A spiral hoist chain plate and a spiral hoist having the same

Abstract

The embodiment of the present invention discloses a spiral elevator chain plate and a spiral elevator having the same. The spiral elevator chain plate comprises a chain plate body. One or more ball mounting holes are arranged on the chain plate body. Balls are rotatably mounted in the ball mounting holes respectively. The balls are arranged obliquely along the conveying direction of the spiral elevator. The conveyed articles enter the spiral elevator through the rotation of the balls and the action of the spiral elevator chain plate. When the conveyed articles enter the spiral elevator from the side entrance midway, the front half of the conveyed articles is supported on the balls. The obliquely arranged balls give the conveyed articles a force deviating toward the center direction of the spiral elevator. The force deviating toward the center direction of the spiral elevator forms a dynamic transition together with the force conveyed by the spiral elevator chain plate, driving the conveyed articles to move closer to the inner side of the spiral elevator, helping the conveyed articles to enter the spiral elevator and avoid being stuck at the entrance.

Technical Field

[0001] The embodiments of the present invention relate to the technical field of conveying equipment, and in particular to a spiral elevator chain plate and a spiral elevator having the same. Background Art

[0002] When the spiral elevator is feeding sideways, the conveyed items enter from the side of the entrance of the spiral elevator. The force direction of the conveyed items is different from the output direction of the force of the spiral elevator conveying chain plate. Only part of the conveyed items touches the spiral elevator chain plate. The forward conveying force of the spiral elevator chain plate is not enough to drive the conveyed items forward, resulting in the conveyed items being unable to enter the spiral elevator smoothly and being stuck at the entrance. Summary of the invention

[0003] To this end, an embodiment of the present invention provides a spiral elevator chain plate to solve the problem in the prior art that the forward conveying force of the elevator chain plate is insufficient to drive the conveyed items forward, resulting in the conveyed items being unable to smoothly enter the spiral elevator and being stuck at the entrance.

[0004] In order to achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0005] According to a first aspect of an embodiment of the present invention, a spiral elevator chain plate is provided, comprising a chain plate body, wherein the chain plate body is provided with one or more ball mounting holes, balls are rotatably mounted in the ball mounting holes, and the balls are inclined along the conveying direction of the spiral elevator, and the conveyed items enter the spiral elevator through the rotation of the balls and the action of the spiral elevator chain plate.

[0006] Furthermore, it also includes a fixed shaft, both ends of which are fixed in the ball mounting hole, and the ball is rotatably arranged on the fixed shaft.

[0007] Furthermore, the angle between the axial direction of the fixed shaft and the conveying direction of the screw elevator is an acute angle.

[0008] Furthermore, when there are multiple ball mounting holes, the multiple ball mounting holes are arranged in one row or multiple rows along the length direction of the spiral elevator chain plate.

[0009] Further, when the ball mounting holes are arranged in one row or multiple rows, the spacing between two adjacent ball mounting holes is the same or different.

[0010] Furthermore, the ball is made of plastic.

[0011] Furthermore, the circumference and inner end of the ball are both provided with rubber coating.

[0023] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] According to a first aspect of an embodiment of the present invention, a spiral hoist chain plate is provided, such as Figure 1 As shown, it includes a chain plate body 1, and one or more ball mounting holes 2 are arranged on the chain plate body 1. Balls 4 are rotatably mounted in the ball mounting holes 2, and the balls 4 are inclined along the conveying direction of the screw elevator. Through the rotation of the balls 4 and the action of the screw elevator chain plate 10, the conveyed items enter the screw elevator.

[0025] In the embodiment of the present invention, one or more ball mounting holes 2 are provided on the chain plate body 1, wherein a ball 4 is rotatably installed in each ball mounting hole 2, and the ball 4 is inclined along the conveying direction of the spiral elevator. When the conveyed items enter the spiral elevator from the side entrance midway, the front half of the conveyed items is supported on the ball 4, and the inclined ball 4 gives the conveyed items a force biased toward the center direction of the spiral elevator. The force biased toward the center direction of the spiral elevator forms a dynamic transition together with the force conveyed by the spiral elevator chain plate 10, driving the conveyed items to move closer to the inner side of the spiral elevator, helping the conveyed items to enter the spiral elevator and avoid being stuck at the entrance.

[0026] In some optional embodiments, the spiral hoist chain plate 10 is a buckle-type chain plate, that is, a single chain plate is buckled on a metal chain.

[0027] In some optional embodiments, a fixed shaft 3 is further included, both ends of the fixed shaft 3 are fixed in the ball mounting hole 2, and the ball 4 is rotatably disposed on the fixed shaft 3.

[0028] By providing the fixed shaft 3 , the balls 4 can rotate around the fixed shaft 3 .

