[0003] Because mining facilities usually require a solid foundation to support heavy equipment and structures, pile drivers can be used to build various foundations, such as pile foundations and pile columns, to ensure the stability and safety of the facilities.

[0004] In the process of realizing the utility model, the inventor discovered that the prior art had the following problems: 1. When the existing pile driver is driving pipe piles, the pipe piles are prone to deviation during the hammering process due to the different softness of the ground, and some vehicle bodies may shake due to the knocking, which can easily cause a large deviation in the piling position; 2. Due to the complexity of the mine terrain, some piling equipment has an anti-drift structure at the front end but it cannot be folded, causing the vehicle body surface to protrude, making it inconvenient to move the vehicle body and easily causing wear on the surface of the parts.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5The utility model provides a technical solution: a pile driver with an anti-deviation structure, including a body 1, side panels 2 are welded at both ends of the body 1, the bottoms of the side panels 2 are respectively connected to hydraulic columns 3 by bolts, support components 4 are respectively provided inside the side panels 2, a column 5 is welded at one end of the surface of the body 1, a pulley component 6 is provided on the surface of the column 5, the column 5 is slidably connected to a gravity block 7 through a sliding rod provided thereon, the pulley component 6 is connected to the gravity block 7 by a rope, hydraulic telescopic rods 8 are respectively provided at both ends of the outer wall of the column 5, an anti-deviation component 9 is rotatably connected to one side of the body 1, and the top of the anti-deviation component 9 is rotatably connected to one end of the hydraulic telescopic rod 8.

[0025] The supporting assembly 4 includes a driving gear 401 and a driven gear 402. The driving gear 401 and the driven gear 402 are respectively rotatably connected to the inside of the side plate 2. The driven gear 402 is respectively meshed and connected to the two ends of the driving gear 401. The driving gear 401 is installed with a sprocket assembly 403 through a shaft rod passing through the axis center thereof, and the driving gears 401 are connected through the sprocket assembly 403.

[0026] The pulley assembly 6 includes a first pulley 601, a second pulley 602 and a third pulley 603. The first pulley 601 and the second pulley 602 are respectively rotatably connected to the two ends of the outer wall of the column 5, the second pulley 602 is located above the first pulley 601, and the third pulley 603 is respectively rotatably connected to one side of the outer wall of the gravity block 7. The first pulleys 601 are coaxially connected and an A gear 604 is provided on the surface of the shaft body, and the A gear 604 is meshed with a B gear 605.

[0027] The anti-deviating component 9 is internally rotatably connected with a reverse lead screw 901 , and the surface of the reverse lead screw 901 is respectively threadedly connected with a reverse nut 902 , and the reverse nuts 902 are respectively welded with a limiting plate 903 .

[0028] In this embodiment, Figure 2As shown, the driving gear 401 and the driven gear 402 form a rotation motion through the sprocket assembly 403, and the inner wall of the driven gear 402 is respectively threadedly connected with a buried depth column 404, and the bottom of the buried depth column 404 is conical; since the pile driver realizes the burying of the pile nail into the ground by continuously hitting the top of the pile head, the stability of the vehicle body 1 also plays a vital role. When working on some unstable or soft soil ground, the front end gravity block 7 is constantly hitting, which may cause the vehicle body 1 to shake, which will affect the effect of piling. By adding the support components 4 on both sides and using the servo motor The two sets of sprocket assemblies 403 are driven to rotate, and then the driving gear 401 drives the driven gear 402 to rotate respectively. The threaded structure on the inner wall of the driven gear 402 and the surface of the buried depth column 404 can enable the driven gear 402 to achieve the purpose of pushing the buried depth column 404 up and down under the rotation movement. The buried depth column 404 is pushed spirally into the soil using the force of rotation. The front conical surface can reduce the contact surface area between the rotating structure and the soil, thereby reducing the friction resistance during the pushing process, making it easier to pass through the soil layer. At the same time, this shape is also very suitable for rocks, soil and sandy layers.

[0029] In this embodiment, Figure 1 and Figure 2 As shown, a cavity for threaded connection of the buried depth column 404 is provided inside the side plate 2, and the buried depth column 404 is lifted and lowered inside the side plate 2 through the driven gear 402; the buried depth column 404 can be inserted into the soil layer during continuous rotation, thereby increasing the bearing capacity of the vehicle body 1 on the ground, thereby achieving stability in the entire piling process, improving the operability of the equipment, and making it more suitable for the complex terrain environment of mines.

