Description

Technical Field

[0001] The invention belongs to the technical field of transportation devices, and relates to material transportation, in particular to a material transportation device for construction of a pumped storage power station. Background Art

[0002] With the adjustment of global energy structure and the emphasis on renewable energy, pumped storage power stations, as an important energy storage facility, are increasing in scale and quantity. During the construction of pumped storage power stations, the transportation of construction materials is a critical and complex task, which directly affects the progress, quality and cost of the project. Pumped storage power stations are usually built in mountainous areas with complex terrain, large terrain undulations and inconvenient transportation. Traditional material transportation methods generally include large transport vehicles, rail vehicles, and lifting devices, but for short-distance material transportation, two-wheeled carts are still the first choice for staff.

[0003] In the prior art, when a two-wheeled cart is in use, it is necessary to apply not only a horizontal force to the two-wheeled cart but also a vertical force to the cargo box to ensure that the cargo box is level and the materials inside will not fall over. This consumes a lot of physical strength of the workers when the two-wheeled cart is going uphill or downhill, thereby reducing work efficiency and the transportation efficiency of materials. For this reason, a material transportation device for the construction of a pumped-storage power station is designed. Summary of the invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a material transportation device for the construction of a pumped-storage power station. The technical problem to be solved by the invention is: when transporting materials over short distances, when workers use two-wheeled carts to transport materials, the work efficiency is low and it is very physically demanding on uphill and downhill sections.

[0005] The purpose of the present invention can be achieved by the following technical solutions: The cam is an angular channel formed between a pair of camshafts and a pair of camshafts, and the camshafts are connected to a pair of camshafts which are connected by a pair of locking plates.

[0006] The working principle of the present invention is: the second round rod drives the connecting rod and other components of the switching mechanism to slide back and forth along the two connecting blocks, so that the switching mechanism can drive the two wheels or universal wheels to rise and fall respectively, thereby reducing the labor intensity of the staff, reducing the physical exertion of the staff, and improving the work efficiency.

[0007] The auxiliary support mechanism includes two vertical rods fixedly connected to both sides of the bottom of the outer side of the box body, the middle part and the bottom of the two vertical rods are rotatably connected to a rotating rod, the other end of the four rotating rods is rotatably connected to the same T-shaped plate, and the two ends of the bottom of the T-shaped plate are rotatably connected to universal wheels, the bottom of the outer wall of the box body is located at one end of the push handle and fixedly connected to two third fixed blocks, the same screw rod is rotatably connected between the two third fixed blocks, and a moving block is screwed on the circumferential surface of the screw rod, and a screw rod nut matching the screw rod is fixedly sleeved in the middle of the moving block, both ends of the moving block are rotatably connected to push rods, and the other ends of the two push rods are rotatably connected to the middle of the adjacent rotating rods, the auxiliary support mechanism also includes a second sleeve fixedly connected to one end of the screw rod close to the switching mechanism, and the third fixed block on this side is provided with a The circumferential wall of the second sleeve is fixedly connected with a plurality of fourth strip blocks at equal distances near the screw rod, and the fourth strip block is matched with the third strip block, the circumferential outer wall of the second sleeve is fixedly connected with a first fixing ring near one end of the switching mechanism, the middle part of the circumferential outer wall of the second sleeve is also fixedly sleeved with a second fixing ring, and the outer wall of the second sleeve is located between the second fixing ring and the first fixing ring and is fixedly connected with two limit strips, and the outer wall of the second sleeve is located at the two limit strips and is slidably sleeved with a sliding snap ring, and a groove matched with the limit strip is opened on the circumferential inner wall of the sliding snap ring, and the outer wall of the second sleeve is located between the second fixing ring and the sliding snap ring and a spring is sleeved, and the sliding snap ring is matched with the pressure rod, and the outer bottom of the outer side of the box body is fixedly connected with a snap ring near the sliding snap ring, and the snap ring is matched with the sliding snap ring.

[0008] By adopting the above structure and setting up the auxiliary supporting mechanism, the rotation of the screw rod drives the moving block and the push rod to move, and then the rotating rod makes the T-shaped plate and the universal wheel rise and fall. At the same time, the setting of the four rotating rods makes it possible for the universal wheel to always be vertical when the T-shaped plate is raised or lowered, so that when the box is going uphill or downhill, the user can control the box more conveniently and easily through the two added universal wheels, thereby reducing the physical exertion of the staff. When the motor drives the wheel to rotate, the auxiliary supporting mechanism cooperates with the latch gear, so that the screw rod will not rotate, thereby ensuring the position stability of the universal wheel.

