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 a wooden frame column. Background Art

[0002] The timber frame is the main structural skeleton in ancient Chinese buildings. It is a support system made of wood and is used to bear the weight of the building and maintain the building form. The structural forms of the timber frame of ancient buildings mainly include the beam-lifting timber frame and the beam-through timber frame. Both structural forms of timber frames are supported by beams, rafters, purlins, and other components on the columns to form a support system; at the same time, the position and arrangement of the columns also determine the spatial division of the building. Therefore, the columns are the key nodes in the construction process of the timber frame of ancient buildings and play an important role.

[0003] When installing the column, it is necessary to lift the column so that its tenon is aligned with the mortise on the column base and inserted. Depending on the size of the column, the conventional methods of lifting the column mainly include manual lifting, setting up a pulley block, and using a crane. Among them, for smaller and lighter columns, 4-6 workers are required to cooperate to lift and install the column; if a pulley block is to be set up, it is necessary to build a suitable scaffolding or hanger, and then install the pulley block, rope, winch, etc. on the scaffolding or hanger; and for larger and heavier columns, a crane is required for lifting operations. Therefore, the conventional column lifting method has either high labor costs or high equipment costs, and its assembly is difficult. After the assembly is completed, the column needs to be calibrated, and the installation efficiency is low. Summary of the invention

[0031] To achieve the above object, the present application also provides a method for installing a wooden 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: controlling the lifting assembly to tighten the cable, so that the fixing mechanism drives the top end of the column to lift, and at the same time the end of the column drives the bracket to rotate, until the column is suspended in a vertical state and hovers in the clamping area of ​​the first clamping assembly and the second clamping assembly;

[0034] S3, clamping and lifting the column: start 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 start the lifting assembly to lift the lifting assembly together with the hoisting assembly, the first clamping assembly, the second clamping assembly, the bracket and the column to a certain height;

[0035] S4. Alignment of columns: Use the base to move the wooden frame column installation auxiliary device together with the column to the column base position, and store the bracket under the lifting component through the connection part or rotate it to one side of the lifting component to avoid it, so that the column is located directly above the column base; then put down the supporting feet of the auxiliary support component 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 moves to the vicinity of the hoisting component with the help of the climbing component and unlocks the fixing mechanism, and at the same time releases the squeezing force of the first clamping component and the second clamping component, so that the column is constrained in the horizontal direction, but can move in the vertical direction under the action of external force; then the worker gently taps the top of the column with a wooden mallet or a leather hammer, so that the column is gradually installed into the column base in the vertical direction;

[0037] S6. Release the column: After the column is tightly connected to the column base, the first clamping assembly and the second clamping assembly are controlled to reset, so that the column is freed from the constraint of the auxiliary device for installing the wooden frame column, 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] Loosen 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 move freely in a direction away from the outer fixed section by 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 fixed arm and the second fixed arm so that the two rocker arms are in a horizontal state; at the same time, move the inner fixing rollers of the first fixed arm and the second fixed arm toward their corresponding outer fixing sections, until each inner fixing roller abuts against the inner walls of both sides of the mortise, and each outer fixing section abuts against the side wall of the column;

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

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

[0044] When the column is suspended in the clamping area, the first clamping arm and the second clamping arm slide along the support frame toward the column at the same speed at the same time until the first buffer block and the third buffer block are both 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 starts 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 unlocking 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 wooden frame column installation auxiliary device of the present application, the installation of the wooden frame column can be completed by a single person, reducing labor costs; mechanized assembly is easy to operate and reduces the labor intensity of workers; at the same time, secondary correction after installation is avoided, and the installation efficiency is high.

[0080] In a wooden frame, a mortise is usually processed at the top of a column for installing a beam or connecting a square. The shape of the mortise is usually rectangular, square and dovetail, and its size is determined according to the cross-sectional size of the beam or square and the connection requirements; the bottom of the column needs to be processed with a square or round tenon that matches the column base. Accordingly, a sleeve-shaped tenon hole is opened on the column base to meet the installation requirements. In order to solve the problem of difficult assembly and low installation efficiency of existing wooden frame columns, the present application provides a wooden frame column installation auxiliary device, and the specific embodiments 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 component 3, a first clamping component 4, a second clamping component 5, a hoisting component 6 and a bracket 7. The hoisting component 6, the first clamping component 4, the second clamping component 5 and the bracket 7 are arranged in sequence from top to bottom in the vertical direction Y.

[0082] In this embodiment, the base column 1 is extended along the vertical direction Y and is the main support part 71 of the auxiliary device for installing the wooden frame column 10. The base 2 is fixedly connected to the bottom of the base column 1 and has the ability to move. For example, a caster structure such as a fixed wheel, a universal wheel, or a Mecanum wheel can be installed on the base 2. The lifting assembly 3 can be lifted relative to the base column 1 in the vertical direction Y. Specifically, the lifting assembly 3 can be assembled and connected with the base column 1 by means of electric slide rails, electric slide rods, chain lifting, etc.

