Description

Technical Field

[0001] The utility model relates to the technical field of coal mine support, in particular to a movable support platform. Background Art

[0002] In coal mining, the main tunnels used to transport coal glue (coal binder) in coal mines are very important to support the side of the coal glue transportation tunnels because heavy equipment and a large amount of materials are involved in the transportation of coal glue. The support operation aims to strengthen the surrounding rock of the coal mine tunnels to prevent accidents such as rock collapse and roof collapse, while ensuring the safety and smooth transportation of coal glue. However, the local height of the underground mine is 3.8-4.4 meters, and the existing support drilling rigs cannot meet the construction requirements. In addition, there are belt conveyors in the glue transportation tunnels, so the ordinary support platform set up inside will be inconvenient to move. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a movable support platform, which solves the problem that ordinary support platforms inside the mine are inconvenient to move.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a movable support platform, including a support frame, and a movable structure is symmetrically arranged on the surface of the support frame.

[0005] The movable structure includes a connecting plate and a fixed plate, the bottom of the connecting plate is slidably sleeved with a gripping rod through a spring, the top of the connecting plate is rotatably sleeved with a rotating part, and the rotating part is slidably sleeved with a mounting plate through a sliding groove, the surface of the fixed plate is fixedly connected to a motor, and the output end of the motor is fixedly connected to an eccentric wheel, the surface of the eccentric wheel is rotatably sleeved with a connecting rod, and one end of the connecting rod is rotatably sleeved on the connecting plate.

[0006] Preferably, a protective frame is symmetrically fixedly connected to the top of the support frame.

[0007] Preferably, the fixing plate is fixedly sleeved on the lower end of the supporting frame, and the mounting plate is fixedly connected to the supporting frame and the protective frame.

[0008] Preferably, universal wheels are provided at four corners of the support frame.

[0009] Preferably, a grid plate is provided on the top of the support frame.

[0010] Preferably, the lower end of the support frame is symmetrically fixedly connected with reinforcing ribs.

[0011] The utility model provides a movable support platform. Compared with the prior art, it has the following beneficial effects:

[0012] 1. The movable support platform drives the eccentric wheel to rotate through the output end of the motor, thereby driving the connecting rod to perform eccentric movement, and directly driving the connecting plate to move freely following the eccentric movement. At the same time, the upper end of the connecting plate slides in the inner cavity of the slide groove through the rotating part, so the upper end of the connecting plate can rotate and slide. When the eccentric wheel rotates to the lowest point, it will drive the gripping rod at the bottom of the connecting rod to contact the ground and generate gripping force, thereby pulling the support frame forward through the universal wheel.

[0013] 2. When the movable support platform is gripping the ground, the spring can drive the gripping rod to retract into the inner cavity of the connecting rod while gripping the ground, so as to ensure that the support frame will not be lifted when the support frame is driven to move.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1The utility model provides a technical solution: a movable support platform, including a support frame 1, a mobile structure 2 is symmetrically arranged on the surface of the support frame 1, a protective frame 4 is symmetrically fixedly connected to the top of the support frame 1, universal wheels 6 are arranged at the four corners of the support frame 1, a grid plate 3 is arranged on the top of the support frame 1, and reinforcing ribs 5 are symmetrically fixedly connected to the lower end of the support frame 1, wherein the reinforcing ribs 5 form steps to facilitate the staff to go up and down, and a part is extended at both ends of the protective frame 4 to serve as a handrail, wherein when the support frame 1 is moving, the foot brake on the universal wheel 6 is released, moved to the required position, and then the foot brake is locked.

[0022] See also Figure 2-5 The mobile structure 2 includes a connecting plate 21 and a fixed plate 23, the fixed plate 23 is fixedly sleeved on the lower end of the support frame 1, the bottom of the connecting plate 21 is slidably sleeved with a gripping rod 27 through a spring 210, the top of the connecting plate 21 is rotatably sleeved with a rotating member 28, and the rotating member 28 is slidably sleeved with a mounting plate 22 through a slide groove 29, and the mounting plate 22 is fixedly connected to the support frame 1 and the protective frame 4, the surface of the fixed plate 23 is fixedly connected with a motor 24, and the output end of the motor 24 is fixedly connected with an eccentric wheel 25, the surface of the eccentric wheel 25 is rotatably sleeved with a connecting rod 26, and one end of the connecting rod 26 is rotatably sleeved on the connecting plate 21, wherein a concave-convex layer is provided at the bottom of the gripping rod 27 to increase friction with the ground.

[0023] When working or using, first place the support frame 1 in the well. Since the middle of the support frame 1 is hollow, the belt conveyor in the well is located in the hollow position of the support frame 1, and the universal wheels 6 on the left and right of the support frame 1 are on both sides. When the work needs to move, start the motor 24 on the fixed plate 23, so that the output end of the motor 24 drives the eccentric wheel 25 to rotate, thereby driving the connecting rod 26 to perform eccentric movement, and directly driving the connecting plate 21 to follow the eccentric movement to move freely. At the same time, the upper end of the connecting plate 21 slides in the inner cavity of the slide groove 29 through the rotating member 28, so the upper end of the connecting plate 21 can rotate and slide. When the eccentric wheel 2 When the eccentric wheel 25 rotates to the lowest point, the gripping rod 27 at the bottom of the connecting rod 26 will be driven to contact the ground and generate gripping force, thereby pulling the support frame 1 forward through the universal wheel 6. At the same time, when gripping the ground, the gripping rod 27 can be driven by the spring 210 to retract in the inner cavity of the connecting rod 26 while gripping the ground, so as to ensure that the support frame 1 will not be lifted when the support frame 1 is driven to move. Then, when the eccentric wheel 25 rotates to the highest point, the gripping rod 27 at the bottom of the connecting rod 26 will be driven to leave the ground. At the same time, the spring 210 will drive the gripping rod 27 to reset, and then to the lowest point to grip the ground and pull the support frame 1 to move, and the cycle can be continued to move.
