Description

Technical Field

[0001] The present application belongs to the technical field of auxiliary devices for ancient building construction, and specifically relates to an auxiliary device and method for installing wooden frame columns. Background Art

[0002] The timber frame is the primary structural framework of ancient Chinese architecture. It is a support system constructed from wood, used to bear the weight of the building and maintain its form. The main structural forms of ancient timber frames include the raised-beam timber frame and the through-beam timber frame. Both types of timber frames rely on columns to support beams, rafters, purlins, and other components. The position and arrangement of columns also determine the spatial divisions of the building. Therefore, columns are key nodes in the construction process of ancient timber frames and play an important role.

[0003] When installing a column, it needs to be hoisted so that its tenon is aligned with the mortise on the column base and inserted. Depending on the size of the column, conventional methods of hoisting the column mainly include manual lifting, setting up a pulley block, and using a crane. Among them, even for smaller and lighter columns, 4-6 workers are required to cooperate in hoisting and installing the column; if a pulley block is required, a suitable scaffolding or hanger must be built, and then the pulley block, rope, winch, etc. must be installed on the scaffolding or hanger; and for larger and heavier columns, a crane is required for the lifting operation. Therefore, conventional column hoisting methods either have high labor costs or high equipment costs, are difficult to assemble, and the column needs to be corrected after assembly, which makes the installation operation inefficient.

[0030] The climbing component can be a ladder installed on the base column or a lifting work platform attached to the base column.

[0031] To achieve the above objectives, the present application also provides a method for installing a timber frame column, the method comprising:

[0032] S1. Fix the column: Place the end of the column with the tenon on the bracket; Use the lifting assembly to lower the fixing mechanism, and use the fixing mechanism to fix the top of the column with the mortise;

[0033] S2. Lifting the column: Control the lifting assembly to tighten the cable, causing the fixing mechanism to drive the top end of the column to lift, while the bottom end of the column drives the bracket to rotate until the column is suspended in a vertical position and hovers within the clamping area of ​​the first clamping assembly and the second clamping assembly;

[0034] S3. Clamping and lifting the column: activating the first clamping assembly and the second clamping assembly so that the clamping mechanisms of the first clamping assembly and the second clamping assembly clamp the column and apply a horizontal squeezing force to fix it; then activating the lifting assembly to lift the lifting assembly, the hoisting assembly, the first clamping assembly, the second clamping assembly, the bracket, and the column to a certain height;

[0035] S4. Column alignment: Use the base to move the timber frame column installation auxiliary device together with the column to the column base position. The bracket is stored under the lifting assembly through the connection part or rotated to the side of the lifting assembly to avoid it, so that the column is directly above the column base. Then, lower the support leg of the auxiliary support assembly to ensure the verticality of the base column and the column, and align the tenon of the column with the mortise of the column base.

[0036] S5. Installing the column: The worker uses the climbing assembly to move to the vicinity of the hoisting assembly and unlocks the fixing mechanism. Simultaneously, the squeezing force of the first and second clamping assemblies is released, so that the column is constrained in the horizontal direction but can move vertically under the action of external force. The worker then gently taps the top of the column with a wooden mallet or a leather hammer, gradually inserting the column vertically into the column base.

[0037] S6. Release the column: After the column is tightly connected to the column base, control the first clamping assembly and the second clamping assembly to reset, so that the column is freed from the constraints of the wooden frame column installation auxiliary device, and the device can be removed using the base to complete the installation of the column.

[0038] In one solution, the process of fixing the top end of the column with the mortise by the fixing mechanism is as follows:

[0039] Loosening the locking elements of the first fixed arm and the second fixed arm, so that the inner fixed roller is in a state where it can freely move in a direction away from the outer fixed section using the rocker arm;

[0040] Install the fixing mechanism from one side of the column to the column, so that the inner fixing rollers of the first fixing arm and the second fixing arm are both embedded in the mortise of the column, and the outer fixing sections of the first fixing arm and the second fixing arm are respectively located on both sides of the column;

[0041] Adjust the rocker arms of the first and second fixed arms so that they are horizontal. Simultaneously, move the inner fixing rollers of the first and second fixed arms toward their corresponding outer fixing sections until each inner fixing roller abuts against the inner walls of the mortise and each outer fixing section abuts against the side walls of the column.

