[0039] See also Figure 1 , Figure 2 The bracket 12 is used to be arranged on the right side of the hydraulic trestle 10, and is fixedly connected to the main beam of the hydraulic trestle 10 by bolts and other fasteners. The first track 13 is parallel to the second track 14, both of which extend along the direction of the hydraulic trestle 10, and the first track 13 and the second track 14 are arranged on the bracket 12 at intervals from left to right. The installation height of the first track 13 is higher than the installation height of the second track 14, so that there is a height difference between the first track 13 and the second track 14, and the height difference between the two is adjustable. The chute 11 is a long strip trough structure surrounded by a bottom plate and two side plates, and is used to transport concrete; the chute 11 is arranged across the first track 13 and the second track 14, and not only the chute 11 is supported by the first track 13 and the second track 14, so that the chute 11 is arranged obliquely downward from left to right, but also the movement of the chute 11 is guided, so that the chute 11 moves back and forth on the first track 13 and the second track 14 along the direction of the hydraulic trestle 10, and the inclination angle of the chute 11 can be adjusted by adjusting the height difference between the first track 13 and the second track 14.

[0040] The hydraulic trestle mobile concrete unloading device provided in the embodiment of the present application is used to transport the concrete in the concrete tank truck on the hydraulic trestle 10 to the construction position on one side of the hydraulic trestle 10 through the chute 11. In the process of transporting concrete, the position of the chute 11 can be adjusted by only pushing the chute 11 to move on the first track 13 and the second track 14, without the need to manually move the chute 11 back and forth, thereby reducing the labor intensity of workers and improving construction efficiency; by adjusting the height difference between the first track 13 and the second track 14, the inclination angle of the chute 11 can also be adjusted, thereby adjusting the conveying speed of the concrete in the chute 11, so as to achieve the purpose of fast and uniform concrete unloading.

[0041] In the above embodiment, the chute 11 can be manually pushed to move on the first track 13 and the second track 14. In other embodiments, a driving mechanism for driving the chute 11 to reciprocate along the direction of the hydraulic trestle 10 can be provided on the bracket 12; during operation, the driving mechanism is used to drive the chute 11 to move on the first track 13 and the second track 14. The driving mechanism can be a linear drive such as a hydraulic cylinder, a pneumatic cylinder or an electric push rod, or a screw drive mechanism, a chain drive mechanism, etc.

[0042] In some embodiments, see Figure 1 , the first track 13 is connected to the bracket 12 through a lifting assembly. The height of the first track 13 can be adjusted by the lifting assembly, thereby achieving the purpose of adjusting the height difference between the first track 13 and the second track 14. Exemplarily, the lifting assembly includes a telescopic rod 15 with a locking function, one end of the telescopic rod 15 is connected to the bracket 12, and the other end of the telescopic rod 15 is connected to the first track 13. During operation, the height of the first track 13 is adjusted by extending or shortening the telescopic rod 15. Among them, the number of telescopic rods 15 can be two, and the two telescopic rods 15 are respectively arranged at the two ends of the first track 13. In other embodiments, the lifting assembly can also be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc.

[0043] The telescopic rod 15 may be a multi-section telescopic structure. In some embodiments, the telescopic rod 15 is a two-section telescopic structure. Figure 4The telescopic rod 15 includes a fixed tube 151, a movable rod 152 and a locking pin 153. The fixed tube 151 is provided with a first through hole for the locking pin 153 to pass through. The movable rod 152 is provided with a plurality of second through holes for the locking pin 153 to pass through from top to bottom. The lower end of the movable rod 152 is slidably fitted in the inner cavity of the fixed tube 151. The upper end of the movable rod 152 is connected to the first track 13. The locking pin 153 passes through the first through hole and the second through hole in sequence. The fixed tube 151 is used to be fixedly connected to the bracket 12, and the movable rod 152 is used to be connected to the first track 13. When it is necessary to adjust the length of the telescopic rod 15, the locking pin 153 is firstly pulled out from the first through hole and the second through hole, and then the position of the movable rod 152 is adjusted so that the second through hole at other positions on the movable rod 152 is aligned with the first through hole on the fixed tube 151, and then the locking pin 153 is inserted into the first through hole and the second through hole in sequence, so that the adjustment of the length of the telescopic rod 15 is completed.

