Detailed Description

For a clearer understanding of the features, aspects and advantages of the present invention, and the advantages achieved thereby, the present invention will now be described in more detail with reference to the accompanying drawings, which are presented in the form of examples, but are intended to be illustrative and supplementary in nature, and therefore should not be construed as limiting the scope of the invention as defined in the appended claims.

Please refer to fig. 1, which is a schematic diagram of a concrete pumping and transporting device 1 according to a first preferred embodiment of the present invention. The concrete pumping and conveying device 1 comprises a concrete conveying device 10, a driving mechanism 11, an output pipe 14, an output switching device 15 and a containing device 16.

The driving mechanism 11 includes a gas storage device 110, a third pipe 111, a fourth pipe 112, a first input switch 113, and a second input switch 114. The gas storage device 110 is a positive pressure gas storage device to press the gas stored inside the gas storage device 110 toward the third pipe body 111 or the fourth pipe body 112. In other embodiments of the present invention, the air storage device 110 may include a silent air compressor (not shown).

The third tube 111 is provided with a first front-end input hole 1110 at its front end 1113 and a first rear-end input hole 1111 at its rear end 1114. The first input switch 113 switchably connects the gas storage device 110 to the first front end input hole 1110 or the first rear end input hole 1111 of the third pipe body 111, so that the first piston 1112 can reciprocate between the front end 1113 (i.e., the second position of the first piston 1112) and the rear end 1114 (i.e., the first position of the first piston 1112) of the third pipe body 111. For example: when the first input switch 113 controls the gas storage device 110 to communicate with the first rear end input hole 1111 of the third pipe body 111, the first piston 1112 is driven to move in the first direction D1; in contrast, when the first input switch 113 controls the gas storage device 110 to communicate with the first front input hole 1110 of the third tube 111, the first piston 1112 is driven to move in the second direction D2, and the first direction D1 is opposite to the second direction D2.

The fourth pipe 112 is provided with a second front-end input hole 1120 at a front end 1123 thereof and a second rear-end input hole 1121 at a rear end 1124 thereof. The second input switch 114 switchably communicates the gas storage device 110 with the second front end input hole 1120 or the second rear end input hole 1121 of the fourth pipe body 112, so that the second piston 1122 can reciprocate between the front end 1123 (i.e., the second position of the second piston 1122) and the rear end 1124 (i.e., the first position of the second piston 1122) of the fourth pipe body 112. For example: when the second input switch 114 controls the gas storage device 110 to communicate with the second front end input hole 1120 of the fourth pipe 112, the second piston 1122 is driven to move in the second direction D2; similarly, when the second input switch 114 controls the gas storage device 110 to communicate with the second rear end input hole 1121 of the fourth pipe body 112, the second piston 1122 is driven to move in the first direction D1. In addition, an operator may control the switching operation of the first input switch 113 and the second input switch 114 via a control circuit (not shown) such that the first piston 1112 and the second piston 1122 move in opposite directions (i.e., one moves in the direction D1 and the other moves in the direction D2, and vice versa). In other embodiments of the present invention, the switching of the first input switch 113 and the second input switch 114 is actuated using an electromagnetic switching valve.

The receiving device 16 includes a receiving space 160 therein for receiving concrete, and a top of the receiving device 16 may be opened so that the concrete is poured into the receiving space 160 from above. In one embodiment of the present invention, a filtering device (not shown) having a grill structure is provided at the top of the receiving device 16. One end of the delivery pipe 14 is connected to the receiving means 160 and the other end can be connected to the area to be poured (not shown).

The concrete conveying apparatus 10 includes a first pipe body 12 and a second pipe body 13. The first tube 12 has a first push member 120 therein, the first push member 120 being reciprocally movable in an axial direction between a rear end 122 (i.e., a first position of the first push member 120) and a front end 121 (i.e., a second position of the first push member 120) of the first tube 12. The front end 121 of the first tube 12 is connected to the accommodating device 16, and the rear end 122 of the first tube 12 is connected to the third tube 111 of the driving mechanism 11 via the connecting member 18. Since the first tube 12 is in communication with the third tube 111, when the first piston 1112 in the third tube 111 is driven, the first pushing member 120 in the first tube 12 is driven to move in the same direction.

