Description

Technical Field

[0001] The utility model relates to the field of construction equipment, in particular to a switch valve device for a concrete placing machine pump pipe outlet and the concrete placing machine. Background Art

[0002] During the process of pumping concrete pouring, the concrete grades of walls, columns and beams and slabs are often not the same. The strength grade of wall and column concrete is generally higher than that of beam and slab concrete. The order of pouring concrete is wall and column concrete first and then beam and slab concrete. When pouring wall and column concrete, the pump pipe needs to be moved frequently.

[0003] In the past, when moving the concrete placing machine pump pipe at a construction site, the pump pipe outlet was often sealed with a duct bag or not sealed. If it was not sealed or was not sealed firmly, it would easily cause concrete to fall onto the board surface or beam groove, thereby forming cold joints and resulting in poor appearance of concrete forming. Therefore, it is necessary to set a valve device at the pump pipe outlet to control the opening and closing of the outlet. Utility Model Content

[0042] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0043] like Figure 1 As shown in FIG, a switch valve device for a pump pipe outlet of a material placing machine provided by an embodiment of the present invention comprises a sleeve 1, a connector 2, a fastener 3 and a cover plate 4. The sleeve 1 is used to be sleeved at the pump pipe outlet of the material placing machine. The connector 2 and the fastener 3 are used to connect and fasten the sleeve 1 to the pump pipe 30 (refer to FIG. Figure 5 The cover plate 4 is reversibly arranged on the sleeve 1 to open or close the pump pipe outlet of the material placing machine.

[0044] Specifically, in this embodiment, Figure 1 As shown, the sleeve 1 includes a first sleeve 11 and a second sleeve 12. Both the first sleeve 11 and the second sleeve 12 are semicircular sleeves with preset dimensions to match the diameter of the concrete placing machine's pump pipe. The first sleeve 11 and the second sleeve 12 each have a connecting end 101 and a fastening end 102. During use, the first sleeve 11 and the second sleeve 12 are spliced together to form a ring, and the connecting end of the first sleeve 11 is aligned with the connecting end of the second sleeve 12, and the fastening end of the first sleeve 11 is aligned with the fastening end of the second sleeve 11. This allows the ring-shaped sleeve 1 to be installed as a whole at the pump pipe outlet of the concrete placing machine. It will be appreciated that in this embodiment, the sleeve 1 is a split structure that is installed at the pump pipe outlet of the concrete placing machine by splicing, which improves the convenience of sleeve 1 installation.

[0045] Furthermore, preferably, friction lines 103 are formed on the inner walls of both the first sleeve 11 and the second sleeve 12 to increase the surface friction coefficient of the inner walls of the first sleeve 11 and the second sleeve 12. Thus, when the sleeve 1 is sleeved onto the outside of the pump tube, the friction between the inner surface of the sleeve 1 and the outer surface of the pump tube can be increased, thereby facilitating improved stability of the connection between the sleeve 1 and the pump tube.

[0046] like Figure 2As shown, in this embodiment, the connecting member 2 is connected between the connecting ends of the first sleeve 11 and the second sleeve 12. Specifically, the connecting member 2 is a fixed connecting member. The first end of the fixed connecting member 2 is connected to the connecting end 101 of the first sleeve 11 through the first bolt 21, and the second end of the fixed connecting member 2 is connected to the connecting end 101 of the second sleeve 12 through the second bolt 22. It can be understood that the connecting ends 101 of the first sleeve 11 and the second sleeve 12 can be fixedly connected through the fixed connecting member 2 to ensure the stability of the connection.

[0047] Moreover, in the above embodiment, preferably, the fixed connecting member 2 is an arc-shaped plate. The arc-shaped plate has a preset elastic activity range, so that the connecting ends of the first sleeve 11 and the second sleeve 12 can elastically move within the preset elastic activity range, thereby being able to adapt to the size change of the pump pipe within a certain range and further improving the convenience of installing the sleeve 1.

[0048] In another embodiment, the connecting member 2 can also be a movable connecting member. When specifically connecting, the movable connecting member 2 is hinged between the connecting ends of the first sleeve 11 and the second sleeve 12, so that the first sleeve 11 can rotate relative to the second sleeve 12 around the axial direction of the sleeve 1. It can be understood that when the movable connecting member 2 is adopted, the splicing of the first sleeve 11 and the second sleeve 12 is realized by flipping; when the fixed connecting member 2 is adopted, the splicing of the first sleeve 11 and the second sleeve 12 is realized by translational alignment, and the specific use can be adaptively selected according to needs.