[0042] The rocker arm is fastened by the locking element to complete the fixation of the fixing mechanism to the column.

[0043] In one solution, the clamping mechanism clamps the column and applies a horizontal extrusion force to fix it as follows:

[0044] When the column is suspended in the clamping area, the first clamping arm and the second clamping arm slide simultaneously at the same speed along the support frame toward the column until the first buffer block and the third buffer block are in contact with the column;

[0045] When the first clamping arm and the second clamping arm stop sliding, the stop section of the second clamping arm is activated, and the stop section begins to rotate toward the column around the hinge point; after the stop section rotates until the fourth buffer block abuts against the column, it continues to rotate and pushes the column to abut against the second buffer block;

[0046] When the first buffer block, the second buffer block, the third buffer block and the fourth buffer block are all in contact with the column, the action element is activated, and the action element drives the first buffer block to move toward the clamping area, so that the first buffer block squeezes the column, increasing the sliding friction between the column and the first buffer block, the second buffer block, the third buffer block and the fourth buffer block.

[0047] Beneficial effects of this application:

[0048] The present application utilizes a hoisting assembly and a bracket to lift the column, and clamps and fixes the column at different heights through a first clamping assembly and a second clamping assembly. After the column is moved to the corresponding column base position, the vertical constraint of the column can be released by disengaging the fixing mechanism of the hoisting assembly and retracting the bracket, while the horizontal direction of the column is still constrained by the first clamping assembly and the second clamping assembly, thereby ensuring the verticality requirement of the column installation and avoiding the need for repeated correction after the column is installed. With the timber frame column installation auxiliary device of the present application, the installation of the timber frame column can be completed by a single person, reducing labor costs; mechanized assembly is convenient to operate, reducing the labor intensity of workers; and secondary correction after installation is avoided, resulting in high installation efficiency.

[0080] In a timber frame, the top of a column typically requires a mortise for mounting a beam or connecting a plank. Mortises typically come in rectangular, square, or dovetail shapes, with their dimensions determined by the cross-sectional dimensions of the beam or plank and the connection requirements. The bottom of the column requires a square or round tenon that matches the column base. Accordingly, the column base is provided with a sleeve-shaped mortise hole to meet installation requirements. To address the difficulties and inefficiencies of conventional timber frame column assembly, this application provides a timber frame column installation assistance device, the specific embodiments of which are as follows:

[0081] In one embodiment, see Figures 1 to 4 The auxiliary device for installing the wooden frame column 10 includes a base column 1, a base 2, a lifting assembly 3, a first clamping assembly 4, a second clamping assembly 5, a hoisting assembly 6, and a bracket 7. Among them, the hoisting assembly 6, the first clamping assembly 4, the second clamping assembly 5, and the bracket 7 are arranged in order from top to bottom in the vertical direction Y.

[0082] In this embodiment, the base column 1 extends in the vertical direction Y and serves as the primary support 71 for the auxiliary device installed on the timber frame column 10. The base 2 is fixedly connected to the bottom of the base column 1 and is capable of movement. For example, casters such as fixed wheels, universal wheels, or Mecanum wheels can be mounted on the base 2. The lifting assembly 3 can be raised relative to the base column 1 in the vertical direction Y. Specifically, the lifting assembly 3 can be assembled and connected to the base column 1 using methods such as electric slide rails, electric slide rods, and chain hoisting.

