[0027] EMBODIMENT
[0028] Please refer to Figs. 1-3The utility model provides a kind of concrete main machine pressurization feeding system, including storage tank 001, feed pipe 002, pump pressure pipe 003, pump pressure assembly 004, support block 005, sleeve 006, displacement assembly 007, valve assembly 008, sliding chute 009, sliding block 010.
[0029] In the prior art, the pump pressure device of concrete is provided with a single feed pipe 002 with a feed port on the storage tank 001, two pump pressure pipes 003 and corresponding pump pressure assemblies 004, and a displacement structure is arranged to drive the pipe opening of the feed pipe 002 to reciprocate and dock between the pipe openings of the two pump pressure pipes 003.
[0030] When sufficient concrete is pumped into one of the pump pressure pipes 003 through the pump pressure assembly 004, the displacement structure drives the pipe opening of the feed pipe 002 to dock with the pipe opening of the pump pressure pipe 003, and then the pump pressure assembly 004 pumps the concrete into the feed pipe 002. At this time, the other pump pressure pipe 003 also pumps in sufficient concrete, and the displacement structure drives the pipe opening of the feed pipe 002 to move to the pipe opening of the other pump pressure pipe 003 to pump out the concrete. The above steps are repeated to realize the pump pressure of concrete.
[0031] Further, in the present embodiment, the number of feed pipe 002 pipe openings corresponding to the pump pressure pipe 003 is set, the displacement structure is removed, the position of the feed pipe 002 pipe opening is fixed, and the alternating pump pressure of multiple pump pressure pipes 003 and pump pressure assemblies 004 is realized to realize the uninterrupted pumping of concrete into the feed pipe 002.
[0032] Further, the storage tank 001 is fixedly provided with the feed pipe 002, the feed port of the feed pipe 002 is located at the bottom of the storage tank 001, and at least two feed ports are provided. The end of the feed pipe 002 penetrating out of the storage tank 001 is communicated with the discharge port to realize the conveying of concrete.
[0033] The other end of the storage tank 001 is fixedly provided with at least two pump pressure pipes 003 arranged oppositely, the pipe opening of the pump pressure pipe 003 is located in the storage tank 001, and the pipe opening of the pump pressure pipe 003 is coaxially corresponding to the feed port of the feed pipe 002. The end of the pump pressure pipe 003 away from the pipe opening is provided with a pump pressure assembly 004, and the pump pressure end is located in the pipe of the pump pressure pipe 003. The displacement of the pump pressure end drives the pump pressure pipe 003 to realize the pumping and pumping functions, and the pumping direction is consistent with the length direction of the pipeline.
[0034] It is worth mentioning that the end of the pump pressure pipe 003 away from the pipe opening is fixed on the support block 005, and the fixed end of the pump pressure assembly 004 is also fixedly arranged on the support block 005 to realize the supporting function.
[0035] The outer diameter of the feeding pipe 002 and the pump pressure pipe 003 is consistent, the two pipe openings are oppositely arranged, and a gap exists between the two pipe openings (the gap is located in the storage tank 001). The outer sliding sleeve of the two pipes is provided with a sleeve 006, the sleeve 006 is connected with the displacement end of a displacement assembly 007, the fixed end of the displacement assembly 007 is fixedly arranged on the storage tank 001, and the sleeve 006 slides along the length direction of the pipe.
[0036] Preferably, when the pump pressure pipe 003 pumps in the concrete, the displacement assembly 007 drives the sleeve 006 to slide outside the feeding pipe 002 and slide to the gap between the two pipe openings, and the gap is not blocked. At this time, due to the pumping of the pumping assembly 004 in the pump pressure pipe 003, the concrete in the storage tank 001 is pumped into the pump pressure pipe 003 through the gap. When a sufficient amount of concrete is pumped, the pump pressure pipe 003 starts to pump out the concrete. At this time, the displacement assembly 007 drives the sleeve 006 to slide outside the feeding pipe 002 and slide to the position of the gap between the two pipe openings, so as to cover and block the entire gap and seal it. Then, due to the pumping of the pumping assembly 004, the concrete in the pump pressure pipe 003 is pumped into the connected feeding pipe 002, so as to realize the pumping of the concrete.
[0037] It is worth noting that at least two displacement assemblies 007 are arranged on the cross section of the sleeve 006, and the displacement assemblies 007 are symmetrically distributed on both sides of the sleeve 006, so as to ensure that the sleeve 006 slides smoothly outside the feeding pipe 002 and will not be stuck due to the penetration of sand particles in the concrete.
[0038] Further, the valve assembly 008 is arranged in the pipe of the feeding pipe 002, and the valve assembly 008 is close to the feeding port. One valve assembly 008 is arranged corresponding to each feeding port.
