Description

Technical Field

[0001] This utility model belongs to the field of concrete construction technology, and in particular relates to a dual-mode tracked mobile concrete placing boom. Background Technology

[0002] With the rapid development of the construction industry, the requirements for construction efficiency and quality are increasing. In concrete construction, the concrete placing boom is a key piece of equipment, and its performance directly affects construction efficiency and the quality of concrete pouring. While traditional concrete placing booms can complete basic concrete placing tasks, they have certain limitations in terms of mobility, adaptability, and ease of operation.

[0003] Currently, concrete placing booms on the market are mainly divided into two types: stationary and mobile. Stationary concrete placing booms have a simple structure and low cost, but they are inconvenient to move and difficult to adapt to changing construction sites. Mobile concrete placing booms, although they have a certain degree of mobility, mostly rely on wheeled chassis, which makes them less adaptable to complex terrains and lacks stability and load-bearing capacity.

[0004] Therefore, there is an urgent need for a dual-mode tracked mobile concrete placing boom to overcome the limitations of existing technologies, provide higher construction efficiency, stronger terrain adaptability and more convenient operation, thereby meeting the needs of the modern construction industry for high-performance concrete construction equipment. Utility Model Content

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with specific embodiments and the appendix, provides further details. Figure 1-4 The present invention will be described in further detail below. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.

[0020] Example 1 This utility model provides a dual-mode tracked mobile concrete placing boom, including a tracked chassis 7, a frame 6 mounted on the tracked chassis 7, and multiple retractable support leg components 8 symmetrically arranged on the frame 6. There are four support leg components, each mounted at one of the four corners of the frame 6. When the support leg components 8 are retracted, the tracks of the tracked chassis 7 are in contact with the ground for movement, enabling rapid travel and convenient mobility. When the support leg components 8 are extended, the tracks of the tracked chassis are separated from the ground. The placing boom enters a stable operating state, and the two modes can be switched freely to adapt to different working conditions. The extended support leg components effectively increase the support area of ​​the placing boom, lower the center of gravity, and make the placing boom more stable during operation, reducing swaying caused by uneven ground and other factors, thus improving placing accuracy and operational safety.

[0021] The support leg component 8 includes a telescopic base 81 connected to the frame 6. A leg is rotatably mounted on the telescopic base 81, and a drive groove 85 is provided on the leg. A telescopic cylinder 86 is disposed within the drive groove. One end of the telescopic cylinder 86 is rotatably connected to the telescopic base 81, and the connection end of the telescopic cylinder 86 to the telescopic base is higher than the connection end of the leg to the telescopic base 81. The other end of the telescopic cylinder 86 is rotatably connected to the leg. The retraction of the telescopic cylinder 86 causes the leg to rotate around the hinge point with the telescopic base 81, thus extending and retracting the leg. A support leg base 83 is rotatably mounted at the end of the leg. The rotatable mounting method of the support leg base 83 can automatically adjust the contact angle with the ground according to the ground conditions, making the contact between the leg and the ground more secure, further improving the stability of the support, and adapting to different terrain conditions.

[0022] The four corners of the frame 6 are rounded, and a rotating shaft 10 is located at the center of each corner. The telescopic base 81 is rotatably mounted on the frame 6 via the rotating shaft 10. The telescopic base 81 has a first limiting hole 9, and the frame 6 has multiple fixing holes corresponding to the first limiting hole. Preferably, there are two fixing holes: one for support and one for retraction. The first limiting hole 9 is fixed to one of the fixing holes by a limiting pin. The rotating shaft 10 and the first limiting hole 9 allow the support leg component 8 to be flexibly adjusted according to the actual working position and direction of the concrete placing machine when deployed, enabling the support leg to better adapt to different working environments and support requirements, thereby improving the applicability and flexibility of the concrete placing machine.

[0023] When the support legs need to be retracted, the limit pins are pulled out, pushing the support legs to rotate to the front and rear ends of the frame, significantly reducing the overall width of the placing boom during movement. On construction sites, especially in narrow passages, construction elevators, or on transport vehicles, the smaller width prevents collisions with other equipment or structures, improving the placing boom's maneuverability and facilitating flexible movement in complex environments. The retracted support legs, close to the frame, reduce the risk of accidental collisions with surrounding objects caused by the legs extending. This design is particularly important on construction sites due to their complex environment with various obstacles and personnel activity. By reducing the risk of collisions, the safety of the placing boom itself, as well as surrounding equipment and personnel, is effectively protected. Reducing the width of the placing boom also lowers transportation costs. During transportation, the smaller the space occupied by the placing boom, the higher the loading efficiency of the transport vehicle, thereby reducing transportation costs and improving the economic efficiency of the equipment.