[0083] In this embodiment, the first clamping assembly 4 and the second clamping assembly 5 are two identical components. Both the first clamping assembly 4 and the second clamping assembly 5 are mounted on the lifting assembly 3, and both are capable of adjusting their positions relative to the lifting assembly 3 in the vertical direction Y. For example, by arranging an electric slide rail or providing a plurality of mounting positions along the vertical direction Y on the lifting assembly 3, suitable mounting positions for the first clamping assembly 4 and the second clamping assembly 5 can be provided based on the specific dimensions of the column 10. The first clamping assembly 4 and the second clamping assembly 5 have a clamping mechanism 41 disposed along the horizontal direction X, and the projections of the first clamping assembly 4 and the second clamping assembly 5 in the vertical direction Y overlap. The two clamping mechanisms 41 clamp the column 10 at different heights, and the base column 1 is used as a reference for verticality. This ensures that the verticality of the column 10 will not deviate significantly during its installation into the column base 11, thereby avoiding the need for verticality correction after the column 10 is installed.

[0084] In this embodiment, the hoisting assembly 6 and the bracket 7 are the main functional components for lifting the column 10. The hoisting assembly 6 is fixedly mounted on the top of the lifting assembly 3 in the vertical direction Y, and the bracket 7 is fixedly mounted on the bottom of the lifting assembly 3 in the vertical direction Y. The hoisting assembly 6 has a fixing mechanism 61 and a cable 62. The cable 62 is used to achieve the lowering and retracting of the fixing mechanism 61. Specifically, the cable 62 is equipped with a winch, capstan, or hoist. The bracket 7 is used to support and support the column 10 during the process of lifting and moving the column 10. The bracket 7 can be evaded and stored or evaded and rotated relative to the lifting assembly 3 to make way for the installation of the column 10.

[0085] When the column 10 is lifted, the end of the column 10 with the tenon is first placed on the bracket 7, and then the lifting component 6 lowers the fixing mechanism 61 from the top of the lifting component 3 through the cable 62. The worker installs and fixes the released fixing mechanism 61 to the end of the column 10 with the mortise, and then retracts the cable 62. Under the traction of the cable 62, the column 10 will use the bracket 7 as a fulcrum. As the fixing mechanism 61 gradually leaves the ground and approaches the lifting component 3, until the column 10 is suspended in a vertical state, it can be clamped and fixed by the first clamping component 4 and the second clamping component 5, completing the lifting operation.

[0086] Therefore, by using the auxiliary device for installing the wooden frame column 10 of the present application, a single person can complete the installation of the wooden frame column 10, reducing labor costs; at the same time, the integrated mechanical assembly and lifting are more convenient to operate than the traditional manual binding, fixing and lifting, reducing the labor intensity of workers, avoiding the construction of a series of structural frames and secondary correction after installation, and having high installation efficiency.

[0087] In one embodiment, see Figure 1 、 Figure 2 、 Figure 4 and Figure 6 The clamping mechanism 41 includes a support frame 411 , a first clamping arm 412 and a second clamping arm 413 .

[0088] In this embodiment, the support frame 411 is slidably connected or detachably fixedly connected to the lifting assembly 3, and both ends of the support frame 411 extend along the horizontal direction X. Exemplarily, the slidable connection between the support frame 411 and the lifting assembly 3 can be achieved by arranging corresponding electric slide rails or slide rods on the lifting assembly 3; the detachable fixed connection can be achieved by providing a plurality of mounting positions on the column 10, and providing an assembly structure corresponding to the mounting positions on the support frame 411. By fixedly connecting the assembly structure of the support frame 411 to the mounting positions at different positions, the relative position of each support frame 411 in the vertical direction Y can be flexibly adjusted, thereby enabling the first clamping assembly and the second clamping assembly to meet the clamping requirements of columns 10 of different sizes.

[0089] In this embodiment, the first clamping arm 412 and the second clamping arm 413 are both slidably connected to the support frame 411; the first clamping arm 412, the support frame 411, and the second clamping arm 413 constrain to form a clamping area for fixing the column 10. When the column 10 is lifted to the clamping area by the lifting assembly 6, the first clamping arm 412 and the second clamping arm 413 of each clamping mechanism 41 slide toward the clamping area at the same speed until the first clamping arm 412 and the second clamping arm 413 are in contact with the column 10. Specifically, after the clamping mechanism 41 of the first clamping assembly and the clamping mechanism 41 of the second clamping assembly simultaneously complete the clamping action on the column 10, the clamping mechanism 41 of the first clamping assembly and the clamping mechanism 41 of the second clamping assembly automatically adjust their positions in the horizontal direction X to ensure that the projections of the first clamping assembly and the second clamping assembly in the vertical direction Y substantially overlap, thereby preventing the column 10 from being excessively tilted and affecting the verticality requirement during installation.

