Description

Technical Field

[0001] This utility model relates to the field of pressure steel pipe transportation technology, specifically a pressure steel pipe transportation vehicle that can reduce chassis height. Background Technology

[0002] Pumped storage power stations are important peak-shaving, valley-filling, and energy storage facilities in the power system. Their construction is crucial for improving the stability of the power system and promoting the consumption of renewable energy. As a key component of the water conveyance system of pumped storage power stations, pressure steel pipes bear the heavy responsibility of conveying high-pressure water. Their transportation directly affects the progress and quality of the power station construction. When transporting pressure steel pipes by transport vehicles, due to the cylindrical shape of the pressure steel pipes, insufficient positioning on the transport vehicle can easily cause them to roll.

[0003] To address the aforementioned deficiencies, existing technology (Chinese Patent Publication No. CN203345651U, Publication Date 2013-12-18) provides a transport vehicle for transporting large steel pipes. The first limiting block is in the shape of a right-angled trapezoid, with the top width of the first limiting block being smaller than the bottom width. The second limiting block is also in the shape of a right-angled trapezoid, with the top width of the second limiting block being smaller than the bottom width. The first limiting block has a first inclined surface facing the second limiting block, and the second limiting block has a second inclined surface facing the first limiting block.

[0004] The above solution uses two symmetrically arranged trapezoidal limiting blocks to limit and fix the steel pipe. However, since the outer side of the steel pipe is circular, the contact surface with the limiting block is small, which makes it easy for the pipe to move during transportation. In addition, the chassis height of the transport vehicle is fixed. When encountering weight and height restrictions such as bridges and culverts during transportation, the large diameter and height of the pressure steel pipe, combined with the transport vehicle, can easily exceed the height limit, making it inconvenient to lower the chassis height. Utility Model Content

[0005] The purpose of this utility model is to provide a pressure steel pipe transport vehicle that can reduce the chassis height, so as to solve the problems mentioned in the background art that the existing pressure steel pipe transport vehicles are not convenient to reduce the chassis height when encountering height restriction facilities during transportation, and have poor stability when fixing the steel pipes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressure steel pipe transport vehicle that can reduce chassis height, including a frame, the frame being used for later connection with a truck, wheels being equally spaced on the front and rear sides of the frame, a carrier plate being provided on the top of the frame, limit plates being symmetrically provided on the top of the carrier plate, a pressure steel pipe body being mounted on the limit plate, and reinforcing ribs being equally spaced on the outer side of the pressure steel pipe body;

[0007] A height adjustment structure is provided between the vehicle frame and the carrier plate, and the height adjustment structure facilitates the passage of height restriction facilities by adjusting the height of the transport vehicle chassis.

[0008] The limiting plate is symmetrically provided with reinforcing limiting components on both the left and right ends, and the reinforcing limiting components improve the stability of the pressure steel pipe body when the chassis height is adjusted.

[0009] Furthermore, the height adjustment structure includes an adjustment frame disposed between the vehicle frame and the carrier plate. The adjustment frame is configured as an "X" shaped structure. The top and bottom ends of the adjustment frame are hinged with sliders. The upper and lower sliders are respectively slidably connected to the slide grooves symmetrically opened at the top of the vehicle frame and the bottom of the carrier plate.

[0010] Furthermore, an electric push rod is installed in the slide groove, and the end of the electric push rod is fixedly connected to the side of the slider. The adjusting frame forms an opening and closing rotation structure through the electric push rod and the slider.

[0011] Furthermore, sleeves are symmetrically installed on the front and rear sides of the bottom of the carrier plate, and a piston plate is slidably connected to the bottom of the sleeve. The bottom of the piston plate is fixedly connected to the top of the frame, and oil is provided inside the sleeve.

[0012] Furthermore, the reinforcing limiting component includes a sliding plate fixed to the bottom of the contact plate, the sliding plate being slidably connected in a sliding cavity, the sliding cavity being symmetrically opened on the front and rear sides of the top of the limiting plate, and the sliding cavity being connected to the inside of the sleeve through a first connecting pipe.

[0013] Furthermore, the contact plate is configured as a hollow rectangular structure, the contact plate abuts against the outer side of the pressure steel pipe body, and the contact plate is located between adjacent reinforcing ribs.

[0014] Furthermore, the left and right sides of the contact plate are sealed and slidably connected with reinforcing plates, the inner middle part of the contact plate is connected to the inside of the sleeve through the second connecting pipe, and the outer end of the reinforcing plate is pressed and abutted against the reinforcing rib.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This pressure steel pipe transport vehicle, which can reduce chassis height, can pass through bridges, culverts and other weight and height restriction facilities during transportation by lowering the chassis height. At the same time, while adjusting the height, it strengthens the limiting and fixing of the steel pipes, improving the stability of the steel pipes during transportation.

[0017] 1. Furthermore, when adjusting the chassis height, the electric push rod is activated, which pushes the front and rear sliders to move synchronously in the slide groove. After the sliders slide, the opening and closing angle of the adjustment frame changes. After the angle of the adjustment frame changes, the height of the carrier plate is adjusted, thereby reducing the overall height of the pressure steel pipe body, making it easier to pass through some height-restricted facilities.

[0018] 2. Furthermore, when the height of the carrier plate is adjusted, the piston plate will slide synchronously inside the sleeve, thereby squeezing out the oil inside the sleeve. The oil inside the sleeve is then output through the first connecting pipe and the second connecting pipe respectively.

[0019] 3. Furthermore, the oil in the first connecting pipe is also injected into the sliding cavity. After the oil is injected into the sliding cavity, it will push the slide plate to move outward. After the slide plate moves, it will drive the contact plate to move synchronously. The contact plate will then come into closer contact with the outside of the pressure steel pipe body, thereby applying a clamping force from the front and rear sides.