[0044] In some embodiments, the second rail 14 may be fixedly connected to the bracket 12 by fasteners such as bolts. In other embodiments, the second rail 14 may also be connected to the bracket 12 by a lifting mechanism, so that the installation height of the second rail 14 is adjustable. When the installation height of the second rail 14 is adjustable, the first rail 13 may be connected to the bracket 12 by a lifting assembly, so that the installation height of the first rail 13 is adjustable, or may be fixedly connected to the bracket 12 by fasteners such as bolts, so that the installation height of the first rail 13 is not adjustable.

[0045] In order to reduce the friction resistance between the chute 11 and the track when moving, in some embodiments, see Figure 1 A first roller assembly 16 rolling with the first track 13 is provided below the chute 11, and a second roller assembly 17 rolling with the second track 14 is provided below the chute 11. When the chute 11 is moving, the first roller assembly 16 rolls on the first track 13, and the second roller assembly 17 rolls on the second track 14, which reduces the friction resistance between the chute 11 and the track during movement, thereby achieving the purpose of labor saving.

[0046] For example, see Figure 5 The outer surface of the first track 13 is a cylindrical surface; the first roller assembly 16 includes a first mounting beam 161 mounted at the bottom of the chute 11, and at least two first rollers 162 mounted below the first mounting beam 161 and rotating around their own axes. The outer circumference of the first roller 162 is provided with a first concave surface 163 that matches the first track 13. The first concave surface 163 matches the first track 13, so that the first roller 162 can not only roll on the first track 13, but also prevent the first roller 162 from derailing during the rolling process. Figure 6The outer surface of the second track 14 is a cylindrical surface; the second roller assembly 17 includes a second mounting beam 171 mounted at the bottom of the chute 11, and at least two second rollers 172 mounted below the second mounting beam 171 and rotating around their own axes. The outer circumference of the second roller 172 is provided with a second concave surface 173 that matches the second track 14. The second concave surface 173 matches the second track 14, so that the second roller 172 can not only roll on the second track 14, but also prevent the second roller 172 from derailing during the rolling process.

[0047] When the height of the first track 13 is adjusted by the lifting assembly, the lifting direction of the lifting assembly can be set so that the straight-line distance between the first track 13 and the second track 14 remains unchanged, or the straight-line distance between the first track 13 and the second track 14 changes.

[0048] Exemplarily, when the lifting assembly drives the first track 13 to move in the vertical direction to adjust the height of the first track 13, the linear distance between the first track 13 and the second track 14 changes; in order to ensure that the first roller assembly 16 and the second roller assembly 17 always cooperate with the first track 13 and the second track 14, the distance between the first roller assembly 16 and the second roller assembly 17 is adjustable. For example, the first roller assembly 16 is connected to the chute 11 by fasteners such as bolts, and the second roller assembly 17 is movably connected to the chute 11 and can move closer to or away from the first roller assembly 16; or the second roller assembly 17 is connected to the chute 11 by fasteners such as bolts, and the first roller assembly 16 is movably connected to the chute 11 and can move closer to or away from the second roller assembly 17.

[0049] In some embodiments, see Figure 2 The support 12 includes two tripods 121 arranged at intervals along the direction of the hydraulic trestle 10 and a longitudinal connecting rod 122 connected between the two tripods 121. The tripod 121 is used to connect with the hydraulic trestle 10. The first track 13 and the second track 14 are respectively arranged on the two tripods 121 at both ends.

[0050] In some embodiments, see Figure 3, the longitudinal connecting rods 122 include three, and the three longitudinal connecting rods 122 are respectively arranged at the three vertices of the tripod 121. The tripod 121 includes a vertically arranged upright pole 1211, a horizontally arranged cross bar 1212, and an obliquely arranged diagonal rod 1213. The upright pole 1211 is used to connect with the hydraulic trestle 10, the upper end of the upright pole 1211 is connected to the upper end of the diagonal rod 1213, one end of the cross bar 1212 is connected to the lower end of the upright pole 1211, and the other end of the cross bar 1212 is connected to the lower end of the diagonal rod 1213. The upright pole 1211, the cross bar 1212 and the diagonal rod 1213 are connected to form a right-angled triangle tripod 121. The upright pole 1211, the cross bar 1212, the diagonal rod 1213, and the longitudinal connecting rod 122 are all made of steel pipes. Among them, the upright pole 1211 can also be used as a fixed pipe 151.

[0051] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Based on the technical essence of the present application and within the spirit and principles of the present application, any simple modification, equivalent replacement and improvement of the above embodiments shall still fall within the protection scope of the technical solution of the present application.