[0090] In one embodiment, based on the above embodiments, and referring to Figures 6 to 8 A first buffer block 4121 is provided on a side of the first clamping arm 412 facing the second clamping arm 413 ; a second buffer block 4111 is provided on a middle portion of the support frame 411 facing away from the lifting assembly 3 .

[0091] The second clamping arm 413 includes a connecting section 4131 and a stop section 4132, one end of the connecting section 4131 is slidably connected to the support frame 411, and the other end of the connecting section 4131 is hinged to the stop section 4132; the stop section 4132 can rotate toward the clamping area around the hinge point; a third buffer block 41311 is provided on the side of the connecting section 4131 facing the first clamping arm 412; a fourth buffer block 41321 is provided on the side of the stop section 4132 adjacent to the clamping area; all parts of the clamping mechanism 41 are electrically connected.

[0092] In this embodiment, after the column 10 is lifted to the clamping area by the hoisting assembly 6, the column 10 either first contacts the second buffer block 4111 or does not contact any component of the clamping mechanism 41. After the first clamping arm 412 and the second clamping arm 413 slide toward the clamping area at the same speed, the column 10 will abut against the first buffer block 4121 and the third buffer block 41311. Then, the stop section 4132 is activated to rotate toward the clamping area, causing the fourth buffer block 41321 to abut against the column 10. If the column 10 does not contact the second buffer block 4111, the stop section 4132 will push the column 10 through the fourth buffer block 41321 until it abuts against the second buffer block 4111. As a result, the column 10 will be abutted and clamped from four different directions by the first buffer block 4121, the second buffer block 4111, the third buffer block 41311, and the fourth buffer block 41321, thereby achieving constraint and fixation of the column 10 in the horizontal direction X.

[0093] The first, second, third, and fourth buffer blocks 4121, 4111, 41311, and 41321 are made of the same material, specifically rubber, polyurethane, or high-density sponge. Specifically, the contact surfaces of the first, second, and third buffer blocks 4121, 4111, and 41311 are parallel to the assembly support surface. The projection of the fourth buffer block 41321 in the vertical direction Y forms a right-angled trapezoid, with the side facing away from the connecting section 4131 higher than the side adjacent to the connecting section 4131. This allows the fourth buffer block 41321 to more easily contact the column 10 during clamping operations, increasing the travel of the stop section 4132 and accommodating a wider range of column 10 sizes.

[0094] In one embodiment, based on the aforementioned embodiment, the first clamping arm 412 is further provided with an action element for adjusting the first buffer block 4121; after the column 10 is constrained in the clamping area, the action element can drive the first buffer block 4121 to move toward the clamping area, so that the first buffer block 4121 squeezes the column 10, thereby increasing the sliding friction between the column 10 and the first buffer block 4121, the second buffer block 4111, the third buffer block 41311 and the fourth buffer block 41321, further improving the restraining and fixing effect of the clamping mechanism 41 on the column 10.

[0095] In this embodiment, the actuating element may be a diaphragm-type clamping cylinder, a short-stroke electric push rod, a mechanical lead screw, etc. The diaphragm-type clamping cylinder is a compact rodless cylinder with a diaphragm. Its output end, i.e., the moving part, is a diaphragm made of materials such as fabric-reinforced rubber, steel sheet, or phosphor bronze sheet. Its operating principle is that compressed air enters the rodless chamber through the air port, pushing the diaphragm. The tray compresses the spring, causing the piston rod to move downward. When the compressed air is discharged from the rodless chamber through the air port, the spring releases energy to push the diaphragm, causing the tray and piston rod to move upward.

