Description

Technical Field

[0001] The utility model relates to the field of precast pipe pile transportation, in particular to a transportation trolley for producing precast pipe piles. Background Art

[0002] Pipe piles are divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles, prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-wall pipe piles (PTC pipe piles), and high-strength prestressed concrete pipe piles (PHC pipe piles). The pre-tensioned prestressed pipe pile is a kind of hollow cylindrical slender concrete precast component made by the pre-tensioned prestressed process and the centrifugal forming method, mainly composed of a cylindrical pile body, an end plate, a steel sleeve hoop, etc.

[0003] The pipe pile sizes required in different sites are different. Some pipe piles with smaller sizes will be transported by a trolley. However, in the prior art, most of the transportation trolleys have a single structure and can only simply fix the pipe pile and transport it to the installation site. When the pipe pile is transported to the installation site, the pipe pile needs to be unloaded. Since the weight of the concrete pipe pile is relatively large, if the transportation trolley cannot assist in the unloading work, a large amount of labor and external equipment are required to unload the pipe pile, resulting in a time-consuming and laborious process, affecting the handling efficiency of the filling, and at the same time posing a safety hazard to the on-site operators. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the prior art, if the transportation trolley cannot assist in the unloading work, a large amount of labor and external equipment are required to unload the pipe pile, resulting in a time-consuming and laborious process, affecting the handling efficiency of the filling, and at the same time posing a safety hazard to the on-site operators and other problems, the utility model provides a transportation trolley for producing precast pipe piles.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a transportation trolley for producing precast pipe piles, including a vehicle frame, walking wheels are arranged on both sides of the vehicle frame, a push rod is fixedly connected to one side of the vehicle frame, a third connection seat is fixedly connected to the top of the vehicle frame, a first connection seat is fixedly connected to the top of the vehicle frame, the number of the first connection seats is two, a turning plate is rotatably connected to the opposite sides of the two first connection seats, and a transmission mechanism is arranged between the turning plate and the vehicle frame;

[0006] The transmission mechanism includes a hydraulic cylinder, the hydraulic cylinder is fixedly communicated with a hydraulic rod, one end of the hydraulic rod is rotatably connected to a second connection seat, a slide rail is fixedly connected to the bottom of the turning plate, the slide rail is slidably connected with the second connection seat, and a support mechanism is arranged between both sides of the turning plate and the vehicle frame.

[0007] Preferably, the support mechanism includes a connecting rod rotatably connected to the flap. One end of the connecting rod is rotatably connected to a fourth connecting seat. The bottom of the fourth connecting seat is fixedly connected to a slider, and a first fixing hole is formed through one side of the slider.

[0008] Preferably, a chute is formed at the top of the vehicle frame. The sliders are respectively slidably connected to the corresponding chutes. A second fixing hole is formed at one side of the vehicle frame, and the second fixing hole communicates with the chute. A fixing bolt is inserted between the second fixing hole and the first fixing hole.

[0009] Preferably, a counterweight box is fixedly connected to the bottom of the vehicle frame, and a plurality of counterweight blocks are arranged in the inner cavity of the counterweight box.

[0010] Preferably, a support seat is fixedly connected to the top of the vehicle frame, and a plurality of anti-slip strips are fixedly connected to the top of the support seat.

[0011] Preferably, a bracket is fixedly connected to the top of the vehicle frame. An adjusting rod is threadedly connected to the inner cavity of the bracket. One end of the adjusting rod is rotatably connected to a clamping plate, and an adjusting handle is fixedly connected to one end of each adjusting rod.

[0012] Preferably, a limiting rod is fixedly connected to the surface of the clamping plate. The limiting rod is slidably connected to the bracket, and a limiting plate is fixedly connected to one end of the limiting rod.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The flap is integrally connected to the vehicle frame through the first connecting seat. Special-sized pipe piles can be transported to the top of the flap by a crane. The pipe piles can be transported through the cooperation of the push-pull rod and the walking wheels. When the pipe piles are transported to the installation site, the hydraulic cylinder can be activated through the control panel. The hydraulic cylinder drives the hydraulic rod to push the bottom of the flap, and the flap rotates around the first connecting seat as the center, so that a certain angle is formed between the flap and the vehicle frame. When the angle of the flap continues to increase, the hydraulic rod will slide along one end of the slide rail to one end through the second connecting seat, so that the hydraulic rod has a longer extension space. When the flap is flipped to the maximum angle, the support mechanism stands at the angle between the flap and the vehicle frame to support the flap, ensuring the support strength of the flap. Therefore, the device has a compact structure, and the pipe piles can be unloaded from the transport cart by means of the flip-up flap, saving labor consumption and improving the transport efficiency of the pipe piles.

