Description

Technical Field

[0023] In order to explain the technical content and structural features of the present invention in detail, further description is given below in combination with the implementation modes and the accompanying drawings.

[0024] See also Figure 1 and Figure 2 The walking feeding vehicle 100 for concrete pipe pile production of the present invention is used to transfer the mixed concrete at the concrete mixing plant (also called concrete mixing station) to the pipe mold 200, and also feed the transferred concrete into the pipe mold 200, so as to form concrete pipe piles by the pipe mold 200. For example, in Figure 1 In the present invention, the walking feeding vehicle 100 for concrete pipe pile production moves along the length direction of the pipe mold 200 during the concrete pipe pile production process to ensure uniform feeding of materials at various locations of the pipe mold 200, but the present invention is not limited thereto. It is understandable that since the walking feeding vehicle 100 for concrete pipe pile production of the present invention needs to move, a walking wheel 80 is installed at the bottom of the walking frame 10 described below, and the state is shown in FIG. Figure 1 and Figure 2 shown.

[0025] Among them, Figure 1 and Figure 2 As shown, the walking feeding vehicle 100 for concrete pipe pile production of the present invention comprises a walking frame 10, a suspension frame 20, a lifting and lowering driver 30, a storage hopper 40, a feeding hopper 50, a lifting mechanism 60, and a gate mechanism 70 for opening or closing the outlet of the storage hopper 40. The storage hopper 40 is inserted into the walking frame 10 in a lifting manner so that the storage hopper 40 can be lifted and lowered relative to the walking frame 10, thereby flexibly adjusting the height position of the storage hopper 40 relative to the walking frame 10. The gate mechanism 70 is installed on the storage hopper 40 so that the gate mechanism 70 can be lifted and lowered together with the storage hopper 40. The feeding hopper 50 is suspended directly below the storage hopper 40 so that the concrete in the storage hopper 40 can slide into the feeding hopper 50. The suspension frame 20 is located in the walking frame 10 and is assembled and connected with the feeding hopper 50 so that the feeding hopper 50 is fixed to the suspension frame 20, so that the feeding hopper 50 can be lifted and lowered together with the suspension frame 20. The lifting and placing driver 30 is located beside the storage hopper 40 and the feeding hopper 50. The lifting and placing driver 30 is installed on the walking frame 10 and the suspension frame 20. The lifting and placing driver 30 drives the suspension frame 20 to perform lifting movements close to or away from the storage hopper 40. Therefore, during the lifting and lowering movement of the suspension frame 20, the moving suspension frame 20 drives the feeding hopper 50 to perform lifting movements close to or away from the storage hopper 40, so as to meet the purpose of the feeding hopper 50 quickly approaching or moving away from the tube mold 200. The lifting mechanism 60 is located beside the storage hopper 40. The lifting mechanism 60 is installed on the walking frame 10 and the storage hopper 40 to drive the storage hopper 40 to perform lifting movements close to or away from the feeding hopper 50. Specifically, the lifting and placing driver 30 is respectively arranged beside the two opposite sides of the storage hopper 40, for example Figure 1Beside the first side 40a and the fourth side 40d of the middle storage hopper 40, the lifting and placing driver 30 is a cylinder, the piston rod 31 of the cylinder is arranged downward and is hinged to the suspension frame 20, and the cylinder body 32 of the cylinder is hinged to the walking frame 10. This design can increase the stability and reliability of the lifting and placing driver 30 to lift the suspension frame 20. More specifically, as follows:

