Description

Technical Field

[0001] The present invention relates to the technical field of ancient building restoration, and particularly relates to a cutting device for the root of the eaves column. Background Art

[0002] With the development of the economy and the improvement of living standards, people are becoming more and more interested in the historical culture and national characteristics of our country. Historical ancient towns and villages have become hot spots for tourism and leisure, and then the development and restoration of ancient buildings have become an important part of the construction field;

[0003] Among them, the damage of wooden ancient buildings includes root decay of columns, splitting and breaking of column bodies, bending and sagging of purlins, decay, bending and missing of crossbeams, etc. There are generally two treatment methods for root decay of columns. One is column root inlay, and the other is butt joint. For column root inlay, the decayed part outside the column core needs to be removed, and then the inlay material is used to surround the column core. When the decay depth of the eaves column exceeds half of the column cross-section, or the column core decays and the decay height accounts for 1 / 5 to 1 / 3 of the column height, the butt joint method is adopted;

[0004] And the current method for removing the decayed part of the root of the eaves column is to set up an external scaffold and then manually use a large plane and a medium plane to scrape and round it for removal. The operation is cumbersome and the accuracy control is poor, and the efficiency of removing the decayed part of the column root and performing inlay and butt joint operations is low.

The tool set 4 includes a tool tip 41 and a tool body 42. A slide groove I 411 is penetrated through the lower end of the tool tip 41. A pair of engaging mechanisms 5 are symmetrically arranged between the tool tip 41 and the tool body 42. A pair of gear shapers I 43 fixed on the tool set 4 are arranged on the upper side of the engaging mechanism 5. The lower end face of the gear shaper I 43 is inclined, and the length of the gear shaper I 43 on the right side is greater than the length of the gear shaper I 43 on the left side. The right side surfaces of the pair of gear shapers I 43 are in the same vertical plane as the right side surfaces of the engaging block I 51 and the engaging block II 52 respectively;

[0032] The engaging mechanism 5 includes an engaging block I 51 and an engaging block II 52. A through hole I 511 is provided in the middle of the engaging block I 51 and the engaging block II 52. Engaging portions I 512 are provided on the upper and lower sides of the engaging block I 51. The horizontal portions of the engaging portions I 512 are located on the upper and lower sides of the engaging block II 52, forming a sum of the heights of the engaging block I 51 and the engaging portions I 512 in the vertical direction greater than the height value of the engaging block II 52, facilitating the cooperation between the gear shaper I 43 on the right side and the engaging block II 52. Engaging portions II 521 are provided on the left and right sides of the engaging block II 52. The thickness of the engaging portions II 521 is greater than that of the engaging portions I 512. The engaging block I 51 is sleeved inside the engaging block II 52, and the edges of the engaging portions I 512 are engaged with the edges of the engaging portions II 521. A spring 53 is provided between the engaging block I 51 and the engaging block II 52. A through hole II 513 is horizontally provided on the engaging block I 51. A through hole III 522 is horizontally provided on the engaging block II 52 at a position outside the through hole II 513. After the tool head 41 is bent 90° toward the middle, the gear shaper I 43 on the left side passes through the through hole III 522 and cooperates with the engaging block I 51. Two pairs of horizontal shafts 523 are provided on the right wall of the engaging block II 52.

[0033] A tool groove 421 is obliquely and penetratingly provided in the left part of the tool body 42. A planer blade 422 is provided in the tool groove 421. A fixing socket 44 is provided at the bottom of the tool body 42 and the middle of the tool head 41.

[0034] Two pairs of extending portions 423 are provided at the top end of the tool body 42. A pair of through holes I 4231 are provided on the extending portions 423, and the horizontal shafts 523 on the same side are inserted into the through holes I 4231.

[0035] A fixing shaft I 4232 is provided outside the extending portion 423. The fixing shaft I 4232 is inserted into the through hole I 511 of the engaging block I 51 and the engaging block II 52 and extends outside the sliding groove I 411. The tool head 41 slides up and down or back and forth in the sliding groove I 411 to engage the gear shaper I 43 with the engaging mechanism 5. A vertical limiting shaft 4233 is provided in the middle of the fixing shaft I 4232. The right side wall of the limiting shaft 4233 is an arc-shaped smooth surface, so that when the tool head 41 is in the vertical position, the limiting shaft 4233 restricts the lateral movement of the engaging block I 51 during the lateral movement process. When the tool head 41 is in the horizontal position, the limiting shaft 4233 can pass through the through hole II 513 to facilitate the lateral movement of the engaging block I 51.

