Description

Technical Field

[0001] The invention belongs to the technical field of civil engineering, in particular to a civil engineering concrete delivery pump device with an automatic cleaning function. Background Art

[0002] Civil engineering is a general term for the science and technology of building various engineering facilities, including various engineering facilities on the ground, underground and in water, as well as the materials, equipment used, and the survey, design, construction, maintenance and repair technologies carried out. During the construction of civil engineering projects, in order to improve the efficiency of concrete transportation and save manpower and time, it is usually necessary to use concrete pumps to transport concrete.

[0003] In scenarios such as high-rise buildings, large infrastructure, narrow urban buildings, and underground projects, concrete pumps can deliver concrete accurately and efficiently to hard-to-reach places, thereby ensuring the continuity and quality of construction. During transportation, the concrete is sucked in and pushed out through the movement of the piston and push rod of the concrete cylinder, and the continuous retreat and advancement of the piston realizes the continuous pumping function of the concrete pump.

[0004] However, in actual use, the concrete mixer will provide the delivery pump with concrete for transportation, and the concrete will be transported to the specified location through the pump pipe, thereby realizing the transportation function. However, concrete is a mixture of cement and stone sand. During transportation, the internal space of the pump pipe is narrow. If larger stones enter the pump pipe, it will cause blockage and damage the pump body, thereby affecting the pumping efficiency and equipment life. At present, in order to avoid blockage, a baffle plate is usually installed on the material frame to prevent large stones from entering. However, after the baffle plate isolates the stones, the stones with cement will accumulate on the baffle plate. If they are not cleaned in time, they will solidify, which will reduce the filtering function of the baffle plate. Therefore, it needs to be improved and optimized. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, the embodiment of the present invention provides a civil engineering concrete delivery pump device with an automatic cleaning function, including a delivery pump box 1 and a bracket 2, the delivery pump box 1 is fixedly installed on the top of the bracket 2, a radiator 3 is fixedly installed on the top of the delivery pump box 1, a heat dissipation hole 4 is opened on the front side of the delivery pump box 1, a hopper 5 is fixedly installed on the front side of the delivery pump box 1, and a material blocking baffle 13 is arranged inside the hopper 5;

[0031] A vibration groove 18 is provided on the right side of the inner wall of the hopper 5, and a vibration plate 19 is movably installed inside the vibration groove 18. One end of the vibration plate 19 and the inner wall of the vibration groove 18 are elastically connected by a reset spring 20, and the other end of the vibration plate 19 abuts against the right side wall of the material blocking partition 13. A rotating wheel 14 is rotatably installed on the right outer wall of the hopper 5, and a telescopic groove 21 is provided inside the rotating wheel 14. An impact head 22 is movably installed inside the telescopic groove 21, and one end of the impact head 22 and the inner wall of the telescopic groove 21 are elastically connected by a compression spring 23. The vibration groove 18 and the vibration plate 19 are rectangular in shape, and the impact head 22 located inside the vibration groove 18 abuts against the vibration plate 19 through the elastic potential energy of the compression spring 23.

[0032] When the device is used, concrete will pass through the baffle plate 13 and fall into the hopper 5. At this time, the delivery pump box 1 starts to operate to pump the concrete in the hopper 5 into the delivery pump box 1, and passes through the delivery pipe 8 through the discharge pipe 9, and is finally delivered to a suitable position by the connecting pipe 10. When the concrete is transported, the first motor 11 and the second motor 15 are operated. The operation of the first motor 11 drives the stirring blade 12 to rotate to perform stirring and turbulent operation to prevent the concrete from solidifying. The operation of the second motor 15 not only drives the stirring blade 12 to rotate through the driving wheel 16, but also drives the rotating wheel 14 to rotate through the setting of the synchronous belt 17. Due to the dome-shaped design on the left side of the impact head 22, when the rotating wheel 14 rotates, the impact head 22 will contact the vibration groove The inner walls of 18 abut against each other, so that the impact head 22 is stored in the telescopic groove 21. At this time, the vibration plate 19 is reset by the elastic potential energy of the reset spring 20, so that the left side of the vibration plate 19 and the rotating wheel 14 abut against each other. When the other two groups of telescopic grooves 21 rotate to the inside of the vibration groove 18, the impact head 22 is reset by the elastic potential energy of the compression spring 23, so that the impact head 22 hits the vibration plate 19. Further, the vibration plate 19 hits the material blocking partition 13, and the material blocking partition 13 will screen larger stones. The screened stones fall into the inside of the receiving plate 24 through the vibration and tilt of the material blocking partition 13, and finally fall into the inside of the receiving plate 24 through the guide plate 26 inside the receiving plate 24 to realize automatic cleaning, so as to prevent the material blocking partition 13 from being blocked and the stones from solidifying.