[0026] like Figures 1 to 4As shown, the lifting mechanism 60 includes a motor 60a and an intermediate transmission assembly 60b that drives the storage hopper 40 to perform lifting motion under the drive of the motor 60a, so that the storage hopper 40 can be smoothly lifted and lowered by the cooperation of the motor 60a and the intermediate transmission assembly 60b, thereby reducing the amount of power used. Specifically, the intermediate transmission assembly 60b includes a reducer 61, a first transverse shaft 62, a second transverse shaft 63, a first longitudinal shaft 64, a second longitudinal shaft 65, a first commutator 66, a second commutator 67, a first worm gear device 68 and a second worm gear device 69. The reducer 61 is located beside the first side 40a of the storage hopper 40 and is installed on the walking frame 10, and the walking frame 10 provides support and fixing for the reducer 61; the reducer 61 has an input end and two output ends 612 arranged in a "cross" shape with the input end, and the two output ends 612 are oriented in opposite directions. The first longitudinal axis 64 is located beside the second side 40b of the storage hopper 40 adjacent to the first side 40a, and the second longitudinal axis 65 is located beside the third side 40c of the storage hopper 40 adjacent to the first side 40a, so that the first longitudinal axis 64 and the second longitudinal axis 65 are parallel to each other. The first end of the first transverse axis 62 is assembled and connected with an output end 612, and the second end of the first transverse axis 62 is spaced and docked with the first end of the first longitudinal axis 64. The first end of the second transverse axis 63 is assembled and connected with the other output end 612, and the second end of the second transverse axis 63 is spaced and docked with the first end of the second longitudinal axis 65. The first commutator 67 is installed at the position of the walking frame 10 between the first transverse axis 62 and the first longitudinal axis 64, and the walking frame 10 provides support and fixing for the first commutator 67; the second end of the first transverse axis 62 and the first end of the first longitudinal axis 64 are simultaneously inserted into the first commutator 67, so that under the action of the first commutator 67, the rotating first transverse axis 62 can drive the first longitudinal axis 64 to rotate synchronously. The second commutator 68 is installed on the traveling frame 10 at a position between the second transverse axis 63 and the second longitudinal axis 65, and the traveling frame 10 provides support and fixation for the second commutator 68; the second end of the second transverse axis 63 and the first end of the second longitudinal axis 65 are simultaneously inserted into the second commutator 68, so that under the action of the second commutator 68, the rotating second transverse axis 63 can drive the second longitudinal axis 65 to rotate synchronously. The housing 681 in the first worm gear device 68 is installed on the traveling frame 10, and the traveling frame 10 provides support and fixation for the first worm gear device 68; the first longitudinal axis 64 passes through the housing 681 in the first worm gear device 68 and is assembled and connected with the worm in the first worm gear device 68, and the worm 682 in the first worm gear device 68 is arranged vertically and assembled and connected with the storage hopper 40.The housing 691 of the second worm gear device 69 is installed on the walking frame 10, and the walking frame 10 provides support and fixing for the second worm gear device 69; the second longitudinal shaft 65 passes through the housing 691 of the second worm gear device 69 and is assembled and connected with the worm wheel in the second worm gear device 69; the worm 692 in the second worm gear device 69 is arranged vertically and assembled and connected with the storage hopper 40. The motor 60a is assembled and connected with the input end of the reducer 61. Therefore, under the operation of the motor 60a, the two output ends 612 of the reducer 61 can simultaneously drive the first transverse shaft 62 and the second transverse shaft 63 to rotate synchronously and coordinately; while the rotating first transverse shaft 62 drives the first longitudinal shaft 64 to rotate synchronously through the first commutator 67, the rotating second transverse shaft 63 drives the second longitudinal shaft 65 to rotate synchronously through the second commutator 68; and during the rotation of the first longitudinal shaft 64 and the second longitudinal shaft 65, the rotation of the first longitudinal shaft 64 drives the first longitudinal shaft 64 to rotate synchronously through the worm wheel in the first worm gear device 68. The worm 682 in the worm gear device 68 rises and falls, and at the same time, the rotation of the second longitudinal shaft 65 drives the worm 692 in the second worm gear device 69 to rise and fall through the worm wheel in the second worm gear device 69, thereby achieving smooth and precise lifting and lowering of the storage hopper 40 with the help of a motor 60a and an intermediate transmission assembly 60b, and can flexibly stay in any lifting position; at the same time, the above-mentioned structure and position of the intermediate transmission assembly 60b make the arrangement of the intermediate transmission assembly 60b on the walking frame 10 more reasonable and compact. To further ensure the consistency and stability of the lifting of the storage hopper 40, the first worm gear device 68 is two and is spaced apart from each other along the axial direction of the first longitudinal axis 64, and the upper end of the worm 682 in the first worm gear device 68 is fixedly connected to the storage hopper 40, and the second worm gear device 69 is two and is spaced apart from each other along the axial direction of the second longitudinal axis 65, and the upper end of the worm 692 in the second worm gear device 69 is fixedly connected to the storage hopper 40; of course, the number of the first worm gear device 68 and the second worm gear device 69 can also be three, so it is not limited to this. It can be understood that the first commutator 67 and the second commutator 68 can be a pair of bevel gear structures, which are well known in the art; in addition, the lifting mechanism 60 can include at least two oil cylinders according to actual needs, so it is not repeated here.

