The longitudinal keel (4) consists of two or more keels of equal length, arranged at intervals along the transverse direction. The transverse keel (5) consists of two keels, which are fixedly connected to both ends of the longitudinal keel (4). The two ends of the cable tray keel (3) are fixedly connected to the mounting wall (10) and the fixing wall (11) of the shaft, respectively. The construction platform is located on a row of cable tray keels (3) at a height of 1.8 to 2.0 meters above the ground, and the longitudinal keel (4) of the construction platform is fixedly connected to the row of cable tray keels (3). The cable shaft construction platform provided by this utility model is composed of longitudinal and transverse keel frames, which are set at certain heights inside the shaft. Workers stand on the construction platform to lay cables, which is convenient and labor-saving, greatly reducing labor intensity, improving labor efficiency, and ensuring safe production. Moreover, the construction platform can continue to be used during the use and maintenance of the shaft, thus improving the utilization rate of the construction platform.

[0004] The existing technology has the following technical problems: the existing platform for cable tray construction in vertical shafts is not convenient for confining the cage, and its stability and safety need to be improved; therefore, we propose a platform for cable tray construction in vertical shafts to solve the problems mentioned above. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] To address the technical problems of existing platforms used for cable tray construction in vertical shafts being inconvenient for securing the hoisting cage, and the need to improve stability and safety, this embodiment discloses the following technical solution:

[0032] Please see Figure 1 - Figure 6 A platform for constructing cable trays in a vertical shaft includes a limiting platform 1, a first limiting structure 2, a double-headed motor 201, a lead screw 202, a moving rod 203, a limiting block 204, a sliding structure 3, a sliding groove 301, a slider 302, a connecting block 303, a second limiting structure 4, an L-shaped connecting rod 401, a limiting plate 402, and a cage 5.

[0033] like Figure 1 - Figure 4 As shown, the front and rear ends of the platform 1 are provided with sliding structures 3. The sliding structure 3 includes a sliding groove 301, a slider 302 and a connecting block 303. The sliding groove 301 is opened in the front wall and the rear wall of the platform 1. One end of the slider 302 is fixedly connected to the connecting block 303. The slider 302 is slidably connected in the sliding groove 301, so that the connecting block 303 is slidably connected to the platform 1.

[0034] like Figure 1 - Figure 5 As shown, the sliding structure 3 is connected to the second limiting structure 4 by screws. The second limiting structure 4 includes an L-shaped connecting rod 401 and a limiting plate 402. The vertical bar of the L-shaped connecting rod 401 is fixedly connected to the limiting plate 402, and the horizontal bar of the L-shaped connecting rod 401 is fixedly connected to the connecting block 303 by screws. The screws make it easy to separate the L-shaped connecting rod 401 and the connecting block 303, thereby making it easy to separate the sliding structure 3 and the second limiting structure 4, and thus making it easy to replace the limiting plate 402.

[0035] The slider 302 drives the limiting plate 402 to slide left and right, thereby facilitating the adjustment of the position of the limiting plate 402 and enabling the device to adapt to wells of different widths;

[0036] like Figure 4 and Figure 5 As shown, a first limiting structure 2 is installed inside the limiting platform 1. The first limiting structure 2 includes a dual-head motor 201, a lead screw 202, a moving rod 203, and a limiting block 204. The dual-head motor 201 is fixedly installed inside the limiting platform 1, the lead screw 202 is rotatably connected inside the limiting platform 1, and the limiting block 204 is slidably connected inside the limiting platform 1.

[0037] A cage 5 is fixedly installed at the top of the platform 1. The cage 5 is lifted and moved by a hoist (not shown). After the cage 5 reaches the position, a double-headed motor 201 is driven by a controller (not shown). The output ends of the double-headed motor 201 are fixedly connected to lead screws 202, and the threads of the lead screws 202 at both ends of the double-headed motor 201 are opposite. The double-headed motor 201 drives the lead screws 202 at both ends to rotate in the same direction. The threads of the lead screws 202 at both ends drive the moving rods 203. The rotating lead screws 202 drive the moving rods 203 at the left and right ends to move away from each other. The moving rods 203 are fixedly connected to limiting blocks 204. The moving rods 203 at the left and right ends drive the limiting blocks 204 at both ends to move away from each other, so that the limiting blocks 204 at the left and right ends move closer to the limiting plate 402.

[0038] As the limiting plate 402 approaches, the limiting block 204 continues to move, bringing the limiting plate 402 closer to the well wall and pressing the outer wall of the limiting plate 402 tightly against the well wall. At this time, the limiting block 204 presses tightly against the limiting plate 402, fixing the limiting platform 1 in any position inside the well, thus facilitating the fixing of the cage 5 in any position inside the well. Each side is provided with two limiting blocks 204, one above the other. This design allows the upper and lower ends of the limiting plate 402 to fit tightly against the well wall. Using the limiting plate 402 to contact the well wall increases the contact area, greatly improving stability and installation performance. At the same time, the side of the limiting plate 402 that contacts the well wall is made of a relatively rough material, or the surface is ground rough, increasing the friction between it and the well wall, further improving stability and safety.

[0039] After the operation is completed, the controller drives the double-headed motor 201 in reverse and the lead screw 202 rotates in reverse, so that the limiting blocks 204 at the left and right ends move closer to each other and the limiting blocks 204 move away from the limiting plate 402, thereby canceling the thrust of the limiting plate 402 on the well wall, thus making it easier to continue moving the cage 5.

[0040] During the movement, since the limiting plate 402 is still in contact with the outer wall, it may rub against the well wall. Prolonged friction will reduce the service life of the limiting plate 402. Therefore, the limiting plate 402 and the limiting block 204 can be made of magnetic materials, that is, the limiting plate 402 and the limiting block 204 can attract each other (such as the limiting plate 402 and the limiting block 204 are respectively embedded with opposite magnetic attractants), so that the limiting plate 402 can move with the limiting block 204, thereby completely separating from the well wall and avoiding prolonged friction.

[0041] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
