protrude out of the slide groove 312, and the downward pressure surface 511 will be located above the partition 31.

[0044] like Figures 4 to 6 As shown, the fixed cylinder 45 is connected to the fluid cavity 311 through the connecting tube 46, and the connecting tube 46 is a hard tube. The fluid cavity 311, the connecting tube 46 and the fixed cylinder 45 are all filled with fluid. Before the pipe is loaded, all the first springs 52 will be in a natural state, at which time the support seat 51 will be in the highest state, the fluid in the fluid cavity 311 will be in the most state, the fluid in the fixed cylinder 45 will be in the least state, the counterweight column 44 and the upper baffle 41 will be in the lowest state, and the telescopic unit 4 will be in the shortest state. At this time, the telescopic unit 4 will be lower than the lowest point on the upper surface of the partition 31, so that the telescopic unit 4 will not affect the horizontal insertion of the pipe into the serpentine channel 32, so as to facilitate the loading of the pipe.

[0045] After loading, the pipe will be pressed against the lower pressure surface 511, so that the support seat 51 sinks into the slide groove 312, and the support seat 51 will press the fluid in the fluid cavity 311 into the fixed cylinder 45, so that the upper baffle 41 rises, and the folding blades 43 will gradually unfold and only block part of the pipe that has been loaded into the serpentine channel 32, while the subsequent pipes can continue to be inserted horizontally into the serpentine channel 32.

[0046] A first guide surface 512 is provided at the upper end of the support seat 51, and the first guide surface 512 is inclined. During the downward rolling process, the pipe can roll onto the downward pressing surface 511 through the first guide surface 512, so that the pipe can be arranged in a serpentine shape in the serpentine channel 32, and it is convenient for the pipe to press the support seat 51 downward and sink it into the slide groove 312.

[0047] When the pipe loading is completed, all the support seats 51 will be pressed down and sunk into the slide groove 312, the telescopic unit 4 will be in the longest state, and the telescopic unit 4 will contact all the end faces of the pipes on the partition 31, so that the pipes in the serpentine channel 32 cannot slide out horizontally from the open end of the material box 3, so as to improve the stability of the pipes during the lifting process; in addition, at this time, the vertical distance between the telescopic unit 4 located on the uppermost side and the top wall of the material box 3 is equal to the diameter of the pipe, so that the pipes at the highest point of the uppermost partition 31 can be taken out from the inside of the material box 3 only when they rise to the highest point inside the material box 3, so as to avoid the pipes on the uppermost partition 31 from falling out of the open end of the material box 3 due to shaking during the lifting process; at this time, the vertical distance between the remaining telescopic units 4 and the adjacent partitions 31 above them will be less than the diameter of the pipe, so as to avoid the pipes on the remaining partitions 31 from falling out of the open end of the material box 3 due to shaking during the lifting process.

[0048] It is worth noting that when the telescopic unit 4 is in its longest state, the telescopic unit 4 can only block the middle and lower parts of the end face of the pipe at the highest point of the partition 31, so that the worker's hand can be inserted into the upper part of the pipe and lift the pipe, so that the worker can take the pipe out of the serpentine channel 32.

[0049] The cross-sectional area of ​​the chute 312 at the highest point of the partition 31 is larger than the cross-sectional areas of the other chute 312. During the process of taking the pipe, when the pipe at the highest point of the partition 31 is taken, the support seat 51 below the pipe will rise and reset under the action of the first spring 52, and the counterweight column 44 will descend in the fixed cylinder 45 due to its own gravity. Since the cross-sectional area of ​​the chute 312 where the support seat 51 is located is larger, more fluid in the fixed cylinder 45 is sucked into the fluid cavity 311. At this time, the upper baffle 41 will descend a greater distance, so that the upper baffle 41 is separated from the pipe end face adjacent to the taken pipe, so that the worker The next pipe can be pulled out horizontally; when the subsequent pipes on the partition 31 are taken, due to the smaller cross-sectional area of ​​the remaining slide grooves 312, less fluid in the fixed cylinder 45 is sucked into the fluid cavity 311, and the upper baffle 41 will drop a smaller distance at this time, so that the upper baffle 41 is separated from the pipe end face adjacent to the taken pipe; that is, whenever a group of elastic units 5 returns to the natural state, the telescopic unit 4 will become shorter and separate from the pipe end face on the elastic unit 5 adjacent to and located obliquely below the elastic unit 5, so that most of the pipes on the partition 31 can be taken horizontally for use, thereby facilitating the taking of the pipes.