[0027] like Figure 3 and Figure 4As shown, the gate mechanism 70 includes a linear drive 71 and a first arc gate 72 and a second arc gate 73 that cooperate with each other to open or close. The first arc gate 72 and the second arc gate 73 are located directly below the outlet of the storage hopper 40, and the end of the first arc gate 72 extends upward to form a first swing arm 721 arranged side by side with the side wall 41 of the storage hopper 40, and the first swing arm 721 is pivotally connected to the side wall 41 of the storage hopper 40, so that the first arc gate 72 can perform a pivoting motion relative to the storage hopper 40; the end of the second arc gate 73 extends upward to form a second swing arm 731 arranged side by side with the side wall 41 of the storage hopper 40, and the second swing arm 731 is pivotally connected to the side wall 41 of the storage hopper 40, so that the second arc gate 73 can perform a pivoting motion relative to the storage hopper 40. The linear drive 71 is located above the first arc gate 72 and the second arc gate 73. The output end of the linear drive 71 is arranged downward and is assembled and connected to the second arc gate 73. The linear drive 71 directly drives the second arc gate 73 to open or close the outlet of the storage hopper 40. Specifically, the gate mechanism 70 also includes a first mounting shaft 74, a second mounting shaft 75, a first gear 76 and a second gear 77; the first mounting shaft 74 is fixedly inserted into the first swing arm 721, so that the first mounting shaft 74 and the first swing arm 721 are fixed together; and the first end of the first mounting shaft 74 is rotatably installed at the side wall 41 of the storage hopper 40, so that the first arc gate 72 can pivot relative to the side wall 41 of the storage hopper 40 with the help of the first mounting shaft 74; the first gear 76 is sleeved on the second end of the first mounting shaft 74; the second mounting shaft 75 is fixedly inserted into the second swing arm 731, so that the second mounting shaft 75 and the second swing arm 731 are fixed together. 731 are fixed together; and the first end of the second mounting shaft 75 is rotatably mounted on the side wall 41 of the storage hopper 40, so that the second arc gate 73 can pivot relative to the side wall 41 of the storage hopper 40 by means of the second mounting shaft 75; the second gear 77 is sleeved on the second end of the second mounting shaft 75, and the second gear 77 is also meshed with the first gear 76 for transmission; the output end of the linear drive 71 is assembled and connected with the second arc gate 73; such a design can achieve the purpose of synchronously driving the first arc gate 72 and the second arc gate 73 to open or close the outlet of the storage hopper 40 by means of a linear drive 71, so the cost is low and the structure is more compact. For example, the linear drive 71 is a drive including a cylinder body 711 and a piston rod 712, such as but not limited to a pneumatic cylinder or a hydraulic cylinder, at this time, the piston rod 712 is arranged downward and hinged to the second arc gate 73, and the cylinder body 711 is hinged to the side wall 41 of the storage hopper 40, but not limited to this.It is understandable that, according to actual needs, the output end of the linear drive 71 can also be assembled and connected with the first arc gate 72; when the gate mechanism 70 does not include the first mounting shaft 74, the second mounting shaft 75, the first gear 76 and the second gear 77, the first arc gate 72 and the second arc gate 73 are each corresponding to a linear drive 71 to ensure that the output end of one linear drive 71 is assembled and connected with the first arc gate 72 while the output end of the other linear drive 71 is assembled and connected with the second arc gate 73, thereby ensuring the coordination of the first arc gate 72 and the second arc gate 73 in opening or closing the outlet of the storage hopper 40.