[0096] In one embodiment, see Figures 1 to 4 and Figures 9 to 11 The fixing mechanism 61 includes a connecting plate 611 , a first fixing arm 612 and a second fixing arm 613 .

[0097] In this embodiment, the connecting plate 611 is fixedly connected to the cable 62; the first and second fixing arms 612, 613 are symmetrically arranged and movably connected to the connecting plate 611. Specifically, the first and second fixing arms 612, 613 can be connected to the connecting plate 611 via a flexible connector such as a braided rope, a braided belt, or an elastic strip.

[0098] In this embodiment, the first fixed arm 612 / second fixed arm 613 comprises an outer fixed section 6121, a rocker arm 6122, and an inner fixed roller 6123. One end of the rocker arm 6122 is fixedly connected to the central axis of the inner fixed roller 6123, while the other end of the rocker arm 6122 is slidably connected to one end of the outer fixed section 6121. The rocker arm 6122 is rotatable relative to the outer fixed section 6121. The outer fixed section 6121 and the inner fixed roller 6123 are located on the same side of the rocker arm 6122. The outer fixed section 6121 has a locking element for the rocker arm 6122, which can be a brake, a latch structure, or a wedge stop mechanism.

[0099] The contact surface between the outer fixing section 6121 and the column 10 and the outer side of the inner fixing roller 6123 are both provided with an elastic buffer layer to prevent the surface of the column 10 from being damaged due to excessive extrusion stress between the outer fixing section 6121 and the inner fixing roller 6123.

[0100] In one embodiment, see Figure 1 、 Figure 2 and Figure 5 The bracket 7 includes a supporting portion 71 and a connecting portion 72 .

[0101] In this embodiment, one end of the connection portion 72 is hinged to the bottom of the lifting assembly 3, and the other end of the connection portion 72 is hinged to the support portion 71. The connection portion 72 and the lifting assembly 3 can be hinged via a hinge axis in the horizontal direction X or the vertical direction Y. That is, when the column 10 needs to be avoided during installation, the bracket 7 can be stored and avoided below the lifting assembly 3 or rotated to the sides of the lifting assembly 3 to avoid it.

[0102] In this embodiment, the support portion 71 is configured with a positioning groove 711 for accommodating the tenon at the end of the column 10. When lifting the column 10, the tenon machined on the column 10 is first aligned and inserted into the positioning groove 711. Then, as the column 10 is lifted from the ground by the lifting assembly 6, the contact between the tenon and the positioning groove 711 drives the bracket 7 to rotate accordingly. In this way, the bracket 7 not only provides positioning assistance for the column 10, but also ensures that the column 10 is supported and supported at any angle when lifted.

[0103] In particular, the inner wall of the positioning groove 711 can be provided with an elastic fixing structure having a compression spring, a gas spring, etc., which can improve the fixing ability of the positioning groove 711 to the tenon and can also serve as an automatic adjustment component to enable the bracket 7 to adapt to columns 10 of more sizes.

[0104] In one embodiment, see Figure 4 and Figure 12 The auxiliary device for installing the wooden frame column 10 also includes an auxiliary support component 8 and a climbing component 9.

[0105] In this embodiment, the auxiliary support assembly 8 includes legs 81 for increasing the ground contact area of ​​the base 2 when installing the column 10. The legs 81 are fixedly connected to the base 2. The climbing assembly 9 can be a ladder mounted on the base column 1 or a lifting work platform attached to the base column 1. When installing the column 10, a worker can strike the column 10 from above with a mallet or a leather hammer, so that the column 10 is installed into the column base 11 along the vertical direction Y. For example, to accommodate different sizes and weights of the columns 10, a counterweight can be added to the base 2 to maintain the stability of the device.

