Description

Technical Field

[0001] This utility model relates to the technical field of excavation equipment for water diversion inclined shaft sections, and in particular to a track slide device applied to an inclined shaft excavation trolley. Background Technology

[0002] The track slide device, used in inclined shaft excavation trolleys, ensures smooth operation of the trolley. During inclined shaft excavation, due to the complex working environment and high precision requirements, a device is needed to allow the excavation trolley to move stably and be precisely positioned; the track slide device was developed to address this need. It provides stable movement and precise positioning for the excavation trolley along the guide rails laid along the inclined shaft. Its functions include improving excavation efficiency, reducing trolley movement and adjustment time; enhancing operational flexibility to adapt to construction in different parts of the inclined shaft; ensuring construction quality, guaranteeing excavation dimensional accuracy and reducing errors; and improving construction safety, providing reliable protection for trolley operations.

[0003] In existing technologies, most guide slide platforms used in inclined shaft excavation trolleys encounter problems during use. These problems arise because uneven guide surfaces or external factors such as construction vibrations can cause changes in the angle between the slide platform and the mounting plate. The gap between the slide platform and the guide platform cannot be adaptively adjusted, leading to the slide platform getting stuck during movement. This disrupts the inclined shaft excavation operation, severely impacting the continuity and efficiency of construction. Therefore, to address these shortcomings, a track slide platform device for inclined shaft excavation trolleys is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a track slide device for inclined shaft excavation trolleys, aiming to improve the problem that in some existing guide slide devices used on inclined shaft excavation trolleys, the gap between the slide and the guide track cannot be adaptively changed during use, resulting in jamming and affecting work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A track slide device for an inclined shaft excavation trolley includes a frame. Guide rails are fixedly connected to opposite ends of the top side of the frame. Sliding platforms are slidably connected to the top sides of the two guide rails. Moving components for facilitating the movement of the sliding platforms are hinged to the front ends of the opposite sides of the sliding platforms via upper pins. Lower mounting plates are hinged to the rear ends of the opposite sides of the sliding platforms. Multiple lower support wheels are rotatably connected to the interior of the lower mounting plates via multiple pins. Two upper rubber pads are fixedly connected to the right top side of the sliding platforms. Two lower rubber pads are fixedly connected to the left bottom side of the lower mounting plates. Side rubber pads are fixedly connected to the opposite sides of the two sliding platforms. Upper pins are fixedly connected to the right ends of the opposite sides of the sliding platforms. Lower pins are fixedly connected to the left ends of the opposite sides of the sliding platforms. Two telescopic hydraulic cylinders are fixedly connected inside the guide rails.

[0007] As a further description of the above technical solution:

[0008] The moving component includes an upper mounting plate, and the interiors of two upper mounting plates are hinged to the front ends of the sliding table on opposite sides by upper pins. Multiple upper support wheels are installed inside the upper mounting plates.

[0009] As a further description of the above technical solution:

[0010] The outer sides of the plurality of upper support wheels are respectively rolledly connected to the bottom side of the guide track at a distance from each other, and the outer sides of the plurality of lower support wheels are respectively rolledly connected to the top side of the guide track at a distance from each other.

[0011] As a further description of the above technical solution:

[0012] The drive ends of the two telescopic cylinders are fixedly connected to the outside of the sliding table, and limit plates are fixedly connected to the opposite sides of the two upper pins.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, the upper and lower support wheels are hinged to the sliding table via upper and lower mounting plates, respectively. This allows the sliding table to adjust its angle automatically as it slides on the guide rail. By placing rolling elements on both sides of the hinge point of the mounting plate, the gap between the sliding table and the guide rail changes when the angle between the sliding table and the mounting plate changes. This prevents the sliding table from getting stuck during movement, thereby improving work efficiency and continuity. At the same time, increasing the distance between the upper and lower support rolling elements reduces the pressure between the support wheels and the guide rail surface, preventing damage to the guide rail and support wheels due to stress concentration, and thus extending their service life.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1 to 3 This utility model provides an embodiment of a track slide device for an inclined shaft excavation trolley, comprising a frame 1, which serves as the basic structure of the entire device, providing stable support and installation foundation for subsequent components. Guide rails 2 are fixedly connected to opposite ends of the top side of the frame 1, and are connected to the frame 1 and guide rails 2 by welding to ensure that there is no loosening or displacement between the guide rails 2 and the frame 1. Sliding platforms 3 are slidably connected to the top sides of the two guide rails 2, and the sliding action of the sliding platforms 3 on the guide rails 2 enables the vertical adjustment of the entire inclined shaft excavation trolley. Multiple upper support wheels 5 are respectively rolledly connected to the opposite ends of the bottom side of the guide rails 2 to guide the rotation of the upper support wheels 5 and prevent deviation. The opposite front ends of the sliding platforms 3 are hinged to movable components that facilitate the movement of the sliding platforms 3 via upper pins 11. The hinged connection provides both connection strength and relative rotation within a certain range between the movable components and the sliding platforms 3, thereby adapting to angle changes and position adjustments that occur when the sliding platforms 3 move on the guide rails 2.

