Description

Technical Field

[0001] The utility model relates to the technical field of roller backstops, in particular to a directional transmission anti-reverse device applied to a slag conveyor belt. Background Technique

[0002] A roller backstop is a braking device for a belt conveyor. It is installed separately on the shaft extension of the low-speed shaft of the reducer to brake the driving roller when parking, which can prevent the reverse rotation or smooth sliding phenomenon of the inclined belt conveyor when parking with load.

[0003] When the roller backstop is put into use, it needs to be sleeved on the driving roller of the belt conveyor first, and then the roller backstop is fixed on the frame of the belt conveyor by bolts.

[0004] However, the models and sizes of belt conveyors are different. When the roller backstop needs to be installed on the frame, it is necessary to measure the position of the mounting holes on the roller backstop first, and then corresponding mounting holes are opened on the frame of the belt conveyor for installation. However, manual measurement is inevitably prone to errors. If the deviation of the measurement is too large, the roller backstop cannot be installed, and it is necessary to re-drill holes, which is not very convenient to use. Content of the Utility Model

[0005] The purpose of the utility model is to provide a directional transmission anti-reverse device applied to a slag conveyor belt to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A directional transmission anti-reverse device applied to a slag conveyor belt, including a roller backstop. A chute is opened on the roller backstop, and an adjusting mechanism for convenient installation is arranged on the roller backstop. By setting the adjusting mechanism, the distance between two mounting holes can be adjusted, which is convenient for installing the roller backstop. An auxiliary mechanism is arranged on the adjusting mechanism. By setting the auxiliary mechanism, the roller backstop can be installed with bolts of different sizes, greatly improving the practicability of the roller backstop. The adjusting mechanism includes:

[0007] A slider, which is slidably connected to the inner wall of the chute. Mounting holes are opened on the slider, and an L-shaped rod is fixedly installed on the side wall of the slider;

[0008] A sliding plate, which is slidably connected to the inner wall of the roller backstop. An inclined groove is opened on the sliding plate, and the end of the L-shaped rod away from the slider fits against the inner wall of the inclined groove. By setting the inclined groove, the L-shaped rod can be extruded;

[0009] A threaded rod, one end of which is rotatably connected to the inner wall of the roller backstop, the other end of the threaded rod is fixedly installed with a knob, and the outer wall of the threaded rod is threadedly connected to the inner wall of the sliding plate.

[0010] Preferably, the auxiliary mechanism includes a positioning plate which is slidably connected to the inner wall of the slider.

[0011] Preferably, four groups of positioning holes are formed in the positioning plate, and the apertures of the four groups of positioning holes are all different. By providing four groups of positioning holes with different apertures, the roller check valve can be installed using bolts of different sizes.

[0012] Preferably, four groups of limiting holes are formed in the L-shaped rod, and the distance between adjacent two groups of limiting holes is equal to the distance between adjacent two groups of positioning holes.

[0013] Preferably, a ball plunger is slidably connected to the inner wall of the positioning plate. By providing the ball plunger in cooperation with the limiting holes, the positioning plate can be limited.

[0014] Preferably, one end of the ball plunger is attached to the inner wall of the limiting hole, and a spring is fixedly installed at the other end of the ball plunger.

Specific embodiments

[0024] As Figures 1-5 shown, the present utility model provides a technical solution: a directional transmission anti-reverse device applied to a slag conveyor belt, including a roller check valve 1, a chute 2 is provided on the roller check valve 1, and an adjusting mechanism 3 convenient for installation is provided on the roller check valve 1. By setting the adjusting mechanism 3, the distance between two groups of sliders 31 can be adjusted, so that the distance between two mounting holes 34 can be adjusted, which is convenient for installing the roller check valve 1. An auxiliary mechanism 4 is provided on the adjusting mechanism 3. By setting the auxiliary mechanism 4, the roller check valve 1 can be installed using bolts of different sizes, greatly improving the practicability of the roller check valve 1.