[0050] It is worth noting that workers can only extract one pipe horizontally at a time, and the remaining pipes are still blocked by the telescopic unit 4. Therefore, even if the material box 3 shakes slightly in the air due to wind, the pipes in the material box 3 can still remain stable, thereby improving the stability of the pipes during the lifting process.

[0051] A plurality of top posts 313 corresponding to the support seat 51 are installed in the fluid cavity 311. When the pipe completely presses the support seat 51 into the slide groove 312, the top posts 313 will prevent the support seat 51 from further entering the slide groove 312. The support seat 51 is connected to the partition 31 through a traction rope 314. One end of the traction rope 314 is fixedly connected to the support seat 51, and the other end of the traction rope 314 is fixedly connected to the cavity wall of the fluid cavity 311. When the first guide surface 512 moves out of the slide groove 312, the traction rope 314 will be in a taut state and prevent the support seat 51 from further sliding out of the slide groove 312. The traction rope 314 and the top posts 313 cooperate with each other to limit the movement trajectory of the support seat 51, so that the inflow and outflow of the fluid in the fixed cylinder 45 remains stable, reducing the flow error of the fluid, so as to ensure the blocking effect of the telescopic unit 4 on the pipe.

[0052] like Figures 7 to 9 As shown, a plurality of upper clamping columns 33 are slidably penetrated in the horizontal direction on the material box 3, and the upper clamping columns 33 correspond to the partition 31 one by one, and the upper clamping columns 33 are located at the high end of the partition 31; a second guide surface 331 inclined downward is provided on the upper clamping column 33, and the upper clamping column 33 is connected to the lower clamping plate 36 through a connecting column 34, and the connecting column 34 is connected to the material box 3 through a second spring 35, one end of the second spring 35 is fixedly connected to the connecting column 34, and the other end of the second spring 35 is fixedly connected to the material box 3; a third guide surface 361 inclined downward is provided on the lower clamping plate 36, and a clamping groove 411 for horizontal insertion of the lower clamping plate 36 is provided on the upper baffle 41.

[0053] When the second spring 35 is in a natural state, one end of the upper clamping column 33 will extend into the material box 3 and be used to block the pipe at the high end of the partition 31 from rising, so as to prevent the pipe from falling out of the open end of the material box 3 due to shaking during the lifting process; at this time, the lower clamping plate 36 will be inserted into the clamping groove 411 of the telescopic unit 4 in the longest state, so that the upper baffle 41 is limited and fixed; therefore, even if multiple pipes on the partition 31 are temporarily detached from the support seat 51 due to shaking, since the upper baffle 41 is fixed, the support seat 51 will also be stationary, and the telescopic unit 4 will not become shorter and detached from the pipe on the partition 31, thereby improving the stability of the pipe during the lifting process.

[0054] During the process of taking out the pipe, the pipe at the highest point of the partition 31 can push the upper clamping column 33 to disengage from the inner side of the material box 3 through the second guide surface 331, so that the upper clamping column 33 no longer blocks the partition 31 from being taken out of the material box 3. At the same time, the upper clamping column 33 will drive the lower clamping plate 36 to disengage from the clamping slot 411 through the connecting column 34, so that the telescopic unit 4 will no longer block the subsequent pipe to be taken out; during the process of loading the pipe, the upper baffle 41 will gradually rise and push the lower clamping plate 36 to slide horizontally through the third guide surface 361, so that the slot rises to correspond to the lower clamping plate 36. At this time, the second spring 35 will return to its natural state and prompt the lower clamping plate 36 to be clamped in the slot, so that the upper baffle 41 is limited and fixed to ensure the stability of the pipe during the lifting process.