[0106] To achieve the above purpose, the present application also provides a method for installing the timber frame column 10 based on the auxiliary device for installing the timber frame column 10 in the above embodiment, please refer to Figures 2 to 5 , the method comprises at least the following steps:

[0107] S1. Fixing the column 10: Place the end of the column 10 with the tenon on the bracket 7; Use the lifting assembly 6 to lower the fixing mechanism 61, and use the fixing mechanism 61 to fix the top of the column 10 with the mortise;

[0108] S2. Lifting the column 10: Control the hoisting assembly 6 to tighten the cable 62, causing the fixing mechanism 61 to drive the top end of the column 10 to lift. Simultaneously, the bottom end of the column 10 drives the bracket 7 to rotate until the column 10 is suspended in a vertical position and hovers within the clamping area of ​​the first clamping assembly 4 and the second clamping assembly 5.

[0109] S3. Clamp and lift column 10: Activate first clamp assembly 4 and second clamp assembly 5 so that clamping mechanisms 41 of first clamp assembly 4 and second clamp assembly 5 clamp column 10 and apply a squeezing force in a horizontal direction X to secure it. Then activate lifting assembly 3 to lift lifting assembly 3, hoisting assembly 6, first clamp assembly 4, second clamp assembly 5, bracket 7, and column 10 to a certain height.

[0110] S4. Alignment of the column 10: Use the base 2 to move the auxiliary device for installing the wooden frame column 10 together with the column 10 to the position of the column base 11. The bracket 7 is stored under the lifting assembly 3 through the connection portion 72 or rotated to the side of the lifting assembly 3 to avoid it, so that the column 10 is directly above the column base 11; then, the support leg 81 of the auxiliary support assembly 8 is lowered to ensure the verticality of the base column 1 and the column 10, and at the same time, the tenon of the column 10 is aligned with the mortise of the column base 11;

[0111] S5. Installing the column 10: The worker uses the climbing assembly 9 to move to the vicinity of the hoisting assembly 6 and disengages the fixing mechanism 61. Simultaneously, the squeezing force of the first clamping assembly 4 and the second clamping assembly 5 is released, so that the column 10 is constrained in the horizontal direction X but can move in the vertical direction Y under the action of an external force. The worker then gently taps the top of the column 10 with a wooden mallet or a leather hammer, so that the column 10 is gradually installed into the column base 11 along the vertical direction Y.

[0112] S6. Release the column 10: After the column 10 is tightly connected to the column base 11, control the first clamping assembly 4 and the second clamping assembly 5 to reset, so that the column 10 is freed from the constraint of the auxiliary device for installing the wooden frame column 10, and the device can be removed using the base 2 to complete the installation of the column 10.

[0113] In this embodiment, the present application utilizes the hoisting assembly 6 and the mortise to fix the column 10, and combines the bracket 7 to suspend the column 10 from the ground in a vertical state; then the first clamping assembly 4 and the second clamping assembly 5 are used to clamp the column 10 at different heights to prevent the column 10 from deflecting in the horizontal direction X; at the same time, the lifting assembly 3 is used to carry the hoisting assembly 6, the first clamping assembly 4, the second clamping assembly 5 and the bracket 7 to lift, thereby lifting and moving the column 10; when the column 10 moves to the position corresponding to the column base 11, By releasing the fixing mechanism 61 of the hoisting assembly 6 and retracting the bracket 7, the constraint of the vertical direction Y of the column 10 can be released, while the horizontal direction X of the column 10 is still constrained by the first clamping assembly 4 and the second clamping assembly 5. On this basis, the staff can knock the column 10 from the top of the column 10 to align the tenon of the column 10 with the mortise of the column base 11 for installation. The overall installation process is convenient to operate, requires little manpower, and has the advantages of high installation accuracy and high operating efficiency, which can greatly assist in the repair of ancient buildings with wooden frame structures or the construction of antique buildings.

