Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and in particular to a backhoe pressing and sending anti-fracture device for wood piles and a pressing and sending method thereof. BACKGROUND

[0002] As a low-cost and simple-to-operate temporary support method, wood piles are widely used for temporary support and temporary rescue of landslide excavation. In order to be convenient to operate and reasonable in cost, a backhoe pressing method is often used to drive wood piles, such as the backhoe 8 shown in the accompanying drawings. Figure 4 The bucket 9 of the backhoe 8 is in hard contact with the pile head of the wood pile 7 to be pressed and sent. When driving, the bucket is pressed downward. During the pressing process, the bucket of the backhoe directly presses the pile head, which may cause damage to the pile head. In addition, due to the limitation of the mechanical arm of the backhoe 8, the bucket 9 is difficult to achieve complete vertical pressing and sending, but will have a certain front and back swing (as shown by the arc-shaped arrow in the figure). The horizontal force of the front and back swing of the bucket will cause the wood pile 7 to be pressed and sent to shake synchronously. Improper operation may even cause inclined piles and broken piles. SUMMARY

[0003] The present application aims to overcome the defects of the prior art and provide a backhoe pressing and sending anti-fracture device for wood piles and a pressing and sending method thereof. The device avoids direct contact between the bucket and the pile head. When the bucket swings forward and backward, the horizontal force of the bucket is converted into the rotating force of the roller, eliminating the horizontal force on the pile head, so that the pile head is only subjected to vertical pressure, thereby achieving the protection of the wood pile.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present application is a backhoe pressing and sending anti-fracture device for wood piles, comprising:

[0005] a sleeve for being sleeved on the top of the wood pile to be pressed and sent, the inner diameter of the sleeve being greater than the diameter of the wood pile to be pressed and sent;

[0006] a connecting piece for detachably connecting the sleeve with the wood pile to be pressed and sent;

[0007] a roller for pressing and sending by the backhoe, the roller being located above the wood pile to be pressed and sent and being rotatably connected to the top of the sleeve.

[0008] The backhoe pressing and sending anti-fracture device for wood piles is further improved in that the top of the sleeve is rotatably connected with a turntable in the horizontal direction, the turntable is located above the wood pile to be pressed and sent, and the roller is connected to the top of the turntable.

[0009] The backhoe pressing and sending anti-fracture device for wood piles is further improved in that the top of the turntable is connected with two ear plates at intervals, a rotating shaft is connected between the two ear plates, and the roller is rotatably sleeved on the rotating shaft.

[0010] The excavator pressing and sending anti-fracture device for wood piles further improves that the connecting piece comprises a plurality of lead screws, and a plurality of threaded holes for the plurality of lead screws to screw through and abut against the wood pile to be pressed and sent are arranged at intervals on the outer periphery of the sleeve.

[0011] The excavator pressing and sending anti-fracture device for wood piles further improves that each lead screw is rotationally connected with an arc-shaped clamping plate close to one end of the wood pile to be pressed and sent, and the arc-shaped clamping plate is matched with the wood pile to be pressed and sent.

[0012] An excavator pressing and sending method for wood piles comprises the following steps:

[0013] Step 1: providing the excavator pressing and sending anti-fracture device for wood piles, and connecting the sleeve to the top of the wood pile to be pressed and sent by the connecting piece;

[0014] Step 2: providing an excavator, and controlling the excavator to move until the force direction of the bucket of the excavator is perpendicular to the rolling shaft of the roller;

[0015] Step 3: controlling the bucket to press and send the roller downward.

[0016] Compared with the prior art, the advantages of the present application are that:

[0017] 1. By arranging the roller, when the bucket swings forward and backward, the horizontal force of the bucket is converted into the rotating force of the roller, the horizontal force on the pile head is eliminated, the pile head is only subjected to vertical pressure, and the wood pile is protected.

[0018] 2. By arranging the connecting piece, the whole device is convenient to circulate, and the construction efficiency is improved. BRIEF DESCRIPTION OF DRAWINGS

[0027] The embodiments of the present application will be described in detail with specific examples, and other advantages and effects of the present application can be easily understood by those skilled in the art from the disclosure of the specification. The present application can also be implemented or applied by other different embodiments, and various modifications or changes can be made to the details in the specification without departing from the spirit of the present application.

[0028] The excavator pushing anti-breaking device for wood pile and the pushing method thereof of the present application will be described in further detail below in combination with the drawings and specific embodiments.

[0029] Please refer to Figures 1-6 The excavator pushing anti-breaking device for wood pile, comprising:

[0030] A sleeve 1 for being sleeved on the top of the wood pile 7 to be pushed, the inner diameter of the sleeve 1 being greater than the diameter of the wood pile 7 to be pushed;

[0031] A connecting piece for detachably connecting the sleeve 1 and the wood pile 7 to be pushed;

[0032] A roller 5 for pushing by the excavator 8, the roller 5 being located above the wood pile 7 to be pushed and being rotatably connected to the top of the sleeve 1.

[0033] As shown in Figure 5 and Figure 6 The clockwise rotating arrow is the force direction of the excavator bucket 9, the horizontal arrow is the horizontal force generated by the front and back swing of the excavator bucket 9, and the vertical arrow is the pressure of the excavator bucket 9 for pushing the wood pile 7 to be pushed; the counterclockwise rotating arrow is the rotating force of the roller 5. By setting the roller 5, when the excavator bucket 9 swings forward and backward, the horizontal force applied by the excavator bucket 9 will be converted into the rotating force of the roller 5 to eliminate the horizontal force, so that only the vertical pressure is applied to the pile head, thereby achieving the effect of protecting the wood pile 7 to be pushed.

[0034] Preferably, the top of the sleeve 1 is rotationally connected with a rotating disc 2 in horizontal direction, the rotating disc is located above the wood pile to be pressed, and the roller 5 is connected to the top of the rotating disc 2.

[0035] Specifically, the bottom of the rotating disc 2 extends downward and forms an extension section, the extension section is inserted into the sleeve 1, and a rotating bearing is connected between the extension section and the inner wall of the sleeve 1.

[0036] By arranging the rotating disc 2, the rotating disc 2 can be rotated before the excavator 8 presses, so as to match the pose of the bucket 9, and the force direction of the excavator 8 is perpendicular to the roller shaft of the roller 5, thereby improving the practicability.

[0037] Preferably, the top of the rotating disc 2 is spaced apart and connected with two ear plates 3, the two ear plates 3 are connected with a rotating shaft 4, and the roller 5 is rotationally sleeved on the rotating shaft 4.