[0022] The moving component includes upper mounting plates 4. The interiors of two upper mounting plates 4 are hinged to the distal ends of the sliding table 3 via upper pins 11, creating a flexible connection between the upper mounting plates 4 and the sliding table 3, providing a basis for subsequent motion transmission and angle adjustment. Multiple upper support wheels 5 are installed inside the upper mounting plates 4 to support them and ensure stable sliding. Lower mounting plates 6 are hinged to the distal ends of the sliding table 3, ensuring a stable connection between the sliding table 3 and the lower mounting plates 6 while allowing for relative rotation to a certain extent. Multiple lower support wheels 7 are rotatably connected to the interiors of the lower mounting plates 6 via multiple pins, ensuring stability during rotation and the ability to withstand various forces generated during operation. The exteriors of the multiple lower support wheels 7 are rolled to the distal ends of the top side of the guide rail 2, creating a symmetrical support and rolling arrangement for the sliding table 3 on the guide rail 2.

[0023] Two upper rubber pads 8 are fixedly connected to the top right end of the sliding table 3. These upper rubber pads 8 form a buffer layer between the sliding table 3 and the components it contacts above, preventing rigid collisions and reducing noise and component wear. Two lower rubber pads 9 are fixedly connected to the bottom left end of the lower mounting plate 6, serving the same purpose as the upper rubber pads 8 to absorb the impact generated during operation. Side rubber pads 10 are fixedly connected to the opposite sides of both sliding tables 3. These side rubber pads 10 effectively absorb these lateral forces, preventing lateral displacement and damage to the sliding tables 3. Upper pins 11 are fixedly connected to the right end of the opposite sides of both sliding tables 3. Limit plates are fixedly connected to the opposite sides of both upper pins 11 to limit the distance the sliding tables 3 travel during movement, ensuring a safe range of movement on the guide rail 2. Lower pins 12 are fixedly connected to the left end of the opposite sides of both sliding tables 3, serving the same purpose as the upper pins 11. Two telescopic hydraulic cylinders 13 are fixedly connected inside the guide channel 2 to fix the lower pin 12, so that the lower pin 12 can stably provide power. The drive ends of the two telescopic hydraulic cylinders 13 are fixedly connected to the outside of the sliding table 3. The sliding table 3 absorbs the thrust of the drive ends of the telescopic hydraulic cylinders 13, and then drives the telescopic hydraulic cylinders 13 to slide.

[0024] Working Principle: The hydraulic system providing power to the telescopic cylinder 13 is activated, bringing the system to its normal working pressure. According to the inclined shaft excavation work plan, the sliding platform 3 is moved to its initial working position by operating the control device of the telescopic cylinder 13. During the inclined shaft excavation process, based on the excavation depth, angle, and other operational requirements, the upper support wheel 5 and lower support wheel 7 roll on the guide rail 2. The upper mounting plate 4 and lower mounting plate 6 automatically adapt to the angle changes of the sliding platform 3 through their hinged structure, ensuring smooth movement of the sliding platform 3. Simultaneously, the upper rubber pad 8, lower rubber pad 9, and side rubber pad 10 on the sliding platform 3 continuously provide cushioning, reducing vibration and impact. When it is necessary to pause the work, the operation of the telescopic cylinder 13 is stopped, allowing the sliding platform 3 to remain in its current position.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
