Description

Technical Field

[0001] This utility model relates to the field of construction engineering equipment technology, specifically a new type of secondary concrete placing machine. Background Technology

[0002] Concrete is a commonly used building material in the construction industry. A concrete placing boom is the final piece of equipment for pumping concrete, its function being to transport pumped concrete through pipelines to the location where the component to be poured will be. Because the placing boom delivers concrete via pump, there will be some swaying during the placement process. To stabilize the placing boom frame, existing secondary concrete placing booms typically add counterweights. However, the presence of this load increases the difficulty of moving the placing boom, especially on uneven or uphill terrain, when the placing boom needs to be moved to a different location. Furthermore, the concrete delivery pipes are installed through the placing boom frame, generally using a mechanical rigid connection, requiring multiple connection points. This cumbersome connection method and complex disassembly process make maintenance and replacement inconvenient.

[0003] This utility model proposes a novel secondary concrete placing machine to solve the above-mentioned technical problems. Utility Model Content

[0021] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0022] Specific implementation case 1:

[0023] A novel secondary concrete placing boom includes: a frame body 1, a feeding pipe 3, a bend 4, and a vibration buffer assembly 5. The upper end of the feeding pipe 4 is provided with a connector, and the lower end is connected to the bend 4. The feeding pipe 3 is installed in the internal space of the frame body 1. The vibration buffer assembly 5 is installed on the other two sides of the frame body 1. The vibration buffer assembly 5 is used to prevent the boom from tipping over due to excessive vibration during operation.

[0024] The vibration damping assembly 5 includes a connecting plate 51, a support plate 52, a damping spring 53, and a damping rod 54. The connecting plate 51 is fixed to the middle frame of the side plate of the frame body 1. One or more support plates 52 are arranged in the height direction of the connecting plate 51. The damping rod 54 is located in the mounting hole of the support plate 52. The length segments of the damping rod 54 adjacent to two support plates 52 are fitted with retaining rings. The damping rod 54 is fitted with the damping spring 53. The upper and lower ends of the damping spring 53 abut against the retaining rings and the support plate 52, respectively. The damping spring 53 is always in a compressed state.

[0025] The buffer rod 54 in the vibration buffer assembly 5 can be connected to the counterweight in the field or inserted into the ground. Part of the vibration energy generated during the laying process of the concrete placing machine is transmitted to the counterweight or the ground through the vibration buffer assembly 5, thereby reducing the amplitude of the concrete placing machine itself and improving the laying stability of the concrete placing machine.

[0026] Specific Implementation Case 2:

[0027] A novel secondary concrete placing boom includes: a frame body 1, a feeding pipe 3, and a bend 4. The upper end of the feeding pipe 4 is provided with a connector, and the lower end is connected to the bend 4. The feeding pipe 3 is installed in the internal space of the frame body 1. The feeding pipe 3 is fixed to the frame body 1 by a push-up clamping ring assembly 6. The push-up clamping ring assembly 6 includes a fixed clamping ring 61, a movable clamping ring 62, a push-up screw 63, a return spring 64, and a hollow rectangular plate 65. The hollow rectangular plate 65 is fixedly connected to the frame body 1. The push-up screw 63 passes through a threaded hole on the surface of the hollow rectangular plate 65 and its end abuts against the rear plate surface of the movable clamping ring 62. The rear plate surface of the movable clamping ring 62 is connected to the hollow rectangular plate 65 by a connecting rod. The return spring 64 is provided between the rear end of the connecting rod and the front plate surface of the hollow rectangular plate 65.

[0028] Rotating the push screw 63 via the external handle causes the movable clamp ring 62 to move toward the fixed clamp ring 61, squeezing and fixing the feeding pipe 3 located within the fixed clamp ring 61 and the movable clamp ring 62. After rotating the push screw 63 in the opposite direction, the movable clamp ring 62 moves toward the side away from the fixed clamp ring 61 under the restoring force of the return spring 64. This operation has a high safety factor and a small working space. The return spring 64 can also absorb some vibration energy.

[0029] Specific Implementation Case 3:

[0030] A novel secondary concrete placing boom includes: a frame body 1, a lifting support 2, a feeding pipe 3, a bend 4, and a vibration buffer assembly 5. The upper end of the feeding pipe 4 is equipped with a connector, and the lower end is connected to the bend 4. The feeding pipe 3 is installed inside the frame body 1. The lifting support 2 is installed on both sides of the frame body 1, and the vibration buffer assembly 5 is installed on the other two sides of the frame body 1. The vibration buffer assembly 5 prevents the boom from tipping over due to excessive vibration during operation. The specific structure of the vibration buffer assembly 5 is the same as in specific implementation example 1.

[0031] Optionally, a mobile trolley 7 is also included. The mobile trolley 7 is used to move the secondary fabric placing machine. The mobile trolley 7 includes a trolley body 71 and a mobile auxiliary support 72. The mobile auxiliary support 72 includes a first rotating rod 721, a U-shaped second rotating rod 722, a U-shaped third rotating rod 723, a connecting rod 724, and a rear baffle plate 725. One end of the first rotating rod 721 is rotatably connected to the handle of the trolley body 71, and the other end of the first rotating rod 721 is rotatably connected to the second rotating rod 722. The U-shaped second rotating rod 722 and the third rotating rod 723 are rotatably connected to the front and rear ends of the support base plate of the trolley body 71, respectively. The second rotating rod 722 and the third rotating rod 723 are rotatably connected to both ends of the connecting rod 724, respectively. The third rotating rod 723 is fixed with multiple rear baffle plates 725.

[0032] By rotating the handle of the trolley body 71, the second rotating rod 722 and the third rotating rod 723 are rotated, and the rear baffle plate 725 supports the rear of the fabric placing machine from the rear to prevent it from tipping over during the transfer process.

[0033] Optionally, the mobile trolley 7 has a buffer rod clearance groove 711 machined on the plate surface of the trolley body 71, and a rolling bearing is sleeved on the lower end of the buffer rod 54. The buffer rod 54 can slide smoothly along the buffer rod clearance groove 711 through the action of the rolling bearing. In addition, the buffer rod 54 can avoid positional displacement during the transfer process through the limiting effect of the buffer rod clearance groove 711.

[0034] Optionally, the lifting support 2 is a hand-cranked jack structure, and the lifting support 2 is detachably installed from the frame body 1. The hand-cranked jack structure allows the frame body 1 to be raised to the height of the transfer trolley, facilitating changes in usage location.
