Description

Technical Field

[0001] The present invention relates to the field of engineering construction, and in particular to an intelligent concrete placing boom. Background Art

[0002] A concrete placing boom is the terminal equipment for pumping concrete. Its function is to deliver pumped concrete through pipes to the formwork of the component to be cast. The combined movement of its two-part rotating frame can cover all distribution points within the distribution radius. In conventional operation, the entire placing boom is moved by a crane or track. The bottom cantilever tube can be expanded as needed, or the crossbeam structure based on the support frame can be rotated according to the actual radius, allowing the placing boom to deliver concrete at multiple angles.

[0003] However, existing concrete placing booms usually have low conveying efficiency. When the pump pumps concrete into the pipeline, the pipelines passing through are respectively a fixed pipeline in the upper part and an expandable pipeline in the lower part. The pipeline has a long stroke. During the transportation process, due to the slow speed and the transportation based on the pressure inside the pipeline, heat will be exchanged with the external environment for a long time inside the pipeline. In the absence of stirring, the inner wall of the pipeline is prone to adhesion, which may cause blockage in severe cases, which will again affect the conveying efficiency inside the pipeline.

[0023] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example 1

[0025] like Figure 1-6As shown, the present invention provides an intelligent concrete placing boom, including a placing boom 1 and a pump. The placing boom 1 includes a crossbeam 101, a support frame 102 and a secondary rotation 103, wherein a feed pipe 104 is provided on the inner side of the support frame 102 and passes through the upper side of the crossbeam 101. A balance pipe 105 is provided on the top of the feed pipe 104. The balance pipe 105 is bent 180 degrees from the secondary rotation 103 to the lower side of the crossbeam 101 through multiple elbows, and the bottom of the secondary rotation 103 is a cantilever pipe 106. A support is provided between the balance pipe 105 and the crossbeam 101. An accelerating tube 2 is provided on the surface of the balancing tube 105. Connecting ends 201 are provided at the left and right ends of the accelerating tube 2. A cavity 202 is provided on the inner side. The cavity 202 is a hyperbolic Laval tube-shaped cavity. The inner wall of the channel 202 is provided with a rubber layer 203, and the outer surface of the rubber layer 203 is provided with a covering layer 204. The upper and lower surfaces of the covering layer 204 are provided with spring protrusions 205, and fixed arc plates 206 are provided on the left and right sides. Both ends of the covering layer 204 are fixedly connected to the inner wall of the accelerating tube 2. The surface of the spring protrusion 205 is provided with a support end 3, and the support end 3 is connected to the inner wall of the accelerating tube 2. The surface of the spring protrusion 205 at the minimum diameter of the covering layer 204 is provided with a fixing rod 4. The fixing rod 4 penetrates the surface of the accelerating tube 2 and is connected to the mounting plate 401. A heating module 402 is provided between the mounting plate 401 and the accelerating tube 2. The heating module 402 is used to heat the fixing rod 4. The number of the accelerating tubes 2 is not less than two.

[0026] The cross-section of the coating layer 204 is a circular structure. An insulation layer 5 is provided between the fixed arc plate 206 and the inner wall of the accelerating tube 2. The heating module 402 is fixedly connected to the accelerating tube 2, and the heating module 402 extends into the interior of the fixed rod 4. A resistive heating module is provided inside the fixed rod 4. The spring convex plate 205 is made of a steel leaf spring material.

[0027] A pressure sensor is provided at the center of the bottom end of the mounting plate 401, and a temperature sensor is provided at the bottom end of the fixing rod 4. The material distribution machine 1 also includes a main control unit, which includes a clock chip and an MCU microcontroller chip. The main control unit is electrically connected to the temperature sensor, pressure sensor, pump and heating module 402 respectively.

[0028] The inner wall of the rubber layer 203 is provided with a slideway 6 . The raised portion of the slideway 6 is a circular raised portion, and the slideway 6 is made of rubber material.

[0029] A straight rod 301 is provided at the top of the support end 3, and a mounting component 302 is provided at the bottom end of the straight rod 301. The straight rod 301 and the mounting component 302 are connected by a fixing bolt 303, wherein the mounting component 302 and the spring protrusion 205 are embedded and fastened, and the bottom end of the mounting component 302 is in contact with the spring protrusion.

[0030] The support ends 3 are symmetrically arranged on the surface of the spring protrusion 205. The support ends 3 are installed on the upper and lower spring protrusions 205. The number of the support ends 3 is not less than four pairs, and the slideway 6 is arranged in a spiral inclined shape.

[0031] The overall structure is based on the conventional concrete placing boom 1 structure. The feed pipe 104 extends upward from the support frame 102 to the upper side of the beam 101. The beam 101 is controlled to rotate left and right by the rotation mechanism at the support frame 102. The cantilever pipe 106 located at the lower layer can be unfolded based on the power structure control on the beam 101 to increase the overall casting range.

