Description

Technical Field

[0001] The invention relates to the technical field of hoisting construction, in particular to a chain hoisting safety handrail installation. Background Art

[0002] In the process of sorting marine parts, chain suction code lifting is a common way of handling parts. Usually, when lifting parts by magnetic suction code, the operator needs to hold the chain and place the suction code on the part to be lifted so that the suction code can be adsorbed on the part through its own magnetism. However, in actual operation, there are two major problems with the current operation method: First, due to the operator's barehanded operation, the operator and the chain are at most an arm's length away. Due to the close distance between the operator, it is very likely that the lifted parts will fall accidentally due to problems such as weak magnetic suction or lifting misoperation, causing safety accidents, threatening the life safety of the operator. Moreover, when the size of the part to be lifted is large, it is difficult to place the magnetic suction code at the center of gravity of the part, and the operation is difficult, which not only affects the operation efficiency, but also further increases the risk of parts falling. Second, the chain itself is not easy to grasp, and the barehanded grasping method is prone to chain ring squeezing the hand, which will also threaten the operator's personal health. Summary of the invention

[0003] In view of the above problems existing in the prior art, an embodiment of the present invention provides a chain lifting safety handrail installation to solve the technical problems existing in the prior art that chain suction code lifting is difficult and prone to injuries.

[0024] It should also be understood that, although the present application has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present application that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0025] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0026] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to determine the true intent based on the user's historical operations and to avoid unnecessary or redundant details that make the present application unclear. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but are merely used as the basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0027] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments are only used to explain the present invention and are not used to limit the scope of the present invention. Figure 1 , the preferred embodiments of the present invention are further described in detail:

[0029] like Figure 1 As shown, an embodiment of the present invention provides a chain hoisting safety handrail device, comprising:

[0030] A connecting sleeve 1, a connecting arm 3 and a handrail 4, wherein the connecting sleeve 1 is sleeved and fixed on the chain, the connecting arm 3 is fixedly arranged on the connecting sleeve 1, and a handrail 4 is fixedly arranged on the outer end thereof;

[0031] Among them, the fixing method of the connecting sleeve 1 on the chain can be selected according to actual needs, taking into account factors such as operational convenience and difficulty in obtaining materials. In one embodiment, the connecting sleeve 1 is fixed to the chain in a detachable manner by connecting bolts. The detachable connection method of the connecting bolts can, on the one hand, reduce the difficulty of installation and simplify the installation operation process while ensuring a firm connection. On the other hand, the setting height of the handrail 4 can be adjusted according to the height adaptability of different operators. Moreover, the tooling can also be used in a turnover manner according to actual needs. Under the premise of bolting and fixing, in order to ensure the reliability of the connection, the At least two groups of bolt holes 2 for inserting connecting bolts are correspondingly provided on the connecting sleeve 1, and the connecting bolts inserted in each group of bolt holes 2 are located in different chain links of the chain. The method of bolting and fixing with at least two groups of connecting bolts can, on the one hand, avoid the problem of the tool falling off the chain due to the failure of one group of connecting bolts, and on the other hand, reduce the sliding distance of the tool on the chain (if only one group of connecting bolts is provided, the handrail 4 will have a sliding distance of one chain link on the chain), avoid the problem of the handrail tilting down or upturning, and make the tool stuck on the chain and kept in a horizontal state as much as possible for easy holding;

[0032] As described in the background technology section, since the operator operates with bare hands, the operator is at most an arm's length away from the chain. Since the distance is too close, it is very likely that the hoisted parts will accidentally fall due to problems such as weak magnetic suction or misoperation of the hoisting, causing a safety accident, threatening the life of the operator. In addition, when the part to be hoisted is large in size, it is difficult to place the magnetic suction code at the center of gravity of the part, and the operation is difficult, which not only affects the operation efficiency, but also further increases the risk of parts falling. In order to avoid this problem, in one embodiment, the length of the connecting arm 3 is fixed, and the operator holds the handrail 4 with his toes on the tiptoe. Located outside the projection range of the component to be hoisted, at this time, the tooling needs to reasonably select the size according to the parts to be hoisted to avoid the above-mentioned hidden dangers. Of course, the connection form between the connecting arm 3 and the connecting sleeve 1 and the handrail 4 can also be changed to a detachable and fixed form such as bolting, and then the connecting arm 3 of a suitable length can be replaced for operation under different working conditions. In another embodiment, in order to improve the versatility of the tooling, the connecting arm 3 is a telescopic arm with adjustable length, wherein the specific structural form of the telescopic arm should be comprehensively considered according to the on-site material conditions or procurement cost, procurement difficulty and other factors, such as using a spring buckle similar to an umbrella handle;