[0024] The outrigger includes a first outrigger arm 82 and a second outrigger arm 84 connected at both ends. The angle between the first outrigger arm 82 and the second outrigger arm 84 toward the tracked base is greater than or equal to 90°. This allows the outrigger to better distribute the force when deployed, enhancing the load-bearing capacity of the support leg components, and also facilitates the storage of the outrigger, reducing the space occupied after storage.

[0025] The frame 6 is equipped with a slewing bearing base 3, and the placing arm component 1 is mounted on the slewing bearing base 3. The placing arm component 1 is equipped with a conveying pipe. It also includes a drive component 4, a counterweight 5, and a control component. The drive component includes an engine. The combination of the drive component, counterweight, and control component enables the various components of the placing machine to work collaboratively during operation. The drive component provides power for the movement of the placing arm, the counterweight plays a balancing role, preventing the placing arm from swaying due to a shift in the center of gravity during operation, and the control component achieves precise control of the entire placing machine, ensuring the smooth progress of the placing process.

[0026] The control components include a control system and a wireless remote control assembly. The wireless remote control assembly sends commands to the control system, which in turn transmits signals to the hydraulic valve assembly. The hydraulic valve assembly is a component that distributes hydraulic oil to drive the actuators. The hydraulic oil, after exiting the hydraulic pump, flows to the hydraulic valve assembly, which controls the flow of hydraulic oil to various boom cylinders, outrigger cylinders, or track travel motors. The hydraulic valve assembly drives the tracked chassis 7, slewing bearing base 3, boom assembly 1, and outrigger assembly 8. By sending commands to the control system, the wireless remote control assembly allows operators to remotely control the boom's movement, boom motion, and outrigger extension and retraction within a certain range, eliminating the need for direct contact with the equipment. This makes operation more convenient and safer, especially in complex construction environments, improving operational flexibility and efficiency. The control system transmits signals to the drive components, tracked chassis, slewing bearing base, boom assembly, conveying pipelines, and outrigger assembly, achieving centralized control and coordinated operation of each component. This improves the boom's intelligence level, reduces human error, and ensures the boom's operating efficiency and work quality.

[0027] The tracked chassis 7 includes track plates, track chains, drive wheels, idler wheels, tensioning devices, and support rollers. The track plates are connected by the track chains to form a track belt. The track chains surround the drive wheels and idler wheels. The drive wheels are located at the rear of the chassis to drive the track chains, and the idler wheels are located at the front to guide the track chains. The tensioning devices maintain the tension of the track chains, and the support rollers support the weight of the track plates. The track frame connects the various components and supports the entire structure.

[0028] Example 2 The difference between this embodiment and Embodiment 1 lies in the structure of the support leg component. The support leg component includes a support leg cylinder, the telescopic end of which is connected to the support leg base. The telescopic connection of the cylinder to the base allows for convenient adjustment of the support force of the support leg, enabling flexible adjustments based on the working load and ground conditions of the concrete placing boom, further improving the operational stability and adaptability of the boom.

[0029] When using the dual-mode tracked mobile concrete placing boom of this invention, operators can flexibly switch its working mode according to construction needs. When the placing boom needs to be moved, the operator only needs to pull up the limit pin and push the support leg components to rotate to the front and rear ends of the frame, so that the extension direction of the outriggers is consistent with the moving direction of the placing boom. This significantly reduces the width of the placing boom, making it easier for it to pass through narrow passages, construction elevators, or transport vehicles, reducing the risk of collisions with other equipment or structures, and lowering transportation costs. After reaching the construction position, the operator sends a command to the control system via the wireless remote control component. The control system transmits signals to each component, causing the support leg components to open, the tracks to separate from the ground, and the placing boom to enter a stable operating state. At this time, the outrigger base of the support leg components will automatically adjust the contact angle according to the ground conditions to ensure close contact with the ground, increase the support area, lower the center of gravity, and improve operational stability. In addition, the telescopic cylinders of the support leg components can flexibly adjust the support force according to the working load and ground conditions, further enhancing the adaptability and stability of the placing boom. Throughout the entire operation, operators do not need to directly contact the equipment. They can remotely control the movement of the concrete placing boom, the operation of the boom arm, and the extension and retraction of the support legs via a wireless remote control component. This makes operation convenient and safe, and significantly improves work efficiency, especially in complex construction environments. Simultaneously, the centralized control and coordinated operation of all components by the control system reduces human error, ensures the smooth progress of the concrete placing process, and enhances the intelligence level and operational quality of the concrete placing boom.
