Description

Technical Field

[0001] This invention relates to the field of panel installation, and specifically to an auxiliary device and construction method for ALC panel installation. Background Technology

[0002] ALC (Autoclaved Lightweight Concrete) panels (hereinafter referred to as panels) are panel-shaped building components made of autoclaved lightweight aerated concrete. They are widely used in buildings such as factories, libraries, and shopping malls, and have advantages such as being lightweight and high-strength, having good thermal and sound insulation properties, long-lasting fire resistance, simple construction, and being environmentally friendly. During the installation of ALC panels, due to their large size and weight, mechanical assistance is usually required to lift one end of the panel to make it upright for installation.

[0003] However, in some locations with a curb, manual pry bar is still needed to move the strips onto the curb. On the one hand, the strips are heavy and it is very troublesome to knock them. On the other hand, the surface of the strips and the curb is easily damaged during the prying process, reducing the appearance quality. Therefore, a convenient and practical auxiliary device is needed that can directly install the strips onto the curb. Summary of the Invention

[0004] The present invention aims to provide an auxiliary device for installing ALC strips, which can directly install the strips on the countersunk edge.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary device and construction method for installing ALC strip panels, comprising a movable support and a rotating support. The movable support is equipped with a winch at its lower part and a fixed pulley at its upper part. A steel cable is wound on the winch, and the upper end of the steel cable passes around the fixed pulley and is wound on the strip panel. The rotating support includes a base and a rotating support. The base has a 90° sector-shaped cross section. The rotating support and the base are rotatably connected. The rotating support includes a support surface that can provide support for the strip panel and can rotate from a vertical state to a horizontal state.

[0006] The beneficial effects of this plan are:

[0007] 1. First, place the two straight edges of the rotating support between the curb and the floor, and rotate the support to make its support surface vertical, so that one end of the strip is against the support surface. Move the movable support to the other end of the strip, pass the steel cable through the fixed pulley and under the other end of the strip, and then loop it onto the strip. Then, the winch lifts the other end of the strip upwards, and the movable support moves towards the curb, with both the strip and the rotating support rotating around the base. Finally, push the strip horizontally onto the curb, and then install the strip on the curb. This method is convenient and quick, requiring no manual pry bar assistance, and has high construction efficiency.

[0008] 2. This avoids damaging the surface of the strips and curbs with a pry bar, thus reducing the appearance quality.

[0009] 3. The rotating support is easy to install; simply tighten it against the countersunk wall.

[0010] Furthermore, the cross-section of the rotating support is semi-circular, and the point where the rotating support and the base are rotatably connected is the rotation point, which is the intersection of the central axes of the cross-sections of the rotating support and the base. This design ensures that the support surface of the rotating support can rotate from vertical to horizontal without colliding with the curb or the floor.

[0011] Furthermore, the rotating support surface is provided with several conversion units, each including a conversion groove. The conversion groove includes a slider area and a roller area. With the support surface as the horizontal reference plane, the bottom of the slider area slopes downwards near the countersunk edge. A slider slides within the slider area, with its upper end horizontally positioned. A roller is rotatably connected within the roller area, capable of moving the strip plate onto the countersunk edge. Initially, the top of the slider is higher than the top of the roller. When the slider slides to its lowest position in the slider area, the top of the slider is lower than the top of the roller. This arrangement facilitates the horizontal movement of the strip plate onto the countersunk edge after it rotates to a vertical position.

[0012] Furthermore, the upper part of the movable support is provided with an adjustment unit, which includes a sensing unit, a rotating rod, and a transmission unit. The sensing unit is located on the upper part of the movable support and includes a fixed plate. A push plate is horizontally slidably connected to the fixed plate. The push plate protrudes from the side of the movable support closer to the strip plate. The side of the push plate closer to the strip plate is provided with a receiving groove for accommodating the vertical steel cable. An elastic element is provided between the push plate and the fixed plate. The push plate can push the upper end of the rotating rod to rotate. The lower part of the rotating rod is hinged to the movable support. A return torsion spring is provided at the hinge position. The return torsion spring can reset the rotating rod. The transmission unit includes a wheel assembly, a transmission gear assembly, a drive component, and a toggle block. The output shaft of the drive component, the transmission gear assembly, and the wheel assembly are sequentially powered. The lower end of the rotating rod can push the toggle block. The toggle block can switch the transmission ratio of the transmission gear assembly.