[0033] Through the operation of the second motor 15, the driving wheel 16 drives the stirring blade 12 to perform the turbulence operation while driving the rotating wheel 14 to rotate. When the rotating wheel 14 rotates, the impact head 22 will abut against the inner wall of the vibration groove 18, so that the impact head 22 is stored in the telescopic groove 21. As the rotating wheel 14 continues to rotate, the other two groups of telescopic grooves 21 enter the vibration groove 18, and the impact head 22 is reset by the elastic potential energy of the compression spring 23 to achieve vibration operation. Compared with the traditional device, this device can vibrate the material baffle 13 while stirring the concrete inside the hopper 5, so as to prevent the stones with concrete from accumulating and solidifying on the material baffle 13, thereby reducing the cleaning burden of the staff.

[0034] Among them, a discharge pipe 9 is arranged at the front side of the hopper 5, and a connecting pipe 10 is arranged at the front side of the discharge pipe 9, and the connecting pipe 10 is responsible for transporting concrete;

[0035] A first connecting block 28 is fixedly installed on the outer wall of the discharge pipe 9, and a second connecting block 30 is fixedly installed on the rear side of the connecting pipe 10. The second connecting block 30 and the first connecting block 28 are clamped with each other. A movable groove 31 is provided inside the second connecting block 30, and a mounting block 32 is movably installed inside the second connecting block 30. The bottom of the mounting block 32 and the movable groove 31 are elastically connected by a spring 33. A control groove 29 is provided inside the first connecting block 28. The control groove 29 and the movable groove 31 correspond in position. The top of the mounting block 32 penetrates into the control groove 29 to fix the first connecting block 28.

[0036] Before the transportation operation is required, the staff first aligns the second connecting block 30 on the outer wall of the connecting tube 10 and the first connecting block 28 on the outer wall of the discharge pipe 9, and then inserts the second connecting block 30 into the first connecting block 28. When the second connecting block 30 is inserted, the inclined surface of the mounting block 32 will abut against the first connecting block 28, so that the mounting block 32 is received in the movable groove 31, and the spring 33 is compressed at this time. Then the staff rotates the connecting tube 10, and when the movable groove 31 and the control groove 29 are aligned with each other, the mounting block 32 will pop up through the elastic potential energy of the spring 33, so that the mounting block 32 enters the control groove 29 to complete the fixation.

[0037] By docking the first connecting block 28 and the second connecting block 30, the mounting block 32 is received inside the mounting block 32 to complete the preliminary connection. When the connecting tube 10 is rotated to align the movable groove 31 and the control groove 29 with each other, the mounting block 32 will pop up upward by the elastic potential energy of the spring 33, so that the mounting block 32 enters the control groove 29 to complete the fixation. Compared with the traditional device, the device can quickly dock and fix the discharge pipe 9 and the connecting tube 10, and the disassembly of the connecting tube 10 can be completed by only pressing the mounting block 32, which makes the disassembly and assembly convenient and effectively reduces the workload.

[0038] Among them, a material receiving plate 24 is fixedly installed on the front side of the material blocking partition 13, the material blocking partition 13 is inclined, and bolts 25 are provided on the left and right sides of the material receiving plate 24. The material receiving plate 24 and the hopper 5 are fixedly connected by the bolts 25.

[0039] The baffle plate 13 will screen the larger stones. The screened stones will fall into the inside of the receiving plate 24 through the vibration and tilting of the baffle plate 13, and finally fall into the storage box 27 through the guide plate 26 inside the receiving plate 24 to be automatically cleaned, so as to prevent the baffle plate 13 from being blocked and the stones from solidifying. After the transportation is completed, the staff can rotate the two sets of bolts 25 to complete the disassembly of the receiving plate 24 and the baffle plate 13 together for easy storage.

[0040] Through the inclined design of the retaining baffle 13 and the guide plate 26, the stones will fall into the storage box 27 along the retaining baffle 13 and the guide plate 26. Compared with the traditional device, the device can realize the automatic collection of concrete stones, avoid the waste of concrete resources, and protect the construction environment. It is green and environmentally friendly, and it is easy to disassemble, which reduces the workload of the staff.

[0041] Among them, stirring blades 12 are rotatably installed on the left and right sides of the inner wall of the hopper 5, and a first motor 11 is fixedly installed on the left side wall of the hopper 5. The output shaft of the first motor 11 is fixedly connected to the left stirring blade 12.

[0042] By providing two sets of stirring blades 12 , the concrete inside the hopper 5 is disturbed.