The second tube body 13 has a second pushing member 130 therein. The second pushing member 130 is reciprocally movable in the axial direction between a rear end 132 (i.e., a first position of the second pushing member 130) and a front end 131 (i.e., a second position of the second pushing member 130) of the second tube body 13. The front end 131 of the second tube 13 is connected to the accommodating device 16, and the rear end 132 of the second tube 13 is connected to the fourth tube 112 of the driving mechanism 11 via the connecting member 18. Since the second tube 13 is in communication with the fourth tube 112, the second pushing member 130 in the second tube 13 is driven to move in the same direction when the second piston 1122 in the fourth tube 112 is driven. In other embodiments of the present invention, the third tube 111 may be directly connected to the first tube 12, and the fourth tube 112 may be directly connected to the second tube 13.

The first input switch 113 and the second input switch 114 have an air flow regulating valve (not shown) therein, and the air flow regulating valve of the first input switch 113 can regulate the air flow of the air storage device 110 to the first front end input hole 1110 and the first rear end input hole 1111 of the third pipe body 111, regulate the moving rate of the first piston 1112 in the third pipe body 111, and thereby regulate the moving rate of the first pushing member 120 in the first pipe body 12. Also, the air flow regulating valve of the second input switch 114 may regulate the amount of air flow of the air storage device 110 to the second front end input hole 1120 and the second rear end input hole 1121 of the fourth pipe 112, regulate the moving rate of the second piston 1122 in the fourth pipe 112, and thereby regulate the moving rate of the second pushing member 130 in the second pipe 13.

Please refer to fig. 2A to 2D. The output switching device 15 includes a rotating member 151 and a switching tube 152. The output switching device 15 switchably connects the first pipe body 12 or the second pipe body 13 to the output pipe body 14. The switching tube 152 is substantially curved, and the first end 1521 and the second end 1522 of the switching tube 152 have a first connection portion 1523 and a second connection portion 1524, respectively, and are sleeved on the rotating member 151. The first connection portion 1523 is spaced apart from the second connection portion 1524 by a predetermined distance, improving stability when the rotation member 151 drives the switching tube 152 to rotate. The first end 1521 of the switching tube 152 is connected to the output tube 14, and the second end 1522 of the switching tube 152 is switchably connected to the first tube 12 through the first through hole 161 of the accommodating device 16 or to the second tube 13 through the second through hole 162 of the accommodating device 16 by driving the rotating member 151.

The rotation member 151 is driven by the first telescopic rod 153, the second telescopic rod 154, and the swinging member 155, so that the second end 1522 of the switching tube 152 can be switched between the first tube 12 and the second tube 13. First end 1531 of first telescoping rod 153 is pivotally connected to receiving device 16 and second end 1532 of first telescoping rod 153 is pivotally connected to one side of upper end 1551 of oscillating member 155. The first end 1541 of the second telescoping rod 154 is pivotally connected to the receiving means 16 and the second end 1542 of the second telescoping rod 154 is pivotally connected to the opposite side of the upper end 1551 of the oscillating member 155, the rotating member 151 being connected to the lower end 1552 of the oscillating member 155 through the receiving means 16.

As shown in fig. 2A and 2B, when the first telescopic rod 153 is extended and the second telescopic rod 154 is contracted, the upper end 1551 of the swinging member 155 rotates along the first rotation direction R1, so as to drive the rotation member 151 to synchronously rotate along the first rotation direction R1 and drive the second end 1522 of the switching tube 152 to be connected to the first tube 12. In contrast, as shown in fig. 2C and 2D, when the first telescopic rod 153 is retracted and the second telescopic rod 154 is extended, the upper end 1551 of the swinging member 155 rotates along the second rotation direction R2, so as to drive the rotating member 151 to synchronously rotate along the second rotation direction R2 and drive the second end 1522 of the switching tube 152 to be connected to the second tube 13. As shown in fig. 2A, the second rotation direction R2 is opposite to the first rotation direction R1.

In order to reduce the abrasion between the switching tube 152 and the wall of the accommodating device 17 during rotation, a first collar 1525 is disposed at the junction between the first end 1521 of the switching tube 152 and the wall of the accommodating device 16 (see fig. 2C), and a second collar 1526 is disposed at the junction between the second end 1522 of the switching tube 152 and the wall of the accommodating device 16 (see fig. 2B), and the installation of the first collar 1525 and the second collar 1526 can further improve the adhesion between the switching tube 152 and the first tube 12, and between the second tube 13 and the output tube 14.