[0013] Furthermore, the actuating block has a vertical strip-shaped hole, and the bottom of the rotating rod has a horizontal actuating short rod, which is slidably disposed in the strip-shaped hole; the transmission unit includes a transmission box, the actuating block is slidably disposed in the transmission box, the actuating block has an actuating rod, and the end of the actuating rod has a connecting sleeve; the transmission box has a drive shaft and a driven shaft rotatably arranged in parallel, the end of the drive shaft is connected to the output shaft of the drive component, the drive shaft has a first drive gear and a second drive gear fixed on it, and the driven shaft has a first driven gear and a second driven gear rotatably connected to it, the first drive gear and the first driven gear mesh, the second drive gear and the second driven gear mesh, the transmission ratio of the first drive gear and the first driven gear is less than the transmission ratio of the second drive gear and the second driven gear, the connecting sleeve and the driven shaft are slidably connected by a spline, the connecting sleeve is disposed between the first driven gear and the second driven gear, and the connecting sleeve can be connected to the first driven gear or the second driven gear by a spline.

[0014] This solution also has the following effects:

[0015] In order to make it easier to climb up the mobile support and remove the steel cable after the strip is erected, the steel cable needs to be threaded under the strip before it is put on the strip. This way, after the strip is erected, the steel cable will be located on the side of the strip closest to the mobile support, making it easier to remove the steel cable.

[0016] During the upward lifting process of the steel cable, the cable is divided into four sections in sequence: the inclined section, the vertical section, the inclined lifting section, and the looping section. The inclined section is part of the steel cable between the winch and the fixed pulley, and it is set at an angle. The vertical section is part of the steel cable between the fixed pulley and the bottom of the bar, and it is usually set vertically. The inclined section is part of the steel cable below the bar, attached to the bottom of the bar. The looping section is part of the steel cable that wraps around the bar and is looped around the bar. The vertical section generates a vertical pulling force on the bar, which causes one end of the bar to move upward and eventually rotate to stand upright.

[0017] When the moving speed of the mobile support is inconsistent with the speed of the winch, the vertical pull section begins to tilt, generating some horizontal tension. When the horizontal tension exceeds the friction, it will cause the inclined lifting section and the lasso section to suddenly slide horizontally, causing the strip to collide with and be damaged by the mobile support. The sudden sliding also causes damage to the strip surface due to the abrupt change in the connection position between the lasso and the strip, as well as the displacement of the strip position caused by the sliding, which increases the workload of workers in correcting the strip later.

[0018] In this design, two sets of gears are used to create two different transmission ratios, which are switched between by a lever. Initially, the vertical pull section is vertically positioned. Tension in the vertical pull section pushes a push plate, causing the upper end of the rotating rod to rotate. This, in turn, drives the lower end of the rotating rod to push the lever. The power of the driving component is transmitted to the wheel assembly via the second driving gear and the second driven gear, allowing the moving bracket to advance slowly with a large torque. When the vertical pull section begins to tilt, the push plate resets under the action of the elastic element, and the rotating rod resets the lever under the action of the torsion spring. The power of the driving component is then transmitted to the wheel assembly via the first driving gear and the first driven gear, allowing the moving bracket to advance rapidly and restoring the vertical pull section to its vertical position.

[0019] Conversely, when the strip and the lasso section suddenly slide relative to each other, the vertical section uses tension to push the push plate, thereby pushing the upper end of the rotating rod to rotate, which in turn drives the lower end of the rotating rod to push the actuating block. The power of the driving component is transmitted to the wheel assembly through the second driving gear and the second driven gear, so that the moving bracket reduces its moving speed and avoids the moving bracket from colliding with the strip.

[0020] Furthermore, when the strip and the lasso section suddenly slide relative to each other, if the strip slides at the end away from the moving support, it will be difficult to push the rotating rod, thus making it impossible to switch the transmission ratio. In this solution, a rotating support is set to press against the end of the strip, thereby ensuring that the strip will only slide towards the side closer to the moving support, thus enabling timely switching of the transmission ratio.

[0021] Furthermore, by observing the relative positions of the rotating rod and the fixed plate, operators can gain a clearer understanding of the tilt of the vertical pull section and thus promptly control the drive components for adjustment.

[0022] This solution also aims to provide a construction method for an auxiliary device for installing ALC panels, which can directly install the panels on the curb.

