Description

Technical Field

[0001] This application relates to the field of pile foundation construction technology, and in particular to a structure combining the soil outlet and chute of a walking pile driver. Background Technology

[0002] Walking pile drivers are commonly used construction equipment in building foundation engineering. They move via a walking mechanism and are suitable for pile foundation construction under various geological conditions. During the upward movement of the rotating drill head, the excavated soil produced during drilling falls into a soil collection device and is discharged from its outlet.

[0003] Currently, the conventional method is to guide the discharged construction waste to a designated location by constructing chutes, but this method has the following drawbacks: 1) The overlapping connection method is not stable. When the pile driver is vibrating, the chute is prone to loosening and falling off, which affects the construction efficiency. 2) During the excavation process, the excavated soil is prone to fall from both sides of the chute, causing environmental pollution at the construction site and increasing the amount of cleaning work; 3) The chute angle is fixed and cannot be flexibly adjusted according to the actual conditions of the construction site, resulting in poor adaptability. Utility Model Content

[0004] Therefore, it is necessary to provide a structure that combines the soil outlet and chute of a walking pile driver to overcome the defects mentioned in the background art.

[0005] A chute structure for the soil outlet of a walking pile driver includes an electric hoist, a chute channel, and a collection device. The electric hoist is located on both sides of one end of the chute channel. Multiple pairs of lifting lugs are arranged on both sides of the soil outlet of the collection device, and the multiple pairs of lifting lugs are connected to the electric hoist via connecting ropes. The chute channel includes a connecting cylinder and a guide cylinder. The connecting cylinder is fixed to the soil outlet of the collection device, and the connecting cylinder and the guide cylinder are connected by a ball joint assembly. An adjustable guide device is detachably connected to the end of the guide cylinder.

[0006] As a preferred embodiment of the chute structure for the soil outlet of the walking pile driver in this utility model, the ball joint assembly includes a ball cup fixedly connected to the connecting cylinder and a ball head fixedly connected to the guide cylinder, and the inner and outer sides of the ball joint assembly are covered with wear-resistant sealing sleeves.

[0007] As a preferred embodiment of the chute structure at the soil outlet of the walking pile driver in this utility model, the top of the guide tube is provided with an outward-folding dredging window.

[0008] As a preferred embodiment of the chute structure at the soil outlet of the walking pile driver in this utility model, the adjustable guide device is L-shaped, with one end connected to the end of the guide tube via a connecting flange.

[0009] As a preferred embodiment of the chute structure for the soil outlet of the walking pile driver in this utility model, both the inner walls of the connecting cylinder and the guide cylinder are provided with replaceable wear-resistant liners.

[0010] The beneficial effects of this invention are: The connection between the collection device and the chute channel is more secure and will not easily fall off. The combination of multiple pairs of lifting lugs and ball joint swing enables the discharge port to be quickly and accurately positioned in a large space, which can effectively adapt to the dump trucks at different parking positions and greatly reduce the spillage of slag.

[0019] According to one aspect of this application, embodiments of this application provide a chute structure for the soil outlet of a walking pile driver, please refer to the accompanying document. Figure 1 and Figure 2 The walking pile driver's discharge chute structure includes an electric hoist 1000, a chute channel 2000, a collection device 3000, and lifting lugs 4000. The electric hoist 1000 is located on both sides of the chute channel 2000 away from the end of the collection device 3000. One end of the collection device 3000 is provided with a discharge port. Multiple pairs of lifting lugs 4000 are arranged on both sides of the discharge port of the collection device 3000. The multiple pairs of lifting lugs 4000 are connected to the electric hoist 1000 by connecting ropes. The chute channel 2000 includes a connecting cylinder 2100 and a guide cylinder 2200. The connecting cylinder 2100 is fixed to the discharge port of the collection device 3000. The connecting cylinder 2100 and the guide cylinder 2200 are connected by a ball joint assembly 2300. An adjustable guide device 2400 is detachably connected to the end of the guide cylinder 2200.

[0020] In one embodiment, the connecting cylinder 2100 is fixed to the soil outlet of the collecting device 3000 via a flange at one end. The guide cylinder 2200 is connected to the connecting cylinder 2100 via a ball joint assembly 2300. The ball joint assembly 2300 consists of a ball cup fixed to the connecting cylinder 2100 and a ball head fixed to the guide cylinder 2200, allowing the guide cylinder 2200 to swing in the pitch and horizontal directions within the ball cup. Several adjustable limit blocks can be added to the edge of the ball cup to mechanically limit the swing limit of the ball head and avoid interference with other parts of the equipment.

[0021] In one embodiment, multiple pairs of lifting lugs 4000 are arranged on both sides of the discharge port of the collecting device 3000. An electric hoist 1000 is fixed to the guide tube 2200. The hook at the end of the connecting rope of the electric hoist 1000 can be selectively connected to the lifting lugs 4000 that are located at the front, center, or rear, depending on actual needs. By connecting different lifting lugs 4000 and operating the electric hoist 1000 to raise and lower the wire rope, the inclination angle of the guide tube 2200 can be changed, thereby significantly changing the front-to-back position and height above the ground of the discharge port.

[0022] In one embodiment, to ensure a seal, the entire ball joint assembly 2300 is covered by a wear-resistant sealing sleeve made of wear-resistant rubber on both the inner and outer sides to prevent soil from damaging the ball joint assembly 2300.

[0023] In one embodiment, the top of the flow guide 2200 is provided with an outward-folding drainage window, the cover of which is connected by a hinge and can be opened for quick treatment in case of blockage.

[0024] In one embodiment, the end of the guide tube 2200 is connected to an L-shaped adjustable guide device 2400 via a flange. By rotating the adjustable guide device 2400, the final landing point of the slag can be adjusted, and the falling slag can be finally constrained and guided.

[0025] In one embodiment, the inner walls of both the connecting cylinder 2100 and the guide cylinder 2200 are bolted with replaceable wear-resistant liners made of high-strength wear-resistant steel to cope with the severe abrasion of the slag.

[0026] Working principle: During construction, after the pile driver and collection device 3000 are installed and fixed, the operator selects a parking position for the muck truck according to the ground conditions. Based on the position of the muck truck's cargo box, the operator selects to hang the hook of the electric hoist 1000 on the appropriate lifting lug 4000 and operates the electric hoist 1000 to adjust the inclination angle of the guide tube 2200 so that the discharge port is accurately aligned with the truck box. After passing through the connecting tube 2100, the guide tube 2200 and the adjustable guiding device 2400, the muck is accurately guided into the muck truck.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
