Description

Technical Field

[0001] This utility model relates to the field of busbar cable tray technology, and more specifically to a cable tray that is easy to level. Background Technology

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of various industries has increased rapidly. In particular, with the emergence of numerous high-rise buildings and large factory workshops, the traditional high-current transmission system of cables can no longer meet the requirements. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Busbar trays, a new type of power distribution conductor, have emerged. Compared with traditional cables, they fully demonstrate their superiority in high-current transmission. At the same time, due to the adoption of new technologies and processes, the contact resistance and temperature rise at the connection points of the two ends of the busbar tray and the insertion points of the branch ports have been greatly reduced, and they have been widely used.

[0003] Insufficient technology: During the construction of busbar cable trays, support frames are required at some special locations. To ensure stability, the support frames are usually fixed by bolts through pre-drilled holes in the ground. However, during fixing, the support frames are prone to deviations in height and angle, thus failing to provide adequate support for the busbar cable trays. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cable tray that is easy to level, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable tray that is easy to level, including a base mechanism, and further including: a first lifting mechanism, an adjusting mechanism, a support frame, and a second lifting mechanism. The inner side wall of the base mechanism is movably connected to the side of the adjusting mechanism. The bottom end of the first lifting mechanism is movably connected to the top end of the adjusting mechanism by a pin. The bottom end of the second lifting mechanism is fixedly connected to the top end of the adjusting mechanism. The top end of the first lifting mechanism is movably connected to the bottom end of the support frame by a pin. The top end of the second lifting mechanism is movably connected to the bottom end of the support frame by a pin. The base mechanism includes a base body, and a through hole is provided at the top end of the base body.

[0006] Furthermore, the structure of the first lifting mechanism is the same as that of the second lifting mechanism. The first lifting mechanism includes a column, a first threaded rod is movably sleeved on the inner wall of the bottom end of the column, a telescopic column is movably threaded to the side of the first threaded rod, the top end of the telescopic column is movably connected to the inner wall of the side of the column, the side of the telescopic column is provided with a scale, and the top end of the telescopic column is movably connected to the bottom end of the support frame by a pin.

[0007] Furthermore, a first worm gear is movably sleeved on the inner side wall of the column, and a first worm wheel is fixedly sleeved on the side of the first threaded rod, with the side of the first worm wheel meshing with the side of the first worm gear.

[0008] Furthermore, the adjustment mechanism includes a mounting plate, a sliding groove is provided at the top of the base body, the side of the sliding groove is movably connected to the side of the mounting plate, a second threaded rod is movably sleeved on the side of the sliding groove, the side of the second threaded rod is threadedly connected to the inner wall of the side of the mounting plate, the top of the mounting plate is movably connected to the bottom of the column by a pin, and the bottom of the second lifting mechanism is fixedly connected to the top of the mounting plate.

[0009] Furthermore, the base body has an internal cavity, and a second worm gear is movably sleeved at the bottom end of the cavity. A second hexagonal groove is provided at the top end of the second worm gear, and a second worm wheel is fixedly sleeved on the side of the second threaded rod. The side of the second worm wheel meshes with the side of the second worm gear.

[0010] Furthermore, a rotating handle is movably connected to the side of the first worm gear, and a first hexagonal locking block is fixedly connected to the side of the rotating handle.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model adjusts the support frame in the lateral direction through an adjustment mechanism, and simultaneously adjusts the first lifting mechanism and the second lifting mechanism to raise and lower the support frame to a suitable height. At the same time, according to the usage requirements, the first lifting mechanism or the second lifting mechanism can be adjusted separately to make the support frame rotate along the top pins of the first lifting mechanism and the second lifting mechanism, so that the support frame keeps the support frame horizontal and supports the busbar cable tray, which helps to ensure that the busbar cable tray remains horizontal.

[0013] 2. This utility model inserts the first hexagonal locking block at the end of the rotating handle into the first hexagonal locking groove. Rotating the rotating handle causes the first worm to rotate through the meshing of the first hexagonal locking block and the first hexagonal locking groove.

The threaded rod then drives the telescopic column to move up and down along the inner side wall of the column. After adjustment, the rotating handle can be removed. The operation is simple and helps to improve work efficiency. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The leveling cable tray involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figures 1 to 5 This utility model provides a cable tray that is easy to level, including a base mechanism 1, and further including: a first lifting mechanism 2, an adjusting mechanism 3, a support frame 4, and a second lifting mechanism 5. The inner side wall of the base mechanism 1 is movably connected to the side of the adjusting mechanism 3. The bottom end of the first lifting mechanism 2 is movably connected to the top end of the adjusting mechanism 3 by a pin. The bottom end of the second lifting mechanism 5 is fixedly connected to the top end of the adjusting mechanism 3. The top end of the first lifting mechanism 2 is movably connected to the bottom end of the support frame 4 by a pin. The top end of the second lifting mechanism 5 is movably connected to the bottom end of the support frame 4 by a pin. The base mechanism 1 includes... The system includes a base body 101, with a through hole 103 at the top. The equipment is placed in a suitable position, and bolts are passed through the through hole 103 for fixation. According to usage requirements, the support frame 4 is adjusted in the lateral direction by the adjustment mechanism 3. At the same time, the first lifting mechanism 2 and the second lifting mechanism 5 are adjusted to raise and lower the support frame 4 to a suitable height. Also, according to usage requirements, the first lifting mechanism 2 or the second lifting mechanism 5 can be adjusted individually to make the support frame 4 rotate along the top pins of the first lifting mechanism 2 and the second lifting mechanism 5, so that the support frame 4 remains horizontal and supports the busbar cable tray.