[0023] To achieve the above objectives, the present invention adopts the following technical solution: a construction method for an auxiliary device for ALC panel installation, comprising the following steps:

[0024] Step 1: Place the two straight edges of the rotating support between the countersunk wall and the floor, and rotate the rotating support to make the support surface of the rotating support vertical. At this time, press the slider down so that the slider is located on the lower side of the conversion groove, and the slider protrudes away from the countersunk wall relative to the roller.

[0025] Step 2: Use a trolley to transport the strip to the construction position, and place one end of the strip against the support surface; move the movable bracket to the other end of the strip, pass the steel cable through the fixed pulley and through the underside of the other end of the strip, and then put it on the strip.

[0026] Step 3: The winch lifts the other end of the bar upwards, and at the same time, the drive unit moves the moving support towards the reverse curb. Both the bar and the rotating support rotate around the base.

[0027] Step 4: As the strip gradually rotates to a vertical position, the weight of the strip presses on the slider, causing the block to slide along the bottom of the conversion groove near the reverse curb. After the strip rotates to a vertical position, it continues to be pushed horizontally. The slider's support for the strip is converted into the roller's support for the strip, and the roller drives the strip to move horizontally onto the reverse curb. Attached Figure Description

[0038] Example

[0039] The implementation examples are basically as follows Figure 1-8 As shown: An auxiliary device for installing ALC strip panels, which assists in the installation of indoor strip panels 1. Several strip panels 1 are assembled to form a wall to serve as a partition. This solution is applicable to indoor locations with a backsplash 2. This embodiment includes a movable bracket 3 and a rotating support.

[0040] like Figure 1 As shown, the mobile support 3 is constructed from several steel pipes, including a lower rectangular frame 310 and an upper right-angled triangular frame 320. Two casters 311 are provided at the two corners on the lower left side of the rectangular frame 310. A transmission box 312 and a wheel assembly are provided on the right side of the rectangular frame 310. The transmission box 312 is welded to the bottom of the rectangular frame 310. The wheel assembly includes a drive shaft 450, a drive gear 451 is keyed to the drive shaft 450, the drive shaft 450 passes through the transmission box 312, and a drive wheel 452 is fixed at each end of the drive shaft 450. A winch 313 is bolted to the upper left side of the rectangular frame 310, and a steel cable 330 is wound on the winch 313. A crossbar 314 is welded to the upper right side of the rectangular frame 310.

[0041] A ladder is provided on the hypotenuse of the right-angled triangular frame 320. The ladder includes several horizontal bars 321 arranged linearly along the hypotenuse. All horizontal bars 321 are welded to the right-angled triangular frame 320. A fixed pulley 322 is rotatably connected to the top of the right-angled triangular frame 320. An adjustment unit is provided below the fixed pulley 322. The adjustment unit includes a sensing unit, a rotating rod 470 and a transmission unit. The sensing unit is located on the upper part of the movable support 3. The sensing unit includes a horizontally arranged fixed plate 340, which is welded to the right-angled triangular frame 320.

[0042] like Figure 1 and Figure 6 As shown, the fixed plate 340 has a sliding groove 341 and an oblique hole 342, with the oblique hole 342 penetrating the fixed plate 340 vertically. Figure 6 As shown, a guide groove 343 is opened on the bottom of both the upper and lower sides of the sliding groove 341. The guide groove 343 extends to the right beyond the right surface of the fixing plate 340. The portion of the fixing plate 340 between the two guide grooves 343 forms a limiting part 344. A strip-shaped vertical through hole 345 is opened in the middle of the sliding groove 341. A push plate 350 is slidably connected inside the sliding groove 341. Figure 1 As shown, an elastic element 351, which is a spring, is adhered between the left side of the push plate 350 and the side wall of the sliding groove 341. The push plate 350 protrudes relative to the right side of the movable bracket 3. Figure 1 , Figure 6 As shown, the push plate 350 has a limiting hole 352, which can accommodate the limiting part 344. The lower surface of the push plate 350 is provided with two guide protrusions 353, which are slidably disposed in the guide groove 343. The right surface of the push plate 350 has a vertical receiving groove 354, which can accommodate the steel cable 330.

[0043] like Figure 1 As shown, the upper end of the rotating rod 470 passes through the vertical through hole 345, and the push plate 350 can push the upper end of the rotating rod 470; the horizontal rod 314 passes through the middle of the rotating rod 470 and is rotatably connected to the rotating rod 470; a return torsion spring (not shown in the figure) is provided between the horizontal rod 314 and the rotating rod 470, and the return torsion spring can make the rotating rod 470 return to the vertical state; the lower end of the rotating rod 470 is inserted into the transmission box 312.

