Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically a bucket wheel excavator and construction equipment suitable for deep foundation pits. Background Technology

[0002] The main construction feature of foundation pit operations is simultaneous excavation and support. Deep foundation pit excavation requires layered support. The depth of excavation at one time is strictly limited according to the terrain conditions to prevent accidents such as collapse.

[0003] The current deep foundation pit excavation mainly adopts the following process: starting from the excavation surface of the deep foundation pit, the excavator on the excavation surface transfers the soil to the next level of the soil transfer platform. Then, the excavator on the parking platform above the soil transfer platform transfers the soil from the soil transfer platform to the next level of the soil transfer platform. Then, the excavator on the next level of the soil transfer platform transfers the soil from the soil transfer platform to the next level of the soil transfer platform, and so on, until the excavator on the top of the deep foundation pit transfers the soil from the top soil transfer platform to the dump truck on the top of the deep foundation pit. Finally, the dump truck transports the soil to the designated unloading point.

[0004] While the above method is simple and easy to implement, it is inefficient, requires multiple excavators to work simultaneously, and can only dig backwards, not continuously. In addition, with multiple people working at the same time, in addition to excavator operators, on-site dispatchers and safety managers are also needed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1 This utility model provides a technical solution: a bucket wheel excavator suitable for deep foundation pits, including a tracked walking mechanism 2, a bucket wheel boom slewing mechanism 11 on the tracked walking mechanism 2, an L-shaped gantry 1 on the bucket wheel boom slewing mechanism 11, a bucket wheel boom 3 on the L-shaped gantry 1, and a material conveyor integrated on the bucket wheel boom 3; a bucket wheel 31 is rotatably arranged at the front end of the bucket wheel boom 3, and the rear end of the bucket wheel boom 3 is movably mounted on the L-shaped gantry 1, and the tilt angle of the bucket wheel boom 3 is adjusted by a bucket wheel boom luffing mechanism 32 mounted on the L-shaped gantry 1.

[0022] A material unloading conveyor slewing mechanism 5 is installed on the L-shaped gantry 1. A material unloading conveyor 51 is installed on the material unloading conveyor slewing mechanism 5. The material unloading conveyor slewing mechanism 5 is used to control the horizontal swing of the material unloading conveyor 51 (i.e., swinging and resetting in the horizontal direction). A material unloading conveyor luffing mechanism 52 is installed on the material unloading conveyor slewing mechanism 5. The material unloading conveyor luffing mechanism 52 is used to adjust the tilt angle of the material unloading conveyor 51. The feeding end of the material unloading conveyor 51 is connected to the lower part of the receiving hopper 4. The material unloading conveyor on the bucket wheel boom 3 is used to unload the material into the receiving hopper 4.

[0023] In this embodiment, the bucket wheel boom slewing mechanism 11 is used to control the horizontal swing of the L-shaped gantry 1, thereby driving the bucket wheel boom 3, unloading conveyor 51, etc. to swing horizontally. The track walking mechanism 2, the bucket wheel boom slewing mechanism 11, the bucket wheel boom luffing mechanism 32, the unloading conveyor slewing mechanism 5, and the unloading conveyor luffing mechanism 52 can all adopt existing technologies, and the operation of each part of the machine is controlled by setting up a hydraulic system, a power supply and distribution system, and a control system on the L-shaped gantry 1.

[0024] In this embodiment, when the bucket on the bucket wheel 31 contacts the material pile, the bucket begins to grab the material from the lower part of the bucket wheel 31 and gradually fills the bucket. After the bucket is filled with material, as the bucket wheel 31 rotates to the top of the bucket wheel 31, the material is unloaded onto the material conveyor integrated into the bucket wheel boom 3 by its own weight, and then transferred from the rear end of the material conveyor to the receiving hopper 4. Since the lower part of the receiving hopper 4 is connected to the feed end of the unloading conveyor 51, the material can be transferred to an external conveying mechanism such as a belt conveyor through the unloading conveyor 51, so that the material can be finally unloaded to the designated unloading site.

[0025] In order to ensure continuous material extraction, in addition to the rotatable bucket wheel 31, a bucket wheel boom slewing mechanism 11 and a discharge conveyor slewing mechanism 5 are set up to control the horizontal swing of the bucket wheel boom 3 and the discharge conveyor 51 respectively; a bucket wheel boom luffing mechanism 32 and a discharge conveyor luffing mechanism 52 are set up to control the angle of the bucket wheel boom 3 and the discharge conveyor 51 respectively; and the crawler walking mechanism 2 enables the forward and backward movement of the whole machine to adjust the height and width of material extraction and unloading, etc.

[0026] Example 2

[0027] Please see again Figure 1 Based on Embodiment 1, this embodiment adopts a telescopic conveyor to increase site adaptability. During operation, the discharge port moves forward and backward with the forward and backward movement of the whole machine, or the position of the discharge port is controlled by the telescopic movement of the discharge conveyor 51.

[0028] A telescopic pusher 21 is installed on the tracked walking mechanism 2. When there is soil or other material in front of the tracked walking mechanism 2, the material can be pushed to the bottom of the bucket wheel 31. The tracked walking mechanism 2 includes a high-torque walking motor, which can save itself even if it gets stuck in the mud.

[0029] Example 3

[0030] Please see Figure 1 and Figure 2 This embodiment discloses a construction operation equipment, including a support 9, a hoist 8, and a bucket wheel excavator for deep foundation pits as described in Embodiment 2. The bucket wheel excavator can transport materials to the hopper of the hoist 8 via a transfer conveyor 10 located in the foundation pit 7. Specifically, the transfer conveyor 10 is located below the discharge port of the unloading conveyor 51. The support 9 is arranged around the foundation pit 7 for protection of the foundation pit 7. The hoist 8 is used to lift materials to the top of the foundation pit 7 and transfer the materials to a designated unloading position via at least one transfer conveyor 10 or a transport vehicle.

[0031] In this embodiment, the transfer conveyor 10 below the discharge port of the unloading conveyor 51 is also movable, and its movement direction is consistent with the movement of the bucket wheel excavator. After receiving the material, the transfer conveyor 10 below the discharge port of the unloading conveyor 51 directly conveys it to the hopper of the elevator 8. The elevator 8 then lifts the material and transfers it to a designated location via the transfer conveyor 10 or other equipment such as a transport vehicle set on the platform 6. The transfer conveyor 10 below the discharge port of the unloading conveyor 51 does not need to move within the telescopic length range of the unloading conveyor 51, which provides conditions for continuous operation for a period of time, enabling one operator to complete the entire task. By reducing human intervention, both work efficiency and work safety are improved.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
