Abstract
Description
Technical Field
[0001] This application relates to the field of concrete construction, and particularly to a concrete trailer pump. Background Art
[0002] With the rise of modern industry, the construction method with concrete as the main material has become one of the main structures in the construction industry, accounting for a large proportion in various engineering construction projects, making the development of concrete machinery last for a long time and showing an increasingly intense trend. The trailer concrete pump, abbreviated as trailer pump, is one of various concrete machinery, and is used for the transportation and pouring work in concrete construction.
[0003] The trailer pump includes a vehicle body with a bracket and wheels, and a hopper. A diesel pump or an electric pump is installed in the vehicle body as the main driving part. The hopper is for pouring concrete into. The pump continuously outputs the concrete in the hopper through an output pipeline to realize the pumping transportation of concrete. The vehicle frame can be telescopically supported. When the vehicle frame extends to support the ground and the wheels leave the ground, the trailer pump can be stably used. When the vehicle frame retracts, the existence of the wheels enables the trailer pump to be conveniently transferred. The output pipeline is installed below the hopper for concrete output.
[0004] For the existing trailer pump, since concrete needs to be continuously poured into the hopper, the height of the hopper cannot be too high, otherwise it is not convenient to pour concrete and the concrete is likely to spill out. The hopper cannot be too low either, otherwise the concrete capacity is insufficient. Utility Model Content
[0005] In order to facilitate the pouring of concrete and control the spilling of concrete on the basis of maintaining the height of the hopper, this application provides a concrete trailer pump.
[0006] The concrete trailer pump provided by this application adopts the following technical solutions:
[0007] A concrete trailer pump includes a vehicle body, a hopper and an auxiliary hopper. The hopper is installed at one end of the vehicle body. The auxiliary hopper is located on one side of the hopper along the length direction of the vehicle body. The upper part of the auxiliary hopper is rotatably connected to the hopper. Along the length direction of the vehicle body, the size of the auxiliary hopper is smaller than that of the hopper, and the auxiliary hopper is located at the center of the side of the hopper. An injection notch is formed on the side wall of the auxiliary hopper.
[0008] By adopting the above technical solutions, by setting the auxiliary hopper, since the injection notch of the auxiliary hopper is lower than the opening of the hopper, it is more convenient to pour concrete into the auxiliary hopper, and the concrete is not easily splashed to other places. Then, by flipping the auxiliary hopper, the concrete in the auxiliary hopper is further poured into the hopper. In this process, due to the cooperation between the auxiliary hopper and the hopper, the spilling of concrete is well controlled.
[0009] Optionally, a guiding plate is provided on one side of the auxiliary hopper close to the hopper. The auxiliary hopper is turned upwards and drives the guiding plate to extend into the hopper.
[0010] By adopting the above technical solution, the guiding plate is provided to better guide the concrete into the hopper.
[0011] Optionally, a guiding groove is formed on the side of the guiding plate facing away from the hopper, and the cross-section of the groove wall of the guiding groove is arc-shaped.
[0012] By adopting the above technical solution, the guiding groove formed on the guiding plate can better converge the concrete, making it not easy for the concrete to spill out.
[0013] Optionally, force-applying handles are provided on both sides of the auxiliary hopper. The two force-applying handles are located on the side of the hopper facing the auxiliary hopper, and the distances between the two force-applying handles and the hopper are the same. A U-shaped handle is provided on the side of the two force-applying handles away from the hopper, and the two ends of the U-shaped handle are correspondingly connected to the two force-applying handles.
[0014] By adopting the above technical solution, the force-applying handles are provided on the auxiliary hopper, making it more convenient to apply force to the auxiliary hopper to keep the auxiliary hopper in a state of pouring concrete, while the U-shaped handle can better apply force to lift the auxiliary hopper.
[0015] Optionally, a force-applying sleeve is rotatably installed in the middle of the U-shaped handle.
[0016] By adopting the above technical solution, the rotatable force-applying sleeve is provided, making it smoother to turn over the auxiliary hopper when pulling the auxiliary hopper with the U-shaped handle.
[0017] Optionally, a hydraulic support assembly is provided under the auxiliary hopper. The hydraulic support assembly includes a hydraulic base and a hydraulic cylinder. One end of the hydraulic cylinder is fixed to the hydraulic base, and the other end supports the auxiliary hopper.