[0055] The implementation principle of a road construction material transportation device in an embodiment of the present application is as follows: during the loading process of pipes, the open end of the material box 3 will be exposed, and workers can insert the pipes horizontally into the serpentine channel 32 one by one, and the pipes will be arranged in a serpentine shape in the serpentine channel 32 to avoid the pipes from being scattered; after loading, the pipes will be pressed against the lower pressure surface 511 of the support seat 51, so that the support seat 51 sinks into the slide groove 312, and the support seat 51 will press the fluid in the fluid cavity 311 into the fixed cylinder 45, so that the upper baffle 41 rises, and the folding blades 43 will gradually unfold and only block part of the pipes that have been loaded into the serpentine channel 32, and subsequent pipes can continue to be inserted horizontally into the serpentine channel 32.

[0056] When the pipe loading is completed, all the support seats 51 will be pressed down and sunk into the slide groove 312, the telescopic unit 4 will be in the longest state, and the telescopic unit 4 will contact all the pipe end faces on the partition 31, so that the pipe in the serpentine channel 32 cannot slide out horizontally from the open end of the material box 3, so as to improve the stability of the pipe during the lifting process; in addition, at this time, the vertical distance between the telescopic unit 4 located at the uppermost side and the top wall of the material box 3 is equal to the diameter of the pipe, so that the pipe at the highest point of the uppermost partition 31 can be taken out from the inside of the material box 3 only when it rises to the highest point inside the material box 3, so as to avoid the uppermost partition The pipes on 31 may fall out of the open end of the material box 3 due to shaking during the lifting process; at this time, the vertical distance between the remaining telescopic units 4 and the adjacent partitions 31 above them will be smaller than the diameter of the pipe, so as to prevent the pipes on the remaining partitions 31 from falling out of the open end of the material box 3 due to shaking during the lifting process; moreover, the upper baffle 41 will be limited and fixed by the lower clamping plate 36 after rising to the highest state, so even if multiple pipes on the partition 31 are temporarily detached from the support seat 51 due to shaking, the telescopic unit 4 will not shorten the pipes detached from the partition 31, thereby improving the stability of the pipes during the lifting process.

[0057] During the process of taking the pipe, the pipe at the highest point of the partition 31 can push the upper clamping column 33 to be separated from the inner side of the material box 3 through the second guide surface 331, so that the upper clamping column 33 no longer blocks the partition 31 from being taken out horizontally from the material box 3, and the support seat 51 below the pipe will rise and reset under the action of the first spring 52, and the counterweight column 44 will descend in the fixed cylinder 45 due to its own gravity. Since the cross-sectional area of ​​the slide groove 312 where the support seat 51 is located is large, more fluid in the fixed cylinder 45 is sucked into the fluid cavity 311. At this time, the upper baffle 41 will descend a large distance, so that the upper baffle 41 is separated from the pipe end face adjacent to the pipe to be taken. , so that the worker can pull out the next pipe horizontally; when the subsequent pipes on the partition 31 are taken, due to the smaller cross-sectional area of ​​the remaining slide grooves 312, less fluid in the fixed cylinder 45 is sucked into the fluid cavity 311, and at this time the upper baffle 41 will drop a smaller distance, so that the upper baffle 41 is separated from the pipe end face adjacent to the taken pipe; that is, whenever a group of elastic units 5 returns to the natural state, the telescopic unit 4 will become shorter and separate from the pipe end face on the elastic unit 5 adjacent to and obliquely below the elastic unit 5, so that most of the pipes on the partition 31 can be taken horizontally for use, thereby facilitating the taking of the pipes.

[0058] To sum up, when the pipe at the highest point on the partition 31 is taken, the telescopic unit 4 will no longer block the pipes adjacent to the pipe, while the remaining pipes are still blocked by the telescopic unit 4, so that subsequent pipes can be taken horizontally one by one by workers, which facilitates the taking of the pipes and improves the stability of the pipes during the lifting process.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
