Description

Technical Field

[0001] The present invention relates to the technical field of steel caissons, and more particularly, to a method for assembling steel caisson members. Background Art

[0002] Currently, steel caisson members are usually divided into wall plate units, transverse stiffeners, and connecting angle steels. When manufacturing the plate units, the transverse stiffeners are usually assembled together with the inner and outer wall plate units. When assembling the members, the connecting angle steels are in loose pieces and are assembled separately. This results in difficult positioning of the wall plate units during member assembly, and temporary supports or process partitions must be used for support to ensure the assembly accuracy of the members. However, the use of process partitions and temporary supports requires additional processes for disassembling and assembling the process partitions and temporary supports, increasing the assembly time and relatively low efficiency. Summary of the Invention

[0003] The problem solved by the present invention is: how to improve the assembly efficiency of steel caisson members.

[0004] To solve the above problems, the present invention provides a method for assembling steel caisson members, including:

[0005] Pre-assembling the transverse stiffeners and connecting angle steels that make up the steel caisson members to obtain a truss plate unit;

[0006] Assembling the lower wall plate units that make up the steel caisson members, and vertically positioning and installing multiple truss plate units on the lower wall plate units;

[0007] Connecting the upper wall plate units that make up the steel caisson members to the ends of multiple truss plate units away from the lower wall plate units.

[0008] Optionally, before pre-assembling the transverse stiffeners and connecting angle steels that make up the steel caisson members, it includes:

[0010] Optionally, it includes installing magnetic supports and magnetic stoppers on the pre-assembly platform. The magnetic supports and the magnetic stoppers are distributed along the reference line respectively. The magnetic supports are used to magnetically attract and support the transverse stiffeners, and the magnetic stoppers are used to magnetically attract and position the transverse stiffeners and the connecting angle steels.

[0011] Optionally, the magnetic support includes a first base and a first magnetic head. The first magnetic head is snap-fitted and positioned with the first base, and the end of the first magnetic head away from the first base is provided with a planar structure.

[0012] Optionally, the magnetic attraction stop block includes a second base and a second magnetic attraction head. The second magnetic attraction head is clamped and positioned with the second base. A positioning notch is provided at an end of the second magnetic attraction head away from the second base, and the positioning notch is clamped with the transverse stiffener or with the connecting angle steel.

[0013] Optionally, the positioning notch includes a first plane arranged horizontally and a second plane perpendicular to the first plane. A standard line is provided on the second base, and the standard line is used to be coplanar with the second plane.

[0014] Optionally, after vertically positioning and installing a plurality of the girder plate units on the lower wall plate unit, and before connecting the upper wall plate unit forming the steel caisson member with the ends of the plurality of girder plate units away from the lower wall plate unit, it further includes:

The first cross beam and the second cross beam are respectively perpendicularly connected to the two columns, and the first cross beam is vertically movably arranged along the axis of the column. A plurality of the sliders are respectively slidably arranged on the first cross beam and the second cross beam.

[0017] Optionally, the adjusting device further includes a steel wire rope. A scale line is provided on the first cross beam, and the scale line is distributed along the sliding direction of the slider. The steel wire rope is straightened and is used to be connected to two scale lines at the same position in the first cross beams of the two adjusting devices, so as to measure and compare the horizontal distances between the two transverse stiffeners of the girder plate unit and the steel wire rope.

[0018] Optionally, a locking device is further included, and the locking device is used to lock the slider.

[0043] It should be noted that the terms "first", "second", etc. in the description, claims, and above-mentioned accompanying drawings of the present invention are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein.

[0044] Combined with Figures 1 to 3 As shown, an embodiment of the present invention provides a method for assembling steel caisson members, including:

[0045] Pre-assemble the transverse stiffener 1 and the connecting angle steel 2 that make up the steel caisson members to obtain the truss plate unit 3;

[0046] Assemble the lower wall plate unit 4 that makes up the steel caisson members, and vertically position and install multiple truss plate units 3 on the lower wall plate unit 4;

[0047] Connect the upper wall plate unit 5 that makes up the steel caisson members to the ends of multiple truss plate units 3 that are away from the lower wall plate unit 4.