[0044] The transmission unit is installed inside the transmission box 312. The transmission unit includes a transmission gear assembly, a drive component 410, and a toggle block 460. The output shaft of the drive component 410, the transmission gear assembly, and the wheel assembly are connected in sequence. The lower end of the rotating rod 470 can push the toggle block 460, and the toggle block 460 can switch the transmission ratio of the transmission gear assembly.

[0045] Specifically, such as Figure 7As shown, the drive component 410 is a servo motor, bolted into the transmission box 312. The transmission gear assembly includes a drive shaft 420, a driven shaft 430, and an intermediate shaft 440. The left end of the drive shaft 420, the left end of the driven shaft 430, the rear end of the intermediate shaft 440, and the drive shaft 450 are all rotatably connected to the inner wall of the transmission box 312. The inner wall of the transmission box 312 is welded to the left end of the guide rod 472. The guide rod 472 passes through the toggle block 460 and is slidably connected to the toggle block 460. The drive shaft 420, the driven shaft 430, and the guide rod 472 are parallel. The drive shaft 450 and the intermediate shaft 440 are parallel. The driven shaft 430 and the intermediate shaft 440 are perpendicular. In this design, bearings are used to support the shafts.

[0046] The actuating block 460 has a vertical slotted hole 461. A horizontal actuating rod 471 is integrally formed at the bottom of the rotating rod 470. The actuating rod 471 is slidably disposed within the slotted hole 461. An actuating rod 462 is welded to the actuating block 460. A connecting sleeve 463 is welded to the end of the actuating rod 462. The connecting sleeve 463 is slidably disposed on the driven shaft 430 and keyed to the driven shaft 430. The end of the driving shaft 420 is keyed to the output shaft of the driving component 410. A first driving gear 421 and a second driving gear 422 are fixed sequentially from left to right on the driving shaft 420. A first driven gear 431 and a second driven gear 43 are rotatably connected sequentially from left to right on the driven shaft 430. 2. The first driving gear 421 and the first driven gear 431 mesh with a transmission ratio of 0.5. The second driving gear 422 and the second driven gear 432 mesh with a transmission ratio of 2. The coupling sleeve 463 is disposed between the first driven gear 431 and the second driven gear 432. The coupling sleeve 463 can be connected to the first driven gear 431 or the second driven gear 432 through a spline. The right end of the driven shaft 430 is keyed to the driven bevel gear 433. The intermediate shaft 440 is keyed to the intermediate bevel gear 441 and the intermediate gear 442 from front to back. The driven bevel gear 433 and the intermediate bevel gear 441 mesh, and the intermediate gear 442 meshes with the drive gear 451.

[0047] The rotating support includes a base 510, a rotating support 520, and a rotating shaft 512, such as Figure 8 As shown, the base 510 has a 90° sector-shaped cross-section, and a sector-shaped rotating groove 511 is formed on the base 510. The two ends of the rotating shaft 512 are welded to the side walls of the rotating groove 511, as shown. Figure 5 As shown, the rotating shaft 512 passes through and is rotatably connected to the rotating support 520. The rotating support 520 is a horizontally arranged strip with a semi-circular cross-section. The central axis of the rotating shaft 512 is the intersection of the central axes of the cross-sections of the rotating support 520 and the base 510. The rotating support 520 includes a support surface 521, which is a plane on the upper side of the rotating support 520, providing support for the end of the strip 1. Figures 2-5The support surface 521 can rotate from a vertical state to a horizontal state.