With the above structure, the second rotating rod is driven to rotate by the connecting rod, so that the second gear rotates with the first gear, and then the two wheels start to rotate.

[0014] With the above structure, the staff can control the switching mechanism to be close to one side of the wheel or the auxiliary support mechanism by rotating the crank forward and reverse, so as to control the wheel to rotate or the universal wheel to rise and fall.

[0015] Compared with the prior art, the pumped storage power station construction material transportation device of the present invention has the following advantages: 1. In the present invention, due to the use of technical means such as a switching mechanism, an auxiliary supporting mechanism, a second round rod and a fixed plate, when the box moves on the slope, the switching mechanism drives the two universal wheels to rise and fall, so that the universal wheels are in contact with the slope, thereby improving the stability of the box and avoiding the staff from wasting physical energy on controlling the balance of the box. This effectively solves the problem of the laboriousness of the two-wheeled cart proposed in the background technology, thereby achieving significant reduction in the physical energy consumption of the staff, improving the transportation efficiency and safety when transporting materials on the slope, and ensuring that the box always maintains a stable and balanced state under complex slope terrain. This not only solves the problem that the traditional two-wheeled cart is easy to tip over and requires manual effort to maintain balance, but also makes the material transportation process smoother and more efficient, reduces the risks of material spillage, collision damage, etc. caused by shaking or imbalance of the box, and improves the reliability and convenience of the entire material transportation link.

By rotating the crank forward and reversely, the second round rod 701 moves with the rotating block 405, the gear sleeve 404 and the connecting rod 402, thereby realizing separate driving, the auxiliary support mechanism 5 or the wheel 3, and one end of the bottom of the outer side of the box body 1 close to the push handle 2 is fixedly connected to a fixed plate 702, and the second round rod 701 is provided with a threaded groove 703 near the fixed plate 702, and a screw nut matching the threaded groove 703 is fixedly sleeved at the bottom of the fixed plate 702.

[0028] The working principle of the present invention is as follows: when in use, the user pushes or pulls the box body 1 through the push handle 2, and drives the gear sleeve 404 to rotate through the third gear 601, so that the connecting rod 402 rotates. When the second bar block 403 is close to the first bar block 315, it will drive the second rotating rod 312 and the second gear 313 to rotate, thereby causing the first gear 311 to rotate with the third bevel gear 309. The first bevel gear 303, the bevel spur gear 305, the second fixed block 306 and the third bevel gear 309 form a differential structure, so that the motor 6 can drive the two wheels 3 to rotate synchronously, and when one wheel 3 does not rotate, the other wheel 3 can rotate, which is convenient for the steering of the box body 1, thereby reducing the labor intensity and improving the work efficiency. When used uphill or downhill, in order to ensure the stability of the box body 1 on the slope, the crank at one end of the second round rod 701 is rotated at this time, so that the second round rod 701 rotates with 4 and 5. The second strip block 403 is separated from the first strip block 315, and the third strip block 408 is engaged with the fourth strip block 510. At the same time, under the action of the four pressure rods 407, the sliding snap ring 515 compresses the spring 516, and the sliding snap ring 515 is separated from the snap teeth 514. At this time, the screw rod 506 can rotate by itself. Due to the long length of the gear sleeve 404, it is still engaged with the third gear 601. The motor 6 is started to rotate, so that the connecting rod 402 rotates with the screw rod 506, so that the movement of the moving block 504 is controlled. Under the action of the push rod 503 and the rotating rod 502, the two universal wheels 508 are further controlled to rise or fall. When on the slope, through the support of the two universal wheels 508 and the cooperation of the two wheels 3, it is convenient to maintain the stability of the box body 1, further reduce the physical consumption of the staff, and improve the work efficiency.

[0029] In summary, in the present invention, by switching the switching mechanism 4, the third gear 601 can drive the rotation of the two wheels 3. At the same time, under the principle of the differential, it is convenient for the staff to turn and reduce the physical exertion of manual labor. At the same time, with the setting of the auxiliary support mechanism 5, the box 1 is more stable when going uphill or downhill through the addition of two universal wheels 508, and the physical exertion consumed by the staff for controlling the box 1 is reduced.