[0018] By adopting the above technical solution, the setting of the hydraulic support assembly enables the auxiliary hopper to be supported by the hydraulic support assembly when injecting concrete, reducing the pressure at the connection between the auxiliary hopper and the hopper. When turning over the auxiliary hopper, the hydraulic support assembly is lowered so that the hydraulic support assembly no longer hinders the turning of the auxiliary hopper.
[0019] Optionally, a foot pedal button for controlling the opening and closing of the hydraulic cylinder is provided on the hydraulic base.
[0020] By adopting the above technical solution, the setting of the foot pedal button makes it more convenient to control the hydraulic support assembly.
[0021] Optionally, the injection notch is formed on the side of the auxiliary hopper away from the hopper.
[0022] By adopting the above technical solution, the injection gap is opened on the side of the auxiliary truck bucket away from the truck bucket, so that when the auxiliary truck bucket is turned over, concrete is not easy to flow out from the injection gap.
[0023] To sum up, by setting up the auxiliary truck bed, the injection notch of the auxiliary truck bed is lower than the opening of the truck bed, so it is more convenient to inject concrete into the auxiliary truck bed, and the concrete is not easy to splash to other places. Then, by turning over the auxiliary truck bed, the concrete in the auxiliary truck bed can be further poured into the truck bed. In this process, the auxiliary truck bed cooperates with the truck bed to well control the spillage of concrete. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figures 1-4 This application is described in further detail.
[0030] The embodiment of the present application discloses a trailer concrete pump.
[0031] Reference Figure 1 and Figure 2, a concrete placing boom, comprising a vehicle body 1, a hopper 2, an auxiliary hopper 3 and a hydraulic support assembly 4. Inside the vehicle body 1, a diesel pump or an electric pump is installed as the main driving element. A pair of wheels 5 are arranged at the middle position in the length direction of the vehicle body 1, so that the vehicle body 1 has a good moving function. Telescopic frames 6 are arranged at the four corners of the bottom of the vehicle body 1. The telescopic frames 6 are composed of two parts that are slidably matched up and down, and are equipped with locking structures, so that the height of the telescopic frames 6 can be adjusted, and then the height of the entire vehicle body 1 can be adjusted, so that the wheels 5 are lifted off the ground, and the entire placing boom is stably placed in place.
[0032] The hopper 2 is installed at one end of the vehicle body 1 for concrete injection, and then the concrete in the hopper 2 is pumped to the corresponding position through the driving element in the vehicle body 1. An output pipeline 24 is arranged on one side of the bottom of the hopper 2 away from the vehicle body 1 as the pipeline for concrete output.
[0033] Refer to Figure 1 and Figure 3 , the auxiliary hopper 3 is located on one side of the hopper 2 along the length direction of the vehicle body 1. The auxiliary hopper 3 is rotatably connected to the hopper 2. The auxiliary hopper 3 is used to directly receive concrete, and then the concrete is poured into the hopper 2 by flipping the auxiliary hopper 3. In this embodiment, there are two auxiliary hoppers 3, and the two auxiliary hoppers 3 are symmetrically arranged on both sides of the hopper 2. Specifically, the auxiliary hopper 3 is a shell with an upper opening. A hinge block 31 protrudes and overhangs from the side wall of the auxiliary hopper 3 close to the hopper 2. An upper part of the side wall of the hopper 2 facing the auxiliary hopper 3 protrudes and overhangs to form a connecting block 21. The connecting block 21 is provided with a hinge groove 22 for the hinge block 31 to be inserted and hinged. When the opening of the auxiliary hopper 3 faces upward and is in the non-flipped state, the side wall of the hinge block 31 facing the hopper 2 is a semi-cylindrical surface. At the same time, a travel block 23 also protrudes from the side wall of the hopper 2 facing the auxiliary hopper 3. The travel block 23 is located below the connecting block 21 and abuts against the side wall of the auxiliary hopper 3. The flipping travel of the hinge block 31 on the connecting block 21 is 90 degrees. When the opening of the auxiliary hopper 3 faces vertically upward, the hinge block 31 is supported by the connecting block 21, and the auxiliary hopper 3 is abutted by the travel block 23. When the opening of the auxiliary hopper 3 faces horizontally, the hinge block 31 is restricted from further flipping by the connecting block 21.