[0029] In some optional embodiments, the angle between the axial direction of the fixed shaft 3 and the conveying direction of the screw elevator is an acute angle.

[0030] Among them, the ball 4 is arranged obliquely outward along the conveying direction of the screw elevator, and the arrow direction below the chain plate body 1 is the conveying direction of the screw elevator, so that the ball 4 can give the conveyed items a force f biased toward the center direction of the screw elevator. The force f biased toward the center direction of the screw elevator and the force of the screw elevator chain plate 10 conveying forward form a dynamic transition, driving the conveyed items to move closer to the inside of the screw elevator, helping the conveyed items to enter the screw elevator without getting stuck at the entrance. In this way, the conveying of items at the side entrance of the screw elevator will not cause traffic jams, causing the conveyed items to press the screw elevator chain plate 10, and the single screw elevator chain plate 10 will not break due to excessive force of the screw elevator rotation.

[0031] In some optional embodiments, when the number of the ball mounting holes 2 is multiple, the multiple ball mounting holes 2 are arranged in one row or multiple rows along the length direction of the spiral elevator chain plate 10.

[0032] By providing a plurality of ball mounting holes 2, the plurality of balls 4 can exert a greater force on the conveyed articles, so that the conveyed articles can enter the spiral elevator chain plate 10 more quickly.

[0033] In some optional embodiments, when the ball mounting holes 2 are arranged in one row or multiple rows, the spacing between two adjacent ball mounting holes 2 is the same or different.

[0034] Among them, the ball mounting hole 2 is Figure 1 When the width of the spiral elevator chain plate 10 is wider, it can also be set as multiple rows of ball mounting holes 2, such as two rows or three rows, wherein the multiple rows of ball mounting holes 2 are arranged in parallel.

[0035] In some optional embodiments, the ball 4 is made of plastic.

[0036] In some optional embodiments, such as Figure 2 As shown, the circumference and inner end of the ball 4 are both provided with rubber coating 5 .

[0037] When the conveyed object is conveyed upward, the outer end a of the ball 4 is close to the side wall of the ball mounting hole 2. The outer end a of the ball 4 is made of plastic and is not covered with rubber, so the friction is small and the conveyed material can be pushed to move obliquely upward; the rubber coating 5 of the circumference of the ball 4 and the inner end b of the ball 4 can increase the friction between the conveyed object and the conveyed object to prevent the conveyed object from sliding downward.

[0038] When the conveyed objects slide downward, the inner end b of the ball 4 is pressed against the side wall of the ball mounting hole 2 under the force of the conveyed objects. The inner end b of the ball 4 is provided with a rubber bag 5, and the friction between the inner end b of the ball 4 and the inner wall of the ball mounting hole 2 is relatively large, thereby playing a role of preventing the conveyed objects from sliding down in the reverse direction on the screw elevator.

[0039] In some optional embodiments, the rubber bag 5 is made of thermoplastic rubber material, which has the advantages of being environmentally friendly, non-toxic and safe, having a wide range of hardness, having excellent colorability, soft touch, weather resistance, fatigue resistance and temperature resistance, having excellent processing performance, and requiring no vulcanization.

[0040] In some optional embodiments, the plurality of fixed shafts 3 may be arranged parallel to each other or non-parallel to each other, as long as the balls 4 can provide a force biased toward the center direction of the spiral elevator to the conveyed objects.

[0041] According to a second aspect of an embodiment of the present invention, there is provided a spiral hoist, such as Figure 3 As shown, it includes a support column 7 and a base 8, wherein the support column 7 is arranged on the base 8, and also includes the spiral elevator chain plate 10 mentioned above.

[0042] In some optional embodiments, guardrails are further included, and the guardrails are arranged at both ends of part of the spiral elevator chain plates 10.

[0043] By providing a guardrail, the conveyed articles can be prevented from falling from the spiral elevator chain plate 10 during the spiral ascent or descent.

[0044] In some optional embodiments, the guardrail includes an inner guardrail 6 and an outer guardrail 9, wherein the inner guardrail 6 is arranged at the inner end of the spiral elevator chain plate 10, and the outer guardrail 9 is arranged at the outer end of the spiral elevator chain plate 10, and the outer guardrail 9 is arranged on a portion of the spiral elevator chain plate 10, wherein a lateral entrance is arranged between the outer guardrails 9 so that the conveyed items can enter laterally.

[0045] exist Figure 1 In the figure, the arrow direction on the left side of the chain plate body 1 is the lateral feeding direction of the conveyed items. The angle between the setting angle of the ball 4 and the feeding direction is 100-140°, such as 135°. Of course, it can also be adjusted according to the actual conveying width of different screw elevators and the size of the conveyed items.

[0046] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