The operation mode of the concrete pumping and conveying device 1 comprises the following steps: as shown in fig. 2A, 2B and 3A, in the first operation step (a), the first telescopic rod 153 is operated to be in an extended state and the second telescopic rod 154 is operated to be in a contracted state, so that the first pipe body 12 is communicated with the output pipe body 14 through the switching pipe body 152, and the second pipe body 13 is communicated with the accommodating space 160 of the accommodating device 16.

In the second operation step (b), the first input switch 113 is controlled to enable the air storage device 110 to be communicated with the first rear end input hole 1111 of the third pipe body 111, so as to drive the first piston 1112 in the third pipe body 111 to move from the first position to the second position along the first direction D1, and further drive the first pushing member 120 in the first pipe body 12 to move from the first position to the second position along the first direction D1, so as to push the concrete in the first pipe body 12 to the output pipe body 14 through the switch pipe body 152. Meanwhile, the second input switch 114 is controlled to enable the air storage device 110 to be communicated with the second front end input hole 1120 of the fourth pipe body 112, so as to drive the second piston 1122 in the fourth pipe body 112 to move from the second position to the first position along the second direction D2, and further drive the second pushing member 130 in the second pipe body 13 to move from the second position to the first position along the second direction D2, so as to suck the concrete in the accommodating device 17 into the second pipe body 13.

Then, as shown in fig. 2C, 2D and 3B, in the third operation step (C), the first telescopic rod 153 is adjusted to be in a contracted state and the second telescopic rod 154 is adjusted to be in an extended state, so that the second pipe 13 is communicated with the output pipe 14 through the switching pipe 152, and the first pipe 12 is communicated with the accommodating space 160 of the accommodating device 16.

In the fourth operation step (D), the second input switch 114 is controlled to connect the air storage device 110 to the second rear end input hole 1121 of the fourth pipe 112, so as to drive the second piston 1122 in the fourth pipe 112 to move from the first position to the second position along the first direction D1, and further drive the second pushing member 130 in the second pipe 13 to move from the first position to the second position along the first direction D1, so as to press the concrete in the second pipe 12 to the output pipe 14 through the switch pipe 152. Meanwhile, the first input switch 113 is controlled to enable the air storage device 110 to be communicated with the first front end input hole 1110 of the third pipe body 111, so that the first piston 1112 in the third pipe body 111 is driven to move from the second position to the first position along the second direction D2, and the first pushing component 120 in the first pipe body 12 is driven to move from the second position to the first position along the second direction D2, so that concrete in the accommodating device 17 is sucked into the first pipe body 12. Finally, the fourth operation step (d) is followed by a return to the first operation step (a) to again perform the operation cycle (i.e., step (a), step (b), step (c), step (d)).

Please refer to fig. 4, which is a schematic diagram of a concrete pumping and transporting device 1' according to a second preferred embodiment of the present invention. In the second preferred embodiment, the same concrete transporting device 10, output pipe 14, output switching device 15, and housing device 16 as in the first preferred embodiment are used, but a different type of driving mechanism 11' is employed.

The driving mechanism 11 'includes a first air reservoir 115', a second air reservoir 116', and an input switch 117'. The first gas storage device 115' is a positive pressure gas storage device, and is configured to drive the first pushing member 120 to move from the rear end 122 of the first pipe body 12 (i.e. the first position of the first pushing member 120) to the front end 121 of the first pipe body 12 (i.e. the second position of the first pushing member 120) along the first direction D1; or the second pushing member 130 is pushed to move from the rear end 132 of the second tube body 13 (i.e., the first position of the second pushing member 130) toward the front end 131 of the second tube body 13 (i.e., the second position of the second pushing member 130) in the first direction D1.

The second gas storage device 116' is a negative pressure gas storage device, and is configured to drive the first pushing member 120 to move from the front end 121 of the first pipe body 12 (i.e. the second position of the first pushing member 120) to the rear end 122 of the first pushing member 120 (i.e. the first position of the first pushing member 120) along the second direction D2; or the second pushing member 130 is pushed to move from the front end 131 of the second tube body 13 (i.e., the second position of the second pushing member 130) toward the rear end 132 of the second tube body 13 (i.e., the first position of the second pushing member 130) in the second direction D2. As shown in fig. 4, the second direction D2 is opposite to the first direction D1.