[0030] In this embodiment, Figure 3 and Figure 4As shown, the first pulley 601, the second pulley 602 and the third pulley 603 are connected by steel wire ropes, and the ropes are in a folding structure on the surface of the first pulley 601 through gear A 604 and gear B 605, and the gravity block 7 forms a lifting movement at the bottom of the column 5 and the top of the anti-deviation component 9, and the axis point of the gravity block 7 and the axis point between the limit plate 903 are in the same vertical center line; currently, most pile driving uses the method of burning diesel, which achieves an ideal effect but has many disadvantages. The exhaust gas generated by burning diesel will emit a large amount of harmful substances, and the engine noise generated during operation is relatively large, which will cause noise pollution to the surrounding environment and residents. The internal parts include engine oil, spark plugs and other parts, which need regular maintenance and servicing, which undoubtedly increases the maintenance cost. Through the structure of an array of pulleys, steel ropes and a gravity block 7, the pile nails are buried by utilizing the gravity structure. The mechanical structure is simple and the operating cost is low. While greatly reducing the maintenance cost, it effectively improves the environmental protection. The gravity block 7 slides under the column 5 through a slide rod, and the axis point of the gravity block 7 and the lower limit plate 903 are kept on the same vertical center line, which helps to reduce the deviation or swing during the piling process, ensures the vertical transmission of force during the piling process, and makes the knocking force act more concentratedly on the surface of the pile nail, thereby improving the efficiency and accuracy of the knocking and effectively avoiding the possibility of the pile nail deviating.

[0031] In this embodiment, Figure 1 and Figure 5 As shown, the anti-drift component 9 forms a flip structure under the column 5 through the hydraulic telescopic rod 8; the anti-drift component 9 is folded and folded on the surface of the vehicle body 1 through the flip structure, so that the vehicle body 1 is more convenient to move. Due to the high undulation of the mine terrain, if the front-end objects cannot be folded or collision occurs, wear and tear will affect the subsequent use effect and increase the maintenance cost. It can also reduce potential dangers during the operation process, such as reducing the possibility of workers being hit by the anti-drift component 9, thereby improving operation safety.

[0032] In this embodiment, Figure 5 As shown, the limit plates 903 are slidably connected to the limit grooves provided on the surface of the anti-deviation component 9 through the reverse nuts 902, and the limit plates 903 move toward each other; the distance between the limit plates 903 can be adjusted through the transmission structure of the reverse screw 901 and the reverse nut 902, which can be applied to piles of different diameters and shapes, and has strong versatility and adaptability. The piles are clamped by the limit plates 903, which effectively reduces the shaking and swaying of the piles during the piling process, causing the problem of deviation.

[0033] The use method and advantages of the utility model: When the pile driver with an anti-deviating structure is used, the working process is as follows:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, the vehicle body 1 is moved to the construction site, and the corresponding stable structure is selected according to the ground environment. If the ground environment is a relatively flat hard bottom surface, the hydraulic column 3 is driven to lower it to the ground to provide stable support force. For uneven gravel or soil layers, the sprocket assembly 403 can be driven by a servo motor to drive the driving gear 401 to rotate, and then the driven gear 402 can be rotated to make the buried depth column 404 rotated under the threaded structure and pushed into the ground, thereby increasing the stability of the vehicle body 1. After the pile nails are transported to the construction site by the lifting equipment, the anti-deviation assembly 9 is rotated by the push of the hydraulic telescopic rod 8. According to the diameter of the pile nails, the driving power servo motor drives the reverse screw 901 to rotate. The reverse nuts 902 drive the limit plates 903 to move toward each other until they are attached to the surface of the pile nail. The B gear 605 is driven by the motor to rotate the A gear 604 and then the first pulley 601. The steel rope is wound up by the rotating structure. While the rope is wound up, the gravity block 7 rises. It should be noted that the pulley block does not have a self-locking structure. The first pulley 601 is rotated by the rotating structure of the A gear 604 and the B gear 605. Therefore, the winding structure can be used to realize the rise of the gravity block 7. When the driving structure is lost, due to gravity, the gravity block 7 falls freely vertically to the top of the pile nail under the action of gravity. The piling process is realized by this reciprocating structure.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
