Technical Field

[0001] The utility model relates to the technical field of double-arm material placing machines, in particular to a double-arm material placing machine. Background Art

[0002] A concrete double-arm placing boom is a device used in a concrete mixing plant or a concrete mixer truck. It is usually used to produce large quantities of concrete, such as at a construction site or a concrete prefabrication plant. The device usually consists of two rotating arms, each of which is equipped with an agitator. During the mixing process, the two arms can rotate and move simultaneously or alternately to ensure that the concrete is evenly mixed.

[0003] At present, when the existing double-arm concrete placing boom is in use, when concrete enters the pipeline, the weight of the end of the machine body away from the counterweight assembly increases, which may affect the stability of the equipment during use. Therefore, it is necessary to design a double-arm placing boom. Utility Model Content

[0025] In this embodiment, the device is provided with inclination sensors 15 at the bottom ends of both sides of the beam frame 1. When the inclination sensor 15 detects that there is a certain angle change in the beam frame 1, the motor 9 is controlled to start. After the motor 9 is started, the screw rod 8 is controlled to rotate, and the screw rod 8 drives the counterweight seat 5 to move laterally. When the counterweight seat 5 moves laterally at the end of the beam frame 1 away from the tubular fixed arm 2, the center of gravity of the beam frame 1 can be adjusted in real time, thereby improving the balance of the equipment during use.

[0026] like Figure 1 and Figure 3 As shown, a hanging head 11 is provided at the top of the tubular movable arm 3 on the side close to the rotary joint 1 4, a hanging head 2 12 is provided at the top of the tubular movable arm 3 on the side away from the rotary joint 1 4, a bracket 13 is provided at the top of the beam frame 1 on the side away from the counterweight seat 5, and a guide sleeve 14 is integrally formed at the top of the bracket 13;

[0027] In this embodiment, the lifting head 11 and the lifting head 2 12 in the device are respectively connected to a steel cable, and the two steel cables are connected to two externally configured winches after passing through the guide sleeve 14. When it is necessary to control the tubular movable arm 3 to swing from the middle of the beam frame 1 to the outside, one of the winches is used to control the steel cable to be reeled in, and the steel cable pulls the lifting head 2 12, so that the end of the tubular movable arm 3 swings to one side.

In this way, after the tubular movable arm 3 is reset, it will not swing left and right with the wind, thereby improving the structural stability of the equipment.

[0030] Working principle: The device is provided with inclination sensors 15 at the bottom ends of both sides of the beam frame 1.

After the motor 9 is started, the screw rod 8 is controlled to rotate, and the screw rod 8 drives the counterweight seat 5 to move laterally. When the counterweight seat 5 moves laterally at the end of the beam frame 1 away from the tubular fixed arm 2, the center of gravity of the beam frame 1 can be adjusted in real time, thereby improving the balance of the equipment when in use; when the tubular movable arm 3 is reset to the bottom of the beam frame 1, the positioning sensor 18 will detect the positioning piece 19, and then control the electric push rod 16 to start. After the electric push rod 16 is started, it drives the clamping head 17 at the output shaft end to press down and clamp from the upper end of the tubular movable arm 3. In this way, after the tubular movable arm 3 is reset, it will not swing left and right with the blowing of the wind, thereby improving the structural stability of the equipment.