[0048] like Figure 5 As shown, the rotating support 520 is equipped with a limiting baffle 522 and three conversion units. The limiting baffle 522 is integrally formed on the leftmost side of the support surface 521 to prevent the strip 1 from sliding to the left during rotation. Each conversion unit includes a conversion groove, which is opened on the support surface 521. With the support surface 521 as the horizontal reference plane, the conversion groove includes a slider area 531 and a roller area 532 from left to right. A limiting protrusion 533 is provided between the slider area 531 and the roller area 532. The limiting protrusion 533 is integrally formed with the bottom of the conversion groove. The bottom right side of the slider area 531 faces downward. The slider 534 is inclined and located within the slider area 531. The slider 534 is slidably positioned within the slider area 531 and has a convex cross-section. The inner cross-section of the slider area 531 and the slider 534 cooperate with each other, creating friction between the slider 534 and the inner wall of the slider area 531. When the construction worker applies sufficient horizontal thrust to the slider 534, it can slide within the slider area 531. The upper end of the slider 534 is horizontally positioned. A roller 535 is rotatably connected within the roller area 532, and the roller 535 can move the strip 1 onto the countersunk 2. In the initial state, if... Figure 2 and Figure 4 As shown, the support surface 521 is vertical, and the slider 534 is located at the lower end of the slider area 531. The slider 534 protrudes to the left relative to the roller 535. When the support surface 521 rotates to a horizontal state, as shown... Figure 3 and Figure 5 As shown, when slider 534 slides to the lowest position in slider area 531, that is, the right end of the slider area, the top of slider 534 is lower than the top of roller 535.

[0049] The usage method of an auxiliary device and construction method for installing ALC strip 1 is as follows:

[0050] Step 1: Place the two straight edges of the rotating support between the countersunk 2 and the floor, and rotate the rotating support 520 so that the support surface 521 of the rotating support 520 is vertical. At this time, press the slider 534 down so that the slider 534 is located on the lower side of the conversion groove, and the slider 534 protrudes away from the countersunk 2 relative to the roller 535.

[0051] Step 2: Use a trolley to transport strip 1 to the construction position, aligning one end of strip 1 with the support surface 521; move the movable bracket 3 to the other end of strip 1, pass the steel cable 330 through the inclined hole 342 and the fixed pulley 322, and then thread it through the underside of the other end of strip 1 before looping it onto strip 1. Figure 2 As shown;

[0052] Step 3: The winch 313 lifts the other end of the bar plate 1 upwards. At the same time, the drive component 410 drives the moving bracket 3 to move closer to the anti-sill 2. The bar plate 1 and the rotating support 520 both rotate around the base 510.

[0053] Step 4: As strip 1 gradually rotates to a vertical position, the weight of strip 1 presses down on slider 534, as... Figure 3 As shown, the block slides along the bottom of the conversion groove near the side of the reverse slope 2. After the strip 1 is rotated to the vertical position, the strip 1 is pushed horizontally. The support of the slider 534 on the strip 1 is converted into the support of the roller 535 on the strip 1. The roller 535 drives the strip 1 to move horizontally onto the reverse slope 2.

[0054] This solution also has the following effects:

[0055] In order to facilitate climbing up the movable support 3 to remove the steel cable 330 after the strip 1 is erected, the steel cable 330 needs to be threaded under the strip 1 before it is put on the strip 1. In this way, after the strip 1 is erected, the steel cable 330 will be located on the side of the strip 1 closest to the movable support 3, which will make it easier to remove the steel cable 330.

[0056] During the upward lifting process of the steel cable 330, the steel cable 330 is divided into a diagonal section 331, a vertical section 332, a diagonal lifting section 333, and a loop section 334. The diagonal section 331 is the part of the steel cable 330 between the winch 313 and the fixed pulley 322, which is set at an angle. The vertical section 332 is the part of the steel cable 330 below the fixed pulley 322 and the bar plate 1, which is usually set vertically. The diagonal section is the part of the steel cable 330 below the bar plate 1, which is attached to the bottom of the bar plate 1. The loop section 334 is the part of the steel cable 330 that wraps around the bar plate 1. The vertical section 332 generates a vertical pulling force on the bar plate 1, which causes one end of the bar plate 1 to move upward and eventually rotate to stand upright.

[0057] When the moving speed of the movable support 3 and the speed of the winch 313 are inconsistent, the vertical pull section 332 begins to tilt, and the vertical pull section 332 generates a partial horizontal tension. When the horizontal tension is greater than the friction, it will cause the inclined lifting section 333 and the lasso section 334 to suddenly slide in the horizontal direction, thereby causing the strip 1 and the movable support 3 to collide and be damaged. The sudden sliding also causes damage to the surface of the strip 1 due to the abrupt change in the connection position between the lasso and the strip 1, and the displacement of the strip 1 caused by the sliding increases the workload of the workers to correct the strip 1 later.