Therefore, when the piston rod 582 of the first power driver 58 extends relative to the cylinder body 581, the piston rod 582 drives the first embracing plate 54 to pivot downward around the first assembly axis 56 and approach the tube mold 200; when the piston rod 582 of the first power driver 58 retracts relative to the cylinder body 581, the piston rod 582 drives the first embracing plate 54 to pivot upward around the first assembly axis 56 and away from the tube mold 200. Similarly, when the piston rod 592 of the second power driver 59 extends relative to the cylinder body 591, the piston rod 592 drives the second embracing plate 55 to pivot downward around the second assembly axis 57 and approach the tube mold 200; when the piston rod 592 of the second power driver 59 retracts relative to the cylinder body 591, the piston rod 592 drives the second embracing plate 55 to pivot upward around the second assembly axis 57 and away from the tube mold 200.

[0029] In conjunction with the accompanying drawings, the working principle of the walking feeding vehicle 100 for concrete pipe pile production of the present invention is explained: before entering and exiting the concrete mixing plant, the lifting mechanism 60 drives the storage hopper 40 to descend into place to ensure that the walking feeding vehicle 100 for concrete pipe pile production of the present invention can normally enter and exit the concrete mixing plant; when the walking feeding vehicle 100 for concrete pipe pile production of the present invention walks to the vicinity of the pipe mold 200, the lifting mechanism 60 drives the storage hopper 40 to rise to a set position, and the splicing component 53 drives the first hopper part 51 and the second hopper part 52 to do a splicing movement, so that the first hopper part 51 and the second material part 52 are spliced ​​together; at the same time, the first power driver 58 drives the first embracing plate 54 downward to approach one side of the pipe mold 200, and the second power driver 59 drives the second embracing plate 55 downward to approach one side of the pipe mold 200; then, the gate mechanism 70 opens the outlet of the storage hopper 40, so that concrete passes through the feeding hopper 50 and is fed into the pipe mold 200. In the process of feeding concrete into the pipe mold 200, the walking feeding vehicle 100 for concrete pipe pile production of the present invention also walks along the length direction of the pipe mold 200 to ensure the uniformity of feeding at various locations of the pipe mold 200.

[0030] Compared with the prior art, since the suspension frame 20 is located inside the walking frame 10 and is connected to the feeding hopper 50, the lifting and placing driver 30 is located beside the storage hopper 40 and the feeding hopper 50, and the lifting and placing driver 30 is installed on the walking frame 10 and the suspension frame 20 to drive the suspension frame 20 to do a lifting movement close to or away from the storage hopper 40, and the lifting mechanism 60 is located beside the storage hopper 40, and the lifting mechanism 60 is installed on the walking frame 10 and the storage hopper 40 to drive the storage hopper 40 to do a lifting movement close to or away from the feeding hopper 50; therefore, before the walking feeding vehicle 100 for concrete pipe pile production of the present invention enters and exits the concrete mixing plant, the lifting mechanism 60 drives the storage hopper 40 to move closer to or away from the feeding hopper 50. The overall height of the walking feeding vehicle 100 for concrete pipe pile production of the present invention is lowered by descending in the direction close to the feeding hopper 50, so as to ensure that the walking feeding vehicle 100 for concrete pipe pile production of the present invention can normally enter and exit the concrete mixing plant, avoiding the need to modify the concrete mixing plant to ensure the density of the feeding of the pipe mold 200; and before feeding the pipe mold 200, the lifting mechanism 60 drives the storage hopper 40 to rise in the direction away from the feeding hopper 50 to increase the height position of the storage hopper 40, so that the concrete in the storage hopper 40 obtains greater potential energy, thereby making the walking feeding vehicle 100 for concrete pipe pile production of the present invention feed the pipe mold 200 more densely, so as to ensure the quality of the pipe piles.

[0031] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