[0020] 4. Furthermore, the second connecting pipe injects oil into the inner middle of the contact plate, thereby causing the reinforcing plate to slide out from both sides of the contact plate. After the reinforcing plate slides out, it presses against the outer reinforcing rib of the pressure steel pipe body, thereby providing a left and right side contact limiting force, which further improves the stability of the pressure steel pipe body during transportation.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: Please refer to Figure 1 - Figure 6 The present invention provides the following technical solution: a pressure steel pipe transport vehicle that can reduce chassis height, including a frame 1, the frame 1 being used for later connection with a truck, wheels 2 being equally spaced on the front and rear sides of the frame 1, a carrier plate 3 being provided on the top of the frame 1, a limiting plate 8 being symmetrically provided on the top of the carrier plate 3, a pressure steel pipe body 17 being mounted on the limiting plate 8, reinforcing ribs 18 being equally spaced on the outer side of the pressure steel pipe body 17, a height adjustment structure being provided between the frame 1 and the carrier plate 3, and the height adjustment structure facilitating passage of height restriction facilities by adjusting the chassis height of the transport vehicle, and reinforcing limiting components being symmetrically provided on the left and right ends of the limiting plate 8, and the reinforcing limiting components improving the stability of the pressure steel pipe body 17 when the chassis height is adjusted;

[0030] In use, the pressure steel pipe body 17 is placed on the limiting plate 8 on the carrier plate 3. The limiting plate 8 is located in the gap between the adjacent reinforcing ribs 18. During transportation, the right end of the frame 1 is connected to the truck for towing. When encountering height restriction facilities during transportation, the height adjustment structure between the frame 1 and the carrier plate 3 is adjusted to lower the height of the transport vehicle chassis, thereby facilitating passage. At the same time as the height is adjusted, the reinforcing limiting component will strengthen the limiting and fixing of the pressure steel pipe body 17 to prevent the pressure steel pipe body 17 from moving during transportation.

[0031] Please refer to Figure 1 - Figure 3 As shown, the height adjustment structure includes an adjustment frame 4 disposed between the frame 1 and the carrier plate 3. The adjustment frame 4 is configured as an "X" shaped structure. The top and bottom ends of the adjustment frame 4 are hinged with sliders 5. The upper and lower sliders 5 are respectively slidably connected to the top of the frame 1 and the bottom of the carrier plate 3 in symmetrically opened grooves 6. An electric push rod 7 is installed in the groove 6. The end of the electric push rod 7 is fixedly connected to the side of the slider 5. The adjustment frame 4 forms an opening and closing rotation structure through the electric push rod 7 and the slider 5.

[0032] When the chassis height needs to be adjusted during use, the electric push rod 7 is activated. The electric push rod 7 will push the sliders 5 on the front and rear sides to move synchronously in the slide groove 6. After the sliders 5 slide, the opening and closing angle of the adjustment frame 4 will change. After the angle of the adjustment frame 4 changes, the height of the carrier plate 3 will be adjusted, thereby reducing the overall height of the pressure steel pipe body 17, making it easier to pass through some height-limiting facilities.

[0033] Example 2:

[0034] Based on Embodiment 1, a sleeve 10 and a piston plate 11 are also disclosed. Please refer to [reference needed]. Figure 4 - Figure 5 As shown, its specific structure is as follows: Sleeves 10 are symmetrically installed on the front and rear sides of the bottom of the carrier plate 3. Piston plate 11 is slidably connected to the bottom of sleeve 10. The bottom of piston plate 11 is fixedly connected to the top of frame 1. Oil is provided inside sleeve 10.

[0035] During use, when the height of the carrier plate 3 is adjusted, the piston plate 11 will slide synchronously inside the sleeve 10, thereby squeezing out the oil inside the sleeve 10.

[0036] Example 3:

[0037] Based on Embodiment 2, a reinforcing plate 16 is also disclosed; please refer to [reference needed]. Figure 4 - Figure 6 As shown, its specific structure is as follows: The reinforcing limiting component includes a sliding plate 14 fixed to the bottom of the contact plate 9. The sliding plate 14 is slidably connected to the sliding cavity 13. The sliding cavity 13 is symmetrically opened on the front and rear sides of the top of the limiting plate 8. The sliding cavity 13 is connected to the inside of the sleeve 10 through the first connecting pipe 12. The contact plate 9 is set as a hollow rectangular structure. The contact plate 9 abuts against the outside of the pressure steel pipe body 17, and the contact plate 9 is located between adjacent reinforcing ribs 18. The left and right sides of the contact plate 9 are slidably connected to reinforcing plates 16. The middle part of the inner side of the contact plate 9 is connected to the inside of the sleeve 10 through the second connecting pipe 15. The outer end of the reinforcing plate 16 is pressed against the reinforcing rib 18.

[0038] During use, the oil inside the sleeve 10 is output through the first connecting pipe 12 and the second connecting pipe 15 respectively. The oil in the first connecting pipe 12 is also injected into the sliding cavity 13. After the oil is injected into the sliding cavity 13, it will push the slide plate 14 to move outward. After the slide plate 14 moves, it will drive the abutment plate 9 to move synchronously. The abutment plate 9 will then come into closer contact with the outside of the pressure steel pipe body 17, thereby applying a clamping force on the front and rear sides and improving the stability during transportation. At the same time, the second connecting pipe 15 injects oil into the inner middle of the abutment plate 9, thereby causing the reinforcing plate 16 to slide out from both sides of the abutment plate 9. After the reinforcing plate 16 slides out, it presses against the reinforcing rib 18 on the outside of the pressure steel pipe body 17, thereby providing a left and right side abutment limiting force, and further improving the stability of the pressure steel pipe body 17 during transportation.
