DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] With reference to Figures 1-5 , the utility model provides an embodiment:

[0026] The invention discloses a crown block with anti-inclination device, which comprises a crown block body 2 and two slide rails 7, the middle points of the opposite sides of the two slide rails 7 are embedded with auxiliary support mechanisms 3, the upper ends of the two sides of the outer wall of the crown block body 2 are fixedly provided with anti-inclination mechanisms 1, the lower end surface of the crown block body 2 is installed with a hoisting mechanism 5, the front and rear ends of the two sides of the outer wall of the crown block body 2 are fixedly provided with connecting shafts 6, the ends of the four connecting shafts 6 away from the crown block body 2 are fixedly provided with moving rollers 4, the lower ends of the opposite sides of the two slide rails 7 are provided with a first track groove 8, and the two moving rollers 4 located on the same side of the same slide rail 7 are a group, and the two groups of moving rollers 4 are slidably embedded in the two first track grooves 8.

[0027] Specifically, in use, the crown block body 2 can be guided and slid along the two slide rails 7 by the moving rollers 4 installed on the two sides, thereby forming a track type carrying and moving effect, and the hoisting mechanism 5 arranged at the lower end can be used for hoisting and carrying materials.

[0028] With reference to Figures 1-4 , the auxiliary support mechanism 3 comprises an outer plate 303, a plurality of connecting springs 302 are fixedly arranged in the inner portion of the outer plate 303, and the one end of the connecting spring 302 is fixedly provided with an inner plate 301; the inner portion of the outer plate 303 is provided with a movable cavity 304; the one end of the inner plate 301 is arc-shaped and penetrates through the outer wall of the outer plate 303; and the one end of the plurality of connecting springs 302 away from the inner plate 301 is fixedly arranged on one side of the inner wall of the outer plate 303.

[0029] Specifically, when the inner plate 301 is extruded by external force, the inner plate 301 moves to the inner portion of the outer plate 303 and extrudes the connecting spring 302 on the inner side, the connecting spring 302 shrinks after being stressed, and due to the restoring property of the spring itself, an opposite force is generated, thereby achieving the effect of buffering and auxiliary support.

[0030] With reference to Figures 1-3 and Figure 5 , the anti-inclination mechanism 1 comprises a first connecting block 102, a second connecting block 104 is fixedly arranged on one side of the first connecting block 102, a telescopic spring 106 is fixedly arranged on the side of the second connecting block 104 away from the first connecting block 102, the second connecting block 104 is embedded in the inner portion of the crown block body 2, and an adjusting screw rod 101 is threadedly sleeved on the upper end of the first connecting block 102.

[0031] Specifically, in use, the adjusting screw rod 101 can be rotated to move up and down on the first connecting block 102, the second connecting block 104 is movably embedded in the inner portion of the crown block body 2 and is buffered by the telescopic spring 106, thereby playing the roles of anti-inclination support, auxiliary buffering and traction when the crown block body 2 is inclined.

[0032] With reference to Figures 1-3 and Figure 5The upper surfaces of the two slide rails 7 are provided with second track grooves 9. The lower end of the adjusting screw 101 is fixedly provided with a base 103. The adjusting screw 101 and the base 103 are slidably embedded in the second track grooves 9. The inner sides of the crane body 2 are provided with inner cavities 10. Two second connecting blocks 104 are respectively embedded in the two inner cavities 10. The ends of the two telescopic springs 106 away from the second connecting blocks 104 are fixedly connected to the inner wall of the inner cavity 10. The front and rear ends of the second connecting blocks 104 near the telescopic springs 106 are fixedly provided with protrusions 105.

[0033] Specifically, a base 103 is set at the lower end of the adjusting screw 101 and embedded in the second track groove 9. The base 103 is confined inside to prevent it from derailing and can move up and down with the adjusting screw 101, thereby changing the pressure on the contact surface with the slide rail 7 and changing the friction. The extension spring 106 is set to provide auxiliary support and buffering effect and avoid hard collision breakage of direct rigid connection.

[0034] Reference Figure 1 , Figure 2 The lifting mechanism 5 includes a drive motor 501 and two mounting plates 503. The two mounting plates 503 are respectively fixedly installed at the front and rear ends of the lower end of the crane body 2. The drive motor 501 is fixedly installed on one of the mounting plates 503, and a lifting roller 502 is fixedly installed at the output end of the drive motor 501. The end of the lifting roller 502 away from the drive motor 501 is rotatably mounted on the other mounting plate 503 away from the drive motor 501.

[0035] Specifically, when in use, a steel rope can be wound on the lifting roller 502, and the material to be lifted can be tied to the lower end of the steel rope. When the drive motor 501 starts, it drives the lifting roller 502 to rotate, thereby raising and lowering the height of the material lifted at the lower end. After the material is separated from the ground, it can be moved along the track by the crane body 2.

[0036] Working principle: When in use, the overhead crane can slide along the slide rails 7 on both sides. When the crane body 2 tilts to the side, it first comes into contact with the auxiliary support mechanism 3. After the auxiliary support mechanism 3 is subjected to force, the inner plate 301 contracts, and the internal connecting spring 302 contracts and generates a reverse pushing force, thereby playing an auxiliary support role.

[0037] Secondly, the anti-tilt mechanism 1 located on both sides of the crane body 2 supports the crane body 2. Since the lower end of the anti-tilt mechanism 1 is embedded in the slide rail 7 and its movement direction is restricted, it can only move in the direction of the track groove and will not tilt to the side. Thus, the anti-tilt mechanism 1 on one side supports the side of the crane body 2, while the anti-tilt mechanism 1 on the other side plays an auxiliary pulling effect on the crane body 2.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