[0015] 2. While the flap rotates, one end of the connecting rod rotates around the side wall of the flap as the center, and one end of the connecting rod rotates along the fourth connecting seat and drives the slider to slide along the chute. When the flap is flipped to the maximum angle, the first fixing hole corresponds to the second fixing hole at the edge. The slider and the vehicle frame can be fixed into one body through the fixing bolt, and the connecting rod supports the flap, improving the support strength of the flap.

[0016] 3. The counterweight can be made of materials such as concrete. After the counterweight is placed in the counterweight box, it increases the weight on the side of the frame away from the axis of the tipping plate, and tries to avoid the frame from tipping over due to a large tipping plate angle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] The following further elaborates on this application Figures 1-4 and makes a more detailed description of it.

[0025] An embodiment of the present application discloses a transport trolley for producing precast pipe piles. Refer to Figure 1 and Figure 2 , a transport trolley for producing precast pipe piles, including a vehicle frame 1, walking wheels 2 are arranged on both sides of the vehicle frame 1, a push rod 3 is fixedly connected to one side of the vehicle frame 1, a third connecting seat 7 is fixedly connected to the top of the vehicle frame 1, a first connecting seat 4 is fixedly connected to the top of the vehicle frame 1, the number of the first connecting seats 4 is two, a turning plate 5 is rotatably connected to the opposite sides of the two first connecting seats 4, and a transmission mechanism 6 is arranged between the turning plate 5 and the vehicle frame 1;

[0026] The transmission mechanism 6 includes a hydraulic cylinder 601, the hydraulic cylinder 601 is fixedly communicated with a hydraulic rod 602, one end of the hydraulic rod 602 is rotatably connected to a second connecting seat 603, a slide rail 8 is fixedly connected to the bottom of the turning plate 5, and the slide rail 8 is slidably connected with the second connecting seat 603. A support mechanism 9 is arranged between both sides of the turning plate 5 and the vehicle frame 1. The turning plate 5 is integrally connected to the vehicle frame 1 through the first connecting seat 4. Pipe piles of special sizes can be transported to the top of the turning plate 5 by a crane. The pipe piles can be transported through the cooperation of the push rod 3 and the walking wheels 2. When the pipe piles are transported to the installation site, the hydraulic cylinder 601 can be activated through a control panel (not shown in the figure). The hydraulic cylinder 601 drives the hydraulic rod 602 to push the bottom of the turning plate 5, and the turning plate 5 rotates around the first connecting seat 4, so that a certain angle is formed between the turning plate 5 and the vehicle frame 1. When the angle of the turning plate 5 continues to increase, the hydraulic rod 602 will slide along one end of the slide rail 8 to one end through the second connecting seat 603, so that the hydraulic rod 602 has a longer extension space. When the turning plate 5 is turned to the maximum angle, the support mechanism 9 stands at the included angle between the turning plate 5 and the vehicle frame 1 to support the turning plate 5 and ensure the support strength of the turning plate 5. Therefore, the device has a compact structure, and the pipe piles can be unloaded from the transport trolley with the assistance of the turnable turning plate 5, saving labor consumption and improving the transport efficiency of the pipe piles.

[0027] Refer to Figure 2 and Figure 3, the support mechanism 9 includes a connecting rod 901 rotatably connected to the flap 5. One end of the connecting rod 901 is rotatably connected to a fourth connecting seat 902. The bottom of the fourth connecting seat 902 is fixedly connected to a slider 903. A first fixing hole 904 is formed through one side of the slider 903. A chute 10 is formed at the top of the vehicle frame 1. The sliders 903 are respectively slidably connected to the corresponding chutes 10. A second fixing hole 11 is formed on one side of the vehicle frame 1. The second fixing hole 11 communicates with the chute 10. A fixing bolt 12 is inserted between the second fixing hole 11 and the first fixing hole 904. While the flap 5 rotates, one end of the connecting rod 901 rotates around the side wall of the flap 5 as the center. One end of the connecting rod 901 rotates along the fourth connecting seat 902 and drives the slider 903 to slide along the chute 10. When the flap 5 is flipped to the maximum angle, the first fixing hole 904 corresponds to the second fixing hole 11 at the edge. The slider 903 and the vehicle frame 1 can be fixed into one body through the fixing bolt 12, and the connecting rod 901 supports the flap 5 to improve the support strength of the flap 5;