[0058] In this design, two sets of gears are used to form two different transmission ratios, which are switched between by a lever 460. Initially, the vertical pull section 332 is vertically positioned. The vertical section uses tension to push the push plate 350, thereby rotating the upper end of the rotating rod 470. This, in turn, drives the lower end of the rotating rod 470 to push the lever 460. The power of the driving component 410 is transmitted to the wheel assembly through the second driving gear 422 and the second driven gear 432, causing the moving bracket 3 to advance slowly with a large torque. When the vertical pull section 332 begins to tilt, the push plate 350 resets under the action of the elastic element 351, and the rotating rod 470 resets under the action of the torsion spring. The power of the driving component 410 is transmitted to the wheel assembly through the first driving gear 421 and the first driven gear 431, causing the moving bracket 3 to advance rapidly, and the vertical pull section 332 returns to a vertical position.

[0059] Conversely, when the strip 1 and the lasso section 334 suddenly slide relative to each other, the vertical section uses tension to push the push plate 350, thereby pushing the upper end of the rotating rod 470 to rotate, which in turn drives the lower end of the rotating rod 470 to push the actuating block 460. The power of the driving member 410 is transmitted to the wheel assembly through the second driving gear 422 and the second driven gear 432, so that the moving bracket 3 reduces its moving speed and avoids the moving bracket 3 from colliding with the strip 1.

[0060] Furthermore, when the strip 1 and the lasso section 334 suddenly slide relative to each other, if the end of the strip 1 that is away from the moving support 3 slides, it will be difficult to push the rotating rod 470, thus making it impossible to switch the transmission ratio. In this solution, a rotating support is set to press against the end of the strip 1, thereby ensuring that the strip 1 will only slide towards the side closer to the moving support 3, thus switching the transmission ratio in time.

[0061] Furthermore, by observing the relative positions of the rotating rod 470 and the fixed plate 340, the operator can gain a clearer understanding of the tilt of the vertical section 332, and then promptly control the drive component 410 to make adjustments. Whether the vertical section 332 is vertical is a relative concept, and the main purpose is to keep it as vertical as possible during construction.

The push plate can push the upper end of the rotating rod to rotate. The lower part of the rotating rod is hinged to the movable support. A return torsion spring is provided at the hinge position, which can reset the rotating rod. The transmission unit includes a wheel assembly, a transmission gear assembly, a drive component, and a toggle block. The output shaft of the drive component, the transmission gear assembly, and the wheel assembly are connected in sequence. The lower end of the rotating rod can push the toggle block, which can switch the transmission ratio of the transmission gear assembly.

3. The auxiliary device for ALC strip installation according to claim 2, characterized in that: The actuating block has a vertical slotted hole, and the bottom of the rotating rod has a horizontal actuating short rod, which is slidably disposed in the slotted hole. The transmission unit includes a transmission box, and the actuating block is slidably disposed in the transmission box. The actuating block has an actuating rod, and the end of the actuating rod has a connecting sleeve. The transmission box contains a drive shaft and a driven shaft arranged in parallel. The end of the drive shaft is connected to the output shaft of the drive component. A first drive gear and a second drive gear are fixed on the drive shaft. A first driven gear and a second driven gear are rotatably connected to the driven shaft.

The connecting sleeve and the driven shaft are slidably connected by a spline. The connecting sleeve is disposed between the first driven gear and the second driven gear and can be connected to the first driven gear or the second driven gear by a spline.

4. The construction method of the auxiliary device for ALC strip installation according to claim 3, characterized in that, Includes the following steps: Step 1: Place the two straight edges of the rotating support between the countersunk wall and the floor, and rotate the rotating support to make the support surface of the rotating support vertical. At this time, press the slider down so that the slider is located on the lower side of the conversion groove, and the slider protrudes away from the countersunk wall relative to the roller. Step 2: Use a trolley to transport the strip to the construction position, and place one end of the strip against the support surface; move the movable bracket to the other end of the strip, pass the steel cable through the fixed pulley and through the underside of the other end of the strip, and then put it on the strip. Step 3: The winch lifts the other end of the bar upwards, and at the same time, the drive unit moves the moving support towards the reverse curb. Both the bar and the rotating support rotate around the base. Step 4: As the strip gradually rotates to a vertical position, the weight of the strip presses on the slider, causing the block to slide along the bottom of the conversion groove near the reverse curb. After the strip rotates to a vertical position, it continues to be pushed horizontally. The slider's support for the strip is converted into the roller's support for the strip, and the roller drives the strip to move horizontally onto the reverse curb.