[0048] Specifically, the steel caisson member is composed of multiple segments. Each segment may include several parts such as a transverse stiffener 1, a connecting angle steel 2, an upper wall plate unit 5, and a lower wall plate unit 4. Among them, the upper wall plate unit 5 includes an upper wall plate and multiple stiffeners vertically installed on the upper wall plate. Similarly, the lower wall plate unit 4 includes a lower wall plate and multiple stiffeners vertically installed on the lower wall plate. Multiple positioning openings are provided on the transverse stiffener 1, and the positioning openings are used for snap-fitting and positioning with the stiffeners on the lower wall plate unit 4 or with the stiffeners on the upper wall plate unit 5. Within the same segment, the transverse stiffener 1 connected to the upper wall plate unit 5 and the transverse stiffener 1 connected to the lower wall plate unit 4 are connected and fixed by the connecting angle steel 2. When assembling the steel caisson member, first pre-assemble the transverse stiffener 1 and the connecting angle steel 2 that make up the steel caisson member to obtain the truss plate unit 3. The structure of the truss plate unit 3 refers to Figure 3 as shown, and assemble the lower wall plate unit 4 on the anti-deformation jig. The assembly process of the lower wall plate unit 4 is as follows: Fix the lower wall plate of the lower wall plate unit 4 on the anti-deformation jig, and weld multiple stiffeners at the upper end of the lower wall plate. The structure of the lower wall plate unit 4 is as Figure 2 shown. Fix the assembled lower wall plate unit 4 and make the multiple stiffeners on the lower wall plate unit 4 face upward, as Figure 9 shown. Then, as Figure 10 shown, set the truss plate unit 3 vertically and perpendicular to the lower wall plate unit 4. After that, snap-fittingly position and install the lower transverse stiffener 1 in the truss plate unit 3 with the multiple stiffeners on the lower wall plate unit 4. Thereafter, gradually position and install multiple truss units 3 on the lower wall plate unit 4 in sequence according to the above process, as Figure 13 shown. After multiple truss units 3 jointly form a support structure on the lower wall plate unit 4, then as Figure 14 shown. Finally, snap-fittingly install the multiple stiffeners on the upper wall plate unit 5 at the ends of multiple truss plate units 3 away from the lower wall plate unit 4. That is, position and install the upper wall plate unit 5 on the multiple upper transverse stiffeners 1 in the truss plate unit 3. During the installation process, multiple truss units 3 can provide support and positioning during the installation of the upper wall plate unit 5, ensuring the installation accuracy while also reducing the use of process partitions and temporary supports, eliminating the processes of installing and removing process partitions and temporary supports, saving materials, and improving the manufacturing efficiency.

[0049] Therefore, in this embodiment, by pre-assembling the transverse stiffener 1 and the connecting angle steel 2, the truss plate unit 3 is obtained, and a plurality of truss plate units 3 are vertically positioned and installed on the lower wall plate unit 4. A plurality of truss plate units 3 can pre-form a positioning and installation inner tire support on the lower wall plate unit 4, so as to eliminate the use of process partitions and temporary supports in the traditional process. Furthermore, after connecting the upper wall plate unit 5 of the steel caisson member to the end of a plurality of truss plate units 3 away from the lower wall plate unit 4, the installation process of the upper wall plate unit 5 can be completed, thus saving the processes of disassembling and assembling the process partitions and temporary supports in the traditional process, saving the assembly time, and further improving the assembly and manufacturing efficiency of the steel caisson member.

[0050] Based on the above embodiment, as Figure 13 shown, the steel caisson member assembly method provided by the embodiment of the present invention may further include hoisting the auxiliary angle steel 12. The hoisting of the auxiliary angle steel 12 is before the installation of the upper wall plate unit 5, that is, after a plurality of truss plate units 3 are installed on the lower wall plate unit 4, the auxiliary angle steel 12 is installed at the connection position of each truss plate unit 3 and the upper wall plate unit 5 by hoisting. The auxiliary angle steel 12 can also be connected to the upper wall plate unit 5. In this way, the auxiliary angle steel 12 can provide additional constraints and improve the connection stability between the truss plate unit 3 and the upper wall plate unit 5.

[0051] Still based on the above embodiment, as Figure 10 shown, the steel caisson member assembly method provided by the embodiment of the present invention further includes that during the installation process of each truss plate unit 3, a support rod 13 can be arranged on the side of the truss plate unit 3 to prevent the truss plate unit 3 from tipping over.

