Description

Technical Field

[0001] This application relates to the field of boom technology, specifically a boom for a pumping system. Background Technology

[0002] The boom of the pumping system is a foldable concrete conveying equipment used in concrete mixing and pumping trucks. This equipment can accurately transport the mixed concrete from the truck body to the pouring location at a distance, at a high altitude or in a complex working condition, such as the floors of high-rise buildings, bridge piers, etc. It consists of multiple foldable and hinged metal booms, with integrated concrete conveying pipes inside and a liquid outlet pipe at the end. However, traditional boom assemblies have significant shortcomings in practical use: when the boom's outlet pipe is close to the construction site to deliver concrete, the weight of the concrete will cause the outlet pipe to shake violently, affecting the accuracy of concrete placement; at the same time, the outlet pipe needs to be frequently changed according to construction needs, and traditional outlet pipes lack a stable support and grip structure. For workers, holding and operating the pipe for a long time is not only labor-intensive, but also prone to concrete spillage due to unstable grip, affecting construction efficiency and quality.

[0003] Therefore, it is necessary to provide a boom for a pumping system to solve the above problems. Utility Model Content

[0004] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a boom for a pumping system that can stably pick up the liquid outlet pipe, thereby solving the problem that the liquid outlet pipe is prone to large-scale shaking and unstable gripping during use.

[0005] The technical solution adopted by this application to solve its technical problem is: a boom for a pumping system, including a boom assembly, the boom assembly including a support seat fixedly installed on a pump truck, a plurality of rods hinged on the support seat, the rods being able to fold and extend by being driven by the hydraulic module of the pump truck, a conveying pipe for conveying materials being fixedly installed on the rods, a liquid outlet pipe being fixedly installed at the end of the conveying pipe, and a support module for improving the handheld stability and operating comfort of the liquid outlet pipe being provided on the liquid outlet pipe.

[0006] Furthermore, the support module includes a collar slidably mounted on the outside of the liquid outlet pipe, a handle fixedly mounted on the collar, the surface of the handle having an anti-slip texture, and the handle being able to slide up and down along the liquid outlet pipe with the collar to adjust its height position.

[0007] Furthermore, several sets of fixing blocks are fixedly installed on the collar, and a fixing plate a is fixedly installed on the liquid outlet pipe. An elastic element is provided between the fixing plate a and the fixing blocks.

[0008] Furthermore, a fixing plate b is fixedly installed on the liquid outlet tube. The fixing plate b is located at the bottom of the handle, and the range of motion of the handle is limited between the fixing plate a and the fixing plate b.

[0009] Furthermore, a support rod is provided inside the elastic element. The support rod passes through the fixing block, and its upper and lower ends are respectively fixedly connected to the bottom of the fixing piece a and the top of the fixing piece b.

[0010] Furthermore, a threaded post is fixedly installed on the fixing block, and a rotating ring is threadedly connected to the threaded post. The rotating ring is fixedly connected to the bottom of the elastic element, and the tightness of the elastic element can be adjusted by rotating the rotating ring.

[0011] Furthermore, the support base is made of high-strength cast steel and has an integrated hydraulic rotary drive device, which can achieve 360-degree angle adjustment. The rod body is a multi-section telescopic boom.

[0012] The beneficial effects of this application are: This application provides a boom for a pumping system. By setting a support module at the outlet pipe and using the handle on the module for easy handling by workers, the stability of the outlet pipe is improved, preventing it from shaking excessively due to the weight of the concrete. At the same time, it reduces the labor intensity of workers and improves the operating efficiency and material placement accuracy of the pumping system. Attached Figure Description

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0016] like Figures 1-4 As shown, this application provides a boom for a pumping system. The boom includes a boom assembly 10, on which a support module is provided. The boom assembly 10 is used to realize long-distance, multi-angle conveying of concrete, while the support module is used to improve the handheld stability and operating comfort of the discharge pipe 14.

[0017] The boom assembly 10 includes a support base 11 that is bolted to the pump truck. The support base 11 integrates a hydraulic rotary drive device, which can support the boom assembly 10 as a whole in 360 degrees and adjust the angle to adapt to the material placement requirements of different construction directions.

[0018] Meanwhile, several sets of rods 12 are hydraulically hinged to the support base 11. The rods 12 are multi-section telescopic booms. The rods 12 can be driven by the hydraulic module on the pump truck, and the several sets of rods 12 can be freely extended, so that the rods 12 can flexibly approach the location where construction is needed.

[0019] Furthermore, a conveying pipe 13 for conveying concrete is fixedly installed on the rod 12. The conveying pipe 13 can be synchronously adjusted through the hinge direction of the rod 12. At the same time, a liquid outlet pipe 14 is fixedly installed at the end of the conveying pipe 13, which can flexibly convey and discharge concrete.

[0020] In use: drive the pump truck to the vicinity of the construction site, then start the hydraulic module to drive the rod 12 to extend, adjust the outlet pipe 14 to the pouring position, and then start the pumping system. The concrete is transported to the designated area through the delivery pipe 13 and the outlet pipe 14. During this period, the staff holds the outlet pipe 14 stably through the support module to achieve precise material placement.

[0021] The liquid outlet tube 14 is equipped with a support module for easy and stable handling. The support module includes a collar 141 that is slidably mounted on the outside of the liquid outlet tube 14 via a linear bearing. A handle 142 that conforms to ergonomics is fixedly mounted on the collar 141. The handle 142 makes it easy for the operator to pick up the liquid outlet tube. As the collar 141 slides up and down on the outside of the liquid outlet tube 14, the handle 142 can be positioned at different heights of the liquid outlet tube 14 to accommodate operators of different heights and operating habits. This solves the instability problem caused by the traditional method of picking up the liquid outlet tube 14 by simply holding its surface with the hand.

[0022] Several sets of fixing blocks 144 are fixedly installed on the collar 141, and a fixing plate a143 is fixedly installed on the liquid outlet pipe 14. At the same time, an elastic element 145 is provided between the fixing plate a143 and the several sets of fixing blocks 144. Through the buffering effect of the elastic element 145, the handle 142 has a certain elasticity, thereby improving the comfort of operation.

[0023] Furthermore, a fixing plate b147 is fixedly installed on the liquid outlet pipe 14 by welding. The fixing plate b147 is located at the bottom of the handle 142. At the same time, the handle 142 can only be operated between the fixing plate a143 and the fixing plate b147. When the handle 142 is pushed down, the fixing plate b147 can limit the movement distance of the handle 142 to avoid excessive operation that could cause the liquid outlet pipe 14 to deviate.

[0024] Meanwhile, a support rod 146 is provided inside the elastic element 145. The support rod 146 can pass through the fixing block 144. The upper and lower parts of the support rod 146 are fixedly connected to the bottom of the fixing piece a143 and the top of the fixing piece b147, respectively. The support rod 146 can provide rigid support for the elastic element 145, prevent the elastic element 145 from bending excessively when it expands and contracts, and improve stability.

[0025] Finally, a threaded post 148 is fixedly installed on the fixed block 144 by welding. The bottom of the elastic element 145 is located outside the threaded post 148. At the same time, a swivel 149 is threadedly connected to the threaded post 148, and the swivel 149 is fixedly connected to the bottom of the elastic element 145. By rotating the rotating ring 149, its position on the threaded column 148 can be adjusted vertically: when the rotating ring 149 moves upward, the length of the elastic element 145 decreases and the elastic tension increases; when the rotating ring 149 moves downward, the length of the elastic element 145 increases and the elastic tension decreases. This allows for adjustments based on the operator's habits and the concrete conveying pressure.

[0026] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