The input switch 117' switchably communicates the first gas storage device 115' with one of the first pipe body 12 and the second pipe body 13 and switchably communicates the second gas storage device 116' with the other of the first pipe body 12 and the second pipe body 13. That is, when the input switch 117' is controlled such that the first gas storage device 115' communicates with the first pipe body 12, then the second gas storage device 116' communicates with the second pipe body 13; conversely, when the first gas storage device 115 'communicates with the second pipe body 13, the second gas storage device 116' communicates with the first pipe body 12. The input switch 117' is controlled such that the first pushing member 120 and the second pushing member 130 reciprocate between the first tube 12 and the second tube 13, respectively, and the first pushing member 120 and the second pushing member 130 move in opposite directions to each other. In other embodiments of the invention, the input switch 117' may be actuated using a solenoid-operated switching valve.

The operation mode of the concrete pumping and conveying device 1' in the second embodiment of the present invention includes the following steps: the first operating step (a') is substantially identical to step (a) described in the previous first embodiment; in the second operation step (B '), as shown in fig. 2A, 2B and 5A, the input switch 117' is controlled to connect the first air storage device 115' to the first pipe body 12, and the first pushing member 120 is driven to move from the first position to the second position along the first direction D1, so as to press the concrete in the first pipe body 12 to the output pipe body 14 through the switch pipe body 152. Meanwhile, the input switcher 117 'is controlled to enable the second air storage device 116' to be communicated with the second pipe body 13, and the second pushing component 130 is driven to move from the second position to the first position along the second direction D2 so as to suck the concrete in the accommodating device 17 into the second pipe body 13; the third operating step (c') is substantially identical to step (c) described in the previous first embodiment; and a fourth operation step (D '), as shown in fig. 2C, 2D and 5B, the input switch 117' is controlled to connect the first air storage device 115' to the second pipe body 13, and the second pushing member 130 is driven to move from the first position to the second position along the first direction D1, so as to press the concrete in the second pipe body 13 to the output pipe body 14 through the switch pipe body 152. Meanwhile, the input switch 117 'is controlled to enable the second air storage device 116' to be communicated with the first pipe body 12, and the first pushing component 120 is driven to move from the second position to the first position along the second direction D2 so as to suck the concrete in the accommodating device 17 into the first pipe body 12. Finally, after the fourth operating step (d '), the process returns to the first operating step (a') to perform the operating cycle again (i.e., step (a '), step (b'), step (c '), step (d')).

Please refer to fig. 6, which is a schematic diagram illustrating a concrete pumping and transporting device 1″ according to a third preferred embodiment of the present invention. In the third preferred embodiment, the same output pipe 14, output switching device 15 and housing device 16 as in the first and second preferred embodiments are used, but a different type of concrete conveying device 10″ and driving mechanism 11 "is employed.

The concrete conveying device 10 "includes a first pipe body 12" and a second pipe body 13". The drive mechanism 11 "includes a first linear motor 118" and a second linear motor 119". The front end 121 "of the first tube 12" is connected to the receiving means 16. The first tube 12 "contains therein a first pushing member 120" having a magnetic member. The first linear motor 118 "has a coil and surrounds the first tube 12" from a front end 121 "to a rear end 122" of the first tube 12 "to drive the first pushing member 120" to reciprocate between the front end 121 "(the first pushing member 120" is located at the second position) of the first tube 12 "and the rear end 122" (the first pushing member 120 "is located at the first position) of the first tube 12" in the axial direction.

The front end 131 "of the second tube 13" is connected to the receiving means 16 and contains a second pushing member 130 having a magnetic member therein. The second linear motor 119″ has a coil and surrounds the second tube 13″ from the front end 131' to the rear end 132″ of the second tube 13″ to drive the second pushing member 130″ to reciprocate between the front end 131 "(the second pushing member 130" is located at the second position) of the second tube 13″ and the rear end 132 "(the second pushing member 130" is located at the first position) of the second tube 13″ in the axial direction.

The first and second linear motors 118 "and 119" are controlled such that the first pushing member 120 "of the first tube 12" moves in an opposite direction to the second pushing member 130 "of the second tube 13". In one embodiment of the invention, the first tube 12 "rear end 122" and the second tube 13 "rear end 132" may be connected to the connecting member 18.