[0032] Specifically, the balance pipe 105 at the top is set in a horizontal state for a long time, and the balance pipe 105 is located at the highest point of the entire pipeline. Therefore, in the concrete transportation process, the transportation rate of the balance pipe 105 is usually low, and the balance pipe 105 located in the middle is easy to exchange heat with the external environment, resulting in the lack of mixing in the transportation process. The concrete is easily blocked on the inside. Therefore, the balance pipe 105 is placed at the top. Figure 1 A detachable accelerating tube 2 is installed at the structure. The accelerating tube 2 is installed on the balancing tube 105 based on the connecting ends 201 at both ends. The outer tube material is the same as that of the balancing tube 105, and the inner layer is provided with a coating layer 204 in the style of a Laval tube. The cavity 202 formed is welded to the inner wall of the accelerating tube 2 in an integral manner. When concrete pumped into the balancing tube 105 at a high pressure flows through the coating layer 204 area, the fluid structure can be accelerated under high pressure. That is, the cross-sectional area is reduced at the front and restored at the rear, thereby increasing the passage time. Because the concrete is in a semi-gel-like fluid structure in a relatively hot state, negative pressure is generated at the front end during the acceleration process, and the pressure in the pipe is increased at the rear end. In the case of multi-end accelerating tubes 2, the flow rate at the balancing tube 105 can be further increased, thereby increasing the transportation efficiency at the balancing tube 105.

[0033] Furthermore, the covering layer 204 is provided with spring protrusions 205 on the upper and lower sides, and fixed fixed arc plates 206 on both sides, and a support end 3 is provided in the area of ​​the spring protrusion 205 to enhance the degree of fixation in the area, and a fixing rod 4 structure for strengthening the narrow tube is also provided at the accelerating tube 2, and the spring protrusion 205 and the fixing arc plate 206 are welded into a whole; and when the inside of the balancing tube 105 is blocked or the pressure inside the balancing tube 105 is too high, the first thing to be deformed is the narrower spring protrusion 205, which will push up the fixing rod 4 structure when expanding outward, thereby increasing the pressure on the mounting plate 401, and a pressure sensor is provided in the hollow part of the middle of the mounting plate 401. The mounting plate 401 is directly fixed to the heating module 402 mainly by bolts or threaded structures at the edge. Therefore, when it is under pressure, data will be transmitted back to the main control unit, and the main control unit can control the pump to reduce the pumping pressure according to the actual pressure increase. If necessary, a pressure threshold can also be set to avoid phenomena such as internal pipe burst.

[0034] The heating module 402 is directly fixed to the outer surface of the accelerating tube 2. The heating module 402 is directly connected to the wires from the side of the fixed rod 4. A resistive heating structure is provided inside the fixed rod 4. When the heat exchange efficiency is too high due to the excessively fast delivery rate of the balancing tube 105 and the delivery rate of the inner balancing tube 105 is too low, a slower rate is formed inside the tube, thereby increasing the heat exchange time with the tube wall of the balancing tube 105, the temperature sensors on both sides of the lowest end of the fixed rod 4 will detect the flow temperature on the coating layer 204 and transmit the data to the main control unit. The main control unit controls the heating module 402 to heat the tube wall surface based on the fixed rod 4, thereby increasing the temperature of the concrete in the pipeline, for example in winter or cold weather. At the same time, it can also form a temperature detection effect for different pipeline areas based on the nodes of multiple accelerating tubes 2 on the balancing tube 105, thereby preventing the formation of gel-like concrete in the tube due to excessively low temperature, which may cause blockage.

[0035] In order to reduce the blockage in the pipe and the adhesion to the pipe wall, a slide 6-shaped structure is provided at the rubber layer 203 on the surface of the coating layer 204. Figure 5 As shown, the colloidal structure can be prevented from directly adhering to the smooth surface. If the slideway 6 is further configured in a spiral rifling structure, the semi-colloidal structure or the larger particles of the colloidal structure located on the outer layer can be rotated in the tube. The rotational advancement can reduce the turbulence of the concrete in the tube caused by corrosion or unevenness of the tube wall. When the balancing tube 105 is severely blocked, the accelerating tube 2 can be disassembled through the connecting end 201 to expose the blocked area in the tube for easy handling.

[0036] Its structure is simple, easy to install and disassemble as well as subsequent maintenance. The accelerating tube 2 set can greatly increase the transportation efficiency of concrete, and can shorten the time by 10% compared with the previous transportation method. The front and rear ends of the installed coating 204 are connected to the accelerating tube 2. Straight rods 301, mounting components 302 and fixing bolts 303 are provided at the upper and lower support ends 3. The mounting component 302 pushes down the coating 204 and the spring protrusion 205 to achieve a limiting effect on the overall structure on the inside and enhance the stability of the inside.

[0037] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