[0083] In this embodiment, the first clamping assembly 4 and the second clamping assembly 5 are two components with the same structure. The first clamping assembly 4 and the second clamping assembly 5 are both installed on the lifting assembly 3, and the first clamping assembly 4 and the second clamping assembly 5 can adjust their positions in the vertical direction Y relative to the lifting assembly 3. For example, an electric slide rail can be arranged on the lifting assembly 3 along the vertical direction Y or a plurality of installation positions can be set along the vertical direction Y, thereby providing a suitable installation position for the first clamping assembly 4 and the second clamping assembly 5 according to the specific size of the column 10. Among them, the first clamping assembly 4 and the second clamping assembly 5 have a clamping mechanism 41 arranged 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 column 10 is clamped at different heights by the two clamping mechanisms 41, and the base column 1 is used as the reference for verticality, so that the verticality of the column 10 will not have a large deviation during the process of installing the column 10 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 hoisting 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. Among them, the hoisting assembly 6 has a fixing mechanism 61 and a cable 62, and the fixing mechanism 61 is lowered and retracted by the cable 62. 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 hoisting 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 lifting the column 10, first place the end of the column 10 with the tenon on the bracket 7, and then use the lifting component 6 to lower 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 and 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, and the lifting operation is completed.

[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 and lifting, reducing the labor intensity of the workers, avoiding the construction of a series of structural frames and secondary correction after installation, and the installation efficiency is high.

[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 setting a number of installation positions on the column 10, and setting an assembly structure corresponding to the installation position on the support frame 411. By allowing the assembly structure of the support frame 411 to be fixedly connected to the installation positions at different positions, the relative position of each support frame 411 in the vertical direction Y can be flexibly adjusted, so that the first clamping assembly and the second clamping assembly can 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 hoisting 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 both in contact with the column 10. Among them, when 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 will automatically adjust the position 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 are basically overlapped, so as to avoid the situation where the column 10 is excessively tilted and affects 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 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 stopper section 4132 is activated to rotate toward the clamping area, so that the fourth buffer block 41321 abuts against the column 10; if the column 10 does not contact the second buffer block 4111, the column 10 will also be pushed by the stopper section 4132 through the fourth buffer block 41321 to abut against the second buffer block 4111. As a result, the column 10 will be abutted and clamped by the first buffer block 4121, the second buffer block 4111, the third buffer block 41311 and the fourth buffer block 41321 from four different directions, so as to realize the constraint and fixation of the column 10 in the horizontal direction X.

[0093] Among them, the first buffer block 4121, the second buffer block 4111, the third buffer block 41311 and the fourth buffer block 41321 are buffer components of the same material, which can be rubber buffer blocks, polyurethane buffer blocks, high-density sponges, etc. In particular, the contact surfaces of the first buffer block 4121, the second buffer block 4111 and the third buffer block 41311 are parallel to the assembly support surface; the projection of the fourth buffer block 41321 in the vertical direction Y is a right-angled trapezoid with the side away from the connecting section 4131 higher than the side adjacent to the connecting section 4131, so that the fourth buffer block 41321 can be more easily contacted with the column 10 during the clamping operation, thereby increasing the action stroke of the stop section 4132 and adapting to columns 10 of more 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, and further improving the restraining and fixing effect of the clamping mechanism 41 on the column 10.

[0095] In this embodiment, the action element can be a diaphragm-type clamping cylinder, a short-stroke electric push rod, a mechanical screw, etc. Among them, the diaphragm-type clamping cylinder is a compact piston rodless cylinder with a diaphragm, and its output end, that is, the moving part, is a diaphragm made of materials such as fabric rubber, steel sheet or phosphor bronze sheet. Its working principle is that the compressed air enters the rodless cavity from the air port and pushes the diaphragm, and the tray compresses the spring to move the piston rod downward; when the compressed air is discharged from the rodless cavity from the air port, the spring releases energy to push the diaphragm, and the tray and the piston rod 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 connection plate 611 is fixedly connected to the cable 62; the first fixed arm 612 and the second fixed arm 613 are fixed structures symmetrically arranged and movably connected to both sides of the connection plate 611. Specifically, the first fixed arm 612 and the second fixed arm 613 can be connected to the connection plate 611 through a flexible connector such as a braided rope, a braided belt, an elastic strip, etc.

