Description

Technical Field

[0001] This utility model relates to the field of mining lifting technology, specifically to a mechanical support platform for mining. Background Technology

[0002] Installing heavy-duty main pipelines for water supply, compressed air, and drainage in the roof of major underground mine roadways presents numerous challenges. The large diameter and weight of the pipes result in a large workload, high labor intensity, and significant construction difficulty. The traditional method involves using hand-operated hoists to lift and install the pipelines, but this requires pre-installation of lifting anchor bolts, a cumbersome process that severely restricts construction efficiency. Furthermore, the pipelines need to be aligned during installation, which is difficult after lifting. In addition, on-site construction poses serious safety hazards, hindering safe production underground.

[0003] Existing technologies already include designs for related support platforms, such as the patent with publication number CN220618291U. These platforms use an electric push rod to drive the first rod to move to one side and unfold the articulated telescopic frame. The first rod slides within a limiting groove, thereby limiting the upward movement of the lifting frame and allowing for adjustment of the equipment's lifting height. At the same time, pressure blocks prevent the equipment from tipping over, ensuring the stability of the equipment. This eliminates the need for manual operation or lifting, reducing labor intensity and improving equipment efficiency.

[0004] However, the above-mentioned device still has drawbacks: when heavy main pipelines are placed on it, the platform is prone to sinking due to insufficient ground bearing capacity because the bottom contact surface is small, resulting in unstable support and affecting the normal operation and safety of mining machinery. Utility Model Content

[0021] like Figure 1-5 As shown, this utility model includes a base 1, with rotating plates 3 rotatably connected to the front and rear sides of the base 1. A set of transmission components 5 is provided on the base 1 corresponding to each rotating plate 3, used to unfold or retract the rotating plates 3. By setting the transmission components 5, after the platform moves to the working position, the two rotating plates 3 can be unfolded, increasing the contact area between the bottom of the platform and the ground, preventing safety hazards such as ground subsidence, improving the support stability of the platform lifting, and increasing the working efficiency of the support platform.

[0022] It also includes a substrate 20, the top of which is provided with an alignment component for assisting in the alignment and installation of the pipeline, and the top of the alignment component is provided with a fixing component 11 for clamping the pipeline.

[0023] The base plate 20 has four vertically mounted columns at its bottom corners, and the base 1 is fixed to the base plate 20 by these four columns. A moving assembly 6 is provided between the base 1 and the base plate 20. The moving assembly 6 includes a sliding plate 18, which is slidably connected to the four columns. Support rods are vertically mounted at the four bottom corners of the sliding plate 18, and each of the four support rods has a caster wheel 19 at its bottom. Openings are provided on the base 1 at the positions corresponding to the caster wheels 19, allowing the caster wheels 19 to pass through the base 1. By adding the moving assembly 6, the caster wheels 19 can be lifted off the ground during the unfolding of the rotating plate 3 by the transmission assembly 5, preventing accidental movement of the platform and improving the safety of the lifting operation.

[0024] The transmission assembly 5 includes a motor 2, which is fixed above the center of the base 1. A first gear 12 is located at the bottom of the motor 2, and the output end of the motor 2 is connected to the first gear 12.

A second gear 14 is provided at the end of each second threaded rod 13 near the motor 2, and the two second gears 14 mesh with the first gear 12 respectively. A sliding strip 15 is threaded onto each of the second threaded rods 13, and a rotating square rod 16 is rotatably connected to both ends of each sliding strip 15. The end of each rotating square rod 16 is rotatably connected to its corresponding rotating plate 3.

[0025] The top of the motor 2 is provided with a first threaded rod 4, the output end of the motor 2 is connected to the first threaded rod 4, and the first threaded rod 4 is threadedly connected to the sliding plate 18.

[0026] Each of the second threaded rods 13 is further provided with a first guide rod 17 on its left and right sides, and the first guide rods 17 are all fixed on the base 1. Each of the first guide rods 17 is of the same length as its corresponding second threaded rod 13 and is aligned with it.

[0027] The alignment assembly includes two L-shaped fixing plates 8 arranged on the left and right sides. The right-angle ends of each fixing plate 8 are close together, and the short sides of each fixing plate 8 point downwards. The long sides of each fixing plate 8 are horizontal and hollow inside, with the right-angle ends of each long side open and the far right-angle ends closed. A horizontal plate 10 is fitted inside each fixing plate 8, with its two sides inserted into the long sides of the two fixing plates 8 respectively. The horizontal plate 10 is slidably connected to the two fixing plates 8. A limiting plate is vertically positioned downwards at the bottom center of the horizontal plate 10, located between the short sides of the two fixing plates 8. A second hydraulic cylinder 9 is horizontally mounted on the short side of the left fixing plate 8, and the second hydraulic cylinder 9 is fixed through and fixed to the limiting plate.