[0039] Preferably, the valve assembly 008 is a baffle, the baffle slides through the feeding pipe 002, and is arranged to be inclined relative to the length direction of the pipe of the feeding pipe 002. The baffle is fixedly connected with a sliding block 010 at the outer end of the feeding pipe 002, the sliding block 010 is slidably arranged in the sliding groove 009 of the sleeve 006 at the end face, and the sliding direction of the sliding block 010 through the sliding groove 009 is perpendicular to the length direction of the pipe of the feeding pipe 002.
[0040] Preferably, the baffle slides on the feeding pipe 002 through the sliding of the sleeve 006. When the feeding pipe 002 at this position pumps in the concrete, the sleeve 006 slides to the gap position, the sleeve 006 drives the baffle connected with the sliding block 010 to move, the sliding block 010 slides to the sliding groove 009 outside the sleeve 006, so as to pull out the baffle from the feeding pipe 002, the baffle does not block the pipe of the feeding pipe 002, and the concrete pumped into the feeding pipe 002 is smoothly conveyed.
[0041] When the feed pipe 002 at this place is not pumped into concrete, but the pump pressure pipe 003 is pumped into concrete, the sleeve 006 slides away from the gap position, the sliding block 010 slides towards the sliding groove 009 on the inner side of the sleeve 006, thereby pushing the baffle to extend into the feed pipe 002, and the baffle gradually blocks the pipeline of the feed pipe 002, avoiding that the concrete in the feed pipe 002 is pumped out by the pump pressure pipe 003 when pumping concrete, so that the feed pipe 002 cannot transport concrete subsequently.
[0042] It is worth noting that the baffle provided on the feed pipe 002 can be provided with only one baffle on one side of the feed pipe 002, or two baffles symmetrically provided on both sides of the feed pipe 002, and both setting structures can constitute the valve assembly 008 for blocking.
[0043] In this embodiment, the working principle of the device for pumping concrete is as follows:
[0044] Before pumping and transporting concrete, the sleeve 006 blocks the gap between the two pipe openings, and the pumping ends of the pumping assembly 004 are in an extended state, and there is no concrete in the pump pressure pipe 003 and the feed pipe 002.
[0045] When pumping concrete, one of the sleeves 006 slides out of the gap, the gap is connected to the concrete in the storage tank 001, the pumping end of the pumping assembly 004 at this place starts to retract, the pump pressure pipe 003 generates pumping, and the concrete is pumped from the gap. At this time, the valve assembly 008 in the pipe opening of the feed pipe 002 at this place is in a closed state, avoiding that the pump pressure pipe 003 sucks air in the feed pipe 002, so that the pumping function is lost.
[0046] At this time, the other sleeve 006 and the pumping assembly 004 do not work.
[0047] When pumping concrete, the pump pressure pipe 003 which has pumped enough concrete extends through the pumping end of the pumping assembly 004, and the concrete is pumped out. At this time, the sleeve 006 at this place slides to the gap position to block the gap, and the pumped concrete is directly pumped into the feed pipe 002. At this time, the valve assembly 008 in the pipe opening of the feed pipe 002 at this place is in an open state with the sliding of the sleeve 006, and the concrete is transported into the feed pipe 002.
[0048] At this time, the other sleeve 006 and the pumping assembly 004 do not work.
[0049] When the concrete in one of the pump pressure pipes 003 is completely pumped into the feeding pipe 002, the sleeve 006, the pump pressure assembly 004 and the valve assembly 008 at the position start to reset, and the other pump pressure pipe 003 synchronously pumps the concrete at this time, and the two same structures alternately pump the concrete, so that the concrete in the feeding pipe 002 is continuously and stably fed.
[0050] In the embodiment, the pump pressure rate of the pump pressure assembly 004 is increased, the interval time when the concrete is pumped and sucked is reduced, more concrete is fed into the feeding pipe 002 in the same time, the concrete feeding pressure of the feeding pipe 002 is increased, and the concrete is fed to a higher construction environment.
[0051] In the embodiment, two or more feeding pipe openings 002, sleeves 006, pump pressure pipes 003 and corresponding driving assemblies are arranged, the pump pressure assembly 004 is arranged with a suitable pump pressure rate, more concrete is fed in the same time, and the concrete feeding pressure of the feeding pipe 002 is increased.
[0052] The embodiments of the utility model have been described in detail. In order to avoid shielding the concept of the utility model, some details known in the art are not described. According to the above description, those skilled in the art can understand how to implement the technical scheme of the utility model, and the scope of the utility model is defined by the appended claims.
