Description

Technical Field

[0001] This utility model relates to the field of plate chain elevator technology, specifically a protective structure for plate chain elevators to prevent failure and fall. Background Technology

[0002] A plate chain elevator is a high-strength industrial equipment that uses sturdy metal plates as load-bearing components and is pulled by chains to continuously transport large quantities of bulk materials (such as ore, cement, coal, grain, etc.) in a vertical or steeply inclined direction. When dealing with some granular materials, protective devices are required to reduce the possibility of materials falling from the side.

[0003] In the prior art, Chinese Patent Application No. CN202321967156.8 discloses a cement batching chain plate elevator, which relates to the technical field of chain plate elevators. It includes a casing with a discharge pipe and a feed pipe; a conveyor chain disposed within the casing and vertically connected to multiple partitions; an air jet pipe passing through the discharge pipe, with multiple first nozzles vertically facing the conveyor chain on its circumferential sidewall; the air jet pipe is located below the top of the conveyor chain and parallel to the load-bearing surface of the conveyor chain; the air jet pipe also has multiple second nozzles, which are vertically upwards; a protective plate for protecting the air jet pipe is fixedly connected inside the casing; the height of the protective plate gradually decreases along the horizontal direction towards the discharge pipe outlet; and an air pump disposed on the casing, the outlet of which is connected to the air jet pipe via a pipe.

[0004] Based on the above information, it can be seen that the existing plate chain elevator can use a closed structure to achieve the purpose of protection. However, in actual use, the integrated protective mechanism has great limitations, which means that the elevator can only lift materials of a certain size (i.e., the closed structure limits the internal space of the elevator). Utility Model Content

[0005] The purpose of this utility model is to provide a protective structure for a plate chain hoist that prevents failure and falling, so as to solve the problem of the limited use of the protective structure mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for a plate chain hoist to prevent failure and fall, comprising a hoist body and a protective cover installed above the hoist body. The protective cover is divided into a first protective plate and a second protective plate. Fixed magnetic blocks that are magnetically attracted and fixed to the hoist body are fixedly installed on the inner side of the first and second protective plates. An adjustment mechanism for adjusting the distance between the first and second protective plates is provided on the inner side of the protective cover. A dust suction head for adsorbing dust is fixedly installed on the inner side wall of the first protective plate.

[0007] Preferably, the adjustment mechanism includes a limiting block fixedly installed on the inner wall of the first protective plate and the second protective plate, and a guide rod slidably connected to the limiting block is installed through the limiting block.

[0008] Preferably, the limiting block is threaded with a fixing bolt for fixing the guide rod, and the guide rod is provided with uniformly arranged scale marks on its exterior.

[0009] Preferably, a folding cover is fixedly installed between the first protective plate and the second protective plate, and the folding cover is made of a pleated rubber material.

[0010] Preferably, sealing strips are fixedly installed on the sides of the first and second protective plates.

[0011] Preferably, a connecting pipe is fixedly installed on the outer surface of the first protective plate, and the connecting pipe is connected to the vacuum head.

[0012] Preferably, adjacent connecting pipes are connected by a connecting hose, and a mating sleeve is fixedly installed at the top end of the connecting hose, and the mating sleeve is threadedly engaged with the connecting pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the protective structure for the plate chain hoist that prevents failure and falls adopts a novel structural design, the specific details of which are as follows:

[0014] 1. The protective cover is installed on the outside of the elevator body by using the magnetic attraction between the fixed magnetic block and the elevator body. The protective cover protects the material being lifted and prevents the material from falling during the lifting process. The protective cover is designed with a modular structure, and the appropriate number of protective covers can be selected and installed according to the size of the elevator body, thereby improving the overall applicability of the protective cover.

[0015] Furthermore, the protective cover is divided into two parts: a first protective plate and a second protective plate. The first and second protective plates are connected by a folding cover, which allows the first and second protective plates to extend and retract to adjust the distance between them. When adjusting the distance, the limiting block slides relative to the guide rod outside (the limiting block and the guide rod are squeezed to form a certain resistance). The specific distance size can be determined with the help of scale markings, which is convenient for operators to operate.