[0036] A number of arc-shaped chutes II 311 are provided through the turntable 31, and the top of the chute II 311 expands outward. A bracket 32 is provided on the lower side of the turntable 31. The bracket 32 has a number of extension ends 321. By inserting the extension ends 321 into the through holes II 4241, when the fixed shaft III 424 slides along the chute II 311, the orientation of the cutter group 4 always maintains the current angle. A fixed shaft II 322 connecting to the bottom surface of the turntable 31 is provided in the middle of the bracket 32. There is an arc surface at the position of the bracket 32 outside the fixed shaft II 322, and a number of meshing teeth I are distributed on the arc surface. A motor I 323 is fixed on the front side of the fixed shaft II 322. The driving end of the motor I 323 meshes with the meshing teeth I. When the motor I 323 is driven, it drives the bracket 32 to rotate, so that the cutter group 4 slides along the chute II 311 to gather or expand. A motor II 324 is fixed on the right side of the fixed shaft II 322.

[0037] A fixed shaft III 424 inserted into the chute II 311 is provided on the lower side of the cutter body 42, and the lower end of the fixed shaft III 424 extends to the lower side of the turntable 31. A through hole II 4241 for the extension end 321 to penetrate is provided at the lower end of the fixed shaft III 424. A limiting piece 4242 clamped in the expanded area of the chute II 311 is provided at the top end of the fixed shaft III 424.

[0038] A number of meshing teeth II are distributed on the outer circumference of the bottom of the base 3. The driving end of the motor II 324 meshes with the meshing teeth II. When the motor II 324 is driven, it drives the turntable 31 to rotate, so that the cutter group 4 cuts the root of the eaves column. A pair of insertion teeth II 33 clamped in the bayonet 11 are provided on the base 3. The lifting of the base 3 is adjusted by adjusting the clamping height of the insertion teeth II 33 in the bayonet 11, and the cutting height of the cutter group 4 for the root of the eaves column is adjusted.

[0039] A method for using and a working mode of an eaves column root cutting device provided by the present invention include the following steps:

[0040] Step 1: In the initial state, unfold the cutting main body 1, place the base 3 directly below the eaves column through the gap between a pair of cutter groups 4, and make the central axis of the eaves column coincide with the central axis of the cutting main body 1. Combine the cutting main body 1, and drive the hydraulic pump body 2 to make a number of oil cylinders 21 press against the outer circumference of the eaves column to support the eaves column to prevent it from descending.

[0041] Step 2: During the process of removing the rotten part on the outer circumference of the column core, hold the middle part of the cutter head 41 and press it vertically downward. The cutter head 41 slides downward along the chute I 411. The outer insertion tooth I 43 presses the clamping block II 52 downward. The clamping block II 52 gradually slides outward along the inclined surface of the insertion tooth I 43, and the clamping part II 521 is clamped to the lower end of the cutter head 41, so that the cutter head 41 and the cutter body 42 are kept upright. After driving the motor II 324, the turntable 31 rotates, and the planer blade 422 cuts and removes the rotten part on the outer circumference of the column core, which is convenient for inlaying the root of the eaves column.

[0042] Step 3: In the process of cutting the bottom surface of the column root, hold the middle part of the cutter head 41 and lift it upward. After the pinion cutter I 43 moves upward, the spring 53 presses the engaging block II 52 to reset. After the cutter head 41 rotates 90° inward first, press the cutter head 41 outward. The pinion cutter I 43 located inside passes through the through hole III 522 and presses the engaging block I 51. The engaging block I 51 gradually slides outward along the inclined surface of the pinion cutter I 43, and the engaging part I 512 engages with the lower end of the cutter head 41, keeping the cutter head 41 perpendicular to the tool body 42. After driving the motor II 324, the turntable 31 rotates, and the cutter head 41 cuts the column core in the horizontal direction, making the lower end of the column root of the eaves column a flat surface, which is convenient for placing it in the stone socket of the column capstone, or for forming a tenon head to facilitate the butt joint of the eaves column.

[0043] The above is only the preferred embodiment of the present invention. It should be noted that for those skilled in the art of this technology, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements are all regarded as within the protection scope of the present invention.