[0028] In addition, the flap 5 needs to be flipped by different angles for different sizes of pipe piles. The flap 5 at different angles can be supported through multiple second fixing holes 11.

[0029] Refer to Figure 2 , a counterweight box 13 is fixedly connected to the bottom of the vehicle frame 1. A plurality of counterweight blocks 22 are arranged in the inner cavity of the counterweight box 13. The counterweight blocks 22 can be made of materials such as concrete. After the counterweight blocks 22 are placed in the counterweight box 13, the weight on the side of the vehicle frame 1 away from the axis of the flap 5 is increased, and the vehicle frame 1 is prevented from tipping over due to the large angle of the flap 5 as much as possible.

[0030] Refer to Figure 4 , a support seat 14 is fixedly connected to the top of the vehicle frame 1. A plurality of anti-slip strips 15 are fixedly connected to the top of the support seat 14. The surface of the support seat 14 is arc-shaped so that the cylindrical pipe pile can be placed between the support seats 14. The anti-slip strips 15 can be made of rubber material to increase the friction between the pipe pile and the support seat 14.

[0031] Refer to Figure 4 , a bracket 16 is fixedly connected to the top of the vehicle frame 1. An adjusting rod 17 is threadedly connected to the inner cavity of the bracket 16. One end of the adjusting rod 17 is rotatably connected to a clamping plate 18. An adjusting handle 19 is fixedly connected to one end of the adjusting rod 17. The adjusting rod 17 can be driven to rotate through the adjusting handle 19. Since the adjusting rod 17 is threadedly connected to the bracket 16, when the adjusting rod 17 rotates to one side, the clamping plate 18 is pushed closer to the pipe pile, so that the clamping plate 18 fits the surface of the pipe pile. After both clamping plates 18 fit, the stability of the pipe pile placement is improved.

[0032] Refer to Figure 4, a limiting rod 20 is fixedly connected to the surface of the clamping plate 18. The limiting rod 20 is slidably connected to the bracket 16. One end of the limiting rod 20 is fixedly connected to a limiting plate 21. While the clamping plate 18 is pushed by the adjusting rod 17, the limiting rod 20 is driven to slide along the bracket 16 to limit the clamping plate 18, ensuring the lateral movement of the clamping plate 18, and the limiting plate 21 can limit the distance of the limiting rod 20.

[0033] Working principle: The pipe piles with special sizes are placed between the supporting seats 14. The adjusting rod 17 can be driven to rotate by the adjusting handle 19. When the adjusting rod 17 rotates to one side, it pushes the clamping plate 18 towards the pipe pile, making the clamping plate 18 fit the surface of the pipe pile. After both clamping plates 18 are fitted, the stability of the pipe pile placement is improved. The pipe pile can be transported through the cooperation of the push-pull rod 3 and the walking wheels 2. When the pipe pile is transported to the installation site, the hydraulic cylinder 601 can be activated through the control panel. The hydraulic cylinder 601 drives the hydraulic rod 602 to push the bottom of the flap 5. The flap 5 rotates around the first connecting seat 4, so that an angle is formed between the flap 5 and the vehicle frame 1. When the angle of the flap 5 continues to increase, the hydraulic rod 602 will slide along one end of the slide rail 8 to one end through the second connecting seat 603, enabling the hydraulic rod 602 to have a longer extension space. When the flap 5 is flipped to the maximum angle, the support mechanism 9 stands at the angle between the flap 5 and the vehicle frame 1 to support the flap 5 and ensure the support strength of the flap 5. Thus, the device has a compact structure. The pipe pile can be unloaded from the transport cart with the assistance of the flip-up flap 5, saving labor consumption and improving the transport efficiency of the pipe pile.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