[0016] 2. A dust suction head is fixedly installed on the inner side of the first protective plate. The dust suction head is connected to an external dust removal device (such as a pump without a dust collector) to achieve the purpose of adsorbing dust inside the main body of the elevator.

[0017] Furthermore, the vacuum head is connected to the connecting pipe. The threaded sleeves at both ends of the connecting hose are screwed into the connecting pipe, thereby connecting adjacent vacuum heads and enabling multiple vacuum heads to work simultaneously. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-2 In order to improve applicability, this embodiment provides the following technical solution, specifically disclosing: a hoist body 1 and a protective cover 2 installed above the hoist body 1. The protective cover 2 is divided into two parts: a first protective plate 201 and a second protective plate 202. The inner sides of the first protective plate 201 and the second protective plate 202 are fixedly installed with a fixing magnetic block 3 that is magnetically attracted and fixed to the hoist body 1. The sides of the first protective plate 201 and the second protective plate 202 are fixedly installed with a sealing strip 9.

[0027] When using the device, first select an appropriate number of protective covers 2 according to the overall size of the elevator body 1. Then, use the magnetic attraction between the fixed magnetic block 3 and the elevator body 1 to install the protective covers 2 on the outside of the elevator body 1 (multiple protective covers 2 are assembled in contact with each other, and the sealing strip 9 is used to improve the sealing effect at the joint). The protective covers 2 are used to protect the material conveyed by the elevator body 1 and prevent the material from falling from the side of the elevator body 1.

[0028] Example 2: Please refer to Figures 3-5 In order to achieve the purpose of adjusting the spacing, this embodiment provides the following technical solution, which specifically discloses: An adjustment mechanism for adjusting the spacing between the first protective plate 201 and the second protective plate 202 is provided on the inner side of the protective cover 2. The adjustment mechanism includes a limiting block 5 fixedly installed on the inner wall of the first protective plate 201 and the second protective plate 202, and a guide rod 6 slidably connected to the limiting block 5 is installed through the limiting block 5. A fixing bolt 7 for fixing the guide rod 6 is threaded on the outside of the limiting block 5, and a scale mark 8 evenly arranged is provided on the outside of the guide rod 6. A folding cover 4 is fixedly installed between the first protective plate 201 and the second protective plate 202, and the folding cover 4 is made of a pleated rubber material.

[0029] When dealing with a hoist body 1 that is either wide or narrow, the operator first adjusts the distance between the first protective plate 201 and the second protective plate 202. At this time, the folding cover 4 connecting the first protective plate 201 and the second protective plate 202 folds and extends accordingly. Meanwhile, the limiting block 5 slides outside the guide rod 6 (the inside of the limiting block 5 is made of rubber, which generates a certain resistance when squeezing the guide rod 6). At the same time, the scale mark 8 on the outside of the guide rod 6 is used to determine the specific distance between the first protective plate 201 and the second protective plate 202, which is convenient for the operator to operate. Finally, the limiting block 5 and the guide rod 6 are fixed with the fixing bolt 7.

[0030] Example 3: Please refer to Figures 5-6 In order to achieve the purpose of adsorbing dust, this embodiment provides the following technical solution, which specifically discloses: a dust suction head 10 for adsorbing dust is fixedly installed on the inner side wall of the first protective plate 201, and a connecting pipe 11 is fixedly installed on the outer surface of the first protective plate 201. The connecting pipe 11 is connected to the dust suction head 10, and adjacent connecting pipes 11 are connected by a connecting hose 12. A docking sleeve 13 is fixedly installed at the top of the connecting hose 12, and the docking sleeve 13 is threadedly engaged with the connecting pipe 11.

[0031] When lifting some powdery materials (such as lime, cement, etc.), firstly, the two adjacent connecting pipes 11 are connected using the connecting hose 12 (the connecting sleeves 13 at both ends of the connecting hose 12 are threaded into the connecting pipes 11), thereby connecting all the dust suction heads 10. Then, one of the dust suction heads 10 is connected to an external dust removal device (such as a bag filter with a built-in air pump). The negative pressure is used to suck the dust in the main body 1 of the elevator into the dust removal device, ultimately achieving the purpose of suppressing dust.