[0098] In this embodiment, the first fixed arm 612 / the 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, and the other end of the rocker arm 6122 is slidably connected to one end of the outer fixed section 6121, and the rocker arm 6122 can rotate 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] Among them, 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 part 72 is hinged to the bottom of the lifting assembly 3, and the other end of the connection part 72 is hinged to the support part 71. The connection part 72 and the lifting assembly 3 can be hinged through 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 and avoided to the sides of the lifting assembly 3.

[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, first align the tenon processed on the column 10 and install it into the positioning groove 711; then, when the column 10 is lifted from the ground by the lifting assembly 6, the column 10 will drive the bracket 7 to rotate accordingly through the contact between the tenon and the positioning groove 711, so that the bracket 7 can provide positioning assistance for the column 10 and ensure that the column 10 can be supported and supported when it is lifted to any angle.

[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 Fig.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 has a foot 81 for increasing the ground contact area of ​​the base 2 when installing the column 10, and the foot 81 is fixedly connected to the base 2; the climbing assembly 9 can be a ladder installed on the base column 1 or a lifting work platform attached to the base column 1, so that when installing the column 10, the worker can use a mallet or a leather hammer to hit the column 10 from above the column 10, so that the column 10 is installed into the column base 11 along the vertical direction Y. For example, in order to adapt to different size and weight requirements of the column 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 a 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: placing the end of the column 10 with the tenon processed on the bracket 7; using the lifting assembly 6 to lower the fixing mechanism 61, and fixing the top of the column 10 with the mortise processed by the fixing mechanism 61;

[0108] S2, lifting the column 10: controlling the lifting assembly 6 to tighten the cable 62, so that the fixing mechanism 61 drives the top end of the column 10 to lift, and at the same time the end of the column 10 drives the bracket 7 to rotate, until the column 10 is suspended in a vertical state and hovers in the clamping area of ​​the first clamping assembly 4 and the second clamping assembly 5;

[0109] S3, clamping and lifting the column 10: start the first clamping assembly 4 and the second clamping assembly 5, so that the clamping mechanism 41 of the first clamping assembly 4 and the second clamping assembly 5 clamps the column 10 and applies a squeezing force in the horizontal direction X to fix it; then start the lifting assembly 3, and lift the lifting assembly 3 together with the hoisting assembly 6, the first clamping assembly 4, the second clamping assembly 5, the bracket 7 and the column 10 to a certain height;

[0110] S4, alignment of the column 10: using 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 component 3 through the connecting portion 72 or rotated to one side of the lifting component 3 to avoid it, so that the column 10 is located directly above the column base 11; then the support leg 81 of the auxiliary support component 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 staff moves to the vicinity of the hoisting component 6 with the help of the climbing component 9 and unlocks the fixing mechanism 61, and at the same time releases the squeezing force of the first clamping component 4 and the second clamping component 5, so that the column 10 is constrained in the horizontal direction X, but can move in the vertical direction Y under the action of external force; then the staff 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, releasing the column 10: after the column 10 is tightly connected to the column base 11, the first clamping assembly 4 and the second clamping assembly 5 are controlled 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 by using the base 2 to complete the installation of the column 10.

[0113] In this embodiment, the present application uses 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 deviating 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 for lifting, and then the column 10 is lifted and moved; when the column 10 moves to the corresponding column base 11 position, The constraint of the vertical direction Y of the column 10 can be released by unlocking the fixing mechanism 61 of the lifting assembly 6 and retracting the bracket 7, 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 less manpower, and has the advantages of high installation accuracy and high operating efficiency, which can greatly assist the repair of ancient buildings with wooden frame structures or the construction of antique buildings.

[0114] In one embodiment, based on the above-mentioned embodiment, the process of fixing the top 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 move freely in the direction away from the outer fixed section 6121 by using the rocker arm 6122;

[0116] The fixing mechanism 61 is installed from one side of the column 10 to 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 fixed arm 612 and the second fixed arm 613 so that the two rocker arms 6122 are in a horizontal state; at the same time, move the inner fixing rollers 6123 of the first fixed arm 612 and the second fixed arm 613 toward their corresponding outer fixing sections 6121, until each inner fixing roller 6123 abuts against the inner walls of both sides of the mortise, and each outer fixing section 6121 abuts against the side wall of the column 10;

[0118] The rocker arm 6122 is fastened by 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 by virtue of the flexibility of the rocker arm 6122, and the structure of the single-sided rocker arm 6122 enables 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 respectively abut against the inner walls of both sides of the mortise, and each outer fixing section 6121 respectively 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. After the rocker arm 6122 is locked, the distance between the outer fixing section 6121 and the inner fixing roller 6123 is fixed. 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-mentioned 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 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 are both in contact with the column 10;

[0122] When 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 starts to rotate toward the column 10 around the hinge point; 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 by the stop section 4132 to make it contact with the column 10, 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 stopper section 4132 to different angles, the clamping mechanism 41 can clamp the 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 substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
