Description

Technical Field

[0001] The utility model belongs to the technical field of pile driving devices, and particularly relates to a pile driving device for municipal engineering. Background Technique

[0002] The pile driving devices used in municipal engineering are usually used to drive or install pile foundations. Impact pile driving is often adopted, and its principle is to use a heavy hammer or impact head to drive the pile foundation into the ground by dropping the weight to impact the pile head. Impact pile driving is suitable for various types of soils and can operate under different construction site conditions.

[0003] The existing pile driving devices for municipal engineering have the following disadvantages during use:

[0004] Generally, a limiting structure is used to vertically position the pile foundation below the heavy hammer or impact head, and then the heavy hammer or impact head falls by gravity to realize the pile driving action on the pile foundation. However, a moving structure is often adopted at the bottom of the pile driving device, and universal wheels are generally set to facilitate the movement of the pile driving device. However, there is no stable structure on the pile driving device that is linked with the limiting structure, resulting in instability during the pile driving process and greatly reducing the pile driving efficiency. Therefore, a pile driving device for municipal engineering is needed. Content of the Utility Model

A pile driving column slides inside the fixed cylinder. A pull rope is fixedly connected to the top of the pile driving column. The other end of the pull rope sequentially bypasses a guide rope assembly b and a guide rope assembly a and is fixedly connected to the outer side of a winding drum. The guide rope assembly b and the guide rope assembly a are respectively installed on the Z-shaped support frame. The winding drum is rotatably connected inside a storage box through a transmission shaft. An opening is provided at the top of the storage box. The storage box is fixedly connected to the top end position of the Z-shaped support frame close to the rollers.

The output shaft of the driving motor extends into the storage box and is fixedly connected to the mounting shaft hole of the gear b.

[0011] As a preferred embodiment, the manual clamping and limiting structure includes two symmetrically arranged clamping arms located below the pile driving column.

The two sliding seats are both slidably connected to sliding grooves provided on the Z-shaped support frame.

[0012] As a preferred embodiment, a bidirectional screw is threadedly connected to the two sliding seats. Both ends of the bidirectional screw are rotatably connected to the sliding grooves.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present utility model in conjunction with embodiments.

[0022] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present utility model in conjunction with the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0023] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of protection of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement to the method of the present utility model under the premise of the concept of the present utility model belongs to the scope of protection required by the present utility model.

[0024] Embodiment

[0025] Generally, a limiting structure is used to vertically position the pile foundation below the heavy hammer or impact head, and then the heavy hammer or impact head falls by gravity to achieve the pile driving action of the pile foundation. However, a moving structure is often adopted at the bottom of the pile driving device, and universal wheels are generally set to facilitate the movement of the pile driving device. However, there is no stable structure on the pile driving device that is linked with the limiting structure, resulting in instability during the pile driving process and greatly reducing the pile driving efficiency.

[0026] Therefore, please refer to Figures 1-3 , the present utility model provides a pile driving device for municipal engineering, including: a Z-shaped support frame 1. Rotating rollers 12 are connected to the four circumferences at the bottom end of the Z-shaped support frame 1. A through-round opening is provided at a position on the top of the Z-shaped support frame 1 away from the rollers 12. A fixed cylinder 42 is fixedly connected inside the through-round opening. A pile driving column 41 slides inside the fixed cylinder 42. A pulling rope 4 is fixedly connected to the top of the pile driving column 41. The other end of the pulling rope 4 sequentially bypasses the guide rope assembly b3 and the guide rope assembly a2 and is fixedly connected to the outside of the rope winding cylinder 52. The guide rope assembly b3 and the guide rope assembly a2 are respectively installed on the Z-shaped support frame 1. The rope winding cylinder 52 is rotatably connected to the storage box 5 through a transmission shaft 51. An opening is provided at the top of the storage box 5. The storage box 5 is fixedly connected to the Z-shaped support frame 1 at the top position close to the rollers 12. Two symmetrically arranged pushing hand rods 11 fixedly connected to the Z-shaped support frame 1 are further provided at the rear side of the storage box 5.

[0027] The guide rope assembly b3 and the guide rope assembly a2 have the same structure, both adopting the structure of an upper guide wheel and a lower guide wheel. As can be seen from the structure in the drawings, it can effectively ensure the stability of the pulling rope 4 during movement.

