Description

Technical Field

[0001] This application relates to the field of construction machinery technology, and in particular to an automatic concrete conveying and placing device for vertical shafts. Background Technology

[0002] Traditionally, vertical shaft concrete construction relies on manual or semi-mechanized material placement, resulting in low efficiency and poor safety. In recent years, inclined chute conveying and pumping technologies have been gradually applied, but risks of segregation and pipe blockage remain due to limitations in shaft depth and concrete properties. The industry commonly employs segmented pouring or bucket transfer methods, leading to construction cycles extending by more than 30%.

[0003] In existing vertical shaft concrete construction, the level of automation needs to be improved, and fully automatic continuous material placement cannot be achieved, requiring many manual intervention steps; the quality of concrete is difficult to control during transportation, and segregation is prone to occur. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an automatic concrete conveying and placing device for vertical shafts, which overcomes the deficiencies of existing technologies. It aims to solve the problems in existing vertical shaft concrete construction where the degree of automation needs to be improved, and fully automatic continuous placing cannot be achieved, requiring a large number of manual intervention steps; the quality of concrete is difficult to control during the conveying process, and segregation is prone to occur.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic concrete conveying and placing device for a vertical shaft, comprising a foundation, a vertical shaft being formed inside the foundation, a suspension frame and a conveying system being provided above the foundation, the conveying system comprising a support frame, multiple sets of drive wheels being provided at the bottom of the support frame, a concrete mixer being provided above the support frame, a rotary distributor being provided at the bottom of the suspension frame near the vertical shaft, an inclined chute being provided between the rotary distributor and the concrete mixer, multiple sets of vibrators being provided outside the inclined chute, multiple sets of vertical shaft support frames being provided inside the vertical shaft, a chute pipe being provided at the bottom of the rotary distributor, a cross-shaped fixing frame being provided inside the vertical shaft support frame located at the bottom of the vertical shaft, a material unloading robot arm being provided at the bottom of the cross-shaped fixing frame, the bottom of the chute pipe being connected to the interior of the material unloading robot arm, and a buffer chamber being provided inside the chute pipe.

[0006] By adopting the above technical solution and setting up a foundation, during use, the concrete pumped from the concrete mixer will enter the rotary distributor through an inclined chute for diversion. Multiple sets of vibrators installed outside the inclined chute will vibrate the concrete to prevent material blockage. Subsequently, the concrete will flow directly into the unloading robotic arm through the bottom chute. Then, the angle of the unloading robotic arm will be changed according to the material placement needs to achieve rapid material placement at the bottom of the shaft. At the same time, multiple sets of shaft support frames installed outside can protect the side walls of the shaft and effectively fix the unloading robotic arm and the chute. In this way, the material placement in the shaft can be completed automatically, improving the efficiency of material placement and construction time, reducing the number of personnel working underground, and effectively improving safety.

[0007] As a preferred technical solution of this application, the number of buffer chambers is set to multiple groups, and each group of buffer chambers is fixedly connected to the shaft support frame. The multiple groups of buffer chambers are arranged in series inside the ash chute.

[0008] By adopting the above technical solution and setting multiple buffer chambers, multi-level buffering can be provided for the concrete falling from the rotary diverter during use, reducing the direct impact of the concrete on the inner wall of the ash chute at the bottom of the shaft when falling, effectively improving service life and enhancing safety.

[0009] As a preferred technical solution of this application, a top plate is provided above the inclined chute, an installation groove is provided inside the top plate, an anti-segregation grid is provided inside the installation groove, and the bottom of the anti-segregation grid is located inside the inclined chute.

[0010] By adopting the above technical solution and setting a top plate, the upper part of the inclined chute can be protected during use. The anti-segregation grid can effectively reduce the segregation rate of concrete and improve the stability of subsequent material placement.

[0011] As a preferred technical solution of this application, the cross-shaped fixing frame is provided with multiple sets of infrared sensor groups on its exterior, and the multiple sets of infrared sensor groups are electrically connected to the unloading robotic arm.

[0012] By adopting the above technical solution and setting up an infrared sensor group, the material placement at the bottom of the shaft can be better detected during use. This, combined with the material unloading robotic arm, further improves the material placement effect and enhances the practicality of the device.

[0013] As a preferred technical solution of this application, each of the bottom output ends of the multiple sets of buffer chambers is provided with a flow regulating valve, and the multiple sets of flow regulating valves are electrically connected to the rotary distributor.

[0014] By adopting the above technical solution and setting a flow regulating valve, the flow rate of the ash chute can be adjusted during use, making it more convenient and stable and improving the practicality of the device.

[0015] As a preferred technical solution of this application, a control panel is provided on one side of the suspension frame, and the control panel is electrically connected to the unloading robotic arm, the conveying system and the rotary distributor.

[0016] By adopting the above technical solution and setting up a control panel, the equipment can be easily adjusted by staff above the foundation during use, thus improving its practicality.

[0017] As a preferred technical solution of this application, multiple sets of suspension rods are provided on the top of the shaft support frame located at the uppermost part of the shaft, and the tops of the multiple sets of suspension rods are fixedly connected to the suspension frame.

[0018] By adopting the above technical solutions and setting suspension rods, the internal stability of the shaft support frame can be improved, the support effect can be enhanced, and the safety can be improved.

[0019] The beneficial effects of this application are: 1. By setting up a foundation, during operation, the concrete pumped from the concrete mixer flows through an inclined chute into the rotary distributor for diversion. Multiple vibrators installed outside the inclined chute vibrate the concrete to prevent blockage. Subsequently, the concrete flows directly into the unloading robotic arm along the bottom chute. The angle of the unloading robotic arm is adjusted according to the material placement needs, achieving rapid material placement at the bottom of the shaft. Simultaneously, multiple external shaft support frames protect the shaft's sidewalls and effectively secure the unloading robotic arm and chute. This automated material placement within the shaft improves efficiency and construction time, reduces the number of personnel working underground, and effectively enhances safety.

[0020] 2. By setting multiple buffer chambers, multi-stage buffering can be provided for the concrete falling from the rotary diverter during use, reducing the direct impact of the concrete on the inner wall of the ash chute at the bottom of the shaft during falling, effectively improving service life and enhancing safety.
