Anti-explosion double-power telescopic arm type diesel engine concrete pump car

Abstract

The invention discloses an anti-explosion double-power telescopic arm type diesel engine concrete pump car. The anti-explosion double-power telescopic arm type diesel engine concrete pump car comprises a car head, wheels, a concrete roller, a car body frame and an unfolding arm frame; the car head is mounted and connected with the car body frame; the wheels are mounted on the car head and the carbody frame; the concrete roller is mounted on the car body frame; the unfolding arm frame is embedded in the car head and the car body frame; the unfolding arm frame consists of double extension arms,a middle frame, an outer frame and a clamping structure; when single arms extend, the double extension arms are of double arm structures; the middle frame achieves a fixation reinforcing effect; theclamping structure realizes auxiliary improvement of the transmission stability of the double extension arms; extension joints and plate embedding structures realize stable extension of the single arms, so that the stability and the safety of the whole equipment are effectively guaranteed during operation in weathers with higher wind power; transmission shaft rods are used for quickly unbuckling or locking the extension joints at abnormal times to further improve the safety; and the clamping structure realizes auxiliary improvement of the transmission stability of the double extension arms, and accelerates the extension moving speed of the double extension arms to achieve high operation efficiency.

Description

technical field [0001] The invention relates to the field of concrete, in particular to an explosion-proof dual-power telescopic arm diesel engine concrete pump truck. Background technique [0002] Grouting and silt are sent into the concrete pump truck, and the mud is formed after mixing, and then transported to the designated project site for pile filling. When pouring mud, you can choose to dump it with a roller or with a long arm according to the terrain and distance. The roller is used for The ground is dumped at close range, and the long arm is used for long-distance dumping at high places, which is convenient and flexible to use. [0003] In the prior art, the rack arm is generally installed on the outside of the vehicle body adjacent to the roller. When the roller or the long arm is used alone, it will be inconvenient to rotate or stretch because they are relatively close to each other. The smoothness of the roller rotation needs to be improved. The long arm The sta...

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the deficiencies of the prior art and provide an explosion-proof dual-power telescopic arm type diesel engine concrete pump truck to solve the problem that the frame arm is generally installed outside the body and adjacent to the roller, and the roller or long arm is used alone Sometimes it will be inconvenient to rotate or stretch because they are relatively close to each other. The smoothness of the rotation of the drum needs to be improved, and the stability of the long arm when stretched is poor, especially when operating in windy weather. The overall stability and safety of the equipment cannot be effectively guaranteed, and the operating efficiency cannot be effectively improved