[0052] Also based on the above embodiment, as Figures 5 to 8 shown, Figure 5 is a structural schematic diagram of the plate tooth 14 in the truss plate unit 3. If the truss plate unit 3 includes the structure of the plate tooth 14 in this embodiment, after the plate tooth 14 is preferentially assembled, the assembly of the truss plate unit 3 is completed in the order as Figures 6 to 8 shown. The function of such an assembly order is that the assembly of the truss plate unit 3 is gradually completed with the special-shaped plate tooth 14 as the benchmark, which can ensure the assembly accuracy.

[0053] Optionally, as combined with Figure 3 shown, before pre-assembling the transverse stiffener 1 and the connecting angle steel 2 that make up the steel caisson member, it includes:

[0054] Draw a reference line 6 on the pre-assembly platform, and position the transverse stiffener 1 and the connecting angle steel 2 along the reference line 6 respectively before pre-assembling. Among them, the reference line 6 at least includes partial contour lines of the transverse stiffener 1 and the connecting angle steel 2 in the truss plate unit 3.

[0055] Specifically, Figure 3 in Figure 3 , a is the structural design drawing after the assembly of the transverse stiffener 1 and the connecting angle steel 2 in the required girder plate unit 3. According to this design drawing, a reference line 6 is drawn on the pre-assembly platform, as Figure 3 shown in b of Figure 3 . The reference line 6 at least includes partial contour lines of the transverse stiffener 1 and the connecting angle steel 2 in the girder plate unit 3. For example, the reference line 6 can be drawn along the long side of the transverse stiffener 1, and the reference line 6 can also be drawn along the long side of the connecting angle steel 2. After the reference line 6 is drawn, during assembly, only the long sides of the transverse stiffener 1 and the connecting angle steel 2 need to be aligned with the corresponding reference line 6 respectively for assembly, thereby reducing the initial positioning time of the transverse stiffener 1 and the connecting angle steel 2 to improve the assembly efficiency.

[0056] In this way, by drawing the reference line 6 on the pre-assembly platform and pre-assembling after the transverse stiffener 1 and the connecting angle steel 2 are respectively positioned along the reference line 6, the initial positioning time of the transverse stiffener 1 and the connecting angle steel 2 can be reduced to improve the assembly efficiency.

[0057] Optionally, as Figure 4 shown, the steel caisson member assembly method includes installing magnetic adsorption piers 7 and magnetic adsorption blocks 8 on the pre-assembly platform. The magnetic adsorption piers 7 and the magnetic adsorption blocks 8 are respectively distributed along the reference line 6. The magnetic adsorption piers 7 are used to magnetically adsorb and support the transverse stiffener 1, and the magnetic adsorption blocks 8 are used to magnetically adsorb and position the transverse stiffener 1 and the connecting angle steel 2.

[0058] Specifically, after the reference line 6 is drawn, magnetic adsorption piers 7 and magnetic adsorption blocks 8 are respectively installed on both sides of the reference line 6 corresponding to the transverse stiffener 1. The magnetic adsorption piers 7 are used to magnetically adsorb and support the transverse stiffener 1, and the magnetic adsorption blocks 8 are used to magnetically adsorb and limit the long side of the transverse stiffener 1 to be aligned with the reference line 6 to ensure the positioning accuracy of the transverse stiffener 1. Similarly, the magnetic adsorption blocks 8 are used to magnetically adsorb and limit the long side of the connecting angle steel 2 to be aligned with the reference line 6 to ensure the positioning accuracy of the connecting angle steel 2. During the process of assembling the girder plate unit 3, the magnetic adsorption piers 7 and the magnetic adsorption blocks 8 can realize the support and positioning of the transverse stiffener 1 and the connecting angle steel 2 through magnetic adsorption, and after the girder plate unit 3 is assembled, the magnetic adsorption piers 7 and the magnetic adsorption blocks 8 can be reused, saving costs.

[0059] In this way, by installing magnetic adsorption piers 7 and magnetic adsorption blocks 8 on the pre-assembly platform and the magnetic adsorption piers 7 and the magnetic adsorption blocks 8 are respectively distributed along the reference line 6, the positioning accuracy of the transverse stiffener 1 and the connecting angle steel 2 during the assembly process can be improved to improve the assembly efficiency of the girder plate unit 3.