[0028] Two first hydraulic cylinders 7 are respectively provided on the outer side of the short side of each fixed sleeve plate 8. The output end of each first hydraulic cylinder 7 is fixedly connected to the bottom of the corresponding fixed sleeve plate 8. Each first hydraulic cylinder 7 passes through the base plate 20 and the sliding plate 18 in sequence and is fixed thereto.

[0029] The alignment assembly also includes a second guide rod 21, which extends laterally through the short sides and limiting plates of the two fixed sleeve plates 8. There are two second guide rods 21, arranged parallel to each other along the short sides and limiting plates of the two fixed sleeve plates 8. By setting up the alignment assembly, the platform can be lifted as a whole and then finely adjusted in the left and right directions, facilitating alignment during the installation of heavy-duty main pipelines.

[0030] The horizontal plate 10 has two vertically arranged support plates of equal height on its front and rear sides. The fixing assembly 11 includes a horizontally arranged fixing frame 22. The tops of the two support plates are fixed to the front and rear sides of the bottom center of the fixing frame 22, respectively. Two clamping blocks 24 are slidably arranged in the left and right directions on the top of the fixing frame 22. A double-ended threaded rod 23 is horizontally inserted through the bottom of the fixing frame 22. The bottoms of each clamping block 24 are threaded to the left and right sides of the double-ended threaded rod 23, respectively.

[0031] Both ends of the double-ended threaded rod 23 extend out of the fixing frame 22 and are respectively equipped with handwheels 25.

[0032] The fixed frame 22 is provided with two sliding grooves at the front and back. Each clamping block 24 passes through the two sliding grooves on both the front and back sides and is slidably connected to the fixed frame 22.

[0033] The fixing component 11 also includes a third guide rod 26, which extends laterally through the bottom of the two clamping blocks 24 and the fixing frame 22. There are two third guide rods 26, arranged parallel to each other at the bottom of the two clamping blocks 24 and the fixing frame 22.

[0034] The method of using the mining mechanical support platform described in this utility model is as follows: By cranking the two handwheels 25, the distance between the two clamping blocks 24 is adjusted, and the heavy-duty main pipeline is placed between the two clamping blocks 24, so that it is clamped by the clamping blocks 24. The original state of this device is: the sliding plate 18 is located at the bottom end of the first threaded rod 4, the four casters 19 are in contact with the ground, and the base 1 is away from the ground.

[0035] This device is connected to the vehicle body, thereby propelling it to the target location. Once the target location is reached, the device is detached from the vehicle body.

[0036] When the motor 2 is started, the first threaded rod 4 rotates, causing the sliding plate 18 to slide upward along the column. The sliding plate 18 drives the four support rods to move upward synchronously, and the overall height of the device begins to decrease until the caster wheel 19 passes through the base 1 upward, at which point the base 1 contacts the ground, the overall height of the device stops decreasing, and the moving component 6 is completely moved between the base 1 and the base plate 20.

[0037] At the same time, after the motor 2 is started, the first gear 12 begins to rotate, and the two second gears 14 also begin to rotate, driving their respective corresponding second threaded rods 13 to rotate, which in turn drives their corresponding sliding bars 15 to move outward on the second threaded rods 13. The sliding bars 15 drive the rotating square rod 16 to move outward synchronously, thereby flipping and unfolding the rotating plate 3 on the corresponding side outward.

[0038] The two actions mentioned above are performed simultaneously. When the base 1 contacts the ground, the two rotating plates 3 also complete the unfolding action. At this time, the stop motor 2 is turned on.

[0039] By activating the first hydraulic cylinder 7, the base plate 20 is raised to a suitable height. By activating the second hydraulic cylinder 9, the horizontal plate 10 can be stably moved slightly left and right between the two fixed sleeve plates 8, thereby facilitating the alignment and installation of the pipeline. By turning the handwheel 25, the pipeline can be released from between the two clamping blocks 24.

[0040] After the pipeline installation is completed, when the device needs to be retrieved, simply retract the first hydraulic cylinder 7 and start the motor 2 in reverse so that all actions are reversed: the rotating plate 3 is retrieved to the left and right sides of the base 1, and the casters 19 return to their extended positions under the base 1. This completes the retrieval of the device.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