[0022] The structure of the first lifting mechanism 2 is the same as that of the second lifting mechanism 5. The first lifting mechanism 2 includes a column 201. A first threaded rod 207 is movably sleeved on the inner wall of the bottom end of the column 201. A telescopic column 202 is movably threaded to the side of the first threaded rod 207. The top of the telescopic column 202 is movably connected to the inner wall of the side of the column 201. The side of the telescopic column 202 is provided with a scale. The top of the telescopic column 202 is movably connected to the bottom end of the support frame 4 through a pin. The rotation of the first threaded rod 207 drives the telescopic column 202 to move up and down along the inner wall of the side of the column 201 through the thread. Similarly, the second lifting mechanism 5 is adjusted to adjust the height and angle of the support frame 4.

[0023] The first worm gear 204 is movably sleeved on the inner side wall of the column 201, and the first worm wheel 208 is fixedly sleeved on the side of the first threaded rod 207. The side of the first worm wheel 208 meshes with the side of the first worm gear 204. The rotation of the first worm gear 204 drives the rotation of the first threaded rod 207 through the meshing of the first worm gear 204 and the first worm wheel 208. At the same time, the first worm gear 204 can drive the first worm wheel 208 to rotate. The characteristic that the first worm wheel 208 cannot drive the first worm gear 204 to rotate fixes the first lifting mechanism 2.

[0024] The adjustment mechanism 3 includes a mounting plate 301. A groove 102 is provided at the top of the base body 101. The side of the groove 102 is movably connected to the side of the mounting plate 301. A second threaded rod 302 is movably sleeved on the side of the groove 102. The side of the second threaded rod 302 is threadedly connected to the inner wall of the side of the mounting plate 301. The top of the mounting plate 301 is movably connected to the bottom of the column 201 by a pin. The bottom of the second lifting mechanism 5 is fixedly connected to the top of the mounting plate 301. The rotation of the second threaded rod 302 drives the mounting plate 301 to move along the groove 102 through the thread, thereby adjusting the position of the support frame 4 in the lateral direction.

[0025] The base body 101 has a cavity 104 inside. A second worm 303 is movably sleeved at the bottom end of the cavity 104. A second hexagonal groove 304 is formed at the top end of the second worm 303. A second worm wheel 305 is fixedly sleeved on the side of the second threaded rod 302. The side of the second worm wheel 305 meshes with the side of the second worm 303. When the second worm 303 rotates, the second threaded rod 302 is driven to rotate through the meshing of the second worm 303 and the second worm wheel 305.

[0026] The first worm gear 204 is movably connected to a handle 203 on its side. A first hexagonal locking block 206 is fixedly connected to the side of the handle 203. A first hexagonal slot 205 is formed on the side of the first worm gear 204. The side of the first hexagonal slot 205 and the side of the first hexagonal locking block 206 mesh with each other. The specifications of the first hexagonal slot 205 are the same as those of the second hexagonal slot 304. The first hexagonal locking block 206 at the end of the handle 203 is inserted into the first hexagonal slot 205. Rotating the handle 203 causes the first worm gear 204 to rotate through the meshing of the first hexagonal locking block 206 and the first hexagonal slot 205. After adjustment, the handle 203 is removed. Similarly, the first hexagonal locking block 206 at the end of the handle 203 is inserted into the second hexagonal slot 304 to adjust the adjustment mechanism 3.

[0027] The working principle of this utility model is as follows: The equipment is placed in a suitable position, and bolts are passed through the through hole 103 for fixation. The first hexagonal locking block 206 at the end of the rotating handle 203 is inserted into the first hexagonal locking groove 205. Rotating the rotating handle 203 causes the first worm gear 204 to rotate through the meshing of the first hexagonal locking block 206 and the first hexagonal locking groove 205. The first worm gear 204, in turn, meshes with the first worm wheel 208, causing the first threaded rod 207 to rotate. This threaded rod drives the telescopic column 202 to move up and down along the inner side wall of the column 201. Similarly, the second lifting mechanism 5 is adjusted to regulate the height of the support frame 4. Simultaneously, depending on the usage requirements, the first lifting mechanism 2 or the second lifting mechanism 5 can be adjusted individually to make the support frame 4 rotate along the top pins of the first lifting mechanism 2 and the second lifting mechanism 5, so that the support frame 4 remains horizontal to support the busbar bridge. Then, the handle 203 is removed, and the first hexagonal locking block 206 at the end of the handle 203 is inserted into the second hexagonal locking groove 304, which drives the second worm 303 to rotate. Through the meshing of the second worm 303 and the second worm wheel 305, the second threaded rod 302 is driven to rotate. Through the thread, the mounting plate 301 is moved along the slide groove 102, thereby adjusting the position of the support frame 4 in the lateral direction.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
