Description

Technical Field

[0001] The utility model relates to the technical field of cross pile protection steel drill devices, in particular to an automatic wire-reeling cross pile protection device. Background Art

[0002] Pile foundations are widely used in housing construction, municipal engineering, and highway engineering. Bored piles, in particular, are the most common foundation structure in highway bridges, serving as the substructure for bridge piers and abutments. The standard tolerance for centerline plane error in pile foundation construction is ≤50mm for a single pile and ≤100mm for a group of piles. This misalignment directly impacts the accuracy of the pile superstructure.

[0003] According to the requirements of the highway bridge and culvert regulations and the bored cast-in-place pile construction regulations, before drilling the pile foundation, the pile position needs to be marked out, and then the point position is led out with cross guard piles to facilitate precise control of the pile position. During the current construction process, the cross guard piles for pile foundation construction mostly use steel bar heads or wooden piles as cross guard piles for pile foundation construction, and the cross lines are tied and set. There are the following technical defects: the cross guard piles are easy to loosen, the binding positions of the cross guard pile harnesses are inconsistent before and after untying and restoring, and the cotton thread and nylon thread used on site have the disadvantages of elasticity and easy displacement. The above will lead to errors in the center point of the cross guard pile, resulting in the inability to guarantee the plane error of the pile foundation construction. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a cross pile protection device with automatic winding, thereby improving the pile position plane error in pile foundation construction and reducing the amount of measurement and centering work during pile foundation construction.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Example 1:

[0020] like Figure 1 As shown, a cross pile guard device with automatic wire winding includes a pair of galvanized steel chisels 1, a wire winding and releasing mechanism provided on any one of the steel chisels 1, and a wire fixing mechanism provided on the other steel chisel 1, the wire winding and releasing mechanism including a wire winding drum 4 provided on the steel chisel 1, a galvanized steel wire 3 provided on the wire winding drum 4, the wire winding drum 4 is connected to the steel chisel 1 through a wire winding drum fixing frame 7, the wire winding drum fixing frame 7 is provided with a wire position constraint hole 5, the steel wire 3 passes through the wire position constraint hole 5, the end of the steel wire 3 is provided with a hook 6, and a spring spring 2 is provided in the wire winding drum 4; a hanging ear 9 is provided on the other steel chisel 1, and a hook hole 8 is provided on the hanging ear 9, and the hook hole 8 is used to connect with the hook 6.

[0021] After the pile center is determined during on-site pile foundation construction, a pair of steel chisels are used as a set of devices, with two sets of devices placed in a cross pattern. The galvanized steel chisel 1 is nailed to the center of the pile, not in an area that affects the construction range of the pile foundation, ensuring that the galvanized steel chisel 1 is firmly nailed. The hook 6 is used to pull out the galvanized steel wire 3 stored on the steel chisel's take-up drum 4, ensuring that the galvanized steel wire 3 coincides with the center of the pile. The hook 6 is hung on the hook hole 8 on the steel chisel's hanging ear 9. The contraction force of the spring 2 will keep the galvanized steel wire 3 taut and straight, and the line constraint hole 5 will fix the position of the galvanized steel wire 3 and prevent it from moving. After removing the hook 6, the contraction force of the spring 2 will automatically retract the galvanized steel wire 3 onto the take-up drum 4. When it is pulled out again, as long as the position of the steel chisel has not shifted or rotated, the forward and backward pulling position will not change. The two sets of devices are arranged in a cross pattern to ensure that the intersection of the cross lines coincides with the center of the pile.

[0022] Example 2:

[0023] like Figure 2 As shown, the same points as Example 1 are not repeated here. The differences are:

[0024] The end of the steel drill 1 is provided with an anti-rotation mechanism, which is composed of a number of triangular baffles 10. The baffles 10 are evenly arranged on the outer peripheral side of the end of the steel drill 1. The side of the baffle 10 away from the steel drill 1 is flush with the tapered surface at the end of the steel drill 1. When the steel bars are driven downward, the triangular baffles 10 reduce the resistance. The baffle 10 is used to prevent the steel drill 1 from rotating. The steel drill 1 is composed of an upper steel drill 11 and a lower steel drill 12, which are connected by a thread. After the first laying of the wire is completed, the upper steel drill 11 can be removed to prevent obstruction of construction. A sleeve 13 is fixed on the outer peripheral side of the threaded part of the lower steel drill 12. The sleeve 13 is used to protect the threaded part from mud and sand entering and obstructing the threaded connection. A downward tapered surface is provided between the lower end of the sleeve 13 and the lower steel drill 12. The tapered surface is used to reduce the resistance when the steel drill 1 is driven in.

[0025] After the steel drill 1 is driven into the designated position, the driving is stopped at the sleeve 13 so that the upper half of the sleeve 13 is exposed to the base layer. After the wire drawing is completed, the upper steel drill 11 is rotated and removed to prevent obstruction of construction.

[0026] Example 3:

[0027] like Figure 3 As shown, the same points as Example 1 are not repeated here. The differences are:

[0028] The steel drill 1 is also equipped with an anti-tilt mechanism. This mechanism comprises a cross-shaped rod 14 with a ring 15 at its center, within which the steel drill 1 is positioned. Vertically downward-pointing steel spikes 16 are located at each of the four ends of the cross-shaped rod 14. After the steel drill 1 is driven into the designated position, the anti-tilt mechanism is inserted into the steel drill 1 until it reaches the surface of the base layer, and the steel spikes 16 are driven into the base layer to prevent the steel drill 1 from tilting due to external forces.

[0029] After the steel drill 1 is nailed into the designated position, the ring 15 on the cross rod 14 is inserted into the steel drill 1, and the steel nails 16 at the four corners are nailed into the base to prevent the steel drill 1 from tilting.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