[0033] When lifting parts, due to the different placement of materials at the stacking site, the phase angle of the operator standing relative to the chain may be different. In order to conveniently hold the handrail 4 at all angles, in one embodiment, the handrail 4 is designed as a circular ring structure, and its inner ring is fixedly connected to the connecting sleeve 1 through a plurality of spaced connecting arms 3. At the same time, the number of the connecting arms 3 should not be less than three to ensure the stability and balance of the handrail 4. The disc-shaped handrail 4 is designed with full consideration of ergonomic principles, which is not only convenient for operators to grasp, making operators more comfortable and stable when grasping, but also can effectively disperse the impact force during the lifting process, reducing the difficulty and danger of operation. In order to further improve the comfort of grasping the handrail and consider the anti-slip problem, the handrail 4 is also provided with an anti-slip rubber sleeve, and the surface of the anti-slip rubber sleeve can be provided with anti-slip patterns such as convex points, stripes, and patterns to avoid the problem of difficulty in holding when the operator has sweat on his hands;

[0034] In one embodiment, the connecting sleeve 1, the connecting arm 3 and the handrail 4 are made of high-strength marine steel, and the structure is strong and durable. At the same time, anti-corrosion coatings such as anti-rust paint can be coated on the connecting sleeve 1, the connecting arm 3 and the handrail 4 to improve the durability and turnover rate of the tooling.

[0035] The embodiment of the present invention uses connecting bolts and chains to fix and adjust the installation height. The design of the tooling fully considers the ergonomic principles, making the operator more comfortable and stable when grasping. The embodiment of the present invention has the following beneficial effects:

[0036] 1. Safety distance guarantee: by rationally designing the structure and size of the tooling, the embodiment of the present invention effectively ensures the safety distance between the operator and the hoisted parts, avoiding safety accidents caused by too close distance;

[0037] 2. Disc-shaped tooling handrail 4. In order to further improve the convenience and safety of grasping, the embodiment of the present invention is provided with a disc-shaped handrail 4, which is not only convenient for operators to grasp, but also can effectively disperse the impact force during the lifting process, reducing the difficulty and danger of operation;

[0038] 3. During the actual cutting and lifting process, the use of tooling makes the operation more convenient and efficient, effectively improving the overall efficiency of the lifting work.

[0039] Next, the economic benefits of the actual application stage are analyzed as follows:

[0040] Project 1: Reduce losses caused by safety accidents

[0041] Background: When lifting parts, safety accidents are likely to occur due to people being too close or the chain being difficult to grasp, resulting in personal injury and property loss.

[0042] Cost savings: By introducing the chain hoisting safety handrail tooling, such safety accidents can be effectively avoided. Assuming that the average annual medical expenses, compensation costs and downtime losses caused by safety accidents total 30,000 yuan, this part of the cost can be saved every year by introducing the tooling.

[0043] Project 2: Benefits from improving work efficiency

[0044] Background: The original lifting method is inconvenient to operate and has low work efficiency compared to the use of tooling.

[0045] Cost savings / benefits: The design of the tooling makes the operation more convenient and improves work efficiency. Assuming that the work efficiency is improved by 5%, the annual increase in output or the saved working hours will bring a benefit of 80,000 yuan (this value needs to be estimated and adjusted according to the actual project situation).

[0046] Estimated annual savings / benefits:

[0047] Project 1: Reduce losses caused by safety accidents = 30,000 yuan / year

[0048] Project 2: Benefits from improved work efficiency = 80,000 yuan / year

[0049] Total economic benefits:

[0050] Total annual savings / revenue = 30,000 yuan + 80,000 yuan = 110,000 yuan / year

[0051] In summary, the chain hoisting safety handrail assembly proposed in the embodiment of the present invention has significant economic benefits, and can save a total of 110,000 yuan in costs / revenues each year. This not only improves the safety of hoisting operations, but also improves work efficiency, providing strong technical support for the inherent safety and efficiency of industrial production.