[0060] Optionally, in combination with Figure 16 shown, the magnetic adsorption pier 7 includes a first base 71 and a first magnetic adsorption head 72. The first magnetic adsorption head 72 is clamped and positioned with the first base 71, and the end of the first magnetic adsorption head 72 away from the first base 71 is set as a planar structure 721.

[0061] Specifically, Figure 16 In a, it is a structural schematic diagram of the first base 71 and the first magnetic suction head 72. The bottom of the first base 71 is fixed. After the top of the first base 71 is clamped with the bottom of the first magnetic suction head 72, it is fixed by a pin shaft, as Figure 16 shown in b. The top of the first magnetic suction head 72 is a planar structure 721, and this planar structure 721 can abut against the transverse stiffener 1.

[0062] In this way, by clamping and positioning the first magnetic suction head 72 with the first base 71, the fixation of the first magnetic suction head 72 can be realized, and the end of the first magnetic suction head 72 far from the first base 71 is set as the planar structure 721. The planar structure 721 can improve the magnetic suction stability between the first magnetic suction head 72 and the transverse stiffener 1.

[0063] Optionally, in combination with Figure 17 shown, the magnetic suction block 8 includes a second base 81 and a second magnetic suction head 82. The second magnetic suction head 82 is clamped and positioned with the second base 81. A positioning notch 821 is provided at the end of the second magnetic suction head 82 far from the second base 81, and the positioning notch 821 is clamped with the transverse stiffener 1 or with the connecting angle steel 2.

[0064] Specifically, Figure 17 In a, it is a structural schematic diagram of the second base 81 and the second magnetic suction head 82. Figure 17 In b, it is a structural schematic diagram after the second base 81 and the second magnetic suction head 82 are clamped. The second base 81 can be similar to the structure of the first base 71. After the top of the second base 81 is clamped with the bottom of the second magnetic suction head 82, it is fixed by a pin shaft. A positioning notch 821 is provided at the top end of the second magnetic suction head 82, and the positioning notch 821 is clamped with the transverse stiffener 1 or with the connecting angle steel 2.

[0065] In this way, by clamping and positioning the second magnetic suction head 82 with the second base 81, a positioning notch 821 is provided at the end of the second magnetic suction head 82 far from the second base 81, and the positioning notch 821 is clamped with the transverse stiffener 1 or with the connecting angle steel 2. Thus, not only can the transverse stiffener 1 or the connecting angle steel 2 be supported by the magnetic suction effect of the second magnetic suction head 82, but also the horizontal positioning of the transverse stiffener 1 or the connecting angle steel 2 can be ensured through the positioning notch 821 provided on the second magnetic suction head 82, thereby improving the positioning accuracy of the transverse stiffener 1 or the connecting angle steel 2.

[0066] Optionally, in combination with Figure 17As shown, the positioning notch 821 includes a first plane 8211 arranged horizontally and a second plane 8212 perpendicular to the first plane 8211. A reference line 811 is provided on the second base 81, and the reference line 811 is used to be coplanar with the second plane 8212. Among them, the first plane 8211 is used to abut against the bottom end of the transverse stiffener 1 or the connecting angle steel 2, and the second plane 8212 is used to abut against the side end of the transverse stiffener 1 or the connecting angle steel 2.

[0067] Specifically, as Figure 17 shown in b of, the first plane 8211 is perpendicular to the second plane 8212, and the first plane 8211 and the second plane 8212 form the positioning notch 821 described above. A reference line 811 is provided on the second base 81, and the reference line 811 is arranged coplanarly with the second plane 8212 in the vertical direction. Taking the transverse stiffener 1 as an example, the transverse stiffener 1 can be a cuboid structure. During use, the first plane 8211 abuts against the bottom end of the transverse stiffener 1 to support the transverse stiffener 1, and the second plane 8212 abuts against the side end of the transverse stiffener 1 to limit the horizontal position of the transverse stiffener 1. If the second plane 8212 is inclined in the vertical direction, the second plane 8212 is not coplanar with the reference line 811, and the second plane 8212 needs to be corrected in time to ensure the accuracy of the horizontal limitation of the transverse stiffener 1 by the second plane 8212.