[0034] Meanwhile, the size of the attached hopper 3 along the length direction of the vehicle body 1 is smaller than that of the hopper 2, and the attached hopper 3 is located at the center of the side of the hopper 2. When the attached hopper 3 is flipped to pour cement, the opening of the attached hopper 3 is completely covered by the opening of the hopper 2. An injection notch 32 is provided at the upper part of the side wall of the attached hopper 3 facing away from the hopper 2, so that the height of the cement poured into the attached hopper 3 is lower than that of the hopper 2; a guiding plate 33 is also upwardly extended on the side of the attached hopper 3 close to the hopper 2, so that the attached hopper 3 is flipped upward and drives the guiding plate 33 to extend into the hopper 2. The guiding plate 33 is integrally connected with an inner wall of the attached hopper 3 and is inclined, so that when the attached hopper 3 is flipped to a horizontal opening, the cement flows better into the hopper 2 along the inclination of the guiding plate 33. At the same time, a guiding groove 34 is provided on the side of the guiding plate 33 facing away from the hopper 2, and the guiding groove 34 continues to extend along the inner wall of the attached hopper 3. At the same time, the cross section of the groove wall of the guiding groove 34 is arc-shaped, so that the cement is gathered in the middle of the guiding plate 33 and flows into the hopper 2.
[0035] Force-applying handles 7 are arranged on both sides of the attached hopper 3. The two force-applying handles 7 are located on the side of the side wall of the hopper 2 facing the attached hopper 3, and the distances between the two force-applying handles 7 and the hopper 2 are the same. A U-shaped handle 8 is arranged on the side of the two force-applying handles 7 away from the hopper 2. The two ends of the U-shaped handle 8 are correspondingly connected to the two force-applying handles 7 one by one, so that a space that can be held is also formed between the U-shaped handle 8 and the attached hopper 3. At the same time, the injection notch 32 is located above the U-shaped handle 8, and the part of the attached hopper 3 between the injection notch 32 and the U-shaped handle 8 protrudes outward to form an inclined inner wall and covers the upper part of the U-shaped handle 8, so that it is not easy to splash onto the U-shaped handle 8 when pouring concrete into the attached hopper 3.
[0036] A force-applying sleeve 9 is rotatably installed in the middle of the U-shaped handle 8. Specifically, the force-applying sleeve 9 can be directly sleeved in the middle of the U-shaped handle 8. At this time, the middle part of the U-shaped handle 8 is preferably a cylinder. The force-applying sleeve 9 can also itself be a cylinder and two coaxial cylinders with smaller diameters protrude from both ends and slide through the part of the U-shaped handle 8 after removing the middle part. At this time, the force-applying sleeve 9 is the middle part of the U-shaped handle 8.
[0037] Referring to Figure 3 and Figure 4 As shown in, a hydraulic support assembly 4 is arranged under the attached hopper 3. The hydraulic support assembly 4 includes a hydraulic base 41, a hydraulic cylinder 42 and a support plate 43. The hydraulic cylinder 42 is vertically arranged. The lower end of the hydraulic cylinder 42 is fixedly installed in the middle of the hydraulic base 41. The support plate 43 is installed on the piston rod of the hydraulic cylinder 42. A foot pedal button 44 for controlling the opening and closing of the hydraulic cylinder 42 is arranged on the hydraulic base 41. By stepping on the foot pedal button 44, the hydraulic cylinder 42 drives the support plate 43 to move downward, and no longer restricts the flipping of the attached hopper 3. When no longer stepping on the foot pedal button 44, the support plate 43 moves upward and supports and restricts the attached hopper 3.
[0038] The implementation principle of a concrete placing boom in an embodiment of this application is as follows: First, continuously pour concrete into the relatively short auxiliary hopper 3. Then, after the auxiliary hopper 3 is filled with concrete, step on the foot pedal button 44, raise the auxiliary hopper 3 through the U-shaped handle 8, and then transfer the grip to the force application handle 7 to better turn the auxiliary hopper 3 upwards to a state where concrete can be poured.
[0039] The above are all preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