[0028] It further includes an intermittent lifting structure 6, a manual clamping and limiting structure 7, and a linkage type stabilizing structure 8. The intermittent lifting structure 6 is installed on the storage box 5 and is connected to the outside of the transmission shaft 51.

[0029] The manual clamping and limiting structure 7 is installed on the Z-shaped support frame 1 and is located below the driving pile 41;

[0030] The linkage stabilizing structure 8 is installed on the Z-shaped support frame 1 and is connected to the manual clamping and limiting structure 7.

[0031] Furthermore, as Figures 1-3 shown, it is specifically noted that the intermittent lifting structure 6 includes a gear a61, which is fixedly connected to the outside of the transmission shaft 51. The gear a61 is located on one side of the rope winding drum 52. A gear b62 is meshed and connected to the outside of the gear a61. The gear b62 is a sector gear. A driving motor 63 is fixedly connected to the right side wall of the storage box 5. The output shaft of the driving motor 63 extends into the storage box 5 and is fixedly connected to the mounting shaft hole of the gear b62.

[0032] In the state where the gear b62 in the attached drawing just rotates counterclockwise and is about to disengage from the gear a61, the rope winding drum 52 is urged to lift the driving pile 41 to a certain height. When the gear b62 disengages from the gear a61, under the action of gravity, the driving pile 41 can move downward under gravity.

[0033] Furthermore, as Figures 1-3 shown, it is specifically noted that in order to clamp and limit the pile, and ensure that the pile will not tilt during the driving process, a manual clamping and limiting structure 7 is provided, which includes two symmetrically arranged clamping arms 71 located below the driving pile 41. Arc-shaped openings 72 for clamping and limiting an external pile are formed on the opposite side walls of the two clamping arms 71. Vertical cross-section I-shaped sliding seats 73 are fixedly connected to one ends of the two clamping arms 71 facing the storage box 5. The two sliding seats 73 are both slidably connected to sliding grooves provided on the Z-shaped support frame 1. A bidirectional screw 74 is threadedly connected to the two sliding seats 73. Both ends of the bidirectional screw 74 are rotatably connected to the sliding grooves. One end of the bidirectional screw 74 extends to the outside of the Z-shaped support frame 1 and is fixedly connected to a handwheel 75.

[0034] Furthermore, as Figures 1-3As shown in the figure, it is worth specifically explaining that in order to be able to clamp and limit the pile column while operating the above-mentioned manual clamping and limiting structure 7, and at the same time strengthen the stability between the entire device and the ground, a linkage type stabilizing structure 8 is provided, including limiting sleeves 83 fixedly connected to the outer periphery of the outer wall near the bottom of the Z-shaped support frame 1. The four limiting sleeves 83 are all movably sleeved on the outside of the same H-shaped lifting frame 81. Fixing plates 82 are fixedly connected to the four corners of the bottom end of the H-shaped lifting frame 81. A plurality of tapered blocks are fixedly connected to the bottom end of each fixing plate 82. Two symmetrically arranged inclined slots 84 are opened on one side wall of the H-shaped lifting frame 81 close to the sliding seat 73. Transmission columns 85 are movably inserted into the inclined slots 84. The ends of the two transmission columns 85 facing away from the storage box 5 are fixedly connected to the outside of the sliding seat 73.

[0035] The width of the inclined slot 84 is equal to the diameter of the transmission column 85.

[0036] In summary: When using this pile driving device for municipal engineering, first hold the pile column upright between the two arc-shaped openings 72, and rotate the bidirectional screw rod 74 through the hand wheel 75, so that the two clamping arms 71 move towards each other, and the two arc-shaped openings 72 clamp and limit the outside of the pile column. In addition, during the process of the two clamping arms 71 moving towards each other, the transmission columns 85 connected to the two sliding seats 73 also move towards each other. Combined with the cooperative design of the inclined slots 84, the outer periphery of the H-shaped lifting frame 81 slides down on the four limiting sleeves 83, so that a plurality of tapered blocks at the bottom end of each fixing plate 82 can be inserted into the soil to ensure the stability of the pile driving operation of this pile driving device. After that, the driving motor 63 can be started, and the driving gear b62 rotates counterclockwise, so that the gear b62 intermittently drives the gear a61, and the rope winding cylinder 52 winds up the pulling rope 4. When the gear b62 does not mesh and drive the gear a61, the pile driving column 41 can move up a certain height and then fall freely in the fixed cylinder 42 by gravity to realize the hammering of the pile column below, thus greatly improving the pile driving efficiency.