[0114] In one embodiment, based on the above embodiment, the process of fixing the top end of the column 10 with the mortise by using the fixing mechanism 61 is as follows:

[0115] Loosen the locking elements of the first fixed arm 612 and the second fixed arm 613 so that the inner fixed roller 6123 can freely move away from the outer fixed section 6121 using the rocker arm 6122;

[0116] Install the fixing mechanism 61 from one side of the column 10 toward the column 10, so that the inner fixing rollers 6123 of the first fixing arm 612 and the second fixing arm 613 are both embedded in the mortise of the column 10, and the outer fixing sections 6121 of the first fixing arm 612 and the second fixing arm 613 are respectively located on both sides of the column 10;

[0117] Adjust the rocker arms 6122 of the first and second fixed arms 612, 613 so that they are horizontal. Simultaneously, move the inner fixing rollers 6123 of the first and second fixed arms 612, 613 toward their corresponding outer fixing sections 6121 until each inner fixing roller 6123 abuts against the inner walls of the mortise and each outer fixing section 6121 abuts against the side walls of the column 10.

[0118] The rocker arm 6122 is fastened using a locking element to complete the fixation of the fixing mechanism 61 to the column 10 .

[0119] In this embodiment, the first fixed arm 612 and the second fixed arm 613 can conveniently insert the inner fixed roller 6123 into the mortise on the column 10 through the flexibility of the rocker arm 6122, and the structure of the single-sided rocker arm 6122 allows the inner fixed roller 6123 to be installed into the mortise from either side of the column 10, which can adapt to the processing of mortises at different positions on the column 10 and has good applicability. By having each inner fixing roller 6123 abut against the inner walls of both sides of the mortise, and each outer fixing section 6121 abut against the side walls of the column 10, when the column 10 is lifted off the ground, under the action of the column 10's own gravity, the inner wall of the mortise will drive the cylinder of the inner fixing roller 6123 to rotate to a certain extent. Since the distance between the outer fixing section 6121 and the inner fixing roller 6123 is fixed after the rocker arm 6122 is locked, if the inner fixing roller 6123 is offset and rolled, the extrusion stress between the first fixing arm 612 / the second fixing arm 613 and the column 10 will increase, that is, the fixation will be more stable and will not loosen, thereby ensuring the stability of the lifting operation of the column 10.

[0120] In one embodiment, based on the above embodiment, the process of the clamping mechanism 41 clamping the column 10 and applying a squeezing force in the horizontal direction X to fix it is as follows:

[0121] When the column 10 is suspended in the clamping area, the first clamping arm 412 and the second clamping arm 413 simultaneously slide along the support frame 411 toward the column 10 at the same speed until the first buffer block 4121 and the third buffer block 41311 both abut against the column 10;

[0122] After the first clamping arm 412 and the second clamping arm 413 stop sliding, the stop section 4132 of the second clamping arm 413 is activated, and the stop section 4132 begins to rotate about the hinge point toward the column 10. After the stop section 4132 rotates until the fourth buffer block 41321 abuts against the column 10, it continues to rotate and pushes the column 10 to abut against the second buffer block 4111.

[0123] When the first buffer block 4121, the second buffer block 4111, the third buffer block 41311 and the fourth buffer block 41321 are all in contact with the column 10, the action element is activated, and the action element drives the first buffer block 4121 to move toward the clamping area, so that the first buffer block 4121 squeezes the column 10, increasing the sliding friction between the column 10 and the first buffer block 4121, the second buffer block 4111, the third buffer block 41311 and the fourth buffer block 41321.

[0124] In this embodiment, after the first buffer block 4121, the second buffer block 4111 and the third buffer block 41311 are all in contact with the column 10, the column 10 may still move to the side away from the second buffer block 4111 in the horizontal direction X. After the first clamping arm 412 and the second clamping arm 413 stop sliding, the fourth buffer block 41321 is rotated to abut against the column 10 through the stop section 4132, forming four constraint points of the column 10, thereby realizing the limited fixation of the column 10 in the horizontal direction X; on this basis, the first buffer block 4121 is pushed by the action element to increase the sliding friction between the column 10 and the first buffer block 4121, the second buffer block 4111, the third buffer block 41311 and the fourth buffer block 41321, to ensure that when the column 10 is installed, even if the bracket 7 is retracted and the fixing mechanism 61 is released, the column 10 will not loosen from the first clamping assembly and the second clamping assembly. Furthermore, by rotating the stop section 4132 to different angles, the clamping mechanism 41 can clamp columns 10 of different sizes.

[0125] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