[0068] In this way, by providing the reference line 811 on the second base 81, and the reference line 811 is used to be coplanar with the second plane 8212, the verticality of the second plane 8212 can be verified through the reference line 811 to ensure the stability of the horizontal limitation of the transverse stiffener 1 or the connecting angle steel 2 by the second plane 8212, and further ensure the use stability of the positioning notch 821.

[0069] Optionally, as shown in combination with Figures 9 to 15 , after vertically positioning and installing a plurality of truss plate units 3 on the lower wall plate unit 4 and before connecting the upper wall plate unit 5 forming the steel caisson member to the end of the plurality of truss plate units 3 away from the lower wall plate unit 4, it further includes:

[0070] Adjusting devices 9 are respectively arranged at both ends along the length direction of the plurality of truss plate units 3. The adjusting device 9 is provided with a slider 91 that slides along a direction perpendicular to the length direction of the plurality of truss plate units 3, and the sliders 91 on the two adjusting devices 9 are clamped with the transverse stiffeners 1 in each truss plate unit 3.

[0071] Specifically, the length direction of the multiple girder plate units 3 is the X-axis direction. The multiple girder plate units 3 are located between two adjusting devices 9. Each adjusting device 9 is provided with a slider 91, and the slider 91 can be clamped with the transverse stiffeners 1 in each girder plate unit 3. For example, the slider 91 in the adjusting device 9 can be clamped with the upper transverse stiffener 1 in each girder plate unit 3 and also with the lower transverse stiffener 1 in each girder plate unit 3. Among them, the clamping method between the slider 91 and the transverse stiffener 1 can be: the slider 91 can be provided with a groove, the notch of the groove faces the girder plate unit 3, and the groove runs through the slider 91 in the vertical direction. By clamping the transverse stiffener 1 of the girder plate unit 3 into the corresponding groove on the slider 91, the vertical positioning of the girder plate unit 3 can be realized, and the girder plate unit 3 can be prevented from tilting. The number of sliders 91 in the adjusting device 9 can correspond to the number of girder plate units 3, and both ends of each girder plate unit 3 are used for positioning through the corresponding sliders 91 in the two adjusting devices 9.

[0072] In this way, by arranging two adjusting devices 9 along the length direction of the multiple girder plate units 3 and clamping the sliders 91 on the two adjusting devices 9 with the transverse stiffeners 1 in each girder plate unit 3, the sliders 91 in the two adjusting devices 9 can realize the positioning of the girder plate units 3, prevent the girder plate units 3 from tilting, and ensure the stability of the girder plate units 3.

[0073] Based on the setting of the two adjusting devices 9, as shown in Figures 9 to 15 After the lower wall plate unit 4 is assembled, place the two adjusting devices 9 at both ends in the length direction of the lower wall plate unit 4. After installing the first girder plate unit 3 on the lower wall plate unit 4, as shown in Figure 10 After the sliders on the two adjusting devices 9 are clamped with the transverse stiffeners 1 of the first girder plate unit 3, and after ensuring that the first girder plate unit 3 is vertical, install the second girder plate unit 3. Repeat this process. As shown in Figures 11 to 13 After the two adjusting devices 9 complete the positioning and installation of the multiple girder plate units 3, and as shown in Figures 14 to 15 After the upper wall plate unit 5 is installed, move the two adjusting devices 9 away to facilitate the movement of the upper wall plate unit 4 and the girder plate units 3.

[0074] Optionally, as shown in Figure 18 Each adjusting device 9 includes two moving wheel groups 92, two columns 93, a first cross beam 94 and a second cross beam 95. The two columns 93 are vertical and are respectively installed on the two moving wheel groups 92. The first cross beam 94 and the second cross beam 95 are respectively perpendicularly connected to the two columns 93, and the first cross beam 94 is vertically movably arranged along the axis of the column 93. Multiple sliders 91 are respectively slidably arranged on the first cross beam 94 and the second cross beam 95.

