Description

Technical Field

[0001] The utility model belongs to the technical field of material suction overhead cranes, and in particular relates to a material suction overhead crane with an environmentally friendly material suction pipe. Background Art

[0002] During the operation of the suction overhead crane, not only will dust-containing airflow be generated inside the silo, but also dust will be generated flying in the air. This is because the end of the suction pipe has a poor fit with the material surface, which will form an airflow escape channel on the contact surface, causing dust to overflow into the environment with the airflow. In addition, the negative pressure environment of the suction system is weakened due to the existence of gaps, resulting in the dust being unable to be effectively sucked into the pipeline. Instead, a local dust zone is formed around the suction port.

[0003] In the prior art, a Chinese utility model patent document with authorization announcement number CN219216884U discloses a secondary dust removal system for a suction overhead crane, which absorbs dust generated at the suction pipe by setting an annular pipe at the outer end of the suction pipe and providing a dust suction pipe opening on the annular pipe, but it cannot reduce the generation of dust.

[0004] Therefore, it is necessary to design a suction overhead crane with an environmentally friendly suction pipe that can improve the fit between the bottom end of the suction pipe and the material and reduce dust escape to solve the current technical problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a suction overhead crane with an environmentally friendly suction pipe, which can improve the fit between the bottom end of the suction pipe and the material and reduce dust escape.

[0006] The technical solution of the utility model is: a suction crane with an environmentally friendly suction pipe, comprising a suction crane body and a suction pipe arranged on the suction crane body, the bottom end of the suction pipe is fixedly connected with a flexible pipe, the bottom end of the flexible pipe is connected with a rigid suction cover, the four sides of the suction cover are connected to the side of the suction pipe through a floating suspension mechanism; the floating suspension mechanism has a universal joint fixedly arranged on the side of the suction pipe, a connecting seat is fixedly arranged on the universal joint, a slide cylinder is fixedly arranged on the connecting seat, a pull rod is slidably arranged inside the end of the slide cylinder away from the universal joint, and the end of the pull rod away from the slide cylinder is hinged to the suction cover.

[0007] Furthermore, a slider is slidably arranged inside the slide cylinder, one end of the pull rod away from the suction cover is fixedly connected to the slider, and one end of the slide cylinder away from the suction pipe is provided with a stop edge corresponding to the slider.

[0008] Furthermore, a return spring is arranged between one end of the slide cylinder close to the suction pipe and the slider.

[0009] Furthermore, a hinged joint is fixedly provided on one end of the pull rod away from the slide cylinder, a hinge seat corresponding to the hinged joint is fixedly provided on the outer side of the suction hood, and the hinged joint is hinged to the hinge seat.

[0010] Furthermore, a flexible cover is fixedly provided on the outer side of the material suction cover, and the flexible cover is detachably fixedly connected to the material suction cover.

[0011] Furthermore, a pressure ring is arranged on the outer side of the upper end of the flexible cover, and bolt and nut mechanisms for detachably and fixedly connecting the pressure ring with the suction cover are evenly arranged on the pressure ring.

[0012] Furthermore, the flexible cover is a conical cover structure made of silicone or rubber material.

[0013] Beneficial effects of the utility model:

[0014] (1) In the present invention, the suction pipe and the suction hood are connected by a flexible pipe. When the suction hood contacts the top of the material, as the suction pipe moves downward, the angle can be changed according to the slope of the top of the material, so that the bottom of the suction hood is in full contact with the top of the material, the gap is reduced, the dust escape is reduced, and the dust can be effectively sucked into the suction pipe along with the material;

[0015] (2) The suction hood is connected to the suction pipe through a floating suspension mechanism, which can reduce the axial force of the flexible pipe and ensure its normal service life. At the same time, it does not affect the adjustment of the suction hood to fit the slope of the top of the material. BRIEF DESCRIPTION OF THE DRAWINGS

The floating suspension mechanism 3 has a universal joint 31 fixedly provided on the side surface of the material suction pipe 1. A connecting seat 32 is fixedly provided on the universal joint 31. A sliding cylinder 33 is fixedly provided on the connecting seat 32. A pull rod 37 is slidably arranged inside the end of the sliding cylinder 33 away from the universal joint 31. One end of the pull rod 37 away from the sliding cylinder 33 is hinged to the material suction hood 2. The material suction pipe 1 and the material suction hood 2 are connected through the flexible pipe 4. When the material suction hood 2 comes into contact with the top of the material, as the material suction pipe 1 moves downward, the angle can be changed along with the slope of the top of the material, so that the bottom of the material suction hood 2 is in full contact with the top of the material, reducing the gap and reducing the escape of dust, enabling the dust to be effectively sucked into the material suction pipe along with the material; the periphery of the material suction hood 2 is connected to the material suction pipe 1 through the floating suspension mechanism 3, which can reduce the axial force on the flexible pipe 4, ensure its normal service life, and at the same time does not affect the adjustment of the material suction hood 2 to fit the slope of the top of the material.

[0022] In some embodiments, four floating suspension structures 3 are arranged in a circular array between the material suction hood 2 and the material suction pipe 1.

[0024] In some embodiments, a return spring 36 is arranged between one end of the slide cylinder 33 close to the suction pipe 1 and the slider 35; when the suction hood 2 fits the slope of the top of the material, the slider 35 slides inside the slide cylinder 33, and the return spring 36 is compressed. The elastic force of the return spring 36 acts on the slider 35, so that the suction hood 2 can fit the top of the material, thereby achieving the purpose of reducing the gap.

[0025] In some embodiments, as a specific connection method between the pull rod 37 and the suction hood 2, a hinge joint 39 is fixedly provided on the end of the pull rod 37 facing away from the slide cylinder 33, and a hinge seat 38 corresponding to the hinge joint 39 is fixedly provided on the outer side of the suction hood 2, and the hinge joint 39 is hinged to the hinge seat 38.

[0026] In some embodiments, a flexible cover 5 is fixedly provided on the outside of the suction hood 2, and the flexible cover 5 is detachably fixedly connected to the suction hood 2; the flexible cover 5 can adaptively fit the surface shape of the material, further reduce the suction gap, and reduce dust emission; the flexible cover 5 is detachable and can be disassembled and replaced if it is damaged.

[0027] In some embodiments, a pressure ring 6 is provided on the outer side of the upper end of the flexible cover 5, and bolt and nut mechanisms are evenly provided on the pressure ring 6 for detachably fixing the pressure ring 6 with the suction cover 2. A through hole for the bolt and nut mechanism is opened on the flexible cover 5.
