DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] In order to solve the problem in the prior art that the flexible delivery pipe is easily restricted by the position and angle of the pump truck output pipe, forcing the pump truck to frequently adjust its position and angle, resulting in low construction efficiency, the following technical solution is provided. Please refer to Figure 1-5 ;

[0025] An auxiliary conveying device for pouring concrete on a pump truck comprises a pump truck output pipe 1 and a flexible conveying pipe 2. The port of the pump truck output pipe 1 is connected to the flexible conveying pipe 2 through an auxiliary adjusting member. The auxiliary adjusting member comprises a double-headed universal tube 3 and a spherical joint 4. Two spherical joints 4 are provided and are respectively located at the two ends of the double-headed universal tube 3. The two ends of the double-headed universal tube 3 are connected with a spherical tube 31. The spherical tube 31 is located in the spherical joint 4. The double-headed universal tube 3 can form a certain rotation angle with the spherical joint 4 through the spherical tube 31. One of the spherical joints 4 is connected to the pump truck output pipe 1 through a first flange 11, and the other spherical joint 4 is connected to the flexible conveying pipe 2 through a second flange 21.

[0026] The spherical joint 4 includes a first hemispherical part 41 and a second hemispherical part 42. The outer edges of the contact surfaces of the first hemispherical part 41 and the second hemispherical part 42 are respectively provided with a third flange 43. The first hemispherical part 41 and the second hemispherical part 42 are spliced ​​by the third flange 43. The first hemispherical part 41 and the second hemispherical part 42 form a cavity for the spherical tube 31 to slide inside. The spherical tube 31 and the cavity are both standard spheres. Therefore, the spherical tube 31 can rotate freely in the cavity within a certain range, so that the two sides of the double-headed universal tube 3 form a certain rotation angle with the pump truck output pipe 1 and the flexible conveying pipe 2 respectively, thereby assisting the flexible conveying pipe 2 to flexibly adjust the conveying direction and no longer be limited by the position and angle of the pump truck output pipe 1. The outer wall of the spherical tube 31 is closely fitted with the first hemispherical part 41 and the second hemispherical part 42 to prevent concrete from entering the gap between the spherical tube 31 and the first hemispherical part 41 and the second hemispherical part 42.

[0027] A first opening 411 is provided in the axial direction of the first hemispherical member 41, and a second opening 421 is provided in the axial direction of the second hemispherical member 42. The diameter of the second opening 421 is larger than that of the first opening 411. The spherical tube 31 runs through the second opening 421. The diameter of the second opening 421 and the diameter of the double-headed universal tube 3 determine the rotation amplitude of the spherical tube 31 in the cavity. A third opening 311 is provided at one end of the spherical tube 31 facing the pump truck output pipe 1 / flexible delivery pipe 2. The diameter of the third opening 311 is not smaller than that of the second opening 421. The first opening 411 is always kept within the rotation coverage range of the third opening 311, so that concrete can smoothly enter the third opening 311 from the first opening 411. The spherical tube 31, the first hemispherical member 41 and the second hemispherical member 42 on both sides of the double-headed universal tube 3 are symmetrically distributed.

[0028] Concrete is output from the pump truck output pipe 1, enters the first spherical joint 4 through the first opening 411, enters the first spherical tube 31 through the third opening 311 in the spherical joint 4, then flows into the double-headed universal tube 3, and then enters the second spherical joint 4 through the next spherical tube 31, and finally enters the flexible conveying pipe 2.

[0029] The first flange 11, the second flange 21 and the third flange 43 are provided with a quick locking ring 5 on the outside. The quick locking ring 5 is composed of two semi-circular parts, one corresponding end of which is pivotally connected, and the other end of the semi-circular parts is provided with an internal thread block 51, and locking bolts 52 penetrate the two internal thread blocks 51. The quick locking ring 5 is provided with an annular groove 53 inside, and the two opposite side walls of the annular groove 53 gradually narrow from the center to the periphery, and a sealing rubber ring 54 is provided on the bottom surface of the annular groove 53. The sizes of the first flange 11, the second flange 21 and the two third flanges 43 may be different in actual situations, so the size of the quick locking ring 5 is adjusted according to actual situations, but the connection method is the same. Here, the third flange 43 is taken as an example. When connecting, the quick locking ring 5 is opened and the annular groove 53 is aligned with the two spliced ​​third flanges 43, then the semi-circular parts are merged, the locking bolts 52 are inserted into the two internal thread blocks 51 and tightened with nuts, and the third flange 43 gradually penetrates into the annular groove 53 and keeps moving closer in the gradually narrowing side wall of the annular groove 53 until it fits tightly, so that the first hemispherical parts 41 and the second hemispherical parts 42 on both sides of the third flange 43 are firmly connected, and the sealing rubber ring 54 further seals the gap between the third flange 43 to prevent moisture in the concrete from seeping out.

[0030] Working principle: The spherical tube 31 can rotate freely to a certain extent in the circular cavity formed by the first hemispherical part 41 and the second hemispherical part 42. Therefore, the double-headed universal tube 3 can form a flexible rotation angle with the pump truck output pipe 1 and the flexible delivery pipe 2 connected to the first hemispherical parts 41 on both sides thereof, thereby assisting the flexible delivery pipe 2 to flexibly adjust the delivery direction.