[0043] Among them, a glasses plate 6 is fixedly installed on the inner wall of the hopper 5, a swing arm 7 is provided on the top of the glasses plate 6, a conveying pipe 8 is fixedly installed on one end of the swing arm 7, and a discharge pipe 9 is fixedly installed on the front side of the hopper 5, and the conveying pipe 8 and the discharge pipe 9 are rotatably connected.

[0044] The delivery pump box 1 starts to operate to pump the concrete in the hopper 5 into the delivery pump box 1 , and passes through the delivery pipe 8 through the discharge pipe 9 , and is finally delivered to a suitable position by the connecting pipe 10 .

[0045] Among them, a second motor 15 is fixedly installed on the right side wall of the hopper 5, and a driving wheel 16 is fixedly installed on the output shaft of the second motor 15. The driving wheel 16 is rotatably installed on the outer wall of the hopper 5. The driving wheel 16 and the rotating wheel 14 are connected by a synchronous belt 17, and one end of the driving wheel 16 is fixedly connected to the right stirring blade 12.

[0046] The operation of the second motor 15 drives the driving wheel 16 to rotate, and the driving wheel 16 drives the rotating wheel 14 to rotate through the synchronous belt 17. At the same time, the driving wheel 16 also drives the stirring blade 12 to rotate to perform the stirring operation.

[0047] The rear side of the mounting block 32 is provided with an inclined surface, and the inclined surface on the rear side of the mounting block 32 can abut against the inner wall of the first connecting block 28 .

[0048] After the transportation operation is completed, the staff presses down the inclined surface of the installation block 32 through the control groove 29 so that the installation block 32 is squeezed into the movable groove 31, and then the staff pulls out the connecting pipe 10 to complete the disassembly.

[0049] A guide plate 26 is fixedly installed inside the receiving plate 24 , and a storage box 27 is provided on the left side of the hopper 5 . The guide plate 26 is responsible for guiding the screened stones to the storage box 27 .

[0050] The screened stones fall into the inside of the receiving plate 24 through the vibration and tilt of the blocking baffle 13, and finally fall into the inside of the receiving plate 24 through the guide plate 26 to realize automatic cleaning, thereby preventing the blocking baffle 13 from being blocked and the stones from solidifying.

[0051] Working principle and usage process:

[0052] When the device is used, concrete will pass through the baffle plate 13 and fall into the hopper 5. At this time, the delivery pump box 1 starts to operate to pump the concrete in the hopper 5 into the delivery pump box 1, and passes through the delivery pipe 8 through the discharge pipe 9, and is finally delivered to a suitable position by the connecting pipe 10. When the concrete is transported, the first motor 11 and the second motor 15 are operated. The operation of the first motor 11 drives the stirring blade 12 to rotate to perform stirring and turbulent operation to prevent the concrete from solidifying. The operation of the second motor 15 not only drives the stirring blade 12 to rotate through the driving wheel 16, but also drives the rotating wheel 14 to rotate through the setting of the synchronous belt 17. Due to the dome-shaped design on the left side of the impact head 22, when the rotating wheel 14 rotates, the impact head 22 will contact the vibration groove The inner walls of 18 abut against each other, so that the impact head 22 is stored in the telescopic groove 21. At this time, the vibration plate 19 is reset by the elastic potential energy of the reset spring 20, so that the left side of the vibration plate 19 and the rotating wheel 14 abut against each other. When the other two groups of telescopic grooves 21 rotate to the inside of the vibration groove 18, the impact head 22 is reset by the elastic potential energy of the compression spring 23, so that the impact head 22 hits the vibration plate 19. Further, the vibration plate 19 hits the material blocking partition 13, and the material blocking partition 13 will screen larger stones. The screened stones fall into the inside of the receiving plate 24 through the vibration and tilt of the material blocking partition 13, and finally fall into the inside of the receiving plate 24 through the guide plate 26 inside the receiving plate 24 to realize automatic cleaning, so as to prevent the material blocking partition 13 from being blocked and the stones from solidifying.

[0053] Before the transportation operation is required, the staff first aligns the second connecting block 30 on the outer wall of the connecting tube 10 and the first connecting block 28 on the outer wall of the discharge pipe 9, and then inserts the second connecting block 30 into the first connecting block 28. When the second connecting block 30 is inserted, the inclined surface of the mounting block 32 will abut against the first connecting block 28, so that the mounting block 32 is received in the movable groove 31, and the spring 33 is compressed at this time. Then the staff rotates the connecting tube 10, and when the movable groove 31 and the control groove 29 are aligned with each other, the mounting block 32 will pop up through the elastic potential energy of the spring 33, so that the mounting block 32 enters the control groove 29 to complete the fixation.
