[0001] The utility model relates to the technical field of auxiliary platforms for pile drivers, and more specifically to an auxiliary construction platform device for a drilling pile driver. Background Art

[0002] A pile driver is a pile driving machine that uses impact force to drive piles into the ground.

[0003] For example, in the patent CN202157326U, an auxiliary construction platform device for a drilling pile driver is disclosed, which includes a transverse steel beam, a longitudinal steel beam, a leg steel pipe, a platform steel plate, and an inclined support angle iron. This device consists of three parts: a platform component, a vertical support component, and an inclined support component. The transverse steel beam, the longitudinal steel beam, and the platform steel plate form the platform component. One end of the platform component straddles the high-level ground, and the other part presses on the vertical support component. The bottom of the vertical support component is supported on the low-level ground, so that the load of the drilling pile driver and the upper platform component can be transmitted to the low-level ground in the high-low difference area. This device has a simple structure, is convenient for construction and installation, is firm and durable, can be disassembled, moved, reused, and saves resources. The component assembly can be standardized and is convenient for popularization and application.

[0004] In the actual operation process, most drilling pile drivers will shift their positions during the drilling and piling process due to continuous vibration, and it is impossible to buffer the entire machine of the pile driver.

[0005] It can be seen that the above problems existing in the prior art need to be improved urgently. Summary of the Utility Model

[0007] To achieve the above object, an auxiliary construction platform device for a drilling pile driver provided by the present utility model includes an auxiliary platform assembly. A pile driving assembly is inserted and slidably arranged inside the auxiliary platform assembly. An expansion and abutment mechanism distributed in a circumferential array is arranged inside the auxiliary platform assembly. The expansion and abutment mechanism abuts against the outer wall of the pile driving assembly.

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] As Figure 1-2 shown, an auxiliary construction platform device for a drilling pile driver includes an auxiliary platform component 1. A piling component 2 is inserted and slidably arranged inside the auxiliary platform component 1. An expansion and abutting mechanism distributed in a circumferential array is arranged inside the auxiliary platform component 1. The expansion and abutting mechanism abuts against the outer wall of the piling component 2. The piling component 2 is driven to maintain vertical reciprocating motion to drive the expansion and abutting mechanism to maintain elastic expansion and contraction.

[0025] The main purpose of the auxiliary construction platform device for the drilling pile driver is that the support column 103 slidably abutted against the outer wall of the sleeve 201 and the elastic telescopic sleeve 104 sleeved on its outer wall can buffer the force generated by the up and down movement of the pile driver during the piling process. And the integral molding at the bottom of the platform housing 101 can increase the contact area with the ground, making it more stable, reducing the ground stress pressure, and avoiding the loosening and collapse of the land around the drilling and piling area. Also, through the through groove 107 provided at the bottom of the platform housing 101, the soil vibrated by the drilling and piling can enter the inside of the first inner groove 102, increasing the weight of the auxiliary platform component 1 and pressing the underlying land, avoiding the loosening and collapse of the land around the drilling and piling area.

[0026] In the technical solution provided by the present utility model, from Figure 1 and Figure 2 it can be seen that the auxiliary platform component 1 includes a platform housing 101. The integral molding at the bottom of the platform housing 101 is connected to the ground, which can increase the contact area, avoid the loosening and collapse of the land around the drilling and piling area. And a first inner groove 102 is opened inside the platform housing 101, which can collect the soil extruded by the drilling and piling, thereby increasing the weight of the entire auxiliary platform component 1, further stabilizing the auxiliary platform component 1, and further pressing the bottom soil. And the top and bottom of the platform housing 101 are correspondingly provided with piling grooves 106 that are opposite to each other to clamp the piling component 2.

[0027] Furthermore, the telescopic abutting mechanism specifically includes support columns 103 that are inclined. A slider 105 is provided at the end of the support column 103 close to the pile driving assembly 2. When the pile driver reciprocates up and down inside the pile driving assembly 2 to perform pile driving work, and drives the pile driving assembly 2 to reciprocate vertically, the pile driving assembly 2 is kept stable at all times by sliding along with the support column 103.

[0028] Furthermore, elastic telescopic sleeves 104 are provided inside each support column 103, and the elastic telescopic sleeves 104 are assembled to drive the support columns 103 to elastically contract. When the pile driver reciprocates up and down inside the pile driving assembly 2 to perform pile driving work, it can drive the pile driving assembly 2 to reciprocate up and down, thereby performing elastic buffering through the elastic telescopic sleeves 104 to avoid damage to the auxiliary platform assembly 1.

[0029] Furthermore, through grooves 107 distributed in an array are formed at the bottom of the platform housing 101, and each through groove 107 communicates with the first inner groove 102. The soil discharged due to drilling and pile driving work can enter the inside of the first inner groove 102 from the through grooves 107, which can increase the total weight of the platform housing 101, and then press the bottom soil heavily, avoiding the loosening and collapse of the land around the drilling and pile driving area, and also preventing the dust and soil from pile driving from scattering in the external air and polluting the air.

[0030] Furthermore, the pile driving assembly 2 includes a sleeve 201 that slides inside the pile driving groove 106. Sliding grooves 203 are formed on the outer wall of the sleeve 201 corresponding to each support column 103, and the slider 105 is slidably clamped inside the sliding grooves 203, enabling the sleeve 201 to perform a force unloading and buffering work during the up and down reciprocating motion when the pile driver inserted inside it performs pile driving work.

[0031] Furthermore, a second inner groove 202 is formed inside the sleeve 201 to insert the pile driver.

[0032] Working principle: First, insert the pile driver into the inside of the second inner groove 202. By performing pile driving work with the pile driver, the sleeve 201 can be subjected to a vertically reciprocating force, and thus perform synchronous vertical reciprocating motion;

[0033] When the sleeve 201 performs vertical reciprocating motion, each support column 103 that slides and abuts against the outer wall of the sleeve 201 inside the platform housing 101 will be subjected to a downward extrusion force, and then through the elastic telescopic sleeve 104 sleeved on the outer wall of the support column 103, elastic buffering and force unloading can be performed;

[0034] When the pile driver continuously performs pile driving work, the soil discharged from the drilled pile can be discharged into the interior of the first inner groove 102 through the through groove 107, thereby increasing the total weight of the platform housing 101, and then pressing the bottom soil, avoiding the loosening and collapse of the land around the drilled pile area, and also preventing the flying of the dust and soil of the pile driving in the external air and polluting the air.

[0035] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
