Problems solved by technology
Moreover, existing lifting pulleys often have broken accidents during work, especially high-altitude operations, which are likely to cause personal accidents to workers below, and the existing lifting pulley structure is cast molding, which not only has trachoma pores, but also has slag inclusions. , cracks and high-cost defects
[0003] This shows that above-mentioned existing hoisting pulley obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem

Embodiment Construction
[0020] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, characteristics and features of a lifting pulley proposed according to the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments. Efficacy, detailed as follows.
[0021] see Figure 1 to Figure 5 , The lifting pulley of the present invention includes: a stressed pulley 2, a web 3, a reinforcing rib 4, and a central insertion tube 5. Wherein, the outer peripheral edge of the web 3 is affixed to the inside of the force-bearing pulley 2, the central cannula 5 penetrates and is affixed to the center of the web 3, and the ribs 4 are uniformly welded to the front and back of the web 3 respectively, and strengthen One end of the rib 4 is welded with the periphery of the central cannula 5, and the other end is welded with the stressed pulley 2, a...

The invention relates to a hoisting pulley. The hoisting pulley comprises a force pulley, a web plate, reinforcing ribs and a center insertion pipe; the outer peripheral edge of the web plate is fixedly connected into the force pulley; the center insertion pipe penetrates and is fixedly connected with the center of the web plate; the reinforcing ribs are uniformly and fixedly connected with the front and back side of the web plate; one end of every reinforcing rib is fixedly connected with the outer periphery of the center insertion pipe; the other end of every reinforcing rib is fixedly connected with the force pulley; the hoisting pulley is formed by Q235-A steel plates; the force pulley is formed through intermediate frequency cutting in a one-step mode and the opening angle of the force pulley is 40 to 45 degrees. The hoisting pulley has the advantages of being high in strength, safe, reliable and economical.
Description
technical field [0001] The invention relates to lifting equipment, in particular to a lifting pulley for the lifting equipment. Background technique [0002] The lifting pulley is traditionally made of HT150-200 or QT420 casting. During the casting process, there are many casting defects of sand holes and holes, which seriously affect the mechanical performance of the pulley. When collided, squeezed, inclined, etc., it is easy to cause edge chipping. Moreover, existing lifting pulleys often have broken accidents during work, especially high-altitude operations, which are likely to cause personal accidents to workers below, and the existing lifting pulley structure is cast molding, which not only has trachoma pores, but also has slag inclusions. , cracks and high-cost defects. [0003] This shows that above-mentioned existing lifting pulley obviously still has inconvenience and defect in structure and use, and demands urgently further improving. In order to solve the above...
