Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of infrastructure, especially relates to a pile pressing crossbeam assembly for static pressure pile planting machine. BACKGROUND

[0002] The pile planting machine is a special engineering machinery for implanting pile bodies (such as concrete piles, steel piles, etc.) into the ground in construction, traffic and other engineering, and mainly presses or drives the pile bodies into the foundation by static pressure, impact and other ways to enhance the bearing capacity of the foundation or support the foundation structure. The pile planting machine is usually large in size and includes a power system, a pile frame, an operating device (such as a static pressure pile planting device), etc. Due to the overall height, the pile planting machine needs to be disassembled for transportation.

[0003] The static pressure pile planting device is one of the core operating components of the static pressure pile planting machine and other types of pile planting machines, and mainly functions to stably press the pile body into the ground by transmitting pressure. The static pressure pile planting device mainly includes a pile pressing crossbeam assembly, a lifting clamping seat, a guide device, and a static pressure cylinder (such as a pneumatic cylinder or a hydraulic cylinder). The lifting clamping seat is arranged inside the pile pressing crossbeam assembly, the guide device is arranged between the lifting clamping seat and the pile pressing crossbeam, and the static pressure cylinder is arranged on the top of the pile pressing crossbeam assembly, with a piston rod connected to the lifting clamping seat.

[0004] In the static pressure pile planting device, four high static pressure cylinders are connected to the pile pressing crossbeam assembly, and the lifting clamping seat is driven to move downward and upward by the extension and retraction of the static pressure cylinders to realize the static pressure operation on the pile body. Due to the high height of the structure formed by the pile pressing crossbeam assembly and the static pressure cylinders, the static pressure cylinders need to be disassembled for transportation. The disassembly and assembly of the static pressure cylinders require the operation of multiple sets of fastening bolts, which is extremely time-consuming. In addition, the vertical installation precision of the static pressure cylinders is required to be high, and it is difficult to ensure the installation precision on the construction site. Therefore, in order to improve the disassembly and assembly efficiency of the static pressure cylinders and ensure the installation precision of the static pressure cylinders, the present case is generated. CONTENT OF THE UTILITY MODEL

[0005] Therefore, in view of the above problems, the utility model provides a pile pressing crossbeam assembly for a static pressure pile planting machine for improving the disassembly and assembly efficiency and ensuring the installation precision of the static pressure cylinder.

[0006] To solve the above technical problems, the utility model adopts the following solution: a pile pressing crossbeam assembly for a static pressure pile planting machine, which includes a bottom plate, four vertical columns arranged on the bottom plate, and two crossbeams arranged on the top of the vertical columns. The two ends of the two crossbeams are arranged on the top of the four vertical columns, respectively. A disassembly and assembly structure for convenient disassembly and assembly is arranged between the end of the crossbeam and the top of the vertical column. A retracting cylinder for retracting the extension rod of an external static pressure cylinder is arranged inside the crossbeam. The retracting cylinder is fixedly arranged inside the crossbeam. Upper and lower openings are arranged on the upper and lower surfaces of the crossbeam, respectively, and are in communication with the retracting cylinder. The retracting cylinder, the upper opening, and the lower opening form a retracting channel.

[0007] Further improvement is that the dismounting structure comprises a plug-in plate, a plug-in groove, and a connecting piece, the plug-in plate is fixedly arranged on the lower surface of the two ends of the cross beam, the plug-in groove is arranged on the top of the stand column, the plug-in plate and the sidewall of the plug-in groove are both provided with connecting holes, the plug-in plate is attached to the inner wall of the plug-in groove, and the connecting piece is inserted into the connecting hole.

[0008] Further improvement is that the connecting piece comprises an outer rod, an inner rod, and a fixing sheet, the inner part of the outer rod is provided with a threaded channel, the inner rod is provided with a threaded rod which is screwed with the threaded channel, the outer wall of the outer rod is attached to the hole wall of the connecting hole, the outer end of the outer rod is provided with a fixing groove which is perpendicular to the axis, and the fixing sheet is inserted into the fixing groove on one side, and the fixing sheet is dismountably fixed on the outer wall of the stand column.

[0009] Further improvement is that the stand columns are provided with reinforcing plates for increasing the installation strength of the stand columns, the lower end of the reinforcing plate is fixed on the bottom plate, and the two sides are fixed on the outer wall of the stand column.

[0010] Further improvement is that the two ends of the cross beam are provided with inclined surfaces which can prevent the impact deformation during hoisting, and the inclined surfaces are fixedly provided with hoisting rings.

[0011] Further improvement is that the upper surface of the cross beam is fixedly provided with a mounting flange plate at the upper opening.

[0012] Further improvement is that the two sides of the bottom plate are respectively provided with sliding plates which are matched with external sliding rails, and the sliding plates are fixedly arranged on the lower end of the stand column.

[0013] By adopting the foregoing technical scheme, the utility model has the advantages of: 1. In the prior art, the static pressure cylinder and the pile pressing cross beam assembly are transported to the site for assembly, the assembly precision of the static pressure cylinder and the dismounting of the bolts are relatively time-consuming, and the dismounting of the static pressure cylinder is complicated. In the case, the cross beam and the stand column are dismountable, the cross beam can be dismounted together with the static pressure cylinder from the stand column, and the static pressure cylinder does not need to be dismounted during transportation. Before dismounting, the telescopic rod of the static pressure cylinder is retracted into the hidden cylinder, which is beneficial to protecting the telescopic rod and the parts thereon and facilitating the direct placement of the dismounted cross beam on the ground. In the prior art, when the static pressure cylinder is dismounted alone, the four static pressure cylinders need to be fixed to prevent rolling and impact during transportation, and in the case, the static pressure cylinder is dismounted together with the cross beam, the placement of the cross beam on the ground limits the rolling displacement of the static pressure cylinder, and the dismounted cross beam and static pressure cylinder are fixed during transportation.

[0014] 2、The dismounting structure of the connecting piece matched by the plug-in plate and the plug-in groove in the case can only disengage the connecting piece to complete the disassembly of the cross beam and the stand by dismounting the fixed sheet, and can realize stable connection by fixing the fixed sheet and tightening the inner rod during installation, compared with the dismounting mode of the traditional multiple fastening bolts, greatly simplifying the operation steps, greatly shortening the dismounting time of the stand and the cross beam, and reducing the on-site construction waiting period.

[0015] 3、The inclined surface at both ends of the cross beam in the case avoids impact deformation during hoisting, the hoisting hanging ring facilitates quick hoisting and dismounting, and reduces the operation difficulty and labor cost during dismounting.

[0016] 4、The reinforcing plate arranged at the lower end of the stand in the case strengthens the connection strength of the stand and the bottom plate, and also strengthens the connection strength between the stands, which is beneficial to improve the installation strength of each stand after the cross beam is dismounted.
