Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an adjustable sliding track. Background Art

[0002] During the construction of large-scale tube trusses, there are often problems such as the impact of other objects in the construction area or insufficient working surface. Under this specific construction condition, the tube truss steel structure usually adopts a single-piece assembly and cumulative sliding construction method. The sliding construction process has high requirements on the stability, safety and synchronization of the two ends of the tube truss. The selection of the sliding beam structure plays a vital role in ensuring the smooth progress of the tube truss sliding construction.

[0003] At present, the commonly used sliding methods in China are fixed-step hydraulic jacking sliding and hydraulic crawling jacking sliding. The tracks of these two sliding methods use channel steel + lateral baffle + jacking device, and I-beam + clamping device respectively. The two methods are relatively mature in technology, but there are still some shortcomings: the width of the sliding groove inside the sliding track is limited and cannot be adjusted. When the width of the sliding part is large, it is necessary to replace the larger track, which increases the cost of use. When the width of the sliding part is narrow, there will be a large gap between the baffles on both sides of the track, and it is easy to roll over during the sliding process, which requires the staff to readjust, which is time-consuming and labor-intensive, and reduces work efficiency. In this regard, we propose an adjustable sliding track. Utility Model Content

[0025] Example

[0026] Reference Figures 1 to 5The present embodiment provides an adjustable sliding track, including a sliding mechanism 100 and an adjusting mechanism 200. The sliding mechanism 100 includes a web 101, and side baffles 102 are symmetrically installed on the left and right sides of the web 101. Through grooves 101a are symmetrically opened on the left and right sides of the web 101. A limiting plate 103 is slidably connected in the through groove 101a. A mounting frame 104 is fixedly installed in the middle of the bottom end of the web 101. The bottom end of the limiting plate 103 passes through the through groove 101a and extends to the bottom of the web 101. The upper part of the limiting plate 103 is slidably connected to the web. 101, so that a sliding groove S is formed above the two limit plates 103 and the web 101, the sliding member can move in the sliding groove S, and the distance between the two limit plates 103 can be adjusted by the adjustment mechanism 200, so that sliding members of different sizes can be used on the sliding track. Compared with the traditional sliding track, the problem of frequent track replacement is solved, the cost of use is reduced, and the sliding track can adjust the gap between the limit plate 103 and the sliding member, ensuring the stability of the sliding member when moving and improving work efficiency.

[0027] Specifically, the adjustment mechanism 200 includes a servo motor 201 fixedly installed at the front end of the mounting frame 104, the output end of the servo motor 201 is connected to the rotating shaft 202 through a coupling transmission, the rear end of the rotating shaft 202 penetrates the outer wall of the mounting frame 104 and extends to the inside thereof and is fixedly connected to an active conical tooth 203, the left and right sides of the active conical tooth 203 are meshedly connected to driven conical teeth 204, the other ends of the two driven conical teeth 204 are fixedly connected to a rotating rod 205, the other ends of the two rotating rods 205 are fixedly connected to a threaded rod 206, the outer surfaces of the two threaded rods 206 are threadedly connected to telescopic sleeves 207, and the opposite ends of the two telescopic sleeves 207 penetrate the inner wall of the mounting frame 104 and extend to the outside thereof and are respectively fixed to the side walls of the two limit plates 103.

[0028] In the adjustment mechanism 200, the servo motor 201 is a prior art specific structure and will not be described in detail. When the staff turns on the servo motor 201, the servo motor 201 can drive the rotating shaft 202 to rotate, the rotating shaft 202 can drive the active conical gear 203 to rotate, the active conical gear 203 can drive the two driven conical gears 204 to rotate in the opposite direction, and the two driven conical gears 204 can drive the two threaded rods 206 to rotate in the opposite direction through the two rotating rods 205, and the telescopic sleeves 207 threadedly connected to the two threaded rods 206 can move horizontally in opposite directions, and the two The telescopic sleeve 207 can drive the two limit plates 103 to move horizontally in opposite directions, and the distance between the two limit plates 103 can be expanded, so that the sliding width in the sliding groove S can be increased. Similarly, when the servo motor 201 drives the rotating shaft 202 and the active conical gear 203 to rotate in the opposite direction, the two telescopic sleeves 207 can move horizontally relative to each other, thereby driving the two limit plates 103 to move closer to each other, so that the sliding width in the sliding groove S can be reduced. Through the setting of the above structure, the function of adjusting the distance between the two limit plates 103 is realized.

[0029] Furthermore, a cavity 104a is provided in the middle of the mounting frame 104, and the active conical gear 203 and the two driven conical gears 204 are both arranged in the cavity 104a. The cavity 104a provides sufficient space for the operation of the active conical gear 203 and the two driven conical gears 204, and telescopic cavities 104b are symmetrically provided on the left and right sides of the cavity 104a, and the telescopic sleeve 207 and most of the threaded rod 206 are both arranged in the telescopic cavity 104b, and the telescopic sleeve 207 is close to the rotating rod 206. A square block 208 is fixedly installed at one end of 05, and the square block 208 is slidably connected in the telescopic cavity 104b. The telescopic cavity 104b is set to provide space for the telescopic sleeve 207 to move horizontally inside the installation frame 104. The square block 208 can limit the telescopic sleeve 207, which can prevent the telescopic sleeve 207 from being separated from the telescopic cavity 104b when moving, and can also prevent the telescopic sleeve 207 from rotating with the threaded rod 206 when rotating, thereby preventing the telescopic sleeve 207 from rotating horizontally.

[0030] Preferably, a bearing 209 is fixedly installed at the connection between the rotating shaft 202 and the inner wall of the mounting frame 104. The rotating shaft 202 is rotatably connected to the inner wall of the mounting frame 104 through the bearing 209. The setting of the bearing 209 can limit and fix the rotating shaft 202. At the same time, due to the characteristics of the bearing 209 itself, the rotating shaft 202 can rotate more smoothly to avoid jamming and affect the normal operation of the adjustment mechanism 200.

[0031] Preferably, a limit rod 105 is fixedly installed inside the through slot 101a, and the limit plate 103 is slidably sleeved on the limit rod 105. The limit rod 105 can not only provide a limit support for the limit plate 103, but also ensure that the limit plate 103 moves horizontally more smoothly.