[0049] As Figure 3 shown, in this embodiment, the fastener 3 is connected to the fastening ends of the first sleeve 11 and the second sleeve 12 to limit the axial movement of the sleeve 1 and the pump pipe. Specifically, the fastener 3 includes a connecting block 31 and an adjusting handle 32. The connecting block 31 is connected to the fastening ends of the first sleeve 11 and the second sleeve 12, and the adjusting handle 32 is threadedly connected to the connecting block 31 to drive the fastening ends of the first sleeve 11 and the second sleeve 12 to approach or move away from each other by screwing the adjusting handle 32. It can be understood that when the fastening ends of the first sleeve 11 and the second sleeve 12 approach each other, the sleeve 1 can be stably sleeved outside the pump pipe 30; when the fastening ends of the first sleeve 11 and the second sleeve 12 move away from each other, the sleeve 1 can move along the outside of the pump pipe 30.

[0050] As Figure 4As shown in the figure, in this embodiment, the cover plate 4 is rotatably arranged on the sleeve 1 around the radial direction of the sleeve 1 to switch between a closed state and an open state. It can be understood that when the cover plate 4 is opened, the pump pipe outlet is opened, and at this time, the reinforced concrete can be conveyed; when the cover plate 4 is closed, the pump pipe outlet is closed, and at this time, the pump pipe can be transported. Specifically, in this embodiment, the cover plate 4 is hinged to the connecting ear plate 13 of the sleeve 1 through the movable rod 41, so that the cover plate 4 is rotatably installed on the sleeve 1.

[0051] Moreover, preferably, a first locking member 42 (for example: a buckle) is provided on the cover plate 4. Correspondingly, a second locking member 14 (for example: a clamping groove) is provided on the outer wall of the sleeve 1. When the cover plate 4 is closed, the first locking member 42 is engaged with the second locking member 14, thereby restricting the relative position of the cover plate 4 and the sleeve 1 to achieve the sealing of the pump pipe outlet. When the cover plate 4 is opened, the first locking member 42 is separated from the second locking member 14, thereby releasing the position restriction of the cover plate 4 and the sleeve 1, so that the pump pipe can normally convey the reinforced concrete.

[0052] In addition, as Figure 1 shown, in the above embodiment, preferably, a sealing ring 43 is provided on the surface of the cover plate 4 facing the sleeve 1 to block the gap between the cover plate 4 and the sleeve 1, thereby improving the sealing effect of the pump pipe outlet and avoiding the leakage of the reinforced concrete.

[0053] As Figure 5 shown, the embodiment of the present invention further provides a distributing machine, which includes a frame 10, a distributor 20, a pump pipe 30 and the switch valve device 40 in the above embodiment. Among them, the frame 10 is placed on the working surface. The distributor 20 is arranged on the frame 10 to provide power for the conveyance of the reinforced concrete. The pump pipe 30 is connected to the power output end of the distributor 20 to convey the reinforced concrete. The switch valve device 40 is sleeved on the pump pipe 30 to close or open the outlet of the pump pipe 30.

[0054] In summary, the switch valve device for the pump pipe outlet of the distributing machine and the distributing machine provided by the embodiment of the present invention have the following beneficial effects:

[0055] (1) The switch valve device in this embodiment can temporarily seal the opening of the pump pipe when the pump pipe needs to be moved, preventing the residual high-strength reinforced concrete from falling onto the beam and slab when the pump pipe is moved, thereby avoiding the phenomenon of concrete mixing and saving materials.

[0056] (2) The connecting member 2 can be set as a fixed connecting member or a movable connecting member to adapt to different safety requirements. And when the fixed connecting member 2 can be set as an arc-shaped plate, so that the connecting end of the first sleeve and the second sleeve can elastically move within a certain range.

[0057] (3) A sealing ring is provided on the inner surface of the cover plate 4, and cooperates with the first locking member and the second locking member to improve the sealing effect of the pump pipe outlet.

[0058] (4) The inner walls of the first sleeve 11 and the second sleeve 12 are provided with friction lines 103 to increase the surface friction coefficient of the inner walls of the first sleeve 11 and the second sleeve 12, thereby facilitating the improvement of the stability of the connection between the sleeve 1 and the pump tube.