[0025] The above-mentioned adjusting mechanism 3 includes a slider 31, a slide plate 32, a threaded rod 33, a mounting hole 34, an L-shaped rod 35, an inclined groove 36, and a knob 37; the slider 31 is slidably connected to the inner wall of the chute 2, a mounting hole 34 is provided on the slider 31, an L-shaped rod 35 is fixedly installed on the side wall of the slider 31, the slide plate 32 is slidably connected to the inner wall of the roller check valve 1, and an inclined groove 36 is provided on the slide plate 32. By using two groups of inclined grooves 36 with opposite orientations on the slide plate 32 in cooperation with the L-shaped rod 35, two groups of sliders 31 can slide synchronously in opposite directions and move away from each other, so that the distance between the mounting holes 34 on the two groups of sliders 31 can be adjusted, which is convenient for adjusting according to the holes on the belt conveyor frame. One end of the L-shaped rod 35 away from the slider 31 fits against the inner wall of the inclined groove 36. When the slide plate 32 slides downward, at this time the inclined groove 36 will squeeze the L-shaped rod 35, so that the L-shaped rod 35 drives the slider 31 to slide on the inner wall of the chute 2. One end of the threaded rod 33 is rotatably connected to the inner wall of the roller check valve 1, the other end of the threaded rod 33 is fixedly installed with a knob 37, and the outer wall of the threaded rod 33 is threadedly connected to the inner wall of the slide plate 32. By rotating the knob 37 to rotate the threaded rod 33, the slide plate 32 threadedly connected thereto can be driven to slide up and down on the inner wall of the roller check valve 1.

[0026] The above-mentioned auxiliary mechanism 4 includes a positioning plate 41, positioning holes 42, limiting holes 43, a ball plunger 44, and a spring 45; the positioning plate 41 is slidably connected to the inner wall of the slider 31, and four groups of positioning holes 42 are formed in the positioning plate 41. The diameters of the four groups of positioning holes 42 are all different. By providing four groups of positioning holes 42 with different diameters, bolts of different sizes can be used to install the roller check valve 1. Four groups of limiting holes 43 are formed in the L-shaped rod 35, and the distance between adjacent two groups of limiting holes 43 is equal to the distance between adjacent two groups of positioning holes 42. A ball plunger 44 is slidably connected to the inner wall of the positioning plate 41. One end of the ball plunger 44 abuts against the inner wall of the limiting hole 43, and a spring 45 is fixedly installed at the other end of the ball plunger 44. The end of the spring 45 away from the ball plunger 44 is fixedly installed on the inner wall of the positioning plate 41. The elasticity of the spring 45 can be used to push the ball plunger 44 into the interior of the limiting hole 43. By using the ball plunger 44 in cooperation with the limiting hole 43, the positioning plate 41 can be limited, so that the positioning hole 42 and the mounting hole 34 maintain a stable concentric state.

[0027] Working principle: Pass the bolt through the mounting hole 34 and the hole on the belt conveyor frame, and then install the nut on the bolt. The roller check valve 1 can be fixed on the belt conveyor frame by using the nut and the bolt. When there is an error between the hole on the belt conveyor frame and the mounting hole 34, rotate the threaded rod 33 through the knob 37. The rotation of the threaded rod 33 can drive the slide plate 32 threadedly connected thereto to slide up and down on the inner wall of the roller check valve 1. When the slide plate 32 slides downward, the inclined groove 36 will squeeze the L-shaped rod 35 at this time, so that the L-shaped rod 35 drives the slider 31 to slide on the inner wall of the chute 2. At this time, by using the two inclined grooves 36 with opposite orientations on the slide plate 32 in cooperation with the L-shaped rod 35, the two sliders 31 can slide synchronously in opposite directions and move away from each other, so that the distance between the mounting holes 34 on the two sliders 31 can be adjusted, which is convenient for adjustment according to the hole on the belt conveyor frame, and thus convenient for the installation of the roller check valve 1.

[0028] By pushing the positioning plate 41 to slide on the inner wall of the slider 31, at the same time, the positioning plate 41 will drive the ball plunger 44 to move synchronously. During the movement of the ball plunger 44, the ball head surface will be squeezed by the limiting hole 43, so that the ball plunger 44 slides and contracts towards the inside of the positioning plate 41, and at the same time compresses the spring 45, so that the ball plunger 44 can be disengaged from the limiting hole 43, and then the positioning plate 41 can be moved. By moving the positioning plate 41, the positioning hole 42 can be aligned with the mounting hole 34 to keep the positioning hole 42 and the mounting hole 34 concentric. At this time, the elastic force of the spring 45 can be used to push the ball plunger 44 into the inside of the limiting hole 43. The ball plunger 44 and the limiting hole 43 are used to limit the positioning plate 41 to keep the positioning hole 42 and the mounting hole 34 in a stable concentric state. By providing four groups of positioning holes 42 with different hole diameters, the roller check valve 1 can be installed with bolts of different sizes, which greatly improves the practicability of the roller check valve 1.

[0029] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