[0075] Specifically, the two moving wheel sets 92 enable the flexible use of the adjusting device 9. Each moving wheel set 92 is connected to a vertical column 93. The vertical columns 93 are vertical. In each adjusting device 9, the first cross beam 94 and the second cross beam 95 are respectively perpendicular to the two vertical columns 93. A plurality of sliders 91 are sleeved on the first cross beam 94 and the second cross beam 95 respectively. The plurality of sliders 91 on the first cross beam 94 slide along the axial direction of the first cross beam 94, and the plurality of sliders 91 on the second cross beam 95 slide along the axial direction of the second cross beam 95. During the vertical positioning process of each truss plate unit 3, in one adjusting device 9, the slider 91 on the second cross beam 95 is clamped to the end of the lower horizontal stiffener 1 in the truss plate unit 3 by sliding, and the first cross beam 94 slides along the axial direction of the two vertical columns 93. After adjusting the height of the slider 91 on the first cross beam 94, the slider 91 on the first cross beam 94 is clamped to the end of the upper horizontal stiffener 1 in the truss plate unit 3 by sliding. The other adjusting device 9 is also used according to the above process.

[0076] In this way, by vertically installing the two vertical columns 93 on the two moving wheel sets 92 respectively, the two moving wheel sets 92 can realize the free movement of the adjusting device 9 to improve the flexibility of use. And by connecting the first cross beam 94 and the second cross beam 95 perpendicular to the two vertical columns 93 respectively, and setting the first cross beam 94 to move vertically along the axis of the vertical column 93, the first cross beam 94 can move up and down to adapt to the truss plate units 3 of different heights. Thus, after a plurality of sliders 91 are respectively slidably arranged on the first cross beam 94 and the second cross beam 95, the flexibility of use of the adjusting device can be improved by the sliding of the sliders 91.

[0077] Optionally, as shown in Figure 12 、 Figure 18 and Figure 19 the adjusting device 9 further includes a steel wire rope 10. A scale line 96 is arranged on the first cross beam 94. The scale line 96 is distributed along the sliding direction of the slider 91. The steel wire rope 10 is straightened and used to connect the two scale lines 96 at the same position on the first cross beams 94 of the two adjusting devices 9 for measuring and comparing the horizontal distances between the two horizontal stiffeners 1 of the truss plate unit 3 and the steel wire rope 10.

[0078] Specifically, as shown in Figure 19 a scale line 96 is arranged on the first cross beam 94. The scale line 96 is distributed along the sliding direction of the block 91. As shown in Figure 12As shown, after multiple girder plate units 3 are vertically fixed by two adjusting devices 9 respectively, the steel wire rope 10 is straightened, and the two ends of the steel wire rope 10 are respectively connected to two scale lines 96 at the same position on two first cross beams 94. Then, by moving the two first cross beams 94 up and down, the horizontal distances between the upper and lower transverse stiffeners 1 of the girder plate unit 3 and the steel wire rope 10 are measured and compared respectively. If it is found after measurement that the horizontal distances between the two transverse stiffeners 1 and the steel wire rope 10 are not the same, it means that the two transverse stiffeners 1 are not coplanar, that is, the girder plate unit 3 is inclined, and the position of the girder plate unit 3 needs to be readjusted to make the girder plate unit 3 keep vertical, further ensuring the flatness of each girder plate unit 3. In addition, another function of the scale line 96 is that during the installation process of the girder plate unit 3, after the previous adjusting device 9 is clamped to the girder plate unit 3, according to the scale line 96 corresponding to the slider 91 on the previous adjusting device 9, the slider 91 on the next adjusting device 9 is adjusted to the corresponding scale, so that the sliders 91 on the two adjusting devices 9 are in the same plane. Thus, after the next adjusting device 9 is moved to the girder plate unit 3, the slider 91 on the next adjusting device 9 can be directly clamped to the transverse stiffener 1 of the girder plate unit 3 without further adjusting the position of the slider 91 on the next adjusting device 9, so as to improve the use efficiency of the adjusting device 9.

[0079] Optionally, as combined with Figure 19 shown, the adjusting device 9 further includes a locking device 11, and the locking device 11 is used to fixedly connect the slider 91 with the first cross beam 94.

[0080] Specifically, the locking device 11 can be a locking bolt. After the slider 91 is clamped to the corresponding transverse stiffener 1, the locking bolt is tightened, and the locking bolt abuts against the first cross beam 94 to limit the sliding of the slider 91, so as to ensure the stability of the clamping of the slider 91 to the corresponding transverse stiffener 1. Similarly, the sliding of the slider 91 on the second cross beam 94 can also be limited by the locking bolt abutting against the second cross beam 95. In this way, the locking device 11 can ensure the use stability of the slider 91.

[0081] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will all fall within the protection scope of the present invention.
